RESUMEN

OBJECTIVES: To investigate the fetal heart using pulsed wave Doppler, M-mode, and tissue Doppler imaging (TDI) in cases of intrahepatic cholestasis of pregnancy (ICP). METHODS: This prospective study was conducted at a single tertiary center and included 35 patients with ICP and 70 healthy pregnant women at 28-36 weeks of pregnancy. Among the patients with ICP, 26 had serum bile acid (SBA) levels less than 40 µmol/L and nine had SBA levels of 40 µmol/L or greater. Pulsed wave Doppler, M-mode, and TDI evaluations were performed on the patients to assess fetal cardiac function. RESULTS: The ICP group exhibited significantly higher myocardial performance index (MPI) and isovolumetric relaxation time (IRT), but similar isovolumetric contraction time (ICT). The tricuspid and mitral valve E, A, and E/A ratios were significantly reduced in the ICP group. The TDI parameters showed significantly reduced tricuspid and mitral valve E'/A' ratios in the ICP group compared with the control group (P < 0.001). The E/E' ratio was significantly increased in the ICP group (P < 0.001). According to the M-mode Doppler findings, tricuspid and mitral annular plane systolic excursion values were significantly decreased in the ICP group (P = 0.005 and P = 0.001, respectively). In the subgroup analysis, MPI and IRT were significantly higher in the severe ICP group. CONCLUSION: ICP might induce changes in the fetal heart during the early systolic and diastolic phases. The detection of these early changes using M-mode and TDI during the antenatal period can provide valuable insights into the condition of the fetus.

RESUMEN

PURPOSE: This study aims to investigate the fetal Evans Index and establish a nomogram for fetuses without any additional fetal anomalies detected during the prenatal period. METHODS: We conducted our research at Ankara City Hospital, including 894 patients who were admitted and evaluated between gestational weeks 16-40. These patients had no fetal anomalies detected in subsequent gestational weeks. Descriptive data, such as age, gravidity, parity, and body mass index (BMI), were recorded. Gestational week and Evans Index (mean, median, standard deviation, minimum, maximum, and percentile) were also documented. The Evans index was calculated as the ratio between the maximal width of the frontal horns and the maximal width of the inner diameter of the cranium. RESULTS: We evaluated 894 fetuses in pregnant women had no fetal anomalies detected throughout the pregnancy. The evaluation took place at different gestational weeks, and a nomogram for the Evans Index was created. CONCLUSIONS: It is relevant for clinicians and researchers to be aware of the range of fetal Evans Index values across different gestational weeks as a prognostic criterion.

RESUMEN

OBJECTIVE: To investigate the contribution of the cervical sliding sign to conventional cervical length measurement in patients at risk of preterm labor. METHODS: The study, performed as a prospective cohort study, included patients admitted to a tertiary research hospital with a diagnosis of threatened preterm labor. The participants were divided into two groups: those who gave birth before and after 37 weeks of gestation. The clinical and demographic characteristics, cervical length, presence of a short cervix (SC), and cervical sliding sign (CSS) were compared between the groups. Furthermore, correlation and regression analyses were conducted to investigate the relationship between the presence of a SC, the presence of CSS, and the coexistence of these two findings with preterm delivery, as well as the interval between the symptoms and delivery being less than four weeks. RESULTS: The study included 77 patients who delivered prematurely and 65 patients who delivered at term. The following variables were significantly lower in the preterm delivery group: cervical length, gestational age at delivery, neonatal weight, and time between the first examination and delivery (p = 0.003, <0.001, <0.001 and < 0.001, respectively). A higher percentage of women in the preterm delivery group exhibited a diagnosis of a SC, the presence of CSS, and the coexistence of both conditions (p = 0.002, 0.012 and 0.018, respectively). The results of the logistic regression analysis indicated that the odds ratios for preterm delivery were 3.3 in the presence of a SC alone, 2.67 in the presence of CSS alone, and 2.85 in the association of both findings (p = 0.003, 0.013 and 0.021 respectively). The odds ratios for delivery in less than four weeks were 3.08 in the presence of a SC alone, 3.4 in the presence of CSS alone, and 3.54 in the association of both findings (p = 0.004, 0.002 and 0.005 respectively). CONCLUSION: In singleton pregnant women presenting with threatened preterm labor, the presence of CSS is associated with an increased risk of preterm delivery and a decreased presentation-to-delivery interval. However, its contribution to conventional cervical length measurement appears to be relatively limited.

