The effect of glucose tolerance test on fetoplacental circulation.

OBJECTIVE: Acute hyperglycemia affects the fetoplacental circulation. This study aims to investigate the possible effect of acute hyperglycemia induced by 50 g oral glucose tolerance test (OGTT) on fetoplacental circulation in women between 24 and 28 weeks of gestation. MATERIALS AND METHODS: Between January 2019 and April 2019, a total of 29 women who were between 24 and 28 weeks of gestation with a singleton gestation and were in low-risk group were included in this prospective study. All patients underwent fetal biometric measurements using ultrasonography (USG) and were administered 50 g OGTT. Before and 1 h after the test, Doppler USG was used to measure uterine artery, umbilical artery (UA), middle cerebral artery (MCA), pulsatility index (PI), resistance index (RI), and systolic/diastolic (S/D) ratio. The cerebroplacental ratio (CPR) was calculated as the ratio of the MCA-PI/UA-PI. RESULTS: There was a decline in the MCA-RI (p = 0.008) and UA-PI (p = 0.021) at 1 h after the administration of 50 g OGTT. Z-scores of the mean UA-PI, MCA-PI, and CPR were calculated and a statistically significant increase in the Z-scores of the mean UA-PI was observed (p = 0.028). CONCLUSION: Our study results show that acute hyperglycemia induced by OGTT significantly increases the Z-scores of the UA-PI, affecting the fetoplacental circulation.

Antibiotic exposure during pregnancy and childhood asthma: a national birth cohort study investigating timing of exposure and mode of delivery.

OBJECTIVE: To investigate whether antibiotic exposure during pregnancy was associated with childhood asthma and if this relationship was conditional on timing of exposure and mode of delivery. DESIGN: A cohort study using multivariable logistic regression models adjusting for a priori defined confounders. Pregnant women were recruited from 1996 to 2002. SETTING: The Danish National Birth Cohort. PATIENTS: Of the 96 832 children in the cohort, 32 651 children were included in the study population. MAIN OUTCOME MEASURE: Parent-reported childhood asthma at 11 years. RESULTS: A total of 5522 (17%) children were born to mothers exposed to antibiotics during pregnancy. In adjusted analyses, children born to exposed mothers had higher odds of asthma (OR 1.14, 95% CI 1.05 to 1.24). There was no association with antibiotic exposure in the first trimester (OR 1.02, 95% CI 0.83 to 1.26), but higher odds were observed for antibiotic exposure in the second to third trimester (OR 1.17, 95% CI 1.06 to 1.28), compared with unexposed children. The overall association between antibiotics during pregnancy and childhood asthma was only observed in vaginally born children (OR 1.17, 95% CI 1.07 to 1.28) but not in caesarean section born children (planned caesarean section: OR 0.95, 95% CI 0.66 to 1.37; caesarean emergency: OR 0.96, 95% CI 0.73 to 1.28). In exposed vaginally born children, the odds for childhood asthma requiring treatment during the preceding year were 34% higher (OR 1.34, 95% CI 1.21 to 1.49), compared with unexposed vaginally born children. CONCLUSIONS: Antibiotic exposure in mid-to-late pregnancy is associated with higher odds of childhood asthma in vaginally born children. Mode of delivery may modify the association.

The safety of early pregnancy exposure to granisetron.

OBJECTIVE: Current guidelines suggest that granisetron is an optional treatment for nausea and vomiting in pregnancy (NVP) despite lack of evidence to support fetal safety. We aimed to determine the association between early pregnancy exposure to granisetron and fetal/neonatal outcomes. DESIGN: Medical records of patients treated for NVP during the first and second trimester between June 2013 to September 2015 were reviewed. Patients were asked to participate in the study by answering a detailed questionnaire regarding newborn's health and complementary data. Pregnancy outcomes of patients exposed to granisetron were compared with those of patients who were not exposed to granisetron. RESULTS: 100 Granisetron exposed pregnancies were compared with 108 granisetron unexposed pregnancies. Exposure to granisetron occurred in the first trimester in 88 patients (94 fetuses). Maternal characteristics, history of anomalies in first degree relatives, co-exposure to other substances and extent of prenatal sonographic surveillance were comparable between both groups. Miscarriage rate was significantly lower among granisetron exposed patients compared to controls (0 vs 5.5 %, respectively, p = 0.03). Three major malformations were identified prenatally or postnatally in each of the groups (2.77 % Vs 2.83 %, p = 1). The rate of major malformations was similar between exposed and unexposed fetuses even after excluding second trimester exposure (3.2 % vs. 2.83 %, respectively p = 1). Mean gestational age at delivery, mean newborn weight and incidence of small for gestation age, were not significantly different between the groups. CONCLUSION: Granisetron exposure was not associated with increased risk for minor or major fetal anomalies. This study provides preliminary reassurance regarding the safety of in-utero exposure to granisetron.

