Abstract: reoperation is the method of choice for correction of prosthetic paravalvular leaks. the percutaneous repair of mitral paravalvular leaks might represent an interesting alternative for selected cases. we report two cases of mitral paravalvular leaks treated with amplatzertm vascular plug iii guided by three-dimensional transesophageal echocardiography using the percutaneous approach. the first case was of a 55-year old male who had undergone five previous cardiac surgeries (aortic and mitral valve replacements) and evolved with new york heart association (nyha) class iii heart failure and severe mitral regurgitation. the second case was of a 76-year old male previously submitted to aortic valve replacement twice, the last one associated to mitral valve replacement, which evolved with nyha class iv heart failure and severe mitral regurgitation, and had several comorbidities increasing surgical risk. the procedures were performed percutaneously under general anesthesia using the transeptal approach to deploy the plugs, which occluded the paravalvular defects successfully in both cases.

Abstract: the objective of this work was to evaluate the effects of tambacu vitamin e dietary supplementation on performance and hematological variables, and determine the relationship of glutathione peroxidase activity with vitamin e and selenium suplementation. two hundred and fifty juvenile tambacus were used, divided into 25 aquaria. the basal diet was pelleted with 32% of crude protein and 3,300 kcal kg-1 of digestible energy, with 0.40 mg kg-1 se. test diets - isoproteic and isocaloric - were composed of the basal diet with increasing vitamin e concentrations (0, 100, 200, 300, 400 mg kg-1), in a completely randomized design, with five treatments and five replications. no significant effect of vitamin e supplementation was observed on total length, mean corpuscular volume, mean corpuscular hemoglobin concentration and total erythrocyte, and on the enzymatic activity of glutathione peroxidase. however, final weight and apparent feed conversion were significantly affected by supplemented treatments. standard length and weight gain improved using diets supplemented with 400 mg kg-1 of vitamin e. dietary vitamin e supplementation results in better tambacu performance.
El primer equipo interdisciplinario de Costa Rica

Medicina Legal de Costa Rica , 2008,
Abstract: sexual abuse is series of actitudes of a subject, which he realize in detriment of other, usually younger, for his self satisfaction. the statistics of differents countries shows that this issue is torning into epidemics amounts ant its suffocating us. prevention in revictimation is a policy established in costa rica for over a decade and for this we has had form interdisciplinary teams. in early times those temas had a lot of uncompatible disciplines soch as team is formed by only three members: the forensic doctor, the psychologist and the social worker, ehom attent to a weekly metting to analize the different conclusions of each especiallist. actually there are teams established in almost all head of province in our country with percial function well established in the legal treatment of the causes of these crimes.

Abstract: El abuso sexual es un conjunto de actitudes de un sujeto que realiza en detrimento de otro, generalmente menor, para su autosatisfacción. Las estadísticas de los diferentes países apuntan a que se está convirtiendo en una epidemia que nos está asfixiando. La prevención de la revictimización, una política establecida en el Poder Judicial de Costa Rica desde hace más de diez a os, dio como fruto la conformación de los equipos interdisciplinarios. Al inicio, estos abarcaron una serie de disciplinas tan disímiles entre sí, que comprendían tanto el derecho, como la medicina, la psicología, el trabajo social y la psiquiatría. Con el paso de los a os los equipos se fueron reduciendo hasta quedar conformados por el psicólogo, el trabajador social y el médico forense, que asiste a una reunión semanal con ellos y en donde se discuten las diferentes conclusiones de las tres disciplinas. Hoy en día son equipos establecidos prácticamente en todas las cabeceras de provincia de nuestro país con funciones periciales muy específicas en el tratamiento legal de las causas de los delitos sexuales.

