RESUMO
Background: The novel coronavirus disease 2019 (COVID-19) was more devastating in people with comorbidities such as advanced age and immunodeficiency. Another group affected by COVID-19 was pregnant women. Immunological changes during pregnancy and conditions such as gestational diabetes and pre-eclampsia that occur during pregnancy also have effects on the fetus. The aim of this study was to analyze the effects of PCR-proven COVID-19 infection during pregnancy on fetus and newborn. Methods: Between December 2019 and October 2021, data from pregnant women with COVID-19 symptoms or a history of contact with people with COVID-19, infected with PCR-proven COVID-19 virus, were analyzed retrospectively. Clinical and laboratory data of pregnant women were analyzed. Death data associated with COVID-19 were evaluated. Clinical and laboratory findings of newborns related to COVID-19 and mortality data related to COVID-19 were recorded. The study received approval from the Gazi Yasargil Training and Research Hospital ethics committee (09.07.2021/853). Results: We evaluated 327 pregnant women who were followed up in our hospital and whose deliveries ended in live birth, stillbirth, miscarriage, or curettage. One hundred eighty-five (56.6%) of the pregnant women had at least one COVID-19-related symptom. We evaluated the data of 306 live births, 21 intrauterine fetal deaths, and 13 postnatal deaths. Among the postnatal deaths, five infants succumbed directly due to COVID-19 infection. A total of 23 live-born babies (7.5%) were classified as small for gestational age (SGA), while 80 babies (26.1%) were born before 37 weeks of gestation, and 32 babies (10.4%) were born before 32 weeks. Cord blood gas analysis revealed that 19 infants (6.3%) had pH < 7 and base excess (BE) < -12. The rate of perinatal asphyxia was significantly higher in babies born to mothers who did not survive (p = 0.027). A considerable number of infants, 119 (40.3%), were admitted to the neonatal intensive care unit (NICU). Among the seven infants with positive PCR results admitted to the NICU, five (4.2%) did not survive. Conclusion: While COVID-19 infection in pregnancy seriously affects mortality and morbidity in pregnant women, it also causes mortality and morbidity on the fetus.

Background: This study is aimed at evaluating the conservative surgical treatment of patients with placenta accreta spectrum (PAS) disorder and at presenting the experience of a single surgeon. Materials and Methods: This retrospective study included 245 patients with placenta previa accompanied by PAS disorders operated at a university hospital between June 2013 and December 2023. The diagnosis of PAS was made by a single perinatologist using a combination of transvaginal and transabdominal ultrasonography. All patients were operated with conservative surgical technique by the same surgeon. The demographic and clinical characteristics of the patients, the anesthesia and incision types used, and the details of the surgical technique were evaluated. Results: Of the patients, 165 were operated on at the scheduled time, 80 were operated on under emergency conditions, and 232 (94.69%) of them were operated on under spinal anesthesia. All patients were operated on with a Pfannenstiel incision followed by a transverse incision to the upper border of the placenta to enter into the uterus. An average of 0.52 units of red blood cells per patient was transfused to all patients. Spontaneous intra-abdominal bleeding developed in five patients, and surgical complications occurred in eight patients. No cesarean hysterectomy was performed, and no maternal mortality was detected in any of the cases. The mean time duration of surgery was 54.44 ± 11.37 (30-90) min, and the mean length of hospital stay was 1.71 ± 1.30 (1-9) days. Conclusions: We recommend this procedure as a novel technique and a robust and safe alternative to peripartum hysterectomy and other conservative surgical management procedures for cases with complete PP accompanied with PAS. This technique preserves the uterus as well as reduces blood loss, and transfusion requirement, and thus maternal morbidity and mortality in PAS cases.

