Electroconvulsive shocks exacerbate the heightened acoustic startle response in stressed rats.

Electroconvulsive therapy (ECT) has been successfully used in the treatment of depression, particularly when the illness is refractory to pharmacological therapy. A recent study has shown that ECT is also effective in reducing both depressive and posttraumatic stress disorder (PTSD) symptoms in patients with major depression (MDD) and co-occurring PTSD. This raises the possibility that ECT might be effective in the treatment of PTSD, a disease whose prevalence has increased substantially in recent years.

Present mood states in Brazilian night nurses.

Variations in the state of momentary emotions of Brazilian hospital nurses on day and night shifts were recorded. Ten graduate nurses working on day and night shifts in the clinical ward of hospitals completed the Present Mood States List of Engelmann at the beginning and end of the first and last days of each shift. Analysis indicated (a) nurses had a stable emotional profile, present at the working shift, and (b) variations in present mood states related to specific effects of shift work were observed when comparisons were made between the present mood states at the beginning and end of each shift duty.
