The effect of steroid administration on fetal diaphragm function.

BACKGROUND: Antenatal steroid administrations lead to not only accelerated lung maturation, improved blood gas measurements but also lung dynamics and lung compliance. This study aimed to investigate structural and functional changes in diaphragm after antenatal steroid administration. METHODS: The 79 volunteers were divided into 2 groups according to presence of preterm delivery. Betamethasone (CelestoneR) 12 mg intramuscularly was routinely administered to pregnancies complicated with preterm delivery between 28th -34th weeks of gestation. Same dose was repeated 24 h later. In all patients, diaphragm thickness, diaphragmatic excursion and costophrenic angle were measured in both the inspirium and expirium stage of respiration. This is an observational cross-sectional study. RESULTS: Diaphragm thickness, diaphragmatic excursion and diaphragm thickening fraction parameters were improved but costophrenic angle was not different 7 days after steroid administration. Diaphragm thickness, diaphragmatic excursion and costophrenic angle changes during inspiration and expiration stage after 7 days of betamethasone treatment reflects the effect of steroid administration on diaphragm muscle. Comparisons of the differences that occur after steroid rescue protocol were done by subtracting the diaphragm thickness, diaphragmatic excursion and costophrenic angle parameters before the treatment from the diaphragm thickness, diaphragmatic excursion and costophrenic angle parameters 7 days after steroid treatment respectively. CONCLUSION: Diaphragm became more mobile in patients with preterm labor, 7 days after steroid administration. This situation reflects positive effect of steroid administration on diaphragm function.

Evaluation of fetal diaphragm excursion and thickness in term pregnancies complicated with pre-gestational and gestational diabetes mellitus.

BACKGROUND: Both pre-gestational (PGDM) and gestational diabetes mellitus (GDM) make pregnancy complicated. Moreover in the literature GDM and PGDM have been held responsible for respiratory morbidity in newborns. Diaphragm ultrasound (DUS) is a valuable and noninvasive method that provides an opportunity to examine the diaphragmatic morphology and function. This study examined the quality of fetal diaphragmatic contractions in pregnant women complicated with GDM and PGDM. METHODS: A total of 105 volunteers who were separated into three groups; (1) A GDM group (n = 35), (2) a PGDM group (n = 35), and (3) a healthy non-diabetic control group (n = 35). All volunteers with the cephalic presentation and only male fetuses were examined in the 37th week of gestation. This cross sectional and case controlled study was performed at the perinatology clinic of the Erciyes University School of Medicine between 15.01.2020 and 01.08.2021. The thickness of fetal diaphragm (DT), diaphragmatic excursion (DE), diaphragm thickening fraction (DTF) and costodiaphragmatic angle (CDA) was measured and recorded by ultrasound and examined on the video frame during the inspiration and expiration phases of respiration. RESULTS: Especially the PGDM group represented adversely affected diaphragm function parameters. DT inspiration, DT expiration, DE, CDA inspiration and DTF values were significantly different between PGDM and the control group. Neonatal intensive care unit (NICU) admission was high among babies who were born to pregnancies complicated with PGDM or GDM. CONCLUSIONS: The quality of fetal diaphragm movements is affected in pregnancies complicated with GDM and PGDM. The prolonged duration of diabetes may have additional adverse effects on diaphragm morphology and its function.

The percentage of pre-gestational diabetes mellitus (PGDM) in pregnancy is 13­21% and the remaining part of diabetes is gestational diabetes mellitus (GDM). Both of the complications are related to respiratory problems at birth.Until now, it was known that this situation was due to the lack of surfactant, which has a facilitating effect on the participation of the lungs in respiration. However, in this study, the diaphragm of the babies of patients with PGDM and GDM was examined. The thickness of fetal diaphragm, movements and function were evaluated via using ultrasound. As a result, it was determined that the diaphragm movements were impaired and the babies born from these patients needed more pediatric care.This study will open horizon on new studies examining the functional capacity of the diaphragm in the future. In the future, it may be possible to decide which baby will need intensive care by examining the diaphragm.

Evaluation of midtrimester ductus venosus diameter and peak systolic velocity to predict late onset small for gestational age fetuses.

