RESUMEN

OBJECTIVE: To identify which social determinants of health explain the gap in the remaining teeth between men and women. METHODS: A secondary analysis of data from the Chilean National Health Survey (CNHS) 2016-2017 was performed on the number of remaining teeth in adults. The explanatory variables were organized into structural and intermediate social determinants of health according to the WHO framework. The contribution of both groups and the contribution of each individual explanatory variable to the remaining teeth gap was estimated using the Blinder-Oaxaca decomposition analysis. RESULTS: The predicted average number of remaining teeth for men was 23.4 and 21.0 for women, thus a mean difference of 2.4 teeth. 49.8% of the inequality between men and women was due to the different distribution (endowments) of the predictors in the model. Among them, structural determinants of health, namely education level (15.8%) and employment status (17.8%), contributed the most. Intermediate determinants had no relevant contribution to explain the gap. CONCLUSIONS: Results revealed that the difference in the mean number of remaining teeth between men and women was mainly explained by two structural determinants: education level and employment status. The lack of explanatory power of intermediate determinants and the large explanatory power of structural determinants means that tackling oral health inequity in Chile requires strong political commitment. The role of intersectoral and intersectional public policies to address gender inequalities in oral health in Chile is discussed.

RESUMEN

BACKGROUND: Severe oral mucositis associated with cancer therapy is a frequent complication that may affect a patient's systemic condition, resulting in interruption and/or prolongation of cancer therapy. Dentoxol® is a medical solution in the form of a mouthwash that has been shown to result in statistically significant improvement in the prevention of severe oral mucositis. However, knowing the measures of the clinical significance of this therapy is important for accurate decision-making. AIM: To describe the clinical impact of Dentoxol® use in severe oral mucositis. METHODS: Clinical significance was measured using the results obtained in a randomized controlled clinical trial previously conducted by the same group of researchers. The measures of clinical significance evaluated were the absolute risk or incidence, relative risk, absolute risk reduction, relative risk reduction, number needed to treat, and odds ratio. RESULTS: The data obtained show that the impact of Dentoxol® on reducing the severity of oral mucositis has important clinical relevance. CONCLUSION: The results of this study justify the incorporation of Dentoxol® mouth rinse into clinical protocols as a complement to cancer therapy to prevent and/or treat oral mucositis secondary to radiotherapy.

RESUMEN

Resumen En México, el estudio de la autolesión cuenta con pocas investigaciones, y menos si se trata de estudios que conformen posibles modelos explicativos. Teniendo esto en cuenta, en el presente trabajo se planteó como objetivo conocer la relación de la autolesión con la depresión, la desregulación emocional y los estilos de afrontamiento, con el fin de generar un modelo explicativo de la problemática. El estudio se realizó a partir de un diseño cuantitativo, transversal y con alcance explicativo, y se contó con una muestra de 5835 adolescentes (M edad = 11-15 años) inscritos en 62 secundarias públicas del estado de Sonora. Se realizaron regresiones logísticas para el análisis de los datos, y como resultado se encontró que, para los estudiantes con autolesión severa (3.54 %), el modelo explica el 61 % de la varianza en los datos (R1 de Nagelkerke = .61) y clasifica correctamente al 84.1 % de los participantes; mientras que, en la autolesión leve (5.29 %), el modelo explica el 72 % de la varianza en los datos (R2 de Nagelkerke = .72) y clasifica correctamente al 88.2 % de los estudiantes. Asimismo, las dimensiones de depresión mostraron el mayor nivel explicativo (cognitiva-afectiva, somática) y correlaciones positivas con la desregulación emocional y el estilo de afrontamiento de evitación, así como correlaciones negativas con el estilo de afrontamiento de aproximación. Al final se discute respecto a la importancia de las variables independientes para futuras investigaciones, y sobre los resultados anómalos y otros datos de interés.

