RESUMO
OBJECTIVE: This study aimed to compare cardiac morphological and functional changes in fetuses of patients with diet-regulated gestational diabetes mellitus (GDM-A1), insulin-regulated GDM (GDM-A2), and a control group. METHOD: A prospective cohort study included pregnant women aged 18-40 years with singleton pregnancies. Fetal biometric, cardiac morphological, and functional measurements were recorded using Z-scores at 34-37 weeks of gestation. RESULTS: The study included 87 patients. Both right and left ventricular wall thicknesses were significantly different between the three groups (p < 0.001 and p < 0.001, respectively). Z-scores of the mitral valve, left and right EDD were significantly lower in GDM-A1 and GDM-A2 groups compared to the control group (p < 0.001, p < 0.001, p = 0.002, respectively). Right and left ventricular areas were decreased only in GDM-A2 group compared to the control group (p = 0.003 and p = 0.001, respectively). MPI and IVRT values were also significantly higher in the same groups (p = 0.016, p < 0.001, respectively). CONCLUSION: Gestational diabetes increased IVS and ventricular wall thicknesses in both right and left ventricles, irrespective of whether it was controlled by diet or insulin. Cardiac functional changes were observed in the GDM-A2 group.
RESUMO
Objective: The aim of this study is to clarify the role of different Doppler parameters such as umbilicocerebral ratio (UCR), cerebroplacentouterine ratio (CPUR), aortic isthmus, renal artery, and umbilical vein flow Doppler in predicting adverse neonatal outcomes in fetuses with late -onset fetal growth restriction. Materials and Methods: The study included all patients diagnosed with fetal growth restriction at 32-39 weeks' gestation between 01/02/2020 and 01/02/2022 and treated at the Department of Obstetrics and Gynecology, Inonu University School of Medicine. Results: Patients included in the study had a median gestational week at delivery of 37 (minimum 33+0-maximum 39+0), median CPR of 1.42 (minimum-maximum 0.43-3.57), and median UCR of 0.7 (minimum-maximum 0.28-2.3). Receiver operating characteristic analysis was performed to determine the performance of the measured obstetric Doppler parameters in predicting the development of adverse neonatal outcomes. Umbilical venous blood flow showed the best performance in predicting adverse neonatal outcomes [area under the curve 0.952, 95% confidence interval (CI) 0.902-0.981, p<0.001]. Multivariate logistic regression analysis showed that fetuses with abnormal CPUR had a 4.5-fold (95% CI 0.084-0.583, p=0.02) increased risk of adverse neonatal outcome, whereas fetuses with abnormal umbilical venous flow had a 1.07-fold (95% CI 0.903-0.968, p<0.001) increased risk of adverse neonatal outcome. Conclusion: The results of this study demonstrate that the use of UCR, CPUR, umbilical venous flow, and aortic isthmus PI Doppler parameters along with umbilical artery PI and CPR are effective in predicting adverse neonatal outcomes in fetuses with late -onset fetal growth restriction.
RESUMO
OBJECTIVES: We classified congenital heart defects (CHDs) according to cerebral blood flow oxygenation and aimed to evaluate the effect on the size of brain structures in these fetuses. METHODS: The study which was designed retrospectively, included 28 patients with fetal CHDs and 76 patients without fetal anomalies. RESULTS: The width and length of the cavum septum pellucidum significantly increased in the CHD group (P = .002, P = .004). The biparietal diameter and z scores were significantly lower in the single ventricle (SV) (P = .006, P = .019), and the head circumference (HC) and z scores were significantly lower in the transposition of great arteries (TGA) (P = .013, P = .038). The transverse cerebellar diameter, the cerebellar HC and the cerebellar hemisphere area values were lower in the SV (P = .005, P = .017, P = .044). CONCLUSIONS: Brain structure changes are more pronounced in groups with low cerebral oxygenation, especially in the SV and the TGA.

