Influence of educational status on executive function and functional balance in individuals with Parkinson disease.

OBJECTIVE: This study investigated whether educational status influenced how people with Parkinson disease (PD) performed on Parts A, B, and DELTA of the Trail Making Test (TMT) and on the Berg Balance Scale (BBS). BACKGROUND: Recent studies have shown that educational status may influence cognitive and motor test performance. METHODS: We gave the TMT and the BBS to assess executive function and functional balance in 28 people with PD (Hoehn and Yahr score between 2 and 3) and 30 healthy elderly people. Participants reported their number of years of formal education. We divided each group of participants by educational status: low (4 to 10 years of education) or high (≥11 years). RESULTS: In both the PD (P=0.018) and control (P=0.003) groups, participants with low educational status performed worse on the TMT Part B than did those with high educational status. Within the PD group, the less-educated participants scored worse on the BBS than did the more educated (P<0.001); this difference was not significant between the more- and less-educated controls (P=0.976). CONCLUSIONS: Whether or not they had PD, less-educated people performed worse than more-educated people on the TMT Part B. Educational status affected executive function, but PD status did not. Among individuals with PD, educational status influenced functional balance.

Family grief during the COVID-19 pandemic: a meta-synthesis of qualitative studies.

The COVID-19 pandemic has led to a public health crisis, with increases in the number of deaths. As a result, the number of bereaved people has increased significantly. In addition, the measures adopted to control the spread of virus have triggered changes in the subjective and collective bereavement experiences. This systematic literature review aims to summarize and reinterpret the results of qualitative studies on the experience of losing family members during the pandemic by a thematic synthesis. The searches were performed in the Web of Science, Scopus, PubMed/MEDLINE, CINAHL, PsycINFO, and LILACS databases. Among 602 articles identified, 14 were included. Evidence was assessed using the Critical Appraisal Skills Programme tool. Two descriptive themes related to the objective were elaborated in addition to one analytical theme, namely: "Pandemic grief: lonely and unresolved". These themes proved to be interrelated and indicate that experiences of loss in this context were negatively impacted by the imperatives of physical distance, restriction of hospital visits, technology-mediated communication, and prohibition or restriction of funerals. These changes resulted in experiences marked by feelings of loneliness and helplessness, which should be considered when planning intervention strategies that favor communication between family members with the afflicted loved one and with the health care team, enabling welcoming and creating alternatives for farewell rituals. The findings may support further research to test intervention protocols, especially to guide public policies and promote psychological support to bereaved family members after their loss.

Effects of resistance training on postural control in Parkinson's disease: a randomized controlled trial.

BACKGROUND: Postural instability affects Parkinson's disease (PD) patients' postural control right from the early stages of the disease. The benefits of resistance training (RT) for balance and functional capacity have been described in the literature, but few studies have been conducted showing its effects on PD patients' postural control. OBJECTIVE: To investigate the effects of a three-month RT intervention on static posturography (SP) measurements and clinical functional balance assessment among PD patients. METHODS: Seventy-four patients were randomly assigned to a three-month RT intervention consisting of using weightlifting machines at a gym (gym group) or RT consisting of using free weights and elastic bands (freew group), or to a control group. The participants were evaluated at baseline, three months and six months. We evaluated changes of SP measurements under eyes-open, eyes-closed and dual-task conditions (primary endpoint), along with motor performance and balance effects by means of clinical scales, dynamic posturography and perceptions of quality of life (secondary endpoints). RESULTS: There were no significant interactions in SP measurements among the groups. Unified Parkinson Disease Rating Scale (UPDRS-III) motor scores decreased in both RT groups (p<0.05). Better perceived quality of life for the mobility domain was reported in the gym group while functional balance scores improved in the freew group, which were maintained at the six-month follow-up (p<0.05). CONCLUSIONS: This study was not able to detect changes in SP measurements following a three-month RT intervention. Both RT groups of PD patients showed improved motor performance, with positive balance effects in the freew group and better perceived quality of life in the gym group.

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

Resumo: 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.

Abstract: 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.

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.

Is virtual reality beneficial for dual-task gait training in patients with Parkinson's disease? A systematic review.

