RESUMEN
INTRODUCTION: Studies investigating the risk factors associated with unfavorable maternal/neonatal outcomes in cases of shoulder dystocia are scarce. This study aims to uncover the predictive factors that give rise to unfavorable outcomes within the context of shoulder dystocia. MATERIALS AND METHODS: Medical records of pregnancies complicated by shoulder dystocia was obtained between 2008-2022 from a single tertiary center. This study involved the comparison of sociodemographic, sonographic, and delivery characteristics among pregnancies complicated by shoulder dystocia resulting in favorable vs. unfavorable maternal/neonatal outcomes. RESULTS: A total of 275 pregnancies were analyzed, with 111 (40.3%) classified as unfavorable outcomes and 164 (59.7%) as favorable outcomes. Employing a multivariable regression analysis, several independent associations were identified with unfavorable maternal/neonatal outcomes. Specifically, short maternal stature, pre-gestational diabetes, vacuum extraction, Wood's screw maneuver, and macrosomia merged as significant predictors of unfavorable maternal/neonatal outcomes. CONCLUSION: Short maternal stature, pre-gestational diabetes, vacuum extraction, Wood's screw maneuver, and macrosomia may all contribute to poor maternal/neonatal outcomes in shoulder dystocia cases. This knowledge allows clinicians to improve their decision-making, patient care, and counseling.
RESUMEN
BACKGROUND: Induction of labor with an extra-amniotic balloon catheter is a procedure commonly associated with maternal discomfort, pain, and anxiety. OBJECTIVE: We aimed to investigate the distractive effect of virtual reality technology on pain and anxiety among pregnant patients who underwent induction of labor with an extra-amniotic balloon catheter. STUDY DESIGN: In this randomized controlled trial, pregnant patients who were undergoing planned induction of labor using an extra-amniotic balloon catheter at term for various obstetrical indications were recruited and randomized in a 1:1 ratio into 2 groups. Patients in the virtual reality group were exposed to a virtual reality technology clip (using SootheVR All-In-One virtual reality care system for pain and anxiety) during the entire extra-amniotic balloon catheter insertion, whereas patients in the control group received the institutional standard care for extra-amniotic balloon catheter insertion. Pain scores, expressed as visual analog scale scores, and maternal hemodynamic parameters were obtained before, during, and after extra-amniotic balloon catheter insertion. Anxiety was evaluated using the validated State-Trait Anxiety Inventory Scale before and after the procedure. Maternal satisfaction with the virtual reality technology was also recorded. The primary outcome was the change in visual analog scale score before and during extra-amniotic balloon catheter insertion. Among the secondary outcomes was the change in anxiety levels before and after extra-amniotic balloon catheter insertion. The study was powered to detect a 25% decrease in the primary outcome. RESULTS: A total of 132 pregnant patients were recruited (66 in each group). There were no differences between groups in terms of age, body mass index, gestational age at enrollment, indication for induction of labor, and preprocedural visual analog scale score and anxiety levels. The change in visual analog scale score (maximal visual analog scale score during the procedure minus the initial visual analog scale score before the procedure, ie, the primary outcome) was significantly lower in the virtual reality group than in the control group (2.78±3.0 vs 4.09±2.99; P=.01). In addition, the virtual reality group experienced a higher rate of anxiety relief, expressed as the difference between the preprocedure and postprocedure State-Trait Anxiety Inventory Scale scores (-6.46±9.6 vs -2.01±9.11; P=.007). Patients in the virtual reality group reported a very high overall (94%) satisfaction score. CONCLUSION: In this randomized controlled trial, we demonstrated that the use of virtual reality technology among patients who underwent induction of labor using an extra-amniotic balloon catheter was associated with lower visual analog scale scores during the procedure and a significant reduction in anxiety than patients who received standard care. There was also a very high satisfaction rate with the use of virtual reality technology.

