RESUMEN
OBJECTIVE: Early diagnosis of retained products of conception (RPOC) is critical for directing clinical management and for preventing associated complications. This study aimed to evaluate the utility of post-delivery ultrasound in patients with risk factors for RPOC. STUDY DESIGN: A retrospective cohort-study was conducted in a single tertiary university-affiliated hospital (January 2016-September 2022). Sonographic evaluation, including endometrium thickness measurement and color Doppler, were reviewed of women with risk factors for RPOC: postpartum hemorrhage, a hemoglobin drop > 4 g/dl, manual removal of the placenta, and suspicious placenta. Results of early postpartum ultrasound (within 48 h), misoprostol administration and hysteroscopies were evaluated. RESULTS: Of the 591 women included, RPOC was suspected in 141 (24%). Endometrial thickness > 5 mm was associated with sonographic RPOC diagnosis in 58%. Suspected sonographic RPOC was concluded for 100%, 92% and 7% of the women with marked, moderate, and undetectable vascularity, respectively, p < 0.001. Misoprostol 1000 mcg per rectum (PR) was administered to 86% of those with suspected RPOC; only 11% of them needed an operative hysteroscopy for removal of the RPOC. RPOC on a pathology report was confirmed for 71% of those who underwent hysteroscopy. CONCLUSIONS: Postpartum transabdominal ultrasonography within 48 h of delivery was effective for assessing RPOC. For appropriate triage, color Doppler grading increased the accuracy of RPOC diagnosis. Misoprostol treatment was successful in 88% of women with suspected sonographic RPOC. The combination of sonographic evaluation and misoprostol treatment for suspected RPOC might lower the rate of unnecessary invasive procedures.
RESUMEN
PURPOSE: To examine maternal, obstetrical, and neonatal outcomes of pregnancies complicated by major fetal anomalies. METHODS: A 10 year retrospective cohort study at a tertiary university hospital compared maternal and obstetrical outcomes between women with singleton pregnancies complicated by major fetal anomalies, and a control group with non-anomalous fetuses. RESULTS: For the study compared to the control group, the median gestational age at delivery was lower: 37.0 vs. 39.4 weeks (p < 0.001); and the preterm delivery rates were higher, both at < 37 weeks (46.2 vs. 6.2%, p < 0.001) and < 32 weeks (15.4 vs. 1.2%, p < 0.001). For the study compared to the control group, the placental abruption rate was higher (6.8 vs. 0.9%, p = 0.002); 87.5 vs. 100% occurred before labor. For the respective groups, the mean gestational ages at abruption were 32.8 ± 1.3 and 39.9 ± 1.7 weeks (p = 0.024); and cesarean section and postpartum hemorrhage rates were: 53.8 vs. 28.3% (p < 0.001) and 11.3 vs. 2.8% (p = 0.001), respectively. For the respective groups, hypertensive disorders of pregnancy rates were 9.5 vs. 2.1% (p = 0.004), stillbirth rates were 17.1 vs. 0.3% (p < 0.001), and neonatal death rates 12.5 vs. 0.0% (p < 0.001). Major fetal anomalies were found to be associated with adverse maternal outcomes (OR = 2.47, 95% CI 1.50-4.09, p < 0.001). Polyhydramnios was identified as an independent risk factor in a multivariate analysis that adjusted for fetal anomalies, conception by IVF, and primiparity for adverse maternal outcomes (OR = 4.7, 95% CI 1.7-13.6, p < 0.001). CONCLUSIONS: Pregnancies with major fetal anomalies should be treated as high-risk due to the increased likelihood of adverse maternal and neonatal outcomes.
