The effect of abdominal massage and stretching exercise on pain and dysmenorrhea symptoms in female university students: A single-blind randomized-controlled clinical trial.

In this study the researchers aimed to determine the effect of abdominal massage and stretching exercises on the severity of pain, dysmenorrhea symptoms and menstrual blood lost in university students. In this single-blind randomized controlled clinical trial 63 university students were included. Participants were randomly assigned into massage group, exercise and control groups. Our findings showed that the 2nd cycle scores related to abdominal-back pain and fatigue in the massage group and 2nd cycle scores related to mood change in the exercise group were significantly lower than those of the massage and control groups. However, there was no difference between groups in terms of the Visual Analogue Scale scores and blood lost. Our evidence indicates that massage was effective on abdominal-back pain and weakness, and exercise was effective on mood change.

The rate of oocytes with granular cytoplasm is higher in women with endometrioma in ICSI cycles.

The purpose of this study was to investigate the impact of endometrioma on oocyte morphology and fertility outcome in intracytoplasmic sperm injection (ICSI)cycles. The study material was obtained from 114 ICSI cycles of infertile women aged between 20 and 38 years with ovarian endometriomas and unexplained infertility. In total, 644 mature oocytes were included in the analysis. The rates of specific oocyte morphological abnormalities were similar between the two groups however the central granulation rate was significantly higher in the group with endometrioma (p < .05). Fertilisation rate were not significantly different between the groups (p ≥ .05) however the numbers of metaphase 2 (MII) oocytes and embryos were lower in the endometrioma group (p ≤ .05). Endometrioma was associated with a higher rate of oocytes with granular cytoplasm, despite the fertilisation rate the numbers of the MII oocytes and embryo were affected.IMPACT STATEMENTWhat is already known on this subject? The association between endometrioma and infertility is a well-known condition, but the possible mechanisms of the effects of endometrioma on women's fertility is still debated and controversial. There is limited data on the effect of endometrioma on oocyte morphology. Low oocyte quality and lower fertilisation rates might be the main cause of adverse pregnancy outcomes during in vitro fertilisation/intracytoplasmic sperm injection cycles.What do the results of this study add? Endometrioma was associated with a higher rate of oocytes with granular cytoplasm, and lower metaphase 2 oocytes and embryos.What are the implications of these findings for clinical practice and/or further research? Future studies using further oocyte quality assessment methods and prospective observational studies including live-birth rate should be designed to better understand how endometrioma affects fertility outcomes.

The effect of gestational diabetes on the expression of mitochondrial fusion proteins in placental tissue.

INTRODUCTION: Gestational diabetes mellitus (GDM) poses a risk factor for fetal mortality and morbidity by directly affecting the placenta and fetus. Mitochondria are dynamic organelles that play a key role in energy production and conversion in placental tissue. Mitochondrial fusion and fission proteins are important in terms of providing mitochondrial dynamics, the adaptation of the cell to different conditions, and maintaining the metabolic stability of the cells. Although GDM shares many features with Type 2 diabetes mellitus (T2DM), different effects of these conditions on the mother and the child suggest that GDM may have specific pathological effects on placental cells. The aim of this study is to investigate the expression of mitochondrial dynamics, and mitochondrial protein folding markers in placentas from GDM patients and women with pre-existing diabetes mellitus. METHODS: Placentas were properly collected from women, who had pre-existing diabetes (Pre-DM), from women with gestational diabetes mellitus (GDM) and from healthy (non-diabetic) pregnant women. Levels of mitochondrial fusion markers were determined in these placentas by real time quantitative PCR and Western blot experiments. RESULTS: mRNA expressions and protein levels of mitochondrial fusion markers, mitofusin 1, mitofusin 2 (MFN1 and MFN2) and optical atrophy 1 (OPA1) proteins were found to be significantly lower in both Pre-DM placentas and those with GDM compared to healthy (non-diabetic) control group. Likewise, proteins involved in mitochondrial protein folding were also found to be significantly reduced compared to control group. DISCUSSION: Diabetes during pregnancy leads to processes that correlate with mitochondria dysfunction in placenta. Our results showed that mitochondrial fusion markers significantly decrease in placental tissue of women with GDM, compared to the healthy non-diabetic women. The decrease in mitochondrial fusion markers was more severe during GDM compared to the Pre-DM. Our results suggest that there may be differences in the pathophysiology of these conditions.

