Thirty female Wistar pregnant rats were divided into five groups. Group A considered as control and received intraperitoneal saline 0.9% on 17th day of gestation or DG) and groups B and C treated with 20 mg/kg/day intravenous ceftriaxone and ceftazidime, respectively (DG: 18-20). Groups D and E received intraperitoneal E. coli and LPS on 17th DG respectively. Also, groups F and G received the same treatment as group D but they treated with the exact antibiotics mentioned for groups B and C (same dose and duration). Pregnancy outcomes as well as maternal sera levels of endotoxin, tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 were assessed using enzyme-linked immunosorbent assay. It was shown that group B had a higher IL-1β (P = 0.003) and TNF-α (P = 0.003) levels compared to the controls (CTC). Group C expressed a lower gestational duration (P = 0.007) as well as higher IL-6 (P = 0.025) and TNF-α (P < 0.001) levels CTC. Interestingly, both group B (P = 0.021) and C (P < 0.001) had a higher rate of endotoxin release CTC. Moreover, in group C, IL-6 (P < 0.0001 and r = -0.941) had a significant correlation with gestational duration. As the results showed, antibiotic administration in non-indication condition seems to be associated with significantly higher production of endotoxin and inflammatory cytokines which increase the risk of poor pregnancy outcomes.

This study aimed to investigate the important factors regarding the occurrence of PA, as well as outcomes and complications of Trans Abdominal Hysterectomy (TAH) in the patients with PA. Materials & Methods: The study was performed as an observational cross-sectional study. Between March 2011 and March 2017, 177 patients, known cases of PA that undergone TAH, were enrolled in our study. Extracted data include demographic characteristics, patient's medical history, surgical approach and complications, such as blood loss and urologic problems. Results: The average of maternal age and gestational age were 33.6±4.70 (range= 22-43) years and 34.6±3.16 weeks, respectively. Neither maternal age (P=0.652) nor BMI (P=0.659) had significant association with abnormal placentation. Previous history of dilation & curettage (D&C) was found in 34 patients that was not related to the occurrence of the PA (P=0.508).Twenty-one (11.9%) of the patients needed urological intervention that did not associated with placental position, skin and uterine incision (P=0.258, 0.410 and 0.219). There is no relation between amount of blood loss with gestational age (P=0.7) and number of C/S (P=0.4), gestational age (P=0.7), anesthesia (P=0.2), and curettage history (P=0.3). Conclusion: Our mortality and morbidity rate is much lower than reported ones, indicating the high-level ability, skill and knowledge of the surgeons.

Methods: The study was conducted as an observational cross-sectional study, including 25 pregnant women with gestational diabetes as the cases and 50 healthy pregnant women as the controls. The preload index, left and right side myocardial performance index (MPI), Interventricular septal hypertrophy, the left and right side cardiac output were assessed in all the patients. Results: The gestational ages were 31.65 ± 8.02 and 31.64 ± 5.37 weeks in case and control group respectively, without any significant difference. Both of the left and right ventricular MPI did not differ statistically between the case and controls. The cases had a greater Interventricular septal hypertrophy but the cardiac output was similar. The preload index was higher in the fetuses of the gestational diabetic mothers. Conclusions: In our study, the MPI did not show any difference between the fetuses of the gestational diabetic mothers and nondiabetic ones; but, fetuses of gestational diabetic mothers had a greater value of PLI, representing early diastolic function changes in right heart even before the overt heart failure occurred. This could be a sign of vasculopathy in gestational diabetic mothers.

