Evaluation of Serum Selenium Level, Quality of Sleep, and Life in Pregnant Women With Restless Legs Syndrome.

Restless legs syndrome (RLS) is a multifactorial disease that patients describe as restlessness in their legs, which creates a desire to move their legs, especially in the evening and at rest. This study aims to investigate serum selenium levels in RLS and document the quality of sleep and life in pregnant women with RLS according to International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria. Thirty-eight moderate to severe RLS patients with pregnancy at 38-41 weeks of gestation were determined as the case group, and 38 women with healthy gestational age-matched pregnancies were determined as the control group. Maternal serum selenium levels were compared between the RLS case group and the group of healthy pregnant women at the time of hospitalization for delivery. The Pittsburgh Sleep Quality Index (PSQI) and The Quality of Life Scale (SF-36) were applied to the patients. The mean selenium level (µg/L) was statistically significantly lower in the RLS group (53.24 ± 10.28), compared to the healthy pregnant population (58.95 ± 11.29) (P = 0.024). The PSQI score was significantly higher in the RLS case group (P = 0.033). Especially sleep efficiency (P = 0.018) and daytime dysfunction (P = 0.032) sub-parameters were affected. The SF-36 questionnaire was examined and a significant difference was detected between the two groups in role emotional (P = 0.026), social functioning (P = 0.023), and body pain (P = 0.044) sub-parameters. Serum selenium level was significantly lower, the sleep quality of the RLS group was impaired and their quality of life was affected in pregnant women with RLS. Further studies are needed to determine whether selenium replacement in pregnant women with RLS is feasible or not.

An evaluation of the results of convalescent plasma therapy applied to pregnant women diagnosed as COVID-19- positive in a pandemic center: A prospective cohort study.

BACKGROUND: Convalescent plasma (CP) might be an additional treatment modality in COVID-19. The aim of this study was to compare CP-related clinical characteristics and perinatal outcomes in pregnant women with mild or moderate-severe COVID-19. METHODS: This prospective cohort study included 36 pregnant women (12 mild and 24 moderate-severe), who underwent CP therapy. The CP obtained from recently recovered donors was transfused to patients together with maximum supportive care and antiviral agents. The groups were then compared in respect of clinical characteristics, laboratory parameters, obstetric complications, and neonatal outcomes. RESULTS: Significant differences were determined between the groups in respect of systemic corticosteroids in COVID-19 treatment (41.7%, 87.5%, p = 0.004), oxygen (O2) support (0%, 91.7%, p < 0.001), chest imaging (41.7%, 58.3%, p = 0.02), intensive care unit admission (0%, 20.8%, p = 0.03) and length of hospitalization (5.5 versus 9.5 days, p < 0.001). The O2 saturation levels before and after administration of CP were significantly lower in the moderate-severe COVID-19 group (p < 0.05). The O2 therapy time before and after administration of CP and total O2 therapy time were significantly lower in the mild COVID-19 group (p < 0.05). Platelet, plateletcrit and lymphocyte counts were significantly higher in both the mild and moderate-severe COVID-19 groups after treatment compared to the pretreatment values (p < 0.05). DISCUSSION: Although data on the results of CP treatment in pregnant women are somewhat limited, it has been suggested that early CP treatment may be associated with improvements in laboratory and ventilatory parameters in pregnant women with mild and moderate-severe COVID-19. Nevertheless, there is a need for further, randomized controlled studies on this subject with the inclusion of greater numbers of patients.

Value of shear-wave elastography and cerebral-placental-uterine ratio in women diagnosed with preeclampsia and fetal growth restriction in prediction of adverse perinatal outcomes.

