Infeccions del sistema nerviós central pel virus varicel.la-zoster

Una associació inusual de casos d’infecció del SNC pel VVZ en un periode de 16 mesos i l’absència de lesions cutànies en la majoria d’ells ens va portar a revisar els casos d’infecció del SNC pel VVZ al nostre centre en els darrers 6 anys. Hem trobat 5 meningitis, 5 encefalitis i 2 mielitis. Les meningitis afecten a joves no immunodeprimits i solen cursar sense lesions d’herpes zòster. A més, sovint cursen amb hipoglucorràquia, el que inicialment pot fer pensar en una meningitis aguda bacteriana. Les encefalitis afecten a pacients més grans, immunodeprimits i s’acompanyen de lesions d’herpes zòster.

Prospective registry of symptomatic severe aortic stenosis in octogenarians: a need for intervention.

OBJECTIVE To study the factors associated with choice of therapy and prognosis in octogenarians with severe symptomatic aortic stenosis (AS). STUDY DESIGN Prospective, observational, multicenter registry. Centralized follow-up included survival status and, if possible, mode of death and Katz index. SETTING Transnational registry in Spain. SUBJECTS We included 928 patients aged ≥80 years with severe symptomatic AS. INTERVENTIONS Aortic-valve replacement (AVR), transcatheter aortic-valve implantation (TAVI) or conservative therapy. MAIN OUTCOME MEASURES All-cause death. RESULTS Mean age was 84.2 ± 3.5 years, and only 49.0% were independent (Katz index A). The most frequent planned management was conservative therapy in 423 (46%) patients, followed by TAVI in 261 (28%) and AVR in 244 (26%). The main reason against recommending AVR in 684 patients was high surgical risk [322 (47.1%)], other medical motives [193 (28.2%)], patient refusal [134 (19.6%)] and family refusal in the case of incompetent patients [35 (5.1%)]. The mean time from treatment decision to AVR was 4.8 ± 4.6 months and to TAVI 2.1 ± 3.2 months, P < 0.001. During follow-up (11.2-38.9 months), 357 patients (38.5%) died. Survival rates at 6, 12, 18 and 24 months were 81.8%, 72.6%, 64.1% and 57.3%, respectively. Planned intervention, adjusted for multiple propensity score, was associated with lower mortality when compared with planned conservative treatment: TAVI Hazard ratio (HR) 0.68 (95% confidence interval [CI] 0.49-0.93; P = 0.016) and AVR HR 0.56 (95% CI 0.39-0.8; P = 0.002). CONCLUSION Octogenarians with symptomatic severe AS are frequently managed conservatively. Planned conservative management is associated with a poor prognosis.

Etravirine Concentrations in Cerebrospinal Fluid in HIV-Infected Patients

Cerebrospinal fluid Etravirine concentrations were measured in 12 asymptomatic HIV-infected patients. Median ETR concentration in plasma was 611.5 ng/mL (148-991) and median CSF ETR concentration was 7.24 ng/ml (3.5-17.9). In all cases Etravirine levels were above the IC50 range(0.39-2.4ng/ml) and CSF viral load was &40 copies/ml in all patients with undetectable plasma viral load. Our data suggest that ETR achieves concentrations several times above the IC50 range in CSF. All patients with undetectable plasma viral load were virologically suppressed in CSF while receiving an ETR-containing regimen. ETR may help in controlling HIV-1 in CNS.

Epidemiologia de la fractura a l’atenció primària de catalunya

Utilitzant una base de dades amb informació clínica extreta de l’historial d’Atenció Primària (AP) a Catalunya, hem portat a terme un estudi de cohorts retrospectiu l’any 2009, incloent individus  50 anys. Hem identificat les fractures osteoporòtiques majors utilitzant codis CIE-10. 2.011.430 individus van ser inclosos. La incidència total va ser de 10’91/1.000 persones-any. La fractura més freqüent entre les dones va ser la d’avantbraç i entre els homes la vertebral simptomàtica. Totes les fractures van augmentar amb l’edat però es van observar diferents patrons segons localització. Aquesta informació és rellevant per la planificació dels serveis d’AP al nostre país.

Genomic acute myeloid leukemia-associated inv(16)(p13q22) breakpoints are tightly clustered.

