Abstract Objective: The use of parenteral nutrition (PN) formulations that do not contain iodine can contribute to the deficiency of this mineral, potentially leading to hypothyroidism and, ultimately, neurocognitive impairments. This study aimed to evaluate TSH alterations in newborns receiving PN. Methods: Retrospective study of neonatal intensive care unit patients receiving PN for > 15 days. Nutritional, anthropometric, and biochemical variables (TSH, T4, CRP) were analyzed. Hypothyroidism was defined by TSH > 10 mU/L. Results: Two hundred newborns were evaluated [156 (78%) preterm, 31±5 weeks of gestational age, 112 (56%) with very or extremely low birth weight]. The median (IQR) hospital stay was 68 (42-110) days, PN duration was 31 (21-47) days, and 188 (94%) patients also received enteral nutrition. Overall, 143 (71.5%) newborns underwent at least one TSH measurement. The prevalence of hypothyroidism was 10.5%. The Median PN duration in this group was 51 (34-109) days. Among those with hypothyroidism, 10 received Lugol’s solution and six levothyroxine. Thirteen patients received prophylactic Lugol’s solution with a median PN duration of 63 (48-197) days. TSH levels correlated positively with PN duration (r = 0.19, p = .02). Conclusions: The present data suggest that changes in TSH and T4 levels are present in neonates receiving PN for > 15 days, suggesting this population may be at risk for developing hypothyroid-ism. Therefore, the authors suggest that TSH and T4 measurements should be included as routine in neonatal patients receiving PN for > 15 days if PN formulations are not supplemented with iodine, and that iodine supplementation be provided as necessary.

Abstract: En | Text: En | PDF: En

ABSTRACT Dogs are considered to be the main domestic reservoir associated with the transmission of Leishmania (L.) infantum chagasi to humans in endemic areas of visceral leishmaniasis in America. However, little is known about the role of canines as a source of infection in endemic areas of nonulcerated cutaneous leishmaniasis (NUCL). Therefore, the objective of the present study was to investigate the role of dogs as a possible reservoir of the parasite in Southern Honduras. Dogs (n = 107) living with individuals affected by NUCL were clinically examined and biological material was collected for parasitological and immunological diagnosis. Most animals showed a healthy appearance and a few presented slight weight loss (64%), alopecia (7%), onychogryphosis (5%) and skin lesions (1%). The overall seroprevalence of Leishmania infection based on the DDP ® quick test and/or in-house ELISA serological test was 41%. The presence of the parasite’s DNA was confirmed in 94% of the dogs; however, the average parasite load in the buffy coat was low at 6.09 parasites/µL, ranging between 0.221 and 50.2. The skin of seropositive dogs examined by histopathology using paraffin sections stained by hematoxylin and immunohistochemistry did not show cutaneous lesions or parasite amastigotes. Based on the absence of parasites in the skin and the low parasite load detected in the buffy coat, it seems that the dog does not represent a good source of infection for the vector in the endemic area of NUCL transmission in Southern Honduras. Other domestic and/or wild animals should be investigated.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Abstract: En | Text: En | PDF: En

ABSTRACT COVID-19 is commonly associated with high serum levels of pro-inflammatory cytokines, and the post-infection status can disturb self-tolerance and trigger autoimmune responses. We are reporting a 45-year-old male who was admitted with fatigue, jaundice, elevated liver enzymes (with cholestatic pattern), and acute kidney injury two weeks after recovering from a mild SARS-CoV-2 infection. Serologies for viral hepatitis and anti-mitochondrial antibody were negative, while anti-nuclear and anti-smooth muscle antibodies were positive. There were no signs of chronic liver disease, and a magnetic resonance cholangiography showed no dilatation of biliary ducts. Histologic evaluation of the liver evidenced numerous foci of lobular necrosis without ductopenia or portal biliary reaction. Considering the autoantibody profile and histologic changes, the medical team started oral prednisone, but there was a suboptimal biochemical response in the outpatient follow-up. Two months later, a second liver biopsy was performed and revealed non-suppurative destructive chronic cholangitis, extensive areas of confluent necrosis with hepatocytes regenerating into pseudorosettes, and numerous plasma cells. According to the Paris Criteria, the patient was then diagnosed with an autoimmune hepatitis-primary biliary cholangitis overlap syndrome (AIH-PBC-OS). After adding azathioprine and ursodeoxycholic acid to the treatment, there was a satisfactory response. This is the second worldwide report of an AIH-PBC-OS triggered by COVID-19, but the first case with a negative anti-mitochondrial antibody. In this setting, histologic evaluation of the liver by an experienced pathologist is a hallmark of achieving the diagnosis and correctly treat the patient.

