Embriogénesis, desarrollo larval y sobrevivencia post-asentamiento del coral Orbicella annularis (Scleractinia: Merulinidae)

Introducción: Las poblaciones del coral Orbicella annularis han mostrado bajo reclutamiento en el Caribe. Uno de los cuellos de botella demográficos es la alta mortalidad en las primeras etapas de desarrollo. El conocimiento detallado del ciclo y las tasas de supervivencia de estas fases nos permitirá ayudar en la recuperación de la población y la restauración de los arrecifes. Objetivo: Describir la embriogénesis y estadios larvarios obtenidos por fertilización asistida y medir las tasas de asentamiento y supervivencia de las larvas en sustratos artificiales, antes de ser trasplantadas al arrecife. Métodos: Seis días después de la luna llena de septiembre de 2021, se recolectaron bolsas de gametos de ocho colonias de O. annularis en el Parque Nacional Natural Los Corales del Rosario y San Bernardo, Colombia, y se llevaron al laboratorio. Se realizó fecundación cruzada, se siguió el desarrollo embrionario y larvario hasta el asentamiento larval y se registró supervivencia hasta el día 41. Las larvas se mantuvieron en tres tanques con agua de mar filtrada con 126 sustratos marcados, previamente acondicionados con algas coralináceas costrosas. Luego, los sustratos se trasplantaron al arrecife. Resultados: El inicio del desarrollo embrionario ocurrió 1.11 hAF (horas después de la fertilización), cuando las células mostraron signos de la primera división, y duró hasta 104.59 hAF cuando comenzaron a metamorfosearse. El asentamiento de larvas se observó al sexto día AF. Veintiún días después de la fecundación se encontraron zooxantelas. La supervivencia de las larvas después del asentamiento fue de 27.5 %. Conclusión: En este primer esfuerzo de propagación sexual utilizando O. annularis en Colombia, 1.4 % de larvas competentes completaron todo el proceso de desarrollo. Aunque la tasa de supervivencia fue baja, estos resultados se suman a los esfuerzos de restauración de corales en el Caribe en los que se ayuda a las especies a aumentar la supervivencia de los corales en sus primeras etapas de desarrollo.

Introduction: Populations of the coral Orbicella annularis have shown low recruitment in the Caribbean. One of the demographic bottlenecks is the high mortality in the early stages of development. Detailed knowledge of the cycle and survival rates of these phases will allow us to assist in population recovery and reef restoration. Objective: To describe the embryogenesis and larval stages obtained by assisted fertilization and measure the settlement and survival rates of larvae on artificial substrates, before being outplanted to the reef. Methods: Six days after the full moon in September 2021, gamete bundles were collected from eight O. annularis colonies in Los Corales del Rosario and San Bernardo National Natural Park, Colombia and brought to the laboratory. Cross fertilization was carried out and embryonic and larval development were followed until larval settlement and survival was recorded until day 41. The larvae were kept in three tanks with filtered sea water with 126 tagged substrates, previously conditioned with crustose coralline algae. The substrates were then outplanted to the reef. Results: The onset of embryonic development occurred 1.11 hAF (hours after fertilization), when cells showed signs of the first cleavage, and lasted until 104.59 hAF when they began to metamorphose. Larvae settlement was observed on the sixth day AF. Twenty-one days after fertilization, zooxanthellae were found. Post-settlement larval survival was 27.5 %. Conclusions: In this first sexual propagation effort using O. annularis in Colombia, 1.4 % of competent larvae completed the entire development process. Although low survival rate, these results add to coral restoration efforts in the Caribbean in which species are assisted to increase the survival of corals in their early stages of development.

Recruitment of crustose coralline algae on tiles material for monitoring coral larvae settlement's consolidators at Nature Reserve Pulau Sempu, East Java, Indonesia / Recrutamento de algas coralinas crustosas em azulejos para monitorar consolidadores de assentamentos de larvas de coral na Reserva Natural Pulau Sempu, Java Oriental, Indonésia

Crustose coralline algae (Corallinophycideae) are red algae that produced calcium carbonate and are well recognized as foundation species in the epipelagic zone of the marine ecosystem. These algae induced settlement juvenile of coral by released chemical cues from bacterial communities on the surface of their colonies. Their extracellular calcium carbonate also can stabilize reef structure that influencing many invertebrate attaches and growth in the seabed. Crustose coralline algae (CCA) have obtained attention because of their distribution and health compromise to increasing seawater temperature, ocean acidification, and pollutant. As a cryptic species in the ecosystem, the presence of CCA recruit sometimes doesn’t have attention, especially on their capability to occupy the empty space. This study aimed to document coverage and number of CCA recruit in two different recruitment tile’s material. The highest CCA percentage of the cover was showed inside surface than others surface in all stations. Light intensity and low sedimentation were suggested as a key factor of success of high coverage. Overall, station higher CCA recruits have shown from Tiga Warna. Low sedimentation and protection from aerial exposure became the main reason for it. No significant difference number of CCA recruits between marble and sandstone in this study. Successful CCA recruitment in this study can give a wide picture that natural recruitment of coral and other reef biodiversity in Southern Malang might be will succeed because of the abundance of coralline algae that support their life history stage.