Methods: This study was conducted as a prospective, randomized, open label, clinical trial evaluated 100 pregnant women who referred for prenatal visit, with 16-17 weeks of gestation from September 2014 through October 2015. The mothers were then randomly allocated into two groups: the vaginal progesterone group to receive 400mg Cyclogest vaginal suppositories (Actavis, UK limited, England) once daily, and the intramuscular progesterone group to receive weekly intramuscular injections of 250mg of 17-Hydroxyprogesterone Caproate (17-HPC) (Bayer Schering Pharma, Germany), starting from the 16th to the 35th weeks of pregnancy. demographics, medical and obstetrical history, sleeping disturbances, alteration in sexual desire, nausea/vomiting, serum levels of fasting blood sugar (FBS), high density lipoprotein (HDL), and low density lipoprotein (LDL) were evaluated, first and 8 weeks later. Results: 11 (11.2%) screened positive for psychosocial disorders; 25 (25.5%) had sleep disturbance, 11 (11.2%) had alteration in sexual desire, and 29 (29.6%) had nausea/vomiting upon enrolment. after two months of receiving daily vaginal progesterone there was a significant increase in the GHQ-28 score (p<0.001), and rates of positive screening for psychosocial disorders (p=0.001) in this group.

This prospective cohort study evaluated 400 gravida two pregnant women (200 with previous none medically indicated CD and 200 with previous normal vaginal deliveries (NVD)) who were referred for second trimester fetal anatomic survey. Uterine artery Doppler studies were performed in all participants who were then followed until delivery. Compared with women having prior NVD, women with prior CD had significantly higher rates of abnormal uterine artery pulsatility index (PI) (p < .001), and significantly more adverse pregnancy outcomes (p = .01). Among women with previous CD, all the measured adverse pregnancy outcomes occurred significantly more often in women with abnormal uterine artery Doppler indices (p...

Methods: This prospective, open-label, randomized clinical trial was conducted on 144 pregnant women with singleton pregnancy who had a cervical length ≤ 25 mm, at 18-22 gestational weeks (GW). Seventythree patients were assigned to receive 400 mg of daily vaginal progesterone (group A), and 73 to receive cervical pessary plus 400 mg of daily vaginal progesterone (group B), until the 37th GW. The patients were then followed until delivery. Results: The rates of preterm birth were 16.4% in group A and 19.7% in group B, which were not statistically different (P = 0.6). There were no statistically significant differences in the rates of preterm birth at <37, <34, <32, and ≤26 GW between participants randomized to each group (P = 0.55). The rates of low-birthweight delivery were 17.8% in group A, and 23.9% in group B, which were not statistically different (P = 0.36). The rates of premature rupture of membranes, chorioamnionitis, the requirement for neonatal intensive care unit admission, and fetal and neonatal deaths were similar between the two groups. Conclusion: In pregnancies with short cervix at mid-pregnancy, combination therapy of cervical pessary plus daily vaginal progesterone does not have any additional benefit over daily vaginal progesterone alone in reducing the rate of preterm birth and adverse pregnancy outcomes.

This prospective cohort study evaluated 1279 pregnant women who were referred for their first prenatal visit in 2012-2015. Mother's body mass index (BMI) was recorded before pregnancy, during the first visit and every 4 weeks until 28 gestational weeks. All mothers underwent GCT at 28 weeks and when 1 h glucose ≥140 mg/dL (≥7.8 mmol/L), they were referred for a 100 g fasting glucose 3 h glucose tolerance test. Obesity and being overweight prior to pregnancy were associated with 2.8-fold and 1.5-fold higher rates of developing GDM (p<0.001, p=0.04) and 1.9-fold and 1.8-fold higher rates of having false-positive GCT results (p<0.001). First-trimester excessive weight gain was significantly associated with false-positive GCT in women who were lean, overweight and obes...

Conclusions Early iron supplementation in mothers with PPD significantly improves the iron stores and causes a significant improvement in PPD with a 42.8 % improvement rate during 6 weeks. Continued PPD might be related to the lower postpartum ferritin levels in untreated mothers.

