Abstract Objective: to identify the sociodemographic profile and the characteristics of interpersonal violence against older adults during the first year of the COVID-19 pandemic in a capital city from the Brazilian Southeast region. Method: a descriptive and exploratory research study with a cross-sectional design based on the notifications of suspected or confirmed cases of violence against older adults between March 2020 and March 2021. A univariate statistical analysis and Fisher’s exact test (p<0.05) were performed. Results: a total of 2,681 notifications were recorded during the period. The main victims were individuals aged between 60 and 64 years old, female, white-skinned and with low schooling levels. The instances of violence were more frequent in the victims’ homes. Physical and psychological violence predominated, through physical force/beatings and threats, respectively. Most of the aggressors were male, younger than the victims and generally their children or intimate partners. The aggressions were perpetrated more than once and were driven by generational conflicts. There was low referral to entities for the protection of older adults. Conclusion: the sociodemographic profile found evidences vulnerable victims, subjected to many types of violence, and at a potential risk against their overall health.

ABSTRACT Purpose Our objective was to investigate the prevalence of SWA, associated factors, relationship with STIs, and behavioral aspects in men attended at Referral Centers for STIs and acquired immunodeficiency syndrome (AIDS)/CR-STI/AIDS in northeast Brazil. Materials and Methods In this cross-sectional study, a questionnaire with sociodemographic, clinical, sexual and SWA practices information was applied to 400 men attended at two CR-STI/AIDS in Northeast Brazil on the years of 2018 and 2019. Clinical and laboratory diagnoses of STIs were confirmed in medical records. Logistic regression models were performed to identify the independent predictors for SWA. Results The prevalence of SWA over total samples was 15.00%. Of the participants, 239 (59.75%) of the participants were diagnosed with STIs, and of these 37 (15.48%) reported SWA. Most men practiced SWA in adolescence, being the last episode more than 20 years ago, usually with asinine and mules, in vaginal route and without a condom. SWA practitioners have higher percentages of occurrence of some viral STIs. SWA was associated with increasing age, history of residence in a rural area with remained over 12 years, married or widowed/separated, heterosexuals, with less than 7 years of study, Catholics, with hepatitis B, former user of alcoholic beverages and smokers, with a history of STI and intercourse with sex workers. Conclusion SWA practices increase STIs vulnerability. The association between hepatitis B and SWA highlights the importance of educational campaigns and conclusive studies on the topic.

Resumo O objetivo deste trabalho foi avaliar o perfil químico e sensorial, bem como a aceitabilidade, de espécies brasileiras de baunilhas. As espécies de baunilhas avaliadas foram: Vanilla planifolia, Vanilla chamissonis, Vanilla bahiana, and Vanilla pompona. Para tanto, foram utilizados a metodologia do perfil descritivo otimizado, testes de aceitação de consumidores por meio da aplicação dos extratos a chás e cremes, e análise de espectrometria de massa por meio de cromatografia gasosa. Foram identificados compostos voláteis, tais como vanilina, acetato de anisila, 4-metil-guaiacol, p-cresol, álcool benzílico e 2,3-butanodiol. As espécies V. planifolia e V. pompona apresentaram maiores intensidades de aroma de baunilha, aroma floral, aroma frutado, sabor de baunilha, cor marrom e gosto doce. Além disso, V. bahiana mostrou maior intensidade do atributo amadeirado, enquanto V. chamissonis mostrou atributos com menor intensidade. O chá de baunilha da espécie V. pompona teve melhor aceitação pelos consumidores. Entretanto, quando as baunilhas foram aplicadas a cremes, houve aceitação por mais de 80% dos consumidores de todas as amostras. As baunilhas nativas brasileiras apresentam diferentes perfis sensoriais e de compostos voláteis, além de potencial para alta aceitação pelo consumidor.

