- ÍtemAcceso Abierto004 - A Novel Familial Case of Diffuse Leukodystrophy Related to NDUFV1 Compound Heterozygous Mutations(2013-07-30) Rivera-Nieto, C.; Mateus, H.; Ortega-Recalde, O.; Fonseca Mendoza, Dora Janeth; Patiño, L.; Restrepo Fernández, Carlos Martín; Van der Knaap, M.; Laissue, P.Introduction: Mitochondrial leukodystrophy due to complex I deficiency is an entity with high genetic heterogeneity, the mutations of the gene NDUFV1 being one of the causes of this disease. It is an autosomal recessive entity that causes a variable phenotype, from a fatal neonatal onset to neurodegenerative disorders in adulthood. Problem Studied: We report 2 siblings, 5 and 2 years of age, with nystagmus, ataxia, impaired consciousness, hemiparesis, hyporeflexia, and psychomotor regression. In brain magnetic resonance imaging, signal abnormalities in large regions of the cerebral white matter were observed, suggesting a demyelinating disease. Materials and Methods: Genomic DNA was obtained from whole blood. The complete coding region of NDUFV1 was amplified in patients and their parents. Each amplicon was purified. Direct sequencing was performed. Intron 6 and exon 7 amplicons from patient 1 were cloned. A skin biopsy was performed in the mother. RNA was isolated. The NDUFV1 complementary DNA (cDNA) was amplified and directly sequenced. In silico analysis was performed. Following diagnosis, treatment with ubiquinol and riboflavin was started. Results: Both patients have the missense mutation c.1156C> T and the 42-base pair deletion in the gene NDUFV1. Bioinformatics analysis indicates that this deletion leads to messenger RNA (mRNA) synthesis with a premature stop codon. Probably, mutant mRNAs were recognized and degraded by the nonsense-mediated mRNA machinery. Analysis of the maternal NDUFV1 cDNA supports this hypothesis. Conclusion: Our results add information on the molecular basis and the phenotypic features of mitochondrial disease caused by NDUFV1 mutations. We can affirm that the mutations are causative of the phenotype. The patients are having a good therapeutic response to the treatment.
- ÍtemSolo Metadatos344 Point of Care Ultrasonography Training in Bogotá Emergency Medicine Residencies: The Unmet Need(2012-10) Henwood, P.C.; Norwood, B.R.; Genthon, A.A.; Silva, D.; Martinez, Y.B.; Granada, J.; Torres, J.; Romero, M.G.; Arbelaez, C.Background: As ultrasonography equipment has evolved toward increased portability, higher quality and lower cost, the field of point-of-care ultrasonography has grown, with numerous applications for emergency medicine practitioners. Competence in goal-directed ultrasonography image acquisition and interpretation is now a mandatory part of emergency medicine residency training in the United States and the United Kingdom. Appropriate training is a key component to the safe and effective use of this technology. In Colombia, emergency medicine is a relatively new specialty and leaders in the field have expressed interest in further integrating pointof-care ultrasonography into emergency medicine practice and resident training. Study Objectives: The objective of this study was to conduct a needs assessment to better understand the current state of point-of-care ultrasonography practice among all emergency medicine residency programs in Bogotá, Colombia. Methods: An ultrasonography needs assessment survey tool was distributed to all available residents of the 3 emergency medicine residency programs in Bogotá. The emergency medicine program directors, other physicians staffing the emergency departments, and several medical students rotating in the emergency departments were also surveyed. The needs assessment survey tool assessed the population’s experience with point-of-care ultrasonography, formal ultrasonography education, and interest in educational initiatives. Focus group sessions with 50% of emergency medicine residents in Bogotá were subsequently conducted to further qualify their perspective on the current state of diagnostic ultrasonography at each residency training site as it relates to their clinical and procedural practice. Partners Health care institutional review board exemption was obtained for this research. Results: Fifty four total clinicians (43 emergency physicians, 5 non-emergency physicians and 6 medical students) completed the survey. Twenty-nine participants (54%) had previously used an ultrasonography machine. Of all emergency medicine respondents, 24 had used ultrasonography, and trauma was the most common application. However, 52% of those who had used ultrasonography had performed less than 10 independent scans. Thirty-nine participants (72%) had received no formal ultrasonography training. Of respondents, 94% total (100% of emergency physicians) reported a high level of interest in learning point-of-care ultrasonography, particularly trauma and vascular access applications. The major barriers identified by those surveyed were the absence of teachers (83%), the absence of ultrasonography equipment (65%), and time limitations (39%). Focus group discussions revealed that the scope of clinical practice, especially regarding procedures performed by emergency physicians, varied between emergency departments and residencies, but all reported they wanted more training in the use of point-of-care ultrasonography to improve their practice and patient care. Conclusion: Emergency ultrasonography training and use in clinical practice among emergency medicine residencies in Bogotá is currently limited by the lack of ultrasonography equipment and educators. However, there is significant interest in educational initiatives among all residents and program directors. Further research into how to best integrate point-of-care ultrasonography into emergency medicine practice and resident training in Colombia is needed.
