Children of depressed mothers are at elevated risk to develop behavioral problems. Besides maternal depression, other risk factors like interpersonal functioning, are discussed. The object of this study was to investigate the predictive value of the maternal variables depression, partnership, social support, and parenting for internal and external behavioral problems of the children. ⋯ These findings suggest the need for intervention programs which focus on the parenting and the partnership of the mothers. More research with independent assessment is needed.

Posttraumatic stress disorder (PTSD) is common in refugees but its association with longer-term psychosocial dysfunction remains unclear. We examined whether a subgroup of refugees with comorbid PTSD and depression were at particularly high risk of disability. We also investigated whether specific trauma experiences were linked to this comorbid pattern. ⋯ The combination of life threat and traumatic loss may be particularly undermining to the psychological well-being of refugees and consequent comorbidity of PTSD and depression may be associated with longer-term psychosocial dysfunction. The findings raise the question whether the comorbid pattern identified should be given more recognition as a core posttraumatic affective disorder.

Experts have debated the influence of mental illness on decision-making capacity. This paper reviews concepts of decision-making capacity and existing research on the influence of mental illness on capacity to consent to research. We propose how bipolar disorder, especially mania, may have an effect on consent capacity. ⋯ Mania may impact freedom to decide, yet paradoxically, manic patients may be less influenced by others and less vulnerable to coercion, undue influence and undue incentives compared to patients without mental illness. We suggest that in patients with mood disorders, the legal standard of appreciation be thoroughly probed during the consent procedure. Studies of the effect of mania and depression on consent capacity and voluntarism are needed in order to develop processes that increase safeguards in the informed consent process.

(E)-4-Hydroxy-2-nonenal (HNE) is a highly electrophilic end-product of lipid peroxidation. Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of endothelial nitric oxide synthase (NOS). ADMA is metabolised by dimethylarginine dimethylaminohydrolase (DDAH). DDAH contains a nucleophilic cysteine residue in its active site. There is an increase in lipid peroxidation in major depression. Major depression is associated with the development of coronary heart disease (CHD) and greatly increases morbidity and mortality. There is an increase in circulating ADMA in CHD and vascular risk factors. ⋯ There is an increase in circulating HNE in major depression. HNE inactivates the cysteine residue in the active site of endothelial DDAH leading to the accumulation of ADMA in the circulation. The ADMA then decreases the production of eNOS. This could reduce the amount of NO diffusing from cerebral blood vessels to nearby neurons and influence the release of neurotransmitters. ADMA also constricts cerebral blood vessels and may contribute to the decreased regional perfusion in major depression. The accumulation of ADMA could explain the increased risk of CHD in major depression. The preservation of DDAH activity and the reduction of ADMA accumulation may represent a novel therapeutic approach to the treatment of major depression.

Postpartum depression is a major health issue for many women around the world with well-documented negative health consequences for the mother, child and family. While research has demonstrated the amenability of postpartum depression to treatment, there is preliminary evidence suggesting maternal mood in the immediate postpartum period may be predictive of postpartum depression such that secondary preventive interventions may be implemented. ⋯ The EPDS administered in the 1st week postpartum was predictive of maternal mood at 4 and 8 weeks postpartum. To identify mothers at high risk for postpartum depression, health care professionals could consider screening all new mothers in the immediate postpartum period such that secondary preventive interventions may be implemented.
