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)

Incidence and risk factors of metabolic syndrome in rural community population on islands in Zhejiang province / 中华流行病学杂志

Objective: To estimate the incidence of metabolic syndrome and explore possible risk factors for metabolic syndrome in adults of rural communities in Yuhuan county, Zhejiang province, China. Methods: During June-December, 2018, a follow-up survey was conducted in participants without metabolic syndrome at baseline survey in 2012 to obtain the information collected in questionnaire survey, anthropometric data and laboratory data. The incidence of metabolic syndrome in the participants was estimated, and Logistic regression model was used to explore the risk factors, adjusted risk ratio (aRR) and 95%CI. Results: Among 3 162 participants, 522 new metabolic syndrome cases were identified. The 6-year cumulative incidence rate of metabolic syndrome was 16.5%, and the cumulative incidence rate was higher in women (20.6%) than that in men (12.3%, P<0.001). Those incidence rates were higher in those in jobless, smoking or drinking groups. Being women (aRR=1.96, 95%CI: 1.50-2.58) and family history of hypertension (aRR=1.31, 95%CI: 1.04-1.63) were independent risk factors for metabolic syndrome. Conclusion: The follow up indicated that the incidence of metabolic syndrome was relatively high in rural adults on islands in Zhejiang, and women or those with family history of hypertension were more likely to have metabolic syndrome.

Asociación de tiburones con el Monte Submarino Las Gemelas y primera evidencia de conectividad con la Isla del Coco, Pacífico de Costa Rica / Association of sharks with Las Gemelas Seamount and first evidence of connectivity with Cocos Island, Pacific of Costa Rica

Introducción: Los montes submarinos y las islas oceánicas son conocidos como "puntos calientes" de biodiversidad pelágica, los cuales son utilizados por especies altamente migratorias como corredores biológicos naturales. En el Pacífico Tropical Oriental se han establecido una serie de Áreas Marinas Protegidas (AMPs) cuyo objetivo principal es proteger y manejar los recursos marinos que se encuentran dentro de esta región. Sin embargo, muchas de estas AMPs no incluyen esquemas de protección absoluta, y ninguna cuenta con la capacidad de de proteger a las especies altamente móviles una vez que estas se desplazan fuera de sus límites. Objetivos: El objetivo del presente estudio es dar a conocer la primer evidencia de conectividad entre el Parque Nacional Isla del Coco (PNIC) y el monte submarino Las Gemelas ubicado dentro del Área Marina de Manejo Montes Submarinos (AMM-MS) registrada por un tiburón martillo hembra (Sphyrna lewini). Métodos: Entre mayo del 2015 y mayo del 2016 un tiburón martillo y un tiburón zorro (Alopias pelagicus) fueron marcados (V16, Vemco Ltd.) y monitoreados por una serie de receptores acústicos ubicados en el PNIC y en Las Gemelas. Los datos fueron analizados descriptivamente y se calculó el índice de residencia (IR). Resultados: S. lewini realizó viajes de ida y vuelta entre los sitios ubicados dentro del PNIC y el AMM-MS. El mayor número de detecciones registradas por S. lewini ocurrieron en Roca Sucia, y todas las detecciones tuvieron lugar durante las horas de la mañana (7:00 - 12:00 h). S. lewini exhibió una baja residencia (IR=0.02) y una presencia periódica en el área de estudio. Se detectó la presencia de A. pelagicus en Las Gemelas casi un año después de haber sido marcado en ese mismo lugar. Conclusiones: La presencia periódica de S. lewini entre estas dos AMPs, y la presencia de A. pelagicus en Las Gemelas sugiere que los movimientos entre las islas oceánicas de la región puede ser más complejo que simples movimientos de "ida y vuelta", donde los montes submarinos juegan un papel importante en el desplazamiento de dichas especies. Nuestros resultados destacan la importancia de aumentar la protección a los montes submarinos y de crear corredores marinos que conecten las islas oceánicas con el fin de promover la conservación de especies altamente migratorias. Aunque la creación de AMPs alrededor de estas formaciones geológicas se ha propuesto como una manera efectiva de conservar y proteger la biodiversidad marina en aguas abiertas, su efectividad es solo parcial. Esta investigación resalta la importancia de estudiar la dinámica espacial de especies altamente migratorias con el objetivo de mejorar el diseño y la efectividad de AMPs ubicadas lejos del continente como es el caso del PNIC y el AMM-MS.