Predictive value of serum and follicular fluid chemerin concentrations during assisted reproductive cycles in women with polycystic ovary syndrome.

AIMS: To evaluate the effect of serum and follicular fluid (ff) Chemerin levels on Assisted Reproductive Technology (ART) outcomes in lean patients with PCOS. MATERIALS AND METHODS: The study included 76 infertile reproductive aged women, between 21-35 years who underwent intracytoplasmic sperm injection (ICSI) procedure. Serum and ff Chemerin levels were evaluated. Fertilization and clinical pregnancy rate were compared between the groups. RESULTS: Serum (13.32 ng/ml versus 29.82 ng/ml) and ff chemerin (35.90 ng/ml versus 87.60 ng/ml) levels were significantly higher in lean PCOS patients compared to controls (p < .01). Serum (24.5 ng/ml versus 18.4 ng/ml) and ff chemerin (71.7 ng/ml versus 52.8 ng/ml) levels were higher in subjects without clinical pregnancy compared to the subjects with clinical pregnancy (p < .05). A cutoff value of 36.2 ng/ml in the ff chemerin level was found to estimate clinical pregnancy with 83% sensitivity and 52% specificity (Area under the curve 0.66; 95% confidence interval, 0.53-0.79). A cutoff value of 12.7 ng/ml in the serum chemerin level was found to estimate clinical pregnancy with 91% sensitivity and 49% specificity (Area under the curve 0.65; 95% confidence interval, 0.52-0.78). Clinical pregnancy rates were significantly higher in group with lower serum chemerin levels (80.0% versus 30.4%, p < .001). High serum chemerin levels are associated with failure of assisted reproduction [OR:0.1(95% CI, 0.03-0.4, p < .001)]. CONCLUSIONS: PCOS is associated with higher serum and ff chemerin levels and high serum chemerin level is a risk factor for failed ART cycle.

Association between circulating neuregulin 4 levels and metabolic, aterogenic, and AMH profile of polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a metabolic disorder associated with obesity and energy metabolic system disturbances in adipose tissue. Neuregulin 4 (NRG4), which is secreted by adipose tissue, regulates energy metabolism. In the present study, we aimed to evaluate the association between serum NRG4 levels in obese and normal weight PCOS patients. This cross-sectional study was conducted at a tertiary hospital in Turkey from April to August 2017. We included 148 women who were divided into four groups as follows: 40 normal weight and 39 obese PCOS women diagnosed according to the Rotterdam criteria as well as 38 normal weight and 31 obese, age-matched, non-hyperandrogenemic women with a regular menstrual cycle (controls). Levels of serum NRG4, anti-Müllerian hormone (AMH), fasting blood glucose (FBG), insulin, and high-sensitivity C-reactive protein (hs-CRP); lipid and hormone profiles; insulin resistance indices [homeostasis model assessment of insulin resistance (HOMA-IR)];and anthropometric parameters were evaluated. Serum NRG4 levels were elevated in the normal weight PCOS group than in the control group. Moreover, serum NRG4 levels were higher in the obese PCOS group than in the normal weight PCOS and obese control groups (p < .01). Serum NRG4 levels were positively correlated with body mass index (BMI); waist/hip ratio; HOMA-IR; and levels of triglycerides, hs-CRP, FBG, insulin, AMH, and dehydroepiandrosterone sulphate. Multiple regression analyses revealed that serum NRG4 levels were independently associated with BMI. Obesity appears to be the most influential factor for NRG4 secretion in PCOS patients. Management of obesity may be a key factor for resolving PCOS-related metabolic abnormalities and fertility problems. Impact Sstatement What is already known on this subject? PCOS is a dynamic syndrome with different clinical and metabolic features during the reproductive age. PCOS is associated with various metabolic abnormalities, such as insulin resistance (IR), glucose intolerance, dyslipidemia, and obesity (particularly visceral obesity) as well as long-term complications, such as type 2 diabetes and cardiovascular diseases. Neuregulin 4 (NRG4), which is secreted by adipose tissue, regulates energy metabolism. What do the results of this study add? To the best of our knowledge, this was the first study investigating NRG4 levels in PCOS patients with different BMIs. Obesity appears to be the most influential factor for NRG4 secretion in these patients. Managing obesity may be a key factor for resolving PCOS-related metabolic abnormalities. What are the implications of these findings for clinical practice and/or further research? Further research in PCOS is warranted to ameliorate obesity, and our study can provide basis for future studies investigating NRG4 levels in PCOS patients with different phenotypes as well as studies of gene polymorphisms, AMH, and infertility and can contribute to the elucidation of problems related to the pathophysiology of PCOS.

