RESUMO
BACKGROUND AND AIM: Studies have shown that increased maternal cortisol level is associated with child adverse health outcomes. Hair cortisol (HC) is suitable for assessing long-term circulating cortisol concentration. Only two previous studies reported beneficial associations between cortisol and residential greenness during pregnancy and no study focused on the first trimester. Our aim was to evaluate the association between residential greenness and first trimester HC levels among pregnant women in Israel. METHODS: Women were recruited during second and third trimesters. Hair samples were collected from the scalp and retrospective HC levels during the first trimester were quantified for 217 women. HC levels were natural log transformed and outliers were excluded. Based on geocoded birth address, small area sociodemographic status (SES) and mean residential surrounding greenness were calculated using high-resolution satellite-based Normalised Difference Vegetation Index (NDVI) data at 100, 300 and 500-m buffers in a cross-sectional approach. In addition, longitudinal exposure to mean greenness during a week preconception and during the first trimester were calculated. Missing covariates were imputed and linearity of the associations were evaluated. Generalized linear models were used to estimate the crude and adjusted associations controlled for the relevant covariates. RESULTS: After exclusion of outliers, for 211 women, crude and adjusted beneficial associations between exposure to higher mean NDVI and HC levels were observed for all the exposure measures. An increase in 1 interquartile range of greenness (100 m buffer) was associated with a statistically significant lower estimated natural log mean HC level (-0.27 95% CI: -0.44; -0.11). The associations were robust to adjustment for covariates. The findings were consistent for different buffers, for the longitudinal approach, when all observations were included in the analysis and slightly stronger associations were observed for women with addresses geocoded at the home or street level. For most of the exposure measures, stronger associations were observed among those of lower sociodemographic status. CONCLUSION: Our findings that more greenness associated with reduced maternal cortisol levels measured in the hair during the first trimester, could have substantial implications for urban planners and public health professional. If our observations will be replicated, it may present a useful avenue for public-health intervention to promote health through the provision of greenness exposure during early pregnancy, specifically to disadvantage populations.

BACKGROUND: To evaluate the efficacy of virtual reality (VR) as a distraction technique in the management of acute pain and anxiety during amniocentesis. STUDY DESIGN: A randomized controlled trial was conducted between September 2020 and October 2020 involving 60 women undergoing mid-trimester amniocentesis. Thirty women were assigned randomly to the VR intervention (immersive video content as a distraction method) group and 30 to the standard care group using a predetermined randomization code. The primary outcome measure was the visual analog scale (VAS) pain score, along with the women's ratings of their extent of anxiety experienced during the procedure. The VAS consisted of a 10 cm line ranging from 0 to 10 (anchored by 0 = no pain and 10=very severe pain). Anxiety was assessed on Spielberger's state-trait anxiety inventory (STAI) questionnaire. RESULTS: The patients' characteristics and obstetric data were similar in both groups. The ratings on the VAS indicated that the VR intervention was associated with significantly less pain than the ratings in the standard of care group; namely, 2.5 ± 1.5 vs. 3.8 ± 1.7, respectively (95 % CI 0.44-2.13; p = 0.003). There were no significant differences in maternal anxiety levels before and after amniocentesis. CONCLUSION: The VR intervention as a distractive technique emerged as effective in reducing pain during amniocentesis. It is easy to use, relatively inexpensive, has the advantage of no serious side effects, and may decrease the fear of pain that can affect patients' experiences and compliance with this procedure.

