Brazilian Portuguese version of the Patient Scar Assessment Questionnaire / Validação da versão em português do Patient Scar Assessment Questionnaire

Introduction: Scars and their associated signs and symptoms have the potential to impact many aspects of health. Given the growing number of individuals with new scars, it is essential to have reliable, sensitive, and specific assessment tools that analyze the influence that scars can have on the quality of life. The objective is translate the Patient Scar Assessment Questionnaire (PSAQ) into Portuguese, adapt it to the Brazilian cultural context, and test its reproducibility, reliability, and validity. Methods: The questionnaire was applied to 121 individuals with post-surgical scars consecutively selected at a plastic surgery clinic from January 2015 to June 2016. The PSAQ consists of 39 questions divided into five subscales: appearance, symptoms, perception, satisfaction with appearance, and symptoms. Then its reproducibility, face, content, and construct validity were analyzed. Internal consistency was tested using Cronbach's alpha coefficient, and construct validation was performed by correlating the translated instrument with the QualiFibro and Patient and Observer Scar Assessment Scale (POSAS) questionnaires. Results: Analysis of the internal consistency of the PSAQ subscales obtained values >0.70 in all domains, showing good internal consistency. Reproducibility was demonstrated using Pearson's correlation and the Bland-Altman method, and the outcomes showed good reproducibility. In construct validation, a significant correlation was observed in all PSAQ domains with POSAS and QualiFibro. Conclusion: The PSAQ was translated into Portuguese and adapted to Brazilian culture, reproducible and presenting face, content, and construct validity.

Medidas da região mamária: antropometria direta ou indireta? / Breast region measurements: direct or indirect anthropometry?

Introdução: As medidas precisas dos seios femininos são difíceis de obter devido à topografia, volume e projeções presentes. Portanto, este estudo teve como objetivo comparar medidas da região mamária obtidas por antropometria direta (fita métrica) e indireta (fotogrametria computadorizada). Métodos: Este é um estudo transversal. Foram avaliadas 40 mulheres, com idades entre 18 e 60 anos, índice de massa corporal <29,2 kg / m², que tinham 12 marcas anatômicas na região das mamas e braços. A união desses pontos formou 7 segmentos lineares e 1 ângulo para cada hemicorpo, e 1 segmento comum a ambos os hemicorpos. As fotografias obtidas de forma padronizada foram mensuradas por fotogrametria computadorizada com o software Image Tool®. Os mesmos segmentos também foram medidos por antropometria direta, com fita métrica. O teste de Shapiro-Wilk foi usado para avaliar se cada variável tinha uma distribuição normal. O teste de correlação de Pearson foi aplicado para avaliar a correlação entre os diferentes métodos: antropometria direta (medição com fita) e indireta (fotogrametria por Image Tool®). O nível de significância adotado para os testes estatísticos foi de 5% (p <0,05). Resultados: Diferenças significativas foram encontradas nas comparações entre a fita métrica e a fotogrametria computadorizada para todos os segmentos analisados (p> 0,05). Conclusão: Existe correlação entre as medidas dos seios da face obtidas pela antropometria direta (medição com fita métrica) e indireta (fotogrametria pelo software Image Tool®), principalmente nas medidas da papila.

Introduction: Accurate female breast measurements are difficult due to the topography, volume, and projections present there. Therefore, this study aimed to compare breast region measurements obtained by direct (tape measurement) and indirect (computer-based photogrammetry) anthropometry. Methods: This is a transversal study. Forty women were evaluated, aged 18-60 years, body mass index of <29.2kg/m² that had 12 anatomical marks on the breast region and arms. These points' union formed 7 linear segments and 1 angle for each hemibody, and 1 segment common to both hemibodies. The photographs obtained in a standardized way were measured using computer-based photogrammetry with Image ToolTM software. The same segments were also measured by direct anthropometry, using a tape measure. The Shapiro-Wilk test was used to assess whether each variable was normally distributed. The Pearson correlation test was applied to evaluate the correlation between different methods: the direct (tape measurement) and indirect (photogrammetry by Image ToolTM) anthropometry. The significance level adopted for statistical tests was 5% (p<0,05). Results: Significant differences were found in the comparisons between the tape measurement and computer-based photogrammetry for all segments analyzed (p>0.05). Conclusion: There is a correlation between the breast measurements obtained by direct (tape measurement) and indirect (photogrammetry by Image ToolTM software) anthropometry, especially the papilla measures.

