INTERAÇÃO ENTRE CEFALEIA E DISFUNÇÃO TEMPOROMANDIBULAR
Authors: Jamil Silva de Arruda Farid
Published: February 2025

Introdução: Cefaleia é definido como uma dor localizada na cabeça acima da linha orbitomeatal e/ou
crista nucal, também se sabe que algumas síndromes de dor de cabeça refletem na face e são tipicamente
ipsilaterais a crises de cefaleia. A disfunção temporomandibular (DTM), que refere- se a um grupo de
problemas clínicos que envolvem os músculos mastigatórios, a articulação temporomandibular (ATM)
e estruturas relacionadas tem a cefaleia como sintoma primário, sendo a dor crônica mais comum que
afeta a face e o dentista é frequentemente o primeiro profissional convocado em casos de dor orofacial,
sendo necessário para reduzir erros de diagnóstico. Objetivos: O objetivo deste trabalho é considerar
todas as causas odontológicas que levam à cefaleia, tratando a DTM como a principal e fomentar novas
formas de manejo clínico para a diminuição desse problema que atinge a população em grande escala.
Material e Métodos: Foi desenvolvida uma pesquisa bibliográfica, que consistiu na busca em bases de
dados de artigos científicos relacionados ao tema. Os artigos encontrados foram lidos e analisados e,
quando relevantes, utilizados na redação deste trabalho. Resultados e Discussão: Uma explicação para
esse achado seria a presença de hábitos parafuncionais, como o bruxismo que pode levar à hiperfunção
dos músculos mastigatórios e, consequentemente, a dores de cabeça. Foi reconhecido que fatores
periféricos e centrais têm um papel na dor da DTM, que muitas vezes é confundida com dor facial
primária, como a cefaleia do tipo tensional. Um estudo mostrou que a prevalência de DTM em pacientes
com cefaleias primárias era de 56,1%. A cefaleia visualizada na DTM mostra um padrão específico.
Ocorrem nas regiões temporal, frontal e retro-ocular, podendo ser unilateral ou bilateral e sua intensidade
varia de leve a grave. Esse tipo de cefaleia ocorre com mais frequência no final do dia. Os estudos
mostraram uma preponderância no sexo feminino e relação com mudanças no estado emocional e
cansaço. Conclusão: Os estudos mostraram uma preponderância no sexo feminino e relação com
mudanças no estado emocional e cansaço. Alguns dos tratamentos analisados possíveis são os
medicamentos, osteopatia, terapia cognitivo- comportamental ou fisioterapia, mas também há condutas
alternativas como controlar o estresse, relaxar e fazer meditação. As placas oclusais são o tratamento
padrão-ouro na Odontologia.

Published: February 2025

Introdução: A microtomografia computadorizada periférica de alta resolução (HR-pQCT) é uma
tecnologia nova, desenvolvida nos últimos 15 anos. Ela proporciona imagens tridimensionais detalhadas
com baixas doses de radiação, permitindo uma avaliação precisa da densidade e da estrutura óssea. A
HR-pQCT é valiosa para o diagnóstico e monitoramento de doenças ósseas devido à sua capacidade de
fornecer informações detalhadas sobre a microarquitetura óssea. No entanto, sua aplicação fora do
ambiente de pesquisa ainda é limitada, sendo predominantemente usada em estudos acadêmicos.
Objetivos: Este trabalho teve como objetivo revisar e analisar a aplicação da HR-pQCT na Medicina,
explorando suas potencialidades e limitações. Buscou-se entender como a HR-pQCT pode ser integrada
à prática clínica e identificar os avanços e desafios associados à sua utilização em diversas condições de
saúde óssea. Material e Métodos: Este estudo é uma revisão integrativa sobre a aplicação da HR-pQCT
na Medicina. Foi realizada uma busca nas bases de dados Google Scholar e PubMed, utilizando os
descritores em inglês "high- resolution peripheral computed tomography" e "medical application", com
foco nos últimos 10 anos para garantir a relevância dasinformações. Resultados e Discussão: Os artigos
selecionados destacaram várias aplicações da HR-pQCT na prática médica, como a avaliação da
densidade mineral óssea, a análise da microarquitetura óssea e o monitoramento de condições como
osteoporose e doenças metabólicas ósseas. Apesar dos avanços na tecnologia, a adoção clínica da HRpQCT enfrenta desafios como o alto custo dos equipamentos, a necessidade de formação especializada
e a integração com outras modalidades de imagem. A discussão abordou as vantagens da HR-pQCT em
comparação com técnicas convencionais e suas limitações, como a necessidade de mais estudos para
validar seus benefícios clínicos e sua acessibilidade. Conclusão: A HR-pQCT representa um avanço
significativo na imagem óssea, oferecendo uma análise detalhada com baixa exposição à radiação.
Embora a tecnologia seja promissora, sua aplicação clínica ainda é limitada devido a fatores como custo
e necessidade de especialização. Futuras pesquisas e desenvolvimentos poderão facilitar sua maior
adoção na prática médica, melhorando o diagnóstico e o monitoramento de doenças ósseas.