Cu... more Iodine-containing disinfectants are widely used for skin preparation before caesarean section. Current evidence suggests that maternal exposure to these disinfectants results in thyroid dysfunction in the newborns, but its extent is not known. The purpose of this study was to explain the quality of the effect of these disinfectants on the thyroid function of newborns. This cohort study was performed on all the healthy mothers with a term pregnancy who underwent caesarean section in the obstetrics emergency department of an educational hospital affiliated with Tehran University of Medical Sciences from December 2013 to December 2014. We divided this 12-month period into two consecutive 6 months. Povidone-iodine 10% (PVP-I) and chlorhexidine gluconate 4% (CHX) were used in the first and second 6 months, respectively, for skin preparation before caesarean section and also for umbilical cord disinfection. Cord blood thyroid stimulating hormone (TSH) and thyroxine (T4) were assayed by the ELISA method. We included 326 cases in this study, 153 in the PVP-I group and 173 in the CHX group. The incidence of cord blood TSH ≥10 mIU/L and T4 ≤7.3 µg/dL was significantly higher in the PVP-I than the CHX group. Cord blood TSH concentration showed a significant positive correlation with cord blood T4 concentration in the CHX group. Through selection of cases with cord blood T4 <13 µg/dL, we found a negative correlation between cord blood TSH and T4 concentration in the PVP-I group. It seems that PVP-I has the potential to cause false-positive screening-test results and increase recall rates, which should be evaluated in further studies.

Eight hundred sixteen preterm (born at &amp;amp;amp;lt;37 gestational weeks) neonates with no other morbidities who were born by cesarean section were evaluated. Immediately after delivery, UC-ABG analysis was performed and the neonates were followed. Preeclamptic women had lower umbilical cord blood (UCB) pH (7.2 4 ± 0.1 versus 7.2 7 ± 0.08, p = 0.008) and higher UCB base deficit (BD) (3.5 ± 3.7 versus 2.2 ± 3.4, p = 0.005) compared with controls. In the preeclamptic group, UCB metabolic acidosis (pH &amp;amp;amp;lt; 7.15 and B.D &amp;amp;amp;gt; 8) was not independently associated with neonatal morbidity or mortality, while in the control group UCB metabolic acidosis was independently associated with low 10-min Apgar (OR, 4.9; 95%CI 1.37-18.03), respiratory distress syndrome (OR, 2.37; 95%CI 1.05-6.17), intraventricular hemorrhage (OR, 3.01; 95%CI 1.13-7.99), and neonatal mortality (OR, 17.33; 95%CI 4.51-66.53). The preterm neonates born to preeclamptic mothers have lower UCB pH and higher BD. In these neonates, UCB acidosis is not independently associated with any adverse neonatal outcomes. In contrast, in the preterm neonates born to healthy mothers, UCB metabolic acidosis is independently associated with neonatal mortality and morbidity.

Methods: This prospective cohort study evaluated 1,595 pregnant women referred for prenatal visits. Maternal state/trait anxiety levels were measured, then quadruple screening was performed by measuring serum α-fetoprotein (AFP), β-human chorionic gonadotropin, inhibin A, and unconjugated estriol (UE3). After receiving the results, the state/trait anxiety was remeasured. Amniocentesis was performed for screening-positive mothers. Results: High prescreening maternal anxiety was associated with lower rates of elevated AFP (OR, 0.27; 95% CI, 0.1-0.74) and elevated inhibin A (OR, 0.38; 95% CI, 0.15-0.98). High maternal anxiety was associated with higher rates of decreased UE3 (OR, 1.8; 95% CI, 1.06-3.08). There were no significant associations between prescreening maternal anxiety and the final screening or amniocentesis results...

Here, we investigated the association between NT thickness and thyroid related hormones. NT thickness was measured with transabdominal ultrasound in 643 pregnant women between 11 and 13 weeks of gestation. Maternal thyroxine (T4), free thyroxine (fT4) and thyroid-stimulating hormone (TSH) were evaluated. Bivariate correlations were assessed and thyroid profile was subcategorized with regard to the calculated reference ranges. An inverse relation was found between serum levels of maternal T4 with NT thickness (r = -0.128, p = 0.001) and CRL (r = -0.168, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). TSH and hCG were also found to be correlated (Spearman&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s correlation coefficient = -0.092, p = 0.019). Prevalence of maternal hypothyroidism and subclinical hypothyroidism were 1.1% and 3.7%, respectively. Thyroid function tests are found to independently influence NT measurements in the first trimester. Assessment of hormones such as thyroxine could optimize the interpretation of screening tests for pathological conditions during pregnancy.

