Abstract Diabetic kidney disease (DKD) remains the leading cause of chronic kidney disease (CKD) worldwide. The pathogenesis of DKD is influenced by functional, histopathological, and immune mechanisms, including NLRP3 inflammasome activity and oxidative stress. The sodium-glucose cotransporter 2 inhibitors (SGLT2i) have shown metabolic benefits and the ability to slow the progression of DKD in several clinical studies over the years. Recent studies suggest that the antidiabetic activity also extends to inhibition of the inflammatory response, including modulation of the NLRP3 inflammasome, reduction of pro-inflammatory markers and reduction of oxidative stress. Here we review the efficacy of SGLT2i in the treatment of CKD and discuss the role of the inflammatory response in the development of DKD, including its relationship to the NLRP3 inflammasome and oxidative stress.

Resumo A doença renal do diabetes (DRD) permanece como a principal causa de doença renal crônica (DRC) mundialmente. A patogênese da DRD é influenciada por mecanismos funcionais, histopatológicos e imunológicos, incluindo a atividade do inflamassoma NLRP3 e estresse oxidativo. Os inibidores do cotransportador de sódio-glicose 2 (iSGLT2) demonstraram benefícios metabólicos e a capacidade de retardar a progressão da DRD em diversos estudos clínicos ao longo dos anos. Estudos recentes sugerem que a atividade antidiabética também se estende à inibição da resposta inflamatória, incluindo modulação do inflamassoma NLRP3, redução de marcadores pró-inflamatórios e redução do estresse oxidativo. Aqui, avaliamos a eficácia dos iSGLT2 no tratamento da DRC e discutimos o papel da resposta inflamatória no desenvolvimento da DRD, incluindo sua relação com o inflamassoma NLRP3 e o estresse oxidativo.

Abstract This article describes the political action repertoire mobilized in the construction of public health policy for trans persons in the Manaus, capital city of the state of Amazonas, in northern Brazil. It is based on ethnographic research combining participant observation in the multiple sites where these policies are constructed and interviews with members of two transgender rights organizations in Manaus, between January 2016 and July 2018. Four modes of political action were reconstructed, as ideal types, named after native categories: those of confrontation, others of “articulation”, the ones seeking visibility and others collaboration. Each mode has the local society as public and agents of the municipal and state Judiciary, Legislative and Executive bodies sometimes as adversaries, sometimes as allies.

Abstract Recent studies have suggested that therapies with stem cells and amniotic membrane can modulate the inflammation following an ischemic injury in the heart. This study evaluated the effects of bone-marrow mononuclear cells (BMMC) and acellular human amniotic membrane (AHAM) on cardiac function and NLRP3 complex in a rat model of heart failure.On the 30th day,the echocardiographic showed improvements on ejection fraction and decreased pathological ventricular remodeling on BMMC and AHAM groups.Oxidative stress analysis was similar between the three groups,and the NLRP3 inflammasome activity were not decreased with the therapeutic use of both BMMC and AHAM,in comparison to the control group. bonemarrow bone marrow (BMMC (AHAM NLRP failureOn failure On th daythe day groupsOxidative groups Oxidative groupsand AHAMin group

Abstract Purpose: This article aims to examine the influence of life cycle stages on the corporate decisions of Brazilian firms. Originality/value: The study contributes by presenting a scenario of investment, financing, dividend, and cash decisions, revealing patterns and characteristics of the evolution of Brazilian firms throughout their life cycle stages. For this, we tested an alternative life cycle proxy capable of classifying firms in different stages, even shake-out and decline, not defined by the model of Dickinson (2011), and applied a more robust methodology (GMM-SYS) considering potential endogeneity problems disregarded by previous studies. Design/methodology/approach: The sample consists of 203 traded firms listed on B3 from 2010 to 2018. We collected the data from the Thomson Reuters Eikon database. We estimated the parameters of the models by GMM-SYS (Generalized Method of Moments) to mitigate problems of endogeneity, omitted variables, and heterogeneity. Findings: As our main results, we have that Brazilian firms do not follow a pattern and oscillate between stages and that there is strong evidence of the effect of the life cycle on corporate decisions. In the introduction and growth stages, firms invest more, have more debt, pay fewer dividends, and have greater cash availability. In the mature stage, investments, debts, and the level of cash are lower. In the shake-out stage, no results were significant, requiring further studies to better explore this stage in developing countries, such as Brazil.

