Maintaining the apex: a novel technique for vault suspension during vaginal hysterectomy.

INTRODUCTION AND HYPOTHESIS: Post-hysterectomy vault prolapse poses significant challenges to patients and surgeons alike. Despite numerous surgical interventions during initial vaginal hysterectomy to counteract this, a comparative analysis of their efficacy is limited. This study introduces a pioneering technique intended to avert vault prolapse during vaginal hysterectomy by harmoniously merging level 1 and level 2 support. METHODS: After obtaining informed consent, we recorded a variation of the McCall technique performed during vaginal hysterectomy and anterior repair. Patient follow-ups were conducted up to 6 months post-operation to evaluate anatomical outcomes and quality of life. RESULTS: A total of 46 women underwent the surgery. Anatomical evaluations at the 6-month mark were commendable, with no recurrence instances. Quality-of-life assessments, using the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12), showcased substantial improvement. CONCLUSION: Our novel approach to vault suspension provides an uncomplicated, easily impartible, surgical procedure utilizing standard sutures. We believe that this approach is both enduring and safe.

Precision in Practice: The Critical Role of Mesh and Procedure Type Specification in Urogynecological Surgeries and Research.

Recently, the debate surrounding the use of mesh in urogynecological procedures has intensified, leading to FDA warnings and heightened safety concerns. This clinical opinion emphasizes the vital need to specify mesh types in these procedures, drawing attention to the risk profiles and clinical outcomes associated with various meshes and the procedures that utilize them. A significant issue identified in contemporary literature is the tendency to group diverse mesh types under the same umbrella, disregarding their unique characteristics and applications. We describe the range of mesh types, their application routes, and associated complications, highlighting the risks of this nonspecific approach to patient safety and informed decision making. We critically examine the generalization of mesh terminology in clinical and research dialogues. Concluding with specific recommendations for health care providers and researchers, the paper advocates for a more nuanced understanding and communication in the field, ultimately aiming to improve patient care and safety in urogynecological practice.

Pelvic floor disorders among amateur runners.

BACKGROUND: Sports and physical activity are known risk factors for pelvic floor dysfunction (PFD). The aim of this study is to examine the impact of amateur running on PFD, quality of life (QoL), and sexual function. METHODS: Amateur runners were contacted through social media. Their PFD, sexual function, and QoL were evaluated by self-reporting validated questionnaires (PFDI-20, PISQ-12, IIQ-7). They were divided by degree of effort into two categories, 'High effort' and 'Moderate effort'. The differences between the two groups were examined by a Mann-Whitney U Test, T-Test, and Chi-square test. RESULTS: 180 women were included. A high incidence of PFD was found among 'High effort' runners in comparison to 'Moderate effort' runners. In addition, women who scored above the median in the PFDI-20 showed significantly greater impairment in QoL and sexual function. Interestingly, the 'High effort' group reported experiencing higher intensity orgasms compared with women in the 'Moderate effort' group. A correlation was also found between the weekly running distance and the intensity of orgasm experienced (P value = 0.004). CONCLUSION: 'High effort' runners present a higher incidence of PFD in comparison to 'Moderate effort' runners. Professional pelvic floor muscle training counselling should be considered even for amateur runners. Future interventional physical therapy studies should be carried out in order to investigate preventative strategies.

Urodynamic insights: exploring the relationship between detrusor overactivity and pelvic organ prolapse in women with urge incontinence.

PURPOSE: Pelvic organ prolapse (POP) and overactive bladder (OAB) commonly affect the aging female population. We aimed to investigate the possible relationship between the two, as reflected by urodynamic studies. METHODS: A retrospective analysis was conducted on women who underwent urodynamic studies at a university-affiliated tertiary medical center from January 2018 to January 2021. Women presenting with urge incontinence and diagnosed with detrusor overactivity (DO) were included in the study. Based on the presence or absence of a modified POP-Q ≥ grade 2, these women were categorized into two groups. Data on general demographics, clinical symptoms, and urodynamic findings were extracted and compared using SPSS. RESULTS: During the study period, 949 urodynamic evaluations were performed. Of these, 303 (31.92%) reported urge incontinence. Out of this subset, 151 (49.83%) were diagnosed with DO. Within this group, 18 (11.9%) had POP, while 134 (88.1%) did not. The POP group had a notably higher incidence of prior vaginal hysterectomy and anterior colporrhaphy (p = 0.02 and p = 0.01, respectively). While most urodynamic parameters were similar between groups, there was a significant increase in hesitancy in the POP group (13 s vs 8 s, p = 0.03). There was a trend indicating a reduced median Q max (12 ml/s vs. 18 ml/s, p = 0.06) and an increased flow time (55 s vs 40 s, p = 0.08) in the POP group. CONCLUSION: The urodynamic profile of the POP group suggests an obstructive voiding pattern. Further longitudinal research is essential to fully understand the relationship between POP and OAB.