JPEG and raw image files compared to direct measurement of the breast region

Abstract Purpose: To compare JPEG and RAW image file extensions to direct measurement of the breast region. Methods: Points were marked on the breasts and arms of 40 female volunteers. The joining of these points in each hemibody formed seven linear segments, one angular segment and one median segment common to both hemibodies. Volunteers were photographed in a standardized fashion and evaluated by three raters using the software Adobe Photoshop CS6® and three image file extensions (RAW, high resolution JPEG and low resolution JPEG); values were compared to direct anthropometry. Results: All variables had interclass correlation coefficient higher than 0.8 (ICC>0.8). On average, all variables in all methods showed differences (p<0.05) when compared to direct measurement. A formula was created for each segment and each image file extension in comparison with the direct measurement. Conclusion: Measurements were similar among the correlated JPEG and RAW image file extensions but differed from the actual breast measurement obtained with a caliper.

Heart rate variability based on risk stratification for type 2 diabetes mellitus / Variabilidade da frequência cardíaca com base na estratificação de risco para diabetes mellitus tipo 2

ABSTRACT Objective To evaluate heart rate variability among adults with different risk levels for type 2 diabetes mellitus. Methods The risk for type 2 diabetes mellitus was assessed in 130 participants (89 females) based on the questionnaire Finnish Diabetes Risk Score and was classified as low risk (n=26), slightly elevated risk (n=41), moderate risk (n=27) and high risk (n=32). To measure heart rate variability, a heart-rate monitor Polar S810i® was employed to obtain RR series for each individual, at rest, for 5 minutes, followed by analysis of linear and nonlinear indexes. Results The groups at higher risk of type 2 diabetes mellitus had significantly lower linear and nonlinear heart rate variability indexes. Conclusion The individuals at high risk for type 2 diabetes mellitus have lower heart rate variability.

Os participantes foram classificados em baixo risco (n=26), risco levemente elevado (n=41), risco moderado (n=27) e alto risco (n=32). Para medir a variabilidade da frequência cardíaca, utilizou-se o frequencímetro Polar S810i® para obter séries de intervalo RR para cada indivíduo, em repouso, durante 5 minutos; posteriormente, realizou-se análise por meio de índices lineares e não-lineares. Resultados O grupo com maior risco para diabetes mellitus tipo 2 teve uma diminuição significante nos índices lineares e não-lineares da variabilidade da frequência cardíaca. Conclusão Os resultados apontam que indivíduos com risco alto para diabetes mellitus tipo 2 tem menor variabilidade da frequência cardíaca.

Ground reaction force patterns during gait in patients with lower limb lymphedema / Forças de reação ao solo durante a marcha de pacientes com linfedema de membro inferior

Although gait problems have been reported in patients with lower limb lymphedema (LLL), the gait pattern (GP) changes have not been documented yet. However, it is possible that patients with LLL show abnormal GP that can be related to biomechanical complications related to osteoarthritis or falls affecting the quality of life. Ground reaction force analysis during gait allows objective assessment of the patients and it can be used to plan a rehabilitation approach. Objective: To analyze the GRF during gait in patients LLL. Methods: An experimental descriptive study was realized with twenty-three LLL patients, both unilateral and bilateral and classified as moderate and severe, participated in the experiments. The patients walked on a force plate while the three ground reaction force (GRF) components, vertical, mediolateral (M-L) and anteroposterior (A-P), under their feet were recorded and analyzed. Results: In the patients with unilateral lymphedema, either moderate or severe, the vertical GRF components of the affected limb were similar to the sound one and also resembling those found in healthy adults. The M-L GRF was smaller in the non-affected side. In patients with bilateral lymphedema gait speed was significantly slower. More interestingly, the vertical GRF pattern was flat, not showing the typical 2-peak shape. Finally, the large M-L forces found suggest gait stability problems. Conclusions: The patients showed abnormal GRF patterns, including compensation with the non-affected leg. The GRF variability was higher in the patients with severe unilateral lymphedema. Bilateral lymphedema results in lower A-P forces. Stance phase duration was longer in patients with bilateral and severe lymphedema

