ABSTRACT OBJECTIVES To estimate the relative risk (RR) of death associated with obesity, the attributable fraction in the exposed/with obesity (AFo), and the hospitalized population attributable risk (hospitalized PAR) associated with obesity of death among all adults and among Black and non-Black adults hospitalized for severe COVID-19 in the state of Rio Grande do Sul, Brazil. METHODS This retrospective cohort study of prognostic factors analyzed all cases of adults hospitalized for severe COVID-19 in the state of Rio Grande do Sul, Brazil. The occurrence of obesity was measured using secondary data from hospital teams’ surveillance records. The outcome assessed was hospital deaths caused by severe COVID-19. Poisson regression was used to estimate RRs and 95% confidence intervals (95%CI). RESULTS The study sample consisted of 100,099 patients hospitalized for severe COVID-19, most of whom were White (84.7%) and male (54.7%). The effect of obesity was strongly modified by age, being higher in younger age groups. For the 18–39-year-old age group, RR = 2.54 (95%CI: 2.33–2.77), and in individuals 70 years and above, RR = 1.09 (95%CI: 1.05–1.13). For the 18–39-year-old age range, AFo = 60.6% and AFo = 42.5% in individuals 40–59 years old. For all hospitalizations, Hospitalized PAR measuring obesity for individuals 18–39 years old was 25.3%, while in the 40–59-year-old range, the hospitalized PAR = 11.2%. The hospitalized PAR was 31.7% in the Black population aged 18–39 years and 24.8% in non-Blacks. The hospitalized PAR was also larger in Blacks aged 40-59 years. CONCLUSIONS Obesity largely impacted in-hospital case-fatality rates among young adults and Black people contaminated by COVID-19. These data highlight the extent of the risk concerning obesity, a highly prevalent chronic condition.

RESUMO Objetivo: Tendo em vista que o sistema visual representa uma via de contaminação para o novo Corona vírus, a The Global Alliance of Eye Bank Association (GAEBA) divulgou um guideline preconizando a prevenção de transmissão do vírus entre o doadores de tecido ocular e o pacientes receptores, o que resultou em uma diminuição no número de ceratoplastias e aumento de filas de espera para transplantes de córnea (TC) em todo o mundo. Nesse sentido, o presente trabalho tem por objetivo analisar a situação do transplante de córnea (TC) no estado de Alagoas durante o primeiro ano de pandemia da COVID-19. Métodos: Trata-se de um estudo analítico, transversal, observacional utilizando dados provenientes de 3 fontes diferentes: Banco de Tecido Ocular Humano de Alagoas (BTO-AL), Registro Brasileiro de Transplantes (RBT) e Agência Nacional de Vigilância Sanitária (ANVISA). Resultados: Durante os últimos seis anos, foram realizados 284 TCs em Alagoas, segundo dados do Banco de Transplante de Olhos do estado (BTO), já segundo a Registro Brasileiro de Transplantes (RBT) foram realizados 451 TCs. A porcentagem de córneas não oriundas do BTO de Alagoas se mostrou crescente até 2019, porém decresceu em 2020, e no primeiro ano de pandemia , apenas 11,66% da necessidade anual estimada foi atendida, sendo o período com menor número de TCs realizados entre os seis anos analisados na pesquisa. Conclusão: O estudo demonstra o declínio na doação e realização de transplantes de córnea durante o primeiro ano da pandemia da COVID-19 em Alagoas.