Correlation between total deceleration area in CTG records and cord blood pH in pregnancies with IUGR.

PURPOSE: Fetal cardiotocography is the most common method to assess fetal well-being during labor. Nevertheless, its predictive ability for acidemia is limited, both in low-risk and high-risk pregnancies (Nelson et al. in N Engl J Med 334: 613-9, 1996; Rinciples P et al. in Health and Human Development Workshop Report on Electronic Fetal Monitoring : Update on Definitions. no. 2007, 510-515, 2008), especially in high-risk pregnancies, such as those complicated by growth restriction. In this study we aim examine the association between deceleration and acceleration areas and other measure of fetal heart rate in intrapartum fetal monitoring and neonatal arterial cord blood pH in pregnancies complicated by growth restriction. MATERIALS AND METHODS: A retrospective cohort study of 100 deliveries complicated by growth restriction, delivered during 2018, was conducted. Known major fetal anomalies, non-vertex presentation and elective cesarean deliveries were excluded. Total deceleration and acceleration areas were calculated as the sum of the areas within the deceleration and acceleration, respectively. RESULTS: In deliveries complicated by growth restriction, cord blood pH is significantly associated with total deceleration area (p = 0.05) and correlates with cumulative duration of the decelerations (Spearman's rank -0.363, p < 0.05), and total acceleration area (-0.358, p < 0.05). By comparing the cord blood pH in deliveries with a total deceleration area that was above and below the median total deceleration area, we demonstrated a significant difference between the categories. CONCLUSIONS: Cord blood pH significantly correlates with total deceleration area and other fetal monitoring characteristics in neonates with growth restriction. Future studies using real-time, machine-learning based techniques of fetal heart rate monitoring, may provide population specific threshold values that will support bedside clinical decision making and perhaps achieve better outcomes.

Effect of direct oral anticoagulants on bleeding during and after cataract surgery.

PURPOSE: To assess the risk for intraoperative and postoperative ocular bleeding associated with direct oral anticoagulant treatment in patients undergoing phacoemulsification surgery. METHODS: Consecutive patients had phacoemulsification and intraocular lens implantation while taking uninterrupted direct oral anticoagulants (dabigatran, rivaroxaban, or apixaban). Gender and age-matched patients without antithrombotic therapy were used as the control group. Patients were examined one week postoperatively. Intraoperative and postoperative hemorrhagic and non-hemorrhagic complications were assessed. RESULTS: Forty patients (56 eyes) on direct oral anticoagulants and 120 patients (172 eyes) without anticoagulation, at a mean age of 77 years, had phacoemulsification. There was no significant difference between the groups in the rate of intraoperative and postoperative bleeding. One eye (1.8%) in the treatment group and 3 eyes (1.7%) in the control group had hyphema (p = 0.72). No patient had thromboembolic event during or after surgery. CONCLUSIONS: Cataract surgery was safely performed while continuing direct oral anticoagulation.

PGT pregnancies have a similar risk for post-partum complications as naturally conceived pregnancies.

