Authors: Giacomini Eduardo , Rizzotto Maria Lucia Frizon
Published: March 2023

ABSTRACT This is a qualitative research, built as an integrative review focused on compiling and analyzing information on the expression of interdisciplinarity in mental health care practices. Data collection took place between May and August 2021, in the BVS, SciELO, Scopus, Academic Google, OpenGrey, and ProQuest databases, in Portuguese, English, Spanish, French, or Italian. Using the SPIDER strategy, the following were defined: scenario, subject of interest, design, evaluation, and type of research, allowing the bibliographic profile of the records to be presented; characterizing the practices and analyze the characteristics of interdisciplinarity in mental health work. The 43 productions that made up the corpus of the study were analyzed descriptively and using thematic content analysis technique, discussed in the light of the theoretical framework of collective health. Four thematic units were identified: ‘concept’, ‘operationality’, ‘objective’, and ‘attributes’. It was concluded that there is a theoretical emptying regarding what characterizes interdisciplinarity in the mental health work scenario; that interdisciplinarity represents an opportunity to overcome the biomedical model of care; and that there are limits and possibilities for its realization. Teamwork, matrix support, and continuing education are considered to favor an interdisciplinary attitude.

RESUMO O ensino da saúde coletiva no Brasil contribui para o desenvolvimento técnico-científico do campo, transcendendo a mera abordagem de programas de saúde de forma fragmentada. Assim, objetivou-se neste estudo compreender a operacionalização do ensino em saúde coletiva, na graduação e pós-graduação stricto sensu, no Brasil. Trata-se de uma revisão integrativa de literatura a partir da busca nas bases de dados PubMed, Scopus, PsycINFO, Literatura Latino-americana e do Caribe em Ciências da Saúde (Lilacs), Scientific Electronic Library Online (SciELO) e Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde (Bireme). Foram analisados 21 artigos por título, autor, ano, caracterização e/ou objetivo, metodologia e principais resultados. Conclui-se que a institucionalização de cursos de pós-graduação no campo da saúde coletiva seguiu o movimento educacional da universidade e a Reforma Sanitária Brasileira, ao passo que cursos de graduação só ocorreram na última década. O marco constitucional de 1988 define o ordenamento de recursos humanos para a formação profissional no e para o sistema de saúde no País.

Published: March 2023

Abstract Considering the side effects in the oral cavity and dental structures of radiotherapy (RDT) for head and neck cancer, this study aimed to evaluate the effects of RDT on the root dentin concerning the obliteration of dentinal tubules, the inorganic composition of intra-radicular dentin, and the integrity of collagen fibers. Thirty human canines were selected from a biobank and randomly divided into two groups (n=15). The samples were sectioned buccolingually, and a hemisection was used for structural analysis by scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometer (EDS). Low-vacuum SEM images were obtained at 2000-x magnification to observe the obliteration of the dentinal tubules. Moreover, compositional evaluation was performed using EDS. After RDT, the SEM and EDS analyses were repeated using the same methodology. RDT was applied fractionally at 2 Gy per day, 5 days per week, for 7 weeks, resulting in a total dose of 70 Gy. The collagen integrity of the irradiated and non-irradiated samples was analyzed using Masson’s trichrome and picrosirius red staining polarization microscopy. Samples subjected to RDT exhibited dentinal tubule obliteration (p < 0.001); low integrity of type I and III collagen fibers (p < 0.05); compositional reduction of calcium (p = 0.012), phosphorus (p = 0.001), and magnesium (p < 0.001); an increased Ca/P ratio (p < 0.001). RDT affects the structure of dentinal tubules, the inorganic composition of intra-radicular dentin, and the collagen fiber integrity in the root dentin, which may interfere with the effectiveness and durability of dental procedures.