OBJECTIVE: The ductus venosus, a small blood vessel in the fetal venous system, has extraordinary physiologic significance because it connects the umbilical vein to the inferior vena cava in the fetus circulation system and transports highly oxygenated blood from the placenta to the fetus' heart. Hence, assessment of ductus venosus flows is helpful in evaluating fetal hemodynamics. Considering the critical function of the ductus venosus, we hypothesized that the diameter of the midtrimester ductus venosus and its peak velocity index can be related to adequate fetal growth; therefore, the aim of this study was to evaluate the role of the midtrimester umbilical venous blood flow, ductus venosus diameter, and ductus venosus peak systolic velocity to help predict uncomplicated deliveries of late onset small for gestational age (SGA) fetuses. METHODS: In this prospective study we analyzed the pregnancies and deliveries of 398 pregnant women who met the inclusion criteria and divided them into three groups according to fetal birth weight as follows: birth weight <3 percentile SGA group (n = 16), birth weight 3-10 percentile SGA group (n = 42), and appropriate for the gestational age (AGA) group (n = 340). The midtrimester ductus venosus diameter and peak sistolic velocity, umbilical venous blood flow, and umbilical artery pulsatility index (PI) were recorded. In the absence of congenital anomalies, the diagnosis of fetal growth restriction (FGR) is made according to Delphi consensus criteria. In the absence of abnormal Doppler findings, late FGR was defined as occurring ≥32 weeks. RESULTS: Maternal age, nulliparity, mean gestational age at ultrasound evaluation, ethnicity, body mass index, and previous cesarean delivery rates were similar among the groups. In addition, mid-trimester fetal biometric measurements and amniotic fluid volume were similar among the groups. The gestational age at delivery, prematurity, fetal birth weight, vaginal delivery rates, and rate of admission to the neonatal intensive care unit were significantly different among the groups. The mean mid-trimester umbilical vein blood flow to abdominal circumference ratio (UVBF/AC) was similar among the groups (p=.740). In the <3 group, the mean peak systolic velocity of the ductus venosus was significantly lower and the mean diameter of the ductus venosus significantly higher than those in the 3-10 and AGA groups (both p<.001). Although the values are below the 95th percentile mid-trimester umbilical artery PI was significantly higher in the <3 percentile SGA group than in the 3-10 percentile SGA and AGA groups. CONCLUSION: Our results suggest that the diameter and peak systolic velocity of the mid-trimester ductus venosus are useful noninvasive measurements that provide prediction of late onset SGA fetuses.

The role of the brain-sparing effect of growth-restricted fetuses in newborn germinal matrix/intraventricular hemorrhage.

OBJECTIVES: The aim of the study was to evaluate the effect of the brain-sparing effect (BSE) of fetal growth restriction (FGR) in newborn germinal matrix/intraventricular hemorrhage (GM/IVH). METHODS: A total of 320 patients who delivered prior to the 34th gestational week were analyzed from data records. 201 patients were divided into two groups according to cerebro-placental ratio (CPR): early fetal growth restriction (FGR) with abnormal CPR group (n=104) and appropriate for gestational age with normal Doppler group (control) (n=97). Using the normal middle cerebral artery (MCA) Doppler as a reference, multivariate logistic regression analysis was used to assess the association between the BSE and the primary outcome. RESULTS: The rate of Grade I-II germinal matrix/intraventricular hemorrhage (GM/IVH) was 31(29.8%) in the group possessing early FGR with abnormal CPR and 7(7.2%) in the control group, showing a statistically significant difference. The rate of grade III-IV GM/IVH was 7(6.7%) in the group possessing early FGR with abnormal CPR and 2 (2.1%) in the control group, showing no statistically significant difference. We found that gestational age at delivery <32 weeks was an independent risk factor for GM/IVH. In addition, we found that other variables such as the presence of preeclampsia, fetal weight percentile <10, emergency CS delivery, 48-h completion after the first steroid administration and 24-h completion rate after MgSO4 administration were not independently associated with the primary outcome. CONCLUSIONS: Our results indicate that the rate of GM-IVH was increased in the group possessing early FGR with abnormal CPR; however, multivariate logistic regression analysis showed that BSE was not an independent risk factor for GM/IVH.

Effect of preeclampsia and its severity on maternal serum NGAL and KIM-1 levels during pregnancy and the post-pregnancy period.

