Medição automática de valva mitral a partir de ecocardiograma utilizando processamento digital de imagens / Automatic measurement of the mitral valve based on echocardiography using digital image processing

Fundamento: A avaliação da área valvar mitral por meio da reconstrução multiplano na ecocardiografia tridimensional é restrita a softwares específicos e à experiência dos ecocardiografistas. Eles precisam selecionar manualmente o frame do vídeo que contenha a área de abertura máxima da valva mitral, dimensão fundamental para a identificação de estenose mitral. Objetivo: Automatizar o processo de determinação da área de abertura máxima da valva mitral, por meio da aplicação de Processamento Digital de Imagens (PDI) em exames de ecocardiograma, desenvolvendo um algoritmo aberto com leitura de vídeo no formato avi. Método: Este estudo piloto observacional transversal foi realizado com vinte e cinco exames diferentes de ecocardiograma, sendo quinze com abertura normal e dez com estenose mitral reumática. Todos os exames foram realizados e disponibilizados por dois especialistas, com autorização do Comitê de Ética em Pesquisa, que utilizaram dois modelos de aparelhos ecocardiográficos: Vivid E95 (GE Healthcare) e Epiq 7 (Philips), com sondas multiplanares transesofágicas. Todos os vídeos em formato avi foram submetidos ao PDI através da técnica de segmentação de imagens. Resultados: As medidas obtidas manualmente por ecocardiografistas experientes e os valores calculados pelo sistema desenvolvido foram comparados utilizando o diagrama de Bland-Altman. Observou-se maior concordância entre valores no intervalo de 0,4 a 2,7 cm². Conclusão: Foi possível determinar automaticamente a área de máxima abertura das valvas mitrais, tanto para os casos advindos da GE quanto da Philips, utilizando apenas um vídeo como dado de entrada. O algoritmo demonstrou economizar tempo nas medições quando comparado com a mensuração habitual. (AU)

Background: The evaluation of mitral valve area through multiplanar reconstruction in 3-dimensional echocardiography is restricted to specific software and to the experience of echocardiographers. They need to manually select the video frame that contains the maximum mitral valve opening area, as this dimension is fundamental to identification of mitral stenosis. Objective: To automate the process of determining the maximum mitral valve opening area, through the application of digital image processing (DIP) in echocardiography tests, developing an open algorithm with video reading in avi format. Method: This cross-sectional observational pilot study was conducted with 25 different echocardiography exams, 15 with normal aperture and 10 with rheumatic mitral stenosis. With the authorization of the Research Ethics Committee, all exams were performed and made available by 2 specialists who used 2 models of echocardiographic devices: Vivid E95 (GE Healthcare) and Epiq 7 (Philips), with multiplanar transesophageal probes. All videos in avi format were submitted to DIP using the image segmentation technique. Results: The measurements obtained manually by experienced echocardiographers and the values calculated by the developed system were compared using a Bland-Altman diagram. There was greater agreement between values in the range from 0.4 to 2.7 cm². Conclusion: It was possible to automatically determine the maximum mitral valve opening area, for cases from both GE and Philips, using only 1 video as input data. The algorithm has been demonstrated to save time on measurements when compared to the usual method. (AU)

Reconhecimento e política no interior da tradição dialética: Sócrates, o Ateniense, Marx e Lênin / Recognition and politics within the dialectical tradition: Socrates, the Athenian, Marx and Lenin

