"Congelei com medo de me contaminar": tratando um caso de TEPT crônico com imobilidade tônica em uma fisioterapeuta da linha de frente na pandemia de COVID-19 / "I froze for fear of contaminating myself": treating a case of chronic PTSD with tonic immobility in a physiotherapist frontline during COVID-19 pandemic

RESUMO Objetivo: Neste estudo relatamos o caso de uma profissional de saúde com vivência de imobilidade tônica (IT) e posterior desenvolvimento de transtorno de estresse pós-traumático (TEPT) crônico em decorrência de trauma laboral por conta da COVID-19 que recebeu tratamento remoto com terapia cognitivo-comportamental focada no trauma (TCC-FT). Métodos: Relato de caso de uma paciente acompanhada por seis meses após o recebimento de TCC-FT remota. Resultados: Paciente do sexo feminino, de 36 anos, fisioterapeuta, que desenvolveu TEPT crônico e experienciou IT por medo da contaminação por coronavírus. As escalas psicométricas demonstraram que a TCC-FT reduziu consideravelmente os sintomas de TEPT e depressão e aumentou o apoio social e a resiliência. De acordo com o relato, o tratamento melhorou a concentração e a motivação, e reduziu o sentimento de culpa, a irritabilidade, a insegurança e o desconforto em lidar com outras pessoas. Conclusão: Este artigo demonstra que traumas decorrentes da COVID-19 podem ser capazes de desencadear IT e exemplifica um favorável desempenho da TCC-FT na melhoria global da saúde mental dos pacientes com TEPT crônico com vivência de IT.

ABSTRACT Objective: In this study, we report the case of a health professional with experience of tonic immobility (TI) and subsequent development of post-traumatic stress disorder (PTSD) as a result of occupational trauma due to COVID-19 who received remote treatment with Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). Methods: A case report of a patient followed for six months after receiving remote TF-CBT. Results: A 36-year-old female patient, the physiotherapist who developed chronic PTSD and experienced TI for fear of coronavirus contamination. Psychometric scales demonstrated that TF-CBT considerably reduced PTSD and depression symptoms and increased social support and resilience. According to the report, the treatment improved concentration and motivation, and reduced feelings of guilt, irritability, insecurity, and discomfort in dealing with other people. Conclusion: This article demonstrates that trauma resulting from COVID-19 can trigger TI and exemplifies a favorable performance of TF-CBT in the global improvement of the mental health of patients with chronic PTSD who experience TI.

Research progress on factors influencing immobility in the elderly / 中华老年医学杂志

Immobility in older people refers to the loss of mobility, including walking, driving and using public or other forms of transport, and reflects the declining ability of older people to carry out their daily lives.The physical and psychological problems caused by immobility, such as high morbidity rates, worse quality of life and even social isolation, will present serious challenges to the health of older people.Research has shown that disease, exercise & muscle, diet & nutrition, society and other factors all contribute to the onset of immobility in older people.This review focuses on the influencing factors of immobility in older adults.

Muito além do trauma: uma investigação sobre o papel das reações peritraumáticas sobre o transtorno de estresse pós-traumático / Beyond the trauma: an investigation of the role of peritraumatic reactions on posttraumatic stress disorder

O Transtorno de Estresse Pós-Traumático (TEPT) é uma condição debilitante que impacta significativamente a qualidade de vida dos seus portadores. Dentre vários fatores de risco para o TEPT, as reações peritraumáticas (RP), como a imobilidade tônica peritraumática (ITP), dissociação (DP) e reações físicas de pânico (RFP), estão entre as mais investigadas. No entanto, a maioria dos estudos avaliou essas RP separadamente, e o elo entre elas e o TEPT ainda não foi bem compreendido. Portanto, essa tese teve como objetivos: (i) estimar simultaneamente o efeito das três RP sobre o TEPT utilizando um instrumento validado; e (ii) avaliar se há efeito indireto da ITP sobre o TEPT mediado pelo sentimento de culpa/vergonha. Utilizamos modelagem de equações estruturais para analisar dados de 3211 participantes do Rio de Janeiro e de São Paulo. Tratamos as RP como variáveis latentes, selecionando desconfundidores específicos para cada reação. Nossas exposições foram as RP, sendo TEPT o desfecho. Calculamos odds ratios e intervalos de confiança de 95%. Utilizamos o Bayesian Information Criterion para comparar o ajuste de modelos não aninhados. Quando analisadas separadamente, todas as RP alcançaram significância estatística. No entanto, apenas DP (ORDP=1,8; IC95%:1,3-2,4) e RFP (ORRFP=2,5; IC95%:1,8-3,4) permaneceram estatisticamente significativas quando incluímos as três reações em um modelo com seus respectivos desconfundidores e correlações entre elas. Os resultados sugeriram um possível efeito da ITP sobre o TEPT (ORITP=1,4; IC95%:1,0-1,9). As interações entre as RP não foram estatisticamente significativas. Ao investigarmos o sentimento de culpa/vergonha como mediador entre ITP e TEPT, o efeito indireto alcançou apenas significância estatística limítrofe (ORITP(TNIE)=1,1; IC95%:1,0-1,2). Os efeitos direto (ORITP(PNDE)=1,3; IC95%: 0,8-1,8) e total (ORITP(TE)=1,4; IC95%:0,9-1,9) para ITP perderam significância quando todas as RP, seus desconfundidores e correlações entre elas fizeram parte do mesmo modelo. As demais RP, no entanto, permaneceram estatisticamente significativas (ORDP=1,7; IC95%:1,3-2,3 e ORRFP=2,5; IC95%:1,8-3,4). Nossos resultados mostraram que a DP e as RFP aumentaram o risco de TEPT mesmo quando consideradas em conjunto. A ITP pode ter efeito sobre o risco de TEPT, mas esse achado deve ser interpretado com cautela devido a significância limítrofe dessa RP em nosso modelo final. Também não identificamos uma mediação significativa entre ITP e TEPT pelos sentimentos de culpa/vergonha. Contudo, a significância limítrofe encontrada para o efeito indireto demanda investigações adicionais. Nossos achados reforçam a ideia de que as reações peritraumáticas devem ser analisadas e compreendidas como ocorrências simultâneas. Também seria oportuno que estudos envolvendo culpa/vergonha, ITP e TEPT focalizassem traumas caracterizados por aprisionamento e impossibilidade de escapar, dado que estas experiências são apontadas como mais susceptíveis para desencadear a ITP.

