Abstract Objective: To compare population characteristics and placental findings associated with stillbirth, in women with asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection at the time of delivery. Materials and methods: Analytical cross-sectional study women with a diagnosis of stillbirth and with asymptomatic SARS-CoV-2 infection. Patients with gynecological pathology and those with more than one RT-PCR test were excluded. Results: There is no statistically significant difference between patients with asymptomatic SARS-CoV-2 infection compared to patients without infection for population characteristics such as maternal age, obstetric history, gestational age, education, marital status, smoking habit, chronic-degenerative diseases. There was no difference in placental findings of chorioamnionitis, vasculitis, deciduitis, thrombosis, acute atherosis, and fibrinoid necrosis. Conclusions: There is no statistically significant difference in the population and placental characteristics, in pregnant women diagnosed with stillbirth with and without confirmed asymptomatic SARS-CoV-2 infection. For the moment, we have insufficient data to affirm any population characteristic associated with stillbirth in patients with asymptomatic SARS-CoV-2 infection.

Resumen Objetivo: Comparar características poblacionales y hallazgos placentarios asociados a óbito, en mujeres con infección asintomática por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) al momento de la resolución del embarazo. Material y métodos: Estudio transversal analítico, mujeres con diagnóstico de óbito e infección asintomática por SARS-CoV-2. Se excluyeron pacientes con patología ginecológica y aquellas con más de una prueba RT-PCR. Resultados: No hay diferencia estadísticamente significativa entre las pacientes con infección asintomática por SARS-CoV-2 comparadas con pacientes sin infección para las características poblacionales como edad materna, antecedentes obstétricos, edad gestacional, escolaridad, estado civil, hábito tabáquico y enfermedades crónico-degenerativas. Tampoco hubo diferencia en los hallazgos placentarios de corioamnionitis, vasculitis, deciduitis, trombosis, aterosis aguda y necrosis fibrinoide. Conclusiones: No hay diferencia estadísticamente significativa en las características poblacionales y placentarias en embarazadas con diagnóstico de óbito, con y sin infección asintomática por SARS-CoV-2. Tenemos datos insuficientes para afirmar alguna característica asociada a óbito en pacientes con infección por SARS-CoV-2 asintomática.

ABSTRACT Background: We investigated the time to death and factors associated with deaths from dengue and chikungunya during the first epidemic after the introduction of the chikungunya virus in Northeastern Brazil. Methods: This retrospective cohort study was conducted in Pernambuco between 2015 and 2018. Logistic regression was used to identify independent risk factors. The probability of survival among individuals with different arbovirus infections was estimated and the survival curves were compared using log-rank tests. Results: The lethality coefficients for dengue and chikungunya viruses were 0.08% and 0.35%, respectively. The chance of death due to chikungunya infection increased progressively from the age of 40 years. At 40-49 years, the odds ratio was 13.83 (95%CI, 1.80-106.41). At 50-59 years and 60 years or older, the odds ratio was 27.63 (95%CI, 3.70-206.48); and 78.72 (95%CI, 10.93-566.90), respectively. The probability of death associated with dengue virus infection increased from the age of 50 years. Among patients aged 50-59 years and 60 years or older, the odds ratio was 4.30 (95%CI, 1.80-10.30) and 8.97 (95%CI, 4.00-20.0), respectively. Independent factors associated death were headache and age of 50 years or older for dengue; and headache, nausea, back pain, intense arthralgia, age 0-9 years or 40 years and older, and male sex for chikungunya. The ratio between mortality rates revealed that the time to death from dengue was 2.1 times faster than that from chikungunya (95%CI, 1.57-2.72). Conclusions: The time to death was shorter in patients with dengue than in those with chikungunya disease. This study reinforces the need for faster and more effective decision-making in public health services to enhance patient outcomes and minimize mortality.