Abstract The objective of this work was to evaluate the chemical and sensory profile, as well as the acceptability, of Brazilian vanilla species. The evaluated vanilla species were Vanilla planifolia, Vanilla chamissonis, Vanilla bahiana, and Vanilla pompona. For this, the optimized descriptive profile methodology, consumer acceptance tests with extracts applied to teas and creams, and the analysis of mass spectrometry by gas chromatography were used. Volatile compounds, such as vanillin, anisyl acetate, 4-methyl guaiacol, p-cresol, benzyl alcohol, and 2,3-butanediol, were identified. The species V. planifolia and V. pompona exhibited a more intense vanilla aroma, floral aroma, fruity aroma, vanilla flavor, brown color, and sweet taste. In addition, V. bahiana showed a more intense woody attribute, while V. chamissonis showed less intense attributes. Vanilla tea from V. pompona had a better consumer acceptance. However, when the vanillas were applied to creams, there was an acceptance rate of over 80% of all samples. Brazilian native vanillas have different sensory and volatile profiles, besides potential for a high acceptance by consumers.

Abstract Background: Lupus nephritis (LN) is a major source of morbidity and mortality in patients with systemic lupus erythematosus (SLE), with 10–25% of patients progressing to end-stage renal disease (ESRD). Objective: This study aims to elucidate the predictive capabilities of 24-h proteinuria (24PTU) and serum creatinine (sCr) after 12 months of treatment with respect to long-term renal outcomes in LN in a single-center cohort of LN patients. Methods: A retrospective analysis was performed on 214 patients diagnosed with LN followed in our center. Values of 24PTU and sCr were assessed at baseline and after 3, 6 and 12 months, and after 5 years and/or the last evaluation. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 for 3 months or longer. End-stage renal disease (ESRD) was defined as the need for permanent dialysis. Receiver operating characteristics curves (ROC) were used to test the best cut-off value of 24PTU and sCr at 12 months who predict bad long-term renal outcomes. Results: The mean follow-up period was 11.2 ± 7.2 years. The best cut-off values for 24PTU and sCr as predictor of CKD were, respectively, 0.9 g/24 h and 0.9 mg/dL. ROC curve for 24PTU had a slightly lower performance than ROC curve for sCr as predictor for CKD (PTU AUC = 0.68; sCr AUC = 0.70), but sensitivity and specificity were better for 24PTU (24PTU: sensitivity = 63.5%, specificity = 71.2%; sCr: sensitivity = 54.8%, specificity = 75.3%). When the outcome was ESRD the best cut-off points were 0.9 g/24hs and 1.3 mg/dL for 24PTU and sCr, respectively, and the curve performance was better for 24PTU (PTU AUC = 0.72; sCr AUC = 0.61). Conclusions: In this ethnically diverse population with LN followed for a long time (> 10 years), levels of 24PTU > 0.9/day at 12 months was a good predictor of bad long-term renal outcome. The serum creatinine > 0.9 mg/dL and > 1.3 mg/dL at 12 months were also good predictors of CKD and ESRD, respectively. Patients with 24PTU < 0.9 g/day and sCr < 1.3 mg/dL at 12 months are not likely to develop ESRD because of the high negative predictive values (NPV) (93.2% and 82%). 24PTU and sCr are relevant as components for a treat-to-target strategy for LN treatment, since their high NPV corroborates their importance as good predictors of long-term renal outcome.

Resumo: Estudos sobre a saúde mental de atletas de alto rendimento vêm crescendo internacionalmente, porém a produção nacional ainda é limitada. Esta revisão sistemática tem como objetivo mapear a produção do conhecimento sobre saúde mental desses atletas, seguindo a diretriz PRISMA para revisões sistemáticas. Encontramos aumento no número de publicações nos últimos cinco anos, com predomínio de publicações por autores de países de língua inglesa (EUA, Inglaterra/Reino Unido e Austrália) focando principalmente nos transtornos mentais mais comuns (ansiedade, depressão, distúrbio de sono, uso de álcool). Verificamos que atletas de elite têm taxas similares ou mais elevadas de transtornos mentais do que a população em geral. O esporte coletivo de invasão e o esporte individual de marca aparecem como os mais pesquisados. Este estudo avança com o debate sobre a saúde mental em atletas de alto rendimento e chama a atenção de pesquisadores, gestores e psicólogos brasileiros para essa temática.

