RESUMO

Introdução: Na medida em que envelhecemos os lábios estreitam-se, ocasionando perda de volume e contorno e como forma de minimizar este efeito fisiológico o preenchimento labial de escolha utilizado é o ácido hialurônico. É possível perceber efeitos adversos advindos do emprego deste material, e pelo fato da informação ao paciente ser assegurada pelo Código de Defesa do Consumidor e pelo fato da necessidade dos Cirurgiões-Dentistas terem de esclarecer seus pacientes, o Termo de Consentimento Livre e Esclarecido tornase necessário. Objetivo: identificar, por meio de aplicação de questionário, a percepção de profissionais que trabalham com Harmonização Orofacial em relação a necessidade do emprego do Termo de Consentimento Livre e Esclarecido (TCLE). O questionário apresentou 6 perguntas objetivas, que foram disponibilizadas na plataforma Google Forms®. Material e Método: os dados obtidos foram tabulados em uma planilha eletrônica do programa Microsoft Excel e após analisados descritivamente através de tabelas de frequência, porcentagens e gráficos estatísticos. Resultados: dentre os entrevistados foi constatado que a maioria, 87,5% dos especialistas em Harmonização Orofacial realizam o procedimento de preenchimento labial em sua rotina clínica, e 12,5% não. Conclusão: no presente estudo identificamos que os especialistas realizam o emprego do TCLE, em sua maioria, porém, alguns destes ainda negligenciam o seu uso(AU)

RESUMO

The problem of formulating thermodynamics in a relativistic scenario remains unresolved, although many proposals exist in the literature. The challenge arises due to the intrinsic dynamic structure of spacetime as established by the general theory of relativity. With the discovery of the physical nature of information, which underpins Landauer's principle, we believe that information theory should play a role in understanding this problem. In this work, we contribute to this endeavour by considering a relativistic communication task between two partners, Alice and Bob, in a general Lorentzian spacetime. We then assume that the receiver, Bob, reversibly operates a local heat engine powered by information, and seek to determine the maximum amount of work he can extract from this device. As Bob cannot extract work for free, by applying both Landauer's principle and the second law of thermodynamics, we establish a bound on the energy Bob must spend to acquire the information in the first place. This bound is a function of the spacetime metric and the properties of the communication channel.

RESUMO

Scale-free brain activity, linked with learning, the integration of different time scales, and the formation of mental models, is correlated with a metastable cognitive basis. The spectral slope, a key aspect of scale-free dynamics, was proposed as a potential indicator to distinguish between different sleep stages. Studies suggest that brain networks maintain a consistent scale-free structure across wakefulness, anesthesia, and recovery. Although differences in anesthetic sensitivity between the sexes are recognized, these variations are not evident in clinical electroencephalographic recordings of the cortex. Recently, changes in the slope of the power law exponent of neural activity were found to correlate with changes in Rényi entropy, an extended concept of Shannon's information entropy. These findings establish quantifiers as a promising tool for the study of scale-free dynamics in the brain. Our study presents a novel visual representation called the Rényi entropy-complexity causality space, which encapsulates complexity, permutation entropy, and the Rényi parameter q. The main goal of this study is to define this space for classical dynamical systems within theoretical bounds. In addition, the study aims to investigate how well different time series mimicking scale-free activity can be discriminated. Finally, this tool is used to detect dynamic features in intracranial electroencephalography (iEEG) signals. To achieve these goals, the study implementse the Bandt and Pompe method for ordinal patterns. In this process, each signal is associated with a probability distribution, and the causal measures of Rényi entropy and complexity are computed based on the parameter q. This method is a valuable tool for analyzing simulated time series. It effectively distinguishes elements of correlated noise and provides a straightforward means of examining differences in behaviors, characteristics, and classifications. For the iEEG experimental data, the REM state showed a greater number of significant sex-based differences, while the supramarginal gyrus region showed the most variation across different modes and analyzes. Exploring scale-free brain activity with this framework could provide valuable insights into cognition and neurological disorders. The results may have implications for understanding differences in brain function between the sexes and their possible relevance to neurological disorders.

RESUMO

Small-world networks and scale-free networks are well-known theoretical models within the realm of complex graphs. These models exhibit "low" average shortest-path length; however, key distinctions are observed in their degree distributions and average clustering coefficients: in small-world networks, the degree distribution is bell-shaped and the clustering is "high"; in scale-free networks, the degree distribution follows a power law and the clustering is "low". Here, a model for generating scale-free graphs with "high" clustering is numerically explored, since these features are concurrently identified in networks representing social interactions. In this model, the values of average degree and exponent of the power-law degree distribution are both adjustable, and spatial limitations in the creation of links are taken into account. Several topological metrics are calculated and compared for computer-generated graphs. Unexpectedly, the numerical experiments show that, by varying the model parameters, a transition from a power-law to a bell-shaped degree distribution can occur. Also, in these graphs, the degree distribution is most accurately characterized by a pure power-law for values of the exponent typically found in real-world networks.

