ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT Objective: The purpose of these guidelines is to provide specific recommendations for the surgical treatment of neck metastases in patients with papillary, follicular, and medullary thyroid carcinomas. Materials and methods: Recommendations were developed based on research of scientific articles (preferentially meta-analyses) and guidelines issued by international medical specialty societies. The American College of Physicians’ Guideline Grading System was used to determine the levels of evidence and grades of recommendations. The following questions were answered: A) Is elective neck dissection indicated in the treatment of papillary, follicular, and medullary thyroid carcinoma? B) When should central, lateral, and modified radical neck dissection be performed? C) Could molecular tests guide the extent of the neck dissection? Results/conclusion: Recommendation 1: Elective central neck dissection is not indicated in patients with cN0 well-differentiated thyroid carcinoma or in those with noninvasive T1 and T2 tumors but may be considered in T3-T4 tumors or in the presence of metastases in the lateral neck compartments. Recommendation 2: Elective central neck dissection is recommended in medullary thyroid carcinoma. Recommendation 3: Selective neck dissection of levels II–V should be indicated to treat neck metastases in papillary thyroid cancer, an approach that decreases the risk of recurrence and mortality. Recommendation 4: Compartmental neck dissection is indicated in the treatment of lymph node recurrence after elective or therapeutic neck dissection; “berry node picking” is not recommended. Recommendation 5: There are currently no recommendations regarding the use of molecular tests in guiding the extent of neck dissection in thyroid cancer.

Background Eucalyptus is the primary cultivated wood species in Brazil, covering 7.5 million hectares. Weed competition in eucalyptus plantations reduces yield and increases operational costs. FuturaGene/Suzano has developed genetically modified (GM) eucalyptus varieties with glyphosate herbicide tolerance (HT) as a modern tool for improving weed management practices in plantations. The first event received regulatory approval for commercial deployment in 2021. However, the introgression of a new GM trait into eucalyptus, a non-isogenic species, cannot be achieved through selfing or backcrossing. To overcome this limitation and expedite the introgression of HT into the breeding population, multiple GM events were generated, in various genetic backgrounds and genomic locations, enabling simultaneous crossing with numerous elite parents. Objective To characterize the newly developed HT GM eucalyptus events and assess their safety for the environment and wood production. Methods HT GM eucalyptus events were subjected to genome sequencing and glyphosate tolerance testing. Biosafety analyses and environmental impact assessments were conducted through field trials in various eucalyptus cultivation regions, comparing the HT GM eucalyptus with conventional clones.

Resumo Objetivo: Mensurar os tempos de trânsito de contraste (TTCs) entre o sítio de injeção em veia antecubital e a veia cava superior, tronco arterial pulmonar e aorta ascendente em exames de tomografia computadorizada de artérias coronárias de pacientes sem história de doenças cardiovasculares ou pulmonares, definindo padrões de normalidade para esses tempos de circulação. Materiais e Métodos: Os TTCs entre o sítio de injeção e a veia cava superior, tronco arterial pulmonar e aorta ascendente foram medidos com base nas imagens de monitoração (bolus tracking). O débito cardíaco foi calculado com base nas imagens de angiotomografia computadorizada pelo método geométrico e correlacionado com os TTCs. Resultados: Foram analisados 43 pacientes. O TTC médio entre o tronco arterial pulmonar e a aorta ascendente foi de 7,2 s, entre a veia cava superior e o tronco arterial pulmonar foi de 3 s e entre a veia antecubital e a aorta ascendente foi de 13 s. Houve tendência a correlação entre o TTC e o débito cardíaco, com valor de p de 0,055. Conclusão: Os valores de normalidade do TTC entre a veia cava superior, tronco arterial pulmonar e aorta ascendente foram estabelecidos, servindo de base para avaliação clínica.
Abstract Objective: To measure the transit times (TTs) of contrast agents among the injection site (antecubital vein), superior vena cava, pulmonary trunk, and ascending aorta, in coronary computed tomography angiography (CTA) examinations of outpatients with no history of cardiovascular or lung disease, thus defining reference values for those TTs. Materials and Methods: The contrast TTs from the injection site (antecubital vein) to the superior vena cava, from the superior vena cava to the pulmonary trunk, and from the pulmonary trunk to the ascending aorta were measured by monitoring contrast enhancement in real time (bolus tracking). Cardiac output was measured by the geometric method during the CTA examination and was correlated with the contrast TT. Results: Forty-three individuals were analyzed. The mean contrast TT was 13.1 s overall (from the antecubital vein to the ascending aorta), 3.0 s from the superior vena cava to the pulmonary trunk, and 7.2 s from the pulmonary trunk to the ascending aorta. There was a tendency toward a correlation between contrast TT and cardiac output (p = 0.055). Conclusion: The reference values established here for contrast TTs among the superior vena cava, pulmonary trunk, and ascending aorta will serve as a basis for clinical evaluation.

