Abstract Introduction Sensory deficits of the upper airways are common in people with Parkinson disease. Compounded by considerable deterioration of the swallowing function, these deficits may contribute to the elevated rates of morbidity and mortality among this population. Objective To examine the sensitivity of the vocal tracts of people with Parkinson disease using nasal videoendoscopy and to compare the results with paired controls. Methods The present was a prospective, observational, case-control study. Sensitivity assessments were conducted in a sample of 24 people divided into 2 groups: one group of 12 patients with Parkinson’s disease, and a control group with 12 healthy subjects. The study group also underwent a fiberoptic endoscopic evaluation of swallowing and answered the Swallowing Disturbance Questionnaire (SQD) to detect dysphagia. Results There was a significant difference (p < 0.05) in the region of the arytenoid cartilages, showing that sensitivity was better preserved among the control group, and that sensitivity deficits were present in the study group. The qualitative results showed sensorial impairment in the study group than in the control group regarding the base of the tongue, the vestibular folds, and the vocal folds. The study group showed self-awareness regarding the deficits in the swallowing function, but there was no statistically significant association between swallowing function deficits and deterioration of sensorial function among them. Conclusions Sensorial deficits were present in the study group when compared to the healthy subjects, mainly in the qualitative evaluation.

Abstract: This study aimed to screen the public procurement for dental adhesives in a public health system and evaluate the variables associated with the type and cost of purchased materials. A time series was conducted with secondary data collated from the Brazilian Databank of Healthcare Prices (BDHP). All public procurements for adhesive systems registered from 2010 to 2019 were collated. The frequency of purchase was described, and a multiple linear regression model was used to assess the influence of unit price on predictor variables. Multinomial logistic regression was conducted to describe the influence of selected variables on the probability of purchase for different classes of adhesive systems. A total of 2,752 purchases were analyzed, and the total cost of these materials reached US$ 7,022,659.00 in the 10 analyzed years. The 3-step Etch & Rinse adhesives corresponded to 45.63% of the processes, with increased probability of being purchased over time. The process conducted by public universities in recent years, using the auction modality, presented lower unit prices. The year of purchase, the type of institutions, the institution's location, and the procurement modality influenced the procurement process. The performed analyses contribute to the understanding of the variables associated with the procurements for adhesive systems, providing valuable information for rationalizing public expenditure and for implementing evidence-based practices to guarantee cost-effective and clinically effective procedures for users of the Brazilian public healthcare system.

O estudo buscou avaliar as compras de resina composta em um sistema público de saúde e compreender as variáveis associadas com o custo e o processo decisório ao longo dos últimos dez anos. Os dados secundários foram coletados do Banco de Preços em Saúde (BPS), do governo federal, entre 2010 e 2019. Foram selecionadas todas as resinas compostas convencionais e bulk-fill. Os seguintes dados foram coletados: data de compra, tipo e localização da instituição, modalidade de licitação, número de itens comprados, fabricante e preços unitários. Um modelo de regressão linear múltipla avaliou o impacto do preço nas variáveis de licitação, enquanto a regressão logística variada comparou as probabilidades de compra entre os materiais. Foram coletadas 18.138 observações com 2.129.294 unidades compradas e um custo total de USD 43.504.260,00. As resinas convencionais apareceram em 98,5% dos processos de licitação. As resinas convencionais nanofilled foram os materiais mais comprados, com um aumento na probabilidade de compra ao longo do tempo, apesar dos preços mais elevados. Foi previsto um aumento nos preços de materiais bulk-fill em comparação com os convencionais. A probabilidade de compra dessa categoria aumentou em 3,14 vezes por ano. Variáveis sociodemográficas e educacionais influenciam os preços e a probabilidade de compra no sistema de saúde. As resinas nanofilled e bulk-fill são incluídas cada vez mais na prática clínica. Os achados destacam possíveis modificações no padrão de tratamentos de restauração e na maneira que a translação de conhecimento pode ocorrer, desde o desenvolvimento de materiais novos até a aplicação clínica, à luz do impacto econômico dessas modificações.