O objetivo deste artigo é o de chamar atenção para uma série de questionamentos que podem e, a nosso ver, ainda devem ser feitos, acerca de uma suposta, exclusiva e definitiva doutrina política de Platão. Para tanto, inicialmente, é levantada a seguinte pergunta: A República, um dos mais célebres e comentados diálogos escritos por Platão, seria, de fato, o único momento de "sua" obra em que este autor expressaria a "sua" teoria política (comunista)? Amparados na leitura e interpretação imanentista de Hector Benoit a respeito dos diálogos platônicos, partimos da hipótese de que Platão, não sendo Sócrates, expôs ­ através de um personagem denominado Ateniense ­ em seu último diálogo na temporalidade da léxis, As Leis, um projeto de cidade radicalmente distinto daquele d'A República. Tal projeto se baseia na unidade dos contraditórios para a formação educacional dos habitantes de uma cidade composta por amigos que tivessem todas as coisas realmente em comum; cidade que deveria ser realizada na prática, e não apenas na metafísica alma do filósofo, como Sócrates haveria proposto idealisticamente n'A República. Assim, longe de ter abandonado os seus posicionamentos comunistas da juventude, como defendem alguns intérpretes, Platão, ao final da vida, teria, na realidade, os encontrado de modo mais rigorosamente determinado. No final do artigo, Marx e Lênin assumem o protagonismo, o que sugere ser a teoria política um dos fios condutores da milenar tradição dialética

This article aims at drawing attention to a series of inquiries that may and, in our view, still should be asked about a supposed, unique and definitive political doctrine of Plato. Then, initially, the following question is raised: The Re-public, one of the most famous and commented dialogues written by Plato, would be in fact the only moment of "his" work in which this author would express "his" political theory (communist)? Supported by Hector Benoit's immanentist reading and interpretation of the Platonic dialogues, we hypothetize that Plato, not being Socrates, exposed ­ through a character called Athenian ­ in his last dialogue, TheLaws, in the temporality of the lexis, a project of city radically different from that on The Republic. Such a project is based on the unity of contradictories for the educational formation of the inhabitants of a city composed of friends who really had all things in common; city that should be put into practice, and not just in the metaphysical soul of the philosopher, as Socrates idealistically proposed in The Republic. Thus, far from having abandoned, as some interpreters argue, his youthful communist positions, Plato would have in fact found them, at the end of his life, in a more rigorously determined way. At the end of our article, Marx and Lenin take on the leading role, which suggests that political theory is one of the guiding threads of the millennial dialectical tradition

Is paclitaxel less cardiotoxic in the treatment of breast cancer before or after doxorubicin? / Qual estratégia terapêutica é menos cardiotóxica no tratamento do câncer de mama: uso de paclitaxel antes ou depois da doxorrubicina?

Background: The combination of doxorubicin (DOX) with paclitaxel (PTX) effectively treats breast cancer (BC). However, DOX-associated cardiotoxicity (CTX) is aggravated by the use of PTX. Consensus is lacking about which drug sequence involves the most CTX. Objectives: To evaluate whether DOX followed by PXT or the reverse sequence has the greatest cardiotoxic potential in the treatment of BC. Methods: Prospective study of women with primary BC who received four cycles of DOX and 12 infusions of PTX. Participants were divided into Group 1 (G1; PXT before DOX) and Group 2 (G2; DOX before PXT) at the discretion of the oncologist. CTX was defined as an absolute reduction in left ventricular ejection fraction (LVEF) > 10% to a value <53%. Patients underwentclinical evaluations and echocardiography before treatment (Phase 1) and one year after treatment (Phase 2). Results: Sixty-nine women were evaluated: 19 in G1 and 50 in G2. The groups had similar clinical characteristics. The doses of radiation, DOX, and PTX used were similar. Eight (11.6%) patients developed CTX: two (10.5%) in G1 and six (12.0%) in G2 (p=0.62). The mean LVEF was similar between groups in Phase 1 (G1=65.1±3.5%; G2=65.2±3.9%; p=0.96), with a significant reduction noted after one year in both groups: G1=61.4±8.1% (p=0.021) and G2=60.8±7.6% (p<0,001). Although lower, mean LVEF remained similar between groups after Phase 2 (p=0.79). Conclusions: In women with BC who underwent chemotherapy, the incidence of CTX at the end of the first year of treatment was similar regardless of whether DOX was used before or after PTX. (AU)

Redução na Hospitalização e Aumento na Mortalidade por Doenças Cardiovasculares durante a Pandemia da COVID-19 no Brasil / Reduction in Hospitalization and Increase in Mortality Due to Cardiovascular Diseases during the COVID-19 Pandemic in Brazil

