Leucemias agudas secundarias a tratamiento con quimioterapia y/o radioterapia: estudio de 23 pacientes en un solo centro.

L’ús d’agents citotòxics ha incrementat la incidència de leucèmies agudes secundàries (LAS). De 23 LAS diagnosticades en 20 anys, s’analitzaren els agents citotòxics, caraterístiques clínico-biològiques, tractament i pronòstic. Els agents rebuts a la neoplàsia prèvia fóren: alquilants, inhibidors de la DNA topoisomerasa II, antitubulina i radioteràpia. El 95% de les LAS presentàven alteracions citogenètiques. Tretze pacients reberen quimioteràpia intensiva (amb un trasplantament de progenitors hematopoètics [TPH] en 3) i 10 només suport (supervivència mediana de 3 en front a 0,079 anys, p=0,004). El pronòstic i la resposta al tractament fóren dolents, però associaciar quimioteràpia i TPH podria perllongar la supervivència.

Call for Submissions: White Paper on Universal Health Insurance - Supporting Documents

  The Department of Health has published a White Paper on Universal Health Insurance. The White Paper sets out in detail the elements of the proposed Universal Health Insurance model for Ireland. As such, it provides detail on the overall design of the model, the proposed system for deciding on the standard package of services and the financing mechanisms for the system. This is a most fundamental reform of the health system and we recognise the importance of consulting extensively and inclusively with all interested parties.  It is important to seek your views on the policy as it is set out in the White Paper, and we view this as a valuable opportunity for citizens to contribute to the development of policy on the future of their health system.  Therefore, we would like to hear from any individual, group, organisation or other body that wishes to contribute to the consultation on the White Paper. In particular, but not limited to, we would welcome your views on the following issues: A consultation document setting out a number of key questions under each of the above headings has been developed and can be downloaded here. There is an opportunity at the end of the document for views or comments on other aspects of the White Paper to be provided. Alternatively, additional views or comments can be sent as an email or hard copy to the addresses below. It is intended to establish a separate independent Expert Commission to examine the issues around the basket of services to be provided under UHI and within the overall health system. The Minister will announce details of the Commission in the near future. Therefore, it would be useful if the submissions on the White Paper refrained from commenting in detail on the services to be provided under UHI. Views on the basket of services will be sought by the Commission when it commences its consultation process. The White Paper can be downloaded here, and two further supporting documents Background Policy Paper on Designing the Future Health Basket and Background Policy Paper on Raising Resources for Universal Health Insurance, which informed the development of the White Paper are also available for download. Links to other supporting documentation that informed the White Paper are also provided below.

Universal screening and decolonization for control of MRSA in nursing homes : a cluster randomized controlled study

OBJECTIVE The risk of carrying methicillin-resistant Staphylococcus aureus (MRSA) is higher among nursing home (NH) residents than in the general population. However, control strategies are not clearly defined in this setting. In this study, we compared the impact of standard precautions either alone (control) or combined with screening of residents and decolonization of carriers (intervention) to control MRSA in NHs. DESIGN Cluster randomized controlled trial SETTING NHs of the state of Vaud, Switzerland PARTICIPANTS Of 157 total NHs in Vaud, 104 (67%) participated in the study. INTERVENTION Standard precautions were enforced in all participating NHs, and residents underwent MRSA screening at baseline and 12 months thereafter. All carriers identified in intervention NHs, either at study entry or among newly admitted residents, underwent topical decolonization combined with environmental disinfection, except in cases of MRSA infection, MRSA bacteriuria, or deep skin ulcers. RESULTS NHs were randomly allocated to a control group (51 NHs, 2,412 residents) or an intervention group (53 NHs, 2,338 residents). Characteristics of NHs and residents were similar in both groups. The mean screening rates were 86% (range, 27%-100%) in control NHs and 87% (20%-100%) in intervention NHs. Prevalence of MRSA carriage averaged 8.9% in both control NHs (range, 0%-43%) and intervention NHs (range, 0%-38%) at baseline, and this rate significantly declined to 6.6% in control NHs and to 5.8% in intervention NHs after 12 months. However, the decline did not differ between groups (P=.66). CONCLUSION Universal screening followed by decolonization of carriers did not significantly reduce the prevalence of the MRSA carriage rate at 1 year compared with standard precautions