Posttraumatic stress disorder (PTSD) is a debilitating condition that greatly impacts quality of life. Among several PTSD risk factors, peritraumatic reactions (PR) such as peritraumatic tonic immobility (PTI), dissociation (PD) and physical panic reactions (PPR) are some of the most investigated. However, several studies have assessed these PR separately, and the pathway connecting them to PTSD is not well understood. Therefore, this thesis aimed to: (i) simultaneously estimate the effect of the three PR on PTSD using a validated instrument; and (ii) assess if there is an indirect effect of PTI on PTSD mediated by feelings of guilt/shame. We used structural equation modelling to analyse data from 3211 participants from Rio de Janeiro and São Paulo. We treated the PR as latent variables and selected specific confounders for each reaction. Our exposures were the PR, and PTSD was the outcome. We calculated odds ratios and 95% confidence intervals for each analysis. We also employed the Bayesian Information Criterion to compare the goodness of fit between non-nested models. Separately, all PR achieved statistically significant results. However, only PD (ORPD=1.8; 95%CI:1.3-2.4) and PPR (ORPPR=2.5; 95%CI:1.8-3.4) remained statistically significant when all three were included in a model with their respective confounders and correlations among all PR. Our findings suggested a possible effect of PTI on PTSD (ORPTI=1.4; 95%CI:1.0-1.9). Interactions between the PR were not statistically significant. When we investigated feelings of guilt/shame as the mediator between PTI and PTSD, the indirect effect achieved a borderline statistical significance (ORPTI(TNIE)=1.1; 95%CI:1.0-1.2). Direct (ORPTI(PNDE)=1.3; 95%CI:0.8-1.8) and total (ORPTI(TE)=1.4; 95%CI:0.9-1.9) effects lost their significance when all PR, their confounders and correlations were included in the same model. The other PR remained statistically significant (ORPD=1.7; 95%CI:1.3-2.3 and ORPPR=2.5; 95%CI:1.8-3.4). Our findings showed PD and PPR to increase the risk of PTSD even when considered in tandem. PTI could have an effect on PTSD, but this must be considered cautiously, as this PR only reached borderline significance in our final model. Feelings of guilt/shame did not significantly mediate PTI's effect on PTSD. However, a borderline statistical significance in the indirect effects warrants further investigation. Our findings reinforce the hypothesis that peritraumatic reactions should be analysed and understood as simultaneous occurrences, not as separate entities. It would also be appropriate for studies concerning guilt/shame, PTI and PTSD to focus on traumas characterized by imprisonment and feelings of inescapability, given that these experiences are allegedly more likely to trigger PTI.

The COVID-19 pandemic and its impact on mental health of healthcare workers / A pandemia de COVID-19 e seu impacto na saúde mental dos profissionais de saúde

ABSTRACT The COVID-19 pandemic has imposed a health crisis around the world. Health professionals are frequently exposed to stressors that put them at high risk for the development or progression of disabling mental disorders, including posttraumatic stress disorder (PTSD). To understand how pandemic stressors have affected the mental health of healthcare workers, our group conducted a longitudinal and nationwide survey. We investigated the occurrence of traumatic events related to the COVID-19 pandemic and the association between exposure to these events and PTSD symptomatology. Importantly, we also investigated factors that might increase or decrease the risk for PTSD. Depression symptoms were also investigated. The results of the first wave of the project were published in a series of three articles, each focused on different risk or protective factors. The results showed that female sex, young age, a lack of adequate personal protective equipment, social isolation and a previous history of mental illness were consistent predictors of PTSD symptoms. Healthcare workers who reported high levels of peritraumatic tonic immobility, a defensive response that is involuntary, reflexive, and evoked by an intense and inescapable threat, also exhibited an increase in the probability of being diagnosed with PTSD. On the other hand, professional recognition had a negative relationship with PTSD and depression symptoms, emerging as a significant protective factor for psychological health. The identification of protective and risk factors in these situations is crucial to guide the adoption of long-term measures in work environments that will enhance the psychological health of these professionals.

