Swiss Innovation Offers Hope in Predicting and Preventing Premature Births
Each year, an estimated 15 million babies are born prematurely worldwide. Now, a groundbreaking device developed in Switzerland is offering a potential pathway to reduce these numbers and improve outcomes for both mothers and infants. Premature birth, defined as before 37 weeks of gestation, carries significant risks, including respiratory problems and cerebral hemorrhages for newborns.
The Role of Cervical Rigidity
Researchers have long suspected a link between the rigidity of the cervix (the lower part of the uterus) and the risk of premature labor. Sabrina Badir, a biomechanics expert, has spearheaded research demonstrating that women with a more flexible cervix are more likely to deliver prematurely. “In clinical studies, we have shown that women whose cervix is more supple give birth more often prematurely,” Badir explains.
The cervix acts as a barrier during pregnancy, remaining closed to support the developing baby. Premature opening of the cervix can lead to early delivery. Although the connection was known, a standardized method for measuring cervical rigidity was lacking – until now.
Pregnolia: A Recent Device for Early Detection
During her doctoral research at the Swiss Federal Institute of Technology in Zurich (EPFZ), Sabrina Badir developed a device to accurately measure cervical rigidity. She subsequently founded Pregnolia, a start-up dedicated to bringing this technology to clinical practice. Currently, the device is being tested for its ability to differentiate between practice contractions and the onset of actual labor when used during hospital admission.
Beyond Reactive Measurement: Predicting Risk Earlier
Badir’s ambitions extend beyond simply reacting to signs of impending labor. The goal is to utilize the device earlier in pregnancy – as early as the 20th week – to proactively identify women at risk of premature birth. “We have found that it is already possible to observe differences in cervical rigidity from the 20th week of pregnancy,” she notes.
Currently, ultrasound is the primary method for assessing risk, but it isn’t always effective. Early detection is crucial, allowing medical professionals to implement interventions such as closer monitoring, stress reduction techniques, medication, or even surgical procedures to delay delivery. Despite these efforts, the rate of premature births in Switzerland has remained stable in recent years.
Funding and the Future of Women’s Health
Pregnolia has secured 15 million Swiss francs in investment, including a recent 2 million franc contribution from the European Union. This funding is particularly significant given that women’s health receives a disproportionately small share of healthcare investment – only 6% of private health investments globally, according to the World Economic Forum.
Badir hopes this investment will catalyze further research and development, ultimately leading to targeted therapies and medications to address the underlying causes of premature birth.
Prematurity Rates in Switzerland and Beyond
In Switzerland, approximately 6-7% of babies are born prematurely. This translates to roughly 200-300 premature births annually in the Valais region alone. Globally, premature birth affects around one in ten babies.
Support for Families Affected by Prematurity
Organizations like Né Trop Tôt provide support and guidance to parents of premature infants hospitalized in neonatal units.
Did you know?
Premature babies born before 32 weeks of gestation are at the highest risk of complications, with a 10-15% mortality rate and a significant chance of long-term health issues.
FAQ
Q: What is considered a premature birth?
A: A premature birth is defined as delivery before 37 weeks of gestation.
Q: What are the main risks associated with premature birth?
A: Premature babies are at risk of respiratory problems, cerebral hemorrhages, and long-term developmental challenges.
Q: How does the new device work?
A: The device measures the rigidity of the cervix, which has been linked to the risk of premature labor.
Q: Is this device currently available for use in hospitals?
A: The device is currently undergoing further testing and is not yet widely available for routine clinical use.
Q: Where can parents uncover support if their baby is born prematurely?
A: Organizations like Né Trop Tôt offer support and resources for families of premature infants.
Pro Tip: If you are pregnant and have concerns about premature labor, discuss them with your healthcare provider. Early detection and intervention can significantly improve outcomes.
