ABSTRACT Product innovation is essential for the growth and profitability of SMEs. Existing scientific evidence suggests that firm strategy and participation in business networks could influence this innovation. In turn, participation in networks might influence the configuration and allocation of the organizational resources and capabilities that help shape firm strategy. Hence, this study analyzes business networks as a mediator between firm strategy and product innovation in SMEs. It uses a sample of 205 SMEs from Costa Rica compiled by the Global Competitiveness Project. The proposed mediation is tested using OLS regression equations. The findings show that business networks do indeed play a mediating role in the relationship between firm strategy and product innovation, which has implications for SMEs in terms of the relevance of participating in such networks and also for public policymakers regarding the importance of managing them. turn Hence 20 Project equations them 2

RESUMO A inovação de produtos é essencial para o crescimento e a rentabilidade das pequenas e médias empresas (PMEs). As evidências sugerem que tanto a estratégia empresarial quanto a participação em redes podem influenciar a inovação de produtos, enquanto a participação em redes também pode influenciar a configuração e a alocação de recursos e capacidades que ajudam a moldar a estratégia. O presente estudo visa analisar as redes empresariais como uma variável mediadora entre estratégia e inovação de produtos nas PMEs. O estudo utiliza uma amostra de 205 PMEs costa-riquenhas, coletada pelo Global Competitiveness Project. A mediação é testada usando um modelo de regressão. Os resultados mostram que as redes desempenham um papel mediador na relação entre a estratégia empresarial e a inovação de produtos. As conclusões têm implicações para as PMEs sobre a relevância da participação em redes que permeiam a estratégia e para os formuladores de políticas sobre a importância de gerenciar tais redes. .

ABSTRACT Background The pathway that links good communication skills and better health outcomes is still unclear. However, it is known that the way that physicians and patients communicate with each other has direct consequences on more “proximal outcomes”, such as perceptions of physician empathy and patient satisfaction. However, which specific communication skills lead to those patient outcomes is still unknown. In this study, the authors aimed to analyze which specific patient and physician communication skills are correlated to patients’ satisfaction with care and patient-perceived physician empathy. Methods The authors classified and quantified verbal and nonverbal communication of second-year internal medicine residents and their patients through video recordings of their consultations. Patients also rated their satisfaction with care and the physician's empathy for them. Results Using a linear regression model, the authors identified that patients’ and physicians’ expressions of disapproval, physicians’ disruptions, and patients’ use of content questions negatively correlated to patients’ satisfaction and patient-perceived physician empathy. Conversely, patient affective behaviors and the physician's provision of advice/suggestion were positively correlated to at least one of the patient-measured outcomes. Conclusion Our findings point to the importance of physicians’ attentiveness to patients’ communication cues. Training physicians to interpret those cues could help develop more satisfactory and empathic therapeutic relationships. unclear However proximal outcomes, , outcomes” unknown study patientperceived perceived secondyear second year consultations s them model disapproval disruptions Conversely advicesuggestion advice suggestion patientmeasured measured relationships

Resumo Nematódeos do gênero Aplectana Railliet & Henry, 1.916, são parasitos comuns do trato digestório de anfíbios e répteis na região Neotropical. Durante um levantamento de parasitos em Boana boans (Linnaeus, 1.758), foram encontrados espécimes de nematódeos com características de Aplectana. Observou-se um conjunto de características que diferencia a espécie deste estudo de outros congêneres, e o presente estudo descreve uma nova espécie de Aplectana parasito de B. boans, usando-se microscopia de luz e microscopia eletrônica de varredura. Aplectana pella n. sp. possui alas laterais e papilas somáticas em machos e fêmeas; os machos têm espículos curtos e iguais e gubernáculo ausente. O arranjo de pares de papilas caudais o diferencia de outras espécies (2 pré-cloacais, 1 adcloacal e 5 pós-cloacais +1 ímpar não pareada). Nas fêmeas, a vulva é simples, sem lábios proeminentes, e situada na região equatorial do corpo. Este é o primeiro registro do gênero Aplectana parasitando B. boans e a 58ª espécie descrita para esse gênero. Além disso, foi adicionado o padrão de papilas pré-cloacais de A. delirae e, com base em características morfológicas e morfométricas, foi proposta a realocação de Aplectana longa para o gênero Oxyascaris.

