Abstract: En Pt

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 Background Stroke is one of the most common causes of death and incapacity in the world. The benefits of reperfusion therapies and hospitalization in neurologic intensive care units (ICUs) are undeniable. However, these treatments are not widely available in a continental-sized country like Brazil. Objective To describe the treatment for ischemic stroke and the functional outcome 90 days after the hospitalization of patients in the Brazilian countryside. Methods Observational, prospective case series study design. The data collected refer to randomly selected patients hospitalized in 3 hospitals in the south region of the state of Bahia between December 2018 and December 2019. Results The population consisted of 61 consecutive patients. They were elderly (median age: 62 years old); with a predominance of hypertension (82%); and were light to moderate stroke cases (National Institute of Health Stroke Scale [NIHSS] median: 7). A total of 37.7% of the cases arrived at the hospital in a < 4.5-hour window but received no reperfusion therapy. Of these, 94.3% were discharged from the hospital with a prescription for antiplatelets or anticoagulant. A total of 64.1% of the patients received a statin prescription. At the end of the follow-up period, the general mortality was 21%. Almost half of the population (47.9%) evolved to an unfavored outcome (modified Rankin scale [mRs]: 3 to 6). Conclusion Our population presented sociodemographic and comorbidities characteristics similar to those of other national samples. No reperfusion therapy was used and the treatment was basically secondary and prophylaxis-oriented, and almost half of the population evolved with incapacities and a high mortality rate, despite the initial low clinical gravity.

Resumo Antecedentes Acidente vascular cerebral (AVC) é uma das principais causas de morte e incapacidade no mundo. Os benefícios das terapias de reperfusão e hospitalização em unidade intensiva neurológica são inegáveis. Porém, estes tratamentos não estão largamente disponíveis em um país de dimensões continentais como o Brasil. Objetivos Descrever o tratamento do AVC isquêmico agudo e a funcionalidade, 90 dias após o evento, de pacientes hospitalizados no interior do Brasil. Métodos Estudo observacional, prospectivo, tipo série de casos. Os dados foram coletados de pacientes consecutivos, aleatoriamente selecionados, internados em 3 hospitais da região Sul da Bahia entre dezembro de 2018 e dezembro de 2019. Resultados A população amostral consistiu de 61 pacientes. Houve predomínio de idosos (mediana de idade: 62 anos), hipertensos (82%), com AVC leve a moderado (mediana do National Institute ok Health Stroke Scale [NIHSS, na sigla em inglês]: 7), dos quais 37,7% chegaram ao hospital com < 4,5 horas de sintomas, mas não receberam terapias de reperfusão. Um total de 94,3% dos pacientes recebeu alta com prescrição de antiagregante plaquetário ou anticoagulante e 64,1% receberam prescrição de estatina. Ao final do período de seguimento, a mortalidade geral foi de 21% e quase metade da população amostral (47,9%) evoluiu com desfecho desfavorável (escala de Rankin modificada: 3 a 6). Conclusão A população amostral apresentou características sociodemográficas e comorbidades semelhantes às de outros recortes nacionais. Terapias de reperfusão não foram realizadas e o tratamento foi basicamente orientado para profilaxia secundária. Quase metade da população evoluiu com incapacidade ou morte, apesar da baixa gravidade clínica à admissão.