Published: February 2025

Introdução: A hipertensão arterial é uma condição crônica caracterizada pela elevação persistente da pressão arterial, sendo definida por níveis iguais ou superiores a 140 mmHg de pressão sistólica ou 90 mmHg de pressão diastólica. Quando não tratada adequadamente, pode evoluir para crises hipertensivas, que são classificadas como emergências, podendo causar danos a órgãos vitais, exigindo intervenção médica imediata. Segundo a Organização Mundial da Saúde (OMS), entre 1990 e 2019, o número de indivíduos com hipertensão passou de 650 milhões para 1,3 bilhão. Embora seja frequentemente assintomática, essa doença silenciosa pode desencadear graves complicações cardíacas e sistêmicas. Objetivo: Relatar a experiência de atendimento a um paciente em crise hipertensiva, destacando os desafios clínicos e a importância do manejo adequado para prevenir complicações. Metodologia: Este relato de experiência baseia-se na vivência de um acadêmico, durante o estágio extracurricular. Relato de Caso: Paciente do sexo feminino, 67 anos, deu entrada na UPA com queixa de cefaleia intensa após realizar atividades físicas em uma praça próxima de sua casa. Na triagem, constatou-se uma elevação atípica da pressão arterial, atingindo 300x180 mmHg, o que gerou preocupação imediata. A pressão foi medida em três aparelhos diferentes para confirmação. Durante a anamnese, a paciente relatou que havia discutido com o filho no dia anterior e esquecera de tomar seus medicamentos matinais (Metoprolol, Losartana e Hidroclorotiazida). Os exames iniciais revelaram uma frequência cardíaca de 73 bpm, ausculta cardíaca com bulhas normorrítmicas e eletrocardiograma sem alterações patológicas. A ausculta pulmonar estava limpa, com murmúrio vesicular presente e bilateralmente preservado, pupilasisocóricas e fotorreativas, Glasgow 15, e a paciente encontrava- se corada, hidratada e anictérica. Devido à crise hipertensiva, foi administrado uma ampola de Nitroprussiato (25 mg/ml) diluído em 248 ml de Soro Glicosado, com infusão contínua a 5 ml/hora, uma dosagem incipiente adequada para o seu peso de 70 kg. A meta inicial era reduzir a pressão sistólica para 225x240 mmHg na primeira hora. Após esse período, a meta foi alcançada, com a pressão arterial da paciente estabilizada em 210x120 mmHg, demonstrando uma resposta eficaz ao tratamento. Conclusão: Ao presenciar a hipertensão com cifras tão altas (pouco visto em literatura), foi possível ver a capacidade efetiva do fármaco de primeira linha no controle da pressão arterial. Uma conduta baseada nos parâmetros do protocolo de crise hipertensiva fora fundamental para estabilização da paciente.