PURPOSE: The aim of this study was to measure placental stiffness with shear-wave elastography technique and to evaluate the relationship with cerebral-placental-uterine ratio (CPUR) and adverse perinatal outcomes in patient groups diagnosed with preeclampsia (PE) and fetal growth restriction (FGR) in the second and third trimesters compared to the control group. MATERIALS AND METHODS: This prospective cross-sectional study was conducted at our hospital between March 2019 and March 2020. The study groups were divided into three groups: PE, FGR, and low risk pregnancy (LRP) group. The study population had singleton pregnancies and the placental site was at the anterior wall. Both shear-wave elasticity (SWE) and shear-wave velocity (SWV) were measured in the placenta during pregnancy. CPUR was calculated for each group. RESULTS: A total of 147 patients were included in this study. The mean SWE (kilopascals) values in the PE group were significantly higher than in the FGR and controls (difference of means = 3.67, 9.45; 95% CI (1.23-6.1, 7-11.8); p < .05), respectively. The mean SWV values were significantly higher in PE and FGR groups than controls (p < .05). CPUR showed correlation with central maternal surface of placenta (p: .02, r: -0.184), central fetal surface of placenta (p < .001, r: -0.288), peripheral maternal surface of placenta (p: .002, r: -0.252), and peripheral fetal surface of placenta SWE values (p: .03, r: -0.181). NICU admission was correlated with central fetal surface of placenta SWE values (p: .002, r: 0.258). CONCLUSION: In conclusion, we demonstrated increased placental stiffness in both the PE and the FGR group. Also, this difference was found to be more prominent in preeclampsia. This technique seems useful for assessment of placental function and may strengthen the utility of Doppler parameters for predicting adverse perinatal outcomes in high-risk pregnancies.

An evaluation of maternal serum dynamic thiol-disulfide homeostasis and ischemia modified albumin changes in pregnant women with COVID-19.

Objective: It is thought that oxidative stress, free radicals, reactive oxygen species and reactive nitrogen species affect the pathophysiology of coronavirus disease-2019 (COVID-19). This study aimed to evaluate the oxidative status in pregnant patients with COVID-19 infection according to the changes seen in the levels of maternal serum thiol-disulfide and ischemia-modified albumin (IMA). Materials and Methods: A study group was formed of 40 pregnant women with confirmed COVID-19 infection (study group) and a control group of 40 healthy pregnant women with no risk factors determined. In this prospective, case-controlled study, analyses were made of the maternal serum native thiol, total thiol, disulfide, IMA, and disulfide/native thiol concentrations. Results: The maternal serum native thiol and total thiol concentrations in the study group were determined to be statistically significantly lower (p=0.007 and p=0.006, respectively), and the disulfide/native thiol ratio was higher but not to a level of statistical significance (p=0.473). There was no difference between the two groups regarding IMA levels (p=0.731). Conclusion: The thiol-disulfide balance was seen to shift in the oxidant direction in pregnancies with COVID-19, which might support the view that ischemic processes play a role in the etiopathogenesis of this novel disease.

Experience of a tertiary pandemic centre on the labour and delivery of 337 pregnant women with COVID-19: a prospective cohort study from Turkey.

The aim of the present study is to share the experience of a tertiary reference pandemic centre on the labour and delivery of pregnant women with coronavirus disease 2019 (COVID-19). This prospective cohort study was conducted on pregnant women with COVID-19 (n = 337). Patients were divided into two groups based on their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) positivity (n = 103 positive and n = 234 negative) during the delivery. Thereafter, clinical characteristics and perinatal outcomes were compared between the groups. Moreover, delivery characteristics and clinical features were compared between primary caesarean section (n = 117) and normal spontaneous vaginal delivery cases (n = 100). Labour induction was performed in 16% of cases with a failure rate of 35%. Caesarean rate was 70% and the most common indication was worsening in maternal condition. Significant, positive and moderate correlations were observed between COVID-19 severity at admission (r = 0.422, p<.001), radiologic findings consistent with COVID-19 (r = 0.400, p<.001), the necessity for oxygen support during the delivery (r = 0.406, p<.001) and postpartum worsening in maternal condition. A significant, positive weak correlation was found between caesarean delivery and postpartum worsening in maternal condition (r = 0.176, p<.001). COVID-19 seems to be associated with increased rates of obstetric complications and caesarean delivery.Impact StatementWhat is already known on this subject? Increased rates of foetal distress and caesarean section were reported in pregnant women with COVID-19. Appropriate management of labour and delivery in infected pregnant women is crucial to obtain favourable perinatal outcomes.What do the results of this study add? COVID-19 seems to be associated with increased rates of obstetric complications and caesarean delivery. PCR positive group had significantly higher primary and prelabor caesarean delivery rates. Severe/critic COVID-19 infection rate was significantly higher in the primary caesarean group. Significant, positive and moderate correlations were observed between COVID-19 severity at admission, radiologic findings consistent with COVID-19, the necessity for oxygen support during the delivery and postpartum worsening in maternal condition. A significant, positive weak correlation was found between caesarean delivery and postpartum worsening in maternal condition.What are the implications of these findings for clinical practice and/or further research? Management and delivery of pregnant women with COVID-19 should be individualised. The findings of the present study may lead to the establishment of future obstetric protocols in this special population.

