The relation between panic disorder and suicidal behavior has been surrounded by perennial controversy. A significant number of reports suggest that PD is associated with suicidal behavior. Alternatively, it has been proposed that comorbid depression may account for the increased suicidality identified in this population. ⋯ In this clinical outpatient sample, the association between panic disorder and suicidal behavior was primarily explained by comorbidity with depressive disorders. No differences were observed between different groups for measures of severity of the suicidal behavior. Physicians should be aware of these associations when assessing adults with panic disorder for suicidality.

Previous research has suggested that chronic pain patients might be particularly vulnerable to the effects of negative mood during information processing. However, there is little evidence for abnormal brain processing of affective and sensory pain-related information in chronic pain. Behavioral and brain responses, to pain descriptors and pleasant words, were examined in chronic pain patients and healthy controls during a self-endorsement task. ⋯ These data support the notion of abnormal information processing in chronic pain patients, which might be characterized by a lack of dissociation between sensory and affective components of pain-related information, and by an exaggerated rumination over word meaning during the encoding of self-referent information about pain.

Intimate partner violence (IPV) is prevalent in most parts of the world. It is also prevalent during pregnancy. ⋯ The experience of intimate partner violence and its mental health consequences are quite prevalent in India which is a culture where gender disparities are normative and pregnancy is a particularly vulnerable period.

The detection and diagnosis of present or past hypomanic episodes is of key importance for the differential diagnosis between depressive disorders and type II bipolar disorder. However, there are few instruments available to satisfactorily screen for the latter condition. The Hypomania Symptom Checklist-32 (HCL-32) is a self-applied questionnaire with 32 hypomania items and 8 severity and functional impact items which is being developed in several European countries for this purpose. Our aim was to develop and validate the psychometric properties of the HCL-32 scale in Spain in patients with bipolar disorder and to compare its properties with other instruments available for the detection of bipolar II disorder. ⋯ The Spanish version of the HCL-32 has good psychometric properties and sufficient sensitivity and specificity, detecting 8 out of every 10 patients with BD. The HCL-32 is a useful screening tool of patients with bipolar disorder in clinical settings. In its present form it adequately discriminates between bipolar and unipolar or healthy subjects, but not between BD I and BII.

Randomized Controlled Trial Comparative Study
Go-no-go task performance improvement after anodal transcranial DC stimulation of the left dorsolateral prefrontal cortex in major depression.
We recently showed that repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex (DLPFC) can affect the performance in an affective go-no-go (AGN) task. We aimed to extend this previous investigation testing whether one session of anodal transcranial direct current stimulation (tDCS) of the left DLPFC, as compared with anodal occipital and sham tDCS, affects this AGN task performance. ⋯ Our findings suggest that left DLPFC activity is associated with positive emotional processing, confirming and extending results of previous studies that associated right DLPFC and orbito-frontal cortex activity with emotional processing. Furthermore the effects of tDCS on mood and cognition seem to be independent in major depression. These lines of evidence together shed light on the neural circuitry involved with emotional processing in major depression.