RESUMO A pandemia de COVID-19 impôs uma crise de saúde no mundo. Profissionais de saúde foram frequentemente expostos a estressores que os colocam em alto risco para o desenvolvimento ou progressão de transtornos mentais incapacitantes, incluindo o transtorno de estresse pós-traumático (TEPT). Para entender como esses estressores afetaram a saúde mental desses profissionais, nosso grupo realizou um estudo longitudinal nacional. Investigamos a ocorrência de eventos traumáticos especificamente relacionados à pandemia e a associação entre a exposição a esses eventos traumáticos e a sintomatologia do TEPT. É importante ressaltar que também investigamos fatores que podem aumentar ou diminuir o risco de TEPT. Sintomas de depressão também foram investigados. Os resultados da primeira onda do projeto foram publicados em uma série de três artigos, cada um focado em diferentes fatores de risco ou proteção. Os resultados mostraram que sexo feminino, idade jovem, falta de equipamento de proteção individual adequado, isolamento social e história prévia de doença mental foram preditores consistentes de sintomas de TEPT. Os profissionais de saúde que relataram altos níveis de imobilidade tônica, uma resposta peritraumática involuntária e reflexa evocada em situações de ameaça intensa e inescapável, exibiram aumento na probabilidade de um provável diagnóstico de TEPT. Por outro lado, reconhecimento profissional teve relação negativa com sintomas de TEPT e depressão, emergindo como importante fator de proteção para a saúde mental. Identificar fatores protetores ou de risco nessas situações é fundamental para orientar a adoção de medidas de longo prazo nos ambientes de trabalho que melhorem a saúde mental desses profissionais.

Invertendo o enfoque das "crises migratórias" para as "migrações de crise": uma revisão conceitual no campo das migrações / From "migration crisis" to "crisis migration": a conceptual review within the migration studies field / De "crisis migratoria" a "migraciones de crisis": una revisión conceptual en el campo de estudios de las migraciones

O presente artigo se propõe a debater um novo conceito no campo de estudos migratórios - as migrações de crise -, o qual traz à luz os processos, motivos e fatores vivenciados por populações afetadas por crises e que podem contribuir para processos migratórios de indivíduos, famílias e comunidades como um todo. Introduzindo diversas categorias correlatas - como a eventualidade, a imobilidade (ou enclausuramento) e a não escolha -, adota-se um direcionamento metodológico e conceitual que aponta para as crises como propulsoras das migrações. Dessa maneira, busca-se tensionar a ideia de que as migrações geram crises aos Estados-nação receptores de movimentos significativos de pessoas - a qual notavelmente se consolida pela disseminação do termo "crise migratória", em especial, nos discursos políticos e midiáticos correntes. A delimitação do novo conceito proposto e da sua metodologia de estudo pautou-se pela revisão bibliográfica da literatura especializada na área, com foco em pesquisas recentes sobre as migrações de crise e suas implicações tanto na esfera local como na internacional. Ao final do texto, levantamos os desafios e as contribuições de tal conceito, envolvendo debates centrais no campo das migrações, inobstante questões teórico-metodológicas

This article aims to debate a new concept within the migration studies field which is named "crisis migration", shedding light on the processes, motives and factors that influence the movement of populations affected by crisis. Introducing other interrelated categories - such as eventuality, immobility and non-choice - , the article is guided by a methodological and conceptual perspective that understands crisis as a driver to migration. Therefore it seeks to defy the idea that migrations generate crisis to nation-states receiving large contingents of people. This idea has been consolidated by the term "migration crisis" especially disseminated in the midia and political discourses. Our discussion of the new concept was based on bibliographic review, focusing on recent researchs in respect to crisis migration and its unfoldings not only in the local but also in the international scenario. Finally, we bring about the challenges as well as the contributions of this concept, which involve unsolved central debates within the migration field.

Este artículo tiene como objetivo discutir un nuevo concepto en el campo de los estudios migratorios, las migraciones de crisis, que saca a la luz los procesos, los motivos y los factores experimentados por las poblaciones afectadas por las crisis y que pueden contribuir a los procesos migratorios de las personas, las familias y comunidades en su conjunto. Al introducir varias categorías relacionadas, como eventualidad, inmovilidad (o confinamiento) y no elección, se adopta una dirección metodológica y conceptual que apunta a las crisis como motores de la migración. De esta manera, buscamos tensionar la idea de que la migración genera crisis en los Estados-nación que reciben movimientos significativos de personas, lo que se consolida notablemente por la difusión del término crisis migratoria, especialmente en los discursos políticos y mediáticos actuales. La delimitación del nuevo concepto propuesto y su metodología de estudio fue guiada por la revisión bibliográfica de la literatura especializada en el área, con un enfoque en investigaciones recientes sobre migraciones de crisis y sus implicaciones tanto a nivel local como internacional. Al final del texto, planteamos los desafíos y las contribuciones de dicho concepto, involucrando debates centrales en el campo de las migraciones, a pesar de los problemas teóricos y metodológicos que aún no se han superado suficientemente dentro de este.

