ABSTRACT Introduction: Graves' orbitopathy (GO) is a debilitating disorder in patients with autoimmune thyroid disease, mainly Graves' disease, which develops in 30 to 50% of cases. Objectives: To describe the clinical-ophthalmological characteristics and evolution of patients with moderate-to- severe active GO treated with methylprednisolone boluses who attended the Central Hospital of the Institute of Social Security between January 2018 and September 2021. Materials and methods: Observational design research, descriptive, retrospective study. Results: Records of 34 patients with active moderate-to-severe GO who received boluses of methylprednisolone based on the EUGOGO 2016 guidelines, were reviewed, of which 3 patients were excluded due to having incomplete records and another 3 patients since they required second-line treatment prior to end the 12-session scheme. Of the 28 patients studied, the average age was 43.6 ±13.1 years, 89% were female and 28.5% were smokers. Regarding the thyroid function of the population prior to treatment, hyperthyroidism was found in 82%, hypothyroidism in 11% and euthyroidism in 7%; and after treatment, hyperthyroidism was found in 78.6% (subclinical), euthyroidism in 17.9% and hypothyroidism in 3.5%. The majority (92.6%) had positive thyrotropin receptor antibodies, with an average of 18 ± 9.9 mIU/Ml. Regarding the activity of orbitopathy according to the CAS scale, an average of 4.1 ±1.0 was found before treatment and 1.2 ±1.4 after; Of them, 46.4% presented a mild condition according to the severity scale, 39% without severity criteria and 14% persisted in moderate-severe. Improvement in visual acuity was noted after treatment (57.1%), the average exophthalmia before treatment was 22.2 mm and after 21.1 mm; Diplopia occurred in 7.1% before treatment and in 3.6% after treatment. Conclusion: Treatment with intravenous glucocorticoids in moderate-severe Graves' orbitopathy (EUGOGO 2016 scheme) was very effective, reversing the activity and consequently helping to reduce the severity, in the vast majority of our patients. This could be explained because the orbitopathy was incipient and by the high degree of patient adherence in the context of well-protocolized multidisciplinary management.

RESUMEN Introducción: La oftalmopatía tiroidea (OT) es un trastorno debilitante en pacientes con enfermedad tiroidea autoinmune, principalmente enfermedad de Graves, que se desarrolla entre el 30 a 50% de los casos. Objetivos: Describir las características clínico-oftalmológicas y la evolución de los pacientes con oftalmopatía tiroidea activa moderada severa tratados con bolos de metilprednisolona que acuden al Hospital Central del Instituto de Previsión Social en el tiempo comprendido entre enero de 2018 y setiembre de 2021. Materiales y métodos: Investigación de diseño observacional, con estudio descriptivo, retrospectivo. Resultados: Se revisaron fichas de 34 pacientes con OT activa moderada severa que recibieron bolos de metilprednisolona basado en las guías EUGOGO 2016, de los cuáles se excluyeron 3 pacientes por tener fichas incompletas y otros 3 pacientes ya que requirieron tratamiento de segunda línea previo al término del esquema de 12 sesiones. De los 28 pacientes estudiados, la edad promedio fue de 43,6 ±13,1 años, el 89% de sexo femenino y el 28,5%, fumadores. En cuanto a la función tiroidea de la población previo al tratamiento, se constató hipertiroidismo en el 82%, hipotiroidismo en el 11% y eutiroidismo en el 7%; y posterior al tratamiento, se constató hipertiroidismo en el 78,6% (subclínico), eutiroidismo en el 17,9% e hipotiroidismo en el 3,5%. La mayoría (92.6%) contaba con anticuerpos contra el receptor de TSH positivo, con un promedio de 18 ± 9,9 mIU/Ml. Respecto a la actividad de la oftalmopatía según la escala CAS, se constató un promedio de 4,1 ±1,0 previo al tratamiento y posterior 1,2 ±1,4; de ellos el 46,4% presentó un estado leve según escala de gravedad, 39% sin criterios de gravedad y 14 % persistió en moderada -severa. Se constató mejoría de la agudeza visual tras el tratamiento (57,1%), el promedio de exoftalmía previo al tratamiento fue 22,2 mm y posterior 21,1 mm; se presentó diplopía en el 7,1% previo al tratamiento y en el 3,6% posterior al tratamiento. Conclusión: El tratamiento con glucocorticoides endovenosos en la oftalmopatía de Graves moderada-severa (esquema EUGOGO 2016) fue muy efectivo, revirtiendo la actividad y consecuentemente ayudando a disminuir la gravedad, en la gran mayoría de nuestros pacientes. Esto podría explicarse porque la oftalmopatía era incipiente y por el alto grado de adherencia de los pacientes en el contexto de un manejo multidisciplinar bien protocolizado.