This study aims to assess the resin composite purchases in a public health system and understand the variables associated with its cost and with the decision-making process over a period of 10 years. Secondary data collection was performed using the Brazilian Healthcare Prices Database (BDHP) from 2010 to 2019. All conventional and bulk-fill composites were selected. Date of purchase, institution type and location, procurement modality, number of purchased items, manufacture, and unit prices were collected. A multiple linear regression model assessed the influence of price in the procurement variables, while a multinomial logistic regression compared purchase probabilities between the materials. In total, 18,138 observations were collected with 2,129,294 purchased units and a total cost of USD 43,504,260.00. Conventional composites appeared in 98.5% of the procurement process. Nanofilled conventional composites were the most purchased materials, with an increased probability of purchase over time, despite its higher prices. An increase in prices was predicted for bulk-fill materials when compared to conventional ones. The odds of purchasing this category increased by 3.14x for every price increase over the years. Sociodemographic and type of institution influences the prices and the probability of procurement in the healthcare system. Nanofilled and bulk-fill resin are increasingly included in clinical practice. These findings highlight possible modifications to the standard-of-care in restorative treatments and how the translation of knowledge may occur from the development of new materials to the clinical application considering the economic impact of these modifications.

El objetivo de este estudio fue evaluar las adquisiciones de resina compuesta en un sistema público de salud y comprender las variables asociadas con el coste y proceso de toma de decisión a lo largo de los últimos diez años. Se realizó una recogida de datos en el Banco de Datos de Precios de Atención Sanitaria (BDHP), de Brasil, de 2010 a 2019. Se seleccionaron todas las resinas convencionales y bulk-fill. Se recogieron: fecha de compra, tipo de institución y localización, modalidad de adquisición, número de ítems comprados, manufactura, y precios unitarios. Un modelo de regresión lineal múltiple evaluó la influencia del precio en las variables de adquisición, mientras una regresión multinomial logística comparó las probabilidades de compra entre los materiales. Se recogieron 18.138 observaciones con 2.129.294 unidades adquiridas y un coste total de USD 43.504.260,00. Las resinas convencionales aparecieron en un 98,5% del proceso de adquisición. Las resinas convencionales de nanorelleno fueron los materiales más comúnmente comprados, con una probabilidad mayor de compra a lo largo del tiempo, pese a sus precios más altos. Se predijo un aumento de los precios en los materiales bulk-fill, cuando se compararon con los convencionales. La probabilidad de compra en esta categoría se incrementa un 3,14x por cada aumento durante el año. Las variables sociodemográficas y educacionales influencian los precios y la probabilidad de adquisición en el sistema de salud público. Las resinas de nanorelleno y bulk-fill están incluidas cada vez más en la práctica clínica. Estos resultados subrayan las posibles modificaciones en el estándar de cuidado de los tratamientos restaurativos, y cómo se produce la transferencia de conocimientos, desde el desarrollo de nuevos materiales hasta su aplicación clínica, a la luz del impacto económico de estas modificaciones.

Aim This study analyzed public procurements for different endodontic materials used in the Brazilian public health system and evaluated the variables related to their cost. Methods A time-series study was performed by screening materials for endodontic application in the public Brazilian Databank of Healthcare Prices from 2010 to 2019. Data were categorized according to material composition and clinical application. The collated variables were used in a multiple linear regression model to predict the impact of unit price in procurement processes. Results A total of 5,973 procurement processes (1,524,693 items) were evaluated. Calcium hydroxides were found in 79% of the observations (4,669 processes). Prices drop each year by US$1.87 while MTAs and epoxy resins are increasingly purchased at higher prices (US$50.87; US$67.69, respectively). The microregion, the procurement modality, and the type of institution had no influence on unit prices in the adjusted model (p > 0.05). Conclusions Calcium hydroxide-based materials were the cheapest and most frequently purchased endodontic materials in the public health care system. Novel formulations are being implemented into clinical practice over time and their cost may be a barrier to the broad application of materials such as MTAs, despite their effectiveness.