Published: March 2023

Abstract This study aimed to investigate the association between serum vitamin D levels and untreated caries and determining factors in children and youth. Methodology: This cross-sectional study used data from the National Health and Nutrition Examination Survey (2013-2014). In total, 3,072 participants with ages ranging from 1 to 19 years were included in our sample. The main dependent variable, untreated caries, was defined as having at least one untreated carious surface in any tooth. Serum concentration of 25-hydroxyvitamin D [25(OH)D] was categorized into four groups: ≥75 nmol/ml, 50-74.9 nmol/ml, 25-49.9 nmol/ml, and <25 nmol/ml. Data were analyzed using a binary logistic regression. Results: For children aged 1-5 years, age (OR = 1.68, 95% confidence intervals (95% CI) 1.38-2.04) and low levels of vitamin D (25-49.9 nmol/ml, and <25 nmol/ml: OR = 2.55, 95% CI 1.06-6.13) were associated with untreated caries. For children aged 6-11 years, low levels of vitamin D (50-74.9 nmol/ml: OR=1.45, 95% CI 1.16-1.82) remained associated with untreated caries. No associations were found in those between 12 and 19 years of age. Conclusion: Our findings show an association between low levels of 25(OH)D and untreated caries in children between 1 and 11 years of age, suggesting that this nutrient might interfere in the caries process.

Published: March 2023

Abstract Foam has been used worldwide as a vehicle for the professional application of fluoride and hypothetically should have the same anticaries potential as conventional fluoride gel (F-gel) in terms of the formation of reaction products with enamel. Thus, the ability of Flúor Care® foam (FGM, Joinville, SC, Brazil, 12,300 ppm F, acidulated) to react with enamel was evaluated in comparison with Flúor gel® (DFL, Rio de Janeiro, RJ, Brazil, 12,300 ppm F, acidulated). Slabs (n=10/group) of sound enamel and with caries lesion were used, in which the concentrations of total fluoride (TF), and loosely (CaF2-like) and firmly (FAp) bound types were determined. The importance of agitation during application was previously tested. The determinations were made with fluoride ion-specific electrode and the results were expressed in μg F/cm² of the treated enamel area. ANOVA and Tukey tests were used to analyze the difference among treatments, independently for sound and carious enamel. The agitation of the products during application significantly increased the reactivity of the foam (p<0.05), but not that of the gel (p>0.05). The foam did not differ from F-gel (p>0.05) concerning the formation of TF and CaF2-like in sound or carious enamel. Regarding FAp, the foam did not differ from F-gel (p>0.05) in the carious enamel, but the concentration in the sound was lower (p<0.05). The results show that this commercial fluoride foam tested needs to be agitated during application to improve its reactivity with enamel, which raises a question about other brands.

Resumo Este ensaio reflete as condicionantes do poder em uma sociedade marcada pela emergência do conservadorismo que põe em risco a dignidade e os direitos humanos conquistados no período pós-ditadura militar brasileira. A partir do pensamento de autores críticos, tecemos considerações sobre como enfrentar essa nova configuração social e garantir a proteção dos direitos humanos. Para tanto, pensar o papel da universidade numa perspectiva praxiológica de ação política comprometida com a mudança social pressupõem buscar alternativas, saídas psicopolíticas, para uma sociedade capitalista submergida numa crise civilizatória. Como parte dessa análise, abordamos casos como o do assassinato de Marielle Franco, decorrente do avanço do conservadorismo e da violência política que o acompanha.
Thermorheological characteristics and extrudability aptitude of a new amylose-free cassava starch
Authors: Diaz Adriana Pulido , Valle Guy Della , Longas Freddy Forero
Published: March 2023

