Arthropod-borne viruses (arboviruses) are a severe public health problem worldwide, consisting of a significant part of all the emerging infectious diseases. It is estimated that arboviruses infect hundreds of millions of people globally each year, resulting in several thousand deaths. Despite their clear health threat, there are no prophylactic or pharmacological therapies available for most of them. Control of arbovirus infections is beyond pharmacological options; handling the larvae of mosquitos is an important and successful strategy, although currently available insecticides and larvicides are already associated with resistance. Therefore, searching for new strategies to prevent arbovirus infection is urgent and necessary. Marine organisms are an excellent source for structurally novel compounds due to their unique secondary metabolism, with outstanding antiviral and larvicidal activities. In the present review, we explored the ability of various marine natural products (MNPs) such as indole derivatives, diketopiperazines, scequinadoline A, cyclohexadepsipeptides, and others, to act as both antiviral and larvicidal, in an attempt to highlight their structure activity potential against the most relevant arboviruses affecting the human health.

Abstract Objectives: The objective of the study was to verify whether (FFM), maturity status (MS) and chronological age (CA) are determinants of physical fitness performance, and to analyze FFM and physical performance aligned by CA and MS in children and adolescents. Methods: A descriptive correlational study was carried out in 863 schoolchildren. Weight, height, and waist circumference (WC) were evaluated. Body mass index (BMI), FFM, fat mass (FM), MS (Age at peak height velocity, APHV) were calculated. The physical tests of velocity 20 m, agility 5 m × 10rep, and horizontal jump (HJ) were evaluated. Results: The APHV was estimated in boys at 14.0 ± 0.36APHV and in girls at 11.96 ± 0.49APHV. The relationships between CA and APHV with FFM was r = 0.80 in boys and r = 0.44 to 0.45 in girls. The relationships between FFM and physical tests in boys were [HJ (r = 0.70), agility 5m × 10rep (r = -0.68), velocity (r = -0.61)] and in girls [HJ (r = 0.42), agility 5m × 10rep (r = -0.52), velocity (r = -0.20)]. The differences in FFM and physical fitness tests were more pronounced when aligned by APHV than by CA. Conclusion: It was verified that both FFM, CA, and APHV are determinants of physical fitness performance. In addition, the APHV should be introduced in physical education as a means of ranking physical performance among schoolchildren.

Abstract Background Recent reports in the literature have indicated that infection by coronavirus disease 2019 (COVID-19) causes cardiac complications, such as heart failure, arrhythmia, myocardial infarction, and even fulminant myocarditis. These complications have been identified as the cause of death in some patients infected with SARS-CoV-2. Objectives To analyze echocardiographic and electrocardiographic changes, treatments used, and clinical outcomes in patients with myocarditis and COVID-19. Methods The items described for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed. This review included articles in English, Portuguese, and Spanish that reported cardiac involvement, injury, or myocardial inflammation in patients who acquired COVID-19 (SARS-CoV-2). Results Five databases were consulted to find 1,726 articles. After applying the eligibility criteria, a total of 22 studies were considered qualified. ST-segment (section of the electrocardiogram corresponding the end of the S wave to the beginning of the T wave) elevation and tachyarrhythmia were the most common changes found in the electrocardiographic analysis of patients affected with COVID-19. Concerning echocardiography, there was a high frequency of decreased ejection fraction and occurrence of pericardial effusion. Conclusion This systematic review provides a potential tool for the analysis of cardiac changes and implications caused in patients affected by SARS-CoV-2 infection, with emphasis on the presence of tachyarrhythmia on electrocardiogram (ECG) and decreased ejection fraction on echocardiogram.

