ABSTRACT Objective: To evaluate autoinflammatory diseases (AID) according to age at diagnosis and sex, and response to therapy in a large population. Methods: This is a cross-sectional observational study of a Latin American registry using a designed web system for data storage, collected between 2015 and 2018. Any altered findings during follow-up were recorded. The forms were translated into Portuguese and Spanish, including demographic, clinical, laboratory, genetic and treatment characteristics. Results: We included 152 patients, 51.3% male and 75% Caucasian. The median age at disease onset was 2.1 years (0–15.6 years) and median age at diagnosis 6.9 years (0–21.9 years); 111 (73%) were children (0–9 years old), and 41 (27%) were adolescents and young adults (AYA) (10–21 years old). Periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome (PFAPA) occurred in 46/152 (30%), chronic non-bacterial osteomyelitis (CNO) in 32/152 (21%), and familial Mediterranean fever (FMF) in 24/152 (15.7%). PFAPA was significantly higher in young children than in AYA (38.7% vs. 7.3%, p<0.001), while CNO were lower (13.5% vs. 41.5%, p<0.001). The frequency of females was significantly higher in CNO (28.4% vs. 14.1%, p=0.031) and lower in FMF (8.1% vs. 23.1%, p=0.011). The most used drugs were glucocorticoids, non-steroidal anti-inflammatory drugs (NSAID), and colchicine. Glucocorticoids and colchicine treatment were used in all AID with good to moderate response. However, cryopyrin-associated periodic syndromes (CAPS) seemed unresponsive to glucocorticoids. NSAIDs and methotrexate were the main medications used to treat CNO. Conclusions: Differences among AID patients were observed in the LA population regarding sex and age at disease diagnosis.

RESUMO Objetivo: Avaliar as doenças autoinflamatórias (DAI) de acordo com sexo e idade no momento do diagnóstico e a resposta terapêutica em uma grande população. Métodos: Este é um estudo observacional transversal de um registro latino-americano que usou um sistema de dados coletados entre 2015 e 2018. Quaisquer achados alterados ao longo do acompanhamento foram registrados. Os formulários foram traduzidos para os idiomas português e espanhol, incluindo características demográficas, clínicas, laboratoriais, genéticas e de tratamento. Resultados: Incluímos 152 pacientes, sendo 51,3% do sexo masculino e 75% da raça branca. A média de idade de início da doença foi de 2,1 anos (0–15,6 anos) e a média de idade de diagnóstico 6,9 anos (0–21,9 anos); 111 (73%) eram crianças (0–9 anos) e 41 (27%) adolescentes/adultos jovens (10–21 anos). A síndrome de febre periódica, estomatite aftosa, faringite e adenite (PFAPA) ocorreu em 46/152 (30%), osteomielite não bacteriana crônica (CNO) em 32/152 (21%) e febre familiar do Mediterrâneo (FMF) em 24/152 (15,7%). A PFAPA foi significativamente maior em crianças pequenas (38,7 vs. 7,3%, p<0,001), e a CNO, em adolescentes/adultos jovens (13,5 vs. 41,5%, p<0,001). A frequência do sexo feminino foi significativamente maior na CNO (28,4 vs. 14,1%, p=0,031) e menor na FMF (8,1 vs. 23,1%, p=0,011). Os medicamentos mais utilizados foram glicocorticoides, anti-inflamatórios não esteroidais (AINE) e colchicina. O tratamento com glicocorticoides e colchicina foi usado em todas as DAI com resposta boa a moderada. No entanto, as síndromes periódicas associadas à criopirina (CAPS) pareciam não responder aos glicocorticoides. AINE e metotrexato foram os principais medicamentos utilizados no tratamento da CNO. Conclusões: Diferenças de pacientes com DAI foram observadas na população latino-americana em pacientes agrupados por sexo e idade ao diagnóstico da doença.