RESUMEN

OBJECTIVE: To determine the value of the Aggregate index of systemic inflammation (AISI) in predicting admission to neonatal intensive care unit (NICU) and chorioamnionitis. METHODS: The present retrospective cohort study with pregnant women who were diagnosed with preterm premature rupture of membranes (PPROM) in the Department of Perinatology, Ministry of Health Ankara City Hospital between January 1, 2021, and June 1, 2023 (n = 357). The patients were categorized into subgroups: (1) cases with (n = 27) or without (n = 330) chorioamnionitis, (2) admission (n = 182) or no admission (n = 175) to NICU; (3) gestational age at birth <28 weeks or 28 weeks or longer; and (4) gestational age at birth <34 weeks or 34 weeks or longer. AISI values were compared between the subgroups, and cut-off values for AISI were determined to predict adverse outcomes. RESULTS: AISI values were significantly higher in the admission to NICU group compared with the no admission to NICU group (707.0 vs 551.2) (P < 0.05). AISI values were also significantly higher in the chorioamnionitis group compared with those without chorioamnionitis (850.3 vs 609.4) (P < 0.05). AISI levels were significantly higher in cases delivered before 28 weeks of gestation compared with the cases delivered at 28 weeks of gestation or later (945.6 vs 604.9) (P < 0.05), and were also significantly higher in cases delivered before 34 weeks of gestation compared with the cases delivered at 34 weeks of gestation or later (715.5 vs 550.1) (P < 0.05). Optimal cut-off values of AISI were found to be 626.19 (74.1% sensitivity, 52.8% specificity), 506.09 (68.9% sensitivity and, 47.7% specificity), and 555.1 (69.8% sensitivity, 48.1% specificity) in predicting NICU admission, chorioamnionitis, and delivery before 28 weeks, respectively. CONCLUSION: The novel inflammatory marker AISI may be used in the prediction of chorioamnionitis and NICU admission in PPROM cases. SYNOPSIS: Aggregate index of systemic inflammation may be used as a novel marker in predicting high-risk for chorioamnionitis and neonatal intensive care unit admission in women with preterm premature rupture of membranes.

RESUMEN

OBJECTIVES: To examine the role of the cerebro-placental-uterine ratio (CPUR) in predicting composite adverse perinatal outcomes (CAPO) in patients with pregnancy-induced hypertension (PIH). STUDY DESIGN: This prospective, case-control study was conducted at a tertiary hospital with 110 cases of PIH, including 70 patients with preeclampsia and 40 with gestational hypertension, and 110 healthy controls. The middle cerebral artery pulsatility index (MCA-PI), umbilical artery pulsatility index (UA-PI), and uterine artery pulsatility index (UtA-PI) were measured, and the cerebro-placental ratio (CPR=MCA-PI/UA-PI) and CPUR (CPR/UtA-PI) were calculated. MAIN OUTCOME MEASURE: The role of CPUR in predicting CAPO in preeclampsia and gestational hypertension. RESULTS: The CPR and CPUR values were lower in the PIH group compared to the control group (p < 0.001). CAPO had a negative correlation with CPR and CPUR (p < 0.001). Univariate regression analysis revealed that the likelihood of CAPO was increased four times by a low CPR value and six times by a low CPUR value. In the ROC analysis, the optimal cut-off value of CPR in predicting CAPO was 1.33 with 74 % sensitivity and 66 % specificity (area under the curve [AUC] = 0.778; p < 0.001) in PIH. For CPUR, the optimal cut-off value was 1.32, at which 82 % sensitivity and 79 % specificity in predicting CAPO (AUC=0.826; p < 0.001). CONCLUSION: CPUR was determined to be successful with high sensitivity in predicting adverse perinatal outcomes in the presence of PIH. In addition, CPUR was more effective in predicting CAPO in patients with preeclampsia compared to gestational hypertension. CPUR can be used to predict adverse outcomes in patients with PIH.

