ABSTRACT
OBJECTIVE: We assessed the association between a short antenatal corticosteroid administration-to-birth interval and neonatal outcome. STUDY DESIGN: A retrospective study was conducted between 2010 and 2020. Eligible cases were singleton preterm live-born neonates born between 24-0/7 and 33-6/7 weeks of gestation and were initiated an ACS course of betamethasone. We divided the first 48 h following the first ACS administration to four time intervals and compared each time interval to those born more than 48 h following ACS administration. The primary outcome was a composite of adverse neonatal outcome, including neonatal mortality or any major neonatal morbidity. RESULTS: A total of 200 women gave birth less than 48 h from receiving the first betamethasone injection, and 172 women gave birth within 2-7 days (48-168 h) from ACS administration. Composite adverse neonatal outcome was higher for neonates born less than 12 h from initial ACS administration compared to neonates born 2-7 days from the first betamethasone injection (55.45% vs. 29.07%, OR 3.45 95% CI [2.02-5.89], p value < 0.0001). However, there was no difference in composite adverse neonatal outcomes between neonates born 12-48 h following ACS administration and those born after 2-7 days. That was also true after adjusting for confounders. CONCLUSIONS: 12-24 h following ACS administration may be sufficient in reducing the same risk of neonatal morbidities as > 48 h following ACS administration. It may raise the question regarding the utility of the second dose of ACS.

OBJECTIVE: To determine, using four-dimensional (4D) transperineal ultrasound, whether the appearance, position or dimensions of sacrocolpopexy mesh implants or the degree of tissue support change in the long term. METHODS: Women who had undergone minimally invasive abdominal sacrocolpopexy for pelvic organ prolapse were invited for follow-up assessment at two consecutive visits at least 1 year apart. All participants completed a Pelvic Floor Distress Inventory questionnaire (PFDI-20) and underwent a pelvic examination by one examiner and had 4D ultrasound volumes obtained by a different examiner. Volumes were analyzed offline for mesh position with the woman at rest and on maximal Valsalva maneuver, and for mesh dimensions and characteristics on three-dimensional orthogonal planes and rendered views, with the operator blinded to the clinical data. Findings were compared between the two examinations. RESULTS: Thirty women attended follow-up assessment at two time points, a median of 22 (range, 12-37) months apart. The median age at the latter visit was 60 (range, 46-72) years, median body mass index was 25.9 (range, 20.8-31.9) kg/m2 , median parity was 3 (range, 1-7) and median time from surgery to first and second visit, respectively, was 11.2 (range, 6-26) months and 33.5 (range, 14-56) months. There were no significant differences between the two time points in symptom scores, reported satisfaction from surgery, pelvic examination findings or pelvic organ descent in any compartment according to ultrasound. While mesh dimensions of anterior and posterior arms did not change significantly over time, both arms descended less on Valsalva at the second follow-up compared with at the first (13.2 ± 6.7 mm vs 21.9 ± 10.0 mm and 9.1 ± 5.3 mm vs 16.1 ± 8.1 mm, respectively, both P < 0.001). There were no mesh erosions, but folding remained a consistent finding, occurring in 80% of women in each assessment. CONCLUSIONS: Characteristics of tissue support and dimensions of sacrocolpopexy mesh implants remained constant over long-term follow-up, with no mesh shrinkage or erosion. Copyright © 2016 ISUOG.