This systematic review examined the evidence about the effects of virtual reality (VR) on dual-task gait training in Parkinson's disease (PD). METHODS: this study (PROSPERO registration CRD42019114736) aimed to answer the question: "Is VR beneficial for dual-task gait training in patients with PD?" We searched for studies from 2008 to 2018 on Medline/PubMed and Web of Science/Web of knowledge databases. The keywords were Parkinson AND gait training AND virtual reality OR Parkinson AND gait training AND game. A total of 55 articles were retrieved, of which 11 systematic reviews, 11 opinions, letters to the editor, posters or conferences abstracts and 17 studies not evaluating the effects of VR gait training were excluded. Three further studies addressing VR dual-task gait training in PD (found in references of studies selected) were also included. Therefore, 19 studies were included and analysed. RESULTS: all studies reported gait improvement after VR training. Many clinical scales were used, hampering comparison of the effects of each protocol. CONCLUSION: VR dual-task gait training should be part of rehabilitation protocols for PD. The studies showed that VR training was effective, although specific guidelines have not yet been established.

Essa revisão sistemática examinou as evidências sobre os efeitos da realidade virtual (RV) no treinamento de marcha com tarefa-dupla na doença de Parkinson (DP). MÉTODOS: esse estudo (registro PROSPERO: CRD42019114736) visou responder à questão: "A RV é benéfica no treinamento de marcha com tarefa-dupla em pacientes com DP?" A busca, de 2008 a 2018, foi feita nos bancos de dados Medline/PubMed e Web of Science/Web of Knowledge. Os descritores foram Parkinson, treinamento de marcha, realidade virtual e jogos eletrônicos. Foram encontrados 55 artigos e eliminadas 11 revisões sistemáticas, 11 cartas ao editor, resumos de pôsteres ou conferências e 17 estudos que não avaliaram os efeitos do treinamento da marcha em RV. Três outros estudos (encontrados nas referências dos estudos selecionados) foram incluídos porque também abordaram o treinamento de marcha com dupla tarefa de RV em DP. Portanto, 19 estudos foram incluídos e analisados. RESULTADOS: todos os estudos relataram melhora da marcha após o treinamento com RV. Muitas escalas clínicas foram usadas e foi difícil comparar os efeitos de cada protocolo. CONCLUSÃO: RV deve fazer parte dos protocolos de reabilitação em DP. O treinamento com RV é eficaz, embora recomendações específicas ainda não tenham sido estabelecidas.

Relationship Between Posturography, Clinical Balance and Executive Function in Parkinson´s Disease.

This study aimed to evaluate the relationship between posturography, clinical balance, and executive function tests in Parkinson´s disease (PD). Seventy-one people participated in the study. Static posturography evaluated the center of pressure fluctuations in quiet standing and dynamic posturography assessed sit-to-stand, tandem walk, and step over an obstacle. Functional balance was evaluated by Berg Balance Scale, MiniBESTest, and Timed Up and Go test. Executive function was assessed by Trail Making Test (TMT) and semantic verbal fluency test. Step over obstacle measures (percentage of body weight transfer and movement time) were moderately correlated to Timed Up and Go, part B of TMT and semantic verbal fluency (r > 0.40; p < 0.05 in all relationships). Stepping over an obstacle assesses the responses to internal perturbations. Participants with shorter movement times and higher percentage of body weight transfer (higher lift up index) on this task were also faster in Timed Up and Go, part B of TMT, and semantic verbal fluency. All these tasks require executive function (problem solving, sequencing, shifting attention), which is affected by PD and contribute to postural assessment.

"Você Deixa de ser uma Pessoa com Direitos a Partir do Momento em que Fala que é Lésbica": Violência de Gênero Contra Mulheres Lésbicas / "You Stop Being a Person with Rights When you Say You are a Lesbian": Gender Violence Suffered Against Lesbian Women

Mulheres cisgênero lésbicas são confrontadas em seu cotidiano com situações de dupla violência, relacionadas à desqualificação e desvalor atribuídos tanto ao gênero como à orientação sexual. Este estudo teve por objetivo compreender os significados atribuídos às experiências de preconceito e discriminação sofridas por mulheres lésbicas de camadas médias. Trata-se de um estudo clínico-qualitativo fundamentado no olhar interseccional dos estudos de gênero. Participaram seis mulheres brancas de 22 a 59 anos de camadas médias, que se autoidentificavam como lésbicas. Para construção do corpus de análise foram realizadas entrevistas individuais gravadas em áudio. Os dados foram analisados e discutidos na perspectiva da análise temática reflexiva. Foram construídas cinco categorias: ambiente de trabalho, família de origem, relações de amizade, serviços de saúde e pessoas desconhecidas. Os resultados mostram que pessoas que perpetram violência contra lésbicas não toleram a possibilidade de que duas mulheres possam manter relacionamento afetivo-sexual e se utilizam de estratégias de apagamento (insultos, deboche, desrespeito, indiferença) para depreciá-las, invisibilizá-las e discriminá-las. Os ataques recorrentes às lesbianidades têm como função manter a hegemonia do modelo heterocentrado. Examinar os significados atribuídos às experiências de preconceito e discriminação sofridas por mulheres lésbicas pode encorajar o desenvolvimento de intervenções culturalmente sensíveis e a efetivação de políticas públicas voltadas a essa população.

