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 ± 0.272 dynes s cm -5 , P < 0.05), and an increase in standing CO (+0.88 ± 0.71 l/min, P < 0.05). Exercise and beetroot juice together was associated with a reduction in standing DBP ( 7 ± 6 mmHg, P < 0.05), and an increase in standing CO (+0.49 ± 0.66 l/min, P < 0.05). The control group showed a reduction in standing TPR ( 313 ± 387 dynes s cm -5 ) and standing DBP ( 8 ± 5mmHg). 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.

OBJECTIVES: Current antenatal care largely relies on widely spaced appointments, hence only a fraction of the pregnancy period is subject to monitoring. Continuous monitoring of physiological parameters could represent a paradigm shift in obstetric care. Here, we analyse the data from daily home monitoring in pregnancy and consider the implications of this approach for tracking pregnancy health. METHODS: Prospective feasibility study of continuous home monitoring of blood pressure, weight, heart rate, sleep and activity patterns from the first trimester to 6 weeks postpartum. RESULTS: Fourteen out of 24 women completed the study (58%). Compared to early pregnancy [week 13, median heart rate (HR) 72/min, interquartile range (IQR) 12.8], heart rate increased by week 35 (HR 78/min, IQR 16.6; P = 0.041) and fell postpartum (HR 66/min, IQR 11.5, P = 0.021). Both systolic and diastolic blood pressure were lower at mid-gestation (week 20: SBP 103 mmHg, IQR 6.6; DPB 63 mmHg, IQR 5.3 P = 0.005 and P = 0.045, respectively) compared to early pregnancy (week 13, SBP 107 mmHg, IQR 12.4; DPB 67 mmHg, IQR 7.1). Weight increased during pregnancy between each time period analyzed, starting from week 15. Smartwatch recordings indicated that activity increased in the prepartum period, while deep sleep declined as pregnancy progressed. CONCLUSION: Home monitoring tracks individual physiological responses to pregnancy in high resolution that routine clinic visits cannot. Changes in the study protocol suggested by the study participants may improve compliance for future studies, which was particularly low in the postpartum period. Future work will investigate whether distinct adaptative patterns predate obstetric complications, or can predict long-term maternal cardiovascular health.

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.

AIMS: To examine biological materials (blood, urine, cerebrospinal fluid) of patients with suspected leptospirosis using real-time PCR for detecting the gene that codes the superficial LipL32 lipoprotein, and to evaluate the contribution of the real-time PCR method for the laboratory diagnosis of the acute form of leptospirosis. MATERIAL AND METHODS: During the monitored period of April 2010 - December 2011, a total of 340 biological materials samples were examined (177x blood plasma, 88x urine, 68x, cerebrospinal fluid, 6x bronchoalveolar lavage and 1x sputum) from 216 patients with suspected leptospirosis using real-time PCR LipL32 gene detection. RESULTS: From the mentioned 216 patients suspected of leptospirosis, 8 patients were evaluated as being PCR LipL32 positive, from which 14 positive biological materials originated (9 x urine, 4x blood and 1x liquor). CONCLUSION: As demonstrated in the study, the real-time PCR method for detecting the gene for the superficial lipoprotein LipL32 is an appropriate, quick and reliable method for the diagnosis of the acute form of leptospirosis.
