[The care standard 'Depressive disorders']. / De zorgstandaard Depressieve stoornissen.

BACKGROUND: The care standard 'Depressive disorders' describes the complete patient journey for patients with depressive symptoms and disorders from the age of 8 years onwards.
AIM: To describe the most important recommendations in this care standard.
METHOD: The care standard is an adaptation of the existing guidelines for depression, supplemented with practical knowledge from professionals and patients' values and preferences.
RESULTS: Core elements in the care for depression are an appropriate use of care and a focus on relapse prevention. A combination of psychotherapy and medication is indicated for persistent depression and more sessions of psychotherapy might be required. There is some evidence for the use of repetitive transcranial magnetic stimulation in treatment-resistant depression.
CONCLUSION: The care standard is an important instrument to improve the quality of care for depression at both the organisational and the regional level.

The utility of a long-term acoustic recording system for detecting white seabass Atractoscion nobilis spawning sounds.

This study reports the use of a long-term acoustic recording system (LARS) to remotely monitor white seabass Atractoscion nobilis spawning sounds at three sites along the southern California coastline, adjacent to Camp Pendleton. On the basis of previous studies of A. nobilis sound production relative to periods of known spawning activity, LARS were set to continuously record ambient sounds for a 2 h period around sunset from April to June 2009. Acoustic analyses identified A. nobilis courtship sounds on 89, 28 and 45% of the days at the three locations, respectively. From 474 h of acoustic data, spawning-related sounds (chants) were detected on 19 occasions in 2009 with an additional 11 spawning chants recorded during a 2007 validation period. Most spawning chants occurred within 30 min of sunset during the months of May and June at a mean ±S.D. surface temperature of 18.2 ± 1.2° C. Consecutive daily spawning activity was not apparent at any sites in 2009. Atractoscion nobilis spawning chants were recorded at all three sites, suggesting that shallow rocky reefs which support kelp forests provide suitable A. nobilis spawning habitat. Results confirm the utility of passive acoustic recorders for identifying A. nobilis spawning periods and locations.

The functional role of the caudal fin in the feeding ecology of the common thresher shark Alopias vulpinus.

This study tests the hypothesis that the common thresher shark Alopias vulpinus uses its elongate caudal fin to both produce thrust and immobilize prey during feeding. Underwater video recorded in southern California from 2007 to 2009 revealed 34 feeding events, all of which were initiated with the upper lobe of the caudal fin.