INTRODUCTION: Inflammation and acidosis are two stress stimuli that correspond to pathophysiological processes occurring in placental-mediated vascular disorders. We aimed to investigate the effects of these stimuli on placental chorionic blood vessels reactivity using the ex-vivo placental perfusion model. METHODS: Term placentas were obtained immediately after cesarean deliveries, and selected cotyledons were cannulated and dually perfused ex-vivo. Placentas were perfused with three different protocols: culture medium (M199-controls, n = 5), culture medium with lipopolysaccharide (inflammatory stimuli) (LPS,1 µg/ml, n = 7), and acidotic culture medium (M - 199, pH: 6.9-7, n = 6). Each perfusion experiment was maintained for 180 min. Fetal perfusion pressure was continuously measured. Measurements in response to angiotensin II (AT II) at the end of the perfusion were compared between the treatment groups, including amplitude of the contraction response, relaxation factor, time to maximal constriction and the area under the pressure curve (AUC). RESULTS: In response to ATII there was a significant difference in the amplitude of the contraction and the AUC between the treatment groups, (p = 0.049, p = 0.015, respectively). As compared with control perfused cotyledon, the inflammatory stimuli significantly increased the vasoconstriction response to ATII in fetal placental blood vessels, as expressed by increased AUC - median (IQR): 555 (235-1184) vs. 133 (118-207), respectively, p = 0.017. The time to maximal constriction and the relaxation factor did not differ between the groups. DISCUSSION: Inflammatory stimuli but not acidosis impact fetal-placental vasculature in response to ATII, suggesting that inflammation can compromise vascular function.

INTRODUCTION: Growth discordancy in dichorionic diamniotic (DCDA) twin gestations is a known complication associated with adverse neonatal outcomes. We aimed to study the differences in placental pathology, in relation to fetal sex, in DCDA twin gestations complicated with growth discordancy. METHODS: The medical files of all DCDA twin deliveries complicated by growth discordancy between 2010 and 2020 were reviewed. Growth discordance was defined as a gap between twin birthweights > 20%. A comparison was made between female vs. male growth discordant twins. Placental lesions were classified as lesions related to maternal or fetal malperfusion lesions (MVM, FVM), vascular and villous changes, and inflammatory lesions. RESULTS: Included 174 DCDA twins. Eighty-eight were in the discordant female group and eighty-six in the discordant male group. The groups did not differ in maternal demographics, pregnancy characteristics, and neonatal outcome. The discordant male group had a higher rate of placental MVM lesions as compared to the discordant female group (p = 0.003). The increased rate of placental MVM lesions in the discordant male group compared to the discordant female group did not change whether its co-twin was of similar or opposite sex. DISCUSSION: Higher rate of MVM lesions characterizes growth discordant male neonates in DCDA twin gestations. This finding could represent a different adaptation of male fetuses to a hostile intrauterine environment.

We aimed to compare obstetric and perinatal outcomes of in vitro fertilization (IVF) pregnancies following fresh and frozen embryo transfer (FET). This was a historic cohort of deliveries between November 2008 and January 2020 at a single university hospital, in which each fresh transfer IVF pregnancy was matched to a FET pregnancy by the same woman (1:1 ratio). We included live singleton deliveries (> 24 weeks of gestation) and excluded pregnancies following egg donation. The primary outcome was birthweight, and secondary outcomes were small for gestational age (SGA) neonates and preterm birth (PTB). A total of 107 fresh transfer pregnancies were matched to 107 FET pregnancies, in the same women. Mean maternal age was lower in the fresh transfer group compared to the FET group (30.4 vs. 32.5 years, p < 0.001). A higher rate of nulliparity was noted in fresh transfer pregnancies (64.5% vs. 12.1%, p < 0.001). Mean birthweight was non-significant between the groups (p = 0.13), and the rates of low birthweight and small for gestational age neonates did not differ between the groups. Preterm deliveries occurred in 10.3% and 9.3% of fresh transfer and FET pregnancies respectively, p = 0.79. On multivariate linear regression analysis, the type of embryo transfer-FET or fresh-was not independently associated with birthweight, after adjustment for women's age, nulliparity, and BMI. IVF pregnancies following fresh and FET entailed the same obstetric and perinatal outcomes when compared in the same women.

