RESUMEN
RESEARCH QUESTION: Are there differences between in-vitro maturation (IVM) primed with letrozole-human chorionic gonadotrophin (HCG) and IVM primed with FSH-HCG in women with oocyte maturation abnormalities (OMAs), defined as at least two failed IVF cycles where immature oocytes were retrieved? DESIGN: This retrospective study was conducted at a private fertility clinic from January 2009 to April 2023. The final analysis included 75 women in Group 1 (IVM primed with FSH-HCG) and 52 women in Group 2 (IVM primed with letrozole-HCG). RESULTS: A significantly higher median number of oocytes was obtained in Group 1 compared with Group 2 {9 [interquartile range (IQR) 1-5] versus 5 (IQR 1-18); P < 0.001}. However, no differences in oocyte maturation stage at collection were found between the groups (P > 0.05). At the end of IVM, Group 1 had 73/666 mature oocytes and Group 2 had 106/322 mature oocytes, and the median metaphase II oocyte rate per patient was higher in Group 2 [33.3% (IQR 66.7-100.0%) versus 0.0% (IQR 0.0-22.2%); P < 0.001]. Moreover, Group 2 demonstrated a higher median fertilization rate [66.7% (IQR 50.0-100.0%) versus 50.0% (IQR 0.0-66.7%); Pâ¯=â¯0.027]. Group 2 had a higher proportion of Grade 2 embryos (58.5% versus 6.3%), and Group 1 had a higher proportion of Grade 3 embryos (93.8% vs 24.4%; P < 0.001). Notably, all pregnancies obtained in the study were in Group 2 (5 versus 0; Pâ¯=â¯0.042). CONCLUSIONS: IVM primed with letrozole-HCG in women with prior failed IVF cycles due to OMAs may result in mature oocytes, clinical pregnancies and live births. The effectiveness of letrozole priming for the subtypes of OMAs needs further investigation, with studies including greater numbers of cases.

RESEARCH QUESTION: Are there differences in immature oocyte retrieval following luteal phase in-vitro maturation (IVM) compared with follicular phase IVM in women with oocyte maturation abnormalities (OMAs). DESIGN: From January 2019 to May 2023, a retrospective cohort study at a private IVF centre included 36 women with 53 IVM cycles in Group 1 (follicular phase) and 24 women with 32 IVM cycles in Group 2 (luteal phase). Additionally, nine women had both follicular and luteal phase IVM cycles for intracycle variability analysis. RESULTS: There were no differences in oocyte maturation stages between the groups at collection. Group 1 and Group 2 exhibited comparable median metaphase II oocyte rates per patient at 48 h after collection [40.0%, interquartile range (IQR) 0.0-66.7% versus 22.5%, IQR 0.0-52.9%] (Pâ¯=â¯0.53). The median fertilization rate in Group 1 (66.7%, IQR 50.0-66.7%) was found to be comparable with that in Group 2 (66.7%, IQR 50.0-66.7%). There were no significant differences in the yielded embryo grades and pregnancy rates between the groups. Comparing follicular and luteal phase IVM within the same menstrual cycle in nine patients, no differences were observed in metaphase II oocyte maturation rates (P > 0.05). CONCLUSIONS: This study found no significant differences in oocyte maturation, fertilization rate, embryo quality or pregnancy outcomes between luteal phase and follicular phase IVM in women with OMAs. These findings suggest that luteal phase IVM can be used similarly to follicular phase IVM, offering a potential avenue to enhance embryo yield for women with OMAs.

