ABSTRACT Seasonal Forests (FE) occurring in the Cerrado, are characterized by the presence of tree species with different deciduous levels on dry seasons and vary in floristic composition depending on their geographic location. The present work has as premise that the floristic-structural patterns of these forests can be remarkable, due to the environmental conditions imposed by the environments and proximity to different watersheds. We used sample data of 17 fragments of Semideciduous Seasonal Forest (FE) in the Cerrado. For each sampling site to be inventoried an area of one hectare where the circunference of all the trees were measured at 1.30cm ≥ 15cm were included. An Principal Component Analysis - PCA, including abiotic and structural variables of each forest were made. For similarity analysis we used the floristic data in an absence-presence matrix of species and a number of trees of each species data. To determine floristic patters we use the Sorensen and Bray-Curtis similarity and made a cluster with the Unweighted Average Grouping Method (UPGMA). To explore the patterns of abundance performed in the Non-Metric multidimensional Scale (nMDS). The floristic-structural patterns indicated the presence of two distinct floristic groups, a smaller group formed different areas of the Araguaia and Paraguay River watersheds, and another large group formed by areas of the Paraná basin, and other others, even basin, more dissimilar than too much. The formation of floristic groups reflects that, as analyzed communities, there are several generalist species that are not very demanding and that adapt to new conditions, occurring in non-Cerrado and Atlantic Forest seasonal forest areas, forming two diverse tests located mainly in the Araguaia basin and Paraná.

RESUMO As Florestas Estacionais Sazonalmente Secas (FESS) ocorrentes no Cerrado são caracterizadas pela presença de espécies arbóreas com diferentes níveis de caducifólia nos períodos de estação seca e variam na composição florística dependendo da sua localização geográfica. O presente trabalho tem como objetivo assumir que os padrões florístico-estruturais destas florestas podem ser marcantes, devido às condições ambientais impostas nos ambientes e proximidade com bacias hidrográficas distintas. Foram utilizados levantamentos fitossociológicos realizados em um hectare para 17 fragmentos de Floresta Estacional Semidecidual (FES), onde aferiu-se todos os indivíduos arbóreos a circunferência a altura do peito (CAP) de 1,30cm ≥ 15cm. A avaliação foi feita por meio de uma ordenação por Análise de Componente Principal incluindo variáveis abióticas e estruturais de cada floresta. Para análise de similaridade, foram utilizados dados florísticos em uma matriz de presença-ausência utilizando os dados de ocorrência das espécies identificadas em cada localidade. Para determinar as semelhanças, utilizou-se o coeficiente de similaridade de Sorensen, o índice de Bray-Curtis e o método de agrupamento das médias não ponderadas (UPGMA). Para explorar padrões de abundância, foi feito o Escalonamento Multidimensional Não Métrico (nMDS). Os padrões florísticos-estruturais apontaram a presença de dois grupos florísticos distintos, um menor grupo formando diferentes áreas das bacias hidrográficas do Rio Araguaia e Rio Paraguai, e outro grande grupo formado por áreas da bacia do Paraná, e outras desta mesma bacia, porém mais dissimilares do que as demais. A formação de grupos florísticos reflete que as comunidades analisadas possuem diversas espécies generalistas, pouco exigentes e que se adaptam bem a novas condições, com ocorrência para áreas de florestas estacionais no Cerrado e Mata Atlântica, formando duas províncias distintas situadas, sobretudo na bacia do Araguaia e Paraná.

