ABSTRACT

Introdução: A lei de cotas (nº 12.711/2012) foi criada com o intuito de oportunizar o acesso de alunos oriundos de escolas públicas ao ensino superior. Desde então, medidas adicionais foram tomadas para garantir, não só o acesso, mas a permanência destes alunos nas universidades. Objetivo: Este estudo teve como objetivo avaliar o desempenho acadêmico dealunos cotistas e não cotistas da Faculdade de Odontologia da Universidade Federal do Pará. Metodologia: Foram coletados dados de alunos matriculados nos anos de 2020 e2021 por meio de um questionário on-line e realizada a análise de histórico acadêmico dos voluntários. A análise dos dados foi realizada com software Jamovi versão 1.6.23, utilizando os testesQui-quadrado, t de Student para amostras independentes e análise de regressão linear multivariada. Em todas as análises foi adotado o nível de significância de 0,05. Resultados: Com uma taxa de resposta de 39,92% (n=200), os resultados demonstraram haver um melhor desempenho acadêmico para o grupo não-cotista no que se refere ao Coeficiente de Rendimento Geral (p=0,001). Além disso, alunos do grupo cotista enfrentam mais dificuldades quando comparados aos não-cotistas (p<0,0001). Na análise múltipla verificou-se que juntas, forma de ingresso (cotista ou não), o enfrentamento de dificuldades, recebimento de auxílios e atividades fora da Faculdade explicam quase 10% da variável Coeficiente de Rendimento Geral (R² = 0,098). Conclusões: A complexidade da comparação sugere a possibilidade de múltiplas causas, entre elas o fator socioeconômico e outras dificuldades experienciadas. Entender e atuar nestas causas é de fundamental importância para a construção de uma universidade inclusiva de qualidade (AU).


Introduction:The quota law (nº 12.711/2012) was created with the objective of providing opportunities for students from public schools to enter federal universities. Since then, additional measures have been taken to ensure not only the access, but the permanence of these students in universities. Objectives:This study aimed to assess the academic performance of quota students and non-quota students at the Faculty of Dentistry of the Federal University of Pará. Methods:Data were collected from students enrolled in the years 2020 and 2021 through an online questionnaire and the academic history of the volunteers was analyzed. Data analysis was performed with Jamovi software version 1.6.23, using the chi-square test, Student's t test for independent samples, and multivariate linear regression analysis. In all analyses, a significance level of 0.05 was adopted. Results:With a response rate of 39.92% (n=200), the results showed a better academic performance for the non-quotastudents with regard to the General PerformanceCoefficient (p=0.001). In addition, quota students face more difficulties when compared to non-quota students (p<0.0001). In the multiple analysis, it was found that the admission modality (quota students or non-quota students), facing difficulties, receiving aid, and activities outside the University explained together almost 10% of the General Performance Coefficient variable (R² = 0.098). Conclusion:The complexity of the comparison suggests the possibility of multiple causes, including the socioeconomic factor and other difficulties experienced. Understanding and acting on these causes is of fundamental importance for the construction of a quality inclusive university (AU).

ABSTRACT

Introduction: Community Health Workers (CHW) are a critical resource for outbreak preparedness and response. However, CHWs´ ability to respond to outbreaks depends on their accurate knowledge of the disease and proper adoption of disease prevention practices. We explored knowledge and practices related to outbreaks in general, and COVID-19 among CHWs in Rwanda. Methods: this cross-sectional multimethod study used stratified simple random sampling to recruit three cadres of CHWs (agents de santé maternelle, female Binomes, and male Binomes ) from three rural Rwandan districts. We used telephone-based data collection to administer quantitative surveys (N=292) and qualitative interviews (N=24) in September 2020. We calculated descriptive statistics and conducted thematic analysis of qualitative data. We assessed for associations between general outbreak-related knowledge and receipt of training using Chi-square tests and between COVID-19 related knowledge and CHW characteristics and adoption of prevention methods using linear regression models. Results: only 56.2% of CHWs had received training on any health topic in 12 months prior to COVID-19 pandemic and only 19.2% had specifically received training on outbreak preparedness. Almost all CHWs reported preventing COVID-19 by wearing facemasks (98%), washing hands (95%), and social distancing in crowds (89%) with fewer reporting staying at home (50%), sneezing or coughing into an elbow (38%) or using hand sanitizer (18%). Almost all CHWs in our study knew that COVID-19 transmit through respiratory droplets (98%) and by infected surfaces (98%) and that asymptomatic spread is possible (91%). However, fewer than half of community health workers correctly affirmed that children were at low risk of becoming severely ill (48%) and only 32% correctly rejected the misconception that everyone with COVID-19 would become severely ill. There was no association between COVID-19-related knowledge and adoption of COVID-19 preventative practices. Qualitative findings suggested that while CHWs possessed lots of correct information about COVID-19 and reported good adherence to COVID-19 prevention practices, they also commonly held misconceptions that over-exaggerated the dangers of COVID-19. Conclusion: gaps in knowledge, training, and access to information point to a need for additional investment in supervision and credible informational systems to support CHWs.