The primary outcome was the adverse pregnancy outcome. This randomized controlled trial was conducted in singleton pregnant women, who had unexplained AFP &amp;amp;amp;amp;amp;amp;amp;gt;2.5 MOM and gestational age between 15 and 18 weeks of gestation. They were assigned randomly to receive either aspirin (N = 65) or control (N = 68). UtA Doppler velocimetry studies were performed at the time of targeted ultrasonographic exam. Two groups were comparable regarding the maternal characteristics. The frequency of APO in aspirin and control groups were 26.1% versus 44.1% (p = 0.045), the frequency of preterm delivery before 34 weeks were 3.2% versus 22.0% in aspirin and control group, p = 0.001. Other outcomes were similar in both groups. The frequency of adverse outcomes in women with abnormal UtA Doppler was 39.1% in aspirin and 60.0% in control group, p = 0.556. Low-dose aspirin reduces APO and delivery before 34 weeks of gestation in pregnant women with unexplained elevated AFP.

Four-hundred sixty pregnant women completed the study, upon enrollment Vaginal pH was measured for all women, maternal and umbilical sera were obtained for determining C-reactive protein (CRP) and uric acid levels. Umbilical blood was tested for gas parameters, 1 and 5 min Apgar scores, the need for neonatal resuscitation and neonatal intensive care unit (NICU) admission were recorded. Elevated vaginal pH was significantly associated with preterm birth (odds ratio (OR), 2.23; 95% confidence interval (CI), 1.04-4.76), emergency cesarean section (OR 2.57; 95% CI 1.32-5), neonatal resuscitation in the delivery room (OR 2.85; 95% CI 1.1-7.38), elevated cord base deficit (OR 8.01; 95% CI 1.61-39.81), low cord bicarbonate (OR 4.16, 95% CI 1.33-12.92) and NICU admission (OR 2.02; 95% CI 1.12-3.66). Increased vaginal pH was also significantly associated with maternal leukocytosis, hyperuricemia and elevated CRP levels in maternal and umbilical sera. Elevated vaginal pH in the absence of current vaginal infection still constitutes a risk for adverse pregnancy outcome which is mediated by systemic inflammatory response.

This randomized clinical trial was performed as an open-label study. 310 symptomatic patients with BV were recruited. Diagnosis of BV was through Amsel criteria. The patients were randomly assigned to receive either probiotic yoghurt (100 g twice a day/week) or orally administered clindamycin (300 mg twice a day/week). Ten patients in probiotic group and 9 subjects in clindamycin group had symptom recurrence (p &amp;amp;amp;amp;amp;amp;amp;gt; 0.05). 132 patients in probiotic group and 105 subjects in clindamycin group had pH decrease (p &amp;amp;amp;amp;amp;amp;amp;lt; 0.0001). 140 patients in probiotic group and 141 subjects in clindamycin group had complete symptomatic cure (p &amp;amp;amp;amp;amp;amp;amp;gt; 0.05). Twelve patients in probiotic group and seven subjects in clindamycin group had preterm birth. Nine women in probiotic group and five subjects in clindamycin group had PROM (p &amp;amp;amp;amp;amp;amp;amp;gt; 0.05). According to the obtained results, it may be concluded that probiotics would have a good efficacy in the treatment of bacterial vaginosis in pregnancy leading to decreased burden of subsequent preterm birth.