Background: The two most commonly used nomograms for amniotic fluid index (AFI) were developed by Moore and Cayle and Magann et al. However, there are several inconsistencies between the two methods.Objective: The aim of the study was to determine whether these differences carry clinical significance.Methods: A retrospective cohort of women with singleton pregnancies evaluated for AFI during pregnancy at a tertiary medical center in 2007-2014 were divided into five groups: group A, definite oligohydramnios-AFI below the fifth percentile according to the nomograms of both Moore and Cayle and Magann et al.; group B, intermediate oligohydramnios-AFI below the fifth percentile according to only one nomogram (Moore and Cayle); group C, euhydramnios-normal AFI according to both nomograms; group D, intermediate polyhydramnios-AFI above the 95th percentile according to one nomogram (Magann et al.); group E, definite polyhydramnios-above the 95th percentile according to both nomograms. The association of group by maternal and perinatal outcomes was analyzed.Results: A total of 6987 women were included: group A, 996 (14%); group B, 1344 (19%); group C, 2561 (37%); group D, 1051 (15%); group E, 1034 (15%). Group B (intermediate oligohydramnios) was characterized by significantly lower rates of adverse perinatal outcomes than group A (definite oligohydramnios): small for gestational age neonate (12.3 versus 15.2%, p = .05), neonatal intensive care unit admission (11.1 versus 21.5%; p < .001), composite respiratory outcome (4.8 versus 9.8%; p < .001), and neonatal sepsis (6.4 versus 10.8%; p < .001). No such differences were found between groups B and C. Group D (intermediate polyhydramnios) differed from group E (definite polyhydramnios) by lower rates of 5 minutes Apgar score <7 (1.3 versus 3.2%; p = .003), neonatal intensive care unit admission (10.9 versus 14.4%; p = .02), and major congenital anomalies (1.7 versus 5.6%; p = .02). There was no difference in these parameters between groups D and C.Conclusion: This study suggests that intermediate oligohydramnios and intermediate polyhydramnios are not associated with adverse perinatal outcomes. Outcome in these pregnancies is similar to pregnancies with euhydramnios. Commonly used AFI nomograms should be updated.

Maintaining pregnancy to term is important as preterm delivery is a risk factor for impaired infant development, which may have negative long-term consequences. Therefore, developing biomarkers that can predict pregnancy longevity during early gestation is essential for the prevention of preterm birth. Here we explored whether maternal hair testosterone and cortisol, representing the pre-conception and first trimester periods respectively, may be used to predict pregnancy longevity. We recruited 125 pregnant women that contributed hair samples and answered a personal information questionnaire that included pre-conception smoking. We quantified steroids using commercial enzyme-linked immunosorbent assay kits. Gestational age at delivery was obtained from medical records. We used General Linear Models to predict gestation length. The model that included first trimester cortisol, pre-conception smoking, pre-conception testosterone and the interaction between first trimester cortisol and pre-conception smoking predicted 13% of the variance in gestation length (R2 = 0.130; n = 105; p = 0.007). First trimester cortisol was the best predictor of gestational length. Women with high levels of cortisol in their first trimester had an increased probability of a full-term delivery. The effect of cortisol was especially pronounced in smokers (ß = 1.69), compared to non-smokers (ß = 0.45). Pre-conception testosterone also contributed to the model. Our study suggests that hair steroids may be used to predict pregnancy longevity, together with other contributing factors.

OBJECTIVES: To report the preoperative ultrasound (US) signs of isolated fallopian tube torsion in surgically verified cases and to estimate whether preoperative US detection of this condition can be improved. METHODS: The charts of 27 women with a surgical diagnosis of isolated fallopian tube torsion at a tertiary medical center from 2005 to 2016 were retrospectively reviewed. Data were collected from the electronic database of the US unit and compared with the surgical findings. RESULTS: Isolated fallopian tube torsion was correctly diagnosed by US before surgery in 8 of the 27 women (29.6%). In the remainder, the US signs were attributed to torsion of the ovary or the entire adnexa (n = 13), or no torsion was suspected (n = 6). Fallopian tube edema was listed as a US finding in 7 patients, of whom 5 had a correct diagnosis of isolated fallopian tube torsion. The presence of a paraovarian cyst concomitant with normal-appearing ovaries was assumed by US in 5 of the 8 cases that were accurately diagnosed as isolated fallopian tube torsion. The most misinterpreted US finding was an ovarian cyst (suspected in 10 patients and verified at surgery in 2). Absence of blood flow was described in 12 women, of whom 5 had an accurate diagnosis of isolated fallopian tube torsion. Six of the patients with a correct US diagnosis were adults (37.5% of total adults), and 2 were adolescents (18.2% of total adolescents). CONCLUSIONS: The US diagnosis of isolated fallopian tube torsion is challenging. A high index of suspicion is necessary to improve its detection, especially when there are possible US signs of torsion in the presence of a normal-appearing ovary.