Abstract Objectives To evaluate neonatal autopsy rates at a tertiary hospital in southern Brazil ascertain the level of agreement between premortem and postmortem diagnosis. Methods The authors reviewed all neonatal autopsies performed over a 10-year period and described the percentage of neonates who died and underwent autopsy. The authors tested for agreement between autopsy findings and the cause of death as defined by the neonatologist. Agreement between clinical diagnosis and autopsy findings was classified using the modified Goldman criteria. Additional findings at autopsy were grouped by organ system. Linear regression and multiple comparisons were used for statistical analyses. Results During the study period, 382 neonates died at the Neonatal Intensive Care Unit (NICU). Consent to perform an autopsy was obtained for 73 (19.1%). The complete agreement between autopsy findings and the neonatologist's premortem diagnosis was found in 48 patients (65.8%). Additional findings were obtained at autopsy in 25 cases (34.2%). In 5 cases (6.9%), the autopsy findings contributed to subsequent genetic counseling. Seven autopsies (9.6%) revealed a diagnosis that would have changed patient management if established premortem. The autopsy rate increased by an average of 1.87% each year. Conclusion Despite a high level of agreement between clinical diagnosis and pathological findings, autopsies provided relevant data regarding the cause of death, providing additional clinical information to neonatologists and allowing genetic counseling of family members.

RESUMO Antecedentes: Critérios clínicos e de imagem são necessários para caracterizar atividade e progressão em esclerose múltipla (EM). Os parâmetros para a atividade são bem definidos, o que não ocorre com a progressão. O objetivo ideal para tratamento em longo prazo inclui ausência de sinais clínicos e de imagem, assim como inexistência de atrofia cerebral. Objetivos: Estudo comparativo de aspectos clínicos e correlatos de imagem, com foco em volumetria cerebral. Métodos: Foram avaliados 174 pacientes consecutivos com o diagnóstico de EM surto-remissiva (McDonald 2001), com foco em dados de atividade e progressão. A avaliação clínica anual (taxa de surtos e escala expandida do estado de incapacidade - EDSS) e dados de imagem, assim como a evolução anualizada do Índice de Corpo Caloso (CCI), foram comparados. Resultados: Da amostra inicial de 174 pacientes, 148 foram considerados “clinicamente estáveis” com base na EDSS. Todavia, 33 (22,2%) pacientes desse grupo mostraram redução volumétrica anualizada no índice de corpo caloso acima de 0,5%, nível de corte para definir a atrofia cerebral significativa. Conclusões: Entre pacientes de EM surto-remissiva aparentemente estáveis, cerca de 1/5 apresentou sinais de atrofia cerebral significativa em sete anos de seguimento. Consideramos razoável sugerir que sequências de volumetria deveriam ser incluídas nos protocolos de seguimento, fornecendo informação quanto ao real estado da resposta ao tratamento.

ABSTRACT Background: Clinical and imaging are required to characterize activity and progression in MS. The parameters for activity are well defined but not those for progression. The ideal aim for long-term treatment is that neither clinical nor imaging signs of disease should be present, and also no brain atrophy. Objectives: To conduct a comparative clinical-imaging study focusing on MRI brain volumetry. Methods: 174 consecutive relapsing-remitting MS patients (McDonald 2001) were studied, focusing on activity and progression. Annual clinical evaluations (relapse rate and EDSS) and MRI data, along with the annualized evolution of the corpus callosum index (CCI), were compared. Results: Out of 174 patients, 148 were considered clinically “stable” based on EDSS. However, 33 (22.2%) out of this group showed annualized reductions in CCI of more than 0.5%, which was the cutoff for defining significant brain atrophy. Conclusions: Among apparently “stable” relapsing-remitting MS patients, 1/5 showed significant brain atrophy over a follow-up period of at least 7 years. We consider it reasonable to suggest that MRI volume sequences should be included in follow-up protocols, so as to provide information on the real treatment response status.

