Objectives: To re-evaluate a sample of older adults enrolled in a randomized controlled trial of lithium for amnestic mild cognitive impairment (MCI) after 11 to 15 years, re-assessing their current (or last available) global cognitive and functional state. Methods: We recalled all former participants of the Lithium-MCI trial conducted by our group between 2009 and 2012 to perform a single-blinded, cross-sectional evaluation of their global clinical state to compare the long-term outcome of those who received lithium vs. those who received placebo. Results: Of the original sample (n=61), we were able to reach 36 participants (59% of retention), of whom 22 had previously received lithium (61% of the recall sample) and 14 (39%) had received placebo. Since 30.5% of the recalled sample was deceased, psychometric data were collected only for 69.5% of the participants. We found statistically significant differences in current mean Mini Mental State Examination score according to previous treatment group (25.5 [SD, 5.3] vs. 18.3 [SD, 10.9], p = 0.04). The lithium group also had better performance in the phonemic Verbal Fluency Test than the control group (34.4 [SD, 14.4] vs. 11.6 [SD, 10.10], p < 0.001). Differences in these measures also had large effect sizes, as shown by Cohen’s d values of 0.92 and 1.78, respectively. Conclusion: This data set suggests that older adults with amnestic MCI who had been treated with lithium during a previous randomized controlled trial had a better long-term global cognitive outcome than those from a matched sample who did not receive the intervention.

ABSTRACT The use of ultra-coarse droplets for herbicide application reduces the risk of drift but may compromise the coverage and efficacy of the treatment. The objective of this work was to evaluate the use of ultra-coarse droplets, in different spray volumes, in the application of dicamba herbicide in association with glyphosate, for the control of weeds in two field trials. The first trial was conducted in a 5 x 2 factorial design, with five spray volumes (58, 72, 96, 144, and 177 L ha-1) and two air induction flat-fan spray tips (MUG 110015 - MagnoJet and TTI 110015 - Teejet). The control efficiency of Commelina benghalensis and the spray deposition on the target were evaluated by detecting a tracer using spectrophotometry. The second was conducted in a 2 x 2 factorial scheme, using two volumes (100 and 125 L ha-1) and two tips (MUG 11002 and TTI 11002). The control efficiency of Conyza spp. and fresh matter were evaluated. The different spray volumes and tips did not differ in relation to the deposition of the tracer. The use of ultra-coarse droplets was adequate for weed control. The TTI and MUG tips gave similar and adequate control performance starting at 96 L ha-1. Increasing the volume above 100 L ha-1 did not result in better control.

Abstract: COVID-19 rapidly spread across the world in an unprecedented outbreak with a massive number of infected and fatalities. The pandemic was heavily discussed and searched on the internet, which generated big amounts of data related to it. This led to the possibility of attempting to forecast coronavirus indicators using the internet data. For this study, Google Trends statistics for 124 selected search terms related to pandemic were used in an attempt to find which keywords had the best Spearman correlations with a lag, as well as a forecasting model. It was found that keywords related to coronavirus testing among some others, such as “I have contracted covid”, had high correlations (≥0.7) with few weeks of lag (≤4 weeks). Besides that, the ARIMAX model using those keywords had promising results in predicting the increase or decrease of epidemiological indicators, although it was not able to predict their exact values. Thus, we found that Google Trends data may be useful for predicting outbreaks of coronavirus a few weeks before they happen, and may be used as an auxiliary tool in monitoring and forecasting the disease in Brazil.

ABSTRACT Objective To analyze clinical and sociodemographic characteristics associated with death and hospitalization of healthcare workers due to COVID-19, in addition to calculating the incidence rates per profession. Methods A cross-sectional observational study using secondary open data from the State Health Department of Espírito Santo (ES), Brazil. The cases of COVID-19 in healthcare workers were recorded between February 27 and August 17, 2020, in Espírito Santo, excluding cases with missing information. Results Of the confirmed cases, 75.6% (n=9,191) were female. The overall case fatality rate was 0.27% and the general hospitalization rate was 0.99%. The clinical outcome of death and the occurrence of hospitalization were associated with male sex, age ≥50 years, higher education, fever, difficulty breathing, cough, cardiac comorbidity, diabetes and obesity (p<0.05). Only the occurrence of hospitalization was associated with case reported in the metropolitan region of Vitória, runny nose, sore throat, headache and renal comorbidity (p<0.05). The profession with the highest incidence rate was nurse (16,053.2 cases/100,000 nurses). Conclusion The study demonstrated high frequency of cases among women, low overall case fatality rate, and high incidence in nurses.

