El consum d’alcohol juntament amb els altres problemes relacionats amb el consum de tòxics ha estat en molt casos un element que ha tingut un paper significatiu en la comissió del delicte tant com a factor causal com facilitador. El consum d’alcohol i els problemes associats queden ocults quan el subjecte ingressa a presó arran de la no-disponibilitat de la substància i és en reiniciar els contactes amb el medi exterior que sovint aquest problema torna a aparèixer progressivament si no ha estat abordat prèviament. Aquest protocol elaborat per una comunitat de psicòlegs de centres penitenciaris de Catalunya pretén trobar una metodologia comuna d’avaluació i intervenció davant els consums actuals d’alcohol i la detecció dels subjectes amb història personal de risc de consum perjudicial.

BACKGROUND AND PURPOSE: We compared among young patients with ischemic stroke the distribution of vascular risk factors among sex, age groups, and 3 distinct geographic regions in Europe. METHODS: We included patients with first-ever ischemic stroke aged 15 to 49 years from existing hospital- or population-based prospective or consecutive young stroke registries involving 15 cities in 12 countries. Geographic regions were defined as northern (Finland, Norway), central (Austria, Belgium, France, Germany, Hungary, The Netherlands, Switzerland), and southern (Greece, Italy, Turkey) Europe. Hierarchical regression models were used for comparisons. RESULTS: In the study cohort (n=3944), the 3 most frequent risk factors were current smoking (48.7%), dyslipidemia (45.8%), and hypertension (35.9%). Compared with central (n=1868; median age, 43 years) and northern (n=1330; median age, 44 years) European patients, southern Europeans (n=746; median age, 41 years) were younger. No sex difference emerged between the regions, male:female ratio being 0.7 in those aged <34 years and reaching 1.7 in those aged 45 to 49 years. After accounting for confounders, no risk-factor differences emerged at the region level. Compared with females, males were older and they more frequently had dyslipidemia or coronary heart disease, or were smokers, irrespective of region. In both sexes, prevalence of family history of stroke, dyslipidemia, smoking, hypertension, diabetes mellitus, coronary heart disease, peripheral arterial disease, and atrial fibrillation positively correlated with age across all regions. CONCLUSIONS: Primary preventive strategies for ischemic stroke in young adults-having high rate of modifiable risk factors-should be targeted according to sex and age at continental level.
Modern Vaccines/Adjuvants Formulation-Session 2 (Plenary II): May 15-17, 2013-Lausanne, Switzerland.
Resumo:
On the 15-17th May 2013, the Fourth International Conference on Modern Vaccines/Adjuvants Formulation was organized in Lausanne, Switzerland, and gathered stakeholders from academics and from the industry to discuss several challenges, advances and promises in the field of vaccine adjuvants. Plenary session 2 of the meeting was composed of four different presentations covering: (1) the recent set-up of an adjuvant technology transfer and training platform in Switzerland, (2) the proposition to revisit existing paradigms of modern vaccinology, (3) the properties of polyethyleneimine as potential new vaccine adjuvant, and (4) the progresses in the design of HIV vaccine candidates able to induce broadly neutralizing antibodies.

Supported by IEEE 802.15.4 standardization activities, embedded networks have been gaining popularity in recent years. The focus of this paper is to quantify the behavior of key networking metrics of IEEE 802.15.4 beacon-enabled nodes under typical operating conditions, with the inclusion of packet retransmissions. We corrected and extended previous analyses by scrutinizing the assumptions on which the prevalent Markovian modeling is generally based. By means of a comparative study, we singled out which of the assumptions impact each of the performance metrics (throughput, delay, power consumption, collision probability, and packet-discard probability). In particular, we showed that - unlike what is usually assumed - the probability that a node senses the channel busy is not constant for all the stages of the backoff procedure and that these differences have a noticeable impact on backoff delay, packet-discard probability, and power consumption. Similarly, we showed that - again contrary to common assumption - the probability of obtaining transmission access to the channel depends on the number of nodes that is simultaneously sensing it. We evidenced that ignoring this dependence has a significant impact on the calculated values of throughput and collision probability. Circumventing these and other assumptions, we rigorously characterize, through a semianalytical approach, the key metrics in a beacon-enabled IEEE 802.15.4 system with retransmissions.
