Abstract Background: the biological activity of vitamin D depends on the activity of its receptor or VDR. On the other hand, the activity of this receptor is influenced by its state of methylation. The objective of this study was to verify if the BsmI polymorphism of the VDR gene influences its methylation profile in adolescents. Secondly, it was to verify if the status of some metabolic factors (oxidative stress, inflammation, lipid profile, and glycemia) in the serum, and gender-adjusted vitamin D levels are independent factors with an influence on the VDR methylation profile. Methods and results: the study included 198 adolescents of both sexes, aged 15-19 years, who underwent testing for VDR gene methylation polymorphisms, serum vitamin D levels, and metabolic, oxidative stress, and systemic inflammation markers. It was observed that the BB genotype was less methylated than the other groups (26.1 % versus 30.3 %, and 29.3 % for Bb and bb, respectively), although without statistical differences between them. The odds ratio indicated a protection of 13 % (partially methylated) for vitamin D status, while alpha glycols increased the risk ratio (of being partially methylated) by 3 %. MDA was protective at a 28 % chance of risk that adolescents with higher levels of lipid peroxidation would be hypomethylated. Conclusion: we conclude that the methylation profile of the VDR gene is not influenced by the different BsmI polymorphism genotypes, and that serum vitamin D and serum markers of oxidative stress and inflammation can modulate this profile.

Resumen Antecedentes: la actividad biológica de la vitamina D depende de la actividad de su receptor, el VDR. Por otro lado, la actividad de este receptor está influenciada por su estado de metilación. El objetivo de este estudio es verificar si el polimorfismo BsmI del gen VDR influye en el perfil de metilación del mismo en los adolescentes. En segundo lugar, verificar si los factores metabólicos (estrés oxidativo, inflamación, perfil lipídico y glucemia) del suero y la vitamina D ajustada por sexo actúan independientemente de los polimorfismos sobre el perfil de metilación del VDR. Métodos y resultados: el estudio incluyó a 198 adolescentes de ambos sexos, de 15 a 19 años de edad, que se sometieron a análisis de polimorfismos de metilación del gen VDR, niveles de vitamina D, marcadores metabólicos, estrés oxidativo e inflamación sistémica. Se observó que el genotipo BB estaba menos metilado que los otros grupos (26,1 % contra 30,3 % y 29,3 % para Bb y bb respectivamente), aunque sin diferencias estadísticas entre ellos. El odds ratio indicó una protección del 13 % (parcialmente metilado) para el estado de la vitamina D, mientras que los alfa glicoles aumentaron el índice de riesgo (de estar parcialmente metilado) en un 3 %. La MDA fue protectora con un 28 % de probabilidad de riesgo de que los adolescentes con niveles más altos de peroxidación lipídica fueran hipometilados. Conclusión: concluimos que el perfil de metilación del gen VDR no está influenciado por los diferentes genotipos del polimorfismo BsmI y que la vitamina D y los marcadores de estrés oxidativo e inflamación en el suero pueden modular este perfil.

Vitamin D is a fat-soluble vitamin that plays a role not only in calcium homeostasis, but also in several other functions, including cell growth and immune functions, and is considered a neurosteroid. Vitamin D deficiency is highly prevalent worldwide and has been suggested to be associated with an increased risk of emotional disorders. Therefore, the association between vitamin D levels and psychophysiological disorders, such as depression, anxiety, and mood, has been investigated. To list these variables, a bibliographical literature research was conducted in the MEDLINE/PubMed, Web of Science, Scopus, Science Direct and PsycINFO databases, between November and December 2020, with no year limits of publication. The studies involved humans aged between 18 and 59 years without associated diseases. This review presents evidence of the main variables involved in this association, main tools used to verify these variables, and methods used to verify circulating vitamin D levels in populations. Most studies have indicated that the main psychophysiological variables involved with vitamin D levels are depression and anxiety followed by mood, and an association has been observed between increased serum vitamin D levels and reduction in symptoms of depression, anxiety, and mood, and there is a heterogeneity of methods for assessing vitamin D. More studies are clearly needed to improve our understanding of their role in modulating the psychophysiological aspects of vitamin D levels.

