Human epididymis protein 4 and fetal lung maturity.

OBJECTIVES: To document the maternal and fetal cord blood levels of human epididymis protein 4 (HE-4) in term and preterm newborns in order to investigate the possible physiological role of HE-4 in fetal lung development. METHODS: This cross-sectional study was conducted in a university-affiliated hospital between April 2018 and September 2018. The study population consisted of cesarean section (C-section) deliveries after 24 weeks of pregnancy. Both maternal and umbilical cord HE-4 levels (mHE-4 and uHE-4, respectively) were measured using chemiluminescent microparticle immunoassay. Amniotic fluid was sampled from each case to determine the lamellar body count (LBC) as the gold standard test for lung maturation. All the parameters, including the uHE-4 levels, were compared between the term delivery (≥37 weeks) (n=52) and preterm delivery (24-37th weeks) (n=30) groups. The best cut-off value of uHE-4 was calculated for fetal lung maturity. RESULTS: There were no statistically significant differences between the groups regarding the demographic data. The mHE-4 levels did not statistically significantly differ between the groups (p>0.05) whereas the uHE-4 level of the preterm newborns was significantly higher than that of the term newborns (p<0.05). There was a significant negative association between the uHE-4 level and LBC (r=-0.389; p<0.001). The uHE-4 level was the only statistically significant fetal parameter indicating fetal lung maturity confirmed by LBC. At a cut-off value of 281 pmol/L, uHE-4 had 96.8% sensitivity, 45% specificity, 84.5% positive predictive value, and 81.8% negative predictive value for fetal lung maturity. CONCLUSIONS: Although the exact physiological role of HE-4 has not yet been elucidated, this preliminary study supports the idea that HE-4 plays a role in fetal lung maturation to some extent.

Evaluation of plasma cholecystokinin levels and gallbladder functions in hyperemesis gravidarum: a prospective cohort study.

This is a prospective cohort study aimed to compare women treated due to hyperemesis gravidarum (HG) (n = 24) to women with normal pregnancy attending regular antenatal outpatient care (n = 22) in terms of fasting and post-prandial cholecystokinin (CCK) levels, and gallbladder (GB) functions. The Pregnancy-Unique Quantification of Emesis (PUQE) scores, fasting and postprandial CCK levels, and ultrasonographic GB parameters were recorded at admission before any treatment. The median PUQE score in the study group was 8. There were no statistically significant differences in GB parameters (p>.05), and fasting and postprandial CCK levels between the groups (p=.851, p=.395, respectively). Fasting CCK levels were positively correlated with postprandial GB volume (PGv) (p=.022, r = 0.464). Although GB contractility is compromised during pregnancy, HG does not cause further GB impairment. The positive correlation between fasting CCK levels and PGv requires further evaluation. Impact StatementWhat is already known on this subject? The pathophysiology of hyperemesis gravidarum (HG) remains poorly understood. Altered cholecystokinin (CCK) levels may have potential consequences on gastric emptying, which may be related to nausea and vomiting. In this context, alterations in CCK secretion in women diagnosed with HG have been previously reported, and alterations in CCK levels lead to impaired gallbladder (GB) functions.What do the results of this study add? CCK levels and GB functions in pregnant women with HG are not statistically significantly different from those in healthy pregnant women.What are the implications of these findings for clinical practice and/or further research? Further studies designed in patients with different severities of HG and larger sample sizes are required for a better understanding of HG pathophysiology.

The assessment of the relationship between the vascularity of FIGO Type 4-7 leiomyomas and abnormal uterine bleeding.