Introduction: Seamounts and oceanic islands are known as hotspots of pelagic biodiversity, which highly migratory species use as natural biological corridors. Although marine protected areas have been established in the Eastern Tropical Pacific with a goal to protect and manage region's marine biodiversity, not all utilize or enforce a no-take policy, and none are capable of protecting highly mobile species once they move outside of the limit of these areas. Objective: We present the first evidence of shark connectivity between Cocos Island National Park (CINP) and Las Gemelas seamount located in the Seamounts Marine Management Area (SMMA), by a female scalloped hammerhead shark (Sphyrna lewini). Methods: Between May 2015 and May 2016 a scalloped hammerhead shark and a pelagic thresher shark (Alopias pelagicus) were tagged (V16, Vemco Ltd.) and monitored by an array of acoustic receivers installed at CINP and Las Gemelas. We analyzed the acoustic data descriptively and we calculated the residency index (IR). Results: S. lewini performed persistent movements between these two marine protected areas. All detections in Cocos Island occurred during the morning (7:00-12:00 h) and Roca Sucia was the most visited site. The shark shows a low residency (IR=0.02) and intermittent presence in the study area. We recorded the presence of A. pelagicus at Las Gemelas almost one year after it was tagged at the site. Conclusions: The persistent movements of S. lewini between these two pelagic marine protected areas, and the presence of a tagged A. pelagicus at Las Gemelas seamount, suggests that movements between oceanic islands in the region may be more complex than simple "back and forth" movements, with seamounts in between them acting as stepping stones, where they may also stay for periods of time. Our results emphasize the importance of granting greater protection to seamounts and creating connecting swimways to oceanic island hotspots for the conservation of pelagic and highly migratory species. Although the establishment of marine reserves around oceanic islands and seamounts have been proposed as an effective way to conserve and protect marine biodiversity in the high seas, their effectiveness is only partial. This study highlights the importance of studying the spatial dynamics of highly migratory species to help improve the design and efficiency of marine protected areas located in the high seas such as CINP and SMMA.

Composición, densidad y distribución de los poliquetos planctónicos (Phyllodocida: Tomopteridae) en el Domo Térmico de Costa Rica, Pacífico Tropical Oriental / Composition, density and distribution of Tomopteridae, Polychaeta, in the Costa Rica Thermal Dome, Eastern Tropical Pacific

Introducción: Los tomoptéridos son poliquetos holopelágicos ampliamente distribuidos en todos los océanos, sin embargo, han sido pobremente estudiados, a pesar de sus importantes implicaciones en las redes tróficas como depredadores de varios grupos de animales de la comunidad del plancton, incluyendo huevos y larvas de peces. Objetivo: Describir la estructura de la comunidad de estos gusanos pelágicos en un área de surgencia en el Pacífico oriental centroamericano. Métodos: Las muestras de zooplancton fueron obtenidas durante la campaña oceanográfica "DOMO IV" organizada por la Universidad Nacional Autónoma de México en julio-agosto de 1982. Los poliquetos de la familia Tomopteridae fueron separados e identificados, aportando datos de su composición específica, abundancia y distribución. Resultados: Se determinaron cuatro especies del género Tomopteris siendo T. elegans y T. planktonis dominantes, T. nationalis constante y T. euchaeta rara. Tomopteris nationalis, T. elegans and T. euchaeta tienen afinidades tropical y subtropical, mientras que T. planktonis ha sido considerada como una especie cosmopolita. Tomopteris elegans presento la abundancia relativa mayor (62%) y T. euchaeta la menor (2.5). Conclusión: En general, T. elegans y T. planktonis mostraron un notable incremento en su abundancia relacionado con la región de la surgencia en el domo térmico de Costa Rica.

Introduction: The tomopterids are holopelagic polychaetes widely distributed in all oceans, nevertheless they have been poorly studied despite their important implications in the trophic webs, as predators of various groups of zooplankton, including eggs and fish larvae. Objective: To describe the structure of the community of these pelagic worms in an upwelling area in the Central American Pacific. Methods: The zooplankton samples were obtained during the oceanographic campaign DOMO IV organized by the Universidad Nacional Autónoma de Mexico, in July-August, 1982. The polychaetes of the Tomopteridae family were sorted out and identified providing data on their specific composition, abundance and distribution. Results: Four species of the genus Tomopteris were determined, being T. elegans and T. planktonis dominant, T. nationalis constant and T. euchaeta rare. T. nationalis, T. elegans and T. euchaeta have tropical and subtropical affinies, while T. planktonis have been considered as cosmopolitan species. T. elegans had the higher relative abundance (62%) and T. euchaeta the lower (2.5%). Conclusion: Overall, T. elegans and T. planktonis showed a notable rise in the abundance related to upwelling in the thermal dome of Costa Rica.

