Vocal Load of University Professors: Preliminary Results

Purpose: To describe the acoustic characteristics of a classroom, voice quality, fatigue, and vocal load of university professors. Methods: Exploratory, observational, longitudinal, and descriptive study with a single group of participants, including vocal monitoring data over two weeks. Acoustic characterization of the classroom, perceptual-auditory evaluation, and acoustic analysis of voice samples were conducted before and after classes. Vocal dosimetry was performed during classes, and the Vocal Fatigue Index (VFI) was assessed at the beginning of each week. Descriptive analysis of the findings was conducted, and randomization test was performed to verify the internal reliability of the judge. Results: All participants reported speaking loudly in the classroom, with the majority reporting vocal changes in the past six months, and only one participant reported a current vocal change. The classroom had acoustical measures and estimations that deviated from established standards. The professors used high vocal intensities during classes. After the classes, an increase in the absolute values of the aggregated data for CAPE-V, jitter, and fundamental frequency was found, varying within the range of normality. Furthermore, there was an observed increase in both post-lesson intensity and VFI when comparing the two-week period. Conclusions: Vocal intensities and VFI were possibly impacted by the acoustics of the classroom. The increase in average VFI between the weeks may be attributed to a cumulative fatigue sensation. Further research with a larger number of participants and in acoustically conditioned classrooms is suggested in order to evaluate collective intervention proposals aimed at reducing the vocal load on teachers.

Objetivo: Describir las características acústicas, calidad vocal, fatiga y carga vocal de profesores universitarios. Métodos: Estudio exploratorio, observacional, longitudinal, descriptivo con un solo grupo de participantes y datos de monitoreo vocal durante dos semanas. Se realizó caracterización acústica de la sala, evaluación auditiva-perceptiva y acústica de muestras de voz antes y después de las clases. Se realizó dosimetría vocal durante las clases y se verificó el Índice de Fatiga Vocal (IFV) en dos semanas. Se realizó un análisis descriptivo de los hallazgos y una prueba de aleatorización para verificar la confiabilidad interna del juez. Resultados: Todos los participantes informaron hablar en voz alta en clase, la mayoría informó cambios vocales en los últimos seis meses y solo uno informó cambios vocales actuales. La sala presentó mediciones y estimaciones acústicas fuera de las normas establecidas. Los profesores utilizaron intensidades vocales altas durante las clases. Hubo un aumento en los valores absolutos de los datos agrupados para CAPE-V, jitter y frecuencia fundamental, variando dentro de los límites normales, después de las clases. La intensidad después de las clases y el IFV, en la comparación entre las dos semanas, mostraron un aumento. Conclusiones: La dosis vocal y el IFV posiblemente se vieron afectados por la acústica del aula. El aumento del IFV medio entre semanas pudo deberse a la sensación de cansancio acumulada. Se sugieren nuevas investigaciones con un mayor número de participantes y que se realicen en la sala acondicionada acústicamente para evaluar propuestas de intervención colectiva, con el objetivo de reducir la carga vocal de los docentes.

Antagonistic activity of lactic acid bacteria isolated from Minas artisanal cheeses against Brucella abortus / Atividade antagonista de bactérias lácticas isoladas de queijos Minas artesanais contra Brucella abortus

This study aimed to evaluate methods for studying the in vitro antimicrobial activity of lactic acid bacteria (LAB) against Brucella abortus and to evaluate the antagonistic effect of LAB on the viability of this pathogen. A total of 18 LAB strains (Lactobacillus plantarum, n = 11; Pediococcus acidilactici, n = 1; Lactobacillus rhamnosus, n = 4; and Lactobacillus brevis,n = 2), isolated from Minas artisanal cheeses produced in three regions (Canastra, Campos das Vertentes, and Araxá) of Minas Gerais State, Brazil, were tested for their antimicrobial activity against B. abortus using three methods: spot-on-lawn, agar well diffusion assay, and antagonistic activity of the culture supernatants. None of the tested LAB strains could inhibit B. abortus in the spot-on-lawn and agar-well diffusion assays. The supernatants produced by LAB had an acidic pH, with intensity depending on bacterial growth and strain, and could inhibit the growth of B. abortus. In contrast, pH-neutralized (pH 7.0) LAB supernatants did not suppress the growth of B. abortus. The results showed that the best technique to study the in vitro antagonism of LAB against B. abortus was the antagonistic activity of culture supernatants. The growth of B. abortus may have been inhibited by acid production.(AU)

