Escherichia coli productora de toxina Shiga: el desafío de adherirse para sobrevivir / Shiga toxin producing Escherichia coli: the challenge of adherence to survive

Resumen Las cepas de Escherichia coli productoras de toxina Shiga (STEC) son reconocidas como responsables de un alto número de casos de enfermedades de transmisión alimentaria a nivel mundial. Su patogenicidad ha sido vinculada directamente con la actividad de las toxinas (Stx); sin embargo, la habilidad de estas bacterias para colonizar al huésped y otras superficies puede ser esencial para desarrollar su poder patogénico. La gran plasticidad genómica de cepas STEC se infiere de la variabilidad de perfiles de virulencia, con la frecuente emergencia de cepas con nuevos genes, codificados en nuevas islas de patogenicidad vinculadas al metabolismo y la adherencia. La formación de biofilm es un mecanismo espontáneo por el cual las cepas STEC resisten en un ambiente hostil, lo que les permite sobrevivir y, de esa forma, llegar al huésped, a través de los alimentos o de las superficies que están en contacto con ellos. Este mecanismo presenta una alta variabilidad intra e interserotipo y su desarrollo no depende solo de los microorganismos que lo conforman. Factores inherentes al ambiente (pH, temperatura) y la superficie (acero inoxidable, poliestireno) a la que pueden adherirse influyen en la expresión de biofilm. El concepto «una salud¼ implica la interrelación entre los actores de salud pública, animal y ambiental para lograr alimentos inocuos y evitar contaminación cruzada y resistencia a sanitizantes, lo cual pone de manifiesto la necesidad de identificar patógenos emergentes a través de nuevos marcadores moleculares, que detecten cepas STEC portadoras del denominado locus for enterocyte effacement (LEE) o del locus de adherencia y autoagregación (LAA).

Abstract Shiga Toxin-producing Escherichia coli (STEC) is recognized as being responsible for a large number of foodborne illnesses around the world. The pathogenicity of STEC has been related to Stx toxins. However, the ability of STEC to colonize the host and other surfaces can be essential for developing its pathogenicity. Different virulence profiles detected in STEC could cause the emergence of strains carrying new genes codified in new pathogenicity islands linked to metabolism and adherence. Biofilm formation is a spontaneous mechanism whereby STEC strains resist in a hostile environment being able to survive and consequently infect the host through contaminated food and food contact surfaces. Biofilm formation shows intra-and inter-serotype variability, and its formation does not depend only on the microorganisms involved. Other factors related to the environment (such as pH, temperature) and the surface (stainless steel and polystyrene) influence biofilm expression. The «One Health¼ concept implies the interrelation between public, animal, and environmental health actors to ensure food safety, prevent cross-contamination and resistance to sanitizers, highlighting the need to identify emerging pathogens through new molecular markers of rapid detection that involve STEC strains carrying the Locus of Enterocyte Effacement or Locus of Adhesion and Autoaggregation.

Capacidade funcional e fatores associados em idosos insulares: uma revisão sistemática da literatura / Functional capacity and associated factors in island elderly: a systematic review of the literature

Objetivo: o objetivo foi realizar uma revisão sistemática da literatura sobre a capacidade funcional e os fatores associados de idosos residentes em ilhas. Estratégia de pesquisa: a busca ocorreu pela combinação dos descritores "comunicação", "senso de humor e humor como assunto", "atividades cotidianas", "limitação da mobilidade", "autonomia pessoal", "cognição", "ilhas", "idoso" e "idoso de 80 anos ou mais" e dos correspondentes na língua inglesa, nas bases de dados: PubMed, Scopus, Web of Science e Lilacs. Resultados: dos 4761 artigos encontrados, 20 foram selecionados. Fatores individuais, clínicos e os relacionados ao estilo de vida foram identificados. Conclusão: a capacidade funcional de idosos é um fenômeno multifatorial. Poucos artigos são realizados em ilhas e a abordagem do contexto espacial, ambiental dos indivíduos idosos é escassa. Mais estudos com foco nos aspectos ambientais devem ser realizados em ilhas, principalmente nas pequenas em extensão, remotas e com pequenas populações.(AU)

