Preventing pregnancy loss with aspirin and low-molecular-weight heparin
Low-dose aspirin combined with low-molecular-weight heparin (LMWH) during pregnancy is just as safe and effective as aspirin with unfractionated heparin (UFH) for preventing recurrent pregnancy loss due to antiphospholipid syndrome, according to a prospective, controlled, multicenter pilot study.
Low-dose aspirin combined with low-molecular-weight heparin (LMWH) during pregnancy is just as safe and effective as aspirin with unfractionated heparin (UFH) for preventing recurrent pregnancy loss due to antiphospholipid syndrome, according to a prospective, controlled, multicenter pilot study.
The study included 50 women. Of 25 who received LMWH, 21 (84%) delivered a viable infant and 4 (16%) miscarried. Among 25 who received UFH, 20 (80%) delivered a viable infant and five (20%) miscarried. The differences were not statistically significant. No major bleeding episodes occurred during pregnancy or birth, and no cases of deep venous thrombosis, thrombocytopenia, preeclampsia, gestational diabetes, or bone fractures occurred in either group.
The investigators concluded that a large, randomized trial is now needed to further determine any differences in outcomes.

Major congenital malformations not linked to first trimester tetracycline use
November 20th 2024A large population-based study found that first-trimester tetracycline exposure does not elevate the risk of major congenital malformations, though specific risks for nervous system and eye anomalies warrant further research.