Resumo: O objetivo foi descrever a gravidade das complicações relacionadas ao aborto, os fatores relacionados às complicações, os tipos de tratamento e a experiência de atendimento no Brasil. Foi realizado um estudo transversal em vinte hospitais (dez no Distrito Federal, três em Rondônia e sete no Maranhão). Durante três meses, todos os dados de todas as mulheres tratadas por aborto/aborto espontâneo foram coletados. A gravidade das complicações foi definida de acordo com os critérios da Organização Mundial da Saúde. As mulheres com hemorragia, infecção ou lesão de órgãos foram convidadas a responder a uma entrevista sobre a experiência do atendimento. A análise estatística foi realizada usando o teste de qui-quadrado e modelos de regressão de Poisson. Entre as 1.683 mulheres incluídas, 82,5% tiveram complicações leves, 13,6% tiveram complicações moderadas, 3,2% tiveram condições potencialmente ameaçadoras à vida (PLTC, acrônimo em inglês) e 0,7% tiveram resultados maternos graves (SMO, acrônimo em inglês). A maioria das mulheres (94,2%) precisou de esvaziamento uterino. Entre elas, 91,5% precisaram de esvaziamento cirúrgico (com ou sem uso de uterotônicos) e 8,5% usaram apenas uterotônicos. O método de esvaziamento cirúrgico mais frequente foi a curetagem (66,9%), seguido pela aspiração manual a vácuo (32,3%). Os fatores associados à PLTC/SMO vs. complicações leves foram ter idade gestacional ≥ 13 semanas (razão de prevalência - RP = 3,09; intevalo de 95% de confiança - IC95%: 1,42-6,72), ter sido tratado no Maranhão (RP = 0,27; IC95%: 0,12-0,63) e em Rondônia (RP = 0,64; IC95%: 0,20-0,99). Os fatores associados às complicações moderadas vs. leves foram expulsão dos produtos da concepção antes da chegada ao serviço de saúde (RP = 2,55; IC95%: 1,64-3,96) e ter sido tratado no Maranhão (RP = 0,58; IC95%: 0,38-0,87). A maioria das mulheres que responderam à entrevista foi tratada com gentileza (95,6%), no entanto, 66,7% se sentiram estressadas e 10,1% relataram que suas preferências não foram respeitadas durante a internação. Nove em cada dez mulheres atendidas em hospitais públicos brasileiros devido a complicações relacionadas ao aborto são submetidas a algum procedimento cirúrgico, sendo o mais comum a curetagem uterina. Aproximadamente quatro em cada 100 mulheres apresentam complicações graves. É fundamental garantir o fornecimento de equipamentos para aspiração manual a vácuo e incentivar programas de educação médica continuada para aumentar a conscientização dos profissionais de saúde sobre tratamentos mais seguros para evacuação uterina.

Abstract: This study aimed to describe the severity of abortion-related complications, factors associated with complications, the types of management and the experience of care in Brazil. A cross-sectional study in twenty hospitals (10 in Federal District, 3 in Rondônia and 7 in Maranhão). For 3 months, all women treated for abortion/miscarriage had their data collected. The severity of complications was defined according to World Health Organization criteria. Women with hemorrhage, infection or organs injury were invited to answer an interview about experience of care. Statistical analysis was performed using chi-square test and Poisson regression models. Among 1,683 women included, 82.5% had mild complications, 13.6% had moderate complications, 3.2% had potentially life-threatening conditions (PLTC) and 0.7% had severe maternal outcomes (SMO). Most women (94.2%) required uterine evacuation. Among these, 91.5% required surgical evacuation (with or without the use of uterotonics) and 8.5% used only uterotonics. The most frequent surgical evacuation method was curettage (66.9%), followed by manual vacuum aspiration (MVA) (32.3%). Factors associated with PLTC/SMO vs mild complications were having a gestational age ≥ 13 weeks (pravlence ratio - PR = 3.09; 95% confidence interval - 95%CI: 1.42-6.72), having been treated in Maranhão (PR = 0.27; 95%CI: 0.12-0.63) and in Rondônia (PR = 0.64; 95%CI: 0.20-0.99). Factors associated with moderate vs. mild complications were expulsion of products of conception before arrival to health facility (PR = 2.55; 95%CI: 1.64-3.96) and having been treated in Maranhão (PR = 0.58; 95%CI: 0.38-0.87). Most women who responded to the interview were treated kindly (95.6%), however, 66.7% felt stressed and 10.1% reported that their preferences were not respected during hospitalization. Nine out of ten women treated in Brazilian public hospitals due to abortion-related complications undergo some surgical procedure, the most common of which is uterine curettage. Approximately four in every hundred women experience severe complications. It is essential to ensure the supply of equipment for MVA and to encourage continuing medical education programs to increase the awareness of healthcare professionals about safer treatments for uterine evacuation.