Abstract Background: Gut microbiota is a complex organized collection of microorganisms that confers multiple metabolic advantages to the host. The reduced diversity and proportion of specific gut microbial species have been associated with obesity and metabolic disorders. Multidimensional interventions, including modifications in dietary and physical activity habits, are associated with favorable changes in microbiota composition. This pilot study aimed to evaluate changes in the gut microbiota composition of Mexican children with obesity before and after a 6-week multidimensional intervention. Methods: Blood and stool samples were collected, and anthropometric measurements were obtained from six children with obesity before and after the intervention. The intervention consisted of modeling a hypo energetic diet and giving nutritional and physical activation recommendations. DNA from stool samples was used to characterize gut microbial composition by sequencing the 16S rRNA gene. Results: The decrease in waist circumference was associated with increased Odoribacter relative abundance. However, gut microbiota composition and diversity remained unchanged. Conclusions: Although no modifications in the body mass index, body fat, composition, or diversity of the gut microbiota were observed with the intervention, it was possible to associate the reduction in waist circumference with the presence of Odoribacter after a multidimensional intervention in Mexican children with obesity.

Resumen Introducción: La microbiota intestinal es un conjunto de microorganismos organizados de forma compleja que confieren múltiples ventajas metabólicas al hospedero. La reducida diversidad y la proporción de ciertas especies sobre otras se ha asociado con obesidad y enfermedades metabólicas. Las intervenciones multidimensionales, que incluyen modificaciones en los hábitos alimentarios y de actividad física, se asocian con cambios favorables en la composición de la microbiota. El objetivo de este estudio piloto fue evaluar la composición de la microbiota intestinal de niños mexicanos con obesidad, antes y después de una intervención multidimensional de seis semanas de duración. Métodos: Se tomaron muestras de sangre y de heces y se realizaron las mediciones antropométricas de seis niños con obesidad, antes y después de la intervención. La intervención consistió en modelar una dieta hipoenergética y dar recomendaciones nutricias y de actividad física. A partir del DNA de las muestras de heces se realizó la caracterización de la microbiota intestinal por secuenciación del gen 16S del RNAr. Resultados: La disminución de la circunferencia de cintura se asoció con un aumento en la abundancia del género Odoribacter. Sin embargo, no se encontraron cambios en la composición de la microbiota intestinal. Conclusiones: A pesar de que la intervención no modificó el índice de masa corporal, masa grasa, composición ni diversidad de la microbiota intestinal, sí se logró asociar la reducción de la circunferencia de cintura con la abundancia de Odoribacter en el presente estudio piloto en niños mexicanos con obesidad.

Abstract: Introduction: Medical literature has huge information on studies and guidelines for patients with coronary, peripheral, or structural interventional procedures; nonetheless, a few papers focused on optimal fasting time, hydration, contrast dye used, post-intervention discharge monitoring in-home, ward, or intensive care unit as vascular complications. This paper review aims to provide achievable facts that aid physicians in protecting patients’ integrity in hospitals and homes.

Resumen: Introducción: Existe una vasta información en la literatura médica de los procedimientos coronarios, estructurales y periféricos en diversos estudios y guías, sin embargo, pocos documentos abordan temas como tiempo óptimo de ayuno, hidratación, cantidad de medio de contraste, monitoreo del paciente después del procedimiento; cuándo puede ir a casa, al área de hospitalización, a terapia intensiva o unidad coronaria y las posibles complicaciones vasculares. Este manuscrito de revisión contiene datos que ayudarán a los médicos a ser vigilantes de la integridad de los pacientes en hospitales y sus hogares.