ABSTRACT Due to the COVID-19 pandemic, the projects that offer guidance for physical activity (PA) had to be adapted to the remote format. This study aimed at assessing the effects of a remote PA intervention on the cardiovascular risk and physical fitness of the individuals engaged in these projects. Thus, 29 participants of the Brazilian project known as Projeto Exercício e Coração (Exercise and Heart Project) (66±5 years) were instructed to perform 2 walking sessions, 1 aerobic exercise video class and 2 muscle strength video classes per week with each activity lasting 30 min and performed at moderate intensity. At baseline (pre) and after 8 weeks (post), markers of cardiovascular risk and physical fitness were evaluated and compared by using paired t-tests or Wilcoxon signed rank tests considering p≤0.05. When comparing pre- and post-intervention evaluations, there was a significant reduction in waist circumference (95.9±11.3 vs. 94.7±11.3 cm, p=0.013) and significant increases in cardiorespiratory fitness (117±21 vs. 123±23 steps, p=0.019), upper limb strength (23±6 vs. 25±6 repetitions, p=0.003), abdominal endurance (20±9 vs. 22±10 repetitions, p= 0.002) and overall physical fitness (-0.04±3.55 vs. 1.30±4.10, p=0.000). In conclusion, the remote intervention improved general physical fitness, increasing cardiorespiratory fitness, muscle strength and endurance, in addition to reducing central obesity.

RESUMO Devido à pandemia da COVID-19, os projetos de orientação de atividade física (AF) tiveram que adaptar suas atuações para o formato remoto. O objetivo deste estudo foi avaliar os efeitos de uma intervenção remota de AF no risco cardiovascular e na aptidão física em participantes desses projetos. Para isso, 29 participantes do Projeto Exercício e Coração (66±5 anos) foram orientados a realizar, 2 caminhadas, 1 videoaula de exercícios aeróbicos e 2 videoaulas de exercícios de força muscular por semana, sendo cada atividade realizada por 30 min e em intensidade moderada. No início e após 8 semanas, foram medidos marcadores de risco cardiovascular e de aptidão física, que foram comparados por testes t-student ou Wilcoxon, considerando-se p≤0,05. Comparando-se as avaliações pré e pós-intervenção, houve redução da circunferência da cintura (95,9±11,3 vs. 94,7±11,3 cm, p=0,013) e aumento da capacidade cardiorrespiratória (117±21 vs. 123±23 passos, p=0,019), da força dos membros superiores (23±6 vs. 25±6 repetições, p=0,003), da resistência abdominal (20±9 vs. 22±10 repetições, p=0,002) e da aptidão física geral (-0,04±3,55 vs. 1,30±4,10, p=0,000). Em conclusão, a intervenção remota aumentou a aptidão física geral, aumentando a capacidade cardiorrespiratória, a força e a resistência muscular, além de reduzir a obesidade central.

Abstract The Brazilian Society of Angiology and Vascular Surgery has set up a committee to provide new evidence-based recommendations for patient care associated with chronic venous insufficiency. Topics were divided in five groups: 1. Classification, 2. Diagnosis, 3. Conservative or non-invasive treatment, 4. Invasive treatment and 5. Treatment of small vessels. This last series is closely related to the activities of Brazilian angiologists and vascular surgeons, who are heavily involved in the treatment of small superficial veins. These guidelines are intended to assist in clinical decision-making for attending physicians and health managers. The decision to follow a guideline recommendation should be made by the responsible physician on a case-by-case basis taking into account the patient's specific condition, as well as local resources, regulations, laws, and clinical practice recommendations.

Resumo A Sociedade Brasileira de Angiologia e de Cirurgia Vascular organizou uma comissão para fornecer novas recomendações baseadas em evidências sobre questões críticas de atendimento ao paciente com insuficiência venosa crônica. São abordados aqui os temas de classificação, diagnóstico, tratamento conservador, tratamento invasivo e tratamento de pequenos vasos. Esta última série está muito relacionada à atividade de angiologistas e cirurgiões vasculares, que possuem forte atuação no tratamento de pequenas veias superficiais. Estas diretrizes destinam-se a auxiliar na tomada de decisões clínicas de médicos assistentes e gestores de saúde. A decisão de seguir uma recomendação de diretriz deve ser feita pelo médico responsável caso a caso, levando em consideração a condição específica do paciente, bem como recursos locais, regulamentos, leis e recomendações de prática clínica.