Resumo O presente estudo foi realizado na microrregião de Ilhéus-Itabuna, Bahia. Os objetivos deste estudo foram determinar a soroprevalência de anticorpos contra Sarcocystis neurona em equinos da microrregião Ilhéus-Itabuna (BA) e identificar possíveis fatores associados à infecção. A presença de esporocistos/oocistos de Sarcocystis spp. também foi pesquisada em Didelphis spp. Foram coletadas 669 amostras de soro de equinos em 56 propriedades localizadas em 12 municípios da região. Foi utilizada a reação de imunofluorescência indireta (RIFI), utilizando-se lâminas confeccionadas com merozoítos de Sarcocystis neurona (cepa SN138) e ponto de corte na diluição de 1:80. A ocorrência de anticorpos anti- S. neurona, nos equinos amostrados, foi de 7,92%. As finalidades dos animais - comércio e trabalho - apresentaram-se significativas (p<0.05), sendo que a finalidade trabalho (21,6%) foi considerada fator de risco, enquanto a finalidade comércio (3,6%) foi considerada fator de proteção. Foram capturados 25 Didelphis spp., para pesquisa de esporocistos/oocistos em amostras de fezes e raspado de mucosa intestinal. Todos os Didelphis spp. foram negativos para a presença de Sarcocystis spp., mesmo assim essa circunstância não alterou o fato da ocorrência de S. neurona ter sido observada em cavalos criados na mesorregião do sul da Bahia.
Abstract The aims of this study were to determine the seroprevalence of Sarcocystis neurona antibodies in equines in the Ilhéus-Itabuna microregion (BA), and identify possible factors associated with infection. The presence of sporocysts/oocysts of Sarcocystis spp. was also verified in Didelphis spp. A total of 669 serum samples were collected from equines in 56 properties located in 12 municipalities in the region. Indirect fluorescent antibody test was performed with slides containing merozoites of the S. neurona, using a cut-off titer of 1:80. Occurrence of 7.92% of anti-S. neurona antibodies was observed in the sampled equines. The purposes trade and work were significantly associated with the presence of antibodies (p<0.05), and being used for the purpose of work (21.6%) was considered a risk factor, while being used for the purpose of trade (3.6%) was a protective factor. A total of 25 Didelphis spp. was captured for research on sporocysts/oocysts in stool samples and intestinal scrapings, being all negative. Didelphis spp. were all negative for the presence of Sarcocystis spp. and this circumstance does not change the fact that seroprevalence of S. neurona has been observed in horses raised in the southern Bahia.

