Detecting Structure of Complex Network by Quantum Bosonic Dynamics

We introduce a non-interacting boson model to investigate topological structure of complex networks in the present paper. By exactly solving this model, we show that it provides a powerful analytical tool in uncovering the important properties of real-world networks. We find that the ground state degeneracy of this model is equal to the number of connected components in the network and the square of coefficients in the expansion of ground state gives the averaged time for a random walker spending at each node in the infinite time limit. Furthermore, the first excited state appears always on its largest connected component. To show usefulness of this approach in practice, we carry on also numerical simulations on some concrete complex networks. Our results are completely consistent with the previous conclusions derived by graph theory methods.Comment: 4 pages, 3 figure

Is severe early childhood caries predictive of caries and fluorosis in permanent teeth? Ten-year follow-up

Abstract Introduction Severe early childhood caries is defined as the presence of any sign of decay in children younger than three years. Objective This retrospective longitudinal observational study investigated caries and fluorosis in children with S-ECC from a city with fluoridated water. Material and method We included children under the age of three years who followed a maternal and child dental care program between the years of 1997 and 2003. The children were divided into 2 groups: group 1 (S-ECC) and group 2 (no caries). Guardians were contacted by telephone or mail. Caregivers completed questionnaire on socio-demographic and behavioral variables. The clinical dental examinations were performed in a dental clinic to assess caries experience and dental fluorosis. Multiple linear regression was used to determine factors associated with DMFT, and multivariate analysis by multiple logistic regression was used to determine the possible independent factors associated with the occurrence of fluorosis. Result The sample consisted of 126 patients aged 8-12 years, of whom 52.4% were male. The presence of S-ECC increased the DMFT by an average of 0.84 (p = 0.02). Both the frequency of tooth brushing and the use of standard toothpaste were protective factors from the development of caries in the permanent dentition (p <0.05). Parents who reported that their children refused to brush their teeth had 70% less chance of developing fluorosis (p = 0.02). Conclusion The presence of S-ECC was a risk factor for the development of caries in the permanent dentition, but not for the development of fluorosis

Perfil epidemiológico dos casos de síndrome respiratória aguda grave no estado de Minas Gerais, Brasil, 2020 a 2021: Vigil Sanit Debate, Rio de Janeiro, 2023, v.11: e02062 | Publicado em: 03/08/2023

Introduction: The increase in the number of cases of severe acute respiratory syndrome (SARS) associated with Sars-CoV-2 has given rise to one of the largest public health emergencies in the world. Objective: To evaluate the epidemiological profile of SARS in the state of Minas Gerais, from 2020 to 2021. Method: A cross-sectional, descriptive,retrospective, and qualitative-quantitative research was carried out. Data were collected from the SIVEP-Gripe system and the COVID-19 Case Monitoring Panel, for the years from 2020 to 2021. The variables analyzed were: total COVID-19 cases, total SARS and SARS due to COVID-19, age, sex, race, final classification and final evolution. Results: The state had 315,726 SARS cases, and of these, 58.6% were caused by Sars-CoV-2. Most individuals who presented SARS were male, aged 60 years and over and brown. Among the SARS cases, 23.3% evolved to death, and of these, 77.6% were caused by COVID-19. The regions of Uberlândia, Belo Horizonte, Coronel Fabriciano, Patos de Minas, Uberaba, Ituiutaba, Leopoldina, Governador Valadares and Juiz de Fora had the highest occurrences of SARS/inhabitants. The regionals from São João del-Rei, Teófilo Otoni, Passos and Uberaba stood out for having a high lethality rate of patients who had SARS due to COVID-19. Conclusion: The distribution of reported SARS cases and deaths in Minas Gerais was heterogeneous, with a greater number of cases in municipalities with higher population density. The questions listed in this research pointed out the deficiencies and weaknesses in the response capacities to face the pandemic, which indicates the need for decentralizing and restructuring the health system of several municipalities in the state.Introdução: O aumento do número de casos de síndrome respiratória aguda grave (SRAG) associado ao SARS-CoV-2 originou uma das maiores emergências mundiais de saúde pública. Objetivo: Avaliar o perfil epidemiológico da SRAG no estado de Minas Gerais, durante 2020 e 2021. Método: Realizou-se pesquisa transversal, descritiva, retrospectiva e qualiquantitativa. Os dados foram coletados do sistema SIVEP-Gripe e do Painel de Monitoramento dos Casos de COVID-19, dos anos de 2020 e 2021. As variáveis analisadas foram: total de casos de COVID-19, total de SRAG e SRAG por COVID-19, idade, sexo, raça, classificação final e evolução final. Resultados: O estado apresentou 315.726 casos de SRAG e, destes, 58,6% foram causados pelo SARS-CoV-2. A maioria dos indivíduos que apresentou SRAG eram do sexo masculino, faixa etária de acima dos 60 anos e raça parda. Dentre os casos de SRAG, 23,3% evoluíram para óbito, e destes 77,6% tinham como causa a COVID-19. As regionais de Uberlândia, Belo Horizonte, Coronel Fabriciano, Patos de Minas, Uberaba, Ituiutaba, Leopoldina, Governador Valadares e Juiz de Fora apresentaram as maiores ocorrências de SRAG/habitantes. As regionais São João del-Rei, Teófilo Otoni, Passos e Uberaba destacaram-se por apresentar elevada taxa de letalidade dos pacientes que apresentaram SRAG por COVID-19. Conclusões: A distribuição dos casos e óbitos notificados de SRAG em Minas Gerais foi heterogênea, com número maior de casos em municípios com maior densidade demográfica. As questões elencadas nesta pesquisa apontaram as deficiências e fragilidades nas capacidades de resposta ao enfrentamento da pandemia, o que indica a necessidade de descentralização e reestruturação do sistema de saúde de diversos municípios do estado