Resumen Introducción. La ingesta de cepillos de dientes, voluntaria o accidental, es una situación poco frecuente que requiere ser tratada como una emergencia, pues por su longitud y dureza, no se espera que estos cuerpos extraños tengan un tránsito completo por el tracto digestivo, lo que puede causar graves complicaciones. Presentación del caso. Mujer de 22 años con trastorno alimentario (bulimia nerviosa) quien al inducirse vomito ingirió involuntariamente un cepillo de dientes. Lamentablemente, después de la valoración inicial en el servicio de urgencias, debido a que no presentaba síntomas, a su antecedente psiquiátrico y a la no identificación del cepillo en estudios de imagen, fue dada de alta. Ante la insistencia de la paciente de decir la verdad, fue remitida por su médico tratante a una institución de salud de segundo nivel, donde, a las 36 horas de la ingesta, se realizó la extracción endoscópica exitosa del cepillo. El procedimiento fue realizado bajo sedación por expertos en extracción digestiva usando un sobretubo, pinzas para cuerpos extraños y asas de polipectomía. Conclusión. Los casos de ingesta de cepillos de dientes son raramente reportados y ocurren principalmente en personas con trastornos psiquiátricos como desórdenes alimentarios que involucran la inducción de vómito. Por tanto, en estos casos siempre se debe creer la versión del paciente, incluso en ausencia de síntomas y hallazgos imagenológicos, pues esto posibilita una remisión oportuna al servicio digestivo para confirmar la ingesta y realizar la extracción endoscópica lo más pronto posible, ya que, por sus características, pueden causar graves complicaciones.

Abstract Introduction: Toothbrush swallowing, whether voluntary or accidental, is a rare event and must be handled as an emergency, because these foreign bodies, due to their length and hardness, are not expected to pass completely through the digestive tract and may cause serious complications. Case presentation: A 22-year-old woman with an eating disorder (bulimia nervosa) involuntarily swallowed a toothbrush while inducing vomiting. Unfortunately, after the initial assessment in the emergency department, and due to the lack of symptoms, her psychiatric history, and the fact the toothbrush was not observed in imaging studies, she was discharged. Due to the patient's insistence that she was telling the truth, she was referred to a secondary healthcare institution by her treating physician, where the successful endoscopic extraction of the toothbrush was performed 36 hours after it was swallowed. The procedure was carried out with the patient under sedation and by experts in digestive extraction who used an overtube, foreign body forceps, and polypectomy loops. Conclusion: Cases of toothbrush swallowing are rarely reported and occur mainly in people with mental illnesses, such as eating disorders involving self-induced vomiting. Therefore, in these cases, physicians should always believe what these patients say, even in the absence of symptoms and imaging findings, as this enables their timely referral to a digestive service to confirm whether the toothbrush was swallowed or not and to perform the endoscopic extraction as soon as possible, since it can cause serious complications due to its characteristics.

ABSTRACT The objective of this work was to quantify damage and yield losses in lettuce parasitized by Meloidogyne javanica, as well as the growth characteristics of naturally cultivated field plants infested by this pathogen. The experimental area consisted of four seedbeds of 10.0x1.60 m cultivated with 160 plants in each, totaling 640 plants. The damages and yield loss were quantified in four evaluations (Ev1, Ev2, Ev3, and Ev4), with each evaluation corresponding to a cultivation cycle. The four plantings were made in the consecutive form. The fresh mass weight and dry mass weight (FMW and DMW, respectively), gall number (GN), and final population of the nematodes (FP) were evaluated. The population increase of M. javanica caused a reduction in the FMW and DMW in all evaluations. In Ev1 and Ev2, 100% of the plants were commercialized. In Ev3 and Ev4, 7% and 65% of the plants, respectively, could not be commercialized. The Ev4 was completely unviable since the produce had losses of U$ 7.42; U$ 23.19 and U$ 1,484.10 for the cultivation of 640; 2,000 and 128,000 plants, respectively. The economic threshold in Ev4 was 10,151 nematodes/plant or 109 galls/plant.

