Social Work Intervention of Stranded Patients from the Ecosystem Perspective: Based on the Clinical Case Record Analysis of Social Work Department in Shanghai D Hospital / 中国医学伦理学

Based on the service of stranded patients in D Hospital, this study aimed to explore the multiple needs of stranded patients and construct an intervention mode from the ecosystem perspective. Using the method of case study, taking the service of stranded patients in hospital D as an example, 49 case records and verbatim interviews with stakeholders were analyzed. The discharge and resettlement of stranded patients faces multiple obstacles from individuals, families, medical and social systems. This study constructed the social work intervention model from the ecosystem perspective: information collection and needs assessment, empowerment of individual system, reconstruction of family support system, coordination of medical system and linking social support system. The intervention process achieved efficient effects. Social work intervention of stranded patients should pay attention to patients’ psychosocial needs and improve awareness of system difficulties; mobilize the multi-system support network and deliver services in combination with case management method; conduct social advocacy for the breakthrough of law and policy.

Efficacy of Citrullus colocynthis seed extract on Earias vittella, Fabricius, (Lepidoptera: Noctuidae): environment sustainable approach

Abstract Earias vittellaFabricius, 1794 (Noctuidae: Lepidoptera) is deliberated to be one of the most destructive pests of cotton and okra vegetation in the world including Asia. The pest has established resistance to various synthetic insecticides. The use of bio-pesticide is one of the unconventional approaches to develop a vigorous ecosystem without harming non- target pests and beneficial natural insect fauna. In the present study, the toxicity levels of Citrullus colocynthis seed extract have been evaluated against the populations of E. vittellaunder standardized laboratory conditions. The toxic effects of C. colocynthis on development periods, protein contents and esterase activity of the life stages of E. vittella were also evaluated. The toxicity levels of methanol, ethanol, hexane, water and profenofos were evaluated on the 1st instar larvae of E. vittella. LC30 and LC80 concentrations exhibited the effectiveness of methanol-based C. colocynthis seed extract against 1st instar larvae of E. vitella. The enhanced larval and pupal periods were revealed in treated samples during the comparison with untreated samples. The intrinsic rate of increase, net reproductive rate in the LC30 and LC80 concentrations exposed larvae remained less than the control treatment. Fecundity, the esterase activity and protein contents were declined in LC30 and LC80 treated samples as compared to the control. The present findings suggest that C. colosynthis extracts based botanical insecticides are beneficial, ecosystem sustainable and can be integrated with insect management programs from environment safety perspective.

Resumo Earias vittella Fabricius, 1794 (Noctuidae: Lepidoptera) é considerada uma das pragas mais destrutivas de algodão e quiabo no mundo, incluindo a Ásia. Essa praga estabeleceu resistência a vários inseticidas sintéticos. O uso de biopesticidas é uma das abordagens não convencionais para desenvolver um ecossistema saudável sem prejudicar as pragas não alvo e a fauna natural benéfica de insetos. No presente estudo, os níveis de toxicidade do extrato de semente de Citrullus colocynthis foram avaliados nas populações de E. vittella em condições de laboratório padronizadas. Os efeitos tóxicos de C. colocynthis nos períodos de desenvolvimento, conteúdo de proteína e atividade esterase das fases de vida de E. vittella também foram avaliados. Os níveis de toxicidade de metanol, etanol, hexano, água e profenofós foram avaliados em larvas de 1º instar de E. vittella. As concentrações de LC30 e LC80 apresentaram eficácia do extrato de sementes de C. colocynthis à base de metanol contra larvas de 1º instar de E. vittella. Os períodos larval e pupal aumentados foram revelados nas amostras tratadas durante a comparação com as amostras não tratadas. A taxa intrínseca de aumento e a taxa reprodutiva líquida nas concentrações de larvas expostas LC30 e LC80 permaneceram menores do que o tratamento controle. A fecundidade, a atividade da esterase e o conteúdo de proteína diminuíram nas amostras tratadas com LC30 e LC80 em comparação com o controle. As presentes descobertas sugerem que os extratos de C. colocynthis à base de inseticidas botânicos são benéficos, sustentáveis para o ecossistema e podem ser integrados com programas de manejo de insetos do ponto de vista da segurança ambiental.