RESUMO

In order to comprehend and enhance models that describes various brain regions it is important to study the dynamics of trained recurrent neural networks. Including Dale's law in such models usually presents several challenges. However, this is an important aspect that allows computational models to better capture the characteristics of the brain. Here we present a framework to train networks using such constraint. Then we have used it to train them in simple decision making tasks. We characterized the eigenvalue distributions of the recurrent weight matrices of such networks. Interestingly, we discovered that the non-dominant eigenvalues of the recurrent weight matrix are distributed in a circle with a radius less than 1 for those whose initial condition before training was random normal and in a ring for those whose initial condition was random orthogonal. In both cases, the radius does not depend on the fraction of excitatory and inhibitory units nor the size of the network. Diminution of the radius, compared to networks trained without the constraint, has implications on the activity and dynamics that we discussed here.

RESUMO

Objetivo: compreender a participação da IA nos diagnósticos da saúde moderna e definir limites para sua aplicação. Metodologia: Revisão integrativa da literatura. A busca dos estudos se deu nas bases de dados LILACS, MEDLINE e SCIELO e foram selecionados artigos científicos, sem recorte temporal e de idioma. Resultados: A inteligência artificial impacta a medicina em três níveis: otimiza a interpretação de imagens para os médicos, aprimora o fluxo de trabalho reduzindo potenciais erros para os sistemas de saúde e capacita os pacientes a processarem seus próprios dados para promover a saúde. Contudo, é necessária atenção aos dados gerados, pois podem desencadear erros em cascata e expor informações sensíveis dos usuários do sistema de saúde. Conclusão: Atribuir à IA a responsabilidade de escolhas e funções desempenhadas por humanos é intrinsecamente perigoso, apesar de sua contribuição inegável nos processos diagnósticos. Sugere-se a realização de pesquisas robustas para compreender plenamente o impacto dessa nova era tecnológica proporcionada pela IA na área da saúde.


Objective: To understand the role of AI in modern healthcare diagnostics and define boundaries for its application. Methodology:Integrative literature review.

RESUMO

Ethical considerations regarding our treatment of animals have gained strength, leading to legislation and a societal focus across various disciplines. This is a subject of study within curricula related to agri-food sciences. The aim was to determine the perceptions of agronomy university students concerning animal welfare in livestock production systems. A survey was conducted to encompass various aspects, from participants' sociodemographic attributes to their attitudes and behaviors regarding animal welfare and the consumption of animal products. Statistical analysis, performed using R software, delved into the associations between participants' characteristics and their perspectives on the ethical, bioethical, and legal dimensions of animal welfare. Associations between demographic factors and ethical viewpoints among students were identified. Gender differences emerged in animal treatment perceptions, while rural and urban environments impacted perspectives on various animals. Bioethical considerations revealed distinctive disparities based on gender and education in concerns regarding animal welfare, value perceptions, evaluations of animal behaviors, and opinions on animal research. It is crucial to distinguish between animal welfare and the ethical considerations arising from coexisting with sentient beings capable of experiencing suffering. Ethical theories provide a lens through which we perceive our obligations toward animals. The responsibility to ensure animal welfare is firmly rooted in recognizing that animals, like humans, experience pain and physical suffering. Consequently, actions causing unjustified suffering or mistreatment, particularly for entertainment purposes, are considered morally unacceptable.

RESUMO

BACKGROUND: This study explores the impacts of attacks perpetrated in the context of armed conflict, to female health workers in three Colombian territories. METHODS: We conducted a document review of the reports and databases of the Colombian Truth Commission, 17 in-depth semi-structured interviews with experts on the national and regional armed conflict and the medical mission, and 26 female health workers who were victims of attacks. RESULTS: Experts and female health workers reported attacks to health activities, facilities, equipment, and personnel, including attacks to traditional doctors belonging to indigenous communities. The most frequent attacks were threats and retention of health personnel; theft of supplies and medicines; damage and use of infrastructure and means of transport for purposes other than health care; and hinderance of health service provision. The attacks occurred in a framework of structural violence that intersects with poverty, racism, and gender bias. The impacts of these attacks include gender-based violence, significant disruption of the lives of health workers, and physical, emotional, psychological, social, and economic effects on the victims and their families. The government response to protect victims and populations has been absent or insufficient. CONCLUSIONS: Attacks to health care were reported in all the studied territories obstructing adequate health care. Impacts of these attacks affect negatively the professional and personal life of the workers and are aggravated by structural violence and absent or little institutional response.
