One of the most serious complications of pregnancy is preeclampsia, a condition that affects pregnant women worldwide. This condition can be dangerous for both the mother and the baby, making it early detection and monitoring. A recent study, Posted on PLOS MedicineHe examined the effectiveness of forecasts in evaluating the risk of adverse maternal results for women with preeclampsia.
What is preeclampsia?
Preeclampsia is a disorder associated with pregnancy characterized by high blood pressure and signs of damage to organs such as the liver and kidneys. It usually occurs after the 20th week of pregnancy and can lead to serious complications, including epileptic seizures (Eclampsia), stroke and organ failure. Preeclampsia affects 5-7% of pregnancies worldwide and is the main cause of parent and fetal morbidity and mortality.
The symptoms of preeclampsia include:
- High blood pressure (over 140/90 mmHg)
- Swelling, especially in the hands and face
- Serious headaches
- Vision problems (blurred vision, seeing points)
- Shortness of breath
- Protein in urine (detected through laboratory tests)
If left untreated, preeclampsia can proceed with eclampsia, which includes life -threatening seizures.
According to global data, preeclampsia complicates about 2-8% of pregnancy. It is more common in the first pregnancies, women over 35 years of age, those who carry multiple and people with pre -existing conditions such as hypertension, diabetes or kidney disease. It also disproportionately affects black women and those with limited access to health care.
How does preeclampsia affect pregnancy?
Preeclampsia can have serious consequences for both the mother and the baby. Can lead to:
- Early Birth: Many women with severe preeclampsia have to deliver early to protect their health and their baby.
- Limited development of the fetus: High blood pressure reduces blood flow to the placenta, limiting the baby’s oxygen and nutrients.
- Placental cut: The placenta can be disconnected from the uterus prematurely, causing severe bleeding and possible damage to the baby.
- Organ damage: Preeclampsia can affect mother’s kidneys, liver, brain and cardiovascular system, increasing the risk of long -term health problems.
Researchers have developed models to predict which women with preeclampsia are at a higher risk of serious complications. This study examined two tools: Piers-ML (mechanical learning-based model) and Fullpiers (logical reflux model). These models evaluate various health factors and calculate the likelihood of adverse maternal effects, including death, organ deficiency (heart, lungs, kidneys, liver, etc.) and placental complications.
The study analyzed data from 8,843 women diagnosed with preeclampsia in many countries, including America, sub -Saharan Africa, South Asia, Europe and Oceania. Participants had an average age of 31 years of age and were diagnosed at an average age of 35.79 weeks. The researchers used this data to evaluate how well the Piers-Ml and Fullpiers models could predict serious maternal complications in a two-week period after being admitted to the hospital.
The findings showed that both models were more effective in predicting dangers within the first 48 hours after a woman was admitted to the hospital. The Piers-M model, which uses mechanical learning, is best performed on the first day, but its accuracy has been reduced over time. The study revealed that after 48 hours, the ability of both models to distinguish between high -risk and low risk patients have deteriorated significantly. Over time, as women’s conditions have changed, the predictive power of these models faded, emphasizing the need for continuous monitoring and not with exclusive dependence on these tools.
The study also categorized women into “very high risk”, “high risk”, “moderate risk”, “low -risk” and “very low -risk” groups based on probability ratios. Women in the very high risk category were much more likely to have serious complications within 48 hours. However, the study found that even those in lower risk categories required ongoing evaluations, as conditions could be unexpectedly changed. Dynamic displacements were observed at risk levels, emphasizing the need for doctors to adapt the treatment plans based on real -time patient data and not on fixed model predictions.
In addition, the study examined the decision curve analyzes to determine whether the use of these models for treatment decisions provided clinical benefits. The results showed that while Piers-ML had an advantage on the first day, its benefit was reduced over time, indicating that serial predictions should be carefully approached. Clinicians who use these models for ongoing evaluations should interpret the results with increasing uncertainty as pregnancy progresses.
What does this mean to the expected mothers
Early detection and hospitalization. If you have preeclampsia, searching for medical care early can significantly improve the results. Doctors use carefully risk models, recognizing their limitations beyond the original evaluation. Continuing monitoring is vital, as preeclampsia can exacerbate unexpectedly. Even if an initial assessment is at low risk, regular controls, blood pressure monitoring and fetal estimates remain significant. Expected mothers should trust their symptoms – if they have a deterioration of headaches, visual impairments or edema, they should immediately report them to the healthcare provider.