AIM: Microbiota of the reproductive tract may be associated with unexplained infertility in women. We aimed to determine the derangements of vaginal and endometrial microbiota related to unexplained infertility by real-time polymerase chain reaction (real-time PCR) microbiota analyses of vaginal and endometrial samples of the unexplained infertility patients and fertile women. MATERIALS AND METHODS: Twenty-six women with unexplained infertility and 26 age-matched fertile women were included. Vaginal and endometrial samples were obtained in the mid-menstrual cycle for analysis by quantitative real-time PCR method. RESULTS: The proportion of lactobacilli-impaired microbiota was significantly higher in the vaginal samples of unexplained infertility patients (76.9% vs. 26.9%; p < 0.001). Those with impaired lactobacilli microbiota of vaginal samples had an increased risk of 9.048 times for infertility than those with normal lactobacilli microbiota. In addition, the mean lactobacilli/total bacterial mass (TBM) ratio in the vaginal samples was significantly lower in the unexplained infertility patients (38.2% vs.76.3%; p = 0.001). CONCLUSION: The present study results supported the role of vaginal and endometrial microbiota derangements in unexplained infertility. Many time-consuming and invasive methods are currently used in the diagnosis of infertility. Our study showed that the quantitative determination of lactobacilli/TBM ratio in vaginal specimens, a less invasive and easily obtainable method, could be used as a diagnostic test during the workup of couples with unexplained infertility.

Balanced vaginal microbiota and, as a continuum, cervical canal microbiota help prevent reproductive disorders, including recurrent miscarriage (RM). In a significant proportion of couples with RM, routine diagnostic workup cannot find any manageable cause, leading to a requirement for new diagnostic tools. In the present study, we determined the quantitative composition of the microbiota of the vagina and cervical canal, assessed by real-time polymerase chain reaction, in women with RM. It also evaluated their derangements related to the pathogenesis of RM, and thus the suitability of this test as a diagnostic tool for managing RM. Vaginal and cervical canal specimens of 25 women with RM and 25 healthy volunteers were collected. The test results revealed information about the total vaginal bacterial biomass by measuring the abundance of Lactobacillus spp.; other bacteria; and pathogens, including Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma (urealyticum + parvum), and Candida spp. Overall, the findings of this study implied the abundance of Lactobacillus spp. decreased in women with RM with an increase in the abundance of other microorganisms in accordance with the reduction in the abundance of Lactobacillus spp. due to aerobic vaginitis and bacterial vaginosis. Vaginal and cervical canal microbiota need to be considered during the diagnostic workup of women with RM.IMPACT STATEMENTWhat is already known on this subject? Recurrent miscarriage (RM) is a well-known reproductive disorder. Its diagnostic workup is not successful in determining the underlying problem in many cases. Hence, novel diagnostic tools based on real-time polymerase chain reaction (PCR) are needed for evaluating reproductive microbiota, which are considerably reliable, to satisfy the expectations of women with RM.What do the results of this study add? Overall, the decrease in the abundance of Lactobacillus spp. was found to be related to RM, and the patterns of the presence of other microorganisms were in accordance with the reduction in the abundance of Lactobacillus spp. These findings suggested an important role of vaginal and cervical canal microbiota in the pathogenesis of RM.What are the implications of these findings for clinical practice and/or further research? Additional research is warranted to elucidate the functional impact of altered components of the microbiota of vaginal and cervical canals on the physiology of the local cervical canal and its participation in the microbiota of the endometrial cavity, especially regarding unsuccessful pregnancies as a result of the disturbed physiology of the local endometrial microenvironment. However, possible applications of real-time PCR-based tests for the screening of subclinical infections in clinical practice require the performance of further investigations in patients with RM.

This study aimed to evaluate the relationship between intrahepatic cholestasis of pregnancy (ICP) and Vitamin D and B12 levels. The study was a retrospective, cross-sectional, case-control study that evaluated 92 ICP cases and 102 pregnant women without any additional disease. ICP cases were grouped as mild and severe according to their total bile acid (TBA) levels, and their relationship with Vitamin D and B12 levels and perinatal outcomes was evaluated. Vitamin D and B12 levels of the ICP group were significantly lower than those of the control group. There was a moderate negative correlation between TBA and Vitamin D levels and a low negative correlation between TBA and Vitamin B12 levels. Adverse neonatal outcomes were significantly higher in the severe ICP group than in the mild ICP group. IMPACT STATEMENTWhat is already known on this subject? The pathophysiology of ICP, which can lead to adverse perinatal outcomes, is not yet fully understood, and there is no preventive treatment.What do the results of this study add? This study showed that Vitamins B12 and D levels were low in women with ICP and that TBA levels were negatively correlated with Vitamin D and B12 levels.What are the implications of these findings for clinical practice and/or further research? This study may guide future studies in terms of explaining the etiopathogenesis of ICP and developing treatment options.