OBJECTIVE: To determine the rate of chromosomal cytogenetic abnormalities in fetuses with late onset abnormal sonographic findings. DESIGN: Retrospective cohort of women who underwent amniocentesis at or beyond 23 weeks of gestation, for fetal karyotype and chromosomal microarray analysis, indicated due to late onset abnormal sonographic findings. RESULTS: All 103 fetuses had a normal karyotype. Ninety-five women also had chromosomal microarray analysis (CMA) performed. The detection rate of abnormal CMA (5/95, 5.3%) was similar to that of women who underwent amniocentesis due to abnormal early onset ultrasound findings detected at routine prenatal screening tests during the first or early second trimester (7.3%, P=0.46) and significantly higher than that for women who underwent amniocentesis and CMA upon request, without a medical indication for CMA (0.99%, P<0.0001). CONCLUSIONS: Late onset sonographic findings are an indication for amniocentesis, and if performed, CMA should be applied to evaluate fetuses with late onset abnormal sonographic findings.

OBJECTIVES: The use of sonography-based Automated Volume Count (SonoAVC; GE Healthcare, Kretz, Zipf, Austria) leads to substantially lower intraobserver and interobserver variability with a considerable advantage in time gain for both the physician and patient. It offers the possibility of continuous training and standardization of follicular monitoring. Manual and automated follicular measurements during in vitro fertilization (IVF) are reported to be comparable during gonadotropin-releasing hormone (GnRH) agonist treatment. The aim of our study was to evaluate the effect of follicle tracking with 3-dimensional (3D) SonoAVC on treatment outcomes in GnRH antagonist IVF cycles. METHODS: A prospective trial included 54 women undergoing their first to fourth GnRH antagonist IVF cycles. Follicle tracking from the initiation of ovarian stimulation until the day of oocyte retrieval and timing of oocyte retrieval was done either by conventional 2-dimensional (2D) sonography or 3D SonoAVC (open-labeled parallel assignment). In both groups, recombinant human chorionic gonadotropin was injected when there were at least 3 leading follicles measuring 17 mm. The primary outcome was the oocyte maturation rate, and secondary outcomes were the fertilization rate and clinical pregnancy rate. RESULTS: The number of retrieved oocytes, number and rate of mature oocytes, fertilization rate, and clinical pregnancy rate were similar for 2D sonography and 3D SonoAVC. On a multivariate regression analysis, the use of 3D sonography was not a significant independent predictor of mature oocytes or clinical pregnancy rates. CONCLUSIONS: Follicle tracking with 3D sonographic follicular volume measurements does not achieve better fertility outcomes than standard 2D sonography.

PURPOSE: The purpose of this study is to compare uterine sonographic characteristics in early puerperium, following vaginal versus cesarean deliveries; and in women with abnormal third stage of labor, compared to uncomplicated vaginal delivery. MATERIALS AND METHODS: This is a prospective study of women after delivery of singleton, appropriate-for-gestational-age weight, term neonates; 66 women delivered vaginally and 33 delivered by cesarean section. Sonographic uterine dimensions (height, length, and width), intracavitary thickness and its echogenicity (at level of fundus, midcavity and cervix) were recorded at less than and after 24 h from delivery, and compared between women delivered vaginally and by cesarean section. Among women delivered vaginally, data were further analyzed according to whether women underwent manual revision of the uterine cavity. RESULTS: Sonographic evaluations were taken at 15.4 (4.3-24.0) and 39.5 (28.8-108.8) hours after delivery (median, range). We found no clinically significant differences in uterine characteristics according to mode of delivery or according to manual revision of the uterine cavity. The sonographic appearance of the uterus was similar when performed at less than or after 24 h from delivery. CONCLUSIONS: Postpartum sonographic evaluation of the uterus appears similar after vaginal and cesarean deliveries.