The Association of Serum Electrolytes with Disease Severity and Obstetric Complications in Pregnant Women with COVID-19: a Prospective Cohort Study from a Tertiary Reference Center.

Introduction To evaluate the association of serum electrolytes with disease severity and obstetric complications in pregnant women with Coronavirus disease 2019 (COVID-19). Materials and Methods This prospective cohort study was conducted on pregnant women with confirmed COVID-19. Study population was divided into two groups: 1) Mild COVID-19 group (n = 811) and 2) Moderate/severe COVID-19 group (n = 52). Demographic features, clinical characteristics, obstetric complications, and serum electrolytes were compared between the groups. Afterward, a correlation analysis was performed to investigate the association between serum electrolyte disturbances with COVID-19 severity and obstetric complications. Results Highest serum sodium, hypernatremia, potassium replacement, hypopotassemia, hyperchloremia, initial serum magnesium, hypermagnesemia, and hypocalcemia were significantly higher in the moderate/severe COVID-19 group. The lowest serum sodium, lowest serum potassium, and initial serum calcium were significantly higher in the mild COVID-19 group (p < 0.05). Statistically significant positive weak correlations were found between hypernatremia, hypopotassemia, hyperchloremia, hypermagnesemia, hypocalcemia and COVID-19 severity (r values were 0.27, 0.20, 0.12, 0.18 and 0.12, p values were < 0.001, < 0.001, 0.02, 0.03 and 0.03, respectively). Furthermore, statistically significant positive weak correlations were found between hypopotassemia, hypochloremia, hypermagnesemia, and obstetric complications (r values were 0.10, 0.10, and 0.28, p values were 0.004, 0.03, and 0.001, respectively). A statistically significant negative weak correlation was found between hypomagnesemia and obstetric complications (r = - 0.23 and p = 0.01, respectively). Conclusion Electrolyte disturbances in pregnant women with COVID-19 seem to be associated with disease severity and obstetric complications.

Comparison of clinical features and perinatal outcomes between pre-variant and post-variant periods in pregnant women with SARS-CoV-2: analysis of 1935 cases.

PURPOSE: To compare the clinical features and perinatal outcomes of pregnant women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the pre-variant and post-variant periods. METHODS: This prospective cohort study includes pregnant women with SARS-CoV-2 who were followed-up at Ankara City Hospital between 11, March 2020 and 15, September 2021. Demographic features, clinical characteristics and pregnancy outcomes were compared between the pre-variant (n = 1416) and post-variant (n = 519) groups. RESULTS: The rates of severe and critical cases significantly increased in the post-variant group (9.7% vs 2%, p < 0.001). The rates of respiratory support (26.8% vs 7.3%, p < 0.001), ICU admission (12.9% vs 1.8%, p < 0.001) and maternal mortality (2.9% vs 0.4%, p < 0.001) were significantly higher in the post-variant group. A significant increase was observed for pregnancy complications in the post-variant group (45.6% vs 18.8%, p = 0.007). The rates of preterm delivery (26.4% vs 4.4%, p < 0.001) and NICU admission (34% vs 18.8%, p < 0.001) were significantly higher in the post-variant group. Positive, weak, statistically significant correlations were observed between the post-variant period, disease severity and maternal mortality (r = 0.19, r = 0.12 and p < 0.001). CONCLUSION: Post-variant COVID-19 period was associated with a severe course of the disease and increased rates of adverse obstetric outcomes in pregnant patients.