A randomized controlled trial of folic acid intervention in pregnancy highlights a putative methylation-regulated control element at ZFP57.

BACKGROUND: Maternal blood folate concentrations during pregnancy have been previously linked with DNA methylation patterns, but this has been done predominantly through observational studies. We showed recently in an epigenetic analysis of the first randomized controlled trial (RCT) of folic acid supplementation specifically in the second and third trimesters (the EpiFASSTT trial) that methylation at some imprinted genes was altered in cord blood samples in response to treatment. Here, we report on epigenome-wide screening using the Illumina EPIC array (~ 850,000 sites) in these same samples (n = 86). RESULTS: The top-ranked differentially methylated promoter region (DMR) showed a gain in methylation with folic acid (FA) and was located upstream of the imprint regulator ZFP57. Differences in methylation in cord blood between placebo and folic acid treatment groups at this DMR were verified using pyrosequencing. The DMR also gains methylation in maternal blood in response to FA supplementation. We also found evidence of differential methylation at this region in an independent RCT cohort, the AFAST trial. By altering methylation at this region in two model systems in vitro, we further demonstrated that it was associated with ZFP57 transcription levels. CONCLUSIONS: These results strengthen the link between folic acid supplementation during later pregnancy and epigenetic changes and identify a novel mechanism for regulation of ZFP57. This trial was registered 15 May 2013 at www.isrctn.com as ISRCTN19917787.

Photoperiod during maternal pregnancy and lifetime depression in offspring.

Experimental studies indicate that perinatal light exposure has enduring effects on affective behaviors in rodents; however, insufficient research has explored this hypothesis in humans. We examined photoperiod (i.e., day length) metrics during maternal pregnancy in relation to lifetime depression in the longitudinal Nurses' Health Study (NHS) and NHS II. 160,723 participants reported birth date and birth state (used to derive daily photoperiod based on published mathematical equations), and clinician-diagnosed depression and antidepressant use throughout adulthood. Logistic regression was used to estimate odds ratios (OR) (and 95% confidence intervals [CI]) for depression (defined as clinician diagnosis and antidepressant use) across quintiles of two exposures during maternal pregnancy: 1) total photoperiod (total number of daylight hours) and 2) differences between minimum/maximum photoperiod; each trimester of pregnancy was examined separately. Total photoperiod during maternal pregnancy was not associated with depression overall or by trimester of pregnancy. However, larger differences between minimum/maximum photoperiod during maternal pregnancy were related to lower odds of depression (multivariable [MV]-adjusted OR: 0.86, 95% CI: 0.83, 0.90 comparing extreme quintiles of exposure; p-trend<0.0001); this association appeared specific to the second trimester of pregnancy (MV-adjusted p-trends = 0.03, <0.0001, and 0.3 across the three trimesters, respectively). In addition, birth at higher latitude (where larger differences in minimum/maximum photoperiod exist) was associated with a significant reduction in the lifetime risk of depression. These findings are consistent with an emerging hypothesis in which perinatal light exposure may influence risk of depression, and they might be understood through the conceptual framework of adaptive developmental plasticity.

Pregnancy in Patients With Chronic Myeloid Leukemia.

Estimates suggest that nearly 30% of patients diagnosed with chronic myeloid leukemia (CML) are aged <49 years, with approximately half being women. For many of these women, childbearing concerns are a major factor as they initiate treatment with tyrosine kinase inhibitors, which are known to be teratogenic. During her presentation at the NCCN 23rd Annual Conference, Dr. Berman identified the challenges in helping women undergoing treatment for CML who want to have children, and emphasized the importance of an individualized and multidisciplinary approach to management. In addition, she encouraged NCCN to create a pregnancy registry of this patient population to enable clinicians to collect firm data to guide clinical decision-making.