As algas coralinas crustosas (Corallinophycideae) são algas vermelhas que produzem carbonato de cálcio e são bem reconhecidas como espécies de base na zona epipelágica do ecossistema marinho. Essas algas induziram o assentamento juvenil de coral por meio de estímulos químicos liberados por comunidades bacterianas na superfície de suas colônias. Seu carbonato de cálcio extracelular também pode estabilizar a estrutura do recife que influencia muitos invertebrados anexados e crescimento no fundo do mar. As algas coralinas crustosas (CCA) têm obtido atenção devido à sua distribuição e comprometimento da saúde com o aumento da temperatura da água do mar, acidificação dos oceanos e poluentes. Como uma espécie enigmática no ecossistema, a presença de recrutamento CCA às vezes não recebe atenção, especialmente em sua capacidade de ocupar o espaço vazio. Este estudo teve como objetivo documentar a cobertura e o número de recrutamento de CCA em dois materiais de recrutamento diferentes. A maior porcentagem de CCA da cobertura foi mostrada na superfície interna do que nas outras superfícies em todas as estações. A intensidade da luz e a baixa sedimentação foram sugeridas como um fator-chave para o sucesso da alta cobertura. De modo geral, recrutas de CCA mais graduados mostraram-se em Tiga Warna. A baixa sedimentação e a proteção contra a exposição aérea se tornaram a principal razão para isso. Não houve diferença significativa no número de recrutas CCA entre mármore e arenito neste estudo. O recrutamento bem-sucedido de CCA neste estudo pode dar uma imagem ampla de que o recrutamento natural de corais e outros recifes da biodiversidade no sul de Malang será bem-sucedido por causa da abundância de algas coralinas que sustentam seu estágio de história de vida.

Internal ultrastructure of the planktonic larva of the coral Porites panamensis (Anthozoa: Scleractinia) / Ultraestructura interna de la larva planctónica del coral Porites panamensis (Anthozoa: Scleractinia)

Abstract Introduction: The scleractinian coral life cycle includes planktonic larvae that settle on the benthos, allowing the primary polyp to clone and build a sexually reproducing adult colony. The larval physiology and ecology of Eastern Tropical Pacific scleractinians needs the exploration of basic aspects such as the internal morphology of planulae. Objective: To describe histological and cytological characteristics of Porites panamensis larvae. Methods: During August-July 2019, at Islas Marias Biosphere Reserve, Central Mexican Pacific, we made 14 collections of coral larvae and identified the species with cytochrome oxidase subunit 1 gene. We used a scanning electron microscope and other techniques. Results: The ectoderm was composed by heterogeneous, mono-ciliated, columnar epithelial cells. Nematocysts were clustered at the oral pole of the ectoderm, and cells were evident in the aboral pole of the ectoderm gland. The endoderm had secretory cells, lipids and symbionts. Conclusions: The abundance of secretory cells and nematocysts in the aboral pole suggests their importance in substrate exploration and larval settlement. Our results support previous descriptions of larval ultrastructure in other coral species.

Resumen Introducción: El ciclo de vida del coral escleractinio incluye larvas planctónicas que se asientan en el bentos, lo que permite que el pólipo primario se clone y construya una colonia de adultos con reproducción sexual. La fisiología y ecología larvaria de los escleractinios del Pacífico Tropical Oriental necesita la exploración de aspectos básicos como la morfología interna de las plánulas. Objetivo: Describir las características histológicas y citológicas de las larvas de Porites panamensis. Métodos: Durante agosto-julio 2019, en la Reserva de la Biosfera Islas Marías, Pacífico Central Mexicano, realizamos 14 recolectas de larvas de coral e identificamos las especies con el gen citocromo oxidasa subunidad 1. Utilizamos un microscopio electrónico de barrido y otras técnicas. Resultados: El ectodermo está compuesto por células epiteliales columnares heterogéneas, monociliadas. Los nematocistos se agrupan en el polo oral del ectodermo, mientras que en el polo aboral son visibles células glandulares. El endodermo presentó células secretoras, lípidos y simbiontes. Conclusiones: La abundancia de células secretoras y nematocistos en el polo aboral sugiere su importancia en la exploración del sustrato y asentamiento larvario. Nuestros resultados respaldan las descripciones previas de la ultraestructura de las larvas en otras especies de coral.