RESUMO Objetivos: Avaliar a resistência de união dos reparos com resina composta auto-adesiva Vertise Flow (Kerr) e uma resina composta convencional Filtek Z350 (3M ESPE) submetida à diferentes tratamentos de superfície. Métodos: Quarenta amostras foram divididas em quatro grupos: ZV (Filtek Z350 + Vertise Flow, sem tratamento prévio); ZAV (Z350 + Vertise Flow com tratamento prévio com Sistema Adesivo Universal Single Bond (3M ESPE)); ZAZ (Filtek Z350 + Filtek Z350 com tratamento prévio com Sistema Adesivo Universal Single Bond (3M ESPE)); VV (Vertise Flow + Vertise Flow, sem tratamento prévio).

Resultados: Os valores médios da resistência de união foram maiores, respectivamente, nos grupos: ZV (36,07 ± 37,63); ZAZ (24,04 ± 28,51); VV (19,39 ± 28,24) e ZAV (16,06 ± 15,66). A resistência de união dos reparos entre os grupos apresentou resultados satisfatórios. Conclusão: A resina composta auto-adesiva Vertise Flow parece ser uma alternativa viável e rápida para reparos em restaurações com resinas compostas.

ABSTRACT Objective: To evaluate the bond strength of repairs with the self-adhering flowable composite Vertise Flow (Kerr) and a conventional composite resin Filtek Z350 (3M ESPE) subjected to different surface treatments. Methods: Forty specimens were divided into four groups: ZV (Filtek Z350 + Vertise Flow, without prior treatment); ZAV (Z350 + Vertise Flow with prior treatment with Single Bond Universal Adhesive System (3M ESPE)); ZAZ (Filtek Z350 + Filtek Z350 with prior treatment with Single Bond Universal Adhesive System (3M ESPE)); VV (Vertise Flow + Vertise Flow, without prior treatment). After 15 days of storage, the specimens were subjected to microtensile tests (Kratos IKCL3-USB, SP, Brazil), with speed of 0.5 mm/min and 20kg load. For statistical analysis, ANOVA with Tukey tests were used (p < 5%). Results: The mean values of the bond strength were highest respectively in the groups: ZV (36.07 ± 37.63); ZAZ (24.04 ± 28.51); VV (19.39 ± 28.24) and ZAV (16.06 ± 15.66). The bond strength of the repairs between the groups presented satisfactory results. Conclusion: The self-adhesive composite resin Vertise Flow seems to be a viable and fast alternative for composite resins repairs.

Abstract The Euphobia milii var. hislopii latex has been tested in the control of schistosomiasis but its action in the locomotor activity of Biomphalaria glabrata is unknown. The objective of this work was to study the locomotor and reproductive behaviors of B. glabrata exposed to E. milii var. hislopii latex. For this, 96 snails were individually exposed to the latex (LC50 - 0.53 mg / L) for 24 hours. The specimens were submitted to biomonitoring for image analysis to record the locomotor parameters at different times: before exposure (control), one day post exposure (group 1 d-p-e) and 30 days post exposure (group 30 d-p-e). The reproductive parameters were recorded weekly for 10 weeks. All locomotor activities of group 1 d-p-e decreased significantly. The egg/egg mass ratio decreased the week after exposure while there was an increase in the hatching rate. After 30 days, these reproductive parameters were similar to those observed in these same snails before exposure. However, the number of hatched snails declined after exposure until the end of the experiment. The influence of the latex in the parameters of B. glabrata added further evidence that this natural water-soluble product can be an important tool for the control of schistosomiasis.

Abstract Background: Injection of Hylan G-F20 (HY) into joints may provoke local flares, which mechanisms may involve reaction to protein contaminants. We have previously developed a protein-free saline-soluble galactomannan derived from guar gum (GM) that displays both analgesia and chondroprotection in experimental osteoarthritis (OA). We now demonstrate that both GM and Hylan G-F20 (HY) promote mild synovitis with cytokine release after intra-articular injection. Methods: Mice received 100 μg/25 μL GM or HY or saline into the knees. Joint pain was evaluated using von Frey test; cell influx, interleukin (IL)-1, IL-6, and CXCL-1 (pg/mL) levels were assessed in joint lavage at 6 h. Synovia were excised for histopathology. Results: Neither GM nor HY after being given into mice knee joints induced pain albeit promoting mild cell influx into joint washings as well as mild synovitis at histology, with no damage to the underlying cartilage. HY but not GM promoted IL-1 release into mice joints. Both compounds induced IL-6 and CXCL-1 release. Conclusion: Intra-articular injection of HY or GM promote acute transient synovitis whilst not provoking detectable significant joint damage. Local administration of these polysaccharides induces acute intra-articular release of inflammatory cytokines, which may account for joint flares following viscosupplementation.

