Relativistic Spinor Dynamics Inducing the Extended Lorentz-Force-Like Equation

The special relativistic dynamical equation of the Lorentz force type can be regarded as a consequence of a succession of space-time dependent infinitesimal Lorentz transformations as shown by one of us \cite{buitrago} and discussed in the introduction below. Such an insight indicates that the Lorentz-force-like equation has an extremely fundamental meaning in physics. In this paper we therefore present a set of dynamical Weyl spinor equations {\em inducing} the extended Lorentz-force-like equation in the Minowski space-time. The term extended refers to the dynamics of some additional degrees of freedom that may be associated with the classical spin namely with the dynamics of three space-like mutually orthogonal four-vectors, all of them orthogonal to the linear four-momentum of the object under consideration.Comment: 15 page

Spectroscopy of the Lens Galaxy of Q0957+561A,B. Implications of a possible central massive dark object

We present new long-slit William Herschel Telescope spectroscopic observations of the lens galaxy G1 associated with the double-imaged QSO 0957+561A,B. The obtained central stellar velocity dispersion, sigma_l = 310 +/- 20 km/s, is in reasonable agreement with other measurements of this dynamical parameter. Using all updated measurements of the stellar velocity dispersion in the internal region of the galaxy (at angular separations < 1".5) and a simple isotropic model, we discuss the mass of a possible central massive dark object. It is found that the data of Falco et al. (1997) suggest the existence of an extremely massive object of (0.5-2.1) x 10E10/h M_\odot (80% confidence level), whereas the inclusion of very recent data (Tonry & Franx 1998, and this paper) substantially changes the results: the compact central mass must be $\le$ 6 x10E9/h M_\odot at the 90% confidence level. We note that, taking into account all the available dynamical data, a compact nucleus with a mass of 10E9/h M_\odot (best fit) cannot be ruled out.Comment: 20 pages, 10 figures ApJ, in pres

Bovine Tuberculosis Testing in Colombia: Comparative Histopathological, Microbiological, and Molecular Biology Findings

Introduction: Bovine tuberculosis (bTB) is a zoonotic infectious disease present in Colombia, caused by Mycobacterium bovis, and causes tuberculosis in water buffalo (Bubalus bubalis). Diagnosis of bovine tuberculosis through the intradermal test is difficult; evaluating and understanding the behavior of other diagnostic tests is necessary. Objective: To describe the behavior and results of different diagnostic methods for bovine tuberculosis in water buffalo positive for the Purifed Proteic Derivate (DPP) intradermal test. Methodology: In water buffaloes positive for comparative cervical tuberculin test, different diagnostic methods were applied, described, and compared: Ziehl-Neelsen staining, microbiological culture, histopathological analysis, and PCR-HRM. Results: Histopathological tests showed that 26 water buffalo positive for DPP (52%) had histological lesions compatible with bovine tuberculosis. 37% of the evaluated samples from tuberculin-positive Buffalo's lungs and secondary lymph nodes showed acid-alcohol-resistant bacillus with Ziehl-Neelsen staining. Four samples of Mycobacterium bovis from tuberculin-positive buffalo were isolated and identified, with two of these isolates confirmed from tissues with PCR-HRM, and three buffalo with microbiological isolates presented granulomatous lesions through histological analysis. Seventeen tuberculin-positive buffalo (34%) tested positive for real-time PCR HRM, and nine of these buffalo did not have histological lesions compatible with bTB and were confirmed with the molecular test. Conclusion: Our results provide positive evidence of histological findings, microbiological isolation, and molecular diagnosis of tuberculin-positive water buffalo in the lowlands of Colombia. None of the complementary tests performed showed 100% concordance with the comparative cervical tuberculin test results for bTB

Screening for malnutrition among hospitalized patients in a Colombian University Hospital

Q4Q3Artículo de investigación449-457Pacientes del Hospital San IgnacioBackground: On admission, 30 to 50% of hospitalized patients have some degree of malnutrition, which is associated with longer length of stay, higher rates of complications, mortality and greater costs. Aim: To determine the frequency of screening for risk of malnutrition in medical records and assess the usefulness of the Malnutrition Screening Tool (MST). Material and Methods: In a cross-sectional study, we searched for malnutrition screening in medical records, and we applied the MST tool to hospitalized patients at the Internal Medicine Wards of San Ignacio University Hospital. Results: Of 295 patients included, none had been screened for malnutrition since hospital admission. Sixty one percent were at nutritional risk, with a higher prevalence among patients with HIV (85.7%), cancer (77.5%) and pneumonia. A positive MST result was associated with a 3.2 days increase in length of hospital stay (p = 0.024). Conclusions: The prevalence of malnutrition risk in hospitalized patients is high, but its screening is inadequate and it is underdiagnosed. The MST tool is simple, fast, low-cost, and has a good diagnostic performance

