This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.nbsp; Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities. nbsp; Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.nbsp; The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.nbsp; The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.nbsp; nbsp;nbsp; Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.

Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou. A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica. Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas. A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica. A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.nbsp;nbsp;nbsp; Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.nbsp;

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

Objective: To evaluate body dissatisfaction and distorted body self-image in women with prolactinoma. Methods: Body dissatisfaction and distorted body self-image were evaluated in 80 women with prolactinoma. All patients were in menacme, 34% had normal body mass index (BMI), and 66% were overweight. Most patients (56.2%) had normal prolactin (PRL) levels and no hyperprolactinemia symptoms (52.5%). The Body Shape Questionnaire (BSQ) was used to assess the patients’ dissatisfaction with and concern about their physical form, and the Stunkard Figure Rating Scale (FRS) was used to assess body dissatisfaction and distorted body self-image. The patients were divided according to PRL level (normal vs. elevated) and the presence or absence of prolactinoma symptoms. Results: The normal and elevated PRL groups had similar incidences of body dissatisfaction and distorted body self-image. However, symptomatic patients reported a higher incidence of dissatisfaction than asymptomatic patients. Distorted body self-image was less common among symptomatic patients. Conclusion: Symptomatic patients showed higher body dissatisfaction, but lower body self-image distortion. The presence of symptoms may have been responsible for increased body awareness. The perception of body shape could have triggered feelings of dissatisfaction compared to an ideal lean body. Therefore, a distorted body self-image might not necessarily result in body dissatisfaction in women with prolactinomas.

ABSTRACT Chemical investigation of the aqueous fraction of the ethanol extract from the Brazilian endemic marine sponge Clathria (Clathria) nicoleae Vieira de Barros, Santos & Pinheiro, 2013, Microcionidae, sampled from a 55 m deep rhodolith bed at the Amazon River mouth, led to the isolation of a new hexapeptide, clathriamide (1). HP-20 resin was used to capture compound 1 from the aqueous fraction, which was purified by additional chromatographic steps. The absolute configuration of the amino acids of 1 was determined by advanced Marfey's analysis using 5-fluoro-2,4-dinitrophenyl-Nα-L-tryptophanamide. The amino acid derivatives analyzed by ultra-performance liquid chromatography coupled to a mass spectrometry using a C8 column enabled a good chromatographic resolution of L-Ile and L-allo-Ile, previously unfeasible using C18 column.

ABSTRACT Graviola leaves (Annona muricata L., Annonaceae) are used by some people to try to treat or even cure cancer, even though over-consumption of the fruit, which contains the neurotoxins annonacin and squamocin has caused an atypical form of Parkinson's disease. In previous analyses, the fruits were extracted with methanol under ambient conditions before analyses. In the present study, UPLC–QTOF–MS and NMR were used to analyze freeze-dried graviola leaves that were extracted using dry methanol and ethanol at 100 ºC and 10 MPa (100 atm) pressure in a sealed container. Methanol solubilized 33% of the metabolites in the lyophilized leaves. Ethanol solubilized 41% of metabolites in the lyophilized leaves. The concentrations of total phenolic compounds were 100.3 ± 2.8 and 93.2 ± 2.0 mg gallic acid equivalents per g of sample, for the methanolic and ethanolic extracts, respectively. Moreover, the toxicophore (unsaturated γ-lactone) that is present in neurotoxic acetogenins was found in the lipophilic portion of this extract. The concentrations of the neurotoxins annonacin and squamocin were found by UPLC–QTOF–MS to be 305.6 ± 28.3 and 17.4 ± 0.89 µg/g-dw, respectively, in the dried leaves. Pressurized methanol solubilized more annonacin and squamocin than ethanol. On the other hand, a hot, aqueous infusion solubilized only 0.213% of the annonacin and too little of the squamocin to be detected. So, graviola leaves contain significant amounts of the neurotoxins annonacin and squamocin, as well as some potentially healthy phenolic compounds. Finally, the potential neurotoxicity of whole leaves in dietary supplements could be much higher than that of a tea (hot aqueous infusion) that is made from them.