RESEARCH QUESTION: Do preimplantation genetic testing (PGT) pregnancies have higher post-partum complications compared with naturally conceived pregnancies? DESIGN: Retrospective cohort study conducted in 2008-2020 at the Shaare Zedek Medical Center (SZMC), including all patients aged 18-45 years old who conceived following PGT with a singleton live birth >24 weeks. Data were collected from computerized hospital databases and patient files. There were two control groups: (i) pregnancies following IVF-ICSI (intracytoplasmic sperm injection); (ii) four neighbourhood controls for each case delivery (two women delivered before and two after) of women with naturally conceived pregnancies. RESULTS: Overall, 120 PGT, 779 IVF-ICSI and 3507 naturally conceived deliveries were included. Demographic variables were similar apart from slightly higher age in the PGT (P = 0.003) and ICSI (P = 0.002) groups (31.07 ± 4.38 PGT, 31.66 ± 5.03 ICSI, 28.77 ± 5.72 naturally conceived). Composite post-partum placental-related complications (manual lysis of placenta, revision of uterine cavity, haemoglobin drop ≥3 g/dl, post-partum haemorrhage, need for blood transfusion) were more prevalent in both the PGT and IVF-ICSI groups as opposed to naturally conceived (20.0% versus 18.9% versus 10.3%, respectively, P < 0.001, P = 0.007). In a multivariate regression model PGT was not found to be independently associated with composite post-partum placental-related complications (adjusted odds ratio [aOR] 1.44, 95% confidence interval [CI] 0.83-2.15), while IVF-ICSI pregnancies had increased risk (aOR 1.52, 95% CI 1.20-1.97) compared with natural conception. No difference was found between fresh and frozen cycles or between day 3 and day 5 embryo transfer. CONCLUSIONS: PGT pregnancies have a comparable risk of post-partum placental-related complications to naturally conceived pregnancies, unlike IVF-ICSI pregnancies. It is possible that infertility itself is the main mediator for post-partum complications in IVF-ICSI pregnancies.

The association of intrapartum deceleration and acceleration areas with MRI findings in neonatal encephalopathy.

BACKGROUND: Hypoxic-ischemic encephalopathy (HIE) is an important contributor to disability worldwide. The current cardiotocography (CTG) predictive value for neonatal outcome is limited. OBJECTIVE: To assess the association of intrapartum CTG deceleration and acceleration areas with early MRI cerebral pathology in infants with HIE. METHODS: Term and near-term low-risk pregnancies that resulted in HIE, treated with therapeutic hypothermia with sufficient CTG records from a single, tertiary hospital between 2013 and 2021 were enrolled. Accelerations and decelerations areas, their minimum and maximum depths, and duration were calculated as well as the acceleration-to-deceleration area ratio during the 120 min prior to delivery. These data were assessed for associations with higher degrees of abnormality on early MRI scans. RESULTS: A total of 77 infants were included in the final analysis. Significant associations between increased total acceleration area (p = 0.007) and between a higher acceleration-to-deceleration area ratio (p = 0.003) and better MRI results were detected. CONCLUSION: In neonates treated for HIE, acceleration area and acceleration-to-deceleration ratio are associated with the risk of neonatal brain MRI abnormalities. To increase the role of these measurements as a relevant clinical tool, larger, more powered prospective trials are needed, using computerized real-time analysis. IMPACT: The current cardiotocography predictive value for neonatal outcome is limited. This study aimed to assess the association of intrapartum deceleration and acceleration areas with the degree of cerebral injury in early cerebral MRI of neonates with encephalopathy. Lower acceleration area and acceleration-to-deceleration ratio were found to be associated with a higher degree of neonatal brain injury. Brain MRI is a marker of long-term outcome; its association with cardiotocography indices supports their association with long-term outcome in these neonates. Future computer-based CTG area analysis could assist in delivery room decision making to better time interventions and prevent hypoxic-ischemic encephalopathy.

A Scoring System Developed by a Machine Learning Algorithm to Better Predict Adnexal Torsion.

