ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Background: Variability in snake venoms is a well-studied phenomenon. However, sex-based variation of Bothrops atrox snake venom using siblings is poorly investigated. Bothrops atrox is responsible for the majority of snakebite accidents in the Brazilian Amazon region. Differences in the venom composition of Bothrops genus have been linked to several factors such as ontogeny, geographical distribution, prey preferences and sex. Thus, in the current study, venom samples of Bothrops atrox male and female siblings were analyzed in order to compare their biochemical and biological characteristics. Methods: Venoms were collected from five females and four males born from a snake captured from the wild in São Bento (Maranhão, Brazil), and kept in the Laboratory of Herpetology of Butantan Intitute. The venoms were analyzed individually and as a pool of each gender. The assays consisted in protein quantification, 1-DE, mass spectrometry, proteolytic, phospholipase A2, L-amino acid oxidase activities, minimum coagulant dose upon plasma, minimum hemorrhagic dose and lethal dose 50%. Results: Electrophoretic profiles of male’s and female’s venom pools were quite similar, with minor sex-based variation. Male venom showed higher LAAO, PLA2 and hemorrhagic activities, while female venom showed higher coagulant activity. On the other hand, the proteolytic activities did not show statistical differences between pools, although some individual variations were observed. Meanwhile, proteomic profile revealed 112 different protein compounds; of which 105 were common proteins of female’s and male’s venom pools and seven were unique to females. Despite individual variations, lethality of both pools showed similar values. Conclusion: Although differences between female and male venoms were observed, our results show that individual variations are significant even between siblings, highlighting that biological activities of venoms and its composition are influenced by other factors beyond gender.

Resumen Se evaluó la dinámica oceanográfica relacionada con los procesos de alta productividad en el Caribe norte colombiano. Se realizaron cuatro cruceros científicos entre mayo y diciembre de 2018, en los que se midieron la temperatura, la salinidad y el oxígeno con una sonda CTDO y transparencia con un disco Secchi. Mayo y diciembre presentaron aguas típicas de afloramientos con menor intensidad, mientras que agosto y noviembre tuvieron aguas características de la época lluviosa. La dinámica espacial estuvo relacionada con la temperatura y la salinidad. Las estaciones del noreste presentaron aguas superficiales más frías y salinas, en relación con las localizadas hacia el suroeste. A nivel vertical, se identificó la masa de agua superficial del Caribe, y debajo la masa de agua subsuperficial subtropical que aflora a inicios de año. Los resultados sugieren que la surgencia y los aportes de agua dulce tienen un impacto directo sobre la estructura hidrográfica de la región.
Abstract This study explored oceanographic dynamics related to high productivity processes in the northern Colombian Caribbean. Four scientific expeditions were carried out between May and December 2018, where selected physicochemical variables were measured using a CTDO (conductivity, temperature and dissolved oxygen sensor system), and transparency with a Secchi disc. May and December showed typical upwelling waters, while August and November showed waters characteristic of the rainy season. Spatial dynamics were related to temperature and salinity. Thus, northeastern stations showed colder and saltier surface waters compared to those located to the southwest. Vertical readings were taken and the Caribbean Surface Water mass was identified, and below it the subtropical subsurface water mass, which emerges at the beginning of the year. The results suggest that upwelling and freshwater runoff have a direct impact on the hydrographic structure of the region.

RESUMO: Esta pesquisa teve como objetivo detectar diretamente em amostras de leite contaminado artificialmente Staphylococcus coagulase positiva (ECP) por multiplex PCR (mPCR). Cepas padrão e isolados de S. aureus, S. epidermidis, S. hyicus, S. intermedius, Listeria monocytogenes e Escherichia coli foram utilizados no estudo. Foram utilizados primers específicos para o gene nuc (NUC1-NUC2 para o S. aureus, NUC3-NUC4 para o S. hyicus e NUC5-NUC6 para o S. intermedius ). Foi possível detectar as três espécies-alvo por mPCR, formar diretamente nas amostras de leite integral bovino, com especificidade adequada e limite de detecção aceitável para identificação de espécies de Staphylococcus coagulase positiva (ECP) em alimentos. A especificidade foi determinada por meio da amplificação de fragmentos específicos das espécies e o limite de detecção foi avaliado pelos limiares de detecção obtidos para as três espécies (103 UFC mL-1 para as espécies presentes nas amostras de leite contaminadas artificialmente).
ABSTRACT: This research aimed to detect coagulase-positive Staphylococcus (CPS) directly in samples of artificially contaminated milk, using multiplex PCR (mPCR). Standard and isolated bacterial strains of S. aureus, S. epidermidis, S. hyicus, S. intermedius, Listeria monocytogenes and Escherichia coli species were used, evaluating the specificity and detection limit of mPCR, for artificially contaminated UHT milk. Primers specific for the nuc gene (NUC1-NUC2 were used for S. aureus, NUC3-NUC4 for S. hyicus and NUC5-NUC6 for S. intermedius). It was possible to detect the three target species by mPCR, directly from bovine whole milk, with adequate specificity and acceptable detention limit for identification of coagulase-positive Staphylococcus (CPS) in foods. The specificity was determined by the amplification of species-specific fragments, and the detection limit was assessed by the detection thresholds obtained for the three species (103 CFU mL-1). From these results, the mPCR described, with the proposed set of primers, has the potential for use in precise identification and differentiation between CPSs in milk samples.