Este estudo teve como objetivo avaliar métodos de estudo in vitro da atividade antimicrobiana de bactérias lácticas contra Brucella abortus e avaliar o efeito antagônico das mesmas sobre a viabilidade deste patógeno. Um total de 18 amostras de bactérias lácteas (Lactobacillus plantarum, n = 11; Pediococcus acidilactici, n = 1; Lactobacillus rhamnosus, n = 4; e Lactobacillus brevis, n = 2), isoladas de exemplares de Queijo Minas Artesanal produzidos em três regiões (Canastra, Campos das Vertentes e Araxá) do estado de Minas Gerais, Brasil, foram testados quanto à sua atividade antimicrobiana contra B. abortus usando três métodos: spot-on-lawn, ensaio de difusão em poço e atividade antagonista de sobrenadante de cultura. Nenhuma das cepas testadas foi capaz de inibir B. abortus nos ensaios spot-on-lawm e de difusão em poço. Os sobrenadantes produzidos pelas bactérias lácteas apresentaram pH ácido, com intensidade dependente do crescimento bacteriano e da amostra, podendo inibir o crescimento de B. abortus. Em contraste, os sobrenadantes com pH neutralizado (pH 7,0) não inibiram o crescimento de B. abortus. Os resultados mostraram que a melhor técnica para estudar o antagonismo in vitro de bactérias lácteas contra B. abortus foi a atividade antagonista de sobrenadante de cultura. O crescimento de B. abortus pode ter sido inibido pela produção de ácido.(AU)

Efeito de uma intervenção remota de atividade física no risco cardiovascular e na aptidão física / The effects of a remote physical activity intervention on cardiovascular risk and physical fitness

RESUMO Devido à pandemia da COVID-19, os projetos de orientação de atividade física (AF) tiveram que adaptar suas atuações para o formato remoto. O objetivo deste estudo foi avaliar os efeitos de uma intervenção remota de AF no risco cardiovascular e na aptidão física em participantes desses projetos. Para isso, 29 participantes do Projeto Exercício e Coração (66±5 anos) foram orientados a realizar, 2 caminhadas, 1 videoaula de exercícios aeróbicos e 2 videoaulas de exercícios de força muscular por semana, sendo cada atividade realizada por 30 min e em intensidade moderada. No início e após 8 semanas, foram medidos marcadores de risco cardiovascular e de aptidão física, que foram comparados por testes t-student ou Wilcoxon, considerando-se p≤0,05. Comparando-se as avaliações pré e pós-intervenção, houve redução da circunferência da cintura (95,9±11,3 vs. 94,7±11,3 cm, p=0,013) e aumento da capacidade cardiorrespiratória (117±21 vs. 123±23 passos, p=0,019), da força dos membros superiores (23±6 vs. 25±6 repetições, p=0,003), da resistência abdominal (20±9 vs. 22±10 repetições, p=0,002) e da aptidão física geral (-0,04±3,55 vs. 1,30±4,10, p=0,000). Em conclusão, a intervenção remota aumentou a aptidão física geral, aumentando a capacidade cardiorrespiratória, a força e a resistência muscular, além de reduzir a obesidade central.

ABSTRACT Due to the COVID-19 pandemic, the projects that offer guidance for physical activity (PA) had to be adapted to the remote format. This study aimed at assessing the effects of a remote PA intervention on the cardiovascular risk and physical fitness of the individuals engaged in these projects. Thus, 29 participants of the Brazilian project known as Projeto Exercício e Coração (Exercise and Heart Project) (66±5 years) were instructed to perform 2 walking sessions, 1 aerobic exercise video class and 2 muscle strength video classes per week with each activity lasting 30 min and performed at moderate intensity. At baseline (pre) and after 8 weeks (post), markers of cardiovascular risk and physical fitness were evaluated and compared by using paired t-tests or Wilcoxon signed rank tests considering p≤0.05. When comparing pre- and post-intervention evaluations, there was a significant reduction in waist circumference (95.9±11.3 vs. 94.7±11.3 cm, p=0.013) and significant increases in cardiorespiratory fitness (117±21 vs. 123±23 steps, p=0.019), upper limb strength (23±6 vs. 25±6 repetitions, p=0.003), abdominal endurance (20±9 vs. 22±10 repetitions, p= 0.002) and overall physical fitness (-0.04±3.55 vs. 1.30±4.10, p=0.000). In conclusion, the remote intervention improved general physical fitness, increasing cardiorespiratory fitness, muscle strength and endurance, in addition to reducing central obesity.