Resumen Cornejo, M. I., Henríquez, M., Herrera, F., Muñoz, F., Bernardes, N., Auricchio, J. R., y Castelli-Correia de Campos, L. F. (2022). Percepción de la calidad de vida en para- deportistas y no deportistas chilenos con lesión cerebral. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20 (2), 1-18. La calidad de vida (CV) y la actividad física son aspectos relevantes en la salud de la población, y esta última con un impacto positivo en las personas con discapacidad. Debido a esto, los objetivos de este estudio fueron comparar las características e identificar la asociación entre los dominios de la percepción de la CV entre un grupo de personas con lesión cerebral que practican fútbol, para-deportistas (PD) y personas con lesión cerebral no para-deportistas (NPD), además determinar si existen diferencias en la percepción de la CV según las diferentes clases deportivas (FT1, FT2 y FT3). El estudio se desarrolló en Chile, donde se aplicó el cuestionario WHOQOL-BREF para determinar la CV de los participantes. Los resultados identificaron una relación positiva y significativa entre los distintos dominios de la CV (p < .001, r = .44 - .67). Además, se observó una mejor percepción de la CV en los PD (p < .001, TE = 1.18, grande) en comparación con lo reportado por el grupo NPD. Por otro lado, no se obtuvieron diferencias significativas entre los dominios para las diferentes clases deportivas en el grupo PD. Estos datos refuerzan la idea de que la práctica deportiva influye en la participación social y en la percepción de la CV en PD con lesión cerebral. El desarrollo conjunto de los factores asociados entre la salud y el bienestar socioemocional podrían colaborar con la consolidación de la práctica deportiva y de actividad física, los cuales, a su vez son beneficiosos para las personas con discapacidad tal como lo plantean los objetivos del desarrollo sostenible en su agenda de trabajo provista al año 2030.

Resumo Cornejo, M. I., Henríquez, M., Herrera, F., Muñoz, F., Bernardes, N., Auricchio, J. R., y Castelli-Correia de Campos, L. F. (2022). Percepção da qualidade de vida em paratletas e não-atletas chilenos com lesões cerebrais. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20 (2), 1-16. Qualidade de vida (QV) e atividade física são aspectos relevantes da saúde da população, tendo esta última um impacto positivo sobre as pessoas com deficiências. Portanto, os objetivos deste estudo foram comparar as características e identificar a associação entre os domínios da percepção de QV entre um grupo de pessoas com lesões cerebrais que praticam futebol, paratletas (P) e pessoas com lesões cerebrais não paratletas (NP), e determinar se existem diferenças na percepção de QV de acordo com as diferentes classes esportivas (FT1, FT2 e FT3). O estudo foi realizado no Chile, onde o questionário WHOQOL-BREF foi utilizado para determinar o QV dos participantes. Os resultados identificaram uma relação positiva e significativa entre os diferentes domínios da QV (p < 0,001, r = 0,44 - 0,67). Além disso, uma melhor percepção de QV foi observada nos Ps (p < 0,001, TE = 1,18, grande) em comparação com a relatada pelo grupo NP. Por outro lado, não foram obtidas diferenças significativas entre os domínios para as diferentes classes esportivas do grupo P. Estes dados reforçam a ideia de que a prática esportiva influencia a participação social e a percepção da QV nos P com lesão cerebral. O desenvolvimento conjunto de fatores associados à saúde e ao bem-estar socioemocional poderia contribuir para a consolidação da prática do esporte e da atividade física, que, por sua vez, são benéficos para as pessoas com deficiência, conforme estabelecido nas Metas de Desenvolvimento Sustentável em sua agenda para 2030.

Abstract Cornejo, M. I., Henríquez, M., Herrera, F., Muñoz, F., Bernardes, N., Auricchio, J. R., y Castelli-Correia de Campos, L. F. (2022). Perception of quality of life in chilean para-athletes and non-athletes with brain injury. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20 (2), 1-16. Quality of life (QOL) and physical activity are relevant aspects in the health of the population, and the latter has a positive impact on people with disabilities. For this reason, the objectives of this study were to compare the characteristics and identify the association between the domains of QOL perception between a group of people with brain injury who practice soccer, para-athletes (PD) and non-para-athletes with brain injury (NPD), as well as to determine if there are differences in the perception of QOL according to the different sports classes (FT1, FT2 and FT3). The study was carried out in Chile, where the WHOQOL-BREF questionnaire was applied to determine the QOL of participants. The results identified a positive and significant relationship between the different domains of QOL (p < .001, r = .44 - .67). In addition, a better perception of QoL was observed in the PDs (p < .001, TE = 1.18, large) compared to that reported by the NPD group. On the other hand, no significant differences between domains were obtained for the different sport classes in the PD group. These data reinforce the idea that sport practice influences social participation and perception of QoL in PD with brain injury. The joint development of the factors associated between health and socioemotional well-being could collaborate in the consolidation of sports practice and physical activity, which, in turn, are beneficial for people with disabilities, as proposed by the Sustainable Development Goals in their work agenda foreseen for the year 2030.