Adjuvant administration of 17-α-hydroxy-progesterone caproate in women with three or more second trimester pregnancy losses undergoing cervical cerclage is no more effective than cerclage alone.

OBJECTIVE: To investigate the role of adjuvant 17-α-hydroxy-progesterone caproate (17OHP-C) in reducing the risk of preterm delivery <34 weeks and adverse perinatal outcomes in women with ≥3 second trimester pregnancy losses attributed to cervical insufficiency undergoing prophylactic cerclage. MATERIAL AND METHODS: Retrospective cohort study of women with prophylactic cerclage placed between 2006 and 2014 divided into a cohort of (i) those receiving adjuvant 17OHP-C (n=43), and (ii) controls with cerclage alone (n=59). RESULTS: Demographic characteristics were comparable in both groups. There was no significant difference in gestational age at delivery between the cerclage-17OHP-C group (33.4±5.6 weeks) and the cerclage-alone group (34.4±4.6 weeks); P=0.33. We noted a non-significant increase for deliveries <34 weeks in the cerclage-17OHP-C group (44.2%) compared to controls (28.8%) which remained non-significant after adjusting for confounders; P=0.46. There was no statistically significant difference in the rate of delivery <37, 32, 28 and 24 weeks. Adverse neonatal outcomes were comparable in both groups (cerclage-17OHP-C 48.8% vs. cerclage-alone 39%); P=0.43. CONCLUSION: Intramuscular 17OHP-C in combination with prophylactic cerclage in women with cervical insufficiency and ≥3 second trimester pregnancy losses had no synergistic effect in reducing the rate of recurrent preterm birth or improving perinatal outcomes.

EARLY gestational exposure to isoflurane causes persistent cell loss in the dentate gyrus of adult male rats.

BACKGROUND: Our previous research showed that 4 h of maternal anesthesia with isoflurane during early gestation in pregnant rats leads to a deficit in spatial memory of adult male offspring. Because spatial memory is predominantly a hippocampally-mediated task, we asked the question if early gestational exposure to isoflurane affects development of the hippocampus in the offspring. FINDINGS: Previously behaviorally characterized adult male rats that were exposed to isoflurane during second trimester were sacrificed at 4 months of age (N = 10 and 13, control and isoflurane groups, respectively) for quantitative histology of hippocampal subregions. Sections were stained with cresyl violet and the total number of cells in the granular layer of the dentate gyrus and the pyramidal cell layer in the CA1 region were determined by a blinded observer using unbiased stereological principles and the optical fractionator method. Data were analyzed using Student's t test; P < 0.05 was accorded statistical significance. Stereological examination revealed 9% fewer cells in the granular layer of the dentate gyrus of isoflurane-exposed adult rats compared to controls (1,002,122 ± 84,870 vs. 1,091,829 ± 65,791, respectively; Mean ± S.D, *P = 0.01). In contrast, there were no changes in the cell number in the CA1 region, nor were there changes in the volumes of both regions. CONCLUSIONS: Our results show that maternal isoflurane anesthesia in rodents causes region-specific cell loss in the hippocampus of adult male offspring. These changes may, in part, account for the behavioral deficits reported in adult rats exposed to isoflurane in utero.

Taxanes in combination with platinum derivatives for the treatment of ovarian cancer during pregnancy: A literature review
.