RESUMEN

OBJECTIVE: To compare the levels of oxidative stress markers in the umbilical cord blood between pregnant women diagnosed with iron deficiency anemia (IDA) and low-risk controls. METHODS: The sample consisted of 131 patients, including 55 pregnant women with IDA and 76 controls with similar demographic characteristics. Participants were selected from patients delivered at ≥37 weeks. We compared the two groups in terms of the native thiol, total thiol, disulfide, and ischemia-modified albumin (IMA) levels measured in pregnant women's umbilical cord venous blood. RESULTS: The native thiol and total thiol values were statistically significantly lower in the anemia group, and the disulfide and IMA values were statistically significantly higher in the IDA group (P < 0.001). Perinatal outcomes were similar between the groups. CONCLUSION: In the present study, pregnant women with IDA had lower native and total thiol values and higher disulfide and IMA values in umbilical cord blood. Iron deficiency anemia in pregnancy may be a potential cause of increased oxidative stress.

RESUMEN

INTRODUCTION: To evaluate the role of aspartate aminotransferase to platelet ratio index (APRI) in the prediction of superimposed preeclampsia in chronic hypertensive pregnancy group in the first trimester. METHODS: The present retrospective case-control study was conducted on 258 pregnant women, including 75 patients in the isolated chronic hypertension group, 92 in the superimposed preeclampsia group, and 91 low-risk pregnant women in the control group. APRI1 was calculated from routine blood test results in the first antenatal visit, and APRI2 was calculated from prelabor routine blood test results. APRI indices and other blood count parameters were evaluated and compared between groups and with the literature. RESULTS: APRI1 was lower in the superimposed preeclampsia group than in the control and chronic hypertension groups, with p-values < 0.001. In the first trimester, platelet counts were higher in the superimposed preeclampsia group than in the hypertension and control groups. APRI2 was increased in the superimposed preeclampsia group compared to the control and chronic hypertension groups, with p-values 0.001 and 0.002, respectively. The optimal cut-off value for APRI1 was 0.036 (sensitivity 65.2 %, specificity 83.7 %), and for APRI2, it was found to be 0.057 (sensitivity 67.4 %, specificity 52.0 %) to predict superimposed preeclampsia. DISCUSSION: To the best of our knowledge, this was the first study evaluating APRI in predicting superimposed preeclampsia in the first trimester. Increased platelet counts and lower APRI were found to be valuable indices for predicting superimposed preeclampsia. Further studies are needed to determine the utility of APRI in clinical practice.

RESUMEN

OBJECTIVES: To examine the fetal thymic-thoracic ratio (TTR) in intrahepatic cholestasis of pregnancy (ICP). METHODS: This prospective case-control study was conducted in a single tertiary center. The sample consisted of 86 pregnant women at 28-37 weeks of gestation, including 43 women with ICP and 43 healthy controls. TTR was calculated for each patient using the anterior-posterior measurements of the thymus and intrathoracic mediastinal measurements. RESULTS: The median TTR value was found to be smaller in the ICP group compared to the control group (0.32 vs. 0.36, p<0.001). The ICP group had a greater rate of admission to the neonatal intensive care unit (NICU) (p<0.001). Univariate regression analysis revealed that lower TTR values increased the possibility of NICU admission six times (95 % confidence interval: 0.26-0.39, p=0.01). A statistically significant negative correlation was detected between TTR and the NICU requirement (r: -0.435, p=0.004). As a result of the receiver operating characteristic analysis, in predicting NICU admission, the optimal cut-off value of TTR was determined to be 0.31 with 78 % sensitivity and 67 % specificity (area under the curve=0.819; p<0.001). CONCLUSIONS: We determined that the fetal TTR may be affected by the inflammatory process caused by the maternal-fetal immune system and increased serum bile acid levels in fetal organs in the presence of ICP. We consider that TTR can be used to predict adverse pregnancy outcomes in patients with ICP.