RESUMO Objetivos: Mensurar a perfusão do complexo retina/coróide com ressonância magnética em olhos com fechamento angular primário agudo (FAPA). Métodos: Três sequências de ressonância magnética, duas anatômicas e uma de perfusão com gadolínio, foram adquiridas em pacientes com fechamento angular primário agudo. Regiões de interesse foram desenhadas na sequência de perfusão e sobrepostas à sequência anatômica. O volume de sangue relativo nos 2 primeiros segundos foi considerado como referência, e sua variação nos 28 segundos subsequentes foi analisada. Resultados: Cinco olhos de 5 pacientes com fechamento angular primário agudo foram incluídos (3 com crise unilateral e 2 com crise bilateral). Três olhos contralaterais e 2 olhos de 2 pacientes saudáveis, pareados por sexo e idade, foram incluídos no grupo controle. Pacientes com fechamento angular primário agudo incluíam 4 (80%) mulheres, com idade média de 65,8 ± 12,37 anos, pressão intraocular média de 56,2 ± 14,67 mmHg, pressão arterial média de 113,4 ± 8,17 mmHg e pressão de perfusão ocular de 57,2 ± 13,46mmHg. No grupo controle, pressão intraocular média foi de 15,6 ± 2,61 mmHg (p=0,0625), pressão arterial média de 107,4 ± 6,57 mmHg (p=1,00) e pressão de perfusão ocular de 91,8 ± 6,72 mmHg (p=0,0625). O volume de sangue relativo do complexo retina/coróide foi de -0,127 ± 0,048 nos olhos em fechamento angular primário agudo e -0,213 ± 0,116 nos olhos controles (p=0,3125). Conclusões: A sequência de ressonância magnética com gadolínio não demonstrou diferença na perfusão de retina/coroide em olhos com fechamento angular primário agudo.

ABSTRACT Purpose: To measure retina/choroid complex perfusion with magnetic resonance imaging in eyes with acute primary angle-closure (APAC). Methods: Three sequences of magnetic resonance imaging, two anatomical and one perfusional using gadolinium, were acquired in patients who were diagnosed with acute primary angle-closure. Regions of interest were drawn on the perfusional sequence and overlaid to the anatomical sequence. The relative blood volume measured during the first 2 s was considered as the baseline value and the change during the subsequent 28 s was analyzed. Results: Five eyes of 5 patients with acute primary angle-closure were included (3 with unilateral and 2 with bilateral acute primary angle-closure). Three contralateral eyes and 2 eyes of 2 healthy patients, paired for age and sex, were included in the control group. Acute primary angle-closure patients included 4 (80%) women, with an average age of 65.8 ± 12.37 y, mean intraocular pressure of 56.2 ± 14.67 mmHg, mean arterial pressure of 113.4 ± 8.17 mmHg, and average ocular perfusion pressure of 57.2 ± 13.46 mmHg. In the control group, the mean intraocular pressure was 15.6 ± 2.61 mmHg (p=0.0625), the mean arterial pressure was 107.4 ± 6.57 mmHg (p=1.00), and the average ocular perfusion pressure was 91.8 ± 6.72 mmHg (p=0.0625). The relative blood volume of the retina/choroid complex was -0.127 ± 0.048 in acute primary angle-closure patients and -0.213 ± 0.116 in the controls (p=0.3125). Conclusion: The magnetic resonance imaging sequence with gadolinium did not show a change in the retina/choroid complex perfusion in the eyes of patients with acute primary angle-closure.

