Educação em neurofisiologia da dor e exercício em adolescentes com dor cervical: conhecimento e aceitabilidade do programa

Mestrado em FisioterapiaEnquadramento: A educação em neurofisiologia da dor (END) tem como finalidade aumentar o conhecimento dos mecanismos biológicos que estão subjacentes à dor do indivíduo, diminui a catastrofização, o medo e a ansiedade associados à dor. O questionário de neurofisiologia da dor - versão utente (QND) é o instrumento mais utilizado para avaliar e monitorizar o conhecimento individual da dor. Este estudo pretende determinar a fiabilidade e validade do QND para o Português Europeu e, avaliar a aceitabilidade e satisfação de adolescentes, relativamente à implementação de um programa de educação em neurofisiologia da dor e exercício. Métodos: O QND foi aplicado a 43 adolescentes com dor cervical, no contexto de um estudo randomizado controlado. Foram testadas a consistência interna, a fiabilidade teste-reteste e a validade discriminante. A investigação qualitativa utilizou entrevistas em grupo (n=4) para avaliar a aceitabilidade e satisfação dos adolescentes (n=21) que tinham sido submetidos à END e exercício, com recurso a análise de conteúdo. Resultados: A versão utente do QND mostrou ter uma consistência interna aceitável (α Chronbach=0.90), fiabilidade teste-reteste moderada (CCI= 0.67 e EPM=1.49) e validade discriminante (p <0.001). Os adolescentes reconhecem a importância do conhecimento adquirido na reconceptualização da dor e na mudança de comportamentos e emoções. Revelam boa aceitabilidade do programa, considerando que está bem estruturado e ajustado às suas necessidades. Conclusões: A versão portuguesa do QND parece ser um instrumento válido e fiável na avaliação de adolescentes com dor cervical idiopática crónica. Um programa de END demonstrou relevância e aceitabilidade em adolescentes com dor cervical.Background: Pain neurophysiology education (PNE) aims to raise awareness of the biological mechanisms that underpin the individual's pain, and decreases catastrophizing, fear and anxiety associated with pain. The neurophysiology pain questionnaire - patient version (NPQ) is the most widely used instrument to assess and monitor individual knowledge of pain. This study aims to determine the reliability and validity of the NPQ for European Portuguese language and assess the acceptability and satisfaction of adolescents regarding the implementation of an education program in neurophysiology of pain and exercise. Methods: The NPQ was applied to 43 adolescents with neck pain, in the context of a randomized controlled trial. Its internal consistency, test-retest reliability and discriminant validity, were assessed. The qualitative research used group interviews (n = 4) to assess the acceptability and satisfaction of adolescents (n = 21) who had undergone PNE and exercise, using content analysis. Results: The patient version of the NPQ showed acceptable internal consistency (α Chronbach = 0.90), moderate test-retest reliability (ICC = 0.67 and SEM = 1.49) and discriminant validity (p <0.001). Adolescents recognized the importance of the acquired knowledge on pain reconceptualization and change of behavior and emotions towards pain. They showed good acceptance of the program, which was considered to be well structured and relevant to their needs. Conclusions: The Portuguese version of NPQ seems to be a valid and reliable tool in the evaluation of adolescents with chronic idiopathic neck pain. A PNE program proved to be easily accepted by adolescents and feasible

Tipo e quantidade de atividade física e uso de dispositivos eletrónicos de estudantes do 7.◦ ao 12.◦ ano: caracterização e associação