The current study aimed to analyse and compare the vascularity of FIGO Type 4-7 leiomyoma specimens obtained from women with or without abnormal uterine bleeding (AUB). The records of 31 women who underwent myomectomy for FIGO Type 4-7 leiomyomas in a university hospital setting were analysed. Group I (n = 16) was composed of women that were symptomatic for AUB and group II (n = 15) consisted of asymptomatic cases. The myomectomy material(s) of each case were processed with CD34 staining and evaluated by Image J® software (Image J 1.52a, Wayne Rasband National Institutes of Health, Bethesda, MD). There was no statistically significant difference between the rates of vascular areas in the specimens of the two groups (p>.05). Although areas with large vessels were higher in group I compared to group II, the difference did not reach statistical significance (p>.05). AUB caused by FIGO Type 4-7 leiomyomas seems to be related to factors other than vascular density.Impact StatementWhat is already known on this subject? Uterine leiomyomas are the most common benign gynaecologic neoplasms with a prevalence of approximately 40% in women of reproductive age. They are most often asymptomatic but when symptomatic, abnormal uterine bleeding (AUB) is one of the most commonly observed symptoms. Although there are some hypothetical explanations, the exact pathogenesis underlying leiomyoma-associated AUB has not yet been elucidated. Almost a century ago, the vascular abnormalities of fibroids were hypothesised as one of the etiopathological factors correlated with clinical symptoms, such as AUB, and current data suggest that the vascular map of leiomyomas consists of an avascular core surrounded by a vascularised capsule. To our knowledge, there are no studies in the literature comparing the histopathological evaluation of the vascularity scores of FIGO Type 4-7 leiomyomas in symptomatic (with AUB) and asymptomatic (without AUB) women.What the results of this study add? The study revealed that there was no statistically significant difference between the vascularity scores of FIGO Type 4-7 leiomyomas excised from the symptomatic and asymptomatic women. Large vessel densities also did not statistically significantly differ between the two groups.What the implications are of these findings for clinical practice and/or further research? This study revealed that AUB caused by FIGO Type 4-7 leiomyomas was related to factors other than vascular density.

Pro-Gastrin Releasing Peptide: A New Serum Marker for Endometrioid Adenocarcinoma.

BACKGROUND: Gastrin-releasing peptide (GRP) is thought to play a role in the metastatic process of various malignancies. The more stable precursor of GRP, pro-GRP (ProGRP), has been shown to be secreted by neuroendocrine tumors. This study was designed to assess the validity of ProGRP as a diagnostic marker in endometrioid adenocarcinomas (EAs) of the endometrium. METHODS: Thirty-seven patients with a diagnosis of EA, 23 patients with endometrial hyperplasia, and 32 age-matched controls with normal endometrial histology were recruited for this study. Serum ProGRP and cancer antigen 125 (CA125) values were compared between groups. RESULTS: Median serum ProGRP levels were significantly higher in the cancer group compared to corresponding levels in both the hyperplasia and control groups (p = 0.008 and p < 0.001 respectively; endometrial cancer: 27.5 pg/mL; hyperplasia: 16.1 pg/mL; controls: 12.9 pg/mL). Age and endometrial thickness were positively correlated with ProGRP levels (r = 0.322, p = 0.006 and r = 0.269, p = 0.023, respectively). Receiver Operating Characteristic curve analyses for EA revealed a threshold of 20.81 pg/mL, with a sensitivity of 60.7% and specificity of 81.4%, positive predictive value of 68% and negative predictive value of 76.1%. CONCLUSION: Significantly higher ProGRP levels were observed in patients with EA than in controls. Serum ProGRP has good diagnostic sensitivity and specificity for EA.

The impact of nuchal cord on umbilical cord blood gas analysis and ischaemia-modified albumin levels in elective C-section.