OBJECTIVE: The purpose of this trial was to appraise the effects of preeclampsia and its intensity on maternal serum neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) levels during pregnancy and the post-pregnancy period. STUDY DESIGN: Firstly pregnant participants (n = 156) were separated into three groups, as control, mild, and severe preeclampsia. Secondly women in post-pregnancy period (n = 368) were separated into three groups according to history of pregnancy, as healthy control, mild, and severe preeclampsia. These women were identified through the hospital data system and contacted by telephone to participate in the study. RESULTS: Our study comprised 147 patients, 77 of whom were pregnant and 70 of whom were in their post-pregnancy period after the exclusion criteria had been applied. In terms of maternal serum NGAL levels, there is a significant increase in the severe preeclampsia group compared with that in the mild preeclampsia and normal pregnancy groups (p < 0.001). During the post-pregnancy period, the maternal serum NGAL levels were found significantly higher in the severe preeclampsia group than in the mild preeclampsia group and non-hypertension control group (p < 0.001). Maternal serum KIM-1 levels were found as significantly higher in the severe and mild preeclampsia groups than in the non-hypertension pregnancy group (p = 0.004). During the post-pregnancy period, maternal serum KIM-1 levels were found as similar among all post pregnant groups (p = 0.792). CONCLUSIONS: Our results indicated that as the severity of preeclampsia increases, kidney damage as assessed using NGAL levels continues for a long period of time, even during the post-pregnancy period.

Umbilical cord N-terminal procollagen of type l collagen (P1NP) and beta C-terminal telopeptide (ßCTX) levels in term pregnancies with vitamin D deficiency.

AIMS: The aim of the present study was to evaluate umbilical cord N-terminal procollagen of type l collagen (P1NP) and beta C-terminal telopeptide (ßCTX) levels in term pregnancies with vitamin D deficiency. MATERIALS AND METHODS: Ninety-two pregnant women between 19 and 35-years-old who delivered at term gestational age were included in the study and divided into deficient (n = 32), insufficient (n = 30), and normal (control) vitamin D levels (n = 30). RESULTS: Maternal demographic characteristics and biochemical parameters were similar among groups. The mean umbilical cord P1NP level was 221.4 (211.7-231.0, 95%CI) pg/mL in the vitamin D deficiency group, 282.5 (271.2-293.8, 95%CI) pg/mL in the vitamin D insufficiency group, and 280.9 (270.9-290.8, 95%CI) pg/mL in the control group and significantly lower in vitamin D deficiency group than others (p < .001). Umbilical cord P1NP level was similar in the vitamin D insufficiency group and control group (p = .971). The mean umbilical cord ßCTX level was 5530, 9 (5511.5-5550.3, 95%CI) pg/mL in the vitamin D deficiency group, 5516.3 (5498.4-5534.2, 95%CI) pg/mL in the vitamin D insufficiency group, and 5510 (5491.4-5528.5, 95%CI) pg/mL in the control group, which was statistically similar among the groups (p = .251). CONCLUSION: Our results indicated that vitamin D deficiency during pregnancy affects fetal bone osteoblast activity.

Adverse fetal outcomes in patients with IUGR are related with fetal diaphragm evaluation parameters.

INTRODUCTION: The aim of the present study was to evaluate the relationship between diaphragmatic thickness, during both inspiratory (DTI) and expiratory (DTE) stages; diaphragmatic excursion (DE); diaphragm thickening fraction (DTF); and adverse fetal outcomes in pregnant women with intrauterine growth restriction (IUGR). MATERIALS AND METHODS: A total of 77 participants were included in this case-control study. The case group was diagnosed as having both symmetric and asymmetric IUGR (n = 39). The control group included gestational age (GA)-matched healthy pregnant women (n = 38). DTI, DTE, DE (reflecting the capability of diaphragmatic movement during the respiratory cycle), and DTF were analyzed. RESULTS: Maternal demographic characteristics were similar between groups. DTI and DTE were significantly lower in the IUGR group compared to the control group (p < 0.001 and p < 0.001). DE was similar between the groups (p = 0.07). Additionally, in the IUGR group, DTI, DTE, and DE were significantly altered in newborns that required treatment in the neonatal intensive care unit (NICU). ROC curve analysis determined that the DTI cut-off was 1.36 for NICU admission with 78% sensitivity and 100% specificity. DTE cut-off was 1.195 for NICU admission with 78% sensitivity and 96% specificity. DE cut-off was 4.25 for NICU admission with 71% sensitivity and 80% specificity. CONCLUSION: Measurement of DTI, DTE and DE may help clinicians to predict whether newborns with IUGR would require NICU hospitalization.