ABSTRACT Myrtaceae has ca. 6,000 species, distributed into 140 genera with Pantropical distribution. The family is one of the five most representative flowering plants in species richness in Brazilian restinga and is also of great importance for the maintenance of the ecological cycles of this vegetation. However, few studies focus on Myrtaceae in restinga, mainly in the State of Bahia, which has the country's largest coastal extension. This study aims to present the first taxonomic study of Myrtaceae from the restinga of the State of Bahia, Brazil. A total of 10 field trips were performed from September 2016 to April 2019, and the most relevant herbaria of Brazil were consulted. A total of eight genera and 85 species of Myrtaceae were identified in the Bahian restinga. Myrcia was the most representative genus with 42 species, followed by Eugenia (23 spp.), Psidium (seven spp.), Campomanesia (five spp.), Myrciaria (four spp.), Neomitranthes (two spp.), and Blepharocalyx and Calycolpus (a single species each). Two of them represented new species to science, and four presented the first records to the studied area. The distribution patterns among the Brazilian biomes and the restinga phytophysiognomies are discussed, also a checklist, identification keys, and photographic plates are provided.

Abstract It is presented the first taxonomic study of the tribe Coreopsideae (Asteraceae) in Northeastern Brazil. A total of seven genera and 16 species were recorded in the region, with Bidens being the richest genus (8 spp.). Bidens tenera and Cosmos bipinnatus were recorded for the first time to the region, and Heterosperma ovatifolium represents the first record to Brazil. Bidens, Chrysanthellum, and Dahlia are taxonomically problematic that is reflected by several misidentifications found in the herbaria collections. Coreopsis, Cosmos, and Dahlia species are cultivated as ornamental but are scarcely represented in the herbaria. This study provides a checklist, an identification key to all species, in addition to discussing the importance of studying alien species for a better understanding of the Brazilian flora.

Resumo Como resultado dos nossos estudos em Coreopsideae no Nordeste do Brasil, apresentamos o primeiro registro de Heterosperma (H. ovatifolium) para o País.

The genus currently comprises 11 species, occurring from southwestern United States to South America and the West Indies. We present a complete morphological description, a photo plate, and a distribution map with the updated distribution for H. ovatifolium. Additionally, we present an updated identification key for the genera of Coreopsideae for Brazil.

Resumo A Área de Proteção Ambiental das Lagoas e Dunas do Abaeté (APA Abaeté) constitui um fragmento urbano de restinga no município de Salvador, estado da Bahia, Brasil. A área sofre com o descarte irregular de resíduos sólidos, a retirada clandestina de areia das dunas, a supressão e fragmentação da cobertura vegetacional original e o crescimento urbano dos bairros circundantes. Um estudo florístico recente revelou novos registros de espécies de orquídeas para esta Unidade de Conservação, mas destacou que a flora orquidológica está fortemente ameaçada. Neste contexto, foi realizado um estudo taxonômico das orquídeas da APA Abaeté, com o objetivo de facilitar o reconhecimento das espécies em campo e apoiar o estabelecimento de ações de conservação locais mais eficazes para as orquídeas, que devem abranger a dispersão manual de sementes e a realocação de indivíduos. Orchidaceae é a sexta família mais representativa na APA Abaeté, com 15 gêneros e 19 espécies, incluindo Encyclia dichroma e Koellensteinia florida, espécies endêmicas da Mata Atlântica. As características morfológicas mais relevantes na identificação das espécies da área são: tipos de crescimento; volubilidade e espessamento do cauloma; forma e consistência das lâminas foliares; tipo e posição da inflorescência; cor e ressupinação das flores.