Cisgender lesbian women face situations of double violence in their daily lives with situations of double violence, related to the disqualification and devaluation attributed to both gender and sexual orientation. This study aimed to understand the meanings attributed to middle-class lesbian women's experiences of prejudice and discrimination. This is a clinical qualitative study based on the intersectional look of gender studies. Six white, middle-class women ages 22 to 59, who self-identified as lesbians, participated. Individual interviews were conducted and recorded to create the analysis corpus. The data were analyzed and discussed from the perspective of reflective thematic analysis. Five categories were constructed: work environment, family of origin, friendship relations, health services, and unknown people. The results show that people who perpetrate violence against lesbians do not tolerate the possibility that two women can have an affective-sexual relationship and use erasure strategies (insults, debauchery, disrespect, indifference) to depreciate, invisibilize them, and discriminate against them. The recurrent attacks on lesbianities have the function of maintaining the hegemony of the heterocentric model. Examining the meanings attributed to the experiences of prejudice and discrimination suffered by lesbian women can encourage the development of culturally sensitive interventions and public policies targeting this population.

Family grief during the COVID-19 pandemic: a meta-synthesis of qualitative studies / Luto familiar durante a pandemia da COVID-19: uma metassíntese de estudos qualitativos / Duelo familiar durante la pandemia de COVID-19: una metasíntesis de estudios cualitativos

A pandemia da COVID-19 causou uma crise de saúde pública com o aumento no número de mortes. Como resultado, o número de pessoas em luto aumentou significativamente. Além disso, as medidas adotadas com o objetivo de controlar a propagação do vírus desencadearam mudanças nas experiências subjetivas e coletivas de luto. Esta revisão sistemática da literatura teve como objetivo resumir e reinterpretar os resultados de estudos qualitativos sobre a experiência de luto devido à perda familiar durante a pandemia, por meio de uma síntese temática. As buscas foram feitas nas bases de dados Web of Science, Scopus, PubMed/MEDLINE, CINAHL, PsycINFO e LILACS. Dos 602 artigos identificados, 14 foram incluídos. As evidências foram avaliadas utilizando-se a ferramenta Critical Appraisal Skills Programme. Foram elaborados dois temas descritivos relacionados ao objetivo e um tema analítico, nomeado: "Luto pandêmico: solitário e inacabado". Esses temas mostraram-se inter-relacionados e indicam que, nesse contexto, as exigências de distância física, a restrição de visitas hospitalares, a comunicação mediada por tecnologia e a proibição ou restrição de rituais fúnebres impactaram negativamente as experiências de perda. Essas mudanças resultaram em experiências marcadas por sentimentos de solidão e desamparo, que devem ser consideradas no planejamento de estratégias de intervenção que favoreçam a comunicação entre os familiares e o ente querido acometido e com a equipe de saúde, possibilitando o acolhimento e a criação de alternativas para os rituais de despedida. Os resultados podem subsidiar novas pesquisas para testar protocolos de intervenção, especialmente para orientar políticas públicas e promover apoio psicológico ao familiar enlutado após a perda.

La pandemia de COVID-19 ha provocado una crisis de salud pública, con un aumento del número de muertes. Como consecuencia, el número de personas en duelo ha aumentado considerablemente. Además, las medidas adoptadas para controlar la propagación del virus han provocado cambios en las experiencias de duelo subjetivas y colectivas. Esta revisión sistemática de la literatura pretende resumir y reinterpretar los resultados de los estudios cualitativos sobre la experiencia de duelo por pérdida familiar durante la pandemia a través de una síntesis temática. Las búsquedas se realizaron en las bases de datos Web of Science, Scopus, PubMed/MEDLINE, CINAHL, PsycINFO y LILACS. De los 602 artículos identificados, se incluyeron 14. La evidencia se evaluó mediante la herramienta Critical Appraisal Skills Programme. Se elaboraron dos temas descriptivos relacionados con el objetivo y un tema analítico, a saber: "Duelo pandémico: solitario e inacabado". Estos temas resultaron estar interrelacionados e indican que las experiencias de pérdida en este contexto se vieron negativamente afectadas por los imperativos de la distancia física, la restricción de las visitas al hospital, la comunicación mediada por la tecnología y la prohibición o restricción de los rituales funerarios. Estos cambios se tradujeron en experiencias marcadas por sentimientos de soledad y desamparo, que deben tenerse en cuenta a la hora de planificar estrategias de intervención que favorezcan la comunicación de los familiares con el familiar afectado y con el equipo sanitario, posibilitando la acogida y creando alternativas para los rituales de despedida. Los resultados pueden respaldar nuevas investigaciones para probar protocolos de intervención, especialmente para orientar las políticas públicas y promover el apoyo psicológico al familiar en duelo tras la pérdida.

