Analysis of cervical sagittal balance in patients neck pain and no neck pain / Análise do equilíbrio sagital cervical em pacientes com e sem cervicalgia / Análisis del equilibrio sagital cervical en pacientes con y sin cervicalgia

ABSTRACT Introduction: Sagittal balance was measured by Hardacker`s et al. using the occipital method COBB C1-C2, C2-C3, C3-C4, C4-C5, C5-C6, C6-C7 in a sample of asymptomatic patients without neck and shoulder pain. In other recent studies, measurements of cervical sagittal balance included several radiographic parameters. Objective: To compare the cervical sagittal balance in groups of patients with and without neck pain submitted to cervical radiography with the upper limbs in flexion. Methods: This is a cross-sectional, quantitative, prospective, descriptive study with radiographic analysis of 50 adults aged between 30 to 70 years old. The group was divided into Group 1: without neck pain, and Group 2: with neck pain. All answered a questionnaire about age and the presence or absence of neck pain. Exclusion criteria were: inadequate X-Ray image, deformity or previous spine surgery, limited shoulder mobility, and individuals younger than 30 and older than 70. The radiographic parameters evaluated were: COBB, TIA ( THORACIC INLET ANGLE), T1 SLOPE, NECKTILT, and COG-C7 with no neck pain. α = 5% (significance when p <0.05). Results: The MANN WHITNEY nonparametric test showed no significant differences between Cobb GROUPS (p= 0.7452), T1 SLOPE GROUPS (p=0.1410), NECKTILT GROUPS (p=0.0852) and GROUPS THORACIC INLET ANGLE (p=0.1789). Conclusion: There was a significant difference only between COG-C7 GROUPS (cm) (p=0.0013). The analysis of the obtained data showed statistical significance in the variation in the COG-C7 groups. Level of Evidence II; Prospective comparative study.

Temporal trends and spatial clusters of gastric cancer mortality in Brazil / Tendencias temporales y conglomerados espaciales de mortalidad por cáncer gástrico en Brasil / Tendências temporais e aglomerados espaciais de mortalidade por câncer gástrico no Brasil

ABSTRACT Objective. To identify nationwide temporal trends and spatial patterns of gastric cancer-related mortality in Brazil. Methods. An ecological study was performed using death certificates registered from 2000 to 2019 in which gastric cancer was recorded as any cause of death (an underlying or associated cause). Trends over time were assessed using joinpoint regression models. Spatial and spatiotemporal clusters were identified by Kulldorff's space-time scan statistics to identify high-risk areas. Results. In 276 897/22 663 091 (1.22%) death certificates gastric cancer was recorded as any cause of death. Age-adjusted gastric cancer-related mortality increased significantly over time (annual percentage change [APC]: 0.7, 95% confidence interval [CI]: 0.5 to 0.8). The increase in mortality was more pronounced in the less-developed North and Northeast Regions (North Region, APC: 3.1, 95% CI: 2.7 to 3.5; Northeast Region, APC: 3.1, 95% CI: 2.5 to 3.7). Eight spatiotemporally associated high-risk clusters of gastric cancer-related mortality were identified in the North, South, Northeast and Central-West Regions, as well as a major cluster covering a wide geographical range in the South and Southeast Regions of Brazil during the first years of the study period (2000 to 2009). Conclusions. More recently, during 2010 to 2019, clusters of gastric cancer have been identified in the Northeast Region. The nationwide increase in mortality in this analysis of 20 years of data highlights the persistently high burden of gastric cancer in Brazil, especially in socioeconomically disadvantaged regions. The identification of these areas where the population is at high risk for gastric cancer-related mortality emphasizes the need to develop effective and intersectoral control measures.

RESUMEN Objetivo. Identificar las tendencias temporales y los patrones espaciales de la mortalidad relacionada con el cáncer gástrico a nivel nacional en Brasil. Métodos. Se realizó un estudio ecológico, empleando certificados de defunción registrados entre los años 2000 y 2019 en los que se notificó cáncer gástrico como cualquier causa de muerte (subyacente o asociada). Se evaluaron las tendencias con el transcurso del tiempo mediante modelos de regresión de punto de inflexión (joinpoint). Se identificaron los conglomerados espaciales y espaciotemporales mediante la técnica estadística de exploración espaciotemporal de Kulldorff para determinar cuáles eran las áreas de alto riesgo. Resultados. En 276 897 de 22 663 091 certificados de defunción (1,22%), se registró cáncer gástrico como cualquier causa de muerte. La mortalidad relacionada con el cáncer gástrico ajustada por edad aumentó significativamente con el tiempo (cambio porcentual anual: 0,7; intervalo de confianza [IC] del 95%: 0,5 a 0,8). El aumento de la mortalidad fue más acusado en la regiones Norte y Noreste, menos desarrolladas, (región Norte, cambio porcentual anual: 3,1, IC del 95%: 2,7 a 3,5; región Noreste, cambio porcentual anual: 3,1, IC del 95%: 2,5 a 3,7). Durante los primeros años del período de estudio (del 2000 al 2009), se identificaron ocho conglomerados de alto riesgo de mortalidad relacionada con el cáncer gástrico y con asociación espacial y temporal en las regiones Norte, Sur, Noreste y Centro-Oeste, así como un conglomerado importante que cubría un amplio rango geográfico en las regiones Sur y Sureste de Brasil. Conclusiones. Más recientemente, del 2010 al 2019, se han identificado conglomerados de cáncer gástrico en la región noreste. El aumento nacional de la mortalidad en este análisis de veinte años de datos destaca la carga persistentemente alta del cáncer gástrico en Brasil, especialmente en las regiones socioeconómicamente desfavorecidas. La identificación de estas áreas en que la población presenta un alto riesgo de mortalidad relacionada con el cáncer gástrico subraya la necesidad de elaborar medidas de control intersectoriales y efectivas.