OBJECTIVE: To characterize, using three-dimensional (3D) transperineal ultrasound, the appearance, position and dimensions of mesh implants following minimally invasive abdominal sacrocolpopexy. METHODS: In women who underwent sacrocolpopexy, mesh was evaluated at rest and on maximal Valsalva, on all 3D orthogonal planes and rendered views. Mesh dimensions were obtained by 3D processing in the midsagittal and coronal planes (anterior, posterior and sacral arm) and were analyzed offline, the operator blinded to clinical data. RESULTS: Overall, 62 women, mean age 58.4 (range, 42-79) years were evaluated at a median of 9 (range, 1-26) months following surgery. The anterior arm of the mesh was caudal to the lowermost point of descent of the anterior compartment in 56 (90.3%) women, was equally positioned in five (8.1%) and was cranial in one. The posterior arm was caudal in 44 (71%) women, was equally positioned in 16 (25.8%) and was cranial in two (3.2%). The Y connection and the sacral arm of the mesh could not be adequately seen because of physical limitations of ultrasound (lower resolution at greater depth), large recurrent rectoceles, echogenic stools or folding of mesh remnants. Folding of the mesh was seen in 46 (74.2%) women, folding of the anterior arm in five (8.1%) and folding of the posterior arm in 23 (37.1%). Folding occurred caudally in 26 (41.9%) women, proximally in 11 (17.7%) and in both areas in nine (14.5%). There were no erosions. CONCLUSION: Mesh visualization following minimally invasive abdominal sacrocolpopexy procedures using transperineal 3D/four-dimensional (4D) ultrasound is feasible. Studies are needed to evaluate the correlation between ultrasound measures and prolapse recurrence or mesh erosion.

OBJECTIVE: To assess the role of transperineal ultrasound in the postoperative evaluation of patients undergoing colpocleisis. METHODS: Patients who underwent colpocleisis between July 2009 and January 2011 completed the pelvic floor distress inventory questionnaire (PFDI-20) and underwent pelvic organ prolapse quantification (POP-Q) examination and four-dimensional (4D) transperineal ultrasound. Volumes were analyzed offline for assessment of pelvic organ descent, levator hiatal dimensions, levator avulsion trauma and the location of the colpocleisis scar. RESULTS: The study included 16 women, of mean ± SD age 75.7 ± 2.9 years, median body mass index 28 (range, 21-32) kg/m2 and median parity 2 (range, 0-5); one woman was nulliparous. Nine (56.2%) women were posthysterectomy. The median interval from surgery to ultrasound examination was 6.5 (range, 2-19) months. Most patients did not have symptoms of prolapse. The median pelvic organ prolapse distress inventory (POPDI-6) score was 37.5 (range, 0-75) and the median postoperative clinical POP-Q stage was 1 (range, 0-2). Ultrasound demonstrated clear visualization in all patients. Ten had avulsion defects (six were bilateral). Ultrasound estimated greater prolapse descent for all compartments when compared with the clinical examination. However, this difference was significant for anterior and posterior descent, but not for apical descent. In two women urethral diverticulum was detected on ultrasound; it was neither symptomatic nor clinically apparent. CONCLUSIONS: 4D transperineal ultrasound seems to be a potentially effective tool for the evaluation of vaginal anatomic and functional changes following colpocleisis surgery. Future investigation of the association between ultrasound findings and patients' subjective symptoms in a larger cohort is warranted.

Maternal infection is associated with oxidative stress (OS) and inflammatory responses. We have previously shown that maternal exposure to lipopolysaccharide (LPS) at E18 alters the subsequent offspring immune response. As immune responses are mediated, in part, by OS, we sought to determine if maternal inflammation during pregnancy programs offspring OS and C-reactive protein (CRP) levels. Pregnant Sprague-Dawley rats received intraperitoneal (i.p.) injections of saline or LPS at 18 days' gestation (n = 4), and pups delivered spontaneously at term. At postnatal day 24, male and female offspring received i.p. injection of LPS. Serum lipid peroxides formation (PD) and CRP levels were determined before and at 4 h following the LPS injection. Pups of LPS-exposed dams had significantly higher basal OS (PD 29.4 ± 5.4 v. 10.1 ± 4.8 nmol/ml) compared with controls. In response to LPS, CRP levels (20.4 ± 2.8 v. 5.7 ± 1.0 ng/ml) were significantly higher among pups of LPS-exposed dams than controls. Prenatal maternal exposure to LPS increases baseline OS levels in neonates and CRP levels in response to LPS. These results suggest that maternal inflammation during the antenatal period may induce long-term sequelae in the offspring that may predispose to adult disease.