Effect of vaginal washing before intravaginal dinoprostone insertion for labor induction: A randomized clinical trial.

AIM: Prostaglandins have a dual action of cervical ripening and induction of uterine contraction. This study was designed to compare the effectiveness of vaginal washing just before insertion of intravaginal dinoprostone. METHODS: A randomized controlled trial was conducted at the Zeynep Kamil Women and Children's Health Training and Research Hospital. One hundred and ninety-one women with singleton, term pregnancy who underwent labor induction were randomly assigned to two groups: Group 1 consisted of 95 pregnant women with vaginal washing before intravaginal dinoprostone (Propess system for slow release system of 10 mg of dinoprostone) insertion (study group), and 96 pregnant women constituted the control group who did not undergo vaginal washing before intravaginal dinoprostone insertion. A parallel randomized controlled trial was conducted with an allocation ratio of 1:1 to compare the effectiveness of vaginal washing before intravaginal dinoprostone insertion. RESULTS: The groups had similar mean age, body mass index, gestational age, gravidity, parity and Bishop score before agent insertion (P > 0.05). Duration of dinoprostone kept intravaginally, duration from the beginning of dinoprostone insert vaginally to the active phase of labor and duration from the time of intravaginal dinoprostone insertion to delivery were significantly longer in the control group (P < 0.05). Uterine hyperstimulation rate was significantly higher in study group compared to control group (P < 0.05). Meconium passage, fetal infection and neonatal intensive care unit admission were significantly higher in the control group (P < 0.05). CONCLUSION: Vaginal washing before intravaginal dinoprostone insertion may increase Prostaglandin E2 bioavailability as we found shorter duration and better outcome of labor induction in the present study.

Second trimester maternal serum-amniotic fluid nitric oxide and vascular endothelial growth factor levels in relation to uterine artery Doppler indices in pregnancies with normal outcome.

The aim of the present study was to explore the possible relations of maternal serum and amniotic fluid nitric oxide (NO) and of vascular endothelial growth factor A (VEGF-A) concentrations with uterine artery Doppler indices (UtADs) in a healthy second trimester obstetric population. In this regard, the levels of NO and VEGF-A were measured in maternal sera and the amniotic fluid samples were in 36 subjects who were in their early second trimester of pregnancy. The mean levels for VEGF-A were 110.3 ± 31.5 pg/ml in maternal serum and 149.6 ± 31.3 pg/ml in amniotic fluid. Mean levels for NO were 5.7 ± 4.7 µmol in maternal serum and 12.9 ± 3.4 µmol in amniotic fluid. UtADs were measured concurrently with the sample collections. The mean value for uterine artery pulsatility index (PI) was 1.3 ± 0.4. The measurements were then analysed for possible correlations, whereby no correlation was found between UtAD and maternal serum levels of either molecule (p = .828 and p = .662 for VEGF-A and NO, respectively). However, a positive correlation was found between the NO levels in the amniotic fluid compartment and UtAD (r = 0.432, p = .009 for PI). Therefore, a correlation of UtAD with amniotic fluid NO can be expected in pregnancies with a normal outcome. Impact Statement What is already known on this subject? Nitric oxide (NO) and vascular endothelial growth factor A (VEGF-A) are important vasoactive molecules that play significant roles in early angiogenesis and placentation. What the results of this study add? There is a positive correlation between the amniotic fluid NO levels and the uterine artery Doppler indices (UtADs) in the second trimester of pregnancies with normal outcomes. What the implications are of these findings for clinical practice and/or future research? A correlation between amniotic fluid NO levels and UtAD may indicate a normal trophoblastic invasion. Disturbance of this balance may be expected in certain adverse pregnancy outcomes. Additional studies are needed to further explore the molecular signs of early abnormal placentation and their clinical reflection.