BACKGROUND: This investigation aimed to analyse the efficacy of abdominal subcutaneous fat thickness (ASFT) value >18.1 mm combined with a 50-g glucose challenge test (GCT) between 24-28 weeks of gestation in predicting gestational diabetes mellitus (GDM) cases. METHODS: This cross-sectional study was carried out from February 2021 to December 2022. All pregnant women received a 50-g GCT at 24-28 weeks of pregnancy for the GDM screening. Pregnant women with a blood glucose value between 140-190 mg/dl experienced 100 g OGTT. Even if 50-g GCT was normal, 100-g OGTT was offered to patients with an ASFT value above 18.1 mm. RESULTS: Among the 728 pregnant women we enrolled, 154 (21.2%) cases were screened as positive. The number of patients who first screened positive and determined to be GDM after the 100-g oral glucose tolerance test (OGTT) was 43 (5.9%). A total of 67 cases (9.2%) had an ASFT measurement above 18.1 mm. Two cases with a negative 50-g GCT and ASFT <18.1 mm were diagnosed as GDM in the later weeks of pregnancy. A 50-g GCT combined with ASFT measurement above 18.1 mm predicted GDM with a sensitivity of 87.9%, a specificity of 88.7%, a positive predictive value (PPV) of 36.0%, and a negative PV (NPV) of 99.7%. CONCLUSIONS: A 50-g GCT combined with ASFT measurement that can be easily and accurately obtained during routine antenatal care in the second trimester might be a beneficial indicator for predicting GDM cases.
Screening and diagnosing pregnant women at greater risk of developing gestational diabetes mellitus are crucial to enhancing short- and long-term outcomes of the mother and foetus. An accurate diagnosis could provide proper treatment, which could be dietary or pharmacological, manage the disease, and improve pregnancy outcomes. In the current study, we revealed that gestational diabetes was predicted with high sensitivity and specificity in pregnant women with a 50-gram glucose challenge test and abdominal subcutaneous fat thickness measurement above 18.1 millimetres. Therefore, abdominal subcutaneous fat thickness measurement is anticipated to be extensively used as an indicative variable for predicting gestational diabetes mellitus cases during the second trimester of pregnancy.

PURPOSE: This study aimed to determine fatty acid binding protein-4 (FABP-4) concentrations in maternal serum of fetal growth restriction (FGR) pregnancies and controls of normal pregnancies. Furthermore, we hypothesized that the alterations in FABP-4 levels might correlate with FGR severity. METHODS: We performed this prospective case-control study with 83 pregnant women. The study groups included 26 FGR pregnancies without abnormal fetal Doppler flow patterns and 25 pregnancies complicated with FGR accompanied by abnormal fetal Doppler flow patterns. RESULTS: The median serum FABP-4 concentrations were significantly higher in the FGR cases with abnormal Doppler flow pattern group (2.09 ng/mL) than in the FGR cases without abnormal Doppler flow pattern group (1.62 ng/mL) and the control group (1.20 ng/mL, p < 0.001). A significant negative correlation was observed between maternal serum FABP-4 levels and time to birth from blood sample collection (r = -0.356 and p = 0.001), gestational week at birth (r = -0.386 and p < 0.001), and birth weight (r = -0.394 and p < 0.001). A 1.35 ng/mL cut-off value of serum FABP-4 level could be used to discriminate FGR cases with a 78.4% sensitivity and 60.6% specificity. The optimal cut-off value of FABP-4 levels as an indicator for the diagnosis of FGR with abnormal Doppler flow pattern was estimated to be 1.76 ng/mL, which yielded a sensitivity of 84.0% and a specificity of 75.8%. CONCLUSION: FABP-4 is a crucial biomarker in the diagnosis and determining the severity of pregnancies with restricted fetal growth. We consider that FABP-4 is a powerful, reliable, and unique biomarker to diagnose FGR pregnancies.