OBJECTIVE: To evaluate the association between first-trimester inter- and intrafetal size discrepancies and pregnancy outcome, among bichorionic-biamniotic twins conceived by IVF. DESIGN: A retrospective study design was used. SETTING: Tertiary university-affiliated medical center. PATIENT(S): All women with a viable first-trimester bichorionic-biamniotic twin gestation, who conceived after IVF in 2007-2015. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The association between fetal size differences and pregnancy outcome was analyzed. Intrafetal size discordance was defined as a difference between the actual gestational age calculated by ovum pickup (OPU) date and the evaluated gestational age by crown-rump length (CRL), for each twin. Intertwin size discrepancy was defined as a difference in CRL between the twins. The primary outcome was the number of live-born fetuses; the secondary outcome measures were gestational age at birth, birth weight percentile, and birth weight discordancy. RESULT(S): A total of 277 women met the study criteria and were divided into three groups by outcome: 218 (78.7%) live-born twins, 41 (14.8%) live-born singleton, and 19 (6.5%) non-live-born pregnancy. Among the smaller than expected twin, the association of CRL-OPU differences with the primary outcome was significant for twin live-born delivery (-1.43 day), singleton live-born delivery (-4.12 days), and non-live-born pregnancy (-6.72 days). For the relatively larger twin, the association was significant for non-live-born pregnancy (-4.33 days) compared with any live-born delivery, either singleton (-0.95 days) or twin (-0.21 days). CONCLUSION(S): Among IVF conceived twin gestations, a CRL-OPU gap was associated with an increased risk of a negative pregnancy outcome.

OBJECTIVES: Women with undiagnosed pelvic lesions are often referred for evaluation and treatment. Transvaginal ultrasound-guided fine needle aspiration (TVUS-FNA) biopsy can assist in making management decisions. We describe our experience with this modality. METHODS: We performed a retrospective chart review of all women who had a TVUS-FNA biopsy between January 2004 and December 2014. Charts were reviewed for clinicopathologic information. The pathologic results of the TVUS-FNA were compared with the final diagnosis. RESULTS: Fifty-nine women underwent TVUS-FNA; the median age was 66 years (range 27-85). Thirty-three lesions were evaluated by fine-needle aspiration biopsy of the solid structure and 26 by aspiration of fluid for cytology. Pathologic feasibility rate was 88% (52/59). Of those with evaluable tissue, the sensitivity of the procedure was 100% and the specificity 92%. Considering the seven inconclusive results, the procedure had sensitivity of 88% (29/33) and specificity of 88% (23/26). Overall accuracy of TVUS-FNA for this patient cohort was 85%. No patient characteristics were found to distinguish between accurate and inaccurate or inconclusive TVUS-FNA result. No complications were noted. CONCLUSIONS: TVUS-FNA offers an excellent modality for the diagnosis and management of deep pelvic lesions otherwise not amenable for histologic evaluation.

OBJECTIVE: To evaluate the association between small crown-rump length (CRL) and fetal loss ≤22 weeks in IVF pregnancies. METHODS: A retrospective analysis of prospectively collected data at a university-affiliated medical center. All singleton IVF pregnancies within a 5-year period, with a live embryo on first-trimester ultrasound and verified pregnancy outcome were included. Rates of fetal loss ≤22 weeks were compared between pregnancies with a CRL ≤tenth percentile and above the tenth percentile of our population. RESULTS: Overall, 397 pregnancies met inclusion criteria. Ninety-five percent of CRL measurements were performed at 40-80 gestational days. All live-embryo's CRL measurements, from 40 to 80 mm, were plotted against expected gestational age (in 5-day clusters), with calculation of the tenth percentile for every gestational age. Total of 64 pregnancies had CRL ≤tenth percentile for gestational age. The rate of fetal loss in this group was significantly higher than in pregnancies with CRL >tenth percentile (17.2 vs. 6.6%, p = 0.005, OR = 2.93, 95% CI 1.2-6.7). In both groups, the majority of fetal losses occurred ≤10 weeks of gestation. CONCLUSION: In IVF pregnancies with a live embryo, a small CRL at 40-80 days' gestation may predict fetal loss. Repeated ultrasound should be considered after 1-2 weeks.