ABSTRACT Cassava crops have always been fundamental in human nutrition and industry. Nowadays, the development of new cultivars with specific properties has become a major research area. In this research, amylose-free cassava starch (WXCS) extracted from clone AM206-5 was evaluated with respect to its physicochemical, morphological, and thermorheological properties. The waxy nature of cassava starch was verified (0.54 ± 0.09% w/w amylose), showing a 16.92±0.20 µm average granule size and elliptical or spherical truncated shapes without granule aggregation. There were significant differences in the pasting profiles evaluated, with WXCS being thermally less stable (Breakdown = 698±2 cP) generating less viscous final pastes (731±16 cP) compared to a commercial amylose-free corn starch. The WXCS shear viscosity was determined in a capillary rheometer (Rheoplast®), showing an inverse linear temperature dependence, decreasing by a factor larger than 3 when the temperature changed from 100 to 120 °C, with a pseudoplastic flow described by the power law (n: 0.25-0.40), consistency index (32607 - 6695 Pa.s) and specific mechanical energy (124 - 75 J/g). The extensional viscosity was always higher than the shear viscosity, where increasing the strain rate and temperature enlarged the Trouton number (25-145). Complete WXCS transformation under real process conditions was achieved with a 30% w/w moisture content and 100 °C, which induced full granular integrity loss and crystalline structure destruction. The results confirmed a potential utilization for this new starch to obtain extruded-type food products or to serve as a biothickening agent.
Communication capacity of NHC entities in digital media: are there significant asymmetries among segments?
Authors: Dias Bruno Cesar , Ouverney Assis Mafort
Published: March 2023

Abstract This work presents the results of a study that analyzed the processes and communication strategies by the entities represented in the National Health Council (NHC), 2018-2021 administration. The production of alternative communication by civil society constitutes one of the fundamental principles of democratic regimes for an important American institutionalist author (Robert Dahl). The emergence of the Internet and social networks has brought new demands for these organizations to disseminate their ideas and be present in this network society (Castells). Our study aimed to analyze the extent to which these entities are present in the digital media and to verify if there were significant differences in the communication capacity among the segments represented in the NHC. A survey was applied to the communication departments of the 42 NHC entities from September 2019 to February 2020. Thirty-four answers were obtained (81%). The results show the existence of 3 different levels of development in communication within these entities, regardless of the macro-institutional categories. Our article ends by discussing the results in light of the polyarchy and the digital democracy models and highlighting new steps towards effective democratic communication policies and participation.

Published: March 2023

Abstract This study aimed to gather evidence on the adequacy of the General Health Questionnaire (GHQ-12) in Brazil, considering a random sample of Brazilian physicians. Specifically aimed: (1) to test the GHQ-12 bifactor structure compared to alternative models, (2) to check its factorial invariance regarding to gender and the diagnosis of mental and behavioral disorders, and (3) to know the association of this measure with indicators of poor health (e.g., suicidal thoughts, decreased libido, medication use). The study included 1,085 physicians with a mean age of 45.7 (SD = 10.6), mostly male (61.5%), married (72.6%) and Catholic (59.2%). They answered the GHQ-12, the Positive and Negative Suicidal Ideation Inventory, and demographic questions. The best fit model was the bifactor structure composed of anxiety and depression, in addition to a general dimension, which presented Cronbach’s alpha, McDonald’s ω and composite reliability higher than 0.70 just for a general fact. Psychological distress scores correlated with suicidal ideation and indicators of health and sexual satisfaction. This is a psychometrically suitable instrument that can be used in terms of its total, but its specific factors need to be used with caution.

Resumo O objetivo deste estudo foi estimar a cobertura populacional e a taxa de incremento anual (TIA) média, em âmbito nacional, do registro de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan), entre 2015 e 2019, considerando a entrada dos dados via Estratégia e-SUS APS e Sisvan Web. Trata-se de estudo ecológico de séries temporais, com estratificação por macrorregiões e faixas etárias. A TIA da cobertura foi calculada utilizando regressão de Prais-Winsten e a correlação com IDH, PIB per capita e cobertura da APS foi avaliada por teste de Spearman. A cobertura populacional do registro de marcadores de consumo alimentar no país foi de 0,92% em 2019, com TIA significante de 45,63% desde 2015. As maiores coberturas foram observadas na região Nordeste (4,08%; TIA=45,76%, p<0,01) e em crianças entre 2 e 4 anos (3,03%; TIA=34,62%, p<0,01). Houve tendência crescente para a entrada dos dados via e-SUS APS, em detrimento do Sisvan Web. A TIA da cobertura dos registros via e-SUS APS exibiu correlação positiva com IDH e PIB per capita em alguns recortes etários. A cobertura populacional do registro de marcadores de consumo alimentar do Sisvan ainda se mostra incipiente no país e o e-SUS APS parece ser uma estratégia relevante para sua expansão.