This study was designed to evaluate umbilical cord ischaemia-modified albumin (IMA) levels and the cord blood gas parameters of foetuses with or without nuchal cords, at the time of elective C-section. The cross-sectional study population consisted of the patients who were admitted to the Tertiary Care Center between February and June 2015. Women with uncomplicated single term gestations between 37 and 40 completed weeks and scheduled for elective C-sections were included in the study. Fifty cases with a nuchal cord and 50 cases without a nuchal cord were recruited. Nuchal cord blood gas analysis and the IMA levels were evaluated. The IMA levels in umbilical artery of foetuses both in the study and control groups were similar (0.714 ± 0.150 vs. 0.689 ± 0.107 ABSU, p = .340, respectively). The umbilical artery pH values of the study group were significantly lower than that in the control group (7.31 ± 0.04 vs. 7.32 ± 0.03, p = .042; respectively). The results of the current study indicate that the nuchal cord has an impact on the foetal cord blood gas parameters to some extent before the initiation of labour. Fortunately, this impact does not end up with foetal tissue ischaemia, as confirmed by the IMA levels. Impact statement What is already known on this subject? The impact of nuchal cord on perinatal outcomes has been the subject of research for many years. Although the accumulated data has pointed out some unfavourable perinatal effects, the heterogeneity of the study groups both including a vaginal delivery and C-section and the inability to adjust the interfering factors ended up with some controversies. This is why there is not much known about the effects of the nuchal cord in women who are not in the labour process. What do the results of this study add? The current study aimed to exclude the interfering effects such as the active stage of labour. In this study, elective caesarean sections were selected as the study population to evaluate the effects of the nuchal cord on cord blood gas parameters and the IMA values. pH analysis in cord blood is used to detect hypoxia and the IMA is a new ischaemia marker. The results revealed that the in utero nuchal cord is associated with a significantly higher pCO2 and lower pH values and similar IMA values. What are the implications of these findings for clinical practice and/or further research? The final outcome supports that the nuchal cord causes alterations in cord blood gas analysis but this does not reach critical levels. Therefore, the results show that there is no need to change clinical practice when the nuchal cord is detected by ultrasound in a term gestation.

The Impact of Gradually Increasing Energy Dose on AMH Levels in Ovarian Drilling.

BACKGROUND: To document alterations in Anti-Müllerian hormone (AMH) levels with different energy doses by monopolar cautery in ovarian drilling (OD) in rats. METHODS: Forty Wistar rats were randomly divided into 4 groups that each contained 10 animals. Group A was the Sham group. Groups B, C and D were intervention groups to which OD was applied by monopolar cautery, with 20, 60 and 120 J/ovary, respectively. The total amount of energy was calculated using the following formula: energy (J) = power (W) × duration (s) × number of punctures. RESULTS: The pre- and postoperative AMH levels for Groups A, B and C were not statistically and significantly different according to the Bonferroni correction (p > 0.0125). However, the postoperative AMH levels were significantly lower than the preoperative AMH levels in Group D (1.25 ng/ml (1.07-2.05) vs. 0.40 ng/ml (0.30-0.72); p = 0.012). CONCLUSIONS: AMH is a promising marker that can be used for the individualization of the energy dose to increase OD success, but the relationship between the energy and AMH has not been documented yet. This study demonstrates that postoperative changes in AMH levels could be observed only after a certain amount of energy was applied. Further experimental animal models are needed to conclusively address this issue.

Ischaemia-modified albumin in preeclampsia: A critical view.

The aim of the study was to compare ischaemia-modified albumin (IMA) levels, both original and corrected, in healthy pregnancies and pregnancies complicated with preeclampsia. Maternal and cord blood samples from study (n = 16) and control (n = 17) groups were collected at the time of delivery. IMA levels were given in absorbance units (ABSU). IMA levels, both original and corrected, were compared between study and control groups. No significant difference was found between maternal and cord blood IMA levels between the study and control groups [1.0 (0.3-3.5) vs 1.2 (0.2-1.4) ABSU, p = .053 and 1.0 (0.1-2.2) vs 0.9 (0.4-3.6) ABSU, p = .382, respectively]. The results were similar for maternal IMA levels, after correction of IMA levels [1.1 (0.3-5.1) vs 1.2 (0.2-1.6) ABSU, p = .292]. IMA is a novel marker for ischaemia, without precise conclusions about its value in preeclampsia. An absolute correction formula, considering all possible intervening factors, is required for more accurate results.

Controlled ovarian hyperstimulation with sequential letrozole co-treatment in normo/high responders.

