Resumen Antecedentes: En los pseudoaneurismas infectados de arteria femoral asociados al uso de drogas intravenosas, la ligadura primaria para el tratamiento causa controversia, sin embargo, el territorio comprometido puede continuar irrigado por vías colaterales. Objetivo: Reportar la experiencia del manejo de pseudoaneurismas en un servicio de angiología y cirugía vascular. Métodos: Estudio observacional, descriptivo de una serie de casos. Resultados: Se reportan 15 pacientes, relación hombre: mujer 14:1, promedio de edad de 42 años. Siete (46.6%) con presentación de pseudoaneurisma femoral izquierdo, 5 (33.3%) de ellos con presentación de pseudoaneurisma femoral derecho, 2 (13.3%) con pseudoaneurisma humeral derecho y uno (6.6%) con pseudoaneurisma humeral izquierdo. En 12 se realizó exclusión del pseudoaneurisma con triple ligadura; y 3 pacientes fueron sometidos a revascularización. Conclusiones: En nuestra experiencia, la ligadura primaria sin revascularización tuvo incidencia de amputación baja y supervivencia alta de los pacientes afectados, siendo la claudicación la secuela más frecuente.

Abstract Background: In intravenous drug-infected femoral pseudoaneurysms, primary ligation for treatment is controversial, but the compromised territory can remain irrigated by collateral routes. Objective: To report the experience in the management of pseudoaneurysms in our angiology and vascular surgery service. Methods: Observational, descriptive study of a series of cases. Results: 15 patients are reported, male: female ratio 14:1, average age 42 years. Seven (46.6%) presented with a left femoral pseudoaneurysm, 5 (33.3%) presented with a right femoral pseudoaneurysm, 2 (13.3%) with a right brachial pseudoaneurysm, and one (6.6%) with a left brachial pseudoaneurysm. In 12, exclusion of the pseudoaneurysm was performed with triple ligation; 3 patients underwent revascularization. Conclusions: In our experience the primary ligature without revascularization has a low incidence of amputation and high survival of affected patients, being claudication the most frequent sequel.

Resumen Los enfoques actuales de los Planes de Estudio de la Educación Media Superior y Superior en México demandan desarrollar conocimientos interdisciplinarios que exigen una articulación de saberes provenientes de distintas disciplinas a fin de abordar problemas complejos. Ante estas demandas, los docentes enfrentan desafíos para, entre otros asuntos, diseñar e implementar estrategias de enseñanza que atiendan el trabajo interdisciplinar en sus aulas. En este artículo reportamos avances de una investigación más amplia que estudia el uso de proyectos estadísticos como un recurso para fomentar una competencia interdisciplinar. Basados en la revisión de literatura, definimos cuatro características de esa competencia: comprensión disciplinar, integración disciplinar, reflexividad, y, producción e intercambio de objetos limitáneos. El objetivo del artículo es explorar el desarrollo de esas características por parte de formadores de docentes de diferentes áreas disciplinares durante la planificación de un proyecto estadístico. Los resultados dan cuenta de, por un lado, la complejidad que demanda para los formadores encontrar y formular un problema de investigación que articule sus conocimientos disciplinares; por otro, la potencialidad que parece tener el diseño y planificación de proyectos estadísticos para impulsar el desarrollo de las características que definen una competencia interdisciplinar.

Abstract The current approaches of the curricula of the Mexican Higher Secondary and Higher Education demand the development of interdisciplinary knowledge that requires the articulation of knowledge from different disciplines to address complex problems. Faced with these demands, teachers encounter challenges to, among other issues, design and implement teaching strategies that address interdisciplinary work in their classrooms. In this article, we report advances of broader research that studies the use of statistical projects as a resource to promote interdisciplinary competence. Based on the literature review, we defined four characteristics of this competence: disciplinary comprehension, disciplinary integration, reflexivity, and, production and exchange of boundary objects. This article aims to explore the development of these characteristics by teacher educators from different disciplinary areas during the planning of a statistical project. The results show, on the one hand, the complexity required the teacher educators to find and formulate a research problem that articulates their disciplinary expertise; on the other hand, the potential of the design and planning of statistical projects seems to have for promoting the development of the characteristics that define an interdisciplinary competence.