ABSTRACT Objective: Considering the visual system is one source of contamination for the new coronavirus, The Global Alliance of Eye Bank Association (GAEBA) released a guideline recommending prevention of virus transmission between eye tissue donors and recipients, which resulted in a reduction of keratoplasties and increase in the waiting lists for corneal transplants worldwide. Hence, this work aims to analyze the situation of corneal transplantation in the state of Alagoas, during the first year of COVID-19 pandemic. Methods: This is an analytical, cross-sectional, observational study using data from 3 different sources: Human Eye Tissue Bank of Alagoas (BTO-AL), Brazilian Transplant Registry (RBT) and National Health Surveillance Agency (ANVISA). Results: During the past six years, 284 corneal transplants were performed in Alagoas, according to data from the Eye Transplant Bank (BTO) of the state, whereas according to the Brazilian Transplant Registry (RBT) 451 corneal transplants were performed. The percentage of corneas not coming from the BTO of Alagoas increased until 2019 but dropped in 2020. In the first year of the pandemic, only 11.66% of estimated annual need was met, and this period had the lowest number of corneal transplants performed out of the six years analyzed in the research. Conclusion: The study demonstrated the decline in donation and performance of corneal transplants during the first year of the COVID-19 pandemic in Alagoas.

Abstract Rheumatoid arthritis (RA) is a chronic and autoimmune systemic inflammatory disease that can cause irreversible joint deformities, with increased morbidity and mortality and a significant impact on the quality of life of the affected individual. The main objective of RA treatment is to achieve sustained clinical remission or low disease activity. However, up to 40% of patients do not respond to available treatments, including bDMARDs. New therapeutic targets for RA are emerging, such as Janus kinases (JAKs). These are essential for intracellular signaling (via JAK-STAT) in response to many cytokines involved in RA immunopathogenesis. JAK inhibitors (JAKi) have established themselves as a highly effective treatment, gaining increasing space in the therapeutic arsenal for the treatment of RA. The current recommendations aim to present a review of the main aspects related to the efficacy and safety of JAKis in RA patients, and to update the recommendations and treatment algorithm proposed by the Brazilian Society of Rheumatology in 2017.

RESUMO Objetivou-se avaliar no presente trabalho a digestibilidade in vitro de nutrientes de diferentes dietas com a adição de quitosana (Q), líquido da casca da castanha de caju (LCC) e a associação entre Q e LCC. Os tratamentos utilizados foram constituídos de 4 dietas (relação volumoso:concentrado, 100:0, 50:50, 40:60 e 20:80) associadas com 4 aditivos (controle, quitosana, LCC e a associação entre ambos Q+LCCt), totalizando 16 tratamentos,distribuídas em delineamento em blocos ao acaso em esquema fatorial 4x4. As dosagens utilizadas foram: Controle (sem adição de aditivos), LCC (600mg/Kg de MS), Quitosana (900mg/Kg de MS), e o LCCQ (600mg/Kg de MS de LCC + 900mg/Kg de MS de quitosana). No laboratório foram avaliados a DIVMS, DIVFDN, DIVPB, pH e NAR (nitrogênio amoniacal ruminal). Para as análises de pH e NAR, foram coletadas amostras nas horas 0, 2, 4, 6 e 8 após a incubação. Os resultados encontrados mostraram maior digestibilidade de MS, FDN e PB para dietas que receberam quitosana e líquido da casca da castanha de caju de forma isolada e maiores valores de pH e NAR nas dietas que receberam os dois aditivos associados. Conclui-se que a associação dos aditivos traz melhores resultados para a nutrição animal e eleva a produtividade dos ruminantes.

ABSTRACT This study evaluated the in vitro digestibility of nutrients from different diets added with chitosan (Q), technic cashew nut shell liquid (LCC) and the association of Q and LCC. The treatments used consisted of 4 diets (forage: concentrate ratio of 100: 0, 50:50, 40:60 and 20:80) associated with 4 additives (control, chitosan, LCC and the association of Q + LCC), totaling 16 treatments, in a 4x4 factorial randomized block design. The dosages used were: Control (without additives), LCC (600mg/kg DM), Chitosan (900mg/kg DM), and LCCQ (600mg/kg LCC DM + 900mg/kg Chitosan DM). In the laboratory, samples were analyzed for IVDMD, IVNDFD, IVCPD, pH and RAN (ruminal ammonia nitrogen). For pH and RAN analyses, samples were taken at 0, 2, 4, 6 and 8 hours after incubation. The results showed higher digestibility of DM, NDF and CP for diets with chitosan and technic cashew nut shell liquid alone and higher pH and RAN values in the diets containing the two additives. The association of additives brings better results for animal nutrition and increases ruminant productivity.