The inv(16) and related t(16;16) are found in 10% of all cases with de novo acute myeloid leukemia. In these rearrangements the core binding factor beta (CBFB) gene on 16q22 is fused to the smooth muscle myosin heavy chain gene (MYH11) on 16p13. To gain insight into the mechanisms causing the inv(16) we have analysed 24 genomic CBFB-MYH11 breakpoints. All breakpoints in CBFB are located in a 15-Kb intron. More than 50% of the sequenced 6.2 Kb of this intron consists of human repetitive elements. Twenty-one of the 24 breakpoints in MYH11 are located in a 370-bp intron. The remaining three breakpoints in MYH11 are located more upstream. The localization of three breakpoints adjacent to a V(D)J recombinase signal sequence in MYH11 suggests a V(D)J recombinase-mediated rearrangement in these cases. V(D)J recombinase-associated characteristics (small nucleotide deletions and insertions of random nucleotides) were detected in six other cases. CBFB and MYH11 duplications were detected in four of six cases tested.

Bedeutung der Spitalentschädigung nach Patientengruppen für Managed Care

Das Patientenklassifikationssystem AP-DRG wurde im Juli 2001 in einem Zürcher Spital und im Jahr 2002 in den Waadtländer Spitälern und in einem zweiten Zürcher Spital eingeführt. Die AP-DRGs (All Patients Diagnosis Related Groups) sind in erster Linie ein nützliches Messinstrument für die Finanzierung, die Planung und das Management der Spitäler, aber sie können sich auch als ernorm hilfreich erweisen für die Risikoeinschätzung sowie für Managed-Care-Programme.<Managed Care> [Article original en français] AP-DRG, quel intérêt pour le Managed Care? / L.

Estrategia de reducción de costes en la artroplastia total de rodilla

Aim: Assess the clinical utility of plain radiography in the first postoperative outpatient visit after total knee arthroplasty. Patients and Methods: 200 patients which underwent a total knee arthroplasty from January to May 2012 were analyzed retrospectively, they had two previous control radiographs at hospital discharge and two more at 4-6 weeks after surgery, which were compared, seeking for radiographics signs that would induce a therapeutic changes in the patient’s clinical course. Results: No radiographics signs were observed in the cases studied in the first postoperative visit one month after the surgery, consequently the patient’s treatment plan had no change. Discussion: Our results support those of other authors who have recognized the benefits of reducing the number of postoperative radiographs, improve the cost effectiveness of outpatients care and avoid an extra damage to the patient’s health. We believe that repeated use of serial radiographs in outpatient is simply a custom that has become law, to calm down the patient, and his surgeon, with no scientific evidence to support it use. Conclusions: Our results suggest that the plain AP and L radiographic projection at the first visit, one month later after a TKA, does not provide any clinic information, adds substantial cost to the heath-care system and unnecessary harms the patient.

Predicting response and survival in chemotherapy-treated triple-negative breast cancer.

BACKGROUND In this study, we evaluated the ability of gene expression profiles to predict chemotherapy response and survival in triple-negative breast cancer (TNBC). METHODS Gene expression and clinical-pathological data were evaluated in five independent cohorts, including three randomised clinical trials for a total of 1055 patients with TNBC, basal-like disease (BLBC) or both. Previously defined intrinsic molecular subtype and a proliferation signature were determined and tested. Each signature was tested using multivariable logistic regression models (for pCR (pathological complete response)) and Cox models (for survival). Within TNBC, interactions between each signature and the basal-like subtype (vs other subtypes) for predicting either pCR or survival were investigated. RESULTS Within TNBC, all intrinsic subtypes were identified but BLBC predominated (55-81%). Significant associations between genomic signatures and response and survival after chemotherapy were only identified within BLBC and not within TNBC as a whole. In particular, high expression of a previously identified proliferation signature, or low expression of the luminal A signature, was found independently associated with pCR and improved survival following chemotherapy across different cohorts. Significant interaction tests were only obtained between each signature and the BLBC subtype for prediction of chemotherapy response or survival. CONCLUSIONS The proliferation signature predicts response and improved survival after chemotherapy, but only within BLBC. This highlights the clinical implications of TNBC heterogeneity, and suggests that future clinical trials focused on this phenotypic subtype should consider stratifying patients as having BLBC or not.