Objective: The objective was to conduct a systematic review of the literature on the functional capacity and associated factors of elderly people living on islands. Research strategy: The search took place by combining the descriptors "communication", "sense of humor and humor as a subject", "daily activities", "limited mobility", "personal autonomy", "cognition", "islands", "elderly" and "elderly aged 80 years or more" and correspondents in the English language, in the databases: PubMed, Scopus, Web of Science and Lilacs. Results: Of the 4761 articles found, 20 were selected. Individual, clinical and lifestyle factors were identified. Conclusion: The functional capacity of the elderly is a multifactorial phenomenon. Few articles are conducted on islands, and the spatial and environmental context of elderly individuals is scarce. More studies focusing on environmental aspects should be carried out on islands, mainly in small ones, remote and with small populations.(AU)

Estado funcional e fatores associados em pessoas idosas residentes na ilha de Fernando de Noronha: um estudo seccional / Functional status and associated factors in older persons living on the island of Fernando de Noronha: a cross-sectional study

Resumo Objetivo Analisar o perfil do estado funcional e os fatores associados em pessoas idosas residentes na Ilha de Fernando de Noronha/Pernambuco, Brasil. Método Tratou-se de um estudo seccional, de caráter analítico, e a coleta de dados foi conduzida entre agosto e outubro de 2019. A população do estudo compreendeu 176 pessoas idosas residentes na ilha. O protocolo de coleta foi aplicado por meio de entrevista para resposta ao questionário de variáveis demográficas, sociais, clínicas e ambientais, e aos instrumentos de avaliação. O estado funcional foi determinado a partir da Análise de Classes Latentes, avaliada pelos protocolos dos domínios: cognição, humor, atividades instrumentais de vida diária, mobilidade e comunicação. Resultados O modelo da análise escolhido possuiu duas classes, nomeadas como: "Boa autonomia e independência" e "Moderada autonomia e dependência parcial". A maioria das pessoas idosas apresentou bom estado funcional e os fatores associados foram: pertencer ao sexo masculino, ser separado ou divorciado, viver sozinho, visitar os amigos ou parentes, ter trabalhado mais de 36 anos, ser alfabetizado, não ter deficiência visual ou auditiva, fazer uso de uma ou duas medicações e ter história de queda. Conclusão O estado funcional das pessoas idosas insulares se apresentou como um fenômeno multifatorial, pois fatores demográficos, sociais e clínicos estiveram associados de forma independente à boa funcionalidade. É importante que a manutenção do estado funcional seja incentivada na implementação de políticas públicas voltadas às especificidades das populações residentes em ilhas.

Abstract Objective To analyze the functional status profile and associated factors in older persons living on Fernando de Noronha Island/Pernambuco, Brazil. Method This was a cross-sectional, analytical study, and data collection was conducted between August and October 2019. The study population comprised 176 older persons living on the island. The collection protocol was applied through an interview to respond to the behavior of demographic, social, clinical and environmental variables, and to the assessment instruments. The functional status was determined from the Analysis of Latent Classes, evaluated by the protocols of the domains: cognition, mood, instrumental activities of daily living, mobility and communication. Results The chosen analysis model had two classes, named as: "Good autonomy and independence" and "Moderate autonomy and partial dependence". Most older persons had good functional status and the associated factors were: being male, being separated or divorced, living alone, visiting friends or relatives, having worked more than 36 years, being literate, not having a visual or hearing impairment, taking one or two medications and having a history of falls. Conclusion The functional status of island older persons was presented as a multifactorial phenomenon, as demographic, social and clinical factors remained independently associated with good functionality. It is important that the maintenance of the functional state is encouraged in the implementation of public policies aimed at the specificities of populations residing on islands.

Effect of pancreatin on acute pancreatitis resulting from L-arginine administration in mice, a morpho-histopathological and biochemical study

Abstract Acute pancreatitis (AP) is a life-unpleasant situation with contradictory and inadequate treatments. In this regard, the present study evaluated the effect of the possible pretreatment of lipase-pancreatin on L-arginine-induced AP. Forty adult mice were selected and divided into five groups: I) control group, II and III) AP groups (i.p.) receiving L-arginine of 2×300 and 2×400 mg/100 g body weight (b.w.), IV) AP (2×300 L-arginine) group + pancreatin (mice were i.p. injected by 350 U-lipase), and V) AP (2×400 L-arginine) group + pancreatin (mice were i.p. injected by 350 U-lipase). All AP groups displayed a significant increase in serum levels of ALT, AST, TBARS, and TNF-alpha compared to the control group. Moreover, pancreatic tissue edema, inflammation, and vacuolization of acinar cells were significantly higher in the untreated L-arginine group compared to the control and pancreatin groups. Conversely, the diameter of pancreatic islets significantly declined after induction of pancreatitis compared with control and pancreatin groups. Pancreatin treatment can be used in pancreatic dysfunction, however, this medicine showed no protective effect against L-arginine-induced AP in the mouse model.