The aim of this study is to analyze home food (in)security via intersectionality. The data are from the cross-sectional study Quality of the Urban Environment of Salvador - QUALISalvador, conducted from 2018 to 2020 in Salvador, Bahia State, Brazil. A structured questionnaire and the Brazilian Food Insecurity Scale were used. A total of 14,713 households were analyzed. The outcome variable was the situation of food security: mild, moderate, or severe food insecurity. The exposure of interest variable was the intersection of the variables self-declared race/color and gender: white man, white woman, black man, black woman. Multinominal logistic regression models were used to estimate the association between exposure of interest and outcome, adjusted for socioeconomic variables and stratified according to education level and per capita family income. Households lead by black women had a higher chance of experiencing mild (OR = 1.39; 95%CI: 1.15-1.68; p = 0.001) and moderate or severe (OR = 1.94; 95%CI: 1.49-2.52; p < 0.001) food insecurity in relation to households lead by white men. They also had a higher chance of experiencing moderate or severe food insecurity in all levels of education and in the ranges of up to 1/2 minimum wage and > 1 minimum wage. When the person responsible for the household was a black man, the greatest chance for this condition was in the > 1 minimum wage. Food insecurity in households lead by black women, even in socioeconomically favorable conditions, is revealed as one of the consequences of the structural interaction of racism and sexism.

Este trabalho objetiva analisar a (in)segurança alimentar domiciliar sob o olhar da interseccionalidade. Para isso, foram analisados 14.713 domicílios, utilizando-se um questionário estruturado e a Escala Brasileira de Insegurança Alimentar, além dos dados do estudo transversal Qualidade do Ambiente Urbano de Salvador - QUALISalvador, realizado entre 2018 e 2020 em Salvador, Bahia, Brasil. A variável desfecho foi a situação de segurança alimentar (insegurança alimentar leve, moderada ou grave) e a variável exposição de interesse foi o cruzamento de raça/cor e sexo autodeclarado (homem branco, mulher branca, homem negro, mulher negra). Modelos de regressão logística multinominal foram usados para estimar a associação entre a exposição de interesse e o desfecho, ajustada a partir de questões socioeconômicas estratificadas segundo escolaridade e renda familiar per capita. Diante disso, concluiu-se que domicílios chefiados por mulheres negras apresentaram maior chance de insegurança alimentar leve (OR = 1,39; IC95%: 1,15-1,68; p = 0,001) e moderada ou grave (OR = 1,94; IC95%: 1,49-2,52; p < 0,001) em relação aos domicílios chefiados por homens brancos, além de maior chance de insegurança alimentar moderada ou grave em todos os níveis de escolaridade e nas faixas de até 1/2 salário mínimo e > 1 salário mínimo. Quando os responsáveis foram homens negros, a maior chance se apresentou na faixa > 1 salário mínimo. A insegurança alimentar nos domicílios chefiados por mulheres negras, mesmo em condições socioeconomicamente favoráveis, revela-se como uma das consequências da interação estrutural do racismo e do sexismo.

O objetivo deste estudo foi apresentar a prevalência da insegurança alimentar domiciliar em diferentes territórios da cidade de Salvador, Bahia, Brasil, e analisar fatores demográficos e socioambientais a ela associados. Os dados utilizados são de uma pesquisa maior denominada Qualidade do Ambiente Urbano de Salvador - QUALISalvador, realizada entre 2018 e 2020 em Salvador. A insegurança alimentar foi avaliada por meio da Escala Brasileira de Insegurança Alimentar. Foram analisados 15.171 domicílios. Modelos de regressão logística multinominal foram utilizados para analisar a associação de variáveis demográficas e socioambientais com insegurança alimentar leve (IAL) e moderada ou grave (IAMG), para Salvador e macrozonas. Salvador apresentou 40,96% de insegurança alimentar. Nas macrozonas, as prevalências se diferenciaram: Orla Atlântica (25,8%), Área Urbana Consolidada (33%), Subúrbio (45,7%) e Miolo (47,9%). Todos os fatores analisados apresentaram associação com IAL e/ou IAMG no modelo para Salvador, entre eles estão o responsável pelo domicílio ter escolaridade ≤ 4 anos (IAL: OR = 2,00; IC95%: 1.61-2,47/IAMG: OR = 4,94; IC95%: 3,83-6,35), renda familiar per capita de até 1/2 salário mínimo (IAL: OR = 2,62; IC95%: 2,37-2,93/IAMG: OR = 4,03; IC95%: 3,53-4,60), percepção sobre a qualidade do ambiente urbano como ruim (IAL: OR = 1,57; IC95%: 1,36-1,81/IAMG: OR = 2,03; IC95%: 1,73-2,38), com maior prevalência de insegurança alimentar em cenários de pior situação sociodemográfica. Na macrozona Miolo todos os fatores também se mantiveram associados à insegurança alimentar. Assim, os fatores de vulnerabilidade social estão associados à insegurança alimentar na capital e macrozonas, mas apresentam-se de formas especificas segundo características de cada território.