Abstract Introduction: The Technical Performance Score (TPS) was developed and subsequently refined at the Boston Children's Hospital. Our objective was to translate and validate its application in a developing country. Methods: The score was translated into the Portuguese language and approved by the TPS authors. Subsequently, we studied 1,030 surgeries from June 2018 to October 2020. TPS could not be assigned in 58 surgeries, and these were excluded. Surgical risk score was evaluated using Risk Adjustment in Congenital Heart Surgery (or RACHS-1). The impact of TPS on outcomes was studied using multivariable linear and logistic regression adjusting for important perioperative covariates. Results: Median age and weight were 2.2 (interquartile range [IQR] = 0.5-13) years and 10.8 (IQR = 5.6-40) kilograms, respectively. In-hospital mortality was 6.58% (n=64), and postoperative complications occurred in 19.7% (n=192) of the cases. TPS was categorized as 1 in 359 cases (37%), 2 in 464 (47.7%), and 3 in 149 (15.3%). Multivariable analysis identified TPS class 3 as a predictor of longer hospital stay (coefficient: 6.6; standard error: 2.2; P=0.003), higher number of complications (odds ratio [OR]: 1.84; 95% confidence interval [CI]: 1.1-3; P=0.01), and higher mortality (OR: 3.2; 95% CI: 1.4-7; P=0.004). Conclusion: TPS translated into the Portuguese language was validated and showed to be able to predict higher mortality, complication rate, and prolonged postoperative hospital stay in a high-volume Latin-American congenital heart surgery program. TPS is generalizable and can be used as an outcome assessment tool in resource diverse settings.

O foco é facilitar a condução de treinamentos de nutricionistas que trabalham com pacientes adultos com doenças renais crônicas (DRC). Foram levantadas onze questões relacionadas à triagem, ao processo de cuidado e à gestão de resultados em nutrição. As recomendações foram baseadas em diretrizes internacionais e em bancos de dados eletrônicos, como PubMed, EMBASE(tm), CINHAL, Web of Science e Cochrane. A partir do envio de listas de termos padronizados internacionalmente, vinte nutricionistas especialistas selecionaram aqueles que consideraram muito claros e relevantes para a prática clínica com pacientes ambulatoriais com DRC. Foi calculado o Índice de Validade de Conteúdo (IVC), com 80% de concordância nas respostas. O Grading of Recommendations, Assessment, Development and Evaluation (GRADE) foi usado para atribuir força de evidência às recomendações. Foram selecionados 107 termos de Avaliação e Reavaliação, 28 de Diagnóstico, 9 de Intervenção e 94 de Monitoramento e Aferição em Nutrição. A lista de termos selecionados e identificação de instrumentos auxiliará no planejamento de treinamentos e na implementação de terminologia padronizada em nutrição no Brasil, para nutricionistas que trabalham com pacientes renais crônicos.

Abstract This nutrition consensus document is the first to coordinate the efforts of three professional organizations - the Brazilian Association of Nutrition (Asbran), the Brazilian Society of Nephrology (SBN), and the Brazilian Society of Parenteral and Enteral Nutrition (Braspen/SBNPE) - to select terminology and international standardized tools used in nutrition care. Its purpose is to improve the training delivered to nutritionists working with adult patients with chronic kidney disease (CKD). Eleven questions were developed concerning patient screening, care, and nutrition outcome management. The recommendations set out in this document were developed based on international guidelines and papers published in electronic databases such as PubMed, EMBASE(tm), CINHAL, Web of Science, and Cochrane. From a list of internationally standardized terms, twenty nutritionists selected the ones they deemed relevant in clinical practice involving outpatients with CKD. The content validity index (CVI) was calculated with 80% agreement in the answers. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess the strength of evidence and recommendations. A total of 107 terms related to Nutrition Assessment and Reassessment, 28 to Diagnosis, nine to Intervention, and 94 to Monitoring and Evaluation were selected. The list of selected terms and identified tools will be used in the development of training programs and the implementation of standardized nutrition terminology for nutritionists working with patients with chronic kidney disease in Brazil.