Sociodemographic and Environmental Factors Influencing Acute Respiratory Infections among Under-five Children of Chars (riverine islands) of Tinsukia District, Assam: A Community-based Cross-Sectional Study

Acute respiratory tract infections (ARIs) are a major cause of morbidity and mortality in under?five children worldwide. Assam has around 2500 river islands (locally called Chars/Chaporis) in the Brahmaputra River with socioeconomically deprived inhabitants lacking access to basic health?care facilities. A community?based cross?sectional study was carried out among 380 under?five children living in the Char areas of Tinsukia District to estimate the prevalence of ARI and determine the associated risk factors. The prevalence of ARI among under?five children was found to be 56.32%. Prevalence was significantly higher among children living in Dibru?Saikhowa island, with families having >2 children, belonging to socioeconomic class 5 (modified BG Prasad scale), having a positive history of smoking or ARI in family members, having homes with attached kitchens or using wood for cooking, inadequate ventilation or overcrowding and residences of katcha ghars.

COVID-19 vaccine in the Pacific Islands related to COVAX Facility and bilateral assistance / 国際保健医療

  Vaccines were developed at an unprecedented speed in response to the COVID-19 pandemic. High-income countries, including Japan, recorded high vaccination rates in 2021. However, many low-income countries still recorded low vaccination rates, highlighting a global vaccine disparity.  The COVID-19 Vaccines Global Access Facility (COVAX Facility) is a global risk-sharing framework established to ensure the equitable distribution of COVID-19 vaccines. This paper explains the mechanism of the COVAX Facility and discusses the following aspects: (1) issues related to vaccine supply through the COVAX Facility, and vaccine donation or provision as a means of bilateral assistance; (2) case studies of vaccine supply and the number of vaccines administered in the Pacific Islands; and (3) the state of vaccine support in terms of the island nations’ vulnerability to COVID-19.  COVAX Facility was established in May 2020 and started to supply vaccines to low-income countries in February 2021. The framework also played a significant role as a means of vaccine donation from developed countries having had surplus COVID-19 vaccines to low-income countries when COVAX Facility experienced a shortage of vaccines. However, despite these efforts, COVAX Facility was unable to achieve “equal access” to COVID-19 vaccines.  For instance, vaccine disparities persist among the 14 Pacific Island countries, which continue to face challenges pertaining to land dispersal, narrowness, and remoteness from global markets. On some of these islands, received bilateral assistance and vaccine donations through COVAX Facility have provided the necessary and sufficient vaccines and achieved high vaccination rates. However, in some island countries such as Kiribati, Solomon Islands, and Vanuatu, the vaccine supply is sufficient, but it does not translate into vaccinations being administered actively. Such places are particularly susceptible to vaccine wastage. Furthermore, in Papua New Guinea, a country with low basic health care standards, improving vaccination coverage may be a challenge even if large-scale support of the health care system for COVID-19 would be provided in the short term.  It has been over two years since the detected outbreak of COVID-19. To improve vaccination rates globally, it is necessary to not only provide support in terms of vaccine supply but also to offer mid- to long-term assistance, including support for the establishment of vaccination systems and basic health care services.

The Neuroptera of São Tomé e Principe

ABSTRACT Two new entomological surveys were carried out in the República Democrática de São Tomé e Principe in 2019 (earlier surveys were in 1956 and 2001). Of 16 species of Neuroptera identified, only one, a Mantispidae, appears endemic to the archipelago. Chrysopidae and Hemerobiidae account for the majority of species and individuals collected, concentrated here in plantations and anthropized environments, and known to be widely distributed in Africa and even worldwide. Unusually, the family Coniopterygidae is again absent, this time on natural terrains, confirming its earlier absence in 2001 on anthropized and plantation terrains. The findings and ecological distribution support the hypothesis that Hemerobiidae and Chrysopidae were introduced with cash crop cultivation, some of them as late as the 19th century. Their isolation in island environments is probably too recent to have allowed speciation mechanisms to generate endemic species in São Tomé.

