Analysis of YouTube as a source of information for restless leg syndrome.

BACKGROUND: YouTube is one of the major resources for health related videos around the world. OBJECTIVE: The aim of this study was to evaluate the quality of information available on YouTube about restless leg syndrome (RLS). METHODS: A YouTube search was carried out on https://www.youtube.com for videos pertaining to "restless leg syndrome" by using the keyword "restless leg syndrome". The first 100 relevant videos were included in the study. The videos were accepted as "useful" if they provided scientifically correct information about any aspect of RLS. The videos containing scientifically unproven information are defined as "misleading". The overall quality of all videos was subjectively graded using the global quality scale (GQS), a 5-point Likert scale. RESULTS: The median video length for the included videos was 3.39 (0.11-85) minutes, and the median views were 6,055 (32-2351490). The median GQS of useful videos was 3 (1-5). The median number of likes and the median number of comments of personal experience videos were significantly higher than that of the useful and misleading videos. Videos uploaded by the university hospitals frequently issued pharmacological treatment of the RLS; however, those uploaded by practitioners, individual users, and TV or social media accounts were about the non-pharmacological treatment of the RLS. CONCLUSIONS: This study demonstrates that 77% of the videos uploaded on YouTube regarding RLS are in the useful category, whereas only 16 videos were providing misleading information. However, even videos in the useful category do not provide a full and complete description of the RLS.

RESUMO Introdução: O YouTube é um dos principais recursos no mundo para vídeos relacionados à saúde. Objetivo: O objetivo deste estudo foi avaliar a qualidade das informações disponíveis no YouTube sobre a síndrome das pernas inquietas (SPI). Métodos: Realizou-se uma busca no YouTube (https://www.youtube.com) para vídeos pertencentes à 'síndrome das pernas inquietas' usando a palavra-chave 'síndrome das pernas inquietas'. Os primeiros 100 vídeos relevantes foram incluídos no estudo. Foram aceitos como 'úteis' vídeos que fornecessem informações cientificamente corretas sobre qualquer aspecto da SPI. Os vídeos que contêm informações não comprovadas cientificamente são definidos como 'enganosos'. A qualidade geral de todos os vídeos foi avaliada subjetivamente usando a escala de qualidade global (GQS), uma escala Likert de 5 pontos. Resultados: A duração média dos vídeos incluídos foi de 3,39 (0,11-85) minutos e as visualizações médias foram de 6.055 (32-2.351.490). A GQS média dos vídeos úteis foi 3 (1-5). O número médio de curtidas e o número médio de comentários de vídeos de experiências pessoais foram significativamente maiores do que os de vídeos úteis e enganosos. Vídeos enviados por hospitais universitários frequentemente divulgam tratamento farmacológico da SPI; no entanto, aqueles carregados por profissionais, usuários individuais e contas de TV ou mídia social eram sobre o tratamento não farmacológico da SPI. Conclusões: Este estudo demonstrou que 77% dos vídeos carregados no YouTube sobre a SPI estão na categoria útil, enquanto apenas 16 vídeos forneceram informações enganosas. No entanto, mesmo os vídeos na categoria útil não fornecem uma descrição extensa e completa da SPI.

The effects of valproic acid on sciatic nerve of fetal rats and protective effects of folic acid and vitamin E / Efectos del ácido valproico sobre el nervio ciático de fetos de ratas y efectos de protección del ácido fólico y vitamina E

We aimed to investigate the potential harmful effects of maternal valproic acid (VPA) on fetal sciatic nerve, and the protective effects of vitamin E (Vit E) and folic acid (FA) on fetal rats. Valproic acid (400mg/kg), folic acid (400mg/kg) and vitamin E (250 mg/kg) were administered to rats on each of gestation days 8-10. All fetuses were collected on gestation day 20. With thin sections of biopsies, sciatic nerve of fetuses were stained with uranyl acetat and were examined under transmission electron microscope. The fetuses (n:36) were divided into five groups: control, vpa, vpa+fa, vpa+vit e and vpa+fa+vit e groups. In each group; drug procedure, surgical procedure and histological methods were performed. Later, weights and lengths of fetuses in each group were compared and analyzed by One-Way Anova test. Administration of single doses of valproic acid (400 mg/kg) resulted in weight and length loss between control and vpa group. However, length and weight differences between the other groups were not significant. The histopathological findings of control group was normal. In vpa group, it showed extensive degenerative changes especially in myelin coat. In addition, most prominent finding in this group was condensation of collagen fibers in extensively demyelinated samples, while moderately effected areas were relatively normal. Both vpa+fa and vpa+ vit e groups exhibited similar ultrastructural changes, reflecting minimal to moderate degenerative changes. In vpa+fa+vit e group had almost the normal structure. Administration of single doses of valproic acid (400 mg/kg) resulted in a deteriorative effect on sciatic nerve at ultrastructural level. Administration of FA and Vit E had a protective effect to prevent the degenerative changes to a certain degree. Combination of FA and Vit E together following VPA administration had a more potent protective effect. The objective of the present study is to analyze histopathologic changes which ...

El objetivo fue investigar los posibles efectos perjudiciales del ácido valproico (AVP) materno sobre el nervio ciático en fetos y los efectos protectores de la vitamina E (Vit E) y ácido fólico (AF) en fetos de ratas. Se administraron a ratas ácido valproico (400mg/kg), ácido fólico (400mg/kg) y vitamina E (250 mg/kg) en cada uno de los días de gestación 8-10. Todos los fetos fueron recogidos a los 20 días de gestación. Finas secciones de biopsias obtenidas de los nervios ciáticos de fetos fueron teñidos con acetato de uranilo y examinados bajo microscopio electrónico de transmisión. Los fetos (n: 36) fueron divididos en cinco grupos: control, avp, avp+af, avp+vit e y avp+fa+vit e. En cada grupo, se realizaron los procedimientos farmacológicos, quirúrgicos y los métodos histológicos. Los pesos y longitudes de los fetos de cada grupo fueron comparados y analizados usando la prueba One-Way Anova. La administración de dosis únicas de ácido valproico (400 mg / kg) resultó en la pérdida del peso la longitud entre el control y el grupo apv. Sin embargo, las diferencias en la longitud y el peso entre los otros grupos no fueron significativas. Los hallazgos histopatológicos del grupo control fueron normales. En el grupo avp, se mostró especialmente cambios degenerativos en la mielina que envuelve al nervio periféricamente. Además, predominatemente se encontró en las muestras de este grupo fibras colágenas condensadas y zonas ampliamente desmielinizadas, mientras que las zonas moderadamente afectadas eran relativamente normales. Ambos grupos avp+fa y avp+vit e exhibieron cambios ultraestructurales similares, lo que supone un mínimo o moderado cambio degenerativo. El grupo avp+fa+vit e tuvo casi una estructura normal. La administración de dosis únicas de ácido valproico (400 mg / kg) produjo un efecto sobre el deterioro del nervio ciático a nivel ultraestructural. La administración de la AF y vitamina E tienen un efecto protector, en cierta medida, ...