RESUMEN El objetivo de este trabajo fue cuantificar el daño agronómico en un cultivo de lechugas parasitadas por Meloidogyne javanica y caracterizar el crecimiento de plantas cultivadas en un campo infestado por este patógeno. El estudio se hizo en cuatro camas de 10.0 x 1.60 m cultivadas con 160 plantas en cada una, totalizando 640 plantas por cada ciclo de cultivo. Se hicieron cuatro tratamientos (Ev1, Ev2, Ev3 y Ev4), correspondientes a un ciclo de cultivo. Las cuatro plantaciones se realizaron de forma consecutiva y se seleccionaron 100 plantas al azar para cuantificar el efecto del nematodo en las lechugas. Los parámetros evaluados fueron peso fresco (PMF), peso seco (PMS), número de agallas (NG) y la población final de nematodos (PF). El aumento de la población de M. javanica provocó una reducción de PMF y PMS en todas las evaluaciones. En Ev1 y Ev2 se vendió el 100% de las plantas. En Ev3 y Ev4 hubo un 7% y un 65% de las plantas, respectivamente, que no pudieron venderse. El cuarto ciclo de cultivo (Ev4) resultó completamente inviable, ya que las pérdidas fueron de U $ 7,42; U $ 23,19 y U $ 1.484,10 para el cultivo de 640, 2.000 y 128.000 plantas, respectivamente. El umbral económico en Ev4 fue de 10.151 nematodos /planta o 109 agallas /planta.

Abstract Background: The resistance against antimalarial drugs represents a global challenge in the fight and control of malaria. The Brazilian biodiversity can be an important tool for research and development of new medicinal products. In this context, toxinology is a multidisciplinary approach on the development of new drugs, including the isolation, purification, and evaluation of the pharmacological activities of natural toxins. The present study aimed to evaluate the cytotoxicity, as well as the antimalarial activity in silico and in vitro of four compounds isolated from Rhinella marina venom as potential oral drug prototypes. Methods: Four compounds were challenged against 35 target proteins from P. falciparum and screened to evaluate their physicochemical properties using docking assay in Brazilian Malaria Molecular Targets (BraMMT) software and in silico assay in OCTOPUS® software. The in vitro antimalarial activity of the compounds against the 3D7 Plasmodium falciparum clones were assessed using the SYBR Green I based assay (IC50). For the cytotoxic tests, the LD50 was determined in human pulmonary fibroblast cell line using the [3(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) assay. Results: All compounds presented a ligand-receptor interaction with ten Plasmodium falciparum-related protein targets, as well as antimalarial activity against chloroquine resistant strain (IC50 = 3.44 μM to 19.11 μM). Three of them (dehydrobufotenine, marinobufagin, and bufalin) showed adequate conditions for oral drug prototypes, with satisfactory prediction of absorption, permeability, and absence of toxicity. In the cell viability assay, only dehydrobufotenin was selective for the parasite. Conclusions: Dehydrobufotenin revealed to be a potential oral drug prototype presenting adequate antimalarial activity and absence of cytotoxicity, therefore should be subjected to further studies.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Abstract Fungi are excellent producers of extracellular enzymes. Therefore, the present study aimed to investigate the screening of marine fungi, which are laccase and manganese peroxidase potential producers, in solid fermentation for future applications in bioremediation processes of contaminated sites. For this purpose, two-level factorial planning was adopted, using time (6 and 15 days) and the absence or presence of oil (0 and 1%) as factors. The semi-quantitative evaluation was carried out by calculating radial growth, enzyme activity and enzyme index by measuring phenol red or syringaldazine oxidation halo. The results showed that all the studied strains showed a positive result for manganese peroxidase production, with an enzymatic activity in solid medium less than 0.61, indicating a strongly positive activity. Through the enzyme index, the study also showed prominence for Penicillium sp. strains, with values > 2. The enzyme index increase in oil presence and the inexpressive use of the genera studied for ligninolytic enzymes production from crude oil demonstrated these data importance for fermentative processes optimization. Considering the ability of these strains to develop into recalcitrant compounds and the potential for manganese peroxidase production, they are indicated for exploitation in various bioremediation technologies, as well as other biotechnological applications.

