Women face significantly higher risks of depression and psychosis in the weeks following childbirth, according to a major new analysis published in the journal Molecular Psychiatry. The study, which examined data from nearly 1.8 million births in Sweden between 2003 and 2019, reveals that while mental health diagnoses tend to decrease during pregnancy, they rise sharply after delivery. Researchers from Karolinska Institutet found this pattern particularly pronounced for depression and psychosis, highlighting a critical period of vulnerability for new mothers.

The analysis shows that the risk of depression is approximately 20 percent higher during weeks five to 15 postpartum compared to the year before pregnancy. For psychosis, the risk is even more dramatic—six to seven times higher in the first five weeks after childbirth and twice as high through week 20. Unlike temporary "baby blues," postpartum psychosis is a serious condition characterized by delusions, hallucinations, mania, low mood, and confusion, though women can achieve full recovery with proper treatment.

Notably, the study also found that the risk of suicide attempts decreases after childbirth, suggesting a complex interplay of factors affecting maternal mental health. Women were less likely to be diagnosed with anxiety, stress, or substance abuse during or after pregnancy than beforehand, which researchers attribute to a combination of biological and lifestyle changes. Increased medical visits during pregnancy may also lead to earlier identification of mental health issues before they escalate.

The introduction of national guidelines for screening pregnant women for depression in Sweden in 2020 has provided opportunities for earlier detection and intervention. By comparing women who gave birth before and after the guidelines were implemented, researchers observed potential benefits of systematic screening. The findings underscore the importance of targeted mental health support during the postpartum period to address the heightened risks identified in the study.

TGS, the Oslo-based energy data provider, has been awarded a significant ocean bottom node (OBN) acquisition contract in the Gulf of Mexico, marking another strategic win in one of the company's core markets. The 4D monitor survey is scheduled to commence in the fourth quarter of 2025 and will span approximately four and a half months. This contract represents continued confidence in TGS's capabilities from the international oil company client, though the specific customer identity remains undisclosed.

The contract was notably absent from TGS's booked position disclosed in the company's second quarter 2025 presentation, indicating a recent acquisition for the seismic data specialist. The Gulf of Mexico remains a critical region for offshore energy production, and 4D seismic monitoring plays an essential role in optimizing reservoir management and production efficiency for major operators in the region.

Kristian Johansen, CEO of TGS, emphasized the significance of securing business from repeat customers, stating that the client values TGS's OBN technology and proven track record of project execution. "The client is confident we will deliver high-quality data and insights to optimize production from one of their highest producing facilities in the Gulf of Mexico," Johansen commented, highlighting the operational importance of the project for the customer's production optimization efforts.

TGS's expertise in OBN technology positions the company as a trusted partner for international oil companies seeking to maximize recovery from existing assets. The 4D seismic approach allows operators to monitor reservoir changes over time, providing critical data for production optimization decisions. This latest contract win reinforces TGS's strong position in the Gulf of Mexico market and demonstrates the ongoing demand for advanced seismic monitoring solutions in mature offshore basins.