OBJECTIVE: To investigate the effect of co-administration of letrozole in an ovarian stimulation protocol using recombinant FSH and GnRH antagonists for ICSI in normo/high responders. METHODS: Computerized data of 320 antagonist ICSI/ET cycles with or without letrozole were retrospectively analyzed. In 105 cases, letrozole (5 mg/day) was started at the second day of the cycle continued for 5 days. At the second day of letrozole, gonadotropins were added. The remaining 215 cases were stimulated with recombinant FSH only. In all cases on day 6, GnRH antagonist was started. Ovarian stimulation protocols with or without letrozole were compared for cycle outcome parameters. RESULTS: In cycles with letrozole, significantly lower gonadotropin consumption and lower peak estradiol levels were found. In cycles with letrozole, mean number of metaphase II and fertilized oocytes retrieved were significantly higher compared to cycles without letrozole. The pregnancy and clinical pregnancy rates were similar. CONCLUSION: Should the number of oocytes retrieved being higher in letrozole group might indicate that letrozole might contribute to successful ovarian stimulation with a lower dosage of gonadotropins. Despite the lower peak estradiol levels, pregnancy rates being similar to other group also support the idea that letrozole can contribute to normal potential of implantation.

Estrogen or anti-estrogen for Bologna poor responders?

The current study aims to compare cycle outcomes of two ovarian stimulation protocols in poor responders according to the Bologna criteria; luteal estrogen priming (LE) or letrozole (LZ) co-treatment in antagonist protocol. Following retrospective chart review of a single center, 162 cycles were found eligible for the comparison of two ovarian stimulation protocols. After interpreting data, significantly higher serum estradiol levels, longer duration of cycle, higher number of fertilized oocytes and good quality embryos were detected in patients who received LE. Despite any statistical significance, higher clinical pregnancy rate (CPR) and ongoing pregnancy rate (OPR) per embryo transfer (ET) were detected with LE protocol compared with LZ (12.3% versus 18.2% and 9.6% versus 12.7%, respectively). Younger patients (<40 years) revealed higher CPR and OPR per started cycle compared with older patients (≥40 years) where only OPR was statistically significant. Multivariable analysis demonstrated that basal antral follicle count, peak serum estradiol levels and number of fertilized oocytes were independent variables significantly associated with clinical pregnancies (p < 0.05). In the current analysis, LE or LZ protocols revealed comparable but quite low pregnancy rates in poor responders according to the Bologna criteria. Younger patients were more likely to achieve pregnancy compared to older patients with both protocols.

Early second trimester retinol-binding protein-4 values in cases with or without gestational diabetes mellitus risk factors: a cross-sectional study.

AIM: Retinol-binding protein-4 (RBP-4) has been correlated with different degrees of insulin resistance including gestational diabetes mellitus (GDM). Presence of risk factors for GDM is an indication for early screening. We studied RBP-4 values in the early second trimester of pregnancy in pregnant subjects with or without GDM risk factors and compared the results by routine GDM screening methodology. METHODS: Seventy-nine patients with at least one GDM risk factor and 46 patients without any GDM risk factors were enrolled in the cross-sectional study as risk and control groups, respectively. In the early second trimester, RBP-4 values were measured, in addition to fasting plasma glucose and 50-g glucose challenge test in all subjects. RESULTS: The RBP-4 values in 16-18th weeks of pregnancy were not significantly different between risk and control groups (95.3 ± 20.1 vs 103.1 ± 24.4 µg/mL, respectively; P = 0.055) although fasting plasma glucose levels and 50-g glucose challenge test results were higher in the risk group than the control group (75.3 vs 69.3 mg/dL and 112.4 vs 97.5 mg/dL, respectively; P < 0.05). CONCLUSION: Presence of GDM risk factors does not have an impact on early second trimester RBP-4 values in pregnant subjects.

Improved cycle outcomes after laparoscopic ovarian diathermy in hyper-responder patients with previous ART failure.

Excessive response to ovarian stimulation is common among hyper-responder patients undergoing assisted reproductive technology (ART). Cycle cancellations and severe ovarian hyperstimulation syndrome (OHSS) are all detrimental consequences observed within this cohort and several approaches have been proposed to enhance outcomes. The current study is designed to evaluate whether laparoscopic ovarian diathermy (LOD) improves ART outcomes and pregnancy rates by reducing Anti-mullerian hormone (AMH) levels in a group of patients who had a history of recurrent ART failure and high response. A total of 40 hyper-responder patients with history of previous ART failure were included. Group I consisted of 22 patients that underwent LOD prior to ART. Group II consisted of 18 patients that underwent only ART. Cycle outcomes of groups were compared. Following LOD, significant reduction in AMH levels were detected in group I (4.75 ng/mL to 2.25 ng/mL). Clinical pregnancies were similar among groups (40% versus 27.8% p = 0.65). There was no cycle cancellation in Group I, whereas there were three cycle cancellations observed due to OHSS in Group II. Our results indicate that LOD might offer enhanced fertility outcomes and may reduce the likelihood of cycle cancellations in hyper-responders with previous ART failures.