BACKGROUND: Human milk lactation provides health benefits for both the mother and infant. Patients commonly report stopping breastfeeding sooner than they planned. Interventions with proper accessible counseling and support to the mother can potentially increase lactation rates and duration. OBJECTIVE: This study aimed to investigate the impact of introducing a smartphone-based daily feedback and counseling platform between women after delivery and a multidisciplinary lactation support team on lactation rates and various maternal and neonatal outcomes. Counseling was provided via a specifically developed application from a multidisciplinary team (obstetricians, nurses, lactation counselors, and psychologist) in an attempt to assist and counsel to maintain lactation. STUDY DESIGN: This was a prospective, single-center, randomized controlled trial. Women planning to lactate were recruited at postpartum day 1 and were randomized to (1) routine lactation counseling and support (control group) or (2) additional daily detailed counseling and feedback on lactation from the team via the application (App group). The primary outcome was partial or full lactation at 3 months after delivery. The secondary outcomes included lactation at additional time points up to 6 months after delivery. The study was adequately powered to detect a 15% difference in the primary outcome. RESULTS: A total of 197 patients were recruited, 97 in the App group and 100 in the control group. The 2 groups did not differ in any background or delivery characteristics. The App group showed higher rates of lactation 6 weeks after delivery (96.9% vs 82.0%; P<.001) and 3 months after delivery (81.4% vs 69.0%; P=.049) than the control group. Patients in the App group reported excellent satisfaction from the use of the application and their overall postnatal care. CONCLUSION: Our study has provided further information on the growing efficacy of technology platforms in obstetrical care. The introduction of a smartphone-based daily feedback and counseling platform between postpartum patients and a multidisciplinary lactation support team increased the lactation rates after delivery with excellent patient satisfaction.

PURPOSE: A growing body of evidence accumulate pointing to sex-specific differences in placental adaptation to pregnancy complications. We aimed to study if there is a difference in placental histopathology lesions, between female and male fetuses in pregnancies complicated with preeclampsia. METHODS: The medical files of all patients with preeclampsia, were reviewed. Placental lesions were classified to lesions related to maternal or fetal malperfusion lesions (MVM, FVM), vascular and villous changes, and inflammatory lesions. Comparison was performed between the male and the female groups. RESULTS: The study included 441 preeclamptic patients. Women in the male preeclampsia group (n = 225) had higher rate of chronic hypertension (p = 0.05) and diabetes mellitus (p < 0.005), while women in the female preeclampsia group (n = 216) had higher rate of thrombophilia. There were no between groups differences in neonatal outcome or placental histopathology lesions. The early preeclampsia cohort included 91 patients. Placentas from the female early preeclampsia group (n = 44) had more vascular changes related to MVM lesions (decidual arteriopathy), as compared to the male early preeclampsia group (n = 47), 50% vs. 25%, p = 0.01. CONCLUSIONS: Higher rate of placental MVM lesions in the female as compared to male group correspond with sex-specific difference of placental pathophysiological adaptation, in early preeclampsia.

INTRODUCTION: We aimed to assess trial of labor rates in patients in their second pregnancy following a cesarean delivery (CD), and asses the correlation to delivery and postpartum characteristics of their primary delivery. MATERIALS AND METHODS: This was a retrospective cohort of deliveries at our institution between 2009 and 2016. Files of patients with one past CD and a subsequent second delivery were reviewed. Included were patients with a favorable past indication for CD - malpresentation, nonreassuring fetal heart rate, multiple gestation, or placenta previa/abruption. Cases in which a TOLAC was undertaken were compared to those who did not undergo a TOLAC regarding maternal, obstetric, and neonatal outcomes. RESULTS: Five hundred and thirty-six deliveries matched the inclusion criteria, in which 269 patients attempted a TOLAC (TOLAC group) and 267 patients did not (no TOLAC group). Patient demographics at the time of primary CD were similar, but the rate of preterm deliveries was higher among the no TOLAC group. In their second delivery, patients who attempted a TOLAC were younger, had a lower body mass index, had a lower rate of assisted reproduction, and has less pregnancy-related complications (diabetes, hypertensive disorders). CONCLUSIONS: In patients with a first CD, a history of preterm delivery negatively correlated with a TOLAC, while patient age, body mass index and gestational comorbidities negatively affected TOLAC rates in subsequent delivery.