INTRODUCTION: Our study aims to evaluate the perinatal outcomes in twin pregnancies diagnosed with intrahepatic cholestasis of pregnancy (ICP) and to compare these with normal healthy twin pregnancies for perinatal outcomes. The second outcome of the study was to determine whether in vitro fertilization-embryo transfer (IVF-ET) affects the perinatal outcome in ICP patients. MATERIALS AND METHODS: In this study, 59 ICP and 641 healthy twin pregnancies were compared for perinatal outcomes retrospectively. According to the mode of conception, the twin pregnancies with ICP were divided into 2 groups. The twin pregnancies with ICP who were conceived with IVF were referred to as the IVF-ET group. The twin pregnancies with ICP who were conceived spontaneously or by ovulation induction and intrauterine insemination (IUI) were referred to as the non-IVF-ET group. RESULTS: Twin pregnancies with ICP give birth significantly earlier than normal twin pregnancies (p Ë 0.001). The diagnosis of ICP occurred significantly earlier in the IVF-ET pregnancy with ICP than in the non-IVF-ET group. In twin pregnancies with IVF-ET, patients delivered significantly earlier than in the non-IVF-ET group (p=0.002). Twin pregnancies with ICP were found to have significantly higher rates of meconium-stained amniotic fluid, postnatal intubation, and admission to the neonatal intensive care unit (NICU) than healthy twin pregnancies. CONCLUSIONS: ICP is a risk factor for preterm delivery in twin pregnancies. In addition, ICP develops earlier and more frequently in twin pregnancies from IVF-ET than in those from non-IVF twin pregnancies, and the disease may be more serious.

We conducted a prospective study to assess serum melatonin as a biomarker to predict the development of late-term and postterm pregnancies and spontaneous beginning of labor in women with term pregnancies. Population of this prospective study included pregnant women with late-term and postterm pregnancies and term pregnancies as controls. In these study groups, serum melatonin concentrations were measured in women with or without labor and their perinatal data were collected. In the postterm pregnancies without labor, the lowest median melatonin concentrations were measured (p<0.05). In the late-term and postterm pregnancies with and without labor, the median serum melatonin concentrations were significantly lower than term ones (p<0.05). In the term pregnancies with labor, the highest median melatonin concentration was measured (p<0.05). A serum melatonin concentration≤34 pg/mL as a cut-off value determines late-term and postterm pregnancy with a sensitivity of 80.4% and a specificity of 81.4%. A serum melatonin concentration>29.35 pg/mL as a cut-off value determines presence of labor with a sensitivity of 82.1% and a specificity of 55.0%. In women with term pregnancies, with the measurement of serum melatonin, it is possible to predict the development of late-term and postterm pregnancies and whether these pregnancies undergo spontaneous labor. With further studies, these findings need to be supported before their routine clinical use.

INTRODUCTION: Intrahepatic cholestasis of pregnancy is a pregnancy-specific liver disease that usually emerges during the third trimester of pregnancy. It is characterized by itching and elevated serum total bile acid levels, and it may lead to severe fetal complications. This study aimed to investigate the role of interleukin-8, a pro-inflammatory cytokine; interleukin-10, an anti-inflammatory cytokine; and melatonin in intrahepatic cholestasis of pregnancy. MATERIALS AND METHODS: This prospective, case-controlled study was conducted with 51 women with intrahepatic cholestasis of pregnancy (40 mild and 11 severe cases) and 43 healthy pregnant women. Serum interleukin-8, interleukin-10, and melatonin levels were evaluated. RESULTS: Melatonin and interleukin -10 were significantly lower in subjects with intrahepatic cholestasis of pregnancy (p=0.001; p=0.001, respectively p<0.05). Interleukin-8 levels were found to be significantly higher in the cholestasis group than control group (p=0.001, p<0.05). CONCLUSIONS: Because interleukin-8, interleukin-10, and melatonin were found to be significantly correlated with intrahepatic cholestasis of pregnancy, we believe this finding could shed light on the etiology of the disease.

