RESUMO

Background and Objectives: This study aims to compare the neuromuscular structure of the vagina in women with posterior vaginal wall prolapse with the neuromuscular structure of the vagina in women without prolapse, to determine the difference, and to demonstrate the role of neuromuscular structure in the physiopathology of prolapse. Materials and Methods: In this prospective study, women aged between 40 and 75 years who had not undergone any vaginal surgery and had not undergone any abdominal prolapse surgery were included. Thirty-one women diagnosed with rectocele on examination were included in the study group. Thirty-one patients who underwent vaginal intervention and hysterectomy for reasons other than rectocele (colposcopy, conization, etc.) without anterior or posterior wall prolapse were included in the control group. Biopsy material was obtained from the epithelium of the posterior wall of the vagina, including the fascia that fits the Ap point. Immunohistochemical staining with Protein Gene Product 9.5 and smooth muscle α-actin was performed in the pathology laboratory. The epithelial thickness measurement and smooth muscle density parameters obtained with these immunohistochemical stainings were compared between the two groups. The collected data were analyzed using the SPSS 23 package program. p values less than 0.05 were considered statistically significant. Results: In the control group, muscle thickness and the number of nerves per mm2 of fascia were statistically significantly higher than in the study group (p < 0.05). Conclusions: We found that smooth muscle tissue and the number of nerves per mm2 of fascia were decreased in posterior vaginal wall prolapse compared to the general population. Based on the correlation coefficients, age was the parameter that most affected the degree of prolapse, followed by parity, number of live births, and number of vaginal deliveries.

RESUMO

Objective: To compare the short-term results of classic single-layer uterine closure and double-layer purse-string uterine closure (Turan technique) techniques in cesarean section in terms of the incidence of ischiocele formation. Materials and Methods: This was a prospective randomized controlled trial study. Participants undergoing first-time cesarean delivery were randomized into two groups. Fifty-eight participants were included in the double-layered uterine closure group (study group), while 53 participants were randomized into the classical single-layered uterine closure group (control group). For comparison of isthmocele formation, transvaginal ultrasound examination was planned in all patients 6 weeks after surgery. The operation data,the formation of isthmocele, its dimensions and volume were recorded. Results: A total of 111 women were included in the study. The incidence of ischiocele at 6 weeks after birth was not significantly different between the groups (p=0.128). Isthmosel was detected in 20.8% of single-layer closures, and this rate was determined as 10.3% in the purse technique. In the Kerr incision made during surgery, the uterine incision size did not differ in either group, but the uterine incision length after suturing was significantly smaller in the purse technique compared with the other group (p<0.001). Conclusion: The incidence of ischiocele formation after cesarean section and the depth of the ischiocele was independent of the uterotomy closure technique.

RESUMO

AIM: To determine whether there was a significant difference between serum endocan levels of pregnant women with and without gestational diabetes mellitus (GDM). METHODS: A total of 90 pregnant women, 45 with gestational diabetes and 45 healthy pregnant women, between 24 and 28 gestational weeks, were included in this prospective case-control study. The pregnant women were screened for gestational diabetes using a two-step protocol. Serum endocan levels were measured using a commercially available enzyme-linked immunosorbent assay (ELISA) kit. A p-value of <0.05 was considered statistically significant. RESULTS: Serum endocan level was significantly higher in the GDM group than in healthy controls (168.46 ± 160.6 vs. 105.66 ± 26.52 pg/mL, respectively; p < 0.001). Serum endocan concentrations were positively correlated with the results of 50 g oral glucose challenge test (GCT) (p < 0.001). Receiver operating characteristic curve analysis showed that endocan with a cut-off point of 133.9 ng/dL indicated women with GDM with a sensitivity of 55.6% and specificity of 88.9% (area under the curve [AUC]: 0.737, 95% CI: 0.634-0.824). The overall differential performance of endocan according to the GDM groups was determined as 73.7% (p < 0.001). Maternal serum endocan level was positively correlated with fasting glucose, postprandial glucose, and glycated hemoglobin (HbA1c) (p < 0.001). CONCLUSIONS: Elevated endocan levels in gestational diabetes were correlated with fasting glucose, postprandial glucose, HbA1c, and oral glucose tolerance test (OGTT) results. Despite the low sensitivity of 55.6% and the high specificity of 88.9%, we found a high differential performance rate indicating that serum endocan levels were important for the pathophysiology of GDM and should be investigated for the possibility of being a novel marker in larger populations.