Abstract Background Hepatocellular carcinoma (HCC) is a prevalent tumor with high mortality rates. Computed tomography (CT) is crucial in the non-invasive diagnosis of HCC. Recent advancements in artificial intelligence (AI) have shown significant potential in medical imaging analysis. However, developing these AI algorithms is hindered by the scarcity of comprehensive, publicly available liver imaging datasets. Objectives This study aims to detail the tools, data organization, and database structuring used in creating HepatIA, a medical imaging annotation platform and database at a Brazilian tertiary teaching hospital. HepatIA supports liver disease AI research at the institution. Material and methods The authors collected baseline characteristics and CT scans of 656 patients from 2008 to 2021. The database, designed using PostgreSQL and implemented with Django and Vue.js, includes 692 CT volumes from a four-phase abdominal CT protocol. Radiologists made segmentation annotations using the OHIF medical image viewer, incorporating MONAI Label for pre-annotation segmentation models. The annotation process included detailed descriptions of liver morphology and nodule characteristics. Results The HepatIA database currently includes healthy individuals and those with liver diseases such as HCC and cirrhosis. The database dashboard facilitates user interaction with intuitive plots and histograms. Key patient demographics include 64% males and an average age of 56.89 years. The database supports various filters for detailed searches, enhancing research capabilities. Conclusion A comprehensive data structure was successfully created and integrated with the IT systems of a teaching hospital, enabling research on deep learning algorithms applied to abdominal CT scans for investigating hepatic lesions such as HCC.

ABSTRACT Introduction: Short Bowel Syndrome (SBS) is a rare gastrointestinal disorder associated with Intestinal Failure (SBS-IF) that leads to morbidity, mortality, and a burden on healthcare costs. Intestine Transplantation (IT) is a treatment option for patients with SBS-IF as it replaces the missing or diseased intestine and offers the potential for return to normal activities and intestinal function. This study aims to describe the clinical course and demographical and clinical characteristics of subjects with SBS-IF who underwent IT in Brazil. Methods: This retrospective observational study included all SBS-IF patients who underwent IT in two reference centers in Brazil from April 2011 to December 2021. Results: A total of 7 young male participants were included in the study. The most frequent underlying condition was surgical complications, followed by intestinal volvulus and incisional hernia. The most frequent indication for IT was a hepatic disease associated with total Parenteral Nutrition (PN). The main type of IT performed was intestine only. The median time from underlying condition to IT was 67.3 (16.5-88.5) months. The mean (SD) number of yearly hospitalizations per patient was 0.5 (0.3). The most common reason for hospitalization was PN-related complications. Sixty exams were performed in-hospital and 53 in the outpatient setting. Conclusion: The findings of this study may be helpful to understand better the journey of patients with SBS-IF to IT in Brazil, providing real-world evidence to develop health policy guidelines and improve the quality of life of these patients.