Resistência das populações de Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae) aos inseticidas utilizados para o controle: estado da arte do conhecimento / Resistance of Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae) populations to insecticides used for control: art state of knowledge

Introdução: cerca de quatro bilhões de pessoas residem em áreas com risco de dengue, uma arbovirose transmitida pelo mosquito Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae). Na tentativa de combater esse vetor e reduzir a disseminação da dengue, o meio de controle vetorial frequentemente utilizado são os inseticidas. Entretanto, o uso indiscriminado destes no controle do mosquito está relacionado aos mecanismos de resistência desse vetor. Objetivo: mapear as evidências científicas relacionadas à resistência do mosquito A. aegypti aos inseticidas utilizados para o controle populacional. Metodologia: revisão de escopo, segundo metodologia Instituto Joana Briggs, em bases de dados indexadas: PubMed, Embase, CINAHL, Web of Science, SCOPUS e Biblioteca Virtual em Saúde. Através do mnemônico PCC (população, conceito e contexto), elaborou-se a estratégia de busca utilizando descritores do Decs e Mesh. Resultados: foram encontrados 1.631 estudos sobre a temática. Após critérios de elegibilidade e seleção, foram incluídos 30 estudos específicos sobre resistência do Aedes aegypti a inseticidas foram incluídos na revisão. A maior parte tratou de forma experimental e 28 (93,3%) estudos trabalharam o controle químico. Em relação à resistência a inseticidas, em 20 estudos (66,6%) constatou-se resistência metabólica e em 9 (30%) a resistência mediada pela alteração da variabilidade genética. Os estudos que observaram mutação não deixam claro se a mutação gênica é especificamente devido à ação mutagênica aos inseticidas. Conclusões:o A. aegypti desenvolve adaptações que lhe conferem resistência aos inseticidas, sendo que esses mecanismos de resistência estão relacionados à variabilidade genética e a adaptações metabólicas, que são transmitidas a seus descendentes ao longo das gerações. Assim, torna-se necessário um avanço nos estudos visando não apenas identificar e explicar os mecanismos de resistência, mas encontrar meios alternativos de manejo que possam controlar o inseto sem ocasionar resistência aos mesmos.

Introduction: about four billion people live in areas at risk of dengue, an arbovirus transmitted by the Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae). To combat this vector and reduce the spread of dengue, the means of vector control often used are insecticides. However, their indiscriminate use in mosquito control is related to the resistance mechanisms of this vector. Objective: to map the scientific evidence related to the resistance of the Aedes aegypti mosquito to the insecticides used to control dengue. Methodology: scope review, according to the Joana Briggs Institute methodology, in indexed databases: PubMed, Embase, CINAHL, Web of Science, SCOPUS and Virtual Health Library. Using the mnemonic PCC (population, concept and context), a search strategy was developed using Decs and Mesh descriptors. Results: 1,631 studies on the subject were found. After eligibility and selection criteria, 30 specific studies on Aedes aegypti resistance to insecticide were included in the review . Most treated experimentally and 28 (93.3%) studies worked on chemical control. Regarding the resistance to insecticide, in 20 studies (66.6%) there was found metabolic resistance and in 9 (30%) resistance mediated by modification on the genetic variability. Studies that have looked at mutation do not make it clear whether the gene mutation is specifically due to mutagenic action of insecticides. Conclusions: Aedes aegypti develops adaptations that gives them resistance to insecticides, and these resistance mechanisms are related to genetic variability and to metabolic adaptations, which are transmitted to its descendants over generations. Thus, it is necessary to perform advance in studies aiming not only to identify and explain the resistance mechanisms, but to find alternative means of management that can control the insect without causing resistance to them.

TGF-ß1 and CD68 immunoexpression in capsules formed by textured implants with and without mesh coverage: a study on female rats

Purpose: To evaluate fibrosis formation and number of macrophages in capsules formed around textured implants without and with mesh coverage. Methods: Fibrosis was analyzed through transforming growth factor-beta 1 (TGF-ß1) immunomarker expression and the number of macrophages through CD68 percentage of cells in magnified field. Sixty female Wistar rats were distributed into two groups of 30 rats (unmeshed and meshed). Each group was then subdivided into two subgroups for postoperative evaluation after 30 and 90 days. The p value was adjusted by Bonferroni lower than 0.012. Results: No difference was observed in fibrosis between meshed and unmeshed groups (30 days p = 0.436; 90 days p = 0.079) and from 30 to 90 days in the unmeshed group (p = 0.426). The meshed group showed higher fibrosis on the 90th day (p = 0.001). The number of macrophages was similar between groups without and with mesh coverage (30 days p = 0.218; 90 days p = 0.044), and similar between subgroups 30 and 90 days (unmeshed p = 0.085; meshed p = 0.059). Conclusions: In the meshed group, fibrosis formation was higher at 90 days and the mesh-covered implants produced capsules similar to microtextured ones when analyzing macrophages. Due to these characteristics, mesh coating did not seem to significantly affect the local fibrosis formation.