Community structure of coral reef zooplankton in Isla del Coco National Park, a natural World Heritage site in the Eastern Tropical Pacific / Estructura de la comunidad de zooplancton en arrecifes coralinos del Parque Nacional Isla del Coco, sitio Patrimonio de la Humanidad en el Pacífico Tropical Oriental

Introduction: Zooplankton is a major link between primary producers and the following trophic levels, and in coral reefs they represent an energy source for corals and involve complex assemblies integrating a wide variety of species form different functional groups. Objective: To define interannual changes in zooplankton assemblies in coral reefs of Isla del Coco. Methods: Three coral reefs system were sampled. Two or three samples were taken by surface horizontal trawls in each coral reef from 2009 to 2012, using conical zooplankton nets of 200 and 500 µm mesh sizes at different times of the day. Physical and chemical variables were measured before zooplankton sampling. Results: We identified 24 taxonomic groups of macrozooplankton and 22 of mesozooplankton. Copepods were the most abundant taxa (87.1%) of the total abundance of mesozooplankton and macrozooplakton (58.9%); however, chaetognaths (35.6%) exceeded copepods (35.4%) in abundance in macrozooplankton samples during 2011. Mesozooplankton samples showed higher abundance (68753.2±9123.2 ind m-3) and biomass (85.14±11.3 mg DW m-3) than macrozooplankton samples (4454.9±751.0 ind m-3, 22.8±3.8 mg DW m-3). The interannual macrozooplankton community structure did not change significantly (ANOVA, p=0.368), but did change for mesozooplankton (ANOVA, p=0.001). Variations in physical and chemical variables influenced the community structure for both meso and macrozooplankton, increasing or decreasing organism abundance. Conclusions: Coral reef zooplankton of Isla del Coco resembles that of other coral reefs under the influence of oceanic conditions, with a fauna formed mainly by calanoid copepods, chaetognaths and appendicularians, and depending on oceanographic conditions, the abundance of these groups can change.

Introducción: El zooplancton es el principal enlace entre los productores primarios y los siguientes niveles de la cadena trófica, en los arrecifes de coral representa una importante fuente de alimento, en estos ambientes comprende una amplia variedad de especies de diferentes grupos funcionales. Métodos: En el presente trabajo se analiza la estructura de la comunidad del zooplancton asociado a los sistemas arrecifales de la Isla del Coco, sus variaciones interanuales y como las variables físicas y químicas en diferentes épocas influencian la composición de especies. Las muestras se colectaron sobre los parches de arrecife de Bahía Weston, Bahía Wafer y Bahía Chatham en el sector norte de la Isla, en cuatro periodos, en 2009 a 2012, se realizaron arrastres horizontales con redes cilindro cónicas de 200 y 500 µm tamaño de poro, durante tres e cinco minutos respectivamente a diferentes horas del día. Resultados: Se identificaron 24 grupos taxonómicos dentro del Macrozooplancton y 22 dentro del Mesozooplancton. Mayores abundancias y biomasas se registraron en el Mesozooplancton. Copépodos, apendicularias e quetognatos fueron los grupos más abundantes, siendo afectadas sus abundancias por las variaciones en las variables físicas y químicas. Conclusiones: La comunidad zooplanctónica de los arrecifes coralinos en la Isla del Coco es semejante a aquellos sistemas arrecifales de zonas oceánicas bajo la influencia de aguas oceánicas, con una fauna conformada principalmente por copépodos, quetognatos y apendicularias y que dependiendo de las características oceanográficas imperantes las abundancias de estos grupos pueden cambiar.

