title: Characterization of whitening toothpastes and their effect on the physical properties of bulk-fill composites

description: Abstract Objective To characterize activated charcoal and 2% hydrogen peroxide-based toothpastes and investigate their effects on roughness, color change, and gloss of bulk-fill composite resin. Methodology Composite resin specimens (Aura Bulk Fill, SDI) were subjected to 5,000 brushing cycles with regular toothpaste (Colgate Total 12, [RT]), activated charcoal toothpaste (Bianco Dental Carbon, [AC]), or hydrogen peroxide-containing toothpaste (Colgate Luminous White Advanced, [HP]), with or without coffee exposure. The pH, particle characterization by scanning electron microscopy (SEM), and weight% of solid particles in the toothpaste were assessed. Roughness (Ra) was evaluated using a surface profile-measuring device, color change (∆Eab/∆E00) by reflectance spectrophotometer, and gloss unit (GU) by glossmeter. Kruskal–Wallis, Dunn, Friedman, and Nemenyi tests were used, and the correlation coefficient test was performed between Ra and GU (α=0.05). Results RT presented a higher Ra after brushing and did not change after staining with coffee; moreover, the ∆Eab/∆E00 values were higher for RT than HP. Regarding gloss, AC and HP obtained higher values compared to RT. A significant negative correlation between gloss and Ra was found for RT exposed to coffee. All toothpastes had a neutral pH; however, RT had the largest percentage of solids by weight. SEM images showed particles of many sizes: irregular shape (RT), more regular particles (AC), and spherical clusters (HP). Although surface roughness, color change, and gloss may compromise the longevity of restorations, the whitening toothpastes tested did not promote more morphology changes than regular toothpastes.

title: There is no shortage, but inequality: demographic evolution of neurologists in Brazil (2010–2020)

description: Abstract Background Neurology is a medical specialty that deals with prevalent diseases such as stroke, headache, epilepsy, and neurodegenerative diseases. Many countries, such as Brazil, struggle to provide neurological care for their populations, but the inadequacy and unequal distribution of the neurologist workforce are real challenges. Objective To analyze the demographic evolution of neurologists and the first-year Neurology residency positions in Brazil during the last decade (2010–2020) and the distribution imbalance between regions. Methods The demographic and geographic distribution of neurologists was calculated based on data extracted from the Brazilian Federal Medical Council reports, and the number of Neurology residency positions was based on the Brazilian National Commission of Medical Residency reports. Indicators of wealth were associated with demographic data. Results The number of neurologists per 100,000 population has increased since 2011, with a similar increase in the geographic distribution of neurologists. However, there was a marked inequality of distribution of neurologists through regions, with a gap between the Northern (lowest) and Southeastern (highest) regions. Furthermore, the imbalance of distribution of neurologists strongly correlated with social inequality. The number of Neurology residency positions increased, but with an imbalance between North and Southeast regions. Conclusions Brazil has advanced in providing neurologists. However, instead of a shortage, inequality between regions is the greatest challenge regarding the neurological workforce. The training of new neurologists is unequal between regions and occurs at a slower rate than needed. Neurologists, public health authorities, and patients should discuss solutions for these issues.

title: Neuromuscular Electrical Stimulation in Facial Aging: an Integrative Literature Review

description: ABSTRACT Despite of being a natural physiological process, aging is considered a degenerative process with evident effects on aging skin, such as reduced elasticity, wrinkles, reduced facial fat and muscle tone, sagging, changes in facial contour, and sarcopenia on the face. These changes can generate social stigma, suffering, and psychological discomfort for the patient. Thus, this study aimed to evaluate the effectiveness of Neuromuscular Electrical Stimulation (NMES), a technique used in physical therapy for muscle training, in attenuating the signs of facial aging. For this purpose, a scientific survey of publications indexed on the Medline (PubMed), CINAHL, Embase, PEDro, Lilacs, ERIC, Scopus, Web of Science, and Google Scholar databases was conducted and, based on pre-established criteria, two relevant publications for the topic were selected for discussion. The scientific literature regarding the use of NMES to attenuate the signs of aging is still very scarce. The survey showed the need to discuss the current state of knowledge. Our results suggest that, theoretically, NMES could be a promising method to attenuate the signs of aging; however, there are still no conclusive results regarding the clinical effectiveness of using NMES in the facial muscles since few studies relate NMES to facial rejuvenation. More studies are needed, with greater methodological rigor and low level of bias, using precise techniques in the evaluation and allowing to interpret with greater scientific commitment of the physiological mechanism of the muscular stimulus and its interrelation with the integumentary system, proving its effectiveness in the improvement of skin appearance.