A saúde na região do Médio Solimões no estado do Amazonas: a centralidade de Tefé / Health in the Middle Solimões region, state of Amazonas: the centrality of Tefé

RESUMO Em um cenário de várzea amazônica com fluxos fluviais, o estudo analisa a articulação da Atenção Básica com a Atenção Especializada, buscando discutir as condições políticas e geográficas que impactam na conformação da rede assistencial em uma região de saúde na Amazônia Ocidental. Adotouse uma combinação de estratégias metodológicas: levantamento de indicadores de morbidade e da rede de saúde, mapeamento dos trajetos intermunicipais, levantamento de despesas em Ações e Serviços Públicos de Saúde e entrevistas com gestores. O município de Tefé concentra serviços bancários, poder judiciário, educacional, órgãos de controle e segurança que lhe conferem uma centralidade de funções. Contudo, a saúde não considera os fluxos existentes no território para definição de quais municípios têm Tefé como referência. A defasagem dos dados nos sistemas de informação em saúde, aliada a ausência do ente estadual no planejamento regional de saúde, apoio para provimento de profissionais especializados, pagamento de insumos e organização do fluxo de referência-contrarreferência na rede têm sido desafios para planejar integralidade da atenção na região, sobrecarregando o município-polo. Apesar do aumento progressivo de despesas em saúde nos municípios analisados, a oferta de serviço para além da Atenção Básica permanece sendo um desafio para o Sistema Único de Saúde (SUS) na Amazônia.

ABSTRACT In an Amazonian floodplain scenario with river flows, the study analyzes the articulation of Primary Care with Specialized Care, seeking to discuss the political and geographical conditions that impact on the formation of the care network in a health region in the Western Amazon. A combination of methodological strategies was adopted: survey of morbidity indicators and the health network, mapping of intercity routes, survey of expenses in Public Health Actions and Services and interviews with managers. Tefé concentrates banking services, judiciary branch, education and security bodies that give it a centrality of functions. However, health does not consider existing flows in the territory to define which municipalities have Tefé as a health reference. Outdated data in the health information systems, combined with the absence of the state government in the regional health planning, support to provide specialized professionals, payment for supplies and the organization of referral-counter-referral flow in the network have been challenges for integrality of the attention in the region, overloading the hub municipality. Despite the progressive increase in health expenses in the analyzed municipalities, the provision of services beyond Primary Care remains a challenge for the Unified Health System (SUS) in the Amazon.

Caracterización molecular del dominio de la hélice del gen k13 de Plasmodium falciparum en muestras de comunidades nativas de Condorcanqui, Amazonas, Perú / Molecular characterization of the Plasmodium falciparum k13 gene helix domain in samples from native communities of Condorcanqui, Amazonas, Perú

Introducción. La resistencia de Plasmodium falciparum a diferentes fármacos antipalúdicos es un obstáculo para eliminar la enfermedad. El genotipo resistente de P. falciparum a la artemisinina puede evaluarse examinando los polimorfismos en el dominio de la hélice del gen Pfk13. La Organización Mundial de la Salud recomienda utilizar estas mutaciones como marcadores moleculares para detectar la resistencia a la artemisinina en países donde la malaria por P. falciparum es endémica. Objetivo. Identificar mutaciones relacionadas con la resistencia a artemisinina presentes en el dominio de la hélice del gen k13 de P. falciparum. Materiales y métodos. Mediante la detección pasiva de casos, se recolectaron 51 muestras positivas por microscopía para Plasmodium, provenientes de seis comunidades del distrito de Río Santiago en Condorcanqui, Amazonas. Se realizó la confirmación molecular de la especie mediante PCR en tiempo real y el dominio de la hélice del gen Pfk13 se amplificó y secuenció por electroforesis capilar. Las secuencias obtenidas se compararon con la cepa de referencia 3D7 de fenotipo silvestre. Resultados. Se confirmó un total de 51 muestras positivas para P. falciparum, provenientes de las comunidades de Ayambis, Chapiza, Palometa, Muchinguis, Alianza Progreso y Caterpiza. Después del alineamiento de las secuencias de ADN, se determinó que las muestras no presentaron mutaciones asociadas con resistencia en el gen K13. Discusión. Los resultados obtenidos son coherentes con estudios similares realizados en otros países de Sudamérica, incluyendo Perú. Estos datos proporcionan una línea base para la vigilancia molecular de resistencia a artemisinina en la región Amazonas y refuerzan la eficacia de la terapia combinada con artemisinina en esta área.