Nocturnal variation of the zooplankton community in coral reef substrates at Isla del Coco National Park (Eastern Tropical Pacific) / Variación nocturna del zooplancton en diferentes sustratos de un arrecife coralino de la Isla del Coco, Pacífico Oriental Tropical

Introduction: Zooplankton is a major link in coral reef food webs and a source of nutrients for corals. Demersal zooplankton in coral reefs makes diel migrations at night to avoid predation by fish and corals, increasing abundance and biomass at night. Objectives: To study the composition and variation of the demersal and pelagic zooplankton community at night and to increase the taxonomic knowledge of the benthic copepod fauna over different substrates of a coral reef. Methods: Traps made of plastic, with a 100 μm mesh size collector cup attached, were placed for 12 hours between 5-10 m depth over four substrates: (1) sand, (2) small and (3) big colonies of Porites lobata, and (4) dead and alive corals. Sampling started at dusk (1800 h), and the collector cups were collected and replaced at 2100 and 0000, and the last samples removed at down (0600 h). Results: The highest abundance of zooplankton was capture over P. lobata colonies between 0000 to 0600 h. Copepods (adults, copepodites, and nauplii) dominated the community structure and were more abundant during all the time intervals and substrates. Pelagic copepods were more abundant than the benthic, however, not more diverse. Among the benthic copepods, 20 new records of harpacticoids and calanoids were registered for Isla del Coco and Costa Rican waters. Appendicularians and decapod larvae were also abundant. Changes in coral reef community structure were related with time and not with the kind of substrate, although some taxa were found only in a specific time interval or substrate. Conclusions: Community structure and abundance of demersal and pelagic coral reef zooplankton in Chatham Bay were dominated by copepods, larvaceans and decapod larvae, similar to other coral reefs around the world. The highest abundance peak of organisms in the water column between 0000 to 0600 h could be related to diel migration.

Introducción: El zooplancton demersal en los arrecifes de coral diariamente realiza migraciones diarias durante la noche para evitar ser depredados, su abundancia y su biomasa aumentan durante la noche. Objetivos: Registrar la composición y la variación del zooplancton pelágico-demersal durante la noche y aumentar el conocimiento taxonómico de la fauna de copépodos bénticos sobre diferentes sustratos de un arrecifes de coral. Métodos: El zooplancton asociado a diferentes sustratos fue colectado usando trampas en forma de cono confeccionadas con una bolsa plástica y un copo colector de zooplancton de 100 μm, las trampas se ubicaron sobre cuatro tipos de sustratos en un arrecife de coral: (1) arena, (2) colonias pequeñas y (3) grandes de Porites lobata, y (4) coral vivo y muerto ubicadas entra 5 y 10 m de profundidad. El muestreo fue realizado durante 12 horas, las trampas fueron colocadas a las 1800 h y los copos colectores se cambiaron a las 2100, 0000 y 0600 h. Resultados: Los copépodos (adultos, copepoditos y nauplios) dominaron la composición y fueron más abundantes en todos los intervalos de tiempo y cada uno de los sustratos. Los copépodos pelágicos fueron más abundantes pero no más diversos que los bentónicos. Dentro de los copépodos bénticos recolectados, 20 nuevos registros fueron identificados para las aguas de la Isla del Coco y Costa Rica. Los cambios en la estructura de la comunidad del zooplancton de los arrecifes de coral se relacionaron con el intervalo tiempo de muestreo y no con el tipo de sustrato en que fue colocado la red. Conclusiones: La composición de la comunidad y la abundancia de zooplancton pelágico-demersal en los arrecifes de coral de Bahía Chatham fueron dominadas por copépodos, larvaceos y larvas de decápodos, similar a otros arrecifes de coral alrededor del mundo. El intervalo de tiempo con la mayor abundancia de organismos fue el de 0000 a 0600 h, este pico de abundancia puede estar relacionado con la migración vertical.

Simulación de oleaje en los alrededores de la Isla del Coco, Costa Rica / Numerical simulation of wave field around Cocos Island, Costa Rica