Resumo Objetivo: Este artigo tem como objetivo examinar a influência dos estágios do ciclo de vida nas decisões corporativas das empresas brasileiras. Originalidade/valor: O estudo contribui ao apresentar um cenário das decisões de investimento, financiamento, dividendos e caixa, revelando padrões e características da evolução das empresas brasileiras ao longo dos estágios do ciclo de vida. Para isso, testou-se uma proxy alternativa do ciclo de vida capaz de classificar as empresas em diferentes estágios, inclusive turbulência e declínio, não definidos pelo modelo de Dickinson (2011), e aplicou-se uma metodologia mais robusta, levando em conta potenciais problemas de endogeneidade, desconsiderados pelos estudos anteriores. Design/metodologia/abordagem: A amostra é composta por 203 companhias listadas na B3, no período de 2010 a 2018. Os dados foram obtidos na base de dados Thomson Reuters Eikon. A estimação dos parâmetros dos modelos se deu pelo GMM-SYS (Generalized Method of Moments), de modo a atenuar problemas de endogeneidade, variáveis omitidas e heterogeneidade. Resultados: Os resultados sugerem que as empresas brasileiras não seguem um padrão e ficam oscilando entre os estágios, e que existe uma forte evidência do efeito do ciclo de vida nas decisões corporativas. Na introdução e crescimento, as empresas investem mais, têm mais dívidas, pagam menos dividendos e têm maior disponibilidade de caixa. Já na maturidade, os investimentos, as dívidas e o nível de caixa são menores.

Abstract Objective Impulsivity has been robustly linked to various addictions, including behavioral addictions. This systematic review aimed to investigate possible relationships between impulsivity and gaming disorder. Method A total of 1,710 empirical studies, without date or language restrictions, were retrieved from Biblioteca Virtual em Saúde, Cumulative Index to Nursing and Allied Health Literature, PubMed, PsycNET, Scopus, and Web of Science databases. In total, 16 studies met the inclusion criteria and were included for extraction, quantitative analysis, and integrative synthesis. Results Overall, a positive association was observed between gaming disorder and both self-reported measures of impulsivity and behavioral measures of impulsivity. Gaming disorder was associated with the presence of high-risk trends, high sensitivity to rewards, reduced inhibitory control, and low self-control among video game players. Conclusion The present systematic review provides preliminary support for the robust association between impulsivity and gaming disorder. However, given the methodological heterogeneity in assessment instruments and statistical procedures, the identified association should be interpreted cautiously. addictions 1710 1 710 1,71 restrictions Saúde Literature PubMed PsycNET Scopus databases extraction analysis synthesis Overall selfreported self reported highrisk risk trends rewards control selfcontrol players However procedures cautiously 171 71 1,7 17 7 1,

Abstract This study aims to understand the meanings related to sexual health and the delineations that define the experience of accessing health services for lesbian women in Manaus, Brazil. This study followed a qualitative approach, counting on the participation of ten women who self-reported themselves as lesbians. Semi-structured interviews were carried out and their analyses occurred through three thematic axes. The first addressed the representations concerning prevention and sexual practices, highlighting the notion of fidelity in the relationship as a “protective factor”. Difficulties in the use of condoms in relationships between two women were reported. The second discussed heteronormativity and its effects on self-care, reporting the participants’ difficulties in being understood and welcomed by health services. The third addressed the search for one’s own knowledge as a care tactic, highlighting the importance of information and autonomy for health promotion and prevention of Sexually Transmitted Infections (STIs). It can therefore be concluded that there is a need for public policies aimed at promoting the sexual health of lesbian women and the recognition of their specificities by health services.