Introduction. Resistance of Plasmodium falciparum to different antimalarial drugs is an obstacle to disease elimination. The artemisinin-resistant genotype of P. falciparum can be assessed by examining polymorphisms in the helix domain of the Pfk13 gene. The World Health Organization recommends these mutations as molecular markers to detect artemisinin-resistant in countries where P. falciparum malaria is endemic. Objective. To identify artemisinin resistance-related mutations present in the helix domain of the P. falciparum k13 gene. Materials and methods. We collected a total of 51 samples through passive case detection, positive for Plasmodium by microscopy, from six communities in the district of Río Santiago in Condorcanqui, Amazonas. Molecular species confirmation was performed by real-time PCR and Pfk13 helix domain was amplified and sequenced by capillary electrophoresis. The obtained sequences were compared with the wild type 3D7 reference strain. Results. A total of 51 positive samples were confirmed for P. falciparum from the communities of Ayambis, Chapiza, Palometa, Muchinguis, Alianza Progreso and Caterpiza. DNA sequences alignment showed the absence of resistance-associated mutations in the k13 gene of the collected samples. Discussion. The obtained results are consistent with similar studies conducted in other South American countries, including Perú, so these data provide a baseline for artemisinin- resistance molecular surveillance in the Amazon region and reinforce the efficacy of artemisinin-based combination therapy in this area.

The challenges to control epilepsy in an isolated indigenous tribe in Brazil's Amazon: 15 years of follow-up / Os desafios do controle de epilepsia em indígenas de uma tribo isolada da Amazônia: 15 anos de seguimento

Abstract Background Epilepsy is a common neurological disease that affects people all over the world, but it is rarely described in indigenous peoples. Objective To study the epilepsy characteristics and risk factors for seizure control in people from an isolated indigenous population. Methods This is a retrospective and historical cohort study conducted from 2003 to 2018 (15 years), at a neurology outpatient clinic, of 25 Waiwai tribes' indigenous individuals with epilepsy, inhabitants of an isolated forest reserve in the Amazon. Clinical aspects, background, comorbidities, exams, treatment, and response were studied. Factors that impacted seizure control over 24 months were identified using Kaplan-Meier curves and Cox and Weibull regression models. Results The majority of cases started in childhood, with no difference regarding gender. Focal epilepsies were predominant. Most patients had tonic-clonic seizures. A quarter of them had a family history, and 20% had referred febrile seizures. There was intellectual disability in 20% of patients. Neurological examination and psychomotor development were altered in one third of the participants. The treatment controlled 72% of the patients (monotherapy in 64%). Phenobarbital was the most prescribed anti-seizure medication, followed by carbamazepine and valproate. The most relevant factors that impacted seizure control over time were abnormal neurological exam and family history. Conclusion Family history and abnormal neurological exam were predicted risk factors for refractory epilepsy. Even in an isolated indigenous tribe, the partnership between the indigenous people and the multidisciplinary team ensured treatment adherence. The public healthcare system must guarantee modern anti-seizure medications, mainly for this vulnerable population, which has no other source of treatment.

Resumo Antecedentes A epilepsia é uma doença neurológica que afeta povos do mundo todo, mas raramente é descrita em povos indígenas. Objetivos Estudar as características da epilepsia e os fatores de risco para o controle das crises em pessoas de uma população indígena isolada. Métodos Este é um estudo de coorte retrospectivo e histórico, conduzido de 2003 a 2018 (15 anos) no ambulatório de neurologia, de 25 indígenas Waiwai com epilepsia, habitantes de uma reserva florestal na Amazônia. Aspectos clínicos, antecedentes, comorbidades, exames, tratamento e resposta foram estudados. Identificou-se os fatores que afetaram o controle das crises ao longo de 24 meses usando curvas de Kaplan-Meier e modelos de regressão de Cox e Weibull. Resultados A maioria dos casos teve início na infância, sem diferença quanto ao gênero. Predominavam as epilepsias focais. A maioria dos pacientes apresentava crises tônico-clônicas. Um quarto deles tinha história familiar e 20% referiram convulsões febris. Vinte por cento dos pacientes apresentava deficiência intelectual. Um terço tinha exame neurológico e desenvolvimento psicomotor alterados. O tratamento controlou 72% dos pacientes (monoterapia em 64%). Fenobarbital foi o medicamento mais prescrito, seguido por carbamazepina e valproate, e os fatores que mais impactaram o controle das crises ao longo do tempo foram exame neurológico anormal e história familiar. Conclusão História familiar e exame neurológico anormal foram fatores de risco preditores para epilepsia refratária. Mesmo em uma tribo indígena isolada, a parceria entre os indígenas e a equipe multidisciplinar garantiu a adesão ao tratamento. O sistema público de saúde deve garantir medicamentos modernos anticrise, principalmente para essa população vulnerável, que não tem outra fonte de tratamento.