ABSTRACT Objective. The sex ratio, proportion of ovigerous females, length at sexual maturity and fecundity of Grapsus grapsus crabs in the Lobos, Venados and Pajaros islands (southeastern Gulf of California) were analyzed. Materials and methods. Sampling was conducted monthly between March 2011 and February 2012, during the night at low tide. Thirty crabs were collected in a quadrant (25 m2) at each sampling site on each island. cw (mm) and w (g) were determined. The sex ratio and size at sexual maturity (cw50%) were estimated, and for ovigerous females, embryonic stages and fecundity (gravimetric method) were determined. Results. The sex ratio (M:F) was 1:1.3. The average size at sexual maturity (cw50%) was 34.9 mm. The majority of females were ovigerous (71.3%), and 48% of the embryos of ovigerous females were at the red-orange phase. Egg diameter ranged from 1.1 to 5 µm, with an average of 2.05 µm. The mean fecundity was 24339.3 eggs. The maximum and minimum weight of ovigerous females was 69.9 and 15.2 g. Conclusions. The studied characteristics of sex ratio, proportion of ovigerous females, length at sexual maturity and fecundity of G. grapsus, indicate the effective administration and management of this resource in this area.

Área de conservación Guanacaste Echinoderms, North Pacific of Costa Rica / Equinodermos del Área de Conservación Guanacaste, Pacífico Norte de Costa Rica

Introduction: The study of the marine diversity of the North Pacific of Costa Rica began with isolated foreign expeditions in the 1930s and was systematically developed in the mid-1990s by the Center for Research in Marine Sciences and Limnology, Universidad de Costa Rica, as consequence there are now a total of 1 479 reported species in this region. Objective: Present an update to the echinoderm richness of the Guanacaste Conservation Area. Methods: We sampled 25 localities exhaustively and estimated similarity between sites based on the family richness and environmental heterogeneity. Results: We found 61 taxa, which represent 26 % of the echinoderm reported species for the country's Pacific coast. Of these, 43 species are new records for the Guanacaste Conservation Area, and seven for Costa Rica and Central American Pacific coasts. We found three morpho-species that do not match to available descriptions of the Eastern Tropical Pacific echinoderm species. We also found the holothuroid Epitomapta tabogae, and the ophiuroid Ophioplocus hancocki, previously thought endemic to Panama and the Galapagos Islands, respectively. The proximity of the sampled sites and the redundancy of certain families may explain why we did not find important differences among localities. Conclusions: The echinoderm richness of this conservation area is at least 20 % higher than previously reported, reaching similar levels to those in other high diversity sites of the Eastern Tropical Pacific.

Introducción: El estudio de la diversidad marina del Pacífico Norte de Costa Rica inició con expediciones extranjeras aisladas en la década de 1930, y fue desarrollado sistemáticamente a mediados de la década de 1990 por el Centro de Investigaciones en Ciencias del Mar y Limnología de la Universidad de Costa Rica, como consecuencia ahora se reporta un total de 1 479 especies en esta región. Objetivo: Presentar una actualización de la riqueza de equinodermos del Área de Conservación Guanacaste. Métodos: Realizamos muestreos exhaustivos en 25 localidades y estimamos la similitud entre sitios con base en la riqueaza de familias y la heterogeneidad ambiental. Resultados: Encontramos 61 taxa, que representan el 26% de las especies reportadas para la costa pacífica del país. De estas, 43 especies son nuevos registros para el Área de Conservación Guanacaste y siete para las costas de Costa Rica y el Pacífico centroamericano. Tres morfoespecies no coinciden con las descripciones disponibles para las especies del Pacífico Tropical Oriental. Por último, hallamos un ejemplar del holoturoideo Epitomapta tabogae y otro del ofiuroideo Ophioplocus hancocki, considerados endémicos para Panamá y las Islas Galápagos respectivamente. La proximidad entre los sitios muestreados y la redundancia de ciertas familias pueden explicar por qué no se encontraron diferencias entre las localidades. Conclusiones: La riqueza de equinodermos de esta área de conservación es al menos 20% mayor que la reportada anteriormente, alcanzando niveles similares a los de otros sitios de alta diversidad del Pacífico Tropical Oriental.