ABSTRACT - Aim: To examine the association between self-reported physical activity and self-reported screen based time. Materials and methods: 969 high school students filled in a questionnaire on physical activity and screen based activities. Correlation analysis between time spent in moderate/vigorous physical activities and time spent in screen based activities were performed. Results: No association was found between physical activity and time spent watching TV, playing or using computers. A low correlation was found between time using mobile phones and time spent performing moderate physical activities (r = 0.09, p < 0.05), and vigorous physical activities (r = 0.13, p < 0.05). Conclusions: These findings suggest that screen time is not displacing physical activity.RESUMO - Objetivos: Explorar a associação entre o nível de atividade física e o uso de dispositivos eletrónicos. Materiais e métodos: Novecentos e sessenta e nove alunos do secundário preencheram um questionário sobre atividade física e uso de dispositivos eletrónicos. Foi realizada uma análise de correlação entre o tempo despendido em atividade física moderada e intensa e o uso de dispositivos eletrónicos. Resultados: Não há correlação entre a atividade física e ver televisão, jogar ou usar computadores. Há uma correlação baixa entre o uso de telemóveis e a atividade física moderada (r = 0,09, p < 0,05) e vigorosa (r = 0,13, p < 0,05). Conclusões: Estes resultados sugerem que o uso de dispositivos eletrónicos não interfere com a prática da atividade física.info:eu-repo/semantics/publishedVersio

Orthognathic surgery in the mandibular advance: a systematic review

Introduction: Orthognathic surgery is a standardized procedure used to improve a patient's facial appearance and to correct maxillary and mandibular deformities resulting from malocclusions, disease or trauma. Bilateral sagittal osteotomy of the mandibular ramus is a technique widely used in orthognathic surgery to correct mandibular deformities. Mandibular advancement is a procedure with a high risk of skeletal recurrence, due to the difference between the proximal and distal bone segments. Objective: To carry out a systematic review of orthognathic surgery in the mandibular advance, focusing on the main challenges and importance. Methods: The present study was followed by a systematic literature review model - PRISMA rules. The quality of the studies was based on the GRADE instrument. The risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: Bilateral sagittal osteotomy is the most used technique in mandibular orthognathic surgery, allowing mandibular movements in the sagittal, vertical and transverse directions, with good results and few complications. However, this technique can cause mandibular advancements above 10 mm, strongly pointing to the placement of a bone graft in order to avoid defects and their complications. Therefore, in orthognathic surgery, bone grafting can accelerate bone formation

Main approaches to malocclusions and orthognathic surgery in facial aesthetic: an integrative review

Introduction: In the scenario of orthodontic corrections, orthognathic surgery makes it possible to restore the functional and aesthetic patterns of the face, and non-surgical or minimally invasive procedures have optimized the results of ortho-surgical facial treatments. Objective: the present study aimed to perform a systematic review of the main information about orthognathic surgery in malocclusions, as well as to present the aesthetic importance. Methods: Clinical studies with qualitative and/or quantitative analysis were included, following the rules of the systematic review-PRISMA. Results and Conclusion: A total of 107 articles were found involving "malocclusions and orthognathic surgery". A total of 47 articles were evaluated in full, and 33 were included and discussed in this study. Aesthetic/functional rehabilitation is necessary until the eruption of permanent successor teeth occurs. A practical option to obtain this rehabilitation is through the installation of aesthetic or functional space maintainers. These are orthodontic devices that replace one or more deciduous teeth and are used to preserve the space destined for the permanent tooth successor, preventing it from suffering deviations during its eruption. The facial typology seeks to redefine the relationships between deleterious habits and malocclusions, through the valuation of individual morphological characteristics, which will lead to craniofacial growth and development to assume certain facial types. Therefore, due to the aging of the stomatognathic apparatus the orofacial functions can be modified, such as malocclusion, therefore for greater effectiveness and longevity of the final result of the orthodontic treatment, the indefinite use of fixed inferior containment should be established and accompanied by the professional

Genetic diversity and population structure of cotton (Gossypium hirsutum L. race latifolium H.) using microsatellite markers

