Optimal use of intravenous tranexamic acid for hemorrhage prevention in pregnant women.
Every 2 minutes, there is a pregnancy-related death worldwide, with one-third caused by severe postpartum hemorrhage. Although international trials demonstrated the efficacy of 1000 mg tranexamic acid in treating postpartum hemorrhage, to the best of our knowledge, there are no dose-finding studies of tranexamic acid on pregnant women for postpartum hemorrhage prevention. ⋯ Although large randomized trials are necessary to support the clinical efficacy of tranexamic acid for prophylaxis, we propose an optimal dose of 600 mg in future tranexamic acid efficacy studies to prevent postpartum hemorrhage.

Multicenter StudyPregnant women with severe or critical coronavirus disease 2019 have increased composite morbidity compared with nonpregnant matched controls.
In March 2020, as community spread of severe acute respiratory syndrome coronavirus 2 became increasingly prevalent, pregnant women seemed to be equally susceptible to developing coronavirus disease 2019. Although the disease course usually appears mild, severe and critical cases of coronavirus disease 2019 seem to lead to substantial morbidity, including intensive care unit admission with prolonged hospital stay, intubation, mechanical ventilation, and even death. Although there are recent reports regarding the impact of coronavirus disease 2019 on pregnancy, there is a lack of information regarding the severity of coronavirus disease 2019 in pregnant vs nonpregnant women. ⋯ Pregnant women with severe and critical coronavirus disease 2019 are at an increased risk for certain morbidities when compared with nonpregnant controls. Despite the higher comorbidities of diabetes and hypertension in the nonpregnant controls, the pregnant cases were at an increased risk for composite morbidity, intubation, mechanical ventilation, and intensive care unit admission. These findings suggest that pregnancy may be associated with a worse outcome in women with severe and critical cases of coronavirus disease 2019. Our study suggests that similar to other viral infections such as severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, pregnant women may be at risk for greater morbidity and disease severity.

Perinatal outcomes in women with elevated blood pressure and stage 1 hypertension.
Hypertension was redefined in 2017 with lower diagnostic thresholds; elevated blood pressure is defined as systolic blood pressure of 120 to 129 mm Hg with diastolic blood pressure of <80 mm Hg and stage 1 hypertension as systolic blood pressure of 130 to 139 mm Hg or diastolic blood pressure of 80 to 89 mm Hg. These guidelines did not include pregnant women. There is limited information on stage 1 hypertension and pregnancy outcomes. ⋯ Our study demonstrates that elevated blood pressure and stage 1 hypertension, using the 2017 American College of Cardiology and the American Heart Association guideline definition, are associated with increased maternal and neonatal risk. This group of women warrants further investigation to determine whether pregnancy management can be altered to reduce maternal and neonatal morbidity.

ReviewThe coronavirus disease 2019 vaccine in pregnancy: risks, benefits, and recommendations.
The coronavirus disease 2019 has caused over 2 million deaths worldwide, with over 412,000 deaths reported in Unites States. To date, at least 57,786 pregnant women in the United States have been infected, and 71 pregnant women have died. ⋯ A review of maternal and neonatal coronavirus disease 2019 morbidity and mortality data along with perinatal vaccine safety considerations are presented to assist providers with shared decision-making regarding vaccine administration for this group, including the healthcare worker who is pregnant, lactating, or considering pregnancy. The coronavirus disease 2019 vaccine should be offered to pregnant women after discussing the lack of safety data, with preferential administration for those at highest risk of severe infection, until safety and efficacy of these novel vaccines are validated.