Abstract Background: In Brazil, we are facing an alarming epidemic scenario of Yellow fever (YF), which is reaching the most populous areas of the country in unvaccinated people. Vaccination is the only effective tool to prevent YF. In special situations, such as patients with chronic immune-mediated inflammatory diseases (CIMID), undergoing immunosuppressive therapy, as a higher risk of severe adverse events may occur, assessment of the risk-benefit ratio of the yellow fever vaccine (YFV) should be performed on an individual level. Main body of the abstract: Faced with the scarcity of specific orientation on YFV for this special group of patients, the Brazilian Rheumatology Society (BRS) endorsed a project aiming the development of individualized YFV recommendations for patients with CIMID, guided by questions addressed by both medical professionals and patients, followed an internationally validated methodology (GIN-McMaster Guideline Development). Firstly, a systematic review was carried out and an expert panel formed to take part of the decision process, comprising BRS clinical practitioners, as well as individuals from the Brazilian Dermatology Society (BDS), Brazilian Inflammatory Bowel Diseases Study Group (GEDIIB), and specialists on infectious diseases and vaccination (from Tropical Medicine, Infectious Diseases and Immunizations National Societies); in addition, two representatives of patient groups were included as members of the panel. When the quality of the evidence was low or there was a lack of evidence to determine the recommendations, the decisions were based on the expert opinion panel and a Delphi approach was performed. A recommendation was accepted upon achieving ≥80% agreement among the panel, including the patient representatives. As a result, eight recommendations were developed regarding the safety of YFV in patients with CIMID, considering the immunosuppression degree conferred by the treatment used. It was not possible to establish recommendations on the effectiveness of YFV in these patients as there is no consistent evidence to support these recommendations. Conclusion: This paper approaches a real need, assessed by clinicians and patient care groups, to address specific questions on the management of YFV in patients with CIMID living or traveling to YF endemic areas, involving specialists from many areas together with patients, and might have global applicability, contributing to and supporting vaccination practices. We recommended a shared decision-making approach on taking or not the YFV.

Resumo O presente artigo identifica as Regiões de Saúde do Rio Grande do Sul (RS) prioritárias com vistas a implementar ações para o fortalecimento da Vigilância em Saúde. Estudo descritivo com dados da série histórica de 11 (onze) indicadores de Vigilância em Saúde do Caderno de Diretrizes, Objetivos, Metas e Indicadores 2016, do Ministério da Saúde pactuados pela Comissão Intergestores Bipartite/RS. Os indicadores selecionados são sintetizados para produzir um Indicador Composto de Avaliação da Vigilância em Saúde (ICAVES) para cada uma das 30 Regiões de Saúde do estado, criando valores que variam de 0 (pior) a 1 (melhor), tendo como método de cálculo o utilizado para a construção do Índice de Desenvolvimento Humano (IDH). Os menores índices do indicador composto estão nas Regiões de Saúde: 20-Rota da Produção e 19-Região do Botucaraí. As Regiões de Saúde 20 e 19 são prioritárias para o fortalecimento das ações de âmbito coletivo da Vigilância em Saúde e o gerenciamento de riscos e agravos à saúde considerando a equidade horizontal como diretriz do Sistema Único de Saúde.

Abstract This paper aimed to identify the priority Health Regions of Rio Grande do Sul (RS) to implement Health Surveillance strengthening actions. This is a descriptive study with data from time series of 11 (eleven) Health Surveillance indicators of the Ministry of Health’s 2016 Guidelines, Objectives, Targets and Indicators Journal agreed by the Bipartite Interagency Committee/RS. The selected indicators are synthesized to produce a Composite Health Surveillance Assessment Indicator (ICAVES) for each of the 30 Health Regions of the state, creating values ranging from zero (worst) to 1 (best), using the Human Development Index (HDI) construction calculation method. The lowest rates of the composite indicator are found in the Health Regions “20-Rota da Produção” and “19-Região do Botucaraí”. These two Health Regions are priorities for the strengthening of collective Health Surveillance actions and the management of health risks and diseases, considering horizontal equity as guideline of the Unified Health System.