Prospective Randomized Trial Comparing Embryo Transfers of Cases with and without Catheter Rotation during Its Withdrawal.

OBJECTIVE: To compare embryo transfer (ET) technique based on catheter rotation during its withdrawal in cases with unexplained infertility in a prospective, randomized trial (NCT03097042). METHODS: Two hundred intracytoplasmic sperm injection (ICSI) patients undergoing ET with cleaving or blastocyst-stage fresh embryos were randomized into 2 groups: cases with (n = 100), and without (n = 100) catheter rotation during its withdrawal. Groups were matched for age and some clinical parameters. A soft catheter was used to transfer a single embryo with catheter rotation during its withdrawal in the study group and without rotation in the control. The use of a stiff catheter or tenaculum was not needed in any case. Groups were compared in terms of cycle characteristics and clinical pregnancy rates. RESULTS: Pregnancy rate was significantly higher in the study group (41 vs. 26%, p = 0.04). Clinical pregnancy rate was also significantly higher in the study group (39 vs. 25%, OR 1.9 [1.1-3.5], p = 0.05). On the other hand, the ongoing pregnancy rate was similar between the 2 groups (33 vs. 23%, p = 0.2). CONCLUSION: Catheter rotation during its withdrawal may be associated with increased pregnancy and clinical pregnancy rates; however, the difference in ongoing pregnancy rates did not reach statistical significance.

Serum procalcitonin levels together with clinical features and inflammatory markers in women with tubo-ovarian abscess for discriminating requirements for surgery for full recovery.

Tubo-ovarian abscess (TOA) coexists in 15% of cases with pelvic inflammatory disease. Medical treatment is the first line of approach in women with TOA, however, 25% of cases fail to respond to antibiotics, therefore, these cases need to undergo surgical intervention. We aimed to determine factors leading to failure of medical treatment in women diagnosed with TOA. According to our results among 144 women, 27 cases required surgical intervention for full recovery. None of the demographic, sonographic or laboratory findings, including procalcitonin level, had significant predictive value for the failure of medical treatment in women with TOA. Impact statement What is already known on this subject? Tubo-ovarian abscess (TOA) coexists in 15% of cases with pelvic inflammatory disease. Medical treatment is the first line approach in women with TOA, however, 25% of cases fail to respond to antibiotics, therefore, these cases need to undergo surgical intervention. Several risk factors have been evaluated in order to predict the failure of medical treatment. What do the results of this study add? None of the variables, including age, parity, mass diameter, serum CRP, procalcitonin levels and sedimentation rate had significant value for predicting TOA cases that required surgical intervention for full recovery. What are the implications of these findings for clinical practice and/or further research? In clinical practice, identification of risk factors leading to the failure of medical treatment helps clinicians to inform patients and help surgeons predict those who need surgical intervention.

Clinical significance of neuregulin 4 (NRG4) in gestational diabetes mellitus.