Condiciones socioambientales y prevalencia de enfermedades de la piel en un asentamiento urbano precario de Asunción (Paraguay) / Socio-Environmental Conditions and Prevalence of Skin Diseases in a Precarious Urban Settlement in Asunción (Paraguay) / Condições socioambientais e prevalência de dermatoses em um assentamento urbano precário em Assunção (Paraguai)

Introducción: se buscó analizar la prevalencia de enfermedades dermatológicas de la población de un asentamiento urbano precario próximo al vertedero municipal de Asunción (Paraguay), atendiendo a la exposición de las condiciones socioambientales. Materiales y métodos: estudio descriptivo y transversal con una muestra no probabilística intencional que incluyó a 77 personas de entre 5 meses y 76 años. Resultados: en el momento del examen físico, el 96.2 % de las personas presentó, al menos, una lesión cutánea, y el 79.2 %, una o más enfermedades infecciosas de piel; sin embargo, el 77.9 % no había recu-rrido a consulta médica. Las más sobresalientes fueron las micosis (35.1 %), las bacterianas (35.1 %) y las ectoparasitosis (27.3 %). Se identificó que la prevalencia de enfermedades bacterianas de piel apunta a una posible mayor exposición a condiciones adversas como: un clima subtropical de altas temperaturas y húmedo, una alta relación de convivientes en el hogar por dormitorio, problemas de provisión de agua y suelos de arena en los hogares, así como un sistema de evacuación de excretas deficiente, la presencia de animales con escasa vigilancia sanitaria, la proximidad a arroyos y cauces al aire libre depositarios de materia cloacal y el impacto recurrente de raudales los días de intensa lluvia. Conclusión: los resul-tados sugieren que la alta prevalencia de enfermedades cutáneas infecciosas podría relacionarse con una mayor exposición a condiciones socioambientales locales adversas, que son factores relevantes por tener en cuenta para mejorar la atención a la salud de las enfermedades dermatológicas de la población urbana que habita en un asentamiento urbano precario

Introduction: This study analyzes the prevalence of dermatological diseases in the population of a precarious urban settlement near the municipal landfill of Asunción (Paraguay), in relation to expo-sure to socio-environmental conditions. Materials and methods: descriptive, cross-sectional study with a non-probabilistic purposive sample that included 77 people aged between 5 months and 76 years. Results: at the time of physical examination, 96.2% of the people presented at least one skin lesion and 79.2% one or more infectious skin diseases, but 77.9% had not consulted a doctor. The most prominent were mycoses (35.1%), bacterial (35.1%) and ectoparasitoses (27.3%). It was identified that the preva-lence of bacterial skin diseases points to possible increased exposure to adverse conditions such as: a subtropical climate with high temperatures and humidity, a high ratio of people living in the household per bedroom, water supply problems and sandy soils in homes, as well as a deficient excreta disposal system, the presence of animals with poor sanitary surveillance, proximity to streams and open-air waterways that deposit sewage and the recurrent impact of floods on days of heavy rainfall. Conclusion:the results suggest that the high prevalence of infectious skin diseases could be related to increased exposure to adverse local socio-environmental conditions, which are relevant factors to be taken into to improve the health care of skin diseases in the urban population living in a slum settlement

Introdução: este estudo analisa a prevalência de doenças dermatológicas na população de um assen-tamento urbano precário próximo ao aterro sanitário municipal de Asunción (Paraguai) em relação à exposição às condições socioambientais. Materiais e métodos: estudo descritivo, transversal, com uma amostra não-probabilística de propósito que incluiu 77 pessoas com idade entre 5 meses e 76 anos. Resultados: no momento do exame físico, 96,2% das pessoas tinham pelo menos uma lesão de pele e 79,2% tinham uma ou mais doenças infecciosas de pele, mas 77,9% não tinham consultado um médico. As mais importantes foram micoses (35,1%), bacterianas (35,1%) e ectoparasitoses (27,3%). A preva-lência de doenças bacterianas da pele foi identificada como apontando para um possível aumento da exposição a condições adversas tais como: um clima subtropical com altas temperaturas e umidade, uma alta proporção de pessoas vivendo na casa por quarto, problemas de abastecimento de água e solos arenosos nas habitações, bem como um sistema de eliminação de excrementos deficiente, a presença de animais com vigilância sanitária deficiente, proximidade a riachos e cursos de água abertos que depositam águas residuais, e o impacto recorrente de enchentes em dias de chuvas fortes. Conclusão:Os resultados sugerem que a alta prevalência de doenças infecciosas de pele pode estar relacionada ao aumento da exposição a condições sócio-ambientais locais adversas, que são fatores relevantes a serem considerados para melhorar os cuidados com doenças de pele na população urbana que vive em uma favela

