Objective: The aim of this paper is to determine potentially modifiable factors associated with the high proportion of patients who are readmitted to adolescent psychiatric units.
Method: The case notes of 112 adolescents admitted over 1 year to an acute adolescent psychiatry unit were reviewed. Socio-demographic and clinical variables were compared between those who were readmitted over a 12-month period post discharge and those who were not.
Results: The readmission rate over a 12-month period was 31%. Males were significantly more likely to be readmitted. No other statistically significant predictors of readmission were identified. There was a trend towards readmission for those with bipolar disorder and a trend away from readmission for those with adjustment disorders. A history of sexual abuse and cluster B personality traits were significantly related to a history of previous admission, but not with subsequent readmission.
Conclusions: Readmission is influenced by a number of factors, which may not be easily identified by a chart review. Prospective studies which follow-up adolescents for several years after discharge are needed.
All-reflective interferometric gravitational-wave detector configurations with a diffraction grating as a power beam splitter have been proposed to reduce thermal lensing. We demonstrate the use of a diffraction grating as a polarization beam splitter in a zero-area polarization Sagnac interferometer.
Figure 1: Closeup of Neill Blomkamp's Elysium. c 2013 CTMG.During Neill Blomkamp's sci-fi epic Elysium (Fig.1), we experienced severe noise issues when ray-tracing the glossy reflections and heavy indirect lighting on the colossal habitat, within a tight production schedule. We present a new solution to the common issue of ray-traced noise, drastically reducing render times by expanding the use of a temporal filter to attenuate the weighting of a non-local means algorithm which selectively refines it's result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