RESUMO Objetivo. Identificar tendências temporais e padrões espaciais de mortalidade relacionada ao câncer gástrico em todo o Brasil. Métodos. Realizou-se um estudo ecológico a partir de declarações de óbito registradas de 2000 a 2019 em que o câncer gástrico foi indicado como qualquer causa de morte (causa básica ou associada). As tendências ao longo do tempo foram avaliadas a partir de modelos de regressão por pontos de inflexão (joinpoint). Os aglomerados espaciais e espaço-temporais foram identificados por estatística de varredura espaço-temporal de Kulldorff para detectar áreas de alto risco. Resultados. O câncer gástrico foi registrado como qualquer causa de morte em 276.897/22.663.091 (1,22%) declarações de óbito. A mortalidade relacionada ao câncer gástrico ajustada por idade aumentou significativamente ao longo do tempo [variação percentual anual (VPA): 0,7, intervalo de confiança (IC) de 95%: 0,5 a 0,8]. O aumento da mortalidade foi mais acentuado no Norte e Nordeste, regiões menos desenvolvidas (região Norte, VPA: 3,1, IC 95%: 2,7 a 3,5; região Nordeste, VPA: 3,1, IC 95%: 2,5 a 3,7). Identificaram-se oito aglomerados de alto risco de mortalidade relacionada ao câncer gástrico em associação espaço-temporal nas regiões Norte, Sul, Nordeste e Centro-Oeste, além de um grande aglomerado que abrangia uma larga faixa geográfica nas regiões Sul e Sudeste do Brasil durante os primeiros anos do período de estudo (2000 a 2009). Conclusões. Mais recentemente, no período de 2010 a 2019, identificaram-se aglomerados de câncer gástrico na região Nordeste. O aumento da mortalidade em todo o país nesta análise de dados relativos a 20 anos evidencia a persistência da alta carga de câncer gástrico no Brasil, sobretudo em regiões desfavorecidas do ponto de vista socioeconômico. A identificação dessas áreas em que a população corre alto risco de morte relacionada ao câncer gástrico enfatiza a necessidade de desenvolver medidas de controle efetivas e intersetoriais.

Abdomen agudo por torsión de masa anexial en tercer trimestre del embarazo, reporte de un caso y revisión de la literatura / Adnexal mass torsion as a cause of acute abdomen in the third trimester of pregnancy. Case report and review of the literature

Resumen INTRODUCCIÓN: Las masas anexiales en el embarazo son hallazgos fortuitos durante la gestación. Suelen diagnosticarse con la ecografía del primer trimestre. Su incidencia y curso clínico varían dependiendo de las semanas de embarazo. La complicación más común es la torsión con abdomen agudo. La incidencia de torsión va de 0.2 a 15%, con aumento durante el embarazo con masas de mayor tamaño. Son poco frecuentes durante el tercer trimestre del embarazo. Los cistoadenomas mucinosos son parte de los tumores epiteliales benignos más frecuentes del ovario; se consideran precursores de carcinomas mucinosos. CASO CLÍNICO: Paciente de 34 años, con antecedentes obstétricos de cuatro embarazos: dos partos y dos abortos, con 31 semanas de embarazo al ingreso al Hospital Universitario de la Samaritana de Colombia, justificado por un cuadro clínico de 18 horas de evolución consistente en: dolor abdominal intenso, tipo punzada, de predominio en la fosa iliaca y el flanco derechos. En la laparotomía se encontró un tumor ovárico con torsión, que se resecó. El estudio anatomopatológico reportó "tumor mucinoso de tipo endocervical con severos cambios por infarto". La evolución materno perinatal fue satisfactoria. CONCLUSIONES: El diagnóstico de torsión de masa anexial como causa de abdomen agudo en el tercer trimestre del embarazo es complejo pues requiere historia clínica, imágenes y estudios paraclínicos. El pronóstico materno-perinatal es bueno cuándo el tratamiento médico-quirúrgico es oportuno. Se requiere determinar el tipo de masa con estudios anatomopatológicos para continuar el tratamiento integral. El tumor mucinoso de ovario, tipo endocervical en masas torcidas de ovario, es raro.

Abstract BACKGROUND: Adnexal masses of pregnancy are incidental findings during pregnancy. They are usually diagnosed with first trimester ultrasound. Their incidence and clinical course vary depending on the weeks of pregnancy. The most common complication is torsion with acute abdomen. The incidence of torsion ranges from 0.2 to 15%, with an increase during pregnancy with larger masses. They are rare during the third trimester of pregnancy. Mucinous cystoadenomas are among the most frequent benign epithelial tumors of the ovary; they are considered precursors of mucinous carcinomas. CLINICAL CASE: 34-year-old female patient, with obstetric history of four pregnancies: two deliveries and two miscarriages, 31 weeks pregnant on admission to the Hospital Universitario de la Samaritana of Colombia, justified by a clinical picture of 18 hours of evolution consisting of: intense abdominal pain, stabbing type, predominantly in the right iliac fossa and flank. At laparotomy the torsion was found and resected. The anatomopathological study reported "mucinous tumor of endocervical type with severe infarction changes". Maternal perinatal evolution was satisfactory. CONCLUSIONS: The diagnosis of adnexal mass torsion as a cause of acute abdomen in the third trimester of pregnancy is complex as it requires clinical history, imaging and paraclinical studies. The maternal-perinatal prognosis is good when medical-surgical treatment is timely. It is necessary to determine the type of mass with anatomopathological studies to continue the integral treatment. Mucinous ovarian tumor, endocervical type in twisted ovarian masses, is rare.

