IDENTIFYING THE ECOTOURISM SUITABILITY SCORE FOR MARINA BEACH AND ELLIOT'S BEACH OF CHENNAI COAST, TAMIL NADU, INDIA.

At the Chennai Coast in Tamil Nadu, India, research is done. Finding out whether Marina Beach and Elliott's Beach are suitable for ecotourism is the study's main goal. For the research using the ecotourism suitability index methodology, land use, land cover, erosion, accretion, beach type, beach width, proximity to bus stop, proximity to train station, and suspended sediment load have all been taken into account. The suitability index of eco tourism is assigned into 4 (four) classes, which are: Class S1 (Highly suitable), Class S2 (Quite Suitable), Class S3 (Suitable with condition) and Class N (Not Suitable). Result of analysis indicates that coast area of Marina Beach and Elliots beach area comes in the class of Highly suitable (S1) by score total of 129 or 95.5 % and 116 or 85.9 % respectively. According to the research, Marina Beach has a sand feature as a land use land cover, 213 metres of beach width, good clarity (500 mg/L), is located 361 metres from a bus stop and 681 metres from a train station, has moderate erosion, and has not experienced any accretion. The beach type is white sand. Likewise, Elliots Beach has a sand feature as a land use land cover, with 222 metres of beach width, good clarity (600 mg/L), 642 metres from the bus stop, and 2351 metres from the railway station, which is high. There is moderate erosion and no accretion, and the sand is of the beach type, which is white. Marina beach has high tourism suitability index as compared to Elliot's beach. By considering marina beach, all the eight parameters are considered to be ne whereas Elliot's beach has far away accessibility this is the main reason for lowering the tourism suitability.

A autora revê o conceito de narcisismo desenvolvido por Freud e o contrapõe ao conceito de individuação de Jung. A partir do mito de Eco e Narciso e seguindo a descrição de C. Byington das funções estruturantes criativas e defensivas, a autora descreve as polaridades narcisismo ­ ecoísmo como funções estruturantes criativas e defensivas. Faz uma releitura do mito desde a normalidade até a desestruturação psicótica das personalidades de Eco e Narciso, dentro da inter-relação criativa-defensiva da polaridade narcisismo-ecoísmo. Conclui citando Jung para ressaltar a importância da relação Eu-Tu no processo de individuação.

The author reviews the concept of narcissism in psychoanalysis contrasting it with Jung's concept of individuation. Starting with the myth of Echo and Narcissus following C. Byington's description of creative and defensive structuring functions, the author describes the narcissismechoism polarity in a similar way. She interprets the myth of Echo and Narcissus from normality to the psychotic reaction of their personalities, within the creative-defensive inter-relationship of the narcissism-echoism polarity. She concludes by quoting Jung to emphasize the importance of the ego-other relationship in the individuation process.

Chemical constituents and strong larvicidal activity of Solanum xanthocarpum among selected plants extracts against the malaria, filaria, and dengue vectors