Abstract Overview and Aims: Pregnancy is an opportunity to perform postpartum contraceptive counselling, which is important to reduce the rate of unwanted pregnancies. With the purpose of knowing the attitudes, behaviours and concerns of health professionals about contraception in the postpartum period, a multicentre study was conducted in Portugal. Study design, population and methodology: A questionnaire with questions related to attitudes, practices and concerns of contraceptive counselling in pregnancy and postpartum was created and distributed in six hospital centres. This survey was intended for health professionals (physicians and nurses) and was conducted in order to ensure the anonymity and confidentiality of the participants. Descriptive study of the answers obtained. Results: There were 310 answers: 175 from doctors (56,5%) and 135 from nurses (43,5%). During pregnancy, 35.5% (n=110) always inform the woman about contraceptive options and 18.1% (n=56) if the possibility of tubal ligation arises. At discharge, the majority (81.6%, n=253) inform and advise about contraceptive options. There are 45 professionals (14.5%) who do not inform women, pointing out as reasons ‘the not appropriateness of the moment’ and ‘lack of time’. The majority of respondents consider that women should have contraceptive counselling during pregnancy (78.4%, n=243) and about one fifth (21.6%, n=67) do not. The reasons given being: ‘information should be referred to the postpartum review consultation’ and ‘the information given at discharge is sufficient’ (41.8%, n=28). In this group, 25.4% (n=17) does not intend to change their attitude, 11.9% (n=8) states that they will change their attitude e 46.3% (n=31) consider changing their attitude. Conclusions: In the population studied, contraceptive counselling during pregnancy is not universal. Although most of the professionals considered contraceptive counselling during pregnancy important, in current practice it is deferred to maternity discharge or to the postpartum review consultation.

Resumo Introdução e objetivos: A gravidez constitui uma oportunidade para realizar aconselhamento contracetivo para o pós-parto, sendo este importante para reduzir a taxa de gravidez não desejada. Com o objetivo de conhecer as atitudes, comportamentos e preocupações dos profissionais de saúde sobre a contraceção no pós-parto foi realizado um estudo multicêntrico em Portugal. Desenho do estudo, população e metodologia: Foi elaborado um questionário para profissionais de saúde (médicos e enfermeiros) que foi distribuído em seis centros hospitalares. Foi garantido o anonimato e confidencialidade dos participantes. Procedeu-se a um estudo descritivo das respostas obtidas. Resultados: Obtiveram-se 310 respostas: 175 de médicos (56.5%) e 135 de enfermeiros (43.5%). Durante a gravidez, 35.5% (n=110) informa sempre a mulher das opções contracetivas, 36.5% (n=113) informa apenas em situações especiais e 18.1% (n=56) se a hipótese de laqueação tubária se colocar. Na alta da maternidade, a maioria (81.6%, n=253) informa e orienta sobre as opções contracetivas. Existem 45 (14.5%) profissionais que não informam a mulher sobre contraceção, apontando como razões a ‘não adequação do momento’ e a ‘falta de tempo’. A maioria dos inquiridos considera que a mulher deve ter aconselhamento contracetivo durante a gravidez (78.4%, n=243) e cerca de um quinto (21.6%, n=67) considera que não, sendo os motivos apontados: ‘esta informação deve ser remetida para a consulta de revisão puerperal’ e ‘a informação dada na alta é suficiente’. Neste grupo, 25.4% não tenciona mudar a sua atitude e 46.3% pondera modificar esta atitude. Conclusões: Na população avaliada, o aconselhamento contracetivo não é universal. A maioria dos profissionais considera importante que o aconselhamento contracetivo deve ser realizado durante a gravidez. No entanto, na prática atual o aconselhamento contracetivo é diferido para a alta da maternidade ou para a consulta de revisão puerperal.

