Study: Discontinuing Antidepressants in Pregnancy Nearly Doubles Risk of Mental Health Emergencies
Las Vegas, NV – Pregnant patients who stopped taking their antidepressant medication during pregnancy were almost twice as likely to experience a mental health emergency compared with pregnant patients who continued taking their prescription, according to new research presented today at the Society for Maternal-Fetal Medicine (SMFM) 2026 Pregnancy Meeting™.
Mental health disorders are the largest contributor to maternal mortality in the U.S. Pregnancy can worsen existing depression, anxiety, and other psychiatric disorders. Untreated or undertreated depression during pregnancy carries health risks, such as suicide, preterm birth, preeclampsia, and low birth weight. Available data show that selective serotonin reuptake inhibitor (SSRI) antidepressant use during pregnancy is not associated with congenital anomalies, fetal growth problems, or long-term developmental problems.
Researchers from the University of Pennsylvania in Philadelphia examined de-identified records from Independence Blue Cross, a state-based private insurance database, of 3,983 patients who gave birth between January 1, 2023, and December 31, 2024. All patients were diagnosed with depression/anxiety before pregnancy and had an active prescription for an SSRI or an SNRI (serotonin norepinephrine reuptake inhibitor) antidepressant three months before pregnancy.
The study’s researchers found no difference in outpatient or emergency room visits for mental health indications prior to pregnancy between patients who continued taking their antidepressant and those who did not. However, patients who stopped taking their antidepressant therapy during pregnancy had an almost two-fold higher risk of having a mental health emergency (such as suicide risk, substance overdose, and psychosis), with peaks in the first and ninth months of pregnancy.
“These findings, while not entirely surprising to those who work with pregnant patients who suffer from mental health conditions, are so important to consider for maternal health policy,” said lead researcher Kelly B. Zafman, MD, MSCR, a maternal-fetal medicine fellow at the Hospital of the University of Pennsylvania. “This work underscores the need to take pregnant patients’ mental health seriously and to offer the full range of treatment options — including medications when clinically appropriate. Confronting the maternal mental health crisis is essential to reducing maternal morbidity and mortality in the United States.”
Oral abstract #16 “Contemporary patterns and outcomes of antidepressant discontinuation in pregnancy” will be published in the February 2026 issue of PREGNANCY, the official peer-reviewed medical journal of the Society for Maternal-Fetal Medicine.

Antibody-drug conjugate achieves high response rates as frontline treatment in aggressive, rare blood cancer
2026-02-11
Phase II study evaluates treatment for patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN), a rare, aggressive blood cancer
The antibody-drug conjugate (ADC) pivekimab sunirine (PVEK) targets the CD123 antigen, which is overexpressed in BPDCN
PVEK monotherapy demonstrated strong responses, enabling ability to proceed with stem cell transplant for high-risk subgroup of patients with BPDCN
Seventy-five percent of patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN) who were treated with the antibody-drug conjugate ...

Seashells and coconut char: A coastal recipe for super-compost
2026-02-11
In the lush landscapes of tropical agriculture, two waste products—oyster shells from the sea and coconut shells from the trees—are being combined to solve a major headache for farmers: how to turn animal manure into high-quality compost faster and more effectively. A study recently published in Carbon Research reveals that a unique "Ca-modified biochar" can act as a powerful catalyst for the composting process. Developed by a research team at Hainan University, this new material helps transform pig manure and rice straw into stable, nutrient-rich humus, significantly boosting the ...
Feeding biochar to cattle may help lock carbon in soil and cut agricultural emissions
2026-02-11
Researchers have found that most biochar fed to dairy cows survives the digestive process and remains highly stable, meaning it could be applied to fields through manure and act as a long-term carbon storage solution. The findings provide new evidence that livestock systems could play a role in climate change mitigation.
The study, recently published in Biochar, investigated what happens to biochar after it passes through the digestive system of cattle. Biochar is a carbon-rich material produced ...

The most common causes of maternal death may surprise you
2026-02-11
NEW YORK, NY--Researchers at Columbia University have found that accidental drug overdose, homicide, and suicide are the leading causes of death among pregnant and postpartum women.
The findings were published in the New England Journal of Medicine.
“Overdose and violence are not typically on our radar when it comes to thinking about approaches to reducing maternal morbidity and mortality, but these events are far more common among pregnant and postpartum women than we think,” says Hooman Azad, who led the study and is a maternal-fetal medicine fellow ...