This study aims to examine the clinical characteristics and mortality-related factors of obstetric patients, who were taken to the intensive care unit due to Coronavirus Disease 2019 (COVID-19). This study included 31 patients in the peripartum period with COVID-19 pneumonia, followed up in the intensive care unit (ICU) from March 2020 to December 2020. Symptoms, laboratory values, intensive care unit duration of stay, complications, the requirement of non-invasive and invasive mechanical ventilation, and mortality were recorded. The mean age was 30.7 ± 6.2 years and the mean gestational age was 31.1 ± 6.4 weeks. Among the patients, 25.8% had a fever, 87.1% had a cough, 96.8% had dyspnoea and 77.4% had tachypnoea. Seventeen patients (54.8%) had mild, 6 (19.4%) had moderate and 8 (25.8%) had severe pulmonary involvement on computed tomography. Sixteen (51.6%) patients required high-frequency oscillatory ventilation, 6 (19.3%) patients required continuous positive airway pressure, and 5 (16.1%) patients required invasive mechanical ventilation. Sepsis complicated by septic shock and multiorgan failure occurred in 4 patients and all of them died. The ICU duration of stay was 4.9 ± 4.3 days. We have found that older maternal age, obesity, high LDH, AST, ALT, ferritin, leukocyte, CRP, and procalcitonin values, and severe lung involvement were mortality-related factors.Impact statementWhat is already known on this subject? Pregnant women are in the high-risk group for Covid-19 disease and its complications. Although most pregnant women are asymptomatic, severe infection-related hypoxia can cause serious foetal and maternal problems.What do the results of this study add? When we examined the literature, we found that the number of studies on pregnant women with severe Covid-19 infection was limited. For this reason, with our study results, we aim to contribute to the literature by determining the biochemical parameters and patient-related factors associated with severe infection and mortality in pregnant patients with severe Covid-19 infection.What are the implications of these findings for clinical practice and/or further research? With our study results, predisposing factors for the development of severe Covid-19 infection in the pregnant patient population and biochemical parameters that are early indicators of severe infection were determined. In this way, pregnant women in the high-risk group can be followed closely and the necessary treatments can be started quickly so disease-related complications and mortality can be reduced.

OBJECTIVE: To evaluate the clinicopathological characteristics of mismatch repair (MMR) deficiency and its clinical outcomes by performing immunohistochemistry (IHC) for MMR genes in the serous ovarian cancer (SOC) tumour sections. STUDY DESIGN: A retrospective case-control study. Place and Duration of the Study: Gynecology Department of Kanuni Sultan Süleyman Training and Research Hospital, and Department of Medical Oncology of Medipol University, between March 2001 and January 2020. METHODOLOGY: IHC was carried out for MLH1, MSH2, MSH6, and PMS2 on full-section slides from 127 SOCs to evaluate the MMR status. MMR-negative and MMR-low groups together were defined as MMR deficient and called microsatellite instability-high (MSI-H). The MSI status and expression of programmed cell death-1 (PD-1) were compared in SOCs with different MMR statuses. RESULTS: A significantly higher frequency of MMR-deficient SOCs was diagnosed at early stages compared with the patients in the MSS group (38.6% and 20.6%, respectively, p=0.022). The frequency of cases with PD-1 expression was significantly higher in the MSI-H group (76.2%) than in the MSS counterparts (58.8%, p=0.028). Patients in the MSI-H group had significantly longer DFS (25.6 months) and OS (not reached) than those in the MSS group (16 months and 48.9 months, p=0.039 and p=0.026, respectively). CONCLUSION: MSI-H SOCs were diagnosed at an earlier stage as compared to MMR proficient cases. The presence of PD-1 expression was significantly higher in cases presenting MMR deficiency compared with MMR-proficient cases. MSI status was significantly associated with DFS and OS. KEY WORDS: Serous ovarian cancer, Microsatellite instability, Mismatch repair deficiency.