RESUMEN
OBJECTIVE: Elevated sperm DNA fragmentation has potential implications for semen quality and fertility. The commonly used sperm chromatin dispersion test offers an indirect estimation but has limitations in terms of bias and variability. This study aimed to assess the reliability of the sperm chromatin dispersion assay for predicting assisted reproductive technology outcomes. MATERIALS AND METHODS: This systematic review included studies published until December 2023 that adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed/MEDLINE, Scopus, and Google Scholar databases were searched. Various assisted reproductive technology outcomes in patients with high (≥ 30%) versus low (< 30%) sperm DNA fragmentation were compared using a sperm chromatin dispersion assay and including a sub-analysis of intracytoplasmic sperm injection versus in vitro fertilization. A comprehensive meta-analysis software facilitated quantitative analysis with statistical comparisons between cases and controls. Interstudy heterogeneity was assessed, and sensitivity and publication bias tests were performed. RESULTS: Of the 199 abstracts assessed, 64 full-text articles were screened, and 44 articles were qualitatively synthesized. Fourteen articles representing 5346 participants were quantitatively analyzed. Using the sperm chromatin dispersion assay, elevated sperm DNA fragmentation was associated with lower fertilization and embryo cleavage rates. Notably, high sperm DNA fragmentation levels did not affect the clinical pregnancy, implantation, miscarriage, or live birth outcomes. Sub-analysis revealed lower fertilization, embryo cleavage, clinical pregnancy, live birth rates, and higher miscarriage rates in the intracytoplasmic sperm injection subgroup only. CONCLUSIONS: The sperm chromatin dispersion assay did not show significant differences in pregnancy or live birth rates between the high- and low-sperm DNA fragmentation groups. Noteworthy, high sperm DNA fragmentation was associated with worse assisted reproductive technology outcomes in the intracytoplasmic sperm injection group. Given the current quality of the evidence, affected by the experimental design and the absence of correction for female factors of infertility, clinicians should be wary of the assay's limited predictive power for pregnancy and live birth outcomes.
RESUMEN
OBJECTIVES: The limited data regarding obstetrical outcomes in multiple pregnancies following both fresh embryo transfer and frozen-thawed embryo transfer (FET), along with the association between multiple pregnancies and increased pregnancy complications compared to singleton pregnancies, highlight the need for research on this topic. Therefore, this study aimed to compare obstetrical and neonatal outcomes of twin pregnancies after fresh embryo transfer versus FET. DESIGN: This was a retrospective single-center study. PARTICIPANTS: There were in vitro fertilization (IVF) dichorionic twin pregnancies ≥23 weeks of gestation during 2010-2022. SETTING: This retrospective study was based on data recorded at Galilee Medical Center, a tertiary-care university-affiliated hospital, Israel. METHODS: We conducted a comparative analysis of obstetrical and neonatal outcomes between IVF dichorionic twin pregnancies after fresh embryo transfer and those after FET. This analysis included variables such as gestational age at delivery, birthweight, preterm birth rates, low birthweight rates, neonatal intensive care unit admissions, and complications related to prematurity. RESULTS: The study included 389 IVF twin pregnancies: 253 after fresh embryo transfer and 136 after FET. Following fresh embryo transfer compared to FET, the mean gestational age at delivery was earlier (34 + 6 vs. 35 + 5 weeks, p = 0.001) and the rate of preterm birth (<37 weeks) was higher (70.4% vs. 53.7%, p = 0.001). This difference in gestational age at delivery remained significant after adjustment for maternal age, parity, and BMI (OR = 2.11, 95% CI: 2.11-3.27, p = 0.001). Similarly, the difference in preterm birth rates remained significant after adjustment of the same variables (p = 0.001). For the fresh embryo transfer compared to the FET group, the mean birthweight was lower (2,179.72 vs. 2,353.35 g, p = 0.003); and low birthweight and very low birthweight rates were higher (71.2% vs. 56.3%, p < 0.001 and 13.5% vs. 6.7%, p = 0.004, respectively). For the fresh embryo transfer compared to the FET group, the proportions were higher of neonates admitted to the neonatal intensive care unit (23.3% vs. 16.0%, p = 0.019), of neonates with respiratory distress syndrome (10.5% vs. 5.9%, p = 0.045) and those needing phototherapy (23.3% vs. 16.0%, p = 0.019). LIMITATIONS: Limitations of the study include its retrospective nature. Furthermore, we were unable to adjust for some confounders, such as the number of eggs retrieved, the number of embryos transferred, and methods for ovarian stimulation or preparation of the endometrium for embryo transfer. CONCLUSIONS: Obstetrical and neonatal outcomes of twin pregnancies were worse after fresh embryo transfer than after FET. The findings support favorable fetal outcomes after FET and support the current trend of shifting from fresh embryo transfer to FET. Prospective studies are needed to support our results.