Evidence shows that metabolic syndrome (MS) is associated with a greater risk of developing Parkinson's disease (PD) because of the increase in oxidative stress levels along with other factors such as neuroinflammation and mitochondrial dysfunction. However, because some studies have reported that MS is associated with a lower risk of PD, the relationship between MS and PD should be investigated. This study aimed to investigate the effect of MS on PD. Two authors searched five electronic databases, namely, MEDLINE, PubMed, Scopus, PsycINFO, Web of Science, and Science Direct, for relevant articles between September and October 2020. After screening the title and abstract of all articles, 34 articles were selected for full-text review. Finally, 11 articles meeting the eligibility criteria were included in the study. The quality of articles was critically evaluated using the Joanna Briggs Institute. Overall, we evaluated data from 23,586,349 individuals (including healthy individuals, with MS and PD) aged 30 years or more. In cohort studies, the follow-up period varied between 2 and 30 years. MS contributed considerably to the increase in the incidence of PD. In addition, obesity, a component of MS, alone can increase the probability of developing neurodegenerative diseases. However, despite few studies on MS and PD, changes in cognitive function and more rapid progression of PD disease has been documented in patients with MS using methods commonly used in research.

RESUMO Racional: Doenças inflamatórias intestinais − Doença de Crohn (DC) e Retocolite Ulcerativa (RCU) − são desordens crônicas associadas, por diversos fatores, a sintomas psicológicos e estigmatização dos portadores. Objetivo: Comparar indivíduos portadores e não portadores de doenças inflamatórias intestinais em relação à prevalência de ansiedade e depressão. Método: O aspecto psicológico foi analisado através de dois questionários mundialmente validados − o Questionário sobre Saúde do Paciente (PHQ-9) e o questionário de Transtorno Geral de Ansiedade (GAD-7) – além de um questionário sociodemográfico. A coleta foi realizada em três grupos, cada um composto por 100 indivíduos, sendo o primeiro composto por pacientes ambulatoriais com diagnóstico de doenças inflamatórias intestinais, o segundo por pacientes ambulatoriais sem diagnóstico de doenças inflamatórias intestinais e o terceiro por indivíduos não ambulatoriais sem diagnóstico de doenças inflamatórias intestinais. Resultados: Os grupos foram semelhantes quanto a gênero, etnia, estado civil e uso de tabaco. Quanto à classe social, o grupo doenças inflamatórias intestinais apresentou predominância de classe E (46%), o grupo Controle Ambulatorial predominância de classe D (44%) e o grupo Controle Parque de classe C (44%) (p < 0,001). O grupo controle parque teve também maior número de indivíduos jovens (média = 36,69 anos) (p < 0,001). Observou-se maior número de indivíduos com depressão e ansiedade nos grupos doenças inflamatórias intestinais e Controle ambulatorial em comparação ao grupo Controle parque (p < 0,001), mas sem diferença entre os primeiros. Houve maior número de indivíduos com ansiedade grau severo no grupo DII (36%) em comparação ao grupo Controle parque (8%) (p < 0,001). Conclusão: No grupo portador de doenças inflamatórias intestinais foi observada maior severidade e prevalência de ansiedade e depressão.