Abstract In Mexico, there is little research on the study of self-injury and even less on possible explanatory models. With this in mind, this study aimed to determine the relationship between self-injury and depression, emotional dysregulation, and coping styles, to generate an explanatory model of the problem. The study was carried out using a quantitative, cross-sectional, explanatory scope, design and a sample of 5835 adolescents (Mage = 11-15 years) enrolled in 62 public high schools in the state of Sonora. Logistic regressions were performed for data analysis, and as a result it was found that, for students with severe self-injury (3.54 %), the model explains 61 % of the variance in the data (Nagelkerke's R2 = .61) and correctly classifies 84.1 % of the participants; whereas, in mild self-injury (5.29 %), the model explains 72 % of the variance in the data (Nagelkerke's R2 = .72) and correctly classifies 88.2 % of the students. Likewise, the depression dimensions showed the highest explanatory level (cognitive-affective, somatic) and positive correlations with emotional dysregulation and avoidance coping style, as well as negative correlations with approach coping style. At the end, the importance of the independent variables for future research is discussed, as well as anomalous results and other data of interest.

ABSTRACT: Objective: Dental caries is the most prevalent disease in children. In Chile, it is unknown whether the oral health status in children population has improved after the implementation of preventive strategies and programs in the last decade. The objective was to determine the prevalence of 6-year-old children with no caries experience (ceod=0) in the country, its territorial distribution and trend in the period 2012 to 2019. Methodology: An ecological study was carried out using the dental care records of 1,020,920 6-year-old children in the Chilean Health Services. The trend over time was analyzed using a linear trend test for proportions. Results: The prevalence of 6-year-old children without caries experience increased 1.2 points per year between 2012 and 2019. The prevalence in the Arica and Iquique Health Services and in the three Health Services in the Valparaíso Region exceeds 40%. In the four Health Services in the Biobío Region and in the Chiloé Health Service it is less than 25%. Conclusions: The prevalence of 6-year-old children without caries experience has improved in the last decade and its territorial distribution presents great variability; however, it still remains low.

RESUMEN

BACKGROUND: Cervical cancer is a public health problem in Latin America. Radiotherapy plays a fundamental role both as definitive or adjuvant treatment. There are important intra and inter-country differences regarding access and availability of radiotherapy facilities in this region. The aim of a study was to standardize the basic clinical and technical criteria for the radiation treatment of patients with CC in Chile and provide a guide for Latin American Radiation Oncologists. MATERIALS AND METHODS: Forty-one expert radiation oncologists from the Chilean Radiation Oncology Society made a consensus using the Delphi methodology. RESULTS: There was a high degree of agreement for each of the recommendations. Those with the lowest percentage were related to the definition of the conformal 3D technique as the standard for definitive external radiotherapy (81%) and the criteria for extended nodal irradiation (85%). CONCLUSIONS: These recommendations present an updated guide for radiotherapy treatment of patients with cervical cancer for Latin America. Those should be implemented according to local resources of each institution.

RESUMEN

Abstract Objective: To determine the association between occupational ionizing radiation exposure in the cardiovascular catheterization laboratories staff and development of lens changes. Methods: A cross-sectional study was made. Participants were recruited at the XIII Colombian Conference of Interventional Cardiology and SOLACI conferences in Bogotá - Colombia 2017. Informed consent was obtained from all study participants. Demographics and clinical data were collected. Associated lens changes were determined according to the ionizing radiation exposure status. Results: A total of 89 subjects (178 eyes) participated in the study. In general, the mean age was 40 years old, ranging from 19 to 78 years old. Distribution according gender was 55.3% male and 44.7% female. 31 subjects (62 eyes) were deemed to have not occupational exposure to radiation and 58 subjects (116 eyes) with a history of occupational radiation exposure. Exposed eyes had twice risk for present subcapsular posterior lens opacity compared to non-exposed eyes. The subjects with older age and physician role were associated to the presence of lens opacity, with a p value 0.001 in both cases. Likewise, exposed subjects with any lens opacity had a high mean occupational lifetime, with a p 0.001. Conclusions: This study confirms a statistically significant increase in radiation-associated subcapsular lens changes in the eyes of interventional cardiology staff compared to unexposed controls.