The association between prolactin, high-sensitivity C-reactive protein and Framingham risk score in menopause.

AIMS: To evaluate the association between serum prolactin, high-sensitivity C-reactive protein (hs-CRP) levels and cardiovascular disease risk in postmenopausal women regarding the Framingham Risk Score (FRS). METHODS: Fifty-eight menopausal women were enrolled into the cross-sectional study. All participants had 24-hour ambulatory blood pressure monitoring, echocardiography, electrocardiography, and carotid intima-media thickness measurement. Blood samples were obtained for prolactin, hs-CRP, lipid profile, fasting glucose, and insulin. RESULTS: Among the participants, 67.24% had a FRS <10%, and 32.75% had a FRS ≥10%. Levels of prolactin and hs-CRP did not differ between the FRS groups. In the FRS <10% group, significantly higher levels of prolactin were found. Cases with hypertension have significantly higher levels of hs-CRP. Prolactin and hs-CRP were found to be associated with hypertension in the FRS <10% and ≥10% groups, respectively. CONCLUSIONS: Hypertensive postmenopausal women with low risk for cardiovascular diseases have increased levels of prolactin, suggesting a possible role in the pathogenesis of hypertension. The correlation of hs-CRP with systolic blood pressure can be interpreted as a potential effect of hypertensive heart disease reflecting a state of high-risk milieu with elevated inflammatory markers.

The impact of route of anesthesia on maternal and fetal ischemia modified albumin levels at cesarean section: a prospective randomized study.

OBJECTIVE: Ischemia modified albumin has been shown to increase in ischemic situations, and has also been shown to increase in fetal cord blood in deliveries by cesarean section. The aim of this study is to reveal whether anesthesia has an impact on maternal and fetal cord ischemia modified albumin levels. METHODS: Seventy two women with uncomplicated term pregnancies were randomized to spinal (n=37) or general anesthesia (n=35) groups. The blood pressure, oxygen saturation, and pulse rate of the patients were recorded during the procedure. Maternal blood samples of ischemia modified albumin (IMA) were taken 10 min from the start of the procedure. The fetal cord blood samples of IMA were taken immediately after birth. RESULTS: Maternal (0.99 ± 0.19 vs. 0.80 ± 0.27) and fetal (1.00 ± 0.21 vs. 0.70 ± 0.26) IMA levels were significantly higher in the general anesthesia group. Fetal IMA levels were positively correlated with maternal gravidity (r=0.31; P=0.008), parity (r=0.25; P=0.028), and fetal birth weight (r=0.23, P=0.045). Also, as time from incision to delivery lengthens, fetal IMA levels increase (r=0.29, P=0.012). CONCLUSION: Fetal cord ischemia modified albumin levels were higher in the general anesthesia group, therefore, it is proposed that regional anesthesia should be the preferred route of anesthesia for an elective cesarean section, at least until the impact of high fetal cord IMA levels are manifested.

Anti-Mullerian hormone and insulin resistance in classic phenotype lean PCOS.