Resumo Fundamento Na pandemia pela COVID-19, o aumento da ocorrência e da mortalidade por doenças cardiovasculares (DCV) vem sendo reconhecido no mundo. No Brasil, é essencial que o impacto da COVID-19 na DCV seja analisado. Objetivos Avaliar o impacto desta pandemia nos números de internações hospitalares (IH), óbitos hospitalares (OH) e letalidade intra-hospitalar (LH) por DCV a partir de dados epidemiológicos do Sistema Único de Saúde (SUS). Métodos Estudo observacional de séries temporais por meio da análise comparativa das taxas de IH, OH e LH por DCV registrados entre janeiro e maio de 2020, usando como referência os valores obtidos no mesmo período entre 2016 e 2019 e os valores projetados por métodos de regressão linear para o ano de 2020. O nível significância estatística utilizado foi de 0,05. Resultados Em comparação com o mesmo período de 2019, houve um decréscimo de 15% na taxa de IH e de 9% no total de OH por DCV entre março e maio de 2020, acompanhado de um aumento de 9% na taxa de LH por esse grupo de doenças, sobretudo entre pacientes com idade de 20-59 anos. As taxas de IH e LH registradas em 2020 diferiram significativamente da tendência projetada para o corrente ano (p=0,0005 e 0,0318, respectivamente). Conclusões Durante os primeiros meses da pandemia, observou-se um declínio na IH associado a um aumento da LH por DCV no Brasil. Esses dados possivelmente são consequência do planejamento inadequado no manejo das DCV durante a pandemia, sendo necessária a implementação de ações imediatas para modificar esse cenário.

Abstract Background In the COVID-19 pandemic, the increase in the incidence of cardiovascular diseases (CVD) and mortality from them has been recognized worldwide. In Brazil, the impact of COVID-19 on CVD must be evaluated. Objectives To assess the impact of the current pandemic on the numbers of hospital admissions (HA), in-hospital deaths (ID), and in-hospital fatality (IF) from CVD by use of national epidemiological data from the Brazilian Unified Public Health System. Methods Time-series observational study using comparative analysis of the HA, ID, and IF due to CVD recorded from January to May 2020, having as reference the values registered in the same period from 2016 to 2019 and the values projected by linear regression methods for 2020. The statistical significance level applied was 0.05. Results Compared to the same period in 2019, there was a 15% decrease in the HA rate and a 9% decrease in the total ID due to CVD between March and May 2020, followed by a 9% increase in the IF rate due to CVD, especially among patients aged 20-59 years. The HA and IF rates registered in 2020 differed significantly from the projected trend for 2020 (p = 0.0005 and 0.0318, respectively). Conclusions During the first months of the pandemic, there were a decline in HA and an increase in IF due to CVD in Brazil. These data might have resulted from the inadequate planning of the CVD management during the pandemic. Thus, immediate actions are required to change this scenario.

Effects of therapeutic and aerobic exercise programs in temporomandibular disorder-associated headaches

Abstract Objective To assess the effects of three 8-week exercise programs on the frequency, intensity, and impact of headaches in patients with headache attributed to temporomandibular disorder (TMD). Methodology Thirty-six patients diagnosed with headache attributed to TMD participated in the study and were divided into three groups of 12 patients: a therapeutic exercise program (G1, mean age: 26.3±5.6 years), a therapeutic and aerobic exercise program (G2, mean age: 26.0±4.6 years), and an aerobic exercise program (G3, 25.8±2.94 years). Headache frequency and intensity were evaluated using a headache diary, and the adverse headache impact was evaluated using the Headache Impact Test (HIT-6). The intensity was reported using the numerical pain rating scale. These parameters were evaluated twice at baseline (A01/A02), at the end of the 8-week intervention period (A1), and 8-12 weeks after the end of the intervention (A2). Results At A1, none of the G2 patients reported having headaches, in G1, only two patients reported headaches, and in G3, ten patients reported headache. The headache intensity scores (0.3 [95% CI: -0.401, 1.068]), (0.0 [95% CI: -0.734, 0.734]) and HIT-6 (50.7 [95% CI: 38.008, 63.459]), (49.5 [95% CI: 36.808, 62.259]), significantly decreased in G1 and G2 at A1. At A2 headache intensity scores (0.5 [95% CI: -0.256, 1.256]), (0.0 [95% CI: -0.756, 0.756]) and HIT-6 (55.1 [95% CI: 42.998, 67.268]), (51.7 [95% CI: 39.532, 63.802]) in G1 and G2 haven't change significantly. The effects obtained immediately after the completion of the intervention programs were maintained until the final follow-up in all groups. Conclusion The programs conducted by G1 (therapeutic exercises) and G2 (therapeutic and aerobic exercise) had significant results at A1 and A2.