Evaluation of the relationship between placental stiffness measured by shear wave elastography and perinatal outcomes in women with gestational diabetes mellitus.

BACKGROUND: Recently, studies on placental elastography in high-risk pregnancies continue to increase. The shear wave technique can contribute to the management of gestational diabetes mellitus (GDM) and improve perinatal outcomes by measuring placental stiffness.Purpose: To evaluate the relationship between placental stiffness measured by shear wave elastography (SWE) and perinatal outcomes in women with GDM.Material and Methods: This prospective cross-sectional study was conducted at our hospital between March and October 2020. The participants were divided into three groups: GDM-A1 group (regulated by dietary modifications); GDM-A2 group (needed pharmacologic treatment); and low-risk pregnancy (LRP) group. Both SWE and shear wave velocity (SWV) were measured in the placenta during pregnancy. RESULTS: In total, 111 women were included in the study. The mean SWE (kPa) values for the GDM-A1, GDM-A2, and LRP groups were 10.4 (range 3.1-23.3), 13 (range 4.3-29.6), and 8.3 (range 3.2-15.1), respectively. The mean HbA1c and fasting glucose values of diabetes groups showed strongly positive correlation with mean SWE and SWV values (P < 0.001, r=0.875; P < 0.001, r=0.856; P < 0.001, r=0.791; P < 0.001, r=0.740), respectively. The SWE values of central maternal and fetal surfaces of the placenta (P=0.01, r=0.242; P < 0.001, r=0.333) showed a moderately positive correlation with admission to the neonatal intensive care unit. CONCLUSION: Placental stiffness has increased in the GDM-A2 group when compared to the GDM-A1 and LRP groups. We also observed a strong positive correlation between HbA1c, fasting glucose values, and increased elasticity values in diabetic patients with metabolic dysregulation that may have clinical value.

Serum midkine level might be a diagnostic tool for COVID19 disease in pregnancy: From the disease severity, hospitalization and disease progression respects.

BACKGROUND: New biomarkers for diagnosis and monitoring the COVID-19 disease are the most important topics to be studied recently. We aimed to investigate the association between midkine levels and disease severity in pregnant women with COVID-19. METHODS: Totally 186 pregnant women were participated in this study. 96 of them were healthy pregnant women, 90 of them were pregnant women with COVID19. Pregnant women were evaluated according to their trimesters. Serum midkine level, biochemical profile clinical and disease severity outcomes of pregnant women were obtained. RESULTS: Our results showed that pregnant women with COVID19 have significantly increased serum midkine level compared to healthy pregnant women (1.801 ± 0.977 vs 0.815 ± 0.294 ng/dL). According to the data among each trimester, it was shown that there were significant increase in serum midkine level during all pregnancy trimesters (1st trimester Control Group: 0.714 ± 0.148, COVID-19 group 1.623 ± 0.824, p < 0.0001; 2nd trimester Control Group: 0.731 ± 0.261, COVID-19 group 2.059 ± 1.146, p < 0.0001; 3rd trimester Control Group: 1.0 ± 0.35, COVID-19 group 1.723 ± 0.907, p = 0.001). Serum midkine levels were significantly different between disease severity subgroups of pregnant women with COVID19; moderate and severe/critic groups had significantly higher serum midkine level than mild group. There was also significant correlation between serum midkine level and severity status (p:0.0001, r: 0.468). The most striking results of serum midkine levels were corelation between length of hospitalization (p: 0.01, r: 0.430) and O2 saturation (p < 0.0001, r: -0.521). ROC curve analysis showed that serum midkine level might be a tool for predicting COVID-19 in pregnant women with COVID-19 (AUC: 0.912, 95% CI: [0.871, 0.952], p < 0.0001) CONCLUSION: Our data showed that there is an obvious relation between COVID19 progression and serum midkine level for the first time which might be used for monitoring the disease process.

Management of pregnant women with COVID-19: A tertiary pandemic center experience on 1416 cases.