Cognitive or Cognitive-Motor Executive Function Tasks? Evaluating Verbal Fluency Measures in People with Parkinson's Disease.

INTRODUCTION: Executive function deficits are observed in people with Parkinson's disease (PD) from early stages and have great impact on daily living activities. Verbal fluency and oral diadochokinesia involve phonarticulatory coordination, response inhibition, and phonological processing and may also be affected in people with PD. This study aimed to describe the performance of PD patients and an age- and education-matched control group on executive function, verbal fluency, and oral diadochokinesia tests and to investigate possible relationships between them. METHODS: Forty people with PD and forty controls were evaluated with Trail Making Test (TMT, executive function) and phonemic/semantic verbal fluency and oral diadochokinesia (/pataka/) tests. Groups were compared by ANOVA and relationships were investigated by Pearson tests. RESULTS: People with PD showed longer times in parts A and B of TMT. They also said fewer words in phonemic/semantic verbal fluency tests and less syllables in the diadochokinesia test. Oral diadochokinesia strongly correlated to parts A and B of TMT and to phonemic verbal fluency. CONCLUSION: Oral diadochokinesia was correlated to executive function and verbal fluency. The cognitive-motor interaction in verbal fluency and oral diadochokinesia must be considered not to overestimate the cognitive or motor impairments in people with PD.

O trabalho do luto por suicídio: uma leitura Kleiniana / The grieving process after a suicide: a Kleinian reading / El trabajo de duelo por suicidio: una lectura Kleiniana

A perda da pessoa amada é uma experiência que mobiliza intensa dor emocional, potencializada por fantasias inconscientes de quem a vivencia. O enlutado acredita que seus objetos bons foram perdidos e que os objetos maus se tornaram dominantes. Isso coloca o mundo interno em perigo iminente de se desintegrar. A resolução se dá quando o sujeito é capaz de restaurar seu vínculo amoroso com o objeto por meio da reparação. O objetivo deste estudo é analisar os componentes psíquicos em jogo no processo de luto por suicídio, sob a ótica da teoria psicanalítica de Melanie Klein. Para tanto investiga-se o enlutamento na perspectiva de um personagem de ficção, protagonista de um filme de animação japonesa que tematiza os diversos estágios do trabalho de luto. Com apoio da família e dos amigos, a aceitação da perda da pessoa querida pôde se estabelecer gradualmente no mundo interno, possibilitando que o personagem adquirisse maior confiança em suas tendências construtivas. O filme mostra como a experiência do luto por suicídio, por mais desafiadora que seja, pode ser elaborada de uma forma saudável, resultando em fortalecimento do ego e crescimento emocional dos sobreviventes.

The loss of a loved one is an experience that mobilizes intense emotional pain, potentiated by unconscious fantasies of those who experience it. The bereaved person believes that their good objects have been lost and that the bad objects have become dominant. This puts the internal world in imminent danger of disintegrating. Resolution occurs when the subject is able to restore his or her love bond with the object through reparation. This study aims to analyze the psychic components at stake in the grieving process experienced after the suicide of a loved one from Melanie Klein's psychoanalytic theory point of view. To this end, we investigate the bereavement of a fictional character, the protagonist of a Japanese animated film that deals with the various stages of mourning. With the support of family and friends, the acceptance of the loss of the loved one was gradually established in the internal world, allowing the character to acquire more confidence in his constructive tendencies. The film shows how the experience of mourning by suicide, as challenging as it may be, can be healthily elaborated, resulting in ego strengthening and emotional growth for the survivors.