Abstract: Studies on the mental health of elite athletes have been growing internationally. However, Brazilian contribution to this theme is still limited. This systematic review aims to map the studies on the mental health of elite athletes, following the PRISMA guidelines for systematic reviews. We found an increase in the number of publications in the last five years, with a predominance of publications by authors from English-speaking countries (USA, England/UK and Australia) focusing mainly on the most common mental disorders (anxiety, depression, sleep disorder, use of alcohol). We found that elite athletes have similar or higher rates of mental disorders than the general population. Team sports and athletic individual sports appear as the most investigated. This study advances the debate on mental health in elite athletes and draws the attention of Brazilian researchers, managers and psychologists to this theme.

ABSTRACT Purpose: to analyze the use of digital resources by Brazilian phonoaudiologists before and during the period of the COVID-19 pandemic. Methods: cross-sectional study carried out with a representative sample of Brazilian phonoaudiologists, with at least one year of practical experience. An online questionnaire consisting of 28 questions divided into eight sections was prepared. Data were analyzed and are reported as absolute and relative frequency regarding the variables: respondent’s age, highest degree and years of experience; weekly working hours; region of the country; type of service and area of expertise; use of digital means before and during the pandemic and willingness to use the same kind of resource after the pandemic. Results: telehealth technologies were used by 90% of phonoaudiologists in Brazil since before the COVID-19 pandemic. A change in the profile of technologies used was observed: after the pandemic, videoconferences gained more use in contact with patients compared to the pre-pandemic period even though contact via mobile phone and instant messaging applications are the most used, both before and during the pandemic. Conclusion: the study's findings demonstrate that 90% of phonoaudiologists who answered the questionnaire in Brazil used and still make use of telehealth technologies to contact patients.

Abstract Objective: To evaluate the efficacy of silver diamine fluoride (SDF) in arresting dentin caries lesions when applied under different concentrations and times. Material and Methods: Forty-two bovine blocks were selected and fixed in 24-well plates. Each well received a mixed bacterial inoculum added to the culture medium with 5% sucrose. The plates were incubated in microaerophilia (7 days) for caries formation, confirmed by micro-CT (M1). SDF was applied over the carious lesions for different times and concentrations (n=6): SDF 30% - immediate removal, 1 minute and 3 minutes; SDF 38%, - immediate removal, 1 minute and 3 minutes. The group without treatment was the control. Then, the samples were again scanned by micro-CT (M2) and submitted to a second cariogenic challenge for 21 days. Then, a final scan was performed (M3). Results: Mean pH at the culture medium and lesion depth were compared using Kruskal-Wallis and Wilcoxon tests. 38% SDF showed the lowest metabolic activity of the biofilm. All 38% groups and 30% 1 and 3 minutes did not show an increase in mean lesion depth comparing M3 with M1. However, only 30% 3 minutes and 38% 1 and 3 minutes showed a significant reduction of lesion depth. Conclusion: The minimum application time of 30% SDF to arrest dentin caries lesion was 1 minute, while 38% SDF arrested with application and immediate removal.

Abstract Objective Analyze the characteristics associated with the parents of children and adolescents who have heard about the human papillomavirus, as well as the knowledge about the infection and the intention to vaccinate their children. Methods Cross-sectional study with quantitative approach, conducted through a structured interview. We interviewed 376 parents of children and adolescents who were awaiting pediatric care at health services in Três Lagoas/MS. The collected data (sociodemographic characteristics; reproductive and sexual characteristics; knowledge about human papillomavirus and intention to vaccinate the child) were analyzed using descriptive statistics, Fisher’s exact test or the chi-square association test and Student’s t-test. Results Among the respondents, 327 (87.0%) said they had heard about the human papillomavirus. An association was identified between parents who had never heard of the infection and male sex, age between 18 and 25 years and unfinished primary education. Among the parents who had heard about the human papillomavirus, 152 (46.5%) stated that it is a sexually transmitted infection, 245 (74.9%) assured that the transmission occurs through unprotected sexual intercourse, 275 (75.5%) are unaware of its signs and symptoms, 218 (66.7%) mistakenly stated that this infection is curable and 283 (86.5%) know of the existence of the vaccine. Among all respondents, 98.1% would take their child to get vaccinated against the virus. Conclusion Gaps were observed in the knowledge of the parents of children and adolescents about the human papillomavirus, showing the need for health education and dissemination of actions to cope with the infection in the media and social networks.

