Serum levels of kynurenine in pregnancies with fetal growth restriction and oligohydramnios.

OBJECTIVES: Kynurinine (KYN) and its metabolites, which are released during the metabolism of tryptophan, an essential amino acid, have many important functions, such as cellular energy production, regulation of vascular tone, and regulation of the immune system. In this study, we aimed to detect serum KYN levels, which may be an indicator of KYN pathway activity, in idiopathic fetal growth restriction (FGR) and oligohydramnios cases whose pathophysiology is known to be affected by multiple factors, such as placental hypoperfusion, immune dysregulation, and maternal nutrition disorder, and to investigate their relationship with these common obstetric complications. METHODS: This cross-sectional case-control study was carried out in the antenatal outpatient clinics of Ankara City Hospital between July and December 2021. While the study group consisted of pregnant women with idiopathic isolated FGR and oligohydramnios, the control group consisted of low-risk patients who did not have any problems. The clinical features of the patients, such as age, body mass indexes, and gestational week, were recorded by measuring basic laboratory parameters and serum KYN levels. RESULTS: A total of 110 patients were included in this study. The patients were divided into three groups: FGR, oligohydramnios, and the control group. There was no significant difference between the patients' ages, weeks of gestation, or body mass indexes. Serum KYN level was calculated as 57.8 ± 13.4 pg/mL in IUGR, 75.3 ± 10.8 pg/mL in oligohydramnios and 95.1 ± 13.3 pg/mL in the control group (p<0.001). CONCLUSIONS: Serum KYN levels were lower in pregnant women complicated with FGR and oligohydramnios more prominently in pregnant women diagnosed with FGR than in normal pregnancies. The results suggest that KYN plays an important role in either the etiopathogenesis or the response to these two obstetric pathologies.

Evaluation of the vestibular system with video head impulse test in pregnant women with hyperemesis gravidarum.

AIM: We aimed to evaluate the semicircular canal functions of the vestibular system in pregnant women with hyperemesis gravidarum. METHODS: This is a prospective case-control study. Among pregnant women in their first trimester (<14. gestational weeks) who presented to our outpatient clinic, 36 patients diagnosed with hyperemesis gravidarum defined as persistent nausea and vomiting requiring intravenous hydration or loss of at least 5% of prepregnancy weight and 34 healthy pregnant without nausea and vomiting were included. Otorhinolaryngologic examination and video head impulse test (vHIT) was performed to all patients. Vestibular-ocular reflex (VOR) gain and gain asymmetry were assessed between groups. RESULTS: The VOR gains in each semicircular canal did not differ between hyperemesis and control groups. Using a VOR gain cut-off value of 0.8, the groups were compared in terms of the frequency of low values. In the hyperemesis group, abnormally low gain values of left anterior canal were more frequently observed than in the control group (32 [88.9%], 22 [64.7%], respectively, P = 0.01). In left anterior-right posterior (LARP) plane VOR gain asymmetry was higher in hyperemesis group (13.5 [1.0-71.0], 6.0 [0.0-35.0], P = 0.001). No significant gain asymmetry was detected between the groups in the other planes. CONCLUSION: Semicircular canal functions were not abnormal globally in women with hyperemesis gravidarum. However, higher LARP plane asymmetry and low LA gain in women with hyperemesis suggests need for further research to clarify functional role of vestibular system on hyperemesis gravidarum.

Does an increased number of cesarean sections result in greater risk for mother and baby in low-risk, late preterm and term deliveries?

OBJECTIVE: To compare surgical complications and maternal and neonatal outcomes of low-risk, late preterm and term pregnant women who have had one or two previous cesarean sections (CSs) with those who have had three or more CSs. METHODS: We conducted a retrospective study of 850 patients undergoing repeat CS at a tertiary level maternity hospital in Ankara, Turkey. Of those, 380 had previously undergone one or two CSs (Group-I: second or third CS) and 470 had previously undergone three or four CSs (Group-II: fourth or fifth CS). Outcomes and complications were compared between the groups. RESULTS: The two groups were statistically significantly different in terms of maternal age, parity, body mass index, maternal weight gain during pregnancy, and length of hospital stay (all p<0.001). Although the prevalence of intraperitoneal adhesions and placenta previa was higher in Group-II than in Group-I (p<0.001), there was no statistically significant difference in terms of cesarean hysterectomy and adjacent organ injuries (p>0.05). There were also no significant differences between the groups in terms of neonatal outcomes (p>0.05). CONCLUSION: Although the increase in the number of CSs appears to be associated with intraperitoneal adhesions and placenta previa, adverse maternal and neonatal outcomes were not observed in those women with low-risk pregnancies who underwent CS for the fourth or fifth time. Therefore, fourth and fifth CSs may be considered relatively safe surgical procedures in this cohort.