Abstract Purpose: To evaluate the effects of tramadol hydrochloride associated to remote ischemic perconditioning on oxidative stress. Methods: Twenty five male rats (Wistar) underwent right nephrectomy and were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minutes of renal ischemia; Remote ischemic perconditioning group (Per) with three cycles of 10 minutes of I/R performed during kidney ischemia; Tramadol group (T) treated with tramadol hydrochloride (40mg/kg); remote ischemic perconditioning + Tramadol group (Per+T) with both treatments. Oxidative stress was assessed after 24 hours of reperfusion. Results: Statistical differences were observed in MDA levels between I/R group with all groups (p<0.01), in addition there was difference between Tramadol with Sham, Per and Per+T groups (p<0.05), both in plasma and renal tissue. Conclusion: Remote ischemic perconditioning was more effective reducing renal ischemia-reperfusion injury than administration of tramadol or association of both treatments.

O tratamento das doenças reumáticas autoimunes sofreu uma progressiva melhora ao longo da última metade do século passado, que foi expandida com a contribuição das terapias biológicas ou imunobiológicos. No entanto, há que se atentar para as possibilidades de efeitos indesejáveis advindos da utilização dessa classe de medicações. A Sociedade Brasileira de Reumatologia (SBR) elaborou um documento, baseado em ampla revisão da literatura, sobre os aspectos relativos à segurança dessa classe de fármacos, mais especificamente no que diz respeito ao tratamento da artrite reumatoide (AR) e das espondiloartrites. Os temas selecionados pelos especialistas participantes, sobre os quais foram estabelecidas considerações quanto à segurança do uso de drogas biológicas, foram: ocorrência de infecções (bacterianas, virais, tuberculose), reações infusionais, reações hematológicas, neurológicas, gastrointestinais, cardiovasculares, ocorrências neoplásicas (neoplasias sólidas e da linhagem hematológica), imunogenicidade, outras ocorrências e reposta vacinal. Optou-se, por motivos didáticos, por se fazer um resumo da avaliação de segurança, de acordo com os tópicos anteriores, por classe de drogas/mecanismo de ação (antagonistas do fator de necrose tumoral, bloqueador da co-estimulação do linfócito T, depletor de linfócito B e bloqueador do receptor de interleucina-6). Em separado, foram tecidas considerações gerais sobre segurança do uso de biológicos na gravidez e na lactação. Esta revisão procura oferecer uma atualização ampla e equilibrada das experiências clínica e experimental acumuladas nas últimas duas décadas de uso de medicamentos imunobiológicos para o tratamento da AR e espondiloartrites.

The treatment of autoimmune rheumatic diseases has gradually improved over the last half century, which has been expanded with the contribution of biological therapies or immunobiopharmaceuticals. However, we must be alert to the possibilities of undesirable effects from the use of this class of medications. The Brazilian Society of Rheumatology (Sociedade Brasileira de Reumatologia) produced a document based on a comprehensive literature review on the safety aspects of this class of drugs, specifically with regard to the treatment of rheumatoid arthritis and spondyloarthritides. The themes selected by the participating experts, on which considerations have been established as the safe use of biological drugs, were: occurrence of infections (bacterial, viral, tuberculosis), infusion reactions, hematological, neurological, gastrointestinal and cardiovascular reactions, neoplastic events (solid tumors and hematologic neoplasms), immunogenicity, other occurrences and vaccine response. For didactic reasons, we opted by elaborating a summary of safety assessment in accordance with the previous themes, by drug class/mechanism of action (tumor necrosis factor antagonists, T-cell co-stimulation blockers, B-cell depletors and interleukin-6 receptor blockers). Separately, general considerations on safety in the use of biologicals in pregnancy and lactation were proposed. This review seeks to provide a broad and balanced update of that clinical and experimental experience pooled over the last two decades of use of immunobiological drugs for RA and spondyloarthritides treatment.