RESUMO Objetivo: Testar a validade de construto, a confiabilidade e o erro de medida da versão em português do Brasil do questionário Manchester Respiratory Activities of Daily Living (MRADL) em pacientes com DPOC. Métodos: Avaliamos 50 pacientes com DPOC, 30 dos quais eram homens. A média de idade foi de 64 ± 8 anos, e a mediana do VEF1 em porcentagem do previsto (VEF1%previsto) foi de 38,4% (intervalo interquartil: 29,1-57,4%). A função pulmonar e limitações experimentadas durante a realização de atividades cotidianas foram avaliadas por meio de espirometria e da aplicação presencial do MRADL, respectivamente. Para a análise de validade de construto, testamos a hipótese de que haveria correlações moderadas entre a pontuação total no MRADL e parâmetros espirométricos. Analisamos a confiabilidade e o erro de medida entre avaliadores e entre teste e reteste. Resultados: Houve correlações moderadas e estatisticamente significativas entre a pontuação total no MRADL e VEF1/CVF, VEF1 em litros, VEF1%previsto e CVF%previsto (r = 0,34, r = 0,31, r = 0,42 e r = 0,38, respectivamente; p < 0,05 para todas). No tocante à confiabilidade e ao erro de medida para a pontuação total no MRADL entre avaliadores e entre teste e reteste, respectivamente, foram obtidos os seguintes valores: coeficiente de correlação intraclasse de duas vias e efeitos mistos para medidas únicas = 0,92 (IC95%: 0,87-0,96) e 0,89 (IC95%: 0,81-0,93); erro-padrão de medida do tipo concordância = 1,03 e 0,97; mínima mudança detectável no indivíduo = 2,86 e 2,69; mínima mudança detectável no grupo = 0,40 e 0,38; limites de concordância = −2,24 a 1,96 e −2,65 a 2,69. Conclusões: Em pacientes com DPOC, a versão brasileira do MRADL apresenta validade de construto satisfatória, confiabilidade interavaliadores/teste-reteste satisfatória e erro de medida interavaliadores/teste-reteste indeterminado.

ABSTRACT Objective: To test the construct validity, reliability, and measurement error of the Brazilian Portuguese-language version of the Manchester Respiratory Activities of Daily Living (MRADL) questionnaire in patients with COPD. Methods: We evaluated 50 patients with COPD, among whom 30 were men, the mean age was 64 ± 8 years, and the median FEV1 as a percentage of the predicted value (FEV1%predicted) was 38.4% (interquartile range, 29.1-57.4%). Pulmonary function and limitations in activities of daily living (ADLs) were assessed by spirometry and by face-to-face application of the MRADL, respectively. For the construct validity analysis, we tested the hypothesis that the total MRADL score would show moderate correlations with spirometric parameters. We analyzed inter-rater reliability, test-retest reliability, inter-rater measurement error, and test-retest measurement error. Results: The total MRADL score showed moderate correlations with the FEV1/FVC ratio, FEV1 in liters, FEV1%predicted, and FVC%predicted, all of the correlations being statistically significant (r = 0.34, r = 0.31, r = 0.42, and r = 0.38, respectively; p < 0.05 for all). For the reliability and measurement error of the total MRADL score, we obtained the following inter-rater and test-retest values, respectively: two-way mixed-effects model intraclass correlation coefficient for single measures, 0.92 (95% CI: 0.87-0.96) and 0.89 (95% CI: 0.81-0.93); agreement standard error of measurement, 1.03 and 0.97; smallest detectable change at the individual level, 2.86 and 2.69; smallest detectable change at the group level, 0.40 and 0.38; and limits of agreement, −2.24 to 1.96 and −2.65 to 2.69. Conclusions: In patients with COPD in Brazil, this version of the MRADL shows satisfactory construct validity, satisfactory inter-rater/test-retest reliability, and indeterminate inter-rater/test-retest measurement error.