AIM: We aimed to show the predictive value of fetal adrenal gland volume (FAGV) measurement in the success of labor induction with oxytocin. METHODS: This is a prospective cohort study that included a total of 103 term nulliparous. Immediately after deciding to induce labor with oxytocin, the fetal right and left adrenal gland measurements were obtained. RESULTS: Induction success was achieved in 89 of 103 (86.4%) pregnant women. In comparison of the FAGV values of failed induction labor group, the total volumes of right and left fetal adrenal glands and the fetal zone volumes (FZV) were found to be statistically significantly higher in the successful labor induction group (p < 0.001). In predicting induction success, the cut-off value of fetal adrenal gland volume (cFAGV) was set as >230.2 mm3 /kg and area under curve (AUC) value of 0.872 (95% confidence interval [CI], 0.736-1.000) for right total adrenal gland (p < 0.001). The cut-off value of cFAGV was set as >236.7 mm3 /kg and AUC value of 0.891(95%CI, 0.768-1.000) (p < 0.001) for left total adrenal gland. The cut-off value of cFAGV was set as >12.6 mm3 /kg and AUC value of 0.952 (95%CI, 0.905-0.999) for right FZV(p < 0.001). The cut-off value of cFAGV was set as >7.8 mm3 /kg and AUC value of 0.884 (95%CI, 0.752-1.000) for left FZV (p < 0.001). CONCLUSIONS: Two-dimension ultrasonographic measurement is an easy-to-access and noninvasive method that can be integrated into the algorithms to predict the success of induction based on FAGV measurement.

Objective: In this study, we examined the serum hematologic and lipid parameters of pregnant women with preeclampsia and an age- and gestational-age matched normotensive control group. We also compared the ratios of hemato-lipid parameters defined as systemic inflammatory markers and determined the predictive value of these values in preeclampsia. Materials and Methods: All patients diagnosed with late-onset preeclampsia or severe preeclampsia between 34 and 40 weeks of gestation at Inonu University Faculty of Medicine between March 2019 and October 2020 were included. Results: A total of 253 pregnant women were included in the study period. When the study groups were compared in terms of hematological and blood lipid profile; while serum lymphocyte, triglyceride, and total cholesterol levels were significantly higher in the preeclampsia group than in the control group (p<0.001, p<0.001, p=0.013, respectively); high-density lipoprotein (HDL)-cholesterol levels were found to be significantly lower (p=0.017). The cut-off value for the monocyte/HDL ratio in predicting severe preeclampsia was 16.65 with 59.0% sensitivity and 85.4% specificity [the area under the receiver operating characteristic 0.756, 95% confidence interval (CI) 0.681-0.821, p<0.001]. Multivariate analysis showed that the monocyte/HDL ratio was independently associated with both preeclampsia and severe preeclampsia [odds ratio (OR): 1.094; 95% CI 1.009-1.185 and OR: 1.731; 95% CI 1.218-2.459, respectively]. Conclusion: This study demonstrated that serum triglyceride and total cholesterol levels were significantly higher and serum HDL-cholesterol levels were significantly lower in pregnant women with late-onset preeclampsia compared to normotensive pregnant women. Additionally, this study revealed that the measurement of monocyte/HDL ratio in the pregnant population could be a useful clinical tool for predicting preeclampsia.
RESUMO
OBJECTIVE: To evaluate whether certain parameters on fetal cardiac morphology and geometry measured at 20-22 weeks of gestation differ in subsequently diagnosed gestational diabetes mellitus (GDM) pregnancies and whether these changes are associated with disease severity as indicated by class A1 and A2 GDM. METHOD: It was designed as a retrospective study. All measurements were taken between 20 and 22 weeks of gestation. We compared fetal cardiac structural measurements of 200 uncomplicated pregnancies (control group) with those of 307 GDM patients (160 of the them were regulated with diet (GDM A1) and 147 of them received insulin treatment (GDM A2) during pregnancy). GDM were diagnosed between 24-28 weeks of gestation with 75 gram (g) oral glucose tolerance test. RESULTS: The interventricular septum (IVS) was thicker in both in GDM A2 and GDM A1 than control (p < .001, p < .001), and there was statistically significant difference between GDM A2 and GDM A1 (p = .012). In both left and right wall thickness in GDM A1 and GDM A2 were remarkably higher than control group (p < .001, p < .001, p < .001, p < .001). The left and right spherical indices were higher in both GDM A1 and GDM A2 groups than controls (p = .021 and p = .028). Left and right area in GDM A1 and GDM A2 groups were significantly smaller than control groups (p < .001 and p = .001). CONCLUSION: Gestational diabetes is a common obstetric morbidity, which causes fetal cardiac structural changes. Our study shows that these changes can occur during the early weeks of pregnancy.