Abstract Aim: To analyze the concepts of mental health and illness as well as the instruments used to measure them in the elite athlete. Methods: The scoping review was conducted using PubMed, SPORTDiscus, PsycINFO, and Scielo. The keywords “Mental Health” AND “Sport” AND “Athlete” were used to find studies in peer-reviewed scientific journals published in English, Spanish, and Portuguese. Studies went through four stages of analysis according to PRISMA guidelines. A total of 179 records were included in this review. Results: Recent studies suggest that health and illness should not be recognized as deviations from the norm, but as a changing construct, varying on a continuum, where, at one extreme, we have health; and, at the other, we have illness even coexisting in an orthogonal way. Between the two extremes, there are degrees of psychological well-being and distress, leading from reduced functioning to effective functioning. This indicates the need for psychological support for both the maintenance and enhancement of mental health. An alarming result was that, although most of the studies investigated mental health, they used primarily instruments focused on illness. This new perspective of health-illness brings the need for the development of new instruments that encompass protective factors and symptom screening. Conclusions: We reinforce the need for a paradigm shift in relation to the mental health of elite athletes understanding it as a changing construct that should be constantly improved and/or maintained. This change led to the need for broader assessment instruments that encompass protective factors and illness symptoms.

Abstract The aim of this study was to characterize the salivary metabolomic profile in adolescents with juvenile systemic lupus erythematosus (jSLE). A total of 24 adolescents with jSLE (15.92 ± 2.06 years) and 12 systemically healthy controls (15.25 ± 2.7 years) were included in the study. Participants underwent rheumatologic testing and periodontal examination, with the recording of plaque index (PI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing index (BPI). Unstimulated whole saliva was collected from both groups and stored at -80 ºC. The salivary proton nuclear magnetic resonance (1H-NMR) spectra were acquired in a spectrometer operating at 500 MHz. Partial least squared discriminant analysis (PLS-DA) and orthogonal PLS-DA (O-PLS-DA) were used for statistical analysis. Mean CAL and PI were significantly increased in the group with jSLE (p < 0.01). Patients with jSLE presented a significantly different salivary metabolic profile (accuracy = 0.54; R2 = 0.86; Q2 = -0.293), significantly higher salivary levels of N-acetyl sugars, and significantly reduced levels of phenylalanine, glycine, taurine, hydroxybutyrate, and valerate compared with healthy controls (p < 0.05). It is suggested that the salivary metabolomic profile analyzed by 1H NMR in patients with jSLE presents a different fingerprint that the systemically healthy subjects. Integrating the variation of metabolites with the identification of the metabolic pathways involved seems to provide a better understanding of the influence of systemic disease on salivary metabolites.