Abstract Background Unlike cigarette smoking, environmental tobacco smoke (ETS) has not been as well described as an environmental risk for Multiple sclerosis (MS) nor as a risk factor for disease progression. Objective We systematically reviewed the association between ETS and the risk of onset and/or progression of MS. Methods We systematically screened MedLine/PubMed, Science Direct, LILACs, and SciELO searching for publications between January 1st, 2010, and July 5, 2021, with the following keywords: "multiple sclerosis and smoking"; "multiple sclerosis and passive smoking"; "multiple sclerosis and secondhand smoking". Results Fifteen articles were included in this review, which consisted of systematic reviews with meta-analysis (N = 2), systematic reviews (N = 2), and observational studies (N = 11). Both meta-analyses reported an impact of ETS on MS onset among secondhand smokers. One of the systematic reviews selected two observational studies showing the association between ETS and MS development, and one study that did not find a significant association between ETS and the risk of MS development. The other systematic review identified selected eight articles showing a relationship between ETS and MS. Seven observational studies reported higher odds of MS onset when associated with ETS. Four observational studies did not show a relationship between ETS and MS onset or progression. Conclusion Most articles showed a positive association between ETS exposure and the risk of developing MS. On the other hand, an association between ETS and a higher risk for MS progression could not be established. smoking (ETS (MS andor MedLinePubMed MedLine PubMed MedLine/PubMed Direct LILACs 1st st 2010 5 2021 keywords multiple smoking" smoking. . metaanalysis meta analysis N 2, 2 , 2) 11. 11 11) metaanalyses analyses smokers development hand established 201 202 1 20

Abstract This qualitative study, with five participating interlocutors, sought to understand the senses and meanings of parenting among trans men who became pregnant before gender transition. Analysis was conducted in light of social theories of gender. The results demonstrated an experience of parenthood subject to a field of tensions and negotiations, as well as subjective production that oscillated between transgression and accommodation of the cultural perspective of their own experience. The forms of violence found to be practiced reiterated social vulnerabilities, exposed healthcare service weaknesses and produced harmful effects on transgender men who become pregnant before gender transition. study interlocutors transition negotiations vulnerabilities

Abstract The impact of GnRH treatment on the day of TAI in beef cows has received limited investigation, especially concerning its association with estrus expression. Consequently, two experiments were conducted to assess the potential of GnRH treatment on the day of TAI to enhance fertility according to the expression or not of estrus in beef cows. Experiment 1 aimed to determine ovulation rate and luteal function, while Experiment 2 aimed to determine the effect of the two GnRH treatment approaches on pregnancy rate. In Experiment 1, multiparous Brangus suckling cows (n = 17) were submitted to an 8-day TAI protocol. Estrus occurrence was evaluated based on chalk removal on D10 (TAI) and cows were assigned to receive GnRH (25µg lecirelin; im) according to the group: GnRH (n = 7), regardless of estrus expression; or selectGnRH (n = 10), only cows not detected in estrus. Ovulation rate occurring until 77h after IVD removal did not differ (p = 0.17) between GnRH (85.7%; 6/7) and selectGnRH (100%; 10/10). Also, corpus luteum size and serum progesterone concentration were not affected (p>0.05) by treatments. In Experiment 2, crossbred taurine suckled cows (n = 384) were submitted to the same protocol as described in Experiment 1 and were randomly allocated to GnRH or selectGnRH groups. There was no difference in P/AI between groups (selectGnRH = 55.6%; GnRH = 54.3%; p = 0.7) 30 days after TAI. As expected, there was a pronounced effect (p<0.0001) of estrus expression on P/AI (Estrus = 61.5%; No estrus = 33.0%), regardless of group. In summary, ovulation timing and rate and luteal function did not differ between groups. Also, GnRH administration only in cows that do not show estrus is recommended, considering hormone savings and similar conception rate. investigation Consequently n 17 8day 8 D D1 (TAI 25µg µg lecirelin im group 7, 7 , 7) 10, 10 10) h 0.17 017 0 85.7% 857 85 (85.7% 6/7 67 6 100% 100 (100% 10/10. 1010 10/10 . 10/10) Also p>0.05 p005 05 (p>0.05 treatments 384 PAI P AI 55.6% 556 55 54.3% 543 54 3 0.7 07 expected p<0.0001 p00001 0001 (p<0.0001 61.5% 615 61 5 33.0%, 330 33.0% 33 33.0%) summary recommended 0.1 01 85.7 (85.7 6/ (100 101 10/1 p>0.0 p00 (p>0.0 38 55.6 54.3 0. p<0.000 p0000 000 (p<0.000 61.5 33.0 85.