OBJECTIVE: This study aimed to evaluate the effect of an increase in nuchal translucency (NT) thickness on the myocardial performance index (MPI) in fetuses without cardiac anomaly in the first trimester and to determine whether a difference in MPI between those with and without trisomy 21 in these fetuses could be determined. METHODS: The study group consisted of 53 pregnancies complicated with increased NT thickness without any associated structural anomalies. Forty-six gestational age-matched pregnant women whose fetuses had normal NT thickness were enrolled as the control group. RESULTS: In the increased NT thickness group, the mean isovolumetric relaxation time (IRT) value (0.050 ± 0.011 s) was significantly higher and the mean ejection time (ET) value (0.149 ± 0.010 s) was significantly lower than those values in the normal NT thickness group (0.045 ± 0.005 and 0.155 ± 0.009 s, p = 0.023 and p = 0.009, respectively). We found a significantly higher mean left MPI value in the increased NT thickness group (0.574 ± 0.153) versus the normal NT thickness group (0.487 ± 0.107, p < 0.001). Within the increased NT thickness group, the mean left MPI value was similar in the fetuses with normal karyotype and those with trisomy 21 (p = 0.419). CONCLUSION: We demonstrated a significantly greater mean MPI value in the increased NT thickness group than in the normal NT thickness group. Within the increased NT thickness group, no differences in the left MPI value in the fetuses with normal karyotype and the fetuses with trisomy 21 were found.

Objective: This study aimed to examine the effects of infection with the Delta variant of coronavirus disease-2019 (COVID-19) on the clinical course, laboratory parameters, and neonatal outcome in pregnant women. Material and Methods: A total of 96 pregnant women who tested positive for the Delta variant of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) causing COVID-19 were retrospectively examined. The pregnant women were divided into three groups: Asymptomatic; non-severe; and severe. Age, obstetric history, symptoms and findings, blood tests, medication and vaccination history, clinical course, and perinatal outcome of pregnant women were analyzed. Results: Pregnant women who tested positive for the Delta variant of SARS-CoV-2 had an intensive care unit (ICU) admission rate of 9.4% and a mortality rate of 5.2%. Pregnant women in the severe disease group had significantly higher rates of preterm birth and cesarean section compared with the non-severe and asymptomatic group. Pregnant women in the severe group had high C-reactive protein (CRP) levels at the time of admission. White blood cell count (WBC) and procalcitonin levels were increased in clinical follow-up in women in the severe group. Conclusion: The Delta variant of SARS-CoV-2 was found to increase mortality rates in pregnant women compared to pre-Delta variants of COVID-19. In pregnant women infected with the Delta variant, advanced gestational age at diagnosis, high CRP, WBC, and procalcitonin levels were significantly correlated with poor prognosis. Pregnant women infected with the Delta variant and with severe COVID-19 had an increased risk for preterm delivery and cesarean section. Although newborns of women with severe disease were found to have significantly higher rates of ICU admission, there was no significant difference in neonatal mortality rates. We recommend close monitoring of CRP, WBC, and procalcitonin levels, in addition to symptoms, in pregnant women infected with the Delta variant of SARS-CoV-2 and diagnosed in the third trimester.
RESUMO
OBJECTIVE: This study sought to compare the efficacy and outcomes of fetal intracardiac intraventricular and interventricular septal potassium chloride (KCl) injections during the induced fetal demise process in a cohort of pregnant women with severe fetal abnormality who opted for late termination of pregnancy (TOP). MATERIALS AND METHODS: This study consisted of 158 pregnant women who requested late TOP for severe fetal abnormality between 22 and 36 weeks of pregnancy. Participants were randomly assigned with the simple randomization procedure to one of two feticide procedure groups: the intraventricular KCl injection group and the interventricular septal KCl administration group. We studied the clinical outcomes of both the feticide procedures. RESULTS: The median total dose of strong KCl was significantly lower in the interventricular septal KCl administration group (3 mL) than in the intraventricular KCl injection group (5 mL, p < 0.001). The median time to reach asystole and the median total duration of the procedure was significantly shorter in the interventricular septal KCl administration group (42 s and 85 s, respectively) than in the intraventricular KCl injection group (115 s and 150 s, respectively, p < 0.001). We detected a statistically significant correlation between the gestational week at feticide and the total dose of KCl (r = 0.705, p < 0.001), time to reach asystole (r = 0.653, p < 0.001), and total duration of the procedure (r = 0.683, p < 0.001). CONCLUSION: KCl administered directly into the interventricular septum induces immediate and permanent fetal cardiac asystole with a 100% of success rate without comprising maternal safety. We did not observe any maternal complications related to the procedure in our cases. Since the consequences of failed feticide procedure are challenging for both parents and healthcare providers, and providers are also concerned about potential legal implications regarding an unintended live birth, it is crucial to guide a strict protocol to confirm permanent fetal cardiac asystole.