Low-dose resveratrol supplementation on heart rate variability in hypertensive volunteers: a controlled double-blind trial / Suplementação de baixa dose de resveratrol na variabilidade da frequência cardíaca em hipertensos: ensaio clinico controlado e duplo cego

OBJECTIVE: Hypertension decreases the heart rate variability (HRV). Resveratrol, a phenolic compound found in grapes and their products, has been explored for its potential to treat hypertension. We evaluated the effects of low-dose resveratrol on HRV in hypertensive volunteers. METHOD: Twenty-one hypertensive volunteers of both sexes were supplemented with resveratrol (n = 11) or placebo (n = 10) for 30 days. HRV parameters were measured before and during a standardized treadmill exercise. One resveratrol- and 3 placebo-treated patients were lost to follow-up. RESULTS: There were no anthropometric differences between resveratrol (n = 10) and placebo (n = 7) other than a difference in body mass index. The measured HRV parameters did not differ between resveratrol and placebo, or between control and treadmill exercise. CONCLUSION: Low-dose resveratrol did not alter HRV in hypertensive patients.

OBJETIVO: A hipertensão arterial diminui a variabilidade da frequência cardíaca (VFC). Resveratrol têm sido estudado como tendo potencial para o tratamento da hipertensão. Foram avaliados os efeitos de baixas doses de resveratrol na variabilidade da frequência cardíaca em voluntários hipertensos. MÉTODO: Vinte e um voluntários hipertensos, de ambos os sexos foram suplementados com resveratrol (n = 11) ou placebo (n = 10) durante 30 dias. Parâmetros da VFC foram medidos antes e durante o exercício em esteira padronizado. Um paciente tratado com resveratrol e três tratados com placebo foram perdidos. RESULTADOS: Não houve diferenças antropométricas entre os integrantes dos grupos resveratrol (n = 10) vs. placebo (n = 7), exceto uma diferença de índice de massa corporal. Não foram observadas diferenças para nenhum dos parâmetros da VFC entre resveratrol vs. placebo, ou entre controle vs. exercício em esteira. CONCLUSÃO: A baixa dose de resveratrol não afetou a VFC em hipertensos.

Quais Fatores Influenciam a Taxa de Aprovação na Disciplina de Anatomia Humana? / What Factors Influence the Approval Ratings in the Discipline of Human Anatomy?

RESUMO A Anatomia Humana (AH) é uma disciplina básica para todos os estudantes dos cursos superiores das áreas da saúde e biológica. A maior parte a considera de conteúdo difícil. O ensino da AH precisa ser repensado no contexto da política atual de acesso amplo ao ensino superior. E corresponder ao dever das instituições de proporcionar ao estudante uma formação de qualidade com vistas à formação de um profissional crítico e de perfil criativo frente às distintas situações do cotidiano. É preciso entender possíveis fatores que levam às elevadas taxas de reprovação nesta disciplina. Portanto, o objetivo do presente estudo foi relacionar o resultado do vestibular/Enem com hábitos de estudo e desejo profissional no desempenho acadêmico da disciplina dos alunos dos cursos de Educação Física, Ciências Biológicas e Nutrição do IF Sudeste MG. Foram entrevistados 129 alunos. A pontuação do vestibular/Enem foi maior entre os aprovados em AH; não houve entre os grupos diferença quantitativa nas horas de estudo e tampouco na escolha do curso, que ocorreu por opção do aluno (versus por falta de opção).

ABSTRACT Human Anatomy (HA) is a basic discipline in health and biological sciences indispensable to all academic students. Most of them consider its content very difficult. The teaching of HA needs to be rethought in the context of the current policy, which provides increasing access to higher education. It needs to be compatible with the institutions’ ability to meet their obligations and therefore, provide the student with a qualityeducation aimed at the formation of critical thinking and a creative profile to deal with different situations of everyday life. One must understand the potential factors that lead to high failure rates in this discipline. Therefore, the present study aimed to correlate the results of the entrance examination/ENEM with study habits and professional goals of the students’ academic performance in Physical Education, Biological Sciences and Nutrition courses of the IF Sudeste MG University. A total of 129 students were interviewed. The entrance examination or ENEM score was higher among those who passed in HA; there was no quantitative difference between the groups either in study hours or in the choice of course made by the student.