OBJECTIVE: The study aimed to estimate the rate of genetic causes that were undetectable by Cell-free DNA (cfDNA) test in prenatally diagnosed congenital heart defect (CHD) cases based on an assumption that cfDNA would accurately detect common aneuploidies including trisomy 21/18/13/45X, and del22q11.2. METHODS: This study included prenatally diagnosed CHD cases with diagnostic genetic results. The possibility of false-positive/negative results from cfDNA testing was discarded. Thus, cfDNA results would be positive in common aneuploidies or del22q11.2 and negative in normal diagnostic genetic testing results or other genetic conditions. The rate of genetic causes that were undetectable by cfDNA test was estimated for all cases as well as for CHD subgroups. RESULTS: Of 302 cases, 98 (34.8%) had a type of genetic abnormalities, with 67 having common aneuploidies or del22q11.2 and 31 having other genetic conditions. The rate of genetic causes that were undetectable by cfDNA test in CHD cases was 13.2% among those with assumingly negative cfDNA screen results and 10.3% among the entire study population. These rates were similar between CHD subgroups (p > .05). The rate of genetic causes that were undetectable by cfDNA test was higher in the non-isolated cases than in the isolated ones among those with assumingly negative-screen results (20.5% and 9.9%, respectively, p = .025). CONCLUSION: In prenatally diagnosed CDH cases, a significant number of chromosomal abnormalities are still identified after diagnostic testing even if cfDNA screen is negative, and thus it is important to extensively counsel patients with negative cfDNA screen carrying a CHD-affected fetus.

OBJECTIVES: To compare cardiac structural and functional findings of fetuses with fetal growth restriction (FGR) and small for gestational age (SGA). METHODS: In this prospective cohort study, patients were classified into three groups using Delphi procedure according to fetal weight, umbilical, uterine artery Doppler and cerebroplacental ratio. Fetal cardiac ultrasonographic morphology and Doppler examination was performed to all pregnant women at 36 weeks of gestation. RESULTS: Seventy three patients were included in the study. There were one (6.7%) patient in the control group, 2 (13.3%) in the SGA group and 12 (80%) in the FGR group who needed neonatal intensive care unit (NICU) and NICU requirement was significantly higher in FGR fetuses (p<0.001). Left spherical index was found to be lower only among FGR fetuses (p=0.046). Left ventricular wall thickness was decreased and the right/left ventricular wall ratio was increased in FGR fetuses (p=0.006, p<0.001). Tricuspid/mitral valve ratio and mitral annular plane systolic excursion value was lower in FGR fetuses (p=0.034, p=0.024 respectively). Also, myocardial performance index was remarkably higher in FGR group (p=0.002). CONCLUSIONS: We detected cardiac morphological changes in cases of both SGA and FGR-more pronounced in the FGR cases. Findings related to morphological changes on the left side in FGR cases were considered secondary to volume increase in FGR cases as an indicator of a brain-protective effect. In the FGR group, both systolic and diastolic dysfunctions were detected in the left heart.

The coronavirus disease 2019 (COVID-19) pandemic became an important public health problem affecting all age groups. The aim of this study was to evaluate clinical and laboratory findings of newborns born to mothers with COVID-19. Thirty pregnant women with COVID-19 were admitted to Turgut Ozal University Hospital for delivery. Fourteen pregnant women had at least one symptom associated with COVID-19. Positive polymerase chain reaction (PCR) results were seen in only 3 (9.7%) of 31 newborns. A statistically significant difference was observed between PCR-positive and PCR-negative newborns in terms of any adverse pregnancy outcomes. Neonatal lymphocyte count and partial arterial oxygen pressure were significantly lower in the PCR-positive group. Results were also compared according to the interval from the maternal diagnosis time to delivery. Hemoglobin and hematocrit levels in newborns born to mothers diagnosed more than 7 days before delivery were significantly lower. Neonates born to mothers with COVID-19 had mild clinical symptoms and favorable outcomes.