Introducción: A partir de la aparición de la epidemia COVID-19 se conforma un equipo multidisciplinario en Santiago de Cuba con participación de varias instituciones y activado por el Consejo de defensa provincial. El análisis integrado epidemiológico, la gestión gubernamental y la respuesta social resultarían determinantes en el control de la enfermedad. Objetivos: Identificar posibles grupos de casos con COVID-19 en la provincia Santiago de Cuba y caracterizar su transmisión según variables epidemiológicas. Métodos: Se desarrolló un estudio ecológico, comparándose los clústeres de transmisión de COVID-19. Se resumieron variables de interés y se realizó análisis de redes sociales desde el punto de vista de las relaciones entre casos y contactos, así como análisis espacial. Resultados: Se identificaron cinco grupos espaciales de transmisión en los municipios, uno en Palma Soriano, uno en Contramaestre y tres en Santiago de Cuba. Los antecedentes patológicos personales (hipertensión y procesos respiratorios), el sexo femenino, los casos sintomáticos y el promedio de 22 a 27 contactos por cada confirmado fueron las variables más relevantes. Se identificó fuente de infección introducida en 51 por ciento (25/49). Además, se identificaron redes sociales complejas en la transmisión de la enfermedad. Conclusiones: La transmisión de COVID-19 en la provincia Santiago de Cuba mostró grupos de casos y contactos con redes sociales epidemiológicas características para cada municipio, así como el modo de transmisión de acuerdo a la fuente de infección, relaciones de familiaridad o cercanía social y la relación de distancia espacial entre contactos, aspectos que influyeron en las bajas tasas de incidencia de la enfermedad, con predominio en su forma sintomática, edades jóvenes y en mujeres(AU)

Introduction: From the onset of COVID-19 epidemic, a multidisciplinary team is formed in Santiago de Cuba with the participation of several institutions and activated by the Provincial Defense Council. Integrated epidemiological analysis, government management and social response would be decisive in controlling the disease. Objectives: To identify possible groups of COVID-19 cases in the Santiago de Cuba province and to describe the transmission according to epidemiological variables. Methods: An ecological study was carried out, comparing COVID-19 transmission clusters. Variables of interest were summarized and analysis of social contact networks was carried out from the point of view of the relationships between cases and contacts, as well as spatial analysis. Results: Five spatial transmission groups were identified in the municipalities, one in Palma Soriano, one in Contramaestre and three in Santiago de Cuba. The personal pathological antecedents (hypertension and respiratory processes), female sex, symptomatic cases and the average of 22 to 27 contacts for each confirmed were the most relevant variables. A source of introduced infection was identified in 51 percent (25/49). In addition, complex social networks were identified in the transmission of the disease. Conclusions: The transmission of COVID-19 in Santiago de Cuba province showed groups of cases and contacts with characteristic epidemiological social networks for each municipality, as well as the mode of transmission according to the source of infection, relationships of familiarity or social closeness and the relationship of spatial distance between contacts, which influenced on the low incidence rates of the disease, with predominance of symptomatic form, young ages and in women(AU)

Factors behind burnout increase in medical students. Are the criteria so important? / Fatores por trás do burnout crescente em estudantes de medicina. Os critérios são tão importantes?

Abstract: Introduction: Medical students' mental health has been a concern to the scientific community, especially as a result of the epidemic of mental comorbidities that have become commonplace among the various social groups in modern society. Objectives: To evaluate the prevalence of Burnout among first- to fourth- year medical students and compare different criteria to define the syndrome. Methods: A total of 511 students from three universities in Brazil answered validated instruments to assess burnout (The Maslach Burnout Inventory) and quality of life (WHOQOL-BREF), and a questionnaire prepared by the authors to assess sociodemographic data Results: There was a prevalence of 31.1% of three-dimensional burnout, 37% of two-dimensional burnout and 44,8% of one-dimensional burnout. There were worse levels of emotional exhaustion among students with two-dimensional burnout, compared to those with only one-dimensional criterion, and worse levels of depersonalization among students with three-dimensional burnout, compared to those with two-dimensional criterion only. The same assessed variables showed correlation with all three criteria. Considering the four domains of quality of life - psychological, physical, environment and social relationships, the psychological and physical domains were the ones that correlated the most to all three aspects of the three-dimensional criteria. Emotional exhaustion was the dimension with the strongest association with three of the four quality of life domains. Conclusions: We question whether the three-dimensional criterion should really be the gold standard to define Burnout.

Resumo: Introdução: A saúde mental dos estudantes de medicina tem sido uma preocupação para a comunidade científica, especialmente como resultado da epidemia de comorbidades mentais que se tornaram comuns entre os vários grupos sociais da sociedade moderna. Objetivos: Este estudo teve como objetivos avaliar a prevalência de burnout em estudantes do primeiro ao quarto ano de um curso de Medicina e comparar as diferentes classificações de critério diagnóstico da síndrome. Métodos: Um total de 511 estudantes de três universidades brasileiras responderam a dois instrumentos validados para avaliar burnout e qualidade de vida, e a um questionário elaborado pelos autores para avaliar dados sociodemográficos e hábitos. Resultados: Houve prevalência de 31,1% de burnout tridimensional, 37% de burnout bidimensional e 44,8% de burnout unidimensional. Constatou-se um maior nível de exaustão no grupo com burnout bidimensional, em comparação ao grupo unidimensional, e verificou-se um maior nível de cinismo naqueles com burnout tridimensional, em comparação ao bidimensional. As variáveis que apresentaram correlação com a síndrome foram as mesmas nos três critérios analisados. Os domínios psicológico e físico foram os mais afetados na qualidade de vida dos escolares com burnout. A exaustão emocional foi a dimensão que apresentou correlações mais fortes com três dos quatro domínios analisados no instrumento WHOQOL-BREF. Conclusão: Observaram-se prejuízos nas diversas áreas relacionadas à qualidade de vida dos alunos. Questionamos se o uso do Maslach Burnout Inventory, por meio da abordagem tridimensional, realmente é o critério ideal a ser utilizado na triagem do burnout.