BACKGROUND: Antenatal detection of abdominal circumference (AC) <10th percentile, among small for gestational age (SGA) neonates, probably reflects the severity of their growth restriction. We aimed to study neonatal outcome and placental pathology among SGA neonates in correlation to their AC measurements. METHODS: Maternal and neonatal computerized medical records and placental histopathology reports of all SGA neonates, (neonatal birth-weight ≤10th percentile), born between 24 and 42 weeks, during 2015-2018 were reviewed. Included cases with fetal biometric measurements conducted up to 7 days prior labor. Results were compared between cases with sonographic antenatal AC <10th percentile and neonates with sonographic antenatal AC ≥10th percentile. Placental lesions were classified according to "Amsterdam" Placental workshop criteria. RESULTS: The AC <10th percentile group (n = 148) was characterized by higher rate of nulliparity (p = .003), and induction of labor (p = .009), as compared to the AC ≥10th percentile group (n = 41). There were no between groups differences in the rate of maternal BMI (kg/m2), hypertensive disorders, diabetes or smoking. Neonatal hypoglycemia was more common in the AC <10th percentile group as compared to the AC ≥10th percentile group (p = .04). Placentas from the AC <10th percentile group were smaller (p < .001), with more MVM lesions (p = .02) and chronic villitis (p = .04). By multivariate regression analysis, AC <10th percentile and maternal hypertensive disorders, were found to be independently associated with placental MVM lesions, aOR = 2.43 (95% CI 1.04, 5.88) and aOR = 3.15 (95% CI 1.06, 9.31), respectively. CONCLUSIONS: Higher rate of placental maternal malperfusion lesions, chronic villitis, and more neonatal hypoglycemia characterize SGA neonates with AC <10th percentile, pointing to the importance of AC measurement as an indicator for placental insufficiency.

OBJECTIVE: To investigate the association between gestational impaired glucose tolerance (GIGT), and laboratory and clinical hyperglycemic markers. METHODS: A prospective study in Holon between 2017 and 2019. Women with a singleton term delivery and one abnormal value in their last three oral glucose tolerance test measurements (OGTTs; GIGT group, n = 60) were compared with control women with normal glucose challenge test (GCT) and/or OGTT measurements (n = 60). Primary outcomes were elevated cord-blood C-peptide (>90th percentile), maternal hemoglobin A1c (HbA1c), abnormal HbA1c (>5.7%), and neonatal skinfold thickness. Secondary outcomes included large for gestational age (LGA). RESULTS: Women in the GIGT group were older (33.3 ± 5.3 vs 31.1 ± 4.8 years; P = 0.019), and had a higher rate of LGA (26.7% vs 6.7%; P = 0.005), macrosomia (13.3% vs 0%; P = 0.006), elevated C-peptide (16.7% vs 1.7%, P = 0.008), and abnormal HbA1c (13.3% vs 0%, P = 0.006). Skinfold thickness was also significantly higher in the GIGT group. HbA1c (adjusted odds ratio [aOR], 10.48; 95% confidence interval [CI], 1.19-91.91; P = 0.033) and GIGT (aOR, 11.43; 95% CI, 1.78-73.39; P = 0.01) were independently associated with LGA. CONCLUSION: Women with GIGT on OGTT demonstrated "hyperglycemic characteristics" relative to those with normal GCT and/or OGTT.

OBJECTIVES: The aim of this study is to assess the procedure-to-delivery interval (PDI), the obstetric complications, and the early neonatal outcome in patients that did or did not receive glucocorticosteroids (GCSs) before third-trimester amniocentesis (TTA). METHODS: A retrospectively analysis of 445 TTA procedures divided into two groups based on the administration (study group = 220 patients) or not (control group = 225 patients) of GCSs before TTA. The PDI was calculated for all patients. Obstetric and neonatal outcomes were compared between the groups. RESULTS: The rate of procedure-associated complications was similar between the groups. The mean PDI was 47.2 ± 16.8 days. The overall incidence of preterm birth was 11.7%; 9% delivered between 34 and 37 weeks and 2.7% between 28 and 34 weeks. Only nine patients (2%) delivered within seven days following TTA. The incidence of respiratory distress syndrome in the study and control groups was 1.8% and 1.3%, p = .71, respectively. There were no significant differences in other neonatal outcomes in term and preterm deliveries between the study and control groups. CONCLUSIONS: In the present study, the administration of glucocorticoids prior to TTA did not reduce the rates of neonatal complications, which was similar in both groups and not higher than the general population.

