Abstract Introduction Perianal fistula is a common colorectal disease which is caused mainly by cryptoglandular disease. Although most cases are treated successfully by surgery, management of complex perianal fistulas (CPAF) remains a challenge with limited results in recurrence and sometimes associated with fecal incontinence. The CPAF treatment with autologous adipose-derived mesenchymal stem cells (ASCs) had become a research hotspot. The technique started to be used in the treatment of Crohn's disease (CD) fistulas, where the studies showed safe and goods result from the procedure. Cultured ASCs have been used but this approach requires the preceding collection of adipose tissue, time for isolation of ASCs and subsequent in vitro expansion, need for laboratory facilities, and expertise in cell culturing. These factors have been getting over by using the commercially available alternative, allogenic ASCs. Treatment with allogeneic ASCs has shown good results in patients with CD fistulas, however with the disadvantage of being expensive. Objective To show that the injection with freshly collected adipose tissue is an alternative to treatment with autologous or allogenic ASCs with several advantages. Methods: In this case report, we show our first experience in the treatment of CPAF with the application of collected adipose tissue in a tertiary referral hospital from Belo Horizonte, Brazil. Results The patient had a good postoperative recuperation with a complete fistula healing after 8 months without adverse effects. Conclusion Injection with freshly collected adipose tissue is a promising and apparently safe sphincter-sparing technique in the treatment of CPAF.

Abstract In the last few decades, there have been considerable improvements in the diagnosis and care of Duchenne muscular dystrophy (DMD), the most common childhood muscular dystrophy. International guidelines have been published and recently reviewed. A group of Brazilian experts has developed a standard of care based on a literature review with evidence-based graded recommendations in a two-part publication. Implementing best practice management has helped change the natural history of this chronic progressive disorder, in which the life expectancy for children of the male sex in the past used to be very limited. Since the previous publication, diagnosis, steroid treatment, rehabilitation, and systemic care have gained more significant insights with new original work in certain fields. Furthermore, the development of new drugs is ongoing, and some interventions have been approved for use in certain countries. Therefore, we have identified the need to review the previous care recommendations for Brazilian patients with DMD. Our objective was to create an evidence-based document that is an update on our previous consensus on those topics.

Resumo Nas últimas décadas, houve progressos significativos no diagnóstico e no tratamento da distrofia muscular de Duchenne (DMD), considerada a distrofia muscular mais comum na infância. Diretrizes internacionais foram publicadas e revisadas recentemente. Um grupo de especialistas brasileiros desenvolveu um padrão de atendimento baseado em revisão de literatura, com recomendações graduadas pautadas em evidências compiladas em uma publicação dividida em duas partes. A implementação de melhores práticas de manejo ajudou a modificar a história natural desta doença crônica, progressiva, que, no passado, oferecia uma expectativa de vida muito limitada para crianças do sexo masculino. Desde a publicação desse consenso anterior, o diagnóstico, o tratamento com esteroides, a reabilitação e os cuidados sistêmicos ganharam novas possibilidades a partir da divulgação dos resultados de trabalhos originais em algumas dessas áreas. Além disso, as pesquisas e o desenvolvimento de novos fármacos estão em andamento, e algumas intervenções já foram aprovadas para uso em determinados países. Nesse contexto, identificamos a necessidade de rever as recomendações anteriores sobre o manejo dos pacientes brasileiros com DMD. Nosso objetivo principal foi elaborar uma atualização baseada em evidências sobre esses tópicos do consenso.

ABSTRACT. Removal of lettuce basal leaves is a technique used by the seed industry; however, the effects on seed production and physiological potential are unknown. Genetic dissimilarity is fundamental in the identification of individuals in terms of traits of interest, although it is rarely considered in relation to seeds that are tolerant to thermoinhibition. The aim of this study was to ascertain the relationship between defoliation of lettuce plants and seed yield/physiological quality, as well as the genetic dissimilarity among genotypes with regard to seed thermoinhibition. We used 35 lines of biofortified lettuce, the cultivars Uberlândia 10000, Belíssima, UFU MC BIOFORT1, and Everglades (tolerant to thermoinhibition), and Grand Rapids and Verônica (susceptible to thermoinhibition). The seed yield and physiological quality of the genotypes with and without defoliation were evaluated, artificially aged, and germinated at four temperatures in a factorial arrangement. The genetic dissimilarity was estimated by Tocher graphing and the UPGMA clustering method, based on the Mahalanobis generalized distance (D2 ii). Four UFU genotypes and Grand Rapids had high seed yields. With removal of basal leaves, there was higher seed yield per plant and there was an effect on their physiological quality. The genotypes exhibited genetic variability for thermoinhibition, with UFU-86#2#1#1 and Everglades showing similar performance.