La pérdida del ser querido es una experiencia que moviliza un intenso dolor emocional, potenciado por las fantasías inconscientes de quien lo vive. La persona afligida cree que sus objetos buenos se han perdido y que los objetos malos se han vuelto dominantes. Esto hace que el mundo interno esté en peligro inminente de desintegración. La resolución se produce cuando el sujeto es capaz de restaurar su vínculo amoroso con el objeto a través de la reparación. El objetivo de este estudio es analizar los componentes psíquicos en juego en el proceso de duelo por suicidio desde la perspectiva de la teoría psicoanalítica de Melanie Klein. Para ello, se investiga el duelo de un personaje de ficción, protagonista de una película de animación japonesa que tematiza las distintas etapas del duelo. Con el apoyo de la familia y los amigos, la aceptación de la pérdida del ser querido se estableció gradualmente en el mundo interno, lo que permitió al personaje adquirir una mayor confianza en sus tendencias constructivas. La película muestra cómo la experiencia del duelo por suicidio, por muy desafiante que sea, puede elaborarse de forma saludable, dando como resultado el fortalecimiento del ego y el crecimiento emocional de los supervivientes.

Aplicação simultânea de estimulação transcraniana por corrente contínua cerebelar anódica para reabilitação do equilíbrio na ataxia cerebelar: relato de caso / Application of add-on anodal cerebellar direct current stimulation for balance rehabilitation in cerebellar ataxia: a case report

INTRODUÇÃO: As ataxias cerebelares são um extenso grupo de doenças que causam diversos distúrbios na marcha e no equilíbrio, e que comprometem seriamente a qualidade de vida, sem opções de tratamento eficazes. A cinesioterapia é a base de programas multifacetados que incorporam mais de um enfoque, como o treinamento de coordenação e equilíbrio. Recentemente, a estimulação transcraniana por corrente contínua (tDCS) sobre o cerebelo surgiu como uma intervenção para melhorar os distúrbios do equilíbrio. OBJETIVO: Descrever a aplicação simultânea de tDCS anódica cerebelar e cinesioterapia, em sessões múltiplas diárias para reabilitação da ataxia cerebelar. MATERIAIS E MÉTODOS: Este relato de caso incluiu um paciente do sexo masculino, de 34 anos, com história de ataxia espinocerebelar há 10 anos. Seus principais objetivos eram melhorar a marcha e o equilíbrio. Ele apresentava ataxia axial e apendicular, dificuldades na marcha e no equilíbrio. O protocolo de estimulação do cerebelo consistiu na aplicação de tDCS por 20 minutos, 2mA, diariamente, durante duas semanas, com ânodo posicionado sobre o ínion e cátodo sobre o músculo deltóide direito. A cinesioterapia simultânea incluiu exercícios funcionais progressivos com objetivo principal de treinamento de equilíbrio. RESULTADOS: A melhora clínica foi particularmente evidenciada por uma redução de 4 pontos na Escala para Avaliação e Graduação da Ataxia após 10 sessões, enquanto a literatura recomenda a eficácia de uma nova terapia que retardaria a progressão da ataxia em 1 ponto por ano. CONCLUSÃO: Nossos resultados sugerem que a associação entre tDCS e cinesioterapia foi eficaz neste paciente; as sessões de tDCS foram seguras e bem toleradas e podem ter desempenhado um papel na melhora nos testes funcionais. Novos estudos controlados envolvendo um número maior de pacientes são necessários para analisar os benefícios destas técnicas combinadas para maximizar a reabilitação motora nesta população.

INTRODUCTION: Cerebellar ataxias are an extensive group of diseases, which cause many disorders in gait and balance that seriously impair quality of life, and without effective treatment options. Kinesiotherapy is the basis of multifaceted programs that incorporate more than one focus, such as coordination and balance training. Recently, transcranial direct current stimulation (tDCS) over the cerebellum has emerged as an intervention to improve balance disorders. OBJECTIVE: To describe a daily multiple session's simultaneous application of anodal cerebellar tDCS to kinesiotherapy for rehabilitation in cerebellar ataxia. MATERIALS AND METHODS: This case report included a 34-year-old male patient with a 10-year history of spinocerebellar ataxia. His main goals were to improve his walking ability and balance. He presented with axial and appendicular ataxia, impaired gait, and balance. The protocol used to stimulate the cerebellum consisted of twenty-minute tDCS, 2mA, daily applied, over two weeks, with anode positioned over the inion and cathode over the right deltoid muscle. Simultaneous kinesiotherapy included progressive functional exercises with the main objective of balance training. RESULTS: Clinical improvement was particularly evidenced by a 4-point reduction in the Scale for the Assessment and Rating of Ataxia after ten sessions, while literature recommends efficacy of a new therapy that would retard ataxia progression by 1 point per year. CONCLUSION: Our results suggest that the association between tDCS and kinesiotherapy was effective in this patient; tDCS sessions were safe and well-tolerated and may have played a role in improving functional tests. Further controlled studies involving a larger number of patients are needed to analyze the benefits of these combined techniques to maximize motor rehabilitation in this population.

