Background: Hypertensive disorders of pregnancy constitute a major cause of maternal morbidity and mortality. Pre-eclampsia/eclampsia ranks second only to haemorrhage as a specific, direct cause of maternal mortality. A number of markers have been under study for the early detection of this disease. The study aims to evaluate the predictive value of sFlt-1/PlGF ratio for preeclampsia.Methods: This study was conducted in the Department of Gynaecology and Obstetrics of ASCOMS hospital, Jammu for a period of 6 months from Jan 2019 to June 2019. 50 antenatal patients attending the outpatient department with risk factors for developing preeclampsia were enrolled in the study. Their sFlT-1/PIGF ratio was determined at gestational age of 20 weeks to 37 weeks and its predictive value was evaluated.Results: In the present study, 8 patients developed preeclampsia subsequently. The mean sFlt-1/PIGF ratio values were significantly higher in the patients who developed preeclampsia (73.5) than who did not develop the disease (26.07). The positive predictive value at 1 week was 41.66% and negative predictive value was 100%. At 4 weeks, positive predictive value was 66.66% and negative predictive value was 100%.Conclusions: The present study suggests sFlt-1/PIGF ratio values are useful marker was a predictor of preeclampsia and values >38 were associated with preeclampsia. It is more useful in ruling out preeclampsia than ruling in the disease.
Objectives: A dynamic interaction exists between respiration, cardiovascular system, and autonomic nervous regulatory mechanisms as demonstrated by respiratory sinus arrhythmia. The vascular tone might also demonstrate a similar variability during inspiration and expiration. The breathing patterns by influencing the sympathetic outflow may have an impact on the vascular tone and hence cardiovascular system at large. The present study was undertaken to assess the quiet breathing pattern and its relation with vascular tone, hemodynamics, and arterial stiffness in normal young healthy individuals. Materials and Methods: The study involved 46 young healthy adults (both males and females) aged 19–25 years. Breathing parameters included were respiratory rate (RR), inspiration time (IT), expiration time (ET), and inspiration-expiration ratio (I/E ratio). Vascular parameters included were reflection index (reflects vascular tone) and stiffness index (reflects arterial stiffness). Blood pressure (BP in mmHg) and heart rate (bpm) were measured. Results: IT and ET were almost equal with no significant difference. ET was weekly correlated with diastolic BP (r = −0.410; P = 0.058) in females but not in males. Breathing pattern was not significantly associated with vascular tone and arterial stiffness. Conclusion: IT, ET, I/E ratio, and RR were not significantly correlated with vascular tone and arterial stiffness suggesting that breathing does not influence the arterial health and function in young healthy individuals. There was a weak negative correlation between ET and diastolic BP in females but not in males, implicating the existence of fundamental differences in basic BP regulation between the sexes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