Abstract Nematodes of the genus Aplectana Railliet & Henry, 1916 are common parasites of the digestive tract of amphibians and reptiles in the Neotropical region. During a parasite survey on Boana boans (Linnaeus, 1758), we found specimens of nematodes with Aplectana characteristics. We observed a set of characteristics that differs the species of our study from its congeners, and the present study describes a new species of Aplectana parasite of B. boans using light microscopy and scanning electron microscopy. Aplectana pella n. sp. has lateral alae and somatic papillae in males and females; males have equal short spicules, and the gubernaculum is absent. The arrangement of pairs of caudal papillae also differs from other species (2 precloacal,1 adcloacal, and 5 postcloacal+1 unpaired). In females, the vulva is simple, with non-prominent lips, and equatorial. This is the first record of the genus Aplectana parasitizing B. boans and the 58th species described for this genus. Additionally, we added the precloacal papillae pattern of A. delirae, and based on morphological and morphometric characteristics, we propose the reallocation of Aplectana longa to the genus Oxyascaris.

Resumo Fundamento Tem sido observado um grande avanço nas técnicas e nos dispositivos para a realização de intervenções coronárias percutâneas (ICP) em oclusões totais coronarianas crônicas (OTC), mas existem poucos dados da prática do mundo real em países em desenvolvimento. Objetivos Relatar as características clínicas e angiográficas, os aspectos dos procedimentos e os resultados clínicos da ICP de OTC em centros dedicados a esse procedimento no Brasil. Métodos Os pacientes incluídos foram submetidos à ICP de OTC em centros participantes do LATAM CTO Registry, um registro multicêntrico latino-americano dedicado à coleta prospectiva desses dados. Os critérios de inclusão foram procedimentos realizados no Brasil, idade acima de 18 anos e presença de OTC com tentativa de ICP. A definição de OTC foi lesão de 100% em uma artéria coronária epicárdica, conhecida ou estimada como tendo pelo menos 3 meses de evolução. Resultados Foram incluídos dados de 1.196 ICPs de OTC. Os procedimentos foram realizados principalmente para controle da angina (85%) e/ou tratamento de uma grande área isquêmica (24%). A taxa de sucesso técnico foi de 84% e foi alcançada com técnicas de fios anterógrados em 81%, dissecção/reentrada anterógrada em 9% e retrógrada em 10% dos procedimentos. Os eventos cardiovasculares adversos intra-hospitalares ocorreram em 2,3% dos casos, sendo a mortalidade de 0,75%. Conclusões As OTC podem ser tratadas no Brasil por intervenção coronária percutânea de forma efetiva e com baixas taxas de complicações. O desenvolvimento científico e tecnológico observado nessa área na última década reflete-se na prática clínica de centros brasileiros dedicados a essa técnica.

Abstract Background Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries. Objectives To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil. Methods Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data. Inclusion criteria were procedures performed in Brazil, age 18 years or over, and presence of CTO with PCI attempt. CTO was defined as a 100% lesion in an epicardial coronary artery, known or estimated to have lasted at least 3 months. Results Data on 1196 CTO PCIs were included. Procedures were performed primarily for angina control (85%) and/or treatment of moderate/severe ischemia (24%). Technical success rate was 84%, being achieved with antegrade wire approaches in 81% of procedures, antegrade dissection and re-entry in 9%, and retrograde approaches in 10%. In-hospital adverse cardiovascular events occurred in 2.3% of cases, with a mortality rate of 0.75%. Conclusions CTOs can be treated effectively in Brazil by using PCI, with low complication rates. The scientific and technological development observed in this area in the past decade is reflected in the clinical practice of dedicated Brazilian centers.