OBJECTIVES: This study was carried out to determine the prognosis, and the clinical approach, in fetuses with umbilical cord cysts, during the second and third trimesters of gestation, according to our experience and data in the current literature. METHODS: We identified 10 fetuses with umbilical cord cysts that were diagnosed during the second and third trimesters of pregnancy at three referral centers. All underwent detailed ultrasound evaluation at the time of diagnosis and during follow-up. Prenatal karyotype testing was offered to all women. A MEDLINE review of the literature published from 1980 to 2009 was carried out to identify previous studies and case reports of fetuses with umbilical cord cysts. RESULTS: In our series of 10 cases, significant additional abnormalities were observed in two during a detailed sonogram. In one case, trisomy 18 was diagnosed, leading to pregnancy termination, and in the other case a neonate with heart defects and a normal karyotype was born. These results differ from those reported in the literature, in which the association between second- and third-trimester umbilical cord cysts and fetal anomalies ranged from 38 to 100%. CONCLUSIONS: In our study, as in other publications, an association was found between the presence of second- and third-trimester umbilical cord cysts and fetal anomalies. The strong association between second- and third-trimester umbilical cord cysts and aneuploidy in the literature seems to be biased, mainly because of the tendency to report abnormal cases. When these findings are accompanied by additional sonographic abnormalities, the association with aneuploidy is clear and should be an indication for fetal karyotype testing.

OBJECTIVE: To determine sonographic dimensions of the fetal facial profile in normal pregnancy. METHODS: This was a prospective, cross-sectional study of 397 normal healthy fetuses at 14-33 weeks of gestation. After exclusion of the small numbers of patients at the upper GAs, 379 patients between 14.0 and 26.9 weeks of gestation were included in the analyses. The sagittal plane of the fetal facial profile was evaluated using transvaginal and transabdominal ultrasound. Distances from the tip of the nose to the mouth (the line between the lips), from the mouth to the gnathion (lower chin), from the upper philtrum to the mouth, and from the mouth to the upper concavity of the chin were measured and are presented according to gestational age (GA). RESULTS: There was a significant linear correlation between GA and the distance from the tip of the nose to the mouth (r = 0.943; P < 0.00001; y = -37.98 + 7.54 x GA), from the mouth to the gnathion (r = 0.946; P < 0.00001; y = -46.34 + 7.95 x GA), from the upper level of the philtrum to the mouth (r = 0.71; P < 0.00001; y = 0.22 + 3.33 x GA) and from the mouth to the upper concavity of the chin (r = 0.665; P < 0.00001; y = 1.65 + 2.95 x GA). The ratio between the distance from the tip of the nose to the mouth and that from the mouth to the gnathion was also almost constant throughout gestation, as was the ratio between the distance from the upper philtrum to the mouth and that from the mouth to the upper concavity of the chin. CONCLUSIONS: We provide normative data of the fetal facial profile across GA. Our data offer a potential tool for the prenatal diagnosis of abnormal fetal facial profile.

BACKGROUND: Endocardial fibroelastosis is a congenital heart disease known to cause congestive heart failure in early infancy. We report a case using new modalities for early prenatal diagnosis of endocardial fibroelastosis causing fetal heart failure. CASE: A multipara with two children, who died of endocardial fibroelastosis, was referred for fetal echocardiography at 20 weeks' gestation. A mildly asymmetric four-chamber view with slightly enlarged atria and no other fetal heart abnormalities suggested endocardial fibroelastosis. Doppler studies demonstrated abnormal cardiac function with extremely low atrioventricular E/A ratio, defined as the ratio between the rapid ventricular filling (E wave) and the atrial systole (A wave), and abnormal venous flow velocity waveforms establishing the diagnosis. On a repeat scan 2 weeks later, the abnormal morphologic signs suggesting endocardial fibroelastosis were more prominent, and pregnancy was terminated. CONCLUSION: When morphologic signs are not definitive, Doppler studies of the fetal heart may be useful in making the diagnosis of endocardial fibroelastosis.