Impact of Balanced or Unbalanced Karyotype At Diagnosis On Prognosis of CML: Long-Term Observation From 1346 Patients of the Randomized CML Study IV

Introduction: Acquired genetic instability in chronic myeloid leukemia (CML) as a consequence of the translocation t(9;22)(q34;q11) and the resulting BCR-ABL fusion causes the continuous acquisition of additional chromosomal aberrations and mutations and thereby progression to accelerated phase (AP) and blast crisis (BC). At least 10% of patients in chronic phase (CP) CML show additional alterations at diagnosis. This proportion rises during the course of the disease up to 80% in BC. Acquisition of chromosomal changes during treatment is considered as a poor prognostic indicator, whereas the impact of chromosomal aberrations at diagnosis depends on their type. Patients with major route additional chromosomal alterations (major ACA: +8, i(17)(q10), +19, +der(22)t(9;22)(q34;q11) have a worse outcome whereas patients with minor route ACA show no difference in overall survival (OS) and progression-free survival (PFS) compared to patients with the standard translocation, a variant translocation or the loss of the Y chromosome (Fabarius et al., Blood 2011). However, the impact of balanced vs. unbalanced (gains or losses of chromosomes or chromosomal material) karyotypes at diagnosis on prognosis of CML is not clear yet. Patients and methods: Clinical and cytogenetic data of 1346 evaluable out of 1544 patients with Philadelphia and BCR-ABL positive CP CML randomized until December 2011 to the German CML-Study IV, a randomized 5-arm trial to optimize imatinib therapy by combination, or dose escalation and stem cell transplantation were investigated. There were 540 females (40%) and 806 males (60%). Median age was 53 years (range, 16-88). The impact of additional cytogenetic aberrations in combination with an unbalanced or balanced karyotype at diagnosis on time to complete cytogenetic and major molecular remission (CCR, MMR), PFS and OS was investigated. Results: At diagnosis 1174/1346 patients (87%) had the standard t(9;22)(q34;q11) only and 75 patients (6%) had a variant t(v;22). In 64 of 75 patients with t(v;22), only one further chromosome was involved in the translocation; In 8 patients two, in 2 patients three, and in one patient four further chromosomes were involved. Ninety seven patients (7%) had additional cytogenetic aberrations. Of these, 44 patients (3%) lacked the Y chromosome (-Y) and 53 patients (4%) had major or minor ACA. Thirty six of the 53 patients (2.7%) had an unbalanced karyotype (including all patients with major route ACA and patients with other unbalanced alterations like -X, del(1)(q21), del(5)(q11q14), +10, t(15;17)(p10;p10), -21), and 17 (1.3%) a balanced karyotype with reciprocal translocations [e.g. t(1;21); t(2;16); t(3;12); t(4;6); t(5;8); t(15;20)]. After a median observation time of 5.6 years for patients with t(9;22), t(v;22), -Y, balanced and unbalanced karyotype with ACA median times to CCR were 1.05, 1.05, 1.03, 2.58 and 1.51 years, to MMR 1.31, 1.51, 1.65, 2.97 and 2.07 years. Time to CCR and MMR was longer in patients with balanced karyotypes (data statistically not significant). 5-year PFS was 89%, 78%, 87%, 94% and 69% and 5-year OS 91%, 87%, 89%, 100% and 73%, respectively. In CML patients with unbalanced karyotype PFS (p<0.001) and OS (p<0.001) were shorter than in patients with standard translocation (or balanced karyotype; p<0.04 and p<0.07, respectively). Conclusion: We conclude that the prognostic impact of additional cytogenetic alterations at diagnosis of CML is heterogeneous and consideration of their types may be important. Not only patients with major route ACA at diagnosis of CML but also patients with unbalanced karyotypes identify a group of patients with shorter PFS and OS as compared to all other patients. Therefore, different therapeutic options such as intensive therapy with the most potent tyrosine kinase inhibitors or stem cell transplantation are required.

IVA in addition to BMD can change the osteoporosis management in 25% of clinical routine patients