Effect of preeclampsia and preeclampsia severity on insulin, HOMA-IR, and betatrophin levels in non-diabetic pregnant women.

BACKGROUND: The aim of the study was to evaluate the effect of preeclampsia and its severity on insulin, the homeostatic model assessment of insulin resistance (HOMA-IR), and betatrophin levels in non-diabetic pregnant women. METHODS: Our study comprised 102 pregnant women who were divided into the following three groups: (1) control, (2) severe preeclampsia, and (3) mild preeclampsia. The women were screened with the single-stage 75-g oral glucose tolerance test (OGTT), and the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria were used for diagnosis. Those women with type 2 diabetes (T2D) mellitus or gestational diabetes mellitus (GDM) were excluded from the study. RESULTS: Maternal demographic characteristics were similar among the groups. Fasting plasma glucose and postprandial 2-h plasma glucose levels were significantly increased in the severe-preeclampsia group compared to that in the other groups. Fasting insulin levels were 14.3 ± 8.7uU/mL in the severe-preeclampsia group, 19.1 ± 6.0uU/mL in the mild-preeclampsia group, and 20.5 ± 12.5uU/mL in the control group and significantly lower in the severe-preeclampsia group than in the mild-preeclampsia and control groups. The serum betatrophin level was 7.8 ± 2.6 ng/mL in the severe-preeclampsia group, 6.1 ± 1.8 ng/mL in the mild-preeclampsia group, and 5.8 ± 1.3 ng/mL in the control group and significantly increased in the severe-preeclampsia group compared to other groups. HOMA-IR was similar among the groups. Maternal serum insulin levels were negatively (r = -0,255; P = 0.010) and serum betatrophin levels were positively (r = 0.368; P ≤ 0.001) correlated with preeclampsia severity. CONCLUSION: Our results indicated that severe preeclampsia effect maternal serum glucose, insulin and betatrophin levels. Histhopatholical and immunohistochemical demostrations on pancreatic cells in new preeclampsia rat models will expand the information on the current situation.

Fetal Pulmonary Artery Acceleration/Ejection Ratio for Transient Tachypnea of the Newborn in Uncomplicated Term Small for Gestational Age Fetuses.

OBJECTIVE: Transient tachypnea of the newborn (TTN) is the leading cause of neonatal morbidity in preterm deliveries and has been reported in term small-for-gestational-age (SGA) fetuses; therefore, determination of fetal lung maturity before delivery is extremely important. Our present study aimed to evaluate the ratio of fetal pulmonary artery acceleration time to ejection time (At/Et) in uncomplicated term SGA fetuses and whether this ratio changes with TTN. STUDY DESIGN: One hundred seventy-five pregnant women with uncomplicated pregnancies who delivered after 37 gestational weeks were included in this cross-sectional study. Participants were divided by birth weight percentiles into SGA (n = 86) and healthy control groups (n = 89). All participants underwent ultrasound examination to determine fetal pulmonary artery At/Et. After delivery, the neonates were grouped according to diagnosis of TTN (i.e., TTN-positive SGA group [n = 14], TTN-negative SGA group [n = 72], and TTN-negative control group [n = 86]), and the fetal pulmonary artery At/Et was compared between the two. RESULTS: Maternal demographic characterizes were similar between groups. At/Et was 0.309 ± 0.181 in the SGA group and 0.348 ± 0.213 in the control group and was significantly lower in the SGA group. At/Et was 0.290 ± 0.007 in the TTN-positive SGA group, 0.313 ± 0.017 in the TTN-negative SGA group, and 0.351 ± 0.186 in the TTN-negative control group, a significant difference. Additionally fetal pulmonary artery At/Et was found to be inverse correlated with TTN. (-0,464 P = 0.000). The cut-off value of 0.298 provided optimal specificity of 93.0 % and sensitivity of 81.0 % for subsequent diagnosis of TTN in term SGA newborns in the neonatal period. CONCLUSION: The risk for TTN increases in uncomplicated term SGA fetuses. The fetal pulmonary artery At/Et appears to be a noninvasive useful method by which to predict TTN in these fetuses.