RESUMO

The study reported here aimed to develop and optimize the S-SNEDDS tablet of bosentan (BOS) and to investigate its pharmacokinetic and biodistribution properties. The BOS-loaded SNEDDS have been developed and characterized in a previous study. The BOS-loaded SNEDDS formulation was converted to S-SNEDDS using Neusilin® US2. The S-SNEDDS tablets were obtained using the direct compression technique, and in vitro dissolution, in vitro lipolysis, and ex-vivo permeability studies of the tablets were performed. The S-SNEDDS tablet and reference tablet (Tracleer®) were administered to male Wistar rats at 50 mg/kg dose by oral gavage in fasted and fed state conditions. The biodistribution of the S-SNEDDS tablet was investigated in Balb/c mice using fluorescent dye. The tablets were dispersed in distilled water before administration to animals. The relationship between in vitro dissolution data and in vivo plasma concentration was examined. The S-SNEDDS tablets showed 2.47, 7.49, 3.70, and 4.39 increases in the percentages of cumulative dissolution in FaSSIF, FeSSIF, FaSSIF-V2, and FeSSIF-V2, respectively, when compared to the reference, and increased the Cmax and AUC 2.65 and 1.28-fold and 4.73 and 2.37-fold in fasted and fed states, respectively, when compared to the reference. S-SNEDDS tablets also significantly reduced interindividual variability in both fasted and fed states (p < 0.05). The XenoLight™ DiR and VivoTag® 680XL labeled S-SNEDDS tablet formulation increased the real-time biodistribution in the body by factors of 2.4 and 3.4 and organ uptake and total emission increased by factors of 2.8 and 3.1, respectively. The IVIVR has been successfully established for S-SNEDDS tablets (R2 > 0.9). The present study confirms the potential of the S-SNEDDS tablet to enhance the in vitro and in vivo performance of BOS.

RESUMO

To search whether or not the severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) messenger ribonucleic acid (mRNA) vaccine affects the fertility of women at the 6th months by using AMH, which is an ovarian reserve test. Our study, designed as a prospective case-control study, included 104 women who presented to the GOP EAH obstetrics and gynecology outpatient clinic in January and February 2022. The study group included 74 women who presented to the outpatient clinic and planned to be vaccinated and 30 women who refused to be vaccinated as the control group. Anti-COVID-19 antibody levels in all participants were checked before participation in the study, and participants who were positive were excluded from the study. Blood was taken from the participants in both control and study groups to evaluate their AMH levels before the 2 doses of vaccination. After 2 doses of the vaccine, they were called for follow-up, and serological tests were performed to check whether they were positive for anti-COVID-19 antibodies. Participants in both groups were referred for follow-up after 6 months, samples were taken again for AMH, and the data were recorded. The mean age of the study group was 27.6 ±â€…5.3 years, and the mean age of the control group was 28.65 ±â€…5.25 years (P = .298). There was no statistically significant difference between the vaccinated and nonvaccinated groups in terms of AMH levels measured at the 6th month (P = .970). When the vaccinated group was compared in terms of AMH values at the first visit before vaccination and at the 6th month after vaccination, no statistically significant difference was found between them (p:0.127) mRNA vaccination to protect against SARS-CoV-2 does not adversely affect ovarian reserve, which is an indirect indicator of fertility. mRNA vaccines continue to be the most important method of protection against epidemics. Carefully and accurately informing women who are hesitant to get vaccinated is of great importance for the success of the fight against the epidemic.

RESUMO

Objective: To evaluate the effects of dydrogesterone treatment on first-trimester aneuploidy screening markers and nuchal translucency (NT) in women with threatened miscarriage. Materials and Methods: This study is an prospective case-control study. One hundred seven pregnant women who applied for the first-trimester screening test at 11-14th weeks of gestation were included in the study. The study group consisted of 53 pregnant women using oral dydrogesterone due to the threat of miscarriage for at least 2 weeks and without vaginal bleeding for the last 72 h at the time of enrollment. The control group was composed of 54 healty pregnant women. Fetal Crown-rump length (CRL), NT, pregnancy-associated plasma protein-A (PAP-A) level, and free beta-human chorionic gonadotropin (free B-hCG) levels of the patients were measured. Results: One hundred seven patients included in the study, 54 (50.46%) were in the control group, and 53 (49.54%) were in the study group using dydrogesterone. Age, body mass index, gravida, parity and abortion numbers, gestational weeks, and CRL values of the two groups were congruent. In the comparison-free B-hCG, PAPP-A and NT values of both groups, no statistically significant difference was found between the two groups in terms of first-trimester test results and NT (p<0.05). Conclusion: The use of dydrogesterone in first-trimester pregnancies does not affect first-trimester screening tests and nuchal translucency.