OBJECTIVE: To evaluate the ability of standardized early fetal heart assessment (EFHA) that includes the 4-chamber view, outflow tract relationship (OTR), and transverse arches views (TAV) of the great arteries in excluding major congenital heart defects (CHDs) in high-risk populations. METHODS: This retrospective study included high-risk pregnancies for CHDs undergoing EFHA at 11-14 weeks of gestation. Risk factors for CHDs were diabetes mellitus, a family history of CHDs, a history of a CHD use of teratogenic medications, seizure disorder, assisted reproductive treatment-conceived pregnancy, presence of at least one of the ultrasound markers: enlarged nuchal translucency (>95th percentile), tricuspid regurgitation, and reversed a-wave in the ductus venosus, presence of an extracardiac or a suspected cardiac anomaly, a high-risk first trimester combined screen result, and multiple pregnancies. EFHA consisted of visualization of 4ChV, OTR, and TAV, with and without power Doppler ultrasound. The primary outcome was the negative predictive value of EFHA in excluding major CHDs. RESULTS: EFHA was performed on 1055 fetuses. Of these, 1024 were used for the final analysis. Of these, 94.9% (n = 923) were singleton. The most common indication for EFHA was maternal DM (n = 231, 22.6%). The sensitivity, specificity, false positive, false negative, and accuracy of EFHA were 93.2%, 99.9%, 1.4%, 0.4%, and 99.5% (P < .0001), respectively, in entire included cases. The performance of EFHA was 88%, 99.9%, 1.4%, 0.4%, and 99.5% (P < .0001) respectively when the terminated cases were excluded. CONCLUSION: Early fetal heart assessment is feasible for screening for major CHDs in high-risk populations. This approach may be expanded to the general obstetric population.

Objective: This study evaluated the Toxoplasma seroprevalence rates of pregnant women among Syrian refugees and local residents and examined the effect of large-scale migrations of communities on Toxoplasma seroprevalence. Methods: A total of 29,424 pregnant women (age range: 15-45 years) who presented to Kahramanmaras Necip Fazil City Hospital Gynecology and Obstetrics Outpatient Clinic between January 2012 and January 2021 for routine follow-up during the first trimester of pregnancy were retrospectively examined and included in the study. Anti-Toxoplasma gondii IgM and IgG values of the pregnant women were divided into two groups: Local residents and refugees. Each group was divided into three age subgroups: 5-25 years, 25-35 years, and 35-45 years. Results of the refugees and local residents were compared in general terms and based on age groups. Results: The seropositivity rate for Toxoplasma IgM was higher in refugees than in local residents (2.7% vs. 1.6%; p=<0.05). Similarly, the prevalence of IgG seropositivity was higher in the refugee group (64% vs. 41%; p=<0.05). According to age groups, this statistical difference was preserved for both Toxoplasma IgM and IgG. Conclusion: It has been found that local residents and refugees in our province were above the global average in terms of Toxoplasma seropositivity rate. Seropositivity rates in the refugees appeared to be higher than those in countries with a routine screening program. Therefore, routine Toxoplasma screening should be performed in pregnant women, especially in our region.

OBJECTIVES: To evaluate the association of intertwin differences in umbilical artery pulsatility index (DUAPI) and infant survival in twin-to-twin transfusion syndrome (TTTS). METHODS: Absolute DUAPI was calculated prior to laser surgery. Receiver-operating characteristics (ROC) curve analysis provided an intertwin DUAPI cutoff of 0.4 for the prediction of double twin survival to 30 days of life. Infant survival was compared between women with an intertwin DUAPI <0.4 and ≥0.4 in the whole cohort, in TTTS cases with Quintero stages I/II and in those with Quintero stages III/IV. Regression analyses were performed to evaluate the association of intertwin DUAPI <0.4 and infant survival adjusted for confounders. RESULTS: In total, 349 TTTS cases were included. Double twin survival to 30 days was observed in 67% (234/349) of cases. Significant differences in double twin survival was seen between intertwin DUAPI groups in the whole cohort (76.8 vs. 52.2%; p<0.001), in women with TTTS Quintero stage I or II (77.8 vs. 58.5%; p=0.015) as well as in women with TTTS Quintero stage III or IV (75 vs. 49.5%; p=0.001). Intertwin DUAPI <0.4 conferred a threefold increased chance for double twin survival. CONCLUSIONS: Small intertwin DUAPI is associated with increased double infant survival in early and advanced TTTS stages.