Introduction Vertebral fracture is one of the major osteoporoticfractures which are unfortunately very often undetected. In addition,it is well known that prevalent vertebral fracture increases dramaticallythe risk of future additional fracture. Instant Vertebral Assessment(IVA) has been introduced in DXA device a couple of years ago toease the detection of such fracture when routine DXA are performed.To correctly use such tool, ISCD provided clinical recommendationon when and how to use it. The aim of our study was to evaluate theISCD guidelines in clinical routine patients and see how often itmay change of patient management.Methods During two months (March and April 2010), a medicalquestionnaire was systematically given to our clinical routine patientto check the validity of ISCD IVA recommendations in our population.In addition, all women had BMD measurement at AP spine,femur and 1/3 radius using a Discovery A System (Hologic, Waltham,USA). When appropriate, IVA measurement had been performedon the same DXA system and had been centrally evaluated by twotrained doctors for fracture status according to the semi-quantitativemethod of Genant. The reading had been performed when possiblebetween L5 and T4.Results Out of 210 women seen in the consultation, 109 (52 %)of them (mean age 68.2 ± 11.5 years) fulfilled the necessary criteriato have an IVA measurement. Out of these 109 women, 43 (incidence39.4 %) had osteoporosis at one of the three skeletal sitesand 31 (incidence 28.4 %) had at least one vertebral fracture. 14.7 %of women had both osteoporosis and at least one vertebral fractureclassifying them as "severe osteoporosis" while 46.8 % did not haveosteoporosis and no vertebral fracture. 24.8 % of the women hadosteoporosis but no vertebral fracture while 13.8 % of women didhave osteoporosis but vertebral fracture (clinical osteoporosis).Conclusions In 52 % of our patients, IVA was needed accordingto ISCD criteria. In half of them the IVA test influenced of patientmanagement either may changing the type of treatment of simplyby classifying patient as "clinical osteoporosis". IVA appears to bean important tool in clinical routine but unfortunately is not yetvery often use in most of the centers.

Analysis and Design of a secure WLAN solution for Cobre Las Cruces

Cobre Las Cruces is a renowned copper mining company located in Sevilla, with unexpected problems in wireless communications that have a direct affectation in production. Therefore, the main goals are to improve the WiFi infrastructure, to secure it and to detect and prevent from attacks and from the installation of rogue (and non-authorized) APs. All of that integrated with the current ICT infrastructure.This project has been divided into four phases, although only two of them have been included into the TFC; they are the analysis of the current situation and the design of a WLAN solution.Once the analysis part was finished, some weaknesses were detected. Subjects such as lack of connectivity and control, ignorance about installed WiFi devices and their localization and state and, by and large, the use of weak security mechanisms were some of the problems found. Additionally, due to the fact that the working area became larger and new WiFi infrastructures were added, the first phase took more time than expected.As a result of the detailed analysis, some goals were defined to solve and it was designed a centralized approach able to cope with them. A solution based on 802.11i and 802.1x protocols, digital certificates, a probe system running as IDS/IPS and ligthweight APs in conjunction with a Wireless LAN Controller are the main features.

Factor de riesgo cardiovascular en el trastorno mental severo

Antecedentes: Existe la percepción de que los pacientes con trastorno mental severo (TMS) presentan una mayor prevalencia de factores de riesgo cardiovascular (FRCV) y un menor control de los mismos en comparación con la población general. Objetivos: Conocer la prevalencia de los FRCV y hábitos tóxicos en pacientes con TMS y evaluar el seguimiento por la Atención Primaria (AP) en los que presentan un riesgo vascular elevado. Diseño y metodología: Se realizó un estudio descriptivo de prevalencia y de seguimiento en una muestra representativa de los pacientes con diagnóstico de TMS seguidos en el Centro de salud mental de Mataró. Se registraron los parámetros antropométricos, los FRCV, hábitos tóxicos, perfil lipídico y tratamientos farmacológicos. Se calculó el RCV mediante las tablas de REGICOR. Los pacientes con un RCV & 10% fueron derivados a AP para valorar la estrategia terapéutica. Se evaluó el seguimiento por parte de los especialistas a los 4 meses y en Atención Primaria a los 6-9 meses. Resultados: Se realizaron 112 entrevistas en el centro de Salud Mental de Mataró; 62% eran hombres y 38% mujeres, con una edad media de 43 ± 11,9 años. La obesidad abdominal fue el FRCV más prevalente (62%), le siguió el tabaquismo en un 58,9%, el sedentarismo con un 48,2% y la dislipemia 42%. El 66,8% de los pacientes eran portadores de tratamiento con antipsicóticos atípicos, lo que se asocia con un mayor RCV. Un total de 102 pacientes (91% de la muestra) presentaban uno o más FRCV, 98 de los mismos tenían un RCV & 10 y 4 presentaron un RCV & 10. Se derivaron 6 pacientes a la AP para control de los FRCV, de los que 3 nunca habían sido atendidos en AP. A los 9 meses fueron visitados el 50% de los derivados a AP, y se consiguió reducir el RCV & 10 en un 50% de los que se le hizo la recomendación de seguimiento. Conclusión: Los pacientes con TMS acuden habitualmente a las consultas de AP para el control de los FRCV. La prevalencia de FRCV en pacientes con TMS es superior a la población general. El porcentaje de pacientes con RCV elevado según el REGICOR es bajo.