RESUMO

Background/aim: To evaluate whether there is a relationship between serum myosin-binding protein C (MyBP-C) levels measured in the first trimester and the timing of delivery, and, if a relationship is detected, the potential of this relationship in distinguishing between preterm and term labor. Materials and methods: This prospective case-control study was conducted with 701 pregnant women who applied to the Obstetrics Outpatient Clinic of Gaziosmanpasa Training and Research Hospital in the first trimester, between 11 and 14 gestational weeks. MyBP-C serum samples from the first trimester were stored under appropriate conditions until the time of delivery. Of these pregnant women, 628 completed the study. According to the delivery time, the pregnant women were divided into two groups, as those who delivered prematurely before 37 weeks and those who gave birth at term. The case group comprised 45 women who gave birth prematurely, while 583 women gave birth at term. A control group was formed with 45 pregnant women of the same age, who were selected by randomization using a simple random sampling method from the 583 pregnant women. The MyBP-C levels were measured and compared from the first-trimester serum materials of both groups. Results: The MyBP-C levels of the preterm delivery group were significantly higher than those of the term delivery control group (4.51 ± 1.69 vs. 3.09 ± 1.44 pg/mL, respectively; p < 0.001). Receiver operating characteristic (ROC) curve analysis showed that the MyBP-C levels in the first trimester with a cut-off value of 4.76 ng/dL indicated women with preterm delivery with a sensitivity of 42.22% and specificity of 95.56% (AUC: 0.734, 95% CI: 0.630-0.822). The overall differential diagnosis performance of the MyBP-C level for preterm delivery was determined as 73.4% (p < 0.001). The MyBP-C levels were found to be significantly higher both in the early preterm group compared with the late preterm group (p < 0.001), and in those with premature rupture of membranes (PROM) compared with those without (p < 0.001). Conclusion: The preterm delivery group exhibited high serum MyBP-C levels in the serum samples taken in the first trimester. First-trimester serum MyBP-C levels seem to be a simple and easy way to exclude preterm delivery risk in a significant manner. In addition, levels are significantly higher for early preterm compared with late preterm and early PROM compared with intact membranes.

RESUMO

Objective: Ceramide (CER) is a bioactive component of the mitochondrial membrane. In this study, we will investigate the clinical importance of serum CER (sCER) and follicular fluid CER (ffCER) levels in the lipid synthesis pathway and their effect on poor oocyte quality and in vitro fertilization (IVF) outcome. Materials and Methods: This cross-sectional, case-control study was conducted in the IVF unit of a maternity hospital in the capital of Turkey, Ankara. A total of 88 women undergoing their first IVF cycle were included in this study patients were divided into 2 groups according to current diagnostic criteria for their ovarian reserves. Baseline sCER levels, and ffCER concentrations retrieved on the oocyte pickup day were measured. Results: The mean age, body mass index, and infertility duration of the patients was similar between the groups (all p>0.05). There was also no significant difference in the clinical pregnancy rates (38.6% vs. 47.7%, p=0.127). sCER (15.6±6.5 vs. 23.5±8.9) and ffCER (82.5±34.3 vs. 116.4±46.5) levels were statistically significantly lower in the low ovarian reserve (LOR) group (both p<0.001). The performed receiver operating characteristic curve analysis revealed that sCER and ffCER levels could predict both LOR and pregnancy. Conclusion: This is the first study evaluating the sCER and ffCER levels of patients undergoing IVF treatment. CER may be used as an ovarian reserve markers and a biomarker capable of predicting IVF outcomes.