INTRODUCTION: the aim of this study was to determine whether maternal serum IL-6 and postnatal melatonin levels change with the mode of delivery. MATERIALS AND METHODS: a prospective controlled study was performed on pregnant women (17-43 years) over 37 weeks of pregnancy. Patients were divided into three groups according to the route of delivery: Group 1) 30 women delivering by vaginal route; Group 2) 30 delivering by iterative cesarean section (CS); Group 3) delivering by emergency CS. Maternal serum IL-6 levels were measured before and after delivery, and maternal colostrum melatonin levels after delivery, and the results between the 3 groups compared. RESULTS: pre-delivery and post-delivery maternal serum IL-6 levels were significantly higher in patients who delivered vaginally than in patients who delivered by the abdominal route (p<0.01). Maternal colostrum melatonin levels of patients after delivery were significantly higher in patients who delivered vaginally (32.88±7.16 ng/L) than in patients who delivered by elective and emergent cesarean deliveries (24.86±2.40 ng/L and 23.73±4.03 ng/L, respectively) (p<0.01). CONCLUSION: These data support, should there ever be a further need, the benefit of vaginal delivery over cesarean section, in which cytokine and melatonin levels are reduced compared to vaginal delivery.

OBJECTIVE: Spontaneous ovarian hyperstimulation syndrome (SOHSS) is an extremely rare complication that deserves a multidisciplinary approach together with a thorough investigation for the correct diagnosis of the underlying pathology. The aim of this study was to present a case of severe SOHSS resistant to all interventions and to discuss the available interventions to overcome such a rare and serious clinical situation. CASE REPORT: We report a case of severe, life-threatening spontaneous OHSS with a normal nine weeks singleton pregnancy in a 25-year-old nulliparous woman, which resulted with pregnancy termination and continuation of disease progression until the dose of cabergoline was increased to 1.5 mg/day. CONCLUSION: This case report emphasizes that patients with life-threatening SOHSS resistant to all medical and surgical interventions may benefit from higher doses of cabergoline. Although spontaneous OHSS is extremely rare, it is potentially a life-threatening clinical entity in its severe form and needs time management and detailed examination of the underlying causes.

BACKGROUND: The aim of this prospective cohort study was to investigate the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the cerebrospinal fluid (CSF) of pregnant women with neurological symptoms due to coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: This research was carried out in the Samsun University. Department of Anesthesiology and Reanimation from December 2021 to May 2022. Pregnant women exhibiting neurological symptoms linked to COVID-19 were assigned to one of the two groups, depending on the severity of the disease-mild (Group 1) and severe (Group 2). Specimens were collected from patients' CSF, and the presence of SARS-CoV-2 was investigated using the reverse transcription-polymerase chain reaction (RT-PCR) method. SARS-CoV-2 was also investigated using RT-PCR by collecting oropharyngeal swab specimens from infants in the first 6 h after birth. RESULTS: One hundred fifty patients were enrolled, 75 in both groups. The most frequent neurological symptoms were dizziness in Group 1 (52%) and headache in Group 2 (32%). No significant differences were determined in neutrophils, lymphocytes, hemoglobin, leukocytes, platelets, ferritin, D-dimer, C-reactive protein, prothrombin time, aspartate aminotransferase, alanine aminotransferase, creatinine, sedimentation, or fibrinogen values. SARS-CoV-2 was identified in the CSF of only one patient, from Group 2. Infant oropharyngeal swab specimens tested negative for SARS-CoV-2 using RT-PCR. CONCLUSION: This study indicates that the detection of SARS-CoV-2 in CSF via RT-PCR is rare. We suggest that neurological symptoms linked to SARS-CoV-2 are not caused by direct invasion and that other etiologies represent more likely mechanisms.