Background & objectives: The role of mosquitoes is instrumental in the transmission of various diseases. Mosquitoeborne diseases account for a significant share of the global burden of total infectious diseases. Vector control is the principal method for the control of these mosquito-borne diseases. Plant-derived insecticides serve as an effective alternative to chemical insecticides. The present study has been undertaken to assess the larvicidal potential of methanol and petroleum ether extracts of leaves of Solanum xanthocarpum, Parthenium hysterophorus, Manihot esculenta, and Chamaecyparis obtusa. Methods: Larvicidal activity was tested against the early four-stage instar larvae of laboratory-reared susceptible strains of the malaria vector, Anopheles stephensi, dengue fever vector, Aedes aegypti, and the lymphatic filariasis vector, Culex quinquefasciatus at 20 to 120 ppm concentrations. Further, liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectroscopy (GC-MS) analyses were carried out to identify the bioactive compounds present in the methanolic leaf extracts of Solanum xanthocarpum for designing a larvicidal product in future. Results: After 72 h of exposure high larvicidal activities were observed in methanolic and petroleum ether leaves extract of S. xanthocarpum against An. stephensi, Ae. aegypti and Cx. quinquefasciatus. The larvicidal activities for methanol and petroleum ether leaf extract of S. xanthocarpum with LC50 = 09.201 and 12.435 ppm and LC90 = 21.578 and 27.418 ppm for An. stephensi; LC50 = 11.450 and 10.026 ppm and LC90 = 26.328 and 22.632 ppm for Ae. aegypti and LC50 = 12.962 and 13.325 ppm and LC90 = 26.731 and 30.409 ppm for Cx. quinquefasciatus, respectively, were found to be most effective. GC-MS analysis revealed 43 compounds, amongst these phytol (13.09%), 3-allyl-2- methoxy phenol (9.55%), (9Z, 12Z)-9, 12-octadecadienoyl chloride (7.93%), linoleic acid (5.45%), alpha-tocospiro B (5.08%) and hexadecanoic acid (4.35%) were identified as major compounds. Interpretation & conclusion: Present work showed that leaf extracts of S. xanthocarpum are a source of potential natural candidate that possess several phytochemicals which can be explored further for the development of ecologically safer mosquito control products.

Climate awareness, anxiety, and actions among youth: a qualitative study in a middle-income country

Objectives: The impact of climate change on mental health is well established, but few studies have examined the perspectives of young people, especially in low- and middle-income countries (LMICs). In this qualitative study, we explored how Brazilian children and adolescents experience climate change. This approach can help inform environmental education, communication, and self-care strategies for this age group. Methods: We conducted focus groups with 50 children and adolescents aged 5 to 18 years in three locations in Brazil. We analyzed the data using an interpretative phenomenological analysis framework. Results: We identified three profiles of involvement with climate change: unaware, disengaged, and engaged. Profiles were largely related to different socioeconomic contexts. We analyzed each profile across the dimensions of space, time, emotions, and actions. Adults were portrayed by participants as stubborn deniers, as neutral influences, or as role models of knowledge and engagement. Due to their age and developmental level, young children had distinctive perceptions of climate change. Conclusion: Spatial and temporal perceptions of climate change are a key element for experiencing and engaging with environmental concerns and vary according to age and socioeconomic differences. Effective communication to foster climate action at individual and collective levels requires narratives that reach different ages. Replication of these findings in other LMICs is warranted.

Abstract Studies in pharmacological and ecopharmacological surveillance make it possible to monitor, identify and minimize harmful effects arising from the use of drugs. Therefore, the present study aimed to describe the current scenario of pharmacoepidemiology and ecopharmacovigilance in Brazil, about the production, registration, marketing, and use of medicines. A systematic survey was carried out through the PubMed/Medline, Lilacs, and SciELO databases, whose theme involved research in pharmacoeconomics, pharmacovigilance, ecopharmacovigilance, and the study of drug use in Brazil from 2001 to 2019. Publications were unevenly distributed between Brazilian regions. Hypertensive patients, cancer patients, and pregnant women were the most cited risk groups, and antimicrobials, psychotropics, and antineoplastics were the most discussed pharmacological groups. Cost of health care was the most discussed topic in the context of pharmacoeconomics and most of the work was aimed at analyzing and obtaining data regarding the use of drugs and their adverse reactions. Regarding ecopharmacovigilance, no publications were found in Brazil covering this area. Despite advances in pharmacoepidemiological legislation and improvements in inspection processes, regarding the surveillance of the production, registration, commercialization, and use of medicines, there are still gaps regarding the contribution of a directed scientific vision, especially to the management and different uses of resources. therapeutic and economic aspects of the Brazilian health system, as well as an environmental vision regarding the use of medicines.