title: Monument-building of Brazilian Independence (1823-1923): from planning to use, operation, and maintenance

description: ABSTRACT The monument-building is the result of sixty early years of efforts to build a commemorative landmark to the proclamation of Independence of Brazil, whose most effective developments led to the installation of the Paulista Museum. The goal of this article is to highlight the stakeholders and consenting parties’ efforts to plan, program, design, build, adapt, use, operate, and maintain the monument-building between 1823 and 1923. To this end, documentary research was developed from a historical series of the Revista do Museu Paulista and the Anais do Museu Paulista. As a result, evidence was obtained on important decision-making, such as (1) the option of an architectural monument instead of a sculptural one in the planning phase; (2) the application of the golden ratio in the design phase; (3) costs and deadlines in the construction phase; and (4) efforts to conserve, adapt, and improve the monument-building and surroundings in the phases of use, operation, and maintenance. This article is part of the studies related to the doctoral research of one of the authors, which seeks to better understand the facility management, related to operation and maintenance activities, with the potential to be implemented in the Novo Museu do Ipiranga.

title: Sociodemographic Profile of Acute Myocardial Infarction in Rio De Janeiro, Brazil (2010-2019)

description: Abstract Background Cardiovascular Diseases (CVDs) are the main cause of mortality in Brazil, which includes acute myocardial infarction (AMI). In 2017, 12% of deaths caused by infarction in Brazil occurred in the state of Rio de Janeiro, characterizing it as an important “hotspot” in the country. Objectives This study aimed to characterize the population affected by AMI over the past decade within the state so as to guide future public policies related to CVDs. Methods Secondary data of patients affected by AMI between 2010 and 2019 were obtained by DATASUS. In-hospital case-fatality rates, mortality rates, and proportional mortality were calculated using information gathered by the Mortality Information System (SIM) and demographic statistics produced by the Brazilian Institute of Geography and Statistics (IBGE). Results The main results showed that in-hospital case-fatality rates were higher in women, patients aged 60 years and over, the black color/race, and the state's Northwest region. The mortality rate was higher among men, especially in the South-central region and those over 50 years of age. People aged 40-49 years presented a considerable risk of death by infarction. The major categories of data classified as “ignored” in hospital admissions and death certificates were those related to race and education level. Conclusions Prevention should not only focus on the elderly, but also on people over 40, especially men. The incompleteness of electronic public data systems can affect the use of race/color or education level as epidemiological variables. New studies should be conducted to understand why the South-central region is so heavily affected by infarction.

title: Prevalence of Atrial Fibrillation in Patients With end Stage Renal Disease

description: Abstract Background Atrial fibrillation (AF) is the most common arrhythmia in patients with end-stage renal disease (ESRD). The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA2DS2VASC) and bleeding (HASBLED) risk scores. Methods Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15.417; p&lt;0.001), age of 65 years or older (χ2=14.584; p&lt;0.001), and anticoagulation (χ2=5.715; p&lt;0.01) were associated with AF. The median CHA2DS2VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials.

title: Applicability of an HPLC method for analysis of alcoholic and glycolic Brazilian green-propolis extracts

description: Abstract Brazilian green propolis has been widely used in food and pharmaceutical products due to its valuable source of phenolic compounds and versatile biological activities. The development and validation of analytical methods are extremely useful for the characterization and quality control of products containing propolis. Therefore, the aim of this study was to optimize, validate and investigate the applicability of a reversed-phase HPLC method for analysis of different types of Brazilian green propolis extracts (glycolic and ethanolic). The method showed to be selective for the propolis phenolic markers. The analysis of variance and residues demonstrated that the method had significant linear regression, without lack of fit. It was also a precise, accurate and robust method, which was of utmost importance to analyze both glycolic and ethanolic extracts and at different concentrations. Moreover, as these products can display most complex matrices to analyze, a valid HPLC method can also prove to be specific and versatile.