ABSTRACT The 30-s Chair-Stand (CS30s) and the Timed Up and Go (TUG) are functional tests designed to provide information about lower limbs’ muscle strength and functional agility in the elderly. Although both tests are intended to assess different aspects of functional fitness, the level of shared variance between these tests has not been determined yet. This study aimed to verify the correlation between the TUG and the CS30s. Forty-seven healthy women volunteered to participate in this study. The participants participated in a 60-minute water exercise program that occurred twice weekly for at least 6 months. The CS30s and the TUG were administered to each subject, respectively, always in this order. The results from Pearson’s correlation were calculated using the maximal number of repetitions performed in the CS30s test and the time spent performing the TUG test. There was a significant but low correlation (r = -.563; p < .05). A shared variance of 31.7% was observed, so it is possible to speculate that these tests are related to different neuromuscular demands. The scores obtained from the CS30s were 8.1% higher than the ones found in the reference values from the literature for this target group, while the scores from the TUG were similar.

RESUMO Os testes funcionais de levantar-se e se sentar da cadeira de 30s (TLS30s) e o teste Timed Up and Go (TUG) são utilizados com objetivo de fornecer informações sobre o desempenho da força muscular de membros inferiores e a agilidade funcional em idosos, respectivamente. Embora ambos os testes tenham como objetivo avaliar diferentes aspectos da aptidão funcional, o nível de variância comum entre esses testes ainda não foi determinado. Assim, o presente estudo tem como objetivo verificar o nível de correlação entre os desempenhos nos testes TUG e o TLS30s e comparar os resultados com valores de referência para indivíduos idosos ativos, independentes e do sexo feminino. Participaram voluntariamente deste estudo 47 mulheres idosas saudáveis, que realizavam atividade física (hidroginástica) há pelo menos seis meses, duas vezes por semana e com duração de 60 minutos cada sessão. As idosas foram submetidas primeiramente ao teste TLS30s e na sequência ao TUG. O coeficiente de correlação de Pearson foi calculado entre o número máximo de repetições realizadas no TLS30s e o tempo gasto para executar o teste TUG. Foi verificada uma correlação significativa, porém baixa (r = -.563; p < .05) entre os dados obtidos nos testes. Baseado na baixa variância comum (31.7%) foi possível concluir que os testes realizados apresentam exigências distintas para o sistema neuromuscular. O desempenho do grupo amostra foi superior para o TLS30s comparado com os valores de referência, enquanto para o TUG o desempenho foi similar aos valores de referência.

Resumo As Unidades de Conservação são um instrumento da Política Nacional de Meio Ambiente que determinou a criação de espaços para a proteção e a garantia do equilíbrio ecossistêmico no território brasileiro. A Área de Proteção Ambiental (APA) do rio Uberaba é uma Unidade de Conservação criada com o objetivo de garantir a qualidade das águas do rio Uberaba, sendo este o manancial de abastecimento público da cidade de Uberaba - MG. É caracterizada como uma unidade de conservação de uso sustentável, e algumas atividades altamente impactantes vêm sendo realizadas na sua área, com isso, causando diversas alterações no meio, tais como erosão, eutrofização de cursos d’água e alterações na qualidade e quantidade de água. O objetivo deste estudo foi estimar as perdas de solo e diagnosticar as áreas com potencial natural de erosão (PNE) utilizando a Equação Universal de Perda de Solo (EUPS), o Sistema de Informação Geográfica (SIG) e os produtos de sensoriamento remoto. O PNE apresentou valores baixos (<100 t ha-1 ano-1) em 38,72% da APA, médios (100-200 t ha-1 ano-1) em 31,29% e os valores alto (200-600 t ha-1 ano-1), muito altos (600 -1000 t ha-1 ano-1) e extremamente altos (>1.000 t ha-1 ano-1) totalizaram 29,99% da APA. As estimativas de perda de solo pela erosão hídrica com valores abaixo de 5 t ha-1 ano-1 representam 43,81% da APA. Estimativas de perdas entre 5-10 t ha-1 ano-1 ocorrem em 12,22% da área, de 10-20 t ha-1 ano-1 em 21,82%, entre 20-50 t ha-1 ano-1 em 17,89%, 50-100 t ha-1 ano-1 em 3,92% e perdas superiores a 100 t ha-1 ano-1 em 0,34% da APA. O uso das geotecnologias e da Equação Universal de Perda de Solo possibilitou identificar espacialmente os locais em que ocorrem os maiores e os menores potenciais riscos de erosão, o que permitiu estimar as taxas de perda de solo ao longo da APA do rio Uberaba.