RESUMEN
OBJECTIVE: To assess the accuracy of diagnosing retained products of conception (RPOC) in symptomatic versus asymptomatic women, and to identify potential divergent ultrasound features between these groups. METHODS: This retrospective study included women aged 17-50 years who underwent hysteroscopy for suspected RPOC during 2018-2021. Clinical and sonographic data were analyzed, and multivariable linear regression models employed, to examine correlations between RPOC and sonographic findings, and to compare diagnostic accuracy between symptomatic and asymptomatic women. RESULTS: Of the 225 women included, 123 (54.7 %) were symptomatic and 102 (45.3 %) were asymptomatic. Hysteroscopy complications were more frequent in asymptomatic women. Regarding sonography, statistically significant differences were not found between the groups in endometrial thickness or uterine fluid presence, but positive Doppler flow was more common in asymptomatic than symptomatic women. Endometrial thickness >1.49 cm demonstrated diagnostic utility, with similar sensitivity and specificity in the two groups. Multivariable models revealed significant associations of RPOC presence with endometrial thickness and Doppler flow in symptomatic women. In both groups, hysteroscopy enhanced diagnostic accuracy, with higher positive predictive values and lower false-positive rates compared to ultrasound alone. CONCLUSION: An endometrial thickness cutoff of 1.49 cm aids diagnosing RPOC. Doppler flow enhances diagnostic value in symptomatic women. Integration of hysteroscopy improves diagnostic accuracy compared to ultrasound alone. Regular sonographic assessment for women with identifiable risk factors assists in RPOC detection irrespective of symptoms.

OBJECTIVES: Heterotopic pregnancy of an intrauterine pregnancy and an interstitial or stump pregnancy after bilateral salpingectomy is a rare complication of in vitro fertilization (IVF) that can lead to severe hemorrhage; prompt identification and management are important. The aim of this paper was to present a case report and an updated literature review of women who had had combined interstitial/stump and intrauterine pregnancies during an in an IVF cycle after total bilateral salpingectomy. MATERIAL AND METHODS: We conducted a search in PubMed for reported heterotopic pregnancy, of a combined intrauterine pregnancy with an interstitial or stump pregnancy, in women who underwent IVF after bilateral salpingectomy. RESULTS: Our search yielded 13 heterotopic pregnancies in women who underwent IVF after bilateral salpingectomy. Forty-six percent of the women had more than two embryos transferred, and all the women had a history of ectopic pregnancies or tubal infertility. Most of the women presented at 6-7 weeks of pregnancy with vaginal bleeding and/or abdominal pain. A ruptured ectopic pregnancy was presented in 42%. Ultrasound was the main diagnostic tool in most cases. Only two women had been medically treated with local KCL or methotrexate, while 83% underwent surgical treatment. Five women had uncomplicated cesarean sections near or at term. CONCLUSIONS: Women with bilateral total salpingectomy remain at risk of heterotopic pregnancy, which poses a diagnostic and treatment challenge. This risk may be reduced by the reduction in the number of transferred embryos in IVF. For those who wish to preserve intrauterine pregnancy, cornual resection can be performed with good prognosis.
RESUMEN
BACKGROUND: Catheter balloon insertion is a common method for cervical ripening and labor induction. Papaverine and its derivatives are musculotropic antispasmodic drugs that directly induce smooth muscle relaxation. Used during childbirth, these drugs have been suggested to shorten the duration of labor. OBJECTIVE: This study aimed to evaluate the effect of administering papaverine before catheter balloon insertion on changes in Bishop scores and on the labor induction-to-delivery interval. STUDY DESIGN: This randomized, double-blinded, placebo-controlled trial was conducted in a single tertiary university-affiliated hospital. Participants were admitted at term for labor induction with an initial Bishop score of ≤6. Participants were randomized to receive 80 mg intravenous papaverine or 0.9% normal saline solution within 30 minutes of Foley catheter balloon insertion. The co-primary outcomes were the difference in Bishop score from before catheter balloon insertion to after removal and the labor induction-to-delivery interval. The secondary outcomes included maternal pain and satisfaction scores, delivery within 24 hours, and neonatal outcomes. Both intention-to-treat and per-protocol analyses were performed. RESULTS: Overall, 110 women were enrolled. In the intention-to-treat analysis, the median difference in Bishop score was greater in the papaverine group than in the placebo group (5 [interquartile range, 1-11] vs 4 [interquartile range, 0-7], respectively; P=.025), and the median catheter balloon insertion-to-delivery interval was shorter in the papaverine group than in the placebo group (21 hours [interquartile range, 6-95] vs 26 hours [interquartile range, 3-108], respectively; P=.031). A higher proportion of women delivered within 24-hours in the papaverine group than in the placebo group (65.5% vs 41.8%, respectively; P=.012). Pain and satisfaction scores, delivery, and neonatal outcomes were similar between the groups. Similar results were found in the per-protocol analysis. CONCLUSION: Papaverine administration before Foley catheter balloon insertion for cervical ripening resulted in improved Bishop scores and shorter catheter balloon insertion-to-delivery intervals.