Measurement properties of the Brazilian online version of the Fibromyalgia Rapid Screening Tool (FiRST)

Abstract Objective The Fibromyalgia Rapid Screening Tool (FiRST) was developed to screen people with chronic pain for Fibromyalgia (FM), especially in primary health care settings. This study aimed to translate the FiRST into Brazilian Portuguese and evaluate its measurement properties for an online application. Methods After the process of translation and backtranslation, the FiRST was applied online in 483 adults with chronic pain (FM group n = 395; Chronic pain group n = 88), along with the Numerical Rating Scale for pain and fatigue, the Brief Pain Inventory, and the Fibromyalgia Impact Questionnaire-Revised. A Receiver Operating Characteristics (ROC) curve was computed and the area under the curve (AUC) was used to determine the sensibility, specificity, and cutoff score for the FiRST. The Mann-Whitney test was used for quantitative variables and the Chi-square and the Fisher's exact test, for the categorical variables with level of significance of 5%. Fleiss' Kappa, Gwet's AC1 and percentage of agreement were also calculated between test and retest. Results For all the questionnaires, the FM group presented higher scores, which mean a worst condition. The FiRST presented a sensitivity of 92.3%, and a specificity of 61.6% with 5 as the cut-off score. AUC, Fleiss' Kappa, Gwet's AC1 and percentage of agreement were, respectively, 0.82, 0.38, 0.63 and 71.8%. Conclusion The FiRST was translated into Brazilian Portuguese and the online version presented a good content validity and adequate measurement errors that allow FM patients to be screened among people with chronic pain.

In loco provision of physical therapy services to military firefighters involved in Brumadinho dam disaster

ABSTRACT Objective To investigate the impact of in loco physical therapy interventions on military firefighters involved in search and rescue operations following the collapse of the Brumadinho dam, in Minas Gerais. To describe the clinical and demographic profile of military firefighters receiving physical therapy care. Methods Physical therapy assessment and care protocols were designed. Protocols were based on manual physical therapy approaches, and aimed primarily to alleviate musculoskeletal pain. Physical therapists involved were duly trained prior to interventions to level technical skills. Physical therapy was provided upon request (i.e., military workers sought the service after work shift completion). Results A total of 318 military firefighters, most of whom were males (92.5%) mean age 32.9 years, received physical therapy care (575 sessions spread out over 48 days). In this sample, 43.4% of military workers had a history of musculoskeletal complaints. Military workers seeking physical therapy after completion of their work shifts reported mean pain intensity of 5.4 in a numerical scale. Spinal pain was reported in 61.7% of cases, followed by generalized muscle and myofascial pain (16.7%), lower and upper limb pain (14.4% and 6.8%, respectively). At the end of sessions, mean pain intensity reported dropped down to 1.3. Differences were statistically significant (non-parametric Wilcoxon test; p=0.001). Conclusion The unprecedented physical therapy intervention described had a positive impact on relief of musculoskeletal pain among military firefighters involved in search and rescue operations during the Brumadinho dam disaster, and seen at the end of their work shifts.

Este estudo qualitativo busca, a partir do Modelo Bioecológico do Desenvolvimento Humano de Bronfenbrenner, compreender como as características psicossociais influenciam na empregabilidade e na expectativa de futuro dos jovens. Para a coleta de dados, foram realizados dois grupos focais e doze entrevistas individuais com os jovens que vivem em situação de vulnerabilidade social, além de quatro entrevistas com profissionais que interagem com os jovens na instituição que participa do Programa Jovem Aprendiz. A partir da técnica de análise de conteúdo, foi possível compreender a influência negativa da adaptabilidade de carreira, da identidade de carreira e do capital humano e social na empregabilidade dos jovens. No âmbito dos fatores físicos, econômicos e sociais, a baixa renda, as condições de moradia e o bem-estar social são fatores determinantes no baixo desenvolvimento dos jovens, além de impactar negativamente nas expectativas educacionais e profissionais.

Based on Bronfenbrenner's Bioecological Model of Human Development, this qualitative study aims to understand how psychosocial characteristics influence young people's employability and future expectations. For data collection, two focus groups and twelve individual interviews were carried out with young people who live in a situation of social vulnerability, in addition to four interviews with professionals who interact with young people in the institution that participates in the Young Apprentice program. From the content analysis technique, it was possible to understand the negative influence of career adaptability, career identity, and human and social capital on the employability of young people. In terms of physical, economic, and social factors; low income, housing conditions, and social well-being are determining factors in the low development of young people, in addition to negatively impacting educational and professional expectations.