Abstract Conservation Units are National Environment Policy instruments that determined the creation of areas for protection and guarantee of ecosystem balance in the Brazilian territory. The Uberaba River Environmental Protection Area (APA) is a water conservation unit in the city of Uberaba - MG. It is characterized as a sustainable use conservation unit, and some highly impacting activities have been occurring in this area, leading to erosion, water eutrophication, and changes in water quality and quantity. The aims of this study were to evaluate soil losses and to diagnose areas of natural potential for erosion (PNE) using the Universal Soil Loss Equation (USLE), the Geographic Information System (GIS), and remote sensing products. Adjusted PNE was low (<100 t ha-1 year-1) in 38.72% of the APA and moderate (100-200 t ha-1 year-1) in 31.29% of the area. High (200-600 t ha-1 year-1), very high (600-1000 t ha-1 year-1), and extremely high indexes (> 1000 t ha-1 year-1) were observed in 29.99% of the APA. Estimates of soil loss due to water erosion below 5 t ha-1 year-1 represented 43.81% of the APA. Estimated losses between 5 and 10 t ha-1 year-1 occur in 12.22% of the area; from 10 to 20 t ha-1 year-1, 21.82% of the area; between 20 and 50 t ha-1 year-1,17.89% of the area; from 50 to 100 t ha-1 year-1, 3.92% of the area; and losses over 100 t ha-1 year-1 involved 0.34% of the APA.

Abstract Introduction Coronavirus disease 2019 (COVID-19) has claimed millions of lives. Adequate protection of the professionals involved in patient care is essential in the battle against this disease. However, there is much uncertainty involving safety-relarted topics that are of particular interest to the rhinologist in the context of COVID-19. Objective To evaluate the current evidence regarding three safety-related topics: mask and respirator use, performance of nasal endoscopic procedures, and use of topical nasal and intranasal medications (saline irrigation and nasal corticosteroids). Methods A literature review was performed on the PubMed, Scopus, and Cochrane databases, with standardized search queries for each of the three topics of interest. Results In total, 13 articles on mask use, 6 articles on the safety of nasal corticosteroids, 6 articles on the safety of nasal endoscopic procedures, and 1 article on nasal irrigation with saline solution were included in the final analysis. Conclusion N95 respirators are essential for the adequate protection of otolaryngologists. If reuse is necessary, physical methods of sterilization must be employed. No evidence was found to contraindicate the use of nasal corticosteroids, whether acute (in the management of sinonasal inflammatory conditions) or continued (in patients who use them chronically). Nasal irrigation with saline solution apparently does not increase the risk in the context of COVID-19. Nasal endoscopic procedures should only be performed after testing the patient for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the surgical team must wear full personal protective equipment to prevent aerosol exposure.

ABSTRACT The aim if this study was to characterize strains of E. coli isolated from Rattus norvegicus belonging to a level 1 animal facility. Faecal samples were taken from 13 rats. Five colonies were randomly selected from the primary growth of the culture of each sampled individual. Biochemical tests were performed and the pathotype and phylogroup were established in the strains that were identified as E. coli by means of the PCR technique. In addition, tests for biofilm formation and antimicrobial susceptibility were performed. Results showed that 65% (26/40) of the isolated strains corresponded to E. coli and all clustered in phylogroup B2. Six of the E. coli strains were resistant to nitrofurantoin (23%), four were resistant to ampicillin (15%), and three strains were resistant to cefozolin (11%). None showed the formation of biofilms, nor the amplification of genes related to any pathotype. The results denote that E. coli belonging to the biota of laboratory rats presents resistance to antibiotics and the presence of the chuA and yjaA genes associated with the B2 phylogroup strains related to extraintestinal diseases.