ABSTRACT Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention. sinuses 15 1991 Herein 41yearold yearold 41 year old comorbidities room intervention 1 199 4 19

Abstract Spinal muscular atrophy linked to chromosome 5 (SMA-5q) is an autosomal recessive genetic disease caused by mutations in the SMN1. SMA-5q is characterized by progressive degeneration of the spinal cord and bulbar motor neurons, causing severe motor and respiratory impairment with reduced survival, especially in its more severe clinical forms. In recent years, highly effective disease-modifying therapies have emerged, either acting by regulating the splicing of exon 7 of the SMN2 gene or adding a copy of the SMN1 gene through gene therapy, providing a drastic change in the natural history of the disease. In this way, developing therapeutic guides and expert consensus becomes essential to direct the use of these therapies in clinical practice. This consensus, prepared by Brazilian experts, aimed to review the main available disease-modifying therapies, critically analyze the results of clinical studies, and provide recommendations for their use in clinical practice for patients with SMA-5q. This consensus also addresses aspects related to diagnosis, genetic counseling, and follow-up of patients under drug treatment. Thus, this consensus provides valuable information regarding the current management of SMA-5q, helping therapeutic decisions in clinical practice and promoting additional gains in outcomes.

Resumo Atrofia muscular espinhal ligada ao cromossomo 5 (AME-5q) é uma doença genética de herança autossômica recessiva causada por mutações no gene SMN1. A AME-5q cursa com degeneração progressiva dos motoneurônios medulares e bulbares, acarretando grave comprometimento motor e respiratório com redução da sobrevida, especialmente nas suas formas clínicas mais graves. Nos últimos anos, terapias modificadoras da doença altamente eficazes, ou que atuam regulando o splicing do exon 7 do gene SMN2 ou adicionando uma cópia do gene SMN1 via terapia gênica, têm surgido, proporcionando uma mudança drástica na história natural da doença. Dessa forma, o desenvolvimento de guias terapêuticos e de consensos de especialistas torna-se importante no sentido de direcionar o uso dessas terapias na prática clínica. Este consenso, preparado por especialistas brasileiros, teve como objetivos revisar as principais terapias modificadoras de doença disponíveis, analisar criticamente os resultados dos estudos clínicos dessas terapias e prover recomendações para seu uso na prática clínica para pacientes com AME-5q. Aspectos relativos ao diagnóstico, aconselhamento genético e seguimento dos pacientes em uso das terapias também são abordados nesse consenso. Assim, esse consenso promove valiosas informações a respeito do manejo atual da AME-5q auxiliando decisões terapêuticas na prática clínica e promovendo ganhos adicionais nos desfechos finais.