Effect of the anterior uterocervical angle in unexplained infertility: a prospective cohort study.

OBJECTIVE: The present study aimed to evaluate an anatomical region, the anterior uterocervical angle (UCA), to determine whether it plays a role in unexplained infertility. METHODS: In this prospective, cross-sectional study, unexplained infertile and healthy fertile (controls) women were compared. The longitudinal and transverse axes of the uterine cervix and uterine corpus were measured by transvaginal ultrasonography. The UCA was determined as the angle between two lines. One line was drawn between the internal and the external os, and the other was drawn through the internal cervical os and was parallel to the lower side of the front part of the uterine wall in the internal os. Demographic characteristics and uterocervical ultrasonographic measurements were compared between the two groups. RESULTS: Eighty participants, aged from 20 to 35 years, were enrolled (unexplained infertile [n = 30] and healthy fertile women [n = 50)]. The mean lengths of the uterine corpus longitudinal axis, uterine corpus transverse axis, and uterine cervix longitudinal axis were similar between the groups. The mean UCA was significantly higher in healthy fertile women (131.9 ± 22.9 degrees) than in women with unexplained infertility (114.2 ± 17.3 degrees). CONCLUSION: The present study shows that a narrow anterior UCA is associated with unexplained infertility.

The Effect of Iron Deficiency Anemia Early in the Third Trimester on Small for Gestational Age and Birth Weight: A Retrospective Cohort Study on Iron Deficiency Anemia and Fetal Weight.

AIM: The aim of the present study was to evaluate the relationship between iron deficiency anemia and small for gestational age (SGA) in early third trimester pregnancies. METHODS: A total of 4800 pregnant women who met the inclusion criteria were analyzed retrospectively. We included pregnant women who had iron deficiency anemia between 26+0 and 30+0 weeks of gestation and delivered singletons between 37+0 and 41+6 weeks of gestation. Patients were divided into four groups according to anemia level: (1) hemoglobin (Hb) < 7 mg/dl (n = 80), (2) Hb 7-9.9 mg/dl (n = 320), (3) Hb 10-10.9 mg/dl (n = 1300), and (4) Hb > 11 mg/dl (n = 3100, control group). The primary outcome of this study was the presence of SGA. RESULTS: The demographic and obstetric characteristics were similar among all the groups. Maternal age, BMI <30 kg/m2, nulliparity rates, and previous cesarean delivery rates were similar among groups. Ethnicity was significantly different in the severe and moderate anemia groups (<0.001). Mean fetal weight was 2900 ± 80 g in the severe anemia group, 3050 ± 100 g in the moderate anemia group, 3350 ± 310 g in the mild anemia group, and 3400 ± 310 g in the control group. Fetal weight was significantly lower in the severe and moderate anemia groups compared to the mild anemia and control groups (<0.001). The SGA rate was 18.7% in the severe anemia group, 12.1% in the moderate anemia group, 5.3% in the mild anemia group, and 4.9% in the control group. SGA was significantly higher in the severe and moderate anemia groups compared to the mild anemia and control groups (<0.001). CONCLUSION: The results of this study indicated that early third trimester severe and moderate iron deficiency anemia was associated with SGA. Iron deficiency anemia in pregnant women may lead to low birth weight.

The Effect of Immigration on Adverse Perinatal Outcomes: Analysis of Experiences at a Turkish Tertiary Hospital.