Resumen Los estudios de vigilancia farmacológica y ecofarmacológica permiten controlar, identificar y minimizar los efectos nocivos derivados del uso de los medicamentos. Ante esto, el presente estudio tuvo como objetivo describir el escenario actual de la farmacoepidemiología y la ecofarmacovigilancia en Brasil, en relación con la producción, el registro, la comercialización y el uso de los medicamentos. Se realizó una encuesta sistemática, a través de las bases de datos PubMed/Medline, Lilacs y SciELO, cuya temática involucró investigaciones sobre farmacoepidemiología, farmacovigilancia, ecofarmacovigilancia y estudio del uso de medicamentos en Brasil desde 2001 hasta 2019. Las publicaciones se distribuyeron de forma desigual entre las regiones brasileñas. Los pacientes hipertensos, los pacientes oncológicos y las mujeres embarazadas fueron los grupos de riesgo más citados y los antimicrobianos, los psicotrópicos y los antineoplásicos fueron los grupos farmacológicos más discutidos. El coste de la asistencia sanitaria fue el tema más abordado en el contexto de la farmacoeconomía y la mayoría de los trabajos estaban dirigidos a analizar y obtener datos sobre el uso de los medicamentos y sus reacciones adversas. En cuanto a la ecofarmacovigilancia, no se encontraron publicaciones en Brasil que aborden esta área. A pesar de los avances en la legislación farmacoepidemiológica y de las mejoras en los procesos de inspección, en lo que respecta a la vigilancia de la producción, registro, comercialización y uso de los medicamentos, todavía falta una visión científica dirigida, sobre todo, a la gestión y a los diferentes usos de los recursos terapéuticos y económicos del sistema de salud brasileño, así como una visión ambiental en cuanto al uso de los medicamentos.

BARBARA KINGSOLVER'S FLIGHT BEHAVIOUR: AN ECO FEMINISTIC APPROACH

Literary works express the ideas and feelings of human beings towards the society. They act as a foremost tool in building social construction among the people. The literary works also plays a vital role in the lives of women for their upliftment. They make women to realise their self. One such writer who strives hard to elevate women through her works is Barbara Kingsolver. Though she is an ecologist writer, she concentrates on her women characters by associating them with the natural world. Eco-feminists states that without any liberation to nature there will not be no successful in liberating women from hurdles. In the novel Flight Behaviour Kingsolver portrays Dellarobia's behavioural amelioration in relation with nature. Thus, this paper accounts on Dellarobia's ?ght or ?ight behaviour in search of her own identity

Exposure of Artemia salinato glyphosate and bioremediation by isotherapy

Artemia salina, an ecotoxicity bioindicator, isa microcrustacean belonging to the order Anostraca. Glyphosate is an herbicide widely used to control weeds. However, its intoxication can cause serious damage to human health and the balance of the environment, given its effects as an endocrine disruptor.Objective:verify the possible protection of the artemia exposed to glyphosate by the addition of its isotherapic into water, by means of the evaluation of the behavioral and morphological features of nauplii and of the physical properties of remedies andtreated water, to elucidate the involved mechanisms. Methods:Artemia salinacysts were kept in culture bottles containing artificial seawatercontaining glyphosate at LC 10 (lethal concentration 10%), to promote hatching within 48 hours. The isotherapic preparations were inserted in each bottle in a 10% of the total water volume. Part of the nauplii was distributed in transparent tubes, being 10 nauplii per tube and 6 tubes per group, for behavioral analysis, and part were collected for a detailed morphological analysis, under an optical microscope. About 80 to 270 nauplii were analyzed per group. The reserved water was divided into aliquots for physicochemical analysis, that is, evaluation of the water dipole behavior by Cartwright ́s method.Results:Gly 6cH presented selective effects on nauplii hatching (p=0.02) and on defected/healthy ratio (p=0.001), representing some protective action. This result was dependent of the salinity of water and presented correspondence with the effects on solvatochromic dyes, indicating that charges and ions can be critical factors involved in the mechanism of action. We concluded that the use of isotherapics could be a plausible tool to reduce the environmental impact of the indiscriminate use of glyphosate, since these results can be reproduced in further studies.

