This study investigates the role of Delta Neutrophil Index (DNI), an inflammation marker, in late-onset fetal growth restriction (LO-FGR) and its prediction of composite adverse neonatal outcomes. A retrospective study was conducted on 684 pregnant women (456 with normal fetal development and 228 with LO-FGR) who delivered at Health Sciences University Etlik Zubeyde Hanim Women’s Health Training and Research Hospital between January 1, 2015, and June 30, 2018. Composite adverse neonatal outcomes were defined as at least one of the following: 5th minute APGAR score < 7, respiratory distress syndrome (RDS), or neonatal intensive care unit (NICU) admission. The FGR group had significantly higher levels of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte to lymphocyte ratio (MLR), and DNI compared to controls (p < 0.05, for all). For FGR diagnosis, the DNI demonstrated the highest area under the curve (AUC = 0.677, 95% CI: 0.642–0.711) with a cut-off value of > -2.9, yielding a sensitivity of 78.41%, a specificity of 52.97%, a positive likelihood ratio (+ LR) of 1.68, and a negative likelihood ratio (-LR) of 0.37 (p < 0.001). For predicting composite adverse neonatal outcomes in the FGR group, DNI again demonstrated superior performance with an AUC of 0.635 (95% CI: 0.598–0.670), a cut-off value of > -2.2, a sensitivity of 69.90%, a specificity of 55.36%, a + LR of 1.56, and a -LR of 0.51 (p < 0.001). NLR, PLR, and MLR had AUCs below 0.55, indicating poor discriminative ability, with none reaching statistical significance. This study highlights the potential role of DNI as a promising biomarker for detecting inflammatory processes associated with LO-FGR and its complications.

Background: To evaluate cases diagnosed with fetal abdominal cyst diagnosed in prenatal period. Methods: We retrieved the cases diagnosed with fetal abdominal cyst between the years 2018 and 2020 from hospital's database. The localization, origin, dimensions, properties (simple or complex), and characteristics (solid, cystic, vascularity) were noted both in prenatal and postnatal period. We also tested the diagnostic performance of ultrasonography according to endpoint diagnosis revealed postnatally. Results: During the study period, a total of 29 cases diagnosed as fetal abdominal cyst. Of them, there were 11 (37.9%) gastrointestinal, 9 (31%) ovarian, 6 (20.6%) genitourinary, 3 (10.3%) hepatobiliary system cysts. In our study, we were able to identify 5 (45%) of 11 fetuses with postnatally confirmed gastrointestinal system cysts, 1 (33%) of 3 fetuses with hepatobiliary system cysts, 3 (50%) of 6 fetuses with urinary system cysts and 6 (66%) of 9 fetuses with ovarian cysts. Conclusion: İn this study, the most common abdominal cyst was ovarian cysts. The most difficult to diagnose cysts are those that originated from gastrointestinal system and hepatobiliary system.

Aim: To compare fetal and maternal outcomes between elective and emergency cesarean sections in patients with gestational diabetes mellitus (GDM). Material and Methods: Data from patients with GDM delivered by cesarean section between January 2015 and July 2020 were retrospectively reviewed. Patients were grouped according to whether the cesarean section was elective (n=129) or emergency (n=158). Results: The cesarean section rate was higher in patients with GDM (31.16%) than in patients without GDM. There were more patients with inadequate maternal care in the emergency cesarean section group than in the elective cesarean section group (p=0.003). One neonate in the elective group and six in the emergency C/S group died, but the rates of neonatal mortality were similar (p=0.198). Maternal morbidity (wound infection, fever, blood transfusion, and maternal intensive care) and fetal morbidity (birth asphyxia, respiratory morbidity, and neonatal intensive care) were higher in the emergency C/S group (p