ABSTRACT In no-tillage (NT) systems, there is no plowed layer since the soil is not tilled. Thus, the soil layer for fertility evaluation can be defined as the one in which the fertility indices are affected by the surface application of lime and fertilizers and soil properties have the closest relationship with crop yields. The objective of this study was to determine the most appropriate soil layer under long-term NT for sampling for fertility evaluation in the South-Central region of Paraná, Brazil. A total of 99 field experiments of crop rotations were performed, including soybean, corn, barley, wheat, and white oat, all on Oxisols (Hapludox). Despite the surface application, lime and fertilizers increased base saturation (V) and available K to a depth of 0.20 m. The relationship with crop yields was high for V and low for available K for both soil layers (0.00-0.10 and 0.00-0.20 m); for P, however, the relationships with soybean and corn yields were strongest in the 0.00-0.20 m layer. Thus, considering the soil layer fertilized by the surface application of lime and potassium fertilizers and the highest relationship of soil P contents with the yield of the main crops of the crop rotation, the 0.00-0.20 m layer is the most appropriate for soil fertility evaluation under long-term no-tillage systems.

Objective: To describe the anthropometric and physical fitness profiles of elite soccer players acting in the United Arab Emirates. Method: Twenty seven elite soccer players acting in the United Arab Emirates were underwent to an anthropometric evaluation, an incremental test in treadmill and performed the Running-Based Anaerobic Test (RAST). Results: Body mass index and body fat percentage of the athletes were 23. 1 ± 2. 0 kg. m-2 11. 6 ± 2. 1 %, respectively. Indirect maximum oxygen uptake (VO2max) was 62. 3 ± 5. 1 ml. kg-1. min-1, mean velocity at VO2max was 17. 6 ± 1. 5 km. h-1, ventilatory threshold (VT) of 13. 8 ± 0. 8 km. h-1, heart rate at VT of 173. 1 ± 8. 6 b. min-1, which represents of 91. 2 ± 2. 8 % of maximum heart rate. RAST resulted in a maximum absolute power of 551. 9 ± 73. 0 W, maximum relative power of 7. 8 ± 0. 4 W. kg-1, mean absolute power of 484. 0 ± 57. 8 W, and mean relative power of 6. 8 ± 0. 2 W. kg-1. Conclusion: The anthropometric profile of soccer players that act in the United Arab Emirates is similar to others around the world. However, regarding the physical fitness, results are still inconclusive, since findings from other studies suggest that the anaerobic power of our sample is alike or lower than other elite players throughout the world. Likewise indirect VO2max, especially given the acknowledged limitations of obtaining indirectly this variable. In addition, making an analysis by playing position, the results of this study are similar to previous research.

Objetivo: Describir el perfil antropométrico y la aptitud física de los jugadores de fútbol de élite que trabajan en los Emiratos Árabes Unidos. Métodos: Veintisiete jugadores de fútbol de élite que trabajan en los Emiratos Árabes Unidos fueron sometidos a una evaluación antropométrica, un test incremental en un tapiz rodante y Running-Based Anaerobic Test (RAST). Resultados: El índice de masa corporal y el porcentaje de grasa fueron 23,1 ± 2,0 kg. m-2 y 11,6 ± 2,1 %, respectivamente. El consumo máximo de oxígeno (VO2máx) estimado fue 62,3 ± 5,1 ml. kg-1. min-1, y la velocidad media de VO2máx fue 17,6 ± 1,5 km. h-1, y la velocidad media de umbral ventilatorio (UV) fue 13,8 ± 0,8 km. h-1. La frecuencia cardíaca del UV fue en media 173,1 ± 8,6 b. min-1, lo que representa 91,2 ± 2,8 % de la frecuencia cardíaca máxima. El test RAST resultó en una potencia máxima absoluta de 551,9 ± 73,0 W, potencia máxima relativa de 7,8 ± 0,4 W. kg-1, potencia media absoluta de 484,0 ± 7,8 W, y potencia media relativa de 6,8 ± 0,2 W. kg-1. Conclusión: El perfil antropométrico de los jugadores de fútbol que trabajan en los Emiratos árabes Unidos es similar a otros del resto del mundo. Sin embargo, en cuanto a la aptitud física, los resultados aún no son concluyentes, porque los resultados de otros estudios sugieren que la potencia anaerobia de nuestra muestra es igual o inferior a la de otros jugadores de élite de todo el mundo. Del mismo modo, el VO2max indirecto no es concluyente, teniendo en cuenta las limitaciones reconocidas de obtener indirectamente esta variable. Finalmente, al analizar los jugadores de acuerdo con a la posición táctica, los resultados de este estudio son similares a los estudios anteriores.