RESUMO: A leucoencefalomalácia (LEM) é uma enfermidade que acomete equídeos causada pela ingestão de milho e seus derivados e feno contaminados pela micotoxina fumonisina, um metabólito do fungo Fusarium verticillioides (sinônimo para F. moniliforme). Os sinais clínicos apresentam início agudo e evolução rápida e são decorrentes de lesões encefálicas. O objetivo deste estudo é descrever os achados clínicos de 11 equídeos diagnosticados com LEM, incluindo a análise do líquido cefalorraquidiano (LCR). 91% dos animais afetados eram equinos e somente 9% (1/11) era asinino. A localização clínica das lesões era 64% (7/10) cerebrais, manifestadas por alterações no estado mental e comportamento e 36% (4/10) no tronco encefálico, manifestadas por incoordenação, desvio lateral de cabeça, nistagmo, hipoalgesia da face e dificuldade de apreensão, mastigação e deglutição de alimentos. Comparativamente, os achados post mortem revelaram que 82% (9/11) das lesões eram no cérebro e 18% (2/11) no tronco encefálico. Alterações no LCR, tais como xantocromia (43%, 3/7), hiperproteinorraquia (50%, 3/6) e pleocitose (43%, 3/7), foram observadas. Os animais afetados apresentaram sinais clínicos compatíveis com lesões encefálicas e/ou de tronco cerebral. O LCR de animais com LEM pode apresentar xantocromia, hiperproteinorraquia, e pleocitose, reforçando que esta doença deve ser incluída como diagnóstico diferencial de encefalomielites.
ABSTRACT: Equine leukoencephalomalacia (LEM) is a disease caused by the ingestion of food, especially corn, contaminated by fumonisin, a Fusarium verticillioides (synonymous with F. moniliforme) metabolite. The clinical signs of brain injuries have an acute onset and rapid evolution. This study aimed to describe the clinical findings in 11 animals diagnosed with LEM, including cerebrospinal fluid (CSF) analysis. Of these animals, 91% (10/11) were horses, and only 9% (1/11) were asinine. The clinical localization of the lesions was 64% (7/10) cerebral, manifested mainly by altered mental state and behavioral disturbance, and 36% (4/11) were brainstem lesions, manifested by incoordination, head tilt, nystagmus, facial hypoalgesia, difficulty in apprehension, chewing, and swallowing food. Postmortem findings revealed that 82% (9/11) of the lesions were in the cerebrum and 18% (2/11) in the brainstem. CSF findings, such as xanthochromia (43%, 3/7), hyperproteinorrachia (50%, 3/6), and pleocytosis (43%, 3/7) were observed. The affected animals showed neurological signs that were compatible with cerebral and/or brainstem injuries. The CSF from animals with LEM may present with xanthochromia, hyperproteinorrachia, and pleocytosis, reinforcing the fact that this disease should be included in the differential diagnosis of encephalomyelopathies.

Objective: To explore the role of personality traits in at-risk drinking and current cannabis use among medical students. Methods: This cross-sectional study evaluated 707 medical students from two universities. Multiple logistic regression models for at-risk drinking and current cannabis use were constructed including sociodemographic, psychiatric, and personality variables. Results: At-risk drinking and current cannabis use were reported by 19.3% and 14.9% of participants, respectively. Models including Big Five measures showed associations of at-risk drinking with higher extraversion (p < 0.00001, adjusted odds ratio [AOR] = 1.9) and lower conscientiousness (p = 0.00001, AOR = 0.5); cannabis use was also associated with lower conscientiousness (p = 0.003, AOR = 0.6), besides higher openness to experience (p = 0.002, AOR = 1.9). Models including measures of the Behavioral Inhibition and Activation Systems scales (BIS/BAS) showed associations of at-risk drinking with lower BIS (p = 0.002, AOR = 0.9) and higher BAS fun-seeking (p = 0.0005, AOR = 1.2); cannabis use was also associated with higher BAS fun-seeking (p = 0.008, AOR = 1.2). Personality variables had modest effects on model fit. Conclusion: Specific personality traits were independently associated with at-risk drinking and current cannabis use, albeit with modest effect sizes.

Abstract The spread of SARS-CoV-2 and the distribution of cases worldwide followed no clear biogeographic, climatic, or cultural trend. Conversely, the internationally busiest cities in all countries tended to be the hardest hit, suggesting a basic, mathematically neutral pattern of the new coronavirus early dissemination. We tested whether the number of flight passengers per time and the number of international frontiers could explain the number of cases of COVID-19 worldwide by a stepwise regression. Analysis were taken by 22 May 2020, a period when one would claim that early patterns of the pandemic establishment were still detectable, despite of community transmission in various places. The number of passengers arriving in a country and the number of international borders explained significantly 49% of the variance in the distribution of the number of cases of COVID-19, and number of passengers explained significantly 14.2% of data variance for cases per million inhabitants. Ecological neutral theory may explain a considerable part of the early distribution of SARS-CoV-2 and should be taken into consideration to define preventive international actions before a next pandemic.