Background/aim: Prenatal diagnosis is vital to obtain healthy generation for risky pregnancies. There have been several approaches, some of which are routinely applied in clinics to evaluate the possible prenatal deficiencies and/or diseases. In the present study, we aimed to isolate the fetal cells from endocervical samples and try to identify possible anomalies which were proved by Amniocentesis (AS) and chorionic villus sampling (CVS) methods. Materials and methods: Endoservical specimens were collected from 100 pregnant women. Cells were separated in parallel by fluorescence-activated cell sorting (FACS) and magnetic-activated cell sorting (MACS) using human leukocyte antigen (HLA) G233 and placental alkaline phosphatase (PLAP) antibodies. CMA (comprehensive meta-analysis) were carried out and male fetuses were confirmed with Sex determining region Y (SRY) amplification. Results: The percent of HLA G233 and placental and placental alkaline phosphatase (PLAP) positive cells were 4.55% and 84.59%, respectively. The percent of cells positive for both markers was 14.75%. CMA analyses were not informative. (SRY) was amplified in 67% of the samples. Conclusion: However, the success rate of the both cell sorting and scanning of DNA anomalies by aCGH and/or RT-PCR was limited, preventing the applicability of this proposal in the clinics. Still, the success of the proposed method depends on the development of the novel fetal cell-specific antibodies and the improvements in the sorting systems.

Donnai-Barrow syndrome (DBS) is an autosomal recessive disorder characterized by typical craniofacial features, vision and hearing loss, intellectual disability, agenesis of the corpus callosum (ACC), congenital diaphragmatic hernia (CDH), and omphalocele. This condition is associated with loss-of-function mutations in the LRP2 gene. Few cases have been described in the literature. In our case, CDH and ACC were prenatally diagnosed by ultrasound, and the fetus was the product of a first-degree union. Single-nucleotide polymorphism-microarray showed large regions of homozygosity. Whole exome sequencing (WES) was performed and revealed a homozygous frameshift pathogenic variant in LRP2 (c.6978dupG). Here, we present a case of DBS, which diagnosed prenatally via WES in a fetus with CDH and ACC.

AIM: We aimed to define the normal values of second-trimester fetal prenasal thickness and nasal bone length ratio (PNT/NBL) in a low-risk Turkish population and investigate the relationship between the increased PNT and nuchal fold (NF). METHOD: We retrospectively reviewed the data of 650 cases considered to be euploid fetuses who presented to our clinic between December 2013 and September 2014 for a second-line ultrasound between 17 and 24 weeks. Their PNT, NBL, NF and biometric (BPD, HC, AC, FL and HL) measurements were recorded. RESULTS: A total of 650 cases considered to be euploid fetuses were included in this study. There was a linear increase in PNT with the gestational weeks (mean value 3.01 at weeks 17-18 and 3.76 at weeks 23-24). The PNT/NB ratio showed a slight decrease in advancing gestational weeks (mean value 0.57 at weeks 17-18 and 0.50 at weeks 23-24). The 95th percentile value of the PNT/NB ratio, independent of the gestational week, was 0.76. The values of both PNT and NF increased with advancing gestational weeks, but there was no statistically linear increase between PNT and NF (R2 : 0.115). CONCLUSION: In this study, we provided a nomogram of the PNT/NB ratio. Both NF thickness and PNT should be dealt with as two separate markers. Although the formation mechanisms are thought to be the same in both of them, a strong linear relationship does not exist between them.

Corpus callosum agenesis (CCA) is a clinical condition accompanied by various aneuploidy and genetic syndromes. We identified the development of the corpus callosum (CC) in 278 patients before 18 weeks of gestational age by visualising the pericallosal artery (PCA) in the callosal sulcus and changes in the lengths and ratios of the midbrain (MB) and falx (F), which suggested elevation of the third ventricle and thalamus due to CCA in the first trimester. We succeeded in visualising the path of the PCA in 273 patients. As expected, we observed an increase in the lengths of the MB and F throughout the pregnancies. The MB:F ratio was 0.5-0.6, and it was independent of gestational age. In all 278 patients, the MB:F ratio was <0.6 (95th percentile = 0.79). We observed the presence of the CC during anatomical screening at gestational weeks 18-24. Visualisation of the PCA path (98% sensitivity) and calculation of the MB:F ratio <95th percentile (0.79-100% sensitivity) had very high sensitivity that indirectly confirmed the presence of the CC in the first trimester of pregnancy. Impact statement What is already known on this subject: After reading the articles for detecting the absence of corpus callosum (CC) at first trimester with midbrain (MB) and falx (F) measurement by Lachmann et al. ( 2013 ) and visualising pericallosal artery (PCA) as an indirect sign of CC agenesis by Pati et al. ( 2012 ), we aimed to have a look for our records visualising PCA in callosal sulcus and measure MB-F, as well as their ratios for an indirect sign of 'presence' of CC at first trimester. What the results of this study add: In recent literature, it is not possible to find many articles suggesting the presence of CC between 11 and 13 weeks of gestation. Díaz-Guerrero et al. ( 2013 ) and Pati et al. ( 2012 ) has researched visualising PCA path. Lachmann et al. ( 2013 ) reported an article for MB and F measurements in early suspicion of CC agenesis. Our study will be the first article in visualising PCA path and measuring MB-F lengths as well as their ratios for 'presence' of CC with high sensitivity rates (98% and 100%). What are the implications of these findings for clinical practice and/or further research: This study encourages clinicians visualising PCA path and measure MB-F lengths when they will try to visualise repetitive times and see how it is an easy procedure when you get used to it.