Ovarian cancer is one of the most common types of solid carcinoma diagnosed during pregnancy. Taxane plus a platinum derivative is a combination therapy that is predominantly used in the treatment of ovarian cancer in non-pregnant women. Pregnancy adds various complexities to a course of treatment. In pregnant patients diagnosed with cancer during the first trimester, the risks of fetal malformations and fetal loss increase following the administration of cytotoxic drugs, and this is higher with multi-agent vs. single-agent chemotherapy (~ 25 vs. 10%). Exposure during the second and third trimester has little influence on teratogenic effects but increases the risk of intrauterine growth retardation, prematurity, low birth weight, and bone marrow toxicity. The present study aimed to review the maternal and fetal safety of treatment with taxane plus platinum derivatives for ovarian cancer during pregnancy. Relevant literature was retrieved from the Embase and PubMed databases using the search terms "ovarian cancer", "pregnancy", "taxane", "paclitaxel", "docetaxel", "platinum", "cisplatin", and "carboplatin". All available data up until September 2016 was synthesized, with no language restrictions. A total of 11 articles (including 13 pregnancies and 14 newborns) were retrieved that reported on the use of standard-dose taxane and platinum chemotherapy, including 9 cases treated with paclitaxel and carboplatin, 3 cases treated with paclitaxel and cisplatin, and 1 case treated with docetaxel and cisplatin. In 13 of the 14 (92.9%) births included, a healthy neonate was born, with follow-up ranging from 2 to 160 months. The average weight of the neonates at the time of delivery was 2,442.1 g. In 7 of 9 the case reports that provided survival data, the mother was alive and disease-free at the end of follow-up (ranging from 2 to 40 months). In conclusion, combination therapy with taxanes and a platinum derivative may play a significant role in the management of pregnant patients with ovarian cancer during the second and third trimester. Exposure to this combination of agents during the second and third trimester does not appear to have a significant bearing on fetal mortality and abortion.

Maternal Continuing Folic Acid Supplementation after the First Trimester of Pregnancy Increased the Risk of Large-for-Gestational-Age Birth: A Population-Based Birth Cohort Study.

Supplementation with folic acid (FA) was proven to prevent neural tube defects (NTDs) and was recommended worldwide before and during early pregnancy. However, much less is known regarding the role of FA after the 12th gestational week (GW). This study aimed to investigate the related effects of continued FA supplementation after the first trimester of pregnancy on fetal growth. The study subjects came from the Ma'anshan-Anhui Birth Cohort Study (MABC) that recruited 3474 pregnant women from the city of Ma'anshan in Anhui Province in China during the period of May 2013 to September 2014. The information on use of vitamin and mineral supplements was recorded in different periods (the first/second/third trimester of pregnancy). Small-for-gestational-age (SGA) births were live-born infants that were <10th percentile of birth weight, and large-for-gestational-age (LGA) births were live-born infants that were ≥90th percentile of birth weight according to nomograms based on gender and gestational age from the latest standards. We used multivariable logistic regression to evaluate the effects of FA supplement consumption in the second/third trimester of pregnancy on the risk of LGA and SGA. In addition, propensity score analysis was also performed to examine the effects. In this prospective birth cohort study conducted in Chinese women who had taken FA in the first trimester of pregnancy, we found that continued FA supplementation with 400 micrograms/day in the second and third trimesters of pregnancy significantly increased the risk of LGA (RR = 1.98 (1.29, 3.04)). This relation was strong or monotonic after adjusting for maternal age, newborn's gender, maternal pre-pregnancy BMI, maternal education level, smoking, alcohol consumption and calcium supplementation. We did not observe that continuing FA supplementation after the first trimester of pregnancy remarkably decreased the risk of SGA. The propensity score analysis showed similar results. To confirm these findings, additional investigations or trials with a large sample and the tracking of folate status throughout pregnancy are recommended.

Tailored anti-TNF therapy during pregnancy in patients with IBD: maternal and fetal safety.

