ABSTRACT

ABSTRACT Objective: To evaluate smartphone addiction and postural alterations in the cervical region in adolescents. Methods: A cross-sectional study with 281 adolescents (15 to 19 years old), attending the 1st to the 3rd grades of High School, carried out between September and October 2019 in the city of Fortaleza, Ceará, Brazil. Data collection took place in two stages. In the first, they answered four self-administered questionnaires: sociodemographic questionnaire, health conditions and smartphone use, Nordic Musculoskeletal Symptom Questionnaire (NMQ), Self-Report Questionnaire (SRQ-20) and the Smartphone Addiction Inventory (SPAI-BR). In the second stage, they were submitted to photogrammetry using the Postural Assessment Software (SAPO) and anthropometric assessment (weight and height). The software SPSS Statistics version 23.0 was used for data analysis. Results: Of the total number of adolescents, 63.3% (n=178) showed smartphone addiction, using it for 5.8 hours (±3.5) during the week and 8.7 (±4.0) hours on the weekend. When analyzing postural alignment in the anterior view, a significant reduction in the lateral head tilt was observed when typing on the smartphone (p=0.002) compared to the anatomical position (baseline). In the lateral view, an increase in head anteriorization was observed during smartphone use (p<0.05). There was an association between smartphone addiction and head anteriorization (p<0.05). Conclusions: The use of the smartphone in the typing position causes postural alterations in the cervical region, especially in adolescents with smartphone addiction. Therefore, health promotion measures that alert adolescents to the adverse effects caused by prolonged smartphone use are necessary.


RESUMO Objetivo: Avaliar a dependência do smartphone e a alteração postural da região cervical em adolescentes. Métodos: Estudo transversal, com 281 adolescentes (15 a 19 anos), que frequentavam da 1ᵃ à 3ᵃ série do ensino médio, realizado entre setembro e outubro de 2019 na cidade de Fortaleza, Ceará, Brasil. A coleta dos dados ocorreu em duas etapas. Na primeira, eles responderam a quatro questionários autoaplicáveis: questionário sociodemográfico, condições de saúde e uso do smartphon e, Questionário Nórdico de Sintomas Musculoesqueléticos (NMQ), Self-Report Questi onnaire (SRQ-20) e o Smartphone A ddiction Inventory (SPAI-BR). Na segunda etapa, foram submetidos a fotogrametria pelo Software de Avaliação Postural (SAPO) e avaliação antropométrica (peso e altura). Para a análise dos dados, foi utilizado o SPSS Statistics versão 23.0. Resultados: Do total, 63,3% (n=178) dos adolescentes apresentaram dependência do smartphone, com o uso de 5,8 horas (±3,5) durante a semana e 8,7 (±4,0) no fim de semana. Ao analisar o alinhamento postural na visão anterior, observou-se redução significativa da inclinação lateral de cabeça ao digitar no smartphon e (p=0,002) comparado à posição anatômica (baseline). Na visão lateral foi constatado aumento da anteriorização de cabeça durante o uso do smartphon e (p<0,05). Houve associação da dependência do smartphone com a anteriorização de cabeça (p<0,05). Conclusões: O uso do smartphone na posição de digitação causa alteração postural na região cervical, destacadamente naqueles que apresentam dependência do dispositivo. Dessa forma, são necessárias medidas de promoção de saúde que alertem os adolescentes sobre os efeitos adversos causados pelo uso prolongado do smartphone.

ABSTRACT

Through a wide range of cellular and molecular events, the peripheral nervous system is endowed with great regenerative capacity, responding immediately to injuries that occur along the length of the nerve. The aim of this study was to histomorphometrically assess the degree of maturity of the nervous tissue and possible microscopic changes in newly formed nerve segments 60 days after experimental neurotmesis of the sciatic nerve in rats. Control Group (CG) and an Injury Group (IG) were used. IG underwent neurotmesis of the sciatic nerve of the right foot, with immediate surgical repair using the tubulization technique. 60 days following experimental surgery, animals from both groups had their sciatic nerves collected for histomorphometric analysis. Statistical analysis was performed, using the Student t-test for independent samples, expressed as mean ± standard deviation, with 5% significance. In the event of injury, peripheral nerve tissue is mobilized in an intrinsic self-healing process. 60 days following of nerve regeneration in neurotmesis injury, the peripheral nerve presents a segment joining the newly formed neural stump. The new stump has a number of regenerated axons compatible with an intact nerve, but which still show great immaturity in the axonal structural layers of the nerve.