BACKGROUND: Most congenital pulmonary arteriovenous malformations are associated with hereditary hemorrhagic telangiectasia. During pregnancy, pulmonary hemorrhage can occur, compromising maternal and fetal health. CASES: We studied three pregnancies in two women with hemorrhagic telangiectasia complicated by pulmonary arteriovenous malformations. A 28-year-old primigravida's fetus died at 25 weeks' gestation, and she had embolotherapy with coil springs, which corrected the hypoxemic state. In a subsequent pregnancy she delivered a healthy 2315-g infant at 38 weeks' gestation. A 19-year-old primigravida had spontaneous hemothorax at 26 weeks' gestation with severe hypoxemia and a growth-restricted fetus without umbilical artery diastolic flow. Pulmonary arteriovenous malformation was diagnosed by computed tomography of the maternal lung. She had continued pulmonary bleeding, so emergency lung lobectomy was done. Maternal hypoxemia and umbilical diastolic flow improved, and she had term delivery of a healthy 2250-g infant. CONCLUSION: Antenatal diagnosis and treatment of women with hereditary hemorrhagic telangectasia and pulmonary arteriovenous malformations might prevent potentially life-threatening fetomaternal complications.

OBJECTIVE: Hormone replacement therapy (HRT) is prescribed to most patients with Turner syndrome (TS) although its use in adult TS patients has not been scientifically evaluated. The present study was performed to compare the short-term effects in adult women with Turner syndrome of low-dose oral conjugated oestrogen (0.625 mg, CE) with relatively high dose ethinyl oestradiol (30 microg, EE2); both combined with an oral progestin. DESIGN AND PATIENTS: After 4 months off HRT, 17 young, otherwise healthy women with TS were enrolled in a random, unblinded, crossover study of the two oestrogenic preparations, each given for 6 months. MEASUREMENTS: We compared parameters of oestrogenic activity that would cover immediate changes in hormone levels, biochemistry, bone turnover, uterine and cardiac variables, which constitute risk factors for later development of diabetes, atherosclerosis, osteoporosis and aortic dissection. RESULTS: Serum FSH returned to normal follicular phase levels only on the EE2 regimen. The hypotrophic endometria normalized with either of the two oestrogen regimens with no excessive hypertrophy. Hyperinsulinaemia was suppressed to normal by both EE2 and CE. PTH and 1,25-dihydroxyvitamin D levels increased on HRT (EE2 > CE), and phosphorus decreased. Alkaline phosphatase, osteocalcin and urinary deoxypyridinoline cross-links (DPD) were high off therapy; the former two suppressed to high-normal levels on the EE2 regimen, but not on CE, and DPD did not normalize with either HRT. Lipid profiles in these young TS patients were normal. Liver enzymes were mildly elevated off therapy and suppressed to normal levels on both regimens, but more so with EE2. CONCLUSIONS: The risk factors embodied in hyperinsulinaemia and enhanced bone turnover which, ultimately, have consequences for TS morbidity, are minimized by HRT. In the short term, neither regimen is effective for bone turnover in adult women with Turner syndrome.

OBJECTIVE: To examine the effect of maternal oral glucose ingestion on antepartum FHR indices in normal pregnancies at term. STUDY DESIGN: A prospective study was performed on 44 non-laboring healthy women with normal singleton pregnancy at 37-40 weeks gestation. All women had a normal oral glucose tolerance test at 24-28 weeks gestation. FHR was recorded with the Sonicaid Fetal Monitor System (Oxford 8000), for 30 min prior to and 60 min following oral ingestion of 50 g of glucose in the study group of 27 women, and following water ingestion in a control group of 17 women. RESULTS: All pregnancies had a normal outcome. The maternal blood glucose levels before and 30 and 60 min after glucose ingestion were 70+/-14, 107+/-121, and 106+/-22 mg/dl, respectively (P<0.001). A significant negative correlation was found between the changes in maternal blood glucose levels 30 min after glucose ingestion and the changes in the number of large FHR accelerations at 30 and 60 min after glucose ingestion (r=-0.44, P<0.01 and r=-0.42, P<0.01, respectively). A significant correlation was found between the changes in maternal blood glucose levels 30 min after glucose ingestion and changes in episodes of low FHR variation at this time period (r=0.45, P<0.01). No significant changes in any of the FHR variables were noted in the control group. CONCLUSION: In normal pregnancies FHR indices of variation tend to decrease after maternal oral ingestion of glucose.