Objective: To review the outcomes of in vitro maturation (IVM) and in vitro fertilization (IVF) in women with empty follicle syndrome (EFS). The study evaluated the genetic underpinnings of EFS by analyzing mutations. Materials and Methods: This retrospective case series involving 17 women with EFS over at least 2 IVF cycles was conducted. The study also employed whole-exome sequencing to analyze the genetic mutations. The treatment approaches included letrozole-primed IVM, follicle-stimulating hormone (FSH)-human chorionic gonadotrophin (hCG)-primed IVM, and conventional IVF. Results: The average female age was 31.5±4.6 years, and the duration of infertility was 7.3±3.5 years. Four patients underwent IVF. IVM oocyte collections yielded oocytes in 12 of 13 subjects. Of these, 75% (9/12) yielded MII oocytes after 48 h of IVM media incubation. Six subjects had fertilized embryos, resulting in a 40.9% intracytoplasmic sperm injection (ICSI) fertilization rate (9 embryos/22 MII oocytes). Genetic analysis revealed mutations in seven patients. This study demonstrated the partial efficacy of letrozole-primed IVM plus growth hormone and FSH-hCG primed IVM protocols. No pregnancies or live births were recorded after IVM. One ongoing pregnancy post-IVF and one spontaneous live birth were observed. Conclusion: Inter-cycle variabilities were observed in women with oocyte maturation abnormalities (OMAs). Almost all patients with EFS had oocytes collected during IVM following IVF. These oocytes have limited potential for maturation, fertilization, and live birth, as demonstrated by the low rates observed after IVM culture and ICSI. These conditions are observed in OMAs due to defects in the oocyte machinery. The proposed flowchart provides a comprehensive classification approach for various forms of EFS.
RESUMEN
Objective: The purpose of this research is to investigate the relationship between zonulin levels and diminished ovarian reserve (DOR), and to evaluate the potential role of autoimmunity in the development of DOR. The study contributes to the understanding of the pathogenesis of DOR, which can be an unexpected diagnosis often associated with infertility and unpleasant physical symptoms in women. Materials and Methods: This cross-sectional study was conducted by scanning 224 patients. The demographic characteristics of the patients were recorded. Antral follicle counts of the patients were determined by ultrasound, and Anti-Mullerian hormone (AMH) levels were examined. Follicle-stimulating hormone (FSH), luteinizing hormone, estradiol, AMH measurement, and antral follicle counts were made on the 2nd or 3rd day of menstrual bleeding. The zonulin levels of the participants were measured by the ELISA method. The patients were divided into two groups according to the presence of DOR. The patients' demographic characteristics and hormone levels were compared between these two groups, serum zonulin levels were examined, and the relationship between other hormone parameters and zonulin was investigated. Results: When the median ages of the patients in both groups were compared, the median age of patients with DOR was 38 years, significantly higher (p<0.001) than the median age of those without DOR, which was 27 years. The median zonulin levels of both groups were compare; it was observed that it was 19.71 ng/mL in the group with DOR and 11.03 ng/mL without DOR, and a statistically significant difference was found between the zonulin levels of the patients in both groups (p<0.001). A moderate inverse correlation (p<0.001) between patients' zonulin and AMH levels, and a moderate correlation between FSH levels (p<0.001). Conclusion: In conclusion, zonulin levels of patients with DOR were higher than women without DOR. Evaluation of zonulin levels may also be considered during the diagnosis of DOR.
RESUMEN
OBJECTIVES: Poor overall neonatal outcomes, small neonatal head circumference, neonatal hypoglycemia, need for Neonatal Intensive Care Unit and late-onset neonatal sepsis are more common in adolescents. The aim of this study is to draw attention to the outcomes of adolescent pregnancies. MATERIAL AND METHODS: This retrospective study was conducted in adolescent singleton pregnancies with maternal age < 15 years (n = 20, group 1), 16-19 years (n = 1929, group 2), and 20 years (n = 866, group 3). Age, gravidity, parity, and body mass index (BMI) measurements of mothers; mode of delivery, maternal and neonatal outcomes were evaluated and compared. RESULTS: The rate of preterm birth, postpartum hemorrhage, asymmetrical intra-uterine growth restriction (IUGR, as 3% percentile), macrosomia, and height of newborn of Group 3 was significantly higher. The rate of asymmetrical IUGR (as 10% percentile) was significantly lower in Group 3. The rate of severe preeclampsia and cesarean section was significantly higher in Group 3. The rate of Small for Gestational Age newborn, neonatal hypoglycemia, and late-onset neonatal sepsis was significantly higher in Group 1. CONCLUSIONS: Neonatal problems with poor obstetric outcomes are common in adolescent pregnant women, so that a family planning and baby care social trainings are important in achieving good long-term maternal and neonatal outcomes.