One hundred and sixty pregnant women with clinical symptoms of threatened abortion before the 20th week of pregnancy were randomly assigned to receive vaginal progesterone or placebo. Cervical fluids were collected and endocervical concentrations of different cytokines (IFN␥, TNF␣, IL-8, IL-10 and IL-12) were analyzed before and one week after progesterone or placebo treatment. A significant decrease in IFN␥ and increase in IL-10 in endocervical fluid was seen when the values were compared before and after progesterone treatment. However, there were no significant differences in pregnancy outcomes between the placebo and progesterone groups. We conclude that despite the failure of vaginal progesterone treatment to improve pregnancy outcomes, progesterone can induce a shift in the concentration of cytokines in endocervical secretions.

This prospective cohort study evaluated 400 gravida two pregnant women (200 with previous none medically indicated CD and 200 with previous normal vaginal deliveries (NVD)) who were referred for second trimester fetal anatomic survey. Uterine artery Doppler studies were performed in all participants who were then followed until delivery. Compared with women having prior NVD, women with prior CD had significantly higher rates of abnormal uterine artery pulsatility index (PI) (p < .001), and significantly more adverse pregnancy outcomes (p = .01). Among women with previous CD, all the measured adverse pregnancy outcomes occurred significantly more often in women with abnormal uterine artery Doppler indices (p...

Methods: This prospective, open-label, randomized clinical trial was conducted on 144 pregnant women with singleton pregnancy who had a cervical length ≤ 25 mm, at 18-22 gestational weeks (GW). Seventythree patients were assigned to receive 400 mg of daily vaginal progesterone (group A), and 73 to receive cervical pessary plus 400 mg of daily vaginal progesterone (group B), until the 37th GW. The patients were then followed until delivery. Results: The rates of preterm birth were 16.4% in group A and 19.7% in group B, which were not statistically different (P = 0.6). There were no statistically significant differences in the rates of preterm birth at <37, <34, <32, and ≤26 GW between participants randomized to each group (P = 0.55). The rates of low-birthweight delivery were 17.8% in group A, and 23.9% in group B, which were not statistically different (P = 0.36). The rates of premature rupture of membranes, chorioamnionitis, the requirement for neonatal intensive care unit admission, and fetal and neonatal deaths were similar between the two groups. Conclusion: In pregnancies with short cervix at mid-pregnancy, combination therapy of cervical pessary plus daily vaginal progesterone does not have any additional benefit over daily vaginal progesterone alone in reducing the rate of preterm birth and adverse pregnancy outcomes.

This prospective cohort study evaluated 1279 pregnant women who were referred for their first prenatal visit in 2012-2015. Mother's body mass index (BMI) was recorded before pregnancy, during the first visit and every 4 weeks until 28 gestational weeks. All mothers underwent GCT at 28 weeks and when 1 h glucose ≥140 mg/dL (≥7.8 mmol/L), they were referred for a 100 g fasting glucose 3 h glucose tolerance test. Obesity and being overweight prior to pregnancy were associated with 2.8-fold and 1.5-fold higher rates of developing GDM (p<0.001, p=0.04) and 1.9-fold and 1.8-fold higher rates of having false-positive GCT results (p<0.001). First-trimester excessive weight gain was significantly associated with false-positive GCT in women who were lean, overweight and obes...

Conclusions Early iron supplementation in mothers with PPD significantly improves the iron stores and causes a significant improvement in PPD with a 42.8 % improvement rate during 6 weeks. Continued PPD might be related to the lower postpartum ferritin levels in untreated mothers.

Cu... more Iodine-containing disinfectants are widely used for skin preparation before caesarean section. Current evidence suggests that maternal exposure to these disinfectants results in thyroid dysfunction in the newborns, but its extent is not known. The purpose of this study was to explain the quality of the effect of these disinfectants on the thyroid function of newborns. This cohort study was performed on all the healthy mothers with a term pregnancy who underwent caesarean section in the obstetrics emergency department of an educational hospital affiliated with Tehran University of Medical Sciences from December 2013 to December 2014. We divided this 12-month period into two consecutive 6 months. Povidone-iodine 10% (PVP-I) and chlorhexidine gluconate 4% (CHX) were used in the first and second 6 months, respectively, for skin preparation before caesarean section and also for umbilical cord disinfection. Cord blood thyroid stimulating hormone (TSH) and thyroxine (T4) were assayed by the ELISA method. We included 326 cases in this study, 153 in the PVP-I group and 173 in the CHX group. The incidence of cord blood TSH ≥10 mIU/L and T4 ≤7.3 µg/dL was significantly higher in the PVP-I than the CHX group. Cord blood TSH concentration showed a significant positive correlation with cord blood T4 concentration in the CHX group. Through selection of cases with cord blood T4 <13 µg/dL, we found a negative correlation between cord blood TSH and T4 concentration in the PVP-I group. It seems that PVP-I has the potential to cause false-positive screening-test results and increase recall rates, which should be evaluated in further studies.