OBJECTIVE: Cesarean section is one of the most common operations. The new technologies of postoperative pain treatment such as patient-controlled analgesia, are expensive and may limit women caring for their newborns shortly after delivery. The present study assessed patient satisfaction with oral analgesia following cesarean section. STUDY DESIGN: An open prospective study was conducted on all women who had a cesarean section with epidural analgesia, during two consecutive periods of 3 months each. In the first group of 109 women, an oral solution of 1 g dipyrone was allowed every 4 h, upon patient request. Patients requesting additional analgesia were administered a tablet of 30 mg immediate-release morphine sulfate. In the second group of 90 women, the same protocol was used; however, oral morphine was the drug of choice and dipyrone was used for rescue analgesia. Pain intensity and satisfaction were self-evaluated by patients using a visual analog scale. RESULTS: The results of each study period were independently evaluated. The demographic and obstetrical variables were similar in both groups. The duration of analgesic effect of dipyrone was 6.5 h and the satisfaction score was 90. The duration of analgesic effect of oral morphine was 5.05 h and the satisfaction score was 83.7. Overall, patients in both groups requested only 25% of the permissible dosage of analgesia. CONCLUSIONS: Oral analgesia following cesarean section provides satisfactory pain relief, is easily administered, and is a substantially less costly alternative to the new pain treatment technologies currently in use.

OBJECTIVE: To assess internal jugular vein blood flow patterns during the second half of pregnancy in normal and growth-restricted fetuses. METHODS: We did Doppler ultrasound studies of internal jugular veins and the inferior vena cavas longitudinally on 21 normal singleton fetuses from 20 weeks to term, and on eight growth-restricted fetuses with absent end-diastolic flow at the umbilical artery (UA). The three components of the venous flow velocity waveforms were used to calculate peak velocity ratio: Peak systolic velocity (S wave) minus reverse peak velocity (R wave) divided by peak velocity during early diastole (D wave) and velocity time integral ratio: systolic velocity time integral minus reverse velocity time integral divided by velocity time integral during early diastole. Statistical analysis of longitudinal measurements used K-related samples Friedman test; groups were compared with Mann-Whitney U test and chi(2) test. RESULTS: In normal fetuses we found significant increases in peak velocity ratio and velocity time integral ratio of internal jugular veins and the inferior vena cavas throughout gestation. The mean +/- standard deviation (SD) of the internal jugular veins peak velocity ratio (1.12 +/- 0.4 versus 1.46 +/- 0.15, P <.05) and velocity time integral ratio (1.1 +/- 0.2 versus 1.55 +/- 0.17, P <.05) were significantly lower in growth-restricted fetuses compared with normal fetuses at 28-32 weeks' gestation but inferior vena cava indices were not. None of the eight growth-restricted fetuses had umbilical venous pulsations or changes in inferior vena cava or ductus venosus blood flow patterns. All had arterial pH above 7.15 at birth. CONCLUSION: Growth-restricted fetuses with absent end-diastolic velocity in the UA have changes in internal jugular vein blood flow patterns that probably indicate increased cerebral blood flow, more evidence of redistribution of blood flow in growth-restricted fetuses that can be used to maintain them.