ABSTRACT

The aims of the current study were to evaluate the psychometric properties of a short version of the Five Facet Mindfulness Questionnaire (FFMQ-SF-BR) and verify if the addition of wording mechanisms (positive or negative) contributes to the fit of the shortened Brazilian Portuguese version of the FFMQ. Four hundred eight participants answered self-report measurements. Structural equation modelling was employed for both objectives. Adequate model fit was found for the 5-factor FFMQ-SF-BR model, with significant improvements arising from the addition of wording mechanism effects. No evidences of differential item functioning and population heterogeneity were found. Bifactor analysis showed that latent traces are preferred overusing raw sum scores. The FFMQ-SF-BR is suitable to measure mindfulness in the Brazilian population and has the benefits of decreasing data collection length without losing content coverage. (AU)


O presente estudo objetivou avaliar as propriedades psicométricas de uma versão curta em português do Questionário das Cinco Facetas de Mindfulness (FFMQ-SF-BR) e verificar se a adição de mecanismos de formulação dos itens (positivos ou negativos) contribui para o ajuste do modelo em cinco fatores. Quatrocentos e oito participantes preencheram instrumentos de autorrelato. Modelagem de equações estruturais foi aplicada em ambos os objetivos. Índices adequados de ajuste foram encontrados para o modelo em cinco fatores, com melhorias significativas advindas da adição dos mecanismos de formulação dos itens. Não foram encontradas evidências de funcionamento diferencial dos itens ou heterogeneidade populacional. A análise de um modelo bifator demonstrou que valores de traços latentes são preferíveis à soma da pontuação. A FFMQ-SF-BR é adequada para mensurar mindfulness na população brasileira, com os benefícios de diminuir o tempo de coleta sem perda de conteúdo. (AU)

ABSTRACT

Introduction Intracranial aneurysm (IA) is a major healthcare concern. The use of statin to reduce serum cholesterol has shown evidence to reduce cardiovascular risk in various diseases, but the impact on IA has not been described. This study aims to determine whether statin use, and serum cholesterol levels interfere with outcomes after IA event. Methods A cohort of patients with IA was analyzed. Patients social and demographics data were collected.Modified Rankin scale (mRS) score after 6months of follow-up was the endpoint. The data regarding statins use, presence or not of atherosclerotic plaque in radiological images and serum cholesterol of 35 patients were included in our study. Linear regression models were used to determine the influence of those 6 variables in the clinical outcome. Results The prevalence of atherosclerotic plaque, high cholesterol and use of statins was 34.3%, 48.5%, and 14.2%, respectively. Statins and serum cholesterol did not impact the overall outcome,measured by mRS after 6 months (p>0.05), but did show different tendencies when separated by IA rupture status. Serum cholesterol shows na important association with rupture of aneurysm (p»0.0382). High cholesterol and use of statins show a tendency for worse outcome with ruptured aneurysm, and the opposite is true for unruptured aneurysm. The presence of atherosclerotic plaques was not related with worse outcomes. Conclusions Multiple and opposite mechanisms might be involved in the pathophysiology of IA. Ruptured aneurysms are associated with higher levels of serum cholesterol. Serum cholesterol and statins use were not correlated with worse outcomes, but further studies are important to clarify these relationships.


Introdução Aneurisma intracranial (AI) é uma grande preocupação para a saúde. Evidências apontam que o uso de estatina para reduzir o colesterol sérico diminui o risco cardiovascular em diversas doenças, mas o impacto em AI ainda não foi descrito. Este estudo almeja determinar se o uso de estatina e o nível sérico de colesterol interferem no desfecho clínico após a ocorrência de AIs. Métodos Uma coorte de pacientes com AI foi analisada. Os dados sociodemográficos dos pacientes foram coletados. Ao final de 6 meses de acompanhamento, aplicou-se a escala modificada de Rankin (mRS). Os dados sobre uso de estatina, existência de placa aterosclerótica em imagens radiológicas, e colesterol sérico de 35 pacientes foram incluídos no estudo. Modelos de regressão linear foram usados para determinar a influência dessas 6 variáveis nos desfechos clínicos. Resultados A prevalência de placa aterosclerótica, colesterol elevado, e uso de estatina foram respectivamente 34,3%, 48,5% e 14,2%. Estatina e colesterol sérico não impactaram nos desfechos medidos pela mRS em 6 meses (p > 0,05), mas mostraram diferentes tendências quando separados pelo estado de ruptura do AI. Colesterol sérico apresenta uma importante associação com ruptura de aneurisma (p » 0,0382). Colesterol elevado e uso de estatinas representam uma tendência a piores desfechos para aneurismas rompidos, e o oposto é verdade para os não rompidos. A presença de placa aterosclerótica não está relacionada com piores resultados. Conclusões Mecanismos múltiplos e opostos podem estar envolvidos na patofisio logia do AI. Aneurismas rompidos estão associados com maiores níveis de colesterol sérico. Colesterol sérico e estatinas não foram correlacionados com piores desfechos, mas mais estudos são importantes para clarificar a relação entre esses fatores

ABSTRACT

Resumo A investigação analisou a tendência da mortalidade por HIV/Aids segundo características sociodemográficas nos estados brasileiros entre 2000 e 2018. Estudo ecológico de série temporal das taxas padronizadas de mortalidade por Aids geral, por sexo, faixa etária, estado civil e raça/cor. Foi utilizado o modelo linear generalizado de Prais-Winsten. Os resultados do estudo evidenciaram que os estados com as maiores taxas foram Rio Grande do Sul, Rio de Janeiro, São Paulo e Santa Catarina. A tendência foi crescente nas regiões Norte e Nordeste. Os homens tiveram taxas mais elevadas quando comparados às mulheres e à população geral. Quanto às faixas etárias, as mais avançadas mostraram tendência a crescimento. A análise de acordo com o estado civil evidenciou taxas mais elevadas entre os não casados e tendência a crescimento concentrada nesta população. De acordo com raça/cor, identificou-se que os negros apresentaram maiores taxas, exceto no Paraná, e a tendência foi majoritariamente crescente. A mortalidade por HIV/Aids apresenta tendências distintas segundo as características sociodemográficas, verificando-se necessidade de ações de prevenção e cuidado aos homens, adultos, idosos, não casados e negros em vista de mudança no perfil da mortalidade.