Published: March 2023

Abstract The aim of the present study was to estimate the population coverage of recording food intake markers in Brazil’s Food and Nutrition Surveillance System (Sisvan) and mean annual percent change (APC) in coverage according to the system used for data entry (e-SUS APS and Sisvan Web). We conducted an ecological time series study of the period 2015-2019. The data were stratified into region and age group. APC in coverage was calculated using Prais-Winsten regression and the correlation between APC and HDI, GDP per capita and primary healthcare coverage was assessed using Spearman’s correlation coefficient. Population coverage of recording food intake markers at national level was 0.92% in 2019. Mean APC in coverage throughout the period was 45.63%. The region and age group with the highest coverage rate were the Northeast (4.08%; APC=45.76%, p<0.01) and children aged 2-4 years (3.03%; APC=34.62%, p<0.01), respectively. There was an upward trend in data entry using e-SUS APS, to the detriment of Sisvan Web. There was a positive correlation between APC in coverage using e-SUS APS and HDI and GDP per capita in some age groups. Population coverage of recording Sisvan food intake markers remains low across the country. The e-SUS APS has the potential to be an important strategy for expanding food and nutrition surveillance.
Single waiting list for hospital beds during the COVID-19 pandemic: performance of the Federal Legislative Branch in 2020

Published: March 2023

Abstract This study investigated legislative proposals on the single waiting list for hospitalizations and ICU beds within the scope of the Federal Legislative Branch in the first year of the pandemic (2020). This was an exploratory, qualitative, and document- based study, which analyzed bills analyzed in the Brazilian National Congress on the subject. The results were organized according to the authors’ profile and qualitative content of the bills. There was a predominance of male parliamentarians, affiliated with left-wing parties and professional training in areas other than health. Most bills dealt with a general single waiting list, specifying hospital beds, the mixed management of hospital beds, and indemnity through the Brazilian Unified Health System’s (SUS, in Portuguese) price table. The House of Representatives presented more bills, but no progress was made in their processing. Among the analyzed bills, only one was prioritized in the External Commission to Combat COVID-19. It was concluded that the Federal Legislative Branch once again missed the chance to legislate for the future and prepare the country with a normative framework capable of confronting health emergencies, which will demand much from health managers and SUS itself.

Abstract This article aims to investigate the association between remote work and Back Pain during the COVID-19 pandemic, and to analyze this relationship according to the body mass index. Population-based, cross-sectional study carried in two cities in southern Brazil, in individuals aged 18 years and over. Data were collected through household interviews from October to January 2020/21. Outcomes: back pain (cervical, thoracic, lumbar/acute, chronic) and pain intensity. Exposure variable: remote work. For the analyses, Poisson regression with robust adjustment for variance was used, stratified by BMI (eutrophic vs overweight/obese), and restricted to those who had worked in the past month. 1,016 had worked during the pandemic, average 42 years old (SD = 14), varying from 18 to 93 years. Remote work was performed by 7.7% of the individuals. Prevalence of back pain: 25.6% (95%CI: 19.5 to 31.7%). Overweight/obese remote workers felt pain acute cervical pain PR = 2.82 (95%CI: 1.15 to 6.92); chronic low back PR = 1.85 (95%CI: 1.04 to 3.29); acute thoracic PR = 1.81(95%CI: 3.76 to 8.68) compared to those who did not work. About one in four remote workers reported back pain during of the COVID-19 pandemic. BMI proved to be an important moderator between outcomes and exposure variable.