Inherited and acquired thrombophilia are associated with recurrent pregnancy loss (RPL). We have evaluated the efficacy and safety of the low molecular weight heparin enoxaparin in 50 women, (mean age 26 +/- 3 years) with RPL (> or =3 losses in 1st, > or =2 losses in 2nd and > or =1 loss in 3rd trimester) who were found to harbor thrombophilia. Twenty-seven had a solitary thrombophilic defect, and twenty-three women had combined thrombophilic defects: 17--two defects and 6--three defects. Following diagnosis of thrombophilia, sixty-one subsequent pregnancies were treated with the low molecular weight heparin enoxaparin throughout gestation until 4 weeks after delivery. Dosage was 40 mg/day in women with solitary defect and 80 mg/day in combined defects. Aspirin, 75 mg daily was given in addition to enoxaparin to women with antiphospholipid syndrome. Forty-six out of 61 (75%) gestations treated by enoxaparin resulted in live birth compared to only 38/193 (20%) of the untreated pregnancies in these 50 women prior to diagnosis of thrombophilia (p <0.00001). In 23 women without a single living child following 82 untreated gestations, antithrombotic therapy resulted in 26/31 (84%) successful deliveries (p <0.0001). In 20 women with a prior living child, antithrombotic therapy improved successful delivery from 33/86 (38%) to 20/21 (95%) (p <0.0001). Enoxaparin dose of 40 mg/day resulted in live birth in 24/35 (69%) of gestations, compared to 19/23 (83%) gestations in women treated with 80 mg/day (p = 0.37). Only one thrombotic episode and one mild-bleeding episode were noticed during enoxaparin therapy. Enoxaparin is safe and effective in prevention of pregnancy loss in women with inherited and acquired thrombophilia.

OBJECTIVE: The objective was to evaluate the accuracy of blood flow measurements by power Doppler in endometrial vessels in women with postmenopausal bleeding (PMB). METHODS: Sixty consecutive patients with PMB participated in the study. Endometrial thickness and power Doppler measurements of small vessels in the endometrium and subendometrial tissue were performed prior to dilatation and curettage. Correlation between Doppler indices, endometrial thickness (by transvaginal sonography), and histopathologic examination was performed. A Student t test was used for statistical analysis with P < 0.05 as the level of significance. RESULTS: Fourteen positive cases were found: 11 endometrial cancers, 1 sarcoma, 1 simple hyperplasia, and 1 complex hyperplasia with atypia. Measurements of endometrial thickness using a cutoff point of 5 mm revealed a sensitivity of 78% and specificity of 45.6% (P > 0.05, NS) for detecting endometrial pathology. Power Doppler measurements (pulsatility index cutoff point = 1.0) revealed a sensitivity of 85. 7% and specificity of 89% (P = 0.001) for detecting endometrial pathology. CONCLUSIONS: The noninvasive methods for endometrial evaluation are not sensitive enough to exclude endometrial pathology. When invasive methods could not be performed, the combination of transvaginal sonography and power Doppler imaging provided the best results. When both modalities are negative, the probability of cancer is less than 5%.

OBJECTIVE: To examine the influence of epidural analgesia on labor and delivery in nulliparous and multiparous women. DESIGN: Data were collected on 847 consecutive parturients with singleton pregnancy and vertex presentation (384 nulliparous and 463 multiparous). The obstetrical and labor characteristics including maternal age, parity, gestational age, previous cesarean section, instrumental delivery, mode and timing of analgesia, mode of delivery, indications for cesarean section or instrumental delivery were analyzed comparing patients who received epidural analgesia with women who received systemic analgesia. RESULTS: Epidural analgesia was administered in 233 nulliparous and 141 multiparous women. A stepwise logistic regression analysis revealed that epidural analgesia independently affected the rate of non-spontaneous delivery and the duration of the second stage of labor in nulliparous (P=0.0017 and P=0.0036, respectively) and multiparous (P=0.001 and P=0.0081, respectively) women. Epidural analgesia independently affected the duration of labor only in nulliparous women (P=0.0001). CONCLUSION: Women should be informed that prolongation of labor and increase in nonspontaneous deliveries should be expected when choosing epidural analgesia in labor.