Resumen Objetivo: Determinar la asociación entre la exposición a radiación ionizante en el personal de las salas de cateterismo cardiovascular y el desarrollo de cambios en el cristalino. Métodos: Se hizo un estudio transversal. Los participantes fueron reclutados en el XIII Congreso Colombiano de Cardiología Intervencionista y las Conferencias SOLACI en Bogotá - Colombia 2017. Se obtuvo el consentimiento informado de todos los participantes. Se recolectaron datos demográficos y clínicos. Se determinó la asociación entre los cambios en el cristalino y la exposición a la radiación ionizante. Resultados: Un total de 89 sujetos (178 ojos) participaron en el estudio. En general, la edad promedio fue de 40 años, con edades comprendidas entre los 19 años y 78 años. La distribución según el género fue del 55,3% en hombres y el 44,7% en mujeres. Se consideró que 31 sujetos (62 ojos) no tenían exposición ocupacional a la radiación y 58 sujetos (116 ojos) presentaban exposición ocupacional a esta. Los ojos expuestos tenían dos veces el riesgo de presentar opacidad subcapsular posterior del cristalino en comparación con los ojos no expuestos. Los sujetos de mayor edad y con rol de médico se asociaron a la presencia de opacidad del cristalino, con un valor p de 0.001 en ambos casos. Del mismo modo, los sujetos expuestos con cualquier opacidad del cristalino tenían una vida laboral más larga, con una p 0.001. Conclusiones: Este estudio confirma un aumento estadísticamente significativo en la presencia de cambios en el cristalino en el personal de las salas de cateterismo cardiovascular en comparación con los controles no expuestos.

RESUMEN

ABSTRACT Objective. Isolate, identify and molecularly characterize pathogenic Cryptococcus isolates for humans from environmental and clinical samples from the city of Cúcuta. Materials and methods. A total of 1300 samples were collected from 446 trees of 10 different species in 10 public areas of Cúcuta. Concomitantly, clinical isolates of Cryptococcus neoformans were obtained (June 2016-June 2017). The samples were cultivated in Guizottia abysinica seed medium and were then biochemically identified and characterized by PCR fingerpinting and RFLP of the URA5 gene. Results. C. neoformans displayed an environmental prevalence of 4.3% (19 positive individuals), and that of C. gattii was 0.2% (1 positive individual); this yielded a total of 20 Cryptococcus-positive trees and 21 isolates (two from the same individual). Santander Park registered 47.6% of the global prevalence (10/21 isolates), followed by La Victoria Park with 23.8% (5/21 isolates), corresponding to C. neoformans. One C. gattii isolate was collected from a Ficus benjamina tree located in Mercedes Ábrego Park. Genotypic analysis revealed the presence of C. neoformans var. grubii VNI in 85.7% of environmental isolates as well as 100% of clinical isolates. VNII and VGII molecular types represented 9.5% and 4.8% of the environmental isolates, respectively. Conclusions. The longitudinal sampling of previously reported environmental niches of the fungus reveals its presence and suggests that permanent monitoring is required both in the environment and in patients, especially in endemic areas of the city.

Resumen Objetivo. Determinar el valor explicativo de los recursos de ajuste psicosocial sobre la satisfacción con la vida, en un grupo de estudiantes egresados de bachillerato. Método. La muestra se seleccionó de un total de 117271 jóvenes que egresaron en 2016 de la educación media superior en los municipios de Navojoa, Hermosillo y Ciudad Obregón, en México. La muestra final estuvo conformada por 2237 participantes, quienes respondieron a cuatro medidas de ajuste psicosocial (autoconcepto, locus de control, afrontamiento y orientación al éxito) y un cuestionario de satisfacción con la vida. Para el análisis de los datos se realizó un modelo de regresión lineal. Resultados. Se encontró que el modelo de regresión final sugiere que el autoconcepto positivo (P = 0.62) y el afrontamiento positivo (P = 0.14) predicen la satisfacción con la vida en los jóvenes egresados de la educación media (R 2 = 0.63). Conclusión. Se observó que el autoconcepto es la variable de mayor determinación sobre la satisfacción con la vida de estos jóvenes, de ahí que su ajuste se relacione fundamentalmente con el autoconcepto, el locus de control y las formas de enfrentar los problemas, variables que deberían considerarse al momento de promover una transición adecuada del bachiller a la educación superior.

Abstract Objective. The present study objective is to determine the explanatory value of psychosocial adjustment resources on life satisfaction in a group of high school graduates. Method. The sample was selected from a total of 117271 young people, who in 2016, graduated from upper secondary education in the municipalities of Navojoa, Hermosillo and Ciudad Obregón, in Mexico. The final sample consisted of 2237 participants, who responded to four measures of psychosocial adjustment (self-concept, locus of control, coping and orientation to success) and a questionnaire of life satisfaction. For the data analysis, a linear regression model was performed. Results. The final regression model suggests that the positive self-concept (P = 0.62) and positive coping (P = 0.14) predict life satisfaction in the high school graduates (R2 = 0.63). Conclusion. The self-concept is the variable with the greatest determination about life satisfaction in the sample. On the other hand, the adjustment profile of adolescents fundamentally depends on their self-concept, their locus of control and their ways of facing the problems, which should be considered in order to promote an adequate transition from high school to higher education.