Resumen: Desde hace una década el Programa Arqueológico Huanchaco viene investigando diversos sitios en la bahía de Huanchaco, Región La Libertad, costa norte del Perú, en los que han sido recuperados un centenar de objetos metálicos asociados a diversos periodos culturales. Para este estudio se tomó una muestra de cinco objetos de metal que fueron analizados por las técnicas de microscopía óptica, electrónica y radiografías digitales. Estas piezas estuvieron asociadas a contextos estratigráficos controlados con fechados AMS que los vinculan a rangos temporales absolutos entre el 400-200 AC y el 200-500 DC. Los resultados muestran que la técnica de cobre dorado por eliminación fue empleada por los orfebres entre el 400-200 AC, lo que indicaría que su utilización es más temprana de lo que se conocía a la fecha. En este mismo estudio se muestra cómo el uso de esta técnica es continuada por sociedades posteriores hasta el 450/500 DC. Luego, orfebres de la sociedad moche (450/500 - 800/850 DC) comienzan a introducir nuevas técnicas orfebres de dorado observables en algunos objetos utilizados en Huanchaco. En suma, las muestras analizadas son reducidas, pero por provenir de contextos controlados resultan de gran importancia.

Abstract: During the last ten years, the Huanchaco Archaeological Program has investigated many sites on the Huanchaco coast, La Libertad Region, North Coast of Peru, where a hundred metallic objects associated with various cultural periods have been recovered. For this paper, we have chosen five metal artifacts associated with secure contexts and with AMS dates, which were analyzed using optical and electronic microscopy as well as digital X-rays. The absolute temporal frames for these artifacts are between 400 and 200 cal. BC (late Early Horizon) and AD 200-500. Our results indicate that between 400 and 200 cal. BC, the gilded depletion copper technique was in use, which according to our knowledge is the earliest reported for the Andean region. This study shows how the use of this technique is continued by later societies until AD 450/500. After this period, goldsmiths of the Moche society (AD 450/500 - 800/850) began to introduce new goldsmithing techniques, observable in some objects used in Huanchaco. In sum, the samples are scarce, but due to their origins from controlled contexts, they are of utmost importance.

Abstract: Purpose: To evaluate the relationships resilience - innovation - performance, and to study the mediating effect of innovation. Method: The proposed hypotheses were tested using partial least square structural equation modeling (PLS-SEM). The data was collected from 93 Mexican restaurants (SMEs). Results: Resilience and innovation exert a positive influence on business performance and the resilience influences the innovation. Also the mediation of innovation was verified. The model explained the existence of innovation practices that intensified the effect of resilience on performance. Originality: To show the resilience as the great SMEs opportunity to respond proactively during and after the crisis. Findings: The main practical implication was to demonstrate the importance of engaging higher-level activities in the SMEs for improving their chances of success. Limitations: Minimized sample size when contrasting with similar studies and finding correspondence; to use an exploratory statistical technique, whose goodness opened the possibility of using structural equations (covariances) including learning as another mediating dynamic capacity.

Resumen: El objetivo fue evaluar las relaciones resiliencia - innovación - rendimiento empresarial, y estudiar el efecto mediador de la innovación. Se utilizó el método de ecuaciones estructurales con mínimos cuadrados parciales (PLS-SEM), para probar las hipótesis. Los datos fueron recolectados de 93 restaurantes mexicanos (PYME). Los resultados validan que la resiliencia y la innovación ejercen influencia positiva en el rendimiento empresarial, la resiliencia influye en la innovación y se comprobó la mediación de la innovación. El modelo explicó la existencia de prácticas de innovación que intensificaron el efecto de la resiliencia en el rendimiento. La originalidad consiste en mostrar la resiliencia como la gran oportunidad de las PYME para responder proactivamente durante y después de la crisis. Los principales hallazgos demostraron la importancia de involucrar actividades de alto nivel en las PYME para mejorar sus posibilidades de éxito. Limitaciones: Tamaño muestral minimizado al contrastar con estudios similares y encontrar correspondencia; utilizar una técnica estadística exploratoria, que abrió la posibilidad de utilizar próximamente ecuaciones estructurales (covarianzas) incluyendo el aprendizaje como otra capacidad dinámica mediadora.