Objective: Preeclampsia is a highly morbid disease of placental origin, life-threatening condition for both a pregnant woman and her fetus. Cadherin 6 and 11 are adhesion molecules that play an important role in trophoblastic development and placentation. In our study, we investigated the change in serum cadherin 6 and 11 levels in pregnant women with preeclampsia. Materials and Methods: Pregnant women with preeclampsia were selected and compared with healthy women (as a control group) for a one-year study. The serum alanine aminotransferase, aspartate aminotransferase, and cadherin levels 6 and 11 of participants were analyzed and compared. Results: A total of 189 pregnant women were subdivided into 2 groups as preeclamptic (n=94) and women with healthy pregnancy (n=95). The cadherin 6 and cadherin 11 levels of the preeclamptic patients were significantly higher than those in the control group (p=0.001), and they were found to be significantly higher mainly in patients with early-onset and severe preeclampsia group (p=0.001). The cut-off cadherin 6 and 11 values for severe preeclampsia were found as 98.174 ng/mL and 1.92 ng/mL; with sensitivity of 88.3% and 84% respectively (p=0.001). Conclusion: The data analysis showed elevated serum cadherin 6 and 11 levels associated with the severity and early onset of pre-eclampsia. Serum cadherin 6 and 11 levels can be a candidate marker for the prediction of preeclampsia.
RESUMEN
The objective of this study was to assess the value of serum leptin, adiponectin, apelin, and ghrelin as biomarkers for the prediction and diagnosis of intra-hepatic cholestasis (ICP). This prospective study included pregnant women in the third trimester of pregnancy: 63 with ICP, 48 and 15 of whom had mild and severe disease, respectively, and 32 as controls. ICP women had increased median levels of serum leptin, adiponectin, apelin, and ghrelin compared to the controls (p < 0.05). These biomarkers meaningfully changed regarding the severity of ICP: While leptin was reduced, apelin and ghrelin were increased, and adiponectin was increased somewhat. To predict and diagnose ICP, the predictive values of serum leptin, adiponectin, and apelin need to be accepted as comparable, with moderate to high sensitivity and specificity; however, the predictive value of serum ghrelin was somewhat lower. More research is needed to clarify the potential properties of adipokines to gain acceptance as a predictive or diagnostic biomarker for ICP.

