Use of Granada medium to detect group B streptococcal colonization in pregnant women.

Direct inoculation onto Granada medium (GM) in plates and tubes was compared to inoculation into a selective Todd-Hewitt broth (with 8 microg of gentamicin per ml and 15 microg of nalidixic acid per ml) for detection of group B streptococci (GBS) in pregnant women with 800 vaginal and 450 vaginoanorectal samples. Comparatively, GM was found to be as sensitive as the selective broth for the detection of GBS in vaginal specimens and more sensitive than selective broth for the detection of GBS in vaginoanorectal samples (96 versus 82%). The use of GM improved the time to reporting of a GBS-positive result by at least 24 h and reduced the direct cost of screening. We have also found that the inconvenience of anaerobic incubation of GM plates can be avoided when a cover slide is placed upon the inoculum, because aerobic incubation in GM plates with cover slides causes GBS to develop the same pigmentation that it develops with incubation under anaerobic conditions. These data support the routine use of GM plates or tubes as a more accurate, easier, and cheaper method of identification of GBS-colonized women compared to the enrichment broth technique.

New Granada Medium for detection and identification of group B streptococci.

A methotrexate-containing medium for the detection of beta-hemolytic group B streptococci from clinical specimens on the basis of detection of pigment is described. The medium contained peptone, starch, serum, MgSO4, glucose, pyruvate, methotrexate (as pigment enhancer), phosphate-morpholine-propanesulfonic acid buffer, and selective agents. The recovery of beta-hemolytic group B streptococci was comparable to that obtained with selective broth.

Efectividad comparativa del seguimiento remoto a personas con marcapasos cardíacos frente al convencional: calidad de vida a los 6 meses.

BACKGROUND The use of remote follow-up (RF) of people with pacemakers (PM) is limited in comparison to the hospital modality (HS), being still poor the scientific evidence that shows their comparative effectiveness. The aim of this study was to compare the quality of life in individuals with different modalities of follow-up. METHODS Controlled, not randomized nor masked clinical trial, with data collection at pre and post-implantation of pacemakers during the 6 months follow-up. All patients over 18 years-old who were implanted a PM during the study period were selected (n = 83), and they were assigned to RF (n = 30) or HF (n = 53) groups according to their personal characteristics and patient's preferences. Baseline characteristics and number of visits to the hospital were analysed, the EuroQol-5D (EQ5D) questionnaire was administered to evaluate the health-related quality of life, and Duke Activity Status Index (DASI) to assess the functional capacity. RESULTS There were no significant differences between both groups in relation to the baseline analysis, EQ5D (RF:0.7299; HF:0.6769) and DASI (RF:21.41; HF:19.99). At 6 months the quality of life was improved in both groups (EQ5D RF:0.8613; HF:0.8175; p = 0,439) still without significant differences between them. DASI score was similar to baseline (20.51 vs 21.80). RF group performed less transmissions/visits per patient (1.57) than hospital group (1.96; relative reduction 31%; p = 0.015). CONCLUSIONS Remote follow-up of people with pacemakers might be considered as an equivalent option to the hospital follow-up in relation to the quality of life and it reduces the number of hospital visits.

Diagnostic yield of a PCR assay in focal complications of brucellosis.

In order to evaluate the diagnostic yield of a PCR assay for patients with focal complications of brucellosis, we studied by PCR and by conventional microbiological techniques 34 nonblood samples from 32 patients with different focal forms of brucellosis. The samples from patients with brucellosis were paired to an equal number of control samples from the same locations of patients whose illnesses had different etiologies. Thirty-three of the 34 nonblood samples (97%) from the brucellosis patients were positive by PCR, whereas Brucella spp. were isolated from only 29.4% of the conventional cultures. For 11.4% of the patients, the confirmatory serological tests were either negative or showed titers below the diagnostic range. Two patients (6.2%) from the control group, both with tuberculous vertebral osteomyelitis, had a positive PCR result. The brucella PCR of blood from these two patients was also positive, and the two strains of Mycobacterium tuberculosis isolated were analyzed by the brucella PCR, with no evidence of amplification. These results show that the PCR assay is far more sensitive than conventional cultures, and this, coupled with its speed and reduction in risk to laboratory workers, makes this technique a very useful tool for the diagnosis of focal complications of brucellosis.

