RESUMO

OBJECTIVE: The aim of the present study was to evaluate the risk factors for cesarean section (C-section) in low-risk multiparous women with a history of vaginal birth. METHODS: The present retrospective study included low-risk multiparous women with a history of vaginal birth who gave birth at between 37 and 42 gestational weeks. The subjects were divided into 2 groups according to the mode of delivery, as C-section Group and vaginal delivery Group. Risk factors for C-section such as demographic characteristics, ultrasonographic measurements, smoking, weight gain during pregnancy (WGDP), interval time between prior birth, history of macrosomic birth, and cervical dilatation at the admission to the hospital were obtained from the charts of the patients. Obstetric and neonatal outcomes were compared between groups. RESULTS: The most common C-section indications were fetal distress and macrosomia (33.9% [n = 77 and 20.7% [n = 47] respectively). A bivariate correlation analysis demonstrated that mothers aged > 30 years old (odds ratio [OR]: 2.09; 95% confidence interval [CI]: 1.30-3.34; p = 0.002), parity >1 (OR: 1.81; 95%CI: 1.18-2.71; p = 0.006), fetal abdominal circumference (FAC) measurement > 360 mm (OR: 34.20; 95%CI: 8.04-145.56; p < 0.001)) and < 345 mm (OR: 3.06; 95%CI: 1.88-5; p < 0.001), presence of large for gestational age (LGA) fetus (OR: 5.09; 95%CI: 1.35-19.21; p = 0.016), premature rupture of membranes (PROM) (OR: 1.52; 95%CI: 1-2.33; p = 0.041), and cervical dilatation < 5cm at admission (OR: 2.12; 95%CI: 1.34-3.34; p = 0.001) were associated with the group requiring a C-section. CONCLUSION: This is the first study evaluating the risk factors for C-section in low-risk multiparous women with a history of vaginal birth according to the Robson classification 3 and 4. Fetal distress and suspected fetal macrosomia constituted most of the C-section indications.

RESUMO

OBJECTIVE: We compared markers of oxidative stress (OS) in mothers with and without fetal neural tube defects (NTDs). Methods: Pregnant mothers in the second trimester with NTD-affected fetuses and age, gestational age, and body mass index-matched control mothers with unaffected fetuses were included. Maternal serum thiol-disulfide homeostasis parameters and ischemia-modified albumin (IMA) were measured. Results: In 30 affected mothers compared to 31 controls, disulfide levels, disulfide/native thiol, and disulfide/total thiol ratios were higher; native and total thiol levels and native thiol/total thiol ratios were lower (p < 0.001). Mothers with NTD-affected fetuses had higher levels of IMA than controls (p = 0.025). Conclusion: The thiol-disulfide homeostasis balance was shifted in favor of disulfide, suggesting increased thiol oxidation and OS in the second trimester of NTD-affected pregnancies. Maternal levels of IMA, an oxidatively altered form of albumin, thus a measure of OS, were higher in NTD-affected second trimester pregnancies compared to controls.

RESUMO

Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Women with PCOS may have infrequent or prolonged menstrual periods or excess male hormone levels. Metabolomics provide information on early biochemical changes in patients. Our aim was to find potential biomarkers on metabolome level to notice PCOS in adolescents and propose treatment opportunities based on our findings on metabolome level. In this study, Q-TOF LC/MS based analysis of the plasma samples of 15 healthy adolescents as control group (Group C) were compared with the plasma samples of 15 adolescents having PCOS (Group T). Raw chromatograms were processed on XCMS using Isotopologue Parameter Optimization (IPO) to optimize XCMS parameters. Finally, 2288 peaks were found but 84 of them had fold changes >1.5 based on normalized peak areas and they were statistically different (p < 0.05) between the groups. These peaks were subjected to MetaboAnalyst 4.0 - MS Peaks to Pathways utility for putative identification. The final list based on putative identification were evaluated through a clinical perspective and the statistically proved variation on the metabolite profiles of Group T and Group C presented that PCOS directly affected the lipid metabolism in the body or occurred as a result of a deformation in the lipid metabolism. Lower amount of Gamma-Tocopherol and higher amount of Coenzyme Q9, which is a product of incomplete Coenzyme Q10 biosynthesis, in the plasma samples of adolescent PCOS patients encouraged us to suggest larger randomized placebo controlled studies for Gamma-Tocopherol and Coenzyme Q10 supplements on the disease situation since our findings on metabolome level were in an accordance with the previous clinical findings.

