The long-term association of OCD and depression and its moderators: A four-year follow up study in a large clinical sample.

BACKGROUND: Depression is the most common comorbidity in obsessive-compulsive disorder (OCD). However, the mechanisms of depressive comorbidity in OCD are poorly understood. We assessed the directionality and moderators of the OCD-depression association over time in a large, prospective clinical sample of OCD patients. METHODS: Data were drawn from 382 OCD patients participating at the Netherlands Obsessive-Compulsive Disorder Association (NOCDA) study. Cross-lagged, structural equation modeling analyses were used to assess the temporal association between OCD and depressive symptoms. Assessments were conducted at baseline, two-year and four-year follow up. Cognitive and interpersonal moderators of the prospective association between OCD and depressive symptoms were tested. RESULTS: Cross-lagged analyses demonstrated that OCD predicts depressive symptoms at two-year follow up and not vice a versa. This relationship disappeared at four-year follow up. Secure attachment style moderated the prospective association between OCD and depression. CONCLUSIONS: Depressive comorbidity in OCD might constitute a functional consequence of the incapacitating OCD symptoms. Both OCD and depression symptoms demonstrated strong stability effects between two-year and four-year follow up, which may explain the lack of association between them in that period. Among OCD patients, secure attachment represents a buffer against future depressive symptoms.

Forequarter amputation for malignancy.

BACKGROUND: Forequarter amputation (FQA) is an important treatment for malignant disease of the shoulder girdle. The aim of this study was to elucidate its role in surgical oncology. METHODS: This retrospective study analysed 40 patients who had an FQA. In nine, the chest wall was resected. The most frequent diagnoses were soft-tissue sarcoma (28 patients) and recurrent breast cancer (five). RESULTS: Median follow-up was 16 (range 1-184) months. The 1-year, 2-year and 5-year overall survival for patients with malignant disease was 71, 59 and 38 per cent respectively. The median time to local recurrence (eight patients) was 4 (range 1-19) months. Thirty-two patients had curative FQA with a 1-year, 2-year and 5-year overall survival of 90, 75 and 48 per cent respectively, and a median overall survival of 51 months. The 5-year overall and disease-free survival for soft-tissue sarcoma was 41 and 26 per cent respectively. Eight patients had a palliative FQA with a median survival of 5 (range 1-12) months. CONCLUSION: In locoregional disease such as sarcoma, FQA may offer the only possibility of cure. However, in patients with axillary metastasis, FQA has no impact on survival, although local control may improve the patient's quality of life.