OBJECTIVE: We aimed to study the effect of preemptive local anesthetic without adrenaline on postoperative pain following vaginal hysterectomy and concomitant trans obturator tape (TOT). STUDY DESIGN: This was a double-blinded, randomized, controlled trial. Women who undergone elective vaginal hysterectomy were included. Solutions of either Bupivacaine-Hydrochloride 0.5%, or Sodium-Chloride 0.9% as a placebo, were prepared prior to surgery, according to randomization. The chosen solution was injected before incision, in a circumferential manner, to the cervix. The amount of fluid administered was 10 ml. When colporrhaphy was also performed, an additional 5 ml of solution were injected in the midline of the vaginal wall prior to each incision line. We conformed to the CONSORT recommendations. By utilizing the 10 cm Visual-analogue-scale (VAS) we assessed post-operative pain at rest at 3, 8, and 24 h, and during ambulation at 8 and 24 h. We estimated that the intervention would cause a 25% reduction in the primary outcome. The required total sample size was calculated to be 30 patients women for each group. We used ANOVA for continuous variables and the Chi-square or Fisher exact tests for categorical variables. RESULTS: A total of 30 women were included in each group. The level of postoperative pain, as assessed by VAS, was not significantly different between the groups, in all points of time. In addition, there was no difference between the groups in opioid based analgesics during recovery, nor in postoperative analgesic use. CONCLUSION: Preemptive local anesthesia was not shown to be efficient in reducing postoperative pain after vaginal hysterectomy and TOT.

Barker pioneered the idea that the epidemic of coronary heart disease in Western countries in the 20th century, which paradoxically coincided with improved standards of living and nutrition, has its origin in fetal life. Indeed, there is substantial evidence associating low birthweight because of fetal growth restriction with an increased risk of vascular disease in later adult life. These conclusions led to the second part of the Barker hypothesis, the thrifty phenotype, in which adaptation to undernutrition in fetal life leads to permanent metabolic and endocrine changes. Such changes are beneficial if the undernutrition persists after birth but may predispose the individual to obesity and impaired glucose tolerance if conditions improve. The hypothesis assumes that a poor nutrient supply during a critical period of in utero life may "program" a permanent structural or functional change in the fetus, thereby altering the distribution of cell types, gene expression, or both. The fetus, in response to placental undernutrition and to maintain sufficient vascular supply to the brain, decreases resistance to blood flow in the middle cerebral artery. Simultaneously, because of the limited blood supply to the fetus, the arterial redistribution process is accompanied by increased resistance to flow to other fetal vital organs, such as the heart, kidneys, liver, and pancreas. It may explain why individuals exposed to ischemic changes in utero develop dyslipidemia, lower nephron number, and impaired glucose tolerance, all factors contributing to metabolic syndrome later in life. Nevertheless, support for the hypotheses comes mainly from studies in rodents and retrospective epidemiologic studies. This review focused on ultrasound and Doppler studies of human fetal growth restriction in several fetal organs: the placenta, fetal circulation, brain, heart, kidneys, adrenal glands, liver, and pancreas. Support for the hypothesis was provided by animal studies involving conditions that create fetuses with growth restriction with effects on various fetal organs and by human studies that correlate impaired fetal circulation with the in utero development and function of fetal organs.