ABSTRACT Peritoneal carcinomatosis (PC) indicates advanced stage cancer, which is generally associated with a poor outcome and a 6 to 12 months. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an option for treating patients with primary PC, such as mesothelioma, or secondary PC, such as colorectal cancer (CRC) or pseudomixoma. Until recently, such patients were deemed untreatable. Objective: The purpose of this study was to assess the results of CRS + HIPEC in patients with PC. Postoperative complications, mortality and survival rates were evaluated according to the diagnosis. Results: Fifty-six patients with PC, undergoing full CRS + HIPEC between October 2004 and January 2020, were enrolled. The mortality rate was 3.8% and the morbidity rate was 61.5%. Complications were significantly higher in proportion to the duration of surgery (p<0.001). The overall survival rates, as shown in the Kaplan-Meyer curve, were respectively 81%, 74% and 53% at 12, 24 and 60 months. Survival rates according to each diagnosis for the same periods were 87%, 82% and 47% in patients with pseudomixoma, and 77%, 72% and 57% in patients with CRC (log-rank 0.371, p=0.543). Conclusion: CRS with HIPEC is an option for pacients with primary or secondary PC. Although complication rates are high, a longer survival rate may be attained compared to those seen in previously published results; in some cases, patients may even be cured.

RESUMO O diagnóstico de carcinomatose peritoneal (CP), indica um estágio avançado do câncer e em geral está associado a um mau prognóstico com sobrevida média variando de 6 a 12 meses. A cirurgia citorredutora (CRS) associada à quimioterapia intraperitoneal hipertérmica (HIPEC) tem sido descrita como uma opção de tratamento para os pacientes portadores de CP primária como nos portadores de mesotelioma, ou secundária como em portadores de cancer colorretal ou pseudomixoma, até recentemente considerados sem possibilidade terapêutica. Objetivo: Avaliar os resultados do tratamento de pacientes portadores de CP submetidos a CRS + HIPEC. Foram analisadas as taxas complicações pós-operatórias, mortalidade e a sobrevida desses pacientes. Resultados: Foram incluídos 56 pacientes com CP, submetidos a c CRS + HIPEC, no período de Outubro 2004 a Janeiro 2020. A taxa de mortalidade foi de 3,8% e taxa de morbidade de 61,5%, sendo a ocorrência de complicações significativamente maior quanto maior o tempo cirúrgico (p<0,001). A sobrevida global pela curva de Kaplan-Meyer foi de 81%, 74% e 53% em 12, 24 e 60 meses respectivamente. Já a sobrevida por diagnóstico nos mesmos períodos foi de 87%, 82%, 47% para os pacientes portadores de pseudomixoma e de 77%, 72% e 57% para pacientes portadores de câncer colorretal (Log -RANK 0,371, p=0,543). Conclusão: A CRS + HIPEC é uma opção de tratamento para pacientes portadores de CP primária ou secundária. Embora com taxa de complicações elevadas, pode proporcionar aumento da sobrevida quando comparado com resultados prévios da literatura e em alguns casos até a cura.

ABSTRACT Objectives: the purpose of this study was to evaluate the outcome of rectal cancer surgery, in a unit adopting the principles of total mesorectal excision (TME) with a high restorative procedure rate and with a low rate of abdominoperineal excision (APE). Methods: we enrolles patients with extraperitoneal rectal cancer undergoing TME or TME+APE. Patients with mid rectal tumors underwent TME, and patients with tumors of the lower rectum and no criteria for APE underwent TME and intersphincteric resection. Those in which the intersphincteric space was invaded and in those with a free distal margin less than 1cm or a tumor free radial margin were unattainable underwent APE or extralevator abdominoperineal excision (ELAPE). We assessed local recurrence rates, overall survival and involvement of the radial margin. Results: sixty (89.6%) patients underwent TME and seven (10.4%) TME + APE, of which five underwent ELAPE. The local recurrence, in pacientes undergoing TME+LAR, was 3.3% and in patients undergoing APE, 14.3%. The local recurrence rate (p=0.286) or the distant recurrence rate (p=1.000) was similar between groups. There was no involvement of radial margins. Survival after 120 months was similar (p=0.239). Conclusion: rectal malignancies, including those located in the low rectum, may be surgically treated with a low rate of APE without compromising oncological principles and with a low local recurrence rates.