Abstract Dimethylacetamide has been included in different extenders for the cryopreservation of semen from species with promising results. The objective of this study was to evaluate the use of dimethylacetamide (DMA) in different concentrations, associated or not with glycerol (GLY), for the cryopreservation of ovine semen, and its effects on in vitro sperm parameters and post-thaw in vivo fertility. Five semen samples of five adult Santa Ines sheep (n=25) were used. The collected ejaculates were divided among the seven treatments for subsequent cryopreservation. The treatments presented different concentrations of DMA and GLY, being divided as G1: GLY 6%; G2: DMA 3%; G3: GLY 5% + DMA 1%; G4: GLY 4% + DMA 2%; G5: GLY 3% + DMA 3%; G6: GLY 2% + DMA 4%; G7: GLY 1% + DMA 5%. %. Post-thawing of the straws, aliquots were evaluated for computerized sperm kinetics (CASA) and plasma membrane integrity, using fluorescent probes and flow cytometry. After the in vitro evaluation of the sperm parameters, in vivo testing was performed by laparoscopic artificial insemination of 72 females. The post-thaw total motility (%) evaluated by CASA were 51.4, 51.4, 50.1, 53.6, 52.3, 52.8 and 46.9, respectively, for the seven groups. And the plasma membrane integrity (%) were 19.7, 28.4, 22.3, 29.4, 24.3, 17.9 and 16.9, respectively. There were no differences (P> 0.05) between the treatments for the parameters of spermatic kinetics and membrane integrity. For females inseminated with semen from the control group (G1, GLY6%), the percentage of pregnant females was 36.1%, a result similar to that obtained with G3 treatment (GLY5% + DMA1%). In conclusion, dimethylacetamide, either alone or in combination with glycerol, can be used for cryopreservation of ovine semen.

RESUMO Racional: Carcinoma incidental da vesícula biliar é definido como uma neoplasia descoberta por exame histológico após colecistectomia videolaparoscópica. É potencialmente uma doença curável. Entretanto algumas questões relacionadas ao seu manuseio permanecem controversas e uma estratégia definida está associada com melhor prognóstico. Objetivo: Desenvolver o primeiro consenso baseado em evidências para o manuseio de pacientes com carcinoma incidental da vesícula biliar no Brasil. Métodos: Dezesseis questões foram selecionadas e para responder as questões e 36 membros das sociedades brasileiras e internacionais foram incluídos. As recomendações foram baseadas em evidências da literatura atual. Um relatório final foi enviado para os membros do painel para avaliação de concordância. Resultados: Avaliação intraoperatória da peça cirúrgica, uso de bolsas para retirar a peça cirúrgica e exame histopatológico de rotina, foram recomendados. Avaliação pré-operatória completa é necessária e deve ser realizada assim que o estadiamento final esteja disponível. Avaliação da margem do ducto cístico e biópsia de rotina do linfonodo 16b1 são recomendadas. Quimioterapia deve ser considerada e quimioradioterapia indicada se a margem cirúrgica microscópica seja positiva. Os portais devem ser ressecados excepcionalmente. O estadiamento laparoscópico antes da operação é recomendado, mas o tratamento radical por abordagem minimamente invasiva deve ser realizado apenas em centros especializados em cirurgia hepatopancreatobiliar minimamente invasiva. A extensão da ressecção hepática é aceitável até que seja alcançada a ressecção R0. A linfadenectomia padrão é indicada para tumores iguais ou superiores a T2, mas a ressecção da via biliar não é recomendada de rotina. Conclusões: Recomendações seguras foram preparadas para carcinoma incidental da vesícula biliar, destacando os mais frequentes tópicos do trabalho diário do cirurgião do aparelho digestivo e hepatopancreatobiliar.