Pregnancy physical activity questionnaire (PPAQ): reliability and validity of Turkish version.

[Purpose] The aim of this study was to translate the Pregnancy Physical Activity Questionnaire into Turkish and test its reliability and validity among Turkish pregnant women. [Subjects and Methods] The subjects were 204 healthy, single pregnant women between the ages 18 and 40 who volunteered to participate in this study. Reliability was evaluated by measuring the one-week test-retest reliability with the intraclass correlation coefficient and Pearson's correlation analysis. Concurrent validity was examined by comparing the Pregnancy Physical Activity Questionnaire with the long form of the International Physical Activity Questionnaire and step counts with pedometer. [Results] The mean age of the participants was 28.23±4.94 years, and the mean for BMI was 26.09±4.40. For test-retest reliability, r values were respectively 0.961, 0.934, 0.957 and 0.981 for self-reported sedentary, light, moderate, and vigorous activity, respectively. Intraclass correlation coefficient scores ranged from 0.924 to 0.993. For validity, the Pearson's correlation coefficients between the Pregnancy Physical Activity Questionnaire and long form of the International Physical Activity Questionnaire ranged from moderate (r = 0.329) to high (r = 0.672). The correlation value between the total score of the Pregnancy Physical Activity Questionnaire and the step counts was 0.70. [Conclusion] The Turkish version of the Pregnancy Physical Activity Questionnaire is a valid and reliable tool for measurement of the physical activity level of pregnant women.

Behçet's disease and pregnancy: a retrospective analysis of course of disease and pregnancy outcome.

AIM: Behçet's disease (BD) is a rare, chronic, multisystemic disease of unknown cause. BD is characterized by mucocutaneous, ocular, vascular and central nervous system manifestations and is also associated with thrombogenicity. In this retrospective analysis we investigated the relation between gestation and BD. MATERIAL AND METHODS: This retrospective study consisted of 49 pregnancies in 24 patients with BD between January 2008 and June 2013. The following clinical and demographic data were obtained: maternal age, obstetric history, pregnancy outcome, and maternal and neonatal complications during pregnancy following diagnosis of BD. To avoid recall bias, the following data were collected only in the recent pregnancy of each patient: disease activity and use of medications during pregnancy. RESULTS: Sixty-three pregnancies occurred in this group and 52 of them were after the diagnosis. Mean age of the patients at diagnosis was 21.4 years. The duration of BD during pregnancy was 7.2 years. Fourteen patients (58.3%) had no symptoms during recent pregnancy. No change was observed in the disease activity during pregnancy in eight patients. Disease activity was aggravated in two patients. The rate of vascular complications was higher in pregnancies of patients with BD. The rates of stillbirth, pre-eclampsia, preterm delivery and intrauterine growth restriction did not differ between the groups. Perinatal mortality and neonatal intensive care unit admissions as well as low birthweight infants were also similar between groups. CONCLUSION: Patients with BD had a higher rate of vascular complications during pregnancy; however, other obstetric complications were not increased and neonatal outcomes were not negatively influenced by BD.

Prolidase as a marker of fibrogenesis in idiopathic primary ovarian insufficiency.