Estudo de aceitabilidade das intervenções psicológicas via telefone para sobreviventes de cancro dos Açores / Azorean cancer survivors' acceptability of psychological telephone-based interventions

INTRODUÇÃO: As intervenções com recurso à tecnologia têm mostrado ser promissoras para ultrapassar algumas barreiras de acesso aos cuidados dos sobreviventes de cancro de regiões mais isoladas. Os estudos de aceitabilidade e das preferências dos sobreviventes relativamente a estas intervenções são escassos em Portugal e inexistentes nos Açores. OBJETIVOS: Este estudo pretendeu avaliar: i) os comportamentos de procura de ajuda dos sobreviventes de cancro dos Açores e as barreiras à procura de ajuda; e ii) o grau de aceitabilidade e as preferências destes sobreviventes relativamente ao desenvolvimento, implementação e participação numa intervenção psicológica via telefone. MÉTODO: Este estudo envolveu 173 sobreviventes de cancro dos Açores, recrutados num hospital público regional, numa unidade de saúde regional e numa instituição sem fins lucrativos. Recorreu-se a um questionário construído para o efeito, sendo os dados tratados com estatística descritiva. RESULTADOS: O apoio psicológico mostrou-se um comportamento de ajuda aceitável para os sobreviventes, sendo as barreiras à procura de ajuda de índole estrutural/prática e de conhecimento as mais endossadas pelos participantes. A maioria da amostra considerou útil uma intervenção psicológica via telefone, reportando ser provável participar. As sessões com uma duração situada entre os 30 a 45 minutos e com uma periodicidade quinzenal foram os aspetos preferenciais dos participantes. DISCUSSÃO E CONCLUSÃO: Espera-se que os resultados deste estudo possam orientar o desenvolvimento de uma intervenção via telefone que responda flexivelmente às necessidades dos sobreviventes dos Açores e facilite o suporte a prestar-lhes, integrando as suas preferências no desenho de uma intervenção desta natureza.

INTRODUCTION: Technology-based interventions are promising for overcoming some barriers that cancer survivors from isolated regions face in accessing health-care. No studies are exploring the acceptability and preferences concerning these interventions in Portugal and even in the Azores. OBJECTIVES: This study aims to evaluate: i) Azorean cancer survivors' help-seeking behaviors and barriers for seeking help; and ii) survivors' acceptability and preferences concerning development, implementation, and participation in the psychological telephone-based intervention. METHOD: This study included a sample of 173 cancer survivors from the Azores archipelago (Portugal) recruited from a local oncological hospital and health unit. Data were collected through a questionnaire built for this purpose and analyzed with a descriptive statistic. RESULTS: Psychological support was an accepted help-seeking behavior and the structural/practical and knowledge barriers for seeking help were the more endorsed by participants. The majority of the sample considered a psychological telephone-based intervention useful; reporting being likely participating. The length of the sessions ranging from 30 to 45 minutes and fortnightly were the participants' preferences. DISCUSSION AND CONCLUSION: Results may guide the development of a psychological telephone-based intervention for cancer survivors from the Azores, which can respond flexibly to their needs and facilitating the support to provide them, including their preferences when designing an intervention of that nature.

Insect (Hexapoda) diversity in the Oceanic Archipelago of Fernando de Noronha, Brazil: Seasonality and Populational Density of Tabanidae (Diptera) / Diversidade de insetos (Hexapoda) no Arquipélago Oceânico de Fernando de Noronha, Brasil: Sazonalidade e Densidade Populacional de Tabanidae (Diptera)

Abstract: The seasonal population density is informed for two epidemiologically important species of bloodsucking Tabanidae, Tabanus occidentalis Linnaeus and T. pungens Wiedemann, recorded at the Fernando de Noronha archipelago that was never connected to the continent. The two species are widespread in the Neotropical Region, have not been recorded from any other oceanic island, and have most likely been introduced accidentally in the archipelago. Tabanus occidentalis dominated the samples, encompassing 99.6% of the specimens collected in the two local seasons, rainy and dry. Tabanus pungens was rarer, encompassing 0.4% of the specimens collected mainly in the dry season. The tabanids of Fernando de Noronha are able to transmit blood pathogens, bringing risks to the health of the livestock. They also pester the tourists, which brings losses to the local tourist industry. Larvae of both species were already collected in the water lettuce Pistia stratiotes Linnaeus and it is highly recommend that this introduced aquatic plant be removed from the ponds of Fernando de Noronha to control tabanid populations.