ABSTRACT Introduction Prostate cancer still represents a major cause of morbidity, and still about 20% of men with the disease are diagnosed or will progress to the advanced stage without the possibility of curative treatment. Despite the recent advances in scientific and technological knowledge and the availability of new therapies, there is still considerable heterogeneity in the therapeutic approaches for metastatic prostate cancer. Objectives This article presents a summary of the I Brazilian Consensus on Advanced Prostate Cancer, conducted by the Brazilian Society of Urology and Brazilian Society of Clinical Oncology. Materials and Methods Experts were selected by the medical societies involved. Forty issues regarding controversial issues in advanced disease were previously elaborated. The panel met for consensus, with a threshold established for 2/3 of the participants. Results and Conclusions The treatment of advanced prostate cancer is complex, due to the existence of a large number of therapies, with different response profiles and toxicities. The panel addressed recommendations on preferred choice of therapies, indicators that would justify their change, and indicated some strategies for better sequencing of treatment in order to maximize the potential for disease control with the available therapeutic arsenal. The lack of consensus on some topics clearly indicates the absence of strong evidence for some decisions.

O ácaro-da-leprose, Brevipalpus phoenicis (Geijskes), é uma das principais pragas da cultura dos citros (Citrus spp.), por ser o transmissor do vírus que causa a leprose dos citros. O acaricida hexythiazox tem sido bastante utilizado no controle de B. phoenicis em pomares de citros. A resistência do ácaro a hexythiazox já foi detectada em altas freqüências em algumas localidades. Para a implementação de um programa de manejo da resistência, foram realizados estudos para entender a estabilidade da resistência de B. phoenicis a hexythiazox mediante 1) a comparação da biologia das linhagens suscetível (S) e resistente (R) ao hexythiazox em condições de laboratório e 2) a avaliação da dinâmica da resistência a hexythiazox em talhões de citros com baixa (< 20%) e alta (> 60%) freqüência de resistência, por dois anos. Estimativas da freqüência de resistência foram realizadas com bioensaio de contato direto sobre ovos, utilizando-se a concentração discriminatória de 18 mg de hexythiazox/L de água. Não foram verificadas diferenças significativas entre as linhagens S e R, quanto aos parâmetros biológicos avaliados para a confecção das tabelas de vida de fertilidade. No entanto, a resistência de B. phoenicis a hexythiazox foi instável em condições de campo, isto é, foram verificadas reduções significativas na freqüência de resistência na ausência de pressão de seleção, tanto em talhões de citros com baixa freqüência como em talhões com alta freqüência de resistência. Portanto, a instabilidade da resistência de B. phoenicis a hexythiazox pode ser explorada em programas de manejo da resistência.

The false spider mite, Brevipalpus phoenicis (Geijskes), is one the most important pests of the citrus groves and transmits the citrus leprosis virus. The acaricide hexythiazox has been widely used for controlling B. phoenicis in citrus groves. The resistance of this species to hexythiazox has already been detected at high frequencies at some locations. In order to implement a resistance management program, studies were undertaken to understand the stability of the resistance of B. phoenicis to hexythiazox by 1) comparing the life-history of susceptible (S) and resistant (R) strains under laboratory conditions, and 2) evaluating the dynamics of hexythiazox resistance in citrus field plots with low (< 20%) and high (> 60%) frequency of resistance, during two years. The frequencies of resistance were estimated with direct contact bioassays on eggs with discriminating concentration of 18 mg of hexythiazox/L of water. There were no significant differences between S and R strains, based on biological parameters evaluated to build fertility life tables. However, the resistance of B. phoenicis to hexythiazox was unstable under field conditions; that is, significant reductions in the frequency of resistance were observed in the absence of selection pressure, either in citrus field plots with low or high frequency of resistance. Therefore, the instability of B. phoenicis resistance to hexythiazox can be exploited in resistance management programs.

