L’expérience des intervenants dans l’accompagnement vers le rétablissement des personnes vivant dans les milieux de soins de longue durée en psychiatrie

Cette étude qualitative porte sur l’expérience des intervenants dans l’accompagnement au rétablissement dans les unités d’hébergement et de soins de longue durée en psychiatrie de l’Institut universitaire en santé mentale de Québec, avec un intérêt particulier pour les difficultés et les éléments facilitant cette expérience. Neufs intervenants de différentes professions (infirmiers, professionnels, éducateurs spécialisés) ont été rencontrés entre février et juin 2014. Chacun a participé à une entrevue semi-dirigée et complété le Recovery Attitude Questionnaire, version à 7 items (RAQ-7). Les entrevues ont fait l’objet d’une analyse de contenu thématique, complétée par une analyse des pointages provenant du RAQ-7. Résultats : Trois composantes de l’expérience d’accompagnement sont inter-reliées et s’inter-influencent : l’espoir (croire), l’implication et l’attachement envers la personne aidée. Une attitude positive envers le rétablissement, la compréhension de ce concept comme processus personnel et le fait de côtoyer des collègues qui croient en la possibilité d’un rétablissement influencent positivement l’expérience. En parallèle, le fait d’être confronté à des usagers-résidents présentant des symptômes importants, une culture d’intervention orientée vers la stabilisation des symptômes et un vécu d’intervention marqué par l’échec influencent négativement l’expérience. Conclusions et implications : L’expérience d’accompagnement au rétablissement est donc influencée par différents facteurs individuels et environnementaux (voir : environnement organisationnel). La connaissance de ces facteurs peut favoriser une implantation réussie de modes d’intervention favorables au rétablissement des usagers dans les milieux d’hébergement et de soins de longue durée en psychiatrie. Mots clés : rétablissement, maladie mentale sévère, Centre d’hébergement et de soins de longue durée, vécu des intervenants, intervenants, interventions, pratiques orientées vers le rétablissement.

Pollen Allergy in Cordoba City: Frequency of Sensitization and Relation with Antihistamine Sales

The occurrence of symptoms in pollen allergy patients in urban areas may be affected by local environmental factors such as sources of pollution, natural and ornamental vegetation, local architecture impeding dispersion, etc. The aim of this study was to analyse the frequency of sensitization in pollen allergy patients and the relationship with antihistamine sales. For this study, a large number of clinical records, together with pharmaceutical and pollen data, were collected between 1999 and 2001 in the city of Córdoba, in the south of the Iberian Peninsula. Differences were observed in the symptoms suffered by pollen allergy patients in different areas of the city due to varying local emission of both biological and non-biological particles. Temporal distribution of symptoms over the three study years was influenced by meteorological factors, especially rainfall patterns; higher water supply to plants was associated with increased airborne pollen concentrations. Air pollution might be one of the main factors affecting the distribution of pollen allergy patients within the city. Recent years have seen a worsening of symptoms and increased sensitization to urban species such as plane-trees.

Application of Redundancy Analysis for Aerobiological Data

An aerobiological survey was conducted through five consecutive years (2006–2010) at Worcester (England).The concentration of 20 allergenic fungal spore types was measured using a 7-day volumetric spore trap. The relationship between investigated fungal spore genera and selected meteorological parameters (maximum, minimum, mean and dew point temperatures, rainfall, relative humidity, air pressure,wind direction) was examined using an ordination method(redundancy analysis) to determine which environmental factors favoured their most abundance in the air and whether it would be possible to detect similarities between different genera in their distribution pattern. Redundancy analysis provided additional information about the biology of the studied fungi through the results of the Spearman’s rank correlation. Application of the variance inflation factor in canonical correspondence analysis indicated which explanatory variables were auto-correlated and needed to be excluded from further analyses. Obtained information will be consequently implemented in the selection of factors that will be a foundation for forecasting models for allergenic fungal spores in the future.

Prediction of breast cancer risk based on profiling with common genetic variants

BACKGROUND: Data for multiple common susceptibility alleles for breast cancer may be combined to identify women at different levels of breast cancer risk. Such stratification could guide preventive and screening strategies. However, empirical evidence for genetic risk stratification is lacking. METHODS: We investigated the value of using 77 breast cancer-associated single nucleotide polymorphisms (SNPs) for risk stratification, in a study of 33 673 breast cancer cases and 33 381 control women of European origin. We tested all possible pair-wise multiplicative interactions and constructed a 77-SNP polygenic risk score (PRS) for breast cancer overall and by estrogen receptor (ER) status. Absolute risks of breast cancer by PRS were derived from relative risk estimates and UK incidence and mortality rates. RESULTS: There was no strong evidence for departure from a multiplicative model for any SNP pair. Women in the highest 1% of the PRS had a three-fold increased risk of developing breast cancer compared with women in the middle quintile (odds ratio [OR] = 3.36, 95% confidence interval [CI] = 2.95 to 3.83). The ORs for ER-positive and ER-negative disease were 3.73 (95% CI = 3.24 to 4.30) and 2.80 (95% CI = 2.26 to 3.46), respectively. Lifetime risk of breast cancer for women in the lowest and highest quintiles of the PRS were 5.2% and 16.6% for a woman without family history, and 8.6% and 24.4% for a woman with a first-degree family history of breast cancer. CONCLUSIONS: The PRS stratifies breast cancer risk in women both with and without a family history of breast cancer. The observed level of risk discrimination could inform targeted screening and prevention strategies. Further discrimination may be achievable through combining the PRS with lifestyle/environmental factors, although these were not considered in this report.

Values in middle childhood: Social and genetic contributions

Theories of value development often identify adolescence as the period for value formation, and cultural and familial factors as the sources for value priorities. However, recent research suggests that value priorities can be observed as early as in middle childhood, and several studies, including one on preadolescents (Knafo & Spinath, 2011), have suggested a genetic contribution to individual differences in values. In the current study, 174 pairs of monozygotic and dizygotic 7-year old Israeli twins completed the Picture-Based Value Survey for Children (PBVS–C; Döring et al., 2010). We replicated basic patterns of relations between value priorities and variables of socialisation – gender, religiosity, and socioeconomic status– that have been found in studies with adults. Most important, values of Self-transcendence, Self-enhancement, and Conservation, were found to be significantly affected by genetic factors (29%, 47% and 31% respectively), as well as non-shared environment (71%, 53% and 69% respectively). Openness to change values, in contrast, were found to be unaffected by genetic factors at this age and were influenced by shared (19%) and non-shared (81%) environment. These findings support the recent view that values are formed at earlier ages than had been assumed previously, and they further our understanding of the genetic and environmental factors involved in value formation at young ages.