The aim of this study is to share the comprehensive experience of a tertiary pandemic center on pregnant women with COVID-19 and to compare clinical outcomes between pregnancy trimesters. The present prospective cohort study consisted of pregnant women with COVID-19 who were followed up at Ankara City Hospital between March 11, 2020 and February 20, 2021. Clinical characteristics and perinatal outcomes were compared between the pregnancy trimesters. A total of 1416 pregnant women (1400 singletons and 16 twins) with COVID-19 were evaluated. Twenty-six (1.8%) patients were admitted to the intensive care unit (ICU) and maternal mortality was observed in six (0.4%) cases. Pregnancy complications were present in 227 (16.1%) cases and preterm labor was the most common one (n = 42, 2.9%). There were 311, 433, and 672 patients in the first, second, and third trimesters of pregnancy, respectively. Rates of mild and severe/critic COVID-19 were highest in the first and second trimesters, respectively. The hospitalization rate was highest in the third trimester. Pregnancy complications, maternal mortality, and NICU admission rates were similar between the groups. The course of the disease and obstetric outcomes may be different among pregnancy trimesters. A worse course of the disease may be observed even in pregnant women without any coexisting health problems.

Evaluation of Fetal Serum Thiol/Disulfide Homeostasis and Ischemia-Modified Albumin Levels in Fetal Distress.

Aim: We investigated the association of fetal serum thiol/disulfide homeostasis and ischemia-modified albumin (IMA) levels with fetal distress (FD). Methods: Umbilical cord blood for native thiol, total thiol, disulfide, albumin, and IMA analysis was obtained from 44 pregnant women over 34 weeks gestation undergoing cesarean section due to non-acute FD, and from 61 healthy pregnant women who underwent elective cesarean section Results: Native thiol and total thiol levels were significantly lower in the FD group (p = 0.02 and p = 0.014, respectively). Although disulfide/native thiol and disulfide/total thiol ratios were higher in the FD group, the difference was statistically insignificant (p = 0.805). The IMA levels were significantly higher in the FD group (p = 0.013). Conclusion: The thiol-disulfide homeostasis shifts toward the oxidant direction during the FD pathogenesis and the increased IMA levels may be the best indicator of an underlying non-acute ischemic condition.

Can Anakinra and corticosteroid treatment be an effective option in pregnant women with severe Covid-19?

Anakinra, which is an Interleukin-1 (IL-1) receptor antagonist with the advancing disease process, has started to be considered as an alternative treatment for Covid-19 patients with cytokine storms. We evaluated the effect of corticosteroids and IL-1 receptor blockage with anakinra on pregnant patients with Covid-19 at high risk for respiratory distress, ongoing fever, deterioration in their general condition and consequently maternal and fetal complications. Fourteen pregnant women who received anakinra (median dosage: 400 mg) and corticosteroid (methylprednisolone-median dosage: 80 mg) treatment were evaluated retrospectively. Patients were assessed according to the World Health Organization (WHO) scale. The mortality rate of the cohort was 7.1%, the median hospitalization period of the patients was 15 days and 2 patients had premature births. Covid-19 was found to have a similar spectrum of symptoms in pregnant and non-pregnant women, such as dyspnea, cough and fever. Our study was the first to analyze the combined treatment of corticosteroid and anakinra in pregnant patients with pneumonia from Covid-19 based on the WHO scoring system. Due to the obscurity in the treatment process in pregnant patients, studies are ongoing on managing Covid-19 infection in these patients. We presume that the early use of anakinra and corticosteroid treatments in patients severely infected with Covid-19 may have positive effects on disease progression and survival.

Neurosonographic assessments of corpus callosum related structures in growth-restricted fetuses.