Photographs for anthropometric measurements of the breast region. Are there limitations?

PURPOSE: To determine the limitations of the photographs used to obtain the anthropometric measurements of the breast region. METHODS: Five women, between the ages of 18 to 60 years, were evaluated. Photographs of the frontal and left and right profile views of their breasts were taken. Based on the current literature, the most commonly used anthropometric and anatomic landmarks for breast measurement were marked in their different positions. The different points were used to evaluate if the direct anthropometry was possible in a standardized way and determine how the points and the positions can to be used in any breast measurements. RESULTS: There were some limitations to the use of defining points of the breast fold, as well as of its lower portion and lateral extension positions in both profiles. CONCLUSION: The defining points of the breast fold and the profile photographs have some limitations and we suggested how the points and positions can be used for breasts measurements. .

Image analysis software versus direct anthropometry for breast measurements

PURPOSE: To compare breast measurements performed using the software packages ImageTool(r), AutoCAD(r) and Adobe Photoshop(r) with direct anthropometric measurements. METHODS: Points were marked on the breasts and arms of 40 volunteer women aged between 18 and 60 years. When connecting the points, seven linear segments and one angular measurement on each half of the body, and one medial segment common to both body halves were defined. The volunteers were photographed in a standardized manner. Photogrammetric measurements were performed by three independent observers using the three software packages and compared to direct anthropometric measurements made with calipers and a protractor. RESULTS: Measurements obtained with AutoCAD(r) were the most reproducible and those made with ImageTool(r) were the most similar to direct anthropometry, while measurements with Adobe Photoshop(r) showed the largest differences. Except for angular measurements, significant differences were found between measurements of line segments made using the three software packages and those obtained by direct anthropometry. CONCLUSION: AutoCAD(r) provided the highest precision and intermediate accuracy; ImageTool(r) had the highest accuracy and lowest precision; and Adobe Photoshop(r) showed intermediate precision and the worst accuracy among the three software packages. .

Distribuição de queloide e cicatriz hipertrófica segundo fototipos de pele de Fitzpatrick / Keloid and hypertrophic scar distribution according to Fitzpatrick skin phototypes", "_e": "n

INTRODUÇÃO: Queloide e cicatriz hipertrófica são cicatrizes patológicas com natureza fisiopatogênica comum, denominadas, em conjunto, cicatrizes fibroproliferativas. São mais frequentes em indivíduos de pele mais escura. Contudo, a atual miscigenação dificulta o enquadramento dos pacientes com variadas tonalidades de pele em classificações morfológicas e estáticas (branco ou caucasoide, mulato, pardo, hispânico ou latino, amarelo ou oriental ou mongoloide e negro ou negroide), e diferentes quanto à exposição solar. Sabe-se que pessoas oriundas de países de clima temperado ou frio quando residem em países tropicais aumentam a incidência dessas cicatrizes, principalmente nas áreas de maior exposição solar. Uma relação entre as cicatrizes fibroproliferativas e os fototipos de Fitzpatrick, classificação dinâmica baseada no relato do paciente quanto a sua resposta cutânea após a exposição solar, poderia contribuir para a compreensão da fisiopatologia dessas cicatrizes. Este estudo teve como objetivo investigar a distribuição das cicatrizes fibroproliferativas segundo os fototipos de Fitzpatrick. MÉTODO: Foram avaliados 146 pacientes provenientes do Ambulatório da Disciplina de Cirurgia Plástica da Universidade Federal de São Paulo (Unifesp, São Paulo, SP, Brasil), portadores de qualquer tipo de cicatriz fibroproliferativa, em um ou mais locais do corpo. As cicatrizes fibroproliferativas dos pacientes foram classificadas de acordo com os critérios de Muir em cicatriz tipo queloide (Long-term Evolution, LTE), cicatriz tipo hipertrófica (Short-term Evolution, STE) e cicatriz tipo mista (Intermediate Group, IG), e os tipos de pele foram classificados segundo os fototipos de Fitzpatrick. RESULTADOS: O fototipo Fitzpatrick III e a cicatriz mista foram mais frequentes entre os pacientes avaliados (P = 0,001). Houve associação (P = 0,025) entre as cicatrizes fibroproliferativas e os fototipos de Fitzpatrick, ou seja, quanto maior o fototipo maior a tendência de desenvolvimento de cicatrizes dos tipos queloide e mista. CONCLUSÕES: Os fototipos de pele segundo Fitzpatrick mostraram-se válidos como critério a ser utilizado em estudos de queloide e cicatriz hipertrófica.