Resistance of rice genotypes to fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae)

ABSTRACT The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is an important rice pest which consumes leaf area during all phases of plant development. The objective of this study was to identify rice genotypes that provide antixenosis and antibiosis to fall armyworm. Antixenosis was investigated by measuring non-preference in free-choice and no-choice tests while antibiosis was determined by measuring biological parameters and nutritional indices of S. frugiperda in twelve rice genotypes. The genotype Miúdo Branco showed antixenosis to S. frugiperda, whereas the genotypes IR 64 and Bacaba Branco showed antibiosis to S. frugiperda by affecting insect development and prolonging insect life cycle. Insects that fed on Bacaba Branco genotype demonstrated the lowest nutritional indices. Since Miúdo Branco, IR 64 and Bacaba Branco showed moderate resistance, rice producers could use these genotypes as part of a control strategy for S. frugiperda.

Acute liver failure due to radiographically occult infiltration of urothelial cancer

Introduction Acute liver failure (ALF) due to diffuse infiltrating solid malignancy without any focal lesions on radiographic imaging is rare. Case report A 70-year-old man was admitted due to mental confusion, abdominal pain, and ALF. Three years before, he had undergone a left nephrectomy for urothelial carcinoma followed by adjuvant chemotherapy. The abdominal computed tomography (CT) showed hepatomegaly and ascites. Ascitic fluid had transudate characteristics, with no malignant cells. Percutaneous liver biopsy (LB) showed diffuse liver infiltration of metastatic urothelial carcinoma. The patient rapidly deteriorated and died in a week due to ALF. Discussion History of solid cancer and hepatomegaly and/or liver failure without other obvious explanation should encourage to perform LB. Conclusion LB is warranted to avoid misdiagnosis, prolonged hospital stays, and delay in palliative care.

Prelabor cesarean section: the role of advanced maternal age and associated factors

ABSTRACT OBJECTIVE to evaluate whether advanced maternal age (AMA) is associated with prelabor cesarean section and to identify the factors associated with prelabor cesarean section in AMA women, according to the mode of type of labor financing (private or public). METHODS Based on the Birth in Brazil survey, the research was conducted on representative sample of mothers for the country (Brazil), regions, type of hospital and location (capital or not), in 2011/2012. This study included 15,071 women from two age groups: 20-29 years and ≥ 35 years. The information was collected from interviews with puerperal woman, prenatal cards, and medical records of mothers and newborns. Multiple logistic regression modelling was used to verify the association between prelabor cesarean section and maternal, prenatal and childbirth characteristics, according to the mode of financing. RESULTS Our results showed a higher use of prelabor cesarean section for AMA (≥ 35 years) women in the public service (OR = 1.63; 95%CI 1.38-1.94) and in the private service (OR = 1.44; 95%CI 1.13-1.83), compared with women aged 20-29 years. In the adjusted model, we recorded three factors associated with the prelabor cesarean section in AMA women in both, public and private sectors: the same professional in prenatal care and childbirth (OR = 4.97 and OR = 4.66); nulliparity (OR = 6.17 and OR = 10.08), and multiparity with previous cesarean section (from OR = 5.73 to OR = 32.29). The presence of obstetric risk (OR = 1.94; 95%CI .44-2.62) also contributed to the occurrence of prelabor cesarean section in women who gave birth in the public service. CONCLUSIONS AMA was an independent risk factor for prelabor cesarean in public and private services. In the public, prelabor cesarean in AMA was more influenced by clinical criteria. Higher chance of prelabor cesarean section in nulliparous women increases the chance of cesarean section in multiparous women, as we showed in this study, which increases the risk of anomalous placental implantation.