RESUMO

BACKGROUND: We aimed to investigate the levels of ADAMTS-1, which is secreted from the extracellular matrix during trophoblastic invasion in hyperemesis gravidarum (HEG). METHODS: In this cross-sectional study, we compared 45 HEG patients aged between 21 and 34 in terms of ADAMTS-1 levels with a control group consisting of 44 healthy pregnant women. The demographic characteristics and several laboratory parameters of the patients were recorded. Both groups were also compared in terms of ketonuria. We evaluated the correlation between ADAMTS-1 levels and ketonuria. RESULTS: The 2 groups were matched in terms of age, gestational age, gravidity, parity, and body mass index. Some inflammatory markers, such as neutrophil count, MPV, PDW, and PCT levels, were significantly higher in the HEG groups compared to the control group (all p < 0.05). However, mean MCV and serum TSH levels were statistically significantly lower in this group (both p < 0.001). ADAMTS-1 levels were 12.6 ± 1.4 ng/ml in the HEG group and 6.2 ± 1.6 ng/ml in the control group (p < 0.001). It was significantly and positively correlated with urine ketone, neutrophil count, and PDW, whereas negatively correlated with MCV and TSH value in the HEG group. ROC analysis showed that a threshold value of 11.275 ng/ml for ADAMTS-1 predicted HEG patients with a sensitivity of 60% and specificity of 95.5%. CONCLUSION: ADAMTS-1 serum levels are increased in HEG patients, and there is a positive correlation between ADAMTS-1 levels and ketonuria.

RESUMO

This study aimed to develop and optimize a self-nanoemulsifying drug delivery system (SNEDDS) of bosentan (BOS) to solve its poor oral bioavailability due to low water solubility. A pseudo-ternary phase diagram was created based on the solubility and emulsification studies. The major components of the formulation were selected as glyceryl monolinoleate (lipid), polyoxyl 40 hydrogenated castor oil (surfactant), and caprylocaproyl polyoxyl-8 glycerides (co-surfactant). The composition of BOS-SNEDDS was optimized using the Box-Behnken design (BBD) and then was characterized for various physicochemical properties. The in vitro dissolution, in vitro lipolysis, and ex-vivo permeability studies were performed and compared to SNEDDS and reference tablets. The fasted and fed state bioavailability of BOS-loaded SNEDDS was evaluated in Wistar rats (n = 6) compared to the reference. The prepared SNEDDS were thermodynamically stable with a droplet size of 17.11 nm, a polydispersity index of 0.180, and an emulsification time of <1 min. The BOS-loaded SNEDDS showed 3.0, 7.97, 4.23, and 4.94-fold increases in the percentages of cumulative dissolution compared to reference tablets in FaSSIF, FeSSIF, FaSSIF-V2, and FeSSIF-V2, respectively. The permeation study showed that the SNEDDS increased the drug permeation by 3.36, 19.2, 16.4, and 16.6-fold in FaSSIF, FeSSIF, FaSSIF-V2, and FeSSIF-V2, respectively. The enhancement of in vitro dissolution, in vitro lipolysis, and ex-vivo permeability was found significant (p < 0.05). SNEDDS was increased the Cmax and AUC 1.67 and 2.12-fold and 5.15 and 1.84-fold in fasted and fed state compared to the reference, respectively. The in vitro-in vivo relationship has been successfully performed for SNEDDS. These results indicated that the SNEDDS formulation could be a promising delivery system that enhances the absorption and oral bioavailability of BOS.

RESUMO

OBJECTIVE: To elucidate predictors of adverse maternal and perinatal outcomes in refugees emigrating from an active conflict region (Syria). MATERIALS AND METHODS: This study included Syrian pregnant women who gave birth in Etlik Zübeyde Hanim Training and Research Hospital between 2013 and 2016. Adverse perinatal outcomes were defined as preterm labor, premature rupture of membranes, early membrane rupture, intrauterine growth retardation, hypertension, perinatal excites, and erythrocyte-transfused cases. Factors associated with those adverse outcomes were assessed using multiple logistic regression analysis. RESULTS: Having an active smoking habit [odds ratio (OR): 2.647, 95% confidence interval (CI): 1.767-3.965; p<0.001], obesity (OR: 2.272, 95% CI: 1.396-3.699; p=0.001), and adolescent age (OR: 1.732, 95% CI: 1.204-2.491; p=0.003) were found to be the most important predictors of adverse maternal and perinatal outcomes. Eighty of 129 (62%) smokers, 45 of 81 (55.65%) obese individuals, and 91 of 169 adolescents (53.8%) had adverse maternal and perinatal outcomes. CONCLUSION: Prevention strategies for obesity, smoking, and adolescent pregnancies should be implemented primarily to reduce maternal and antenatal adverse outcomes. Pregnant women with these risk factors in a refugee community emigrating from a conflict-zone nation should be followed up closely.