Oocyte maturation abnormalities (OMAS) are a poorly understood area of reproductive medicine. Much remains to be understood about how OMAS occur. However, current knowledge has provided some insight into the mechanistic and genetic origins of this syndrome. In this study, current classifications of OMAS syndromes are discussed and areas of inadequacy are highlighted. We explain why empty follicle syndrome, dysmorphic oocytes, some types of premature ovarian insufficiency and resistant ovary syndrome can cause OMAS. We discuss live births in different types of OMAS and when subjects can be offered treatment with autologous oocytes. As such, we present this review of the mechanism and understanding of OMAS to better lead the clinician in understanding this difficult-to-treat diagnosis.
RESUMEN
OBJECTIVE: The objective of this study is to determine if the second-trimester serum afamin is a reasonable predictor of preeclampsia (PE). METHODS: In this nested case-control study, all pregnant women were screened by second-trimester screening test between 15 and 20 weeks of gestation and serum samples were collected and stored at -80 °C for biochemical analysis. All available stored samples from pregnant women who subsequently developed PE were thawed and the concentrations of afamin in the serum were measured. Control cases, chosen randomly from the same cohort whose blood was collected and stored in the same period as with the study group, who did not develop PE. Afamin levels were expressed ng/mL. Logistic regression was used to calculate adjusted odds ratio (aORs) for the prediction of PE. RESULTS: A total of 39 women with PE and 46 controls were studied. Afamin levels were found to be significantly higher during the second trimester in women who developed PE compared to the control group. Afamin, at a cut-off level of 96.2 ng/mL, the aORs for PE was 28.6 (95% CI: 7.458-110.193). After adjustment for BMI, age, smoking, the aORs for PE was 65.6 (95% CI: 11.6-371.4; p = .001). CONCLUSION: High levels of afamin in the early weeks of gestation in patients going on to develop PE later may be promising as a potential marker to predict PE in the first and second trimesters.

OBJECTIVES: The aim of this study is to show whether bladder filling with saline before percreta surgery diminish the rate of bladder injuries or not. A secondary aim was to check the operative and postoperative outcomes between the cases of filled and unfilled bladder in placenta accreta surgery. METHODS: This retrospective multicentric cohort study involved 88 patients who were diagnosed with placenta accreta and underwent cesarean hysterectomy between 1 January 2009 and 1 January 2019. Women who had cesarean hysterectomies due to the indication of placenta accreta and did not have bladder filling were used as the control group. RESULTS: Eighty-eight women met the inclusion criteria. Forty-nine of the cases, the bladder was filled with saline solution before the operation, whereas in 39 the bladder was not filled. Intraoperative bladder injury occurred less in patients with preoperative filled bladders than in patients with unfilled bladders (p = .015; p < .05). There was a statistically significant difference between the duration of surgery according to bladder inflation (p = .001; p < .01); in the filled bladder group, the operation time was shorter than in the unfilled group. CONCLUSIONS: Filling the bladder with 200 ml saline solution before starting a cesarean section is an easy and useful technique that can reduce the possibility of bladder injury in placenta accreta surgery.

OBJECTIVE: Midregional pro-adrenomedullin (MR-proADM) and matrix metalloproteinase-2 (MMP-2) are such proteins, that decreased levels are demonstrated in defective placental functions, as preeclampsia. The aim of the study is to compare maternal serum MR-proADM and MMP-2 levels across pregnancies with intrauterine growth restriction (IUGR), small for gestational age (SGA) and appropriate for gestational age (AGA), to biochemical screen the difference between SGA and IUGR. MATERIALS AND METHODS: 180 pregnant women were enrolled in a cross-sectional study: sixty pregnancies diagnosed for IUGR were included in group 1 (IUGR group), sixty pregnancies with SGA were in Group 2 (SGA group) and sixty pregnancies diagnosed for AGA, as control group. Maternal venous blood samples were collected at the time of enrollment, to assess serum MR-proADM and MMP-2 levels, by enzyme-linked immunosorbent assay (ELISA). RESULTS: The mean maternal serum MR-proADM and MMP-2 levels were lower in the IUGR group than in the SGA and AGA groups (p < .001 and p < .001). Maternal serum MR-proADM and MMP-2 cutoffs of 29.985 pg/mL and 1.875 ng/mL were found to be optimal to distinguish IUGR, with sensitivity of 98.3% and 98.3%, specificity of 83.3% and 89.2%, respectively. CONCLUSION: Maternal serum MR-proADM and MMP-2 levels were significantly lower in pregnancies with IUGR. Maternal serum MR-proADM and MMP-2 measurements could be used to distinguish IUGR pregnancies from SGA pregnancies.
