Population survey of Holothuria (Halodeima) grisea (Aspidochirotida: Holothuriidae) at its limit of geographic distribution in the Western South Atlantic / Estudio poblacional de Holothuria (Halodeima) grisea (Aspidochirotida: Holothuriidae) en su límite de distribución geográfica en el Atlántico Sur Occidental

Abstract Introduction: The sea cucumber Holothuria (Halodeima) grisea Selenka, 1867 is a common echinoderm in intertidal regions along the Brazilian coast, which recently became the focus of unreported and unregulated fisheries. This study was carried out in sandy-rocky substrates at Armação do Itapocoroy, Penha, Santa Catarina (26o47' S; 48o36' W), near its southern limit of geographic distribution. Objective: To determine the densities (individuals*m-2) of Holothuria (H.) grisea within a spatial-temporal perspective as well as to determine biometric and growth characteristics of the population. Methods: Two-meter wide transects perpendicular to the coastline were carried out in winter and spring 2019 and in summer and spring 2020, in periods of spring low-tides. In each sampling occasion the total number of specimens of H. grisea were determined, and a group of 90 organisms was submitted to in situ biometrics (weight, length and width), and immediately returned alive to their habitat. Results: The densities of H. (H.) grisea were significantly higher in the subtidal sector and lower in the upper intertidal sector with no indication of significant differences among sampling campaigns. Depth was the primary factor explaining the observed density patterns and rugosity of the substrate was secondary but also important. The body length ranged from 5.2 to 22.5 cm, whereas the weight varied from 6.0 to 230 g. The mean and modal lengths were 12.54 and 13 cm, respectively. Approximately 75 % of the population sampled was between 10 and 14 cm and the average weight was 60 g. Estimates from von Bertalanffy growth function indicate that the youngest sea cucumber was one year-old, and the oldest had approximately two and a half years. Conclusions: This is the first study to determine biometric parameters for H. (H.) grisea in southern Brazil and the first one to estimate growth and age estimates for a wild population of this species. The densities recorded in the present study were lower than those previously reported for this region, suggesting anthropic influence.

Resumen Introducción: El pepino de mar Holothuria (Halodeima) grisea Selenka, 1867 es un equinodermo común en las regiones intermareales a lo largo de la costa brasileña, que recientemente se convirtió en foco de pesquerías no declaradas y no reguladas. Este estudio se realizó en sustratos arenosos-rocosos en Armação do Itapocoroy, Penha, Santa Catarina (26o47' S; 48o36' W), cerca del límite sur de su distribución geográfica. Objetivo: Determinar las densidades (individuos*m-2) de Holothuria (H.) grisea dentro de una perspectiva espacio-temporal así como determinar las características biométricas y de crecimiento de la población. Métodos: Se realizaron transectos de dos metros de ancho perpendiculares a la línea de costa en invierno y primavera de 2019 y en verano y primavera de 2020, en periodos de bajamar sicigia. En cada ocasión de muestreo se determinó el número total de especímenes de H. (H.) grisea, y se sometió un grupo de 90 organismos a biometría in situ (peso, longitud y ancho), e inmediatamente se los devolvieron vivos a su hábitat. Resultados: Las densidades de H. (H.) grisea fueron significativamente más altas en el sector submareal y más bajas en el sector intermareal superior sin indicios de diferencias significativas entre las campañas de muestreo. La profundidad fue el factor principal que explica los patrones de densidad observados y la rugosidad del sustrato fue secundaria pero también importante. La longitud del cuerpo varió de 5.2 a 22.5 cm, mientras que el peso varió de 6.0 a 230 g. Las longitudes media y modal fueron 12.54 y 13 cm, respectivamente. Aproximadamente el 75 % de la población muestreada midió entre 10 y 14 cm y el peso promedio fue de 60 g. Estimados de la función de crecimiento de von Bertalanffy indican que el ejemplar más joven presentaba un año de edad, mientras el más viejo presentaba cerca de dos años y medio. Conclusiones: Este es el primer estudio que determina parámetros biométricos para una población de H. (H.) grisea en el sur de Brasil y el primero en estimar el crecimiento y edades para una población salvaje de esta especie. Las densidades registradas en el presente estudio fueron inferiores a las reportadas previamente para esta región sugiriendo la ocurrencia de influencia antrópica.