RESUMO Contexto A suplementação com probióticos, prebióticos e simbióticos mostrou efeitos positivos sobre marcadores clínicos e fatores de risco para doença hepática gordurosa não alcoólica (DHGNA). Objetivo Avaliar o efeito da suplementação com probióticos, prebióticos ou simbióticos na microbiota intestinal em pacientes com DHGNA. Métodos Dois pesquisadores realizaram buscas independentes de artigos nas bases de dados Medline, via PubMed, Web of Science, Embase, Scopus, Lilacs, Biblioteca Central Cochrane, Clinical Trials.gov e na plataforma Ovid para busca de literatura cinza. Os títulos e resumos foram lidos para excluir artigos irrelevantes. Em seguida, os artigos selecionados foram lidos na íntegra e avaliados de acordo com os critérios de elegibilidade. O risco de viés foi avaliado de acordo com a Cochrane. Resultados Um total de 3.423 artigos foram identificado por meio de busca nas bases de dados eletrônicas; 1.560 deles eram duplicados e foram excluídos; 1.825 artigos foram excluídos após a leitura do título e do resumo. Um total de 39 artigos foram selecionado para leitura, porém apenas quatro artigos atenderam aos critérios de elegibilidade para inclusão nesta revisão sistemática. Três dos estudos incluídos que utilizaram suplementação de prebióticos ou simbióticos mostraram que após a intervenção ocorreram mudanças no padrão da microbiota intestinal. Apenas em um estudo tais mudanças não foram observadas. Um elevado risco de viés foi observado na maioria das avaliações. Conclusão Embora haja uma possível alteração na microbiota intestinal de indivíduos com DHGNA após a suplementação com simbióticos ou prebióticos, uma indicação clínica como parte do tratamento da DHGNA ainda não é possível.

ABSTRACT Background Supplementation with probiotics, prebiotics and symbiotics has shown positive effects on clinical markers and risk factors for non-alcoholic fatty liver disease (NAFLD). Objective To evaluate the effect of supplementation with probiotic, prebiotic or symbiotic on intestinal microbiota in NAFLD patients. Methods Two investigators conducted independently search for articles in the Medline databases, via PubMed, Web of Science, Embase, Scopus, Lilacs, Central Cochrane Library, Clinical Trials.gov and on the Ovid platform for the gray literature search. Results A total of 3,423 papers were identified by searching the electronic databases; 1,560 of them were duplicate and they were excluded; 1,825 articles were excluded after reading the title and abstract. A total of 39 articles were select to reading, however only four articles met the eligibility criteria to include in this systematic review. Three of the included studies that used prebiotic or symbiotic supplementation showed that after the intervention there were changes in the intestinal microbiota pattern. Only in one study such changes were not observed. A high risk of bias was observed in most assessments. Conclusion Although there is a possible change in the gut microbiota of individuals with NAFLD after supplementation with symbiotics or prebiotics, a clinical indication as part of NAFLD treatment is not yet possible.

Resumo Fundamento A ação do peptídeo natriurético atrial (ANP) na natriurese, diurese e vasodilatação, resistência à insulina, fígado, rim e tecido adiposo pode contribuir para o desenvolvimento metabólico e cardiovascular saudável. Embora o nível circulante de ANP seja reduzido em pacientes com obesidade, sua resposta à perda de peso ainda é pouco explorada em populações pediátricas. Objetivo Avaliar os efeitos das variações do ANP em resposta à intervenção interdisciplinar para perda de peso na Síndrome Metabólica (SMet) e nos riscos cardiometabólicos em adolescentes com obesidade. Métodos 73 adolescentes com obesidade participaram de uma terapia interdisciplinar para perda de peso de 20 semanas, incluindo uma abordagem clínica, nutricional, psicológica e de exercícios físicos. A composição corporal, análises bioquímicas e pressão sanguínea foram avaliadas. A SMet foi classificada de acordo com a Federação Internacional de Diabetes (IDF) (2007). Após o tratamento, os voluntários foram divididos de acordo com os níveis de plasma do ANP aumento (n=31) ou ANP redução (n=19). Resultados Ambos os grupos apresentaram redução significativa de peso corporal, índice de massa corporal (IMC) e circunferências de cintura, pescoço e quadril (CC, CP e CQ, respectivamente), e aumento da massa livre de gordura (MLG). É interessante observar que houve uma redução significativa na gordura corporal, na razão de TG/HDL-c e na prevalência de SMet (de 23% para 6%) somente no grupo com ANP aumento. Conclusão Este estudo sugere que o aumento nos níveis séricos de ANP após a terapia para perda de peso pode estar associado a melhorias nos riscos cardiometabólicos e na prevalência reduzida de SMet em adolescentes com obesidade.