This study aimed to present the prevalence of household food insecurity in different territories of the city of Salvador, Bahia State, Brazil, and to analyze demographic and socio-environmental factors associated with it. The data used are from a larger survey named Quality of the Urban Environment of Salvador - QUALISalvador, carried out from 2018 to 2020 in in the city. Food insecurity was assessed using the Brazilian Food Insecurity Scale. A total of 15,171 households were analyzed. Multinomial logistic regression models were used to analyze the association of demographic and socio-environmental variables with mild food insecurity (MFI) and moderate or severe food insecurity (MSFI) for Salvador and by macrozones. Salvador presented 40.96% of food insecurity. In the macrozones, the prevalence differed: Atlantic Coast (25.8%), Consolidated Urban Area (33%), Suburb (45.7%), and Core (47.9%). All factors analyzed were associated with MFI and/or MSFI in the model for Salvador, namely: household head having schooling ≤ 4 years (MFI: OR = 2.00; 95%CI: 1.61-2.47/MSFI: OR = 4.94; 95%CI: 3.83-6.35), having per capita family income of up to 1/2 minimum wage (MFI: OR = 2.62; 95%CI: 2.37-2.93/MSFI: OR = 4.03; 95%CI: 3.53-4.60), perception of the quality of the urban environment as poor (MFI: OR = 1.57; 95%CI: 1.36-1.81/MSFI: OR = 2.03; 95%CI: 1.73-2.38), with a higher prevalence of food insecurity in scenarios of worse sociodemographic situation. In the Core Macrozone, all factors were also associated with food insecurity. Thus, the factors of social vulnerability are associated with food insecurity in the capital and macrozones, but they are presented in a specific way according to the characteristics of each territory.

Resumen: Esta investigación tiene como objetivo analizar la industria manufacturera de la frontera norte de México para identificar las tendencias de su desarrollo en el periodo de 1999 a 2019. Se plantea la hipótesis de que su desempeño ha sido de alta especialización, lo que hace difícil la presencia de desindustrialización como patrón de cambio estructural. Para alcanzar el objetivo y contrastar la hipótesis se calcularon un índice de cambio estructural, un coeficiente de especialización, y un modelo con datos panel para analizar los determinantes del coeficiente de especialización. Los resultados sugieren que no existe un proceso de desindustrialización en la frontera norte, por la alta especialización en la manufactura, que se explica por variables que favorecen a la manufactura como el PIB de Estados Unidos, el tipo de cambio real, la inversión y la población ocupada.

Abstract: This research aims to analyze the manufacturing industry of the northern border of Mexico to identify its development trends in the period of 1999 to 2019. It is hypothesized that its performance has been of high specialization, which makes the presence of deindustrialization as a pattern of structural change difficult. To reach the objective and test the hypothesis, a structural change index, a specialization coefficient and a model with panel data was calculated to analyze the determinants of the specialization coefficient. The results suggest that there is no process of deindustrialization on the northern border, due to the high specialization in manufacturing that is explained by variables that favor manufacturing such as the GDP of the United States, the real exchange rate, investment and the employed population.