Introducción: La Isla del Coco por su ubicación en el océano Pacífico y en aguas profundas, periódicamente arriban olas energéticas que se originan en el Océano del Sur. La isla actúa como un abrigo disipando parte de la energía de las olas que llegan a la costa pacífica de Costa Rica. Objetivo: El objetivo del trabajo es caracterizar las condiciones generales del oleaje a través de la simulación numérica del oleaje en el Pacífico Tropical del Este (PTE), con especial interés en la Isla del Coco. Métodos: Las olas se propagan con el modelo espectral de oleaje WAVEWATCH III. Se usa en el modelo una malla no estructurada. Se utilizan dos años (2007-2008) de datos históricos de oleaje como condiciones de frontera obtenidos de reanálisis con el modelo WAVEWATCH generado por el Instituto Francés para la Investigación del Mar (IFREMER por sus siglas en francés). Se obtienen mapas anuales y estacionales y series temporales de la altura significante de la ola, periodo y dirección asociado al pico del espectro de energía. Resultados: Los resultados mostrados son similares a otros estudios previos de simulación y observación. El campo de oleaje es caracterizado por periodos largos y dirección desde suroeste en promedio. Las condiciones de oleaje sobre la isla obedecen a los sistemas extratropicales de ambos hemisferios y a procesos locales en el PTE. Conclusiones: El modelo de olas WAVEWATCH III mostró que representa las condiciones típicas de oleaje en los alrededores de la Isla del Coco. Es el primer trabajo de simulación de oleaje aplicando una malla no convencional en la zona económica exclusiva de Costa Rica. El estudio sirve como base para extenderse a otras áreas específicas de la costa.

Introduction: Periodically energetic waves, originated in the Southern Ocean, arrive to Cocos Island, because of its location in the Pacific Ocean and in deep waters. The island acts as a shelter dissipating part of the energy of the waves that reach the Pacific coast of Costa Rica. Objetive: The objective of the work is to characterize the general conditions of the swell through the numerical simulation of the swell in the Eastern Tropical Pacific (ETP), with special interest in Cocos Island. Methods: The waves are propagated with the WAVEWATCH III wave spectral model. An unstructured mesh is used in the model. Two years (2007-2008) of hindcast data are used as boundary conditions obtained from reanalysis with the WAVEWATCH model, generated by the French Institute for Marine Research (IFREMER for its acronym in French). Annual and seasonal maps and time series of significant wave height, peak period and peak wave direction are obtained. Results: The results shown are similar to other previous simulation and observation studies. The mean wave field is characterized by long periods from southwest direction. The wave conditions on the island obey the extratropical systems of both hemispheres and local processes in the PTE. Conclusions: The WAVEWATCH III wave model showed that it represents the typical wave conditions in the surroundings of Cocos Island. It is the first wave simulation work applying an unconventional mesh in the exclusive economic zone of Costa Rica. The study serves as a basis for extending to other specific areas of the coast.

Immediate regraft of the remnant skin on the donor site in split-thickness skin grafting

BACKGROUND: Skin defects of head and neck need reconstruction using various local flaps. In some cases, surgeons should consider skin graft for large skin defect. It is important to heal skin graft and donor sites. The authors investigated wound healing mechanisms at the donor sites with split-thick-ness skin graft (STSG). In this study, the authors compared two types of immediate regraft including sheets and islands for the donor site after facial skin graft using remnant skin. METHODS: The author reviewed 10 patients who underwent STSG, from March 2015 to May 2017, for skin defects in the craniofacial area. The donor site was immediately covered with the two types using remnant skin after harvesting skin onto the recipient site. Depending on the size of the remnant skin, we conducted regraft with the single sheet (n= 5) and island types (n= 5). RESULTS: On postoperative day 1 and 3 months, the scar formation was evaluated using the Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS). Total POSAS and VSS scores for the island type were lower than in single sheet group after 3 months postoperatively. There was significant difference in specific categories of POSAS and VSS. CONCLUSION: This study showed a reduction in scar formation following immediate regrafting of the remnant skin at the donor site after STSG surgery. Particularly, the island type is useful for clinical application to facilitate healing of donor sites with STSG.

Blood transcriptome resources of chinstrap (Pygoscelis antarcticus) and gentoo (Pygoscelis papua) penguins from the South Shetland Islands, Antarctica

The chinstrap (Pygoscelis antarcticus) and gentoo (P. papua) penguins are distributed throughout Antarctica and the sub-Antarctic islands. In this study, high-quality de novo assemblies of blood transcriptomes from these penguins were generated using the Illumina MiSeq platform. A total of 22.2 and 21.8 raw reads were obtained from chinstrap and gentoo penguins, respectively. These reads were assembled using the Oases assembly platform and resulted in 26,036 and 21,854 contigs with N50 values of 929 and 933 base pairs, respectively. Functional gene annotations through pathway analyses of the Gene Ontology, EuKaryotic Orthologous Groups, and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases were performed for each blood transcriptome, resulting in a similar compositional order between the two transcriptomes. Ortholog comparisons with previously published transcriptomes from the Adélie (P. adeliae) and emperor (Aptenodytes forsteri) penguins revealed that a high proportion of the four penguins’ transcriptomes had significant sequence homology. Because blood and tissues of penguins have been used to monitor pollution in Antarctica, immune parameters in blood could be important indicators for understanding the health status of penguins and other Antarctic animals. In the blood transcriptomes, KEGG analyses detected many essential genes involved in the major innate immunity pathways, which are key metabolic pathways for maintaining homeostasis against exogenous infections or toxins. Blood transcriptome studies such as this may be useful for checking the immune and health status of penguins without sacrifice.