Abstract Área de Proteção Ambiental das Lagoas e Dunas do Abaeté (APA Abaeté) is an urban fragment of restinga in an environmentally protected area in the municipality of Salvador, Bahia, Brazil. The area is impacted by irregular disposal of solid waste, clandestine removal of sand from dunes, suppression and fragmentation of original vegetation cover and urban growth of neighborhoods. A recent floristic study revealed new records of orchid species for this conservation unit but highlighted strong threats to the orchid flora. In this context, a taxonomic study of Orchidaceae in APA Abaeté was undertaken with the aim of facilitating the recognition of species in the field and supporting the establishment of more effective local conservation actions for orchids, which should include the manual dispersion of seeds and the relocation of individuals. Orchidaceae is the sixth most represented family in APA Abaeté, with 15 genera and 19 species, including Encyclia dichroma and Koellensteinia florida, endemic species of the Atlantic Forest. The most relevant morphological characteristics for the identification of species in the area are: growth type; climbing habit; caulome thickness; shape and consistency of leaf blades; inflorescence type and position; and color and resupination of flowers.

ABSTRACT Introduction: Digital holographic microscopy has made it possible to incorporate the use of numerical and computer tools into optical microscopy. This in turn has led to great progress in the study of cells and tissues in several fields of medicine and related sciences. Objective: Describe the histological and morphometric characteristics of human thyroid follicles using digital holographic microscopy. Methods: A descriptive cross-sectional histomorphometric study was conducted of human thyroid follicles using a digital holographic microscopy facility. Sample processing was based on inclusion technique by paraffin and hematoxylin-eosin staining. Ten to twelve holographic captures were made per sample, and the double propagation method was used for holographic reconstruction. Estimation was carried out of the area, perimeter, and greatest and smallest diameter of follicles and follicular cavities, and tri-dimensional reconstructions were made of holographic images. Arithmetic mean was determined as the measure of central tendency, and typical or standard deviation as the measure of dispersion. Results: Follicular parameters: area (5 140.31 ± 1 126.71 µm2); perimeter (2 961.54 ± 71.2 µm); greatest diameter (921.17 ± 24.34 µm); smallest diameter (746.67 ± 18.08 µm); epithelial height (7.92 ± 0.96). Follicular cavities: area (3 686.18 ± 1 023.52 µm2); greatest diameter (698.86 ± 19.55 µm); smallest diameter (581.15 ± 13.82 µm). Conclusions: A number of follicular parameters determined by digital holographic microscopy have not been reported by the literature consulted, and they are of interest to the histological study of human thyroid follicles.

RESUMEN Introducción: La microscopía holográfica digital ha permitido a la microscopía óptica hacer uso de herramientas numéricas y computacionales; y esto, a su vez, ha favorecido múltiples avances en el estudio de las células y los tejidos en diferentes campos de la medicina y otras ciencias afines. Objetivo: Describir las características histológicas y morfométricas de los folículos tiroideos humanos con la microscopía holográfica digital. Métodos: Se realizó, desde el punto de vista histomorfométrico, un estudio descriptivo y transversal de folículos tiroideos humanos utilizando una instalación de microscopía holográfica digital. Se empleó la técnica de inclusión en parafina y tinción de hematoxilina-eosina para el procesamiento de las muestras. Se realizaron de 10 a 12 capturas de hologramas por muestra y el método de doble propagación para la reconstrucción de los hologramas. Se calculó el área, el perímetro, el diámetro mayor y menor de los folículos y cavidades foliculares y se realizaron reconstrucciones de imágenes holográficas en tres dimensiones. Se determinó como medida de tendencia central la media aritmética y como medida de dispersión la desviación típica o estándar. Resultados: Parámetros foliculares: área (5140,31 ± 1126,71 µm2); perímetro (2961,54 ± 71,2 µm); diámetro mayor:(921,17 ± 24,34 µm); diámetro menor: (746,67 ± 18,08 µm); altura del epitelio (7,92 ± 0,96). Cavidades foliculares: área (3686,18 ±1023,52 µm2); diámetro mayor: (698,86 ± 19,55 µm) y diámetro menor: (581,15 ± 13,82 µm). Conclusiones: Existen parámetros foliculares, determinados mediante la microscopía holográfica digital, no reportados por la literatura consultada, que resultan de interés en el estudio histológico de los folículos tiroideos humanos.