ABSTRACT Introduction Penile cancer (PC) occurs less frequently in Europe and in the United States than in South America and parts of Africa. Lymph node (LN) involvement is the most important prognostic factor, and inguinal LN (ILN) dissection can be curative; however, ILN dissection has high morbidity. A nomogram was previously developed based on clinicopathological features of PC to predict ILN metastases. Our objective was to conduct an external validation of the previously developed nomogram based on our population. Materials and methods We included men with cN0 ILNs who underwent ILN dissection for penile carcinoma between 2000 and 2014. We performed external validation of the nomogram considering three different external validation methods: k-fold, leave-one-out, and bootstrap. We also analyzed prognostic variables. Performance was quantified in terms of calibration and discrimination (receiver operator characteristic curve). A logistic regression model for positive ILNs was developed based on clinicopathological features of PC. Results We analyzed 65 men who underwent ILN dissection (cN0). The mean age was 56.8 years. Of 65 men, 24 (36.9%) presented with positive LNs. A median 21 ILNs were removed. Considering the three different methods used, we concluded that the previously developed nomogram was not suitable for our sample. Conclusions In our study, the previously developed nomogram that was applied to our population had low accuracy and low precision for correctly identifying patients with PC who have positive ILNs.

RESUMO Introdução: A dificuldade na obtenção de resultados previsíveis é um grande desafio atual da cirurgia corretiva de estrabismo. Os resultados não desejados podem ocorrer em cerca de 51% dos procedimentos e a dificuldade pode ser devida ao fato da cirurgia ser realizada sobre tecidos perioculares bastante moles e com difícil referência para a localização anatômicas das estruturas. Objetivo: Identificar e analisar as principais causas responsáveis por reoperações nos usuários submetidos à cirurgia corretiva de estrabismo, atendidos no Centro de Oftalmológico do HUUFMA, em São Luís-MA. Métodos: Estudo do tipo pesquisa documental retrospectiva dos registros institucionais, por meio da coleta de dados dos prontuários físicos e eletrônicos no sistema ambulatorial interno do HUUFMA. Resultados: A taxa de reoperação analisada foi de 7,31%. Foram operados 89 pacientes menores de 15 anos (72,35%), 23 na faixa de 15 a 30 anos (18,69%) e 11 pacientes maiores de 30 anos (8,94%). A média da idade dos 123 operados foi de 10,32 anos. O sexo feminino foi prevalente na população (58,53%). Conclusão: O desvio Esotrópico (ET) foi o tipo de desvio mais comum no grupo de reoperados. Os resultados inesperados e os maiores desvios foram nos pacientes com relatos de comorbidades e/ou síndromes associadas ao estrabismo, assim como o desvio horizontal congênito (Dhc) foi prevalente entre as queixas apresentadas. A anestesia geral foi mais relatada em pacientes de menor faixa etária. O tempo médio decorrido entre a primeira e a segunda cirurgia foi de 10,54 meses e houve relativa prevalência das subcorreções nas reoperações.

ABSTRACT Introduction: The difficulty in obtaining predictable results is a great challenge on the strabismus surgery field. Procedures can lead to an undesirable development in about 51% of patients, and this difficulty may be due to surgery being perfomed on soft periocular tissues in which anatomical structure can be tricky to locate. Objective: Identify and analyse the main causes of reoperation on strabismus surgery patients treated at Centro Oftamológico do HUUFMA, in São Luís-MA. Methods: A retrospective documental research based on institutional registries, through data collection from physical and eletronic patient records of HUUFMA’s ambulatorial internal system. Results: The analysed reoperation rates were in about 7,31%. 89 patients under 15-year-old (72,35%), 23 patients aged between 15 to 30 (18,69%), and 11 patients over the age of 30 (8,94%) were submitted to surgery, with total number of 123 patients and mean age of 10,32 years. Female patients have prevailed in the population (58,53%). Conclusion: Esotropic deviation was the most common deviation in the reoperated group. The unexpected results and greatest deviations occurred on patients with reported comorbidities and/or syndromes associated with strabismus, such as dissociated horizontal deviation (DHD), which was prevalent among the presented complaints. General anesthesia was most reported in lower age patients. The average time elapsed between the first and the second procedure was 10,54 months, and a relative prevalence of the undercorrections occurred on reoperations procedures.

Resumo A avaliação em orientação profissional pode envolver diversos construtos, entre eles o da autoeficácia para escolha profissional, que se refere às crenças quanto à capacidade de se engajar em atividades de decisão profissional. Contudo, a literatura ainda é incipiente quanto a avaliação das fontes de autoeficácia em tal domínio. Assim, o presente estudo teve por objetivo a construção da Escala de Fontes de Autoeficácia para Escolha Profissional (EFAEP). O processo de construção envolveu a formulação dos itens e a coleta piloto. finalizado o processo de construção, deu-se início a coleta de dados, da qual participaram 388 estudantes das três séries do ensino médio, com idades entre 14 e 19 anos, de escolas públicas e particulares do interior do estado de São Paulo. Além da EFAEP, os alunos também responderam à Escala de Autoeficácia para Escolha Profissional (EAE-EP). Análises de componentes principais foram realizadas e uma estrutura com três fatores apresentou o melhor ajuste, com alfas de Cronbach variando entre 0,81 e 0,73. Além disso, todos os fatores da EFAEP se correlacionaram positivamente com os fatores da EAE-EP. Os resultados e limitações do estudo são discutidos de acordo com a literatura sobre o assunto.