In the Brazilian Amazon, American tegumentary leishmaniasis (ATL) is endemic and presents a wide spectrum of clinical manifestations due, in part, to the circulation of at least seven Leishmaniaspecies. Few reports of Leishmania (Viannia) naiffiinfection suggest that its occurrence is uncommon and the reported cases present a benign clinical course and a good response to treatment. This study aimed to strengthen the clinical and epidemiological importance of L. (V.) naiffiin the Amazon Region (Manaus, state of Amazonas) and to report therapeutic failure in patients infected with this species. Thirty Leishmania spp samples isolated from cutaneous lesions were characterised by multilocus enzyme electrophoresis. As expected, the most common species was Leishmania (V.) guyanensis (20 cases). However, a relevant number ofL. (V.) naiffi patients (8 cases) was observed, thus demonstrating that this species is not uncommon in the region. No patient infected withL. (V.) naiffievolved to spontaneous cure until the start of treatment, which indicated that this species may not have a self-limiting nature. In addition, two of the patients experienced a poor response to antimonial or pentamidine therapy. Thus, either ATL cases due to L. (V.) naifficannot be as uncommon as previously thought or this species is currently expanding in this region.

La corrupción es un fenómeno universal, pero muchas sociedades han contrarrestado sus efectos negativos mediante políticas públicas y esfuerzos sociales que promueven la transparencia y los valores sociales. Este artículo examina los arreglos microinstitucionales de las zonas mineras de Antioquia, Bolívar y Córdoba, y su relación con la corrupción. Los resultados sugieren que las reglas formales e informales y los atributos de estas comunidades desalientan la confianza entre sus miembros e incentivan las prácticas corruptas.
Corruption is a universal phenomenon. However, many societies have managed to counteract its negative effects through public policies and sustained social efforts on transparency and prosocial values. This article seeks to examine the micro-institutional arrangements of the mining areas of the departments of Antioquia, Córdoba and Bolívar, and their relationship to corruption. The results of the fieldwork suggest that the formal and informal rules and community attributes of the mining regions under study encourage corrupt practices, particularly through the loss of trust among their people.

Extracorporeal membrane oxygenation is considered a rescue therapy and complex vital support with benefits in cardiorespiratory diseases during neonatal period that fulfil the characteristics of being reversible in neonates older than 34 weeks. The criteria for patient selection and its prompt use are critical for the final result. Even though new alternatives for management of hypoxemic respiratory failure in full term and almost full term neonates have decreased its use, congenital diaphragmatic hernia continues being a complex disease where it can have some applicability. Even though our experience is beginning, constant training will make of extracorporeal membrane oxygenation an option for complex patients in whom maximum therapy fails. This is a report of the first neonatal cases of hypoxemic respiratory failure managed at Fundación Cardiovascular de Colombia.
La oxigenación de membrana extracorpórea se considera una terapia de rescate y soporte vital compleja, con beneficios en enfermedades cardiorrespiratorias durante el periodo neonatal, que cumple con las características de ser reversible en recién nacidos mayores de 34 semanas. El criterio de selección de los pacientes y el momento oportuno en que se indica son críticos para el resultado final, si bien las nuevas alternativas de manejo en falla respiratoria hipoxémica en recién nacidos a término y casi a término han generado una disminución de su uso, excepto en la hernia diafragmática, que continúa siendo una enfermedad compleja donde podría tener alguna aplicabilidad. Si bien nuestra experiencia está iniciándose, el entrenamiento constante hará de la oxigenación de membrana extracorpórea una opción para pacientes complejos en quienes la terapia máxima fracasa. Se hace un informe de los primeros casos neonatales por falla respiratoria hipoxémica manejados en la Fundación Cardiovascular de Colombia.

