Associated factors of blood transfusion for Caesarean sections in pure placenta praevia pregnancies.
This study aimed to evaluate associated factors of blood transfusion for Caesarean sections in pure placenta praevia pregnancies. ⋯ Previous Caesarean section, anterior placentation, major placenta praevia, preoperative bleeding of more than 250 mL, preoperative anaemia and emergency Caesarean section were independent factors that increased the risk of blood transfusion for Caesarean section in pure placenta praevia pregnancies.

Parkinson's disease (PD) is associated with cognitive decline but little is known about frontal-subcortical and posterior cortical cognitive functioning in patients with PD. The present study was designed to: (a) compare frontal and posterior cognitive functioning between patients with PD and healthy controls; (b) determine the effect of levodopa (L-dopa) on frontal-subcortical and posterior cortical cognitive functions; and (c) identify predictors of cognitive functions in patients with PD. ⋯ L-dopa medication improves frontal-subcortical and posterior cortical cognitive functioning in patients with PD. Disease duration is a marker of cognitive decline in PD.

Self-expanding metal stents (SEMS) can be used as a bridge to surgery (BTS) or for palliation in the treatment of malignant large bowel obstruction. This case series evaluates the short-term outcomes of SEMS and success rates over time. ⋯ SEMS are a safe and effective way of relieving malignant large bowel obstruction, including those that are proximal. The improvement in success over time reflects the importance of having an experienced endoscopist carry out the procedure to ensure optimum success rates.