Caracterizacion del riesgo por fenomenos naturales de la comunidad de La Plata (bahia Malaga)--Pacifico Colombiano

Resumen: El presente artículo realiza caracterización de los fenómenos naturales amenazantes sobre el territorio de la Bahía de Málaga, que unido a las condiciones sociales y económicas de la población, configuran unas situaciones especiales de riesgo. Se explica cómo frente a estas situaciones la comunidad se ha organizado políticamente y decidido afrontar un proceso de reubicación que pasó fundamentalmente por la escogencia de un sitio condiciones de menor vulnerabilidad. ABSTRACT: This article conducts characterization of the natural phenomena hazard on the territory of the Bahia Málaga, coupled with the social and economic conditions of the population, make up some special situations of risk. It explains how to address these situations, the community is organized politically and decided to confront a process of relocation happened mainly by the choice of a site with less vulnerability conditions

Frecuencia y factores de riesgo asociados a la cefalea postparto en el Hospital universitario Erasmo Meoz de San José de Cúcuta

ResumenEl dolor es una experiencia sensorial desagradable, asociada a daño tisular real, como resultado de una interacción de múltiples variables biológicas, psicológicas, sociales y culturales. La cefalea posparto es definida como la sensación subjetiva de dolor que se puede manifestar a nivel de la cabeza, cuero cabelludo o cara, conocido en el lenguaje coloquial como “dolor de cabeza” que puede variar tanto en un número de episodios como de intensidad además de tener una incidencia de un 39% en la primera semana generando una limitación funcional significativa del 4 %. Mediante un estudio descriptivo se pretendió identificar los factores de riesgo asociados a la cefalea posparto en las pacientes gestantes, por un periodo de tres meses durante el año 2013 en el servicio de Obstetricia del Hospital Universitario Erasmo Meoz, centro de referencia en la región para las gestantes de Alto Riesgo Obstétrico del departamento Norte de Santander, Arauca y región fronteriza venezolana. Mediante encuestas aplicadas a las pacientes posparto se  identificó y correlacionó los  factores  de  riesgo  asociados a  la cefalea postparto teniendo en cuenta el tipo de parto (parto vaginal versus cesárea) y de esta manera se buscó responder a la escasa información detectada en Colombia y particularmente en el Departamento Norte de Santander, sobre la aparición del evento; con el fin de abrir la posibilidad para nuevas discusiones en la generación de herramientas que favorezca aún más los controles de calidad propios del HUEM, vigentes en el momento actual

Impacto social y económico de los sismos, deslizamientos e inundaciones sobre la vivienda en Pereira, 1960-2002

Se hace una reflexión sobre los desastres y sus riesgos y se presentan algunos resultados de la investigación que, mediante el desarrollo de una metodología, valoró los impactos que sobre el sector vivienda del área urbana de la ciudad de Pereira han originado los sismos, las inundaciones y los deslizamientos en el período comprendido entre 1960 y 2002. Se encontró que durante el período de estudio las pérdidas económicas superaron el billón de pesos calculados en valor de 2004, que el número de viviendas destruidas y averiadas equivale a más de las viviendas que tenía la ciudad en la década del 60, que han fallecido por esta causa 212 personas y que han sufrido lesiones 1315. Además, los deslizamientos fueron una constante en toda la ciudad y las personas de estrato bajo han sido las más afectadas por estos eventos desastrosos

Consenso colombiano para el manejo de pacientes con Hipofosfatasia

La hipofosfatasia (HPP) es una enfermedad metabólica, de tipo hereditario, causada por mutaciones en el gen ALPL. Teniendo en cuenta los retos del manejo adecuado de los pacientes con HPP, se realizó un consenso interdisciplinario de expertos (endocrocrinólogos pediatras, nefrólogos pediatras, ortopedistas infantiles y genetistas clínicos) con el fin de proponer recomendaciones de utilidad clínica para el diagnóstico, tratamiento y seguimiento de los pacientes colombianos con HPP. Estas sugerencias se realizan en el contexto de los diferentes tipos de presentaciones y las edades de los pacientes.Q41-7Hypophosphatasia (HPP) is a hereditary metabolic disease caused by mutations in the ALPL gene.