Current Status of Parasite Infections in Indonesia: A Literature Review

Indonesia and South Korea have become inseparable in various respects since the 2 countries established diplomatic relation in 1973. Indonesia is a tropical region that stretches across the equator, comprised of 5 main islands (Java, Kalimantan, Sumatra, Sulawesi, and Papua) and 4 archipelagoes (Riau, Bangka Belitung, Nusa Tenggara, and Maluku). As most population of Eastern Indonesia (Sulawesi, Papua and Nusa Tenggara & Maluku) live in poor areas, it is expected that there will be many parasites. Nevertheless, little is known about the status of parasites in Indonesia. This study examines the prevalences of malaria and lymphatic filaria, which are prevalent in Indonesia, as well as those of soil-transmitted-helminths (STH). As a result, the Plasmodium falciparum and P. vivax case loads are almost equal. The current prevalence of P. vivax is uniformly low (<5%) in all age groups and annual parasite incidence (API) showed decreasing tendency as 0.84 per 1,000 population in 2016. However, more than 65 million people still live in malaria epidemic regions. Lymphatic filariasis remains an important public health problem and 236 cities were classified as endemic areas in 514 cities/districts in 2017. It is difficult to ascertain the current prevalence rate of STH in Indonesia, although West Sumba and Southwest Sumba in East Nusa Tenggara reported prevalence rate of more than 20%. The study also considers the (sero) prevalences of other parasites identified in Indonesia. This report should be useful not only to parasitologists but also to travelers and people with business in Indonesia.

Survey of Gymnophalloides seoi Metacercariae in Natural and Cultured Oysters from Several Western Coastal Areas, Korea

Gymnophalloides seoi (Digenea: Gymnophallidae) is a human intestinal trematode contracted by eating raw oysters (Crassostrea gigas) in the Republic of Korea (=Korea). It has been known to be highly endemic in Aphae Island, Shinan-gun, Jeollanam-do (Province). However, recent epidemiological status of G. seoi has not been reported since the 1990s. In this study, we investigated the prevalence of G. seoi metacercariae in natural and cultured oysters collected from 3 islands and 2 coastal areas in western parts of Korea. The oysters were examined using the artificial digestion method followed by stereomicroscopy. The overall positive rate of G. seoi metacercariae in natural oysters was 66.0% (99/150), and the oysters collected from Yubu Island showed the highest infection rate (74.0%). However, the metacercarial density per oyster was relatively low (1.5–2.4 per oyster). By contrast, no metacercaria was found in cultured oysters purchased from 2 coastal areas in Chungcheongnam-do. Thus, we could confirm that natural oysters produced from 3 western coastal islands are infected with G. seoi metacercariae, whereas cultured oysters purchased from 2 coastal areas were free from infection.

Cancer-Associated Fibroblasts and Desmoplastic Reactions Related to Cancer Invasiveness in Patients With Colorectal Cancer

PURPOSE: We evaluated the relationship of cancer-associated fibroblasts (CAFs) and desmoplastic reactions with cancer invasiveness and long-term outcomes in patients with colorectal cancer (CRC). METHODS: Histologic evaluation of mature CAFs and desmoplasia was performed by observing the collagen fiber structure and fibroblast cytomorphology in the intratumoral stroma and invasive front of CRC tissues. Cancer-cell invasiveness was evaluated using lymphatic invasion, vascular invasion, perineural invasion, tumor budding, and tumor growth patterns. Overall survival and systemic recurrence were analyzed. A network analysis was performed between CAF maturation, desmoplastic reaction, and cancer invasiveness. RESULTS: The proportions of mature CAFs in the intratumoral stroma and the invasive front were 57.6% and 60.3%, respectively. Epidermal growth factor receptor (EGFR) overexpression was significantly higher in the mature CAFs in the invasive front as compared to immature CAFs. Lymphatic invasion increased as the number of mature fibroblasts in the intratumoral stroma increased. Tumor budding was observed in almost half of both mature and immature stroma samples and occurred more frequently in infiltrating tumors. On network analysis, well-connected islands were identified that was associated with EGFR overexpression, CAF maturation, and infiltrating tumor growth patterns leading to tumor budding. CONCLUSION: The maturity of CAFs and desmoplastic reactions were associated with cancer invasion. However, the cytomorphologic characteristics of CAFs were insufficient as an independent prognostic factor for patients with CRC.

