It will be succesful to have a commercial relation between France and Colombia focus on the milk sector ?

Globalization has led to a drastic change on the international trade, this has caused that many countries such as France and Colombia find new business partners. This is the raison because I develop the investigation about How these countries can be integrated commercially in the dairy sector? Colombia and France had active trade relations for more than 8 years, but this has been declining for several factors. In the case of France, it has found that Germany is an excellent producer of raw milk, which can supply domestic demand and can export large quantities with a low price to European countries because of its proximity. For this reason, Colombia is a country that can not compete with Germany directly in raw milk, but I concluded that Colombia could become a major competitor with organic milk. This is the result of a research of the way they raise and feed the cows in the two countries, Colombia is generally on open country and Germany is on cow housing. In Colombia, the country found that Venezuela could offer many benefits in the processing of raw milk, and other processes that require high technology. But today Colombia has had several disputes with Venezuela and many Colombian companies are affected in this sector. Additionally, France is one of the largest producers and distributors of processed milk and its derivatives; it launches annually many manufactured products with high technology. At this point, Colombia can take out the best advantage because it can create an strategic alliance with French companies to bring most innovative and processed products such as cheese and yoghurts. The theoretical framework of this thesis consists on the analysis of competitiveness, because it is relevant to see if these two countries are competitive or if one has the comparative advantage over the other. The related authors are: Michael Porter, Adam Smith and David Ricardo. To complete the theoretical part, we found that France has a comparative advantage over Colombia in this sector thanks to its high technology, and Colombia is not currently competitive in the area of raw milk because the milk price is higher and the distance is a barrier, and it has no technology. But this research indicates that Colombia could become a competitive country selling organic milk.

Should rituximab be considered as the first-choice treatment for severe autoimmune rheumatic diseases?

The present study aimed to assess the tolerance and efficacy of rituximab (RTX), a chimeric IgG1 monoclonal antibody directed against the CD20 receptor present in B lymphocytes, in patients with autoimmune rheumatic diseases (AIRD). For this purpose, patients treated with RTX and their respective clinical charts were comprehensively examined. Indications for treatment were a refractory character of the disease, inefficacy or intolerance of other immunosuppressors. Activity indexes (SLEDAI, DAS28, and specific clinical manifestations) were used to evaluate efficacy. Serious side effects were also recorded. Seventy-four patients were included. Forty-three patients had systemic lupus erythematosus (SLE), 21 had rheumatoid arthritis (RA), 8 had Sjögren’s syndrome (SS), and 2 had Takayasu’s arteritis (TA). RTX was well-tolerated in 66 (89%) patients. In 8 patients (SLE = 3, SS = 3, RA = 2), serious side effects lead to discontinuation. The mean follow-up period was 12 ± 7.8 (2–35) months. The efficacy of RTX was registered in 58/66 (87%) patients, of whom 36 (83%) had SLE, 18/21 (85%) had RA, 3/8 (37%) had SS, and 1 had TA. The mean time of efficacy was 6.3 ± 5.1 weeks. A significant steroid-sparing effect was noticed in half of the patients. These results add further evidence for the use of RTX in AIRD. Based on its risk–benefit ratio, RTX might be used as the first-choice treatment for patients with severe AIRD.

Variability in the international normalised ratio (INR) in patients with antiphospholipid syndrome and positive lupus anticoagulant: should the INR targets be higher?

El síndrome antifosfolípido es un desorden autoinmune caracterizado por hipercoagulabilidad que requiere terapia anticoagulante como pilar fundamental, siendo la warfarina el tratamiento de elección en los casos que requieren manejo por largos periodos. Sin embargo, los pacientes con anticoagulante lúpico positivo representan un reto porque tienen mayor riesgo de presentar eventos trombóticos, sumado a que el seguimiento con el International Normalized Ratio (INR) no es confiable, ya que estos anticuerpos generan interferencia con las pruebas de laboratorio basadas en fosfolípidos, como es el caso del tiempo de protrombina (PT) con INR basal prolongado, incluso antes del inicio de la terapia anticoagulante. Por tal razón, se ilustra el caso de una paciente con síndrome antifosfolípido primario y anticoagulante lúpico positivo quien ha presentado múltiples episodios trombóticos, a pesar de recibir terapia anticoagulante. Además se hace una revisión de la literatura disponible y se postulan nuevas metas de INR en estos pacientes diferentes de las que se plantean actualmente.

Caracterización de la función cognitiva de niños con síndrome de down de 5 a 12 años en la ciudad de Bogotá

Los niños que padecen trisomía 21 poseen una serie de características físicas, neurológicas y neuropsicológicas específicas, las cuales han sido investigadas a profundidad en diferentes países, de lo cual se han desarrollado protocolos de evaluación para estos niños acorde a su nacionalidad (García, 2010). A pesar de que Colombia es uno de los países en los cuales el síndrome de Down se presenta con mayor frecuencia, hasta la fecha, no se encuentran estudios que enfaticen en las habilidades neuropsicológicas de esta población específica, por lo cual no se han desarrollado protocolos de evaluación adecuados para los niños con síndrome este síndrome. Esta investigación se llevó acabo con una población de 88 niños a los cuales se les aplicó el inventario de desarrollo BATTELLE, y se identificó que los niños con síndrome Down de 5 a 12 años obtienen un puntaje que se encuentra en 4 desviaciones estándar por debajo de la media típica. Lo anterior demuestra una característica específica de esta población en cuanto a patrones de desarrollo en las cuales, se evidencia dificultad más importante en las área cognición y de la comunicación expresiva. Con respecto a los intervalos de edad se identificó que a lo largo de estos el desempeño en las áreas evaluadas decrece. esto puede estar relacionado con la mayor complejidad de los hitos del desarrollo para una edad esperada. Debido a que los hitos del desarrollo esperados varían a lo largo de los periodos del ciclo vital del ser humano, estos tienden a aumentar su complejidad en etapas del desarrollo más avanzados; como estos niños poseen una serie de dificultades en las funciones ejecutivas y cognición, no lograrán alcanzar dichos hitos del desarrollo.