RESUMEN

RESUMEN: Objetivo: Creación de un currículo de competencias mínimas en Cariología, para la formación de los Cirujano-Dentistas egresados de las escuelas de Odontología de Chile. Metodologías: A partir de una reunión de académicos de las Universidades de Talca y de Chile (año 2011), se elaboró una propuesta de currículo inicial, basado en los dominios propuestos por la Unión Europea (Schulte AG y cols). Durante el año 2016, dicha propuesta fue analizada mediante diálogos digitales y grupos de trabajo, con la participación del 96% de las Escuelas de Odontología existentes en el país, que concluyeron en un documento intermedio. Este documento fue analizado, discutido y perfeccionado durante el Taller para el Desarrollo de un Currículo de Competencias Mínimas en Cariología para las Escuelas de Odontología Chilenas (22/Mayo/2017, Talca, organizado por la Universidad de Talca y la Universidad de Chile) con la asistencia de representantes del 96% de las escuelas dentales chilenas, Ministerio de Salud de Chile, Colegio de Cirujano-Dentistas de Chile y con la asesoría de los profesores de Cariología Dres. Margherita Fontana y Carlos González-Cabezas (Universidad de Michigan, Ann Arbor, EEUU). Cada grupo de trabajo revisó el documento y envió nuevos comentarios, los que fueron incorporados en el documento final por una comisión asesora. Resultados: El documento del Currículo en Cariología se organizó en 5 Dominios: 1. Conocimientos base; 2. Determinación de Riesgo, diagnóstico de caries y detección de lesiones de caries; 3. Toma de decisiones y manejo preventivo no operatorio; 4. Toma de decisiones y manejo operatorio y 5. Cariología basada en la evidencia, en la práctica clínica y de salud pública. Se consensuaron las definiciones operacionales, las competencias principales y las sub-competencias para cada uno de los dominios. Las sub-competencias fueron clasificadas en tres niveles: A: Ser competente en; B: Tener conocimientos sobre y C: Estar familiarizado con. El documento final fue enviado a todos los participantes del taller para su aprobación y difusión en cada una de las instituciones involucradas. Conclusiones: Se logró, por medio de consenso, la construcción del Currículo de Competencias mínimas en Cariología para estudiantes de pregrado de Odontología en las universidades chilenas.

ABSTRACT: Objective: Development of a minimum set of competencies in Cariology that every dentist graduated from a Dental School in Chile must have. Methodology: Starting from a meeting of scholars from the Universities of Talca and Chile (year 2011), an initial proposal for a curriculum was developed, based on the domains proposed by the European Cariology Curriculum (Schulte, et al, 2011). During 2016, this proposal was discussed through online dialogues and working groups, with the participation of 95.2% of the Chilean dental schools, which resulted in an intermediate document. This document was analyzed, discussed and refined during the Workshop for the Development of a Curriculum of Minimum Competencies in Cariology for Chilean Dental Schools (May 22, 2017, Talca, organized by the Universities of Talca and Chile) with the attendance of representatives from 95.2% of the Chilean dental schools, the Chilean Ministry of Health, Chilean College od Dentists and with the assistance of the professors of Cariology Margherita Fontana and Carlos González-Cabezas (University of Michigan, Ann Arbor, USA). Each working group revised the document and provided feedback, which was incorporated in the final document by an advisory committee, elected on the day of the workshop, including the authors of the present article. Results: The Cariology Curriculum was organized in 5 Domains: 1. Basic knowledge; 2. Risk assessment, caries diagnosis and caries lesion detection; 3. Decision-making and non-operative preventive treatment; 4. Decision making and operative treatment; and 5. Evidence-based, clinical and public health practice. Operational definitions, main competencies and sub-competencies for each domain were agreed. Sub-competencies were classified into three levels: A: Be competent in; B: Have knowledge about, and C: Be familiar with. The final document was sent to all the participants of the workshop for dissemination in each of the institutions involved. Conclusions: The development of the Competency-based Curriculum in Cariology for undergraduate dental students at Chilean universities was achieved through consensus.