Mediante diversos procesos celulares y moleculares, el sistema nervioso periférico tiene una gran capacidad regenerativa, respondiendo inmediatamente a las lesiones ocurridas a lo largo de su extensión. El objetivo de este estudio fue evaluar histomorfométricamente el grado de madurez del tejido nervioso y los posibles cambios microscópicos en los segmentos nerviosos recién formados 60 días después de la neurotmesis experimental en el nervio ciático de ratas. Se utilizaron 9 ratas (Wistar) separadas en grupo control (GC, n= 4) y Grupo lesión (GL, n= 5). A los 60 días de vida, el grupo GL fue sometido a neurotmesis del nervio ciático de la miembro posterior derecho, con inmediata corección quirúrgica con la técnica de tubolización. Completados 60 días luego de la cirugía experimental, los animales de ambos grupos fueron anestesiados y sus nervios ciáticos seccionados para el análisis histomorfométrico. Se realizó un análisis estadístico utilizando la prueba t de Student para muestras independientes, expresado como media ± desviación estándar, con un 5% de significancia. A los 60 días de la lesión por neurotmesis, el nervio ciático del GL presentó alteraciones histomorfométricas significativas para las variables: número de vasa nevorum, densidad de fibras mielínicas, diámetro axonal y de fibras mielínicas, espesor de la vaina de mielina y razón G, con similitud solamente para los números absolutos de fibras mielínicas regeneradas. El nervio periférico durante su proceso regenerativo, pasa por grandes alteraciones estructurales, siguiendo una secuencia coordinada de acciones, que dependiendo de las condiciones del microambiente donde ocurre esta regeneración, podrá ser clave para el nivel de regenerecion nerviosa periférica.

ABSTRACT

Estudios previos demostraron que la morfología del acromion y sus respectivas relaciones con el tubérculo supraglenoideo y el proceso coracoides, son de fundamental importancia en la determinación del espacio subacromial. Las variaciones de estas estructuras pueden provocar el principio del síndrome del impacto, también conocido como síndrome del pinzamiento del espacio subacromial. Sin embargo, se observa la falta de relatos en la literatura sobre los diferentes padrones morfométricos del acromion. El objetivo de este estudio fue establecer un padrón morfométrico del acromion, a través de la determinación de su largo, grosor y proyección anterior, además de determinar su relación con el proceso coracoides y el tubérculo supraglenoideo. Fueron analizadas 60 escápulas (37 derechas y 23 izquierdas) de individuos adultos, de la colección de piezas óseas del Departamento de Anatomía de la Universidad Federal de Pernambuco, Brasil. Con la ayuda de un paquímetro y una cinta métrica de perimetría fueron realizadas medidas del largo, grosor y proyección anterior del acromion y también de las distancias del acromion al tubérculo supraglenoideo y al proceso coracoides. Los resultados obtenidos fueron: largo del acromion: 4,96cm + 0,46 (74%); grosor: 0,72cm + 0,1 (72%); proyección anterior: 4,llcm + 0,42 (67%); distancia entre el acromion y el tubérculo supraglenoideo: 2,95cm + 0,35 (67%); distancia entre el acromion y el proceso coracoides: 3,8cm + 0,52 (64%). No observamos variaciones entre las escápulas derechas e izquierdas. El análisis morfométrico del acromion debe ser utilizado como base auxiliar para los estudios, procurando un mejor conocimiento de las patologías que existen en esa región.


Previous studies demonstrated that the morphology of the acromion and its respective relations with the uppermost point of the glenoid and the coracoid process is very important in the determination of subacromial space. The variations of these structures can predispose the beginning of the Impingement Syndrome. However, there is a shortage of reports on hterature about the different acromion's morphometric samples. The purpose of this study was to determine a morphologic pattern of the acromion, through the determination of its length, thickness, front projection, and its relation with the uppermost point of the glenoid and the coracoid process. We used 60 scapulae (37 right and 23 left) of adults from Departamento de Anatomia da Universidade Federal de Pernambuco, Brazil. To measure the length, thickness and front projection of acromion, and the distances from acromion to the uppermost point of the glenoid and to the coracoid process were used a calipers and a tape measure. We found these results: acromion length: 4.96cm + 0.46 (74%); thickness: 0.72cm + 0.1 (72%); front projection: 4.11cm + 0.42 (67%); distance between acromion and the uppermost point of the glenoid: 2.95cm + 0.35 (67%); distance between acromion and coracoid process: 3.8cm + 0.52 (64%). We did not find differences between right and left scapulaes. The morphometric analysis of the acromion should be used like an auxiliary basis to studies that promote a better knowledge about the disease that appear in this area.

ABSTRACT

Objetivo: Avaliar em ratos eutróficos ou desnutridos precocemente, o efeito da radiação não ionizante sobre o efeito microbicida dos macrófagos alveolares (MA), infectados por C. a. Métodos: Foram utilizados 12 ratos machos, Wistar, idade entre 60 a 120 dias, separados nos grupos: nutrido (n=6) e desnutrido (n=60. MA foram recuperados e as células foram isoladas, contadas e separadas na proporção de 10 células/ml em meio RPMI 1640 e colocadas em tubos Eppendorf (1ml/tubo). Parte foi submetida à presença de CEM senoidal de freqüência ultra baixa (60Hz) com densidade de fluxo de 0,16mt, 1h, enquanto que a outra não. 200µl do sobrenadante foram coletados após a irradiação e adicionados a 2,800µl de meio BHI E 10 fungos (C. a)/ml. Após 30 min de incubação, estuda a 37°; atmosfera úmida, retirou-se 1µl da mistura e semeou-se em placa de Petri com meio ágar-sabouraud. Após 24h na estufa foram contadas as Unidades Formadoras de Colônias. Os dados foram expressos em média ± erro padrão. Utilizou-se teste t de Student com significância estatística para p < 0,05. Resultados/Conclusão: Houve redução no peso corpóreo dos animais desnutridos em relação aos nutridos. No grupo nutrido, verificou-se aumento do potencial microbicida dos macrófagos nos ratos irradiados em relação aos não irradiados e esse dado não foi verificado no grupo de animais desnutridos.