ABSTRACT The chronic hepatitis C (CHC) treatment is currently based on the use of direct-acting antivirals (DAAs), and patients infected with hepatitis C virus genotype 3 (GT3) have emerged as a more difficult-to-cure population. The NS5A inhibitor daclatasvir (DCV) and sofosbuvir (SOF), an NS5B viral polymerase inhibitor, are among the drugs that compose more effective and safer treatment regimens. The virus genetic variability is related to resistance-associated substitutions (RASs) that adversely impact DAAs effectiveness. The aims of this study were to analyze the association of NS5A and NS5B RASs and other clinical factors with DAAs regimens effectiveness in patients with GT3 CHC infection. This was a prospective cohort study performed in a Brazilian university hospital. Individuals older than 18 years with GT3 CHC treated with SOF + DCV ± ribavirin (RBV) or SOF + peginterferon (PEG) + RBV were included. Blood samples were collected at baseline and post-treatment. A total of 121 patients were included. Sustained virological response rates were 87.6% for the SOF + DCV ± RBV group and 80.0% for the SOF + PEG + RBV arm. Cirrhosis, prior treatment with interferon/PEG + RBV, and baseline NS5A RAS were associated with higher risk of treatment failure. The NS5A analysis suggested that A30K, Y93H, and RAS at site 62 were related to failure. Interestingly, a likely compensatory effect was shown between A30K and A62T. Emergence of Y93H was always associated with RAS at position 62. The RASs dynamics comprehension is an important tool to indicate more effective treatment for GT3 patients.

RESUMO A recente detecção de material genético (RNA) do novo coronavírus em amostras de fezes e no esgoto aponta para a possibilidade de se identificar a circulação do vírus e até mesmo estimar o número de pessoas infectadas em determinada região pelo monitoramento sistemático do esgoto, configurando-se em importante ferramenta epidemiológica de testagem massiva indireta, incluindo portadores sintomáticos e assintomáticos. Nesse sentido, concebeu-se um projeto para a detecção e a quantificação do novo coronavírus em amostras de esgoto coletadas em 15 sub-bacias de esgotamento sanitário dos ribeirões Arrudas e Onça, visando entender a dinâmica de circulação e a prevalência do vírus nas regiões investigadas. Tais sub-bacias esgotam os efluentes gerados por uma população da ordem de 1,5 milhão de pessoas no município de Belo Horizonte e parte de Contagem. O plano de amostragem contemplou 17 pontos (15 sub-bacias + afluente às 2 estações de tratamento de esgoto) de monitoramento semanal, com coletas compostas durante todo o período da manhã. A detecção e a quantificação do RNA viral efetuaram-se em laboratório por meio de ensaios de RT-qPCR. Os resultados obtidos em quatro semanas de monitoramento (semanas epidemiológicas 21 a 24) mostraram um incremento da ocorrência do vírus, atingindo 100% das regiões investigadas na semana epidemiológica 24. A estimativa da população infectada pelo novo coronavírus pelo monitoramento do esgoto em Belo Horizonte apresentou tendência de crescimento exponencial, sendo até 20 vezes maior do que o número de casos confirmados acumulados. Quanto à circulação do vírus, as concentrações do RNA viral têm se mostrado bastante variáveis nas regiões monitoradas, com maiores porcentagens de população infectada estimada ao norte e nordeste da capital mineira.

ABSTRACT The recent detection of SARS-CoV-2 RNA in stool and sewage samples highlights the possibility of mapping the circulation of the virus and even estimating the number of infected people through the systematic monitoring of sewage in a specific region. Therefore, this is an important epidemiological tool for large-scale indirect testing, including symptomatic and asymptomatic carriers. This project was conceived for the detection and quantification of the SARS-CoV-2 in sewage samples collected in 15 watersheds of the Arrudas and Onça streams, aiming to understand the dynamics of spread and the prevalence of the virus in these regions/watersheds. These sub-basins exhaust the effluents generated by a population of approximately 1.5 million people in the municipality of Belo Horizonte and part of Contagem. Weekly composite samples were collected during the morning periods in seventeen monitoring points (15 water sheds + influent to 2 sewage treatment plants). RNA detection and quantification were performed in the laboratory using RT-qPCR. The results obtained in four weeks of monitoring (epidemiological weeks 21 to 24) showed an increase in the occurrence of the virus, reaching 100% of the monitored regions investigated in epidemiological week 24. The infected population, estimated by sewage monitoring in Belo Horizonte, showed exponential growth, being up to 20 times higher than those of accumulated confirmed cases. As for the dynamics of virus spread, RNA concentrations have shown to be quite variable in the monitored regions with higher percentages of the estimated infected population in the northern and north-eastern portions of Belo Horizonte.