OBJECTIVE: To examine maternal serum Cripto-1 levels in placenta accreta spectrum (PAS) pregnancies and compare them with placenta previa (PP) cases and healthy pregnancies. STUDY DESIGN: A prospective case-control study. PLACE AND DURATION OF STUDY: Kanuni Sultan Suleyman Training and Research Hospital, Istanbul, Turkey, from April to September 2021. METHODOLOGY: Sixty singleton pregnant patients with PP complicated with PAS were enrolled, 45 singleton pregnant women with a diagnosis of PP without PAS, and 48 healthy uncomplicated gestational age-matched singleton pregnant women. Cripto-1 levels were determined and evaluated. RESULTS: The median maternal serum concentrations of Cripto-1 were greater in pregnant women with PAS (3.11 ng/mL) than in the PP (2.52 ng/mL) and the control groups (2.01 ng/mL, p<0.001). Based on the Youden index, a 2.557 ng/mL cut-off value of maternal serum Cripto-1 level had a 76.7% sensitivity and 72.1% specificity to diagnose pregnancies complicated with PAS. A negative and statistically significant linear relationship was found between maternal serum Cripto-1 concentration and the gestational week at birth (r= -0.325, p<0.001). A positive and statistically significant linear relationship was found between maternal serum concentrations of Cripto-1 and maternal length of hospital stay after birth (r= 0.320, p<0.001). CONCLUSION: Serum Cripto-1 levels were significantly increased levels in pregnant women suffering from PAS than in pregnant women with PP and uncomplicated healthy pregnancies. Higher expression of Cripto-1 might be a crucial factor in the pathogenesis of PAS. KEY WORDS: Abnormal placental implantation, placenta accreta spectrum, Cripto-1, Placenta previa.

PURPOSE: This study aimed to examine autotaxin (ATX) concentrations in the serum of pregnant women complicated with intrahepatic cholestasis of pregnancy (ICP) and compare them with individuals with uncomplicated healthy pregnancies. METHODS: This prospective case-control study took place with 83 pregnant women. The study group included 43 pregnant women presenting with a singleton pregnancy diagnosed with ICP in their third trimester of pregnancy. The diagnostic power of the ATX variable was examined by receiver operating characteristic analysis, and the cut-off value calculated according to the Youden index was summarized with the related sensitivity and specificity points. RESULTS: The mean serum concentration of maternal ATX was significantly higher in the ICP cases (8.91 ± 2.69 pg/mL) compared to the pregnant women in the control group (3.59 ± 1.39 ng/mL, p < 0.001). According to the Youden index, a 5.80 ng/mL cut-off value of serum ATX concentrations can be used to diagnose ICP with 97.7% sensitivity and 97.5% specificity. A significant highly positive correlation was found between maternal serum ATX levels and maternal serum total bile acid levels (r = 0.633 and p < 0.001) and itch intensity, which was objectified by the visual analog scale score (r = 0.951 and p < 0.001). CONCLUSION: Maternal serum ATX levels were significantly increased in ICP patients as compared with healthy pregnant women. Also, serum ATX activity was highly correlated with the itch intensity. We consider that ATX might represent a robust, accurate, and reliable circulating biomarker to diagnose ICP.