INTRODUÇÃO: Em nosso meio, os carcinomas gástricos ainda são neoplasias bastante freqüentes e responsáveis por altas taxas de mortalidade. Recentemente, têm-se demonstrado a expressão de p53 e a amplificação do gene c-erb-B2 nos carcinomas gástricos. A relevância e o significado biológico destas alterações ainda não foram totalmente estabelecidos. OBJETIVO: Estudar as expressões imuno-histoquímicas de p53 e c-erb-B2 em 482 casos de carcinomas gástricos. MATERIAL E MÉTODOS: Foram construídos três blocos de tissue microarray (TMA) utilizando-se duplicatas de 482 casos de carcinomas gástricos. Os cortes foram corados por hematoxilina e eosina (HE), tendo sido feita pesquisa para p53 e c-erb-B2. Foram considerados positivos para p53 os casos com marcação nuclear em mais de 10% das células tumorais. Para o c-erb-B2 foram considerados positivos os casos com marcação de membrana completa em mais de 10% das células tumorais. RESULTADOS: A expressão de p53 e c-erb-B2 foi observada em 30% e 12% dos casos, respectivamente. Em relação aos tipos histológicos observou-se correlação entre os carcinomas do tipo intestinal e a expressão de c-erb-B2 (p < 0,001). A expressão de p53 foi mais freqüente nos carcinomas com mais de 5cm de diâmetro (p = 0,036). Não foram observadas alterações nas curvas de sobrevida dos pacientes em relação às expressões desses marcadores. CONCLUSÃO: Em nosso meio, carcinomas gástricos do tipo intestinal são mais freqüentemente positivos para c-erb-B2 nos tipos intestinais do que nos difusos. A expressão de p53 está associada ao tamanho tumoral. A técnica do TMA é válida e eficiente para o estudo de marcadores imuno-histoquímicos, com forte correlação com os cortes tradicionais de representação do tumor.

INTRODUCTION: Gastric cancer is one of the commonest cancers in our country being responsible for a high mortality rate. Recently, the expression of p53 and amplification of c-erb-B2 gene have been described in gastric carcinoma. The relevance and biological significance of these findings are not established yet. OBJECTIVE: The authors investigated p53, c-erb-B2 immunohistochemical expression in 482 cases of gastric carcinomas. MATERIAL AND METHODS: Tissue microarray (TMA) blocks were designed using replicate samples of paraffin-embedded tissue from 482 gastric carcinomas. Sections were stained with HE, and antibodies to p53 and c-erb-B2. Cases were considered p53 positive if nuclear staining was detected in > 10% of the tumor cells. Cases were assessed c-erb-B2 positive if the entire circunference of the cell membrane was stained in > 10% of the tumor cells. RESULTS: Overall expression of p53 and c-erb-B2 was observed in 30% and 12% of gastric carcinomas cases, respectively. Relationship with intestinal type of gastric carcinomas and expression of c-erb-B2 was shown (p < 0.001), and expression of p53 was observed in tumors larger than 5cm (p = 0.003). There was not significant difference in survival curves of patients with gastric cancer in relation to the expression of these markers. CONCLUSION: Intestinal type of gastric carcinomas in our country are more frequently positive for c-erb-B2 than diffuse type. The expression of p53 is associated with tumor size. The TMA is a valid and efficient way to study immunohistochemical markers, having a high correlation with the full section.

OBJECTIVE: The biventricular pacing (BVP) approach has good results in the treatment of congestive heart failure (CHF) in patients (pts) with disorders of intraventricular conduction. METHODS: We have applied BVP to 28 pts, with left ventricular pacing using minitoracotomy in 3 pts and the transvenous aproach via coronary sinus in 25 pts. The mean duration of the QRS complexes was 187 ms, in the presence of the left branch block in 22 pts, and right branch block + divisional hemiblock in 6 pts. All pts had been considerated candidates to cardiac transplantation, and were under optimized drug therapy. Sixteen pts were in Functional Class (NYHA) IV, and 12 in class III. The ejection fraction varied from 22 to 46% (average = 34%). The pacing mode employed was biventricular triple-chamber in 22 pts, and bi-ventricular dual-chamber in 6 pts (one with ICD). RESULTS: The pts were followed up for a period that ranged from 10 days to 14 months (mean 5 months). All pts presented clinical improvement after implant, chaging the NYHA Functional Class at the end of follow-up to Class I (9pts), Class II (10 pts) and Class III (6 pts). The initial mean ejection fraction have-raised to 37%. Two pts died suddenly. One patient died due to a pulmonary fungal infection. CONCLUSION: Ventricular resynchronization through BVP, improved significantly the Functional Class and, therefore, the quality of life. Assessments of myocardial function acutely performed do not reflect the clinical improvement observed.