Phylogenetic MLSA and phenotypic analysis identification of three probable novel Pseudomonas species isolated on King George Island, South Shetland, Antarctica

ABSTRACT Antarctica harbors a great diversity of microorganisms, including bacteria, archaea, microalgae and yeasts. The Pseudomonas genus is one of the most diverse and successful bacterial groups described to date, but only eight species isolated from Antarctica have been characterized. Here, we present three potentially novel species isolated on King George Island. The most abundant isolates from four different environments, were genotypically and phenotypically characterized. Multilocus sequence analysis and 16S rRNA gene analysis of a sequence concatenate for six genes (16S, aroE, glnS, gyrB, ileS and rpoD), determined one of the isolates to be a new Pseudomonas mandelii strain, while the other three are good candidates for new Pseudomonas species. Additionally, genotype analyses showed the three candidates to be part of a new subgroup within the Pseudomonas fluorescens complex, together with the Antarctic species Pseudomonas antarctica and Pseudomonas extremaustralis. We propose terming this new subgroup P. antarctica. Likewise, phenotypic analyses using API 20 NE and BIOLOG® corroborated the genotyping results, confirming that all presented isolates form part of the P. fluorescens complex. Pseudomonas genus research on the Antarctic continent is in its infancy. To understand these microorganisms' role in this extreme environment, the characterization and description of new species is vital.

Malignant pilomatricoma of the cheek in an infant

Malignant pilomatricoma (pilomatrical carcinoma) is a rare, locally occurring malignant tumor with a high rate of recurrence in the case of incomplete excision. This tumor has two characteristics. First, recurrences of pilomatrical carcinoma are common; second, distant metastasis is rare, but if it occurs, it is very fatal. It has characteristic features of high mitotic counts, cellular atypia, and local invasion. Although fine needle aspiration and excisional biopsy could help to confirm this tumor diagnosis, pathologic findings are critical. Pilomatricomas have some characteristic features in histological aspect, such as epithelial islands of basaloid cells and shadow cells or ghost cell. Also, various types of immunohistochemical staining are used to confirm the diagnosis. Despite the lack of clear surgical criteria, treatment is a wide local excision with histologically clear resection margins with or without adjuvant radiotherapy.

Packaging of Rift Valley fever virus pseudoviruses and establishment of a neutralization assay method

Rift Valley fever (RVF) is an acute, febrile zoonotic disease that is caused by the RVF virus (RVFV). RVF is mainly prevalent on the Arabian Peninsula, the African continent, and several islands in the Indian Ocean near southeast Africa. RVFV has been classified by the World Organisation for Animal Health (OIE) as a category A pathogen. To avoid biological safety concerns associated with use of the pathogen in RVFV neutralization assays, the present study investigated and established an RVFV pseudovirus-based neutralization assay. This study used the human immunodeficiency virus (HIV) lentiviral packaging system and RVFV structural proteins to successfully construct RVFV pseudoviruses. Electron microscopy observation and western blotting indicated that the size, structure, and shape of the packaged pseudoviruses were notably similar to those of HIV lentiviral vectors. Infection inhibition assay results showed that an antibody against RVFV inhibited the infective ability of the RVFV pseudoviruses, and an antibody neutralization assay for RVFV detection was then established. This study has successfully established a neutralization assay based on RVFV pseudoviruses and demonstrated that this method can be used to effectively evaluate antibody neutralization.