Contributions and strategies of eco-agriculture of Chinese medicine services for carbon dioxide peaking and carbon neutrality / 中国中药杂志

Carbon dioxide peaking and carbon neutrality have become hot issues of political and economic activities in China and abroad. The structure and development of various industries in China will be profoundly affected in the process of accomplishing "Dual Carbon" goals. Eco-agriculture of Chinese medicine(EACM) highlights the balance and sustainable development of the ecosystem while producing high-quality medicinal materials. With chemically synthesized fertilizers, pesticides, and growth regulators prohibited, EACM emphasizes the recycling of agricultural and sideline products and the reduction of waste output, which results in the minimal negative impact on the ecological environment. Therefore, it is typical agriculture with low-carbon sources and high-carbon sinks. This study reviewed the mechanism and potential of EACM in carbon dioxide peaking and carbon neutrality, analyzed the specific ways of EACM in reducing carbon sources and increasing carbon sinks based on the typical ecological planting pattern, and proposed the point of view to strengthen EACM as well as the "Dual Carbon" theory and research methods, so as to direct low-carbon and efficient deve-lopment. Furthermore, this study advocated to comprehensively promote the transformation of Chinese medicine production from chemical agriculture to eco-agriculture to improve the comprehensive benefits of contribution rate of carbon neutrality, explore and establish carbon sink compensation mechanism to ensure the sustainable and healthy development of EACM, and strengthen the training of EACM and "Dual Carbon" theory and technologies to continuously improve the capacity of EACM in sustainable development. This study is expected to provide a reference for the development of ecological functions in EACM and the development of economic functions through ecological functions.

Study on the zoonotic cycle of tegumentary leishmaniasis in an endemic area of a metropolitan region in the Northeastern region of Brazil

ABSTRACT This study was conducted to characterize the transmission cycle of the tegumentary leishmaniasis (TL) in an old colonization area at Pernambuco State, Brazil. The aims were to identify autochthonous cases, sandflies fauna, domestic animals as possible reservoir hosts and the Leishmania species involved in this endemic area. A total of 168 suspected human cases of TL and 272 domestic animals (canine, feline, equine, goat, and sheep) were included. The sandflies were captured and identified by species. Patients were predominantly male and the average age was 37+18.1 years old. Of 85 patients who had skin lesions, 25.6% of them had direct positive smears for TL and 34 isolates were identified as Leishmania (Viannia) braziliensis. The confirmation for TL diagnosed by molecular detection (PCR) was almost three times more sensitive than the direct test [p < 0.001; PR = 2.72] associated with clinical examination. The Kappa test on PCR between two different specimens, biopsy, and skin lesion swab was 60.8% (p < 0.001). More than 200 specimens of sandflies (80 males and 159 females) were captured and identified as Lutzomyia whitmani (99.6%) and Lu. evandroi (0.4%). The detection of L. (V.) braziliensis by Real-Time PCR in the blood of a captured fed female was positive in 59.3% of Lu. whitmani. Of the 272 domestic animals included, 61.76% were male (n = 168). Thirty-six animals (13.2%) had lesions compatible with TL (34 dogs, 1 cat and 1 sheep) and 3 of them, all dogs, had lesions on the snout, showing destruction of cartilage and mucosa. The study suggests the participation of domestic animals as possible reservoirs. However, further studies are necessary to better understand the transmission cycle and take recommended measures in order to control the disease.