Basado en el Modelo Bioecológico de Desarrollo Humano de Bronfenbrenner, este estudio cualitativo tiene como objetivo comprender cómo las características psicosociales influyen en la empleabilidad y en las expectativas de futuro de los jóvenes. Para la recolección de datos se realizaron dos grupos focales y doce entrevistas individuales con jóvenes que viven en situación de vulnerabilidad social, además de cuatro entrevistas a profesionales que interactúan con jóvenes en la institución que participa en el Programa Jovem Aprendiz. A partir de la técnica de análisis de contenido, se pudo comprender la influencia negativa de la adaptabilidad profesional, de la identidad profesional y del capital humano y social en la empleabilidad de los jóvenes. En el ámbito de los factores físicos, económicos y sociales, los bajos ingresos, las condiciones de vivienda y el bienestar social son factores determinantes en el bajo desarrollo de los jóvenes, además de impactar negativamente en las expectativas educativas y profesionales.

Reproducibility of the classification of proximal humeral ossification in idiopathic scoliosis / Reprodutibilidade da classificação da ossificação do úmero proximal na escoliose idiopática / Reproducibilidad de la clasificación de la osificación del húmero proximal en la escoliosis idiopática

ABSTRACT Objective To evaluate the intra- and interobserver reproducibility of the classification of proximal humeral ossification in patients with idiopathic scoliosis. Methods Observational, descriptive, cross-sectional study. Radiographs (anteroposterior) of 29 patients diagnosed with idiopathic scoliosis were chosen and investigated at the Spine Surgery Outpatient Clinic of the Department of Orthopedics and Traumatology of the Hospital Getúlio Vargas, Recife, Pernambuco. These radiographs were evaluated and classified by 9 spinal orthopedic surgeons at two moments, with a minimum interval of 30 days, for analysis of the intraobserver and interobserver reproducibility of the classification of proximal humeral ossification used as a predictor of peak growth velocity. Results Intraobserver reproducibility achieved moderate to substantial concordance with the kappa index. In the analysis of interobserver reproducibility using the Fleiss' kappa method, a reasonable to moderate concordance was observed, except for in stage 5, in which concordance ranged from substantial to almost perfect. Conclusion In this study, the reproducibility of the Li classification in most of the stages was reasonable to moderate for the interobserver assessment and moderate to substantial for the intraobserver assessment, which differs from the current literature. Level of evidence III; Diagnostic studies - Investigation of a diagnostic test.

Extensa lesão cutânea tardia por exposição à radiação ionizante de fluoroscopia: relato de caso / Extensive late skin lesion due to fluoroscopy ionizing radiation exposure: a case report

RESUMO A reação cutânea induzida por radiação (RCIR) é geralmente caracterizada por edema, hiperemia, fibrose, ulceração, dor e prurido na pele. Sabe-se que a radiação interrompe o processo normal de divisão e regeneração celular, resultando em dano que pode envolver prejuízo na função das células endoteliais, inflamação e até morte celular. A recuperação do dano tecidual pela radiação depende de múltiplos fatores relativos ao procedimento realizado e também intrínsecos ao paciente. Apresentamos caso atípico de RCIR, cujas lesões apresentaram comportamento muito imprevisível e de difícil manejo clínico. Além disso, ressalta-se a importância da intervenção cirúrgica neste caso, fundamental para o tratamento adequado do paciente.

Histological evaluation of capsules formed by texturized silicone implants with and without polyester mesh coverage (Parietex®). A study on female rats

ABSTRACT Purpose To evaluate capsules formed by microtextured silicone implants with and without Parietex® mesh coverage histologically. Methods Sixty Wistar rats were divided in two groups (meshed and unmeshed). Each group was, then, divided into two subgroups for evaluation at 30 and 90 days. Capsules were analyzed based on hematoxylin and eosin (HE) and picrosirius staining. Results The number of fibroblasts, neutrophils and macrophages was similar among all subgroups. There was a higher lymphocyte reaction in the 30-day meshed group (p = 0.003). Giant cell reaction, granulation tissue and neoangiogenesis were similar among the subgroups. Synovial metaplasia was milder at 90-day in the unmeshed (p = 0.002) and meshed group (p < 0.001). Capsular thickness was significantly greater in the meshed samples (30-day p < 0.001 and 90-day p < 0.001). There was a similar amount of collagen types I and III in both groups. Conclusions The mesh-covered implants produced capsules similar to the microtextured ones when analyzing inflammatory variables. Synovial metaplasia was milder at 90 than at 30 days, and the capsular thickness was significantly greater in the meshed group. A similar amount of collagen types I and III was observed. Due to these characteristics, the mesh coverage did not seem to significantly affect the local inflammatory activity.