BACKGROUND: Keloid and hypertrophic scars have a common physiopathogenic origin and are defined as fibroproliferative scars. Fibroproliferative scars are frequent in individuals with darker skin. However, mixing of "races" renders it difficult to group patients with different skin tones according to morphological and static classifications (white for Caucasians; brown for individuals of Spanish descent (Hispanic/Latino); yellow for individuals of East Asian descent; and black for individuals of African descent) according to their response to sun exposure. It is known that when individuals whose ethnic origin is in colder countries move to tropical countries, they show a higher incidence of these types of scars, which mainly affect parts of the body that are more exposed to the sun. A correlation between fibroproliferative scars and Fitzpatrick phototype, a dynamic classification based on the skin's response to sun exposure, would contribute to an understanding of the pathophysiology of these scars. The aim of this study is to investigate the distribution of fibroproliferative scars according to Fitzpatrick phototypes. METHODS: We classified patients' fibroproliferative scars according to the Muir classification as Long-Term Evolution (keloid scars), Short-Term Evolution (hypertrophic scars), and Intermediate Group (mixed scars), while their skin types were grouped according to the Fitzpatrick classification. RESULTS: Fitzpatrick phototype III and mixed scars were predominant among the patients analyzed (p = 0.001). A correlation (p = 0.025) was observed between fibroproliferative scars and Fitzpatrick phototypes; the higher the phototype, the higher the tendency to develop keloid and mixed scar tissue. CONCLUSIONS: Fitzpatrick skin phototypes proved to be an efficient method to study keloid and hypertrophic scars.

In vitro effect of 470 nm LED (Light Emitting Diode) in keloid fibroblasts / Efeito in vitro do LED (Light Emitting Diode) de 470 nm em fibroblastos de quelóide

Purpose: To quantify keloid fibroblasts after irradiation with 470nm blue LED, in vitro. Methods: Fibroblasts from keloid and adjacent skin have been obtained from 6 patients. Cells have been cultivated and maintained in DMEM culture medium. In Petri dishes, they were irradiated with energy doses of 6J, 12J and 18J. After 24 h, counting was done by the average of the triplicates for each sample. Results: There were no significant differences in the number of irradiated keloid fibroblasts at the studied doses (p=0.261). In adjacent skin fibroblasts, differences were observed (p=0.025) concerning the doses of 18 J and 6 J (p=0.03). Conclusions: There was a reduction in the number of adjacent skin fibroblasts irradiated with 470nm blue LED at the energy dose of 18 J compared to the ones irradiated at the energy dose of 6 J. There were no changes in keloid fibroblasts counting at any of the doses applied, 24 h after irradiation.

Após 24 horas a contagem foi feita pela média da triplicata para cada amostra. Resultados: Não houve diferença na quantidade de fibroblastos de quelóide irradiados nas doses estudadas (p=0,261). Observou-se diferença nos fibroblastos de pele adjacente (p=0,025), com relação às doses de 18 J e 6 J (p=0,03). Conclusões: Houve redução dos fibroblastos de pele adjacente irradiados com LED azul de 470 nm na dose de energia de 18 J em relação à dose de 6 J. Não houve alteração na quantidade de fibroblastos de quelóide nas doses aplicadas após 24 horas da irradiação.

Control of the skin scarring response

There comes a time when the understanding of the cutaneous healing process becomes essential due to the need for a precocious tissue repair to reduce the physical, social, and psychological morbidity. Advances in the knowledge on the control of interaction among cells, matrix and growth factors will provide more information on the Regenerative Medicine, an emerging area of research in medical bioengineering. However, considering the dynamism and complexity of the cutaneous healing response, it is fundamental to understand the control mechanism exerted by the interaction and synergism of both systems, cutaneous nervous and central nervous, via hypothalamus hypophysis-adrenal axis, a relevant subject, but hardly ever explored. The present study reviews the neuro-immune-endocrine physiology of the skin responsible for its multiple functions and the extreme disturbances of the healing process, like the excess and deficiency of the extracellular matrix deposition.