RESUMEN

OBJECTIVE: To evaluate the association of the Systemic Immune-Inflammation Index (SII), Systemic Immune-Response Index (SIRI), and Neutrophil-to-Lymphocyte Ratio (NLR) with Cesarean Scar Pregnancy (CSP) METHODS: This prospective case-control study was conducted in Ankara City Hospital perinatology clinic between 2022 and 2023. The diagnosis of CSP was made by transabdominal and transvaginal ultrasound. NLR, SII, and SIRI values were compared between those diagnosed with CSP (n=23) and healthy pregnancies (n=126) at the time of first admission. RESULTS: The study group had significantly higher NLR, SII, and SIRI values compared to the controls. Optimal cut-off values were 3.79 (69 % sensitivity, 78.2 % specificity), 1180.6 (76.7 % sensitivity, 72.7 % specificity), and, 1.9 (83.3 % sensitivity, 72.7 % specificity) for NLR, SII, and SIRI, respectively. When NLR, SII and SIRI values were compared between CSP cases and pregnant women who had previous history of cesarean section but did not have CSP, significantly higher SII values were observed in the CSP group. The optimal cut-off value of SII was found to be 804.4 in predicting CSP among cases with previous history of cesarean delivery (73.9 % sensitivity, 66.2 % specificity). CONCLUSION: SII, SIRI, and NLR may be useful in predicting cesarean scar pregnancy in pregnant women.

RESUMEN

PURPOSE: To examine the cerebro-placental-uterine ratio (CPUR) in pregnant women with pregestational diabetes and determine its role in predicting adverse prenatal outcomes. METHODS: This prospective, cohort study conducted at a tertiary hospital included 65 patients with pregestational diabetes (25 with type1 diabetes, 40 with type2 diabetes) and 130 low-risk patients in the control group. The cerebroplacental (CPR) ratio and the CPUR were calculated. Composite adverse perinatal outcome (CAPO) is defined as the presence of any of the following: (1) Neonatal intensive care unit (NICU) admission, (2) Apgar at 5 min <7, and (3) umbilical cord arterial pH <7.10. The relationship of CPR and CPUR with CAPO was investigated. RESULTS: CPR and CPUR were significantly lower in the pregestational diabetes group than in the control group. The NICU admission was higher in the case group. In receiver operating characteristic analyses, the optimal cut-off value of CPUR was 1.46 (AUC = 0.72, p = 0.003, 80% sensitivity, and 69% specificity) to predict CAPO and the optimal cut-off value of CPUR was 1.50 for NICU admission (AUC = 0.70, p = 0.013, 77% sensitivity, and 66% specificity). CONCLUSION: Low CPUR values were found to be associated with adverse perinatal outcomes in women with pregestational diabetes. With the increasing number of studies, CPUR is expected to be utilized more widely in routine obstetric practice.

RESUMEN

OBJECTIVE: Evaluation of demographic characteristics and postnatal outcomes of patients with suspected fetal pelvic kidney diagnosis followed in a tertiary center. METHODS: This retrospective study was conducted in Ankara Bilkent City Hospital perinatology clinic between 2020-2023. Demographic features, prenatal ultrasound findings, and postnatal outcomes were reported. RESULTS: Pelvic kidney localization was on the left in 11(55 %) patients, on the right in 7(35 %), and bilateral in 2(10 %) patients in prenatal ultrasonography. The gender of the 12(60 %) fetuses were male and 8(40 %) of them were female. The pelvic kidney was an isolated finding in 8(40 %) fetuses, additional findings were present in the remaining 12(60 %) fetuses. Pelvic kidney was confirmed postnatally by ultrasound in all 18 fetuses. However two cases with prenatal ultrasound findings resulted in intrauterine fetal demise and the final diagnosis could not be confirmed as the parents refused autopsia. Cases were divided into 3 groups according to postnatal follow-up duration as 0-12 months (n = 7), 12-24 months (n = 7) and 24-44 months (n = 4). Atrial septal defect was the most common accompanying abnormality in the postnatal period (n = 4). Smaller kidney size (n = 7), vesicoureteral reflux (n = 3), and impaired renal function (n = 3) were the most common postnatal complications. CONCLUSION: Pelvic kidney can be diagnosed in fetal abnormality screening ultrasound and postnatal follow-up should be performed closely for the assessment of renal functions.