Authors:   aculty of Pharmacy, University of Health Science, thammavong sonesay
Published: February 2025

Mucuna pruriens (M. pruriens) has been utilized in traditional medicine for thousands of years across various Asian countries, including Laos. It is recognized for its significant biological properties, such as strengthening the body and enhancing male sexual fertility. However, ensuring the safety and efficacy of its use is vital, especially regarding potential heavy metal contamination. Heavy metals such as lead (Pb), cadmium (Cd), and arsenic (As) can cause serious health problems, including cancer and Alzheimer’s disease. Thus, contamination in traditional medicines presents a global health risk, particularly when levels exceed WHO guidelines. This study aims to assess heavy metal contamination (Pb, Cd & As) in M. pruriens seeds sourced from nine provinces across three regions of Laos, using Atomic Absorption Spectroscopy (AAS). The results indicate that all samples contained heavy metal levels within WHO limits, with lead concentrations ranging from 0.139 ± 0.08 ppm to 8.818 ± 0.17 ppm and cadmium levels from 0.105 ± 0.02 ppm to 0.211 ± 0.01 ppm. Notably, arsenic was not detected in any of the samples. These findings suggest that the M. pruriens seeds collected from Laos are safe for development into food supplements and for use in traditional medicine.

La política de mitigación del cambio climático y el doble dividendo: el caso de España
Authors:   Universidad del País Vasco, González Ruiz de Eguino Mikel , Gallastegui Zulaica Mª Carmen ,   Universidad del País Vasco
Published: February 2025

Este trabajo analiza la hipótesis del doble dividendo aplicado a la política de control del cambio climático en España utilizando un modelo de equilibrio general aplicado dinámico. El análisis empírico realizado pone de manifiesto que no es posible encontrar un doble dividendo fuerte en los escenarios planteados. Los resultados son más variados en lo que respecta a la existencia de un doble dividendo débil. La reducción de impuestos al trabajo y al consumo disminuye los costes de mitigación en mayor cuantía que la opción de devolver las recaudaciones vía transferencias. Los resultados, sin embargo, también muestran que la hipótesis del doble dividendo débil no está garantizada y tiene que ser examinada en detalle para cada caso concreto.

Published: February 2025

Las medidas emprendidas contra el cambio climático pueden entrar en conflicto con el logro de determinados objetivos económicos. Por tanto, el diseño de políticas económicas y ambientales puede entenderse como un problema de decisión multicriterio. En este trabajo se aborda el diseño de políticas públicas combinando técnicas multicriterio y la modelización de equilibrio general computable. En particular, se define el concepto de política eficiente y se aplica dicha definición a la economía española con datos del año 2000. El método propuesto permite construir un conjunto de políticas eficientes en términos de crecimiento económico y emisiones contaminantes, así como ampliar el conjunto de objetivos de política.
El mercado de emisiones de la Unión Europea: ¿Mitigación o generosidad?
Authors:   Universidad de La Laguna, Padrón Fumero Noemí
Published: February 2025

Este artículo analiza el funcionamiento del Régimen de Comercio de Emisiones de la Unión Europea basado en la información detallada del registro de instalaciones europeo para los tres años de duración de la Fase I (2005-2007). El análisis revela que el nivel de emisiones verificadas de CO2 ha estado por debajo del nivel de permisos asignados (EUA) a lo largo de dicha fase, generando un exceso de oferta de asignaciones por valor de 152 millones de toneladas y una senda de precios de CO2 decreciente. Si bien algunos autores han apuntado la posibilidad de que este exceso de oferta sea indicativo de una sobreasignación de EUA en el conjunto de la UE, este artículo explora el supuesto de que sea la irreversibilidad en la inversión en un escenario con restricciones de transferencia intertemporal de permisos la que explique los resultados observados.

Published: February 2025

El presente artículo discute el sistema de primas («feed-in tariffs») y el esquema de comercio de certificados verdes, que son los dos ejemplos más conocidos y populares de instrumentos de política de fomento de la electricidad renovable. Se comparan ambos esquemas en lo concerniente a su impacto en situaciones de incertidumbre, los riesgos de mercado y regulatorios, el impacto en la innovación tecnológica, el efecto sobre el precio de la electricidad y el saldo fiscal de las Administraciones, así como algunos aspectos del balance eficiencia/equidad (efecto «NIMBY»). Las conclusiones no son nítidamente favorables a uno u otro mecanismo de regulación. Las modalidades de implementación, la estructura de costes de la tecnología considerada, la disponibilidad de recursos y las condiciones del entorno existentes en mercados directamente relacionados con el eléctrico (financieros, de recursos energéticos primarios, de gestión de riesgos, etc.), harán que en cada caso sea más apropiada la adopción de un esquema u otro.