Abstract Background Professional soccer athletes are exposed to repetitive head impacts and are at risk of developing chronic traumatic encephalopathy. Objective To evaluate regional brain glucose metabolism (rBGM) and gray matter (GM) volume in retired soccer players (RSPs). Methods Male RSPs and age and sex-matched controls prospectively enrolled between 2017 and 2019 underwent neurological and neuropsychological evaluations, brain MRI and [18F]FDG-PET in a 3.0-Tesla PET/MRI scanner. Visual analysis was performed by a blinded neuroradiologist and a blinded nuclear physician. Regional brain glucose metabolism and GM volume were assessed using SPM8 software. Groups were compared using appropriate statistical tests available at SPM8 and R. Results Nineteen RSPs (median [IQR]: 62 [50–64.5] years old) and 20 controls (60 [48–73] years old) were included. Retired soccer players performed worse on mini-mental state examination, digit span, clock drawing, phonemic and semantic verbal fluency tests, and had reduced rBGM in the left temporal pole (pFDR = 0.008) and the anterior left middle temporal gyrus (pFDR = 0.043). Semantic verbal fluency correlated with rBGM in the right hippocampus, left temporal pole, and posterior left middle temporal gyrus (p ≤ 0.042). Cray matter volume reduction was observed in similar anatomic regions but was less extensive and did not survive correction for multiple comparisons (pFDR ≥ 0.085). Individual [18F]FDG-PET visual analysis revealed seven RSPs with overt hypometabolism in the medial and lateral temporal lobes, frontal lobes, and temporoparietal regions. Retired soccer players had a higher prevalence of septum pellucidum abnormalities on MRI. Conclusion Retired soccer players had reduced rBCM and CM volume in the temporal lobes and septum pellucidum abnormalities, findings possibly related to repetitive head impacts.

Resumo Antecedentes Jogadores profissionais de futebol estão expostos a impactos cranianos repetitivos e ao risco de desenvolver encefalopatia traumática crônica. Objetivo Avaliar o metabolismo glicolítico cerebral regional (MCCr) e o volume de substância cinzenta (vSC) em jogadores de futebol aposentados (JFAs). Métodos Jogadores de futebol aposentados masculinos e controles pareados por idade e sexo foram incluídos prospectivamente entre 2017 e 2019. Foram realizadas avaliações neurológica e neuropsicológica, ressonância magnética (RM) e [18F]FDG-PET cerebrais (3.0-Tesla PET/RM). As imagens foram analisadas visualmente por um neurorradiologista e um médico nuclear cegos ao grupo de cada participante. O metabolismo glicolítico cerebral regional e o vSC foram avaliados através do programa SPM8. Os grupos foram comparados através de testes estatísticos apropriados disponíveis em SPM8 e R, de acordo com a distribuição e o tipo dos dados. Resultados Dezenove JFAs (mediana [IIQ]: 62 [50–64.5] anos) e 20 controles (60 [48–73] anos) foram incluídos. Os JFAs tiveram pior desempenho no mini-exame do estado mental e nos testes de dígitos, desenho do relógio, fluência verbal e fluência semântica e apresentaram MCCr significativamente reduzido no polo temporal e no giro temporal médio anterior esquerdos. Fluência semântica (animais) apresentou correlação positiva com MCCr no hipocampo direito, no polo temporal esquerdo e no aspecto posterior do giro temporal médio esquerdo. Menor vSC foi observado nas mesmas regiões, porém este achado não sobreviveu à correção para comparações múltiplas. Análise individual do [18F]FDG-PET cerebral revelou sete JFAs com claro hipometabolismo nas faces medial e lateral dos lobos temporais, nos lobos frontais e nas regiões temporoparietais. Os JFAs apresentaram ainda maior prevalência de anormalidades do septo pelúcido. Conclusão Os JFAs apresentam MCCr e vSC reduzidos nos lobos temporais, além de anormalidades do septo pelúcido, achados possivelmente relacionados a impactos cranianos repetitivos.