Diversity of fungal endophytes from mangrove plants of Santa Catarina Island, Brazil.

The mangrove ecosystem plays a crucial role in preserving the biodiversity of plants, animals, and microorganisms that are essential for materials cycles. However, the exploration of endophytic fungi isolated from mangroves, particulary in Santa Catarina (SC, Brazil), remains limited. Therefore, the purpose of this study was to assess the biodiversity of endophytic fungi found in Avicennia schaueriana, Laguncularia racemosa, Rhizophora mangle, and Spartina alterniflora from two mangroves on the Island of Santa Catarina: one impacted by anthropic action (Itacorubi mangrove) and the other environmentally preserved (Ratones mangrove). Samplings were carried out between January 2020 and May 2021. Fungi were isolated from leaves, stems, and roots, identified, and clustered into groups through morphological characteristics. Further, a representative strain of each group was identified through ITS1 sequencing. A total of 373 isolates were obtained from plant tissues, of which 96 and 277 isolates were obtained from Itacorubi and Ratones mangroves, respectively. Molecular identification showed that the endophytic fungal community comprised at least 19 genera. The data on fungal community diversity revealed comparable diversity indices for genera in both mangroves. However, we observed differences in the total frequency of fungal genera between impacted (27.38%) and non-impacted (72.62%) mangroves. These findings suggest that anthropic activities in and around the Santa Catarina mangroves have had negative impact on the frequency of endophytic fungi. This emphasizes the reinforcing the significance of preserving these environments to ensure the maintenance of fungal community diversity.

Acute gastroenteritis outbreak associated with multiple and rare norovirus genotypes after storm events in Santa Catarina, Brazil.

Norovirus is a major cause of acute diarrheal disease (ADD) outbreaks worldwide. In the present study, we investigated an ADD outbreak caused by norovirus in several municipalities of Santa Catarina state during the summer season, southern Brazil in 2023. As of the 10th epidemiological week of 2023, approximately 87 000 ADD cases were reported, with the capital, Florianópolis, recording the highest number of cases throughout the weeks. By using RT-qPCR and sequencing, we detected 10 different genotypes, from both genogroups (G) I and II. Some rare genotypes were also identified. Additionally, rotavirus and human adenovirus were sporadically detected among the ADD cases. Several features of the outbreak suggest that sewage-contaminated water could played a role in the surge of ADD cases. Storm events in Santa Catarina state that preceded the outbreak likely increased the discharge of contaminated wastewater and stormwater into water bodies, such as rivers and beaches during a high touristic season in the state. Climate change-induced extreme weather events, including intensified rainfall and frequent floods, can disturb healthcare and sanitation systems. Implementing public policies for effective sanitation, particularly during peak times, is crucial to maintain environmental equilibrium and counter marine pollution.

Sharing of living area and exposure of domestic and wild canids to ticks, Rickettsia parkeri and Rangelia vitalii in the Atlantic Forest of southern Brazil.

