    Are serum delta neutrophil index and other inflammatory marker levels different in hyperemesis gravidarum?
    (Wiley, 2023) Dal, Yusuf; Akkuş, Fatih; Karagün, Şebnem; Çolak, Hatun; Coşkun, Ayhan
    Hyperemesis gravidarum (HEG) is a condition characterized by nausea and vomiting, fluid electrolyte and acid-base imbalance, dehydration, weight loss, and ketonuria in early pregnancy. The relationship of HEG with inflammation has been studied in many studies. This study aimed to investigate the role of serum delta neutrophil index (DNI), a new inflammatory marker, and other inflammatory markers in demonstrating the disease’s presence and severity in HEG patients.

    Comparison of the ratio of second trimester fetal biometric measurements to fetal nasal bone length in fetuses with normal karyotype and trisomy 21
    (Wiley, 2024) Dal, Yusuf; Akkus, Fatih; Karagun, Sebnem; Coskun, Ayhan
    Aim: In this study, we compared the ratio of second trimester fetal biometric measurements to nasal bone length (NBL) in fetuses with normal karyotype and trisomy 21 to determine their diagnostic prognostic value. Materials and Methods: The study included 148 pregnant women who obtained second-trimester ultrasonographic fetal anatomy and had amniocentesis (AS) for fetal karyotyping. The fetal karyotype results divided the groups into normal and trisomy 21 fetuses. Age, obstetric history, first and/or second trimester screening test risk ratios, fetal biometric measurements, and NBL mm, median (MoM) multiples, and percentile values were recorded and compared between groups. Results: BPD/NBL ratios above 9.26 predict trisomy 21 in fetuses with 77.6% sensitivity and 86.1% specificity (p = 0.001). HC/NBL ratios above 34.50 predict trisomy 21 in fetuses with 77.8% sensitivity and 88.8% specificity (p = 0.001). FL/NBL ratios above 6.02 predict trisomy 21 in fetuses with 69.6% sensitivity and 72.2% specificity (p = 0.001). HL/NB ratios above 6.56 predict trisomy 21 in fetuses with 95.5% sensitivity and 47.2% specificity (p = 0.001). The NBL MoM value demonstrated a high diagnostic accuracy for normal-karyotype fetuses (p = 0.021). Conclusion: We found that BPD/NBL, HC/NBL, FL/NBL, and HL/NBL ratios differed between fetuses with a normal karyotype and those with trisomy 21, specifically the HC/NBL ratio, which predicted trisomy 21 with good diagnostic accuracy. In identifying normal-karyotype fetuses, the NBL MoM was highly accurate.

    The initial number of fetuses in multiple pregnancy before reduction affects perinatal outcomes
    (Wiley, 2023) Akkus, Fatih; Dogru, Sukran; Atci, Asli Altinordu; Dal, Yusuf; Arici, Elifsena Canan Alp; Acar, Ali
    Objective: In this study, we aimed to evaluate the perinatal outcomes of dichorionic diamniotic (DCDA) twin pregnancies reduced by the fetal reduction (FR) procedure and cases with continuing DCDA twin pregnancies without FR. Materials and Methods: FR performed in a university hospital in the last 10 years was evaluated. Pregnancies reduced to DCDA twin pregnancies by reduction from three or more pregnancies and pregnancies that started with DCDA twins and continued with DCDA twins were compared in terms of perinatal outcomes. In the subgroup analysis, those who were reduced from three-chorionic three-amniotic (TCTA) triplets to DCDA twins and those who were reduced to DCDA twin pregnancies from four or more were compared in terms of perinatal outcomes. Results: A total of 119 pregnant women were included in the study, 36 patients underwent FR, while 83 patients were DCDA twins who did not undergo FR. The groups were similar in terms of preterm delivery (p = 0.370). There was a higher rate of miscarriage (21.4% vs. 0.0%, p = 0.019) in the group that was reduced to DCDA twins from quadruplet and above pregnancies compared to the group that was reduced from TCTA triplets to DCDA twins. The gestational week at birth was lower in the group reduced to DCDA twins from quadruplets and above pregnancies (31.00 +/- 4.31 vs. 34.64 +/- 2.88, p = 0.019). Conclusion: The study's results show that the perinatal outcomes of multiple pregnancies with and without FR are the same As the number of reduced fetuses increases, the rates of preterm birth and miscarriage also increase.