A adoção do plantio direto (PD) em substituição ao preparo convencional promove alterações na dinâmica de nutrientes e na acidez no solo, podendo influenciar as relações solo-planta e, portanto, os critérios de manejo da fertilidade do solo. Este estudo teve como objetivo determinar os critérios de recomendação de calagem e os teores críticos de fósforo (P) e potássio (K) para o sistema de rotação de culturas envolvendo soja, milho, trigo, cevada e aveia branca, amplamente adotado na região Centro-Sul do Paraná. O estudo foi com base em 13 experimentos de campo conduzidos em Latossolos Brunos em longo prazo em PD (>15 anos), nos municípios de Guarapuava, Pinhão e Candói. Desses, cinco envolveram calagem e oito adubação de P e K. Em amostras de solo das camadas de 0-0,10 e 0,10-0,20 m, foi determinado o pH (CaCl2) e calculada a saturação por bases (V%) nos experimentos de calagem e os teores de P e K disponível (Mehlich-1) nos experimentos de adubação. O método dos quadrantes foi utilizado para determinar os critérios de recomendação de calagem; e o nível crítico de pH e V% consistiu no valor em que, acima do qual, as culturas apresentaram rendimento relativo (RR) superior a 90 % e nunca inferior a 80 %. A relação entre os teores de P e K e os valores de RR foi verificada pela equação de Mitscherlich, sendo o teor crítico aquele correspondente ao RR de 90 %. Os resultados indicaram que os níveis críticos relacionados à acidez e disponibilidade de P e K foram maiores para a camada de 0-0,10 m do que para a de 0-0,20 m. A cultura da soja foi mais sensível à acidez do solo, enquanto os cereais de inverno foram mais exigentes em P e K. Tomando-se como referência as culturas mais restritivas do sistema de rotação e a camada de 0-0,20 m, os níveis críticos para calagem foram pH (CaCl2) de 4,9 e saturação por bases de 60 %, enquanto os teores críticos para adubação foram 8 mg dm-3 de P e 0,30 cmol c dm-3 de K para Latossolos cultivados no longo prazo em sistema PD na região Centro-Sul do Paraná.

When conventional tillage is replaced by no-tillage (NT) changes occur in the dynamics of soil nutrients and acidity, which may influence the soil-plant relationships and consequently, the criteria for soil fertility management. This study determined the criteria for liming as well as the soil critical levels for P and K in a crop rotation of soybean, maize, wheat, barley, and white oat, widely used in the South-Central region of the State of Parana, in Southern Brazil. The study involved 13 field experiments on Hapludox soils under long-term no-tillage (>15 years) in Guarapuava, Pinhão and Candói; five of the experiments were related to liming and eight to P and K fertilization. In soil samples from the layers 0-0.10 and 0.10-0.20 m, of the liming studies, CaCl2-pH and base saturation (V%) were quantified and available P and K (Mehlich-1) in the samples from the fertilization. The quadrant method was used to determine the liming criteria; the critical levels for pH and base saturation were based on values that ensured relative crop yields above 90 % and never below 80 %. The ratio between the soil P and K levels and the relative crop yields could be represented by the Mitscherlich equation, where the levels required for relative crop yields of 90 % represent the critical values. The results indicated that the critical levels of soil acidity and available P and K were higher in the 0-0.10 m than the 0-0.20 m layer. Soybean was most sensitive to soil acidity, while the winter cereals were most demanding in P and K. Based on the most restrictive crop in the rotation and 0-0.20 m soil layer as reference, the critical levels for liming were CaCl2-pH of 4.9 and base saturation of 60 %, while the critical levels of fertilization were 8.0 mg dm-3 for P and 0.30 cmol c dm-3 for K for Oxisoils under long-term no-tillage, in the South-Central Region of Paraná.