RESUMO Objetivo Descrever e caracterizar um achado, o escape posterior tardio de resíduo alimentar na deglutição, segundo idade, gênero e consistência do alimento, que ocorreu no evento. Método A coleta de dados ocorreu por meio da análise de cada exame de videonasoendoscopia funcional da deglutição anteriormente gravado em um ambulatório especializado. A população do estudo contemplou 200 pacientes de ambos os gêneros, na faixa etária entre 46 e 87 anos, com e sem patologia de base para disfagia. As imagens foram estudadas individualmente pelo pesquisador e analisadas por juízes, com o objetivo de identificar e selecionar imagens que constatassem a presença ou ausência do evento em estudo. Resultados Verificou-se o escape tardio em 45 exames do total de 200 analisados. Os exames selecionados para o estudo apresentaram o escape residual posterior tardio em pelo menos uma consistência. A maior frequência do escape posterior tardio ocorreu com o líquido. A análise mostrou significância do evento em estudo com a população que apresentava idades mais avançadas da nossa amostra. Conclusão O escape posterior tardio ocorre predominantemente na consistência líquida, em população mais idosa e sem predomínio de gênero.

ABSTRACT Purpose To describe and characterize a finding, i.e., delayed posterior leakage of food residue during swallowing, according to age, gender and food consistency, which occurred in the event. Methods Data were collected through the analysis of each functional videonasoendoscopy test of swallowing previously recorded in a specialist outpatient clinic. The study population included 200 patients, both males and females, aged between 46 and 87 years, with and without an underlying pathology for dysphagia. The images were studied individually by the researcher and analyzed by judges in order to identify and select images that would confirm the presence or absence of the study event. Results Delayed escape was found in 45 out of the 200 analyzed tests. The tests selected for the study showed delayed posterior bolus leakage in at least one consistency. The highest frequency of delayed posterior leakage occurred with fluids. The analysis showed the significance of the study event with the population related to older ages in the sample analyzed. Conclusion Delayed posterior leakage occurs predominantly in the liquid consistency in older populations with no gender predominance.

Abstract The aim of this study was to evaluate the influence of different calcium phosphates (CaPs) on the physical, biological, and remineralizing properties of experimental resin-based sealants (RBSs). Triethylene-glycol dimethacrylate (90wt%) and bisphenol A-glycidyl methacrylate (10wt%) were used to produce resin-based sealants. Hydroxyapatite (SHAp), α-tricalcium phosphate (Sα-TCP) and octacalcium phosphate (SOCP) were added to the sealants in a 10wt% concentration. One group without CaPs was used as the control group (SCG). The degree of conversion (DC) was assessed with Fourier-transformed infrared spectroscopy, whereas cytotoxicity was tested with the HaCaT keratinocyte cell line. The ultimate tensile strength (UTS) was used to assess the mechanical strength of the experimental RBSs. Sealed enamel was used for colorimetric assay. Mineral deposition was assessed with Raman spectroscopy after 7, 14, and 28 days of sample immersion in artificial saliva. Scanning electron microscopy was used to analyze the surface morphology after 28 days of immersion. The addition of 10wt% of fillers significantly reduced the DC of sealants. SOCP groups showed reduced cell viability. Higher UTS was found for Sα-TCP and SHAp. The color analysis showed that SGC and demineralized teeth presented higher mismatches with the sound tissue. Mineral deposition was observed for SHAp and Sα-TCP after 7 days, with increased phosphate content and mineral deposits for SHAp after 28 days. RBS with the addition of 10% HAp promoted increased mineralization in vitro after 28 days, and did not affect cell viability, DC, mechanical properties, or RBS color in the enamel.

Resumo Introdução Os sintomas depressivos são altamente prevalentes na população idosa (10%). Estes sintomas aparecem frequentemente quando há uma perda de qualidade de vida associada à exclusão social e ao aparecimento de doenças graves. Sentimentos de tristeza, desânimo, desânimo e decepção, e eventos, tais como a perda de amigos próximos e familiares podem também estar relacionados a estes sintomas. As consequências de sintomas depressivos incluem os resultados negativos de saúde oral, tais como uma diminuição na frequência de escovação, maior prevalência de cárie e maior probabilidade do aparecimento de periodontite. Objetivo Este estudo teve como objetivo avaliar a associação entre a presença de sintomas depressivos e comportamento saúde bucal orientada para o problema, bem como a ausência de comportamento de procura de cuidados de saúde. Foram avaliados 872 idosos vivendo em dois distritos de saúde em Porto Alegre. Material e método Eles forneceram informações sobre variáveis socioeconômicas em uma entrevista, e responderam à Escala de Depressão Geriátrica-15 e a um questionário avaliando o comportamento de procura de cuidados dentários. Além disso, foi realizado um exame oral. Quando analisados por meio de regressão de Poisson com variância robusta, as variáveis sexo masculino, menor escolaridade, menor renda, número de dentes reduzidos, presença de restos de raiz e presença de sintomas depressivos foram encontrados para ser associados de forma independente com o resultado. Resultado Houve uma diferença significativa em relação ao comportamento de procura de cuidados dentários em relação aos idosos com sintomas depressivos e aqueles em baixo nível socioeconômico com estatuto oral deficiente. Conclusão Concluiu-se que esses fatores precisam ser levados em consideração ao avaliar o comportamento de procura de cuidados dentários.