Acesso à água e esgotos em ocupação urbana na Região Metropolitana de Belo Horizonte: efeitos na saúde, qualidade de vida e relações de gênero / Access to water and sanitation in urban occupation in the Metropolitan Region of Belo Horizonte: effects on health, quality of life and gender relations

Resumo O artigo visa compreender como ocorre o acesso à água e ao esgotamento sanitário na Ocupação Vitória e a percepção dos moradores acerca da associação entre esse acesso e as condições de saúde: aparecimento de doenças, qualidade de vida e as relações de gênero na comunidade. Trata-se de estudo qualitativo, fundamentado na imersão no trabalho de campo, empregando observação participante na Ocupação e em entrevistas com seus moradores. Observou-se a precariedade do acesso à água pela população, que ocorre por meio de ligações irregulares às redes formais, e a predominância de fossas rudimentares. A população relaciona a falta de saneamento com o surgimento de doenças infecciosas e parasitárias e impactos sobre a desigualdade de gênero. O acesso inadequado à água e esgoto impacta a qualidade de vida da comunidade ao comprometer a produção de alimentos agroecológicos e as práticas culturais e identitárias. A informalidade do assentamento se traduz em maior vulnerabilidade social e maior exposição da população a efeitos sobre sua saúde, principalmente de mulheres e crianças.

Abstract The article aims to understand how access to water and sanitation occurs in the Vitória Occupation and the residents' perception of the association between this access and health conditions: the emergence of diseases, quality of life and gender relations in the community. This is a qualitative study, based on immersion in fieldwork, employing participant observation in the Occupation and in interviews with residents of the Occupation. It was observed the precariousness of access to water by the population, which occurs through irregular connections to formal networks, and the predominance of rudimentary septic tanks. The population relates the lack of sanitation with the emergence of infectious and parasitic diseases and impacts on gender inequality. Inadequate access to water and sewage impacts the community's quality of life by compromising the production of agroecological food and cultural and identity practices. The informality of the settlement translates into greater social vulnerability and greater exposure of the population to effects on their health, especially on women and children.

Design and application of intelligent bedside mobile payment from the perspective of industry and finance integration / 中华医院管理杂志

Based on the ideas of management systemization, system standardization, process specialisation, post accountability, duty formalization, form informatization, information digitization and digital intelligence, the smart, mobile and paperless bedside billing service was developed which incorporated both functional and financial prospects. The innovation was realized by Internet+ bedside billing and an integrated information platform, so that the inter-hospital billing system could be connected to the medical insurance system, electrical receive system and commercial insurance system. This saved manpower and equipment deployment, and improved service quality. The bedside intelligent mobile billing system of a hospital was launched in January 2021, and the average discharge billing time of inpatients in 2020 and 2021 was 44.36 min and 30.59 min, respectively, and the online billing fee time was significantly shorter than offline billing in 2021, and the differences were all significant( P<0.01).

Respondents that seek health/treatment in hospitals (50.9) differ insignificantly from those that seek health through traditional remedies (49.1). Cost of treatment was reported to be high and moderate by 31.9% and 65.5% respondents respectively. Poor healthcare delivery was implicated as major dissatisfaction with treatment by 76.4% of respondents.Conclusion:Malaria is a major health problem encountered by pregnant women in agrarian locales. Hence, girls should be exposed to malaria awareness programs an earlier stage of life

Ciudad y bienestar: la tensión entre la urbanización y el habitar / City and Welfare: The Tension Between Urbanization & Settlement

Resumen Este texto reflexiona sobre cómo la tensión entre la urbanización y el habitar expone a sus habitantes a un constante estado de estrés y depresión. Los conduce a hábitos nocivos, que derivan en enfermedades crónicas degenerativas. Por lo tanto, la ciudad no es un espacio para el bienestar de los sujetos, porque, los factores que permiten alcanzar el bienestar, que son los lugares, los objetos, los bienes y salud, no son tomados en cuenta. De ahí que el bienestar tiene un fuerte vínculo con el espacio, el tiempo y la sociedad. Así, la urbanización podría producir espacios armónicos, que permitan un desarrollo, físico, mental y económico.

Abstract: This text refl ects on how the tension between urbanization and settlement exposes inhabitants to a constant state of stress and depression. Which points them towards harmful habits, leading to chronic degenerative diseases. Therefore, the city is not a space oriented to the welfare of the subjects. Because, the factors that allow achieving well-being, which are places, objects, goods and health, are not taken into account. Hence, well-being, has a strong link with space, time and society. Where urbanization, would have to produce those harmonic spaces, which allow development, both physical and mental as well as economic.