Abstract Objective: Identify the one-year survival rate and major complications in patients submitted to pneumonectomy for infectious disease. Methods: Retrospective data from all cases of infectious disease pneumonectomy over the past 10 years were collected from two reference centers. The authors analyzed: patient demographics, etiology, laterality, bronchial stump treatment, presence of previous pulmonary resection, postoperative complications in the first 30 days, the treatment used in pleural complications, and one-year survival rate. Results: 56 procedures were performed. The average age was 44 years, with female predominance (55%). 29 cases were operated on the left side (51%) and the most frequent etiology was post-tuberculosis (51.8%). The overall incidence of complications was 28.6% and the most common was empyema (19.2%). Among empyema cases, 36.3% required pleurostomy, 27.3% required pleuroscopy and 36.3% underwent thoracoplasty for treatment. Bronchial stump fistula was observed in 10.7% of cases. From all cases, 16.1% were completion pneumonectomies and 62.5% of these had some complication, a significantly higher incidence than patients without previous surgery (p = 0.0187). 30-day in-hospital mortality was (7.1%) with 52 cases (92.9%) and 1-year survival. The causes of death were massive postoperative bleeding (1 case) and sepsis (3 cases). Conclusions: Pneumonectomy for benign disease is a high-risk procedure performed for a variety of indications. While morbidity is often significant, once the perioperative risk has passed, the one-year survival rate can be very satisfying in selected patients with benign disease.

ABSTRACT The Caatinga biome in Brazil comprises the largest and most continuous expanse of the seasonally dry tropical forest (SDTF) worldwide; nevertheless, it is among the most threatened and least studied, despite its ecological and biogeographical importance. The spatial distribution of volumetric wood stocks in the Caatinga and the relationship with environmental factors remain unknown. Therefore, this study intends to quantify and analyze the spatial distribution of wood volume as a function of environmental variables in Caatinga vegetation in Bahia State, Brazil. Volumetric estimates were obtained at the plot and fragment level. The multiple linear regression techniques were adopted, using environmental variables in the area as predictors. Spatial modeling was performed using the geostatistical kriging approach with the model residuals. The model developed presented a reasonable fit for the volume m3 ha with r2 of 0.54 and Root Mean Square Error (RMSE) of 10.9 m3 ha–1. The kriging of ordinary residuals suggested low error estimates in unsampled locations and balance in the under and overestimates of the model. The regression kriging approach provided greater detailing of the global wood volume stock map, yielding volume estimates that ranged from 0.01 to 109 m3 ha–1. Elevation, mean annual temperature, and precipitation of the driest month are strong environmental predictors for volume estimation. This information is necessary to development action plans for sustainable management and use of the Caatinga SDTF in Bahia State, Brazil.

Abstract This work is a floristic study of Selaginella in Maranhão. The species survey is based on collections from fieldwork conducted between April 2006 and February 2023 and specimens from Maranhão deposited at the CCAA, HBRA, MG, and SLUI herbaria. Ten species were identified: Selaginella conduplicata, S. convoluta, S. erythropus, S. flagellata, S. gynostachya S. marginata, S. minima, S. radiata, S. simplex, and S. sulcata. We report the first record of S. gynostachya for Maranhão and the Cerrado domain in Brazil. Until now, this species was only known from areas of Amazonia. We provide a map with records, an identification key, and comments about the identification and geographic distribution of Selaginella species in Maranhão state. For the new record, we also provide photos.

RESUMO A reconstrução do terço distal da tíbia devido à ressecção de tumor maligno apresenta alguns fatores que dificultam sua realização, como camada subcutânea delgada, feixes neurovasculares que transpassam os compartimentos, tempo cirúrgico prolongado, material ortopédico específico e equipe multidisciplinar treinada. O aloenxerto de banco de tecido faz parte deste arsenal ortopédico. Objetivo: Descrever o protocolo realizado no Instituto Nacional de Traumatologia e Ortopedia Jamil Haddad. Métodos: Série de seis casos submetidos à ressecção com margens oncológicas, reconstrução com aloenxerto e uso de haste retrógrada de tornozelo como cirurgia preservadora do membro. Três dos seis pacientes eram do sexo feminino, as lesões tinham em média 9,3 cm de comprimento e o tempo cirúrgico médio foi de 3,25 horas. Resultados: A principal complicação de curto prazo (≤ 30 dias) foi a paralisia do nervo fibular, enquanto a principal complicação de longo prazo (> 30 dias) foi a infecção do sítio cirúrgico (dois casos). A consolidação dos dois focos ocorreu em três pacientes, e dois pacientes evoluíram para pseudoartrose assintomática do foco proximal com consolidação do foco distal. Conclusão: Apesar das complicações, a cirurgia proposta permite ao paciente a chance de preservar seu membro diante de uma cirurgia radical imediata. Nível de Evidência IV, Série de Casos.