Spotted fever caused by the bacterium Rickettsia parkeri, and canine rangeliosis caused by the protozoan Rangelia vitalii, are emerging or re-emerging tick-borne diseases in Brazil, where the main tick vectors are Amblyomma ovale and Amblyomma aureolatum, respectively. In the present study, we evaluated exposure to R. parkeri and R. vitalii infection among domestic (Canis lupus familiaris) and wild (Cerdocyon thous) canids sharing living areas within an Atlantic Forest area of southern Brazil. Four different domestic dogs and three different wild canids were captured. Most of the ticks collected from either domestic or wild canids were identified as A. ovale and A. aureolatum. DNA of R. parkeri was amplified from 14% of the A. ovale specimens. Two domestic dogs and two wild canids were seroreactive to R. parkeri antigens with high endpoint titers (>1024). Rangelia vitalii DNA was detected in two wild canids; one of them was resampled 93 days later, again infected by R. vitalii. We report exposure/infection of domestic dogs and wild canids to R. vitalii and/or R. parkeri-infected ticks in an Atlantic Forest area shared by both canid species, indicating that they also shared the same populations of the tick vectors, A. aureolatum and A. ovale. While A. ovale, A. aureolatum, R. parkeri, R. vitalii and C. thous, are all native to the Atlantic Forest, further studies are needed to evaluate the impact of an exotic canine species - C. lupus familiaris - on the enzootic cycles of R. vitalii and R. parkeri, as well as the possible role of domestic dogs in emergence and re-emergence of R. parkeri-spotted fever in humans and canine rangeliosis, respectively.

Bilateral genital asymmetry in livebearer fishes of the genus Phalloceros Eigenmann, 1907, with description of a new species from coastal drainages of southern Brazil (Cyprinodontiformes: Poeciliidae).

A new species of Phalloceros is described from the Tijucas, Maruim, Aririú, Cubatão do Sul, Rio da Madre, D'Una and Tubarão river basins in southern Brazil. The new species is diagnosed among congeners by the bilateral asymmetry of a hood-like structure located immediately anterior to the urogenital papilla of females. The hood is fused with the urogenital papilla on the right side, but free from the papilla on the left side. This hood is reported for the first time in the genus and is present in six of the 21 valid species of Phalloceros, but its bilateral asymmetry is an exclusive condition of the new species. These species do not constitute a monophyletic group. The new species is likely to be phylogenetically related to P. caudimaculatus, whose females have a symmetrical hood.

Álbum/Relatório das Atividades das Pequenas Irmãs da Divina Providência: registros da assistência médico-social na Região Carbonífera Catarinense, 1955-1957 / Album/Report by the Pequenas Irmãs da Divina Providência: records of social and medical assistance in the coal-producing region of southern Santa Catarina, 1955-1957

Resumo Na primeira metade do século XX, a Região Carbonífera Catarinense passou por um intenso processo de industrialização que impactou diretamente as diferentes formas de vida. Como resultado da exploração do carvão mineral, a região enfrentou uma série de problemas sanitários que dificultavam o próprio processo de acumulação do capital. Diante da incapacidade de o poder público atender às demandas sanitárias, o empresariado local estabeleceu parcerias com congregações religiosas femininas para prestar serviços assistenciais em suas vilas operárias. Como resultado dessa relação, as Pequenas Irmãs da Divina Providência produziram um álbum/relatório, composto por textos, desenhos e fotografias que retratam suas atividades assistenciais, entre 1955 e 1957, em uma das vilas da região.

Abstract During the first half of the twentieth century, the coal-producing region of Santa Catarina state underwent intense industrialization that directly impacted various ways of life; various health problems emerged in the region as a result of coal mining and impeded economic progress. As the government was unable to meet health demands, local businesses established partnerships with female religious orders that provided assistance services in the villages where workers lived. As part of such a partnership, the Pequenas Irmãs da Divina Providência created an album of texts, drawings, and photographs as a report describing their activities from 1955 to 1957 in one such village in the region.

Distribuição de grupos folclóricos em Santa Catarina e sua relação com a colonização do Estado / Distribution of folkloric groups in Santa Catarina and its relation to the colonization of the State / Distribución de grupos folclóricos en Santa Catarina y su relación con la colonización del Estado

O objetivo foi verificar se o histórico de colonização das diferentes regiões de Santa Catarina se reflete na distribuição atual dos grupos folclóricos do estado. Os dados quantitativos foram retirados da listagem fornecida pela Fundação Catarinense de Cultura. Para as informações históricas, foi feita uma revisão bibliográfica. Estão registrados 182 grupos folclóricos distribuídos por 74 cidades. A etnia mais abundante foi a alemã, seguida pela luso-açoriana, e então italiana, gaúcha, de outros países europeus, grupos mistos, afrobrasileiros e outros. Os grupos luso-açorianos se concentram no litoral, o que concorda com o fato de terem sido responsáveis pela colonização mais antiga. Para os alemães e demais europeus, foram geograficamente observadas as duas principais ondas de imigração historicamente registradas: primeiro no nordeste e vale do Itajaí e posteriormente no oeste. Percebeu-se que a distribuição de grupos folclóricos de cada etnia tem relação com o processo de colonização das diferentes regiões.