OBJECTIVE: In cases of nonvisualization of the fetal gallbladder (NVFGB), we investigated whether amniotic fluid levels of gamma-Glutamyl transpeptidase (GGTP) can distinguish normal development or benign gallbladder agenesis from severe anomaly such as biliary atresia. METHODS: This is a retrospective cohort study of pregnancies in which the gallbladder was not visualized in the second-trimester fetal anatomy scan. Levels of GGTP in amniotic fluid were analyzed prior to 22 weeks of gestation by amniocentesis. Data were collected regarding other fetal malformations, fetal karyotype, and screening results for cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations. RESULTS: Of 32 cases of NVFGB, 27 (84%) had normal GGTP levels and a normal CFTR gene screening, and 1 of them had an abnormal karyotype. Three of the 5 cases with low GGTP were diagnosed with extrahepatic biliary atresia, proven by histopathological examination following termination of pregnancy. The fourth case had hepatic vasculature abnormality and the fifth isolated gallbladder agenesis. In 22 of 32 cases (68.7%), the gallbladder was detected either later in pregnancy or after delivery. CONCLUSION: The findings support low levels of GGTP in amniotic fluid, combined with NVFGB, as a sign of severe disease, mainly biliary atresia. Normal GGTP levels, concomitant with isolated NVFGB, carry a good prognosis.

BACKGROUND: We previously reported that chemotherapy-induced ovarian toxicity may result from acute vascular insult, demonstrated by decreased ovarian blood flow and diminished post-treatment anti-Müllerian hormone (AMH) levels. In the present study, we report the continuous prospective evaluation of ovarian function in that cohort. METHODS: Patients (aged <43 years) with localized breast cancer were evaluated by transvaginal ultrasound prior to initiation of chemotherapy, immediately at treatment completion, and at 6 and 12 months after treatment cessation. Doppler flow velocity indices of the ovarian vasculature (resistance index [RI], pulsatility index [PI]) were visualized. Hormone markers of ovarian reserve were assessed at the same time points. RESULTS: Twenty patients were enrolled in the study. Median age was 34 ± 5.24 years. Ovarian blood flow was significantly reduced immediately following chemotherapy (both RI and PI; p = .01). These parameters were partially recovered at later points of assessment (6 and 12 months after treatment); patients aged <35 years significantly regained ovarian blood flow compared with patients aged >35 years (p < .05). AMH dropped dramatically in all patients following treatment (p < .001) and recovered in only 10 patients. Hormone markers of ovarian reserve shortly after chemotherapy depicted a postmenopausal profile for most patients, accompanied by related symptoms. Follicle-stimulating hormone (FSH) levels recovered in 14 of 20 patients and significantly returned to the premenopausal range in patients aged <35 years (p = .04); 10 of 20 resumed menses at 12 months. The pattern of vascular impairment was lessened in patients treated with a trastuzumab-based protocol, although results did not reach statistical significance (p = .068). CONCLUSION: Continuous prospective evaluation of ovarian vasculature and function in a cohort of young patients during and after chemotherapy indicated that ovarian toxicity may derive from acute vascular insult. Age may affect whether patients regain ovarian function, whereas recovery of blood flow and premenopausal FSH levels at later assessment was notable in patients aged <35 years. IMPLICATIONS FOR PRACTICE: This study explored the role of vascular toxicity in mediating ovarian impairment and recovery following chemotherapy. Continuous prospective evaluation of ovarian vasculature and function in a cohort of young patients during and after chemotherapy indicated that ovarian toxicity may derive from acute vascular insult. Future studies are warranted to further characterize patterns of vascular toxicity of various chemotherapies in clinical practice and to assess the role of chemotherapy-induced vascular toxicity for specific end organs such as the ovary with systemic vascular effect. Elucidating the cause of impairment may facilitate development of measures to minimize vascular toxicity and consequences of acute vascular insult.

