?Es el cansancio de la técnica un factor a tener en cuenta en las infecciones peritoneales?

Abstract: peritoneal infection is an inflammation of the peritoneal membrane usually caused by bacterial infection. the effects generated by a peritoneal infection are of vital importance for maintaining peritoneal dialysis treatment. in some of these infections, it is necessary to remove the catheter and consequently change to haemodialysis, the transfer to which represents one fifth of peritoneal infections. the causes of the failure in the dialytic technique are diverse. the aim of our study is to review the factors that may have had an influence on the incidence of peritoneal infection. it is noted that 58% are gram-positive, which means that more than half of the causing agents are saprophyte micro-organisms of the skin, 38% are gram-negative, the possible cause of which is lack of hygiene. 4% are negative culture. the time of exposure is compared to the episodes of peritoneal infection. the staff allocated to the peritoneal dialysis unit in the years studied were 2 nurses on 12-hour shifts on alternate days and a nurse who worked 15 hours per week. in 2009 staffing was reinforced with a care nurse working a 7-hour morning shift. since then learning programmes have been carried out without interruption by the same nurse in the shift agreed with the patient. better dedication to training and carryout out re-training reduces the rate of peritoneal infection as patient tiredness and boredom can be detected before a peritoneal infection appears.
Es el cansancio de la técnica un factor a tener en cuenta en las infecciones peritoneales? Is tiredness a factor to be taken into account in peritoneal infections?

Abstract: La infección peritoneal es una inflamación de la membrana peritoneal ocasionada habitualmente por una infección bacteriana. Los efectos que genera una infección peritoneal son de vital importancia para el mantenimiento en el tratamiento de diálisis peritoneal. En algunas de estas infecciones se hace necesaria la retirada del catéter y consecuentemente el cambio a la Hemodiálisis cuya trasferencia a ella representa la quinta parte de las infecciones peritoneales. Los motivos del fallo en la técnica dialítica son diversos. El objetivo de nuestro estudio es revisar los factores que han podido influir en la incidencia de la infección peritoneal. Se resalta que el 58% son Gram positivos, lo que significa que más de la mitad de los agentes causantes son microorganismos saprófitos de la piel, el 38% son Gram negativos cuya posible causa es también la falta de higiene. El 4% es cultivo negativo. Se comparan el tiempo de exposición con la de los episodios de infección peritoneal. El personal destinado en la unidad de diálisis peritoneal en los a os estudiados fueron 2 enfermeras/os de turno de 12 horas a días alternos y un enfermero de 15 horas semanales. En el 2009 la dotación se reforzó con una enfermera asistencial en turno de 7 horas ma ana. Desde ese momento los programas de aprendizaje se hacen ininterrumpidamente por una misma enfermera en el turno que se pacta con el paciente. Una mejor dedicación en el entrenamiento y la realización de reentrenos, disminuye la tasa de infección peritoneal ya que se puede detectar el cansancio y aburrimiento del paciente, antes de que aparezca una infección peritoneal.

Noncommutative resolutions of ADE fibered Calabi-Yau threefolds
Alexander Quintero Velez,Alex Boer
Mathematics , 2008, DOI: 10.1007/s00220-010-1052-5
Abstract: In this paper we construct noncommutative resolutions of a certain class of Calabi-Yau threefolds studied by F. Cachazo, S. Katz and C. Vafa. The threefolds under consideration are fibered over a complex plane with the fibers being deformed Kleinian singularities. The construction is in terms of a noncommutative algebra introduced by V. Ginzburg, which we call the "N=1 ADE quiver algebra".
Geometric Analogy and Products of Vectors in n Dimensions  [PDF]
Leonardo Simal Moreira
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2013, DOI: 10.4236/alamt.2013.31001
Abstract:

The cross product in Euclidean space IR3 is an operation in which two vectors are associated to generate a third vector, also in space IR3. This product can be studied rewriting its basic equations in a matrix structure, more specifically in terms of determinants. Such a structure allows extending, for analogy, the ideas of the cross product for a type of the product of vectors in higher dimensions, through the systematic increase of the number of rows and columns in determinants that constitute the equations. So, in a n-dimensional space with Euclidean norm, we can associate n – 1 vectors and to obtain an n-th vector, with the same geometric characteristics of the product in three dimensions. This kind of operation is also a geometric interpretation of the product defined by Eckman [1]. The same analogies are also useful in the verification of algebraic properties of such products, based on known properties of determinants.

On the Rotation of a Vector Field in a Four-Dimensional Space  [PDF]
Leonardo Simal Moreira
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.51015
Abstract:

Recently I published a paper in the journal ALAMT (Advances in Linear Algebra & Matrix Theory) and explored the possibility of obtaining products of vectors in dimensions higher than three [1]. In continuation to this work, it is proposed to develop, through dimensional analogy, a vector field with notation and properties analogous to the curl, in this case applied to the space IR4. One can see how the similarities are obvious in relation to the algebraic properties and the geometric structures, if the rotations are compared in spaces of three and four dimensions.

Identification of Paracoccidioides brasiliensis in adrenal glands biopsies of two patients with paracoccidioidomycosis and adrenal insufficiency

Revista do Instituto de Medicina Tropical de S?o Paulo , 2009, DOI: 10.1590/S0036-46652009000100008
Abstract: the authors report two cases of adrenal insufficiency secondary to infiltration of the adrenal glands by paracoccidioides brasiliensis. the first patient had been treated for a chronic multifocal form of paracoccidiodomycosis 11 years ago. the diagnosis of the mycosis was done simultaneous with that of the adrenal insufficiency in the second patient. in both patients the diagnosis was done by direct visualization of fungus in adrenal biopsies. they were treated with hormonal supplements and itraconazol by 12 and six months, without relapses during the follow-up period.