RESUMEN

BACKGROUND: Obesity and its consequences have now reached worldwide pandemic proportions. Among treatments, bariatric interventions are the most effective for weight reduction. Here, we describe the change in anthropometric measurements (AMs) of 615 adult bariatric procedure patients seen in the private practice of a registered dietitian (RD) in Bogotá, Colombia. METHODS: Observational retrospective study of AMs recorded between 1996 and 2013 for patients who had laparoscopic sleeve gastrectomy (LSG, n = 290), laparoscopic adjustable gastric banding (LAGB, n = 207), and laparoscopic Roux-EN-Y gastric bypass (LRYGB, n = 36) or the non-surgical gastric balloon (GB, n = 82) procedure. Patients had three bimonthly follow-up visits. Paired t tests compared baseline (first) and 6-month (fourth) follow-up visit values. RESULTS: Differences in AMs between the baseline and fourth visits were statistically significant for the surgical interventions. A mean weight loss of 22 kg, equivalent to a 22% total body weight loss, together with significant reduction of the waist-to-height-ratio (WHtR)(p < 0.001) and body mass index (BMI)(p < 0.001), was observed across all procedures. CONCLUSIONS: The use of multiple AMs enables a comprehensive assessment of body composition in patients who undergo bariatric procedures. Our study is a useful resource for international future reference and highlights the impact that the RD can have on understanding and influencing the effectiveness of bariatric procedures.

RESUMEN

BACKGROUND: The high recurrence rate following keloid resection has generated interest in adjuvant treatments for this disease. OBJECTIVE: This study assesses keloid recurrence when treated with surgery and adjuvant radiotherapy. METHODS: Retrospective analysis of resected keloids in patients referred to a Chilean radiation oncology centre between 2006 and 2013. Local recurrence was defined as new tissue growth on the surgical scar margin. RESULTS: Around103 keloids were analysed in 63 patients treated with 15 Gy in three fraction radiotherapy which was initiated on the same day as the surgery (75% of cases). The median keloid diameter was 6 cm; the most common site was thoracic (22%); the most common cause was prior surgery (35%); 37% caused symptoms, and several (47%) had received prior treatment with corticosteroids (32%), or surgery (30%). The median follow-up was three years, and 94% of recurrences occurred during the first year following treatment. Uni and multivariate analyses showed that an absence of symptoms was a protective factor for recurrence (OR: 0.24), while the time interval from onset to treatment with surgery plus radiotherapy >4.2 years was a risk factor (OR: 2.23). The first year recurrence rate was 32% and stabilised at 32% by the second year with no recurrences after 15 months. CONCLUSIONS: The combination of surgery and radiotherapy proved to be a good therapeutic alternative in the management of keloids. Our results are similar to those described in the literature for a dose of 15 Gy. Given these results, our centre will implement a new dose escalation protocol to improve future outcomes.

RESUMEN

En este estudio los materiales fueron seleccionados en 53 fincas pertenecientes a cuatro asociaciones de cultivadores de mora en los municipios de Pamplona y Chitagá (Norte de Santander, Colombia). Se emplearon como explantes segmentos nodales, los cuales permitieron obtener en poco tiempo brotes adventicios adecuados para la multiplicación masiva. Para la etapa de establecimiento se empleó el medio de cultivo Murashige y Skoog, (MS 1962), suplementado con ácido giberélico (GA3) (0.0-0.1 mg/L) y 6-benzil aminopurina (BAP) (0,0-2,0 mg/L), en la etapa de multiplicación MS ,suplementado con GA3 (0,0-0,03 mg/L-1) y BAP (0,0-2,5 mg/L) y para la etapa de enraizamiento MS, suplementados con ácido indolbutírico (AIB) (0,0-1,0 mg/L). A los datos generados en las tres etapas, se les aplicó un diseño experimental de bloques completos al azar y se analizaron estadísticamente los promedios de los tratamientos mediante una prueba de Tukey. Los resultados alcanzados indicaron tasas promedio de contaminación (16,5-49,7 %) multiplicación (3,8-4,3 brotes/explante) y enraizamiento (3,3-4,3 raíces/planta) in vitro para los diferentes materiales seleccionados y evaluados. Estos resultados, logrados por primera vez en la región Nororiental de Colombia, son importantes por cuanto se contara con materiales seleccionados disponibles para los cultivadores de mora de la región.