RESUMEN

OBJECTIVE: To evaluate System Inflammation Response Index (SIRI) and Systemic Immune Inflammation Index (SII), which are the inflammatory indices, for the prediction of gestational diabetes mellitus (GDM) in the first trimester. METHODS: This was a prospective observational study conducted in a tertiary center from April 2023 to September 2023. Ninety-four pregnant women with gestational diabetes and 107 healthy pregnant women were included. The two groups were compared according to first-trimester SIRI and SII values. A receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off levels of SII and SIRI in predicting GDM. RESULTS: Significantly higher first-trimester SII and SIRI values were present in the gestational diabetes group (P < 0.001). Optimal cut-off values in the prediction of gestational diabetes were found to be 1.58 (area under the curve [AUC] 0.71, 67% sensitivity, 65% specificity, 95% confidence interval [CI] 0.64-0.78, P < 0.001) and 875 (AUC 0.70, 66% sensitivity, 65% specificity, 95% CI 0.63-0.77, P < 0.001) for SIRI and SII, respectively. Neutrophil counts, mean platelet volume (MPW), neutrophil to lymphocyte ratio (NLR), and red cell distribution width (RDW) were significantly higher in the GDM group (P < 0.001, P = 0.02, P = 0.01, P < 0.01, respectively). CONCLUSION: Novel inflammatory indices SII and SIRI may be useful in the prediction of GDM in the first trimester, but their utility in the prediction of insulin requirement is questionable. They may be used as additional tools in routine clinical practice.

RESUMEN

The systemic inflammation response index (SIRI) and systemic immune inflammation index (SII) have recently been investigated as new prognostic markers for obstetric morbidities. However, there are few studies on their predictive role in patients with pregnancy loss. Predicting miscarriages may be useful to support and prevent selected cases.The aim of this study was to investigate the role of SIRI and SII in the prediction of pregnancy loss. A total of 800 patients were included in the retrospective case-control study at a tertiary hospital.Group 1 consisted of 200 patients who had a pregnancy loss for the first time; group 2 consisted of 200 patients with recurrent pregnancy loss; the control group consisted of 400 patients who had a healthy pregnancy. The groups were compared in terms of maternal characteristics, SIRI and SII. Receiver operating characteristic analysis was performed to determine optimal cut-off values for SIRI and SII in predicting pregnancy loss. SIRI and SII were higher in the group with recurrent pregnancy loss than in the control group (p < 0.001).SIRI was higher in the first pregnancy loss group than in the control group (p < 0.001).To predict recurrent pregnancy loss, optimal cut-off values were 1.57 (80% sensitivity, 70% specificity) and 924.12 (74% sensitivity, 57% specificity) for SIRI and SII, respectively. For first pregnancy loss prediction, the optimal cut-off value was 1.38 for SIRI, with 75% sensitivity and 60% specificity. SIRI and SII may be used as inflammatory markers to predict recurrent pregnancy loss. High SIRI values can also help to predict first pregnancy loss.

RESUMEN

PURPOSE: To evaluate the utility of a novel ultrasound index "combined utero-cervical index (CUCI)" in the prediction of preterm delivery. METHODS: The present prospective cohort study was conducted in Ankara Bilkent City Hospital Perinatology Clinic between January 1, 2023, and March 31, 2023. Pregnant women with uterine contractions between 24 and 36th gestational weeks but did not have dilatation or effacement were included. CUCI was calculated as: (utero-cervical angle)/(anterior cervical lip thickness + fundal thickness + lower uterine segment thickness + cervical length). In the presence of cervical funneling, one point was added to the final result. A ROC analysis was conducted to determine the potential of CUCI in predicting delivery <37 weeks of gestation, <34 weeks of gestation, and <4 weeks after the first admission to the hospital for uterine contractions, respectively. RESULTS: Optimal cut-off values of CUCI were found to be 1.4 (67.1% sensitivity, 67.2% specificity) for predicting delivery at <37th weeks, 1.7 (72.7% sensitivity, 65.7% specificity) for predicting delivery at <34th weeks, and 1.4 (62.5% sensitivity, 61.7% specificity) for predicting delivery at <4 weeks. CONCLUSION: CUCI may be used in the prediction of preterm delivery for pregnant women admitted to hospital with preterm uterine contractions.