ABSTRACT Herbaria represent irreplaceable repositories of biodiversity and are used to answer questions about conservation, ecology, systematics, and other sciences. In this sense, we characterize the infrastructure, human resources, and idiosyncrasies of Brazilian herbaria. To achieve this goal, curators were sent a structured and standardized questionnaire to gather information about herbaria. The Brazilian Herbaria Network listed 216 active herbaria in the year 2018, of which 139 answered the questionnaire. These herbaria hold 6,741,469 samples in their collections and more than 39,000 type samples. Most herbaria are in federal universities (40.28 %). Only 24 % of the curators considered that their herbarium is valued by their institutions and 52 % indicated inadequate storage areas. Only nine collections have smoke sensors. Our analysis showed that if an herbarium has an institutional policy the curator is 78 % more likely to consider its herbarium valued. Therefore, it is important for all herbaria to institute their policy. These numbers reflect the difficulty in maintaining herbaria, in many cases cared for only by its curator without institutional recognition and support. Despite recent losses in Brazilian natural history collections, herbaria are still threatened by a lack of basic infrastructure.

Resumo Vanilla palmarum (Orchidaceae) é uma holoepífita obrigatória, amplamente distribuída na América do Sul, e apresenta uma emblemática especificidade com palmeiras. A interação epífita-forófitos foi examinada através da análise de espécimes disponíveis na base de dados do Centro de Referência em Informação Ambiental e em herbários brasileiros. Nós reconhecemos nove espécies hospedeiras de V. palmarum no Brasil: Acrocomia aculeata, Attalea phalerata, Attalea speciosa, Elaeis guineensis, Mauritia flexuosa, Syagrus cearensis, S. coronata, S. schizophylla e S. vagans. Os principais forófitos de V. palmarum são: A. speciosa (Cerrado), A. phalerata (Pantanal), M. flexuosa (Floresta Amazônica) e S. coronata (Caatinga). As futuras ações de manejo devem considerar a associação entre V. palmarum e espécies de palmeiras, visando assegurar a proteção das interações ecológicas.

Abstract Vanilla palmarum is an obligately epiphytic orchid distributed widely throughout South America with emblematic specificity for species of palms. This epiphyte-phorophyte association was examined through the analysis of specimens available via the database of Centro de Referência em Informação Ambiental and from Brazilian herbaria. We recognized nine species as hosts of V. palmarum in Brazil: Acrocomia aculeata, Attalea phalerata, Attalea speciosa, Elaeis guineensis, Mauritia flexuosa, Syagrus cearensis, S. coronata, S. schizophylla, and S. vagans. The most important phorophytes of V. palmarum were found to be A. speciosa (Cerrado), A. phalerata (Pantanal), M. flexuosa (Amazon Forest) and S. coronata (Caatinga). Future management actions must consider the association between V. palmarum and its phorophyte palm species in order to ensure the protection of this ecological interaction.

São apresentados uma chave de identificação específica, descrições e comentários, além de fotos e ilustrações diagnósticas.

