Highfield imaging of the subgenual anterior cingulate cortex in uni- and bipolar depression.

Background: The subgenual Anterior Cingulate Cortex (sgACC), as a part of the Anterior Cingulate Cortex and the limbic system plays a crucial role in mood regulation. Previous structural and functional brain imaging studies of the sgACC have revealed alterations of Gray Matter (GM) volumes and Blood Oxygenation Level Dependent signals (BOLD) in patients with Major Depressive Disorder (MDD) and Bipolar Disorder (BD), suggesting potential biomarker traits for affective disorders.

Method: In this study we investigated the gray matter volume of the sgACC in 3 different patient groups: 40 MDD patients, of which 20 were medicated (MDDm) and 20 were unmedicated (MDDu), and 21 medicated BD patients, and compared them with 23 healthy volunteers.

E-mental health in Germany - what is the current use and what are experiences of different types of health care providers for patients with mental illnesses?

Background: As a new and effective support option, e-mental health interventions can be useful in complementing treatment in mental health care. To date, little is known about how health care providers use these programs to treat patients with mental illnesses in Germany. The present study aims to examine the use of and experiences with e-mental health interventions from the point of view of different types of health care providers for patients with mental illnesses.

Mammillary body and hypothalamic volumes in mood disorders.

We have previously reported an in vivo enlargement of the left hypothalamus in mood disorders using 7 T magnetic resonance imaging. The aim of this follow-up study was to find out whether the hypothalamic volume difference may be located in the mammillary bodies (MB) rather than being widespread across the hypothalamus. We developed and evaluated a detailed segmentation algorithm that allowed a reliable segmentation of the MBs, and applied it to 20 unmedicated (MDDu) and 20 medicated patients with major depressive disorder, 21 medicated patients with bipolar disorder, and 23 controls.

Afferent vagal stimulation via gastric electrical stimulation alters sympathetic-vagal balance in domestic pigs - a pilot trial.

The disturbance of the sympathetic-vagal balance with increasing sympathetic activity and consecutive increase in cytokine release is a major threat in numerous hyperinflammatory syndromes. Therapeutic interventions that modulate the activity in the sympathetic-vagal system are suggested as an effective treatment in these incidences. The purpose of this pilot study was to investigate the effect of electrical stimulation of the gastric wall on sympathetic-vagal balance.