PURPOSE: To assess a possible association between marked proteinuria and the risk of preeclampsia with severe features, as defined by the American College of Obstetricians and Gynecologists. METHODS: This retrospective study included data recorded at a tertiary university-affiliated hospital between 2017 and 2022. Women at or beyond 24 weeks of gestation with proteinuria (protein levels > 300 mg in a 24 h urine collection) and normal blood pressure during the initial 48 h of admission were included. Obstetrical and neonatal outcomes were compared between women with mild proteinuria (300-1000 mg/24 h) and marked proteinuria (≥ 1000 mg/24 h). RESULTS: Among the women with marked proteinuria (n = 48) compared to those with mild proteinuria (n = 108), the incidences were higher of preeclampsia (50.0% vs. 22.2%, p = 0.001) and of preeclampsia with severe features (18.8% vs. 2.8%, p < 0.001). In multivariate analysis that adjusted for maternal age, primiparity, multiple pregnancy, uric acid level > 6 mg/dL and aspirin treatment, marked proteinuria was a risk factor for preeclampsia with severe features (adjusted odds ratio [aOR] = 10.2, confidence interval [CI] 95% 1.9-54.0, p = 0.007) and for small-for-gestational-age infants (aOR = 2.4, 95% CI 1.02-5.6, p = 0.001). Among women with marked compared to mild proteinuria, rates were also higher of labor induction (58.3% vs. 25.9%, p < 0.001), indicated preterm delivery (41.7% vs. 25.0%, p = 0.04) and admission to the neonatal intensive care unit (44.1% vs. 25.8%, p = 0.017). CONCLUSIONS: Women with marked compared to mild isolated proteinuria showed higher risk of developing preeclampsia with severe features and of delivering small-for-gestational-age neonates.

OBJECTIVE: Our objective was to examine the association between sonographic estimated fetal weight (EFW) and obstetrical and neonatal outcomes in women with neonatal macrosomia. STUDY DESIGN: This study, conducted at a tertiary university-affiliated hospital from 2017 to 2021, compared obstetrical and neonatal outcomes between two groups of women who delivered macrosomic newborns (actual birthweight ≥ 4,000 g): (1) those with EFW ≥ 3,800 g (suspected impending macrosomia) and (2) those with EFW < 3,800 g (unsuspected impending macrosomia). RESULTS: During the study period, 854 women with neonatal macrosomia attempted vaginal delivery. Only 9.2% had a sonographic EFW ≥ 4,000 g. Among women with EFW ≥ 3,800 g (n = 317) compared with EFW < 3,800 g (n = 537), the cesarean delivery (CD) rate was higher (17.0 vs. 10.5%, p = 0.004) and the operative delivery rate was lower (3.2 vs. 0.6%, p = 0.015). Among primiparous women, the CD rate was higher among those with EFW ≥ 3,800 versus <3,800 g (37.3 vs. 23.2%, p = 0.033). EFW ≥3,800 g was associated with CD, regardless of predelivery body mass index, parity, diabetes mellitus, maximal fetal weight at previous deliveries, actual birthweight, and labor induction (p = 0.014). EFW ≥ 3,800 g and diabetes mellitus were independent predictors of CD. Among women with EFW ≥3,800 g and diabetes mellitus, the risk of CD was double that of those without diabetes and with EFW ≥ 3,800 g (31.4% vs. 15.2%, p = 0.02), although their actual birthweights were similar. Obstetrical and neonatal outcomes were similar between those with sonographic EFW ≥ 3,800 and < 3,800 g. CONCLUSION: Larger EFW increased CD risk among pregnancies with actual neonatal macrosomia. Antenatally suspected macrosomia might alter labor management due to concerns for potential complications, especially when associated with primiparity, diabetes mellitus, or maternal obesity. The increase in the CD rate did not show an association with improved maternal and neonatal outcomes. KEY POINTS: · Antenatally suspected macrosomia might alter labor management due to concerns about complications.. · Larger EFW increased cesarean delivery risk among pregnancies with actual neonatal macrosomia.. · The increase in the cesarean delivery rate was not associated with improved outcomes..