The objective was to verify if the colonization history of different regions of Santa Catarina is reflected on the current distribution of the folkloric groups of the state. The quantitative data were taken from the list provided by the Fundação Catarinense de Cultura. For the historical information, a bibliographic review was done. There are 182 groups registered, distributed on 74 cities. The most abundant ethnicity was German, followed by Portuguese-Azorean, Italian, gaúcha, other European countries, mixed groups, African-brazilian and others. The Portuguese-Azorean groups concentrate on the coast, what agrees with the fact they were responsible for the oldest colonization. For the Germans and other Europeans, the two main colonization waves historically registered were geographically observed: first on the northeast and Itajaí's valley and after on the west. It was perceived that the distribution of the folkloric groups of each ethnicity is related to the colonization process of the different regions.

Temporal trends in the epidemiology of inflammatory bowel diseases in the public healthcare system in Brazil: A large population-based study.

Background: Population-based data on epidemiology of Inflammatory Bowel Diseases (IBD) in Brazil are scarce. This study aims to define temporal trends of incidence and prevalence rates of Crohn's disease (CD) and ulcerative colitis (UC) in Brazil. Methods: All IBD patients from the public healthcare national system were included from January 2012 to December 2020. Average Annual Percent Change (AAPC) and 95% confidence intervals (CI) were calculated using log-linear regression for incidence and binomial regression for prevalence. Moran's I autocorrelation index was used to analyse clustering of cities by level of prevalence. Findings: A total of 212,026 IBD patients were included. Incidence of IBD rose from 9.4 in 2012 to 9.6 per 100,000 in 2020 (AAPC=0.8%; 95% CI -0.37, 1.99); for UC, incidence increased from 5.7 to 6.9 per 100,000 (AAPC=3.0%; 95% CI 1.51, 4.58) and for CD incidence decreased from 3.7 to 2.7 per 100,000 (AAPC=-3.2%; 95% CI -4.45, -2.02). Prevalence of IBD increased from 30.0 in 2012 to 100.1 per 100,000 in 2020 (AAPC=14.8%; CI 14.78-14.95); for UC, from 15.7 to 56.5 per 100,000 (AAPC=16.0%; CI 15.94, 16.17); for CD from 12.6 to 33.7 per 100,000 (AAPC=12.1% CI 11.95, 12.02). A south-north gradient was observed in 2020 prevalence rates of IBD [I=0.40 (p<0.0001)], CD [I=0.22 (p<0.0001)] and UC [I=0.42 (p<0.0001)]. Interpretation: Incidence of CD is decreasing whereas of UC is increasing, leading to stabilization in the incidence of IBD from 2012 to 2020 in Brazil. Prevalence of IBD has been climbing with 0.1% of Brazilians living with IBD in 2020. Funding: None.

Covid-19 em Santa Catarina: um triste experimento populacional / Covid-19 in Santa Catarina: a sad population experiment

Resumo As dificuldades existentes com o enfrentamento da pandemia em Santa Catarina seguem a mesma trajetória dramática do Brasil, com número crescente de casos e mortes diárias. O estado conta com várias regiões consideradas em risco gravíssimo ou grave. A gestão inicialmente bem-sucedida da pandemia, referenciada como um modelo a ser seguido, pouco a pouco foi perdendo coerência e efetividade, cedendo a pressões advindas de poderes políticos e econômicos, em especial de grandes empresários do estado.

