BACKGROUND In 1997, 18.5% of the cases of Meningococcal Disease caused b serogroup C in Andalusia were children between 2 and 4 years of age; ages where the initial immune response and the duration of the capsular A + C meningococcal polysaccharide vaccine is less than in older age groups. Research was designed in order to measure the immune response produced by this vaccine in children from 2 to 6 years of age and to compare it with the natural immunity present in unvaccinated children. METHODS I. Dual monitoring study: a) groups of children vaccinated previously and control groups, b) groups of children who were going to be vaccinated, for pre and post-vaccination (1, 6 and 12 months) analysis and a control group. II. The bactericidal activity was measured according to the standardised protocol of the CDC with regard to the strain of N. meningitidis C-11. The sera with bactericidal activity (TAB) > 1:8 were considered to be protective. RESULTS 1 and 2 months following vaccination, the proportion of TAB > 1:8 was significantly higher than that of the control group (65.6% and 73% in comparison to 2.2% and 12%). In the pre-vaccine and post-vaccine (after 6, 7, 12 and 13 months) verification, no significant difference between vaccinated individuals and controls was observed. CONCLUSIONS The differences between vaccinated and unvaccinated individuals 1 and 2 months following vaccination indicate seroconversion in the vaccinated individuals. For the age group of between 2 to 6 years of age, the bactericidal activity acquired decline quickly, as, after 6 months, differences between this group and the control group are no longer observed.

We report the case of a patient receiving subcutaneous methotrexate (MTX) treatment for rheumatoid arthritis (RA) who developed a complex pattern of neurological and pulmonary symptoms. Fluctuant dysarthria, magnetic gait, weakness and dysmetria of the lower limbs, as well as symptoms and signs consistent with a diagnosis of pneumonitis started within 6 weeks of initiating MTX treatment and slowly resolved after its discontinuation. This case highlights the fact that even the relatively low doses of MTX in the therapy of RA can produce neurotoxicity, which can become manifest in a broad range of symptoms.

Aquest treball presenta un model comparatiu d’anàlisis de la marca en base a l’inconscient col•lectiu, teoria desenvolupada per C. G. Jung (1991), adequat per Sabrine Dornelles (2010) a l’estudi de les marques comercials i contrastat en aquest treball amb la proposta d’aproximació al Perfil Arquetípic Azteca. Per aquesta raó, s’ha realitzat una revisió bibliográfica en referencia a l’objecte de l’estudi del posicionament de la marca, i en especial, dels atributs vinculats al perfil azteca. Amb l’objectiu de conèixer si la cultura influeix o no, en la percepció d’una marca, s’ha realitzat un pre-test via online amb subjectes de nacionalitat espanyola i de països d’Amèrica llatina (Argentina, Colòmbia, Equador, Perú, República Dominicana i Veneçuela) per al grup de control. 5 Els resultats han sigut tractats tant a nivell d’estadística descriptiva com a mode inferencial. Les dades amb significació p≤ 0,05 mostren els estímuls (atributs) que foren associats o no, amb la marca del país Mèxic. Mentre que l’arquetip occidental (grec) va permetre en major percentatge valorar la marca amb tots els subjectes (espanyols, mexicans i llatins) l’arquetip prehispànic no dóna significació suficient amb els espanyols i llatins, però en canvi aporta matisos en el cas dels mexicans. En referència a l’esmenta’t anteriorment , cal que el proper pas sigui millorar el perfil d’arquetipus azteca.

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.