Clinical outcomes of vocal fold immobility after tracheal intubation / 北京大学学报(医学版)

OBJECTIVE@#To assess the incidence of postoperative vocal cord immobility in patients following endotracheal intubation underwent general anesthesia.@*METHODS@#We retrospectively enrolled patients who underwent surgical procedures with endotracheal intubation under general anesthesia from January 2014 to December 2018 in Peking University First Hospital. Demographic and treatment data were obtained for patients with hoarseness and vocal cord fixation. The incidence of postoperative hoarseness and vocal cord fixation were presented and clinical outcomes were further analyzed.@*RESULTS@#A total of 85 998 patients following tracheal intubation and general anesthesia were enrolled in this study. Hoarseness was observed in 222 (0.26%) patients postoperatively. Sixteen patients (73%) were accomplished with symptoms of choking on water, dysphonia and sore throat. Twenty-nine patients with persistent hoarseness on the third postoperative day needed further treatment by otolaryngologists. Among them, seven patients had pharyngolaryngitis and twenty-two patients (0.026%) were demonstrated postoperative vocal cord immobility. There were seventeen patients (77%) with left-side vocal cord fixation and five patients (23%) with right-side vocal cord fixation. Nine patients were identified with arytenoid dislocation. Seven patients had left vocal cord fixation and two patients had right-side vocal cord fixation. Seven patients were intubated under the guidance of visual laryngoscope. One patient was confirmed difficult airway and intubated with light wand. One patient was inserted with laryngeal mask airway. One patient was suspected to have hoarseness caused by gastric tube before anesthesia. One patient showed simultaneously left recurrent laryngeal nerve abnormality on laryngeal electromyography result. The symptom of hoarseness ranged between 6 and 31 days. Three patients underwent closed reduction under local anesthesia and one patient demonstrated spontaneous recovery. Among the remaining thirteen patients with vocal cord immobility, two patients were demonstrated vocal cord paralysis. Eleven patients underwent neck surgery, thyroid surgery and cardiothoracic surgery and further examinations including laryn-geal electromyography and computed tomography help to determine the diagnosis were not performed. All patients were treated with inhaled corticosteroid conservatively. Five patients had significant improvement of symptom and almost regained normal voice. One patient had slight improvement and sixteen patients were not relieved before discharge.@*CONCLUSION@#Patients with hoarseness and vocal fold immobility after endotracheal intubation should be treated properly and immediately.

Síndrome de inmovilidad en adultos mayores del Policlínico Bernardo Posse del municipio San Miguel del Padrón / Immobilization syndrome in elderly people in "Bernardo Posse" Policlinic in San Miguel del Padron

RESUMEN Fundamento: Dentro de los grandes síndromes geriátricos, la inmovilidad es una de las más graves consecuencias de las enfermedades que puede sufrir el anciano. Objetivo: Caracterizar el comportamiento del síndrome de inmovilidad en los adultos mayores del Grupo Básico de Trabajo n.o 1 del policlínico Bernardo Posse de San Miguel del Padrón. Metodología: Se realizó un estudio descriptivo, retrospectivo, en 145 pacientes con síndrome de inmovilidad, de una población de 160 ancianos desde enero de 2015 a diciembre del 2017. Se determinó el tipo de inmovilidad, y las causas principales, así como las complicaciones. Resultados: El síndrome predominó en pacientes femeninos en edades altas de la vida. El tipo de inmovilidad más frecuente fue la larvada y las causas más frecuentes fueron las enfermedades osteomioarticulares, las infecciones, el cáncer y el síndrome del cuidador. Las complicaciones que predominaron fueron a nivel de los sistemas digestivo, respiratorio, cardiovascular y la piel. Conclusiones: El riesgo de presentar algún tipo de inmovilidad aumenta con la edad y el sexo femenino es más susceptible a este. La inmovilidad es una entidad sindromática que deteriora de manera significativa la calidad de vida de los adultos mayores ya que el anciano inmovilizado es un paciente de alto riesgo para la aparición de complicaciones.

ABSTRACT Background: Within the great geriatric syndromes, immobility is one of the most serious consequences of the diseases that the elderly can suffer. Objective: To characterize the behavior of the immobility syndrome in the elderly from the Basic Working Group No. 1 at Bernardo Posse polyclinic in San Miguel del Padrón. Methodology: A retrospective descriptive study was carried out in 145 patients with immobility syndrome, from a population of 160 elderly people, from January 2015 to December 2017. The type of immobility was determined, as well as the main causes, as well as complications. Results: The syndrome predominated in female patients at high ages of life. The most frequent type of immobility was larvae and the most frequent causes were osteomyoarticular diseases, infections, and cancer also the caregiver syndrome. The predominated complications were at the level of the digestive, respiratory, cardiovascular and skin systems. Conclusions: The risk of presenting some type of immobility increases with age, and the female sex is more susceptible to it. Immobility is a syndromic disease that significantly deteriorates the quality of life of elderly, since the immobilized elderly person is a high-risk patient for complications.