Resumo O antígeno prostático específico (PSA) em circulação é ligado à alfa-1-quimotripsina e a uma pequena fração circula livremente (PSAl). A utilidade clínica do PSA total (PSAt) e do índice de PSAl livre para o rastreamento do câncer de próstata em pacientes assintomáticos foi avaliada. PSAt, PSAl e o índice de PSAl foram quantificados em 364 pacientes estratificados por faixa etária. A frequência de valores anormais de PSAt foi de 8,79% (32/364). O grupo de 50-59 anos apresentou a maior incidência de resultados anormais (19/32). Não houve diferença estatisticamente significativa entre o PSAt e o índice PSAl (p<0,05). O índice PSAl pode potencializar o valor do PSAt para determinar a presença ou ausência de câncer de próstata. Um índice superior a 0,24 ng/mL pode ajudar a evitar ou adiar a indicação de biópsia, principalmente quando os valores de PSAt estão entre 4 e 10 ng/mL.

Resumen El antígeno prostático específico (PSA) en circulación se encuentra ligado a la alfa-1-quimiotripsina y una pequeña fracción circula de manera libre (PSAl). Se valoró la utilidad clínica del PSA total (PSAt) y el índice de PSA libre para la detección de cáncer prostático en pacientes asintomáticos. Se cuantificó el PSAt, el PSAl y el índice de PSAl en 364 pacientes estratificados por grupo de edad. La frecuencia de valores anormales de PSAt fue del 8,79% (32/364). El grupo de 50-59 años presentó la mayor incidencia de resultados anormales (19/32). No hubo diferencia estadísticamente significativa entre PSAt y el índice de PSAl (p<0,05). El índice PSAl puede potencializar el valor del PSAt para determinar la presencia o ausencia de cáncer prostático. Un índice superior a 0,24 ng/mL puede ayudar a evitar o posponer la indicación de biopsia, principalmente cuando los valores de PSAt están entre 4 y 10 ng/mL.

Abstract Circulating prostate-specific antigen (PSA) is bound to alpha-1-chymotrypsin and a small fraction is free (PSAl). The clinical utility of the total PSA (PSAt) and the PSAl index for prostate cancer screening in asymptomatic patients was assessed. PSAt, PSAl and the PSAl index were quantified in 364 patients stratified by age group. The frequency of abnormal PSAt values was 8.79% (32/364). The 50-59 year-old group presented the highest incidence of abnormal results (19/32). There was no statistically significant difference between PSAt and the PSAl index (p<0.05). The PSAl index can potentiate the PSAt value to determine the presence or absence of prostate cancer. An index greater than 0.24 ng/mL can help to avoid or postpone the indication for a biopsy, especially when the PSAt values are between 4 and 10 ng/mL.

Resumo: O objetivo foi estimar a prevalência do atraso nas três doses da vacina tetravalente (DTP+Hib) em crianças de 12 a 23 meses de idade, no Brasil, por meio dos dados da Pesquisa Nacional de Saúde (PNS) de 2013 e descrever o atraso em cada uma das doses segundo variáveis sociodemográficas, utilização de serviços e intervenções públicas de saúde. Foram utilizados dados da PNS, estudo transversal realizado em 2013. O desfecho foi o atraso pelo menos em uma das três doses da vacina tetravalente. Considerou-se como atraso a dose recebida pelo menos 30 dias após a data preconizada, segundo informação da caderneta de vacinação. A prevalência do atraso foi descrita segundo variáveis sociodemográficas e utilização de serviços de saúde. Realizou-se análise descritiva obtendo-se frequências absolutas e relativas e seus respectivos intervalos de 95% de confiança. Das 2.016 crianças com informações coletadas, 1.843 foram analisadas. A prevalência de atraso de pelo menos uma dose da vacina foi de 44%. Observou-se atraso de 14,8% na primeira, 28,8% na segunda e 45,4% na terceira dose, sendo que 10% das crianças tiveram atraso nas três doses. Maiores prevalências de atraso foram encontradas em crianças do sexo masculino, de cor da pele parda, pertencentes ao quintil mais pobre de riqueza, moradores da zona rural e da Região Norte do Brasil. Evidenciou-se alta prevalência de atraso na vacina tetravalente (DTP+Hib) em crianças de 12 a 23 meses do Brasil, sendo maior na terceira dose.