An association between fetal loss and thrombophilia has recently been described but has not been yet fully elucidated. We have evaluated prospectively the prevalence of the three common thrombophilic polymorphisms (TP) factor V G1691A (Leiden), thermolabile-methylenetetrahydrofolate reductase (TL-MTHFR) C677T and factor II G20210A mutations, in 76 women with fetal loss (> or =3 in first, > or =2 in second, > or =1 in third trimester) without apparent cause and 106 controls without fetal loss. Thirty seven out of 76 (49%) of the women in the fetal loss group had at least one TP compared to only 23/106 (22%) in the control group (p = 0.0001 ). Factor V-Leiden was more common in the fetal loss group 24/76 (32%) compared to the control group 11/106 (10%) (OR = 4.0, 95% CI: 1.8-8.8, p <0.001). Five of the 76 patients (7%) were homozygous for factor V-Leiden compared to none of the controls (p = 0.012). A trend, albeit no statistically significant difference was found between women with fetal loss and control groups regarding factor II G20210A (8% vs. 4% respectively, OR = 2.2, 95% CI: 0.6-8.0, p = 0.23) and MTHFR C677T (18% vs. 10% respectively, OR = 1.95, 95% CI: 0.83-4.6, p = 0.12). Combined TP were documented in 6/76 (8%) patients compared to 1/106 (1%) in controls (OR = 9.0, 95% CI: 1.1-76, p = 0.02). Second or third trimester fetal loss were more common cause of pregnancy termination in 37 patients with TP compared to 39 patients without TP (57/158 (36%) vs. 23/135 (17%) respectively, (p = 0.0004). Thrombophilic polymorphisms are common in women with fetal loss without apparent cause and are associated with late pregnancy wastage. Combinations of TP increase the risk for fetal loss.

OBJECTIVE: To examine possible changes in cardiac function in fetuses of pregestational diabetic mothers. METHODS: We conducted a prospective longitudinal study of 31 women whose pregnancies were between 22 weeks' gestation and term, and who had pregestational diabetes. All diabetic women included in the study had glycosylated hemoglobin lower than 6.5%. All patients included in the study had an early ultrasound confirming gestational age. Doppler studies of the blood flow through the mitral and tricuspid valves were done every 4 weeks using a pulsed-wave Doppler ultrasound device with a 3.5- or 5-MHz transducer. The following indices were calculated from the flow velocity waveforms: the peak velocity during the rapid ventricular filling (E wave) and during the atrial systole (A wave), and the ratio between these velocities (E/A ratio); and the velocity time integral of the atrioventricular blood flow (this integral correlates with volume flow). A comparison between the Doppler indices obtained in fetuses of diabetic women and of normal women was made by using the Mann-Whitney test. RESULTS: Each patient had four to five fetal echocardiographic examinations at 22, 26, 30, 34, and 38 weeks' gestation. The E/A ratio of the mitral and tricuspid valves did not increase in fetuses of diabetic women during the third trimester and was significantly higher in fetuses of nondiabetic women compared with fetuses of diabetic women at 34 and 38 weeks' gestation. The velocity time integral of the mitral and tricuspid valves multiplied by heart rate was higher, but not significantly, in fetuses of nondiabetic women compared with fetuses of diabetic women at 34 and 38 weeks' gestation. The E-wave of the mitral and tricuspid valves increased in both groups throughout gestation. The A-wave of the mitral and tricuspid valves increased only in fetuses of diabetic women throughout the third trimester and was significantly higher at 34 and 38 weeks' gestation compared with fetuses of nondiabetic women. CONCLUSION: Differences in atrioventricular blood flow patterns between fetuses of diabetic women and normal fetuses do not necessarily result from differences in cardiac compliance.

OBJECTIVE: Our goal was to assess the effect of uterine activity on fetal heart rate indexes during the active phase of labor with a computerized fetal heart rate monitoring system. STUDY DESIGN: Twenty-six healthy women were studied in active labor without analgesia. Fetal heart rate was analyzed by a computerized system (Sonicaid, System 8000), providing a numeric analysis of the fetal heart rate indexes. Montevideo and Alexandria units were used for quantitative assessment of contractions. RESULTS: A significant correlation was found between Montevideo units and short-term variation (r = -0.62, p < 0.001), episodes of high (r = -0.48, p < 0.01) and low (r = 0.58, p < 0.01) fetal heart rate variation, and frequency of large accelerations (r = -0.49, p < 0.01). A significant correlation was also found between Alexandria units and short-term variation (r = -0.645, p < 0.001), episodes of high fetal heart rate variation (r = -0.58, p < 0.01), and frequency of large accelerations (r = -0.49, p < 0.01). CONCLUSIONS: In active labor fetal heart rate variability is significantly affected by the intensity and duration of contractions.