In this study plant materials were selected in 53 farms belonging to four growers associations of blackberry in the municipalities of Pamplona and Chitagá (North of de Santander, Colombia). Nodal segments were used as initial explants of R. glaucus. For the establishment stage Murashige and Skoog, 1962 (MS) media was used and, supplemented with of gibberellic acid (GA3) (0.0 -0.1 mg/L) and 6-aminopurine (BAP) (0.0 -2.0 mg/L); for the multiplication stage MS was supplemented with GA3 (0.0 -0.03 mg/L) and BAP, (0.0 -2.5 mg/L) and for the rooting stage MS was supplemented with acid indolbutirico (0.0 -1.0 mg/L). From the data generated during the three stages, an experimental design of incomplete blocks was randomly applied and the treatments averages were statistically analyzed using the Tukey Test. The results indicated average rates of contamination (16.5-49.7 %), multiplication (3.8-4.3 shoots/explant) and in vitro rooting (3.3-4.3 roots/plant) for the different evaluated materials. These results, achieved first in the Northeastern region of Colombia, are important in that they will feature selected materials available for blackberry growers in the region.

RESUMEN

Se llevó a cabo un estudio sobre bienestar subjetivo en estudiantes de una universidad privada en Hermosillo, Sonora, México. Se estudió la relación de los constructos "satisfacción con la vida" y "afectos positivos", en una muestra de 371 alumnos mediante la Encuesta Internacional para Alumnos Universitarios (Diener, 2001). Los resultados muestran que en el grupo de los más satisfechos la dimensión "satisfacción con la vida" se correlaciona significativamente con la percepción de la felicidad, mientras la dimensión "afectos positivos" se correlaciona con socialización de las emociones. La edad contrasta significativamente con los niveles de satisfacción con la vida: a menor edad, mayor es la satisfacción. Además, los que estudian una ingeniería o una carrera del área administrativa resultan con los puntajes más elevados, dato contrario con jóvenes de universidades públicas, donde estudiantes que pertenecen a las ciencias sociales y humanidades son las áreas que resultan más satisfechos con la vida.

Realizou-se uma pesquisa sobre o bem-estar subjetivo de estudantes de uma universidade privada de Hermosillo, Sonora, México. Foi estudada a relação entre os construtos "satisfação com a vida" e "afetos positivos", numa amostra de 371 alunos, por meio da Escala Internacional para Alunos Universitários. Os resultados mostram que, no grupo dos mais satisfeitos, a dimensão "satisfação com a vida" correlaciona-se significativamente com a percepção da felicidade, enquanto a dimensão "afetos positivos" correlaciona-se com socialização das emoções. Entre idade e níveis de satisfação com a vida, há uma relação significativa e inversa: quanto menor a idade, maior a satisfação. Além disso, os estudantes das áreas de engenharia e administração apresentam resultados mais elevados, dado diferente do encontrado entre jovens de universidades públicas, entre os quais as ciências sociais e as humanidades são as áreas de mais satisfação com a vida.

A study about the subjective well-being of students from a private university was carried out in Hermosillo, Sonora, Mexico. The relationship between "life satisfaction" and "positive feelings" was studied in a sample of 371 students by means of the International Survey for University Students (Diener, 2001). The results show that the "life satisfaction" factor is highly related to the perception of happiness in the most satisfied group, whereas the "positive feelings" factor is related to the socialization of emotions. Age is related to the levels of life satisfaction: a reverse relationship between age and satisfaction. In addition, it was established that the areas which the subjects study are related to the level of satisfaction. Those who study engineering or administration came out with the highest scores. In contrast, subjects from public universities who study social sciences and humanities turn out more satisfied with life.

RESUMEN

La superposición cefalométrica es una herramienta indispensable en la práctica de la Ortodoncia ya que permite evaluar los cambios que sufre el complejo craneofacial a través del proceso de crecimiento y desarrollo o aquellos cambios logrados mediante un tratamiento. En la literatura se han descrito múltiples técnicas de superposición cefalométrica; la mayoría de ellas utilizan como puntos de referencia zonas anatómicas poco estables durante el periodo de crecimiento y desarrollo. El doctor Björk describió una técnica de superposición cefalométrica basada en estudios con implantes metálicos, lo cual permitió identificar puntos de referencia y zonas anatómicas mas estables durante este periodo, por lo que permite medir y valorar los cambios craneofaciales de una manera mas confiable. El Objetivo de este articulo es describir la técnica de superposición estructural de Björk para su utilización como herramienta en la practica clínica e investigativa de la Ortodoncia.