Objective: The current study assesses programmed death-1 (PD-1) receptor expression and CD3, CD4, and CD8 tumor-infiltrating lymphocytes (TILs) in high-grade serous ovarian cancer (HGSOC) and associates our results with neoadjuvant chemotherapy history and disease prognosis. Materials and Methods: We included cases diagnosed with primary HGSOC with biopsy or surgical resection materials in this study. The immunoreactivity of CD3, CD4, CD8, and PD1 was assessed immunohistochemically in tumor tissue. We analyzed TILs in two predetermined groups of high and low TIL. The relationships between clinical characteristics, PD-1, and TIL were assessed. by the χ(2) test or Fisher's Exact test. We used Kaplan-Meier survival analysis and Cox proportional hazards regression model to the connection between survival and the amounts of TIL, and PD1. Results: Univariate analysis demonstrated that optimal debulking (p<0.001), early International Federation of Gynecology and Obstetrics stage (p=0.046), and higher scores of stromal CD8+ TIL expression (p=0.028) in tumor cells were all substantially correlated with longer disease-free survival (DFS), whereas the remaining variables analyzed, including PD-1 positivity, stromal CD3+, and CD4+ TILs, and intraepithelial CD3+, CD4+, and CD8+ TILs, were not correlated with DFS. Also, univariate analysis revealed that optimal debulking (p=0.010), and higher scores of stromal CD8+ TIL expression (p=0.021) in tumor cells were all substantially correlated with longer overall survival (OS). Conclusion: Higher scores of stromal CD8+ TILs are substantially correlated with DFS and OS in univariate analyses, whereas scores of stromal CD3+ and CD4+ TILs, and intraepithelial CD3+, CD4+, and CD8+ TILs are not correlated with DFS and OS in both univariate and multivariate analyses. Also, we found a significant association between PD-1 positivity and the scores of stromal CD3+ TILs and intraepithelial CD8+ TILs. However, no remarkable relationship was revealed between PD-1 positivity and the survival of HGSOC cases.
RESUMO
OBJECTIVE: To examine the performance of first-trimester visceral (pre-peritoneal), subcutaneous, and total adipose tissue thickness (ATT) to predict the patients with subsequently developing gestational Diabetes mellitus (GDM). STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Obstetrics and Gynecology, Diyarbakir Gazi Yasargil Training and Research Hospital from January 2021 to July 2021. METHODOLOGY: A total of 100 pregnant women underwent sonographic measurement of subcutaneous and visceral ATT at 11-14 weeks' gestation. A 75-g oral glucose tolerance test (OGTT) was conducted between 24-28 weeks of pregnancy for the diagnosis of GDM. RESULTS: The mean visceral, subcutaneous, and total ATT were significantly higher in the GDM group (24.75 ± 10.34 mm, 26.33 ± 5.33 mm, 51.08 ± 14.4 mm) than in the group without a GDM diagnosis (16.68 ± 6.73 mm, 17.68 ± 4.86 mm, 34.25 ± 11.04, respectively, p<0.001). A pre-gestational BMI >30 kg/m2 (Odds ratio [OR]=10.20, 95% CI=2.519-41.302, p=0.001), visceral ATT (OR=33.2, 95% CI=7.395-149.046, p<0.001), subcutaneous ATT (OR=4.543, 95% CI=1.149-17.960, p=0.031), and total ATT (OR=10.895, 95% CI=2.682-44.262, p=0.001) were the factors that were found to be significantly associated with the subsequent development of GDM after adjusting for potential confounders (maternal age, and parity). The most significant risk factor for the prediction of GDM is visceral ATT with an OR of 33.2. CONCLUSION: US measurement of maternal visceral ATT during first-trimester fetal aneuploidy screening is a reliable, reproducible, cost-effective, and safe method to identify pregnant women at high risk for GDM.