PURPOSE: The aim of this study was to evaluate whether corpus callosum length (CCL), corpus callosum-fastigium length (CCFL) and the angle between CCL-CCFL (CCFA) were altered in growth-restricted fetuses. METHODS: This prospective case-control study was conducted in a tertiary center. A total of 80 singleton fetuses were included in the study, classified as 36 late-onset growth-restricted fetuses and 44 adequate-for-gestational-age fetuses. All biometric measurements and Doppler assessments of umbilical artery, middle cerebral artery, and ductus venosus were performed via the trans-abdominal route. CCL, CCLF, and CCFA were assessed via the trans-vaginal route. RESULTS: Late-onset growth-restricted fetuses showed significantly reduced CCL and CCFL. There was no statistically significant differences in terms of CCFA. Moderate-high correlations between CCL and biparietal diameter, head circumference, abdominal circumference, FL and gestational age were detected (r: 0.482 p: 0.000; r: 0.537 p: 0.000; r: 0.488 p: 0.000; r: 0.519 p: 0.000; and r: 0.472 p: 0.000, respectively). CONCLUSION: This study adds to the literature that CCFA has not changed despite the decrease in CCL and CCFL in late-onset fetal growth restriction that might be a result of the redistribution of cerebral blood flow. To clarify the prognostic implications of these results in terms of neural and cognitive functions in postnatal life, there is a need for larger prospective studies.

A comparison of the maternal levels of serum proprotein convertase subtilisin/kexin type 9 in pregnant women with the complication of fetal open neural tube defects.

It was aimed to evaluate the levels of maternal serum proprotein convertase subtilisin/kexin type 9 (PCSK9) in pregnant women with a fetus diagnosed with open neural tube defects (NTDs). This case-control study included 38 pregnant women carrying fetuses with open NTDs and 44 age-matched, pregnant women with no specified risk factors. Comparisons were made of the groups in respect of demographic and clinical data and PCSK9 levels. To examine the performance of PCSK9 levels in the prediction of fetal open NTDs, receiver operating characteristic (ROC) curve analysis was used. In the first and second trimesters, PCSK9 levels were determined to be lower in the NTD group than in the control group (p = 0.010 and p = 0.015, respectively). In the first trimester, the lower PCSK9 levels in the NTD group were not statistically significant (p = 0.575). In the second trimester, the ROC curve value with the best balance of sensitivity/specificity for PCSK9 was 71.9 ng/ml (84.6% sensitivity, 51.7% specificity) and in the first and second trimester combined, 74.4 ng/ml (81.6% sensitivity, 45.5% specificity) (p = 0.015, p = 0.036, respectively). PCSK9 may be involved in the etiopathogenesis of open NTDs at the critical steps of fetal neuronal differentiation. Although it has limitations, PCSK9 may be used as an additional biomarker for the screening of NTDs.

Maternal selenium status plays a crucial role on clinical outcomes of pregnant women with COVID-19 infection.

Adequate maternal selenium level is essential for immune response and healthy pregnancy. This study aimed to shed light on the selenium status of pregnant women with COVID-19 and the effects of potential deficiency in serum selenium levels. Totally 141 pregnant women, 71 of them were COVID-19 patients, in different trimesters were included in the study. Maternal serum selenium levels, demographic and clinical parameters were determined. Serum selenium levels of pregnant women in the second (p: .0003) and third (p: .001) trimesters with COVID-19 were significantly lower than in the healthy group. Maternal selenium level was found to be negatively correlated with gestational week (p < .0001, r: -.541), D-dimer (p: .0002, r: -.363) and interleukin-6 (IL-6) level (p: .02, r: -.243). In the second trimester, serum selenium level positively correlated with white blood cell (p: .002, r: .424), neutrophil (p: .006, r: .39), lymphocyte (p: .004, r: .410) count and hemoglobin (p: .02, r: .323), hematocrit (p: .008, r: .38) status. In the third trimester, it was found that maternal selenium level positively correlated with monocyte (p: .04, r: .353) and negatively correlated with C-reactive protein level (p: .03, r: -.384). Serum selenium level was gradually decreased during the pregnancy period, however, this natural decrease was enhanced together with COVID-19 infection. The reason might be increased selenium needs depended on the immune response against infection. The decrease in maternal selenium level was found to be related to IL-6 and D-dimer levels, which indicate selenium's role in disease progression.

The effect of real-time polymerase chain reaction cycle threshold values on perinatal outcomes of pregnant women with COVID-19.