Cephalometric superimposition is a critical tool in Orthodontics when evaluating changes affecting the craniofacial complex through the process of growth and development, or those obtained with treatment. Several cephalometric superimposition techniques have been reported previously, but most of them use unstable anatomical landmarks as reference areas or points to establish changes during growth and development. Björk's method describes a cephalometric superimposition technique based on studies with metal implants which allowed to identify stable reference points during the growth and therefore enable the possibility of measuring and evaluating craniofacial changes in amore reliable manner. The objective of this article is to describe Björk structural superimposition method as a tool in clinical practice and research in Orthodontics.

RESUMEN

La cirugía bariátrica es un procedimiento exitoso y cada vez más utilizado para el tratamiento de la obesidad con presencia de enfermedades asociadas o sin ella. Existen diferentes tipos de procedimientos los cuales se seleccionan dependiendo del tipo de paciente y de la recomendación y experiencia del médico tratante. La cirugía bariátrica per se genera deficiencias nutricionales que deben considerarse de antemano y, por lo tanto, ser tratadas y no obviadas. La administración a ciegas de suplementos nutricionales conlleva a pecar tanto por déficit como por exceso, lo cual genera consecuencias nutricionales a corto y a largo plazo. El cirujano y su equipo deben ir más allá del procedimiento quirúrgico y contribuir con el tratamiento metabólico y nutricional, consiguiendo una mejor calidad de vida para el paciente.

Bariatric surgery is a successful procedure increasingly used for the treatment of obesity with or without the presence of comorbidities. There are several bariatric procedures, which are selected depending on the patient, the recommendation and experience of the physician. Bariatric surgery "per se" generates nutritional deficiencies that must be considered in advance and therefore treated and not obviated. The blind administration of nutritional supplements leads to both deficit and excess, creating short and long term nutritional consequences. The surgeon and his team must go beyond the surgical procedure and consider nutrition as a complementary treatment, which contributes to a better metabolic and nutritional patient's status and therefore a better quality of life.

RESUMEN

La cirugía bariátrica es hasta el momento la mejor solución para el problema de obesidad y la diabetes, e incluso, influye en la mejoría de las enfermedades no transmisibles relacionadas con la nutrición. Sin embargo, no está exenta de complicaciones, entre las cuales son frecuentes las metabólicas y nutricionales que, afortunadamente, son predecibles, prevenibles y tratables. Es necesario que el médico, el equipo de salud y el paciente se encuentren conscientes de la importancia de la nutrición, no solamente antes de la cirugía e inmediatamente después de ella, sino el resto de la vida. Es fundamental cumplir diariamente con las necesidades de proteína del paciente, la cual debe seleccionarse en la forma más tolerable y absorbible, con el objeto de prevenir deficiencias nutricionales importantes que muchas veces se atribuyen equivocadamente a déficits de otros nutrientes. Finalmente, el cambio de estilo de vida debe incorporarse al tratamiento, para prevenir de esta manera la nueva ganancia de peso y las implicaciones que esto conlleva.

Up to now, bariatric surgery has been the prime solution for obesity and diabetes, and even positively contributes to nutrition related non-transmissible diseases. However, bariatric surgery is not exempt from complications, most of which are metabolic or nutritionally related. Fortunately, these complications are preventable, predictable and treatable. It becomes necessary for the physician, patient and health team to be to be conscious not only of the importance of the needs not only before surgery and immediately following it, but in the context of the patient´s life span. It is fundamental to fulfill the patient's daily protein requirements by adhering to a protein diet that is both tolerable and absorbable in order to prevent important protein nutritional deficiencies, which sometimes are wrongly attributed to deficiencies of other nutrients. Finally, the patient´s change in life style must be incorporated in the treatment program so as to prevent new weight gain and its related effects.