OBJECTIVE: This study aimed to analyze maternal serum ß-arrestin-1 and ß-arrestin-2 concentrations in pregnant women complicated with gestational diabetes mellitus (GDM) and compare them with the normoglycemic uncomplicated healthy control group. METHODS: A prospective case-control study was conducted, including pregnant women complicated with GDM between 15 February 2021, and 31 July 2021. We recorded serum ß-arrestin-1 and ß-arrestin-2 concentrations of the participants. Receiver operating characteristic (ROC) curves were used to describe and compare the performance of diagnostics value of variables ß-arrestin-1, and ß-arrestin-2. RESULTS: The mean ß-arrestin-1 and ß-arrestin-2 levels were found to be significantly lower in the GDM group (41.0 ± 62.8 ng/mL, and 6.3 ± 9.9 ng/mL) than in the control group (93.1 ± 155.4 ng/mL, and 12.4 ± 17.7, respectively, p < .001). When we analyze the area under the ROC curve (AUC), maternal serum ß-arrestin-1 and ß-arrestin-2 levels can be considered a statistically significant parameter for diagnosing GDM. ß-arrestin-1 had a significant negative correlation with fasting glucose (r = -0.551, p < .001), plasma insulin levels (r = -0.522, p < .001), HOMA-IR (r = -0.566, p < .001), and HbA1C (r = -0.465, p < .001). ß-arrestin-2 was significantly negatively correlated with fasting glucose (r = -0.537, p < .001), plasma insulin levels (r = -0.515, p < .001), HOMA-IR (r = -0.550, p < .001), and HbA1C (r = -0.479, p < .001). CONCLUSION: ß-arrestin 1 and ß-arrestin 2 could be utilized as biomarkers in the diagnosis of GDM. The novel therapeutic strategies targeting these ß-arrestins may be designed for the GDM treatment.

OBJECTIVES: To evaluate serum neutrophil gelatinase-associated lipocalin (NGAL) concentrations of pregnant women complicated with coronavirus disease 2019 (COVID-19) and investigate its diagnostic value for the severity of COVID-19. METHODS: Of the 46 pregnant women with COVID-19 included in the study, we further classified these women into 2 subgroups: the non-severe COVID-19 group (n=25) and the severe COVID-19 group (n=21). RESULTS: Neutrophil gelatinase-associated lipocalin plasma concentrations were significantly higher in pregnant women complicated with severe COVID-19 (90 [53.1-207.7] ng/ml) compared to those from pregnant women with non-severe COVID-19 (51.8 [39.6-70.3] ng/ml) and healthy pregnant women (44.3 [32.2-54.1] ng/ml, p<0.001). Also, at a cutoff value of 72 ng/ml, NGAL predicted severe COVID-19 with a sensitivity rate of 57% and a specificity rate of 84%. Serum NGAL level (adjusted hazard ratio [aHR]=1.020, 95% confidence interval [CI]= [1.006-1.035], p=0.007), and D-dimer level (aHR=2.371, 95% CI= [1.085-5.181], p=0.030) were the variables that were revealed to be significantly associated with the disease severity. CONCLUSION: We demonstrated that NGAL was highly associated with COVID-19 severity. We consider that NGAL might be a useful biomarker to diagnose the disease severity in patients with COVID-19.

Background: The optimal delivery timing for patients with placenta previa remains controversial in the literature. To reduce spontaneous vaginal bleeding rates, which occur increasingly with advancing gestational weeks, elective cesarean delivery is advocated between 360/7 and 376/7 weeks of gestation, but this clinical approach does not take into consideration numerous patient variables. Few papers identify the risk factors for emergency cesarean delivery in patients with placenta previa. An enhanced understanding of these variables could help with determining patients at high risk for emergency cesarean delivery and individualizing delivery date scheduling. This study sought to identify predictor variables associated with emergency cesarean delivery in pregnant patients with placenta previa in a tertiary referral hospital. We also investigated differences in maternal and perinatal outcomes between patients with placenta previa who underwent emergency vs planned cesarean delivery. Methods: This retrospective cohort study included 208 singleton pregnancy patients who had a confirmed diagnosis of placenta previa at the time of delivery and who underwent cesarean delivery in our hospital beyond 24 weeks of gestation. To define risk factors of the outcome variable (emergency vs planned cesarean delivery), univariate and multiple logistic regression analysis and adjusted odds ratios with their confidence intervals were calculated. Results: Ninety-seven patients (46.6%) required emergency cesarean delivery, and 111 patients (53.4%) underwent planned cesarean delivery. Antepartum bleeding episode (37.1% and 20.7%, P=0.013) and first antepartum bleeding episode ≤28 weeks of gestation (36.1% and 14.4%, P<0.001) were significantly higher in the emergency group than the planned group. Antepartum bleeding episode (odds ratio [OR]=1.968, 95% CI 1.001-4.200, P=0.042), first antepartum bleeding episode ≤28 weeks of gestation (OR=2.750, 95% CI 1.315-5.748, P=0.007), and preoperative hemoglobin level (OR=0.713, 95% CI 0.595-0.854, P<0.001) were the independent predictors significantly associated with emergency cesarean delivery. Conclusion: Three factors-antepartum bleeding episode during pregnancy, first antepartum bleeding episode ≤28 weeks of gestation, and lower preoperative hemoglobin level-might be useful in predicting emergency cesarean delivery in pregnancies complicated with placenta previa.