Abstract This investigation analyzed the trend of HIV/AIDS mortality by sociodemographic characteristics in the Brazilian states from 2000 to 2018. This is an ecological study of time-series of standardized rates of mortality from AIDS overall, by gender, age group, marital status, and ethnicity/skin color, employing the Prais-Winsten generalized linear model. The results showed that the states with the highest rates were Rio Grande do Sul, Rio de Janeiro, São Paulo, and Santa Catarina. The trend was increasing in the North and Northeast. Men had higher rates than women and the general population. The most advanced age groups showed a growing trend. The analysis by marital status showed higher and growing rates among the unmarried. Blacks had higher rates, except for Paraná, with a mainly increasing trend. Mortality due to HIV/AIDS had different trends by sociodemographic characteristics, with a need for preventive and care actions for men, adults, older adults, unmarried, and black people due to the change in the mortality profile.

ABSTRACT

Resumo Estudo ecológico que analisa a tendência e a distribuição espaço-temporal dos casos novos de tuberculose (TB) que abandonaram o tratamento no Brasil, notificados no Sistema de Informação de Agravos de Notificação no período de 2012 a 2018. Para o estudo da tendência, utilizou-se o modelo de regressão linear generalizada de Prais-Winsten, e para a análise espacial os índices global e local de Moran. A média e a mediana da proporção de abandono do tratamento da TB no Brasil foram de 10,4%. As maiores médias do indicador se concentraram nas regiões Sudeste (10,78 ± 1,38), Sul (10,70 ± 2,94) e Norte (10,35 ± 1,13), e nos estados de Rondônia (14,35 ± 2,34), Rio Grande do Sul (13,60 ± 4,23) e Rio de Janeiro (12,64 ± 1,73). Apenas Acre e Piauí apresentaram esse indicador abaixo de 5%. No Brasil, houve tendência de estabilidade na proporção do abandono do tratamento da TB, decréscimo nas regiões Norte, Nordeste e Sul, e somente no Distrito Federal houve crescimento. Verificou-se distribuição heterogênea e não aleatória, com cinco capitais compondo o cluster de alto-risco. Concluímos que a proporção de abandono do tratamento da TB no Brasil encontra-se acima do aceitável e que a identificação de áreas de alto risco pode contribuir para a elaboração e fortalecimento de ações de controle mais específicas.


Abstract Ecological study that analyzes the trend and the spatiotemporal distribution of new cases of tuberculosis (TB) that abandoned treatment in Brazil, notified in the Notifiable Diseases Information System, in the period from 2012 to 2018. For the study of the trend used the Prais-Winsten generalized linear regression model was used and the Moran Global and Local indices for spatial analysis. The mean and median proportion of TB treatment dropout in Brazil was 10.4%. The highest averages of the indicator were concentrated in the Southeast (10.78 ± 1.38), South (10.70 ± 2.94) and North (10.35 ± 1.13), and; in the states of Rondônia (14.35 ± 2.34), Rio Grande do Sul (13.60 ± 4.23) and Rio de Janeiro (12.64 ± 1.73), only Acre and Piauí showed this indicator below 5%. In Brazil, there was a tendency towards stability in the proportion of abandonment of TB treatment, a decrease in the North, Northeast and South regions and only in the Federal District there was growth. There was a heterogeneous and non-random distribution, with five capitals comprising the High-Risk cluster. We conclude that the proportion of TB treatment abandonment in Brazil is above what is acceptable and that the identification of high-risk areas can contribute to the elaboration and strengthening of more specific control actions.

ABSTRACT

This study aimed to evaluate smartphone addiction, sleep quality, quality of life and depression among dental students before and during the first wave COVID-19 pandemic lockdown and explore how smartphone addiction influences the other variables. 57 dental students answered the smartphone addiction inventory, Pittsburg sleep quality index, WHOQOL-bref and research diagnosis criteria for temporomandibular disorders axis II questionnaires before and during lockdown. Statistical analysis was conducted using Wilcoxon test, Mann-Whitney U test, Spearman tests and linear regression models considering the smartphone addiction inventory total score as the independent variable. The high mean scores on smartphone addiction on both times are remarkable. The smartphoneaddictionprevalence was also high on both times (68.66% and 71.92% respectively). Overall sleep quality improved. However, there was no significant change on overall smartphone addiction, quality of life and depression grade during lockdown. Tolerance using smartphones increased during lockdown, especially for women. Smartphone addiction showed negative correlation to quality of life and positive correlation to depression, subjective sleep quality and sleep medication use. Smartphone addiction was apredictor to total WHOQOL-bref score, all WHOQOL-bref domains, sleep medication use and to depression on both times, before and during lockdown. Smartphone addiction was directly affecting quality of life. Despite the growing smartphone use among university students due to the pandemic restrictions, this study showed that the overall smartphone addiction, quality of life and depression grade were not influenced by the lockdown restrictions. However, it was observed an improvement on sleep quality during this period among dental students (AU).