RESUMEN

Objetivo. Reconocer las especies cultivadas y silvestres de Rubus en 53 fincas con cultivos comerciales de Rubus glaucus Benth, pertenecientes a cuatro asociaciones de cultivadores de mora en los municipios de Pamplona y Chitagá (Norte de Santander, Colombia). Materiales y métodos. Se recolectaron 3-5 especímenes en cada uno de los predios de los agricultores y en los bordes de los caminos. Para la especie cultivada se seleccionaron plantas con edades entre 9-12 meses de establecidas en las parcelas comerciales y material silvestre con características típicas de Rubus. Se evaluaron veinte y dos descriptores (catorce cuantitativos y ocho cualitativos), considerándose los ubicados entre la séptima y octava yema de las ramas hembras y machos (cinco repeticiones), frutos y flores de cada material. A las catorce variables cuantitativas se les realizó el análisis de componentes principales, para identificar los descriptores que más contribuían con la diferenciación morfológica entre las accesiones analizadas. Se efectuó un análisis de conglomerados que permitió agrupar las diferentes accesiones por su semejanza o disimilitud. El algoritmo utilizado fue el método de Ward. Resultados. De las 147 accesiones analizadas, el estudio permitió reconocer la presencia de seis taxa diferentes R. glaucus Benth (con espinas y sin espinas), R. alpinus Macfad, R. adenotrichos Schltdl, R. rosifolius Sm., R. bogotensis Kunth y R. floribundus Kunth. Conclusiones. Los descriptores que permitieron diferenciar las especies y discriminarlas por grupos y aportan el 77% de la información en el estudio, mediante el análisis de componentes principales fueron: el largo y el ancho de los foliolos tanto laterales como centrales, la longitud de estructuras florales y foliares, la forma del ápice, y el número de venas secundarias...

Phenotypical characterization of Rubus L. species accessions in the provinces of Pamplona and Chitagá, northeastern region of Colombia. Objective. Determine the cultivated and wild species of Rubus in 53 commercial farms of Rubus glaucus Benth, owned by four blackberry growers association in the provinces of Pamplona and Chitagá (North of Santander, Colombia). Materials and methods. Three to five specimens were collected from each farm and along the roadside. Plants aged 9 to 12 months established in the commercial farms and wild materials with characteristics of Rubus were selected. Twenty two descriptors (fourteen quantitative and eight qualitative) were assessed. We considered the seventh and eighth branch buds both male and female (with five repetitions) and fruits and flowers of each material. Principal component analysis was done with the fourteen quantitative variables, to identify the descriptors that most contribute to the morphological differentiation of accessions. A conglomerate analysis was used for grouping accessions according to their similarity and dissimilarity. Results. Among the 147 accessions analyzed from the different farms, our study determined the presence of 6 different taxa: R. glaucus Benth (with and without spines), R. alpinus Macfad, R. adenotrichos Schltdl, R. rosifolius Sm., R. bogotensis Kunth and R. floribundus Kunth Conclusions. The descriptors that differentiated the species and discriminated them by groups by providing 77% of the information with the use of principal component analysis, were: length and width of central and lateral leaflets, length of flower and leaf structures, apex shape and number of secondary veins...

RESUMEN

OBJECTIVES: The association between aortic stenosis (AS) and acquired von Willebrand disease type 2A has been described. It may be present in up to 90% of patients with AS. Shear stress has been proposed as the underlying mechanism; however, the physiopathology of this condition is not completely understood. No specific treatment has been studied in this specific population besides aortic valve replacement (AVR). As a coadjuvant therapy, some cardiac surgery centers use desmopressin routinely. The authors report the first stage of an ongoing study designed to compare the effects of desmopressin versus placebo in patients with severe AS scheduled for AVR. Because of the different incidences of the acquired von Willebrand type 2A reported in the literature, the first stage was conducted to describe the incidence of this clinical association in the present population, allowing the sample size for the second stage of the study to be obtained. DESIGN: A prospective cohort study. SETTING: A single academic medical center. PARTICIPANTS: Thirteen patients with severe AS scheduled for AVR. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Patients with severe AS scheduled for AVR were studied preoperatively with a von Willebrand laboratory panel. Results were negative for acquired von Willebrand disease type 2A in all patients. The second stage of the trial was stopped. CONCLUSION: Contrary to previous reports, no correlation was found between AS and acquired von Willebrand disease type 2A. Further studies are needed to ascertain whether this lack of association is caused by a specific characteristic of the present population, the small sample size, or other factors.