Caracterização de Escherichia coli diarreiogênica isolada de água subterrânea para consumo humano em um assentamento rural / Characterization of diarrheagenic Escherichia coli isolated from underground water for human consumption in a rural settlement

Escherichia coli diarreiogênica (DEC) é um importante agente de infecções gastrointestinais transmitidas pela água. O trabalho teve como objetivo avaliar a qualidade microbiológica e físicoquímica de 58 amostras de água subterrânea in natura para consumo de um assentamento rural e caracterizar os isolados de E. coli, genotipicamente dentro dos patotipos de DEC, pela técnica da PCR, e fenotipicamente. Todas as amostras apresentaram contaminação por coliformes totais e 36 (62,1%) por E. coli. Em células HEp-2, dos 170 isolados de E. coli, 106 (62,36%) apresentaram AA, 15 (8,82%) AD, 17 (10%) adesão não caracterizado e 32 (18,82%) foram não aderentes. Quanto à formação de biofilme, 126 (74,12%) cepas são formadoras, e 44 (25,88%) não formaram biofilme. Foram identificadas DEC em 6,89% das amostras de água: três (5,17%) ETEC e uma (1,72%) EAEC. EAEC apresentou AA e as três cepas de ETEC apresentaram AD, AA e não definida. Todas as DEC foram formadoras de biofilme. Dois isolados de ETEC apresentaram resistência à ampicilina e tetraciclina, uma ETEC à aminoglicosídeos, e EAEC foi sensível a todos os antibióticos testados. As ETEC foram classificadas no filogrupo B1 e a EAEC no E. Os sorotipos encontrados foram: O24:H21, OR:H21, O17:H46 e O6:H12. Todas as amostras estavam dentro dos parâmetros normais de flúor e 13 (22,4%) apresentaram resultados acima do padrão permitido de turbidez. A presença de E. coli e DEC nas amostras de água indica a necessidade de adoção de medidas que evitem a contaminação da água fornecida à população, evitando, assim, a transmissão de doenças.(AU)

Diarrheogenic Escherichia coli (DEC) is an important agent of waterborne gastrointestinal infections. The objective of this work was to evaluate the microbiological and physico-chemical quality of 58 freshwater groundwater samples for the consumption of a rural settlement and to characterize the E. coli isolates, genotyped within the DEC pathophyses, by the PCR technique, and phenotypically. All water samples presented contamination with total coliforms, and 36 (62.1%) with E. coli. In HEp-2 cells, of 170 E. coli isolates, 106 (62.36%) showed AA, 15 (8.82%) AD, 17 (10%) noncharacterized adhesion and 32 (18.82%) were non-adherent. As for biofilm formation, 126 (74.12%) strains are forming, and 44 (25.88%) did not form biofilm. DEC was identified in 6.89% of the water samples with E. coli: three (5.17%) with enterotoxigenic E. coli (ETEC), and one (1.72%) with enteroaggregative E. coli (EAEC). EAEC showed aggregative adherence, whereas various ETEC strains presented diffuse, aggregative, and non-defined adherence. All DEC strains were biofilm forming. Two isolates of ETEC showed resistance to ampicillin and tetracycline, and one isolate showed resistance to aminoglycosides. The EAEC isolate was sensitive to all antibiotics tested. All ETECs were classified into phylogenetic B1 and EAEC in E. The serotypes identified in our study were: O24:H21, ONT:H21, O17:H46, and O6:H12. All water samples were within normal fluorine parameters; however, measured turbidity was above the permitted standard in 13 (22.4%) samples. The presence of E. coli and DEC in water samples indicates the need to take action to prevent contamination of water resources accessed by people to prevent the transmission of diseases.(AU)

Early life history of the Caribbean coral Orbicella faveolata (Scleractinia: Merulinidae)

Introduction: Rehabilitation of hermatypic coral species that have declined in the Caribbean in recent decades is a priority. Production of sexual recruits is considered the best restoration method to aid affected populations. Objective: To gain knowledge of early life stages of Orbicella faveolata and to enhance production of new sexual recruits. Methods: Gamete bundles from the coral species O. faveolata were collected over two years (2018 and 2019) from Los Corales del Rosario y de San Bernardo Natural National Park, Cartagena, Colombia. Assisted fertilization, larval rearing, settlement (onto crustose coralline algae, CCA) and post settlement survival in laboratory conditions were monitored. Results: Embryonic and larval development were documented over 55 hours after the first cleavage, when larvae were fully developed and started pre-settlement behavior. Settlement began 7 days after first cleavage and after 37 days polyps had acquired zooxanthellae. Larval settlement was higher on Lythophyllum congestum and Titanoderma prototypum than in response to Porolithon pachydermum, Neogoniolithon sp., Hydrolithon sp., and Lythophyllum sp. Larvae did not settle on dead coral or on the negative control (sterilized seawater). After the first week post settlement survival was 59 % amongst O. faveolata recruits. During the second week, survival dropped to 42 %, and was further reduced to 0 % at the end of the third week. Conclusions: O. faveolata larvae require cues from certain CCA species to settle, they do not settle in absence of CCA. Increased larvae availability is possible through assisted fertilization in the laboratory, however, due to the high mortality in early post-settlement phases, additional research needs to be conducted in order to scale up larvae production and improve understanding of the cues that enhance settlement and the factors which cause post-settlement mortality.