RESUMO
OBJECTIVE: This study aimed to detect aquaporin-9 (AQP9) concentrations in the serum of patients with preterm premature rupture of membranes (PPROM) and compare them with the healthy control group with intact membranes. MATERIAL AND METHODS: We conducted this prospective case-control study from March 2021 to August 2021. Of the 80 pregnant patients included in the study, we enrolled 42 singleton pregnant patients with PPROM as the study group and 43 healthy gestational age-, and body mass index (BMI)-matched healthy pregnant women with intact fetal membranes as the control group. We compared demographic and clinical characteristics, complete blood count and biochemical parameters, and serum AQP9 concentrations of the participants. We constructed an ROC curve to illustrate the sensitivity and specificity performance characteristics of AQP9 and calculated a cutoff value by using the Youden index. RESULTS: Maternal serum AQP-9 concentrations were significantly higher in patients with PPROM (804.46±195.63 pg/mL) compared to the healthy pregnant women in the control group (505.97±68.89 pg/mL, p<0.001). When we examine the area under the ROC curve (AUC), the AQP-9 value can be reflected as a statistically significant parameter for diagnosing PPROM. According to the Youden index, a 654.78 pg/mL cut-off value of AQP-9 can be utilized to diagnose PPROM with 80.5% sensitivity and 100% specificity. CONCLUSION: Maternal serum AQP9 concentrations were significantly higher in PPROM patients than healthy pregnant women with an intact membrane. We suggest that AQP9 might be an essential biomarker of the inflammatory process and energy homeostasis in PPROM.

PURPOSE: This study aimed to describe the maternal and fetal outcomes associated with expectant management following previable preterm premature rupture of membranes (PPROM) before 24 weeks of gestation. We also analyzed the risk estimates of potential confounders to clarify whether these variables are contributed to the risk of postnatal mortality among these neonates. METHODS: This retrospective cohort study included all pregnant patients who experienced previable PPROM before 24 weeks of gestation at a tertiary maternal-fetal medicine center. We used the neonatal data from birth until discharge. RESULTS: A total of 128 women were enrolled. The survival to discharge rate was 60.9%. The median latency period (80 vs. 20 days, respectively, p < 0.001) was significantly longer, the median gestational week at delivery (34 vs. 25 weeks, respectively, p < 0.001) and median birth weight (2100 vs. 710 g, p < 0.001) was significantly higher in the survivor group than the non-survivor group. Surviving neonates had significantly lower frequencies of anhydramnios at any time during the latency period than the non-survivor neonates (38.4% vs. 86.0%, respectively, p < 0.001). CONCLUSION: This study demonstrated an opposite correlation between the duration of latency period and gestational age at PPROM with earlier membrane rupture in pregnancies having a longer latency period, which additionally clarifies the higher gestational age at delivery. The antepartum factors that increased the possibility of postnatal mortality within our study included the gestational week at delivery, duration of the latency period, anhydramnios at any time during the latency period, and birth weight.