Platelet-concentrated and platelet poor-plasma promote different pattern on immunohistochemical expression of TGF-β1, however they impairs the osteoneogensis in calvarial defects treated with autograft due suppression of osteocalcin

ABSTRACT Purpose Herein we evaluated the effects of platelet concentrate (PC) and platelet-poor plasma (PPP) on bone repair using noncritical defects in the calvaria of rabbits and compared them to the presence of TGF-β1 and osteocalcin on reparative sites. Methods Five noncritical defects of 8.7 mm in diameter were created on the calvaria of 15 animals. Each defect was treated differently, using autograft (ABG), ABG associated with PC (ABG + PC), ABG with PPP (ABG + PPP), isolated PPP, and blood clot (control). The animals were submitted to euthanasia on the second, fourth and sixth week post-surgery. Results The defects that received ABG+PC or PPP demonstrated lower bone formation when compared to specimens that received ABG in the same period. These results coincided to significant higher immunopositivity for TGF-β1 for specimens that received PC, and lower presence of cytokine in the group PPP. However, either higher or lower presence of TGF-β1 were also correlated to lower presence of osteocalcin. Likewise, these results were similar to findings in specimens treated only with PPP when compared to control. Conclusions PC and PPP were not effective when applied in association with ABG. Similarly, isolated use of PPP was not beneficial in optimizing the bone repair.

Depression, anxiety and kinesiophobia in women with fibromyalgia practitioners or not of dance / Depressão, ansiedade e cinesiofobia em mulheres com fibromialgia praticantes ou não de dança

ABSTRACT BACKGROUND AND OBJECTIVES: Fibromyalgia is defined as a chronic and diffuse pain syndrome, with greater prevalence in women aged 40 to 55 years and affects 2 to 4% of the world population, causing physical and psychological symptoms that decreases the quality of life of those affected. The aim of this study was to evaluate the symptoms of depression, anxiety and kinesiophobia in women with fibromyalgia who practice dance. METHODS: A cross-sectional study, with a quantitative approach, in which 40 women with fibromyalgia were evaluated, 20 of whom were dance practitioners (dance group - DG) and 20 who were non practitioners (non-dance group - NDG). All women responded to the Beck Depression Inventory, the Beck Anxiety Scale and the Tampa Kinesiophobia Scale. RESULTS: The average depression scores were considered mild for the dance group and moderate for the non-dance group. Anxiety was considered moderate in dance group and severe for non-dance group. Regarding kinesiophobia, both groups had a moderate degree, despite having differences in their scores. The dance group obtained significantly lower results than the non-dance group for all independent variables in this study. CONCLUSION: The symptoms of depression, anxiety and kinesiophobia showed higher values in the group of fibromyalgia patients who did not practice dance. Thus, dance practice seems to be associated with lesser presence of symptoms such as depression, anxiety and kinesiophobia in women with fibromyalgia.

RESUMO JUSTIFICATIVA E OBJETIVOS: A fibromialgia é definida como uma síndrome de dor crônica e difusa, com maior prevalência em mulheres de 40 a 55 anos de idade, acometendo de 2 a 4% da população mundial e causando sintomas físicos e psicológicos que diminuem a qualidade de vida dos afetados. O objetivo deste estudo foi avaliar os sintomas de depressão, ansiedade e cinesiofobia em mulheres com fibromialgia que praticam dança. MÉTODOS: Trata-se de um estudo transversal, com abordagem quantitativa, em que foram avaliadas 40 mulheres com fibromialgia, sendo 20 praticantes de dança (grupo dança - GD) e 20 que não realizavam essa prática (grupo não dança - GND). Todas as mulheres responderam ao Beck Depression Inventory, à Beck Anxiety Scale e à Tampa Kinesiophobia Scale. RESULTADOS: A média dos escores de depressão foi considerada leve para o grupo dança e moderada para o grupo não dança. A ansiedade foi considerada moderada no grupo dança e grave para o grupo não dança. No que diz respeito à cinesiofobia ambos os grupos apresentaram grau moderado, apesar de apresentar diferenças nos seus escores. O grupo dança obteve resultados menores do que o grupo não dança para todas as variáveis independentes desse estudo, de forma significativa. CONCLUSÃO: Os sintomas de depressão, ansiedade e cinesiofobia apresentaram maiores valores no grupo de fibromiálgicas que não praticavam dança. Desta forma, a prática de dança parece estar associada a menor presença de sintomas como depressão, ansiedade e cinesiofobia em mulheres com fibromialgia.