O objetivo deste estudo foi avaliar o vício emsmartphones, qualidade de vida, qualidade de sono e depressão em estudantes de odontologia antes e durante a quarentena daprimeira onda da pandemia por COVID-19. 57 estudantes de odontologia responderam nos dois tempos os questionários validados:smartphone addiction inventory, índice de qualidade de sono de Pittsburg, WHOQOL-bref e critérios para diagnóstico em pesquisa dasdisfunções temporomandibulares eixo II. Foram realizados os testes estatísticos: Wilcoxon, Mann-Whitney U, Spearman e regressões lineares considerando o total do smartphone addiction inventorycomo variável independente. A prevalência de vício em smartphonesfoi elevada nos dois tempos (68.66% e 71.92% respectivamente). Durante a quarentena a qualidade de sono melhorou e não houve diferença estatisticamente significativa no vício em smartphones, qualidade de vida nem depressão. A tolerância no uso dossmartphonesaumentou, especialmente entre as mulheres. O vício em smartphonesapresentou correlação negativa com qualidade de vida e positiva com a depressão, qualidade subjetiva do sono e necessidade de medicação hipnótica. O vício em smartphonesfoi preditor para todos os domínios do WHOQOL-bref e seu escore total, para o uso de medicação e depressão em ambos os tempos. O vício em smartphonesfoi muito elevado nos dois tempos afetando a qualidade de vida dos estudantes. Apesar do aumento do uso desmartphonesem virtude das restrições impostas pela pandemia, esse estudo mostrou que o vício em smartphones, qualidade de vida e depressão não foram influenciados pela quarentena. Entretanto, foi observada melhora na qualidade de sono durante esse período (AU).

ABSTRACT

Objetivo: Determinar los momentos de fuerza del haz superficial del masetero (SMH) obtenidos por modelos lineal y vectorial. Métodos: Investigación comparati-va in silico. Se obtuvo la fuerza del SMH con dinamó-metro en 12 pacientes varones adultos jóvenes para calcular el momento de la fuerza y trabajo mecánico a través de simulaciones en JAVA+ con NetBeans8.2. La descomposición de la fuerza fue F.cos α(x,y) y F.cos α(x,y,z) en el modelo lineal y vectorial respectivamen-te. Los momentos de fuerza fueron comparados por ANOVA (p<0,05). Resultados: La fuerza del SMH unila-teral obtenida con dinamómetro (2,5±0,1N) no difirió significativamente del modelo lineal (2,6±0,05N), pero difirió (p<0,001) del vectorial: 1,7, 2,2, 4,2N en x,y,z (general 2,7±0,02N). El momento medio de la fuerza en el modelo vectorial fue -17,9, -15,5, +14,3N.m-2, apuntando a la inclinación mandibular en el eje lateral en dirección caudal anterior, movimiento de inclina-ción en el eje lateral en la dirección cráneo-medial, e inclinación en el eje craneal en la dirección lateral-an-terior. El modelo lineal mostró momento de fuerza de 13,5N.m-2 apuntando un movimiento traslacional en dirección caudal-craneal en el eje anterior-posterior y menor trabajo mecánico del SMH (p=0,012). Con-clusión: Los modelos vectoriales son más eficientes proporcionando datos detallados para estimar los momentos de fuerza y el trabajo mecánico del SMH, y deben incluirse en los algoritmos de cálculo utilizados por dinamómetros (AU)


Objective: to determine the moments of force exerted by the superficial masseter head (SMH) obtained through linear models and vector ones. Methods: comparative in silico research. Data of SMH force obtained with dynamometer in 12 young adult male patients was used to calculate the moment of the force and mechanical work through simulations in JAVA+ performed with NetBeans8.2. Force decomposition was F.cos α(x,y) and F.cos α(x,y,z) in the linear and vector model respectively. The moments of force were compared by ANOVA (p<0.05). Results: Dynamometrical unilateral SMH force (2.5±0.1N) did not differ significantly from the linear model (2.6±0.05N), but differed (p<0.001) from the vector model: 1.7, 2.2, 4.2N on x,y,z (overall 2.7±0.02N). The mean moment of the force in the vector model was -17.9, -15.5, +14.3N.m-2, pointing to mandible's inclination on the lateral axis in anterior-caudal direction, inclination movement on the lateral axis in the cranio-medial direction and inclination on the cranial axis in the lateral-anterior direction. The linear model showed a moment of force of 13.5N.m-2 pointing to translational motion on caudal-cranial direction on the anterior-posterior axis and lower SMH mechanical work (p=0,012). Conclusion: Vector models are more efficient to provide detailed data to estimate the moments of force and mechanical work of SMH and should be included in the calculation algorithms used by dynamometers (AU)

