Clinical characterization of 66 patients with congenital retinal disease due to the deep-intronic c.2991+1655A>G mutation in CEP290
Purpose: To describe the phenotypic spectrum of retinal disease caused by the c.2991+1655A>G mutation in CEP290 and to compare disease severity between homozygous and compound heterozygous patients.
Methods: Medical records were reviewed for best-corrected visual acuity (BCVA), age of onset, fundoscopy descriptions. Foveal outer nuclear layer (ONL) and ellipsoid zone (EZ) presence was assessed using spectral-domain optical coherence tomography (SD-OCT). Differences between compound heterozygous and homozygous patients were analyzed based on visual performance and visual development.
Results: A total of 66 patients were included. The majority of patients had either light perception or no light perception. In the remaining group of 14 patients, median BCVA was 20/195 Snellen (0.99 LogMAR; range 0.12-1.90) for the right eye, and 20/148 Snellen (0.87 LogMAR; range 0.22-1.90) for the left. Homozygous patients tended to be more likely to develop light perception compared to more severely affected compound heterozygous patients (P = 0.080) and are more likely to improve from no light perception to light perception (P = 0.022) before the age of 6 years. OCT data were available in 12 patients, 11 of whom had retained foveal ONL and EZ integrity up to 48 years (median 23 years) of age.
Conclusions: Homozygous patients seem less severely affected compared to their compound-heterozygous peers. Improvement of visual function may occur in the early years of life, suggesting a time window for therapeutic intervention up to the approximate age of 17 years. This period may be extended by an intact foveal ONL and EZ on OCT
The effect of five years versus two years of specialised assertive intervention for first episode psychosis - OPUS II: study protocol for a randomized controlled trial
<p>Abstract</p> <p>Background</p> <p>The Danish OPUS I trial randomized 547 patients with first-episode psychosis to a two-year early-specialised assertive treatment programme (OPUS) versus standard treatment. The two years OPUS treatment had significant positive effects on psychotic and negative symptoms, secondary substance abuse, treatment adherence, lower dosage of antipsychotic medication, and a higher treatment satisfaction. However, three years after end of the OPUS treatment, the positive clinical effects were not sustained, except that OPUS-treated patients were significantly less likely to be institutionalised compared with standard-treated patients. The major objective of the OPUS II trial is to evaluate the effects of five years of OPUS treatment versus two years of OPUS treatment.</p> <p>Methods</p> <p>The OPUS II trial is designed as a randomized, open label, parallel group trial with blinded outcome assessment. Based on our sample size estimation, 400 patients treated in OPUS for two years will be randomized to further three years of OPUS treatment versus standard treatment. The specialized assertive OPUS treatment consists of three core elements: assertive community treatment, psycho-educational family treatment, and social skills training.</p> <p>Discussion</p> <p>It has been hypothesized that there is a critical period from onset up to five years, which represents a window of opportunity where a long-term course can be influenced. Extending the specialized assertive OPUS treatment up to five years may allow the beneficial effects to continue beyond the high-risk period, through consolidation of improved social and functional outcome.</p> <p>Trial registration</p> <p>Clinical Trial.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT00914238">NCT00914238</a></p

Change in cannabis use, clinical symptoms and social functioning among patients with first-episode psychosis:a 5-year follow-up study of patients in the OPUS trial
High Throughput Identification and Quantification of Phospholipids in Complex Mixtures
We
present a fully automatic method, <i>autoP</i>, for
identification and quantification of lipids in complex lipid mixtures
from 1D <sup>31</sup>P and 2D <sup>1</sup>H–<sup>31</sup>P
NMR spectra. The <sup>31</sup>P chemical shifts in lipids are highly
sensitive to experimental conditions such as pH and temperature, so
the present method uses the much more unambiguous <sup>1</sup>H chemical
shifts for assignment and <sup>31</sup>P intensities for quantification.
By using 2D <sup>1</sup>H–<sup>31</sup>P total correlation
spectroscopy (TOCSY) correlation experiments, we demonstrate that
approximately 20 different lipids can be automatically and unambiguously
assigned and quantified by this automatic method

Development of selective gears and technologies for commercial fisheries (SELEKT)
The SELEKT project set out to develop and test new selective fishing gears and technologies, as well as document their selective effect with a view to these being implemented in commercial fishing in the North Sea, Skagerrak, Kattegat and the Baltic Sea. The project was divided into two main pillars, the first being the adaptive development of selective fishing gears in direct co-operation with the industry (section 2 - 4) and the second focusing on building up knowledge on novel methodologies and preparing their application in fisheries (section 5). The gears developed under the 1st pillar were done so following the cooperative model between industry (fishers and net makers) and researchers, which was developed and tested in the Fast-Track projects. The technologies developed in pillar 2 focused on the collection of data, in real time, while fishing, the collection of data onboard fishing vessels, the use of new technologies to ob- serve fish behavior inside the trawl, and the use of technologies to reduce the impact trawling has on the seabed.During the project, issues in a number of different fisheries throughout Danish waters were highlighted. All gears developed pertained to the demersal trawl fisheries, namely the Baltic Sea trawl fishery targeting flatfish, the Pandalus trawl fishery, the mixed demersal trawl fishery, the Norway lobster trawl fishery, and the Brown shrimp beam trawl fishery. The gears tested either aimed at reducing catches of unwanted species and/or sizes. In total, 20 gears were developed during the life of the project, 12 of which have been tested onboard commercial (10) and research vessels (2), and 8 of which were developed and tested in the flume tank towards the end of the project and are still to be tested.This report provides and overview of the work undertaken during the project and presents the results from the individual trials in the form of fact sheets (Appendix 1). Furthermore, the report highlights some of the challenges which arose during the project and how these can be addressed in the future
National clinical Genetic Networks - GENets - Establishment of expert collaborations in Denmark
Genetic conditions are often familial, but not all relatives receive counseling from the same institution. It is therefore necessary to ensure consistency in variant interpretation, counseling practices, and clinical follow up across health care providers. Furthermore, as new possibilities for gene-specific treatments emerge and whole genome sequencing becomes more widely available, efficient data handling and knowledge sharing between clinical laboratory geneticists and medical specialists in clinical genetics are increasingly important. In Denmark, these needs have been addressed through the establishment of collaborative national networks called Genetic Expert Networks or "GENets". These networks have enhanced patient and family care significantly by bringing together groups of experts in national collaborations. This promotes coordinated clinical care, the dissemination of best clinical practices, and facilitates the exchange of new knowledge.</p