Association of serum levels of secreted frizzled-related protein 5 and Wnt member 5a with glomerular filtration rate in patients with type 2 diabetes mellitus and chronic renal disease: a cross-sectional study

ABSTRACT BACKGROUND: Diabetic nephropathy is a common complication of chronic kidney disease (CKD). ­Inflammation in the kidneys is crucial for promoting development and progression of this complication. Wnt member 5a (Wnt5a) and secreted frizzled-related protein 5 (Sfrp5) are proinflammatory proteins associated with insulin resistance and chronic low-grade adipose tissue inflammation. OBJECTIVE: To determine the correlation between serum Sfrp5 and Wnt5a concentrations and glomerular filtration rate in patients with type 2 diabetes mellitus and CKD. DESIGN AND SETTING: Cross-sectional, comparative and observational study in the Department of Endocrinology, Civil Hospital, Culiacán, Sinaloa, Mexico. METHODS: Eighty individuals with chronic kidney disease were recruited. Their serum Sfrp5 and Wnt5a concentrations were quantified using the enzyme-linked immunosorbent assay (ELISA) test. The statistical analysis consisted of the Mann-Whitney U test for independent samples and Spearman correlation, with statistical significance of P < 0.05. RESULTS: Serum Sfrp5 concentration continually increased through the stages of CKD progression, whereas serum Wnt5a concentration presented its highest levels in stage 3 CKD. Negative correlations between estimated glomerular filtration rate (eGFR) and serum concentrations of Sfrp5 (r = -0434, P = 0.001) and Wnt5a (r = -0481, P = 0.001) were found. CONCLUSIONS: There were negative correlations between serum Sfrp5 and Wnt5a concentrations and eGFR at each stage of CKD, with higher levels in female patients. This phenomenon suggests that Sfrp5 and Wnt5a might be involved in development and evolution towards end-stage renal disease.

O Uso da Estratégia Gameficação na Educação Médica / The Use of Gamefication Strategy in Medical Education

RESUMO Introdução O ensino por meio de metodologia ativa vem ganhando cada vez mais destaque no cenário da educação médica, complementando, ou mesmo substituindo, o método de ensino tradicional. Diante disso, o sistema de gameficação, bem aceito por estudantes, inova, uma vez que o aprendizado se torna lúdico e participativo, contribuindo para a formação holística dos acadêmicos. Objetivos: Descrever a realização de uma gincana - composta por quatro fases e de caráter competitivo -, bem como comprovar a eficácia do método como uma forma inovadora de aprendizagem. Ao todo, 16 acadêmicos de Medicina participaram da gincana. Metodologia Caracteriza-se como um estudo de delineamento observacional transversal, com uso de metodologias quantitativas e qualitativas. O estudo é composto pela aplicação de um método de ensino e aprendizado baseado no processo de gameficação, com posterior aplicação de um questionário avaliativo aos alunos, para análise crítica. Resultados Foi observada satisfação dos alunos quanto à atividade, sendo unânime a afirmação de que a técnica utilizada facilita o aprendizado. Entre os integrantes, 87,5% preferiram a aplicação de práticas de metodologias ativas em detrimento das tradicionais, e 81,25% dos participantes apontaram a necessidade de integrar métodos com abordagens lúdicas às suas atividades curriculares. Por outro lado, 12,5% dos estudantes concordaram em que a atividade lúdica aplicada não contribui para o trabalho em equipe e 6,25% preferiram adesão às práticas de metodologia tradicional. Conclusão O método de gameficação desenvolve um ambiente propício ao aprendizado, com grande adesão dos estudantes. Percebe-se também a necessidade de mudança, apoiada pelos alunos, nas formas de ensino utilizadas na graduação, devendo-se buscar metodologias que abranjam o desenvolvimento de múltiplas competências e que possam usar a ludicidade como atrativo para o processo de aprendizado.

ABSTRACT Introduction Education through active methodology is increasingly gaining attention in the medical education scenario, complementing, or even replacing, the traditional teaching method. Bearing this in mind, the system of gamification, a well-accepted one among students, innovates, since the learning process becomes playful and participatory, contributing to the holistic formation of the students. Objectives To describe the accomplishment of a four-round, competitive championship, and to prove the effectiveness of the method as an innovative form of learning. In all, 16 medical students participated in the championship. Methods This was a cross-sectional, observational study, using quantitative and qualitative methodologies. The study consists of the application of a teaching and learning method based on the gamification process and the subsequent application of an evaluation questionnaire to the students for critical analysis. Results Student satisfaction with the activity was observed, with the unanimous assertion that the technique used facilitates learning. 87.5% of the members preferred the application of active methodologies over traditional ones. 81.25% of the participants asserted the need to integrate methods with playful approaches into their curricular activities. On the other hand, 12.5% of the students agreed that the applied leisure activity does not corroborate for teamwork and 6.25% preferred the traditional teaching methods. Conclusion It was demonstrated that the method of gamification develops a propitious environment for the learning process, with substantial student support. The requirement for change in the educational methods used in undergraduate training could also be perceived, as well as support for such changes among students, and hence the need to seek more and more methodologies that support the development of multiple competences and that can use playfulness as an incentive for the learning process.

Diferenciación genética de las poblaciones de Felis catus en los municipios de Restrepo y Darién del Valle del Cauca, Colombia / Genetic differentiation of Felis catus populations in the municipalities Restrepo and Darién of Valle del Cauca, Colombia

Los genes implicados en los rasgos del pelaje de los gatos son útiles para el análisis de la estructura genética que presentan sus poblaciones. El objetivo de este trabajo fue determinar si existe diferenciación genética entre las poblaciones de gato doméstico de los municipios de Restrepo y Darién, los cuales se encuentran separados por el "Lago Calima". Para esto se estimaron las frecuencias alélicas de diversos marcadores del pelaje y se determinó si estas poblaciones presentaban diferencias significativas en su estructura génica o si se encontraban en equilibrio Hardy­Weinberg, además, se realizó una comparación con otras poblaciones inventariadas en el Valle del Cauca. Posteriormente, se llevó a cabo un análisis de componentes principales (ACP-Biplot), para conocer la correlación entre las frecuencias alélicas y los aportes de cada una de ellas a la variabilidad. También se realizó una prueba de Mantel para estimar si existía correlación entre los índices de fijación (FST) y las distancias geográficas. La prueba de Mantel mostró que el gen Orange es el único que muestra una correlación positiva entre los índices de diferenciación FST y las distancias geográficas. La comparación de las poblaciones de interés con las del Valle del Cauca, evidenció que los genes que aportaron más a la variabilidad fueron Dilution (19,08%), Long hair (16,09%), Agouti (16,06%) e Inhibitor (14,04%). Sin embargo, se encontró que las poblaciones de Restrepo y Darién tienen perfiles genéticos similiares y se comportan como una sola según los valores del equilibrio Hardy-Weinberg y los FST. Debido a que no hay diferencias significativas entre las poblaciones estudiadas, se concluye que, aunque el Lago Calima sea una barrera geográfica, no tiene un efecto significativo en la diferenciación genética entre las poblaciones de gatos de Restrepo y Darién.