RESUMO Antecedentes: O Doppler transcraniano (DTC) é uma técnica não invasiva para a avaliação da hemodinâmica cerebral, porém existem controvérsias na literatura sobre sua aplicabilidade preditiva em situações de elevada pressão intracraniana (PIC). Objetivo: Investigar o fluxo sanguíneo cerebral pelo DTC e correlacioná-lo com as variações da PIC na fase aguda da hipertensão intracraniana em modelo animal. Métodos: Dois grupos de animais (suínos) foram submetidos a hipertensão intracraniana secundária à indução de diferentes volumes de hematoma, por meio da insuflação de balão intracraniano controlado com 4 e 7 mL de solução salina fisiológica (grupos A e B, respectivamente). Em seguida, administrou-se infusão venosa de solução salina hipertônica (SSH 3%). Foram coletados os valores dos parâmetros de PIC e DTC (velocidade sistólica [FVs], diastólica [FVd] e média [FVm] do fluxo sanguíneo cerebral), bem como o índice de pulsatilidade (IP). Comparações entre os parâmetros do DTC e o monitoramento da PIC foram realizadas. Resultados: Vinte porcos foram estudados, dez no grupo A e dez no grupo B. Correlação significativa entre IP e PIC foi obtida, principalmente logo após a elevação abrupta da PIC. Não houve correlação entre PIC e FVs, FVd ou FVm separadamente. Também não houve alteração significativa na PIC após a infusão de SSH. Conclusões: Esses resultados demonstram o potencial do IP como um bom parâmetro para a avaliação de pacientes com suspeita de elevação da PIC.

ABSTRACT Background: Transcranial Doppler has been tested in the evaluation of cerebral hemodynamics as a non-invasive assessment of intracranial pressure (ICP), but there is controversy in the literature about its actual benefit and usefulness in this situation. Objective: To investigate cerebral blood flow assessed by Doppler technique and correlate with the variations of the ICP in the acute phase of intracranial hypertension in an animal model. Methods: An experimental animal model of intracranial hypertension was used. The experiment consisted of two groups of animals in which intracranial balloons were implanted and inflated with 4 mL (A) and 7 mL (B) for controlled simulation of different volumes of hematoma. The values of ICP and Doppler parameters (systolic [FVs], diastolic [FVd], and mean [FVm] cerebral blood flow velocities and pulsatility index [PI]) were collected during the entire procedure (before and during hematoma simulations and venous hypertonic saline infusion intervention). Comparisons between Doppler parameters and ICP monitoring were performed. Results: Twenty pigs were studied, 10 in group A and 10 in group B. A significant correlation between PI and ICP was obtained, especially shortly after abrupt elevation of ICP. There was no correlation between ICP and FVs, FVd or FVm separately. There was also no significant change in ICP after intravenous infusion of hypertonic saline solution. Conclusions: These results demonstrate the potential of PI as a parameter for the evaluation of patients with suspected ICP elevation.