Published: March 2023

RESUMO A concentração de minérios fosfáticos ricos em carbonatos através de flotação convencional é dificultada devido às similaridades de suas propriedades superficiais. Assim, surge a flotação reativa baseada na retenção de dióxido de carbono produzido pelos carbonatos em meio ácido. Diante das atuais demandas de novas técnicas de concentração, este trabalho investigou a flotação reativa do minério fosfático sílico-carbonatado. Para tanto, amostras das faixas granulométricas, –10# +20# (–1,70 mm +0,84 mm) e –20# +65# (–0,84 mm +0,210 mm) foram empregadas durante o processo. Os ácidos, sulfúrico e fosfórico, bem como o polímero álcool polivinílico (PVA) foram avaliados por intermédio de ensaios de planejamento fatorial. O ácido fosfórico favoreceu a redução da relação CaO/P2O5, bem como a elevação do teor de P2O5, sendo o melhor resultado, aquele que proporcionou aumento de cerca de 30% no teor de P2O5 (12,3 para 16%) na faixa –20# +65#, ao utilizar 10% (v/v) de ácido fosfórico e 0,5% (m/v) de PVA. Embora tenha-se conseguido atingir, em alguns testes, o parâmetro industrial para a relação CaO/P2O5 (inferior a 1,6), o mesmo não ocorreu para os teores de MgO (inferior a 1%). Os resultados são promissores, entretanto, novos estudos com alternativas mais sustentáveis são extremamente necessários atualmente.

Resumen Objetivo: la atención centrada en la familia durante procedimientos invasivos ha sido respaldada por muchas organizaciones profesionales dedicadas al cuidado de la salud. El objetivo de este estudio fue evaluar las actitudes de los profesionales de la salud con respecto a la presencia de los padres durante los procedimientos invasivos realizados en niños. Método: a los prestadores de atención médica en Pediatría (divididos en categorías profesionales y rangos de edad) de uno de los hospitales más importantes de España se les solicitó que respondieran un cuestionario y redactaran comentarios de texto libre. Resultados: un total de 227 profesionales respondieron la encuesta. En sus respuestas, la mayoría (72%) de los participantes informó que, en ocasiones, los padres están presentes durante las intervenciones, aunque se registraron diferencias entre las distintas categorías profesionales al respecto. Los procedimientos en los que los padres estuvieron presentes se consideraron como “menos invasivos” (96% de los casos), mientras que solamente el 4% estuvo presente en los considerados “más invasivos”. A mayor edad de los profesionales, menos necesaria se consideró la presencia de los padres. Conclusión: las actitudes con respecto a la presencia de los padres durante procedimientos pediátricos invasivos se vieron influenciadas por la categoría profesional, la edad del prestador de salud y la invasividad de los procedimientos.

Abstract The Brazilian Caatinga has already lost extensive areas of original vegetation, thus it becomes imperative to perform fauna inventories within this region to fill geographical sampling gaps. Herein, we present a taxonomic list of the herpetofauna of a mountain chain located in the central zone of Rio Grande do Norte (RN) state whose region includes two priority areas for conservation of the Caatinga: “CA087 – Serra de Santana” in the west, and “CA078 – Nascente do Potengi” in the east. The sampling was carried out using methods of visual searching, pitfall traps with drift fences, specimens rescued during vegetation suppression activities in wind energy projects, occasional encounters, and third-party records. We recorded 19 amphibian species and 53 reptile species (23 lizards, 24 snakes, five amphisbaenians and one chelonian). About half of the recorded species have distributions entirely or mostly in the Caatinga. The mountain range sampled in this study harbors virtually all species found in nearby lowlands of the “sertaneja” depression of RN state, plus some relevant species with relictual distributions in the Caatinga, highlighting the importance of these highland areas for conservation of the Caatinga herpetofauna.