Resumo Introdução A síndrome da apneia obstrutiva do sono é uma desordem de elevada prevalência na população. Estudos constataram possível associação entre obstrução nasal e síndrome da apneia obstrutiva do sono, porém a existência de uma relação entre a intensidade da obstrução nasal e a gravidade da síndrome da apneia obstrutiva do sono ainda não foi comprovada. Objetivo Avaliar as dimensões internas nasais de adultos com ronco primário e síndrome da apneia obstrutiva do sono por meio de rinometria acústica e correlacionar os achados com a gravidade da síndrome da apneia obstrutiva do sono. Método Foram avaliados 21 indivíduos com queixas de ronco e/ou pausas respiratórias durante o sono, gênero masculino, entre 18 e 60 anos, brancos. Após avaliação clínica, exame físico otorrinolaringológico e nasofaringolaringoscopia flexível, todos foram submetidos à polissonografia tipo III. Os participantes foram divididos em dois grupos de acordo com a gravidade dos sintomas: grupo 1, ronco primário e/ou síndrome da apneia obstrutiva do sono leve (n = 9) e grupo 2, síndrome da apneia obstrutiva do sono moderada/grave (n = 12). Dimensões internas nasais foram aferidas por rinometria acústica, foram consideradas para análise as áreas de secção transversa mínima e os volumes de três diferentes segmentos nasais. Resultados O índice de eventos respiratórios correspondeu a 8,1 ± 4,0 no grupo 1 e 47,5 ± 19,1 no grupo 2. No grupo 1, os valores de área de secção transversa, em cm2, corresponderam a: área de secção transversa 1 = 1,1 ± 0,4; área de secção transversa 2 = 2,1 ± 0,9; área de secção transversa 3 = 3,5 ± 1,8. No grupo 2: área de secção transversa 1 = 1,2 ± 0,3, área de secção transversa 2 = 2,0 ± 0,5; áre de secção transversa 3 = 2,8 ± 0,7. No grupo 1 os valores do volume, em cm3, corresponderam a: volume 1 = 3,5 ± 1,0; volume 2 = 9,3 ± 5,0; volume 3 = 40,2 ± 21,5 e no grupo 2 a: volume 1 = 3,6 ± 0,5; V2 = 7,6 ± 1,5; volume 3 = 31,5 ± 6,7. Os valores de área de secção transversa e volume não diferiram entre os grupos. Conclusão Não foram demonstradas diferenças significantes quanto às áreas seccionais transversas e os volumes nasais entre indivíduos com ronco primário e síndrome da apneia obstrutiva do sono leve e síndrome da apneia obstrutiva do sono moderada-grave. Contrariamente à hipótese levantada, os resultados sugerem não existir relação entre as dimensões internas nasais e o nível de gravidade da síndrome da apneia obstrutiva do sono.

Abstract Introduction Obstructive sleep apnea syndrome is a high-prevalence disorder found in the population. Studies have shown a possible association between nasal obstruction and obstructive sleep apnea syndrome, but the existence of a association between the degree of nasal obstruction and obstructive sleep apnea syndrome severity has not yet been proven. Objective To evaluate the internal nasal dimensions of adults with primary snoring and obstructive sleep apnea syndrome by acoustic rhinometry and to correlate the findings with obstructive sleep apnea severity. Methods Twenty-one male Caucasian subjects with complaints of snoring and/or respiratory pauses during sleep, aged between 18 and 60 years of age, were evaluated. After clinical evaluation, otorhinolaryngological examination and flexible nasopharyngolaryngoscopy, all patients underwent type III polysomnography. The participants were divided into two groups according to symptom severity: group 1, primary snoring and/or mild obstructive sleep apnea syndrome(n = 9) and group 2, moderate/severe obstructive sleep apnea syndrome (n = 12). Internal nasal dimensions were measured by acoustic rhinometry, analyzing minimum cross sectional area (CSA) and three nasal segment volumes. Results The respiratory event index corresponded to 8.1 ± 4.0 in group 1 and 47.5 ± 19.1 in group 2. In group 1, the cross-sectional areas values, in cm2, corresponded to: CSA 1 = 1.1 ± 0.4; CSA 2 = 2.1 ± 0.9; CSA 3 = 3.5 ± 1.8 and, in group 2: CSA 1 = 1.2 ± 0.3, CSA 2 = 2.0 ± 0.5; CSA 3 = 2.8 ± 0.7. In group 1, volumes (V), in cm3, corresponded to: V1 = 3.5 ± 1.0; V2 = 9.3 ± 5.0; V3 = 40.2 ± 21.5 and in group 2 a: V1 = 3.6 ± 0.5; V2 = 7.6 ± 1.5; V3 = 31.5 ± 6.7. Cross-sectional area and volume did not differ between groups. Conclusion There were no significant differences in the cross-sectional areas and nasal volumes between individuals with primary snoring-mild obstructive sleep apnea syndrome and moderate-severe obstructive sleep apnea syndrome. Differently to the raised hypothesis, our results suggest that there is no association between internal nasal dimensions and severity of obstructive sleep apnea syndrome.