OBJECTIVE: Antitumour necrosis factor (TNF) during pregnancy in patients with IBD is related to high fetal anti-TNF levels. We evaluated maternal and child safety on discontinuing anti-TNF in the second trimester of pregnancy. DESIGN: Two groups of women with IBD were prospectively followed-up during pregnancy: women in sustained remission stopped anti-TNF before week 25 (stop group) and the remaining group continued anti-TNF beyond week 30 (continue group). Maternal, birth and 1-year child outcomes were compared with children of non-IBD women. RESULTS: Overall, 106 patients with 83 completed pregnancies were included. Relapse rate after week 22 did not differ between the stop (n=51) and continue (n=32) groups (5 (9.8%) versus 5 (15.6%), p=0.14). There was no difference in allergic reactions (p=1.00) or loss of response (p=1.00) postpartum between the two groups. Birth outcomes were comparable. Infants from both groups had lower birth weight (p=0.001), shorter gestational term (p=0.0001), were more often delivered via caesarean section (p=0.0001) and were less often breastfed (p=0.0001) compared with infants from non-IBD controls. Growth, infection rate, allergies, eczema and adverse reactions to vaccines were comparable across the stop and the continue groups as well as the children of anti-TNF-exposed and non-IBD women at 1 year. CONCLUSIONS: To limit anti-TNF exposure in utero, anti-TNF can be stopped safely in the second trimester in women with IBD in sustained remission. In patients not in sustained remission, anti-TNF may be continued without clear additional risks to the fetus. We observed excellent 1-year child outcomes compared with children from non-IBD controls.

Intravenous carbetocin shot is superior to oxytocin infusion for placental delivery in second trimester abortion: a pilot randomized controlled trial.

OBJECTIVE: To study the efficacy of 100 µg intravenous shot of carbetocin compared to 20 IU oxytocin intravenous infusion to prevent placental retention in second trimester medical termination of pregnancy. METHODS: A double-blinded randomized controlled trial was conducted at Ain Shams University Maternity Hospital from 1 April 2013 to 30 November 2013. A total of 132 women between 14 and 24 weeks gestation indicated for termination were randomized to receive either 20 IU oxytocin infusion (n = 66) or 100 µg carbetocin shot (n = 66) after fetal expulsion. Patients were observed for time elapsed between fetal and placental expulsion, presence of placental retention and blood loss. RESULTS: Third stage was 33.4 ± 20.4 min in oxytocin group & 23.1 ± 16.8 min in carbetocin group (p = 0.002). Eight patients (12.1%) in oxytocin group had complete placental retention versus two patients (3.0%) in carbetocin group (p = 0.05). Eight patients (13.8%) received oxytocin had remnants of placenta compared to four patients (6.2%) received carbetocin (p = 0.04). Sixteen patients (24.2%) received oxytocin and six patients (9%) received carbetocin needed surgical curettage (p = 0.04). Third stage blood loss was 87.2 ± 33.7 ml in carbetocin and 206.9 ± 35.2 ml in oxytocin groups (p = 0.001). CONCLUSION: Carbetocin is superior to oxytocin infusion for management of placental delivery in second trimester abortion.

Misoprostol 1 to 3 h preprocedure vs. overnight osmotic dilators prior to early second-trimester surgical abortion.

OBJECTIVES: We sought to compare the effectiveness of at least 1 h of 400 mcg of buccal misoprostol to overnight osmotic dilators for early second-trimester surgical abortion cervical preparation. DESIGN: We conducted a retrospective cohort study, reviewing 145 consecutive charts to compare procedure duration for women who received 400 mcg of buccal misoprostol at least 1 h preprocedure vs. overnight osmotic dilators before dilation and evacuation between 14 weeks, 0 days and 15 weeks, 6 days' gestation. Primary outcome was procedure duration and secondary outcomes included maximum mechanical dilator size, estimated blood loss and side effects. RESULTS: Sixty-four women (44.1%) received buccal misoprostol (mean 1.6 h), and 81 women (55.9%) received overnight osmotic dilators. Groups did not differ regarding mean gestational age or gynecologic history. All procedures in both groups were completed. Procedure duration was not significantly different between the misoprostol and osmotic dilator groups (median 11.0 min vs. 10.0 min, p=.22), even after multivariable linear regression (p=.17). The mean total cervical preparation duration was 1.6 h for women in the misoprostol group compared to 20.3 h in the osmotic dilator group (p<.001). Secondary outcomes did not differ between groups. CONCLUSIONS: We found that at least 1 h of preprocedure misoprostol decreased the duration of cervical preparation for early second-trimester procedures performed by an experienced surgeon. IMPLICATIONS: In this small, retrospective review, at least 1 h of preprocedure buccal misoprostol decreased the duration from cervical preparation initiation to procedure completion in early second-trimester procedures performed by an experienced surgeon. These results should be considered as a pilot evaluation, and further prospective study is needed to further clarify whether this short interval could be applied in general practice.