The genes involved in cat coat traits are useful for the analysis of genetic structure within a population. The objective of this paper was to determine if any genetic differences exist among domestic cat populations from the municipalities of Restrepo and Darien, which are separated by Calima Lake. To analyze population structure, we estimated allelic frequencies of several coat markers, tested for alignment with the Hardy-Weinberg equilibrium, and compared our populations of interest to others from the Valle del Cauca region. Subsequently, we performed a principal components analysis (PCA-Biplot) to determine the correlation between allelic frequencies and their contributions to variability. A Mantel test was also used to estimate possible correlation among differentiation indexes (FST) and geographic distances. We performed the Mantel test on the Orange gene and identified a positive correlation among differentiation indexes (FST) and geographical distances. After comparing our populations of interest to others in the Valle del Cauca, we observed that the genes with the greatest contribution to variability were Dilution (19,08%), Long hair (16,09%), Agouti (16,06%) and Inhibitor (14,04%). However, we also found that the Restrepo and Darien populations of interest had similar genetic profiles, and aligned with the Hardy-Weinberg equilibrium, and the FST. Due to the absence of significant differentiation between the populations studied, we conclude that Calima Lake does not have a significant effect on any differentiation between the cat populations of Restrepo and Darien.

Evaluation of the Accuracy of Conventional and Digital Methods of Obtaining Dental Impressions / Evaluación de la Exactitud de los Métodos Convencionales y Digitales de la Obtención de Impresiones Dentales

ABSTRACT: The aim of this study was to carry out a literature review on the accuracy of conventional and digital dental impression methods, as well as present the various three-dimensional intraoral scanning systems. A bibliographic search was carried out in PUBMED's main health database, in which works published between 2008 and 2018 were collected. Laboratory studies, case reports and systematic reviews were included, addressing topics that deal with conventional digital materials, impression and precision. Articles that did not evaluate impression materials, their behavior and techniques to obtain a good impression of oral structures were excluded. Through a review in the literature, obtained the following findings: the most critical stage in macking a dental prothesis is to take the dental impression. The conventional technique of impression consists of obtaining a negative copy of the intra-oral situation that will be poured into gypsum, obtaining a positive copy, on which the work will be carried out. Digital scanning systems were not superior to conventional moldings when comparing fidelity, accuracy and detail reproduction; in contrast, they were superior to conventional impression when considering clinical chair time, patient and operator preference, and patient comfort.

RESUMEN: El objetivo de este estudio consistió en realizar una revisión bibliográfica sobre la precisión de los métodos de moldeo dental convencionales y digitales, así como presentar los diversos sistemas de escaneo intraoral tridimensionales. Se realizó una búsqueda bibliográfica en la base de datos de salud principal de PUBMED en la cual se recopilaron trabajos publicados entre 2008 y 2018. Se incluyeron estudios de laboratorio, informes de casos y revisiones sistemáticas, abordando temas que tratan con materiales digitales convencionales, moldeo y precisión. Se excluyeron los artículos que no evaluaron los materiales de moldeo, su comportamiento y técnicas para obtener una buena impresión de las estructuras orales. A través de una revisión exhaustiva en la literatura, obtuvimos los siguientes hallazgos: el paso más crítico en la preparación de una pieza protésica es la impresión de la preparación. La técnica convencional de moldeo consiste en obtener una copia negativa de la situación intraoral que se verterá en el yeso, obteniendo una copia positiva, sobre la cual se realizará el trabajo. Resulta que los sistemas de escaneo digital no fueron superiores a las molduras convencionales al comparar la fidelidad, precisión y reproducción de detalles; en cambio, fueron superiores a las molduras convencionales al considerar el tiempo de trabajo clínico, la preferencia del paciente y del operador y la comodidad del paciente.

The use of negative pressure wound therapy in the treatment of infected wounds. Case studies / Aplicação da terapia por pressão negativa no tratamento de feridas infectadas. Estudo de casos

ABSTRACT OBJECTIVE: To evaluate the results and benefits obtained from the topical use of negative pressure wound therapy (NPWT) in patients with infected wounds. METHODS: This was a retrospective study of 20 patients (17 males and three females, mean age 42 years) with infected wounds treated using NPWT. The infected wounds were caused by trauma. The treatment system used was VAC.(r) (Vacuum Assisted Closure, KCI, San Antonio, United States) applied to the wound in continuous mode from 100 to 125 mmHg. The parameters related to the wounds (location, number of VAC changes, the size of the defects in the soft parts, and the evolution of the state of the wound), length of hospital stay, length of intravenous antibiotic therapy, and complications related to the use of this therapy were evaluated. RESULTS: The mean length of the hospital stay, use of NPWT, and antibacterial therapy were 41 days, 22.5 days, and 20 days respectively. The use of the VAC led to a mean reduction of 29% in the wound area (95.65-68.1 cm2; p < 0.05). Only one patient did not show any improvement in the final appearance of the wound with complete eradication of the infection. No complication directly caused by NPWT was observed. CONCLUSION: NPWT stimulates infection-free scar tissue formation in a short time, and is a quick and comfortable alternative to conventional infected wounds treatment methods.