Abstract This study aimed to evaluate the air and water contamination level and to identify the microbes isolated from a rodent facility located at the Federal University of Uberlândia, Minas Gerais, Brazil. Colony forming units (CFU) per milliliter was used for monitoring water quantitatively; CFU per cubic meter was used for air monitoring. The isolated colonies were identified for qualitative monitoring. Due to absence of specific parameters for these facilities, the results were analyzed according to Brazilian and international standards, depending on which best suited each sample. The mean total number of microorganisms in water ranged from 0.015 ± 0.02 to 0.999 ± 0.91 CFU/mL. The number of microorganisms in air ranged from 9.1 ± 4.6 to 351.56 ± 158.2 CFU/m³. Forty-one microorganisms identified in the samples obtained from the rodent facility were potentially pathogenic or opportunistic for animals and humans (e.g., Corynebacterium spp.). We concluded that the water and air samples were contaminated with potentially pathogenic or opportunistic microorganisms that can harm rodents and humans. On the basis of our observations, specific sanitary standards suitable for these facilities should be developed for controlling microbial contamination, which will prevent zoonosis and ensure the reliability of scientific results obtained from animal experiments.

Metodología: estudio de corte transversal con análisis de prueba diagnóstica en pacientes mayores de 18 años con sospecha diagnóstica de embolia pulmonar al ingreso o durante la hospitalización llevado a toma de angiotomografía de tórax desde agosto de 2009 hasta enero de 2020 en un centro de tercer nivel ubicado en la Sabana de Bogotá, se evaluó el rendimiento del puntaje PERC (Embolism Rule-Out Criteria) calculado con una SatO2<95% y una SatO2<90% en pacientes con diferentes niveles de riesgo según los puntajes de Wells, Ginebra y Pisa para embolia pulmonar. Resultados: mil ochenta y siete ingresaron al análisis final, 42% con EP Se encontró para los pacientes clasificados de bajo riesgo por el puntaje de Wells un ACOR para el PERC calculado con SatO2<95% de 0.56 (IC-95%:0.50-0.62) (p=0.049), y para el PERC calculado con SatO2<90% de 0.60 (IC-95%:0.54-0.66) (p=0.002), el ACOR para sujetos clasificados de bajo riesgo por el puntaje de Ginebra con un PERC calculado con SatO2<95% fue de: 0.53 (IC-95%:0.45-0.60) (p=0.459) y para un PERC calculado con SatO2<90% fue de: 0.55 (IC-95%:0.47-0.62) (P=0.218), el ACOR para sujetos clasificados con menos de 10% de probabilidad para EP por el puntaje de Pisa con un PERC calculado con SatO2<95% fue de: 0.54 (IC-95%:0.44-0.64)(p=0.422) y para un PERC calculado con SatO2<90% fue de: 0.56 (IC-95%:0.46-0.66)(p=0.236). Conclusiones: el puntaje PERC calculado con una saturación de oxígeno <90% tiene un rendimiento diagnóstico similar al puntaje PERC calculado con una saturación de oxígeno <95% para descartar EP en pacientes clasificados en bajo riesgo con puntaje de Wells a gran altitud (>2500 msnm).