Trypanosoma cruzi genetic diversity: impact on transmission cycles and Chagas disease

Trypanosoma cruzi, the agent of Chagas disease (ChD), exhibits remarkable biological and genetic diversity, along with eco-epidemiological complexity. In order to facilitate communication among researchers aiming at the characterisation of biological and epidemiological aspects of T. cruzi, parasite isolates and strains were partitioned into seven discrete typing units (DTUs), TcI-TcVI and TcBat, identifiable by reproducible genotyping protocols. Here we present the potential origin of the genetic diversity of T. cruzi and summarise knowledge about eco-epidemiological associations of DTUs with mammalian reservoirs and vectors. Circumstantial evidence of a connection between T. cruzi genotype and ChD manifestations is also discussed emphasising the role of the host's immune response in clinical ChD progression. We describe genomic aspects of DTUs focusing on polymorphisms in multigene families encoding surface antigens that play essential functions for parasite survival both in the insect vector and the mammalian host. Such antigens most probably contributed to the parasite success in establishing infections in different hosts and exploring several niches. Gaps in the current knowledge and challenges for future research are pointed out.

Estudios del despoblamiento rural en Chile: aproximaciones hacia un marco analítico desde la ecología política latinoamericana / Estudos do despovoamento rural no Chile: abordagens para um quadro analítico da ecologia política latino-americana / Studies of rural depopulation in Chile: approaches towards an analytical framework from Latin American political ecology

Resumen El objetivo de este este trabajo fue hacer una revisión documental sobre el despoblamiento rural para ubicar sus principales antecedentes, corrientes y visiones de estudio en Latinoamérica y otros espacios geográficos, con énfasis en Chile para exponer la forma en que la relación entre extractivismo y despoblamiento rural ha sido tratada con la intención de contrastar los resultados con los insumos teóricos de la ecología política latinoamericana y de plantear un análisis integral de este fenómeno. Los resultados muestran que en Chile los factores que han impulsado históricamente el despoblamiento de zonas rurales fueron la dictadura militar, los planes de ordenamiento territorial, industrialización y urbanización, la transformación de la estructura agraria, el cambio climático y el extractivismo. Se constató que los estudios sobre este último factor han omitido la forma en que se produce el despoblamiento, en general en contextos de estructuras de poder desigual y de tensiones territoriales entre distintos modelos de desarrollo y de formas de habitar el espacio. Se propone el campo de la ecología política latinoamericana para abordar los procesos de despoblamiento rural vinculados al extractivismo, cuyos insumos teóricos pueden contribuir a la comprensión más amplia del problema y a la construcción de respuestas con y desde los propios territorios.

Resumo O objetivo deste artigo é realizar uma revisão documental sobre o despovoamento rural para localizar os principais antecedentes, correntes e visões de estudo na América Latina e outros espaços geográficos. A ênfase foi colocada no Chile para expor a forma como tem sido tratada a relação entre extrativismo e despovoamento rural, com a intenção de contrastar os resultados com os aportes teóricos da ecologia política latino-americana e propor uma análise abrangente desse fenômeno. Os resultados mostram que no Chile os fatores que historicamente impulsionam o despovoamento das áreas rurais têm sido a ditadura militar, os planos de ordenamento territorial, a industrialização e a urbanização, a transformação da estrutura agrária, as mudanças climáticas e o extrativismo. Constatou-se que os estudos sobre este último fator têm omitido a forma como ocorre o despovoamento, regularmente em contextos de estruturas de poder desiguais e tensões territoriais entre diferentes modelos de desenvolvimento e formas de habitar o espaço. O campo da ecologia política latino-americana se propõe a abordar os processos de despovoamento rural vinculados ao extrativismo, cujos aportes teóricos podem contribuir para uma compreensão mais ampla do problema e a construção de respostas com e a partir dos próprios territórios.