RESUMEN
BACKGROUND: Molar pregnancies, encompassing complete and partial moles, represent a rare and enigmatic gestational disorder with potential ethnic variations in incidence. This study aimed to investigate relations of ethnicity with risks of complete and partial molar pregnancies within an Israeli population while accounting for age differences. METHODS: A retrospective study was conducted of data recorded during 2007-2021 in an academic medical center in Israel. The study population comprised 167 women diagnosed with complete or partial moles, for whom data were obtained through histological examination and P57 immunostaining. Maternal age and ethnicity were extracted from electronic medical records. Incidence rates were calculated per 10,000 live births, and a nested case-control study compared demographic characteristics and molar pregnancy incidences between Arab and Jewish women. Statistical analyses included age-adjusted comparisons, relative risk calculations and multivariate logistic regression. RESULTS: The overall risk of molar pregnancy was 22 per 10,000 live births (95% confidence interval [CI] 18-25). Among Arab women, the overall risk was 21 (95% CI 17-25), and for PM and CM: 14 (95% CI 11-17) and 7 (95% CI 5-10), respectively. Among Jewish women, the overall risk was 23 (95% CI 18-29), and for PM and CM: 12 (95% CI 8-17) and 11 (95% CI 7-16), respectively. Among Arab women compared to Jewish women, the proportion of all the partial moles was higher: (65.3% vs. 51.6%, p = 0.05). The incidence of partial mole was higher among Arab than Jewish women, aged 35-39 years (26 vs. 8 per 10,000, p = 0.041), and did not differ in other age groups. After adjusting for age, the relative risk of partial moles was lower among Jews than Arabs (0.7, 95% CI 0.4-1.0, p = 0.053). For Arab compared to Jewish women, the mean age at molar pregnancies was younger: 31.0 vs. 35.1 years. However, other factors did not differ significantly between Arab and Jewish women with molar pregnancies. In multivariate analysis, Jewish ethnicity was significantly associated with a higher risk of complete molar pregnancies (OR = 2.19, 95% CI 1.09-4.41, p = 0.028). CONCLUSION: This study highlights ethnic differences in molar pregnancy risk within the Israeli population. Jewish ethnicity was associated with a higher risk of complete molar pregnancies, while Arab women had a significantly higher risk of partial moles. These findings underscore the need to consider ethnicity when studying gestational disorders. Further research should seek to elucidate the underlying factors contributing to these differences.

OBJECTIVE: To examine the accuracy of sonographic fetal weight to predict birthweight in very preterm infants (<32 weeks), and to compare the accuracy of estimated fetal weight (EFW) between those small for gestational age (SGA) and those appropriate for gestational age (AGA). STUDY DESIGN: A retrospective study was conducted of data recorded between January 2010 and March 2023. Included were women with singleton livebirths at 23+0-31+6 weeks who had an EFW within one week from delivery. Mean percentage error, mean absolute percentage error, and underestimation and overestimation rates were calculated. We compared the accuracy of EFW between SGA and AGA infants. RESULTS: In total, 360 women were included. The mean absolute percentage error was 7.8 % (range 0 %-68.9 %); for 207 (57.5 %) infants the percentage error was within ±10 %. Overestimation error >10 % was observed in 102 (28.3 %) infants and errors >20 % in 34 (9.4 %). Among infants born in the periviable period (23+0 - 25+6 weeks; N = 56), the mean absolute percentage error was 9.8 % (range: 0 %-40.3 %); the value was within ±10 % for only 28 periviable infants (50 %) and exceeded 20 % for 16.1 %. Among SGA compared to AGA infants, the mean absolute percentage error was higher (11.1% vs. 6.6 %, p = 0.035). Overestimation error >10 % was more frequent among SGA than AGA infants (55 (49.1 %) vs. 47 (19.0 %), p < 0.001). In a multivariate logistic regression analysis, SGA status was independently associated with a higher mean percentage error (beta = 0.260, p < 0.001) and an increased risk of an error >10 % (odds ratio = 2.1, 95 % confidence interval 1.2-3.5, p = 0.008). CONCLUSIONS: Sonographic EFW is limited in assessing very preterm infants, particularly those who are SGA or born during the periviable period. These limitations should be considered regarding impending very preterm births and concerns about abnormal fetal growth.