RESUMO Objetivos: o objetivo deste estudo foi avaliar os resultados da cirurgia do câncer de reto, em uma unidade que adota os princípios da excisão total do mesorreto (ETM) com baixa taxa de amputação abdominoperineal (AAP). Métodos: os pacientes com câncer retal extraperitoneal foram submetidos a ETM ou ETM com amputação abdominoperianeal. Pacientes com tumores de reto médio foram submetidos a EMT e pacientes com tumores de reto inferior e sem critérios para AAP foram submetidos a EMT e ressecção interesfincteriana. Aqueles em que o espaço interesfincteriano foi invadido e naqueles com margem distal livre menor que 1cm ou margem radial livre de tumor foram inatingíveis foram submetidos a AAP ou excisão abdominoperineal extraelevadora (ELAPE). Avaliamos as taxas de recorrência local, sobrevida global e envolvimento da margem radial. Resultados: sessenta (89,6%) pacientes realizaram ETM e sete (10,4%) ETM + AAP, dos quais cinco realizaram ELAPE. A recidiva local, em pacientes submetidos a ETM com ressecção anterior baixa, foi de 3,3% e em pacientes submetidos a AAP, 14,3%. A taxa de recorrência local (p=0,286) ou a taxa de recorrência à distância (p=1,000) foi semelhante entre os grupos. Não houve envolvimento das margens radiais. A sobrevida após 120 meses foi semelhante (p=0,239). Conclusão: as neoplasias malignas retais, incluindo aquelas localizadas no reto baixo, podem ser tratadas cirurgicamente com baixo índice de AAP, sem comprometer os princípios oncológicos e com baixo índice de recorrência local.

ABSTRACT Introduction: colonoscopy is the best method for detecting polyps, with a reduction in colorectal cancer mortality of 29% and reaching 47% for distal tumors. However, it fails to demonstrate a significant reduction in proximal colon cancer mortality, and is the most common segment with interval neoplasm. The present study aimed to evaluate the impact on detection of polyps of a second sequential evaluation of cecum and ascending colon, with or without the use of indigo carmine chromoendoscopy. Methods: prospective, non-randomized clinical trial. Patients were divided into two groups. The first (G1) underwent a routine colonoscopy, followed by a second endoscopy assessment of ascending colon and cecum. The second group (G2) underwent a routine colonoscopy, followed by a second assessment of the ascending colon and cecum with indigo carmine chromoendoscopy. Results: In total, 203 patients were analyzed, 101 in the G1 and 102 in the G2. Newer polyps were identified in both groups after the second assessment with a significantly higher number of polyps detected in the patients in the G2 (p=0.0001). The number of patients who had at least one polyp in the two endoscopic assessments was significantly higher in the G2 (53 or 52% vs 27 or 26.7%, p=0.0002). In the second endoscopic assessment, the number of polyps found was also significantly higher in the G2 (50 or 76.9%) compared to the G1 (15 or 23.1%), p<0.0001. Conclusions: the second assessment with dye-based chromoendoscopy increases the detection of polyps in the ascending colon and cecum.

RESUMO Introdução: a colonoscopia é o melhor método para detecção de pólipos, com redução da mortalidade por câncer colorretal de 29% e chegando até 47% para tumores distais. No entanto, existe falha em demonstrar redução significativa na mortalidade no cólon proximal sendo o segmento mais comum de neoplasia de intervalo. O presente estudo avaliou o impacto na detecção de pólipos em uma segunda avaliação sequencial do ceco e cólon ascendente, com ou sem o uso de cromoendoscopia com Indigo carmim. Métodos: estudo prospectivo, não randomizado. Os pacientes foram divididos em dois grupos. O primeiro (G1) foi submetido à colonoscopia de rotina, seguida de segunda avaliação endoscópica do cólon ascendente e ceco. O segundo grupo (G2) foi submetido à colonoscopia de rotina, seguida de segunda avaliação do cólon ascendente e ceco com cromoendoscopia com índigo carmim. Resultados: no total, foram analisados 203 pacientes, sendo 101 do G1 e 102 do G2. Novos pólipos foram identificados em ambos os grupos após a segunda avaliação com número significativamente maior de pólipos detectados nos pacientes do G2 (p=0,0001). O número de pacientes que apresentaram pelo menos um pólipo nas duas avaliações endoscópicas foi significativamente maior no G2 (53 ou 52% vs 27 ou 26,7%, p=0,0002). Na segunda avaliação endoscópica, o número de pólipos encontrados também foi significativamente maior no G2 (50 ou 76,9%) em relação ao G1 (15 ou 23,1%), p<0,000. Conclusão: a segunda avaliação com cromoendoscopia com índigo carmim aumenta a detecção de pólipos no cólon ascendente e no ceco.