Abstract Background The action of atrial natriuretic peptide (ANP) on natriuresis, diuresis and vasodilatation, insulin resistance, liver, kidney, and adipose tissue may contribute to the healthy metabolic and cardiovascular development. Even though the circulating level of ANP is reduced in patients with obesity, its response to weight loss remains poorly explored in pediatric populations. Objective To evaluate the effects of ANP variations in response to interdisciplinary weight loss intervention on metabolic syndrome (MetS) and cardiometabolic risks in adolescents with obesity. Methods 73 adolescents with obesity attended a 20-week clinical interdisciplinary weight loss therapy including clinical, nutritional, psychological and exercise training approach. Body composition, biochemical analyses and blood pressure were evaluated. MetS was classified according to the International Diabetes Federation (IDF) (2007). After the treatment, volunteers were divided according to Increasing (n=31) or Decreasing (n=19) ANP plasma levels. Results Both groups present significant reduction of body weight, Body Mass Index (BMI), waist, neck and hip circumferences (WC, NC and HC, respectively) and increasing fat-free mass (FFM). Interestingly, a significant reduction in body fat, TG/HDL-c ratio and MetS prevalence (from 23% to 6%) was observed in the Increased ANP group only. Conclusion This study suggests that an increase in ANP serum levels after weight loss therapy could be associated with improvements in cardiometabolic risks and the reduced prevalence of MetS in adolescents with obesity.

Resumo Analisaram-se fatores associados ao uso de serviços de saúde bucal (USSB) entre idosos brasileiros. Estudo transversal, que considerou a amostra de 7.619 idosos (65-74 anos) do SB Brasil 2010. Utilizou-se modelagem com equações estruturais (MEE), investigando associação entre variáveis latentes ou observadas, de forma direta ou mediada, em relação ao USSB. Utilizaram-se estimadores de mínimos quadrados ajustados pela média e variância, por meio de coeficientes padronizados, erro padrão e intervalos de confiança, com o método bootstrapping com 1.500 iterações. Idosos com melhor condição socioeconômica, menor número de dentes perdidos e presença de impactos das condições de saúde bucal em sua vida foram associados de forma direta ao desfecho. Ainda estiveram associados ao USSB de forma mediada, a condição socioeconômica, sexo e idade; bem como o uso de próteses; além de se encontrar correlação entre uso de próteses e dentes perdidos. A perda dentária exerceu papel de destaque, apontando para a necessidade de ampliação do acesso às próteses dentárias na atenção básica.

Abstract The present study analyzed factors associated with the use of oral health services among elderly Brazilians. This was a cross-sectional study with data from the latest National Oral Health Survey (SB Brazil 2010), which considered a sample of 7,619 elderly individuals (65-74 years) for analysis. Structural Equation Modeling (SEM) was used, investigating the association between latent or observed variables, directly or mediated, in relation to the use of oral health services. Least squares estimators adjusted by mean and variance, were used by means of standardized coefficients, and standard error and confidence intervals, by applying the bootstrapping method with 1,500 iterations. Elderly individuals with a higher socioeconomic status, fewer missing teeth, and the presence of impacts of oral health conditions on their lives were directly associated with the outcome. Other factors associated with the mediated use of oral health services among elderly Brazilians included socioeconomic status, gender, age, and the use of prostheses, in addition to finding a correlation between prosthesis use and missing teeth. Tooth loss, along with other factors, played a prominent role in this study regarding the use of oral health services among elderly Brazilians, pointing to the need to expand access to dental prostheses in primary care.