Intervenció per millorar la comunicació dels nens i adolescents amb DAR i els seus pares : Aplicació pel programa d'intervenció online DARWeb

Chronic pain is a relevant problem in our society. Concerning the young population, recurring abdominal pain (RAP in English, DAR in Spanish and Catalan) is very common among children and adolescents. DARWeb is an online treatment program addressed to children and teenagers with DAR and their parents. This work is aimed to develop an intervention to improve the communication skills of the children/adolescents with DAR and their parents. It is also proposed how this could be implemented to DARWeb.

Aterosclerosis cérvico-cerebral subclínica: evaluación del índice REGICOR, el grosor íntima-media y el índice tobillo-brazo en la detección de sujetos en riesgo en la población

La aterosclerosis cérvico-cerebral es una de las principales causas de ictus isquémico, y por tanto, de morbimortalidad en nuestro medio. La detección de la misma en su fase asintomática mediante instrumentos como la función REGICOR, el grosor íntima-media y el índice tobillo-brazo podría mejorar las estrategias de prevención primaria. Comprobamos que, en nuestra cohorte de 933 sujetos sin antecedentes cardiovasculares, los tres factores (REGICOR≥10, GIM≥0.9, ITB≤ 0.9) se asociaron de forma independiente con la presencia de aterosclerosis cérvico-cerebral y de cualquier localización (extracraneal-intracraneal-combinada). La utilización conjunta de REGICOR e ITB podría facilitar el diagnóstico precoz de la aterosclerosis cérvico-cerebral subclínica.

Implementació d'un instrument de mesura de la qualitat del servei d'un supermercat online

Aquest treball posa en pràctica l'adaptació d'una enquesta anomenada E-S-QUAL, que avalua la qualitat del servei en establiments virtuals. Es parteix de la tesi del doctor Cristóbal i es combina amb part de la tesi del doctor Granollers, concretament amb el model MPIU+Q. S'ha implementat un lloc web amb l'enquesta, ens hem posat en contacte amb un supermercat virtual (Plusfresh.com)i l'hem posada en maxa per a que els clients la contestessin. Finalment, s'ha fet una anàlisi de les dades recollides i s'han extret uns informes i conclusions.

Adaptación de la aplicación para la realización de Card Storing para dotarla de elementos multimedia y capacidad de distribución online

Este proyecto surge de la necesidad de mejorar un CardStoring ya existente de forma que, mediante un servidor, podamos usarlo de forma remota, y poder separar la aplicación en dos partes; ya que hasta el momento se encontraba en una sola. Con esto se consigue que la creación de las tarjetas pase desapercibida para el usuario y que a éste le resulte más simple el uso de esta aplicación. Con esto, se lograría que la aplicación pueda ser distribuida de forma Web. También será modificado el tipo de tarjetas para poder introducir sonidos, videos e imágenes. Con lo cual conseguimos adaptar el proyecto a personas discapacitadas como pueden ser sordos e invidentes además de aportar un uso más amplio a cada una de las tarjetas.

Speed of reaction-diffusion fronts in spatially heterogeneous media

The front speed problem for nonuniform reaction rate and diffusion coefficient is studied by using singular perturbation analysis, the geometric approach of Hamilton-Jacobi dynamics, and the local speed approach. Exact and perturbed expressions for the front speed are obtained in the limit of large times. For linear and fractal heterogeneities, the analytic results have been compared with numerical results exhibiting a good agreement. Finally we reach a general expression for the speed of the front in the case of smooth and weak heterogeneities