Pain education to women with fibromyalgia using the DolorÔmetro game / Educação em dor de mulheres portadoras de fibromialgia com o jogo DolorÔmetro

ABSTRACT BACKGROUND AND OBJECTIVES: Doubts and questions about the general aspects of pain, maladaptive beliefs, knowledge about pain neurophysiology, and its impact on exercise are common in fibromyalgia patients. This study aimed to evaluate the knowledge about pain in women with fibromyalgia through the DolorÔmetro game. METHODS: A quasi-experimental study with a qualitative and quantitative approach. Twenty women with a clinical diagnosis of fibromyalgia and aged 18 to 60 years were evaluated. The patients answered two questions at the beginning and end of the game. The intervention consisted of the use of 9 cards from the six domains of the game DolorÔmetro to motivate discussions about the theme. RESULTS: The sample had a mean age of 50.6±9.6 years and a diagnostic time of 6.5±4.6 years. The number of hits and errors in each domain was observed. In the "acceptance" domain, four errors were found in statement 1 and twelve in statement 2. In the "attitudes" domain, only two in statement 4 and one in statement 8. In the "kinesiophobia" domain, all errors were only in statement 2. In the "knowledge" domain, nineteen women missed statement 3. In the "anxiety" domain, fifteen women missed statement 1. Finally, in the "catastrophic" domain, ten women missed statement 2. CONCLUSION: Conducting an education in pain, lasting in one hour in a single moment, contributed to the participants expressing their doubts and previous questions and after the moment of education, however doubts persisted in the domains of acceptance, kinesiophobia, knowledge and anxiety.

RESUMO JUSTIFICATIVA E OBJETIVOS: As dúvidas e questionamentos sobre os aspectos gerais da dor, crenças mal adaptativas, conhecimento sobre neurofisiologia da dor e seu impacto na realização de exercícios são comuns nas pacientes com fibromialgia. O objetivo deste estudo foi avaliar o conhecimento sobre dor em mulheres com fibromialgia, por meio do jogo DolorÔmetro. MÉTODOS: Estudo quase-experimental com abordagem quali-quantitativa. Foram avaliadas 20 mulheres com diagnóstico clínico de fibromialgia com idade de 18 a 60 anos. As pacientes responderam duas perguntas no momento inicial e final do jogo. A intervenção consistiu no uso de 9 cartas a partir dos 6 domínios aceitação, atitudes, cinesiofobia, conhecimento, ansiedade e catastrofismo, do jogo DolorÔmetro para motivar as discussões sobre a temática. RESULTADOS: A média de idade foi 50,6±9,6 anos e o tempo diagnóstico de 6,5±4,6 anos. Foi avaliado o número de acertos e erros de cada domínio. No domínio "aceitação" foram 4 erros na afirmação 1 e 12 erros na afirmação 2. No domínio "atitudes", 2 na afirmação 4 e 1 na afirmação 8. No domínio "cinesiofobia", nenhum acerto na afirmação 2.

Radiographical analysis of flexibility of idiopatic scoliosis in prono and supino / Análise radiográfica da flexibilidade da escoliose idiopática em prono e supino / Análisis radiográfico de la flexibilidad de la escoliosis idiopática en prono y supino

ABSTRACT Objective To determine if there is a statistically significant difference in the flexibility of the curves in the adolescent idiopathic scoliosis (AIS) by using lateral inclination radiographs in supine or prone decubitus. Methods We evaluated 19 patients with AIS, waiting for surgery. Radiographs of the patients were performed in orthostatic anteroposterior incidences and right and left lateral inclinations in prone and supine decubitus. The comparison between prone and supine decubitus was performed through the flexibility rates of the curves measured in each position. Results The mean flexibility rates measured in lateral inclination radiographs with the patient in the supine position were 54.4% ± 38.8% in the proximal thoracic curve, 45.8% ± 15.6% in the main thoracic curve, and 80.5% ± 20.7% in the thoracolumbar / lumbar curve. When the lateral inclination radiographs were performed with the patient in the prone position, we observed mean flexibility rates of 66.4% ± 34.3% in the proximal thoracic curve, 50.1% ± 12.8% in the main thoracic curve, and 80.6% ± 19.0% in the thoracolumbar / lumbar curve. Conclusion This present study did not find a statistically significant difference between the flexibility rates of the curves in the prone and supine positions, suggesting that the two radiographic methods analyzed are similar in the evaluation of the flexibility of the curves in adolescent idiopathic scoliosis. Level of evidence II; Development of diagnostic criteria in consecutive patients (with "gold" reference standard applied).

