Variability of blood pressure (BP) has been reported to be related to worse cardiovascular outcomes. We examined the impact of daytime systolic BP variability on left ventricular (LV) function and arterial stiffness in hypertensive patients. ⋯ Increased BP variability was associated with LV mass and dysfunction, as well as arterial stiffness, suggesting that BP variability may be an important determinant of target organ damage in hypertensive patients.

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.