OBJECTIVE: Gestational diabetes mellitus (GDM) is defined as glucose intolerance detected during pregnancy. GDM is increasing worldwide and is associated with adverse maternal and fetal outcomes. Neuregulin 4 (NGR4) is epidermal growth factor like signaling molecule. It plays an important role in cell to cell communication furthermore recent studies indicate that NRG4 may work as a novel adipokine with a possible role in maintaining energy and metabolic homeostasis. The aim of the present study was to assess serum NRG4 levels along with several metabolic parameters in patients diagnosed with gestational diabetic mellitus. MATERIALS AND METHODS: In this prospective cross-sectional study, the study group was composed of 63 women with GDM and 64 healthy pregnant women matched for age, body mass index (BMI) and gestational age. Blood samples were collected at the 24-28th gestational weeks. Serum NRG4, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides, glucose levels during 75-gr OGTT, fasting insulin, glycosylated hemoglobin A1c (HbA1c), alanine aminotransferase (ALT) and creatinine levels were measured. Homeostasis model assessment of insulin resistance (HOMA-IR) values were calculated. RESULTS: Serum NRG4 values were significantly elevated in the GDM group compared to the control group (p < .001). Multivariate linear regression analyzes revealed that BMI (ß = 0.910, p < .001), glucose 2-h OGTT (ß = 0.866, p < .001) and HOMA-IR (ß = 0.222, p < .001) independently and positively predicted NRG4 levels. CONCLUSIONS: Serum NRG4 levels were associated with metabolic parameters of GDM. The present study can be considered to be a guide for future studies to clarify the pathophysiology of NGR4 in GDM patients.

The effect of labour pain in caesarean delivery on neonatal and maternal outcomes in a term low-risk obstetric population.

Planned caesarean delivery (CD) frequency is increasing in many countries, and elective CD accounts for 50% of preventable causes of neonatal respiratory morbidity. The clearing of fluid in the lungs is important for the establishment of normal gas exchange with inspired air. A defect in this clearance can result in respiratory problems in neonate, but on the other hand patients waiting for the onset of spontaneous labour pain, the increase in emergency CD, together with severe mortality and morbidity are causes of concern and cause anxiety and distrust of obstetricians. In the current study, it was observed that foetal respiratory morbidity was reduced in the group with labour pain. The caesarean applied after the onset of labour pain could be a reason for the significant increase in foetal cord cortisol values in term low-risk neonates. A major advantage of this study was the inclusion of a low-risk patient group, and the increase in foetal cortisol secondary to pain in term neonates was shown objectively. Impact statement What is already known on this subject: The timing of CD is reported to be critical for neonatal morbidity, and elective CD accounts for 50% of preventable causes of neonatal respiratory morbidity. The clearing of fluid in the lungs is important for the establishment of normal gas exchange with inspired air. Cortisol secretion from the foetal adrenal gland is stimulated by stress. What do the results of this study add: Labour pain-related stress in the foetus might be a cause for elevated physiological cortisol, and secondary to that, lower respiratory morbidity. Caesarean delivery commenced after the onset of labour pain could be a reason for the significant increase in foetal cord cortisol values in term neonates. A major advantage of this study was the inclusion of a low-risk patient group, and the increase in foetal cortisol secondary to pain in term neonates was shown objectively. What are the implications of these findings for clinical practice and/or further research: Although it would seem to be rational to perform a caesarean section after the onset of labour pain in cases with a planned caesarean and a history of C-section delivery, with respect to maternal complications, especially in those with a history of more than one caesarean or those who have started active labour; there is a need for further prospective studies.

Which factors are associated with the recurrence of endometrioma after cystectomy?

Endometrioma is the most common form of endometriosis and is a sign of wide-spread disease in symptomatic patients. Medical treatment options can be successful in endometrioma smaller than 1 cm, but ineffective for growing and symptomatic endometriomas. Conservative surgical interventions that preserve fertility, such as laparoscopic removal or destruction of endometriotic tissue or aspiration of cystic content are typically used to treat the condition. One of the most frustrating aspects of endometrioma treatment is disease recurrence. The underlying mechanisms explaining recurrence are uncertain. Several risk factors have been evaluated in order to predict recurrence after cystectomy. In looking at the results overall, our study can conclude that the presence of greater cyst dimension, higher CA-125 level, presence of preoperative symptoms of non-cyclic pelvic pain, dysmenorrhoea and adhesion extension may be associated with recurrent endometrioma. In clinical practice, identification of risk factors for recurrence helps clinicians to inform patients. Impact statement What is already known on this subject: Endometrioma is the most common form of endometriosis and is a sign of wide-spread disease in symptomatic patients. One of the most frustrating aspects of endometrioma treatment is disease recurrence. Several risk factors have been evaluated in order to predict recurrence after cystectomy. However, the risk factors have not been precisely defined. What the results of this study add: This study aimed to investigate the contribution of possible risk factors to the recurrence of endometrioma after laparoscopic surgery. In looking at the results overall, our study can conclude that the presence of greater cyst dimension, higher CA-125 level, adhesion extension, presence of preoperative symptoms of non-cyclic pelvic pain and dysmenorrhoea may be associated with recurrent endometrioma. What the implications of these findings are for clinical practice and/or further research: In clinical practice, identification of risk factors for recurrence helps clinicians to inform patients. Detection of preoperative risk factors would be helpful in counselling patients on their future prognosis. This may also increase treatment success by providing accurate preoperative treatment planning and by assisting the scheduling of postoperative follow-ups.

