Studying the Prediction of Spontaneous Preterm Birth Using Quantitative Fetal Fibronectin (fFN) for Threatened Preterm Labor: A Pilot Study.
Objective
To determine whether the quantitative value of fetal fibronectin (fFN) can predict preterm birth (PTB) in women with Threatened Preterm Labor.
Design
A retrospective study carried out in WWRC between the years 2017-2022.
Method
A total of 94 patients were selected, all of which had a fFN test and were admitted at 24-33 weeks of gestational age. Concentration of fFN was divided into 5 categories: ≤10, 11-49, 50-199, 200-499 and ≥500ng/mL. A concentration of ≥50ng/mL was classified as a positive test and used as an international cutoff value.
Results
A total of 31 women had a fFN value of ≤10ng/mL; of these, 23 (74.19%) delivered term birth (TB) (≥37 weeks of gestational age), with a mean of 10 and a range of 4-14 delivery weeks following fFN testing (m:10, r:4-14), whilst 8 (25.8%) delivered a preterm birth (
Conclusion
Our preliminary data showed that the quantitative value of fFN alone is insufficient to determine PTB. Other factors should be considered such as cervical length, history of PTB, uterine surgeries, PPROM, and more. It is important to consider the etiology of PTB and apply fFN in cases where the test will benefit. The low PPV and NPV could be attributed to small sample size, therefore a larger study is needed to confirm the findings.

Maternal and Neonatal Outcomes Post Bariatric Surgery: A Population-Based Study
Objectives
This study had two primary objectives. First, to evaluate the incidence, risk factors, and maternal and neonatal outcomes among pregnant women post-BS (the exposed group). Second, to evaluate these outcomes among pregnant women without a history of BS, these include women who are obese, overweight, and with normal weight (non-exposed groups).
Design
This population-based study was conducted using 12-month retrospective registry data from the PEARL-Peristat Study at the Women's Wellness and Research Center (WWRC) in Qatar.
Methods: We examined 6,212 parturient women and their offspring. Participants were classified into exposed (post-BS) (N=315) and non-exposed (N=5897). Statistical analysis was conducted using SPSS 28 software. We analyzed the risk factors and outcomes using univariate and multivariable regression. Results were reported as odds ratios (cOR) and adjusted aOR with 95% confidence intervals (CI), while incidences were reported as percentages. P value was regarded as significant at
Results
Qatari, advanced maternal age, Parity >1, diabetes, and hypertension were found to be significant risk factors for women with post-BS.
In addition, women in the post-BS group were found to be significantly more likely to have a cesarean delivery (37.5% vs. 24%, aOR=1.59, CI 1.18-2.14), preterm babies (10% vs. 7%, aOR=1.66, CI 1.06-2.59), and stillbirth (1.6% vs. 0.4%, aOR=4.53, CI 1.33-15.50) compared to the normal weight women group. Moreover, post-BS women had a higher risk of low-birth-weight neonates than obese (15% vs. 8%, aOR= 1.77, CI 1.153-2.73), overweight (15% vs. 7%, aOR=1.63, CI:1.09-2.43), and normal weight (15% vs. 8%, aOR=1.838, CI 1.23-2.75) women. Finally, women in the post-BS group were more likely to have low-birth weight neonates (
In contrast, post-BS had a lower risk of gestational diabetes than obese (19% vs. 40%, aOR=0.39, CI: 0.29-0.54) overweight (19% vs. 32%, aOR= 0.57, CI 0.42-0.79) women. Similarly, compared to the overweight group, post-BS had a lower incidence and risk of assisted birth (4% vs. 9%, aOR=0.46, CI 0.21-0.99). On the other hand, obesity significantly increased the risk of gestational diabetes, cesarean deliveries, and labor induction in comparison to the other groups.
Conclusion
Pregnancies with post-BS should be considered a high-risk group for some outcomes and should be monitored closely. These findings may guide the future clinical decisions of antenatal and postnatal follow-up for post-BS women.
