Unplanned cesarean deliveries linked to higher risk of acute psychological stress after childbirth

Study led by Mass General Brigham investigators found that more than 1 in 4 patients who had an unscheduled cesarean delivery reported psychological stress

2026-01-15
(Press-News.org) A new study from researchers at Mass General Brigham finds that patients who undergo unscheduled or unplanned cesarean deliveries are at substantially increased risk for experiencing acute psychological stress during childbirth, with effects that can persist for months and impact maternal mental health and early bonding with infants. Results are published in Pregnancy.

The study, which followed more than 1,100 women who gave birth at Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system, found that over 1 in 4 patients who had an unscheduled cesarean delivery experienced clinically significant acute stress shortly after birth, compared with about 1 in 16 patients who delivered vaginally. Even after accounting for medical complications, prior trauma, and mental health history, individuals who had unscheduled cesareans remained more than twice as likely to experience severe stress.

“Unscheduled cesarean delivery can be lifesaving, but for some patients it is also a deeply distressing experience,” said lead investigator Sharon Dekel, PhD, MS, MPhil, of the Postpartum Traumatic Stress Disorders Research Program in the Mass General Brigham Department of Psychiatry. “Our findings show that the emotional impact of these births is common, measurable, and clinically meaningful. While most patients are resilient and won’t have a stress response, we want to make sure that people who are struggling get the resources they need.”

Stress levels were highest when cesarean delivery occurred during labor or in the presence of greater obstetric complications. Importantly, these early stress reactions were not fleeting. Women who reported high levels of acute stress shortly after childbirth were significantly more likely to develop posttraumatic stress symptoms, depression, and difficulties bonding with their infants two months later.

Dekel and her colleagues are actively working on next steps to implement a questionnaire that could help screen postpartum patients at Mass General Brigham and beyond. The findings also support growing calls for trauma-informed obstetric and postpartum care, particularly for patients who have undergone unexpected interventions during childbirth. Dekel notes that some patients may have an acute stress response but their symptoms may improve with time, which may mean it’s important to screen both immediately after birth and later.

“This study highlights the potential value of brief, low-burden screening for acute stress during postpartum hospitalization, especially after unplanned or medically complicated deliveries,” said Dekel. “Sometimes, childbirth can become an event that is emotionally loaded or a traumatic experience. But we have great ways of helping people cope, which is why we want to identify patients early and help them get connected.”

Healthy aging 2026: fresh pork in plant-forward diets supported strength and brain-health biomarkers in older adults

2026-01-15
As 2026 kicks off with a wave of “future-proof your health” messaging, new research offers practical, food-first evidence on what eating for healthy aging can look like.   In an 18-week randomized crossover feeding trial in adults 65 and older, participants following two different plant-forward dietary patterns lost weight while maintaining key markers of functional independence, grip strength and chair-rise performance, alongside improvements in multiple biomarkers tied to physical and cognitive aging.1*  The ...

Scientists identify pre-cancerous states in seemingly normal aging tissues

2026-01-15
A new single-cell profiling technique has mapped pre-malignant gene mutations and their effects in solid tissues for the first time, in a study led by investigators at Weill Cornell Medicine and the New York Genome Center. The research, published Dec. 31 in Cancer Discovery, demonstrates a practical method for simultaneously measuring specific DNA mutations and gene activity in thousands of individual cells from human tissue. The technique is expected to be useful for studying pre-cancerous cells and may ultimately guide early ...

Itaconate modifications: mechanisms and applications

2026-01-15
Itaconate, an endogenous mitochondrial metabolite produced by the enzyme aconitate decarboxylase 1 (ACOD1), has emerged as a central regulator of inflammation, innate immunity, and cellular stress responses. In a comprehensive review published in the Journal of Intensive Medicine by Yang et al, researchers summarize the rapidly expanding field of itaconate biology—highlighting its chemical reactivity, protein modification mechanisms, and therapeutic potential across infectious, inflammatory, autoimmune, and neurodegenerative diseases. Itaconate and its electrophilic ...

Potential tumor-suppressing gene identified in pancreatic cancer

2026-01-15
Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and begins in the cells lining the pancreatic duct. Accounting for more than 90% of all pancreatic cancers, PDAC is extremely difficult to treat and has a very high mortality rate. According to the Global Cancer Observatory 2022 report, pancreatic cancer is the sixth most common cancer in Japan, with over 47,000 new cases and more than 40,000 deaths, making it the fourth leading cause of cancer-related mortality in the country. In search of potential treatments, Ms. Mayuka Nii, a second-year doctoral ...

Study finds ocean impacts nearly double economic cost of climate change

2026-01-15
For the first time, a study from researchers at Scripps Institution of Oceanography at the University of California San Diego integrates climate-related damages to the ocean into the social cost of carbon— a measure of economic harm caused by greenhouse gas emissions.  When ocean damage from climate change, dubbed the “blue” social cost of carbon, is calculated, the study finds that the global cost of carbon dioxide emissions to society nearly doubles. Until now, the ocean was largely overlooked in the standard accounting of the social cost ...

Increased deciduous tree dominance reduces wildfire carbon losses in boreal forests

2026-01-15
As climate change drives more frequent and severe wildfires across boreal forests in Alaska and northwestern Canada, scientists are asking a critical question: Will these ecosystems continue to store carbon or become a growing source of carbon emissions? New research published this week shows that when forests shift from coniferous—consisting mostly of pines, spruces and larches—to deciduous—consisting mostly of birches and aspens—they could release substantially less carbon when they burn. The National Science Foundation-funded study, led by researchers from the Center for Ecosystem Science and Society (ECOSS) at Northern Arizona University and published in ...

Researchers discover how a respiratory bacterium obtains essential lipids from the human body and targets fat-rich tissues

2026-01-15
Barcelona, January 15, 2026. A multidisciplinary team has uncovered a key mechanism that allows the human bacterium Mycoplasma pneumoniae—responsible for atypical pneumonia and other respiratory infections—to obtain cholesterol and other essential lipids directly from the human body. The discovery, published in Nature Communications, was co-led by Dr. Noemí Rotllan, from the Sant Pau Research Institute (IR Sant Pau) and the Center for Biomedical Research in Diabetes and Associated Metabolic Disorders (CIBERDEM); Dr. Marina Marcos, from the Autonomous University of Barcelona (UAB); and Dr. David Vizarraga, from the Institute of Molecular Biology ...

Locust swarms destroy crops. Scientists found a way to stop that

2026-01-15
“They’re very destructive when there's a lot of them, but one-on-one, what's not to love?” says Arianne Cease. She’s talking about locusts. As the director of Arizona State University’s Global Locust Initiative, Cease has a healthy admiration for these insects, even as she studies ways to manage locust swarms and prevent the destruction they cause. Locust swarms, which may conjure images of biblical plagues and ancient famines, remain a serious problem worldwide. They can destroy crops across entire regions, ruin people’s livelihoods, ...