Premenstrual Syndrome Is Associated With a Higher Frequency of Female Sexual Difficulty and Sexual Distress.

Few prospective studies have evaluated the impact of premenstrual symptoms (PMS) on female sexual function and sexuality-related distress. The purpose of the present study was therefore to find out risk factors of PMS for  female sexual function and sexuality-related personal distress. This prospective cohort study was conducted at the Süleymaniye Women and Children's Health Training and Research Hospital in Istanbul, Turkey, between February 2014 and March 2016. The study group consisted of women admitted to the general gynecology outpatient clinic aged 18 to 40 years who met the inclusion criteria. The American College of Obstetricians and Gynecologists criteria were used for the initial diagnosis of PMS and the participants were allocated to PMS(+) and PMS(-) groups (healthy subjects). All participants completed the Beck Depression Inventory to exclude those at risk for depression. The patients with an initial diagnosis of PMS then completed the PMS Daily Record of Severity of Problems form prospectively for two consecutive menstrual cycles to confirm PMS diagnosis. Lastly, both sexual function and sexual distress of eligible PMS(+) (n = 143) and PMS(-) (n = 143) participants were assessed with both the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale-Revised (FSDS-R). According to the FSFI cutoff value, 77.6% of patients in the PMS(+) group and 27.3% of patients in the PMS(-) group had sexual concerns (p < 0.05). The sexuality-related personal distress rate was 51.7% in the PMS(+) group and 24.5% in the PMS(-) group (p < 0.05). Overall, 51.7% of the PMS(+) and 24.5% of the PMS(-) group were recognized as having sexual difficulties based on the presence of sexual distress and the low FSFI scores (p < 0.05). We concluded that women with PMS are likely to have sexual difficulties and a higher level of sexual distress, emphasizing the importance of the sexual aspects of PMS in clinical practice.

Association between maternal circulating 25 hydroxyvitamin D concentration and placental volume in the first trimester.

OBJECTIVES: We aimed to assess placental volume and placental mean gray value in vitamin D deficiency and healthy placentas in the first trimester of pregnancy using three-dimensional (3D) ultrasonography (USG) and Virtual Organ Computer-aided Analysis (VOCAL). METHODS: This prospective cross sectional study comprised 274 patients, divided into two groups according to the presence or absence of vitamin D deficiency (<20 ng/ml deficient, n = 153, >20 ng/ml not deficient, n= 121) in the first trimester of pregnancy. Placental volume and placental volumetric mean gray values were evaluated. Placental volume (cm3) was analyzed using the VOCAL imaging program and a 3D histogram was used to calculate the volumetric mean gray value (%). RESULTS: Placental volume was significantly less in the vitamin D deficiency group (p = 0.017) Volumetric mean gray value of the placenta was significantly higher in the vitamin D deficiency group (p= 0.003). Maternal serum PAPP-A (MoM) and f-ß Hcg (MoM) were significantly lower in the vitamin D deficiency group (p= 0.008, p = 0.003, respectively). In linear regression analyses, serum vitamin D concentration was significantly associated with the plasental volume (ß = 0.16; p = 0.01). CONCLUSION: Placental configuration and development were associated with vitamin D even in the first trimester of pregnancy. To ensure healthy pregnancy outcomes, vitamin D screening applied in the early stages of pregnancy or even before pregnancy.

Mycophenolate mofetil attenuates uterine ischaemia/reperfusion injury in a rat model.