INTRODUCTION: In literature, it is well documented that migration is associated with adverse perinatal outcomes in many countries over the world. But in Turkey, health care providers and obstetricians had to face the effects of migration for the first time after civil war in Syria. Hence, this situation motivated us to conduct the current research in Turkey. Also we aimed to evaluate the effect of immigration on adverse perinatal outcomes, comparing the obstetric results of a native population and an immigrant population, and focusing on relevant indicators of perinatal health. METHODS: Information from the hospital database of pregnant women who had vaginal or cesarean delivery was evaluated. The patients were divided into two groups, native women and immigrant women, according to their ethnic origin. Adverse perinatal outcomes were compared between groups using multivariate regression models. Adjusted odds ratio (aOR) and 95% confidence interval (CI) were calculated. RESULTS: A total of 6311 patients were evaluated, of which 4271 were classified as native and 2040 were classified as immigrants. Mean hemoglobin level before delivery was significantly lower in the immigrant group. Preterm delivery (aOR: 1.41; 95% CI: 1.19-1.65), stillbirth (aOR: 1.88; 95% CI: 1.09-3.23), red blood cell transfusion requirement (aOR: 3.12; 95% CI: 2.02-3.98), unplanned birth rates before hospital arrival (aOR: 2.25; 95% CI: 1.53-3.31), and postpartum infection rates (aOR:2.12; 95% CI: 1.48-3.08) were significantly increased in the immigrant group compared with native group, even considering adjustment for potential confounders. CONCLUSION: The immigration may be an important and independent risk factor for some adverse maternal and neonatal outcomes.

How Well Do the Popular Ultrasonic Techniques Estimate Amniotic Fluid Volume and Diagnose Oligohydramnios, in Fact?

The aims of the study were to compare the different estimation methods for the diagnosis of oligohydramnios and to determine concordance between estimated amniotic fluid volume (AFV) measured by ultrasonography and actual AFV measured directly. Another purpose was to investigate the effect of oligohydramnios on neonatal outcome. This study was done at a tertiary care center. The participants were scheduled between 37 and 40 weeks for cesarean delivery. Estimated AFV was ultrasonographically assessed, and then actual AFV was directly measured during the cesarean delivery to compare the subjective method (SM), amniotic fluid index (AFI), single deepest pocket (SDP), and 2-diameter pocket. Totally, 138 patients were included in the present study. Of 35 (34%), 24 (21%), 12 (9.5%), and 10 (7.8%) were defined as oligohydramnios by the SM, AFI, SDP, and 2-diameter pocket, respectively. The number of patients with actual oligohydramnios was 35 (34%). Most authors suggest as a method use of the SDP more than the AFI, because of overmanagement through the AFI. However, this study, which was conducted using both nonprejudiced and criterion-standard methods, showed that the SM and AFI technique were more successful to estimate oligohydramnios than other methods. Also, adverse pregnancy outcome was not closely associated with isolated oligohydramnios.

Effect of vitamin D deficiency on the 75 g oral glucose tolerance test screening and insulin resistance.

Gestational diabetes mellitus (GDM), is the most common medical complications of pregnancy. This study aimed to clarify the effect of second-trimester vitamin D deficiency on the 75 g oral glucose tolerance test (OGTT) screening and insulin resistance. A total of 120 pregnant women with a singleton pregnancy at a gestational age of 26-28 weeks were analyzed. Participants were divided into two groups according to 25-hydroxyvitamin D levels; vitamin D deficiency, and control groups. For GDM scan, 75 g OGTT was preferred. GDM prevalence was 17.5% in vitamin D deficiency group and 13.75% in control group, there is no significant difference in GDM prevalence (p = 0.149). Fasting plasma glucose and 1-h plasma glucose levels were significantly higher in the vitamin D deficiency group than in the control group (p < .001 and p < .001, respectively). No significant differences were observed between 2-hour plasma glucose levels (p = .266). The HOMA-IR level was significantly higher in the vitamin D deficiency group than in the control group (p < .001). The findings of the present study suggested that vitamin D deficiency in the second trimester was inversely correlated with fasting and 1-h plasma glucose after 75 g glucose challenge test; also, low 25 OHD3 levels were associated with insulin resistance.

The Effect of Anterior Uterocervical Angle on Primary Dysmenorrhea and Disease Severity.