Introducción: La rehabilitación de las especies de corales hermatípicos del Caribe que han disminuido en las últimas décadas es una prioridad. La producción de reclutas sexuales se considera el mejor método de restauración para ayudar a las poblaciones afectadas. Objetivo: Obtener conocimiento de las primeras etapas de la vida de O. faveolata y mejorar la producción de nuevos reclutas sexuales. Métodos: Por dos años (2018 y 2019), seis días después de luna llena en septiembre, se recolectaron paquetes gaméticos en arrecifes del Parque Nacional Natural Los Corales del Rosario y de San Bernardo, Cartagena, Colombia. Se siguió la fertilización asistida, la cría de larvas, el asentamiento y la supervivencia posterior al asentamiento en algas coralinas costrosas (ACC) en condiciones de laboratorio. Resultados: El desarrollo de embriones y larvas se documenta a lo largo de 55 h después del primer clivaje, cuando la larva está desarrollada completamente y comenzó el comportamiento previo al asentamiento. El asentamiento comienza 7 días después del primer clivaje y 37 días después, la mayoría de los pólipos presentan zooxantelas. El asentamiento larval fue más alto en Lythophyllum congestum y Titanoderma prototypum que en respuesta a Porolithon pachydermum, Neogoniolithon sp., Hydrolithon sp., y Lythophyllum sp. No hubo asentamiento sobre coral muerto ni en el control negativo (agua de mar esterilizada). La supervivencia bajó de un 59 % en la primera semana después del asentamiento, a 42 % durante la segunda semana y 0 % para el final de la tercera semana. Conclusiones: Las larvas de O. faveolata requieren señales de ciertas especies de ACC para asentarse, ellas no se asientan en ausencia de ACC. La disponibilidad de larvas es posible mediante la fertilización asistida en laboratorio. Sin embargo, debido a la alta mortalidad en las primeras fases posteriores al asentamiento, queda mucho por hacer para aumentar la producción de larvas y mejorar nuestro conocimiento y comprensión de las señales que mejoran el asentamiento y las que previenen o inhiben la supervivencia del recluta.

Study on oral smokeless tobacco use among migrant labourers and their attitude towards tobacco cessation in an urban settlement in Ernakulam district of Kerala

Background: Interstate migrant workers in the state of Kerala are increasing day by day. Tobacco usage is quite common among them; however, there are only few studies about oral smokeless tobacco consumption among them. The objectives of the study were to study the prevalence of oral smokeless tobacco use among migrant labourers in an urban settlement in Ernakulam district of Kerala and to assess the knowledge and attitude of users towards cessation. Methods: A cross sectional study was conducted among 140 migrant workers residing in an urban settlement in Kochi. Data regarding their socio demographic characteristics, knowledge, attitude and practices of smokeless tobacco consumption was collected using a questionnaire adapted from the global adult tobacco survey questionnaire (GATS). Data was entered into excel sheet and was analyzed using Epi Info. Results: The prevalence of oral smokeless tobacco was found to be 32.85%. Of which, majority of them used a tobacco-lime mixture called Khani (50%) and used tobacco on a daily basis (65.2%). It was observed that 71.74% of the users were unaware of the ill effects of the use of smokeless tobacco and 69.57% of them were not interested in quitting this habit. Among those who had quit, majority of them had done it on their will power alone. Conclusions: The use of smokeless tobacco is quite prevalent among the migrant population. Effective behavioural change communication activities need to be directed towards them.

BIOFILMS AND EXTRACTS FROM BACTERIA PRODUCING "QUORUM SENSING' SIGNALING MOLECULES PROMOTE CHEMOTAXIS AND SETTLEMENT BEHAVIORS IN Hydractinia Symbiolongicarpus (Cnidaria: Hydrozoa) LARVAE / Biopelículas y extractos de bacterias que producen moléculas de señalización de "Quorum Sensing' promueven comportamientos de quimiotaxis y asentamiento en larvas de Hydractinia symbiolongicarpus (Cnidaria: Hydrozoa)