ABSTRACT The objective of this study was to evaluate the physiological indices of sour passion fruit under brackish water irrigation strategies and potassium fertilization. The study was carried out under field conditions in São Domingos, PB, Brazil, using a randomized block design in a 6 × 2 factorial scheme, with treatments consisting of six brackish water irrigation strategies (irrigation with moderately saline (1.3 dS m-1) water throughout the crop cycle - WS; irrigation with high-salinity (4.0 dS m-1) water in the vegetative stage - VE; flowering stage - FL; fruiting stage - FR; successively in the vegetative/flowering stages - VE/FL; and vegetative/fruiting stages - VE/FR) and two doses of potassium (207 and 345 g K2O per plant per year, corresponding, respectively, to 60 and 100% of recommendation), with four replicates and three plants per plot. Irrigation with water of 4.0 dS m-1 reduced the osmotic and water potentials in the leaf blade, synthesis of chlorophylls a and b, transpiration, and instantaneous carboxylation efficiency of sour passion fruit, regardless of the development stage. Salt stress in the vegetative, flowering, fruiting, and successively in the vegetative/flowering and vegetative/fruiting stages increases intercellular electrolyte leakage in sour passion fruit. Fertilization with 100% of the K recommendation increased stomatal conductance, CO2 assimilation rate, and instantaneous water use efficiency of sour passion fruit cv. BRS GA1 under irrigation with water of 1.3 dS m-1 throughout the crop cycle.

ABSTRACT The objective of this study was to evaluate the effect of irrigation with low- and high-salinity water on the increment of salts in the soil, the production components of sour passion fruit and the leaching of salts by rainfall and by leaching fraction of 10%. The treatments were arranged in randomized blocks, in a split-plot scheme, corresponding to three irrigation management practices [evaluation of soil chemical attributes before irrigation; and after irrigation with water of low electrical conductivity (0.35 dS m-1), and high electrical conductivity (4.00 dS m-1) in the main plot], and in the subplot two soil depths of evaluation (0-20 and 20-40 cm) and three soil sampling times (at 115 days after transplanting of seedlings (DAT) - beginning of flowering; at 199 DAT - end of the dry season; and at 379 DAT - end of the rainy season). Irrigation increased the electrical conductivity of the soil saturation extract, with higher values in the surface layer and at the end of the dry season. Rainfall during the rainy season reduced the saline character of soil from moderately saline and strongly saline, in treatments irrigated with water of low and high electrical conductivity, to non-saline and slightly saline, respectively. Irrigation with high-electrical conductivity water negatively affected the production components and yield of sour passion fruit.

ABSTRACT Using nematode-resistant and/or -tolerant rootstock is a strategy that has maintained guava cultivation feasible in the irrigated perimeters of the Brazilian semi-arid region. The objective was to evaluate the production, gas exchange, and fruit quality of ‘Paluma’ guava with and without nematode-tolerant rootstock under different irrigation depths and production periods. The experimental design was randomized blocks, in the mixed 2 × 4 × 2 factorial scheme, corresponding to two forms of cultivation of ‘Paluma’ guava (without and with nematode-tolerant rootstock), four irrigation depths (60, 80, 100, and 120% of crop evapotranspiration - ETc), and two production periods, with four replicates. Guava plants were evaluated for physiological, production and post-harvest quality parameters. Gas exchange in ‘Paluma’ guava leaves was higher in the second production cycle, under irrigation depths above 100% ETc, not differing with the use of the rootstock. The use of the rootstock ‘BRS Guaraçá’ promotes a greater number of fruits and production with the increase of the irrigation depth, mainly in the second half of the year, with the increase of soluble solids and titratable acidity in the fruits.

ABSTRACT Tahiti lime is a species of great economic importance worldwide. In Brazil, production is concentrated in the states of São Paulo and Pará, where it is usually grafted onto the Rangpur lime. This study aimed to analyze the effects of different irrigation depths on the fruit yield, phenology, and gas exchange of Tahiti lime trees grafted onto Swingle citrumelo. Irrigation was performed during the first year at four different irrigation depths in a random block design with five blocks and four treatments to maintain the soil matric potential in the following ranges: T1: below -50 kPa, T2: from -30 to -50 kPa, T3: from -10 to -30 kPa, and T4: above -10 kPa. The flowering, carbon assimilation rate (A), stomatal conductance (gs), transpiration (E), and fruit yield were measured. Fruits were harvested earlier in the most irrigated treatment, T4, and the yield increased from 2.22 to 6.89 kg per plant from T1 to T4. The average fruit weight escalated from 78.6 to 96.1 g from T1 to T4, and carbon assimilation increased from 6.89 to 9.51 μmol CO2m-2s-1 from T1 to T4.
A blockchain-based model for token renewable energy certificate offers