¿El área verde o el humedal afectan el precio de la vivienda, en un sector de Bogotá?

Diferencias en las características de la infraestructura verde pueden variar la relación entre los espacios verdes urbanos y el precio de la vivienda (PV). El objetivo de este estudio es estimar el efecto de la proximidad de áreas verdes con diseño antrópico (AVDA) y de un humedal, sobre los valores del mercado de vivienda. Mediante uso de sistemas de información geográfica se determinó el tamaño de áreas verdes próximas al humedal y otros atributos de localización de las viviendas; los precios de los inmuebles se obtuvieron en el mercado de finca raíz en Bogotá. Con mínimos cuadrados ordinarios se relacionó el PV con atributos ambientales, de localización y socioeconómicos; el Índice de Moran, modelos de contigüidad y error espaciales permitieron analizar la dependencia espacial de los datos. El AVDA y no el humedal, estuvo significativamente asociada con el PV Las regresiones realizadas mostraron la ausencia de dependencia espacial entre los datos, así como una asociación positiva del PV con las AVDA, el área del inmueble y el número de alcobas. Mientras que la edad de las viviendas y la distancia al Comando de Atención Inmediata (CAI) tuvieron una asociación negativa con el PV. Estos resultados muestran que los residentes locales pagan más por vivir cerca a áreas con AVDA y tienen implicaciones para la planificación urbana de estratos socioeconómicos altos. Los valores estimados en este trabajo pueden ser utilizados para alimentar un análisis costo-beneficio en evaluaciones para la construcción, ampliación y rehabilitación de espacios verdes urbanos. Se recomienda realizar un estudio semejante, en vecindarios de menores ingresos económicos que permitan definir también la tipología de AVDA factible de pagar y que al mismo tiempo proporcione servicios ecosistémicos culturales.

Differences in the characteristics of green infrastructure can vary the relationship between urban green spaces and housing prices. The objective of this study is to estimate the effect of the proximity of anthropically designed green areas and a wetland on housing market values. Using geographic information systems, the size of green areas near the wetland and other attributes of housing location were determined; property prices were obtained from the real estate market in Bogota. Ordinary least squares was used to relate the housing prices to environmental, location and socioeconomic attributes; the Moran Index, contiguity models and spatial error models were used to analyze the spatial dependence of the data. The anthropically designed green areas, and not the wetland, was significantly associated with the housing prices. The regressions performed showed the absence of spatial dependence among the data, as well as a positive association of housing prices with anthropically designed green areas, property area and number of alcoves. While the age of the dwellings and the distance to the Immediate Attention Command had a negative association with housing prices. These results show that local residents pay more to live near areas with anthropically designed green areas and have implications for urban planning for high socioeconomic strata. The values estimated in this work can be used to feed a cost-benefit analysis in evaluations for the construction, expansion, and rehabilitation of urban green spaces. It is recommended that a similar study be conducted in lower income neighborhoods to define the type of anthropically designed green areas that can be afforded and at the same time provide cultural ecosystem services.