En este trabajo se analiza la idoneidad de una amplia gama de procedimientos de reducción de las emisiones de CO2 en el sector del transporte, en función de varios criterios y se presta especial atención al transporte de pasajeros por carretera. Se identifican las ventajas y desventajas de cada instrumento con respecto a otros, sus interacciones y las mejores combinaciones de los mismos.
Evaluación de la reforma del pacto de estabilidad y crecimiento: ¿Nuevo y mejor?
Authors:   Universidad de Oporto, Alves Rui Henrique , Afonso Oscar ,   Universidad de Oporto
Published: February 2025

A pesar de la reforma del Pacto de Estabilidad y Crecimiento (PEC) ocurrida en 2005, la aplicación real de las normas vinculantes de disciplina fiscal en la Unión Monetaria Europea sigue resultando muy polémica, tanto en el ámbito académico como en el político, incluso a pesar de que algunas de las críticas lanzadas contra el PEC original se han incorporado al PEC reformado. El objetivo de este artículo es evaluar los cambios acaecidos en la reforma de dicho Pacto, teniendo en cuenta las propiedades de las normas fiscales «ideales» de Kopits y Symansky. Nuestro estudio defiende un evidente aumento de la flexibilidad, pero advierte de la posible aparición de problemas de aplicación y la falta de avances en la coordinación de las políticas fiscales nacionales. En este contexto nos planteamos la necesidad de nuevas mejoras a escala europea en la definición y puesta en marcha de las políticas fiscales nacionales.

Evaluating the reform of the stability and growth pact: new and better?
Authors:   Universidad de Oporto, Alves Rui Henrique , Afonso Oscar ,   Universidad de Oporto
Published: February 2025

In spite of the recent reform of the Stability and Growth Pact (SGP) and the fact that some of the questions raised by those who criticised the initial framework for fiscal discipline may have been considered, the discussion on the implementation of binding fiscal rules in the European Monetary Union is still a matter of important controversy in both academic and political fields. The objective of this paper is to evaluate the changes contained in the reformed SGP by taking into consideration the properties for “ideal” fiscal rules put forward by Kopits and Symansky. Our analysis points towards a clear increase in flexibility together with the probable emergence of new enforcement problems and no advances in terms of the coordination of more effective fiscal policies. In this context, we discuss the need for new improvements within the European framework for the definition and implementation of national fiscal policies.
Reviving the home owners' loan corporation to avoid a recession in USA
Authors:   Journal of Post Keynesian Economics, Davidson Paul
Published: February 2025

The original subprime mess has ultimately resulted in an insolvency problem for millions of U.S. households. The government’s fiscal “stimulus” plan does not directly address this insolvency problem. The Federal Reserve pumping in more liquidity will not end the housing insolvency problem. Instead, I suggest a tried and true comprehensive program to create a major federal facility to refinance mortgages at low rates and extended maturities, and to finance new investment in private sector housing. The goal of this new lending facility will be to: 1) end the insolvency housing problem; 2) avoid a serious recession, and prevent similar financial bubbles due to securitization of loan-backed financial assets from developing in the future.

Comportamiento presupuestario y crecimiento económico en los países de la Unión Europea, 1984-2003
Authors:   Universidad Autónoma de Madrid, Vara Miranda María Jesús
Published: February 2025

El trabajo expone, en primer lugar, los argumentos con los que se defiende la necesidad de reducir la actividad presupuestaria del Estado y de minimizar el déficit fiscal conforme al consenso institucionalizado en el Tratado de Maastricht y el Pacto de Estabilidad y Crecimiento. Después analiza la evolución de las principales variables presupuestarias en las economías de la Unión Europea y establece una tipología de países conforme a la dimensión de su actividad presupuestaria. En tercer lugar realiza tres aproximaciones a la evidencia empírica desde las que se argumenta la gran dificultad de establecer algún tipo de relación causal entre la evolución de las variables fiscales o el tamaño de la actividad presupuestaria y el crecimiento económico de los países europeos en el intervalo 1984-2003. Finalmente, se presentan las conclusiones del análisis.

