Mechanical properties of artisanal bricks

One of the problems facing construction now is obtaining materials that meet certain conditions of durability and resistance, before weathering or natural phenomena, this work shows the study of the mechanical properties of clay bricks that have were made by hand, between three different brickyards near the Portoviejo canton, here a comparison is made by applying the Ecuadorian standards. The tests allowed performing the comparisons of moisture absorption, compression resistance, and flexural strength test. Field visits, interviews, laboratory tests and tabulation of results have were used as a methodology. The software has was used to make the graphs and statistical tables for its interpretation. As a result of the research, it was found that of the three artisan brick kilns studied. They only meet one of the three criteria established by the INEN. The test that showed the best results was the resistance to bending, while the absorption moisture and resistance to compression results that are below the parameters established in the standard, a situation that is of interest to the community, because a large percentage of the population close to these artisan brick kilns, build their homes with this material

Expansion of serotype coverage in the universal pediatric vaccination calendar: Short-term effects on age- and serotype-dependent incidence of invasive pneumococcal clinical presentations in Madrid, Spain

In Madrid, Spain, the 13-valent pneumococcal conjugate vaccine (PCV13) replaced PCV7 in the pediatric universal vaccination calendar in June 2010. A prospective clinical surveillance that included all children hospitalized with culture- and/or PCR-confirmed invasive pneumococcal disease (IPD) was performed in all Madrid hospitals. The incidence rates (IRs) (defined as the number of cases/100,000 inhabitants aged<15 years) in the PCV7 (May 2007 to April 2010) versus PCV13 (May 2011 to April 2012) periods were compared. There were 499 cases in the PCV7 period and 79 cases in the PCV13 period. Globally, the IR significantly decreased from 17.09 (PCV7 period) to 7.70 (PCV13 period), with significant decreases (PCV7 versus PCV13 periods) in all age groups for bacteremic pneumonia (5.51 versus 1.56), parapneumonic pneumococcal empyema (PPE) (5.72 versus 3.12), and meningitis (2.16 versus 0.97). In the PCV13 period, significant reductions (the IR in the PCV7 period versus the IR in the PCV13 period) were found in IPDs caused by PCV13 serotypes (13.49 versus 4.38), and specifically by serotypes 1 (globally [4.79 versus 2.53], for bacteremic pneumonia [2.23 versus 0.97], and for PPE [2.26 versus 1.17]), serotype 5 (globally [1.88 versus 0.00], for bacteremic pneumonia [0.89 versus 0.00], and for PPE [0.55 versus 0.00]), and serotype 19A (globally [3.77 versus 0.49], for bacteremic pneumonia [0.72 versus 0.00], for PPE [0.89 versus 0.00], and for meningitis [0.62 versus 0.00]). IPDs caused by non- PCV13 serotypes did not increase (IR, 3.60 in the PCV7 period versus 3.31 in the PCV13 period), regardless of age or presentation. No IPDs caused by the PCV13 serotypes were found in children who received 3 doses of PCV13. The number of hospitalization days and sanitary costs were significantly lower in the PCV13 period. The switch from PCV7 to PCV13 in the universal pediatric vaccination calendar provided sanitary and economical benefits without a replacement by non-PCV13 serotypesThis work was supported in part by an unrestricted grant from Pfizer S.L.U., Madrid, Spain.

Relationship between serotypes, age, and clinical presentation of invasive pneumococcal disease in Madrid, Spain, after introduction of the 7-valent pneumococcal conjugate vaccine into the vaccination calendar