As diferenças nas características da infra-estrutura verde podem variar a relação entre o espaço verde urbano e os preços da habitação (PH). O objetivo deste estudo é estimar o efeito da proximidade de áreas verdes antropogenicamente projetadas (AVAP) e de um pântano sobre os valores do mercado imobiliário. Usando sistemas de informação geográfica, foi determinado o tamanho das áreas verdes próximas ao pântano e outros atributos de localização habitacional; os preços dos imóveis foram obtidos do mercado imobiliário em Bogotá. Os mínimos quadrados comuns foram usados para relacionar a PV aos atributos ambientais, de localização e sócio-econômicos; os modelos do Índice Moran, contiguidade e erro espacial foram usados para analisar a dependência espacial dos dados. A AVAP e não a zona úmida, foi significativamente associada à PV. As regressões mostraram a ausência de dependência espacial entre os dados, bem como uma associação positiva de PH com AVAP, área da propriedade e número de alcovas. Enquanto a idade das moradias e a distância até o Comando de Atenção Imediata (CAI) tinham uma associação negativa com o PV Estes resultados mostram que os residentes locais pagam mais para viver perto de áreas com AVAP e têm implicações no planejamento urbano para altos estratos sócio-econômicos. Os valores estimados neste trabalho podem ser usados para alimentar uma análise de custo-benefício em avaliações para a construção, extensão e reabilitação de espaços verdes urbanos. Recomenda-se que seja realizado um estudo semelhante nos bairros de menor renda para também definir o tipo de AVAP que pode ser oferecido ao mesmo tempo em que fornece serviços culturais ecossistêmicos.

Active restoration efforts in the Central Mexican Pacific as a strategy for coral reef recovery

Introduction: The 1997-98 El Niño event caused massive coral bleaching and mortality in the Central Mexican Pacific (CMP). Punta de Mita alone used to harbor more than 30 % of the coral coverage in this region, with a mono-specific Pocillopora coverage. The 1997-1998 ENSO event caused massive coral mortality reducing live coral coverage to < 5 %. Despite being considered a coral region unlikely to recover, recent restoration efforts have been implemented to rehabilitate the coral community. Objective: To assess coral recovery by analyzing the coral growth and survival rates of branching Pocillopora species at Punta de Mita. Methods: Healthy coral fragments of opportunity were re-attached to the natural substrata using zip ties and measured considering their growth in terms of maximum length and width (cm) to determine their annual extension rates. Results: After 50 weeks, corals duplicated their size, with a mean growth of ~ 4 cm year-1. After 100 weeks (2 years), corals triplicated their size, increasing on average 8-9 cm in each diameter. Conclusions: Successful coral reef restoration activities in the Central Mexican Pacific are the result of Pocillopora's physiological processes, such as fast growth rates, and recent life-history traits, like the ability to cope with thermal anomalies, which enable them to thrive in a dynamic region severely affected by natural and anthropogenic perturbations. Indeed, a region considered unlikely to recover has regained its live coral cover from < 5 % in 1998 up to 15 % in 20 years. This demonstrates the importance of assisting natural coral recovery with restoration efforts, especially in coral locations that, despite environmental perturbations, have proven to be resilient and may become coral refugia areas under the current climate change scenario.

Introducción: El evento El Niño de 1997-98 causó un blanqueamiento y mortalidad masiva de corales en el Pacífico Central Mexicano (CMP). Solo Punta de Mita albergaba más del 30 % de la cobertura coralina de esta región, con una cobertura monoespecífica de Pocillopora. El evento ENSO de 1997-1998 causó una mortalidad masiva de corales que redujo la cobertura de corales vivos a < 5 %. A pesar de ser considerada una región de coral con pocas probabilidades de recuperarse, se han implementado esfuerzos de restauración recientes para rehabilitar la comunidad coralina. Objetivo: Evaluar la recuperación de coral analizando el crecimiento coralino y las tasas de supervivencia de especies ramificadas de Pocillopora en Punta de Mita. Métodos: Fragmentos de oportunidad de coral sanos se volvieron a unir a los sustratos naturales usando bridas y se midieron considerando su crecimiento en términos de longitud y ancho máximos (cm) para determinar sus tasas de extensión anual. Resultados : Después de 50 semanas, los corales duplicaron su tamaño, con un crecimiento promedio de ~ 4 cm año-1. Después de 100 semanas (2 años), los corales triplicaron su tamaño, aumentando en promedio 8-9 cm en cada diámetro. Conclusiones: Las actividades exitosas de restauración de arrecifes de coral en el Pacífico Central Mexicano son el resultado de los procesos fisiológicos de Pocillopora, tales como tasas de crecimiento rápido, y rasgos de historia de vida reciente, como la capacidad de hacer frente a anomalías térmicas, que les permiten prosperar en una región dinámica severamente afectada por perturbaciones naturales y antropogénicas. De hecho, esta región que se consideraba poco probable que se recuperara, ha recuperado su cobertura de coral vivo de < 5 % en 1998 hasta 15 % en 20 años. Esto demuestra la importancia de ayudar a la recuperación natural de los corales con los esfuerzos de restauración, especialmente en las ubicaciones de corales que, a pesar de las perturbaciones ambientales, han demostrado ser resistentes y pueden convertirse en áreas de refugio de corales ante el escenario actual de cambio climático.

