Beetroot juice, exercise, and cardiovascular function in women planning to conceive.

OBJECTIVE: Prepregnancy optimization of cardiovascular function may reduce the risk of pre-eclampsia. We aimed to assess the feasibility and effect of preconception cardiovascular monitoring, exercise, and beetroot juice on cardiovascular parameters in women planning to conceive. DESIGN AND METHOD: Prospective single-site, open-label, randomized controlled trial. Thirty-two women, aged 18-45 years, were allocated into one of four arms (1 : 1 : 1 : 1): exercise, beetroot juice, exercise plus beetroot juice and no intervention for 12 weeks. Blood pressure (BP) was measured at home daily. Cardiac output ( CO ) and total peripheral resistance (TPR) were assessed via bio-impedance. RESULTS: Twenty-nine out of 32 (91%) participants completed the study. Adherence to daily BP and weight measurements were 81% and 78%, respectively ( n  = 29). Eight out of 15 (53%) of participants did not drink all the provided beetroot juice because of forgetfulness and taste. After 12 weeks, exercise was associated with a reduction in standing TPR (-278 ±â€Š0.272 dynes s cm -5 , P  < 0.05), and an increase in standing CO (+0.88 ±â€Š0.71 l/min, P  < 0.05). Exercise and beetroot juice together was associated with a reduction in standing DBP ( 7 ±â€Š6 mmHg, P  < 0.05), and an increase in standing CO (+0.49 ±â€Š0.66 l/min, P  < 0.05). The control group showed a reduction in standing TPR ( 313 ±â€Š387 dynes s cm -5 ) and standing DBP ( 8 ±â€Š5mmHg). All groups gained weight. CONCLUSION: Exercise and beetroot juice in combination showed a signal towards improving cardiovascular parameters. The control group showed improvements, indicating that home measurement devices and regular recording of parameters are interventions in themselves. Nevertheless, interventions before pregnancy to improve cardiovascular parameters may alter the occurrence of hypertensive conditions during pregnancy and require further investigation in adequately powered studies.

Manual perineal protection: The know-how and the know-why.

Manual perineal protection is an obstetric intervention to mitigate the risk of perineal trauma. There are two effective techniques (Finnish and Viennese) with minor but distinctive differences in between them. The main aim of this study was to explore clinicians' knowledge about the manual perineal protection technique they use. The study took place in three maternity units that support manual perineal protection policy in three European countries (Czech Republic, Slovenia and the UK). Our study demonstrated that the majority of participants are aware of the concept of manual perineal protection. However, there were significant differences between staff responses regarding their views and experience with manual perineal protection in general. Less than 6% of respondents were able to provide an accurate account of the actual maneuvers they perform when manually protecting the perineum. Although this is not necessarily synonymous with suboptimal performance, it highlights the potential need to give more attention to the theory that underpins the technical skill in manual perineal protection training programs.