A Formação de Psicólogas (os) para a Atuação nos Contextos Rurais: a experiência da Residência Multiprofissional em Saúde do Campo.

O distanciamento da Psicologia das demandas das populações do campo é um fato histórico. Mesmo com a sua inserção no contexto das políticas públicas e reorientação da formação a partir das novas diretrizes curriculares, o olhar dessa ciência e profissão manteve-se restrito às demandas do contexto urbano. Em 2011, com a aprovação da Política Nacional de Saúde Integral das Populações do Campo, da Floresta e das Águas (PNSIPCFA), as diferentes profissões da Saúde ganham um marco legal de estímulo à formação de profissionais sensíveis às especificidades dessas populações. A primeira Residência Multiprofissional em Saúde da Família com ênfase na Saúde da População do Campo (RMSC) surge, então, com a missão de formar profissionais de saúde a partir das necessidades e especificidades das populações do campo. O objetivo desse trabalho é refletir sobre a experiência da formação e atuação das (os) residentes de Psicologia inseridas (os) nesse programa, entendendo que a inserção da Psicologia nessa experiência pioneira lança novos olhares para a consolidação tanto da Psicologia Rural, quanto da PNSIPCFA no país.  

Evaluation of Vitamin D Isolated or Associated with Teriparatide in Peri-Implant Bone Repair in Tibia of Orchiectomized Rats

(1) Background: The objective of this study was to evaluate the morphometry of peri-implant bone tissue in orchiectomized rats, treated with vitamin D isolated or associated with teriparatide. (2) Methods: 24 rats were divided into 4 groups: ORQ&mdash;orchiectomy, without drug treatment, ORQ+D&mdash;orchiectomy, treated with vitamin D, ORQTERI&mdash;orchiectomy, treated with teriparatide and ORQTERI+D&mdash;orchiectomy, treated with teriparatide + vitamin D. Each animal received an implant in the tibial metaphysis. Euthanasia occurred 60 days after implant surgery. Computed microtomography (micro-CT) was performed to evaluate the parameters of volume and percentage of bone volume (BV, BV/TV), trabecular thickness (Tb.Th), number and separation of trabeculae (Tb.N, Tb.Sp) and percentage of total porosity (Po-tot). Data were subjected to 1-way ANOVA and Tukey post-test, with a significance level of 5%. (3) Results: For the parameters BV, BV/TV, Tb.Th, the ORQTERI+D group showed the highest values in relation to the other groups and for Po-tot, the lowest values were for ORQTERI+D. For Tb.Sp and Tb.N, there was no statistically significant difference when comparing intragroup results (p &gt; 0.05). (4) Conclusions: It was possible to conclude that treatment with vitamin D associated with teriparatide increases bone volume and improves bone quality
