Abstract: Se realizó un estudio descriptivo , retrospectivo clínico anatomo-patológico de todos los pacientes fallecidos por un presunto infarto miocárdico agudo, según los resultados de los certificados de defunción emitidos o por los estudios necrópsicos, en el hospital "Abel Santamaría Cuadrado" de Pinar del Rió, desde el 1ro de enero del 2004 hasta el 31 de diciembre del 2005, con el objetivo de contribuir a obtener una estadística de letalidad por IMA que se aproxime objetivamente más a la realidad actual. Entre los resultados más significativos debemos se alar que el 15.9% de los certificados de defunción emitidos por un infarto cardiaco agudo no se correspondió con este diagnóstico, y el análisis de los estudios necrópsicos demostró que el 23.5% de los pacientes fallecidos por esta entidad no se diagnosticaron en vida. Pudo demostrarse que en los ancianos el diagnóstico de esta enfermedad es más difícil de realizar en vida por su sintomatología atípica. Hubo un determinado número de enfermedades o complicaciones propias del infarto agudo que suelen enmascararlo o simularlo clínicamente, siendo las principales las bronconeumonías de evolución tórpida, las crisis hipertensivas, la enfermedad pulmonar obstructiva crónica descompensada y el paro cardiaco. En las salas comunes de cirugía y medicina interna fue donde se cometieron más errores diagnósticos, mientras que los mejores resultados se obtuvieron en la unidad de cuidados coronarios intensivos. Concluimos haciendo hincapié en la necesidad de incentivar la realización de los estudios necrópsicos y de efectuar periódicamente la reparación de los certificados de defunción emitidos por un presunto infarto miocárdico agudo, por los comités de fallecidos hospitalarios. A descriptive, retrospective, clinical anatomopathological study was performed on all the patients deceased due to a so-called acute miocardial infarction, according to the results from the issued death certificates or through the necropsic studies at Abel Santamaría Cuadrado Hospital in Pinar del Río province, from January 1st. 2004 to December 31st. 2005, aimed at helping to obtain mortality statistics due to AMI which are more objectively close to the current reality. Among the most significant results, we should state that 15.9% of the death certificates issued due to an acute miocardial infarction was not consistent with this diagnosis, and the analysis of the necropsic studies showed that 23.5% of the deceased patients due to this entity were not diagnosed when alive. It was demonstrated that in the aged the diagnosis of this disease is ha

Abstract: Suicide is treated by society as a taboo subject despite it being the leading cause of unnatural death in Spain. The Tenerife Province is ranked 16th among the 52 Spanish provinces for its suicide rate. From 2007 till 2010, the rate increased from 2007 to 2008, then dropped in 2010. Slight rise occurred in suicide rates in 2010. This rate increased from 2007 to 2008, with a decrease of rate in 2010. Slight rise occurred in suicide rates in 2010. In 2013 the province saw 75 suicides per year. 90% - 98% of suicides are closely related to mental disease with the remaining 10% associated with different poor causes of the subject, according to bibliography. In this retrospective study, it has been found that the highest risk rests with men over 40 years of age in the central and southern part of the island. Among the forms of suicide reported, the most common is hanging followed by jumping from a height. It’s important to understand the reasons behind suicidal behavior from a psychosocial perspective, taking into account “unsafe” indicators and individual profiles. The lethal nature of a suicide attempt also depends on the form of suicide adopted and the possibility of a rescue. Specific protocols to prevent suicide should be promoted and discussed between health and social services.

Abstract:

School failure is a worrying phenomenon of the educational system that affects most sectors of the education regarding parents, teachers and students and covers education at all levels, from basic education levels to higher levels. One of the levels where there is a high incidence of this problem is in university education, where dropout rates at university are between 25% and 50% in the early formative years. Therefore, it is considered that this phenomenon of school failure and dropout must be addressed and treated from all support systems and services that merge at school, because there are many interests involved not only in the student who fails himself, but also in society in general. The objective of this survey is finding out the effects of anxiety and personal problems in ULPGC nursing students and the consequences that can bring in their academic performance. The results obtained show direct influence of variables such as attendance, studies organization, disappointment feelings, approaching dropout and others, however the hypotheses that were not met differentially, offer us relevant information, for better understanding and making decisions to prevent school failure at university.

Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.58108
Abstract:

This study shows the evolution of the demand and assistance in a municipal therapeutic service portfolio in Tenerife. It is a descriptive, qualitative and quantitative study. The sample is made up of 1175 patients assisted in this program in the period of time which ranges from 2005 to 2012. The results show the high demand of this program. Moreover, the results of the intervention coincide with those expected by international and national organisms. Most of the demand is centred on the area of problems called role transitions, followed by those problems grouped in the area of interpersonal conflicts. In the third place, the demand is centred on those problems grouped in the area of interpersonal deficits, and finally on those problems grouped in the category of grieving or mourning problems. It is extremely important to offer this program in the municipal service portfolio as a complementary resource which facilitates the prevention and approach to problems related to mental health in the community because of its high demand, effectiveness and efficacy.

Theoretical study of neutrino-induced coherent pion production off nuclei at T2K and MiniBooNE energies
Amaro, J. E.;Hernández, E.;Nieves, J.;Valverde, M.
High Energy Physics - Phenomenology , 2008, DOI: 10.1103/PhysRevD.79.013002
Abstract: We have developed a model for neutrino-induced coherent pion production off nuclei in the energy regime of interest for present and forthcoming neutrino oscillation experiments. It is based on a microscopic model for pion production off the nucleon that, besides the dominant Delta pole contribution, takes into account the effect of background terms required by chiral symmetry. Moreover, the model uses a reduced nucleon-to-Delta resonance axial coupling, which leads to coherent pion production cross sections around a factor two smaller than most of the previous theoretical estimates. In the coherent production, the main nuclear effects, namely medium corrections on the Delta propagator and the final pion distortion, are included. We have improved on previous similar models by taking into account the nucleon motion and employing a more sophisticated optical potential. As found in previous calculations the modification of the Delta self-energy inside the nuclear medium strongly reduces the cross section, while the final pion distortion mainly shifts the peak position to lower pion energies. The angular distribution profiles are not much affected by nuclear effects. Nucleon motion increases the cross section by 15% at neutrino energies of 650 MeV, while Coulomb effects on charged pions are estimated to be small. Finally, we discuss at length the deficiencies of the Rein-Sehgal pion coherent production model for neutrino energies below 2 GeV, and in particular for the MiniBooNE and T2K experiments. We also predict flux averaged cross sections for these two latter experiments and K2K.

Abstract: Ficus lyrata es una importante especie ornamental para interiores y paisajismo. Se evaluó el comportamiento de cuatro líneas transgénicas (tg) portadoras del gen P SAG12:ipt y el testigo sin transformar (wt), ante cuatro ambientes de cultivo: 1) 78 μmol·m-2·s-1 y 30 oC; 2) 42 μmol·m-2·s-1 y 27 oC; 3) 36 μmol·m-2·s-1 y 32 oC; 4) 18 μmol·m-2·s-1 y 27 oC. Se emplearon vitroplantas en potes con sustrato, cultivadas en umbráculo durante 270 días antes de ser sometidas a los tratamientos. Las líneas transgénicas presentaron menor contenido relativo de clorofila que el testigo sin transformar, pero mayor altura de planta y número de hojas. Entre las líneas transgénicas, la tg19 fue más alta, con hojas más grandes y menor número de ellas, mientras que la tg25 se mostró como una planta de porte bajo con gran cantidad de hojas peque as. En términos generales, el efecto de la expresión del transgen fue similar en todos los ambientes y consistió en incremento de la altura de las plantas y número de hojas, y reducción del contenido relativo de clorofila. Con base en el tama o de la planta, número de hojas y coloración del follaje, el ambiente 3 puede considerarse el más adecuado para el cultivo de esta especie con fines ornamentales. Ficus lyrata is an important ornamental species as interior plant and for landscaping. In the present work there was evaluated the behavior of four transgenic lines (tg) harboring the P SAG12:ipt gene and the wild type, without transforming (wt), exposed to different culture environments: 1) 78 μmol· m-2·s-1 and 30 oC; 2) 42 μmol· m-2·s-1 and 27 oC; 3) 36 μmol· m-2·s-1 and 32 oC; 4) 18 μmol· m-2·s-1 and 27 oC. Vitroplants in pots with substrate were cultivated in a shadehouse for 270 days before submitting them to the treatments. The transgenic lines had lower relative chlorophyll content than the control, but they were taller with higher leaf number. Among the transgenic lines, the tg19 was higher, with larger leaves, and fewer number of them, while the tg25 showed as a low growing plant with many small leaves. In general terms, the effect of the expression of the quimeric gene was similar in the four environments and promoted the increase of plant height and number of leaves, and reduction of chlorophyll content. Based on plant height, leaves number and coloration of the foliage, the environment 3 can be considered to be most suitable for the culture of this species for ornamental purposes.
