    Antecedentes: La alta incidencia de eventos cardiovasculares en la población anciana ha demostrado la eficacia de las estatinas en la reducción de la mortalidad por eventos coronarios; sin embargo, se han producido efectos adversos, tales como mialgia, miopatía, mionecrosis, sin mencionar las caídas como consecuencia de dano˜ muscular con el uso de estatinas. Objetivo: El objetivo de este estudio es realizar una revisión sistemática para evaluar la literatura sobre la asociación entre el uso de estatinas y el riesgo de caídas. Métodos: Las bases de datos que se incluyeron (PubMed y SCOPUS) con artículos publicados entre enero de 2000 y mayo de 2016. Los términos MESH utilizados para la búsqueda fueron «FALLS» AND «STATIN». Los estudios seleccionados incluyeron cohortes de población de la comunidad (> 50 anos) ˜ y fue analizado siguiendo las recomendaciones metodológicas SIGN (Scottish Intercollegiate Guidelines Network), ya que no se encontró ningún estudio controlado aleatorizado. Resultados: En el estudio de Ham et al. el uso de estatinas ha demostrado ser un factor protector para la presencia de caídas. En el segundo estudio realizado por Scott et al. se encontró un aumento del riesgo de caídas (p = 0,029) y un deterioro de la fuerza muscular y la calidad del músculo (valor de p = 0,033 y 0,046, respectivamente). En el tercer estudio Haerer et al. se encontró un mayor riesgo de caídas (p = 0,63). Conclusiones: La evidencia disponible no permite determinar la asociación entre el uso de estatinas y el riesgo de caídas, aunque sí se encontró asociación con el compromiso de algunos determinantes de la función muscularQ3Artículo original317-321Background: With the high incidence of cardiovascular events in the elderly population the effectiveness of statins in reducing mortality from coronary events has been demonstrated. However, there have been adverse effects, such as myalgia, myopathy, myonecrosis, not to mention the falls as a result of muscle damage with statin use. Objective: The purpose of this study is to conduct a systematic review to assess the literature on the association between statin use and the risk of falls. Methods: The databases that were included PUBMED AND SCOPUS, with articles published from January 2000 to May 2016. The MESH terms used for the search were “FALLS” AND “STATIN”. Selected studies included cohort populations from the community (> 50 years old), and analysed using the Scottish Intercollegiate (SIGN) methodology guidelines, as no randomised controlled study was found. Results: In the study by Ham et al., statin use was shown to be a protective factor for presence of falls. In the second study by Scott et al., there was an increased risk of falls (P = .029) and an impairment in muscle strength and quality muscle (P = .033 and P = .046, respectively). In the third study Haerer et al., found an increased risk of falls (P = .63). Conclusions: The association between use of statins and risk of falls could not be determined with the available evidence, although an association with the involvement of some determinants of muscular function was foun

    Introducción: La lactancia materna es la acción natural de alimentar al bebé con leche producida por la madre, o por una madre sustituta que asuma ese papel, pero existen factores que la favorecen y la limitan. La leche materna es el primer alimento natural que proporciona al bebé energía y nutrientes necesarios durante los primeros meses, esta contribuye a la maduración neurológica, funcional del tracto gastrointestinal y renal, promueve desarrollo sensorial, cognitivo y desarrollo de los mecanismos de defensa inmunes, protegiendo al bebé de enfermedades e infecciones crónicas.Objetivo: Describir las limitaciones de la lactancia materna exclusiva, a partir de la revisión literaria de estudios de investigación en el período de 2005-2015.Materiales y métodos: El tipo de investigación fue una revisión documental integrativa no sistemática. La población estuvo conformada por 100 publicaciones que hicieron parte de la revisión, quedando 50 artículos que aportaron a construir el documento; la muestra la conformaron 15 artículos, los criterios de inclusión fueron artículos del periodo 2005-2015 y los criterios de exclusión fueron artículos no científicos, boletines informativos, artículos fuera del periodo 2005-2015.Resultados: La lactancia materna exclusiva, sin otros alimentos ni líquidos, durante los primeros 6 meses de vida tiene ventajas en comparación con la lactancia materna exclusiva durante solo 3 a 4 meses, seguida de la combinación de la lactancia materna con otros alimentos.Conclusión: Es vital fomentar la lactancia materna exclusiva porque es un compromiso social extenso y continuo no sólo con las madres, también con el personal de salud específicamente con las enfermeras

    (1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD-Crohn's disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)-during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31-56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery

    En Colombia, actualmente no existen parámetros claros para el diagnóstico de pacientes con talla baja, ni sobre el tratamiento de esta población con hormona de crecimiento recombinante humana (somatropina), lo cual se ve favorecido por la diversidad de programas de formación de profesionales en endocrinología pediátrica. En respuesta a esta problemática se realizó el primer acuerdo colombiano de expertos en talla baja liderado por la Asociación Colegio Colombiana de Endocrinología Pediátrica (ACCEP); este trabajo contó con la participación y el aval de expertos clínicos de importantes instituciones de salud públicas y privadas del país, además de expertos metodológicos del instituto Keralty, quienes garantizaron la estandarización del uso de la somatropina. Después de realizar una minuciosa revisión de la literatura, se propone la unificación de definiciones, un algoritmo diagnóstico, los parámetros de referencia de las pruebas bioquímicas y dinámicas, una descripción de las consideraciones de uso de la somatropina para el tratamiento de las patologías con aprobación por la entidad regulatoria de medicamentos y alimentos en Colombia y, por último, un formato de consentimiento informado y de ficha técnica del medicamento.In Colombia there are no guidelines for diagnosis and management of patients with short stature and for the use of recombinanthuman growth hormone, mainly caused by the diversity of training centers in pediatric endocrinology. In response to this situation,the Asociación Colegio Colombiana de Endocrinología Pediátrica leds the first colombian short stature expert committee in order tostandardize the use of human recombinant growth hormone. This work had the participation and endorsement of a consortium ofclinical experts representing the Sociedad Colombiana de Pediatría, Secretaría Distrital de Salud de Bogotá- Subred Integrada deServicios de Salud Suroccidente, Fundación Universitaria Sanitas, Universidad de los Andes and some public and private healthinstitutions in the country, in addition to the participation of methodological experts from the Instituto Global de Excelencia ClínicaKeralty. By reviewing the literature and with the best available evidence, we proposed to unify definitions, a diagnostic algorithm,biochemical and dynamic tests with their reference parameters, a description of the considerations about growth hormone use amongthe indications approved by regulatory agency for medications and food in Colombia and finally a proposal for an informed consentand a medication fact sheet available for parents and patients.https://orcid.org/0000-0002-7856-7213https://orcid.org/0000-0003-2241-7854Revista Nacional - Indexad

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