Abstract The goal was to conduct a documentary review on rural depopulation in order to identify the main antecedents, trends and visions in studies in Latin America and other geographical spaces. Emphasis was placed on Chile to expose the way in which the relationship between extractivism and rural depopulation has been treated, with the intention of contrasting the results with the theoretical inputs of Latin American political ecology and proposing a comprehensive analysis of this phenomenon. Results show that, in Chile, factors historically driving the depopulation of rural areas include the military dictatorship, the territorial ordering plans, industrialization and urbanization, the transformation of the agrarian structure, climate change and extractivism. It was found that studies on this last factor have omitted the way in which depopulation occurs, regularly in contexts of unequal power structures and territorial tensions between different development models and ways of inhabiting space. The field of Latin American political ecology is proposed in order to address the processes of rural depopulation linked to extractivism, since its theoretical inputs can contribute to a broader understanding of the problem and to the construction of responses with and from the territories themselves.

Yield， Quality， and Soil Microecology of Panax ginseng Under Different Forests / 中国实验方剂学杂志

ObjectiveTo explore the forest type and soil environment suitable for Panax ginseng. MethodThe yield， quality， soil chemical properties， soil enzyme activity， and soil microbial metabolism of 9-year-old P. ginseng under different forests were investigated. ResultThe quality of P. ginseng was significantly different among forest types. To be specific， P. ginseng under the Quercus mongolica forest had the highest quality， with the total saponin content of 2.27% which was 51.89% higher than that in P. ginseng under Larix gmelinii forest. The yield of P. ginseng under Q. mongolica forest and L. gmelinii forest （30 g·m-2） was the highest， 62.5% higher than that under Betula platyphylla forest. The soil content of organic matter， Cu， and Zn， and activity of sucrase and urease under Q. mongolica forest were lower than those under other forest types. The utilization rate of D-galacturonic acid by soil microorganisms under Q. mongolica forest was higher than that under other forest types， but the utilization rate of L-phenylalanine was lower than that under other forest types. The utilization rate of 2-hydroxybenzoic acid by soil microorganisms of B. platyphylla forest was significantly lower than that under other forest types. There was a negative correlation between soil Zn and ginsenoside Rb1 and Rc， and between soil K and ginsenoside Rb2 and Rb3. Mn and Cu were positively correlated with most saponins. The results of redundancy analysis showed that the soil microorganisms using carbon sources of amino acids， esters， acids， and sugars were the main factors causing the differences in P. ginseng among different forest types. ConclusionThe yield and quality of P. ginseng under Q. mongolica forest were the best， followed by the forest with different tree species， and coming in last was the B. platyphylla forest.

ObjectiveTo investigate the effects of exogenous Fusarium oxysporum and Trichoderma viride on the diversity of soil fungal community and carbon metabolic function of cultivated Panax ginseng. MethodIllumina HiSeq 2500 high-throughput sequencing combined with Biolog-ECO was used to analyze the species diversity and functional diversity of soil fungal communities in P. ginseng soil under different exogenous treatments. ResultThe results of high-throughput sequencing showed that the number and species of microorganisms in the soil were significantly changed after exogenous microorganisms were added. The soil fungi with relative abundance greater than 1% included Mortierella sp.，Fusarium sp.，Humicola sp.，and Simplicillium sp. Mortierella sp. in each treatment group significantly increased. Humicola sp. and Simplicillium sp. could be induced to increase by exogenous addition of F. oxysporum，while T. viride at a high concentration could significantly inhibit the growth of F. oxysporum. As revealed by Biolog and principal component analysis （PCA），the average well color development （AWCD） in the high-dose T. viride group （MG） was significantly higher than that in the control group （QS）and the low-dose F. oxysporum group（LD）. The utilization abilities for amino acids，carboxylic acids，polymers， and amines were enhanced in the MG group，but the microbial metabolic activity was reduced in the high-dose F. oxysporum group （LG）. There was no significant increase in the utilization of phenolic acids by soil microorganisms in both groups. ConclusionExogenous addition of F. oxysporum can lead to the growth and reproduction of other pathogenic fungi. Exogenous addition of T. viride can enhance the soil fungal community structure and metabolic diversity，inhibit the proliferation of F. oxysporum，and improve the soil microbial environment of cultivated P. ginseng.