This study evaluated the effect of mycophenolate mofetil (MMF) on uterine tissue preservation following ischaemia/reperfusion (I/R) injury. Uterine I/R injury was induced in rats by clamping the lower abdominal aorta and ovarian arteries for 30 min. Group I/R + V (n = 7) received vehicle alone while Group I/R + M (n = 7) received 20 mg/kg/day MMF. Control groups underwent sham surgery and received vehicle (Group C) or 20 mg/kg/day MMF (Group M) (n = 7 for both). Four hours after detorsion, uterine tissue 8-hydroxy-2'-deoxyguanosine (8-OHdG), glutathione, malondialdehyde (MDA), myeloperoxidase (MPO), superoxide dismutase (SOD) and serum ischaemia modified albumin (IMA) concentrations were measured. Histopathological analyses were performed. The I/R + M group showed significant reduction in serum IMA and uterine tissue 8-OHdG, MDA and MPO and significant increase in SOD concentrations compared with the I/R + V group, indicating a protective effect against I/R oxidative damage (P = 0.009, P = 0.006, P = 0.002, P = 0.003 and P = 0.009, respectively). Histopathological evaluation revealed MMF treatment resulted in significantly less tissue and cellular damage and apoptosis compared with the I/R + V group. These results indicate MMF is effective in attenuating uterine tissue damage and preventing apoptosis following uterine I/R injury, probably via anti-inflammatory and anti-oxidative action.

Major determinants of survival and length of stay in the neonatal intensive care unit of newborns from women with premature preterm rupture of membranes.

OBJECTIVE: To assess the predictors of outcome in terms of length of stay in the neonatal intensive care unit (NICU) and survival of neonates from women with preterm premature rupture of membranes (PPROM). METHODS: A population-based retrospective study including 331 singleton pregnant women with PPROM at 24-34 gestational weeks between January 2013 and December 2015 was conducted. Gestational age at delivery, birth weight, route of delivery, newborn gender, maternal age, oligohydramnios, premature retinopathy (ROP), necrotising enterocolitis (NEC), sepsis, fetal growth retardation (FGR), intracranial hemorrhagia (ICH), bronchopulmonary dysplasia (BPD), respiratory distress syndrome (RDS), primary pulmonary hypertension (PPH), congenital cardiac disease (CCD), patent ductus arteriosus (PDA), use of cortisol (betamethasone) and maternal complications including gestational diabetes, preeclampsia and chorioamnionitis were used to predict neonatal outcomes in terms of length of stay in the NICU and survival. RESULTS: In linear regression analyses, birth weight, ROP, CCD, BPD, PDA, NEC and preeclampsia were significant confounders for length of stay in the NICU. Among them, birth weight was the most powerful confounder for prolongation of the NICU stay (t: -6.43; p < 0.001). In multivariate logistic regression analyses, birth weight, PDA, ROP and PPH were significantly correlated with neonatal survival. PPH was the most powerful confounder in neonatal survival (ß: 7.22; p = 0.005). CONCLUSION: Prematurity-related complications are the most important problems for which precautions should be taken. Therefore, premature deliveries should be avoided to prevent infection and to prolong the latent period in cases of PPROM in order to decrease prematurity-related outcomes.

Effects of closure versus non-closure of the visceral and parietal peritoneum at cesarean section: does it have any effect on postoperative vital signs? A prospective randomized study.

OBJECTIVE: To investigate the effect of peritonization at cesarean section on postoperative vital signs which was thought to be an indirect finding secondary to increased sympathetic activity originated from pain caused by stretched peritoneum. METHODS: One hundred and thirty-three pregnant women were randomized to four groups; Closure of parietal peritoneum only (group 1; n = 32), closure of visceral and parietal peritoneums (group 2; n = 32), no closure of peritoneums (group 3; n = 32) and closure of the visceral peritoneum only (group 4; n = 32). All participants were monitored for blood pressure, pulse activity and hourly urinary output during the first postoperative 24 h. Postoperative pain was measured using a Visual Analogue Scale 6th and 24th hours after surgery. Return of bowel function was measured from the end of the operation to the first passage of flatus. Operating time, pre- and postoperative hemoglobin, postoperative complications, length of hospital stay and postoperative urine osmolarity were noted. RESULTS: The mean surgery duration was significantly longer in group 2. Diuresis was found significantly decreased in group 2. Pulse rate and systolic and diastolic blood pressure were significantly higher in group 2. Closure of both peritoneums was associated with higher post-operative pain as assessed using Visual analogue scale score analyses in group 2. CONCLUSION: Both visceral and parietal membrane closure in cesarean section should be avoided in women with hypertensive disorders, renal function abnormalities and autonomic dysfunction because of increased postoperative pain and associated sympathetic overactivity.