Abstract: The study aimed to estimate the prevalence of delay in the three doses of quadrivalent vaccine (DTP+Hib) in children 12 to 23 months of age in Brazil, based on data from the Brazilian National Health Survey (PNS) of 2013 and to analyze the delay in each of the doses according to sociodemographic variables and use of health services and public health interventions. The data are from the PNS a cross-sectional study performed in 2013. The outcome was delay in at least one of the three doses of the quadrivalent vaccine. Delay was defined as a dose received at least 30 days after the recommended date according to information on the child’s vaccination card. Prevalence of delay was analyzed according to sociodemographic variables and use of health services. A descriptive analysis was performed to obtain absolute and relative frequencies and their respective 95% confidence intervals. Of the 2,016 children with information collected, 1,843 were analyzed. The prevalence of delay in at least one dose of the vaccine was 44%. There was a delay of 14.8% in the first dose, 28.8% in the second, and 45.4% in the third, and 10% of the children had delays in all three doses. Higher prevalence of delay was associated with male gender, brown skin color, the poorest income quintile, and residence in rural areas and the North of Brazil. The study revealed high prevalence of delay with the quadrivalent vaccine (DTP+Hib) in children 12 to 23 months of age in Brazil, with the highest delay in the third dose.

Resumen: El objetivo fue estimar la prevalencia del atraso en las tres dosis de la vacuna tetravalente (DTP+Hib) en niños de 12 a 23 meses de edad, en Brasil, mediante los datos de la Encuesta Nacional de Salud (PNS) de 2013 y describir el retraso en cada una de las dosis, según variables sociodemográficas, utilización de servicios e intervenciones públicas de salud. Se trata de un estudio transversal, realizado en 2013, con datos de la PNS. El resultado fue el retraso por lo menos en una de las tres dosis de la vacuna tetravalente. Se consideró como un atraso la dosis recibida por lo menos 30 días tras la fecha prefijada, según la información de la cartilla de vacunación. La prevalencia del atraso fue descrita según variables sociodemográficas y utilización de servicios de salud. Se realizó un análisis descriptivo, obteniéndose frecuencias absolutas y relativas, así como sus respectivos intervalos de 95% de confianza. De los 2016 niños con información recogida, se analizaron 1843. La prevalencia de atraso de por lo menos una dosis de la vacuna fue de un 44%. Se observó un retraso de 14,8% en la primera, un 28,8% en la segunda y un 45,4% en la tercera dosis, siendo que un 10% de los niños sufrieron atraso en las tres dosis. Las mayores prevalencias de atraso se encontraron en niños de sexo masculino, mestizos, pertenecientes al quintil más pobre de riqueza, habitantes de la zona rural y de la Región Norte de Brasil. Se evidenció una alta prevalencia de atraso en la vacuna tetravalente (DTP+Hib) en niños de 12 a 23 meses de Brasil, siendo mayor en la tercera dosis.

Abstract: There is a current expectation of instruments for periodontal condition surveillance worldwide. The present study aimed to validate the Oral Health Questions Set B (OHQB) for the Brazilian Portuguese and evaluate its temporal stability. This is a sequential mixed-method investigation. After the forward-backward translation process to the Brazilian Portuguese, the OHQB Brazil (OHQB-Br) was applied to 156 participants (39.5 ± 14.14 years; 51.9% males). In sequence, through a full-mouth six-sites/teeth examination and in accordance with the original instrument, the periodontal diagnosis was obtained (March 2020). In January 2021, the OHB-BR was reapplied (n = 71). Ordinal alpha and McDonald's omega tested the internal consistency of the OHQB-Br. Temporal stability was investigated [Spearman correlation, intraclass correlation coefficient (ICC), and the Bland-Altman]. The concurrent validity was also verified, considering the periodontal clinical diagnosis (Kruskal Wallis). The ordinal alpha (0.69) and McDonald's omega (0.73) coefficients showed an adequate internal consistency of the OHQB-Br. The OHQB-Br temporal stability was high, as demonstrated by the Spearman coefficient (0.80) and ICC (0.79) and by the Bland-Altman plot. A concurrent validity showed a direct relationship between the OHQB-Br and the clinical condition of no periodontitis, mild, moderate, and severe periodontitis (p < 0.05). Because the OHQB-Br shows internal validity, temporal stability, and adequately identifies periodontal health and moderate/severe periodontitis, the instrument might represent an important tool, at the public level or other settings, for periodontal surveillance in Brazil.