Abstract Introduction: in the last few years important changes have occurred in nutritional patterns. There has been an increase in the consumption of simple carbohydrates such as fructose, which has been associated with numerous metabolic disorders, including hepatic steatosis. Materials and methods: we sought to evaluate the impact of fructose consumption, as diluted in water at different concentrations, for two time periods, on the metabolic parameters of Wistar rats using ANOVA. Results: our data indicate that both time and fructose concentration promote variations in animal body mass, and in food, water, and caloric intake. The time variable influenced the modulation of biochemical parameters such as serum concentrations of glucose and total cholesterol. Both fructose concentration and time of exposure influenced the concentrations of serum triglycerides, creatinine, AST, TNF, and IL-6. When evaluating redox status and oxidative damage markers, we observed that fructose concentration and exposure time had an effect on total glutathione levels, which decreased with an increase in concentration and time. For superoxide dismutase, we evaluated the effects of time and interaction. A significant interaction was observed for TBARS. For carbonylated proteins, exposure time was a fundamental factor in generating an effect. Conclusions: we demonstrated that fructose modulates the parameters of triglycerides and total liver cholesterol, and that time influences the number of hepatocytes. Our data suggest that fructose concentration, exposure time, and an interaction between these two parameters have a significant effect on the metabolic parameters responsible for the development of non-alcoholic fatty liver disease.

ABSTRACT Objective Provide a comprehensive view of the events surrounding the sugar consumption, under conditions of energy equivalence; through the analysis of behavioral aspects of intake, and of biochemical, metabolic and physiological parameters, as well as the effect of this nutrient on the plasticity of adipose tissue. Materials and methods Newly weaned male Wistar rats were classified in two groups and subjected to the following normocaloric diets: standard chow diet or to high-sugar diet (HSD) ad libitum for 18 weeks. Results The animals submitted to the HSD were associated with a lower caloric intake during the 18 weeks of experimentation. However, the HSD induced a significant increase in body weight, white adipose tissue weight, adiposity index, Lee index, and the levels of triglycerides and very low-density lipoprotein in the serum. In addition, it induced glucose intolerance, insulin resistance and compensatory increase of insulin secretion by pancreatic β-cells. Also increased heart rate and induced hyperplasia, and hypertrophy of retroperitoneal visceral adipose tissue. In the liver, the HSD was associated with increased hepatic lipid content (i.e., triglycerides and cholesterol) and hepatomegaly. Conclusion The post-weaning consumption of HSD induces an adaptive response in metabolism; however, such an event is not enough to reverse the homeostatic imbalance triggered by the chronic consumption of this macronutrient, leading to the development of metabolic syndrome, irrespective of caloric intake. These findings corroborate recent evidence indicating that sugar is a direct contributor to metabolic diseases independent of a positive energy balance. Arch Endocrinol Metab. 2020;64(1):71-81