A double-blind randomized controlled trial of mifepristone or placebo before buccal misoprostol for abortion at 14-21 weeks of pregnancy.

OBJECTIVE: To assess differences in outcomes of misoprostol with or without mifepristone for second-trimester abortion. METHODS: A randomized, double-blind, placebo-controlled trial of buccal misoprostol following placebo or 200mg mifepristone was done in Tunisia among women presenting for abortions at 14-21 weeks of pregnancy between August 2009 and December 2011. Women with a live fetus, a closed cervical os, no cervical bleeding, and no contraindications to study drugs were eligible and underwent randomization (block size 10). Participants returned 24 hours later to receive 400 µg buccal misoprostol every 3 hours until complete fetal and placental expulsion (maximum 10 doses, five per 24-hour period). The primary outcomes were rates of complete uterine evacuation at 48 hours and time to expulsion. RESULTS: A total of 120 women were evenly randomized to treatment. Complete uterine evacuation at 48 hours was recorded in 55 (91.7%) women in the combined group versus 43 (71.7%) in the misoprostol alone group (relative risk 1.28; 95% confidence interval 1.07-1.53). Mean time to complete abortion was 10.4±6.6 hours in the group who received mifepristone versus 20.6±9.7 hours in the misoprostol alone group (P<0.001). Side effects were similar in both groups. CONCLUSION: Adding mifepristone before misoprostol can improve the quality of second-trimester abortion care by making the process faster.

In utero bisphenol A concentration, metabolism, and global DNA methylation across matched placenta, kidney, and liver in the human fetus.

While urine has been an easily accessible and feasible matrix for human biomonitoring, analytical measurements in internal tissues and organs can provide more accurate exposure assessments to understand disease etiology. This is especially important for the endocrine active compound, bisphenol A (BPA), where studies investigating internal doses at sensitive periods of human development are currently lacking. Herein, BPA concentrations, BPA-specific metabolizing enzyme gene expression, and global DNA methylation were characterized across three matched tissues from elective pregnancy terminations of 2nd trimester human fetuses: the placenta, liver, and kidney (N=12 each; N=36 total). Compared to liver (free: 0.54-50.5 ng g(-1)), BPA concentrations were lower in matched placenta (<0.05-25.4 ng g(-1)) and kidney (0.08-11.1 ng g(-1)) specimens. BPA-specific metabolism gene expression of GUSB, UGT2B15, STS, and SULT1A1 differed across each tissue type; however, conjugation and deconjugation expression patterns were similar across the fetus. Average LINE1 and CCGG global methylation were 58.3% and 59.2% in placenta, 79.5% and 66.4% in fetal liver, and 77.9% and 77.0% in fetal kidney, with significant tissue-specific DNA methylation differences in both LINE1 (p-value<0.001) and CCGG content (p-value<0.001). Total BPA concentrations were positively associated with global methylation for the placenta only using the LINE1 assay (p-value: 0.002), suggesting organ-specific biological effects after fetal exposure. Utilizing sensitive human clinical specimens, results are informative for BPA toxicokinetics and toxicodynamics assessment in the developing human fetus.

Effects of a prolonged, 72 hours, interval between mifepristone and gemeprost in second trimester termination of pregnancy: a retrospective analysis.

OBJECTIVE: To evaluate if the 72 hours interval between mifepristone and gemeprost has a similar efficacy compared to the 48 hours interval for second trimester termination of pregnancy STUDY DESIGN: Two-hundred and fifteen consecutive pregnant women, admitted to our hospital, for second trimester TOP, were included in this retrospective analysis. Standard protocol was followed for all patients. On the first day of the procedure oral mifepristone 200 mg was administered. After 72 (group A, n = 78) or 48 hours (group B, n = 113) women were admitted for administration of gemeprost 1 mg pessary as per protocol. The induction to abortion time was defined as the interval between the insertion of the first gemeprost pessary and the expulsion of the fetus. RESULTS: There are no significant differences in the number of pessaries in the two groups. The induction to abortion interval was longer in group A than in group B. Twenty-one women required surgical evacuation of the uterus for retained placenta or incomplete abortion without difference between groups. CONCLUSION: A 48-hours interval between mifepristone and gemeprost leads to better results than a 72-hours interval, with a shorter abortion length and represents the elective method for second trimester TOP.