Epidemiología y características clínicas de las mordeduras de serpientes venenosas en el norte de la Amazonía del Ecuador (2017-2021) / Epidemiology and clinical features of venomous snake bites in the Northern Amazon of Ecuador (2017-2021)

Introducción. En Ecuador, las mordeduras de serpientes venenosas son un problema de salud pública. Sin embargo, no existe información hospitalaria reciente desde la Amazonía. Objetivo. Analizar retrospectivamente las características clínico-epidemiológicas de las mordeduras de serpientes en pacientes ingresados en un hospital de la Amazonía del Ecuador. Materiales y métodos. Se llevó a cabo un estudio transversal en el hospital provincial de Nueva Loja (Sucumbíos), que colinda con Colombia, 2017-2021. La información sobre las variables demográficas, epidemiológicas y clínicas, y la condición al egreso hospitalario, se obtuvieron de la ficha epidemiológica del Ministerio de Salud Pública. Resultados. En cinco años se hospitalizaron 147 pacientes (29,4 por año), sin que se presentaran muertes. Corresponden a 26, 34, 32, 29 y 26 casos, en el 2017, 2018, 2019, 2020 y 2021, respectivamente. Según el sexo, los más afectados fueron los hombres (n=99; 67,3 %), según el grupo etario, los de 21 a 30 años (n=28; 19,0 %) y, según la raza, los de etnia mestiza (n=94; 63,9 %), estudiantes y agricultores. La mediana de edad fue de 28 años (rango: 4 a 81). Hubo mayor prevalencia en abril, junio y septiembre. Todos los accidentes fueron causados por serpientes Viperidae. Veinte (13,6 %) casos fueron leves, 90 (61,2 %), moderados, y 37 (25,2 %), graves. La mordedura fue más frecuente en los pies (45 casos). El 53,1 % recibió suero antiofídico antes de la hospitalización y en el 19,8 % de los pacientes se colocó un torniquete. La mediana de tiempo de llegada al hospital fue de 5 horas (rango: 1-192), y lo más frecuente fue entre 2 y 3 horas (41 casos). No se encontraron diferencias estadísticamente significativas según la gravedad del caso. Conclusiones. Se evidenció una gran prevalencia de mordeduras de serpientes en el norte de la región amazónica-Ecuador, con mayor incidencia en la estación lluviosa y todas causadas por Viperidae. Es importante resaltar la mortalidad nula. Las campañas informativas sobre prevención y primeros auxilios, como la desmotivación del uso de torniquetes, serían fundamentales para reducir los casos, especialmente, en los grupos vulnerables.

Introduction: In Ecuador, poisonous snakebites are a public health problem. However, there is no recent hospital information from the Amazon. Objective: To retrospectively analyse the clinical-epidemiological characteristics of snakebites in patients admitted to a hospital in the Ecuadorian Amazon. Materials and methods: This is a cross-sectional study conducted at the Nueva Loja-Sucumbíos Provincial Hospital, bordering Colombia (2017-2021). Demographic, epidemiological and clinical variables, and condition at hospital discharge, were obtained from the epidemiological file of the Ministerio de Salud Pública. Results: In 5 years, 147 patients (29.4 per year) were hospitalized with no mortality. They corresponded to 26, 34, 32, 29 and 26 cases, in 2017, 2018, 2019, 2020 and 2021, respectively. Men with 99 (67.3%), aged 21-30 years with 28, mixed race with 94 cases, students, and farmers, were the most affected. The most affected (99; 67.3%) were men, people 21 to 30 years-old (28; 19.0%), mestizos (94; 63.9%), students, and farmers. The median age was 28 (range: 4-81) years. Prevalence was higher in April, June, and September. All accidents were caused by Viperidae snakes. Twenty (13.6%) cases were mild, (61.2%) were moderate and 37 (25.2%) were severe. The feet with 45 were the most bitten. Pre-hospitalization anti-venom serum was received by 53.1% and tourniquet by 19.8% patients. Median hospital arrival time was 5 (range 1-192) hours, mostly between 2-3 hours with 41 cases. No statistically significant differences were found considering the severity. Conclusions: A high prevalence of snakebites was evidenced in the north of the Amazon in Ecuador, with a higher incidence in the rainy season and all by Viperidae species. It is important to highlight the null mortality. Information campaigns on prevention and first aid, such as discouraging the use of tourniquets, especially among vulnerable groups.