Aproxima-se uma época na qual é fundamental a compreensão do processo cicatricial cutâneo frente à necessidade da restauração tecidual precoce, visando a diminuição das morbidades física, social e psicológica. O avanço no conhecimento acerca do controle das interações entre as células, a matriz e os fatores de crescimento dará maiores informações à Medicina Regenerativa, área de pesquisa emergente da bioengenharia médica. Entretanto, diante do dinamismo e complexidade da resposta cicatricial cutânea torna-se indispensável o entendimento do mecanismo de controle exercido pela interação e sinergismo do sistema nervoso cutâneo e o sistema nervoso central, via eixo hipotálamo-hipófise-adrenal, tema relevante, porém, pouco abordado. O presente estudo revisa a fisiologia neuro-imuno-endócrina da pele, responsável por suas múltiplas funções, e os distúrbios extremos do processocicatricial, como o excesso e deficiência de deposição da matriz extracelular.

What factors affect the quality of life of patients with keloids? / Quais fatores realmente afetam a qualidade de vida dos portadores de queloide?

OBJECTIVE: To evaluate factors that affect the quality of life (QoL) of patients with keloids. METHODS: A study was conducted on 102 patients of both genders between 15 and 70 years old. During initial evaluation, clinical factors, such as keloid visibility, duration and evolution of the disease, previous treatments, types of treatments and recurrence were recorded. Later, patients responded to the QualiFibro questionnaire, which is specific for evaluation of the QoL of patients with keloids and comprises the physical and psychological domains, and six visual numeric scales (VNS), of which three are related to psychological factors (satisfaction with appearance, shame of the disease, and suffering experienced), and the other three are related to physical factors (pruritus, pain and movement restriction). RESULTS: Patients with keloids on non-visible areas of the body (p<0.01) and more than 10 years of disease (p<0,049) reported higher scores on the physical domain of the QualiFibro questionnaire, indicating increased severity compared with patients with keloids on visible areas of the body and disease duration of less than 10 years. There was a positive correlation between psychological (satisfaction with appearance, feelings of embarrassment about the disease and suffering experienced) and physical factors (pruritus, pain and movement restriction) evaluated using the VNSs, and both domains of the QualiFibro questionnaire. CONCLUSION: Results indicate that the physical domain of the QualiFibro questionnaire was the most affected in patients with keloids on non-visible areas and in those with keloids for more than 10 years. Psychological and physical factors associated with keloids as assessed with the VNS affected both psychological and physical domains of QoL.

OBJETIVO: Avaliar quais fatores influenciam a qualidade da vida (QV) dos portadores de quelóide. MÉTODOS: Estudo envolvendo 102 pacientes, de ambos os gêneros, com idade entre 15 e 70 anos. Na avaliação inicial, os fatores clínicos referentes à visibilidade do queloide, tempo de evolução da doença, tratamento prévio, tipos de tratamento e recidiva foram catalogados. Posteriormente, os pacientes responderam ao questionário QualiFibro, composto pelos domínios físico e psicológico, específico para avaliar a QV dos portadores de quelóide, e a seis escalas visuais numéricas (EVN), sendo três escalas em relação a fatores psicológico (satisfação com a aparência, vergonha da doença e sofrimento vivenciado), e três escalas em relação a fatores físicos (prurido, dor e restrição de movimentos). RESULTADOS: A pontuação do domínio físico do questionário QualiFibro foi maior para os portadores de queloide em região não-visível (p<0,01) e com tempo de evolução maior que 10 anos (p<0,049), refletindo piora em relação aos portadores com queloide em região visível e com tempo de evolução de doença menor que 10 anos. Houve correlação positiva entre os fatores psicológico (satisfação com a aparência, vergonha da doença e sofrimento vivenciado) e físicos (prurido, dor e restrição de movimentos) avaliados pelas EVN's e ambos os domínios do questionário QualiFibro (p<0,01). CONCLUSÃO: O domínio físico do questionário QualiFibro foi pior nos portadores de quelóide não-visível e naqueles com duração maior que 10 anos. Os fatores psicológicos e físicos das EVN's, implicados ao queloide, afetaram tanto o domínio físico quanto o domínio psicológico da QV.