RESUMO: O quati (Nasua nasua, Linnaeus 1766) é uma espécie generalista que alimenta-se de comida humana frequentemente descartada em lixeiras ao redor de locais de turismo ecológico. Investigou-se o peso corporal e algumas variáveis da química sanguínea relacionadas à dieta de quatis selvagens de três parques: Parque Municipal das Mangabeiras (PM), Parque Nacional do Caparaó (PNC) e Estação Ecológica Água Limpa (EEAL). Testou-se o plasma de 75 quatis para lipoprotequatis sitaabeiras (PM), Parque Nacional do Caparaó (PNC) aspartato transaminase (AST), gama-glutamil transferase (GGT), colesterol (Chol), triglicerídeos (Trig) e fosfatase alcalina (ALP). Machos e fêmeas adultos não diferiram significativamente quanto a peso (P > 0,05) e índices de química sanguínea (P > 0,05). Os quatis adultos do PM foram mais pesados em relação aos quatis adultos dos outros dois parques. Houve diferenças significativas em HDL (P < 0,04), AST (P < 0,001), ALT (P < 0,001) e GGT (P < 0,001) entre os adultos dos três parques. Apenas ALT e ALP foram significativamente diferentes (P < 0,05) entre os quatis jovens. Os resultados sugerem que os quatis dos três parques apresentam diferentes estados de saúde. O consumo de alimentos humanos descartados parece afetar o peso corporal dos quatis do PM. Os quatis do PNC e da EEAL apresentaram perfis químicos sanguíneos sugestivos de doença hepática. Recomendamos a realização de programas de educação ambiental aos visitantes e investigações clínicas adicionais nos quatis desses parques.

ABSTRACT: The coati (Nasua nasua, Linnaeus 1766) is a generalist species, feeding on often-discarded human food in dumpsters around ecological tourism sites. We investigated the body weight and some blood chemistry variables related to the diet of wild coatis from three parks: Parque Municipal das Mangabeiras (PM), Parque Nacional do Caparaó (PNC) e Estação Ecológica Água Limpa (EEAL). We tested the plasma of 53 coatis for high-density lipoprotein (HDL), alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyl transferase (GGT), cholesterol (Chol), triglycerides (Trig), and alkaline phosphatase (ALP). Male and female adults did not significantly differ on the weight (P > 0.05) and blood chemistry indexes (P > 0.05). The adult coatis of the PM were heavier than the adult coatis of the other two parks. There were significant differences in HDL (P < 0.04), AST (P < 0.001), ALT (P < 0.001), and GGT (P < 0.001) between adults of the three parks. Only ALT and ALP were significantly different (P < 0.05) among the young coatis. The results suggested the coatis of the three parks have different health status. The consumption of discarded human food seems to affect body weight of the PM coatis. The coatis from PNC and EEAL had blood chemistry profiles suggestive of liver disorder. We recommend carrying on environmental education programs to visitors and additional clinical investigations on coatis from these parks.

São registradas 51 espécies distribuídas em 24 gêneros. Epífitas representam 86% das espécies, as demais são terrícolas (6%), hemiepífitas (6%) ou micoheterotrófica (2%). Os gêneros mais representativos foram Epidendrum (6 spp.) e Maxillaria (5 spp.). Este estudo registra pela primeira vez cinco gêneros (Coryanthes, Sarcoglottis, Stelis, Trichosalpinx e Wullschlaegelia) e dez espécies para a flora do Maranhão, dos quais, quatro também são novos registros para a Região Nordeste do Brasil. Uma chave de identificação, pranchas fotográficas dos novos registros e comentários taxonômicos, ecológicos e de distribuição geográfica são apresentados. Os dados evidenciam a importância dos fragmentos de Floresta Amazônica do Maranhão para a proteção das Orchidaceae, constantemente ameaçadas pelo desmatamento no Centro de Endemismo Belém.