Abstract Assessment in career counseling can involve various constructs, including that of career choice self-efficacy, which refers to one's belief in one's ability to engage in career decision-making activities. However, the literature is still incipient in relation to the assessment of the sources of self-efficacy for making career choices. Accordingly, the present study's aim was to develop the Career Choice Self-Efficacy Source Scale (Escala de Fontes de Autoeficácia para Escolha Profissional, or EFAEP; initials in Portuguese). The development process involved the formulation of the items as well as pilot data collection. Upon concluding the scale's developmental phase, we began data collection, which enjoyed the participation of 388 students between the ages of 14 and 19 years from public and private high schools in the state of São Paulo. In addition to the EFAEP, the students also responded to the Career Choice Self-Efficacy Scale (Escala de Autoeficácia para Escolha Profissional, or EAE-EP; initials in Portuguese). Principal component analysis was performed, and a three-factor structure exhibited the best fit, with Cronbach's alphas ranging between 0.81 and 0.73. Furthermore, all of the EFAEP's factors displayed positive correlations with the EAE-EP's factors. The study's results and limitations are discussed in relation to the literature on the subject.

Resumo Fundamento: Os suportes vasculares bioabsorvíveis (SVB) foram desenvolvidos com o intuito de melhorar os resultados da intervenção coronária percutânea a longo prazo, restabelecendo-se a vasomotricidade. Objetivos: Reportar o seguimento muito tardio do implante do SVB eluidor de everolimus Absorb® (Abbot Vascular, Santa Clara, EUA) em nosso centro. Métodos: Estudo observacional, retrospectivo, em um único centro brasileiro, que incluiu 49 pacientes submetidos ao implante do SVB Absorb® entre agosto/2011 e outubro/2013. Foram analisados os desfechos de segurança e eficácia na fase hospitalar e bastante tardia (> 2 anos). Resultados: Todos os 49 pacientes completaram um seguimento mínimo de 2,5 anos, sendo o máximo de 4,6 anos. A média de idade foi 56,8 ± 7,6 anos, sendo 71,4% da população estudada do sexo masculino e 26,5% composta por diabéticos. Considerando a apresentação clínica, a grande maioria (94%) tinha angina estável ou isquemia silenciosa. Obteve-se sucesso do dispositivo em 100% dos casos e do procedimento, em 96%. A taxa de eventos cardiovasculares maiores foi de 4% aos 30 dias, de 8,2% em 1 ano, e de 12,2% em 2 anos, sem mais eventos até 4,6 anos. Houve 2 casos de trombose (1 subaguda e 1 tardia) até o último seguimento. Conclusões: Nesta análise preliminar, o uso do SVB Absorb® mostrou-se seguro e eficaz no seguimento bastante tardio. Faz-se necessário estabelecer o perfil de eficácia e segurança destes dispositivos em cenários de maior complexidade.

Abstract Background: Bioresorbable vascular scaffolds (BVS) were developed to improve the long-term results of percutaneous coronary intervention, restoring vasomotion. Objectives: To report very late follow-up of everolimus-eluting Absorb BVS (Abbott Vascular, Santa Clara, USA) in our center. Methods: Observational retrospective study, in a single Brazilian center, from August 2011 to October 2013, including 49 patients submitted to Absorb BVS implantation. Safety and efficacy outcomes were analyzed in the in-hospital and very late follow-up phases (> 2 years). Results: All 49 patients underwent a minimum follow-up of 2.5 years and a maximum of 4.6 years. Mean age was 56.8 ± 7.6 years, 71.4% of the patients were men, and 26.5% were diabetic. Regarding clinical presentation, the majority (94%) had stable angina or silent ischemia. Device success was achieved in 100% of cases with 96% overall procedure success rate. Major adverse cardiovascular events rate was 4% at 30 days, 8.2% at 1 year, and 12.2% at 2 years, and there were no more events until 4.6 years. There were 2 cases of thrombosis (1 subacute and 1 late). Conclusions: In this preliminary analysis, Absorb BVS showed to be a safe and effective device in the very late follow-up. Establishing the efficacy and safety profiles of these devices in more complex scenarios is necessary.