Gait, posture and cognition in Parkinson's disease.

Gait disorders and postural instability are the leading causes of falls and disability in Parkinson's disease (PD). Cognition plays an important role in postural control and may interfere with gait and posture assessment and treatment. It is important to recognize gait, posture and balance dysfunctions by choosing proper assessment tools for PD. Patients at higher risk of falling must be referred for rehabilitation as early as possible, because antiparkinsonian drugs and surgery do not improve gait and posture in PD.

Distúrbios da marcha e perda de controle postural são as causas principais de queda e incapacidade na doença de Parkinson (DP). A alteração cognitiva desempenha um papel importante para a perda do controle postural e aumenta o risco de quedas; ela também interfere no cuidado e tratamento dos distúrbios da marcha. É importante reconhecer os transtornos da marcha, postura e equilíbrio escolhendo instrumentos de avaliação adequados para identificar os pacientes que tem maior risco de quedas e referi-los para reabilitação o mais precocemente possível, porque os medicamentos e a cirurgia não melhoram a marcha, nem a postura de pacientes com DP.

Effects of resistance training on postural control in Parkinson's disease: a randomized controlled trial / Efeitos de um treinamento de resistência muscular no controle postural em indivíduos com doença de Parkinson: um estudo aleatorizado controlado

ABSTRACT Background: Postural instability affects Parkinson's disease (PD) patients' postural control right from the early stages of the disease. The benefits of resistance training (RT) for balance and functional capacity have been described in the literature, but few studies have been conducted showing its effects on PD patients' postural control. Objective: To investigate the effects of a three-month RT intervention on static posturography (SP) measurements and clinical functional balance assessment among PD patients. Methods: Seventy-four patients were randomly assigned to a three-month RT intervention consisting of using weightlifting machines at a gym (gym group) or RT consisting of using free weights and elastic bands (freew group), or to a control group. The participants were evaluated at baseline, three months and six months. We evaluated changes of SP measurements under eyes-open, eyes-closed and dual-task conditions (primary endpoint), along with motor performance and balance effects by means of clinical scales, dynamic posturography and perceptions of quality of life (secondary endpoints). Results: There were no significant interactions in SP measurements among the groups. Unified Parkinson Disease Rating Scale (UPDRS-III) motor scores decreased in both RT groups (p<0.05). Better perceived quality of life for the mobility domain was reported in the gym group while functional balance scores improved in the freew group, which were maintained at the six-month follow-up (p<0.05). Conclusions: This study was not able to detect changes in SP measurements following a three-month RT intervention. Both RT groups of PD patients showed improved motor performance, with positive balance effects in the freew group and better perceived quality of life in the gym group.

RESUMO Introdução: A instabilidade postural afeta o controle postural desde os estágios iniciais da doença de Parkinson (DP). A literatura descreve benefícios do programa de fortalecimento muscular no equilíbrio, na capacidade funcional, porém poucos estudos investigaram seus efeitos no controle postural na DP. Objetivo: Investigar os efeitos de um programa de três meses de fortalecimento nas medidas da posturografia estática (PE) e nos testes clínicos na DP. Métodos: Participaram do ensaio aleatório controlado 74 pacientes, designados em um dos seguintes grupos: fortalecimento utilizando aparelhos de musculação (gmusc); fortalecimento com pesos livres e elásticos (gpeso); e grupo controle. As avaliações ocorreram antes da intervenção, 3 e 6 meses após intervenção. Foram avaliados alterações nas medidas da PE nas condições de olhos abertos, olhos fechados e dupla tarefa (desfecho primário), efeitos sobre sintomas motores, equilíbrio por meio de escalas clínicas, posturografia dinâmica e percepção da qualidade de vida (desfechos secundários). Resultados: Não houve interações significativas nas medidas da PE entre os grupos. As pontuações motoras da Escala Unificada de Avaliação da Doença de Parkinson (UPDRS-III) diminuíram em ambos os grupos de fortalecimento (p<0,05). Houve melhora da percepção da qualidade de vida para o domínio mobilidade no gmusc, assim como ganhos nas pontuações dos testes funcionais no gpeso, mantido no seguimento após seis meses (p<0,05). Conclusões: O programa de fortalecimento não altera o controle postural medida pela PE. Apesar disso, ambos os grupos de fortalecimento apresentaram melhor desempenho motor, efeitos positivos a médio prazo no equilíbrio no gpeso e melhor desempenho na qualidade de vida no gmusc.