RESUMO

SUMMARY: This study aimed to investigate the toxic effects of cigarette smoke exposure on lung and the protective role of Omega 3 and Vitamin D against these toxic effects biochemically and histologically. 28 pregnant Wistar Albino rats were divided into four groups. The first group was control group; the second group was exposed to smoke of 10 cigarette by puff device 2 hours/day after pregnancy; the third group was exposed to cigarette smoke together with Omega 3 (0.5 mg/kg/day) and the fourth group was exposed to cigarette smoke together with vitamin D (42 microgram/kg/day). Finally, lung tissue sections of the newborn rats were stained with Hemotoxilen eosine and Masson tricromite. Malondialdehyde (MDA) and Fluorescent Oxidation Products (FOU) levels were measured. Fetal weights and the number of fetuses were significantly lower in the group received only cigarette smoke (both p<0.001). Histopathologically, pulmonary volume, number of developed alveols and parenchyma elasticity decreased significantly, meanwhile interstitial tissue increased, elastin and collagen did not develop adequately. Histopathologic changes significantly decreased in the group given Omega 3 and Vitamin D. Statistically, MDA and FOU levels were found to be higher in the group exposed to cigarette smoke compared to the control group, and MDA and FOU levels were lower in the group given Omega 3 along with cigarette smoke (p<0.001). Cigarette smoke caused histologically significant damage to fetal lung tissue, oxidative stress and increased MDA and FOU levels. This damage was significantly reduced with Omega 3 and Vitamine D supplementation. Omega 3 is an important antioxidant; vitamin D has no significant antioxidant effect.


RESUMEN: Este estudio tuvo como objetivo investigar los efectos tóxicos de la exposición al humo de cigarrillo en el pulmón, y el papel protector de Omega 3 y la Vitamina D contra esos efectos. 28 ratas Wistar albino preñadas fueron separadas en cuatro grupos. El primer grupo grupo control; el segundo grupo estuvo expuesto al humo de 10 cigarrillos por dispositivo de inhalación 2 horas / día después de la preñez; el tercer grupo se expuso al humo del cigarrillo junto con Omega 3 (0,5 mg / kg / día) y el cuarto grupo se expuso al humo del cigarrillo junto con vitamina D (42 microgramos / kg / día). Secciones de tejido pulmonar de las ratas recién nacidas se tiñeron con Hematoxilina Eosina y tricrómico de Masson. Se midieron los niveles de malondialdehído (MDA) y productos de oxidación fluorescente (POF). Los pesos fetales y el número de fetos fueron significativamente más bajos en el grupo que recibió solamente humo de cigarrillo (ambos p <0,001). Histopatológicamente, el volumen pulmonar, el número de alveolos desarrollados y la elasticidad del parénquima disminuyeron significativamente; mientras que el tejido intersticial aumentó y la elastina y el colágeno no se desarrollaron adecuadamente. Los cambios histopatológicos disminuyeron significativamente en el grupo que recibió Omega 3 y Vitamina D. Estadísticamente, se encontró que los niveles de MDA y POF eran más altos en el grupo expuesto al humo de cigarrillo en comparación con el grupo control, además los niveles de MDA y POF fueron más bajos en el grupo que recibió Omega 3 junto con el humo del cigarrillo (p <0,001). El humo del cigarrillo causó daños histológicamente significativos en el tejido pulmonar fetal, el estrés oxidativo y el aumento de los niveles de MDA y FOU. Este daño se redujo significativamente con los suplementos de Omega 3 y Vitamina D. El omega 3 es un importante antioxidante; la vitamina D no tiene ningún efecto antioxidante significativo.

RESUMO

OBJECTIVE: The association between serum betatrophin levels and hyperemesis gravidarum (HEG) remains unknown. The aim of this study was to determine and understand the alterations in serum betatrophin levels in pregnancies complicated by HEG compared with unaffected normal pregnancies. STUDY DESIGN: A cohort study was carried out to evaluate serum betatrophin levels in patients with HEG. Serum betatrophin concentrations were measured with other metabolic markers for lipids and glucose metabolism in 40 singleton pregnancies affected by HEG and 40 gestational age- and body mass index-matched controls. RESULTS: The serum betatrophin concentrations were significantly higher in pregnant women with HEG than in the controls (1000 [600-1100] vs. 900 [500-1000] pg/ml, p = 0.003). The serum total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) levels were significantly higher in patients with HEG than in the healthy counterparts at the first trimester of pregnancy (158.5 ±â€¯29.4 vs. 143.8 ±â€¯29.7 mg/dl and 47.3 ±â€¯14.2 vs. 40.1 ±â€¯8.6 mg/dl, p = 0.031 and p = 0.007, respectively). Receiver operating characteristic (ROC) analyses demonstrated that the area under the curve (AUC) indicative of the betatrophin value for discriminating HEG patients was 0.690 (95% CI: 0.574-0.806, p = 0.003). The optimal cutoff value was 976 pg/ml with a sensitivity of 50% (95% CI: 33.80-66.20%) and a specificity of 82.5% (95% CI: 67.22-92.66%). We also found a positive correlation between betatrophin levels and HDL-C (r = 0.311; p = 0.005). Logistic regression analyses demonstrated that increased levels of betatrophin and HDL-C were risk factors for HEG with odds ratios (95% confidence interval) of 4.884 (1.589-15.009) and 5.346 (1.044-27.366), respectively. CONCLUSION: We conclude that serum betatrophin concentrations were increased in pregnancies affected by HEG. Furthermore, HDL-C levels seem to be associated with alterations in serum betatrophin levels.