Split cricoídeo posterior endoscópico con injerto de cartílago costal / Endoscopic posterior cricoid split with costal cartilage graft

RESUMEN A pesar de los avances en cirugía de vía aérea, tanto abierta como endoscópica, la inmovilidad bilateral de cuerdas vocales continúa representando un desafio significativo para los cirujanos de vía aérea. Entre las alternativas quirúrgicas existen tanto abordajes endoscópicos como transcervicales, no obstante, la mayoría de estas técnicas modifican estructuralmente regiones de la cuerda vocal y/o aritenoides de manera permanente. La traqueostomía ha sido el tratamiento de elección en niños con inmovilidad bilateral de cuerdas vocales severamente sintomática, sin embargo, el procedimiento ideal debiese establecer una vía aérea adecuada evitando la necesidad de realizar una traqueostomía, y a la vez no generar un deterioro de la función fonatoria. La capacidad de expandir el aspecto glótico posterior sin modificación estructural de aritenoides y/o ligamento vocal ha convertido a la sección cricoidea posterior endoscópica con injerto de cartílago costal en una alternativa quirúrgica atractiva para estos casos. En este trabajo se realiza una revisión de la literatura y presenta un caso tratado mediante esta técnica en el Hospital Guillermo Grant Benavente de Concepción, Chile.

ABSTRACT Despite advances in both open and endoscopic airway surgery, bilateral vocal cord immobility still poses a significant challenge for airway surgeons. Among the surgical alternatives there are both endoscopic and transcervical approaches. However, most of these techniques structurally modify certain regions of the vocal cord and/or arytenoids permanently. Tracheostomy has been the treatment of choice in severely symptomatic children with bilateral immobility of vocal cords. Nevertheless, the ideal procedure should establish an adequate airway, avoiding the need to perform a tracheostomy, and at the same time not causing a deterioration of the phonatory function. The ability to expand the posterior glottis without structural modification of the arytenoids and/or vocal ligament has converted the posterior endoscopic cricoid split with costal cartilage graft into an attractive surgical alternative for these cases. In this article we review the literature and present a case treated by this technique in the Guillermo Grant Benavente Hospital in Concepción, Chile.

Comparative Behavioral Correlation of High and Low-Performing Mice in the Forced Swim Test

Behavioral analysis in mice provided important contributions in helping understand and treat numerous neurobehavioral and neuropsychiatric disorders. The behavioral performance of animals and humans is widely different among individuals but the neurobehavioral mechanism of the innate difference is seldom investigated. Many neurologic conditions share comorbid symptoms that may have common pathophysiology and therapeutic strategy. The forced swim test (FST) has been commonly used to evaluate the “antidepressant” properties of drugs yet the individual difference analysis of this test was left scantly investigated along with the possible connection among other behavioral domains. This study conducted an FST-screening in outbred CD-1 male mice and segregated them into three groups: high performers (HP) or the active swimmers, middle performers (MP), and low performers (LP) or floaters. After which, a series of behavioral experiments were performed to measure their behavioral responses in the open field, elevated plus maze, Y maze, three-chamber social assay, novel object recognition, delay discounting task, and cliff avoidance reaction. The behavioral tests battery revealed that the three groups displayed seemingly correlated differences in locomotor activity and novel object recognition but not in other behaviors. This study suggests that the HP group in FST has higher locomotor activity and novelty-seeking tendencies compared to the other groups. These results may have important implications in creating behavior database in animal models that could be used for predicting interconnections of various behavioral domains, which eventually helps to understand the neurobiological mechanism controlling the behaviors in individual subjects.

Is Forced Swimming Immobility a Good Endpoint for Modeling Negative Symptoms of Schizophrenia? - Study of Sub-Anesthetic Ketamine Repeated Administration Effects

ABSTRACT Immobility time in the forced swimming has been described as analogous to emotional blunting or apathy and has been used for characterizing schizophrenia animal models. Several clinical studies support the use of NMDA receptor antagonists to model schizophrenia in rodents. Some works describe the effects of ketamine on immobility behavior but there is variability in the experimental design used leading to controversial results. In this study, we evaluated the effects of repeated administration of ketamine sub-anesthetic doses in forced swimming, locomotion in response to novelty and novel object recognition, aiming a broader evaluation of the usefulness of this experimental approach for modeling schizophrenia in mice. Ketamine (30 mg/kg/day i.p. for 14 days) induced a not persistent decrease in immobility time, detected 24h but not 72h after treatment. This same administration protocol induced a deficit in novel object recognition. No change was observed in mice locomotion. Our results confirm that repeated administration of sub-anesthetic doses of ketamine is useful in modeling schizophrenia-related behavioral changes in mice. However, the immobility time during forced swimming does not seem to be a good endpoint to evaluate the modeling of negative symptoms in NMDAR antagonist animal models of schizophrenia.

Nitriergic Influence in the Compromised Antidepressant Effect of Fluoxetine in Stressed Mice.