RESUMO OBJETIVO: Avaliar os resultados e benefícios trazidos pela aplicação tópica da terapia por pressão negativa (TPN) em pacientes com feridas infectadas. MÉTODOS: Estudo retrospectivo de série de casos composta por 20 pacientes (17 homens e três mulheres e média de 42 anos) com feridas infectadas tratadas pela TPN. As feridas infectadas em sua maioria foram de causa traumática. O sistema de pressão a vácuo usado foi o VAC(r) (Vacuum Assisted Closure, KCI, San Antonio, Estados Unidos), aplicado à ferida em modo contínuo na ordem de 100 a 125 mmHg. Na casuística, os parâmetros relacionados à ferida (localização, quantidade de trocas do VAC, tamanhos dos defeitos de partes moles, evolução do grau da ferida), o tempo de internamento, o tempo de antibioticoterapia venosa e as complicações relacionadas ao uso da terapia foram avaliados. RESULTADOS: O tempo médio de internamento, uso da terapia a vácuo e antibioticoterapia foi, respectivamente, de 41, 22,5 e 20 dias. O uso do VAC promoveu uma redução média da área das feridas de 29% (95,65 cm2 para 68,1 cm2; p < 0,05). Apenas um paciente não obteve melhoria do aspecto final da ferida, com erradicação completa da infecção. Nenhuma complicação atribuída diretamente ao uso da TPN foi observada. CONCLUSÃO: A terapia por pressão negativa, por facilitar a formação de um tecido de cicatrização ausente de infecção local num curto intervalo de tempo, representa uma opção rápida e confortável aos métodos convencionais no tratamento de feridas infectadas.

CONTENIDOS DE PLOMO EN ACELGA COMÚN Beta vulgaris L, PRODUCIDA EN EL CONTEXTO DE LA AGRICULTURA URBANA (BOGOTÁ, COLOMBIA) / LEVELS OF LEAD IN COMMON CHARD Beta vulgaris L, PRODUCED IN THE CONTEXT OF URBAN AGRICULTURE (BOGOTÁ, COLOMBIA)

Dentro de las posibles formas de contaminación de las hortalizas con plomo se encuentran el suelo cultivado, el agua de riego y la atmósfera; esta última debido a la suspensión de las partículas resultantes de la combustión principalmente de hidrocarburos. Con el objetivo de lograr determinar la cantidad de plomo presente en Acelga común Beta vulgaris L. producida en el contexto de la agricultura urbana, se implementó una huerta con dicho sistema productivo en la ciudad, la cual se localiza en las coordenadas: Latitud 4°42'39,6036" y Longitud 74°5'46,6152", a menos de 500 metros de distancia de dos vías vehiculares principales de la ciudad de Bogotá. Previo a la siembra, se realizaron dos tipos de análisis: contenidos de plomo en suelo cultivado y en agua para riego, con la finalidad de obtener un diagnóstico preliminar sobre los contenidos de este metal pesado en estas dos posibles fuentes de contaminación. Las labores de sistema productivo relacionadas con prácticas culturales se realizaron de manera artesanal, por lo tanto no se realizó ningún tipo de fertilización y en el manejo de plagas no hubo intervención de ningún tipo de producto con la finalidad de evitar sesgos en el presente trabajo. Al momento de la cosecha, se muestreó al azar el 10% de la población total de plantas sembradas; esta muestra fue analizada por medio de espectrofotometría de absorción atómica según procedimiento del método oficial 968.08 de la AOAC, arrojando como resultado 0 ppm de plomo. Estos resultados permiten afirmar que la producción agrícola urbana es una alternativa que fomenta la seguridad alimentaria, no solo desde los aspectos de ingesta de macro y micronutrientes, sino también desde el punto de vista de calidad e inocuidad de los alimentos al no detectarse plomo en el tejido vegetal.

Cultivated soil, irrigation water and the atmosphere are among the possible forms of contamination with lead of vegetables, the latter due to suspension of the particles resulting from the combustion, mainly hydrocarbons. In order to be able to determine the levels of lead present in common Chard Beta vulgaris L. produced in the context of urban agriculture, a vegetable garden with this production system was implemented in the city, which is located at coordinates: Latitude 4°42'39.6036" and Longitude 74°5'46.6152", less than 500 meters away from two main vehicular roads in the city of Bogotá. Before sowing, two types of analysis were performed: lead content in cultivated soil and irrigation water, with the purpose of obtaining a preliminary diagnosis of the contents of this heavy metal in these two possible sources of contamination. The productive system work related to culture practices were made using traditional methods, therefore no fertilization was performed and there was no intervention of any type of product for pest management with the aim of avoiding bias in this study. At harvest time, 10% of the total of plants population planted was randomly selected; this sample was analyzed by atomic absorption spectrophotometry through the AOAC official method 968.08 yielding a result of 0 ppm of lead. These results allow the confirmation that urban farming is an alternative that promotes food security, not only from the intake of macro and micro nutrients aspect, but also from the of quality and food safety point of view, since for lead was not detect in the plant tissue.

Variante de una hernia de Amyand / Amyand´s hernia variant

La hernia de Amyand es una condición clínica poco frecuente, en la cual el apéndice cecal se encuentra dentro de un saco herniario asociado o no a un cuadro clínico de apendicitis aguda. La patogenia de la inflamación del apéndice cecal no se ha establecido con certeza; sin embargo, se ha relacionado con contracción muscular y con aumento de la presión intraabdominal. Las manifestaciones clínicas son similares a las de la apendicitis aguda. El diagnóstico preoperatorio es poco probable, debido a que los síntomas son inespecíficos y las ayudas diagnósticas pueden no ser conclusivas; por esta razón, en la mayoría de los casos el diagnóstico se hace durante el acto quirúrgico. El tratamiento es netamente quirúrgico

Amyand´s hernia is a rare clinical condition where the appendix is located within a hernial sac associated or not with acute appendicitis. Pathogenesis of the inflammatory process of the appendix has not been established; however, theories such as muscle contraction and increased intrabadominal pressure have been proposed. Clinical manifestations are similar to those of acute appendicitis. Preoperative diagnosis is unlikely, because signs and symptoms are nonspecific and diagnostic images could be non conclusive; for this reason the diagnosis in most cases is made intraoperatively. Surgical treatment is mandatory

Cirugía laparoscópica en un paciente con mielolipoma suprarrenal derecho / Laparoscopic surgery in a patient with right adrenal myelolipoma