ABSTRACT This article proposes an investment model for a renewable energy generator that allows it to earn the right to issue Renewable Energy Certificates (RECs) and sell them through quarterly sales auctions promoted by the blockchain. Blockchain technology can further promote the RECs market, as it enables tokenization and distribution of certificates. We did not find articles in the literature that analyze the decision to invest in decentralized autonomous organizations (DAOs) that have rules for issuing and trading RECs specified in smart contracts, which are executed and validated by the blockchain. This article contributes to the literature on blockchain technology applications in the renewable energy market by proposing issuing and selling RECs tokens through a DAO. The relevance of this research is that it shows that simple real option pricing methods can help decision-makers evaluate investment opportunities under uncertainty and flexibility. The tokenization and distribution of RECs via blockchain can promote transaction agility, reduce or eliminate bureaucracy in the means of payment, and increase the security and transparency of transactions. We propose a model for issuing and selling RECs in smart contracts. We assume that the generator has the flexibility to invest now or in one year to enter the platform, considering the energy generated in one year by a single typical 4MW wind turbine. Our model assumes that the price of the REC token follows an inverse demand function subject to stochastic shocks. The results contribute to the understanding of the performance dynamics of digital products under uncertainty and flexibility and show that distributed ledger technology (DLT) may be a viable alternative for renewable energy incentives.
Variação do dividend-yield como critério de seleção de ativos em estratégias de momento de fundos de investimentos imobiliários brasileiros

Published: March 2023

RESUMO Nosso objetivo foi mostrar o uso da variação do rendimento de dividendos (dividend-yield [DY]) como critério de seleção dos fundos de investimentos imobiliários brasileiros (FII-BR) em estratégias de momento. A identificação de momento em FII-BR com base nesse critério de seleção é, até onde sabemos, nova e origina diferentes estratégias que capturam retornos anormais. Este estudo proporciona uma nova compreensão da dinâmica entre preços e pagamentos de dividendos, que compõem os retornos dos FII-BR. Isso assume grande importância, considerando a relevância do DY para a classe de ativos. As estratégias estudadas apresentaram resultados acima dos índices do setor com expressiva magnitude, sua elaboração é simples e elas podem ser aplicadas por qualquer investidor individual ou institucional. Os desempenhos das carteiras foram mensurados por meio do índice de Sharpe (IS), do alfa do modelo de três fatores de Fama e French e dos retornos excessivos obtidos em relação ao índice FII-BR. Testes estatísticos foram aplicados para verificar a significância dos resultados. Este estudo mostrou que estratégias em torno do efeito de momento que compram (vendem) FII-BR com maiores (menores) variações de DY em meses anteriores tendem a apresentar desempenho superior ao índice do setor.