Objective: Investigation of possible nitriergic mechanism involved in the compromised antidepressant effect of fluoxetine in stressed mice.Materials and methods: Male swiss albino mice were used in the present study. Mice were stressed by immobilization of 2hrs. Mice subjected to stress were considered as stressed mice and mice not subjected to stress were considered as unstressed mice. All the treatments were administered intraperitoneally (i.p.) in a fixed volume of 10 ml/kg and the depression like behavioral alterations in unstressed and stressed mice was measured by TST followed by FST. Nitrite levels were measured in brain homogenates to determine the possible involvement of nitriergic mechanism.Results: Present study showed that the 2hrs immobilization significantly increased the immobility period of mice in both TST and FST, with the concurrent increase in the levels of nitrite in the brain of stressed mice as compared to the vehicle treated unstressed mice. Fluoxetine (FLX) (20 mg/kg, i.p.); pyrrolidine dithiocarbamate (PDTC) (100 mg/kg, i.p.) and methylene blue (MB) (100 mg/kg, i.p.) significantly reduced the immobility period of stressed mice in both TST and FST as compared to vehicle treated stressed mice. Pre-treatment with PDTC (100 mg/kg, i.p.) followed by the administration of FLX (20 mg/kg, i.p.) did not significantly alter the immobility period and nitrite levels as compared to the FLX (20 mg/kg, i.p.) treated stressed mice. Pre-treatment with MB (100 mg/kg, i.p.) followed by the administration of FLX (20 mg/kg, i.p.) did not significantly alter the immobility period of mice in TST, but significantly reduced the immobility period of mice in FST as compared to the FLX (20 mg/kg, i.p.) treated stressed mice. Also the pre-treatment with MB (100 mg/kg, i.p.) followed by the administration of FLX (20 mg/kg, i.p.) significantly reduced the nitrite levels as compared to the FLX (20 mg/kg, i.p.) treated stressed mice. Conclusion: It has been concluded that the immobilization stress induced increase production of NO was involved in the compromised antidepressant effect of fluoxetine in stressed mice.

A Comparative Study of Antidepressant Activity of Aqueous Extract of Berberis Aristata with Fluoxetine in Albino Rats

Introduction: Depression belongs to the heterogeneous group of mental disorders characterized by extreme exaggerations and disturbance of mood, which adversely affect cognition and psychomotor functions. It results from abnormal brain mechanisms functionally deficient monoaminergic (noradrenaline and/or 5-hydroxytryptamine) transmission in the central nervous system. Aims and Objectives: To evaluate comparatively the Anti- depressant activity of Berberis aristata (Daru haridra) in  albino rats after inducing experimental depression using different methods. Materials and methods: The antidepressant activity of aqueous extract of berberis aristata was screened by tail suspension method and the forced swimming test and compared with the control and standard drug (fluoxetine) for two weeks. Group1- were kept as control. Group 2- were treated with fluoxetine in a dose of 14mg/kg/day as standard drug for one week. Group 3, 4 and 5- were given aqueous extract of berberis aristata intraperitoneally in three graded doses 400,800 and 1600mg/kg/day respectively for two weeks. Results: berberis aristata exhibits antidepressant activity depicted by reduction in the immobility time when compared to the control group. The onset of action was after few days according to the dose of the test drugs following their administration. The effect is comparable with that of standard drug fluoxetine which may be attributed to the phytoconstituents like berberine, berbamine and palmitine, among them most probably with berberine alkaloid. The berberine alkaloid is known to inhibit the monoamine oxidase enzyme particularly monoamine oxidase- A isoform.  berberine influenced either dopaminergic system by monoamine oxidase-B inhibiting property or by blocking the reuptake of dopamine by inhibiting its transporter.   Conclusion:  Berberis aristata has significant antidepressant activity demonstrated by tail suspension and forced swimming test compared to the test drug.

Tratamiento de la inmovilidad cordal bilateral / Bilateral vocal fold immobility treatment

La inmovilidad bilateral de las cuerdas vocales en aducción puede ser provocada por diversas etiologías y pone en riesgo la vida de los pacientes por la disnea grave que puede ocasionar. Existen diversas técnicas quirúrgicas para aumentar el espacio glótico, entre las que prevalecen las cirugías transorales que resecan tejido. El objetivo del presente trabajo es determinar la tasa de resolución de la disnea inspiratoria o decanulación, en pacientes con inmovilidad cordal bilateral en aducción, tratados mediante cordotomía posterior y aritenoidectomía parcial. Fueron tratados en este estudio 17 enfermos por inmovilidad bilateral de las cuerdas vocales en aducción, mediante cordotomía posterior y aritenoidectomía parcial medial por vía transoral con láser de CO2 , cauterio y radiofrecuencia. Ocho pacientes tuvieron traqueostomía. El 75% fueron decanulados. El 100% de los pacientes sin traqueostomía mejoraron la disnea inspiratoria y no tuvieron limitación para las actividades de su vida cotidiana. Como conclusión del trabajo, se determinó que la cordotomía posterior y la aritenoidectomía parcial por vía transoral fueron muy eficaces para mejorar el calibre de la vía aérea superior, con baja morbilidad y sin complicaciones.