Prevalence of Escherichia coli Carrying pks Islands in Bacteremia Patients

Escherichia coli can harbor genomic pks islands that code for a polyketide-peptide genotoxin known as colibactin. E. coli strains carrying pks islands trigger genetic instability. pks islands have been significantly associated with bacteremia. We investigated the molecular epidemiology of bacteremic E. coli isolates and the prevalence of bacteremia-causing E. coli carrying pks islands. A total of 146 E. coli isolates were collected at a tertiary-care hospital from January 2015 to December 2016. The phylogenetic groups were determined by multiplex PCR. All isolates were screened by PCR for sequence type 131 (ST131)-associated single-nucleotide polymorphisms (SNPs) in mdh and gyrB. For detection of pks islands, we performed PCR for the clbB and clbN genes as colibactin system markers. Phylogenetic group B2 was the most common, accounting for 54.1% (N=79) of the isolates, followed by group D with 29.5% (N=43), group A with 11.6% (N=17), and group B1 with 4.8%. Of the group B2 isolates, 40.5% were ST131 strains and 32.9% carried pks islands. Only three ST131 isolates in group B2 carried the clbB and clbN genes, while the other 23 ST131 isolates did not. The pks gene might not be associated with ST131 strains.

Notifiable diseases under Philippine integrated disease surveillance and response (PIDSR) among patients seen at the Eastern Visayas Regional Medical Center (EVRMC) before and after super typhoon Yolanda

@#<p style="text-align: justify;"><strong>INTRODUCTION:</strong> Typhoon Haiyan, or Typhoon "Yolanda" in the Philippines, caused catastrophic damage last November 8, 2013 in the islands of Leyte. As of April 17, 201, NDRRMC confirmed 6,300 fatalities across the country and around 5,877 were from Eastern Visayas. The actual death toll remained unclear although it is being claimed to be about 10,000 in Tacloban City alone.</p><p style="text-align: justify;"><strong>OBJECTIVE:</strong> This study aimed to determine the transmission of notifiable diseases under PIDSR as to increase in morbidity, deaths and case fatality rates among patients consulted and/or admitted at EVRMC before and after ST Yolanda.</p><p style="text-align: justify;"><strong>MATERIALS AND METHODS:</strong> This is a descriptive study which included all patients who sought consultation and/or admission in EVRMC with clinical diagnosis of any notifiable disease under the PIDSR reference list.</p><p style="text-align: justify;"><strong>RESULTS:</strong> A cumulative total of 8,299 patients with notifiable diseases sought and/or admission between November 2012 - October 2013 and November 2013 - October 2014. Of which, 3,873 or 46.67% were cases before Super Typhoon Yolanda while 4,426 or 53.33% were cases a year after. Patients below 14 years old were mostly affected after the disaster. There were few patients, 70 years old and above who sought consultation and/or admission. As to occurrence between sexes, there were more females affected than males after the disaster which comprised of 51.4% of the total. As to geographic distribution, there were more cases coming from the 1st district of Leyte including Tacloban City comprising 61.58% compared to its occurrence prior to the disaster.  As to the number of cases under Category I, an increased cases of measles from 2 cases to 356 or an increase of 99.44% after the disaster. Notifiable diseases under Category II comprised 91.53% of the total post disaster with an increase of 12.5% from the total cases the previous year. Acute watery diarrhea had the highest number of patients affected then, was followed by Dengue fever,  27.43% and Acute bloody diarrhea, 2.35%. Chikungunya increased from 10 cases the previous year to 33. As to deaths, there was no increase under Category I but, under Category II, an increase of 26.1% after the typhoon was observed. Among these, were Acute watery diarrhea, Dengue fever, Influenza like illness and Measles after disaster.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> During calamities, everything is affected, from infrastructure, agriculture and most of all the people. Transmission of different infectious diseases occur because of displacement of the population, lack of safe water supply and sanitation facilities and, lack of available health care services.</p>

Contributions to the bryological knowledge of ASPA 125, Fildes Peninsula, King George Island

BACKGROUND: With 29 Km2, the Fildes Peninsula is the largest ice free area in King George Island and probably in Antarctica. The region is house of six permanent bases including the only airport in the South Shetlands, which led to impacts on its original landscape and vegetation. In recognition for the need to protect natural values, an Antarctic Specially Protected Area (ASPA 125) was established in the region. Focused mostly on protecting the fossils, the ASPA also plays a role in protecting the vegetation but so far, the management plan for the area does not contain a list of moss species present there. RESULTS: We provided an updated study and checklist of mosses present in ASPA 125. A key to species identification and photographs of main morphological features are also available in this paper. Also, six new occurrences are reported for Fildes Peninsula. CONCLUSION: Considering the scarce knowledge about specific local floras in Antarctica associated with highly impacted area, of which only a fraction is protected, it is suggested the necessity to invest in detailed sampling studies, as well as in a better understanding of the local floras interactions in Antarctica.