The competition with a concurrent cognitive task affects posturographic measures in patients with Parkinson disease.

OBJECTIVES: To estimate the impact of a sensory-motor- cognitive task on postural balance, in Parkinson disease patients (Hoehn and Yahr 2-3) and to investigate possible relationships between posturography and functional balance clinical scales. METHOD: Parkinson disease patients (n = 40) and healthy controls (n = 27) were evaluated with fluency tests, Berg Balance scale, Mini Best test and static posturography on the conditions eyes open, eyes closed and dual-task (simultaneous balance and fluency tasks). RESULTS: Posturographic data showed that Parkinson disease patients performed worse than controls in all evaluations. In general, balance on dual-task was significantly poorer than balance with eyes closed. Posturographic data were weakly correlated to clinical balance scales. CONCLUSION: In clinical practice, Parkinson disease patients are commonly assessed with eyes closed, to sensitize balance. Our study showed that adding a cognitive task is even more effective. Static posturographic data should be carefully overgeneralized to infer functional balance impairments.

Schinus terebinthifolius Leaf Extract Causes Midgut Damage, Interfering with Survival and Development of Aedes aegypti Larvae.

In this study, a leaf extract from Schinus terebinthifolius was evaluated for effects on survival, development, and midgut of A. aegypti fourth instar larvae (L4), as well as for toxic effect on Artemia salina. Leaf extract was obtained using 0.15 M NaCl and evaluated for phytochemical composition and lectin activity. Early L4 larvae were incubated with the extract (0.3-1.35%, w/v) for 8 days, in presence or absence of food. Polymeric proanthocyanidins, hydrolysable tannins, heterosid and aglycone flavonoids, cinnamic acid derivatives, traces of steroids, and lectin activity were detected in the extract, which killed the larvae at an LC50 of 0.62% (unfed larvae) and 1.03% (fed larvae). Further, the larvae incubated with the extract reacted by eliminating the gut content. No larvae reached the pupal stage in treatments at concentrations between 0.5% and 1.35%, while in the control (fed larvae), 61.7% of individuals emerged as adults. The extract (1.0%) promoted intense disorganization of larval midgut epithelium, including deformation and hypertrophy of cells, disruption of microvilli, and vacuolization of cytoplasms, affecting digestive, enteroendocrine, regenerative, and proliferating cells. In addition, cells with fragmented DNA were observed. Separation of extract components by solid phase extraction revealed that cinnamic acid derivatives and flavonoids are involved in larvicidal effect of the extract, being the first most efficient in a short time after larvae treatment. The lectin present in the extract was isolated, but did not show deleterious effects on larvae. The extract and cinnamic acid derivatives were toxic to A. salina nauplii, while the flavonoids showed low toxicity. S. terebinthifolius leaf extract caused damage to the midgut of A. aegypti larvae, interfering with survival and development. The larvicidal effect of the extract can be attributed to cinnamic acid derivatives and flavonoids. The data obtained using A. salina indicates that caution should be used when employing this extract as a larvicidal agent.

Intervenções Grupais para Mulheres com Câncer de Mama: Desafios e Possibilidades / Group Interventions for Women with Breast Cancer: Challenges and Possibilities

Resumo Este estudo teve por objetivo analisar a produção científica nacional e internacional sobre os grupos de reabilitação psicossocial para mulheres com câncer de mama. O levantamento bibliográfico foi realizado a partir das bases indexadoras LILACS, PubMed, PsycINFO e CINAHL. Foram selecionados 28 artigos, publicados no período de 2000 a 2015, que constituíram o corpus do estudo. Os achados foram agrupados por meio de análise de conteúdo. Os resultados evidenciaram que os grupos de apoio podem resultar em benefícios psicossociais, como redução de estresse, incremento da qualidade de vida, melhora do humor e compartilhamento de informações sobre as diversas opções de tratamentos disponíveis. Conclui-se que participar de grupos de apoio está associado a melhores desfechos psicológicos, contudo, não há evidências que comprovem aumento na expectativa de vida das mulheres.

Abstract This study aimed to analyze the national and international scientific literature on the topic of psychosocial rehabilitation groups for women with breast cancer. The literature review was conducted from LILACS, PubMed, PsycINFO and CINAHL database. 28 articles published in the period 2000-2015, which constituted the corpus of the study, were selected. The results showed that, in most cases, support groups bring psychosocial benefits, stress reduction, increased and quality of life, mood enhancement and sharing information about different options of treatment available for breast cancer. We conclude that participating in support groups is associated with better psychological outcomes, however, there is no evidence to support an increase in life expectancy of women.