Abstract Difficulties related to the coronavirus pandemic in the state of Santa Catarina reflect the same dramatic trajectory seen in Brazil as a whole, with increasing numbers of cases and daily fatalities. Several regions of this state are considered to be at very serious or severe risk. The initially successful management of the pandemic was cited as a model to be followed, but gradually lost coherence and effectiveness as it yielded to pressure from political and economic powers, particularly large employers in the state.

Covid-19, aspectos gerais e a trajetória do vírus no Estado de Santa Catarina / Covid ­ 19, general aspects and virus trajectory in the State of Santa Catarina

Resumo: Por meio de uma pneumonia de origem desconhecida em Wuhan, na China, deu-se a descoberta do novo Coronavírus. A entrada do vírus no Brasil, provavelmente, se deu em São Paulo e, posteriormente, transmitido para outros Estados do país. No dia 28 de fevereiro de 2020, o Estado de Santa Catarina, Região Sul do Brasil, registrou os 3 primeiros casos de COVID-19. Objetiva-se neste estudo, proporcionar uma visão geral sobre a COVID-19 além de relatar sua trajetória no estado de Santa Catarina entre os meses de fevereiro a maio do ano de 2020. A pesquisa deu-se através da interpretação dos dados obtidos pelos painéis de controle da doença no Estado, além dos comunicados, decretos, publicações oficiais e literatura científica disponível nas principais bases de dados online. Mediante a análise de dados, notou-se que até o dia 31 de maio de 2020, o Estado detinha 2,03% do número total de casos de COVID-19 do país, em relação ao número de óbitos, mesmo que as cidades registrassem o maior número de casos, não registraram o maior número de óbitos. Pode-se dizer que o período de quarentena efetiva no Estado foi de 26 dias a contar da data do primeiro decreto até a liberação das atividades e, após a liberação das atividades e flexibilização da quarentena houve um aumento de 8.883 novos casos em 48 dias. Espera-se que relatos como este fomentem estudos sobre a efetividade das medidas de contenção tomadas e contribuam para o controle de novas pandemias.

Abstract: Through pneumonia of unknown origin in Wuhan, China, the new Coronavirus was discovered. The entry of the virus in Brazil, probably, took place in São Paulo and, later, transmitted to other states of the country. On February 28, 2020, the State of Santa Catarina, South Region of Brazil, registered the first 3 cases of COVID-19. The objective of this study is to provide an overview of COVID-19 in addition to reporting its trajectory in the state of Santa Catarina between February and May of 2020. The research took place through the interpretation of the data obtained by the panels control of the disease in the State, in addition to communications, decrees, official publications, and scientific literature available in the main online databases. Through data analysis, it was noted that until May 31, 2020, the State held 1.5% of the total number of COVID-19 cases in the country, about the number of deaths, even if cities registered the greatest number of cases, did not register the greatest number of deaths. It can be said that the effective quarantine period in the State was 26 days from the date of the first decree until the release of activities and, after the release of activities and relaxation of quarantine, there was an increase of 8,883 new cases in 48 days. The outbreak of the new Coronavirus has brought up a major public health problem worldwide, the numbers of patients have been growing since the first records of this virus and the disease is spreading rapidly. Reports like this are expected to encourage studies on the effectiveness of the containment measures taken and contribute to the control of new pandemics.