Abstract Objectives: to validate the diagnostic yield of the PERC score for ruling out pulmonary embolism in low-risk patients at high altitudes (>2500 meters above sea level [ASL]). Methods: a cross-sectional study with diagnostic test analysis in patients over the age of 18 with suspected pulmonary embolism on admission or during hospitalization, who underwent chest computed tomography angiography between August 2009 and January 2020 in a tertiary care hospital located on the Bogotá savannah. The yield of the PERC score was assessed, calculated with an SaO2<95% and an SaO2<90% in patients with different risk levels according to the Wells, Geneva and Pisa scores for pulmonary embolism. Results: one thousand eighty-seven were included in the final analysis, 42% with PE. Patients classified as low-risk using the Wells score had a PERC ACOR calculated with SaO2<95% of 0.56 (95%CI:0.50-0.62) (p=0.049), and calculated with SaO2<90% of 0.60 (95%CI:0.54-0.66) (p=0.002). The ACOR for subjects classified as low-risk using the Geneva score, with a PERC calculated with SaO2<95%, was: 0.53 (95%CI:0.45-0.60) (p=0.459) and for a PERC calculated with SaO2<90% it was: 0.55 (95%CI:0.47-0.62) (P=0.218). The ACOR for subjects with a less than 10% probability of PE according to the Pisa score classification, with a PERC calculated with SaO2<95%, was: 0.54 (95%CI:0.44-0.64)(p=0.422), and for a PERC calculated with SaO2<90% it was: 0.56 (95%CI:0.46-0.66)(p=0.236). Conclusions: the PERC score calculated with an oxygen saturation <90% has a similar diagnostic yield to the PERC score calculated with an oxygen saturation <95% for ruling out PE in patients classified as low-risk by the Wells score at high altitudes (>2,500 meters ASL).

SUMMARY OBJECTIVE: The aim of this study was to build a prediction model to discriminate precociously hantavirus infection from leptospirosis, identifying the conditions and risk factors associated with these diseases. METHODS: A logistic regression model in which the response variable was the presence of hantavirus or leptospirosis was adjusted. RESULTS: As a result, the method selected the following variables that influenced the prediction formula: sociodemographic variables, clinical manifestations, and exposure to environmental risks. All variables considered in the model presented statistical significance with a p<0.05 value. The accuracy of the model to differentiate hantavirus from leptospirosis was 88.7%. CONCLUSIONS: Concluding that the development of statistical tools with high potential to predict the disease, and thus differentiate them precociously, can reduce hospital costs, speed up the patient’s care, reduce morbidity and mortality, and assist health professionals and public managers in decision-making.

RESUMEN Introducción: El uso de medicina complementaria y alternativa (MCA) en pacientes con enfermedades reumáticas es prevalente pero la comunicación con el reumatólogo suele ser deficiente, lo cual afecta la relación médico-paciente (RMP). Objetivos: Evaluar la asociación entre el uso de MCA y la RMP en enfermos con artritis reumatoide. Como objetivos adicionales, describir la percepción del paciente sobre la comunicación con su reumatólogo respecto al uso de MCA y el patrón de uso de las diferentes modalidades terapéuticas. Materiales y métodos: Estudio descriptivo de corte transversal. El uso de MCA y la RMP se evaluaron mediante la autoaplicación de cuestionarios validados (I-CAM-Q y PDRQ-9 respectivamente). Resultados: Se incluyó a 246 pacientes ambulatorios de una institución de tercer nivel de atención. Se encontró asociación entre una mayor satisfacción con el tratamiento y el no usar MCA, y entre el hecho de informar al reumatólogo sobre el uso de MCA con un mayor grado de acuerdo con el médico sobre el origen de los síntomas y mayor satisfacción con el tratamiento. Las modalidades más frecuentemente utilizadas fueron: quiropraxia, acupuntura y productos herbales. El 78,5% afirmaron estar de acuerdo con comunicar el uso de este tipo de medicación al reumatólogo, sin embargo, solo el 31,3% lo notificó, por temor a represalias (54,4%). Conclusiones: Pese a la alta prevalencia de uso de MCA en nuestros pacientes, la mayoría no lo comunicó al reumatólogo. Se encontró asociación entre el uso de MCA y una menor satisfacción del paciente con el tratamiento y entre la comunicación médico-paciente sobre la práctica de MCA y una mejor satisfacción con el tratamiento.