ABSTRACT Background: Incidental gallbladder cancer is defined as a cancer discovered by histological examination after cholecystectomy. It is a potentially curable disease. However, some questions related to their management remain controversial and a defined strategy is associated with better prognosis. Aim: To develop the first evidence-based consensus for management of patients with incidental gallbladder cancer in Brazil. Methods: Sixteen questions were selected, and 36 Brazilian and International members were included to the answer them. The statements were based on current evident literature. The final report was sent to the members of the panel for agreement assessment. Results: Intraoperative evaluation of the specimen, use of retrieval bags and routine histopathology is recommended. Complete preoperative evaluation is necessary and the reoperation should be performed once final staging is available. Evaluation of the cystic duct margin and routine 16b1 lymph node biopsy is recommended. Chemotherapy should be considered and chemoradiation therapy if microscopically positive surgical margins. Port site should be resected exceptionally. Staging laparoscopy before reoperation is recommended, but minimally invasive radical approach only in specialized minimally invasive hepatopancreatobiliary centers. The extent of liver resection is acceptable if R0 resection is achieved. Standard lymph node dissection is required for T2 tumors and above, but common bile duct resection is not recommended routinely. Conclusions: It was possible to prepare safe recommendations as guidance for incidental gallbladder carcinoma, addressing the most frequent topics of everyday work of digestive and general surgeons.

RESUMO Este artigo apresenta uma discussão teórico-conceitual sobre as potencialidades da Atenção Primária à Saúde como estratégia imperativa à consolidação dos sistemas universais de saúde. Reflete a conjuntura atual do sistema de saúde brasileiro, expondo seus principais avanços no que diz respeito à garantia do direito à saúde e ao acesso aos serviços públicos de saúde e, ainda, seus desafios que perpassam problemas sociais e de saúde de natureza complexa, em um país marcado por grandes desigualdades sociais e econômicas entre as suas regiões, estados e municípios. Os sérios desafios contemporâneos à consolidação do Sistema Único de Saúde, para sua sustentação como política pública universal, envolvem a superação da hegemonia do modelo biomédico, a superação da política econômica neoliberal e a construção de uma condição plena de cidadania de forma que a população reconheça seus direitos fundamentais, incluindo o direito à saúde pública e de qualidade. Para o alcance de sistemas universais, é necessário incentivar um modelo de atenção à saúde que tenha na atenção primária e nas equipes de saúde da família estratégias de promoção da saúde da população e de fortalecimento da cidadania.

ABSTRACT This essay presents a theoretical-conceptual discussion about the potentialities of Primary Health Care as an imperative strategy for the development of universal health systems. It reflects the current scenario of the Brazilian health system, exposing its main advances regarding the guarantee of the right to health and access to public health services and, furthermore, its challenges that permeate social problems and health of a complex nature, in a country marked by great social and economic inequalities between its regions, states, and municipalities. The serious contemporary challenges for the development of the Unified Health System, for its sustainability as a universal public policy, involve overcoming the hegemony of the biomedical model, overcoming the neoliberal economic policy, and the construction a full citizenship condition so that the population recognizes their fundamental rights, including the right to a public health of quality. In order to achieve universal systems, it is necessary to promote a health care model that has in primary health care and family health care teams the necessary strategies for promoting health for the population and strengthening of citizenship.

Resumo O presente trabalho foi desenvolvido na zona costeira do estado de Pernambuco adjacente a área portuária do Recife, correspondente à plataforma. Apresentou como objetivo analisar a dinâmica da clorofila-a e variáveis ambientais. As coletas foram realizadas bimestralmente, na superfície, de maio/10 a setembro/11 englobando os períodos chuvoso e estiagem, durante a baixa-mar e em maré de sizígia. Os parâmetros analisados foram clorofila-a, salinidade, temperatura, transparência, oxigênio dissolvido, taxa de saturação do oxigênio, pH, material em suspensão e nutrientes inorgânicos dissolvidos. A biomassa fitoplanctônica variou entre 13,48 e 145,09 mg m-3 na área estuarina e na plataforma a variação foi de 0,24 a 19,29 mg m-3 no período de estiagem e 0,78 a 5,20 mg m-3 no período chuvoso. A ACP evidenciou uma relação direta da clorofila-a com N-amoniacal, fosfato e transparência e inversa com o material particulado em suspensão e nitrato. A biomassa não apresentou diferença significativa para sazonal e espacialidade. O estuário do rio Capibaribe é considerado altamente impactado, e ao formar a bacia portuária do Recife, este se soma a mais dois corpos d'água fortemente eutrofizados, o rio Beberibe e a Bacia do Pina, fazendo com que a influência na plataforma adjacente seja ampliada. Em termos de dispersão de pluma dos rios no porto do Recife, a presença do dique provoca uma certa perturbação no sentido da corrente, limitando esta pluma para a parte mais costeira e influencia as variáveis oceanográficas na plataforma interna.

