- Ingresso nas Forças Armadas: Um Estudo EspacialPublication . Fernandes, HenriqueO recrutamento para as Forças Armadas tem estado na ordem do dia e tem surgido nos órgãos de comunicação social referências várias neste domínio. Desde o final do Serviço Militar Obrigatório, esta temática tem sido abordada em diversos fóruns, de uma forma fundamentalmente descritiva e de natureza qualitativa. Neste trabalho, com a utilização de um Sistema de Informação Geográfica, explorou-se a natureza espacial da informação, articulando-a com medidas de associação de variáveis, no sentido de se identificarem dimensões geográficas e estruturais que pudessem relacionar-se com a predisposição de ingresso na Força Aérea. Para tal, foi utilizada informação do ramo no que respeita a dados de recrutamento, foi descarregada e tratada informação estatística dos sítios do INE e Pordata, e foi construída uma variável para operacionalizar a distância. Como resultado, identificaram-se um conjunto de dimensões que têm relação com a predisposição de ingresso na Força Aérea, nomeadamente a distância, o desemprego e a estrutura familiar. Foi ainda construído um modelo multivariado para explicar a predisposição de ingresso, resultando em modelos que incluem a distância e o desemprego, como preditores para a explicar conjuntamente. Abstract: Recruitment to the Armed Forces has been on the agenda and many references have emerged in the media. Since the end of the military conscription, this theme has been approached in several forums, in a fundamentally descriptive and qualitative way. In this work, using a Geographic Information System, the spatial nature of the information was explored and articulated with measures of variables associations, in order to identify geographic and structural dimensions that could be related to the predisposition to join the Air Force. To achieve this, branch information was used in relation to the recruitment data, statistical information from INE and Pordata sites was downloaded and processed, and a variable was constructed to operate the distance. As a result, we identified a set of dimensions that are related to the predisposition to join the Air Force, namely distance, unemployment and family structure. A multivariate model was also constructed to explain the predisposition to join, resulting in models that include distance to the units and unemployment, as predictors to explain jointly this predisposition.
- Transcutaneous auricular vagus nerve stimulation modulates masseter muscle activity, pain perception, and anxiety levels in university students : a double-blind, randomized, controlled clinical trialPublication . Ferreira, Luciano Maia Alves; Brites, Ricardo; Fraião, Gonçalo; Pereira, Gonçalo Pereira; Fernandes, Henrique; Brito, José Américo Almeida de; Generoso, Laura Pereira; Capello, Maria Gabriela Maziero; Pereira, Gabrielly Santos; Scoz, Robson Dias; Silva, Josie Resende Torres; Silva, Marcelo LourençoIntroduction: Chronic anxiety is a statemarked by sustained activation of the masseter muscle, manifesting in both mental and physical strain. This prolonged tension can significantly impact mental wellbeing and cognitive abilities, posing a risk for a range of health complications. This double-blind, randomized, controlled clinical trial investigated the impact of transcutaneous auricular vagus nerve stimulation (TAVNS) on masseter muscle activity, pressure pain threshold (PPT), and anxiety levels in university students with elevated anxiety. Methods: Forty-two participants meeting inclusion criteria were randomly assigned to either active TAVNS or sham TAVNS groups. Various parameters, including masseter muscle electromyographic (EMG) signals, PPT, and Beck Anxiety Inventory (BAI) scores, were assessed before pretreatment, immediately after the intervention week, and 2 weeks follow-up. Results: Active TAVNS significantly reduced both left and right masseter activation during resting mandibular position, persisting for 2 weeks post-intervention. Additionally, TAVNS induced a lasting decrease in both left and right masseter PPT, indicative of altered pain perception. Notably, BAI scores showed a substantial reduction, emphasizing TAVNS as a potential intervention for anxiety, with effects maintained at the 2-week follow-up. Discussion: This study provides comprehensive insights into the multifaceted effects of TAVNS on physiological and psychological aspects associated with anxiety in university students. The promising results underscore TAVNS as a potential neuromodulatory intervention for anxiety-related conditions, warranting further research and clinical exploration.