Abstract Background The SARS-CoV-2 outbreak has led to radical transformation in social, economic, and healthcare systems. This may lead to profound indirect consequences on clinical presentation and management of patients with ST-segment–elevation myocardial infarction. Objectives The objective of this study was to describe the characteristics, management, and outcomes of patients admitted with acute myocardial infarction with ST-segment elevation (STEMI), in two tertiary reference hospitals during the SARS-CoV-2 outbreak and compare them with patients admitted in the previous year. Methods We analyzed data from a multicenter STEMI registry from reference centers in the South Region of Brazil from March 2019 to May 2021. The beginning of the COVID-19 outbreak was considered to be March 2020 and compared to the same period in 2019. Only patients with STEMI submitted to primary percutaneous coronary intervention (PCI) were included in the analysis. Mortality rates were compared with chi-square test. All hypothesis tests had a two-sided significance level of 5%. Results A total of 1169 patients admitted with STEMI were enrolled in our registry, 635 of whom were admitted during the pandemic period. The mean age of our sample was 61.6 (± 12.4) years, and 66.7% of patients were male. Pain-to-door time and door-to-balloon time were longer during the pandemic period. However, there was no difference in mortality rates or major adverse cardiovascular outcomes (MACE). Conclusions We observed a stable incidence of STEMI cases in our registry during the SARS-CoV-2 outbreak with higher pain-to-door time and door-to-balloon time, without any influence on mortality rates however.

ABSTRACT The objective of this study was to estimate the genetic parameters and predict selection of genetic gains and genetic diversity of 12 Andropogon lateralis ecotypes collected in the State of Rio Grande do Sul, Brazil. To estimate genetic parameters and predict selection gains, the REML/BLUP technique was applied. Genetic diversity among the ecotypes was evaluated by two clustering methods (optimization and hierarchical) and principal component (PC) analysis, the latter method also used to discard variables. The genetic parameters studied showed high potential for selection of important agronomic forage traits for livestock production. Results showed that the 12 A. lateralis Nees ecotypes exhibited high genetic variability for the studied forage characters and indicated parental prosperity for crosses within the genetic breeding program. Principal component analysis showed that number of total vegetative tillers, leaf:stem ratio, number of reproductive tillers, and leaf dry matter yield accounted for 80.6% of the observed variation in PC1. These variables are important characteristics for quantifying the dry matter production and nutritional value of forage plants, and they can help to discriminate amongst ecotypes. Ecotypes sourced from the Pelotas, Piratini, Passo Fundo, Bagé, and Montenegro regions showed superior forage production when evaluated by the BLUP methodology. Therefore, this group was identified as the most suitable for selection and crossing purposes. Tocher’s cluster analysis grouped the ecotypes into five divergent groups. Principal component and UPGMA hierarchical methods were also efficient at separating the ecotypes. 1 Sul Brazil REMLBLUP REML applied optimization PC (PC A program tillers leafstem stem ratio 806 80 6 80.6 PC1 plants Pelotas Piratini Fundo Bagé methodology Therefore purposes Tochers Tocher s groups 8 80.

Abstract This study evaluated a new method of adhesive system application on the bond strength between fiber post and root dentin using two adhesive systems. The canals of sixty bovine incisors were prepared and obturated. The roots were divided into six groups (n=10) according to the adhesive system (Clearfil SE - CSE and Single Bond Universal - SBU) and the application strategy (microbrush - MB; rotary brush - RB; and ultrasonic tip - US). The glass fiber posts were cemented with resin cement (RelyX ARC). The roots were sectioned perpendicularly to their long axis, and three slices per root were obtained. Previously to the push-out test, confocal laser scanning microscopy (CLSM) was performed to illustrate the interfacial adaptation of the cement to the root canal walls. Failure patterns were analyzed with 40x magnification. Shapiro-Wilk indicated a normal distribution of the data. The bond strength values were compared using one-way ANOVA and Tukey's tests. Student's T test analyzed the differences between the adhesive systems within each third and protocol. A significance level of 5% was used. CSE with RB showed higher mean bond strength values compared to MB (conventional technique) (P < 0.05). US application resulted in intermediate bond strength values for CSE (P > 0.05). The application of SBU using RB generated higher mean bond strength values compared to MB and US (P < 0.05). Adhesive failures were predominant (65.5%). CSE and SBU application with the new rotary brush improved the bond strength of fiber posts to root dentin compared to the conventional strategy. obturated n=10 n10 n 10 (n=10 Clearfil microbrush US. .