It was our objective to verify the time course of muscle thickness and cytokine concentration after a resistance training session. In one of the experimental conditions, the training session was performed with low load (20% 1RM) and restriction of blood flow. In the other experimental condition, the same training was performed with high load (80% 1RM) and without blood flow restriction. Femoral rectus muscle, vastus lateralis, brachial biceps and triceps brachii muscle thickness and the serum cytokine dosage were analyzed pré, 0h, 24h and 48h after the training sessions. For the upper and lower limbs, the main results showed significant (p< 0.05) effect on time for the thickness in all muscle but not (p> 0.05) to experimental condition. To cytokines concentrations, a significant (p= 0.004) interaction between the time and conduction for IL10. Conversely, there was no difference between the weeks (p= 0.698) or time (p= 0.142) in the means of TNF. In conclusion both experimental conductions promoted similar changes on muscular swelling without alterations on TNFa, however, the RST protocol induced increase on IL-10 concentration after 24 hours of exercise session.

RESUMO A osmose reversa é uma tecnologia amplamente conhecida para purificar as águas dos poços salinos. Devido à geração do rejeito salino nas estações de dessalinização por osmose reversa, a avaliação da vulnerabilidade para definir as áreas críticas de monitoramento das águas do processo de dessalinização tem sido uma ferramenta importante para delinear as redes de monitoramento necessárias para a vigilância de possíveis locais de salinização. Objetivou-se neste estudo avaliar a qualidade das águas amostradas em estações de dessalinização na Mesorregião do Oeste Potiguar Brasileiro por meios de um índice de qualidade capaz de fornecer uma avaliação relativa da vulnerabilidade das águas ao potencial de salinização. O presente estudo propõe um índice de avaliação da qualidade das águas das estações de dessalinização utilizando inicialmente os parâmetros químicos condutividade elétrica, relação de adsorção de sódio, relação Mg2+/Ca2+ e os íons sódio, cloreto e bicarbonato. O índice de avaliação da qualidade das águas das estações de dessalinização apresentou bom desempenho, podendo ser acrescido de parâmetros referentes ao solo e à cultura explorada. Os altos valores de índice relativo de qualidade das águas das estações de dessalinização são apontados como indicadores de possíveis riscos de salinização de solos e de contaminação de aquíferos subterrâneos. O maior grau de impacto do uso da terra em consequência da qualidade das águas de estações de dessalinização foi registrado em amostras de rejeito salino seguidas das águas de poços.
ABSTRACT Reverse osmosis is the technology commonly used to produce fresh water from brackish groundwater. Due to the reject brine generated in desalination plants by reverse osmosis, vulnerability assessment to define critical areas to monitor waters from desalination has been an important tool for delineating the monitoring networks required for surveillance of potential salinization sites. The objective of this study was to assess the quality of waters sampled in desalination plants by a quality index, which provides a relative assessment of water vulnerability to potential salinization. The present study proposes an index to assess the quality of waters from desalination plants initially using the chemical parameters electrical conductivity, sodium adsorption ratio, Mg2+/Ca2+ ratio, and the ions sodium, chloride and bicarbonate. The index to assess quality of waters from desalination plants showed good performance and can include additional parameters referring to the soil and crop exploited. High values of the relative index of quality of waters from desalination plants are considered as possible indicators of risk of soil salinization and groundwater contamination. The highest level of land use impact on the quality of waters from desalination plants was found in reject brine samples followed by well water samples.

Microscopic techniques were combined to study the influence of corrosion rate on the morphologic behavior of AISI 1020 steel specimens submitted to thermal degradation of a typical acid crude oil (total acid number (TAN) = 2.1390 mg KOH g-1 and total sulfur (S) = 0.7778 wt.%). The techniques used were light microscopy (LM), scanning electron microscopy/energy dispersive spectroscopy (SEM/EDX), atomic force microscopy (AFM) as well as Raman spectroscopy. Assays were performed in six different degradation time (t = 6, 12, 24, 36, 48 and 72 h) at 320 ºC. After the exposure of the specimens to petroleum, a reduction above 37% in the TAN after t = 72 h was observed, with a maximum corrosion rate during the first periods of degradation (t = 6 and 12 h). Correlating the TAN and corrosion rate data with the microscopic data, the images of LM, AFM, and SEM/EDX showed that after 6 h of exposure to petroleum, a passivation film was formed on the surface of the steel. This film consisted of two layers, an external one, formed of FeS, and an internal one, composed of iron oxides and oxyhydroxides. However, after 48 h of thermal degradation, this morphology was altered to a single layer of FeS coating the steel surface.