Abstract Background Depressive symptoms are highly prevalent among the elderly population (10%). These symptoms frequently appear when there is a loss of quality of life associated with social exclusion and the appearance of severe diseases. Feelings of sadness, discouragement, despondency and deception, and events such as the loss of close friends and family can also be related to these symptoms. The consequences of depressive symptoms include negative oral health outcomes, such as a decrease in the frequency of toothbrushing, greater prevalence of caries and higher probability of the appearance of periodontitis. Aim This study aimed to evaluate the association between the presence of depressive symptoms and problem-oriented oral healthcare behavior, as well as the absence of healthcare-seeking behavior. Material and method 872 elderly people living in two health districts in Porto Alegre were evaluated. They provided information on socioeconomic variables at an interview, and responded to the Geriatric Depression Scale-15 and to a questionnaire assessing dental care-seeking behavior. In addition, an oral examination was performed. When analyzed using Poisson regression with robust variance, the variables of male sex, less schooling, lower income, reduced number of teeth, presence of root remnants and presence of depressive symptoms were found to be independently associated with the outcome. Result There was a significant difference regarding dental care-seeking behavior in relation to elderly people presenting depressive symptoms and those in low socioeconomic strata having poor oral status. Conclusion It was concluded that these factors need to be taken into consideration when evaluating dental care-seeking behavior.

AbstractSkin diseases are common in hospitalized patients. However, there is a lack of data concerning their frequency. The objective of this study is to evaluate the prevalence of dermatological diagnoses in hospitalized patients after consultation requested by nondermatologist physicians to the Department of Dermatology, Hospital de Clinicas de Porto Alegre period of 10 years. A total of 5685 patients were evaluated, representing an average of 48.2 patients per month. The five most frequent groups were infectious dermatoses(33.25%), eczematous dermatoses (11.49%), drug reactions (11.43%), vascular dermatoses (6.81%) and group of pruritus, prurigo nodularis and urticaria (hives) (4.71%).

Este artigo apresenta a análise das transformações das significações sociais da atividade foco deste estudo - a renda de bilro - e suas implicações no processo de constituição de um sujeito aprendiz. As reflexões aqui apresentadas pautam-se nos pressupostos teóricos da Psicologia Histórico-Cultural. O resgate do contexto, isto é, da história do grupo em que este sujeito se insere, bem como da atividade em questão caracterizaram-se como importante aspecto do percurso traçado. Os dados analisados provêm de entrevistas realizadas com o sujeito. O desenvolvimento das análises possibilitou concluir que a constituição do sujeito é um processo complexo, multifacetado e ininterrupto onde a participação dos outros sujeitos tem relevância significativa mas não determinante nas suas escolhas, de maneira a singularizar algo que é socialmente partilhado.

This article presents an analysis of the transformations of the social significations of a handicraft activity, the bobbin-lace, and its implications in the process of constitution of a learner subject. The reflexions here presented rely on the theoretical principles of the sociocultural psychology. The recovering of the context, that means, the history of the group in which the subject takes place, as well as the history of the activity itself were important aspects of the path followed. The analysed data come from enterviews held with the subject. The development of the analysis made it possible to conclude that the constitution of the subject is a complex, multisized and permanent process in which the participation of the others does have a significative relevance but does not play a determinant role over the subject's choices, what allows him/her to turn something socially shared into a singular feature.