OBJECTIVES: To evaluate the serumlevel of prolidase,which isa marker of fibrogenic activity, in women with idiopathic primary ovarian insufficiency (POI). STUDY DESIGN: This is a prospective case-control study. Serum prolidase level was compared between the study group including 68 women with POI and control group including 65 normally menstruating women. Serum proline and hydroxyproline levels were also compared. Correlation analyses were performed between the prolidase level and POI related parameters including estradiol (E), follicle stimulating hormone (FSH), anti-mullerian hormone (AMH) levels, and presence of POI family history. RESULTS: Serum prolidase and proline level were significantly increased in women with the diagnosis of POI compared to the control group (1082.57 (147.53) vs 981.13 (223.26) U/L, 233.30 (83.16) vs 218.94 (82.59) µmol/L, respectively). Prolidase level found to have significant correlations with AMH, E, FSH levels, and presence of POI family history (r = -0.49, p = 0.001; r = -0.39, p = 0.001; r = 0.42, p = 0.001; r = 0.22, p = 0.01; respectively). In receiver operating characteristics analysis, prolidase was shown to be a discriminative factor for POI at 1031.14 U/L cut-off value with 75 % sensitivity and 65 % specificity. Thearea under curve was 0.71 [(95 % CI: 0.62-0.79), p = 0.001]. CONCLUSION: The current study revealed increased prolidase level in women withPOI. Serum prolidase level was also negatively correlated with the serum AMH level. Considering the present findings,prolidase may be a candidate molecule in assessment of POI cases.

Obstetric outcomes of 297 women treated for vaginismus.

OBJECTIVE: Vaginismus is a disease characterized by vaginal spasms that impede sexual penetration and lead to sexual dysfunction. The association between this disease and infertility is quite well acknowledged. This paper aims to assess the obstetric outcomes and patient characteristics of vaginismus-treated women. STUDY DESIGN: This cross-sectional research comprised 297 vaginismus patients who were effectively treated. METHODS: The following information was collected: age, degree of education, occupation, length of marriage, and obstetric history (primigravida, multigravida, and previous abortions). Following pregnancy, the following data were collected: The results of pregnancy, obstetrics, and neonatology, such as maternal age, gestational age, and birth weight. As obstetrical outcomes, miscarriage, early delivery, hypertension, and fetal loss were recorded. In addition, the mode of delivery (cesarean section vs vaginal birth), reasons for selecting it, analgesic techniques, and potential problems during or after delivery were evaluated. RESULTS: The mean maternal age was 29.2 ± 4.7 years, and the pregnancy rate was 86.86% (n = 258). 258 individuals were reported to have had at least one term pregnancy and delivery. In the feedback for vaginismus, no recurrence was reported 16 weeks after hospital release. CONCLUSION: Vaginismus patients should be treated prior to being deemed infertile, and other fertility treatments should be attempted. Moreover, the caesarean delivery rates of individuals with treated vaginismus are the same as those of the general population. Vaginal delivery after vaginismus treatment seems to be safe, with no increased perineal morbidity or vaginismus recurrence.

Obstetric Outcomes among Syrian Refugees: A Comparative Study at a Tertiary Care Maternity Hospital in Turkey.

OBJECTIVE: The aim of this study was to analyze and compare obstetric and neonatal outcomes between Syrian refugees and ethnic Turkish women. METHODS: Retrospective, observational study. A total of 576 Syrian refugees and 576 ethnic Turkish women were included in this study, which was conducted between January 2015 and December 2015 at a tertiary maternity training hospital in Ankara, Turkey. The demographic characteristics, obstetric and neonatal outcomes were compared. The primary outcomes were pregnancy outcomes and cesarean rates between the groups RESULTS: The mean age was significantly lower in the refugee group (p < 0.001). Mean gravidity, proportion of adolescent pregnancies, proportion of pregnant women aged 12 to 19 years, and number of pregnancies at < 18 years were significantly higher among the refugee women (p < 0.001). Rates of antenatal follow-up, double testing, triple testing, gestational diabetes mellitus (GDM) screening, and iron replacement therapy were significantly lower in the refugee group (p < 0.001). The primary Cesarean section rate was significantly lower in the refugee group (p = 0.034). Pregnancies in the refugee group were more complicated, with higher rates of preterm delivery (< 37 weeks), preterm premature rupture of membranes (PPROM), and low birth weight (< 2,500 g) when compared with the control group (4.2% versus 0.7%, p < 0.001; 1.6% versus 0.2%, p = 0.011; and 12% versus 5.8%, p < 0.001, respectively). Low education level (odds ratio [OR] = 1.7, 95% confidence interval [CI] = 0.5-0.1), and weight gain during pregnancy (OR = 1.7, 95% CI = 0.5-0.1) were found to be significant indicators for preterm birth/PPROM and low birthweight. CONCLUSION: Syrian refugees had increased risks of certain adverse obstetric outcomes, including preterm delivery, PPROM, lower birth weight, and anemia. Several factors may influence these findings; thus, refugee women would benefit from more targeted care during pregnancy and childbirth.