Resumo: A densidade populacional e a sazonalidade é informada para duas espécies epidemiologicamente importantes de Tabanidae, Tabanus occidentalis Linnaeus e T. pungens Wiedemann, registradas no arquipélago de Fernando de Noronha, o qual nunca foi conectado ao continente. As duas espécies estão amplamente distribuídas na Região Neotropical, não foram registradas em nenhuma outra ilha oceânica e provavelmente foram introduzidas acidentalmente no arquipélago. Tabanus occidentalis dominou as amostras, englobando 99,6% dos exemplares coletados nas duas estações locais, chuvosa e seca. Tabanus pungens foi mais rara, abrangendo 0,4% dos espécimes coletados principalmente na estação seca. Os tabanídeos de Fernando de Noronha são capazes de transmitir patógenos do sangue, trazendo riscos à saúde do gado. Eles também incomodam os turistas, o que traz prejuízos para a indústria turística local. Larvas de ambas as espécies já foram coletadas na alface d'água Pistia stratiotes Linnaeus e é altamente recomendável que esta planta aquática, introduzida no arquipélago, seja removida das lagoas de Fernando de Noronha para o controle de populações de tabanídeos.

A new breeding colony of the Wedge-rumped Storm-Petrel (Hydrobates tethys kelsalli, Lowe 1925) on Foca Island, extreme Northwestern Peru / Una nueva colonia reproductiva de la golondrinas de tempestad peruana (Hydrobates tethys kelsalli, Lowe 1925) en Isla Foca, norte del Perú

Abstract Breeding colonies of Storm-petrels (family Hydrobatidae) are poorly known and can be difficult to find because they typically nest on islands in crevices and burrows inside caves. In the past decade, some breeding locations of the Wedge-rumped Storm-petrel (Hydrobates tethys kelsalli) have been reported on islands off central Peru and northern Chile. Here we report the northernmost breeding colony of this subspecies from Isla Foca, northern of Peru. In April 2006 we found 28 nests, of which 46% had chicks and 54% had eggs. Nests consisted of small holes in the rock with no nest material used for construction. Nesting season coincided with that of other reproductive zones found on the Peruvian coast. These results contribute to the knowledge of the distribution of reproductive colonies of this subspecies on the Peruvian coast.

Resumen Las colonias reproductoras de golondrinas de tempestad son poco conocidas y difíciles de encontrar debido a que estas especies anidan en grietas, madrigueras y dentro de cuevas ubicadas en islas. En la última década, se reportaron algunos sitios de reproducción de Golondrinas de Tempestad Peruana (Hydrobates tethys kelsalli) en islas cercanas al centro de Perú y norte de Chile. En este trabajo se presenta el hallazgo de la colonia reproductora ubicada más al norte de esta subespecie, en la Isla Foca (noroeste peruano). En abril de 2006 se registraron 28 nidos, de los cuales el 46% tenían crías y el 54% huevos. Los nidos consistían en pequeñas hoyos en la roca sin ningún tipo de material para su construcción. La temporada de anidación coincidió con la de otras zonas reproductivas encontradas en la costa peruana. Estos resultados contribuyen al conocimiento de la distribución de las colonias reproductivas de esta subespecie en la costa peruana.

Catálogo actualizado de las plantas vasculares del Parque Nacional Isla del Coco, Costa Rica

