The peripartum period involvement in the development of post-partum depression. A prospective cohort study.

Purpose: This study explores postpartum depression (PPD) in women who screened negative in mid-pregnancy to assess the impact of the peripartum period on the development of depressive symptoms.

Methods: A prospective cohort study was carried out in two facilities in Argentina. The Edinburgh postnatal depression scale (EPDS) scale was applied to pregnant women between weeks 20-24 gestation, and those screening negative (<10) were included in the cohort.

Factors associated with depression during pregnancy in women from a low socioeconomic level: A hierarchical model approach.

The objectives of this cross-sectional study were to estimate the prevalence of depressive symptoms and affective disorders during pregnancy in a maternity hospital in Argentina and to explore potential risk factors. Symptoms of depression were measured with the Edinburgh Postnatal Depression Scale (EPDS), and the Mini International Neuropsychiatric Interview (MINI) for diagnosis at mid-pregnancy. 50.

Vasoconstrictor effects of 8-iso-prostaglandin E2 and 8-iso-prostaglandin F(2alpha) on human umbilical vein.

The present study was undertaken to determine whether 8-iso-prostaglandin E2 and 8-iso-prostaglandin F(2alpha) posses contractile action on human umbilical vein and to evaluate the possible involvement of prostanoid TP receptors in this effect. Human umbilical vein rings were mounted in organ baths and concentration-response curves to 8-iso-prostaglandin E2 or 8-iso-prostaglandin F(2alpha) were constructed. Both isoprostanes evoked concentration-dependent contraction.

Pharmacological characterization of prostanoid receptors mediating vasoconstriction in human umbilical vein.

1. This study was undertaken to characterize pharmacologically the prostanoid receptor subtypes mediating contraction in human umbilical vein (HUV). 2.