Relationship maternal subcutaneous adipose tissue thickness and development of gestational diabetes mellitus.

OBJECTIVE: We investigated whether the ultrasonographic measurement of maternal subcutaneous adipose tissue (SAT) thickness in the second trimester played a role in predicting gestational diabetes. MATERIALS AND METHODS: This was a prospective cross-sectional study in which 223 women were classified as healthy (n = 177) or as gestational diabetes (n = 46) on the basis of a negative or positive two-step oral Glucose Challenge Test (GCT), respectively. The depth of the abdominal SAT was evaluated by two-dimensional ultrasonography. Body mass index (BMI), waist circumference (WC), and waist/hip ratio were determined. RESULTS: There was a positive strong significant correlation between a 50-g GCT level and BMI, WC, and SAT thickness (p < 0.001). Receiver-operating characteristic curve analysis showed SAT thickness above 16.75 mm predicted gestational diabetes mellitus (GDM) with a sensitivity of 71.7%, a specificity of 57.1%, a positive predictive value of 32.3%, and a negative predictive value of 87.6%. There was a good correlation between SAT, BMI, and WC. CONCLUSION: Increased SAT, BMI, and WC measurements may be helpful in predicting the risk of the development of GDM in pregnant women.

Evaluation of Oxidative Stress in Women with Polycystic Ovarian Syndrome as Represented by Serum Ischemia Modified Albumin and Its Correlation with Testosterone and Insulin Resistance.

Objective Ischemia-mediated oxidative stress and inflammation have been reported to be important contributors to the pathogenesis of polycystic ovary syndrome (PCOS). Ischemia-modified albumin (IMA) is a novel marker generated under ischemic and oxidative conditions and may reflect disease activity in distinct disease states. Therefore, we investigated whether the serum IMA levels are affected in infertile PCOS patients. Methods Forty-six patients with infertile PCOS, 30 patients with unexplained infertility, and 31 age- and body mass index (BMI)-matched controls were included in this cross-sectional study. Biochemical parameters, serum IMA levels, and their correlations with serum testosterone and insulin resistance were determined for each subject. Results In patients with infertile PCOS, the serum IMA levels were significantly elevated (p=0.003) compared with unexplained infertility patients and controls. A correlation analysis suggested that the IMA levels only correlated with the serum free testosterone levels in PCOS patients (r=0.43, p=0.028). Conclusion Elevations in the serum IMA levels in infertile PCOS patients may suggest a possible additional role of oxidative stress mechanisms in disease pathophysiology. Moreover, correlation between serum IMA and testosterone levels may influence the quality of oocytes via alterations in the balance of critical follicular fluid factors in the follicular microenvironment.

Retrospective evaluation of pregnancy outcomes in women with familial Mediterranean fever.

AIM: Familial Mediterranean fever (FMF) is an autosomal recessive condition characterized by periodic attacks of fever, aseptic serositis and synovitis. In this study, we investigated maternal and neonatal outcomes in pregnant patients with FMF. METHODS: This retrospective study consisted of 46 pregnant patients with FMF who attended the perinatology clinic of Dr Zekai Tahir Burak Research and Training Hospital between January 2008 and December 2012. The following clinical and demographic data were obtained by reviewing the patients' medical records: maternal age, colchicine use during pregnancy, obstetric history, pregnancy outcome and maternal and neonatal complications during the current pregnancy. RESULTS: The patients with FMF had higher rates of premature rupture of membranes (PROM) and Cesarean delivery as well as low birth weight infants; however, rates of stillbirth, gestational diabetes, preeclampsia did not differ between the groups. Preterm delivery rates were higher in the study group, but this difference did not reach statistical significance. Patients with pregnancy complications had significantly more basal proteinuria than did patients without complications. Nine patients did not receive colchicine therapy in the previous or current pregnancies. Within this subgroup, four (44.4%) of the patients had a history of two or more previous miscarriages. However, there were only three cases (8.1%) of two or more miscarriages among 37 patients who received colchicine; this difference was statistically significant CONCLUSIONS: FMF leads to higher rates of PROM, recurrent miscarriage and preterm deliveries. Colchicine treatment is safe in pregnancy and may lead to a decreased miscarriage rate.