ABSTRACT Many sessile marine invertebrates have life cycles involving the development of larvae that settle on specific substrates to initiate metamorphosis to juvenile forms. Although is recognized that bacterial biofilms play a role in this process, the responsible chemical cues are beginning to be investigated. Here, we tested the role of substrate-specific bacteria biofilms and their Quorum Sensing Signaling Molecule (QSSM) extracts on chemotaxis and settlement of larvae from Hydractinia symbiolongicarpus, a hydroid that grows on gastropod shells occupied by hermit crabs. We isolated and taxonomically identified by 16S rDNA sequencing, 14 bacterial strains from shells having H. symbiolongicarpus. Three isolates, Shigella flexneri, Microbacterium liquefaciens, and Kocuria erythromyxa, were identified to produce QSSMs using biosensors detecting N-acyl-L-homoserine lactones. Multispecies biofilms and QSSM extracts from these bacteria showed a positive chemotactic effect on H. symbiolongicarpus larvae, a phenomenon not observed with mutant strains of E. coli and Chromobacterium violaceum that are unable to produce QSSMs. These biofilms and QSSMs extracts induced high rates of larval attachment, although only 1 % of the attached larvae metamorphosed to primary polyps, in contrast to 99 % of larvae incubated with CsCl, an artificial inductor of attachment and metamorphosis. These observations suggest that bacterial QSSMs participate in H. symbiolongicarpus substrate selection by inducing larval chemotaxis and attachment. Furthermore, they support the notion that settlement in cnidarians is decoupled into two processes, attachment to the substrate and metamorphosis to a primary polyp, where QSSMs likely participate in the former but not in the latter.

RESUMEN Muchos invertebrados marinos sésiles tienen ciclos de vida que involucran el desarrollo de larvas que se asientan en sustratos específicos iniciando su metamorfosis a formas juveniles. Aunque es conocido que biopelículas bacterianas participan en este proceso, las señales químicas responsables hasta ahora se empiezan a investigar. Aquí evaluamos el papel de biofilms bacterianos y sus extractos de moléculas de señalización de "Quorum Sensing' (QSSM) sobre la quimiotaxis y el asentamiento larvario en Hydractinia symbiolongicarpus, un hidrozoario que crece sobre conchas de gastrópodos ocupadas por cangrejos ermitaños. Nosotros aislamos e identificamos taxonómicamente por secuenciación de rDNA 16S 14 cepas bacterianas de conchas con H. symbiolongicarpus. Tres de ellas, Shigella flexneri, Microbacterium liquefaciens, and Kocuria erythromyxa, mostraron producción de QSSMs usando biosensores que detectan N-acil-L-homoserin lactonas. Biopelículas y extractos de QSSMs de estas bacterias mostraron efectos quimiotácticos sobre larvas de H. symbiolongicarpus, efecto no observado en ensayos con cepas mutantes de E. coli y Chromobacterium violaceum que son incapaces de producir QSSMs. Las biopelículas y sus extractos indujeron adhesión larvaria sobre superficies, aunque solamente el 1 % de las larvas asentadas hicieron metamorfosis hacia pólipo primario, en contraste con 99 % de larvas incubadas con CsCl, un inductor artificial de asentamiento y metamorfosis. Estas observaciones sugieren que QSSMs de biopelículas bacterianas participan en la selección de sustrato de H. symbiolongicarpus, induciendo quimiotaxis y asentamiento de sus larvas. También sugieren que el asentamiento en cnidarios tiene dos procesos, adhesión y metamorfosis, donde las QSSMs participarían en el primero, pero no en el segundo.

Exploring the innovative " post-payment" for medical service in Hangzhou / 中华医院管理杂志

Post-payment for patients can minimize their errands and improve their medical experience. Since February 2019, Hangzhou Municipal Health Commission began to try the " post-payment" service. This mode is integrated into the municipal credit system, and the patients can obtain the corresponding credit line according to their credit rating. Within such line, the patient can pay only once for all their medical services received per visit. The mode covers all Hangzhou residents with credit rating and has served nearly 20 million outpatient and emergency patients with expedient services. Thanks to the reform, the number of payment for patients to see a doctor reduced from an average of 2 to 3 times to only 1 time. It is proved that the credit system can realize payment after medical service and it is controllable.

Analysis of direct settlement of non-local patients′medical insurance at a tertiary hospital in Tianjin / 中华医院管理杂志

Objective To analyze the patient information and hospitalization of non-local patients whose medical expenses will be directly settled with their local medical insurance network by a tertiary hospital in Tianjin, and to suggest on further development of direct settlement of medical insurance networking for non-local patients in Tianjin. Methods A retrospective analysis was made on the data of 1 068 non-local patients whose medical expenses were directly settled via medical insurance network from September 2017 to September 2018. Results The majority of non-local patients came from Hebei province, mostly over 51 years old; these inpatient focus on the renown key disciplines such as urology and cardiology;about a half of them were surgical patients; the proportion of patients with chronic diseases was high. These non-local patients in Tianjin feature higher age, more hospitalizations, lower self-paid expenses and lower overall hospitalization costs. Conclusions We should strictly control the referral system of non-local patients, strengthen medical support to areas of poor medical conditions, strengthen the hierarchical medical system; enhance the publicity of non-local patient online settlement and policy awareness, and simplify the filing process. It is also important to enhance network construction and data stability.