RESUMEN El objetivo del trabajo fue caracterizar cepas de E. coli aisladas de Rattus norvegicus pertenecientes a un bioterio de nivel 1. Se tomaron muestras de heces a 13 ratas. Se seleccionaron cinco colonias al azar del crecimiento primario del cultivo de cada individuo muestreado. Se realizaron pruebas bioquímicas y en las cepas que fueron identifica- das como E. coli se estableció el patotipo y el filogrupo por medio de la técnica de PCR. Además, se realizaron pruebas para la formación de biopelículas y la susceptibilidad antimicrobiana. El 65% (26/40) de las cepas aisladas correspondieron a E. coli. El análisis mediante PCR mostró que todas se agruparon en el filogrupo B2. Seis de las cepas de E. coli presentaban resistencia a nitrofurantoina (23%), cuatro fueron resistentes a ampicilina (15%) y en tres cepas se observó resistencia a cefozolina (11%). Ninguna mostró la formación de biopelículas, ni la amplificación de genes relacionados a algún patotipo. Los resultados denotan que E. coli perteneciente a la biota de ratas de bioterio presenta resistencia a antibióticos y la presencia de los genes chuA y yjaA que incluyen a las cepas en el filogrupo B2 relacionado a enfermedades extraintestinales.

ABSTRACT The aim of this article is to analyze the main dangers that Central American and Mexican migrants confront when they resort to smugglers to get to the United States, and how the adversities they face are interpreted in light of two of the most outstanding discourses about smuggling. Based on surveys about migration done along Mexico’s northern and southern borders, the authors examine this phenomenon as well as the figures for thefts, assaults, and abandonment that these people suffer at the hands of smugglers.

RESUMEN El objetivo de este trabajo es analizar los principales peligros que los migrantes centroamericanos y mexicanos enfrentan al recurrir a los coyotes en su intención de llegar a Estados Unidos, y cómo las adversidades que afrontan se interpretan a la luz de dos de los más destacados discursos respecto del coyotaje. Con base en las Encuestas sobre Migración en las Fronteras Sur y Norte de México se examina este fenómeno, así como también las cifras de robos, asaltos y abandonos de que son víctimas estas personas por parte de los coyotes.

ABSTRACT Introduction: Adherence is crucial to the development of most Escherichia coli infections. Three different adherence patterns have been described for pathotypes of this species: localized, diffuse and aggregative adherence, based on the specific clinical pathogenic processes they bring about. However, few studies have been conducted about in vitro adherence phenotypes of E. coli isolated from the environment. Objective: Determine the adherence phenotypes of E. coli strains isolated from freshwater ecosystems in Havana. Methods: An analysis was conducted of 108 E. coli strains isolated from the rivers Almendares, Quibú and Luyanó in Havana. Determination was made of the adherence pattern by adherence assays in HEp-2 cell line cultures, as well as of the serotype for each strain. Results: Of the E. coli strains isolated, 25% were adherent and 75% were not. Twenty-two strains displayed the typical diffusely adherent pattern and five displayed aggregative adherence. Strains exhibiting the two adherence patterns were found in the three rivers evaluated. The strains contained 24 different serotypes. Conclusions: The environmental E. coli strains circulating in these ecosystems were found to have adherent characteristics whose pathogenicity implies a potential risk to human health, particularly in childhood.

RESUMEN Introducción: El proceso de adherencia es fundamental en el desarrollo de la mayoría de las infecciones ocasionadas por Escherichia coli. Para los patotipos de esta especie se describen tres patrones de adherencia diferentes: adherencia localizada, adherencia difusa y adherencia agregativa, los cuales se relacionan con los procesos patogénicos específicos que ocasiona en la clínica. Sin embargo, son pocos los estudios en relación con los fenotipos de adherencia in vitro de E. coli aisladas del ambiente. Objetivo: Determinar los fenotipos de adherencia de cepas de E. coli aisladas de ecosistemas dulceacuícolas de La Habana. Métodos: Se analizaron 108 cepas de E. coli aisladas de los ríos Almendares, Quibú y Luyanó de La Habana. Se determinó el patrón de adherencia mediante ensayos de adherencia en cultivo celular de la línea HEp-2 así como el serotipo de cada cepa. Resultados: El 25 % de las cepas de E. coli aisladas fueron adherentes y el 75 % fueron no adherentes. Veintidós cepas mostraron el típico patrón de adherencia difusa y cinco cepas mostraron una adherencia agregativa. Se encontraron cepas de los dos patrones de adherencia en los tres ríos evaluados. Las cepas presentaron 24 serotipos diferentes. Conclusiones: Se demostró que las cepas de E. coli ambientales circulantes en estos ecosistemas presentan características adherentes, cuya patogenicidad implica un riesgo potencial para la salud humana, especialmente en edades pediátricas.

