Marcia J. Bates: El context i la interacció han de ser elements bàsics en els sistemes de recuperació de la informació

Entrevista a Marcia J. Bates a la University od California at Los Angeles i experta en sistemes de recuperació de la Informació orientats a l'usuari i en representació del contingut i accés per matèries. Es parla de l'evolució de les tecnologies i l'automatització de tasques que requereixen la capacitat de raonament de la persona, del comportament de l'usuari quan cerca per matèries, de la formació en competències en el maneig de la informació, de la necessitat del context en la indexació i la recuperació per matèries, i l'empatia en les relacions entre bibliotecaris i usuaris.

Narrativa de mujeres en Costa Rica: personajes femeninos en los Cuentos de mi tía Panchita

Este trabajo tiene como objetivo el adentrarse en algunos de los cuentos infantiles de una reconocida autora de Costa Rica, los Cuentos de mi tía Panchita de Carmen Lyra, y descubrir, mediante un análisis de ciertos de sus personajes femeninos desde un marco relacionado con teoría literaria feminista, elementos del discurso que permitan entrever o evidenciar la presencia de roles tradicionales de las mujeres o transgresiones a esos patrones, con mayor atención a la Costa Rica de principios del siglo XX

Impacto de la utilización de hígados de donantes anti-HBc positivo en pacientes trasplantados por hepatitis B

El nostre objectiu és avaluar l’impacte de la utilització de fetges de donants anti-HBc positius en pacients trasplantats per hepatitis B, els quals van ser revisats de manera retrospectiva. La probabilitat acumulada d’hepatitis B post-trasplantament al 1er, 5é i 10é any va ésser del 3,7%, 8,3% i 8,3% en els receptors d’un empelt anti-HBc+ en comparació amb el 2,7%, 9,8% i 9,8% en els que varen rebre un empelt anti-HBc- (p=0,99). La probabilitat de supervivència al 1er, 5é i 10é any dels receptors d’un òrgan anti-HBc+ va ésser del 87%, 82% i 58% front al 87%, 82% i 74% en els que varen rebre un anti-HBc- (p=0,73). La utilització de donants anti-HBc positius no afecta ni a la supervivència ni al desenvolupament de hepatitis B en pacients trasplantats per VHB.

Family burden related to clinical and functional variables of people with intellectual disability with and without a mental disorder

Few studies have been found that to assess the factors that explain higher levels of familyburden in adults with intellectualdisability (ID) and intellectualdisability and mental disorders (ID-MD). The aims of this study were to assess familyburden in people with ID and ID-MD and to determine which sociodemographic, clinical and functionaldisabilityvariables account for familyburden. The sample is composed of pairs of 203 participants with disability and their caregivers, of which 33.5% are caregivers of people with ID and 66.5% of ID-MD. Assessments were performed using scales of clinical and functionaldisability as the following instruments: Weschler Adult Intelligence Scale-III (WAIS-III), Inventory for Client and Agency Planning (ICAP), Psychiatric Assessment Schedule for Adults with Development Disability (PAS-ADD checklist), Disability Assessment Schedule of the World Health Organization (WHO-DAS-II) and familyburden (Subjective and Objective FamilyBurden Inventory - SOFBI/ECFOS-II). People with ID-MD presented higher levels of functionaldisability than those with ID only. Higher levels of familyburden were related to higher functionaldisability in all the areas (p < 0.006-0.001), lower intelligence quotient (p < 0.001), diagnosis of ID-MD (p < 0.001) and presence of organic, affective, psychotic and behavioral disorders (p < 0.001). Stepwise multiple regression showed that behavioral problems, affective and psychotic disorder, disability in participation in society, disability in personal care and presence of ID-MD explained more than 61% of the variance in familyburden. An integrated approach using effective multidimensional interventions is essential for both people with ID and ID-MD and their caregivers in order to reduce familyburden.

Family impact in intellectual disability, severe mental health disorders and mental health disorders in ID. A comparison

Family impact (or family burden) is a concept born in the field of mental health that has successfully been exported to the ambit of intellectual disability (ID). However, differences in family impact associated with severe mental health disorders (schizophrenia), to ID or to mental health problems in ID should be expected. Seventy-two adults with intellectual disability clients of the Carmen Pardo-Valcarce Foundation's sheltered workshops and vocational employment programmes in Madrid (Spain), 203 adults diagnosed with schizophrenia from four Spanish Community Mental Health Services (Barcelona, Madrid, Granada and Navarra) and 90 adults with mental health problems in ID (MH-ID) from the Parc Sanitari Sant Joan de Déu Health Care Site in Sant Boi de Llobregat, Barcelona (Spain) were asked to participate in the present study along with their main caregivers. Family impact experienced by caregivers was assessed with the ECFOS-II/SOFBI-II scale (Entrevista de Carga Familiar Objetiva y Subjetiva/Objective and Subjective Family Burden Interview). In global terms, results showed that the higher family impact was found between caregivers to people with MH-ID. The interaction of both conditions (ID and mental health problems) results in a higher degree of burden on families than when both conditions are presented separately. There was also an impact in caregivers to people with schizophrenia, this impact being higher than the one detected in caregivers to people with intellectual disability. Needs of caregivers to people with disability should be addressed specifically in order to effectively support families.

Ancient dispersal of the human fungal pathogen Cryptococcus gattii from the Amazon rainforest

Over the past two decades, several fungal outbreaks have occurred, including the high-profile 'Vancouver Island' and 'Pacific Northwest' outbreaks, caused by Cryptococcus gattii, which has affected hundreds of otherwise healthy humans and animals. Over the same time period, C. gattii was the cause of several additional case clusters at localities outside of the tropical and subtropical climate zones where the species normally occurs. In every case, the causative agent belongs to a previously rare genotype of C. gattii called AFLP6/VGII, but the origin of the outbreak clades remains enigmatic. Here we used phylogenetic and recombination analyses, based on AFLP and multiple MLST datasets, and coalescence gene genealogy to demonstrate that these outbreaks have arisen from a highly-recombining C. gattii population in the native rainforest of Northern Brazil. Thus the modern virulent C. gattii AFLP6/VGII outbreak lineages derived from mating events in South America and then dispersed to temperate regions where they cause serious infections in humans and animals.