Bilateral medial vocal fold immobility, can be caused by various etiologies and can lead to severe dyspnea that may risk patients life. There are several surgical techniques for increasing the glottic space, prevailing transoral surgeries that remove tissue. The objective of this study is to determine the rate of resolution of inspiratory dyspnea and decanulation in patients with bilateral vocal cord immobility in adduction. In this study 17 patients diagnosed with bilateral vocal fold immobility in adduction were treated with posterior cordotomy and partial medial arytenoidectomy with transoral approach, using CO2 laser, radiofrequency or electrocautery. Eight of our patients were tracheostomized. Six of the tracheostomized patients had their tracheostomies removed (6 out of 8, 75%). Nine without tracheostomy showed improvement of inspiratory dyspnea and had no limitation on their daily lives activities. (9 out of 9, 100%). As a conclussion, we can say that transoral cordotomy and partial arytenoidectomy were very effective in improving the caliber of the upper airway, with low morbidity and no complications. (AU)

A imobilidade em instituição de longa permanência: compreendendo o desafio vivenciado pelas equipes de saúde / The immobility in the long term institution for elderly: understanding the challenge experienced by health staff

O crescimento do número de pessoas idosas foi acompanhado por um aumento de comorbidades geradoras de imobilidade e de institucionalização. Objetivamos identificar as variáveis associadas à imobilidade e à realização das atividades básicas da vida diária (AVDs) em uma Instituição de Longa Permanência (ILPI). A média etária das idosas institucionalizadas foi de 72,8 anos, sendo 40,3% dependentes quanto a AVDs. Os fatores associados à imobilidade foram: doenças reumatológicas, gastrointestinais e incontinência urinária (p<0,05).

The increasing number of elderly has growth the prevalence of comorbidities that generate immobility and of institutionalization. We aimed identify the variables associated with immobility and performingbasic activities of daily living (AVD) on a ILP. The average age of institutionalized elderly was 72.8 years and 40.3% were dependent about the AVDs.The factors associated with immobility were: rheumatic diseases, gastrointestinal and urinary incontinence (p <0.05).

Hipnose, imobilidade tônica e eletroencefalograma / Hypnosis, tonic immobility and electroencephalogram

OBJETIVO: Apresentar uma revisão sobre as características da atividade elétrica cerebral que acompanha a hipnose animal, estado induzido em laboratório em mamíferos por manipulações experimentais, bem como sobre as alterações encontradas no EEG durante o estado de hipnose, visando à discussão dos resultados encontrados na busca de evidências dos fundamentos filogenéticos que possam conduzir ao entendimento dos rudimentos neurais da hipnose humana. MÉTODO: Livros e bases eletrônicas de dados foram consultados. Critério de inclusão: artigos originais publicados entre 1966-2012. Critério de exclusão: artigos que se afastavam da visão eletroneurofisiológica da hipnose. RESULTADOS: Foram encontradas 662 referências, tendo sido selecionados os artigos e livros referenciados. Além desses artigos, foi incluído no estudo o artigo de Hoagland, publicado em 1928, que é um clássico na área de imobilidade tônica em vertebrados. CONCLUSÕES: O estado de hipnose humano resulta de processamentos em inúmeros circuitos paralelos distribuídos em uma complexa rede neuronal, envolvendo, dessa forma, uma ampla área do encéfalo. Na trajetória evolutiva, a grande ampliação dos recursos corticais pode ter tornado as respostas de imobilidade tônica passíveis de modulação consciente, respostas essas ainda presentes nos humanos e que se manifestam involuntariamente em situações de grande ameaça. Vários estudos têm evidenciado mecanismos neurofisiológicos capazes de reforçar a visão da hipnose não só como um eficiente recurso para procedimentos médicos e odontológicos, funcionando como auxiliar na analgesia e sedação, mas também como excelente ferramenta psicoterapêutica.

OBJECTIVE: To present a revision on characteristics of electric brain activity accompanying the animal hypnosis, state induced in laboratory in mammals by means experimental manipulation, as well as on alterations found in EEG during hypnosis, aiming to find phylogenetic basis that could conduct us to the understanding of neural rudiments of the hypnosis state. METHOD: Books and electronics data basis were consulted. Inclusion criteria: original articles published between 1966-2012. Exclusion criteria: articles deviating from electro-neurophysiological hypnosis vision. RESULTS: It was found 662 articles in journals and books, and references show those chosen. In addition, we included the Hoagland' paper published in 1928, which is a classical paper about tonic immobility in vertebrates. CONCLUSIONS: Human hypnosis state results from processing of several parallel circuits distributed in a complex neuronal network, involving a wide area of encephalon. In the evolution, the enlargement of the brain cortex can have made possible the conscious control of tonic immobility responses, which are still presents in human occurring under extreme life threat. Studies have evidenced electro-neurophysiological mechanisms able to support the vision of hypnosis as not only an efficient recourse in medical and dental procedures, auxiliary in analgesia and sedation, but also as excellent tool for psychotherapy. In the evolution of humans, the enlargement of the brain cortex could be possible the conscious control of tonic immobility responses.