RESUMEN
BACKGROUND: The cavum septi pellucidi (CSP) is a brain-enclosed cavity located on the midline between the two leaflets of the septum pellucidum that separates the lateral ventricles. This structure develops in the fetus from week 18 and can be seen up to week 37 in almost all cases and then begins to disappear. OBJECTIVES: To measure and determine the normative values of the CSP volume in fetuses between 20 to 40 weeks of gestation. METHODS: The study comprised 161 consecutive pregnant women between 20 to 40 weeks of gestation with single viable fetuses. All patients had normal, disease-free pregnancies. Transvaginal or transabdominal ultrasound was used according to the fetal presentation. The fetal head was assessed in mid-sagittal sections. Once the CSP was visualized, its volume was measured using three-dimensional ultrasound with Virtual Organ Computer-aided Analysis software. The width of the CSP was also measured at the biparietal diameter (BPD) plane. RESULTS: Of the 161 fetuses, the CSP volume was measured in 158. In three patients the CSP was not identified. The CSP volume correlated poorly with gestational age (r=0.229) and with the BPD (r=0.295). The mean CSP volume was 0.508 ± 0.372 ml (range: 0.03-1.78 ml). The simple measurement of the CSP width correlated better with gestational age (r=0.535) and the BPD (r=0.484). CONCLUSIONS: The CSP volume had a poor correlation with gestational age; however, the volume did not exceed 2 ml regardless of gestational age. This information can be used to assess pathologies involving the CSP.

Choanal atresia occurs in about 1 in 5000 births and is associated with other structural and genetic abnormalities. Choanal atresia is usually diagnosed postnatally due to respiratory distress, and rarely diagnosed antenatally. Here, a woman with severe polyhydramnios is described, whose fetus was diagnosed antenatally with isolated bilateral choanal atresia, as evident by persistent absence of flow through the nostrils on ultrasound. A literature review is presented of the antenatal findings of choanal atresia, using ultrasound and other imaging modalities. An association of choanal atresia with polyhydramnios should be considered. Examining flow through the fetal nose, using color Doppler, might aid in diagnosing choanal atresia. If this condition is suspected, a detailed ultrasound scan should be done to rule out other anomalies. Fetal magnetic resonance imaging has been suggested as an additional imaging tool in selected patients. Genetic counselling and invasive prenatal testing should be offered.
RESUMEN
INTRODUCTION: The aim of this study was to examine the efficacy of pneumatic compression of the maternal lower extremities in increasing the amniotic fluid index (AFI) in pregnancies complicated by isolated oligohydramnios. METHODS: Women with isolated oligohydramnios (AFI <5 cm) at 32-41 weeks of pregnancy were connected to a sequential compression device for 60 min. Prior and after the application, AFI and the pulsatility index (PI) of a number of arteries were measured. RESULTS: The median (interquartile range) maternal age of the 21 women included was 29 years (26.50-32.00), the median parity was 1 (1-2), and the median gestational age at intervention was 37.60 weeks (37.00-39.40). The median AFI increased after the application from 4.00 (3.62-4.50) to 6.08 cm (4.90-7.03) (p < 0.001). The median PI of the fetal renal artery decreased from 2.30 (2.01-2.88) to 2.26 (1.68-2.71) (p = 0.01). The hourly fetal urine production did not increase. Changes were not significant in the PI of the umbilical artery, the middle cerebral artery, and the bilateral uterine arteries. CONCLUSION: Short-term activation of pneumatic compression on maternal lower extremities could increase the AFI in women with isolated oligohydramnios.

INTRODUCTION AND HYPOTHESIS: The objective was to analyse the risk of significant bacteriuria in repeat urine cultures from pregnant women, following initial mixed bacterial results. METHODS: This retrospective study examined maternal characteristics and clinical features of women who repeated urine cultures due to previous mixed cultures results. RESULTS: Of 262 women included, 80 (30.5%) had negative cultures and 125 (47.7%) had mixed bacterial growth in their repeat cultures. Positive results (≥104 CFU/ml of a urinary pathogen) were obtained for 57 women (21.8% [95% CI 17.1-27.0]). For 37 (14.1%), the repeat specimen grew 104-105 CFU/ml of microorganisms; whereas for 20 women (7.6% [95% CI 4.9-11.3]), it grew ≥105 CFU/ml. Among women with positive (>104 CFU/ml) compared with those with negative or mixed growth, rates of urinary symptoms were higher (38.6% vs 23.4%, p=0.028), abnormal dipstick results (49.1% vs 21.0%, p<0.001) and hydronephrosis, as demonstrated by renal ultrasound (12.3% vs 2.0, p=0.003). In a multivariate logistic regression analysis, hydronephrosis was associated with the occurrence of a positive repeat culture (aOR = 10.65, 95% CI 2.07-54.90). The sensitivity and specificity for predicting a repeat urine culture with ≥105 CFU/ml were 12.9% and 94.3% respectively, for urinary symptoms; and 19.7% and 97.4% respectively, for abnormal dipstick results. CONCLUSIONS: Mixed bacterial growth might represent a true urinary tract infection in a considerable proportion of women who are symptomatic and have an abnormal dipstick urinalysis.