Los mielolipomas suprarrenales son tumores benignos inusuales de crecimiento lento, compuestos por tejido adiposo maduro y células hematopoyéticas. Se presentan en adultos entre la quinta y la sexta década de la vida y usualmente miden entre 3 y 7 cm. El 70 % de los casos son asintomáticos y hacen parte de los denominados 'incidentalomas' de la glándula suprarrenal. El tratamiento puede ser conservador o quirúrgico, dependiendo de los síntomas, el tamaño de la masa y el crecimiento tumoral en estudios consecutivos de imágenes diagnósticas. La suprarrenalectomía laparoscópica es un procedimiento seguro, que tiene una recuperación rápida, no requiere instrumentos, dispositivos o fuentes de energía costosos, y estéticamente es superior a la técnica abierta. Se presenta el caso de un hombre de 63 años con antecedentes de hipertensión arterial sistémica, diabetes mellitus de tipo 2 e hiperlipidemia, quien presentó como hallazgo incidental en imágenes diagnósticas una masa suprarrenal derecha. El examen físico y los estudios paraclínicos descartaron que el tumor fuera funcional. Se practicó suprarrenalectomía derecha laparoscópica sin complicaciones y se diagnosticó un mielolipoma por histopatología.

Adrenal myelolipomas are rare slow-growing benign tumors composed of mature adipose tissue and hematopoietic cells. They most often occur in adults in the 5th-6th decade, and usually measure between 3 and 7 cm; 70% of cases are asymptomatic and are part of the so called incidentalomas of the adrenal gland. Treatment can be conservative or surgical, depending on the symptoms, the size of the mass and the growth of the tumor in consecutive imaging studies. We report a 63-year old man with history of systemic arterial hypertension, diabetes mellitus type 2 and hyperlipidemia. A right adrenal mass was reported as incidental finding in diagnostic imaging. Physical examination and paraclinical studies ruled out a functioning tumor. Right laparoscopic adrenalectomy was performed without complications and a myelolipoma was diagnosed by histopathology. Myelolipomas should be included in the differential diagnosis of the adrenal gland incidentalomas. Laparsocopic adrenalectomy is a safe procedure with rapid recovery, does not require special instruments or devices, and is cosmetically superior to the open technique.

EVALUACIÓN DE LA PRODUCCIÓN DE PAPA CRIOLLA Solanum phureja CLON PAISA EN CONTENEDORES DE POLIETILENO DE ALTA DENSIDAD BAJO EL MARCO DE AGRICULTURA URBANA / EVALUATION OF "PAPA CRIOLLA" Solanum phureja "CLONE PAISA" PRODUCTION IN HIGH DENSITY POLYETHYLENE CONTAINERS WITHIN THE FRAMEWROK OF URBAN AGRICULTURE

Con el fin de evaluar la producción de papa criolla Solanum phureja clon Paisa en el contexto urbano, se desarrolló una investigación pionera de tipo descriptiva en la cual se evaluaron las siguientes variables: incidencia de plagas, peso en fresco por contenedor, peso fresco total y peso por clasificación comercial. Se utilizaron contenedores de doble fondo de polietileno de alta densidad y técnicas agroecológicas de producción, de las cuales se destaca la fertilización utilizada con base en tres componentes: materia orgánica, minerales y microorganismos. A partir de los datos obtenidos se calculó media, mediana, moda, desviación estándar y se realizó un análisis de la dispersión por medio de cuartiles para el resumen de la información en cada una de las clasificaciones de la papa. También se analizó el rango intercuartílico y coeficientes de variación para establecer la normalidad en la distribución de los datos. Los resultados mostraron que la producción promedio de S. phureja en los contenedores fue de 528,36 g/planta, que al ser comparados con las medias de producción en Colombia y en el departamento de Cundinamarca, se convierten en una alternativa viable, que contribuye de forma directa con el fortalecimiento de la soberanía y seguridad alimentaria. Esta investigación resalta que la producción agroecológica de papa en contenedores bajo el marco de la agricultura urbana y diseñada desde el punto de vista agroecológico, no solo es una realidad para promover la suficiencia y soberanía y seguridad alimentaria por medio de la producción de alimentos saludables de forma autónoma por la comunidad, sino que además se constituye en una herramienta para los procesos de construcción del espacio urbano con beneficios socioculturales, ambientales y paisajísticos.

In order to evaluate the production of "papa criolla" Solanum phureja, Paisa clone in the urban context, a pioneer descriptive research was carried out in which the following variables were assessed: incidence of pests, fresh weight per container, total fresh weight and weight per trade classification. Fresh weight per container. High density polyethylene and ecological techniques double bottom containers were used in production, in which the fertilizer used was based on three components: organic matter, microorganisms and minerals was emphasized. From the data obtained the mean, median, mode, standard deviation and dispersion analysis were calculated by using quartiles for the summary of the information in each of the potato classifications. The interquartile range and coefficients of variation were also analyzed in order to establish normal data distribution. The results showed that the average production of S. phureja in containers was 528.36 g/plant, that, when compared to the media production in Colombia and in the Department of Cundinamarca, become a viable alternative which directly contributes to the strengthening of food security and sovereignty. This research highlights how agroecologic production of potato, in containers under the framework of urban agriculture and designed from an agroecology point of view, is not only a reality to promote food sufficiency, sovereignty and food security through the production of healthy food by the community in an autonomous way, but also becomes a tool in the construction processes of urban space with sociocultural, environmental and landscape benefits.

Snakebites as a largely neglected problem in the Brazilian Amazon: highlights of the epidemiological trends in the State of Amazonas

Envenoming snakebites are thought to be a particularly important threat to public health worldwide, especially in rural areas of tropical and subtropical countries. The true magnitude of the public health threat posed by snakebites is unknown, making it difficult for public health officials to optimize prevention and treatment. The objective of this work was to conduct a systematic review of the literature to gather data on snakebite epidemiology in the Amazon region and describe a case series of snakebites from epidemiological surveillance in the State of Amazonas (1974-2012). Only 11 articles regarding snakebites were found. In the State of Amazonas, information regarding incidents involving snakes is scarce. Historical trends show an increasing number of cases after the second half of the 1980s. Snakebites predominated among adults (20-39 years old; 38%), in the male gender (78.9%) and in those living in rural areas (85.6%). The predominant snake envenomation type was bothropic. The incidence reported by the epidemiological surveillance in the State of Amazonas, reaching up to 200 cases/100,000 inhabitants in some areas, is among the highest annual snakebite incidence rates of any region in the world. The majority of the cases were reported in the rainy season with a case-fatality rate of 0.6%. Snakebite envenomation is a great disease burden in the State of Amazonas, representing a challenge for future investigations, including approaches to estimating incidence under-notification and case-fatality rates as well as the factors related to severity and disabilities.