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.

ABSTRACT River basins play a critical role in ecosystem services and their status regulate the associated productivity. Anthropogenic activities along with other environmental perturbation influence the vulnerability level of that important water resource, disturbing in a short time, water quality. The aim of this work is to generate an approach to Toltén basin characterization with benthonic macroinvertebrates, physicochemical and bacterial components as indicators of variation in water quality close to human populations and the sectors furthest from them, selecting for this purpose two areas (up and downstream of the basin). We used an ANOSIM two-way analysis to relate abiotic and biotic data and for diversity and biotic index (ChBMWP) we analyzed the benthic macroinvertebrate composition. A principal component analysis for environmental variables strongly separated the analyzed zones by season as the first principal component, showing a clear increase in temperature and electrical conductivity values in spring season. Meantime the pH parameter was observed with interesting variation for longitudinal gradient with incremental values in upstream area. The biotic indexes applied to the samples between seasons reflexes a similar diversity between analyzed sites in upstream with no differences showing a low diversity of macroinvertebrates. However, a significant increase was detected during spring in downstream zone. On the other hand, Pseudomonas genus increase between the most representative microbiological genera in the basin. Our results reinforce the importance not only of frequent seasonal monitoring program but also the critical role of collecting data on total transect basin length to regulate the human activities associated to basin and to protect the water quality.

Resumen (Introducción): Actualmente, el manejo adecuado de los residuos es uno de los retos ambientales a los que se enfrentan todos los países, en sus etapas de recolección, tratamiento y disposición. Generalmente, en cada nación, las autoridades gubernamentales prestan especial atención a las grandes ciudades, discriminando a localidades rurales; esto, derivado de una falta de recurso económico y técnico para tratar y disponer adecuadamente los residuos en estos sitios, por lo cual quedan como responsables las poblaciones de dar un manejo propio a sus residuos; sin embargo, no se tienen documentadas sus prácticas para tal fin. (Objetivo): Se realizó un diagnóstico del manejo actual que se les da a los residuos en tres localidades rurales con grado medio de marginación, correspondientes a Colonia Hidalgo, Ejido Zaragoza y Plan de Guadalupe en Sombrerete (Zacatecas, México). (Metodología): La información se obtuvo de la aplicación de un cuestionario tipo encuesta a una muestra representativa de cada una de las localidades. (Resultados): Se determinó que la quema incontrolada de residuos es la práctica más realizada; los residuos orgánicos se utilizan como alimento para ganado en condiciones insalubres; los residuos susceptibles a reciclaje se separan, pero solo se vende una parte; los sacos de fertilizantes se reutilizan, y los contenedores de pesticidas se queman en condiciones incontroladas; prácticas que afectan el ambiente y la salud de la gente. (Conclusiones): Se evidencia la falta de atención por parte de autoridades gubernamentales en el manejo de residuos en localidades rurales y marginadas, donde se recurre a prácticas insostenibles.