PURPOSE: This study is designed to explore the correlation between AMH levels and IR in normal weight PCOS women. MATERIALS AND METHODS: This prospective study was conducted on 55 patients, who were admitted to obstetrics and gynecology department of a university clinic. Study group was consisted of 34 patients diagnosed as polycystic ovary syndrome (PCOS) according to the Rotterdam Criteria, whereas control group was consisted of 21 healthy volunteers without any features of clinical or biochemical hyperandrogenism, who had regular menstrual cycles. BMI ≥ 25 kg/m(2) were considered overweight and obese and excluded. Blood samples were obtained during days 2-3 after spontaneous menses or progesterone-induced withdrawal bleeding after overnight fasting for at least 12 h. The weight, height, hip and waist circumferences of the patients were measured. Fasting insulin and glucose (FPG) levels were used for calculating different insulin resistance indexes (Homeostatic Model Assessment (HOMA-IR), Quantitative Insulin Sensitivity Check Index (QUICKI)). RESULTS: No significant difference was found between PCOS and control groups regarding the mean age, BMI, waist to hip ratio (WHR), mean values of FPG, FPG/insulin ratio and HOMA B (p > 0.05). AMH values were significantly higher in PCOS cases when compared with controls (4.7 vs. 3.4 ng/mL) (p < 0.05).The mean values of HOMA-IR and QUICKI indexes were significantly higher among PCOS cases when compared with controls. E2 levels were significantly lower and Total-T were significantly higher in PCOS patients. When PCOS cases are categorized according to the existence of IR, no difference in Total-T and AMH levels between both groups. Although not statistically significant, a negative correlation of AMH with HOMA-IR and a positive correlation with QUICKI index were found. Among the hormone parameters, AMH was found to be positively correlated with Total-T (r = 0.332, p = 0.013). CONCLUSION: Although the relation between AMH and androgen production is supported by current evidence, the mechanism underlying the relation between AMH and insulin resistance is not clear yet.

Evaluation of visceral adiposity index with cardiovascular risk factors, biomarkers in postmenopausal women to predict cardiovascular disease: A 10 year study.

BACKGROUND AND AIM: Visceral adiposity index (VAI) is reportedly beneficial in predicting cardiovascular disease (CVD) and metabolic syndrome (MetS). However, long-term studies analyzing the efficacy of VAI in the prediction of CVD risk are limited. The relationship between VAI and electrolytes is unclear. This study aimed to determine if VAI can be used as a predictor of CVD and provide early diagnosis possibility for future CVD patients. Moreover, the impact of biomarkers and electrolytes on VAI therefore indirect relation to CVD was analyzed. METHODS: Postmenopausal women (aged >40 years) admitted to our hospital in 2011 were included and categorized into two groups according to their VAI scores: mild/moderate and severe. Groups were compared with insulin resistance, biochemical parameters, and anthropometric measurements. Patients have been reached out after 10 years and questioned for additional disease and cardiovascular risk. Statistical Package for Social Sciences (SPSSv22.0) was used for data analysis. The p < 0.05 value was considered significant. RESULTS: Mean VAI score of patients with MetS (7.30 ± 4.75) was significantly higher than without MetS (2.95 ± 1.05) (p < 0.01). Serum magnesium level was found significantly lower in the severe group. Serum zinc (Zn) and hsCRP levels were higher in the severe group. Correlation analysis showed significant positive correlations between VAI scores and total cholesterol (r = 0.289, p < 0.05), Zn (r = 0.397, p < 0.01), fasting insulin (r = 0.455, p < 0.01) and no significant association with the 10-year CVD incidence (OR: 1.034 (0.888-1.203); p = 0.668). CONCLUSION: Previous VAI results cannot assist in predicting the 10-year CVD risk. Additionally, including measurements of serum Zn, total cholesterol, fasting insulin, and FBG levels are reasonable approach for managing postmenopausal women with unfavorable CVD risk profiles.

Pre-test anxiety levels and postoperative pain in non-obstructive azoospermic patients: Is klinefelter syndrome a predisposing factor?