A cross-sectional survey to assess the drug disposal practices of unused and expired medicines among lay public visiting a tertiary care hospital in an urban metropolis

Objectives: A cross-sectional survey was conducted to evaluate the knowledge, awareness and practice among the lay public regarding storage and disposal of unused and expired medicines. Materials and Methods: This was an observational, cross-sectional, single-centre and questionnaire-based survey. After obtaining Institutional Ethics Committee approval, the study was conducted using a pre-validated structured questionnaire distributed among the lay public visiting a tertiary care hospital located in an urban metropolitan city. Results: Four hundred of 720 individuals visiting the tertiary care hospital participated in the survey. The results revealed that 75% had never referred to any sources to get the correct information about the proper and safe disposal of medicines and had no knowledge regarding the same. About 12.75% of study participants reported that they were educated regarding the disposal of medicines by their treating physicians (RR: 0.71 [95% CI: 0.51–0.99]) when compared with the other sources of information (18%) with statistically significant contribution made by the physicians (p<0.05). About 67% of the public stored their medicines at room temperature. Majority (83.75%) of the study participants reported that they disposed unused and expired drugs in the dustbin. Only 42.5% of the public knew the detrimental effect of improper drug disposal on human health and our ecosystem. In addition, 80% (320/400) of the participants confirmed that, given the option, they would prefer to return the unused or expired drugs to the pharmacy shops from where the medicines were purchased. Conclusion: There is a need to educate drug consumers/general public about safe and proper disposal of unused/ expired medicines. Health-care professionals, governments and policymakers should offer training to educate the general public about Indian regulations for safe disposal of unused/expired medicines.

Payment for ecosystem services (PES): a holistic tool for sustainable forest management-a case study from Pakistan / Pagamento por serviços ecossistêmicos (PES): uma ferramenta holística para o manejo florestal sustentável: um estudo de caso do Paquistão

Abstract Economic valuation of ecosystem services is a new concept in forest management. Economic valuation provides basis for payment for ecosystem services (PES). Therefore, objective of this study was to evaluate eco-tourism and carbon stock services of the Maindam valley, District Swat, Pakistan. For the carbon stock calculation, a sample size of 155 plots of 0.1 hectare (Ha) was taken using preliminary survey at 95% confidence interval and 10% allowable error. The data for tourism services was collected from owners of all the hotels, 100 tourists and key informants of the area at 10% sampling intensity on pretested questionnaire for twenty years period (1997-2017). Results showed that Miandam valley has carbon stock worth US$ 16,306,000 while the value of eco-tourism was US$ 1,578,458 on annual basis. The results also showed that trend of tourism has drastically declined after the 9/11 incident for foreigners and locals and the situation was further deteriorated during the era of Talibanization or militancy from 2008-2011. This study recommends implementation of PES strategy at the rate of 5%, thus a total of US$ 78,922 can be earned from eco-tourism and carbon crediting in the study area annually, which could play important role in sustainable forest management.

Modulative effect of Physalis alkekengi on both gut bacterial and fungal micro-ecosystem / 中草药·英文版