OBJECTIVE: To evaluate the effects of a gonadotropin releasing hormone agonist (GnRHa) injection prior to embryo transfer on implantation and pregnancy rate. MATERIALS AND METHODS: We performed a retrospective analysis of patients undergoing in vitro fertilization (IVF) therapy with and without GnRHa preinstallation into the uterine cavity just before embryo transfer between January 2012 and March 2013 in a single IVF center of a university hospital. Patients were evaluated based upon implantation, pregnancy, live birth, and miscarriage rates. RESULTS: GnRHa was injected into the uterine cavity of 108 patients prior to embryo transfer which were regarded as study group. One thousand forty-seven patients who were not injected GnRHa were regarded as the control group. Pregnancy rates were 44.4% and 41.7% in the GnRHa and control groups, respectively. Live birth rates were 27.8% and 26.1%, miscarriage rates were 15.7% and 15.7%, and implantation rates were 31% and 30%, respectively and there were no difference between groups statistically (p>0.05). CONCLUSION: No statistically significant differences in implantation, pregnancy, live birth, or miscarriage rates were observed in patients treated with GnRHa prior to embryo transfer, relative to the controls. Therefore, GnRHa injection into the uterine cavity prior to embryo transfer is not recommended as a means of increasing implantation or pregnancy rates in IVF. However, prospective randomized controlled studies are needed to clarify the effect of GnRHa instillation in the uterine cavity for embryo implantation in IVF.
RESUMO
OBJECTIVE: Currently, more women are delaying childbearing until their 40s.This study compared the pregnancy and maternal features, pregnancy and foetal outcomes between multiparous and primiparous patients. We compared the same factors between assisted reproductive technology (ART) and non-ART primiparous patients because of the high proportion of ART used in the primiparous patients. METHODS: The study retrospectively examined 1680 patients, 35 years of age and older, between March 2008 and February 2015. RESULTS: Comparing the features of these two groups, there was an increased incidence of employment and the use of ART in primiparous patients, while birthweight tended to be higher in the multiparous group. There were no significant differences in pregnancy complications other than hypertension disorders, such as pre-eclampsia and HELLP syndrome, which were significantly more frequent in primiparous patients. The rates of foetal growth retardation and perinatal death were significantly higher in primiparous women. Comparison of the data between ART and non-ART primiparous patients indicated that the ART group had a higher initial body mass index and a lower smoking rate. No significant differences in pregnancy complications or foetal outcome were observed between these two groups. CONCLUSION: Primiparity is associated with increased pregnancy and foetal complications in advanced age pregnancies. However, the use of ART in this age group does not seem to be an additional risk factor.

The aim of the study was to compare ischaemia-modified albumin (IMA) levels, both original and corrected, in healthy pregnancies and pregnancies complicated with preeclampsia. Maternal and cord blood samples from study (n = 16) and control (n = 17) groups were collected at the time of delivery. IMA levels were given in absorbance units (ABSU). IMA levels, both original and corrected, were compared between study and control groups. No significant difference was found between maternal and cord blood IMA levels between the study and control groups [1.0 (0.3-3.5) vs 1.2 (0.2-1.4) ABSU, p = .053 and 1.0 (0.1-2.2) vs 0.9 (0.4-3.6) ABSU, p = .382, respectively]. The results were similar for maternal IMA levels, after correction of IMA levels [1.1 (0.3-5.1) vs 1.2 (0.2-1.6) ABSU, p = .292]. IMA is a novel marker for ischaemia, without precise conclusions about its value in preeclampsia. An absolute correction formula, considering all possible intervening factors, is required for more accurate results.