Eight hundred sixteen preterm (born at &amp;amp;amp;lt;37 gestational weeks) neonates with no other morbidities who were born by cesarean section were evaluated. Immediately after delivery, UC-ABG analysis was performed and the neonates were followed. Preeclamptic women had lower umbilical cord blood (UCB) pH (7.2 4 ± 0.1 versus 7.2 7 ± 0.08, p = 0.008) and higher UCB base deficit (BD) (3.5 ± 3.7 versus 2.2 ± 3.4, p = 0.005) compared with controls. In the preeclamptic group, UCB metabolic acidosis (pH &amp;amp;amp;lt; 7.15 and B.D &amp;amp;amp;gt; 8) was not independently associated with neonatal morbidity or mortality, while in the control group UCB metabolic acidosis was independently associated with low 10-min Apgar (OR, 4.9; 95%CI 1.37-18.03), respiratory distress syndrome (OR, 2.37; 95%CI 1.05-6.17), intraventricular hemorrhage (OR, 3.01; 95%CI 1.13-7.99), and neonatal mortality (OR, 17.33; 95%CI 4.51-66.53). The preterm neonates born to preeclamptic mothers have lower UCB pH and higher BD. In these neonates, UCB acidosis is not independently associated with any adverse neonatal outcomes. In contrast, in the preterm neonates born to healthy mothers, UCB metabolic acidosis is independently associated with neonatal mortality and morbidity.

Methods: This prospective cohort study evaluated 1,595 pregnant women referred for prenatal visits. Maternal state/trait anxiety levels were measured, then quadruple screening was performed by measuring serum α-fetoprotein (AFP), β-human chorionic gonadotropin, inhibin A, and unconjugated estriol (UE3). After receiving the results, the state/trait anxiety was remeasured. Amniocentesis was performed for screening-positive mothers. Results: High prescreening maternal anxiety was associated with lower rates of elevated AFP (OR, 0.27; 95% CI, 0.1-0.74) and elevated inhibin A (OR, 0.38; 95% CI, 0.15-0.98). High maternal anxiety was associated with higher rates of decreased UE3 (OR, 1.8; 95% CI, 1.06-3.08). There were no significant associations between prescreening maternal anxiety and the final screening or amniocentesis results...

Here, we investigated the association between NT thickness and thyroid related hormones. NT thickness was measured with transabdominal ultrasound in 643 pregnant women between 11 and 13 weeks of gestation. Maternal thyroxine (T4), free thyroxine (fT4) and thyroid-stimulating hormone (TSH) were evaluated. Bivariate correlations were assessed and thyroid profile was subcategorized with regard to the calculated reference ranges. An inverse relation was found between serum levels of maternal T4 with NT thickness (r = -0.128, p = 0.001) and CRL (r = -0.168, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). TSH and hCG were also found to be correlated (Spearman&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s correlation coefficient = -0.092, p = 0.019). Prevalence of maternal hypothyroidism and subclinical hypothyroidism were 1.1% and 3.7%, respectively. Thyroid function tests are found to independently influence NT measurements in the first trimester. Assessment of hormones such as thyroxine could optimize the interpretation of screening tests for pathological conditions during pregnancy.