OBJECTIVES: We aimed to examine the diagnostic value of colposcopy in a large cohort of pregnant women with unexplained vaginal bleeding during the second or third trimester. MATERIALS AND METHODS: This retrospective study included women who underwent colposcopy due to vaginal bleeding in the second and third trimesters during 2012-2022 at a tertiary care hospital. Demographics, obstetric data, bleeding characteristics, colposcopy results, cervical cytology testing, a sonogram directed at the placenta, and birth details were collected. RESULTS: In total, 364 women were included. The mean maternal age was 29.7 years and the mean gestational age at examination was 30.7 weeks. Vaginal bleeding was mild in 80.8%, moderate in 14.6%, and severe in 4.7%. Only 3.3% had been vaccinated against human papilloma virus and 25.5% underwent a Pap smear study before pregnancy. Colposcopy diagnosed the bleeding source in 83 women (22.8%). The colposcopic examination revealed vaginal bleeding due to contact bleeding from ectropion in 46 (12.6%), a decidual/cervical polyp in 37 (10.2%), acetowhite epithelium in 12 (3.3%), herpes genetalis in 2 (0.5%), and bleeding from vaginal varices in 2 (0.5%). Of those who were recommended a follow-up examination after the postpartum period, only 49.1% completed such.Among women with compared to without postcoital bleeding ( N = 72), the risk of abnormal colposcopic findings was higher (24 [33.3%] vs 54 [19.7%], p = .017) and the rate of abnormal Pap smear was higher (7 [13.2%] vs 7 [3.2%], p = .008). CONCLUSIONS: Colposcopy can be a valuable diagnostic tool for women with unexplained vaginal bleeding in the second or third trimester.

PURPOSE: About 40% of pregnant women are anemic and at an increased risk for complications. We examined the efficacy of inpatient anemia workup and treatment in pregnant women diagnosed with moderate-severe anemia (hemoglobin < 10 mg/dL), during hospitalization in the late second-trimester and third-trimester. METHODS: This retrospective study, conducted between March 2020 and November 2022, included women at ≥ 24 gestational weeks who were hospitalized due to various indications and diagnosed with anemia (hemoglobin < 10 mg/dL). The study group comprised women who underwent an inpatient anemia workup and initiation of anemia treatment. The comparison group comprised women who did not undergo an inpatient anemia investigation. The primary outcome was the rate of pre-delivery hemoglobin > 11 g/dL. RESULTS: The most frequent etiology of anemia in the study group (n = 188) was iron-deficiency anemia (30.2%), followed by mixed anemia of iron, folate and vitamin-B12 deficiencies (20.7%). In the study vs. the comparison group (n = 179), the rate of pre-delivery hemoglobin > 11 g/dL was higher, and the increase in hemoglobin from intervention to delivery was greater. The ideal timing for anemia intervention for maximizing the increase in pre-delivery hemoglobin was 6-weeks or more prior to delivery. The rates of postpartum hemorrhage and blood transfusions were similar. The rate of postpartum hemoglobin < 10 g/dL was lower in the study than the comparison group. CONCLUSION: Inpatient anemia investigation and treatment resulted in higher peri-delivery hemoglobin. In women randomly diagnosed with anemia at hospitalization, the rate of pre-delivery hemoglobin > 11 g/dL was increased among those who underwent a simple anemia investigation and treatment initiation.

Importance: Uterine rupture is defined as a nonsurgical disruption of all layers of the uterus. Most ruptures occur in the presence of a scar, usually secondary to a previous cesarean delivery. Rupture of an unscarred uterus is rare and is associated with severe maternal and neonatal outcomes. Objective: To outline the literature on potential predisposing factors, clinical findings, and maternal and fetal outcomes of a rupture of an unscarred uterus. Evidence Acquisition: PubMed was searched for the phrases "uterine rupture," "unscarred," and "spontaneous." Individual case reports, retrospective case series, and review articles in English between 1983 and 2020 were included. Results: We found 84 case reports in 79 articles. The mean maternal age was 29.3 (SD, 5.7) years; 38 women (45.2%) were nulliparous. Uterine rupture occurred in 37% of the women at term; in 9.9%, the gestational age was ≤12 weeks. The most common clinical presentations were abdominal pain (77.4%), signs of hypovolemic shock (36.9%), fetal distress (31%), and vaginal bleeding (22.6%). The most common risk factors were the use of uterotonic drugs for induction or augmentation of labor and a prior curettage procedure. The most frequently ruptured site was the body of the uterus. Hysterectomy managed 36.9% of the ruptures. Four women died (4.8%). Perinatal mortality was 50.6%. Perinatal death was higher in developing than developed countries. Conclusions and relevance: Although rare, spontaneous rupture of the unscarred uterus has serious consequences to the mother and the fetus and should be included in the differential diagnosis of acute abdomen in pregnancy.