INTRODUCTION: Increased depression and anxiety incidence in infertile individuals treated with assisted reproductive techniques have been shown in studies. Postoperative pain perception after testicular sperm extraction (TESE) is thought to be related to preoperative anxiety in non-obstructive azoospermia (NOA). MATERIALS AND METHODS: Twenty patients with Klinefelter syndrome (KS) and twenty male patients with normal karyotype NOA planned for TESE under local anaesthesia due to azoospermia were included in the study. Spielberger State-Trait Anxiety Inventory (STAI-T and STAI-S) inventory was given to all patients 1 h before surgery. Postoperative pain evaluation was performed at 0, 30, 60 and 120 min with visual analogue scale (VAS). STAI-T inventory was given to the patients again 2 h after the procedure. RESULTS: Preoperative STAI-S and STAI-T scores and postoperative STAI-T scores of patients in the KS group were higher than those in the NOA group, and there was a significant difference in the statistical analysis between the two groups (p < 0.001). In the postoperative VAS scores, there was no statistical difference at the 0 and 120th min (p = 0.56 and p = 0.87, respectively); at the 30, 60 and 90th min there was a statistically significant difference between the two groups, especially in patients in the KS group (p < 0.05, p < 0.05, p < 0.01, respectively). CONCLUSION: The contribution of anxiety to pain perception should be kept in mind in azoospermic male patients before TESE, and additional measures should be taken considering that this may be experienced at a higher level in KS patients.

Myo-inositol oxygenese activity in second trimester of pregnancy: altered myoinositol catabolism in gestational diabetes mellitus.

OBJECTIVE: We aimed to determine myo-inositol oxygenase (MIOX) activity in gestational diabetes mellitus (GDM). MATERIAL AND METHODS: The insulin, HbA1c, and MIOX levels of 80 pregnant women were analysed after 75 g OGTT. Group I included patients with no risk factor for GDM, Group II: patients with high risk for GDM, and Group III: GDM patients. RESULTS: Fasting plasma glucose and Homeostatic Model Assessment for Insulin Resistance index were significantly higher in GDM cases (Group 3). Regarding the MIOX levels, significantly higher levels were recorded at 0-h in Group 3 compared to Groups 1 and 2. Significant alteration in MIOX activity was found between 0- and 2-h in Group 3 compared to Groups 1 and 2 (p < .029). CONCLUSIONS: MIOX levels were higher in GDM cases so, it may be have a role in myo-inositol catabolism.

Hemodynamic outcome of different ventilation modes in laparoscopic surgery with exaggerated trendelenburg: a randomised controlled trial.

PURPOSE: To compare hemodynamic effects of two different modes of ventilation (volume-controlled and pressure-controlled volume guaranteed) in patients undergoing laparoscopic gynecology surgeries with exaggerated Trendelenburg position. METHODS: Thirty patients undergoing laparoscopic gynecology operations were ventilated using either volume-controlled (Group VC) or pressure-controlled volume guaranteed mode (Group PCVG) (n = 15 for both groups). Hemodynamic variables were measured using Pressure Recording Analytical Method by radial artery cannulation in addition to peak and mean airway pressures and expired tidal volume. RESULTS: The only remarkable finding was a more stable cardiac index in Group PCVG, where other hemodynamic parameters were similar. Expired tidal volume increased in Group VC while peak airway pressure was lower in Group PCVG. CONCLUSION: PCV-VG causes less hemodynamic perturbations as measured by Pressure Recording Analytical Method (PRAM) and allows better intraoperative hemodynamic control in exaggerated Trendelenburg position in laparoscopic surgery.

Erectile function in SRY positive 46,XX males with normal phenotype.

INTRODUCTION: The 46,XX male syndrome is a rare disorder of sex development and has two different forms, depending on the sex-determining region's presence on the Y chromosome (SRY) gene. The SRY positive 46,XX males are usually diagnosed during infertility workup. We evaluated the erectile function of 46,XX SRY positive males and compared it with healthy males. MATERIAL AND METHODS: Ten patients with azoospermia and 46,XX SRY positive disorder who referred to a urology clinic with infertility were analyzed retrospectively. Controls were chosen from healthy males at similar ages. The physical examination was performed, and serum hormones were obtained at admission. The clinical assessment of erectile dysfunction was evaluated by the International Index of Erectile Function (IIEF) questionnaire. RESULTS: There was no statistically significant difference between the two groups in terms of age, serum prolactin, luteinizing hormone (LH) levels and IIEF scores (P >0.05). In 46,XX males, serum follicle-stimulating hormone (FSH) levels were significantly higher, and total testosterone levels and testicular volumes were found to be significantly lower when compared to controls (p <0.001, p <0.05, p <0.01, respectively). CONCLUSIONS: This study indicates that these males' erectile function is similar to those of 46,XY males.