STUDY OBJECTIVE: To establish a clinically relevant prediction score for the diagnosis of adnexal torsion (AT) in women who were operated on for suspected AT. DESIGN: A retrospective cohort study conducted between 2014 and 2021. SETTING: A large tertiary teaching medical center. PATIENTS: Women who underwent urgent laparoscopy for suspected AT. INTERVENTIONS: Analyses included univariate and multivariate models combined with the machine learning (ML) Random Forest model, which included all information available about the women and reported the accuracy of the model and the importance of each variable. Based on this model, we created a predictive score and evaluated its accuracy by receiver operating characteristic (ROC) curve. MEASUREMENTS AND MAIN RESULTS: A total of 503 women were included in our study, 244 (49%) of whom were diagnosed with AT during the surgery, and 44 (8.8%) cases of necrotic ovary were found. Based on the Random Forrest and multivariate models, the most important preoperative clinical predictive variables for AT were vomiting, left-side complaints, and concurrent pregnancy; cervical tenderness and urinary symptoms decreased the likelihood of surgically confirmed AT. The most important sonographic findings that predicted increased risk of surgically confirmed AT were ovarian edema and decreased vascular flow; in contrast, hemorrhagic corpus luteum decreased the likelihood of surgically confirmed AT. The accuracy of the Random Forest model was 71% for the training set and 68% for the testing set, and the area under the curve for the multivariate model was 0.75 (95% confidence interval [CI] 0.69-0.80). Based on these models, we created a predictive score with a total score that ranges from 4 to 12. The area under the curve for this score was 0.72 (95% CI 0.67-0.76), and the best cutoff for the final score was >5, with a sensitivity, specificity, positive predictive value, and negative predictive value of 64%, 73%, 70%, and 67%, respectively. CONCLUSION: Clinical characteristics and ultrasound findings may be incorporated into the emergency room workup of women with suspected AT. ML in this setting has no diagnostic/predictive advantage over the performance of logistic regression methods. Additional prospective studies are needed to confirm the accuracy of this model.

The Correlation between Fetal Monitor Decelerations Area and Neonatal Cord pH among Preeclamptic parturient: an Automated Approach to a Clinical Challenge.

OBJECTIVE: To examine whether a correlation exists between electronic fetal monitoring (EFM) in the final 120 minute prior to delivery and neonatal cord blood pH among parturients with preeclampsia. STUDY DESIGN: A retrospective cohort study of parturients with term and near-term preeclampsia who delivered at Soroka University Medical Center between 2013 and 2020 was conducted. EFM tracings, demographical data, and obstetrical outcomes were retrieved from the patients' electronic medical records. Using MATLAB program, area under the curve (AUC) measurements were applied. Correlation was calculated using the Spearman's correlation coefficient. RESULTS: EFM of 88 parturients with preeclampsia were assessed. A significant negative correlation was demonstrated between cord blood pH and the decelerations AUC, total decelerations duration, and deceleration depth. No correlation was demonstrated between area over the curve (acceleration) and cord blood pH. In a multivariate linear regression, total deceleration AUC was found independently negatively associated with cord blood pH (beta = -0.264, p = 0.011) controlling for second stage of labor duration and induction of labor. CONCLUSION: Among parturients with preeclampsia, EFM indices may assist in the diagnosis of fetal acidemia. Further studies are needed to strengthen and establish the use of electronic EFM in the management of labor and delivery. KEY POINTS: · A negative correlation was demonstrated between cord blood pH and the decelerations AUC.. · Total deceleration AUC was found independently negatively associated.. · Among parturients with preeclampsia, EFM indices may assist in the diagnosis of fetal acidemia..

Covid-19 third vaccination during pregnancy: maternal and neonatal outcomes-a retrospective study.

PURPOSE: To evaluate the impact of Covid-19 (Pfizer-BioNTech BNT162b2) third booster dose vaccination during pregnancy on maternal and neonatal outcomes. METHODS: This is a multicenter, retrospective computerized database study. Parturients who delivered in Israel between August and December 2021 with full records of Covid-19 disease and vaccination status were included. Those who received third booster during pregnancy were compared to those who received two doses of vaccine during pregnancy and to unvaccinated parturients. Various adverse maternal and neonatal outcomes were evaluated. Parturients who were previously positive with Covid-19 PCR swabs during pregnancy or before pregnancy were excluded. Univariate analysis was followed by multivariate analysis. RESULTS: A total of 2583 women were included in the analysis; 626 received the third booster dose of the BNT162b2 Covid-19 vaccine, 1094 received two doses of the vaccine, and 863 unvaccinated women. Maternal and neonatal outcomes were comparable between the study groups. An adjusted multivariable logistic regression analysis demonstrated that receiving the third booster was not associated with an increase in neither composite adverse maternal or neonatal outcome (aOR 0.9; 95% CI [0.65-1.22], p = 0.47; aOR 0.7; 95% CI [0.53-1.035], p= 0.09, respectively) when compared to those who received two doses of the vaccine. However, administration of the third booster dose during pregnancy was associated with a reduced composite adverse neonatal outcome when compared to unvaccinated women (aOR 0.6; 95% CI [0.42-0.86], p = 0.01). CONCLUSION: Receiving the third booster dose of the BNT162b2 Covid-19 vaccine during pregnancy is not associated with an increased risk of any adverse maternal outcomes and may be beneficial for the neonates.