ABSTRACT

Aims: there is increasing awareness that for effective patient care we need more than only randomized controlled trials with groups of participants and that carefully collected single case (N = 1) data have several important advantages over traditional group-level studies. With the advance of technology, collecting relevant data from a single case is becoming easier by the day, and this offers tremendous opportunities for understanding how behaviors displayed by an individual can be influenced by one or several key variables. For example, how pain experienced influences the amount of time spent on physical exercise. Method: using publicly available observational single case data, five models are compared: a classical ordinary least squares (OLS) linear regression model; a dynamic regression model (DRM); a two-level random-intercepts model (2LRI); a continuous covariate first-order autoregressive correlation model (CAR1); and an ordinary least squares model with time trend (OLST). These models are compared in terms of overall model fit statistics, estimates of the relation between physical activity (response variable of interest) and pain (covariate of interest), and residual statistics. Results: 2LRI outperforms all other models on both overall model fit and residual statistics, and provides covariate estimates that are in between the relative extremes provided by other models. CAR1 and OLST demonstrate an almost identical performance and one that is substantially better than OLS ­ which performs worst ­ and DRM. Conclusion: for observational single case data, DRM, CAR1, OLST, and 2LRI account for the serial correlation that is typically present in single case data in somewhat different ways under somewhat different assumptions, and all perform better than OLS. Implications of these findings for observational, quasi-experimental, and experimental single case studies are discussed.


Objetivos: há uma crescente conscientização de que, para um atendimento eficaz ao paciente, precisamos de mais do que apenas ensaios clínicos randomizados com grupos de participantes e que os dados de caso único cuidadosamente coletados (N = 1) têm várias vantagens importantes sobre os estudos tradicionais em nível de grupo. Com o avanço da tecnologia, coletar dados relevantes de um único caso está se tornando mais fácil a cada dia, e isso oferece enormes oportunidades para entender como os comportamentos exibidos por um indivíduo podem ser influenciados por uma ou várias variáveis-chave. Por exemplo, como a dor experimentada influencia a quantidade de tempo gasto no exercício físico. Método: usando dados de caso único observacionais disponíveis publicamente, cinco modelos são comparados: um modelo clássico de regressão linear de mínimos quadrados ordinários (OLS); um modelo de regressão dinâmica (DRM); um modelo de interceptações aleatórias de dois níveis (2LRI); um modelo de correlação autorregressiva de primeira ordem covariável contínua (CAR1); e um modelo ordinário de mínimos quadrados com tendência temporal (OLST). Esses modelos são comparados em termos de estatísticas gerais de ajuste do modelo, estimativas da relação entre atividade física (variável de resposta de interesse) e dor (covariável de interesse) e estatísticas residuais. Resultados: o 2LRI supera todos os outros modelos tanto no ajuste geral do modelo quanto nas estatísticas residuais e fornece estimativas de covariáveis que estão entre os extremos relativos fornecidos por outros modelos. CAR1 e OLST demonstram um desempenho quase idêntico e substancialmente melhor que o OLS, que apresenta o pior desempenho, e o DRM. Conclusão: para dados observacionais de caso único, DRM, CAR1, OLST e 2LRI são responsáveis pela correlação seriada que normalmente está presente em dados de caso único de maneira um pouco diferentes sob suposições um pouco diversas, e todos têm um desempenho melhor que o OLS. Implicações dessas descobertas para estudos de caso único observacionais, quase-experimentais e experimentais são discutidas.

ABSTRACT

ABSTRACT Objective To evaluate the frequency of occupational hazards and the criteria for their prevention among Iranian dentists. Material and Methods This cross-sectional study was conducted on 187 general dentists in Kerman. The data collection tool was a questionnaire including personal information (gender, age, marital status, condition and place and years of employment, and the average of weekly working hours) and a valid and reliable questionnaire of occupational hazards, including 24 questions about occupational hazards (6 domain) and nine questions about criteria for the prevention of the risks of dentistry. The t-test, chi-square, and linear regression were used. Results 92 (49.2%) were men. The mean and standard deviation of the score of occupational hazards was 27.04±16.21 out of 96, and the criteria of prevention were 22.00±7.28 out of 36. Regression analysis showed significant correlations between single statuses, years of occupational and type of employment, weekly work hours and occupational hazards, participation in occupational injury identification courses, and hepatitis vaccination. In addition, there were significant correlations between gender, age, weekly work hours, and preventive measures. Moreover, 3.2% of dentists were in a high-risk group and 26.2% were weak in preventive measures. Conclusion A total of 32.6% of dentists are at moderate risk of occupational hazards, and 10.7% meet the prevention criteria properly. It is recommended to hold training classes to identify occupational hazards and the criteria for their prevention among dentists.

ABSTRACT

Abstract Objective: To associate the impact of oral health-related quality of life with socio-demographic determinants, self-perception, oral health conditions and access to dental treatment among homeless adults. Material and Methods: A cross-sectional study was carried out in a medium-sized Brazilian city in Minas Gerais. Socio-demographic data on the use of dental services and access to hygiene supplies for oral health were collected. Clinical aspects were collected by clinical observation using the Community Oral Health Indicator and oral health-related quality of life using the Oral Health Impact Profile (OHIP-14). Medians and interquartile distance were compared using the Mann-Whitney and Kruskal-Wallis tests. Multiple linear regression included significant variables (p<0.05) of the bivariate analysis according to each OHIP-14 domain. Results: Women had the lowest scores for the physical and social disability domains. Oral health conditions were associated with physical and psychological limitations and disability. The presence of more teeth was associated with a negative impact on the functional and physical domains, and inflamed gums, lack of need for dental prosthesis, and use of private services were associated with a greater psychological disability. Conclusion: Oral health-related quality of life of the homeless population is affected, especially in the physical and psychological aspects. Equitable and inclusive health actions aimed at this population should include oral health (AU).