To assess invasive pneumococcal disease (IPD) clinical presentations and relationships with age and serotype in hospitalized children (<15 years) after PCV7 implementation in Madrid, Spain, a prospective 2-year (May 2007 to April 2009) laboratory-confirmed (culture and/or PCR) IPD surveillance study was performed (22 hospitals). All isolates (for serotyping) and culture-negative pleural/cerebrospinal fluids were sent to the reference laboratory for pneumolysin (ply) and autolysin (lyt) gene PCR analysis. A total of 330 IPDs were identified: 263 (79.7%) confirmed by culture and 67 (20.3%) confirmed by PCR. IPD distribution by age (months) was as follows: 23.6% (<12), 15.8% (12 to 23), 15.5% (24 to 35), 22.4% (36 to 59), and 22.7% (>59). Distribution by clinical presentation was as follows: 34.5% bacteremic pneumonia, 30.3% pediatric parapneumonic empyema (PPE), 13.6% meningitis, 13.3% primary bacteremia, and 8.2% others. Meningitis and primary bacteremia were the most frequent IPDs in children <12 months old, and bacteremic pneumonia and PPE were most frequent in those >36 months old. Frequencies of IPD-associated serotypes were as follows: 1, 26.1%; 19A, 18.8%; 5, 15.5%; 7F, 8.5%; 3, 3.9%; nontypeable/ other 30 serotypes, 27.3%. Serotype 1 was linked to respiratory-associated IPD (38.6% in bacteremic pneumonia and 38.0% in PPE) and children of >36 months (51.4% for 36 to 59 months and 40.0% for >59 months), while serotype 19A was linked to nonrespiratory IPDs (31.1% in meningitis, 27.3% in primary bacteremia, and 51.9% in others) and children of <24 months (35.9% for children of <12 months and 36.5% for those 12 to 23 months old), with high nonsusceptibility rates for penicillin, cefotaxime, and erythromycin. After PCV7 implementation, non-PCV7 serotypes caused 95.5% of IPDs. The new 13-valent conjugate vaccine would provide 79.1% coverage of serotypes responsible for IPDs in this series

GABA and Dopamine Release from Different Brain Regions in Mice with Chronic Exposure to Organophosphate Methamidophos

Organophosphates such as methamidophos, usually used in the agricultural field, have harmful effects on humans. Exposures to insecticides has been associated with many disorders, including damage to the central and peripheral nervous system. Chronic exposure to organophosphates may lead to persistent neurological and neurobehavioral effects. This study was conducted to determine the effect of methamidophos on [3H]-dopamine (DA) and gamma aminobutyric acid (GABA) release from different brain regions after chronic exposure to it for 3, 6 or 9 months. After a six-month methamidophos treatment, the mice showed high susceptibility to convulsive seizures and a reduction in stimulated gamma aminobutyric acid release from the cerebral cortex and hippocampal slices, whereas stimulated (DA) release was slightly decreased from the striatum after three months of methamidophos exposure. The results indicate changes in gamma aminobutyric acid and dopamine neurotransmission, suggesting a specific neuronal damage

Capacidad para la investigación clínica : un avance conceptual y metodológico

La reciente alianza interinstitucional de la Universidad del Rosario con la Orden Hospitalaria de San Juan de Dios y la Caja de Compensación Familiar (Compensar), como red hospital- universitario representa una gran oportunidad para consolidar la capacidad de generar conocimiento sobre los principales temas de salud que el país confronta, y de aplicarlo a mejorar los servicios de salud en el Distrito Capital y en Colombia. Recientes estudios adelantados por la Facultad de Economía de la Universidad del Rosario1 muestran claramente la forma como en América Latina ha surgido una importante comunidad de investigación en temas clínicos (investigación clínica), convirtiendo al hospital tradicional en una organización del conocimiento. A fin de que los hospitales tengan la capacidad de responder a los desafíos que confrontan en la sociedad del siglo XXI, deben conocer y desarrollar su capacidad para convertirse en hospitales de conocimiento, en particular aquel que se deriva de la práctica e investigación clínica. Ello pasa por dimensionar la capacidad de las organizaciones y los individuos para conducir investigación, usar sus resultados y transferirlos de manera eficiente, efectiva y sostenible. Alineadas con esta realidad, las facultades de Medicina y Rehabilitación y Desarrollo Humano de la Universidad del Rosario, que hoy conforman la nueva Escuela de Medicina y Ciencias de la Salud, a través de los grupos de investigación en Rehabilitación e Integración Social de la Persona con Discapacidad y de Investigación Clínica, participaron de la convocatoria 2008 del Fondo de Investigación de la Universidad del Rosario, con el proyecto denominado “Capacidad para la Investigación Clínica en la Red Hospitalaria Méderi”, cuyo objetivo es caracterizar la capacidad para la investigación clínica en la red local de hospitales de Méderi, y definir estrategias de desarrollo y fortalecimiento de dicha capacidad, con miras a convertirse en un hospital de conocimiento. Con este fin, se planteó realizar un análisis diagnóstico de la capacidad existente para hacer investigación clínica en la red hospitalaria Méderi, y proyectar dicha capacidad con el fin de lograr sus objetivos. Para este análisis se está desarrollando una “estructura analítica mixta” que permitirá caracterizar la estructura y organización de la red hospitalaria