Apresentamos dados clínicos e moleculares de quatro famílias com adenoma hipofisário familiar isolado (FIPA) enfatizando as diferenças na presença ou não de mutação do AIP e a importância da triagem genética. A Família 1 é composta por cinco pacientes portadores de somatotropinomas com mutação germinativa E24X no AIP. Um dos pacientes foi diagnosticado por meio de rastreio ativo, com cura cirúrgica. As Famílias 2 e 3 apresentam em sua composição dois pacientes com adenomas hipofisários não funcionantes. A Família 4 compreende dois pacientes, um com prolactinoma e outro com somatotropinoma. Não foi encontrada mutação no AIP nessas famílias. Na Família 1, não houve resposta ao octreotide, enquanto o paciente acromegálico da Família 4 foi controlado com a medicação. Em conclusão, a FIPA é uma condição heterogênea que pode estar associada à mutação do AIP e o rastreio genético/clínico é recomendado nas famílias com dois ou mais membros portadores de adenoma hipofisário. Isso permite um diagnóstico precoce, com melhor prognóstico.

We present four FIPA kindred discussing clinical and molecular data and emphasizing the differences regarding AIP status, as well as the importance of genetic screening. Family 1 consists of five patients harboring somatotropinomas with germline E24X mutation in AIP. In one of the patients, acromegaly was diagnosed through active screening, being cured by surgery. Families 2 and 3 are composed of two patients with non-functioning pituitary adenomas. Family 4 comprises patients harboring a prolactinoma and a somatotropinoma. No mutations in AIP were found in these families. No patient in Family 1 was controlled with octreotide treatment, while the acromegalic patient in Family 4 was controlled with octreotide LAR. In conclusion, FIPA is a heterogeneous condition, which may be associated with AIP mutation. Genomic and clinical screening is recommended in families with two or more members harboring pituitary adenomas, allowing early diagnosis and better outcome.

Resumo: En | Texto: En | PDF: En

Susceptibility to experimental autoimmune uveitis (EAU) in inbred mice has been associated with a dominant Th1 response. Elevated anti-inter-photoreceptor retinoid-binding protein (anti-IRBP) IgG2a/IgG1 antibody ratios have been implicated as candidate markers to predict disease severity. In the present study, both the anti-IRBP antibody isotype and severity of EAU phenotypes were examined in 4 non-isogenic genetically selected mouse lines to determine if they can be used as general markers of disease. Mice between 8 and 12 weeks old selected for high (H III) or low (L III) antibody response and for maximum (AIR MAX) or minimum (AIR MIN) acute inflammatory reaction (AIR) were immunized with IRBP. Each experiment was performed with at least 5 mice per group. EAU was evaluated by histopathology 21 days after immunization and the minimal criterion was inflammatory cell infiltration of the ciliary body, choroid and retina. Serum IgG1- and IgG2a-specific antibodies were determined by ELISA. EAU was graded by histological examination of the enucleated eyes. The incidence of EAU was lower in AIR MIN mice whereas in the other strains approximately 40% of the animals developed the disease. Low responder animals did not produce anti-IRBP IgG2a antibodies or interferon-gamma. No correlation was observed between susceptibility to EAU and anti-IRBP isotype profiles. Susceptibility to EAU is related to the intrinsic capacity to mount higher inflammatory reactions and increased production of anti-IRBP IgG2a isotype is not necessarily a marker of this immunologic profile.