Real-time reverse-transcription PCR in the diagnosis of influenza A (H1N1)v in intensive care unit adult patients
Concepción Gimeno, David Navarro
Critical Care , 2009, DOI: 10.1186/cc8164
Abstract: The authors found that real-time RT-PCR for novel influenza A (H1N1)v virus in nasopharyngeal swabs on intensive care unit (ICU) admission was negative in four patients (12.5%) who later had a positive PCR result in respiratory secretions obtained at intubation, and concluded that 'a negative PCR result at admission should not exclude influenza A (H1N1)v due to the presence of false negative results in at least 10% cases' [1]. We of course understand what the authors meant. In our opinion, however, this assumption is formally inaccurate, and is somewhat misleading, as it might be inferred that real-time RT-PCR gives at least 10% of false negative results in patients with overt symptomatic influenza requiring ICU admission.The negative results reported by the authors cannot be considered true false negative RT-PCR results, as samples were not tested in parallel by a different assay yielding a positive result - in fact, RT-PCR, which was used at participating centers, is currently the standard method for the diagnosis of influenza. Optimal sensitivity of RT-PCR and rapid antigen tests is achieved when upper tract respiratory specimens are collected within the first few days after the onset of symptoms, as appeared to be the case for the above-mentioned patients. Inappropriate sampling or specimen processing or suboptimal sensitivity of the PCR assay used most probably accounted for the negative results. No speculation on this matter can be made because the microbiological information given to the readers was rather scarce.The possibility of false negative RT-PCR results for influenza A (H1N1)v in severely ill patients requiring admission to ICUs is a very important issue that must be further investigated.Alejandro Rodríguez, Josep-Maria Sirvent, Lorenzo Socias, Sergio Martínez-Cuéllar and Jordi Rello, for the H1N1 SEMICYUC Working GroupWe are grateful to Gimeno and Navarro, since this allows us to clarify diagnosis in intubated patients.We reported that one out of six
VERIFICACIóN EMPíRICA DE LA CURVA DE LAFFER EN LA ECONOMíA COLOMBIANA (1980-2005)
BEJARANO NAVARRO,HéCTOR DAVID;
Revista Facultad de Ciencias Económicas: Investigación y Reflexión , 2008,
Abstract: tributary reforms carried out in colombia have aimed at increasing tributary incomes to guarantee the balance of short and mediumterm public finances. though such reforms succeeded in increasing tributary incomes, their effects were mainly transitory leading to the implementation of new reforms. based on laffer's curve, this paper presents empirically that regardless the increase of domestic taxes in colombia, tax collection has decreased. this paper also attempts to prove that colombia generates lower incomes in spite of today's current tax collection and behavior.
ARCHITECTURE DEGREE PROJECT: USE OF 3D TECHNOLOGY, MODELS AND AUGMENTED REALITY EXPERIENCE WITH VISUALLY IMPAIRED USERS
Isidro Navarro Delgado,David Fonseca
Journal of Systemics, Cybernetics and Informatics , 2012,
Abstract: Web 3.0 technologies provide effective tools for interpreting architecture and culture in general. Thus, a project may have an emotional impact on people while also having a more widespread effect in society as a whole. This project defines a methodology for evaluating accessibility of architecture for people with visual disabilities and the application of this to visiting emblematic buildings such as the Basilica of the Holly Family in Barcelona, designed by the architect, Antoni Gaudí.
On a class of elliptic systems in RN
David G. Costa
Electronic Journal of Differential Equations , 1994,
Abstract: $Bbb R^N$ of the form $$ left{ Begin{array}{c} - Delta u + a(x) u = F_u(x,u,v) - Delta v + b(x) v = F_v(x,u,v) ,, end{array} ight. $$ where $a,b:Bbb R^N ightarrow Bbb R$ are continuous functions which are coercive; i.e., $a(x)$ and $b(x)$ approach plus infinity as $x$ approaches plus infinity. Under appropriate growth and regularity conditions on the nonlinearities $F_u(.)$ and $F_v(.)$, the (weak) solutions are precisely the critical points of a related functional defined on a Hilbert space of functions $u,v$ in $H^1(Bbb R^N)$.
Faster deterministic integer factorization
Edgar Costa,David Harvey
Computer Science , 2012,
Abstract: The best known unconditional deterministic complexity bound for computing the prime factorization of an integer N is O(M_int(N^(1/4) log N)), where M_int(k) denotes the cost of multiplying k-bit integers. This result is due to Bostan--Gaudry--Schost, following the Pollard--Strassen approach. We show that this bound can be improved by a factor of (log log N)^(1/2).
