AbstractPreeclampsia (PE) and fetal growth restriction (FGR) are both placenta-mediated disorders with unclear pathogenesis. Metabolomics of maternal and fetal pairs might help in understanding these disorders. We recruited prospectively pregnancies with normotensive FGR, PE without FGR, PE + FGR and uncomplicated pregnancies as controls. Nuclear magnetic resonance metabolomics were applied on plasma samples collected at delivery. Advanced lipoprotein, glycoprotein and choline profiling was performed using the Liposcale test. The software package Dolphin was used to quantify 24 low-molecular-weight metabolites. Statistical analysis comprised the comparison between each group of complicated pregnancies versus controls, considering 5% false discovery rate correction. Lipid profiles were altered in accordance with the clinical presentation of these disorders. Specifically, PE mothers and FGR fetuses (with or without FGR or PE, respectively) exhibited a pro-atherogenic and pro-inflammatory profile, with higher concentrations of triglycerides, remnant cholesterol (VLDL, IDL) and Glc/GalNAc-linked and lipid-associated glycoproteins compared to controls. Low-molecular-weight metabolites were extensively disturbed in preeclamptic mothers, with or without FGR. Growth restricted fetuses in the presence of PE showed changes in low-molecular-weight metabolites similar to their mothers (increased creatine and creatinine), while normotensive FGR fetuses presented scarce differences, consistent with undernutrition (lower isoleucine). Further research is warranted to clarify maternal and fetal adaptations to PE and FGR.

Abstract Funding Acknowledgements Type of funding sources: None. Background- Low molecular weight heparin (LMWH) and direct oral anticoagulants (DOACs) have been proven to be more effective in the management of venous thromboembolism (MVTE). The efficacy and safety of LMWH or DOACs in treatment of recurrent or malignancy induced VTE is not studied in literature. Objective To compare the efficacy and safety of LMWH and  DOACs in the management of malignancy induced  VTE Methods- Electronic databases ( PubMed, Embase, Scopus, Cochrane) were searched from inception to November  28th, 2020. Dichotomous data was extracted for prevention of VTE and risk of major bleeding in patients taking either LMWH or DOACs. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p < 0.05.  Results- Three studies with 2607 patients (DOACs n = 1301 ; LMWH n = 1306) were included in analysis. All the study population had active cancer of any kind diagnosed within the past 6 months. Average follow-up period for each trial was 6 months. Patients receiving DOACs have a lower odds of recurrence of MVTE as compared to LMWH( OR 1.56; 95% CI 1.17-2.09; P = 0.003, I2 = 0). There was no significant difference in major bleeding among patients receiving LMWH or DOACs  (OR-0.71, 95%CI 0.46-1.10, P = 0.13, I2 = 22%) (Figure 1). We had no publication bias in our results (Egger’s regression p > 0.05). Conclusion- DOACs are superior to LMWH in prevention of MVTE and have similar major bleeding risk as that of LMWH.

Oncourologic diseases are accompanied by a risk for subsequent venous thromboembolic complications, which are rated the most dangerous in terms of thrombogenic effect. The article presents a review of the clinical studies of efficacy and safety, and the experience in using of modern low-molecular-weight heparins in clinical practice - drugs of choice for the prevention of venous thromboembolic complications in cancer patients. Particular attention is paid to Bemiparin - a new second-generation low-molecular-weight heparin with a significant antithrombotic effect and improved pharmacological parameters that allow it to be successfully used in patients with impaired renal function in oncourological practice.