Abstract This study provides an inventory of the Orchidaceae in one of the most threatened areas of the Brazilian Amazon, situated in the eastern portion of the Belém Endemism Center. A total of 51 species, distributed in 24 genera, are recorded. Epiphytes represent 86% of the species, the remaining are terricolous (6%), hemiepiphytic (6%) or myco-heterotrophic (2%). The most representative genera were Epidendrum (6 spp.) and Maxillaria (5 spp.). This study cites for the first time five genera (Coryanthes, Sarcoglottis, Stelis, Trichosalpinx and Wullschlaegelia) and ten species for the flora of Maranhão, of which four are new records to the Brazilian Northeast. An identification key, photographs of the new records, taxonomic and ecological comments, as well as geographic distribution are provided. The data reinforce the importance of the forest fragments of the Amazon Forest in Maranhão for the conservation of Orchidaceae which is constantly threatened by deforestation in the Belém Endemism Center.

ABSTRACT An updated checklist of the Orchidaceae from the state of Maranhão is provided. We confirmed 51 genera and 119 species, of which the most representative genera are Habenaria (17 spp.), Catasetum (14 spp.) and Epidendrum (10 spp.). Our checklist includes 30 species that are not listed in the Flora do Brasil for the state, many of which, however, have been recorded in previous publications. Thus, excluding these, six species are cited here for the first time to Maranhão, all of which are also new records for the Brazilian Northeast region. Comparing such data with previous lists, with 103 and 105 species, we detected a strong incongruity among the data. Of the former list, 25 species lack vouchers from the state and were not collected in our expeditions, thus these taxa are not confirmed, while of the latter we found 20 species that are also not confirmed for the same reasons. A list with the 34 excluded taxa is provided. Most of the collection effort in the state coincides with university campuses, and the northwestern region is the most species rich, but unfortunately it is also the most threatened area.

Abstract There are very few studies evaluating the exposure of the general population to food colours. This study aimed to estimate the Theoretical Maximum Daily Intake (TMDI) by the Brazilian population of four rather seldom-used synthetic food colours: Azorubine, Erythrosine, Indigotine, and Ponceau 4R. The study was conducted using data from the two most recent National Household Budget Surveys (carried out in 2008/2009 and 2017/2018). The study covered the country’s population, sorted into the following groups: gender, geographic region, and age (among people older than 10 years). The results show that the mean TMDI (mg/day) does not exceed the Acceptable Daily Intake (ADI) in any population group for any of the food colours. The highest values found were 12.5% of the ADI for Erythrosine in 2008/2009 and 4% in 2017/2018. A decrease in the mean TMDI was observed for all food colours comparing 2008/2009 and 2017/2018. Intake increases with decreasing age, adolescents being the group with the highest mean TMDI. When considering the prevalence of food consumption instead of the mean consumption, TMDI gets closer to the ADI, reaching 79% of the ADI of Erythrosine for adolescent females. The intake of these food colours proved to be within the recommended levels.

RESUMO O objetivo deste trabalho foi avaliar o efeito da inclusão de polpa cítrica na silagem de milho sobre a composição química e parâmetros de fermentação. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições. Os tratamentos foram: Silagem de milho sem polpa cítrica (0%); silagem de milho com 10% 39 de polpa cítrica; silagem de milho com 20% de polpa cítrica; silagem de milho com 30% de polpa cítrica; silagem de milho com 40% de polpa cítrica e silagem de milho com 50% de polpa cítrica. O pH diminuiu linearmente com à inclusão de polpa cítrica, gerando valores distantes do considerado adequado (3,8 a 4,2). Por outro lado, é possível inferior que nem todos os parâmetros fermentativos foram comprometidos, uma vez que, com a inclusão de 33% de polpa cítrica, é possível estimar 30,82 g/kg total N. Com a utilização 45 de 49% de polpa cítrica, é possível obter 95,16 g/kg de proteína bruta. De 21% a 22% de polpa cítrica, foi obtido 549,89 g/kg de fibra em detergente neutro e 678,11 g/kg de nutrientes digestíveis totais. A inclusão de até 30% de polpa cítrica melhorará significativamente a composição química da silagem de milho, devido à redução nos valores de carboidrato estrutural e aumentos nos nutrientes digestíveis totais e proteína.