ABSTRACT

O objetivo do artigo é analisar o efeito da compra direta de alimentos da agricultura familiar para alimentação escolar sobre o déficit de estatura em crianças menores de cinco anos, entre 2013 e 2017, no Brasil. O método utilizado é o estudo ecológico e longitudinal, em que a coleta de dados ocorreu em diferentes bancos de dados. A análise foi realizada por meio do teste t para amostras independentes, a fim de comparar as médias entre as variáveis déficit de estatura e compras da agricultura familiar. Além disso, uma análise multivariável foi feita por meio da regressão linear múltipla. Verificou-se uma diferença de médias na prevalência do déficit de estatura significativa entre os municípios que compraram menos de 30% e aqueles que adquiriram 30% ou mais de alimentos da agricultura familiar para alimentação escolar, com 1,47 pontos de diferença. O modelo de regressão linear mostrou que a cada ponto percentual de aumento na compra de alimentos da agricultura familiar para a alimentação escolar pelo município, haverá, em média, uma diminuição 0,55 pontos na prevalência do déficit de estatura, independentemente das demais variáveis. Assim, conclui-se que a compra de alimentos da agricultura familiar para alimentação escolar no Brasil pode contribuir para a redução da prevalência do déficit de estatura em crianças menores de cinco anos.


The objective of this work is to analyze the effect of direct purchase of food from family farms for school meals on the deficit of stature in children under 5 years of age between 2013 and 2017 in Brazil. Method: Ecological and longitudinal study in which data collection occurred in different databases. The analysis was performed using the t-test for independent samples in order to compare the means between the variables stature deficit and purchases from family agriculture. In addition, a multivariable analysis was conducted through multiple linear regression. Results: There was a difference in means in the prevalence of significant stature deficit between the municipalities that bought < 30% and ≥30% of food from family farms for school feeding, with 1.47 points of difference. The linear regression model showed that for each percentage point of increase in the purchase of food from family farms for school feeding by the municipality, there will be on average a decrease of 0.55 points in the prevalence of stature deficit, independent of the other variables. Conclusion: the purchase of food from family agriculture for school feeding in Brazil may contribute to the reduction of the prevalence of stature deficit in children under five years old.

ABSTRACT

ABSTRACT The rate of visual field progression is an essential factor in determining risk of visual disability or blindness in glaucoma patients. Knowledge of the rate of progression of a particular patient, in combination with an estimation of their longevity and other clinical factors, allows clinicians to optimize management by providing appropriately aggressive treatment. Despite decades of research on the treatment of glaucoma, the natural history of glaucomatous visual field progression in untreated and treated patients remains unclear. The purpose of this review is to provide a comprehensive summary of the literature surrounding the rate of visual field progression in glaucoma. Most of the available data pertains to primary open angle glaucoma, but we will also review progression rates in other subtypes of open angle glaucoma, such as pseudoexfoliative glaucoma and normal tension glaucoma, as well as in primary angle closure glaucoma. Specifically, we will cover methods to identify rates of progression, rates of progression in treated versus untreated patients, factors that may influence progression, and lastly, suggest some parameters that might help clinicians in determining acceptable rates of visual field deterioration in patients with glaucoma.


RESUMO A taxa de progressão do campo visual é um fator essencial para determinar o risco de incapacidade visual ou cegueira em pacientes com glaucoma. Conhecer a taxa de progressão de um determinado paciente, em combinação com uma estimativa de sua longevidade e outros fatores clínicos, permite que os médicos otimizem a conduta, fornecendo um tratamento adequadamente agressivo. Apesar de décadas de pesquisa sobre o tratamento do glaucoma, a história natural da progressão do campo visual glaucomatoso em pacientes não tratados e tratados permanece pouco clara. O objetivo desta revisão é fornecer um resumo abrangente da literatura sobre a taxa de progressão do campo visual do glaucoma. A maioria dos dados disponíveis diz respeito ao glaucoma de ângulo aberto primário, mas também revisaremos as taxas de progressão em outros subtipos de glaucoma de ângulo aberto, como o glaucoma pseudoexfoliativo e o glaucoma de tensão normal, bem como o glaucoma primário de ângulo fechado. Especificamente, iremos cobrir métodos para identificar taxas de progressão, taxas de progressão em pacientes tratados versus não tratados, fatores que podem influenciar a progressão e, finalmente, sugerir alguns parâmetros que podem ajudar os médicos a determinar taxas aceitáveis de deterioração do campo visual em pacientes com glaucoma

ABSTRACT

Abstract Objective: To translate Oral Health Literacy - Adult Questionnaire from English to Odia language and test its psychometric properties and assess its influence on oral health status of school teachers. Material and Methods: A cross-sectional survey was performed among 400; 116 (29%) males and 284 (71%) female school teachers of Bhubaneswar. OHL-AQ questionnaire subsequent to being translated to Odia language utilizing World Health Organization recommended translation back translation protocol was then tested for the establishment of its psychometric properties with assistance from the selected expert panel of academicians. The oral health status of participants was assessed using the WHO oral health assessment form-2013. Chi-square, t-tests, one-way ANOVA, and linear regression were used for statistical analysis. Results: Internal consistency of OHL-AQ-O was acceptable with an alpha value of 0.70. Test-retest reliability showed almost perfect agreement (ICC=0.90, CI=0.85-0.93) indicating highly reliable translated scale (p=0.001). Overall mean oral health literacy scores were 13.02±1.86, with about 80% belonging to the high oral health literacy level group. Caries prevalence was 78%, with a mean DMFT of 3.04±2.55. Shallow pockets were absent majorly in teachers belonging to the high oral health literacy group (p=0.01). The multiple linear regression model depicted that only the teaching experience variable added significantly to the prediction (p=0.008). Conclusion: OHL-AQ-O questionnaire was found valid and reliable to measure OHL. Further application of the instrument in other communities and populations will support establishing the external validity of the OHL-AQ-O.