Chamado de Eco: a escuta de vozes silenciadas / Echo's Calling: listening to silenced voices / Llamada del Eco: la escuta de voces silenciadas

O presente trabalho tem por objetivo dar atenção a vozes silenciadas. Pelo levantamento de estudos em Psicologia Analítica sobre a figura mitológica de Eco e de Estudos Literários que correlacionam silenciamento e psicologia, buscou-se compreender o que leva ao silenciamento imposto. Foi possível compreender que o olhar hegemônico para Eco e para o Outro os coloca numa posição de pouco valor, algo também encontrado em discursos de resistência e narrativas testemunhais na área da Literatura, especialmente quando o encontro com o Outro parece ser ameaçador.

The present study aims to pay attention to silenced voices. By surveying studies in Analytical Psychology about the mythological figure of Echo and Literary Studies that correlate silencing and psychology, we sought to understand what leads to imposed silencing.It was possible to understand that looking at Echo e the Other through hegemonic lenses places them in a position of little worth and value, something that also appeared in resistance speech and testimonial narratives in the field of Literature, especially when the encounter with the Other seems to be threatening.

Utilidad de la ecografía y del eco-doppler color en pacientes de alto riesgo obstétrico / Usefulness of ultrasound and color Doppler ultrasound in high-risk obstetric patients / Utilidade do ultrassom e do ultrassom Doppler colorido em pacientes obstétricas de alto risco

Resumen: La ecografía obstétrica, nos permite determinar con adecuada precisión la biometría fetal y realizar el seguimiento de su curva de crecimiento en función de la edad gestacional. El Eco-Doppler Feto-Placentario, permite el estudio del flujo sanguíneo materno-fetal y de la circulación placentaria de forma no invasiva, inocua y reproducible. Su eficacia ha sido demostrada en el control del embarazo de alto riesgo obstétrico, logrando una reducción de la mortalidad perinatal del 49%. El mismo evalúa la circulación útero - placentaria (arterias uterinas y arteria umbilical), la circulación fetal arterial (arteria cerebral media) y la venosa (Ductus Venoso, Vena Cava Inferior, Vena Umbilical). Identificar el grupo de pacientes con trombofilia, que requieren un control ecográfico más estricto es fundamental para lograr el beneficio con el tratamiento médico.

Abstract: Obstetric ultrasound allows us to determine with adequate precision the fetal biometry and to monitor its growth curve based on gestational age. The Feto-Placental Eco-Doppler allows the study of maternal-fetal blood flow and placental circulation in a non-invasive, safe and reproducible way. Its efficacy has been demonstrated in the control of high-risk obstetric pregnancy, achieving a 49% reduction in perinatal mortality. It evaluates the uterine-placental circulation (uterine arteries and umbilical artery), the fetal arterial circulation (middle cerebral artery) and the venous circulation (Ductus Venoso, Inferior Vena Cava, Umbilical Vein). Identifying the group of patients with thrombophilia, who require stricter ultrasound control is essential to achieve benefit with medical treatment.

Resumo: A ultrassonografia obstétrica permite determinar com precisão adequada a biometria fetal e monitorar sua curva de crescimento com base na idade gestacional. O Eco-Doppler Feto-Placental permite o estudo do fluxo sanguíneo materno-fetal e da circulação placentária de forma não invasiva, segura e reprodutível. Sua eficácia foi demonstrada no controle da gravidez obstétrica de alto risco, alcançando uma redução de 49% na mortalidade perinatal. Avalia a circulação útero-placentária (artérias uterinas e artéria umbilical), a circulação arterial fetal (artéria cerebral média) e a circulação venosa (Canal Venoso, Veia Cava Inferior, Veia Umbilical). Identificar o grupo de pacientes com trombofilia, que necessita de controle ultrassonográfico mais rígido, é essencial para obter benefício com o tratamento médico.