RESUMO

OBJECTIVE: The purpose of this study is to evaluate the impact of loop electrosurgical excision procedure (LEEP) and cold-knife conization (CKC) active training model on the surgical education and confidence levels of gynecologists. MATERIALS AND METHODS: The LEEP and CKC hands-on training model consists of sausage, which is 2.5 cm in diameter, as cervix; plastic cup as vagina; foam rubber as posterior and anterior fornices; and cotton plate as the leukoplakia area. In total, 34 participants performed LEEP and CKC procedures on the training model under the guidance of mentors after theoretical lessons about the transformation zone, indications, and surgical techniques of LEEP and CKC. Afterward, a web-based survey was conducted to measure the effectiveness of this surgical model, and participants graded their learning and confidence levels on the same. RESULTS: We evaluated the educational levels of the course, which were based on the basic surgical steps of LEEP and CKC procedures, and the confidence levels of the participants with regard to the previous practice or expertise of LEEP and CKC. Importantly, participants in each group had similar learning gains irrespective of previous practice or expertise. Despite a significantly higher pre-course confidence level of participants who had previously performed LEEP (p<0.001) and CKC (p<0.001) against their non-practitioner counterparts, the post-course confidence levels were similar in each group (p=0.127 and p=0.845, respectively). In both groups, the participants had increased mean confidence scores, which were statistically significant for participants who had not previously performed the procedures (p=0.003, LEEP and p=0.002, CKC, respectively). CONCLUSION: This surgical training model on LEEP and CKC can impart a better level of education in participants, irrespective of their previous expertise/practice.

RESUMO

OBJECTIVES: Phthalates and bisphenol-A (BPA) may pose a risk for human reproduction. Adverse effects of endocrine disturbing chemicals on animal ovaries have been proposed previously. This study was designed to measure the concentrations of phthalate diesters or their metabolites in serum to evaluate their relevance with primary ovarian insufficiency (POI). METHODS: This study was designed as a cross sectional and case-control study. The study group consisted of 30 women diagnosed with POI whereas 30 healthy fertile women without any systemic diseases were recruited as a control group. The two groups were matched with respect to age and body mass index and tobacco smoking. Serum phthalate diesters and BPA levels were measured in both groups. RESULTS: The mean serum level of mono-buthyl phthalate (MBP) was statistically significantly higher in POI group than in control group (8.45 ± 4.2 vs. 5.0 ± 3.47 ng/mL, p < .001). Other serum phthalate metabolites and BPA concentrations were similar among the groups. CONCLUSIONS: Serum levels of BPA and phthalate metabolites are increased in women diagnosed with POI. However, MBP is the most significant one among them. MBP may be a contributing risk factor in the development of POI.

RESUMO

OBJECTIVE: Large uterine or cervical leiomyomas may cause acute urinary retention due to bladder outlet obstruction. We report two cases with acute urinary retention caused by cervical leiomyoma. Myomectomies were performed due to their desire of fertility and frozen-section examinations were reported as benign leiomyomas in both cases. The urinary symptoms completely resolved in two patients following myomectomies. In patients who are admitted with the complaint of acute urinary retention, cervical leiomyomas should be considered in differential diagnosis.