BACKGROUND: Evidence is inconsistent regarding the impact of late gestational diabetes mellitus (GDM) on perinatal outcomes. OBJECTIVES: To evaluate associations of GDM diagnosed in the third trimester (late GDM) with adverse obstetric and neonatal outcomes. SEARCH STRATEGY: We searched Embase, Medline, and Web of Science from January 1, 1990 to June 16, 2022, for observational studies. SELECTION CRITERIA: Late GDM was defined as a de novo diagnosis, i.e. after a negative screening for diabetes in the second trimester, and at later than 28 weeks of pregnancy. DATA COLLECTION AND ANALYSIS: Each abstract and full-text article was independently reviewed by the same two authors. Quality was assessed with the use of the Newcastle-Ottawa Scale. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random effects model. MAIN RESULTS: Twelve studies were identified as meeting the inclusion criteria, including 3103 patients (571 with late GDM and 3103 controls). Incidences of shoulder dystocia (OR 1.57, 95% CI 1.02-2.42, P = 0.040), 5-minute Apgar score <7 (OR 1.80, 95% CI 1.14-2.86, P = 0.024), cesarean delivery (OR 1.98, 95% CI 1.51-2.60, P < 0.001), and emergent cesarean delivery (OR 1.57, 95% CI 1.02-2.40, P = 0.040) were significantly higher among women with late GDM than among the controls. The groups showed similarity in the rates of fetal macrosomia, large-for-gestational-age fetuses, neonatal hypoglycemia, and hypertensive disorders of pregnancy. CONCLUSIONS: This meta-analysis showed associations of late GDM with increased adverse perinatal outcomes. Prospective studies should evaluate the impact on perinatal outcomes of repeated third-trimester screening for late GDM.
RESUMEN
OBJECTIVE: Defining how pregnant women respond to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and vaccination is critical to optimize vaccination strategies that protect mother and infant at the epidemic. This study aimed to compare anti-SARS-CoV-2-spike immunoglobulin G (IgG) of vaccinated versus infected women and to determine the optimal timing of maternal vaccination during pregnancy at the time of epidemic. STUDY DESIGN: We collected maternal/cord blood at delivery (October 2021-March 2022) and measured anti-SARS-CoV-2-spike IgG geometric mean concentrations (IgG-GMCs) using a quantitative immunoassay. We compared groups according to timing and number of doses and correlated maternal and fetal IgG levels. We described the proportion of women with IgG levels above the 150 AU/mL positivity threshold according to the timing of infection/vaccination and performed a subanalysis for maternal IgG-GMC levels pre- and during the Omicron wave. RESULTS: We included 238 vaccinated women, 125 who received two doses and 113 three doses, and 48 unvaccinated infected women. All groups infected/vaccinated in the second or third trimester had an IgG-GMC above the positivity threshold. Third-trimester vaccination (second/third dose) resulted in higher maternal and cord-blood IgG-GMC compared to the second trimester (maternal-IgG: 102,32 vs. 4,325 AU/mL, p < 0.001; cord-IgG: 12,113 vs. 8,112 AU/mL, p < 0.001). Compared with infected-only women, a higher proportion of vaccinated women with ≥2 doses and their newborns had IgG levels above the positivity threshold at all time points. In vaccinated women, there were higher maternal IgG-GMC levels during the Omicron wave than pre-Omicron. CONCLUSION: At the time of epidemic, receiving an additional COVID-19 vaccine dose in the third trimester resulted in a higher IgG-GMC compared to the second trimester. Relatively higher levels of maternal and cord IgG-GMC were achieved following vaccination than infection. Women infected during or before the first trimester might benefit from an additional third-trimester dose to prevent peripartum infection and to passively immunize their newborn. The higher levels of maternal IgG-GMC in the Omicron period are suggestive of hybrid immunity. KEY POINTS: · Higher maternal anti-SARS-IgGs in vaccinated â infected.. · Higher cord anti-SARS-IgGs in vaccinated â infected.. · Third-trimester vaccine resulted in high-cord IgG levels..