OBJECTIVE: We aimed to investigate the likelihood of vaginal colonization with Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pregnant and non-pregnant women with Coronavrus Disease 2019 (COVID-19). MATERIALS AND METHODS: Vaginal swabs were taken from women diagnosed with mild to moderately acute SARS-CoV-2 infection, at Wolfson Medical Center, Israel, from March 2020 through October 2020. COVID-19 was diagnosed by real-time polymerase chain reaction (RT-PCR) performed on nasopharyngeal swabs. Vaginal swabs were tested for the presence of SARS-CoV-2 by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: In total, 51 women diagnosed with COVID-19 were included in the study. Of the 51 women with COVID-19 enrolled in this study, 16 (31.4%) were pregnant at enrollment and 35 (68.6%) were non-pregnant. Mean age was 43.5 ± 15.3 years (range 21-74 years). Compared to the non-pregnant group, the pregnant group was characterized by a higher white blood cell and absolute neutrophil count (p = 0.02 and p = 0.027, respectively). The non-pregnant patients were more likely to have chronic diseases (p = 0.035) and to be hospitalized (p < 0.001). Only one patient (1.9%) aged 60 years tested positive for SARS-CoV-2 in vaginal secretions. Mean gestational age at the diagnosis of COVID-19 of the pregnant group was 32.3 ± 7.8 weeks. Thirteen patients delivered during the study period; all delivered at term without obstetric complications and all neonates were healthy. CONCLUSIONS: Detection of SARS-CoV-2 in the vaginal secretions of patients diagnosed with COVID-19 is rare. Vaginal colonization may occur during the viremia phase of the disease, although infectivity from vaginal colonization needs to be proven.
RESUMEN
INTRODUCTION: We aimed to investigate the effect of maternal passive smoking (MPS) during pregnancy-on placental pathology and pregnancy outcomes. METHODS: A prospective case-control study. We recruited low-risk laboring women at 37+0-41 + 0 weeks between 9/2019-7/2020. MPS was defined as exposure to in-house spouse tobacco smoking of >20 cigarettes/day in the absence of maternal active-smoking. In attempt to "purify" the effect of MPS on placental pathology-we excluded cases with preeclampsia, diabetes, suspected fetal growth restriction (FGR), preterm labor, and illicit drug use. Maternal characteristics, pregnancy outcomes, and placental pathology were compared between the MPS group and a control group matched for gestational age, maternal age, and delivery date. Placental lesions were classified according to the "Amsterdam" criteria. The study was powered to detect a 33% difference in placental malperfusion lesions. Multivariable regression was performed to identify independent associations with placental malperfusion lesions. RESULTS: In labor, the MPS group (n = 115) had higher rates of meconium stained amniotic fluid (MSAF, p < 0.001) and non-reassuring fetal heart-rate (NRFHR,p = 0.006), compared to controls (n = 115). Neonates in the MPS group had higher rates of undiagnosed FGR (p = 0.01) and NICU admissions (p = 0.004). The MPS group had higher rates of placental-hypoplasia (p = 0.02) and fetal vascular malperfusion (FVM) lesions (p = 0.04). In regression analysis MPS was associated with FVM lesions independent of background confounders (aOR = 1.24 95% CI 1.10-2.65). DISCUSSION: In otherwise low-risk pregnancies, MPS was associated with higher rates of MSAF, NRFHR, undiagnosed FGR, and NICU admissions, probably mediated via placental FVM. These worrisome findings mandate patient counseling and further investigation in larger population-based studies.

OBJECTIVES: The angle between the inter-ventricular septum and the ascending aorta can be measured during a sonographic fetal survey while viewing the left ventricular outflow tract (LVOT angle). Our aim was to compare the LVOT angle between fetuses with and without conotruncal cardiac anomaliesrmations. METHODS: In this prospective observational study, we compared the LVOT angle between normal fetuses, at different gestational age, and fetuses with cardiac malformations. RESULTS: The study included 302 fetuses screened at gestational age of 12-39 weeks. The LVOT angle ranged from 127 to 163 degrees (mean 148.2), in 293 fetuses with normal hearts, and was not correlated with gestational age. The LVOT angle was significantly wider in fetuses with D-transposition of the great arteries (D-TGA, eight fetuses) and valvar aortic stenosis (AS, three fetuses), than in fetuses with normal hearts (164.8 ± 5.0 vs. 148.2 ± 5.4, respectively, p < 0.001). Conversely, the LVOT angle was significantly narrower in fetuses with complete atrioventricular canal defect (AVC, eight fetuses), than in fetuses with normal hearts (124.8 ± 2.4 vs. 148.2 ± 5.4, respectively, p < 0.001). On ROC analysis, an angle of 159.6 degrees or higher had a sensitivity of 100% and a specificity of 97.3% for the detection of TGA or AS, whereas an angle of 128.8 degrees or lower had a sensitivity of 100% and a specificity of 99.7% for the detection of AVC defect. CONCLUSIONS: The LVOT angle is constant during pregnancy, and differs significantly in fetuses with TGA/AS, and AVC, compared to fetuses with normal hearts (wider and narrower, respectively).
RESUMEN
INTRODUCTION AND HYPOTHESIS: Following vaginal hysterectomy (VH), fixation of the vaginal vault is needed to prevent post-operative recurrence/exacerbation of vault prolapse. The effectiveness of McCall culdoplasty in cases of advanced prolapse is unclear. We aimed to compare the effectiveness of McCall culdoplasty following VH in patients with mild versus advanced stages of uterine prolapse. METHODS: In this retrospective study, the Pelvic Floor Distress Inventory (PFDI-20) was utilized to compare the subjective results of vaginal hysterectomy plus McCall culdoplasty between women with mild uterine prolapse stage 2 (mild prolapse group) and advanced uterine prolapse stages 3-4 (advanced prolapse group). The primary outcome, the subjective awareness of prolapse, was analyzed as well as all other aspects of PFDI-20. A sample size of 130 was calculated. RESULTS: The mild prolapse group consisted of 26 (19.3%) patients and the advanced prolapse group consisted of 109 (80.7%) patients. There were no differences between the groups in demographic and clinical characteristics. The rates of concomitant prolapse and incontinence surgeries, performed at the time of VH and post-operative complications. were the same between groups. The mean follow-up was more than 5 years in both groups. Awareness of prolapse was similar between the groups (11.5% in the mild prolapse group and 5.5% in the advanced prolapse group, p = 0.374). There was no significant correlation between the stage of apical prolapse before surgery and awareness of prolapse after the surgery (r = 0.0132, p = 0.879). All aspects of the PFDI-20 questionnaire were similar in the two groups. CONCLUSION: McCall culdoplasty was found to have an equal subjective effectiveness following VH in both mild and advanced stages of uterine prolapse.