ABSTRACT Rationale: Inflammatory bowel diseases − Crohn's Disease (CD) and Ulcerative Colitis (UC) − are chronic disorders associated, for several reasons, with psychological symptoms and stigmatization of patients. Aim: To compare individuals with and without inflammatory bowel diseases in relation to the prevalence of anxiety and depression. Method: The psychological aspect was analyzed using two globally validated questionnaires − the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder questionnaire (GAD-7) − in addition to a sociodemographic questionnaire. Data collection was carried out in three groups, each one consisting of 100 individuals; the first comprising outpatients with a diagnosis of inflammatory bowel diseases, the second comprising outpatients without a diagnosis of inflammatory bowel diseases and the third by non-outpatients without a diagnosis of inflammatory bowel diseases. Results: The groups were similar regarding gender, ethnicity, marital status and tobacco use. As for social class, the IBD group showed a predominance of class E (46%), the outpatient group a predominance of class D (44%) and the non-outpatient group, class C (44%) (p < 0.001). The non-outpatient group also had a higher number of young individuals (mean = 36.69 years) (p < 0.001). There was a higher number of individuals with depression and anxiety in the IBD and outpatient control groups when compared to the non-outpatients’ group (p < 0.001), but with no difference between the two first groups. There was a higher number of individuals with severe degree anxiety in the IBD group (36%) compared to the non-outpatients’ group (8%) (p < 0.001). Conclusion: Greater severity and a prevalence of anxiety and depression were observed in the group with inflammatory bowel diseases.

Research in several areas is evaluating the extent of infection and kidney disorders related to the virus. The aim of this study is to describe the effects of COVID-19 on the renal system. Final considerations point to the main complications of the effects of infection and renal disorders caused by COVID-19, such as acute kidney injury and a consequent increase in the disease’s poor prognosis.

Resumo Senna rugosa (Fabaceae) é uma espécie comum do território brasileiro, especialmente no Cerrado. É amplamente utilizado na medicina popular, embora ainda não tenha sido investigada quanto aos seus fitoconstituintes e atividades farmacológicas. Neste estudo, foram realizadas as análises fitoquímicas preliminares do extrato etanólico de folhas de S. rugosa e sua citotoxicidade, atividade antitumoral e antimicrobiana (antibacteriana, antifúngica, anti-Trypanosoma e anti-Leishmania). O extrato bruto foi analisado em HPLC-DAD e as frações foram caracterizadas usando técnicas de GC-MS e ESI-MS. Os resultados indicam a presença majoritária de compostos fenólicos, incluindo flavonóis, antraquinonas e derivados de antronas. Atividades antimicrobianas foram detectadas contra as espécies Staphylococcus aureus, Pseudomonas aeruginosa, Candida famata, Candida krusei e Candida tropicalis. Além disso, uma fraca atividade anti-tripanossomatídeos contra as cepas M2269 e BH46 de Leishmania sp. Uma atividade antitumoral foi identificada, porém também foi observada uma toxicidade sobre células de fibroblastos (L929). Fitoquimicamente, os resultados fornecem evidências de que compostos fenólicos nas folhas de S. rugosa podem ser os responsáveis pela sua atividade antimicrobiana e pela toxicidade celular observada em nosso estudo.

Abstract Senna rugosa (Fabaceae) is a common specie of the Brazilian territory, especially in the Cerrado biome. It is widely used in the popular medicine although not yet adequately investigated as to its phytoconstituents and pharmacological activities. In this study, the preliminary phytochemical analysis of ethanolic leaf extract of S. rugosa was performed and its cytotoxicity, antitumoral and antimicrobial activities (antibacterial, antifungal, anti-Trypanosoma and anti-Leishmania) were evaluated. The crude extract was analyzed in HPLC-DAD and fractions were also characterized using GC-MS and ESI-MS techniques. Results indicate phenolic compounds majority presence, including flavonol, anthraquinone and anthrones derivatives. Relative antimicrobial activities were detected against Staphylococcus aureus, Pseudomonas aeruginosa, Candida famata, Candida krusei and Candida tropicalis. As well as, a weak anti-trypanosomatids activity against M2269 strain and BH46 strain of Leishmania sp. A relative antitumoral activity was also identified but in counterpoint were also observed a toxicity in fibroblast cells (L929). Phytochemically, results provide evidence that phenolic compounds in S. rugosa leaves might be the responsible for its antimicrobial activity and cell toxicity inferred in our research.