Abstract (Introduction): The proper management of waste is one of the environmental challenges currently facing worldwide, in its stages of collection, treatment and disposal. Generally, in each nation the government authorities give special attention to large cities, discriminating against rural localities due to the lack of economic and technical resources to treat and to dispose the waste properly in these sites, being the settlers responsible to give proper management to their waste, however, the practices that they perform are not reported. (Objective): A diagnosis of the current management of waste by settlers of three rural localities with a medium degree of marginalization, corresponding to Colonia Hidalgo, Ejido Zaragoza and Plan de Guadalupe in Sombrerete (Zacatecas, Mexico), was performed. (Methodology): The information was obtained from the application of a survey-type questionnaire to a representative sample of each locality. (Results): It was determined that the uncontrolled burning of waste is the most performed practice; organic waste is used as livestock feed in non-sanitary conditions; recyclable waste is separated, but only part of it is sold; fertilizer sacks are reused, and pesticide containers are burned in uncontrolled conditions; practices that affect the environment and the health of the settlers. (Conclusions): The lack of attention from government authorities in waste management in rural and marginalized localities is evident, so that the settlers develop unsustainable practices.

Background: Previous studies have shown a decrease in the maternal mortality (MM) rates in Chile, with a trend towards stability since 2001. However, some of its associated causes such as high blood pressure, obesity, or maternal age, have increased in the last years. Aim: To describe the trend and characteristics of MM in Chile between 1990 and 2018. Material and Methods: MM rates were calculated using death records available at the website of the Department of Health Statistics of the Ministry of Health, using the codes 630 to 679 of the International Classification Diseases (ICD)-9 (630-679) and O00-O99 from ICD-10. Live births were obtained from vital statistics of the National Statistics Institute (INE). The age at the time of death and the causes were recorded. Polynomial and Prais-Winsten modelings were applied. Results: There were 1,728 maternal deaths with an overall rate for the period of 23 / 100,000 live births. An inflection of the trend was observed in 2003, with a decrease between 1990-2003 and an increase between 2004-2018. While in the 1990-2003 period all age groups decreased their rate, in 2004-2018 it increased significantly in the 20-34 age group. Concerning the causes, “other obstetric conditions not classified elsewhere” showed a steady upward trend, particularly the late maternal deaths or deaths from sequelae of obstetric causes (O96-O97). Conclusions: MM rates increased in Chile in recent years, mainly due to the increase in women aged 20 to 34 years and in causes referred to as “other obstetric conditions not classified elsewhere.” It is possible that changes in risk factors and in the registries could explain this increase.

ABSTRACT The absorption capacity allows companies to combine the knowledge extracted from the outside with the previously developed inside to respond to the constant changes in their environment. The purpose was to determine the influence of the acquisition, assimilation, transformation and exploitation of knowledge and its impact on the organizational response capacity of small companies. A sample of 132 small Mexican companies was used. The questionnaire’s quality was confirmed. A hierarchical regression model was determined. The results showed a significant positive relationship between acquisition, assimilation, transformation, and exploitation with the response capacity of the organization. Nevertheless, the multiple regression model excluded the exploitation of knowledge. This means that small companies benefit from external knowledge to strengthen their internal baggage, but they do not obtain the benefits of exploitation by not materializing knowledge abroad through innovation. This research reveals the SMEs need to stimulate and take advantage of their absorption capacity in the development of new products or services that respond to an increasingly demanding market.

RESUMEN La capacidad de absorción permite a las empresas combinar el conocimiento extraído del exterior con el previamente gestado al interior para dar respuesta a los constantes cambios de su entorno. El objetivo fue determinar la influencia de la adquisición, asimilación, transformación y explotación del conocimiento y su impacto en la capacidad de respuesta organizacional de las pequeñas empresas. Una muestra de 132 pequeñas empresas mexicanas permitió un análisis factorial que confirmó la calidad métrica del cuestionario empleado, así como la realización de un modelo de regresión múltiple. En las regresiones simples se comprueba una relación positiva significativa entre la adquisición, asimilación, transformación y explotación con la capacidad de respuesta de la organización. El modelo de regresión múltiple excluyó la explotación del conocimiento, lo que implica que las pequeñas empresas se benefician del conocimiento externo para fortalecer su bagaje interno, mejorar sus procesos y rutinas, pero conjuntamente no aprovechan las bondades de la explotación del conocimiento. Esta investigación revela a las PYME la necesidad de estimular y aprovechar su capacidad de absorción para desarrollar nuevos productos o servicios que den respuesta a un mercado cada vez más exigente.