RESUMEN

AIM: We aim to compare the maternal serum thiol and ischemia-modified albumin (IMA) levels between pregnant women with placenta previa and those with uncomplicated pregnancies and to determine whether changes in these levels were useful in predicting cases of abnormally invasive placenta (AIP). METHODS: Fifty-five pregnant women diagnosed with placenta previa according to the diagnostic criteria (case group) were compared to 100 women with uncomplicated pregnancies of similar demographic characteristics (control group). The patients with placenta previa were further divided into two subgroups: AIP (n = 20) and placenta previa without invasion (n = 35). The maternal serum native thiol, total thiol, disulfide, and IMA levels of the groups were evaluated. RESULTS: The native thiol, total thiol, and IMA values were significantly lower in the case group than in the control group (p < 0.001). The disulfide values were similar between the study and control groups (p = 0.488). When the AIP and placenta previa without invasion groups were compared, the levels of native thiol, total thiol, disulfide, and IMA were similar (p > 0.05). CONCLUSIONS: Maternal serum thiol and IMA levels were lower in placenta previa cases compared to the control group. However, these parameters were not useful in predicting AIP cases.

RESUMEN

OBJECTIVES: To compare the postpartum shock index (SI) values between pregnant women with hypertensive disease of pregnancy (HDP) and normotensive controls. METHODS: The present study was conducted in Ankara City Hospital Perinatology Clinic. Postpartum SI was compared between the pregnant women with HDP (n=217) and normotensive controls (n=219). A logistic regression analysis was performed to assess the independent predictors of maximum SI ≥1. Finally, a ROC analysis was performed to calculate optimal cut-off values for postpartum SI's measured at different periods in the prediction of postpartum Hb (hemoglobin) decrease ≥2 g/dL. RESULTS: Peripartum SI (p<0.001), 15th min SI (p<0.001), 30th min SI (p<0.001), 2nd h SI (p<0.001), 6th h SI (p) of the HDP group (p<0.001) and max SI (p<0.001) values were found to be significantly lower in the study group. A weak positive and statistically significant correlation was found between the maximum SI and the decrease in Hb ≥2 g/dL (r=0.209; p=0.002). Optimal cutoff values for SI were; 0.7 at peripartum 0.7 at 15 min, 0.73 at 30 min, 0.6 at 2 h, and 0.7 at 6 h, respectively. CONCLUSIONS: Clinically significant blood loss may develop at lower SI values in hypertensive pregnant women.

RESUMEN

OBJECTIVE: To evaluate both short and mid-term effects of maternal COVID-19 on cardiac functions of fetuses and children. METHODS: The present case-control study was conducted on 36 pregnant women who had COVID-19 infection in the second trimester of pregnancy and 30 pregnant women as healthy controls. Fetal, neonatal, and infant cardiac functions were compared between the groups. Assessment of fetal cardiac functions were performed in the last trimester of the pregnancy at least 6 weeks after the recovery of infection. The first postnatal echo was performed within the first 2 weeks and the follow-up (second) echo was performed in the 6-8 weeks of life. RESULTS: The demographic data were similar between groups. Interventricular septum and left ventricular posterior wall end-diastolic dimensions were significantly higher in the study group in both fetal, neonatal, and infant periods. Impaired diastolic functions of right and left ventricles were detected and myocardial performance indexes with tissue doppler imaging of both lateral walls and septum were significantly higher than controls at all periods. CONCLUSION: Maternal COVID-19 seems to have a global impact on the cardiac functions of babies in the short and mid-term periods after maternal recovery.