Abstract INTRODUCTION: Herein, we aimed to identify the factors associated with adverse drug events (ADEs) in chronic Chagas disease (CD) patients. METHODS: We analyzed 320 medical notes from 295 patients. The Naranjo algorithm was applied to determine the cause of ADEs. Mixed effects logistic regression was performed to evaluate the factors associated with ADEs. RESULTS: ADEs were described in 102 medical notes (31.9%). Captopril was most frequently associated with ADEs. Age (RR 0.96; 95%CI 0.94-0.99) and cardiac C/D stages (RR 3.24; 95%CI 1.30-4.58) were the most important clinical factors associated with ADEs. CONCLUSIONS: Close follow-up is warranted for CD patients.

Resumo O objetivo do presente estudo foi verificar se os padrões psicométricos da Escala de percepção, por professores, dos comportamentos agressivos de crianças na escola (EPPCACE) evidenciavam sua validade interna. No Estudo 1 (n = 210), foi realizada a adaptação do instrumento e executada uma análise fatorial exploratória. No Estudo 2 (n = 203), efetuou-se uma análise fatorial confirmatória. Participaram professores do ensino fundamental de escolas públicas e particulares. Esses responderam à EPPCACE e a perguntas sociodemográficas. Os resultados indicaram que o instrumento é composto por três fatores: Agressividade direcionada ao âmbito geral (α = 0,95), Comportamentos pró-sociais (α = 0,90) e Agressividade direcionada aos professores (α = 0,90). Conclui-se que a EPPCACE é válida e fidedigna, podendo auxiliar na avaliação do contexto escolar a partir da percepção do professor acerca do comportamento agressivo dos alunos.

Abstract The objective of this study was to verify whether the psychometric patterns of the Scale of teachers’ perception of aggressive behavior of children in school (EPPCACE) showed evidence of its internal validity. In Study 1 (n = 210) the instrument was adapted and an exploratory factorial analysis was performed. In Study 2 (n = 203) a confirmatory factorial analysis was performed. Elementary school teachers in public and private schools participated and answered the EPPCACE and sociodemographic questions. Results indicated that the instrument is composed of three factors: Aggressiveness directed to the general scope (α = 0.95), Pro-social behaviors (α = 0.90), and Aggressiveness directed to teachers (α = 0.90). We concluded that the EPPCACE is valid and reliable, and it can help in the evaluation of the school context from the teacher’s perception of the aggressive behavior of the students.

Abstract Background: There is still a need for new alternatives in pharmacological therapy for neglected diseases, as the drugs available show high toxicity and parenteral administration. That is the case for the treatment of leishmaniasis, particularly to the cutaneous clinical form of the disease. In this study, we present the synthesis and biological screening of eight 4-phenyl-1,3-thiazol-2-amines assayed against Leishmania amazonensis. Herein we propose that these compounds are good starting points for the search of new antileishmanial drugs by demonstrating some of the structural aspects which could interfere with the observed activity, as well as suggesting potential macromolecular targets. Methods: The compounds were easily synthesized by the methodology of Hantzsch and Weber, had their purities determined by Gas Chromatography-Mass spectrometry and assayed against the promastigote forms of Leishmania amazonensis as well as against two white cell lines (L929 and THP-1) and the monkey's kidney Vero cells. PrestoBlue® and MTT viability assays were the methodologies applied to measure the antileishmanial and cytotoxic activities, respectively. A molecular modeling target fishing study was performed aiming to propose potential macromolecular targets which could explain the observed biological behavior. Results: Four out of the eight compounds tested exhibited important anti-promastigote activity associated with good selectivity indexes when considering Vero cells. For the most promising compound, compound 6, IC50 against promastigotes was 20.78 while SI was 5.69. Compounds 3 (IC50: 46.63 μM; SI: 26.11) and 4 (IC50: 53.12 μM; SI: 4.80) also presented important biological behavior. A target fishing study suggested that S-methyl-5-thioadenosine phosphorylase is a potential target to these compounds, which could be explored to enhance activity and decrease the potential toxic side effects. Conclusions: This study shows that 4-phenyl-1,3-thiazol-2-amines could be good scaffolds to the development of new antileishmanial agents. The S-methyl-5-thioadenosine phosphorylase could be one of the macromolecular targets involved in the action.