RESUMO INTRODUÇÃO: As infecções relacionadas com a assistência à saúde (IRAS) ocorrem durante a internação como resultado de morbidade subjacente, procedimentos invasivos, patologia aguda ou tratamento médico. Elas levam à prolongada permanência e, consequentemente, à carga econômica. A principal ferramenta para conter essas infecções são os antimicrobianos. No entanto, o aumento da resistência e a baixa taxa de descoberta de novos medicamentos justificam a pesquisa que avalia o perfil de resistência de microrganismos aos antimicrobianos. OBJETIVO: Avaliar a prevalência e o perfil de suscetibilidade antimicrobiana das IRAS ocorridas em um hospital filantrópico de referência do Espírito Santo, Brasil. MÉTODOS: Estudo observacional, retrospectivo e transversal, entre julho de 2014 e junho de 2016. Os dados sobre cultura de sangue, urina e secreções corporais foram coletados da base de dados do Centro de Controle de Infecção Hospitalar. RESULTADOS: Houve alta prevalência de IRAS em pacientes com mais de 60 anos. Duzentos e quarenta e três (47.55%) pacientes eram do sexo feminino. As quatro bactérias mais prevalentes foram: Acinetobacter spp., Klebsiella pneumoniae, Pseudomonas aeruginosa e Staphylococcus aureus. A polimixina foi a droga que apresentou os melhores efeitos antimicrobianos. CONCLUSÃO: A polimixina foi ativa in vitro contra todos os isolados de Acinetobacter spp. Quanto à K. pneumoniae, tanto a polimixina quanto a amicacina apresentaram eficácia significativa. Em relação à Pseudomonas aeruginosa, a polimixina foi efetiva em todas as amostras. Já em relação ao S. aureus, teicoplanina, daptomicina e vancomicina foram efetivas em todas as amostras. A polimixina demonstrou um bom desempenho geral in vitro.
ABSTRACT INTRODUCTION: Healthcare associated infections (HAIs) occur during the hospital stay as a result of underlying morbidity, invasive procedures, acute pathology or medical treatment. They lead prolonged stay and, consequently, to an increase in financial charges. The main tool to control these infections is the use of antimicrobials. However, the increase in resistance and the low frequency of discovery of new drugs justify the research that evaluates the resistance profile of microorganisms to antimicrobials. OBJECTIVE: To evaluate the prevalence and antimicrobial susceptibility profile of HAIs at a philanthropic reference hospital in Espírito Santo, Brazil. METHODS: Observational, retrospective and cross-sectional study, between July 2014 and June 2016. Data on blood, urine and corporal secretions culture were collected from the data base of the Hospital Infection Control Commission. RESULTS: There was a high prevalence of HAIs in patients older than 60 years. Two hundred and forty three (47.55%) patients were female. The four most prevalent bacteria were: Acinetobacter spp., Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. Polymyxin was the drug which presented the best antimicrobial effects. CONCLUSION: Polymyxin was active in vitro against all isolates of Acinetobacter spp. Regarding K. pneumoniae, both polymyxin and amikacin showed a significant effectiveness. Regarding Pseudomonas aeruginosa, polymyxin was effective in all samples. Regarding S. aureus, teicoplanin, daptomycin and vancomycin were effective in all samples. Polymyxin showed a good overall in vitro activity.

