Personality and risk for postpartum depressive symptoms.

Postpartum depression (PPD) is a common childbirth complication, affecting 10-15 % of newly delivered mothers. This study aims to assess the association between personality factors and PPD. All pregnant women during the period September 2009 to September 2010, undergoing a routine ultrasound at Uppsala University Hospital, were invited to participate in the BASIC study, a prospective study designed to investigate maternal well-being. Depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) while the Depression Self-Rating Scale (DSRS) was used as a diagnostic tool for major depression. Personality traits were evaluated using the Swedish Universities Scale of Personality (SSP). One thousand thirty-seven non-depressed pregnant women were included in the study. Non-depressed women reporting high levels of neuroticism in late pregnancy were at high risk of developing postpartum depressive symptoms (PPDSs) at 6 weeks and 6 months after delivery, even after adjustment for confounders (adjusted odds ratio (aOR) = 3.4, 95 % confidence interval (CI) 1.8-6.5 and adjusted odds ratio (aOR) = 3.9, 95 % CI 1.9-7.9). The same was true for a DSRS-based diagnosis of major depression at 6 months postpartum. Somatic trait anxiety and psychic trait anxiety were associated with increased risk for PPDS at 6 weeks (aOR = 2.1, 95 % CI 1.2-3.5 and aOR = 1.9, 95 % CI 1.1-3.1), while high scores of mistrust were associated with a twofold increased risk for PPDS at 6 months postpartum (aOR 1.9, 95 % CI 1.1-3.4). Non-depressed pregnant women with high neuroticism scores have an almost fourfold increased risk to develop depressive symptoms postpartum, and the association remains robust even after controlling for most known confounders. Clinically, this could be of importance for health care professionals working with pregnant and newly delivered women.

Endoscopic transgastric procedures in anesthetized pigs: technical challenges, complications, and survival.

BACKGROUND AND STUDY AIMS: An incisionless endoscopic peroral transgastric approach to the peritoneal cavity has shown promise in animals as a potentially less invasive form of surgery. We present our experience with various endoscopic peroral transgastric procedures, reporting on the technical aspects and challenges that arose. MATERIALS AND METHODS: The following procedures were performed in 10 anesthetized pigs using a double-channel endoscope: peritoneoscopy (10 pigs), liver biopsy (one pig), cholecystectomy (six pigs), fallopian tube excision (one pig), and hysterectomy (one pig). RESULTS: All the procedures were accomplished successfully. There were six minor intraoperative complications. Complete gastric cleansing and elimination of all bacteria was found to be impossible to achieve in the porcine model. Overinflation was a common problem. The lack of adequate endoscope support was a major limitation. Safe closure of the gastrotomy incision was difficult using the available clipping devices. Six pigs made an uncomplicated recovery after a follow-up period of 4-6 weeks. Subsequent pathological examination revealed deep gastric ulceration in one animal and a gastric wall abscess in another. CONCLUSIONS: Peroral transgastric surgery is technically feasible and safe in a porcine model. Although all the procedures were performed successfully, the study highlights some technical difficulties and illustrates the need for major technical innovations and extensive animal studies in order to evaluate the merits of incisionless surgery.