OBJECTIVE@#Gut microbiome is an intricate micro-ecosystem mediating the human health and drug efficacy. Physalis alkekengi (PAL) is an edible and time-honored traditional Chinese medicine. Several pharmacological effects of PAL have been verified and gut bacteria are implied in its therapeutic actions. However, the detailed modulation of PAL on gut bacterial species and on gut fungi remains largely unknown. We, therefore, designed a preliminary experiment in normal mice to reveal the modulation effect of PAL on both gut bacteria and fungi, and explore the interaction between them.@*METHODS@#Herein, the aqueous extract of PAL was orally administrated to normal C57BL/6 mice for four weeks. The full-length 16S rRNA and ITS1/2 gene sequencing were explored to detect the taxa of gut bacteria and gut fungi after PAL treatment, respectively.@*RESULTS@#Oral administration of PAL notably enriched anti-inflammatory bacterial species such as Duncaniella spp. and Kineothrix alysoides, whereas decreased pro-inflammatory species such as Mucispirillum schaedleri. Simultaneously, PAL increased the abundance of gut fungi Aspergillus ochraceus, Cladosporium sp. and Alternaria sp., and decreased Penicillium janthinellum. Correlation network analysis identified two co-existing microbial groups (groups 1 and 2) that were negatively associated with each other. The group 1 comprised PAL-enriched bacteria and fungi, while group 2 was mainly normal chow-enriched bacteria and fungi. In group 1, Antrodia monomitica, Aspergillus clavatus, Mortierella kuhlmanii and Sarcinomyces sp. MA 4787 were positively correlated with Bifidobacterium globosum, Romboutsia ilealis and so on. In group 2, Chaetomium subspirilliferum, Septoria orchidearum and Cephaliophora tropica were positively related to Lactobacillus spp.@*CONCLUSION@#Altogether, this preliminary study first demonstrated the modulation effect of PAL on both gut bacteria and gut fungi, which may shed light on the elucidation of PAL's pharmacological mechanism.

One more place to call home: the invasive bivalve Mytilopsis leucophaeata reaches the Maricá-Guarapina lagoon system (Rio de Janeiro, Brazil) / Mais um lugar para chamar de casa: o bivalve invasor Mytilopsis leucophaeata alcança o sistema lagunar Maricá-Guarapina (Rio de Janeiro, Brasil)

Abstract Mytilopsis leucophaeata is an estuarine bivalve native from the Gulf of Mexico and Southeast USA, and it was introduced in Europe, Asia, Caribbean, South America and Northeast USA, showing massive colonization skills. In Brazil, the single invasion records of M. leucophaeata occur in the city of Rio de Janeiro, i.e., in the Rodrigo de Freitas Lagoon and in the Marapendi Lagoon. We conducted a new series of fieldworks in estuaries from the Rio de Janeiro state in order to evaluate the propagation of this invasive bivalve, aiming sites with proper salinities for the establishment of M. leucophaeata. A new record is given for the Maricá-Guarapina lagoon system, where M. leucophaeata mainly colonizes hard substrata (such as piers and rocks), reaching a mean density up to 43,375 specimens/m2; however, aggregates of M. leucophaeata were also observed in the soft substratum. Based on mitochondrial sequences, the taxonomic identification of the invasive bivalve was confirmed. The associated fauna to the agglomerates of M. leucophaeata in the lagoon system comprises amphipods, barnacles, tanaidaceans, isopods, crabs, polychaetes and snails. The expansion of M. leucophaeata requires a continuous investigation due to the great circulation of boats in the littoral of the Rio de Janeiro state and the increased chance of new introductions.

Resumo Mytilopsis leucophaeata é um bivalve estuarino originário do Golfo do México e Sudeste dos EUA, tendo sido introduzido na Europa, Ásia, Caribe, América do Sul e Nordeste dos EUA, e apresentando massiva capacidade de colonização. No Brasil, os únicos registros de invasão de M. leucophaeata ocorrem no município do Rio de Janeiro, i.e., na Lagoa Rodrigo de Freitas e na Lagoa de Marapendi. Este estudo propõe um novo levantamento de campo em estuários fluminenses para avaliar a propagação desse bivalve invasor, visando locais com salinidade propícia para o estabelecimento de M. leucophaeata. Um novo registro é feito para o complexo lagunar Maricá-Guarapina, onde M. leucophaeata coloniza principalmente substratos duros (como píers e rochas), chegando a uma densidade média de 43.375 indíviduos/m2; porém, agregados de M. leucophaeata também foram observados em substrato inconsolidado. Com base em sequências mitocondriais, a identificação taxonômica do bivalve invasor foi confirmada. A fauna associada aos aglomerados de M. leucophaeata no complexo lagunar compreende anfípodes, cracas, tanaidáceos, isópodes, caranguejos, poliquetas e gastrópodes. A expansão de M. leucophaeata demanda uma investigação contínua devido ao alto fluxo de embarcações no litoral fluminense e elevada probabilidade de novas introduções.