Resumo Este estudo avaliou o efeito de um novo método para aplicação do sistema adesivo na resistência de união entre pino de fibra e dentina radicular usando dois sistemas adesivos. Os canais de sessenta incisivos bovinos foram preparados e obturados. As raízes foram divididas em seis grupos (n=10) de acordo com o sistema adesivo (Clearfil SE - CSE e Single Bond Universal - SBU) e com a estratégia de aplicação (microbrush - MB, escova rotatória - RB e inserto ultrassônico - US). Os pinos de fibra foram cimentados utilizando cimento resinoso (RelyX ARC). As raízes foram seccionadas perpendicularmente ao seu longo eixo e três fatias foram obtidas. Previamente ao teste de push-out, foi realizada microscopia de varredura confocal a laser para ilustrar a adaptação interfacial do cimento às paredes do canal radicular. Os padrões de falha foram analisados com magnificação de 40x. O teste de Shapiro-Wilk indicou distribuição normal dos dados. Os valores de resistência de união foram comparados usando o teste ANOVA de uma via e post hoc de Tukey. As diferenças entre os sistemas adesivos em cada terço e de acordo com cada protocolo foram analisadas pelo teste T de Student. O nível de significância foi de 5%. CSE aplicado com RB apresentou maiores valores médios de resistência de união do que quando aplicado com MB (técnica convencional) (P<0,05). Aplicação com US apresentou valores intermediários de resistência de união para o CSE (P>0,05). A aplicação do SBU utilizando RB gerou maiores valores médios de resistência de união comparados com MB e US (P<0,05). Falhas adesivas foram predominantes (65,5%). A aplicação do CSE e SBU com a nova escova rotatória melhorou a resistência de união dos pinos de fibra à dentina radicular comparados com a estratégia convencional. obturados n=10 n10 n 10 (n=10 Clearfil microbrush US. .

Abstract Pain is the most common complaint reported to orthopedists in the outpatient clinic, emergency room, or booth. Numerous publications report the inadequate management of both acute and chronic pain by health professionals. This updated article aims to provide information about musculoskeletal pain, its classification, evaluation, diagnosis, and the multimodal therapeutic approach for each case. For acute pain, adequate control allows for earlier rehabilitation to work and reduces the rates of pain chronification. For chronic pain, the goal is to reduce its intensity and improve the quality of life. Currently, some procedures are increasingly used and aided by imaging tests for diagnostic and therapeutic purposes. clinic room booth professionals classification evaluation diagnosis case chronification life Currently purposes

Resumo A dor é a queixa mais comum recebida pelo ortopedista no ambulatório e/ou emergência. Inúmeras publicações relatam o manejo inadequado tanto da dor aguda quanto da dor crônica pelos profissionais da saúde. O objetivo desse artigo de atualização é trazer informações sobre a dor musculoesquelética, sua classificação, avaliação, diagnóstico e abordagem terapêutica multimodal para cada situação. Desta maneira, nas dores agudas seu controle adequado possibilita um trabalho de reabilitação mais precoce, bem como diminui os índices de cronificação da dor. Nas dores crônicas sua abordagem além da diminuição de sua intensidade, visa também melhorar a qualidade de vida. Atualmente alguns procedimentos estão sendo cada vez mais utilizados com auxílio de aparato de imagem com objetivo diagnóstico e terapêutico. eou ou emergência saúde musculoesquelética classificação avaliação situação maneira precoce intensidade vida terapêutico