OBJECTIVE: We aimed to evaluate whether pre-recognition of small for gestational age (SGA) at late preterm or term pregnancies, has an impact on pregnancy outcome. METHODS: Retrospective analysis of SGA newborns, stratified to those with suspected or unsuspected IUGR according the sonographic estimated fetal weight (EFW), below the 10th percentile for gestational age (n = 619), with fetuses not suspected as SGA (EFW ≥10th percentile) preformed up to 7 days prior to delivery (n = 1770). RESULTS: SGA was correctly diagnosed prior to delivery in 26% of the fetuses. Women with suspected SGA were delivered earlier (37.9 ± 1.7 versus 38.8 ± 1.4 weeks, p < 0.001) and at a lower birth weight (2280 ± 321 versus 2454 ± 263 grams, p < 0.001). They also had higher rates of induction of labor (19.1% versus 6.2%, p < 0.001) and cesarean delivery (29.1% versus 19.8%, p < 0.001). Fetuses suspected for SGA had higher rate of neonatal adverse outcome, but on multivariate analysis suspected SGA (aOR 0.41, 95% CI 0.20-0.86), birthweight (aOR 0.67, 95% CI 0.5 to -0.77 for each additional 50 g), gestational age at delivery (aOR 0.63, 95% CI 0.56-0.71 for each additional week) and spontaneous vaginal delivery (aOR 0.88, 95% CI 0.19-3.89) were independently associated with an improved neonatal composite outcome. CONCLUSION: Identification of SGA may improve neonatal outcome. However, by itself, it is not an indication for intervention, which may lead to adverse outcome.

OBJECTIVE: To define prenatal sonographic predictors of ureteropelvic junction obstruction requiring postnatal pyeloplasty, in fetuses with isolated hydronephrosis. METHODS: Retrospective data on prenatal sonographic parameters were compared between patients who had been diagnosed prenatally with hydronephrosis and either underwent postnatal pyeloplasty for ureteropelvic junction obstruction (n = 39) or were treated conservatively (n = 30). RESULTS: Significant differences between the surgically and conservatively treated patients were found for mean anterior-posterior renal diameter (22.8 ± 8.6 vs 14.2 ± 5.9 mm, respectively, p < 0.0001) and parenchymal thickness (5.9 ± 2.8 vs 8.1 ± 2.6 mm, p = 0.009). Anterior-posterior diameter >14 mm was the best single predictor of the need for surgery (area under the ROC curve, 0.817), with sensitivity 77%, specificity 69%, positive predictive value (PPV) 77% and negative predictive value (NPV) 69% (ß = 1.17, 95%CI = 1.07-1.28, p < 0.001). Mean ratio of anterior-posterior diameter to parenchymal thickness was significantly higher in the postnatal pyeloplasty group (5.4 ± 4.5 vs 2.1 ± 1.4, p = 0.0001). A ratio >2.1 had a sensitivity of 87% and specificity of 65% for the need for surgery (area under the curve 0.822, PPV 79%, NPV 77%; ß = 1.92, 95%CI = 1.16-3.17, p < 0.001). CONCLUSION: In cases of prenatal isolated hydronephrosis, the pelvic anterior-posterior diameter and parenchymal thickness may predict the need for postnatal pyeloplasty. A ratio of >2.1 of pelvic anterior-posterior diameter to parenchymal thickness suggests ureteropelvic junction obstruction and supports the use of more intensive prenatal and postnatal surveillance.