INTRODUÇÃO: A sepse é uma síndrome complexa causada pela resposta inflamatória sistêmica descontrolada. As citocinas inflamatórias representam papel central na patogênese do choque séptico. Têm sido testadas estratégias terapêuticas a fim de modular a geração ou a função excessiva de mediadores na sepse. OBJETIVO: O objetivo deste estudo foi investigar o efeito terapêutico da N-acetilcisteína (NAC) e sua associação com a frutose-1,6-bisfosfato (FBP) sobre a proliferação de linfócitos T e a geração de interleucina-1β (IL-1β) e proteína quimiotática de monócitos 1 (MCP-1) em cultura celular. MATERIAL E MÉTODOS: Foram isoladas células mononucleares de sangue periférico de indivíduos saudáveis. Os linfócitos T foram estimulados por 96 horas com fitohemaglutinina e submetidos a diferentes concentrações de NAC ou NAC associada à FBP (1,25 mM). RESULTADOS: O tratamento com NAC (10 e 15 mM) ou NAC (15 mM) associado à FBP reduziu a proliferação celular. Os níveis de IL-1β aumentaram com a presença de NAC (15 mM) e NAC + FBP. A concentração de MCP-1 mostrou-se reduzida apenas no grupo tratado com NAC associada à FBP. CONCLUSÃO: Os resultados sugerem que tanto a NAC quanto a NAC associada à FBP são capazes de inibir a proliferação celular, atuando como potentes agentes imunomoduladores, sugerindo seu uso em doenças inflamatórias.

INTRODUCTION: Sepsis is a complex syndrome caused by an uncontrolled systemic inflammatory response. Inflammatory cytokines play a pivotal role in septic shock pathogenesis. Therapeutic strategies have been tested in order to modulate the excessive generation or function of sepsis mediators. OBJECTIVE: The objective of the present study was to investigate the therapeutic effect of N-acetylcysteine (NAC) and its association with fructose-1,6-bisphosphate (FBP) on T-lymphocytes proliferation, interleukin-1β (IL-1β) and monocyte chemotactic protein-1 (MCP-1) levels. MATERIAL AND METHODS: Peripheral blood mononuclear cell samples were isolated from healthy individuals. T-lymphocytes were stimulated with phytohemagglutinin for 96 hours and submitted to different concentrations of NAC or NAC associated with FBP. RESULTS: NAC (10 and 15 mM) and NAC (15 mM) associated with FBP reduced T-lymphocytes proliferation. IL-1β levels rose in the presence of both NAC (15 mM) and NAC with FBP (1.25 mM). MCP-1 levels were reduced only by NAC (15 mM) associated with FBP (1.25 mM). CONCLUSION: The results suggest that both NAC itself and NAC associated with FBP inhibit cellular proliferation, acting as potent immunomodulatory agents, which corroborates its use in the treatment of inflammatory diseases.

Após uma injúria corneana, é fundamental a eliminação dos miofibroblastos a fim de garantir sua transparência. Os miofibroblastos corneanos apresentam um receptor para o fator ativador de plaquetas em sua superfície. O concentrado de plaquetas é uma das mais ricas fontes de fatores de crescimento essenciais, causando redução do sangramento, da inflamação, da escarificação, do tempo de cicatrização, acelerando assim o fechamento das úlceras.Relatamos um caso de úlcera trófica corneana não responsiva aos tratamentos convencionais e que apresentou melhora clínica significativa com colírio de concentrado de plaquetas autólogo.

In order to assure corneal transparency after injury the effective removal of myofibroblasts is fundamental. The corneal myofibroblasts display platelet activator factor receptor on its surface. The platelet concentrate is one of the richest sources of essential growth factors, reducing bleeding, inflammation, scaring time, thus speeding up the closing of the ulcers. We report a case which provides evidence of clinical improvement with concentrate platelet eyedrops on a non responsive trophic corneal disease.