Sarcoma Pleomórfico Indiferenciado de Maxilar de Alto Grado: Diagnóstico, Tratamiento y Pronóstico / Undifferentiated Pleomorphic Sarcoma of the Maxillary: Diagnosis, Treatment and Prognosis

Los sarcomas son neoplasias poco vistas en el territorio maxilofacial, donde la baja frecuencia de casos y los cambios de nomenclatura, han dificultado su estudio. Una de las variables de este tipo de lesiones corresponde a un tumor conocido como sarcoma pleomórfico indiferenciado, del cual se sabe muy poco pues se describe una incidencia de 1:1.000.000. Corresponde a un tumor maligno con características clínicas e imagenológicas de crecimiento invasivo y destructivo; la confirmación diagnóstica se realiza por medio de una biopsia en base al estudio histológico e inmunohistoquímico. Aparece principalmente en el tracto nasosinusal y su manejo terapéutico se basa en la cirugía con amplios márgenes de seguridad y radioterapia o quimioterapia según corresponda. No presenta metástasis locales pero si a distancia con gran afinidad por el pulmón. Se reporta un caso de sarcoma pleomórfico indiferenciado de alto grado de maxilar diagnosticado en la Unidad de Patología Oral y Maxilofacial del Hospital las Higueras de Talcahuano durante el año 2014, que a diferencia de la mayoría de los casos reportados, producto de su extensión, fue tratado con radioterapia paliativa. Además, se realizó una revisión de la literatura disponible en diversas bases de datos con lo cual se obtuvo información de casos ya reportados. Actualmente resulta difícil producto de la baja cantidad de casos descritos poder hacer proyecciones en cuanto a su pronóstico o evolución, sin embargo hay consenso de que el manejo interdisciplinario, diagnóstico precoz y la confirmación de este por medio de exámenes complementarios son fundamentales para su adecuado tratamiento.

Sarcomas are neoplastic lesions rarely observed in the maxillofacial region. Due to the few cases reported and to changes in nomenclature of these tumors their study has been difficult. One of the variants of this kind of lesion corresponds to a tumor currently known as undifferentiated pleomorphic sarcoma, which there is scarce knowledge of. In fact the incidence described is about 1:1.000.000. This one corresponds to a malignant tumor with image and clinical features as invasive and destructive growth, the confirmation of diagnosis is carried out by performing biopsy based on histologic and immunohistochemical studies. They appear mostly in the nose and sinusal tract. Its therapeutic management is based on surgery with wide security margins and radio or chemotherapy when warranted. No local metastases but distant ones are found and highly affined with lungs. We report a case of an advanced undifferentiated pleomorphic sarcoma diagnosed at the Oral and maxillofacial pathology unit of Hospital Las Higueras in Talcahuano at 2014, which in spite of most of the reported cases in literature; because of the extent it was treated with palliative radiotherapy. Also has been made review of the available literature in different databases with which information of the reported cases was obtained. Nowadays, due to the low number of cases described it is difficult to establish projections in terms of prognosis or evolution. However, there is consensus that interdisciplinary management, early diagnosis and confirmation with complementary exams are essential for an appropriate treatment.

Corioamnionitis en biopsia por congelación de placentas en pacientes con riesgo de infección y su relación con morbimortalidad del recién nacido / Histological chorioamnionitis in placental biopsy by frozen section in patients at increased risk of infection and its association with neonatal morbidity and mortality

Se busca determinar si el diagnóstico de corioamnionitis en biopsia por congelación de placenta se relaciona con desenlace desfavorable en el recién nacido. Materiales y métodos: cohorte prospectiva de gestantes con alta sospecha de corioamnionitis a quienes se les practicó biopsia por congelación de cordón y membranas con estudio histopatológico usual, y se relacionó con la morbimortalidad del recién nacido. Resultados: en 23 placentas con sospecha de corioamnionitis se hizo estudio por congelación y parafina; cuatro fueron positivos en ambos y 19 negativos. Cinco desarrollaron sepsis temprana, todos con diagnóstico clínico de corioamnionitis en sus madres, de los cuales tres fueron positivos en ambos estudios microscópicos. Conclusiones: se evaluó la sepsis temprana y la mortalidad en hijos de madres con corioamnionitis diagnosticada mediante biopsias por congelación y parafina, evidenciando una adecuada relación. El diagnóstico por congelación fue preciso y temprano, posicionándose como una posible herramienta diagnóstica que permite un abordaje temprano tanto materno como del neonato con infección potencial, para así disminuir los desenlaces adversos con impacto en la morbimortalidad neonatal...

To determine if histological diagnosis of chorioamnionitis in placental biopsy by frozen section is associated with adverse neonatal outcome. Materials and Methods: prospective cohort study performed in pregnant women with high risk of developing chorioamnionitis associated with neonatal morbidity and mortality. A placental biopsy by frozen section of umbilical cord and membranes was conducted and processed by the usual techniques. Results: placental frozen and paraphin-fixed sections were conducted in 23 patients with clinical suspicion of chorioamnionitis; four were positive in both studies and 19 were negative. Five infants born to women with diagnosed chorioamnionitis developed early-onset sepsis, of which three were positive in both histological studies. Conclusions: early-onset sepsis and mortality was evaluated in neonates of mothers with chorioamnionitis diagnosed by frozen and paraphin-fixed sections, evidencing an adequate relationship. Diagnosis by frozen biopsy section was accurate and timely, and has become a diagnostic tool which allows an early approach both in mothers and infants with potential infection, to reduce adverse outcomes impacting neonatal morbidity and mortality...