- ÍtemSolo MetadatosA new proposal of quality indicators for clinical engineering: A New Beginning for Human Health: Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and Biology Society(2003-01-01) Miguel Cruz, Antonio; Rodriguez, E.; Sanchez, M.C.; Tolkmitt, F.; Pozo, E.As we know from Stiefels paper '...we want to do our work right the first time and better the next time. But we really don't know whether we have done it right, or are doing it better, unless we have a measurement system for quality.' Unfortunately, there is little agreement in the standardization of indicators used for evaluation of organizations related to medical equipment management. And those that do the first steps, always walk on thin ice. With this paper, we suggest a set of five quality indicators for the control and the evaluation of management for medical equipment maintenance. The indicators proposed allow the organization, that applies them, to easily correct and adjust their management programs, with a strive for improvement in results and quality and broadening their experiences. The selection of the indicators was executed according to those that are most used among leading health care organizations. Sometimes the indicators are labeled differently but the basic idea is the same, and therefore the results can be compared competitively and the potential of an organization can be displayed.

- ÍtemSolo MetadatosAB0403 Cigarette smoking and coffee consumption independently influence the risk of developing cardiovascular disease in systemic lupus erythematosus(2013-06) Amaya-Amaya, J.; Pérez-Fernández, J. L.; Molano González, Nicolás; Mantilla, R. D.; Rojas-Villarraga, A.; Anaya, Juan-ManuelBackground Cardiovascular disease (CVD) is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE), a 50-fold than general population. Traditional risk factors, such as, cigarette smoking and dyslipidemia, are known but they cannot fully account for the increased risk. Instead, non-traditional risk factors, related to disease are also contributing. Varied results have been reported on the association between coffee drinking and CVD in the general population, with controversial results. Coffee consumption has not been evaluated systematically in SLE patients with CVD.

