Mortality after discharge from long-term psychiatric care in Scotland, 1977 – 94: a retrospective cohort study
BACKGROUND: Recent United Kingdom strategies focus on preventable suicide deaths in former psychiatric in-patients, but natural causes of death, accidents and homicide may also be important. This study was intended to find the relative importance of natural and unnatural causes of death in people discharged from long-term psychiatric care in Scotland in 1977 –1994. METHODS: People discharged alive from psychiatric hospitals in Scotland in 1977 – 94 after a stay of one year or longer were identified using routine hospital records. Computer record linkage was used to link hospital discharges to subsequent death records. Mortality was described using a person-years analysis, and compared to the general population rates. RESULTS: 6,776 people were discharged in the time period. 1,994 people (29%) died by the end of follow-up, 732 more deaths than expected. Deaths from suicide, homicide, accident and undetermined cause were increased, but accounted for only 197 of the excess deaths. Deaths from respiratory disease were four times higher than expected, and deaths from other causes, including cardiovascular disease, were also elevated. CONCLUSION: Suicide is an important cause of preventable mortality, but natural causes account for more excess deaths. Prevention activities should not focus only on unnatural causes of death
Mineralogy and Elemental Composition of Wind Drift Soil at Rocknest, Gale Crater
The Mars Science Laboratory rover Curiosity has been exploring Mars since August 5, 2012, conducting engineering and first-time activities with its mobility system, arm, sample acquisition and processing system (SA/SPaH-CHIMRA) and science instruments. Curiosity spent 54 sols at a location named "Rocknest," collecting and processing five scoops of loose, unconsolidated materials ("soil") acquired from an aeolian bedform (Fig. 1). The Chemistry and Mineralogy (CheMin) instrument analyzed portions of scoops 3, 4, and 5, to obtain the first quantitative mineralogical analysis of Mars soil, and to provide context for Sample Analysis at Mars (SAM) measurements of volatiles, isotopes and possible organic materials
Quality of Longer Term Mental Health Facilities in Europe: Validation of the Quality Indicator for Rehabilitative Care against Service Users’ Views
BACKGROUND: The Quality Indicator for Rehabilitative Care (QuIRC) is a staff rated, international toolkit that assesses care in longer term hospital and community based mental health facilities. The QuIRC was developed from review of the international literature, an international Delphi exercise with over 400 service users, practitioners, carers and advocates from ten European countries at different stages of deinstitutionalisation, and review of the care standards in these countries. It can be completed in under an hour by the facility manager and has robust content validity, acceptability and inter-rater reliability. In this study, we investigated the internal validity of the QuIRC. Our aim was to identify the QuIRC domains of care that independently predicted better service user experiences of care. METHOD: At least 20 units providing longer term care for adults with severe mental illness were recruited in each of ten European countries. Service users completed standardised measures of their experiences of care, quality of life, autonomy and the unit's therapeutic milieu. Unit managers completed the QuIRC. Multilevel modelling allowed analysis of associations between service user ratings as dependent variables with unit QuIRC domain ratings as independent variables. RESULTS: 1750/2495 (70%) users and the managers of 213 units from across ten European countries participated. QuIRC ratings were positively associated with service users' autonomy and experiences of care. Associations between QuIRC ratings and service users' ratings of their quality of life and the unit's therapeutic milieu were explained by service user characteristics (age, diagnosis and functioning). A hypothetical 10% increase in QuIRC rating resulted in a clinically meaningful improvement in autonomy. CONCLUSIONS: Ratings of the quality of longer term mental health facilities made by service managers were positively associated with service users' autonomy and experiences of care. Interventions that improve quality of care in these settings may promote service users' autonomy
COLOUR CENTRES IN ALKALI HALIDES (2).Defects induced in NaMgF3 crystals by X- and VUV-irradiation
Les effets d'irradiations X et UV sous vide de monocristaux de NaMgF3 ont été étudiés par des méthodes optiques et électriques. L'analyse spectrale de la luminescence X(XL) a mis en évidence des bandes d'émission à 275, 325, 390, 505 et 575 nm. Après une irradiation X prolongée à 80 K, des bandes d'absorption à 245, 290 et 345 nm sont apparues, et on les a attribuées respectivement à des interstitiels, des centres F et des centres VK. Le blanchiment thermique de ces bandes s'accompagne de pics de TSL et de TSC. On a trouvé également une corrélation entre la composition spectrale et sa variation avec la température pour la luminescence X et pour la TSL. De même, après irradiation monochromatique par UV sous vide, quelques-uns des pics de TSL ont pu être observés. Le spectre d'excitation de cette TSL présente des pics à 142 et 146 nm. Ces résultats indiquent que c'est un processus de radiolyse qui est responsable de la formation des défauts lors des irradiations des échantillons aussi bien par X que par UV sous vide.Effects of X and monochromatic VUV irradiation on single NaMgF3 crystals, were investigated by optical and electrical methods. Spectral decomposition of the X-luminescence (XL) showed main emission bands at 275, 325, 390, 505 and 575 nm. Prolonged X-irradiation at 80 K caused the appearance of absorption bands at 245, 290 and 345 nm which are attributed to interstitials, F and VK centers respectively. Thermal annealing of these bands were accompanied by the appearance of TSL and TSC glow peaks. A correlation was also found between the spectral composition and temperature dependence of the XL and the TSL emission. Some of the glow peaks appear also after monochromatic VUV irradiation. TSL excitation spectra showed maxima at 142 and 146 nm. Results indicate that a radiolysis process is responsible for defect formation in both the X and VUV irradiated samples