BACKGROUND: Traditionally, the diagnosis of preeclampsia requires elevated blood pressure measurements and proteinuria demonstrated in a 24-hour urine collection. This prolonged urine collection is associated with patient discomfort, a delay in diagnosis, and in some cases, hospitalization for further management of outcomes. OBJECTIVE: We aimed to assess the feasibility, reliability, and association between maternal and neonatal outcomes of pregnancies managed according to a 6-hour vs 24-hour urine protein collection for suspected preeclampsia. STUDY DESIGN: This was a randomized controlled trial conducted at a tertiary university hospital between January 2019 and January 2021 (ClinicalTrials.gov Identifier: NCT03724786). Patients who were hospitalized for preeclampsia workup were asked to participate and randomized at a 1:1 ratio to 6- and 24-hour urine protein collection groups. Both groups collected urine for 24 hours, during which the collection was also tested after 6-hours. After 24 hours, both results were reviewed by one of the research staff, and either the 6- or 24-hour collection result was reported to the patient's managing physician and was documented in the patient's medical record. Both patient and the managing physician were blinded to group allocation. Unblinding was undertaken in cases of a discrepancy between the results (1 of 2 results of >300 mg protein), and the results were analyzed by intention to treat. The primary study outcome was defined as a composite of adverse maternal outcomes. The sample size was set empirically as per proof on concept design. RESULTS: During the study period, 115 patients participated in the trial, 101 of whom completed the follow-up and were analyzed-51 in the 6-hour group and 50 in the 24-hour group. Patient demographics were similar between the study groups. Unblinding occurred in 7 cases in the 6-hour group, in which the initial 6-hour result ranged from 168 to 475 mg. The rates of composite adverse maternal outcomes were 15.6% and 12.0% in the 6- and 24-hour groups, respectively (P=.59). No significant difference was demonstrated in the rate of adverse neonatal outcomes, cesarean delivery, induction of labor, gestational age at delivery, betamethasone treatment, or neonatal birthweight. CONCLUSION: Managing pregnancies suspected of preeclampsia with a 6-hour urine protein collection is feasible and associated with similar maternal and neonatal outcomes. In cases where the 6-hour result is in the 168 to 475 mg range, we propose completing a 24-hour collection.

The uterine location of placenta previa (PP), anterior vs. posterior has an impact on pregnancy outcome. We aimed to study maternal and neonatal outcome and placental histopathology lesions in anterior vs. posterior PP. The medical records and histopathology reports of all singleton cesarean deliveries (CD) performed due to PP, from 24 to 41 weeks, between 12.2008 and 10.2018, were reviewed. Placental lesions were classified into maternal and fetal vascular malperfusion lesions (MVM, FVM), maternal and fetal inflammatory responses (MIR, FIR). Gestational age (GA) at delivery was similar between the anterior PP (n = 67) and posterior PP (n = 105) groups. As compared to the posterior PP group, the anterior PP group had higher rate of previous CD (p < 0.001), placental accreta spectrum (p = 0.04), lower neonatal Hb at birth (p = 0.03), higher rate of neonatal blood transfusion (p = 0.007) and prolonged maternal hospitalization (p = 0.02). Placentas from the anterior PP group had lower weights (p = 0.035), with increased rate of MVM lesions (p = 0.017). The anterior PP location is associated with increased adverse maternal and neonatal outcome, lower placental weights and increased rate of malperfusion lesions. Abnormal placentation in the scarred uterine wall probably has an impact on placental function.