Stroke initial severity and outcome relative to insurance status in a universal health care system in Switzerland

Contexte et but de l'étude :Le statut socio-économique est suspecté d'avoir une influence significative sur l'incidence des attaques cérébrales (AVC), sur les facteurs de risque cardio-vasculaire, ainsi que sur le pronostic. L'influence de ce statut socio-économique sur la sévérité de l'AVC et sur les mécanismes physiopathologiques sous-jacents est moins connue.Méthode :Sur une période de 4 ans, nous avons collecté de manière prospective (dans un registre) des données concernant tous les patients avec AVC aigus admis à l'Unité Cérébrovasculaire du CHUV. Les données comprenaient le statut assécurologique du patient (assurance privée ou générale), les données démographiques, les facteurs de risque cérébrovasculaires, l'utilisation de traitements aigus de recanalisation vasculaire, le délai avant l'admission à l'hôpital, ainsi que la sévérité et le pronostic de l'AVC en phase aiguë, à 7 jours et à 3 mois des symptômes. Les patients avec assurance privée ont été comparés à ceux avec assurance générale.Résultats :Sur 1062 patients avec AVC, 203 avaient une assurance privée et 859 avaient une assurance générale. Il y a avait 585 hommes et 477 femmes. Les deux populations étaient similaires en âge. Les facteurs de risque cardio-vasculaire, la médication préventive, le délai d'arrivée à l'hôpital, l'incidence du taux de thrombolyse et l'étiologie de l'AVC ne différaient pas dans les deux populations. Le score de gravité de l'AVC en phase aiguë, mesuré par le NIHSS, était significativement plus élevé chez les patients avec assurance générale. Un pronostic favorable, mesuré par le score de Rankin modifié (mRS), était plus fréquemment obtenu à 7 jours et à 3 mois chez les patients avec assurance privée.Commentaires :Un statut socio-économique bas est associé à une incidence plus élevée de maladies cérébrovasculaires ainsi qu'à un plus mauvais pronostic, comme cela a été démontré dans différents pays. Il a été suspecté que l'accès à une prise en charge spécialisée en phase aiguë ou en rééducation soit différent selon le statut socio-économique. Comme la Suisse a un système de santé universel, avec une couverture assécurologique obligatoire pour chaque habitant, il y a là une occasion unique de comparer l'influence de l'aspect socio-économique sur la sévérité et le pronostic de l'AVC. De plus, les patients ont été admis dans la même Unité Cérébrovasculaire et pris en charge par la même équipe médicale.Conclusion et perspectives :Le lien entre le statut assécurologique et le statut socio-économique a déjà été prouvé par le passé dans d'autres pays. Nous avons mis en évidence une sévérité plus importante et un plus mauvais pronostic chez les patients avec assurance générale dans la population étudiée. L'étiologie de cette différence dans un système de santé à couverture universelle comme celui de la Suisse reste peu claire. Elle devrait être étudiée à plus grande échelle.

Prevalence of HIV type 1 drug resistance mutations in treatment-naïve and experienced patients from resource-limited settings with universal access to antiretroviral therapy: a survey in two small Brazilian cities

Concerns have been raised that universal availability of antiretroviral agents in resource-limited settings might lead to the emergence and spread of resistant strains. We present the largest survey on human immunodeficiency virus type 1 (HIV-1) resistance among treatment-naïve and experienced patients followed in small, relatively underprivileged cities in Brazil with universal availability to standard of care antiretroviral combinations. Samples were collected between 2004 and 2006 from 95 patients followed in the cities of Saquarema and Santo Antonio de Pádua, state of Rio de Janeiro. A proviral fragment encompassing protease and reverse transcriptase (RT) regions was generated and drug susceptibility level was inferred. Among 50 strains from drug-naïve subjects, one (2%) had intermediate-level resistance to RT inhibitors. Among 38 patients on therapy as of sampling, 28 (73.7%) had plasma viral load (PVL) below detection limit (26 of whom without evidence of resistance mutations) and 11 (28.9%) harbored strains with reduced susceptibility. Only two strains harbored both protease and RT inhibitor mutations. Among seven patients who were off-treatment as of sampling, two (28.5%) harbored strains with reduced susceptibility to RT inhibitors. The relatively high frequency of undetectable PVL among patients on treatment and the overall low prevalence of resistance-associated mutations are reassuring. Continued surveillance, however, is necessary.