Within the discussion on how to implement fiscal discipline in the European Monetary Union, the adequacy of using the same fiscal rules for different Member-Countries has been challenged by some authors, calling for a temporary higher degree of fiscal flexibility in the case of small and less developed countries. We develop a model of a monetary union between two countries that may differ in (i) economic dimension; (ii) exogenous levels of productivity directly related with the quality of domestic institutions; (iii) technological knowledge stocks; (iv) Research and Development (R&D) capacity. Results arising from the model suggest the pertinence of making some exceptions to the European framework for fiscal discipline, namely concerning to expenses leading to more resources devoted to R&D activities. In particular, this would apply to measures taken by the less developed countries, possibly leading to an easier catching-up.
CHATBOTS E AUTOMAÇÃO DE MENSAGENS: IMPACTO E EFICIÊNCIA NO CONTEXTO BRASILEIRO
Authors: Canellas Lucas David
Published: February 2025

Systems based on chatbots have become progressively more popular. When properly designed and equipped with a solid knowledge base, some of these systems are able to interact with users in a way analogous to human-to-human interaction. Both the market and consumers demonstrate a positive receptivity to the use of these technologies, with a customer acceptance rate of around 40%, in addition to great predictions for the growth of the chatbot market in the coming years. What is the process involved in automating bots to exchange messages? Since, in the Brazilian context, the situation is not very different, although it is at a less advanced stage compared to the North American market, there is a significant concentration in the southeast region of the country. Therefore, the general objective is to carry out an analysis of instant messaging bots. Thus, an instant messaging bot has the ability to gather customer feedback, examine communication patterns, and modify its responses to become progressively more accurate and useful. Therefore, the adoption of chatbots is an effective approach to improving interaction and consolidating the bond with users. Robots employ natural language processing algorithms, which enable them to understand and respond to messages more similar to human interaction. Creating and customizing chatbots requires selecting the appropriate artificial intelligence platforms and tools, adapting the bot to specific company requirements, and integrating with CRM and automation systems.

O presente estudo tem o objetivo de verificar a importância do saneamento básico, que é considerado fundamental para a qualidade de vida da população, no entanto, a maioria das áreas rurais ainda carece de serviços adequados de tratamento de esgoto. Trata-se de um estudo transversal, com enfoque em demonstrar a importância das fossas biodigestoras como solução compatível para o tratamento de esgoto em áreas rurais, em especial no Ribeirão Araras, no município de Paranavaí-PR. Para isso, será realizada uma revisão bibliográfica sobre a Política Nacional de Saneamento e o uso de fossas biodigestoras como alternativa para o tratamento de esgoto em áreas rurais. Além disso, serão levantados dados sobre a eficiência desse modelo de tratamento, seus custos e impactos ambientais e culturais. Desse modo realizaremos um levantamento de campo para identificar a aceitação da população rural em relação à implantação das fossas biodigestoras e compreender como essa alternativa pode contribuir para a universalização do saneamento na região. Sendo assim, a implantação de fossas biodigestoras poderá favorecer benefícios ambientais, econômicos e culturais para as comunidades rurais, justificando assim a realização deste estudo. Os dados serão analisados qualitativamente, buscando identificar as principais vantagens e desvantagens da implantação das fossas biodigestoras nessa localidade. O estudo mostrou que as fossas biodigestoras apresentam a mesma eficiência de uma estação de tratamento convencional, constituindo uma alternativa viável e sustentável para atender a população rural que não é atendida pelo saneamento. Além disso, verificamos que a implantação dessas fossas foram bem aceitas pela comunidade local sendo estabelecidas como uma excelente alternativa para atender ao dispositivo da lei 11.445/2007 cujo objetivo é garantir a qualidade de vida e a saúde da população, promovendo ações efetivas e sustentáveis no saneamento básico no quesito universalização do saneamento.