Introducción: La flora de la Isla del Coco ha sido objeto de diversos esfuerzos de recolecta, estudios y publicaciones desde hace más de 300 años, hasta llegar a registrarse 263 especies; no obstante, una exploración reciente permitió determinar que se han presentado muchos cambios nomenclaturales, de clasificación y de incremento de especies desde la última publicación, lo cual hace necesario la publicación de una lista actualizada de especies. Objetivo: Elaborar un catálogo actualizado de las plantas vasculares de la Isla del Coco. Métodos: Mediante la búsqueda y revisión de ejemplares de herbario, publicaciones y recolecta de plantas entre 2016 y 2017, se elaboró una lista actualizada de plantas de la isla. Además, se determinó la riqueza estimada y la calidad del inventario utilizando estimadores de biodiversidad y la proporción de especies de acuerdo a su forma, hábitat epífito y procedencia. Resultados: Se registraron 296 especies de plantas vasculares, en 199 géneros y 82 familias, lo cual representa alrededor de un 80 % de la diversidad esperada según los estimadores utilizados (Chao-1 y ecuación de Clench). Del total, 219 (74%) especies son nativas y 77 (26%) son introducidas. Las especies nativas incluyen angiospermas (53%), helechos (44%) y licófitos (3%) y las introducidas solo angiospermas. Se indican las familias y géneros más diversos y las especies más comunes o abundantes. Se presenta un endemismo del 22% (48 spp.) de la flora nativa, compuesto principalmente por helechos (58%). La flora presenta una alta proporción de especies herbáceas (63%) y una baja representación de especies arborescentes (12%) y de bejucos y enredaderas (8%). También se presenta una alta proporción de epífitas, con un 20% del total de la flora, compuesto mayormente por helechos (69%). Este estudio adicionó 45 nuevas especies a la isla, de las cuales 16 son especies nuevas para la ciencia y endémicas para la isla y ocho son especies introducidas. También se actualizaron o corrigieron 36 nombres de especies en comparación con Trusty et al. (2006). Se proporciona un catálogo de especies con anotaciones. Conclusiones: La flora de la Isla del Coco presenta ciertas particularidades que la distinguen de otras islas oceánicas del Pacífico, en especial por la alta proporción de helechos endémicos y la alta diversidad de este grupo en general y el porcentaje relativamente bajo de endemismo. También es característico la baja diversidad de especies arbóreas, con una alta dominancia de Sacoglottis holdridgei en todos los bosques de la Isla y la alta proporción de especies epífitas, compuesto principalmente por helechos. La proporción de especies introducidas es relativamente baja en comparación con otras islas oceánicas del Pacífico.

Introduction: The flora of Isla del Coco has been the subject of various collection studies and publications efforts for more than 300 years. During these years 263 species were registered; however, there have been nomenclature and classification changes, and an increase of known species since the last publication. Objective: To prepare an updated catalog of the vascular plants of Isla del Coco. Methods: The catalog present here is based on the review of herbarium specimens, publications, and plants collected between 2016 and 2017 by the authors. An updated list of plants on the island was prepared. In addition, the estimated richness and the quality of the inventory were determined through biodiversity estimators and the proportion of species according to their form, epiphytic habitat, and origin. Results: 296 species of vascular plants were registered, corresponding to 199 genera and 82 families, which represents about 80% of the expected diversity according to the estimators used (Chao-1 and Clench equation). Of the total, 219 (74%) species are native and 77 (26%) are introduced. Native species include angiosperms (53%), ferns (44%) and lycophytes (3%), and those introduced are represented only by angiosperms. The most diverse families and genera and the most common or abundant species are indicated. From the native flora, 48 spp. (22%) are endemic, and is mainly composed of ferns (58%). The flora has a high proportion of herbaceous species (63%) and a low representation of arborescent species (12%) and vines (8%). There is also a high proportion of epiphytes (20% of the total flora), mostly composed of ferns (69%). This study added 45 new species records to the island, of which 16 are new species for science and endemic to the island, and eight are introduced species. Thirty-six species names were updated or corrected compared to Trusty et al. (2006). A catalog of species with annotations is provided. Conclusions: The flora of Isla del Coco presents certain peculiarities that distinguish it from other Pacific oceanic islands, especially due to the high proportion of endemic ferns, and the high diversity of this group in general, and the relatively low percentage of endemism. Also, characteristics as the low diversity of tree species, with high dominance of Sacoglottisholdridgei in all the forests of the island, and the high proportion of epiphytic species, mainly composed of ferns. The proportion of introduced species is relatively low, compared to other oceanic Pacific islands.

Tracing the genetic root of Trinket cattle: an endangered cattle population of a small isolated island of Nicobar group of islands

Trinket cattle are the inhabitant of a small island called Trinket, which is one of the picturesque islands of Andaman. This herd is thought to be of Danish leftover during their dynasty in Nicobar archipelago. When the island was abandoned by foreign invaders, indigenes utilized the animals for the purpose of meat. As a result, the cattle became semi-feral in nature. After the Great Sumatra earthquake and tsunami of Indian Ocean in 2004, Trinket island was left abandoned by indigenes and the cattle became totally feral in nature. To trace the genetic root of the cattle, this study has been undertaken based on the sequence information of the mitochondrial D-loop and cytochrome b gene. The genomic DNA was extracted from the blood samples of the Trinket cattle and was used for amplification of mitochondrial markers, and the sequence information was generated by Sanger sequencing. The analysis of sequence information revealed that the Trinket cattle belongs to Bos indicus (I) haplotype, sub-haplotype I2. The presence of I2 sub-haplotype in Trinket cattle may be due to the expansion of this I2 haplotype towards Southeast Asian countries. This is a novel input for the formulation of breeding strategy towards conservation of eco-friendly sustainable livestock in the isolated island ecosystem.