Abstract Introduction: The expansion of higher education in Brazil is recent. In the medical field, with the advent of the “Mais Médicos” Program, this expansion became feasible and culminated with the publication of new National Curricular Guidelines (DCN, Diretrizes Curriculares Nacionais) for undergraduate medical courses. The Pedagogical Course Project (PCP) translates what is accomplished in the course and works as an instrument of communication between the institution and society. The analysis of the PCPs of Higher Education Institutions provides the identification of elements that point to the convergence or move away from the changes proposed by the DCN 2014. Objective: To describe demographically in Brazil the number of public and private medical courses by state and region of the federation, the number of available vacancies, and access to the PCPs of these schools through a systematized methodology. Method: A study was carried out in all institutions with medical courses in Brazil by the year 2021. The search for the PCPs was carried out in the institutional website. In case of lack of information, an electronic message was sent to the medical course coordination. When it was not possible to contact the coordinator directly through the institutional website, a message was sent to the coordinator by accessing their curriculum lattes. Results: A total of 336 medical schools were identified, 115 (34.2%) of which were public and 226 (65.8%) private ones. A higher concentration of courses was observed in the southeast region (41.3%), followed by the northeast region (24.6%). Of the public institutions, the northeast region has the highest concentration of schools (35.6%), followed by the southeast region (26%). The opposite was observed regarding the private institutions. A total of 134 PCPs were obtained (39.8% of the total), 83% from public schools and 17% from private ones. Conclusion: Although the availability of the pedagogical information document on the institution’s website is an obligation, this was not verified in reality, which makes it necessary to implement policies for valuing and monitoring PCP availability, thus facilitating its access by the most interested parties: students, the academic community and researchers in the field of medical education.

ABSTRACT Salivary gland tumors account for only 3%–5% of all tumors in the head and neck, 10%–15% of which originate from minor salivary glands. Pleomorphic adenoma is a benign lesion of the salivary gland, most commonly occurring in the region of the hard and soft palates. The treatment of choice for pleomorphic adenomas is with the partial or total function of the extension of the lesion, and placing palatal obturators are one method of reestablishing masticatory function and facial esthetics. This study aimed to rehabilitate a patient using a palatal implant following partial maxillectomy for the removal of a pleomorphic adenoma. A young patient with pleomorphic adenoma of the hard palate underwent a partial right-sided maxillectomy procedure which removed the hard palate and alveolar regions of the molars. Prior to surgery, the patient was assessed to make a surgical guide for resection of the tumor, as well as a provisional obturator plate using orthodontic wire clasps. After healing, the patient was rehabilitated using a palatal obturator which had been incorporated into a removable partial denture. The clinical sequence used to fabricate the final prosthesis was as follows: initial molding after surgery, prosthesis design, preparation of the mouth, work molding, structure testing and orientation planning, teeth testing and installation, and periodic maintenance. Thus, we can conclude that the palatal obturator is an excellent means of restoring a patient’s oral function, facial esthetics, and overall quality of life.

Abstract Objective: The aim of this study was to analyze which equation best estimates maximal heart rate (HRmax) for the pediatric population according to body mass. Data source: We performed a meta-analysis (PROSPERO No. CRD42020190196) of cross-sectional studies that aimed to validate or develop HRmax equations and that had children and adolescents as samples. The search was conducted in Scopus, Science Direct, Web of Science, PubMed, and Biblioteca Virtual em Saúde with the descriptors “prediction or equation,” “maximal heart rate,” “maximum heart rate,” “determination of heart rate,” children, and adolescent. The TRIPOD Statement tool was used to assess the methodological quality and the relevant data were extracted for analysis. The meta-analysis was conducted in the Comprehensive Meta-Analysis, adopting p<0.05 and a 95% confidence interval (CI). Data synthesis: In total, 11 studies were selected, of which 3 developed predictive equations, 10 performed external validity of the preexisting models, and 1 incremented values related to equations already developed. The results of the methodological quality analysis showed a moderate rating in most studies. The 164 + (0.270 × HRres) – (0.155 × body mass) + (1.1 × METs) + (0.258 × body fat percent) (r=0.500, 95%CI 0.426–0.567, p<0.001) and 166.7+ (0.46 × HRres) + (1.16 × maturation) (r=0.540, 95%CI 0.313–0.708, p<0.001) equations presented stronger correlations with measured HRmax in nonobese adolescents. The predictive model developed by 208 – (0.7 × age) showed a greater accuracy among the possible models for analysis (SDM=-0.183, 95%CI -0.787 to -0.422, p=0.554). No specific predictive equation was found for obese adolescents. Conclusions: Future research should explore new possibilities for developing predictive equations for this population as a tool to control exercise intensity in the therapeutic management of childhood and adolescent obesity.