Abstract This study was undertaken in the coastal zone of the state of Pernambuco adjacent to the Recife port area, which corresponds to the inner shelf. This research aimed to analyze the dynamics of chlorophyll-a and several other environmental variables. Sampling was undertaken bimonthly on the surface from September 11th to May 10th, thus including the rainy and dry periods, and during low tide in spring tide. The parameters analyzed were chlorophyll-a, salinity, temperature, transparency, dissolved oxygen, oxygen saturation rate, pH, suspended solids, dissolved inorganic nutrients. Phytoplankton biomass ranged from 13.48 to 145.09 mg m-3 in the estuarine area and on the inner shelf, the variation being from 0.24 to 19.29 mg m-3 in the dry season and from 0.78 to 5.20 mg m-3 in the rainy season. PCA showed a direct relationship of chlorophyll-a with ammonia, phosphate and transparency and an inverse relationship with suspended particulate matter and nitrate. Biomass did not vary significantly different as a result of seasonal or spatial dynamics. The estuary of the Capibaribe River is considered highly impacted, and as it forms the Recife port basin, it joins with two more strongly eutrophic water bodies, the Beberibe River and the Pina Basin, leading to an amplification of its influence on the adjacent shelf. In terms of the river plume's dispersion in the Port of Recife, the presence of a dike causes some disturbance in the direction of the current, limiting the plume to the area close to the coast and influences the oceanographic variables on the inner continental shelf.

RESUMO Conduzimos um estudo florístico em fragmentos de floresta nativa de uma área localizada entre o ParqueNacional do Iguaçu e a Área de Preservação Permanente do Lago de Itaipu, oeste do Estado do Paraná, objetivando ampliar o conhecimento florístico regional e compilar informações sobre as espécies para subsidiar projetos de restauração naquela área. Encontramos 204 espécies e 51 famílias, sendo as mais ricas Fabaceae (29 spp.), Myrtaceae (18 spp.), Solanaceae (10 spp.), Euphorbiaceae, Meliaceae e Rutaceae (nove spp. cada). A síndrome zoocórica foi a mais comum (69% das espécies), seguida pela anemocórica (17%) e autocórica (14%). As espécies não pioneiras foram as mais frequentes (64%). Qualitativamente, de modo geral, esses resultados coincidem com o observado em florestas estacionais semideciduais. Com base em dados fitossociológicos de outros estudos, indicamos 34 espécies localmente abundantes que podem ser usadas em maiores proporções em projetos de restauração. Registramos sete espécies ameaçadas de extinção e 15 exóticas, das quais 12 possuem potencial invasivo demandando ações de controle.

ABSTRACT Aiming to expand the regional floristic knowledge and compile species information to subsidize restoration projects, we conducted a floristic survey in native forest fragments of an area located between the Parque Nacionaldo Iguaçu and the Área de Preservação Permanente do Lago de Itaipu, in western Paraná State. We found 204 species and 51 families, being the richest Fabaceae (29 spp.), Myrtaceae (18 spp.), Solanaceae (10 spp.), Euphorbiaceae, Meliaceae and Rutaceae (nine spp. each). The zoochoric syndrome was the most common (69% of the species), followed by anemochoric (17%) and autochoric (14%). The non-pioneer species were the most frequent (64%). In general terms, these results agree qualitatively with those observed in seasonal semideciduous forests. Based on phytosociological data from other studies, we indicated 34 locally abundant species that can be used in greater proportions in restoration projects. We recorded seven species threatened and 15 exotic, of which 12 have invasive potential and require actions for controlling.