ABSTRACT

Purpose: To analyze the role of serum creatinine levels as a biomarker of intracranial aneurysm outcomes. Methods: This is a prospective analysis of outcomes of patients with intracranial aneurysm. One hundred forty-seven patients with serum creatinine at admission and 6 months follow up were included. Linear and logistic regressions were used to analyze the data. Modified Rankin scale (mRS) was used to assess outcome. Results: Creatinine level was not directly related to aneurysm outcome nor aneurysm rupture (p > 0.05). However, patients with a glomerular filtration rate (GFR) lower than 72.50 mL·min­1 had an odds ratio (OR) of 3.049 (p = 0.006) for worse outcome. Similarly, aneurysm rupture had an OR of 2.957 (p = 0.014) for worse outcomes. Stepwise selection model selected 4 variables for outcomes prediction: serum creatinine, sex, hypertension and treatment. Hypertensive patients had, on average, an increase in 0.588 in mRS (p = 0.022), while treatment with microsurgery had a decrease in 0.555 (p = 0.038). Conclusions: Patients with higher GFR had better outcomes after 6 months. Patients with higher GFR had better outcomes after 6 months. Creatinine presented an indirect role in GFR values and should be included in models for outcome prediction.

ABSTRACT

Introduction Traumatic brain injuries (TBIs) are a public health problem with high economic impact, as well as an important cause of death and sequela in polytrauma patients, affecting mainly young adults. Objective To analyze the temporal trend of TBI incidence in Brazil between 2008 and 2019, according to age group and gender. Methods An ecological study, based on secondary data from hospital admissions for TBI in all Brazilian states between 2008 and 2019. The numbers were collected using the hospital information systemof the Unified Health System in Brazil.We performed a descriptive analysis using the data obtained. Linear regression models were used to measure the incidence trend of TBI in the period adopted. Results The state of Piauí had the highest increase in the incidence of TBI in the country in the last 10 years (coefficient ß»63.43 e p»0.002). The main concern, though, is the increase in the incidence of TBI amongst children (0­4 years old) in the states of Ceará (ß»31.22 and p<0.001 for boys; ß»42.20 and p<0.001 for girls), Paraná (ß»37.26 and p»0.011 for boys; ß»25.90 and p»0.015 for girls), Pernambuco (ß»20.08 and p»0.016 for girls), Mato Grosso (ß»18.76 and p»0.005 for boys; ß»16.11 and p»0.035 for girls), and Distrito Federal (ß»48.87 and p»0.004 for girls; ß»48.28 and p»0.006 for boys). Conclusion The analysis of the results is able to point out improvements that can be made. Besides that, it is remarkably important to redirect public polices to preventive medicine sincemany of the TBI causes are avoidable through awareness and education of the population.

ABSTRACT

Resumo O desafio desta pesquisa é responder quais elementos caracterizam os fatores contingenciais no setor público e como eles influenciam o desempenho socioeconômico municipal. As principais hipóteses testadas neste estudo analisam se os fatores contingenciais ambiente (contexto externo), tecnologia (processos), estrutura (investimentos) e porte (tamanho) têm influência sobre o desempenho socioeconômico dos governos locais. Para tanto, uma pesquisa documental foi realizada junto aos 399 municípios paranaenses, totalizando 1.995 observações relativas ao período de 2013 a 2017, o que corresponde a um ciclo orçamentário completo. Para a análise dos dados, aplicou-se uma regressão linear múltipla com dados em painel. Os resultados revelam que os fatores contingenciais "ambiente" e "porte" afetam positivamente os resultados socioeconômicos, enquanto "tecnologia" apresenta influência negativa e "estrutura" não apresentou resultados significantes. Com base nesses resultados, conclui-se que os fatores externos, aqueles não controláveis pelos gestores, são os que melhor explicam o comportamento do desempenho socioeconômico dos governos locais investigados. Assim, cabe aos gestores implantar políticas públicas capazes de interferir em seu ambiente e incentivar um porte que contribua para o desempenho socioeconômico e atenda aos objetivos da população. De igual modo, os resultados apresentam implicações teóricas, pois contribuem para a literatura no sentido de acrescentar ao fluxo da pesquisa, fundamentada na Teoria da Contingência, elementos que caracterizam contingências no setor público, no âmbito municipal, como observatório social, grau de dependência, planejamento orçamentário, capacidades do órgão público em manter suas despesas correntes, estrutura de pessoal e de investimentos e porte considerando a receita do município.