Abstract Myrtaceae is represented by 23 genera and 974 species in Brazil, and it is one of the most representative families in the Espinhaço Range. The Serra Geral is one of the mountain ranges that make up Northern Espinhaço and represents a floristic gap in the region. Thus, the main purpose of this work was to produce a floristic inventory and taxonomic study for Myrtaceae in Serra Geral of Licínio de Almeida, Bahia. Nine field trips were carried out between 2012 and 2015, and the collected specimens were processed and housed in ALCB and HUEFS herbaria. Eight genera and 43 species of Myrtaceae were found, amongst which Psidium proved the most diverse genus (14 spp.), followed by Eugenia (10 spp.), Myrcia (8 spp.), Myrciaria (5 spp.) and Campomanesia (3 spp.). Blepharocalyx, Calyptranthes and Plinia are represented by a single species each. Psidium rhombeum and Psidium ganevii are endemic species to Bahia, while Calyptranthes clusiifolia is a new occurrence in the state. This study presents a specific identification key, descriptions and comments, as well as photos and diagnostic illustrations, for each species.

ABSTRACT Floristic inventories focussing on the Espinhaço Range have revealed an extensive diversity for Asteraceae and emphasize the high degree of endemism of its species. This study aims to explore the species-rich Asteraceae through a floristic survey, and by identifying endemic records for the municipality of Morro do Chapéu, Bahia. Samples were collected during six field trips in different phytophysiognomies and approximately 1,400 exsiccatae from the main herbaria collections were examined. Asteraceae in Morro do Chapéu is represented by 18 tribes, 72 genera and 119 species. Eupatorieae and Vernonieae are the most species rich tribes and currently comprise 30 and 28 species, respectively, representing 50 % of the local Asteraceae flora. Baccharis represents the richest genus with seven species, followed by Lepidaploa and Mikania with six species each. Species belonging to Eupatorieae, namely Acritopappus santosii, Acritopappus sp. nov., Lapidia apicifolia, Stylotrichium edmundoi, Scherya bahiensis, Trichogonia tombadorensis and, additionally, a new species of Vernonieae, Stilpnopappus sp. nov., are endemic to the municipality. We provide a checklist and identification key for the species, and report the occurrence of endemism and their importance for the biological conservation.

A descriptive and cross-sectional study of the human cerebellar cortex, from the histomorphometric point of view, was carried out from January to September, 2015, using the digital holographic microscopy installed in the Digital Holography Department of Oriente University in Santiago de Cuba, aimed at making measurings that allowed to establish comparisons with other studies. The calculations showed the thickness of the molecular and granular layers, the area, perimeter, greatest and smallest diameters of the body and Purkinje cells nucleus. Also, holographic images in three dimensions were taken, that facilitated to conclude the existence of certain parameters by means of this procedure, those that had not been notified and are of interest in the histological study of the cerebellar cortex

Se realizó un estudio descriptivo y transversal de la corteza cerebelosa humana, desde el punto de vista histomorfométrico, desde enero hasta septiembre del 2015, con el empleo de la microscopia holográfica digital instalada en el Departamento de Holografía Digital de la Universidad de Oriente en Santiago de Cuba, con vistas efectuar mediciones que permitieran establecer comparaciones con otros estudios. Los cálculos mostraron el grosor de las capas molecular y granulosa, el área, el perímetro, los diámetros mayores y menores del cuerpo y el núcleo de las células de Purkinje. Asimismo, se tomaron imágenes holográficas en tres dimensiones, que posibilitaron concluir la existencia de parámetros determinados mediante este procedimiento, los que no habían sido notificados y que resultan de interés en el estudio histológico de la corteza cerebelosa

Resumo O presente estudo fornece o tratamento taxonômico das espécies de Microlicieae para o município de Mucugê, Chapada Diamantina, Bahia, Brasil. Foram catalogadas 27 espécies distribuídas nos gêneros Microlicia (24 espécies), Lavoisiera (L. harleyi e L. nervulosa) e Trembleya (T. parviflora). Com exceção de M. fasciculata, M. viminalis e T. parviflora, as demais espécies encontradas em Mucugê são endêmicas da Chapada Diamantina. Entre as espécies de Microlicia, quatro foram recentemente descritas e outras quatro ainda necessitam de estudos complementares para sua identificação. Anteras poliesporangiadas foram descritas pela primeira vez para 11 espécies de Microlicia. As espécies de Microlicieae ocupam áreas de campo rupestre em altitudes entre 900-1.500 m, em solos arenosos ou pedregosos, às vezes associadas a cursos d'água.