RESUMO Em dezembro de 2019, uma série de pacientes com pneumonia grave foi identificada em Wuhan, província de Hubei, na China. Esses pacientes evoluíram para síndrome respiratória aguda grave e síndrome do desconforto respiratório agudo. Posteriormente, a COVID-19 foi atribuída a um novo betacoronavírus, o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2). Cerca de 20% dos pacientes com diagnóstico de COVID-19 desenvolvem formas graves da doença, incluindo insuficiência respiratória aguda hipoxêmica, síndrome respiratória aguda grave, síndrome do desconforto respiratório agudo e insuficiência renal aguda e requerem admissão em unidade de terapia intensiva. Não há nenhum ensaio clínico randomizado controlado que avalie potenciais tratamentos para pacientes com infecção confirmada pela COVID-19 no momento da publicação destas recomendações de tratamento. Dessa forma, essas recomendações são baseadas predominantemente na opinião de especialistas (grau de recomendação de nível C).

ABSTRACT In December 2019, a series of patients with severe pneumonia were identified in Wuhan, Hubei province, China, who progressed to severe acute respiratory syndrome and acute respiratory distress syndrome. Subsequently, COVID-19 was attributed to a new betacoronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Approximately 20% of patients diagnosed as COVID-19 develop severe forms of the disease, including acute hypoxemic respiratory failure, severe acute respiratory syndrome, acute respiratory distress syndrome and acute renal failure and require intensive care. There is no randomized controlled clinical trial addressing potential therapies for patients with confirmed COVID-19 infection at the time of publishing these treatment recommendations. Therefore, these recommendations are based predominantly on the opinion of experts (level C of recommendation).

RESUMO Objetivo: Investigar os subtipos histológicos e perfis de mutação do carcinoma pulmonar de células não pequenas no Brasil, bem como as correlações entre os subtipos histológicos, a expressão do gene anaplastic lymphoma kinase (ALK, quinase do linfoma anaplásico), o estado de mutação do gene EGFR e a expressão de programmed death-ligand 1 (PD-L1, ligante de morte celular programada 1). Métodos: Avaliamos 173 espécimes provenientes de pacientes com adenocarcinoma pulmonar no Nordeste brasileiro. A expressão de PD-L1 e ALK foi avaliada por meio de imuno-histoquímica, ao passo que o estado de mutação do EGFR foi avaliado por meio de sequenciamento. Os subtipos histológicos foram classificados de acordo com a International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society. Resultados: Os subtipos histológicos mais comuns de adenocarcinoma pulmonar foram o predominantemente sólido (em 46,8%), o predominantemente acinar (em 37,0%) e o predominantemente lepídico (em 9,8%). A expressão de ALK foi detectada em 10,4% das amostras, e 22,0% dos tumores apresentavam mutações do gene EGFR. As mutações mais comuns do EGFR foram a mutação pontual L858R no éxon 21 (em 45,5%) e a deleção do éxon 19 (em 36,3%). O tumor proportion score relativo à expressão de PD-L1 foi ≥ 50% em 18,2% das amostras, = 1-49% em 32,7% e = 0% em 49,5%. O subtipo predominantemente sólido relacionou-se significativamente com EGFR selvagem (p = 0,047). A expressão positiva de PD-L1 não se relacionou significativamente com a expressão de ALK ou o estado de mutação do EGFR. Conclusões: Nossos resultados sugerem que o perfil molecular do carcinoma pulmonar de células não pequenas no Nordeste brasileiro difere do de populações em outras regiões do país: a expressão positiva de ALK é maior que os demais biomarcadores. Mais estudos com informações clínicas e genéticas são necessários para confirmar essas diferenças, além de estudos que se concentrem em populações em diferentes áreas do país.