Published: February 2025

Through advanced technologies and innovations, changes have accelerated in healthcare rapidly, profoundly, efficiently, person-orientated, and access to patients. Of all the most important are the changes in healthcare, changes to keep pace with new complexity in society as changes in AI, ML, EHR, and telemedicine. This paper explores how technological innovations shift the landscape of patient care by promoting increased diagnostic accuracy, improved treatment outcomes, greater efficiency in managing operations, and making patients participate in the healthcare process. Some of the major areas where healthcare technology implementation happens are examined in this study, including data analytics, mobile health solutions, and remote monitoring systems. It also addresses issues concerning the problems in the implementation of these technologies. These barriers include data privacy issues and digital divides, and healthcare providers need to accept these new systems. Thus, the overall objective of this paper is to explain all possible aspects, such as the strengths and limitations of these innovations that emphasize a balanced approach to improving technology supporting patient care but not compromise over quality, equity, or patient safety. Lastly, the study presents an achievable future where collaborative interaction with technology is going to assist healthcare systems to perform services for all their patients in an efficient, accurate, and increasingly manner.

Published: February 2025

Alzheimer’s disease has been a serious public health issue that needs prompt and precise diagnosis in the management and treatment phase. The following paper presents a machine learning system mainly engineered to classify AD via neuroimaging and clinical features comprising air time1, disp index1, gmrt in air1, max x extension1, and max y extension1 to detect subtle patterns possibly indicative of Alzheimer’s pathology. Systematic data preprocessing and visualization techniques, such as correlation heatmaps and 3D scatter plots, reflect complicated interdependencies in AD progression. The classifiers utilized include Cat Boost and Light GBM for AD and healthy controls, and AdaBoost for mild cognitive impairment. Model performance is measured by accuracy, precision, recall, F1 score, classification reports, and confusion matrices, helping to discover model strengths and weaknesses. A learning curve showed that the models are general and flexible enough for practical circumstances. The work shows that machine learning can integrate multi-modal data modalities into AD diagnosis. Thus, it improves diagnostic accuracy and enables personalized treatment strategies, improving patient outcomes and supporting cutting-edge neurodegenerative disease clinical decisions.
“World Health Organization (WHO) and European Food Safety Authority (EFSA) risk evaluations”: Basis of TDIs and tolerable drinking water levels derived by Germany, EFSA, ECHA, and WHO
Authors: Dietrich Daniel R. , Greim Helmut
Published: February 2025

Various national and international agencies have evaluated the available information on per- and polyfluoroalkyl substances (PFAS) to determine no observed adverse effect levels (NOAELs), tolerable daily intake (TDIs) and drinking water standards. In Europe, this includes the German drinking water commission,1 the European Food Safety Agency (EFSA),2 European Chemicals Agency (ECHA)3 as well as the World Health Organization (WHO).4 Health-based guidance values e.g. tolerable weekly intake (TWI) appear to largely depend on what information was considered to be relevant and robust. For both, WHO and EFSA, there is the impression that too little consideration was given to the statistical, biological and experimental design robustness of the data sets that were employed.

Many lettuce plants are grown hydroponically because they produce better quality.The problem with hydroponic systems is that the plant roots are submerged in the nutrient solution, therefore it will  rot easily due to lack of oxygen in the root area. To overcome this problem, hydroponics with microbubble technology is applied. This research aims to determine the performance of the ventury dual nozzle in producing microbubbles and its effect on the growth and productivity of lettuce plants. This research was carried out by assembling a hydroponic system equipped with a ventury model aerator, measuring bubble characteristics using the image processing method and analyzing plant parameters using variance analysis. Ventury nozzle with a pressure of 260 KPa produces microbubbles measuring between 200 - 300 m and a spray range of 6.13 cm with a resistance of around 3.2-4.6 seconds. The use of a ventury nozzle model aerator increases dissolved oxygen and distributes it evenly in the hydroponic nutrient solution, thereby increasing the growth and yield of lettuce plants.