OBJECTIVE: To evaluate the effect of cycle threshold (Ct) values on the pregnancy outcomes of women with coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: This prospective cohort study was conducted on pregnant women with COVID-19. A real-time polymerase chain reaction (RT-PCR) assay of a nasopharyngeal and oropharyngeal specimen was used for the diagnosis. Initial Ct values for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR tests were recorded. 22.9 was the 50th percentile Ct value of the study population. The study population was divided into two groups based on their Ct values: (1) Cases with Higher Ct values (Ct > 22.9)(n = 50) and (2) Cases with lower Ct values (Ct ≤ 22.9)(n = 55). Demographic features, clinical characteristics, disease progression, laboratory test results and pregnancy outcomes were compared between the groups. A receiver operating characteristic (ROC) curve was used to assess the performance of Ct values in predicting obstetric complications. RESULTS: Obstetric complication rate was significantly higher in cases with lower Ct values (p < .001). A significantly lower lymphocyte count together with higher ESR, procalcitonin and IL-6 values were observed in the cases with lower Ct values (p > .05). Additionally, a significantly higher NICU admission rate and longer hospital stays were present in the cases with lower Ct values (p > .05). The value in ROC curves with the best balance of sensitivity/specificity was 22.5 (85.7% sensitivity, 63.6% specificity). CONCLUSION: Lower Ct values may be associated with an increased rate of obstetric complications in pregnant women with COVID-19. Physicians should be cautious in the management of cases with Ct levels below 22.5.

Skin Color May Predict Intra-Abdominal Adhesions During Repeated Caesarean Section Deliveries.

OBJECTIVE: Caesarean rates have increased rapidly for various reasons recently. One of the important reasons among these is medicolegal problems. Our aim with this study was to preoperatively predict abdominal adhesion density by combining the scar tissue morphology formed in the post-caesarean Pfannenstiel incision line and the skin color scoring of the patients. MATERIAL AND METHODS: Patients who had undergone one caesarean section previously, completed their terms (37-39 weeks) and were under 35 years old were included in the study. Skin color scoring of the patients was performed using the Fitzpatrick skin color scale. Intra-abdominal adhesion scoring of the participant patients was performed using Nair's adhesion scoring system. RESULTS: The change in abdominal adhesion scores was evaluated based on the Fitzpatrick color scale. Adhesion scores per the Nair intra-abdominal adhesion scoring system were found to be 0.04±0.209 in the FP1 group, 0.35±0.662 in the FP2 group, 1.58±0.923 in the FP3 group, and 2.33±0.577 in the FP4 group (p<0.05). These results showed a significant increase in adhesion density with increasing skin color darkness. Based on these results, it was observed that the abdominal adhesion scores and the frequency of depressed skin scar were significantly increased with increasing Fitzpatrick scores (p<0.05). CONCLUSION: The aim of this study was to increase the prediction rates by adding the skin color scoring to the scar tissue characteristics, which have been used in previous studies. The results of this study indicate that the combination of these two parameters may be more effective in predicting intra-abdominal adhesions. Nevertheless, there is a need for studies with a much higher number of patients and multiple parameters to be able to predict intra-abdominal adhesion density preoperatively with greater accuracy.

The impact of COVID-19 infection on the cytokine profile of pregnant women: A prospective case-control study.