Diseases distribution and data analysis of children patients with allopatry direct settlement of medical insurance / 中华医院管理杂志

Objective To research the performance of direct settlement for allopatry medical insurance at a tertiary specialized children′s hospital in Beijing, and to analyze the basics of these inpatients and the structural characteristics of their diseases, for basis and suggestions for improving the policy of direct settlement of allopatry medical insurance. Methods A statistical description of direct settlement data was made for allopatry medical insurance at this hospital from August 2017 to July 2018, to study the age, hometown, attribute, distribution of inpatient departments and disease distribution of these children. Results The patients mainly came upon referrals, preschool children in most cases. The average daily hospitalization cost of the disease was high relatively, and the number of hospitalizations was high as well. Compared with children inpatients in Beijing, these patients tend to come for surgical treatment for malignant tumors and congenital diseases.Conclusions The allopatry direct settlement of children′s medical insurance settlement is found mostly with diseases those are complicated and severe. The management of such settlement can be improved by cooperating with their local institutions in advance, data checking in the course, simplifying the formalities for special diseases, and the differential reimbursement ratio for these patients.

Information analysis of patients with allopatry direct settlement of medical insurance at an oncology hospital / 中华医院管理杂志

Objective To propose on and improve direct settlements by medical insurance offices and hospital systems in their processing of medical treatment in allopatry (MTA), by analyzing such data as the homepages of medical records of such inpatients at a tertiary cancer hospital with their medical expenses settled directly. Methods Data of 6 379 MTA inpatients with direct settlements of in-hospital fees from April 2017 to March 2018 were included in this study. Such data were used to identify the change trend of their case counts and their regional distribution, and analyzed with hierarchical clustering to calculate the settlement counts of various provinces. Results Analyses found that the total cases of such patients remained stable at the hospital, yet the cases of direct settlement rose from five to 1 263, and the proportion of direct settlement among all MTA inpatients rose month by month from 0.14% to 29.26%. Most of MTA inpatients come from Hebei, Shandong, Inner Mongolia and Shanxi provinces in turn, yet the direct settlement counts and hospitalization case trends appear different. Clustering results indicate Hebei as the type-1 province with the highest proportion of direct settlement inpatients, accounting for 30. 41% ;Shandong, Inner Mongolia and Shanxi as the type-2 provinces, accounting for 15. 05% , 13. 45% and 11.00% respectively; Liaoning, Henan and Heilongjiang as the type-3 provinces, accounting for 6.79% , 4.81% and 4.42% respectively; while the rest provinces as the type-4, accounting for less than 3%. Conclusions Regional distribution varies distinctively among such inpatients, and the number of these inpatients keeps rising stably. In such circumstances, hospitals are recommended to enhance their management in strengthening medical insurance audit systems, speeding up settlement, and building regional medical alliances.

Sense of belonging and social identity on the settlement intentions of rural-urban migrants: evidence from China / O efeito do senso e identidade social nas intenções de assentamento de migrantes rurais-urbanos: evidências da China

ABSTRACT: Drawing upon data from the China Labor-force Dynamics Survey (CLDS) of 2012 and 2014, this paper uses the panel binary choice model to examine the determinants of the settlement intentions of rural-urban migrants. Results showed that both a sense of belonging and social identity play important roles in determining rural-urban migrants' settlement decisions. Besides these, wage, education, and health also affect the willingness of migrant workers to settle in a given area. Therefore, to promote urbanization, policy-makers should pay attention to the subjective demands of rural-urban migrants. We suggested that decision- and policy-makers help such migrants improve their social networks and eliminate identity discrimination, so as to encourage their willingness to settle in cities.

RESUMO: Com base nos dados do Laboratório de Dinâmica da Força de Trabalho da China (CLDS) de 2012 e 2014, este artigo usa o modelo de escolha binária do painel para examinar os determinantes das intenções de assentamento de migrantes rurais-urbanos. Os resultados mostram que tanto o senso de pertencimento, quanto a identidade social, desempenham papéis importantes na determinação das decisões de assentamentos de migrantes rurais-urbanos. Além destes, salário, educação e saúde também afetam a disposição dos trabalhadores migrantes de se estabelecerem em uma determinada área. Portanto, a fim de promover a urbanização, os formuladores de políticas devem prestar atenção às demandas subjetivas dos migrantes rurais-urbanos. Sugerimos que autoridades e formuladores de políticas públicas ajudem esses migrantes a melhorar sua rede social e a eliminar a discriminação de identidade, de modo a incentivar sua disposição de se estabelecer nas cidades.