Listenmee and Listenmee smartphone application: synchronizing walking to rhythmic auditory cues to improve gait in Parkinson's disease.

Evidence supports the use of rhythmic external auditory signals to improve gait in PD patients (Arias & Cudeiro, 2008; Kenyon & Thaut, 2000; McIntosh, Rice & Thaut, 1994; McIntosh et al., 1997; Morris, Iansek, & Matyas, 1994; Thaut, McIntosh, & Rice, 1997; Suteerawattananon, Morris, Etnyre, Jankovic, & Protas , 2004; Willems, Nieuwboer, Chavert, & Desloovere, 2006). However, few prototypes are available for daily use, and to our knowledge, none utilize a smartphone application allowing individualized sounds and cadence. Therefore, we analyzed the effects on gait of Listenmee®, an intelligent glasses system with a portable auditory device, and present its smartphone application, the Listenmee app®, offering over 100 different sounds and an adjustable metronome to individualize the cueing rate as well as its smartwatch with accelerometer to detect magnitude and direction of the proper acceleration, track calorie count, sleep patterns, steps count and daily distances. The present study included patients with idiopathic PD presented gait disturbances including freezing. Auditory rhythmic cues were delivered through Listenmee®. Performance was analyzed in a motion and gait analysis laboratory. The results revealed significant improvements in gait performance over three major dependent variables: walking speed in 38.1%, cadence in 28.1% and stride length in 44.5%. Our findings suggest that auditory cueing through Listenmee® may significantly enhance gait performance. Further studies are needed to elucidate the potential role and maximize the benefits of these portable devices.

Is virtual reality beneficial for dual-task gait training in patients with Parkinson's disease? A systematic review / A realidade virtual é benéfica para o treino de marcha com tarefa dupla em pacientes com doença de parkinson? revisão sistemática

ABSTRACT This systematic review examined the evidence about the effects of virtual reality (VR) on dual-task gait training in Parkinson's disease (PD). Methods: this study (PROSPERO registration CRD42019114736) aimed to answer the question: "Is VR beneficial for dual-task gait training in patients with PD?" We searched for studies from 2008 to 2018 on Medline/PubMed and Web of Science/Web of knowledge databases. The keywords were Parkinson AND gait training AND virtual reality OR Parkinson AND gait training AND game. A total of 55 articles were retrieved, of which 11 systematic reviews, 11 opinions, letters to the editor, posters or conferences abstracts and 17 studies not evaluating the effects of VR gait training were excluded. Three further studies addressing VR dual-task gait training in PD (found in references of studies selected) were also included. Therefore, 19 studies were included and analysed. Results: all studies reported gait improvement after VR training. Many clinical scales were used, hampering comparison of the effects of each protocol. Conclusion: VR dual-task gait training should be part of rehabilitation protocols for PD. The studies showed that VR training was effective, although specific guidelines have not yet been established.

RESUMO Essa revisão sistemática examinou as evidências sobre os efeitos da realidade virtual (RV) no treinamento de marcha com tarefa-dupla na doença de Parkinson (DP). Métodos: esse estudo (registro PROSPERO: CRD42019114736) visou responder à questão: "A RV é benéfica no treinamento de marcha com tarefa-dupla em pacientes com DP?" A busca, de 2008 a 2018, foi feita nos bancos de dados Medline/PubMed e Web of Science/Web of Knowledge. Os descritores foram Parkinson, treinamento de marcha, realidade virtual e jogos eletrônicos. Foram encontrados 55 artigos e eliminadas 11 revisões sistemáticas, 11 cartas ao editor, resumos de pôsteres ou conferências e 17 estudos que não avaliaram os efeitos do treinamento da marcha em RV. Três outros estudos (encontrados nas referências dos estudos selecionados) foram incluídos porque também abordaram o treinamento de marcha com dupla tarefa de RV em DP. Portanto, 19 estudos foram incluídos e analisados. Resultados: todos os estudos relataram melhora da marcha após o treinamento com RV. Muitas escalas clínicas foram usadas e foi difícil comparar os efeitos de cada protocolo. Conclusão: RV deve fazer parte dos protocolos de reabilitação em DP. O treinamento com RV é eficaz, embora recomendações específicas ainda não tenham sido estabelecidas.
