Italian guidelines for primary headaches: 2012 revised version

The first edition of the Italian diagnostic and therapeutic guidelines for primary headaches in adults was published in J Headache Pain 2(Suppl. 1):105–190 (2001). Ten years later, the guideline committee of the Italian Society for the Study of Headaches (SISC) decided it was time to update therapeutic guidelines. A literature search was carried out on Medline database, and all articles on primary headache treatments in English, German, French and Italian published from February 2001 to December 2011 were taken into account. Only randomized controlled trials (RCT) and meta-analyses were analysed for each drug. If RCT were lacking, open studies and case series were also examined. According to the previous edition, four levels of recommendation were defined on the basis of levels of evidence, scientific strength of evidence and clinical effectiveness. Recommendations for symptomatic and prophylactic treatment of migraine and cluster headache were therefore revised with respect to previous 2001 guidelines and a section was dedicated to non-pharmacological treatment. This article reports a summary of the revised version published in extenso in an Italian version

Lexical organization in bilinguals and L2 learners - A study of lexical access and cognate representation

The current study investigates how bilinguals and second language learners’ mental lexicons are organized. Studying how learners access their mental lexicon provides information on how cognates (words with similar or identical form) are represented in the mental lexicon, and further whether the mental lexicons are overlapped or unconnected. Through a lexical decision experiment, reaction times to cognates and noncognates of corresponding frequencies were compared. We tested whether accessing a word in one lexicon activated its counterpart in the other (nonselective access), or only activated the representation in the used language (selective access). Nonselective access suggests that cognates have one shared representation across languages, and selective access proposes that cognates have two separate representations (one for each language). The results showed no differences in reaction times, suggesting evidence for lexical access being selective, that cognates have two representations in the mind, and that the mental lexicons are unconnected. There were no differences in reaction times between the bilingual and L2 learner group, indicating that proficient L2 learners and bilinguals access their mental lexicons comparably, suggesting similar lexical organization

Nursing interventions focusing at delirium : A literature study

Introduktion:Delirium är ett begrepp som betyder ”ur spåret” som beskriver människor i tillstånd av agitation eller överdriven trötthet. Detta tillståndet har multifaktoriella orsaker, exempelvis hög ålder, infektion etc. Mest effektiva sättet att hantera delirium är att förhindra dess uppkomst samt att ta hjälp av diagnostiska instrument. Syfte:Syftet med studien var attbeskriva omvårdnadsinterventioner vid deliriumtillstånd. Metod:Litteraturstudien utfördes enligt Polit och Becks nio steg. Resultatet utgick ifrån 14 artiklar. Av dessa var 2 kvalitativa, 10 kvantitativa samt 2 mixad metod. Databaserna som artiklarna hämtades ifrån var CINAHL och PubMed. Resultat: I studien framkom det sex kategorier: screening för delirium, samverkan med närstående, miljöanpassning, fysisk begränsning,sömn och vila samt farmakologiska interventioner.Slutsats:Resultaten visade att övervägande del av sjuksköterskor mött problem med att identifiera delirium, dess orsaker samt tillämpa relevanta omvårdnadsåtgärder. Rutiner för att bedöma patientens kognitiva tillstånd för att identifiera underliggande problem och förbättring av dessa skulle kunna bidra till snabbare återhämtning