ABSTRACT Objective: To investigate the histological subtypes and mutational profiles of non-small cell lung cancer in Brazil, looking for correlations among histological subtypes, expression of anaplastic lymphoma kinase (ALK), EGFR mutation status, and programmed death-ligand 1 (PD-L1) expression. Methods: We evaluated 173 specimens obtained from patients with lung adenocarcinoma in northeastern Brazil. Expression of PD-L1 and ALK was evaluated by immunohistochemistry; EGFR mutation status was evaluated by sequencing. We categorized the histological subtypes in accordance with the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification. Results: The most common histological subtypes of lung adenocarcinoma were solid predominant (in 46.8%), acinar predominant (in 37.0%), and lepidic predominant (in 9.8%). ALK expression was detected in 10.4% of the samples, and 22.0% of the tumors harbored EGFR mutations. The most common EGFR mutation was an exon 21 L858R point mutation (in 45.5%), followed by an exon 19 deletion (in 36.3%). The tumor proportion score for PD-L1 expression was ≥ 50% in 18.2% of the samples, 1-49% in 32.7%, and 0% in 49.5%. The solid predominant subtype was significantly associated with wild-type EGFR status (p = 0.047). Positivity for PD-L1 expression was not found to be significantly associated with ALK expression or EGFR mutation status. Conclusions: Our results suggest that the molecular profile of non-small cell lung cancer in northeastern Brazil differs from those of populations in other regions of the country, with ALK positivity being higher than the other biomarkers. Further studies including clinical and genetic information are required to confirm these differences, as well as studies focusing on populations living in different areas of the country.

Abstract INTRODUCTION: The treatment of mucosal leishmaniasis (ML) is difficult due to the toxicity and route of administration of standard drugs. Miltefosine is an oral agent used for leishmaniasis treatment; however, no data exist regarding its use for ML in Brazil. In this study, we aimed to evaluate the efficacy of miltefosine for ML treatment compared to that of pentavalent antimonial in a pilot study. METHODS: We performed a randomized clinical trial with two parallel groups. The tested intervention consisted of miltefosine 1.3-2 mg/kg/day (two capsules) for 28 days or intravenous 20 mg SbV/kg/day of meglumine antimoniate (N-MA) for 30 days. The final endpoint was defined as complete healing of the lesion four years after treatment. We also analyzed an early endpoint at 90 days after treatment. RESULTS: Forty patients were included in this study: each experimental group comprised 20 patients. Applying a multivariate model in an intention-to-treat analysis, we observed that patients treated with miltefosine had a cure probability 2.08 times greater (95% confidence interval [CI] = 1.03-4.18) than those treated with N-MA at 90 days after treatment. At the final endpoint, we observed no differences in cure probability between miltefosine and N-MA (relative risk = 0.66; 95% CI = 0.33-1.32). With respect to adverse reactions, significant differences between groups were related to gastrointestinal effects, which were more frequent in the miltefosine group. CONCLUSIONS: Miltefosine may be an interesting alternative for treating ML because of its oral administration and cure rate after long-term follow-up.

Abstract INTRODUCTION: The detection of Trypanosoma cruzi in tissue samples is important in many situations, such as testing of the reactivation of the infection. The detection of T. cruzi nests in endomyocardial biopsies (EMB) may be useful to evaluate graft rejection. Given their scarcity, such nests are not routinely identified. To increase the diagnosis sensitivity, immunohistochemistry (IHC) may serve as a promising strategy. Here, we validate an antiserum for the detection of T. cruzi infection by IHC. METHODS: We used 1) positive controls (PCs) - 13 EMB, 12 skin biopsies, and 1 heart with T. cruzi nests as sections stained with hematoxylin and eosin (HE); 2) negative controls - a) 10 explant hearts and 10 EMB with no amastigote nests or clinical/laboratory signs of chagasic infection; and b) eight samples with leishmaniasis, toxoplasmosis, or histoplasmosis; and 3) Cases - 31 EMB of chagasic patients with no parasite nests in HE sections but detected positive for T. cruzi DNA by polymerase chain reaction. As a primary antibody, a hyperimmune serum from T. cruzi-infected rabbits was used. RESULTS: IHC results were positive for 21 of 26 PCs (80.8%) and one case of cutaneous leishmaniasis. In 4 of 31 cases, IHC revealed nests (12.9%), which were undetected by conventional histological examination. CONCLUSIONS: This study shows that IHC with the tested antiserum increases the sensitivity of the diagnosis and may be recommended for routine use in EMB analyses of cardiac transplant patients with Chagas disease.