Resumo: A Reserva Biológica Tinguá (RBT) é a maior área protegida desta categoria no estado do Rio de Janeiro. Aqui, pela primeira vez, apresentamos a composição histórica da assembleia de mamíferos terrestres da região da RBT. Um inventário foi realizado utilizando amostragem por transectos, transectos não padronizados, busca por espécimes em museu e relatos. Considerando todos os dados, foram registradas oitenta e cinco espécies, colocando a RBT como a segunda no número de mamíferos registrados na ecorregião "Serra do Mar" da Mata Atlântica e no estado do Rio de Janeiro. Entre as espécies com registros históricos estão a onça-pintada (Panthera onca) e o mico-leão-dourado (Leontopithecus rosalia), enquanto a presença atual do lobo-guará (Chrysocyon brachyurus) foi registrada pela primeira vez. Estudos prioritários devem se concentrar nas ordens de Chiroptera, Rodentia e Didelphimorphia, especialmente nas áreas mais remotas da reserva, e pesquisas de longo prazo sobre espécies ameaçadas de extinção. Além da caça, a fragmentação em seu interior por estradas, gasodutos e linhas de transmissão e a presença de espécies exóticas, a TBR é ameaçada também pelo crescimento urbano no entorno e pela pressão para reduzir sua área e categoria de proteção, exigindo maior atenção dos altos níveis de gestão de áreas protegidas no Brasil.
Abstract: The Tinguá Biological Reserve (TBR) is the largest protected area of this category in Rio de Janeiro state. Here, for the first time, we present the historical composition of terrestrial mammals' assemblage of TBR region. An inventory was conducted using transect surveys, nonstandard transects, survey of museum specimens and informal reports. Considering all the data, eighty-five species were recorded, placing TBR as the second one in the number of mammals recorded in "Serra do Mar" ecoregion of Atlantic Forest and in the Rio de Janeiro state. Among the species with historical records are the jaguar (Panthera onca) and the golden-lion-tamarin (Leontopithecus rosalia) while the current presence of the maned wolf (Chrysocyon brachyurus) was recorded for the first time. Priority studies should focus on Chiroptera, Rodentia and Didelphimorphia orders, especially in the most remote areas of the reserve, and long-term surveys of endangered species. Besides hunting, fragmentation of its interior by roads, pipelines and transmission lines and exotic species, TBR is also threatened by the urban growth around it and the pressure to reduce its area and its protection category, demanding greater attention by the high levels of governance of protected areas in Brazil.

RESUMO As características regionais das águas dos aquíferos aluvionais são diferentes, uma vez que dependem da geologia e do clima. Também pode haver variação local da qualidade da água disponível quando a fonte hídrica é superficial (rios e lagos) ou subterrânea em função da geologia. Objetivando investigar a qualidade da água subterrânea do aquífero aluvial na Sub-Bacia do Rio das Cobra (RN) para fins de construção de barragens subterrâneas, foram monitorados 5 poços amazonas, 4 no rio principal e 1 do afluente, em épocas de estiagem e chuvosa, durante 2 anos hidrológicos. Para caracterização hidroquímica do aquífero foram coletadas 15 amostras de água dos poços amazonas. A origem da recarga dos aquíferos e avaliação hidroquímica da água foram avaliadas utilizando-se a análise estatística multivariada. Os resultados da avaliação hidroquímica indicaram que os íons Na+ e Cl- são mais influentes na salinização da área estudada. Há riscos de agravamento dos problemas de salinidade e toxicidade no médio e baixo curso da Sub-Bacia do Rio Cobra.
ABSTRACT The regional characteristics of waters from alluvial aquifers are different, since they depend on geology and climate. Also, there may be local variation in the quality of the available water when the water source is superficial (rivers and lakes) or is underground due to geology. In order to investigate the groundwater quality of the alluvial aquifer in the Sub-Basin of the Cobra River (RN) for construction of underground dams, five wells, four in the main river and one in the tributary, were monitored in dry and rainy seasons, during two hydrological years. Fifteen water samples from ‘Amazonas’ wells were collected for hydrochemical assessment. Multivariate analysis were performed to evaluate the origin of aquifer recharge and water hydrochemical characteristics. Hydrochemical assessment results indicated that Na+ and Cl- ions have greater influence on the salinization of the studied area. There are risks of worsening salinization and toxicity problems in the middle and lower courses of the Cobra River Sub-Basin.

Objective: Rapid cycling (RC) is a feature of bipolar disorder (BD) that has been associated with worse outcome and more severe disability. Our goal was to investigate the association of demographic and clinical factors with RC. Methods: We compared RC and non-rapid cycling (NRC) BD patients from the Brazilian Research Network in Bipolar Disorder (BRN-BD) regarding age at onset of BD; total number of episodes; previous number of manic, depressive, mixed, and hypomanic episodes; polarity of the first episode; gender; number of suicide attempts; number of lifetime hospitalizations and lifetime history of at least one hospitalization; family history of mood disorder; clinical comorbidities such as hypothyroidism, hyperthyroidism, seizures; and current use of medications such as lithium, anticonvulsants, antipsychotics, and antidepressants. Results: We studied 577 patients and found that 100 (17.3%) met the criteria for RC in the year before the investigation. RC patients had earlier age at onset, longer duration of disease, more lifetime depressive and manic episodes, higher number of suicide attempts, and higher rate antidepressant use. Conclusion: The presence of RC in the previous year was associated with specific clinical characteristics closely related to worse outcome in the course of BD.