Myo-inositol, D-chiro-inositol, folic acid and manganese in second trimester of pregnancy: a preliminary investigation.

DESIGN AND PURPOSE: The supplemental administration of myo-inositol, D-chiro-inositol, folic acid and manganese (MDFM) was tested in a prospective, randomized, double-blind, placebo controlled clinical trial, pilot study, to test the hypothesis that its supplemental administration in the second trimester of pregnancy would improve glucose and glycemic parameters and blood pressure. SUBJECTS AND METHODS: Non-obese uniparous healthy pregnant women between 13th and 24th week of pregnancy were divided into two groups: group I, control group with placebo, and the group II, women in treatment with myo-inositol, D-chiro-inositol, folic acid and manganese. The main outcome measures were the comparative analysis of the parameters analyzed at time 0, after 30 days and 60 days; secondary outcome measure was the overall analysis of investigated parameters. RESULTS: 24 women were allocated to receive MDFM and 24 the placebo. The two groups did not significantly differ for demographic, lipidic and glycemic parameter and blood pressure. After 30 days, significantly lower cholesterol (p = 0.0001), significantly lower LDL (p = 0.0013), lower TG (p < 0.0001) and lower glycemia (p = 0.0021) were observed all favoring group II. No significant difference was observed for HDL, diastolic and systolic blood pressure. After 60 days, significant difference was observed for cholesterol (p = 0.0001), LDL (p = 0.0001), HDL (p = 0.0001), TG (p = 0.0001), glycemia (p = 0.0064), all favoring the group treated with MDFM. No significant differences were observed for systolic (p = 0.12) and diastolic blood pressure (p = 0.42). When examining for overall differences between the two groups, a significant difference was observed for examined parameters at time 0 and at time 60; cholesterol (p = 0.0001), LDL (p = 0.0001), HDL (p = 0.047), TG (p = 0.0001) and glycemia (p = 0.019) were reduced in the MDFM group. A significant reduction was also observed in group II for systolic blood pressure after 60 days of intervention (p = 0.0092), but not for diastolic blood pressure (p = 0.29). CONCLUSIONS: MDFM administration after 30 days in pregnancy improved glycemic and lipidic parameters, with significant gain after 60 days, without affecting diastolic blood pressure levels.

Midpregnancy Doppler ultrasound of the uterine artery in metformin- versus placebo-treated PCOS women: a randomized trial.

CONTEXT: Metformin is used to reduce pregnancy complications in women with polycystic ovary syndrome (PCOS), although it is not approved for this indication and solid evidence is lacking. Midpregnancy Doppler ultrasound is one of the best methods for prediction of adverse pregnancy outcome. OBJECTIVE: The objectives of the study were to investigate the following: 1) whether metformin treatment influenced the midpregnancy pulsatility index (PI) of the uterine artery; 2) whether metabolic or endocrine factors affect the PI of the uterine artery of PCOS women; and 3) whether PI predicted adverse pregnancy outcome in PCOS woman. DESIGN: This is a substudy of a randomized, placebo-controlled, double-blind, multicenter study conducted at 11 secondary care centers. We randomly assigned 273 pregnancies to receive metformin or placebo, from the first trimester of pregnancy to delivery. In the present substudy, 231 pregnancies are included, ie, those who completed the ultrasound examinations. MAIN OUTCOME MEASURES: Midpregnancy PI in the uterine artery related to metformin use, androgen levels, an oral glucose tolerance test, and insulin levels was measured. We found no difference in the PI between the metformin and placebo groups. In multivariate analyses, fasting serum glucose of the first and second trimester correlated positively to the midpregnancy PI. Only in univariate analyses a weak correlation between androstenedione and PI was seen. CONCLUSIONS: Metformin treatment did not affect uterine artery blood flow, measured by PI. High fasting blood glucose correlated inversely to uterine artery blood flow. The midpregnancy PI correlated positively to preeclampsia, hypertension, and gestational diabetes mellitus in PCOS pregnancies. Androgen levels correlated only to PI in univariate analyses.