Cotton (Gossypium spp.) is the world?s leading natural fiber crop and is cultivated in diverse temperate and tropical areas. The proper use of cotton genetic resources allows breeders to identify and select superior parents for breeding programs. In this sense, molecular markers are important tools for polymorphism identification in genetic diversity analyses. The objective of this study was to evaluate genetic diversity and population structure in tetraploid cotton (Gossypium hirsutum L. race latifolium H.) by means of microsatellite markers. 43 cultivars and inbred lines from Africa, United States and Brazil were analyzed. From a total of 33 SSRs markers, 15 markers revealed 104 polymorphic SSR alleles. Four groups were identified applying different methods (the probabilistic method, principal coordinates analysis and neighbor joining tree). American cultivars and inbred lines were included in group I; African cultivars in group II; and Brazilian cultivars in groups II, III and IV. The FST index indicated high genetic variability among the cultivars and inbred lines studied. In general, American cultivars were the most divergent in relation to African and Brazilian ones. The dissimilarity index ranged from 0.06 to 0.90 and the lowest genetic divergence was observed between TAMCOT22 and TAM96WD-69s(L). Combination of American cultivars and inbred lines with African and Brazilian cultivars is recommended to obtain superior transgressive segregants in order to improve yield in cotton breeding programs.Fil: Domingos Moiana, Leonel.

Pain, pain intensity and pain disability in high school students are differently associated with physical activity, screening hours and sleep

Background: Studies exploring the association between physical activity, screen time and sleep and pain usually focus on a limited number of painful body sites. Nevertheless, pain at different body sites is likely to be of different nature. Therefore, this study aims to explore and compare the association between time spent in self-reported physical activity, in screen based activities and sleeping and i) pain presence in the last 7-days for 9 different body sites; ii) pain intensity at 9 different body sites and iii) global disability. Methods: Nine hundred sixty nine students completed a questionnaire on pain, time spent in moderate and vigorous physical activity, screen based time watching TV/DVD, playing, using mobile phones and computers and sleeping hours. Univariate and multivariate associations between pain presence, pain intensity and disability and physical activity, screen based time and sleeping hours were investigated. Results: Pain presence: sleeping remained in the multivariable model for the neck, mid back, wrists, knees and ankles/feet (OR 1.17 to 2.11); moderate physical activity remained in the multivariate model for the neck, shoulders, wrists, hips and ankles/feet (OR 1.06 to 1.08); vigorous physical activity remained in the multivariate model for mid back, knees and ankles/feet (OR 1.05 to 1.09) and screen time remained in the multivariate model for the low back (OR = 2.34. Pain intensity: screen time and moderate physical activity remained in the multivariable model for pain intensity at the neck, mid back, low back, shoulder, knees and ankles/feet (Rp2 0.02 to 0.04) and at the wrists (Rp2 = 0.04), respectively. Disability showed no association with sleeping, screen time or physical activity. Conclusions: This study suggests both similarities and differences in the patterns of association between time spent in physical activity, sleeping and in screen based activities and pain presence at 8 different body sites. In addition, they also suggest that the factors associated with the presence of pain, pain intensity and pain associated disability are different

Musculoskeletal multisite pain and patterns of association after adjusting for sleep, physical activity, and screen time in adolescents

Study Design. Cross-sectional. Objective. This study aims to describe how pain at multiple body sites is associated after controlling for other predictive factors such as age, sex, sleeping hours, time spent in physical activity, and time spent in screening based activities in adolescents aged 13 to 19 years. Summary of Background Data. The prevalence of multisite pain in adolescents is high, but studies investigating the patterns of association between painful body sites are scarce. Methods. Pain for the last 3 months was assessed using Nordic Musculoskeletal Questionnaire. In addition, data on time spent in moderate and vigorous physical activity, sleeping, and in screen based activities were also assessed. Results. In univariable analysis of associations, there is a significant association between most painful body sites (odds ratio [OR\ between 1.52 and 3.73, P<0.05). After controlling for age, sex, physical activity, sleep and screen time, most of the previous associations remain significant (OR between 1.50 and 3.07, P<0.05).publishe