Background: Primary dysmenorrhea, defined as painful menstrual cramps originating in the uterus without underlying pathology, is a gynecological disease that affects quality of life and school success. Our goal was to determine the effect of anterior uterocervical angle on primary dysmenorrhea and disease severity. Methods: A total of 200 virgin adolescents, 16 to 20 years of age, were included in the study. The Andersch and Milsom scale was used to determine dysmenorrhea severity. Those with pathologies causing secondary dysmenorrhea were excluded from the study. Study subjects were grouped based on severity of pain. Demographic characteristics and uterocervical ultrasonographic measurements were compared among groups. Results: Of the 200 participants enrolled in the study, 50 were healthy controls and 150 had primary dysmenorrhea. Those with primary dysmenorrhea had a significant family history of primary dysmenorrhea compared with controls (P < 0.001). Age (P=0.668), body mass index (P=0.898), menarche age (P=0.915), and length of menstrual cycles (P=0.740) were similar in all groups. The uterine corpus longitudinal axis, uterine corpus transverse axis, and uterine cervix longitudinal axis were also similar (P=0.359, P=0.279, and P=0.369, resp.). The mean uterocervical angle was 146.8 ± 6.0 in controls and 143.3 ± 7.3 in those with mild pain with no significant difference between the groups. In those with moderate pain, the mean uterocervical angle was 121.2 ± 7.3 compared with 101 ± 9.2 in those with severe pain, which was a significant difference. Additionally, there was also a significant difference in the uterocervical angle among those with mild, moderate, and severe pain (P < 0.001). Conclusion: Our results indicate that a narrower anterior uterocervical angle is associated with primary dysmenorrhea and disease severity.

Cervical Local Immune Response for High-Risk Human Papillomavirus Infection: Involvement With Cervical Mucus SLPI Proteins.

PURPOSE: To evaluate cervical mucus secretory leukocyte protease inhibitor (SLPI) concentrations in patients with high-risk human papillomavirus (hrHPV) 16 or 18 positive and low-grade squamous intraepithelial lesions (LGSIL) or high-grade squamous intraepithelial lesions (HGSIL). METHOD: Patients with HPV 16 or 18 positive from 30 to 45 years of age whose cervical cancer screening results reported cytologically LGSIL or HGSIL were included in the study. In the control group, we included participants in the same age with cytology negative and HPV-negative healthy women. All cytological LGSIL or HGSIL results were histopathologically confirmed with colposcopic biopsy specimens. Finally, the study consisted of a total of 3 groups each containing 25 participants as follows: (1) Pap smear and HPV-negative control group, (2) HPV 16 or HPV 18 and LGSIL-positive participants, and (3) HPV 16 or 18 and HGSIL-positive participants. Cervical mucus SLPI levels were analyzed using the enzyme-linked immunosorbent assay method. RESULTS: The mean cervical mucus SLPI levels were 32.94 ng/mL (range: 23-41.29 ng/mL) in the hrHPV + LGSIL group, 29.40 ng/mL (range: 21.03-38.95 ng/mL) in the hrHPV + HGSIL, and 18.75 ng/mL (range: 13.58-29.24 ng/mL) in the healthy control group. Cervical mucus SLPI levels were found to be significantly higher in the hrHPV + LGSIL and hrHPV + HGSIL groups compared to the control group ( P < .001). CONCLUSIONS: The data from the present study indicate that SLPI seems to be one of the important immunomodulatory proteins that provide local immune response in cervical mucosa.

High Immune Expression of Progesterone-Induced Blocking Factor in Epithelial Ovarian Cancer.

BACKGROUND: Progesterone-induced blocking factor, which is released from maternal lymphocytes during pregnancy mediates the immune effect of progesterone. According to new reports, it is suggested that proliferating cells, such as human trophoblasts, mesenchymal stem cells, and malignant tumors, can excrete progesterone-induced blocking factor at high ratio to escape from maternal immunity. It is shown in recent studies that progesterone-induced blocking factor is overexpressed in many malignant tumors such as breast, cervical, lymphoma, and leukemia. There are no data about progesterone-induced blocking factor expression in ovarian cancer cells. Hence, it is aimed to determine the progesterone-induced blocking factor expression levels in epithelial ovarian cancer. METHODS: The study which was a retrospective cross-sectional study was conducted in a University Hospital. Twenty tissue specimens of patients with epithelial ovarian cancer and 20 tissue specimens of patients with healthy ovary were included in the study. Primary rabbit polyclonal anti- progesterone-induced blocking factor antibody was used to incubate the sections at a ratio of 1:300. RESULTS: When the tissue sections were compared based on immunostaining with progesterone-induced blocking factor, we detected high stromal progesterone-induced blocking factor expression in the epithelial ovarian cancer group as check against to the normal ovarian group ( P = .007). Similarly, we found high glandular progesterone-induced blocking factor expression in the epithelial ovarian cancer group as check against to the normal ovarian group ( P < .001). CONCLUSION: Proving the existence of progesterone-induced blocking factor expression in epithelial ovarian cancer cells may lead new visions or new studies for epithelial ovarian cancer immunotherapy. As a result, epithelial ovarian cancer cells have greater levels of expression of progesterone-induced blocking factor protein than normal ovarian tissue according to immunohistochemistry. Further research is needed to understand the clinical importance of this finding, to learn outcomes of high levels of progesterone-induced blocking factor, and to investigate its underlying mechanisms.