The primary outcome was the adverse pregnancy outcome. This randomized controlled trial was conducted in singleton pregnant women, who had unexplained AFP &amp;amp;amp;amp;amp;amp;amp;gt;2.5 MOM and gestational age between 15 and 18 weeks of gestation. They were assigned randomly to receive either aspirin (N = 65) or control (N = 68). UtA Doppler velocimetry studies were performed at the time of targeted ultrasonographic exam. Two groups were comparable regarding the maternal characteristics. The frequency of APO in aspirin and control groups were 26.1% versus 44.1% (p = 0.045), the frequency of preterm delivery before 34 weeks were 3.2% versus 22.0% in aspirin and control group, p = 0.001. Other outcomes were similar in both groups. The frequency of adverse outcomes in women with abnormal UtA Doppler was 39.1% in aspirin and 60.0% in control group, p = 0.556. Low-dose aspirin reduces APO and delivery before 34 weeks of gestation in pregnant women with unexplained elevated AFP.

Four-hundred sixty pregnant women completed the study, upon enrollment Vaginal pH was measured for all women, maternal and umbilical sera were obtained for determining C-reactive protein (CRP) and uric acid levels. Umbilical blood was tested for gas parameters, 1 and 5 min Apgar scores, the need for neonatal resuscitation and neonatal intensive care unit (NICU) admission were recorded. Elevated vaginal pH was significantly associated with preterm birth (odds ratio (OR), 2.23; 95% confidence interval (CI), 1.04-4.76), emergency cesarean section (OR 2.57; 95% CI 1.32-5), neonatal resuscitation in the delivery room (OR 2.85; 95% CI 1.1-7.38), elevated cord base deficit (OR 8.01; 95% CI 1.61-39.81), low cord bicarbonate (OR 4.16, 95% CI 1.33-12.92) and NICU admission (OR 2.02; 95% CI 1.12-3.66). Increased vaginal pH was also significantly associated with maternal leukocytosis, hyperuricemia and elevated CRP levels in maternal and umbilical sera. Elevated vaginal pH in the absence of current vaginal infection still constitutes a risk for adverse pregnancy outcome which is mediated by systemic inflammatory response.

This randomized clinical trial was performed as an open-label study. 310 symptomatic patients with BV were recruited. Diagnosis of BV was through Amsel criteria. The patients were randomly assigned to receive either probiotic yoghurt (100 g twice a day/week) or orally administered clindamycin (300 mg twice a day/week). Ten patients in probiotic group and 9 subjects in clindamycin group had symptom recurrence (p &amp;amp;amp;amp;amp;amp;amp;gt; 0.05). 132 patients in probiotic group and 105 subjects in clindamycin group had pH decrease (p &amp;amp;amp;amp;amp;amp;amp;lt; 0.0001). 140 patients in probiotic group and 141 subjects in clindamycin group had complete symptomatic cure (p &amp;amp;amp;amp;amp;amp;amp;gt; 0.05). Twelve patients in probiotic group and seven subjects in clindamycin group had preterm birth. Nine women in probiotic group and five subjects in clindamycin group had PROM (p &amp;amp;amp;amp;amp;amp;amp;gt; 0.05). According to the obtained results, it may be concluded that probiotics would have a good efficacy in the treatment of bacterial vaginosis in pregnancy leading to decreased burden of subsequent preterm birth.

One hundred and sixty pregnant women with clinical symptoms of threatened abortion before the 20th week of pregnancy were randomly assigned to receive vaginal progesterone or placebo. Cervical fluids were collected and endocervical concentrations of different cytokines (IFN␥, TNF␣, IL-8, IL-10 and IL-12) were analyzed before and one week after progesterone or placebo treatment. A significant decrease in IFN␥ and increase in IL-10 in endocervical fluid was seen when the values were compared before and after progesterone treatment. However, there were no significant differences in pregnancy outcomes between the placebo and progesterone groups. We conclude that despite the failure of vaginal progesterone treatment to improve pregnancy outcomes, progesterone can induce a shift in the concentration of cytokines in endocervical secretions.