RESUMO

INTRODUCTION: This study aimed to investigate the influence of obesity on pregnancy complications and neonatal outcomes in diabetic and nondiabetic women. MATERIALS AND METHODS: This retrospective case control study was conducted on 1193 pregnant women and their neonates at a tertiary level maternity hospital between March 2007 and 2011. The pregnant women were classified into 2 groups according to the presence of diabetes mellitus. Six hundred and seven patients with gestational diabetes or pregestational diabetes formed the diabetic group (study group) and 586 patients were in the nondiabetic group (control group). Demographic characteristics, body mass index, gestational weight gain, obstetric history, smoking status, type of delivery, gestational ages, pregnancy complications, neonatal outcomes were recorded for each patient. Multivariable logistic regression analysis was performed to evaluate the effect of obesity and diabetes on the pregnancy complications and neonatal outcomes. RESULTS: The mean age and pre-pregnancy body mass indices of women with diabetes mellitus were significantly higher than the control group's (p < 0.001). Gestational weight gain and number of smokers were similar among the groups. Multiparity and obesity were more prevalent in the diabetic group compared to controls (both p < 0.001). Although gestational age at birth was earlier in the diabetic group, birth weights were higher in this group than in the control group (both p < 0.001). Cesarean delivery rates, the incidence of macrosomia, and neonatal intensive care unit admission rates were significantly higher in the diabetes group both with normal and increased body mass index (all p < 0.001). However, adverse pregnancy outcomes were comparable between the groups (p = 0.279). Multivariable logistic regression analysis showed that obesity is a significant risk factor for pregnancy complications (OR = 1.772 [95% CI, 1.283 - 2.449], p = 0.001) but not for adverse neonatal outcomes (OR = 1.068 [95% CI, 0.683 - 1.669], p = 0.773). CONCLUSION: While obesity increases risk of developing a pregnancy complication, diabetes worsens neonatal outcomes.

RESUMO

OBJECTIVES: Multiple pregnancies are known to be associated with adverse maternal and perinatal complications. How-ever, data regarding the outcomes of spontaneously reduced twin pregnancies are limited. In the current study we aimed to evaluate the consequences of the vanishing twin syndrome (VTS) in dichorionic diamniotic twin pregnancies for both mother and baby in our perinatal center. MATERIAL AND METHODS: A total of 711 pregnancies were included into the study. 51 cases of vanishing twin syndrome constituted Group 1, 235 cases of normal twins constituted Group 2, and 425 singleton pregnancies formed Group 3. The pregnancies that had multifetal reduction and monochorionic twinning were excluded from both study group and twin control group. The collected data were as follows: age, gravidity, parity, gestational week at birth, delivery route, birth weight, obstetric complications, and maternal and perinatal outcomes. RESULTS: No significant difference was observed between the groups regarding mean maternal age (p > 0.05). Mean birth weight, gestational age at birth and preterm birth ratio were significantly lower in the Group 2 when compared with Group 1 and Group 3 (all p < 0.001). Adverse perinatal outcomes including very low birth weight (VLBV) and low Apgar scores were more common in Group 1 (p < 0.05), but no significant difference was found between the groups in terms of neona-tal intensive care unit admission and perinatal mortality ratios (p > 0.05). Obstetric complications such as preeclampsia, gestational diabetes and intrauterine growth restriction were significantly higher in Group 2 than in Group 1 and Group 3 (all p < 0.05). However, severe maternal morbidities were similar among three groups (p = 0.141). CONCLUSIONS: VTS is seems to be associated with VLBV and low Apgar scores. However, the incidence of severe maternal and perinatal morbidity and mortality in pregnancies with VTS is similar to other pregnancies.
