Zonulin, a protein that regulates intestinal permeability, has attracted attention as a potential biomarker for GDM. Therefore, this study aims to investigate whether there are differences in zonulin levels between the GDM group and control groups, especially between those receiving different treatments (diet and insulin). Based on this idea, we included 90 patients with a gestational age between 24 and 28 weeks in our study. While GDM was not detected in 33 of these patients, as a result of OGTT, 57 patients were diagnosed with GDM and these patients were followed throughout their pregnancy. Gestational diabetes was diagnosed by an OGTT performed between 24 and 28 weeks of gestation according to American Diabetes Association (ADA) standards. During follow-up, GDM patients were divided into two groups according to whether they required insulin treatment. Plasma zonulin levels were determined using enzyme-linked immunosorbent assay (ELISA) techniques. The GDM group had significantly higher plasma zonulin levels than the control group (p < 0.005). According to our research, zonulin may be a non-invasive biomarker involved in the etiology of GDM. Large-scale research on this topic is still needed. [ABSTRACT FROM AUTHOR]

Objective: To evaluate second trimester fetal nasal length measurement results in healthy singleton pregnancies in Turkey. Material and Methods: We analyzed the nasal bone lengths within 19-24 weeks in 661 pregnancies in our hospital. All pregnant women with a single healthy fetus who applied to our perinatology outpatient clinic for detailed obstetric ultrasonography were included in the study. All measurements were performed by the same clinician during routine mid-trimester ultrasound scan. Only the patients who were considered healthy by the examining pediatrician were included in the study. The parents of all fetuses are of Turkish ethnicity. Pearson correlation, regression analysis and P value were calculated between gestational week and nasal bone length. Results: Mean nasal length measurement was 6,21 ± 0,08; 6,66 ± 0,05; 6,88 ±0,05; 7,13 ± 0,08; 7,77 ± 0,11 and 8,33 ± 0,25 mm from 19 to 24 week of pregnancy, respectively. A significant positive correlation was observed between gestational week and nasal bone length. Normal values of nasal bone length measuremens are identified for each gestational weeks acoording to our data and previous 5 studies. Conclusion: In this study, we presented the data of our own center and the results obtained from other studies conducted in our country show significant differences. We are of the opinion that studies conducted by different researchers in different regions remain insufficient to reflect the nomogram of Turkish ethnic origin. For this purpose, multicenter studies are needed to cover the whole society. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to investigate the relationship between Chitinase 3-Like 1 gene polymorphisms and the occurrence of preeclampsia in a selected cohort of pregnant women., Methods: A total of 75 pregnant women participated in the study, 35 of whom were diagnosed with preeclampsia, while 40 served as healthy controls. The preeclamptic group was subdivided based on severity. Real-time polymerase chain reaction was employed to analyze the serum samples for variations in Chitinase 3-Like 1 gene polymorphisms., Results: The rs880633 polymorphism was found to be significantly more frequent in the control group (80%) compared with the overall preeclamptic group (60%) (p<0.05). In the severity-based subgroups, rs880633 appeared in 57.1% of non-severe and 61.9% of severe preeclamptics. Contrarily, the heterozygous form of rs7515776 polymorphism showed a significantly higher prevalence in the preeclamptic cohort (p<0.05), without distinctions in severity subgroups., Conclusion: The study suggests that the rs880633 polymorphism may serve a protective role against the development of preeclampsia, whereas the rs7515776 polymorphism may be associated with an elevated risk. Further research is warranted to elucidate the clinical implications of these findings.