Objective: The aim of this study was to design and validate a questionnaire to measure perceived symptoms associated with antihypertensive drugs (PERSYVE). Methods: The PERSYVE development and validation included four stages: 1) item development (bibliographic review and questionnaire elaboration); 2) face and content validation; 3) field testing (pre-test); and 4) test-retest validation, assessment of internal consistency (Cronbach´s alpha) and reproducibility over time (intraclass correlation coefficient and Cohen´s kappa coefficient). Results: PERSYVE is divided into six sections according to results obtained from the literature review: (1) drug adherence, (2) perceived symptoms and how they affect quality of life (five-point Likert scale), (3) communication with health professionals, (4) perception of symptoms as adverse reactions, (5) influence on therapy compliance, and (6) adoption of non-pharmacological methods for blood pressure control. Content and face validation of the questionnaire led to some vocabulary changes and the introduction of section 2.1. Field-testing (n=26) revealed high comprehensibility of the questions. The Cronbach's alpha, calculated for section 2 (five-point Likert scale) was 0.850. PERSYVE was reproducible (n=167): kappa values presented fair to substantial reproducibility and, in section 2, ICC values resulted in good to excellent reproducibility. Conclusion: Results showed that PERSYVE is a well-structured, objective, patient-friendly, valid and reliable questionnaire. PERSYVE can be a very useful instrument in hypertensive patients´ monitoring and in the screening of adverse effects.
Objetivo: El objetivo de este estudio fue diseñar y validar un cuestionario para medir los síntomas percibidos asicados a medicamentos antihipertensivos (PERSYVE). Métodos: El desarrollo y validación de PERSYVE incluyó cuatro etapas: 1) desarrollo de ítems (revisión bibliográfica y elaboración del cuestionario); 2) validación de rostro y de contenido; 3) prueba de campo (pre-test); y 4) validación test-retest, evaluación de la consistencia interna (alfa de Chronbach) y reproductibilidad en el tiempo (coeficiente de correlación intra-clases y coeficiente kappa de Cohen). Resultados: De acuerdo con los resultados obtenidos de la revisión de la literatura, PERSYVE se divide en seis secciones: (1) adherencia a medicamentos, (2) síntomas percibidos y como afectan a la calidad de vida (escala Likert de cinco puntos), (3) comunicación con los profesionales de la salud, (4) percepción de síntomas como reacciones adversas, (5) influencia en el cumplimiento del tratamiento, y (6) adopción de métodos no farmacológicos para el control de la presión arterial. La validación de rostro y de contenido del cuestionario llevaron a algunos cambios de vocabulario y a la introducción de la sección 2.1. El ensayo de campo (n=26) reveló una alta comprensibilidad de las preguntas. El alfa de Cronbach calculado para la sección 2 (escala de Likert de 5 puntos) fue de 0,850. PERSYVE fue reproducible (n=167): valores de kappa presentaron una reproductibilidad sustancial y, en la sección 2, los valores de ICC resultaron de buenos a excelentes. Conclusión: Los resultados demostraron que PERSYVE es un cuestionario bien estructurado, objetivo, fácil de usar para el paciente, válido y confiable. PERSYVE puede ser un instrumento muy útil en la monitorización de pacientes hipertensos y en el rastreo de efectos adversos.

Este artigo analisa as relações entre cosmopolitismo e particularismos na abordagem da temática do exílio presente nas trajetórias, obras e discursos de escritores (Adolfo Casais Monteiro, Jorge de Sena e Vitor Ramos) e cientistas (António Aniceto Monteiro, António Brotas, Alfredo Pereira Gomes, José Morgado e Ruy Luis Gomes) portugueses radicados no Brasil entre 1945 e 1974. A circulação internacional de cientistas e escritores portugueses, exilados durante a vigência do Estado Novo em Portugal, contou com o apoio de redes profissionais, de amizade, de parentesco ou de filiação ideológica no campo da oposição, mas foi também resultado de formas de expulsão do país de origem e de impedimentos à atuação, tanto em Portugal quanto no estrangeiro. Neste sentido, este texto também foca as trajetórias pessoais e coletivas dos personagens e como estas teriam relação com as fronteiras de pertencimento que estabeleceram ao longo da vida.
This article analyses the relationship and tensions between cosmopolitanism and particularism in the way in which the subject of exile is broached in the life stories, works and ideas of the Portuguese writers Adolfo Casais Monteiro, Jorge de Sena and Vitor Ramos, and scientists Antonio Aniceto Monteiro, Antonio Brotas, Alfredo Pereira Gomes, José Morgado and Ruy Luis Gomes, who lived in Brazil between 1945 and 1974. The careers and experiences of these individuals were characterised by a way of relating to the world marked by continuous exclusion from the centres of hegemonic power, as well as by the establishment of connections and networks of varying degrees. In this sense, this article also focuses on the personal and collective trajectories of the characters and how it is related to the boundaries of belonging that they established during their lives.