Changes of peripheral and bone marrow erythrocytesin plateau pikasand rats after hypoxia exposure / 中国组织工程研究

BACKGROUND: Changes of red blood cell in peripheral blood and bone marrow erythropoietic system in plateau pikas are of great significance for hypoxic adaptation. OBJECTIVE: To explore the hypoxic adaptation of erythropoietic system in plateau pikas by comparing the morphological changes of peripheral blood and bone marrow between plateau pikas and rats exposed to hypoxia. METHODS: There were 12 healthy wild plateau pikas and 12 clean Sprague-Dawley rats and were randomly divided into experimental and control groups, 6 in each group. The experimental group animals were fed in a simulated 5 000 m altitude hypobaric hypoxia chamber for 28 consecutive days, and the control group animals were fed in the laboratory at 2 260 m altitude. RESULTS AND CONCLUSION: (1) The diameter of the erythrocytes was smaller and red blood cell count was higher in plateau pikas than those in the rats of control group. After 28 days of hypoxia, red blood cell count, hemoglobin and hematocrit were increased in both experimental groups (P < 0.001), but the increased rate of plateau pikas were less than that of the rats. The mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration showed no significant changes in plateau pikas. (2) Results of bone marrow smear showed that the proportion of polychromatic and orthochromatic erythroblasts had no significant changes in plateau pikas after hypoxia, but increased significantly in the rats (P < 0.05). (3) Hematoxylin-eosin staining results of the sternum indicated that the immature erythroblasts islands did not change significantly in plateau pikas, but increased significantly in rats. (4) So the erythroid changes in peripheral blood and bone marrow of plateau pikas before and after hypoxia are significantly lower than those of the Sprague-Dawley rats, and they may be related to the hypoxia adaptation mechanism.

First record of Hirsutella saussurei in the Galápagos Islands and first evidence parasitizing the invasive paper wasp, Polistes versicolor

Abstract In the present work we report the first occurrence of the entomogenous fungus Hirsutella saussurei, in the Galápagos Islands, and also the first evidence of this fungus parasitizing a new host: the invasive paper wasp Polistes versicolor. Some wasps parasitized by the fungus were found in Santa Cruz island in 2018 and 2019, while two new specimens were found in Floreana in 2019. Our data enlarge both the geographical distribution of the fungus and the host range. Even though P. versicolor is considered an important threat for the Galapagos endemic fauna, it is necessary a deep research to know if H. saussurei could be included under control programs of this invasive wasp.

Prevalence patterns of alcohol consumption and factors associated with problematic drinking on remote islands of Okinawa, Japan: a cross-sectional study / Journal of Rural Medicine

Objective: This study aims to investigate the drinking behavior on the remote islands of Okinawa Prefecture.Patients/Materials and Method: This was a cross-sectional study conducted with residents of Okinawa Prefecture’s small, isolated islands. Between October 1 and December 3, 2014, island residents over 20 years of age who visited island clinics for an annual health checkup or influenza vaccination were recruited. An anonymous entry survey was administered to those who provided their consent. The survey included information on age, sex, presence or absence of drinking, age at drinking initiation, smoking status, comorbidities, and family and social background. The Alcohol Use Disorder Identification Test (AUDIT) was used to assess alcohol consumption. Participant characteristics were analyzed descriptively, and logistic regression analysis was conducted to assess relationships between the high-risk drinking group (AUDIT score ≥10 points) and other measured variables (age, sex, age at drinking initiation, smoking, residence, and employment status).Results: Compared to the results of a national survey in 2013, there was a significantly higher prevalence of male island residents who drank ≥40 g of alcohol per day and female island residents who drank ≥20 g/day, levels which are considered risk factors for lifestyle diseases. Among both male and female island residents, there were significantly higher proportions of those with AUDIT scores ≥8 points, referred to as high-risk drinkers, and those with AUDIT scores ≥20, individuals considered to have probable alcohol dependence, as compared to the results of the national survey. In a logistic regression analysis, factors related to high-risk drinking included younger age, male sex, smoking history, inoccupation, and underage drinking initiation.Conclusion: This is the first report on drinking behavior among inhabitants of Okinawa’s remote islands. The degree of alcohol consumption is serious and must be recognized as a regional health problem.