ABSTRACT A 2-year-old female patient, admitted in the emergency room, presented diarrhea for 5 days and bloody stools in the last 24 hours. Physical examination revealed no significant findings. Ultrasound was initially performed, showing an elongated, well delimited and solid mass occupying since right hypocondrium until left iliac fossa, displacing adjacent structures. In sequence, magnetic resonance imaging was performed for confirmation of findings suggestive of omentum lipoma. After 1 week, the surgical resection was performed by videolaparoscopic acess. During 2-year follow-up, there was no sign of recurrence.

RESUMO: Objetivo: Identificar padrões espaciais em casos de lactentes com alterações de crescimento e desenvolvimento relacionadas à infecção pelo vírus Zika e outras etiologias infecciosas (neste trabalho denominado de síndrome congênita pelo vírus Zika), notificados no Maranhão de 2015 a 2018 e sua relação com variáveis socioeconômicas e demográficas. Métodos: Estudo ecológico de casos suspeitos notificados de síndrome congênita pelo vírus Zika nos 217 municípios do Maranhão, Brasil. Calculou-se a autocorrelação espacial pelos índices de Moran local e global (I) univariado e bivariado da taxa de detecção de casos suspeitos de síndrome congênita pelo vírus Zika com índice de desenvolvimento humano municipal, densidade demográfica, índice de Gini e tempo de emancipação político-administrativa dos municípios. O índice de Moran local foi calculado para localizar clusters com autocorrelação espacial significativa. Resultados: Houve autocorrelação espacial na análise univariada da taxa municipal de detecção de casos suspeitos de síndrome congênita pelo vírus Zika (I=0,494; p=0,001) e, na análise bivariada, correlação positiva da taxa de detecção de casos suspeitos com índice de desenvolvimento humano municipal (I=0,252; p=0,001), densidade demográfica (I=0,338; p=0,001) e tempo de emancipação dos municípios (I=0,134; p=0,001). Não houve correlação significativa da taxa de detecção de casos suspeitos com o índice de Gini (I= -0,033; p=0,131). Cinco clusters de alta detecção de casos suspeitos foram encontrados em áreas distintas do estado. Conclusões: Os municípios com maior índice de desenvolvimento humano municipal, maior densidade demográfica e mais tempo de emancipação político-administrativa tiveram mais casos suspeitos notificados de síndrome congênita pelo vírus Zika.

ABSTRACT: Objective: To identify spatial patterns in cases of changes in growth and development related to Zika virus infection and other infectious etiologies (denominated Zika virus congenital syndrome in this study) reported in Maranhão from 2015 to 2018 and their relation with socioeconomic and demographic variables. Methods: Ecological study of notified Zika virus congenital syndrome cases in the 217 cities of Maranhão, Brasil. Spatial autocorrelation was calculated using GeoDa 1.14 software and the local and global (I) Moran’s index in univariate and bivariate analyses on Zika virus congenital syndrome incidence rate with Municipal Human Development Index (MHDI), population density, Gini coefficient and the cities’ time of administrative political emancipation. Local Moran’s Index was calculated to identify clusters with significant spatial autocorrelation. Results: Spatial autocorrelation was checked in univariate analysis of the incidence rate of Zika virus congenital syndrome (I=0,494; p=0,001) and positive correlation in bivariate analysis of the incidence rate with Municipal Human Development Index (I=0,252; p=0,001), population density (I=0,338; p=0,001) and the cities’ time of administrative political emancipation (I=0,134; p=0,001). The correlation between incidence rate with Gini coefficient was not significant (I= -0,033; p=0,131). Five high-incidence clusters were found in distinct areas of the state. Conclusions: Cities with higher MHDI, higher population density and more years of administrative political emancipation had more cases of Zika virus congenital syndrome notified.

ABSTRACT Objective To determine whether the size of thyroid nodules in ACR-TIRADS ultrasound categories 3 and 4 is correlated with the Bethesda cytopathology classification. Methods Thyroid nodules (566) subclassified as ACR-TIRADS 3 or 4 were divided into three size categories according to American Thyroid Association guidelines. The frequency of different Bethesda categories in each size range within ACR-TIRADS 3 and 4 classifications was analyzed. Results Most nodules in both ACR-TIRADS classifications fell in the Bethesda 2 category, regardless of size (90.8% and 68.6%, ACR-TIRADS 3 and 4 respectively). The prevalence of Bethesda 6 nodules in the ACR-TIRADS 4 group was 14 times higher than in the ACR-TIRADS 3 group. There were no significant differences between nodule size and fine needle aspiration biopsy classification in any of the ACR-TIRADS categories. Conclusion Size does not appear to be an important criterion for indication of fine needle aspiration biopsy in thyroid nodules with a high suspicion of malignancy on ultrasound examination.

