Physiological changes during pregnancy reduce effects of bipolar drugs

New Northwestern Medicine- research offers one of the first in-depth studies of how physiological changes during pregnancy reduce the effects of a commonly used drug to treat bipolar disorder, making women more vulnerable to recurring episodes. The new findings will help psychiatrists and physicians prevent bipolar manic and depressive symptoms during pregnancy, which are risky for the health of the mother and her unborn child.

Study in mice may help in the development of more effective treatments for anxiety disorders

Excessive fear can develop after a traumatic experience, leading to anxiety disorders such as post-traumatic stress disorder and phobias. During exposure therapy, an effective and common treatment for anxiety disorders, the patient confronts a fear or memory of a traumatic event in a safe environment, which leads to a gradual loss of fear.

Study looks at the feasibility of Xpert test for TB in real-life clinical setting in southern Africa

The first randomised trial to measure the impact of the rapid Xpert MTB/RIF test for tuberculosis in a real-life clinical setting finds that it can be accurately performed by a non-specialist with minimal training, improves same-day diagnosis and time to starting treatment, and increases the number of people who start treatment after testing positive on day 1 by 50%, compared with conventional TB diagnostics.