Leishmaniose visceral em cães / Visceral leishmaniasis in dogs

Background: Canine visceral leishmaniasis (CVL) is a zoonosis of variable clinical presentation, either in systemic orcutaneous form. Clinical signs include anorexia, ophthalmopathies, and chronic kidney disease. In the state of Santa Catarina, the foci are concentrated in the capital and its adjacencies, in the east side of the state. The objective of this studyis to outline the first three reported cases of CVL in the municipality of Curitibanos, since there are no reports to date inthe region of the mountainous plateau, in the middle west of Santa Catarina.Cases: All dogs were treated at the Veterinary Clinic School of the Federal University of Santa Catarina, Campus Curitibanos. The animals, two males and one female, belonged to the same tutor, resided in Curitibanos, and were attendedbetween 2016 and 2020. In the first case, attended in 2016, the complaint was of eye and skin changes about three monthsago. The animal lived in an urban environment and came from Uruguaiana, Rio Grande do Sul. On physical examination,the animal presented skin peeling, wet and crusty lesions, bloody discharge in the ears and nasal hyperkeratosis, as wellas signs suggestive of uveitis. In this case, euthanasia was carried out. The second case had complaints of respiratory, eyechanges, hyporexia, and polydipsia. The dog was prostrate, dehydrated, with lymphadenomegaly and respiratory disorders, compatible with bacterial pneumonia. Bilateral corneal edema confirmed uveitis. Upon return, the animal remaineddehydrated with enlarged lymph nodes. In the aspiration of the lymph nodes, suggestive forms of Leishmania sp. wereobserved. The recommended confirmatory tests were performed, leading to a definitive diagnosis of CVL. The patientwas treated with miltefosine, but later died. The third case was attended for general evaluation after a positive diagnosisfor CVL during an epidemiological survey of the second case. The animal was alert, tachycardic, and tachypneic with...(AU)

Responses of the zooplankton community to the formation of a small reservoir on the Caveiras River, southern Brazil

We investigated changes in the species richness, abundance, and composition of the zooplankton community in response to the formation of a small reservoir in the Caveiras River, southern Brazil. Zooplankton were collected using a motor-pump and aplankton net (68 μm mesh), with 600 L of water filtered per sample. Sampling occurred during the pre-(April, August, and December 2011) and post-impoundment (July and October 2013, and January 2014) phases of the Caveiras River. We identified 86 taxa in this study, and rotifers were the predominant group. The species richness and abundance of the zooplankton increased after the filling of the reservoir. Furthermore, the zooplankton community showed a clear change in the species composition between the phases before and after the formation of the reservoir, with the emergence of typical planktonic species. Changes in the structure of the zooplankton community were related to changes in limnological characteristics due to the impoundment of the river, mainlyin the availability of food and in the concentration of nutrients.(AU)

Trajectory of serogroups causing Invasive Meningococcal Disease in Santa Catarina state, Brazil (2007-2019)

Abstract The aim of this study was to compare the trajectory of serogroups causing Invasive Meningococcal Disease (IMD) in the Santa Catarina (SC) state with those of whole Brazil. A retrospective analysis of all IMD cases reported from January 2007 to December 2019 was carried out. During the study period, 26,058 IMD cases were registered in Brazil and 644 and in SC state alone. Overall, Brazil showed progressive reduction in cases since 2010, when the meningococcal C conjugate vaccine was introducted on National Immunization Program, while SC showed an increase in total cases since 2013, particularly from serogroups W and C. Serogroups distribution was significantly different between Brazil and SC. The emergence of serogroup W highlights the improved meningococcal surveillance through increased accuracy in identification methods in SC state. This finding is important for discussing recommendations of quadrivalent (ACWY) conjugate vaccines in different geographical areas of Brazil.

Trajectory of serogroups causing Invasive Meningococcal Disease in Santa Catarina state, Brazil (2007-2019).

The aim of this study was to compare the trajectory of serogroups causing Invasive Meningococcal Disease (IMD) in the Santa Catarina (SC) state with those of whole Brazil. A retrospective analysis of all IMD cases reported from January 2007 to December 2019 was carried out. During the study period, 26,058 IMD cases were registered in Brazil and 644 and in SC state alone. Overall, Brazil showed progressive reduction in cases since 2010, when the meningococcal C conjugate vaccine was introducted on National Immunization Program, while SC showed an increase in total cases since 2013, particularly from serogroups W and C. Serogroups distribution was significantly different between Brazil and SC. The emergence of serogroup W highlights the improved meningococcal surveillance through increased accuracy in identification methods in SC state. This finding is important for discussing recommendations of quadrivalent (ACWY) conjugate vaccines in different geographical areas of Brazil.