Peritraumatic tonic immobility is associated with posttraumatic stress symptoms in undergraduate Brazilian students / A imobilidade tônica peritraumática está associada aos sintomas do transtorno de estresse pós-traumático em estudantes brasileiros de graduação

OBJECTIVE: Tonic immobility is a defensive reaction occurring under extreme life threats. Patients with posttraumatic stress disorder (PTSD) reporting peritraumatic tonic immobility show the most severe symptoms and a poorer response to treatment. This study investigated the predictive falue of tonic immobility for posttraumatic stress symptoms in a non-clinical sample. METHODS: One hundred and ninety-eight college students exposed to various life threatening events were selected to participate. The Posttraumatic Stress Disorder Checklist - Civilian Version (PCL-C) and tonic immobility questions were used. Linear regression models were fitted to investigate the association between peritraumatic tonic immobility and PCL-C scores. Peritraumatic dissociation, peritraumatic panic reactions, negative affect, gender, type of trauma, and time since trauma were considered as confounding variables. RESULTS: We found significant association between peritraumatic tonic immobility and PTSD symptoms in a non-clinical sample exposed to various traumas, even after regression controlled for confounding variables (β = 1.99, p = 0.017). CONCLUSIONS: This automatic reaction under extreme life threatening stress, although adaptive for defense, may have pathological consequences as implied by its association with PTSD symptoms.

OBJETIVO: A imobilidade tônica é uma resposta defensiva que ocorre sob ameaça extrema à vida. Pacientes com transtorno de estresse pós-traumático (TEPT) que relatam imobilidade tônica peritraumática são os que apresentam os sintomas mais graves e a pior resposta ao tratamento. Este estudo investigou o valor preditivo da imobilidade tônica para os sintomas de TEPT em uma amostra não clínica. MÉTODOS: Os participantes da pesquisa foram 198 estudantes universitários expostos a traumas diversos. A versão brasileira do Post-Traumatic Stress Disorder Checklist Civilian Version (PCL-C) e questões referentes à imobilidade tônica foram empregadas. Modelos de regressão linear foram utilizados para investigar a associação dos sintomas de estresse pós-traumático com a imobilidade tônica peritraumática. Foram consideradas como variáveis de confusão a dissociação peritraumática, as reações físicas de pânico peritraumática, o traço de afeto negativo, o gênero, o tipo de trauma e o tempo de trauma. RESULTADOS: Encontrou-se uma associação significativa entre a imobilidade tônica peritraumática e os sintomas de TEPT em uma amostra não clínica exposta a traumas diversos mesmo quando controlada por variáveis de confusão (β = 1,99; p = 0,017). CONCLUSÕES: Esta reação defensiva que ocorre sob intensa ameaça, apesar de adaptativa para a defesa, pode ter consequências patológicas como sugere sua associação aos sintomas de TEPT.

Results (①) The immobility time of BALB/C during the daytime( ( 142.42 ± 33.58) s) was significantly increased than that at night ( ( 104.89 ± 34.33 ) s). (② The immobility time of Kunming mice( (91.95 ± 40.32) s) was significantly decreased than that of BALB/C mice ( ( 142.42 ± 33.58 ) s). (③)The immobility time under the water temperature of 22 C ( ( 92.24 ± 25.81 ) s) was significant longer than that under the water temperature of 32C ( (60.72 ± 11.11 ) s). Conclusion BALB/C stain,male mice,daytime and water temperature of 22℃ should be chosen in the FST.

Inclusão da camomila no desempenho, comportamento e estresse em codornas durante a fase de recria / Chamomile inclusion on performance, behavior and stress in immature quails

Este estudo teve como objetivo avaliar o efeito da Matricaria chamomila sobre o estresse de codornas japonesas na fase de recria (28 a 42 dias de idade). Foram utilizadas 192 codornas com 28 dias de idades, distribuídas em blocos casualizados e submetidas às dietas com 0, 250, 500 e 750mg de camomila/kg de ração, totalizando quatro tratamentos, com oito repetições e seis aves por parcela. Foram avaliados os parâmetros de desempenho (consumo diário de ração, conversão alimentar e ganho de peso), comportamentais (tempo em imobilidade tônica, ferimentos corporais e agressividade) e fisiológicos (concentração plasmática de corticosterona e relação heterófilo:linfócito). Os resultados obtidos demonstraram que a camomila adicionada na dieta não foi capaz de alterar os parâmetros de desempenho, bem como os de comportamento e fisiológicos.

The objective of this study was to test the effect of Matricaria chamomila on the stress of the Japanese quails in the rearing period. In the rearing phase, from 28 to 42 days old, 192 quails were lodged to cages and allotted to completely randomized blocks design, with four diets (0; 250; 500 and 750mg of chamomile/kg of ration), with eight replicates and six birds per cage. Performance (feed intake, body weight gain, and feed conversion ratio), behavior (body injury, tonic immobility and focal observation) and physiological parameters (corticosterone plasmatic and heterophil/lymphocyte ratio) were evaluated. The tested chamomile levels did not affect performance, behavior and physiological parameters of quails in the rearing phase.