ABSTRACT Objective To stratify ultrasound samples in a pediatric population undergoing evaluation for acute appendicitis to examine the variability in cecal appendix diameter, in different age groups, and to determine whether there is a prevalent value for each age group. Methods A retrospective cross-sectional study with 196 children aged 0 to 15 years. Data were extracted from reports of ultrasound examinations carried out between 2008 and 2015. Children with sonographic diagnosis of appendicitis or other signs of periappendiceal inflammation were excluded. Results The evaluation of the anteroposterior measurement of the cecal appendix revealed a mean diameter of 4.14mm (standard deviation: 0.93mm; 95%CI: 3.86-4.14). Cecal appendix diameter did not differ significant between age groups. Conclusion Evaluation of the anteroposterior diameter of the cecal appendix in centimeters in a sample of 196 children aged 0 to15 years revealed a mean diameter of 4.14mm (standard deviation, 0.93mm. There were no significant differences in cecal appendix diameter following stratification by age. Results indicate a single value can be adopted for mean cecal appendix diameter in pediatric populations.

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

Abstract Optical thermometry is a growing technological field which exploits the ability of certain materials to change their optical properties with temperature. In this work, poly(glycerol dendrimer) microspheres (PGLyD) encapsulating cobalt-doped hopeite (CoHo) was synthesized for its potential use as optical thermometer. The structure of the CoHo:PGLyD was studied using scanning electron microscopy (SEM), infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). On the basis of SEM images, the CoHo:PGLyD exhibited a spherical shape in which around 80% of the microspheres were within 0.82 µm. A multilayer feed-forward artificial neural network (MLP-ANN) was used to extract the chromaticity profile dependence of the CoHo:PGLyD with temperature. A color change was observed for the CoHo:PGLyD, going from dark blue (490-550 nm) to pale pink (650 nm) when the temperature changed from 20-200 °C, respectively. These results suggest that CoHo:PGLyD is a promising material for temperature sensing applications.

RESUMO Objetivo: Investigar possíveis diferenças nas concentrações de selênio no plasma e nos eritrocitos de idosos com e sem a doença de Alzheimer (DA). Métodos: Estudo transversal, realizado com idosos com DA, diagnosticados por médico geriatra, e comparado a um grupo de idosos sem a doença, pareado por sexo, escolaridade e idade. As concentrações de selênio total (Set) intraeritocitárias e plasmáticas foram determinadas por espectrofotometria de absorção atômica. Resultados A média da idade foi 74,41±7,1 anos no grupo DA e 71,46±5,1 anos no grupo-controle. O grupo doença de Alzheimer apresentou menores concentrações plasmáticas (média de 45,29±14,51 µg/dL vs. 55,14±4,01 µg/dL; p = 0,004) e eritrocitárias de Set (mediana de 56,36 µg/L vs. 76,96 µg/L; p < 0,001). O modelo de regressão logística indicou associação entre concentrações eritrocitárias de Set e o diagnóstico de doença de Alzheimer (p = 0,028). Conclusão Idosos com DA apresentam concentrações menores de selênio plasmático e eritrocitário..

ABSTRACT Objective: To investigate possible differences in plasma and erythrocyte concentrations of selenium among elderly with and without a diagnosis of Alzheimer’s disease (AD). Methods: Cross-sectional study, performed with an elderly group with Alzheimer’s disease, diagnosed by a geriatric doctor, and compared to an elderly group without the disease, equaling gender, education, and age. Atomic absorption spectrophotometry determined plasma and erythrocyte concentrations of total selenium (Set). Results: The mean age was 74.41±7.1 years in the Alzheimer’s disease group and 71.46±5.1 years among the control group. The Alzheimer’s disease group presented lower plasma concentrations (mean of 45.29±14.51 µg/dL vs. 55.14±14.01 µg/dL; p=0.004), and erythrocyte Set (median of 56.36 µg/L vs. 76.96 µg/L; p<0.001). The logistic regression model indicated an association between erythrocyte Set concentrations and diagnosis of Alzheimer’s disease (p=0.028). Conclusion: Elderly with Alzheimer’s disease present lower selenium concentrations in the evaluated organic compartments.
