Objective: To evaluate hereditary and acquired hemostatic abnormalities associated with recurrent spontaneous early (first-trimester) abortions.
Method: A group of 56 Greek women with two or more unexplained primary spontaneous abortions, and a reference group of 148 women without a history of recurrent abortions, were screened for hypercoagulability. A randomly selected population of first-trimester pregnant women was also chosen for factor V Leiden genetic screening.
Results: A total of 21% of the women with recurrent abortions, compared with 12% of the reference group, showed increased activated protein C resistance. Fourteen per cent had positive lupus anticoagulant, compared with 11.5% of the reference group. For the rest of the parameters, there was no difference between the two groups. Of 22 women studied for factor V Leiden, one was homozygous and one was heterozygous. Results were compared using Fisher's exact test and two-tailed Student's t tests.
Conclusions: Increased activated protein C resistance appears to be an important factor in women with recurrent abortions. These data indicate the need for routine investigation of activated protein C resistance in women with recurrent abortions.

Patients with a transabdominal cerclage due to recurrent mid-trimester losses are not at higher risk of foetal growth restriction: a retrospective study.

Foetal growth restriction (FGR) is associated with neonatal morbidity, suboptimal neurodevelopmental outcomes and chronic diseases. Successful pregnancies of women with recurrent mid-trimester pregnancy losses may still be at risk of FGR and small for gestational age (SGA) outcomes. This study aimed to investigate whether patients with recurrent mid-trimester pregnancy losses who undergo transabdominal cerclage (TAC) are at an increased risk of FGR.

Objective: Abnormal levels and imbalances of T cell subsets are common in recurrent spontaneous abortion (RSA) patients, but most studies have small sample sizes, and comprehensive evaluations are lacking. Therefore, this meta-analysis aimed to comprehensively investigate T cell subsets and their ratios in RSA patients.
Methods: Four databases (PubMed, EMBASE, Web of Science, and Cochrane Library databases) were searched until 10 January 2024.

Recurrent miscarriage (RM) is a reproductive disorder affecting couples worldwide. The underlying molecular mechanisms remain elusive, even though emerging evidence has implicated endoplasmic reticulum stress (ERS). We investigated RM- and ERS-related genes to develop a diagnostic model that can enhance predictive ability.

Background: This study aimed to analyze the impact of preoperative cervical length before cervical cerclage on the extension of gestational days in patients with various diagnostic types of cervical insufficiency, including obstetric history-based diagnosis, ultrasound-based diagnosis, and physical examination-based diagnosis.
Methods: 168 patients were segregated into four categories based on cervical length: 0-0.4 cm, 0.

Recurrent pregnancy loss (RPL) represents a complication of pregnancy occurring in 1%-3% of all couples trying to conceive. About 50%-60% of RPL cases remain idiopathic, therefore therapeutic strategies seem empirical and based on unproven evidence. We investigated the efficacy of corticosteroids in women with RPL.