RESUMO Introdução: O surgimento de lesão renal aguda (LRA) em pacientes com síndrome nefrótica (SN) requer diagnóstico imediato e diferenciação entre necrose tubular aguda (NTA) e glomerulonefrite proliferativa. Avaliamos o uso potencial de testes de biomarcadores urinários comerciais no diagnóstico de LRA em pacientes com SN. Métodos: Uma estimativa transversal das concentrações urinárias de KIM-1 e NGAL foi realizada em 40 pacientes com SN: 9 com glomerulopatia proliferativa, sendo 4 com LRA e 31 sem glomerulopatia proliferativa, sendo 15 com LRA. A LRA foi definida usando os critérios da KDIGO. Resultados: A média de idade foi de 35 ± 16 anos. Os principais diagnósticos foram glomeruloesclerose segmentar e focal (10, 25%), glomerulopatia membranosa (10, 25%), doença por lesão mínima (7, 18%), nefrite lúpica (6, 15%) e glomerulonefrite proliferativa (3, 8 %). Os pacientes com NTA apresentaram níveis mais elevados de KIM-1 urinário (P = 0,0157) e NGAL (P = 0,023) do que pacientes sem NTA. As concentrações urinárias de KIM-1 (P = 0,009) e NGAL (P = 0,002) foram maiores em pacientes com LRA do que em pacientes sem LRA. Os níveis urinários de NGAL e KIM-1 foram significativamente maiores em pacientes com NTA sem glomerulonefrite proliferativa do que em pacientes com glomerulonefrite proliferativa (P = 0,003 e P = 0,024, respectivamente). Conclusões: As estimativas de lipocalina associada a gelatinase de neutrófilos (NGAL) e molécula de lesão renal 1 (KIM-1) se correlacionaram com sinais histológicos de NTA, e foram capazes de discriminar pacientes com LRA mesmo em condições de SN. Além disso, os níveis urinários de NGAL e KIM-1 podem ser úteis no diagnóstico diferencial de necrose tubular aguda e glomerulonefrite exsudativa em pacientes com síndrome nefrótica.

ABSTRACT Introduction: Emergence of acute kidney injury (AKI) in patients with nephrotic syndrome (NS) requires prompt diagnosis and differentiation between acute tubular necrosis (ATN) and proliferative glomerulonephritis. We studied the potential use of commercial urinary biomarkers' tests in the diagnosis of AKI in patients with NS. Methods: A cross sectional estimate of urinary concentrations of KIM-1 and NGAL was performed in 40 patients with NS: 9 with proliferative glomerulopathy, being 4 with AKI and 31 without proliferative glomerulopathy, being 15 with AKI. AKI was defined using the KDIGO criteria. Results: The mean age was 35 ± 16 years. The main diagnoses were focal and segmental glomerulosclerosis (10, 25%), membranous glomerulopathy (10, 25%), minimal change disease (7, 18%), lupus nephritis (6, 15%), and proliferative glomerulonephritis (3, 8%). Patients with ATN had higher levels of urinary KIM-1 (P = 0.0157) and NGAL (P = 0.023) than patients without ATN. The urinary concentrations of KIM-1 (P= 0.009) and NGAL (P= 0.002) were higher in patients with AKI than in patients without AKI. Urinary NGAL and KIM-1 levels were significantly higher in patients with ATN without proliferative glomerulonephritis than in patients with proliferative glomerulonephritis (P = 0.003 and P=0.024, respectively). Conclusions: Neutrophil gelatinase associated lipocalin (NGAL) and kidney injury molecule 1 (KIM-1) estimates correlated with histological signs of ATN and were able to discriminate patients with AKI even in conditions of NS. Furthermore, urinary levels of NGAL and KIM-1 may be useful in the differential diagnosis of acute tubular necrosis and exudative glomerulonephritis in patients with nephrotic syndrome.