A universal fluid cell for the imaging of biological specimens in the atomic force microscope.

Recently, atomic force microscope (AFM) manufacturers have begun producing instruments specifically designed to image biological specimens. In most instances, they are integrated with an inverted optical microscope, which permits concurrent optical and AFM imaging. An important component of the set-up is the imaging chamber, whose design determines the nature of the experiments that can be conducted. Many different imaging chamber designs are available, usually designed to optimize a single parameter, such as the dimensions of the substrate or the volume of fluid that can be used throughout the experiment. In this report, we present a universal fluid cell, which simultaneously optimizes all of the parameters that are important for the imaging of biological specimens in the AFM. This novel imaging chamber has been successfully tested using mammalian, plant, and microbial cells.

Prospective universal application of mycobacterial interspersed repetitive-unit-variable-number tandem-repeat genotyping to characterize Mycobacterium tuberculosis isolates for fast identification of clustered and orphan cases.

The use of molecular tools for genotyping Mycobacterium tuberculosis isolates in epidemiological surveys in order to identify clustered and orphan strains requires faster response times than those offered by the reference method, IS6110 restriction fragment length polymorphism (RFLP) genotyping. A method based on PCR, the mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) genotyping technique, is an option for fast fingerprinting of M. tuberculosis, although precise evaluations of correlation between MIRU-VNTR and RFLP findings in population-based studies in different contexts are required before the methods are switched. In this study, we evaluated MIRU-VNTR genotyping (with a set of 15 loci [MIRU-15]) in parallel to RFLP genotyping in a 39-month universal population-based study in a challenging setting with a high proportion of immigrants. For 81.9% (281/343) of the M. tuberculosis isolates, both RFLP and MIRU-VNTR types were obtained. The percentages of clustered cases were 39.9% (112/281) and 43.1% (121/281) for RFLP and MIRU-15 analyses, and the numbers of clusters identified were 42 and 45, respectively. For 85.4% of the cases, the RFLP and MIRU-15 results were concordant, identifying the same cases as clustered and orphan (kappa, 0.7). However, for the remaining 14.6% of the cases, discrepancies were observed: 16 of the cases clustered by RFLP analysis were identified as orphan by MIRU-15 analysis, and 25 cases identified as orphan by RFLP analysis were clustered by MIRU-15 analysis. When discrepant cases showing subtle genotypic differences were tolerated, the discrepancies fell from 14.6% to 8.6%. Epidemiological links were found for 83.8% of the cases clustered by both RFLP and MIRU-15 analyses, whereas for the cases clustered by RFLP or MIRU-VNTR analysis alone, links were identified for only 30.8% or 38.9% of the cases, respectively. The latter group of cases mainly comprised isolates that could also have been clustered, if subtle genotypic differences had been tolerated. MIRU-15 genotyping seems to be a good alternative to RFLP genotyping for real-time interventional schemes. The correlation between MIRU-15 and IS6110 RFLP findings was reasonable, although some uncertainties as to the assignation of clusters by MIRU-15 analysis were identified.

Universal features of personality traits from the observer's perspective: Data from 50 cultures

To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all. Sex differences replicated earlier self-report results, with the most pronounced differences in Western cultures. Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40. With a few exceptions, these data support the hypothesis that features of personality traits are common to all human groups.

Universal complex structures in written language

Quantitative linguistics has provided us with a number of empirical laws that characterise the evolution of languages and competition amongst them. In terms of language usage, one of the most influential results is Zipf’s law of word frequencies. Zipf’s law appears to be universal, and may not even be unique to human language. However, there is ongoing controversy over whether Zipf’s law is a good indicator of complexity. Here we present an alternative approach that puts Zipf’s law in the context of critical phenomena (the cornerstone of complexity in physics) and establishes the presence of a large-scale “attraction” between successive repetitions of words. Moreover, this phenomenon is scale-invariant and universal – the pattern is independent of word frequency and is observed in texts by different authors and written in different languages. There is evidence, however, that the shape of the scaling relation changes for words that play a key role in the text, implying the existence of different “universality classes” in the repetition of words. These behaviours exhibit striking parallels with complex catastrophic phenomena.
