Is efficacy of transcranial magnetic stimulation targets for depression related to intrinsic functional connectivity with the subgenual cingulate?
Reported antidepressant efficacy of different left DLPFC TMS sites is related to the anticorrelation of each site with the subgenual cingulate, potentially lending insight into the antidepressant mechanism of TMS and suggesting a role for intrinsically anticorrelated networks in depression. These results can be translated into a connectivity-based targeting strategy for focal brain stimulation that might be used to optimize clinical response.
Cardiac dysfunction is a common occurrence present in patients with chronic diabetic foot ulcers, even in those without known cardiac disease or hypertension. Echocardiography may be recommended as a screening procedure in the management of diabetic patients with chronic foot ulcers. The present study supports the view that diabetic chronic foot ulcers ought to be seen as a sign of cardiac disease, although further research is needed to elucidate this issue.