OBJECTIVE: To compare the levels of various cytokines between pregnant women with confirmed coronavirus disease (COVID-19) infection and pregnant women without any defined risk factor. MATERIALS AND METHODS: Pregnant women with confirmed COVID-19 infection (study group)(n = 90) were prospectively compared to a gestational age-matched control group of pregnant women without any defined risk factors (n = 90). Demographic features, clinical characteristics, laboratory parameters, interferon-gamma (IFN γ), interleukin (IL-2), IL-6, IL-10, and IL-17 levels were compared between the groups. Additionally, a correlation analysis was performed in the study group for the assessment of IFN γ, IL-2, IL-6, IL-10, and IL-17 levels with disease severity and CRP levels. RESULTS: Study group had significantly higher pregnancy complication rate, erythrocyte sedimentation rate, C-reactive protein, procalcitonin, ferritin, D-dimer, lactate dehydrogenase, IFN γ, and IL-6 values (p < 0.05). On the other hand, the control group had significantly higher hemoglobin, leukocyte, platelet, lymphocyte, IL-2, IL-10, and IL-17 values (p < 0.05). Statistically significant differences were found between the groups for IFN γ, IL-2, IL-10, and IL-17 values between the trimesters (p < 0.05). Statistically significant positive correlations were found for IFN γ and IL-6 with disease severity (r = 0.41 and p < 0.001 for IFN γ and r = 0.58 and p < 0.001 for IL-6). On the other hand, a moderate negative correlation for IL-2 and a weak negative correlation for IL-10 were present (r = -0.62 and p < 0.001 for IL-2 and r = -0.19 and p = 0.01 for IL-10). A statistically significant positive moderate correlation was found between IL-6 and CRP (r = 0.40 and p < 0.001) CONCLUSION: COVID-19 infection seems to have an impact on the cytokine profile of pregnant women varying according to pregnancy trimesters and cytokine levels seem to be correlated with disease severity.

Fetal Genetic Diagnosis by Chorionic Villus Sampling: Evaluation of the Five-Year Experience from a Single Center.

OBJECTIVE: We summarized our five-year chorionic villus sampling (CVS) experience with indications, detected chromosomal abnormalities and pregnancy outcomes. Materials and Methods: This retrospective study examined 552 patients underwent CVS for prenatal diagnosis between 2014 and 2018. Results: The most frequent patients undergoing CVS indications were abnormal aneuploidy screening results, increased nuchal translucency, and cystic hygroma/edema. Of 552 CVS, 385 were normal, 141 abnormal. Eight were contaminated with maternal cells, 4 were mosaics, in 12 the culture failed, and in 2 there was inadequate sampling. The most frequent chromosomal abnormalities were trisomy 21, trisomy 18 and 45,X. Of 246 followed pregnancies, there were 165 live-births (67,1%), 58 pregnancy terminations (23,6%), and 23 pregnancy losses (9,3%). There were 5 procedure-related losses (2%), 3 of which were chromosomally normal. Conclusion: Although significant advances have been made in noninvasive methods such as NIPT, CVS is still a reliable technique for cytogenetic diagnosis in early gestation.

The Relation Between Trace Element Status (Zinc, Copper, Magnesium) and Clinical Outcomes in COVID-19 Infection During Pregnancy.

SARS CoV-2 is a novel coronavirus which has caused many deaths in the recent pandemic. This study aimed to determine zinc, copper and magnesium status on pregnant women with COVID-19. 100 healthy (33/32/35) and 100 SARS-CoV-2 positive (34/33/33) pregnant women were included in the study according to their trimesters. Blood samples were obtained from the patients along with the initial laboratory tests for clinical outcomes upon their first admission to hospital. In the first and third trimesters serum zinc level was lower (p:0,004 and p:0,02), serum copper level was higher (p:0,006 and p:0,008), the Zn / Cu ratio decreased(p < 0.0001 and p < 0.0001) and the serum magnesium level was higher(p < 0.0001 and p < 0.0001) in the COVID-19 group.In the second trimester COVID-19 patients had lower serum zinc (p:0,05) and copper levels (p:0,0003) compared to controls. Disease severity correlated with zinc/copper ratio in COVID19 patients (p:0.018, r:-0.243). Serum zinc and Zn/Cu ratio levels had a negative relationship with acute phase markers such as IL-6, Erythrocyte Sedimentation Rate, procalcitonin and C-reactive Protein. Also, increased serum magnesium level may play a role in decreased white blood cell, neutrophil, lymphocyte cell count and increased CRP levels in the third trimester. This study indicated that trace element status changed in pregnant women with COVID-19. The effect of trace elements on pregnant women diagnosed with COVID-19 infection was investigated in comparison with healthy pregnant women for the first time. This effect will be revealed better in more comprehensive studies to be planned in the future.