RESUMEN

OBJECTIVES: To investigate whether fetal cardiac function is affected by underlying heart disease in pregnant women. METHODS: A total of 100 pregnant women who were ≥34 gestational weeks were included in the study, 40 in the maternal heart disease (MHD) group diagnosed with heart disease and 60 in the control group. All cardiac diseases in pregnant women were diagnosed preconceptionally and categorized according to the New York Heart Association (NYHA) classification system. Fetal cardiac functions of study groups were evaluated by M-mode, color tissue Doppler imaging (c-TDI), and pulsed wave Doppler. RESULTS: Tricuspid annular plane systolic excursion and myocardial performance index (MPI) values were significantly higher and isovolumetric relaxation time was prolonged in the MHD group. The MPI value was found higher in MHD group with NYHA Class II compared to those with NYHA Class I. No significant change in any of the fetal tricuspid annular peak velocity values measured by c-TDI in the MHD group. There were no differences in fetal cardiac functions and perinatal outcomes between pregnant women with acquired and congenital heart diseases. Patients in NYHA Class II had lower birth weight, 1st and 5th minute APGAR scores, and higher neonatal intensive care unit admission rates. CONCLUSIONS: Underlying heart diseases in pregnant women can cause alterations in the systolic and diastolic function of the fetal heart. High fetal MPI values detected in cardiac patients may indicate that cardiac pathologies during pregnancy affect fetal cardiac globular myocardial function. Cardiac pathologies that progress with restricted physical activity may cause changes in fetal cardiac function and may be associated with adverse perinatal outcomes.

RESUMEN

PURPOSE: The aim of this study was to evaluate perinatal outcomes between the uncontrolled asthma group and the mild asthma group and to reveal the relationship between disease severity and adverse maternal-fetal outcomes in this study. METHODS: This retrospective cohort study analyzed 180 pregnant women diagnosed with asthma, hospitalized, and delivered at our center between September 1, 2019, and December 1, 2021. We compared two groups: 160 with mild asthma and 20 with uncontrolled asthma. Data encompassed maternal characteristics, obstetrical complications, medication use, emergency department admissions for exacerbations, smoking status, and neonatal outcomes. RESULTS: In the uncontrolled asthma group, hospitalization rates, use of inhaled short-acting ß-agonist (SABA), and systemic corticosteroids were significantly higher compared to the mild asthma group (p < 0.01). Maternal and fetal complications were more prevalent in the uncontrolled group, including asthma exacerbations (45% vs. 1.2%), anemia (10% vs. 4.4%), prematurity (25% vs. 9.6%), and intrauterine fetal demise (IUFD) (10% vs. 0.6%). Neonatal outcomes in the uncontrolled group showed higher rates of admission to the neonatal intensive care unit (NICU) (50% vs. 25%), respiratory distress syndrome (RDS) (30% vs. 14%), and intraventricular hemorrhage (IVH) (5% vs. 0%) compared to the mild asthma group. CONCLUSION: Uncontrolled asthma during pregnancy is associated with higher adverse maternal-fetal and neonatal outcomes compared to mild asthma.

RESUMEN

PURPOSE: To develop a new cost-effective marker named creatinine-fibrinogen ratio (CFR) for the prediction of composite adverse outcomes (CAO) in placental abruption cases. METHODS: A total of 109 placental abruption patients (30 with adverse outcomes, 79 without adverse outcomes) were enrolled in this retrospective cohort study. Patients with at least one of the features listed below were included in the abruption with CAO group: requirement of blood product transfusion (erythrocyte suspension, fresh frozen plasma, pooled thrombocyte, thrombocyte apheresis), development of acute kidney injury or disseminated intravascular coagulation, and need for intensive care unit. Laboratory parameters and CFR values at admission to the hospital were compared between the two groups. RESULTS: Higher creatinine and lower fibrinogen levels were found in the CAO group (p = 0.007 and p < 0.001 respectively). The CFR value of the CAO group was significantly higher (p < 0.001). In the ROC curve analysis performed to investigate the value of CFR in CAO prediction, the area under the curve (AUC) was calculated as 0,802 (95% CI 0.709-0.895, 77% sensitivity, 65% specificity). CONCLUSION: CFR seems to be a practical marker for the prediction of CAOs in pregnant women with ablatio placenta.