Serum Galectin 7 is Not Useful to Predict Abortion in the First Trimester.

OBJECTIVE: Galectins are animal lectins that bind to surface glycoproteins expressed at the fetal-maternal interface. The aim of this prospective case-control study was to investigate the possible relationship between levels of maternal serum galectin-7 and threatened abortion (TA) and to determine whether serum galectin-7 had any prognostic value. METHODS: This prospective study was conducted between August 2014 and February 2015. Included in the study were 31 consecutive pregnant women who were hospitalized for TA between 6 and 14 weeks of gestation and 33 healthy gestational age matched pregnant women without any symptoms of miscarriage. Serum galectin-7 levels were measured via ELISA. RESULTS: The mean serum galectin-7 levels of the two groups were not significantly different (31 TA patients: 2.84 ± 0.43 pg/mL, 33 controls: 2.785 ± 0.32 pg/mL, p = 0.543). Six pregnancies in the TA group resulted in abortion (19.4%). CONCLUSION: Serum galectin-7 was not useful for predicting prognosis in TA.

Perinatal outcomes in uncomplicated late preterm pregnancies with borderline oligohydramnios.

PURPOSE: The purpose of this study is to determine the adverse perinatal outcomes in uncomplicated late preterm pregnancies with borderline oligohydramnios. METHODS: A total of 430 pregnant women with an uncomplicated singleton pregnancy at a gestational age of 34 + 0-36 + 6 weeks were included. Borderline oligohydramnios was defined as an amniotic fluid index (AFI) of 5.1-8 cm, which was measured using the four-quadrant technique. Adverse perinatal outcomes were compared between the borderline and normal AFI groups. RESULTS: Approximately 107 of the 430 pregnant women were borderline AFI, and 323 were normal AFI. The demographic and obstetric characteristics were similar in both groups. Delivery <37 weeks, cesarean delivery for non-reassuring fetal heart-rate testing, meconium-stained amniotic fluid, Apgar 5 min <7, transient tachypnea of the newborn, respiratory distress syndrome, neonatal intensive care unit, and hyperbilirubinemia were not statistically different between the groups (p = .054, p = .134, p = .749, p = 0.858, p = .703, p = .320, p = .185, and p = .996, respectively). Although gestational age was full-term, induction of labor rates were significantly higher in the borderline AFI group (p = .040). In addition, fetal renal artery pulsatility index pulsatility index (PI) was significantly lower in the borderline AFI group than in the normal AFI group (p = .014). CONCLUSION: Our results indicated that borderline AFI was not a risk for adverse perinatal outcomes in uncomplicated, late preterm pregnancies.

The Efficacy of Dienogest in the Treatment of Simple Endometrial Hyperplasia without Atypia.

AIM: The aim of the study was to compare the effectiveness of dienogest (DIE), depo medroxyprogesterone 17-acetate (MPA), and micronized progesteron (MP) regimens for treatment of simple endometrial hyperplasia (EH) without atypia. METHODS: One hundred and twenty premenopausal patients aged between 35 and 55, with simple EH without atypia, were offered 3 types of progestins (MPA, MP, and DIE) and were randomized to one of them. After 6 months of treatment, patients were reevaluated. The efficacy of different progestins in treatment of EH was compared with regard to resolution and regression rates. We classified the terms of resolution and regression as "complete response" and persistence as "no response". RESULTS: A total of 99 patients continued the study (31 in MP, 35 in MPA, and 33 in the DIE group). None of the results of endometrial pathology were progressed to atypia or complex hyperplasia. The complete response resolution rate was 93.5% in the MP, 88.5% in the MPA, and 96.9% in the DIE group. The highest complete response rate was in the DIE group, although there was no statistically significant difference between groups (p = 0.39). The efficacy of progestins was similar between the groups. CONCLUSION: DIE is an effective and convenient method for thinning the endometrium.