RESUMO Objetivo Determinar se há diferença estatisticamente significativa na flexibilidade das curvas na escoliose idiopática do adolescente (EIA), ao utilizar radiografias em inclinação lateral em decúbito supino ou prono. Métodos Foram avaliados 19 pacientes com EIA, em espera de cirurgia. Os pacientes realizaram radiografias em incidências anteroposterior em ortostase, inclinações laterais direita e esquerda em decúbito prono e supino. Realizou-se a comparação entre o decúbito prono e supino através das taxas de flexibilidade das curvas aferidas em cada posição. Resultados A taxa de flexibilidade média aferida, quando realizadas as inclinações laterais com o paciente em posição supino, foi de 54,4% ± 38,8% na curva torácica proximal, 45,8% ± 15,6% na curva torácica principal e 80,5% ± 20,7% na curva toracolombar/lombar. Quando realizadas as inclinações laterais com o paciente em posição prono, observou-se taxa de flexibilidade média de 66,4% ± 34,3% na curva torácica proximal, 50,1% ± 12,8% na curva torácica principal e 80,6% ± 19,0% na curva toracolombar/lombar. Conclusão O presente estudo não encontrou diferença com significância estatística nas taxas de flexibilidade das curvas nas posições prono e supino, sugerindo que os dois métodos radiográficos analisados são semelhantes na avaliação da flexibilidade das curvas na escoliose idiopática do adolescente. Nível de evidência II; Desenvolvimento de critérios diagnósticos em pacientes consecutivos (com padrão de referência "ouro" aplicado).

Mat Pilates is as effective as aquatic aerobic exercise in treating women with fibromyalgia: a clinical, randomized and blind trial

Abstract Background: The mat Pilates method is the therapeutic modalities which can be used in fibromyalgia treatment. Although there are no well-designed studies that prove the effectiveness of the mat Pilates method in this population. The objective was to evaluate the effectiveness of the mat Pilates method for improving symptoms in women with fibromyalgia. Methods: A single blind randomized controlled trial in which 42 women with fibromyalgia were randomized into two groups: mat Pilates and aquatic aerobic exercise. The exercises were performed twice a week for 12 weeks. Two evaluations were performed: one at baseline (T0), and another at 12 weeks after randomization (T12). The primary outcome was pain measured by the Visual Analogue Scale (VAS). Secondary outcomes were function (Fibromyalgia Impact Questionnaire), sleep (Pittsburgh Sleep Quality Index [PSQI]), quality of life (Short Form 36 [SF-36]), fear avoidance (Fear Avoidance Beliefs Questionnaire [FABQ-BR]) and pain catastrophizing (Pain-Related Catastrophizing Thoughts Scale [PRCTS]). Results: There was improvement in both groups in relation to pain and function (p < 0.05). The aspects related to quality of life and the FABQ questionnaire only showed improvement in the mat Pilates group (p < 0.05). There was improvement in the PSQI and PRCTS variables only in the aquatic aerobic exercise group (p < 0.05), but no differences were observed between the groups for any of the evaluated variables. Conclusion: Significant improvements were observed in the two groups in relation to the disease symptoms, and no differences were observed between mat Pilates and aquatic aerobic exercise in any of the measured variables.

Clinical and self-perceived oral health assessment of elderly residents in urban, rural, and institutionalized communities

OBJECTIVES: This study aims to evaluate the self-perception of oral health according to the physical, psychosocial and pain/discomfort dimensions related to clinical conditions and orofacial pain of elderly people living in three different environments. METHODS: This was an observational, cross-sectional, quantitative study with a population-based approach and nonprobabilistic convenience sampling that included 81 elderly people: 27 resided in institutional homes for elderly individuals, 27 resided in an urban area and 27 resided in a rural area in the interior of Paraíba (PB) in northeastern Brazil. RESULTS: The Geriatric Oral Health Assessment Index (GOHAI) was used to assess self-perception of oral health, while the Questionnaire for Screening of Patients with Temporomandibular Disorders (QST/TMD) was used to assess the influences of orofacial pain and the biofilm indexes of teeth and prostheses. There was a statistically significant difference in the GOHAI scores among the places of residence, with the worst values associated with the rural area. According to the QST/TMD, the majority of individuals were affected by TMDs, with statistical differences for both sex and income. CONCLUSION: The biofilm analysis showed a higher incidence of clinical conditions in the rural population. The place of residence also influenced self-perception and the clinical oral health condition of elderly people; the rural population presented the worst results.