ABSTRACT Introduction: Although complementary and alternative medicine (CAM) use among patients with rheumatic diseases is extensive, discussions regarding these treatments occur rarely in the rheumatology setting, directly affecting the physician-patient relationship (PPR). Objectives: The aim of this study was to evaluate the association between patient-physician relationship and complementary and alternative medicine use. As secondary objectives, to describe the patient's perspective towards CAM use and estimate the prevalence of CAM treatments used in patients with rheumatoid arthritis. Methods and materials: A descriptive cross-sectional survey was conducted, in which CAM use and physician-patient relationship were assessed by self-reported validated questionnaires (I-CAM-Q and PDRQ-9, respectively). Results: The study included a total of 246 outpatients of a tertiary care hospital. There were no significant differences between CAM users vs. non-users, or informers vs. non-informers in terms of physician-patient relationship measured by PDQR. The most frequent used CAM treatments were: chiropractice, acupuncture, and herbal products. A large majority (78.5%) of the patients expressed agreement to the discussion of CAM use with the rheumatologist, but only 31.3% of total CAM users did so because of fear of retaliation (54.4%). Conclusion: Despite the extensive practice of CAM among patients with rheumatoid arthritis, most patients did not discuss these treatments with their physicians. Associations were found between MCA use and a lower patient's treatment satisfaction and between physician-patient communication about CAM practice and a higher patient's treatment satisfaction.

Resumen Introducción: El valor de las colecciones científicas radica en que los registros están vinculados directamente a especímenes físicos permitiendo conocer los avances en taxonomía, biogeografía e historia evolutiva de las especies. En El Salvador, las colecciones científicas están representadas en su mayoría por ejemplares de vertebrados terrestres y en menor proporción invertebrados marinos, en específico para el grupo de equinodermos su representación es escasa. Objetivo: Enlistar las colecciones científicas en las cuales se encuentran depositados ejemplares de equinodermos de El Salvador, conocer los esfuerzos realizados para la recolección de estos ejemplares y evaluar el aporte de las colecciones al conocimiento del taxón en el país. Métodos: Revisión de bases de datos abiertas de 18 colecciones extranjeras y nacionales; recopilando información biológica, número de ejemplares, sitio, año de recolecta y recolector. Resultados: Se encontraron 536 ejemplares en 192 registros de equinodermos depositados en seis colecciones científicas, nacionales y extranjeras, clasificadas en 40 especies, una de ellas nueva para El Salvador: Ophionereis perplexa. El National Museum of Natural History Smithsonian y el Instituto de Ciencias del Mar y Limnología de la Universidad de El Salvador albergan el mayor número de ejemplares, el primero con los ejemplares más antiguos, con más recolectas en La Unión y Sonsonate para ambas colecciones. Conclusiones: La representación de ejemplares en colecciones científicas nacionales y extranjeras es aceptable, registrando en los depósitos el 66.7 % del total reportado para El Salvador. Se recomienda continuar los esfuerzos en la identificación y catalogación de especies de aguas someras e iniciar las investigaciones con el taxón en aguas profundas.

Abstract Introduction: The value of scientific collections lies in the fact that the records are directly linked to real physical specimens allowing us to learn the advances in taxonomy, biogeography and evolutionary history of the species. In El Salvador, the scientific collections are represented mostly by specimens of terrestrial vertebrates and, to a lesser proportion, marine invertebrates, specifically for the group of echinoderms their representation is scarce. Objective: To enlist the scientific collections in which echinoderm specimens of El Salvador are deposited, to know about the efforts made to collect these specimens and evaluate the contribution of the collections to the knowledge of the taxon in the country. Methods: Review of open databases of 18 foreign and national collections; collecting biological information, number of specimens, site, year of collection and collector. Results: 536 specimens were found in 192 records of echinoderms deposited in six scientific collections, national and foreign, classified into 40 species, one of them new for El Salvador: Ophionereis perplexa. The National Museum of Natural History (Smithsonian) and the Institute of Marine Sciences and Limnology of the University of El Salvador have the largest number of specimens (Smithsonian has the oldest specimens). Conclusions: The representation of specimens in national and foreign scientific collections is acceptable, with 67 % of the total reported for El Salvador. We recommend continuation of work in shallow-waters and start of deep-water study.