ABSTRACT The objective of this study was to evaluate the effects of including citrus pulp in maize silage on chemical composition and fermentation parameters. The experimental design was fully randomized with four replicates. Maize silage consisting of 0–50% citrus pulp was produced and analyzed. The pH linearly decreased with the increased inclusion of citrus pulp (3.49 at 50% citrus pulp), which is far below what is considered adequate (3.8–4.2). However, not all fermentation parameters were compromised. At 33% citrus pulp, we estimated 30.82 g/kg total nitrogen. At 49% citrus pulp, we estimated 95.16 g/kg of crude protein. At 21% and 22% citrus pulp, we estimated 549.89 g/kg of neutral detergent fiber and 678.11 g/kg of total digestible nutrients, respectively. Therefore, we conclude that the inclusion of up to 30% citrus pulp improves the complete chemical composition of maize silage owing to the reduction in structural carbohydrate values and increases in total digestible nutrient and protein content.

ABSTRACT Purpose: To determine the normal optical nerve sheath (ONS) diameter ultrasonography (ONSUS) and evaluate the possible effects of drugs on ONS diameter during anesthetic induction in healthy pigs. Methods: Healthy piglets were divided into three groups: a control group, that received xylazine and ketamine (X/K); other that received xylazine, ketamine and propofol (X/K/P); and a third group that received xylazine, ketamine, and thiopental (X/K/T). The sheath diameter was assessed by ultrasonography calculating the average of three measurements of each eye from the left and right sides. Results: 118 animals were anesthetized (49 X/K 33 X/K/P and 39 X/K/T). Mean ONS sizes on both sides in each group were 0.394 ± 0.048 (X/K), 0.407 ± 0.029 (X/K/P) and 0.378 ± 0.042 cm (X/K/T) (medians of 0.400, 0.405 and 0.389, respectively). The ONS diameter varied from 0.287–0.512 cm (mean of 0.302 ± 0.039 cm). For group X/K, the mean diameter was 0.394 ± 0.048 cm. Significant differences in ONS sizes between the groups P and T (X/K/P > X/K/T, p = 0.003) were found. No statistically significant differences were detected when other groups were compared (X/K = X/K/P, p = 0.302; X/K = X/K/T, p = 0.294). Conclusions: Sedation with thiopental lead to significative ONS diameter reduction in comparison with propofol. ONSUS may be useful to evaluate responses to thiopental administration.

Abstract Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.

Abstract: En | Text: En | PDF: En

BACKGROUND In Brazil, the yellow fever virus (YFV) is maintained in a sylvatic cycle involving wild mosquitoes and non-human primates (NHPs). The virus is endemic to the Amazon region; however, waves of epidemic expansion reaching other Brazilian states sporadically occur, eventually causing spillovers to humans. OBJECTIVES To report a surveillance effort that led to the first confirmation of YFV in NHPs in the state of Minas Gerais (MG), Southeast region, in 2021. METHODS A surveillance network was created, encompassing the technology of smartphone applications and coordinated actions of several research institutions and health services to monitor and investigate NHP epizootics. FINDINGS When alerts were spread through the network, samples from NHPs were collected and YFV infection confirmed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and genome sequencing at an interval of only 10 days. Near-complete genomes were generated using the Nanopore MinION sequencer. Phylogenetic analysis indicated that viral genomes were related to the South American genotype I, clustering with a genome detected in the Amazon region (state of Pará) in 2017, named YFVPA/MG sub-lineage. Fast YFV confirmation potentialised vaccination campaigns. MAIN CONCLUSIONS A new YFV introduction was detected in MG 6 years after the beginning of the major outbreak reported in the state (2015-2018). The YFV strain was not related to the sub-lineages previously reported in MG. No human cases have been reported, suggesting the importance of coordinated surveillance of NHPs using available technologies and supporting laboratories to ensure a quick response and implementation of contingency measures to avoid YFV spillover to humans.