Houve uma preocupante diminuição no número de cirurgias cardíacas e nas sessões de quimioterapia e radioterapia nas semanas iniciais da pandemia. A procura por atendimento no pronto-socorro cardiológico, assim como as internações na UTI e enfermaria cardiológicas, também reduziram, gerando preocupação acerca da evolução e prognóstico destes pacientes portadores de outras patologias, que não a COVID-19, nestes tempos de pandemia.

Abstract Background We still do not have information regarding the impact of the COVID-19 pandemic on medical care activity in Brazil. Objective To describe the repercussions of the COVID-19 pandemic on the care routine of a tertiary hospital, which is a regional reference in cardiology and oncology. Methods Cross-sectional cohort study. We conducted a survey of medical visits from March 23, 2020 (when local commerce was closed) to April 23, 2020 (P20), in comparison with the same period in 2019 (P19). Results We found decreases in the number of cardiology consultations, exercise tests, Holter, ambulatory blood pressure monitoring, electrocardiogram, and echocardiogram (90%, 84%, 94%, 92%, 94%, and 81%, respectively). In relation to cardiac surgery and cardiac catheterization, there were 48% and 60% decreases, respectively. There was an increase in the number of percutaneous transluminal coronary angioplasties (33%) and definitive pacemaker implantations (29%). There were 97 admissions to the ICU during P19, in contrast with 78 during P20, a 20% decrease. Visits to the cardiac emergency room (45%) and admissions to the cardiology ward (36%) also decreased. The decrease in oncology consultations was 30%. Chemotherapy sessions decreased from 1,944 to 1,066 (45%), and radiotherapy sessions decreased by 19%. Conclusion COVID-19 has led to a considerable decrease in the number of consultations in outpatient clinics for cardiology, oncology, and other specialties. There was a concerning decrease in the number of cardiac surgeries, chemotherapy sessions, and radiotherapy sessions during the initial weeks of the pandemic. The number of people seeking care in the cardiac emergency room and the number of admissions to the cardiology ward and ICU also decreased, generating concern regarding the evolution and prognosis of these patients with pathologies other than COVID-19 during this pandemic time.

Urogenital tuberculosis in a patient with end-stage renal disease

Abstract Tuberculosis is one of the most common infections worldwide with particularly high incidence rates in countries with unfavorable socioeconomic conditions and among persons with impaired immune systems. While most patients with this disease will present with pulmonary tuberculosis, immunocompromised individuals also commonly present with extrapulmonary manifestations. We report the case of a 28-year-old male patient with end-stage renal disease who presented with long-standing systemic symptoms and genitourinary manifestations, who was diagnosed with urogenital tuberculosis both by clinical and microbiologic criteria. Clinicians should always suspect tuberculosis in patients with chronic symptoms, especially in those with immunosuppression.

Ischemic stroke related to HIV and SARS-COV-2 co-infection: a case report

Abstract A 56-year-old male with human immunodeficiency virus required hospitalization due to the onset of both dyspnea and asthenia. A computed tomography of the chest exam showed the radiological pattern of coronavirus SARS-CoV-2 pulmonary involvement. Based on immunochromatographic analysis, the patient evolved as a reagent for immunoglobulin M (IgM) and immunoglobulin G (IgG) anti-SARS-CoV-2 antibodies. The individual developed complete hemiparesis with a predominance in the right arm and conduction aphasia. T1-weighted magnetic resonance sequence of the brain showed an area of hypointensity with a high intrinsic cortical signal and hyperintensity in the T2-sequence. A Doppler velocimetric examination showed total/critical sub occlusion, suggesting an ischemic stroke.