RESUMO

PURPOSE: Neural tube defects (NTDs) are the most common malformations of the central nervous system (CNS). There is continuing research for the identification of risk factors and interventions for prevention of NTDs. The aim of this study was to investigate the maternal second trimester blood levels of selected heavy metals namely, arsenic (As), cadmium (Cd), mercury (Hg), manganese (Mn), nickel (Ni), and lead (Pb) and their possible relation with the occurrence of NTDs. METHODS: Twenty-one healthy second trimester pregnant women with fetuses affected with NTD (cases) were matched with 21 healthy pregnant women with unaffected fetuses (controls) with respect to age, body mass index (BMI), and gestational age. Maternal blood levels of heavy metals were measured after an overnight fasting period. RESULTS: No significant differences were observed in terms of maternal blood levels of As, Cd, Hg, and Ni between NTD-affected and unaffected pregnancies. The blood Pb and Mn levels were found to be higher in pregnant women with a fetus affected with NTD when compared with pregnant women with unaffected fetuses (for Pb, in cases 12.3 ± 5.5 µg/L, in controls 7.8 ± 2.4 µg/L; for Mn in cases 3.6 ± 1.4 µg/L, in controls 2.4 ± 1.0 µg/L, p < .05). CONCLUSIONS: High maternal second trimester blood levels of Pb and Mn during pregnancy are associated with NTDs in the newborn.

RESUMO

Abstract 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.

RESUMO

STUDY OBJECTIVE: This study was designed to evaluate and compare the serum total prostate-specific antigen (PSA) levels in adolescent girls in with and without polycystic ovarian syndrome (PCOS) to show whether evaluation of PSA levels have a diagnostic benefit over existing diagnostic criteria. DESIGN: Case-control study. SETTING: A territory referral center. PARTICIPANTS: A total of 89 (15-19 years) nonobese (body mass index, 18-24.9) adolescents with PCOS (n = 42) and controls without PCOS (n = 47) were enrolled in the study. INTERVENTIONS: Pathophysiological features of PCOS and serum total PSA levels were determined at the time of study enrollment. MAIN OUTCOME MEASURES: Determination, comparison, and diagnostic performance of serum total PSA levels in diagnosis of PCOS in adolescent girls were the main outcome measures of the study. RESULTS: The serum total PSA levels of adolescents with PCOS were detected to be higher than for control participants (0.63 ± 1.38 ng/mL vs 0.48 ± 0.95 ng/mL) without meeting statistical significance (P = .923). There was a correlation between total PSA levels and indices of insulin resistance like the homeostasis insulin resistance model (r = 0.414; P = .010). The serum total PSA level was not a discriminative parameter for diagnosis of PCOS in adolescent girls (area under the curve, 0.559; P = .476). CONCLUSION: The serum total PSA level was not a predictor of PCOS in adolescent girls. This finding might be related to the extemporal nature of tissues capable of PSA production and lack of sufficient exposure interval to hyperandrogenemia, rather than lack of stimulatory relationship between serum androgens.

RESUMO

OBJECTIVE: To evaluate the association of the oxidative stress markers in patients with endometrial polyp. METHODS: A total of forty nine patients between 28-47 years of ages who have a suspect evidence of endometrial polyp on transvaginal sonography were enrolled for the study. Hysterosonography was applied all of the patients and patients then were divided into two groups in terms of their hysteroscopic findings. Group 1(control group, n=27) defined who has no endometrial pathology and group 2 (study group, n=22) defined has one or more endometrial polyp on hysteroscopy with guided biopsy. The diagnosis was established by histopathological examination polyps. The parameters compared between groups were; age, body mass index, catalase (CAT), xsantine oxidase (XO), malondialdehyde (MDA) levels. RESULTS: There were no statistically significant differences between groups in terms of age and BMI. Catalase, xsantine oxidase and malondialdehyde levels were statically significantly different between the groups (p < 0,05). The mean of polyp diameter size were 17.95 ±0.45 mm and the number of the polyp per patient was 1.54 ± 0.67. CONCLUSION: According to our study, serum catalase, xsantine oxidase and malondialdehyde levels may be discriminative parameters for patients with endometrial polyp.