- ÍtemSolo MetadatosAgencia Moral y Construcción de Paz(2017-01-01) Ramírez Rueda, Luisa Fernanda; Gutiérrez Peláez, MiguelEn dos intentos previos de negociación de paz, como ahora, los gobiernos de Belisario Betancurt (1982-1986) y de Andrés Pastrana Arango (1998-2002) se situaron como mediadores de las relaciones entre los actores del conflicto y la sociedad civil. Posteriormente en ambos casos, se evidenció un fortalecimiento de la extrema derecha dando lugar al Genocidio de la Unión Patriótica, y al fortalecimiento del paramilitarismo y a las mayores cifras de desplazamiento forzado en la historia de Colombia. En ambos casos, una posible explicación del fracaso tiene que ver con la incapacidad de estos gobiernos para alinear a toda la sociedad con sus objetivos. Tras el último proceso de negociación emprendido por el gobierno de Juan Manuel Santos (2012-2016) con la guerrilla de las FARC (Fuerzas Armadas Revolucionarias de Colombia), el gobierno y la sociedad colombiana se enfrentan una vez más con el reto de reunir el apoyo suficiente para lograr una implementación exitosa los acuerdos logrados. Los resultados recientes del Plebiscito por la paz (Octubre de 2016) y el aumento registrado desde el 2016 en los asesinatos de líderes de izquierda, ponen en evidencia que el reto sigue vigente. Un aspecto a considerar consiste en que el involucramiento de la población en el proceso de construcción de paz depende de que exista un proceso de reflexión moral. Cuando no es así, la desconexión moral contribuye al rechazo de la población a las políticas de reparación y a la emergencia de comportamientos destructivos que amenazan el proceso. Esta ponencia explora la existencia de indicadores de desconexión moral y algunos factores predictores de la misma, así como su relación con al apoyo a los acuerdos de paz entre el gobierno y las FARC
- ÍtemSolo MetadatosAntidepressants in painful diabetic neuropathy(2008-08) Gutierrez Alvarez, A.M.; Moreno, C.B.Background: The incidence of diabetic neuropathy increases withthe duration of diabetes and the degree of hyperglycaemia. Pain isone of the most common and incapacitating symptoms of diabeticneuropathy and its pharmacological control is complex. The effec-tiveness of antidepressive agents has been described in differenttypes of neuropathic pain, but their effectiveness when used as anal-gesics in painful diabetic neuropathy still remains controversial.The objective was to review the possible role of antidepressiveagents for the treatment of pain in diabetic peripheral neuropathy.Thus, this work has consisted of meta-analysis for determiningwhich antidepressive agent had the best analgesic potential for man-aging pain in patients suffering from painful diabetic neuropathy.Methods: The search covered the Cochrane, MEDLINE,EMBASE and LILACS databases, between January 2000 andAugust 2007. The following information was obtained from eacharticle: criteria for diagnosing diabetic neuropathy, patients’ aver-age age, antidepressant drug received and dose, sample size, dura-tion of the disease and treatment follow-up, outcome measure-ment, evaluation of pain and rescue medication.Results: A combined RR: 1.67 (95% CI 1.38–2.02) was obtained;this result indicated that the antidepressive agents studied wereeffective for controlling pain in diabetic neuropathy. The corre-sponding NNT for Duloxetine was established, according to ourinterests; NNT = 6 (95% CI 5–8) for achieving greater than 50%analgesia in patients suffering from painful diabetic neuropathy.Conclusion: Antidepressive agents are frequently employed in thespecific case of diabetic neuropathy; the combined result of thismeta-analysis has demonstrated their analgesic benefit.
- ÍtemSolo MetadatosAntinuclear autoantibodies: Discordance among four different assays(2020) Pacheco Nieva, Yovana; Monsalve Carmona, Diana Marcela; Acosta Ampudia, Yeny Yasbleidy; Rojas, Cilia; Anaya, Juan-Manuel; Ramírez Santana, Heily CarolinaDetection of antinuclear antibodies (ANAs) is of paramount importance for diagnosis and assessment of autoimmune diseases (ADs), but may vary depending on the method used. Therefore, we aimed to compare three different line immunoassays (LIAs) for ANAs testing in order to simultaneously evaluate their concordance with the results obtained by a well known and widely used ELISA.