Na busca pela identificação de novas fontes de antioxidantes naturais e de esclarecer lacunas acerca das reais propriedades benéficas atribuídas ao Noni (Morinda citrifolia Linn), este trabalho teve como objetivo realizar a caracterização química e avaliar a atividade antioxidante da polpa, casca e sementes do noni. Foram determinadas a composição centesimal (umidade, cinzas, proteínas, carboidratos e lipídios); os compostos bioativos (fenólicos totais, carotenoides totais e vitamina C) e a atividade in vitro em extratos aquoso, etanólico e acetônico. Os resultados demonstraram que o Noni possui quantidades significativas de carboidratos (27,21%; 9,70% e 8,37%) e de proteínas (2,64%; 2,23%; e 2,24%) nas sementes, casca e polpa, respectivamente. A polpa apresentou maior teor de vitamina C (23,1 mg/100g) e de carotenoides totais (3,90 mg/100g). No extrato acetônico da polpa, foram quantificados 109,81 mg/100g de fenólicos totais, seguidos pelos extratos acetônicos da casca (76,01 mg/100g), das sementes (28,75 mg/100g) e do extrato etanólico da polpa (20,33 mg/100g). Todos os extratos avaliados apresentaram atividade antioxidante in vitro; os extratos acetônico e etanólico da casca e das sementes do Noni apresentaram maior atividade pelo método β-caroteno/ ácido linoleico, enquanto o extrato etanólico da polpa teve maior atividade antioxidante pelo ensaio DPPH e ABTS, e o extrato acetônico da polpa, pelo método ABTS. O noni é um fruto com significativo teor de compostos fenólicos totais que apresentam atividade antioxidante in vitro.
In an attempt to identify new sources of natural antioxidants and to clarify gaps in the scientific literature about the real beneficial properties attributed to Noni (Morinda citrifolia Linn), this study aimed to determine the chemical characterization and to evaluate antioxidant activity of the pulp, skin and seeds of Noni. Chemical composition (moisture, ash, protein, carbohydrates and lipids), bioactive compounds (total phenolics, total carotenoids and vitamin C), and the in vitro activity in aqueous, ethanolic and acetone extracts were determined. The results showed that compared to others fruits, the different parts of Noni have significant amounts of carbohydrates (27.21%, 9.70% and 8.37%) and protein (2.64%, 2.23 %, and 2.24 %) in seeds, skin and pulp, respectively. The pulp had a higher content of vitamin C (23.1 mg/100 g) and carotenoids (3.90 mg/100g).An amount of 109.81 mg/100 g of total phenolics was determined in the acetone extract of the pulp, followed by 76.01 and 28.75 mg/100g in the acetonic extracts of the skin and seeds, respectively and the ethanolic extract of the pulp with 20.33 mg/100g). All extracts showed antioxidant activity in vitro. The acetone and ethanolic extracts of the skin and seeds of Noni showed higher activity by the β-carotene / linoleic acid method while the ethanolic pulp extract had a higher antioxidant activity by DPPH and ABTS assay and the acetone extract of the pulp by the ABTS method. Data showed that Noni has high content of phenolic compounds with antioxidant capacity in vitro in different parts of the fruit.