RESUMO: LIN28 é uma proteína de ligação ao RNA, com duas formas homólogas altamente conservadas, LIN28A e LIN28B. Os proto-oncogenes LIN28A e LIN28B são regulados pela família de miRNAs let-7 em diferentes tipos de cânceres em humanos. No presente trabalho, o objetivo foi determinar a expressão de LIN28A em amostras de tumor mamário de cadelas e a via LIN28/let-7 em linhagens celulares mamárias caninas. Nestas linhagens, através das técnicas de qPCR e RNAseq, foi identificado que a via LIN28/let-7 apresenta-se funcional, com alta expressão dos membros da família let-7 e baixa expressão de seus alvos, entre eles LIN28A e LIN28B. No entanto, as amostras de tecidos de carcinomas mamários caninos demonstraram expressão frequente de LIN28A, sendo observada principalmente em células epiteliais. Não foram observadas associações entre expressão de LIN28A com classificação e gradação histopatológicas, TNM e tempo de sobrevida. Nossos resultados sugerem uma possível relação da proteína LIN28A no desenvolvimento de carcinomas mamários caninos devido à alta frequência observada nas amostras tumorais (28 de 32). Os experimentos in vitro sugerem que a via LIN28/let-7 é ativa nas linhagens celulares caninas avaliadas. Entretanto, estudos funcionais ainda são necessários para elucidar a função exata da via LIN28/let-7 nos carcinomas mamários caninos.

ABSTRACT: LIN28 is a RNA-binding protein including two highly conserved homologous, LIN28A and LIN28B. Proto-oncogenes such as LIN28A and LIN28B are generally targeted by the let-7 miRNAs in different types of human cancers. Here, we determined the expression of LIN28A in canine mammary tumor samples and the LIN28/let-7 pathway in canine mammary cell lines. In those cell lines, we identified a functional LIN28/let-7 pathway which exhibited high expression of let-7 members and low expression of its targets, including LIN28A and LIN28B. However, the mammary carcinoma tissue samples showed a frequent expression of LIN28A being expressed mainly in the epithelial cells. No association was observed between LIN28A expression and histopathological classification and grade, TNM and survival time. Our results suggested a possible role of the LIN28A protein in the development of canine mammary carcinomas due to the high frequency observed in the tumor samples (28 of 32). The in vitro experiments suggested that the LIN28/let-7 pathway is active in the tumor cells evaluated. However, more studies are necessary to elucidate the exact role of LIN28/let-7 pathway in canine mammary carcinomas.

Abstract Gene polymorphisms can predispose to periodontal disease, as demonstrated by the well-documented association between aggressive periodontitis and single nucleotide polymorphisms (SNPs) such as rs153745 in the GLT6D1 gene and rs3217992 in the CDKN2BAS gene. The purpose of this study was to evaluate the presence of these SNPs in Brazilian patients with advanced periodontitis (stages III/IV, Grade B/C) vs. healthy controls. A total of 100 patients with periodontitis (Group BC) were enrolled. Of these, 51 patients were classified as stage III and 49 patients were classified as stage IV, and 52 were Grade B (Group B) and 48 were Grade C (Group C). The control Group consisted of 61 healthy subjects. DNA samples extracted from buccal epithelial cells were used to genotype the SNPs rs1537415 (GLT6D1) and rs3217992 (CDKN2BAS) by real-time quantitative PCR. No significant differences in polymorphism frequency were found between the control Group and each of the patient groups (BC, B, or C), and Group B did not differ from Group C. In conclusion, the evaluated SNPs had no significant influence on the prevalence of periodontal disease in the sampled Brazilian population.

Abstract Capsicum is one of the most important genera of the Solanaceae family. Among the domesticated species, C. chinense is considered the most Brazilian pepper, besides being known for having high levels of phytochemical compounds and, consequently, high antioxidant capacity. This work was intended to perform the chemical characterization of bioactive compounds present in C. chinense accessions from the Capsicum Genebank of Embrapa Temperate Agriculture. Fruits from 19 accessions were evaluated regarding the concentration of total phenolic compounds, total carotenoids, total anthocyanins and antioxidant activity. It was possible to observe a high genetic variability among the evaluated accessions. The highest concentration of phenolic compounds was found in accession number P391; the highest concentrations of total carotenoids were found in accession numbers P240; P348 and P399; the highest concentration of total anthocyanins was in accession number P240; and the highest antioxidant activity was found in accession numbers P386, P391, P366, P350, P346 and P399. There is a correlation between antioxidant activity and the content of phenolic compounds, as well as between antioxidant activity and carotenoids in Capsicum chinense. The genetic variability noticed can be exploited in breeding programs for the selection of accessions with desirable characters.