OBJECTIVE: To determine whether the predictive accuracy of sonographic cervical length (CL) for preterm delivery (PTD) in women with threatened preterm labor (PTL) is related to gestational age (GA) at presentation. STUDY DESIGN: A retrospective cohort study of all women with singleton pregnancies who presented with PTL at less than 34 + 0 weeks and underwent sonographic measurement of CL in a tertiary medical center between 2007 and 2012. The predictive accuracy of CL for PTD was stratified by GA at presentation. RESULTS: Overall, 1077 women who presented with PTL have had sonographic measurement of CL and met the study inclusion criteria. Of those, 223 (20.7%) presented at 24 + 0-26 + 6 weeks (group 1), 274 (25.4%) at 27 + 0-29 + 6 weeks (group 2), 283 (26.3%) at 30 + 0-31 + 6 weeks (group 3), and 297 (27.6%) at 32 + 0-33 + 6 weeks (group 4). The overall performance CL as a predictive test for PTD was similar in the 4 GA groups, as reflected by the similar degree of correlation between CL with the examination to delivery interval (r = 0.27, r = 0.26, r = 0.28, and r = 0.29, respectively, P = .8), the similar area under the receiver-operator characteristic curve (0.641-0.690, 0.631-0.698, 0.643-0.654, and 0.678-0.698, respectively, P = .7), and a similar decrease in the risk of PTD of 5-10% for each additional millimeter of CL. The optimal cutoff of CL, however, was affected by GA at presentation, so that a higher cutoff of CL was needed to achieve a target negative predictive value for delivery within 14 days from presentation for women who presented later in pregnancy. The optimal thresholds to maximize the negative predictive value for delivery within 14 days were 36 mm, 32.5 mm, 24 mm and 20.5 mm for women who presented at 32 + 0 to 33 + 6 weeks, 30 + 0 to 31 + 6 weeks, 27 + 0 to 29 + 6 weeks and 24 + 0 to 26 + 6, respectively. CONCLUSION: CL has modest predictive accuracy in women with threatened PTL, regardless of GA at presentation. However, the optimal cutoff of CL for the purpose of clinical decision making in women with PTL needs to be adjusted based on GA at presentation.

OBJECTIVE: To investigate the emotional response in cases of multifetal reduction and pregnancy termination and to compare the psychological response between these two groups. METHODS: A prospective study in a tertiary-care, university-affiliated medical center. The study group included 65 women who had been advised to terminate pregnancy because of a finding of a severe fetal abnormality on ultrasound screening (pregnancy termination group) and 41 women advised to undergo reduction because of the presence of multiple fetuses (multifetal reduction group). All women underwent psychological testing using validated questionnaires addressing perinatal grief and anxiety levels. RESULTS: Women in both the multifetal reduction and the pregnancy termination groups reported significant degree of grief and anxiety before and after the procedure, although the levels of anxiety on the day of procedure and anxiety and grief at follow up were higher in the pregnancy termination group (t = 2.438, p = 0.016; t = 2.441, p = 0.017; and t = 3.111, p = 0.03, respectively). In both groups there was a gradual decrease in the state anxiety with time (48.01 ± 8.26 to 37.59 ± 9.23; t = -9.931; p < 0.001). Several factors affected the emotional response in the cases, including marital status, level of education, employment status, and gestational age. There was no association between a history of prior perinatal loss and emotional response. CONCLUSION: There is need for a continuing psychosocial support of women undergoing multifetal reduction and pregnancy termination for fetal abnormalities.

OBJECTIVES: To analyze the effect of fetal sex on intrauterine growth patterns during the second and third trimesters. METHODS: We conducted a cross-sectional study of women with uncomplicated singleton pregnancies who underwent sonographic fetal weight estimation during the second and third trimesters in a single tertiary center. The effect of fetal sex on intrauterine growth patterns was analyzed for each of the routine fetal biometric indices (biparietal diameter, head circumference, occipitofrontal diameter, abdominal circumference, and femur length) and their ratios. Sex-specific regression models were generated for these indices and their ratios as a function of gestational age. Sex-specific growth curves were generated from these models for each of the biometric indices and their ratios for gestational weeks 15 to 42. RESULTS: Overall, 12,132 sonographic fetal weight estimations were included in the study. Fetal sex had an independent effect on the relationship between each of the biometric indices and their ratios and gestational age. These effects were most pronounced for biparietal diameter (male/female ratio, 1.021) and the head circumference/femur length and biparietal diameter/femur length ratios (male/female ratios, 1.014 and 1.016, respectively). For the head measurements, these sex-related differences were observed as soon as the early second trimester, whereas for abdominal circumference, the differences were most notable during the late second and late third trimesters. CONCLUSIONS: Female fetuses grow considerably slower than male fetuses, and these differences are observed from early gestation. However, the female fetus is not merely a smaller version of the male fetus, but, rather, there is a sex-specific growth pattern for each of the individual fetal biometric indices. These findings provide support for the use of sex-specific sonographic models for fetal weight estimation as well as the use of sex-specific reference growth charts.