Evaluation of the maternal and fetal risk factors associated with neonatal care unit hospitalization time.

OBJECTIVE: To evaluate maternal and neonatal risk factors associated with the length of hospital stay in the neonatal intensive care unit (NICU). MATERIAL AND METHOD: This retrospective observational study was based on 3607 newborns who were admitted to the NICU of a tertiary teaching hospital from January 2012 through December 2014. Known obstetric risk factors associated with duration of hospitalization in NICUs were assessed including intrauterine growth restriction, maternal diabetes, oligohydramnios, chorioamnionitis, premeture rupture of membranes, preeclampsia, congenital malformations, neonatal sepsis, premature retinopathy, intracranial bleeding, necrotizing enterocolitis, meconium aspiration, maternal hypertension, fetal congenital cardiac malformations, congenital metabolic diseases, congenital hypothyroidism, pneumonia, pulmonary hypertension, bronchopulmonary dysplasia, pneumothorax and respiratory distress syndrome. RESULTS: Gestational age (beta coefficient: -0.244, p<0.001) and birth weight (beta coefficient: -0.237, p<0.001) were significant confounders for duration of hospitalization in newborns. CONCLUSION: Gestational age and the birth weight were the most important confounders for duration of hospitalization. Neonate care in developing countries would further benefit from additional large population-based long-term studies with broad parameters.

Sirenomelia: a review of embryogenic theories and discussion of the differences from caudal regression syndrome.

OBJECTIVE: To discuss the pathological features of sirenomelia in the light of our 10 cases and review the current theories. METHODS: We identified 10 patients with sirenomelia from our hospital database. All clinical details and the autopsy features of 10 cases were noted. RESULTS: Of the 10 children with sirenomelia seven had bilateral renal agenesis, three had bladder agenesis and one had a renal hypoplasia. Single umbilical artery was found in 60% of children with sirenomelia. External genitalia was ambiguous in seven of 10 patients. CONCLUSIONS: Even though the etiology of caudal regression syndrome (CRS) and sirenomelia remains unknown we tend to believe that sirenomelia and CRS might be different entities.

Evaluation of Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio and Red Blood Cell Distribution Width-Platelet Ratio for Diagnosis of Premature Ovarian Insufficiency.

Objective: To evaluate whether systemic inflammatory markers (neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and red blood cell distribution width (RDW) to platelet ratio (RPR)) can be used as reliable markers for the diagnosis of premature ovarian insufficiency (POI) and to determine if there is a relationship between these markers and follicle stimulating hormone (FSH), Anti-Müllerian Hormone (AMH) levels. Materials and methods: Written and electronic medical records were reviewed using searches for diagnoses with the terms of 'premature ovarian failure', 'premature ovarian insufficiency'. Patients younger than the age of 40 were diagnosed to have premature ovarian insufficiency based on their menstrual history and sonographic examination and they were compared with healthy females. Complete blood counts, day-3 hormone profiles, AMH levels of all subjects were analyzed. Results: NLR was statistically higher in POI group compared with controls (p < 0.05). NLR had a positive correlation between FSH (r = 0.23, p = 0.045) and a negative association with AMH (r = - 0.27, p = 0.018). The area under ROC curve for NLR in POI was 0.66, with a threshold value 1.5 and sensitivity = 75.7 % and specificity = 46.0 %. Conclusion: NLR can be a marker for the diagnosis of POI. There is a close relationship between NLR and ovarian reserve markers such as FSH and AMH.