Resumo Este artigo tem por objetivo determinar a prevalência e os fatores associados à infecção latente pelo Mycobacterium tuberculosis entre agentes comunitários de saúde (ACS), usando dois pontos de corte da prova tuberculínica 5mm e 10mm. Trata-se de estudo transversal, com dados coletados sobre sexo, idade, cicatriz de BCG, prova tuberculínica (PT) anterior, tempo que trabalha na profissão de ACS, atuar em unidade básica de saúde (UBS), ter tido contato intradomiciliar com tuberculose (TB), usar álcool, ser fumante e apresentar comorbidades. Para controle de variáveis de confusão e estimativa da medida de efeito (OR), foi empregada a regressão logística. Aplicou-se PT, com leitura após 48-72 horas. As prevalências foram de 57,88% e 37,3%, respectivamente, para 5mm e 10mm. Manteve-se associada à positividade para o ponto de corte de 10mm a condição de trabalhar em UBS com Programa de Controle de Tuberculose (PCT) implementado e já ter tido contato intradomiciliar com TB. Já para o ponto de corte de 5mm, trabalhar em UBS com PCT e implementado. São necessárias ações de conscientização nos municípios e fortalecimento das ações de educação permanente sobre a temática.

Abstract This article aimed to determine the prevalence of latent Mycobacterium tuberculosis infection and associated factors in community health workers (CHW) in Brazil, using two cutoff points for the tuberculin skin test (5mm and 10mm). This was a cross-sectional study with data on gender, age, BCG scar, working in a primary care unit (PCU), having a household contact with tuberculosis (TB), alcohol consumption, previous tuberculin skin test (TST), smoking, time on the job as CHW, and comorbidities. Logistic regression was used to estimate odds ratios (OR) and to control for confounding. TST was applied and read after 48-72 hours. Prevalence rates were 57.88% and 37.3%, respectively, for the 5mm and 10mm TST cutoffs. Variables that remained associated with positive TST using the 10mm cutoff were working in a primary care unit that had implemented a Tuberculosis Control Program (TCP) and history of household contact with TB. Variables associated with the 5mm cutoff were working in a primary care unit with a TCP. Necessary actions at the local level include awareness-raising and strengthening of continuing education.

Objective To evaluate the effect of six-week anaerobic training on the mRNA expression of genes related to proteolysis Ubb (Ubiquitin), E2-14kDa, Trim63 (MuRF1 protein) and Nfkb1 in the skeletal muscle of diabetic rats.Materials and methods Four groups were established: DE (DiabetesExercised), DS (Diabetes Sedentary), CE (Control Exercised) and CS (Control Sedentary). The training consisted of 3 sets of 12 jumps in the liquid mean with load equivalent to 50% of BW for 6 weeks. Euthanasia occurred under ip anesthesia, and blood, adipose tissue and skeletal muscles were collected. Gene expression was quantified by RT–PCR in the gastrocnemius muscle. ANOVA one-way was used for comparison among groups, with post-hoc (Tukey) when necessary, considering p < 0.05.Results We observed reduction in the body weight and adipose tissue in the diabetic groups. The muscle mass was reduced in DS, which could be reversed by training (DE). Although DS and DE have presented similar body weight, the training protocol in DE promoted reduction in the adipose tissue, and increase of muscle mass. Anaerobic training was efficient to reduce glycaemia only in the diabetic animals until 6 hours after the end of training. The Trim63 gene expression was increased in DS; decreased Ubb gene level was observed in trained rats (CE and DE) compared to sedentary (CS and DS), and DE presented the lowest level of E2-14kDa gene expression.Conclusion Six-week anaerobic training promoted muscle mass gain, improved glycemic control, and exerted inhibitory effect on the proteolysis of gastrocnemius muscle of diabetic rats.
