OBJECTIVE
To determine whether depression is associated with worse cardiac disease severity in patients with stable coronary heart disease (CHD). There is considerable evidence that depression is a risk factor for adverse cardiovascular events in patients with CHD. However, a frequent criticism of this literature is that the association between depression and adverse cardiovascular outcomes may be confounded by worse baseline cardiac disease severity in depressed patients.
METHOD
In a sample of 1020 outpatients with stable CHD, we examined the association between major depression (assessed using the Computerized National Institute of Mental Health Diagnostic Interview Schedule) with measures of cardiac disease severity, including systolic dysfunction, diastolic dysfunction, exercise-induced ischemia, and cardiac wall motion abnormalities. Cross-sectional univariate and multivariate models controlling for demographic and clinical variables were computed.
RESULTS
Of the 1020 participants, 224 (22%) had current (past month) major depression. After adjustment for age, major depression was not associated with systolic dysfunction, diastolic dysfunction, inducible ischemia, or cardiac wall motion abnormalities. Similarly, multivariate models revealed no significant relationship between major depression and cardiac disease severity.
CONCLUSIONS
Overall, we found little evidence that depression is associated with worse cardiac disease severity. This suggests that greater baseline cardiac disease severity is unlikely to be responsible for the increased risk of CHD events in depressed patients.

PURPOSE
Colonic lipomas are benign, submucosal tumours that are usually asymptomatic. Typically, they are incidentally diagnosed during colonoscopy. Due to a low prevalence, the natural history of lipomas remains largely unknown. While large (>2 cm) lesions can cause symptoms and complications, their endoscopic treatment is not routinely recommended because of prior reports of a high rate of perforation.
METHODS
We used a standardized technique of polypectomy, using endoscopic looping to resect large colonic lipomas in 8 patients and followed their clinical outcomes.
RESULTS
The mean lipoma size was 3.8+/-1.2 cm (range 2.5-6 cm). No patient developed bleeding or perforation. On follow-up (mean=13.5 months, range 2-29), there was one small residual lesion.
CONCLUSION
Colonic lipomas larger than 2 cm can be safely and efficaciously removed using endoloop assisted polypectomy technique.