OBJECTIVE: To determine if there is a correlation between socioeconomic conditions and in-hospital mortality (IHM) from ischemic stroke in a sample of the Colombian population and identify the chain of events that determine that association. METHODS: Prospective study of a hospital cohort of patients with ischemic stroke in four Colombian clinical referral institutions-located in Floridablanca, Bucaramanga, Bogotá, and Medellín-between February 2003 and December 2006. Hierarchical analysis was used to group the socioeconomic variables into three levels, and their relationship to IHM due to ischemic stroke was assessed in a Cox proportional hazards model. RESULTS: The IHM rate was 9.4% in the 253 patients included in the study. In the analysis by levels, mortality was inversely associated with educational level (advanced to primary), monthly income (≥ minimum wage), and participation in the contributory health system. When the three levels were combined in the hierarchical analysis, affiliation with the contributory system was the only association that maintained its statistical significance (RR 0.35; CI 95%: 0.13-0.96; P = 0.04). CONCLUSIONS: The results indicate that, in Colombia, being affiliated with the contributory health system is an independent protective factor against IHM after an ischemic stroke. The education-income-access to health services sequence is a possible explanation for the relationship between socioeconomic conditions and the clinical outcome of these events. Strategies should be designed to mitigate the differences in the quality and distribution of health services in the Colombian population.
OBJETIVO: Determinar si existe asociación entre las condiciones socioeconómicas y la mortalidad intrahospitalaria (MIH) por accidente cerebrovascular (ACV) isquémico en una muestra de población colombiana e identificar la cadena de eventos que determinan esa asociación. MÉTODOS: Estudio prospectivo de una cohorte hospitalaria de pacientes con ACV isquémico registrados en cuatro instituciones clínicas de referencia colombianas -ubicadas en Floridablanca, Bucaramanga, Bogotá y Medellín- entre febrero de 2003 y diciembre de 2006. Mediante análisis jerárquico se evaluaron las variables socioeconómicas agrupadas en tres niveles para determinar su relación con la MIH por ACV isquémico en un modelo de riesgos proporcionales de Cox. RESULTADOS: En los 253 pacientes incluidos, la MIH fue de 9,4 %. En el análisis por niveles, la mortalidad estuvo inversamente asociada con el nivel educacional (estudios superiores a primaria), los ingresos mensuales (≥ salario mínimo) y la vinculación al régimen contributivo. En el análisis jerárquico, al combinar los 3 niveles, solo la asociación inversa con la afiliación al régimen contributivo mantuvo su significación estadística (RR 0,35; IC95%: 0,13-0,96; P = 0,04). CONCLUSIONES: Los resultados indican que en Colombia, el estar afilado al régimen contributivo de salud es un factor protector independiente contra la MIH tras un ACV isquémico. La secuencia educación-ingresos-acceso a servicios de salud constituye una vía de explicación de la relación entre las condiciones socioeconómicas y el desenlace clínico de estos eventos. Se deben diseñar estrategias para mitigar las diferencias en la calidad y la distribución de los servicios de salud en la población colombiana.

RESUMEN Introducción. El sobrepeso y la obesidad han sido postulados como factores de riesgo para enfermedad coronaria, sin embargo, los estudios epidemiológicos han mostrado resultados contradictorios acerca de la asociación de estos factores con el riesgo de desarrollar enfermedad cerebrovascular isquémica aguda (ECV). Materiales y métodos. La presente investigación es un subanálisis del análisis nacional multicéntrico de casos y controles para el estudio Factores de riesgo de enfermedad cerebrovascular isquémica en Colombia (FREC-VI). Se incluyó una muestra de 253 pacientes con diagnóstico confirmado de ECV y 253 controles. Se propuso como objetivo evaluar la asociación entre la obesidad y el sobrepeso con el riesgo de desarrollar ECV isquémica aguda ajustando por la presencia de posibles factores confusores, mediante la aplicación de una regresión logística múltiple. Resultados. Los casos presentaron una media menor de IMC (24,90 ± 3,77 kg/m2 vs. 25,87 ± 4,25 kg/m2; p = 0,0091), además de una menor proporción de obesidad (7,51% vs. 15,05%; p = 0,010) en comparación con los controles. En el análisis crudo la obesidad mostró tendencia hacia la asociación como factor protector, no obstante, al realizar el ajuste mediante el análisis multivariado tanto el sobrepeso como la obesidad no mostraron significancia. Conclusiones. La presencia de sobrepeso u obesidad no mostró asociación con el hallazgo de ECV isquémica aguda en una muestra de población colombiana.
SUMMARY Introduction. Overweight and obesity have been postulated as risk factors for coronary arterial disease, however epidemiological studies have shown conflicting results about the association of these factors with the risk of developing cerebrovascular disease. Materials and methods. The present study is a sub-analysis of the national multicenter Case-Control Study of Risk Factors for ischemic stroke in Colombia "FREC-VI". A sample of 253 patients with confirmed diagnosis of ischemic stroke and 253 controls was included. The study aim was to assess the association between obesity and overweight with the risk of developing ischemic stroke adjusting for possible confounding factors. Results. Cases had a lower BMI (24.90 ± 3.77 kg/m2 vs 25.87 ± 4.25 kg/m2; p = 0.0091), and a lower proportion of obesity (7.51% vs 15.05%; p = 0.01) compared with controls. The crude analysis showed a tendency of obesity as a protective factor, however, after adjustment by other covariates, both overweight and obesity lost their significance. Conclusion. Overweight and obesity are not associated with acute ischemic stroke in Colombian population.