Abstract Objective: to analyze the agro-export enclave social basis through the study of the social relations of production in two agro-export regions of Baja California Sur, where global and regional capitals converge with the transfer of workers in order to sustain the production process. Methodology: consists of two representative surveys conducted in agricultural day-laborers’ camps in two regions of Baja California Sur: Vizcaíno Valley and Santo Domingo Valley between 2014 and 2015. Data analysis was made through descriptive statistics and a logistic regression model. Results: social relations of production go beyond the workplace, with forms of precarious exploitation, and include the control of mobility and residence. Limitations: the generalization scope due to the very specific connections that converge in the regions of study. Value: its contribution to the discussion on the scarce regional connections of global capitals and their effect on the production and reproduction of inequalities at the global and regional level. Conclusions: the relations of exploitation in global regions, such as this case of study, are based on residence control and work intensification, with effects on life expectancy reduction and endanger workers’ and their families social reproduction.

Resumen Objetivo: analizar las bases sociales del enclave agroexportador a través del estudio de las relaciones sociales de producción en dos regiones agroexportadoras de Baja California Sur, donde convergen capitales globales y regionales con el traslado de trabajadores para sostener el proceso productivo. Metodología: consiste de dos encuestas representativas realizadas entre 2014 y 2015 en campamentos de trabajadores jornaleros agrícolas en el valle de Vizcaíno y el valle de Santo Domingo. Los datos se analizaron mediante estadística descriptiva y un modelo de regresión logística binaria. Resultados: las relaciones sociales de producción van más allá del espacio laboral, con formas de explotación precaria, y abarcan el control de la movilidad y de la residencia. Limitaciones: el alcance de la generalización del estudio dadas las conexiones tan específicas que confluyen en las regiones estudiadas. Valor: el aporte a la discusión sobre las escasas conexiones regionales de los capitales globales y su efecto en la producción y reproducción de las desigualdades a escala regional. Conclusiones: las relaciones de explotación en regiones globales, como las estudiadas, se sustentan en el control de la residencia y la intensificación del trabajo, lo cual tiene efectos en la reducción de las expectativas de vida de los trabajadores y pone en peligro la reproducción social de los trabajadores y sus familias.

Abstract Background There has been an increase in the number of cases of Takotsubo syndrome (TTS) and of scientific publications on the theme over the last years. However, little is known about the status of this disease in Brazilian hospitals. Objective To assess mortality and major adverse cardiovascular events (MACE) during hospitalization and follow-up of TTS patients seen in a tertiary hospital in Brazil. Methods This was a retrospective, observational study on 48 patients. Clinical data, signs and symptoms, complementary tests, MACE and all-cause mortality were assessed on admission and during follow-up. Kaplan-Meier curves were used for analysis of all-cause mortality and risk for MACE at median follow-up. The 95% confidence interval was also calculated for a significance level of 5%. Results Mean age of patients was 71 years (SD±13 years), and most patients were women (n=41; 85.4%). During hospitalization, four patients (8.3%) died and five (10.4%) developed MACE. At median follow-up of 354.5 days (IQR of 81.5-896.5 days), the risk of all-cause mortality and MACE was 11.1% (95% CI= 1.8-20.3%) and 12.7% (95% CI= 3.3-22.3%), respectively. Conclusion TTS was associated with high morbidity and mortality rates in a tertiary hospital in Brazil, which were comparable to those observed in acute coronary syndrome. Therefore, the severity of TTS should not be underestimated, and new therapeutic strategies are required. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0