- ÍtemSolo MetadatosBarriers to implementation of Evidence-Based Practice (EBP): a survey of Colombian and Spanish physiotherapists(2015-05-01) Girabent-Farrés, M.; Bagur-Calafat, C.; Serra-Llobet, P.; Sánchez-Puccini, M.B.; Domínguez-Sánchez, M.A.; Correa-Bautista, J.E.; Flórez-López, M.E.; Ramírez-Vélez, R.In countries such as Australia, Spain, United States, Colombia, and United Kingdom, the use, teaching and evaluation of ‘evidence-based physical therapy’ (EBPT) in clinical practice has been recently included in educational curriculum. As consequence, PT have support the EBPT, proposing a series of initiatives designed to generate, evaluate and disseminate research, and to implement these results in practice. Despite most research has focused on the use of evidence, including a critical review of studies and scientific literature in clinical practice, if it is desiderate that the use of EBP becomes a reality, it is important to examine the numerous perceived barriers to using research in clinical settings, despite the paucity of studies in this topic. This is especially true for professions such as physiotherapy that has a small research base and few resources compared with other professions. Typically, barriers are context-dependent; therefore, the implementation of strategies should be tailored according to the context and the specific barriers identified. The most commonly reported barrier among PT is the limited time, which constrains the identification and interpretation of research evidence, as well as the ability to apply research findings in clinical practice.

- ÍtemSolo MetadatosCambios en el periodismo, cambios en la audiencia.(2009-01-01) Zúñiga Reyes, Danghelly GiovannaLa tecnología permite hoy a los ciudadanos participar más activamente en los medios de comunicación. Para examinar la transformación del ciudadano en periodista, veremos si los ciudadanos que participan por distintas vías en dos diarios digitales de Colombia (El Tiempo y El Espectador) definen y dan forma a las noticias o si los periodistas son los únicos árbitros de lo que es de interés periodístico, ciudadano y democrático. Las ventajas que brinda la red para el periodismo son evidentes: la velocidad, la eficiencia de la entrega, la selectividad personal, la disponibilidad en demanda, la posibilidad de tener casi un costolibre, la posibilidad para almacenar el contenido adicional y aceptar a usuarios adicionales (Steiger, 2006) además de la interactividad, la hipertextualidad, la multimedialidad y la asincronidad (Bardoel, 2002). Para analizar la relación usuario-periodista partimos del hecho de que las noticias se han transformado debido a la concentración de los medios informativos en grandes empresas. Para Cohen (2002) esta concentración es el primer plano de la transformación en la práctica del periodismo en línea. Cohen identifica tres aspectos que son relevantes para el periodismo digital y que a su vez permiten identificar las posibles formas de fractura de la muralla que establecen los grandes conglomerados.
- ÍtemSolo MetadatosCapacity Utilization in Electricity Market Behavior: An Experimental Analysis(2019) Castañeda, Jaime Andrés; Arango Aramburo, SantiagoThis paper describes a laboratory experiment of electricity markets to study the effect of variable capacity utilization over market dynamics. Previous experiments have left out a potential source of cyclical behavior by assuming full capacity utilization. We run 12 experimental markets of the power generation sector, involving two treatments: a first treatment with fixed (full) capacity utilization where subjects make investment decisions, and a second treatment where subjects make both investment and capacity utilization decisions. Visual inspections, basic statistics and simulation tests run with decision rules estimated from experimental data show that the markets run under full capacity utilization present a cyclical behavior in market development. Conversely, such tests show a noncyclical market development for the markets run under variable capacity utilization, suggesting that varying capacity utilization favors stability rather than a cyclical behavior.
- ÍtemSolo MetadatosCase studies in the application of an effective anticollision risk management standard(2010) Poedjono, Benny; Avila, Carlos; Phan Van, Chinh; Isevcan, Erhan; Walker, John; Gonzalez, Luis Felipe; McCulloch, Simon; Juárez, Fernando; Moreno, Victor HugoEconomic, regulatory, and technological changes have steadily increased the oil and gas industry's need for an effective approach to assessing and managing the risk of well collisions. We have developed such an approach, which has been used successfully in recent years in a number of major land and offshore drilling projects worldwide. This approach has been adopted as a standard by the major oilfield service company of which we are a part. In this paper, we describe four recent experiences in which this standard has been applied, and discuss the challenges of its implementation and the economic, environmental, and health and safety benefits it provides. Based on its proven success, we make a case for using this approach as a foundation for development and adoption of an industry-wide anticollision and risk management standard.