Resumen El desafío de esta investigación es responder qué elementos caracterizan los factores de contingencia en el sector público y cómo influyen estos elementos en el desempeño socioeconómico municipal. Las principales hipótesis probadas en este estudio analizan si los factores de contingencia entorno (contexto externo), tecnología (procesos), estructura (inversiones) y porte (tamaño) influyen en el desempeño socioeconómico de los gobiernos locales. Para ello, se realizó una investigación documental con los 399 municipios del estado de Paraná, totalizando 1.995 observaciones para el período de 2013 a 2017, lo que corresponde a un ciclo presupuestario completo. Para el análisis de los datos se aplicó una regresión lineal múltiple con datos de panel. Los resultados revelan que los factores de contingencia entorno y porte inciden positivamente en los resultados socioeconómicos, mientras que el factor tecnología influye negativamente y el factor estructura no mostró resultados significativos. A partir de estos resultados se concluye que los factores externos, no controlables por los gestores, son los que mejor explican el comportamiento del desempeño socioeconómico de los gobiernos locales investigados. Así, corresponde a los gestores implementar políticas públicas capaces de interferir en su entorno y propiciar un porte que contribuya al desempeño socioeconómico y cumpla con los objetivos de la población. Asimismo, los resultados también tienen implicaciones teóricas, ya que aportan a la literatura en el sentido de sumar elementos que caracterizan las contingencias en el sector público, a nivel municipal, al flujo de investigación basada en la Teoría de la Contingencia, como el observatorio social, grado de dependencia, planificación presupuestaria, capacidades de la agencia pública para mantener sus gastos corrientes, estructura de personal e inversión y porte considerando los ingresos del municipio.


Abstract This research aims to identify which elements characterize the contingency factors in the public sector and how these elements influence municipal socioeconomic performance. The main hypotheses tested in this study analyze whether the contingency factors environment (external context), technology (processes), structure (investments), and size (population and revenues) influence the socioeconomic performance of local governments. We conducted documentary research with the 399 municipalities of Paraná, totaling 1,995 observations for the period from 2013 to 2017, which corresponds to a complete budget cycle. For data analysis, multiple linear regression with panel data was applied. The results reveal that the contingent factors environment and size positively affect the socioeconomic results, while technology has a negative influence and structure did not present significant results. Based on these results, we conclude that external factors, those not controllable by the managers, best explain the socioeconomic performance of the investigated local governments. Thus, managers need to implement public policies capable of impacting their environment and work towards achieving a population size able to improve socioeconomic performance and meets the population's objectives. As for theoretical implications, this study contributes to the literature by adding elements that characterize contingencies in the public sector, at the municipal level, to the flow of research based on contingency theory, such as social observatory, degree of dependence, budget planning, capacities of the public agency to maintain current expenses, personnel, and investment structure and size, when considering the municipality's revenue.

ABSTRACT

Introducción: El uso de espacios de vida cobra interés investigativo sobre el envejecimiento, por ser una medida de movilidad y participación social, pues refleja factores físicos, psicosociales y ambientales necesarios para el funcionamiento independiente. Objetivo: Identificar los factores asociados con el apoyo social y uso de los espacios de vida en el contexto rural. Métodos: Estudio descriptivo, con 193 adultos mayores de 60 años, del municipio de Samaniego, departamento de Nariño. Se describió el comportamiento del uso del espacio de vida y su relación con variables demográficas, cognitivas, emocionales y psicosociales mediante modelos de regresión lineal y logística. Resultados: La escala LSA presentó una media de 21,68 (DE = 18,6), se observó correlación con la variable edad (Rho = -0,15, p = 0,042) y género (d = -0,05; IC 95 por ciento -0,35 a 0,23). Hubo relación directamente proporcional pero baja con el Test Minimental (Rho = 0,04, p = 0,580) y Yesavage (Rho = -0,13, p = 0,064). Con la escala apoyo social, hubo correlaciones bajas en apoyo emocional (Rho = 0,19, p = 0,009), instrumental (Rho = 0,13, p = 0,062), interacción social positiva (Rho = 0,23, p = 0,001) y apoyo afectivo (Rho = 0,16, p = 0,027). Conclusión: Las características psicosociales y demográficas influyeron en la utilización que el adulto mayor rural hace de su espacio vital(AU)


Introduction: The use of life spaces is gaining research interest regarding aging, as it is a measure of mobility and social participation, insofar it reflects physical, psychosocial and environmental factors necessary for independent functioning. Objective: To identify the factors associated with social support and the use of life spaces in the rural context. Methods: Descriptive study carried out with 193 adults aged over 60 years, from the Samaniego Municipality, Nariño Department. The behavior of the use of life spaces and its relationship with demographic, cognitive, emotional and psychosocial variables were described using linear and logistic regression models. Results: The LSA scale presented a mean of 21.68 (SD=18.6). A correlation was observed with the variable age (Rho=-0.15, P=0.042) and gender (d=-0.05; CI 95 percent: -0.35 to 0.23). There was a directly proportional but low relationship with the Minimental test (Rho=0.04, P=0.580) and Yesavage (Rho=-0.13, P=0.064). With the social support scale, there were low correlations in emotional support (Rho=0.19, P=0.009), instrumental support (Rho=0.13, P=0.062), positive social interaction (Rho=0.23, P=0.001), and affective support (Rho=0.16, P=0.027). Conclusion: The psychosocial and demographic characteristics influenced on how rural older adults make use of their life spaces(AU)