Abstract This study provides a taxonomic survey of Microlicieae tribe in the Mucugê municipality, Chapada Diamantina, Bahia, Brazil. We identified 27 species belonging to three genera: Lavoisiera (L. harleyi and L. nervulosa), Microlicia (24 species) and Trembleya parviflora. Except for Microlicia fasciculata, M. viminalis and Trembleya parviflora, the others species found in Mucugê are endemic to Chapada Diamantina, Bahia. Among the species of Microlicia, four were recently described, and four others still require further studies for its identification. Polysporangiate anthers were described for the first time for 11 species of Microlicia. The species of Microlicieae are found mainly in rocky field vegetation, between 900-1.500 m altitude, in sandy or rocky soils, sometimes associated to water streams.

Resumo Entre as áreas que são reconhecidas pela carência de inventários florísticos no estado da Bahia, destaca-se a região sudoeste, mais precisamente as áreas que compreendem o Espinhaço Setentrional. O objetivo deste estudo foi realizar o levantamento florístico e taxonômico de Rubiaceae da Serra Geral de Licínio de Almeida (SGLA), Bahia. Foram realizadas dez expedições de campo para coleta entre julho de 2012 e maio de 2015, abrangendo todas as fitofisionomias existentes na área. Os materiais coletados foram processados e depositados nos herbários ALCB e HUEFS. Materiais de referência foram também analisados em visita aos herbários ALCB, CEPEC, HRB, HUEFS, RB, SPF. Foram reconhecidas 43 espécies, distribuídas em 28 gêneros, sendo Declieuxia (5 spp.), Borreria (3 spp.), Cordiera (3 spp.) e Psychotria (3 spp.) os gêneros mais diversos e, seguindo os estudos florísticos prévios na Cadeia do Espinhaço, houve um grande número de gêneros (19) com apenas uma única espécie. Psyllocarpus asparagoides, Psyllocarpus laricoides, Stachyarrhena reflexa são endêmicas da Bahia e Minas Gerais; Declieuxia passerina e Galianthe peruviana são novas ocorrências para a Bahia, e duas espécies (Randia sp. e Staelia sp.) são possivelmente inéditas para a ciência. São apresentados chaves de identificação genérica e específica, descrições, comentários taxonômicos para as espécies, além de fotos e ilustrações.

Abstract One of the areas in Bahia that is known by the lack of floristic inventories is the southwest region, more precisely the area that comprises the septentrional part of the Espinhaço Range. The aim of this study was to carry out a floristic and taxonomic survey of Rubiaceae of the Serra Geral of Licínio de Almeida (SGLA), Bahia. Ten field trips were conducted between July 2012 and May 2015, covering all existing vegetation types in the area. The collected material was processed and deposited at HUEFS and ALCB herbaria. Reference materials were also analyzed in visits to CEPEC, HRB, HUEFS, RB and SPF. A number of 43 species distributed in 28 genera were recognized, with Declieuxia (5 spp.), Borreria (3 spp.), Cordiera (3 spp.) and Psychotria (3 spp.) as the most diverse genera. Following previous floristic studies in the Espinhaço Range, there is alarge number of genera (19) represented by a single species. Psyllocarpus asparagoides, Psyllocarpus laricoides and Stachyarrhena reflexa are endemic to Minas Gerais and Bahia; Declieuxia passerina and Galianthe peruviana are new records for Bahia, and two species are considered new for science (Randia sp. and Staelia sp.). Keys to genera and species identification, descriptions, taxonomic and biologic comments for all species are presented, as well as images and illustrations.