Trial of labor following cesarean in preterm deliveries: success rates and maternal and neonatal outcomes: a multicenter retrospective study.

PURPOSE: To evaluate the rates of vaginal birth after cesarean (VBAC) among parturients attempting preterm trial of labor following a cesarean delivery (TOLAC) vs. term TOLAC. METHODS: A multicenter historic cohort study was conducted at two university-affiliated centers between August 2005 and March 2021. Parturients in their second delivery, attempting TOLAC after a single low segment transverse cesarean delivery were included. We retrospectively examined computerized medical records of all preterm (< 37 weeks) and term (37-42 weeks) births. Multifetal gestations and postterm deliveries (≥ 42 weeks) were excluded. A univariate analysis was conducted, followed by a multivariate analysis. RESULTS: 4865 second deliveries following previous cesarean were identified: 212 (4.4%) preterm and 4653 (95.6%) term. Hypertensive disorders, diabetes and fertility treatments were significantly more prevalent in the preterm group. VBAC rate was significantly lower in preterm group (57.5 vs 79.7%., p < 0.01), including both spontaneous and vaginal-assisted deliveries. In multivariate analysis, preterm TOLAC was independently associated with TOLAC failure [adjusted odds ratio 2.24, [95% confidence interval 1.62-3.09]. Overall, maternal outcomes were favorable. Rates of uterine rupture, re-laparotomy and postpartum hemorrhage were comparable between groups. Neonatal outcomes were less favorable among the preterm group; however, preterm vs. term TOLAC was not associated with low 5 min Apgar score (aOR 1.76, 95% CI 0.92-3.40). CONCLUSION: In our study, VBAC rates were lower in preterm compared to term deliveries. Maternal outcomes were comparable. Neonatal outcomes were less favorable in the preterm group, more likely due to prematurity than delivery mode.

Trial of labor following cesarean in patients with bicornuate uterus: a multicenter retrospective study.

OBJECTIVE: This study aimed to evaluate whether a trial of labor after cesarean delivery (TOLAC) in women with a bicornuate uterus is associated with increased maternal and neonatal morbidity compared to women with a non-malformed uterus. METHODS: A multicenter retrospective cohort study was conducted at two university-affiliated centers between 2005 and 2021. Parturients with a bicornuate uterus who attempted TOLAC following a single low-segment transverse cesarean delivery (CD) were included and compared to those with a non-malformed uterus. Failed TOLAC rates and the rate of adverse maternal and neonatal outcomes were compared using both univariate and multivariate analyses. RESULTS: Among 20,844 eligible births following CD, 125 (0.6%) were identified as having a bicornuate uterus. The overall successful vaginal delivery rate following CD in the bicornuate uterus group was 77.4%. Failed TOLAC rates were significantly higher in the bicornuate group (22.4% vs. 10.5%, p < 0.01). Uterine rupture rates did not differ between the groups, but rates of placental abruption and retained placenta were significantly higher among parturients with a bicornuate uterus (9.8% vs. 4.4%, p < 0.01, and 9.8% vs. 4.4%, p < 0.01, respectively). Neonatal outcomes following TOLAC were less favorable in the bicornuate group, particularly in terms of neonatal intensive care unit admission and neonatal sepsis. Multivariate analysis revealed an independent association between the bicornuate uterus and failed TOLAC. CONCLUSIONS: This study found that parturients with a bicornuate uterus who attempted TOLAC have a relatively high overall rate of vaginal birth after cesarean (VBAC). However, their chances of achieving VBAC are significantly lower compared to those with a non-malformed uterus. Obstetricians should be aware of these findings when providing consultation to patients.

Laparoscopic negative appendectomy during pregnancy is associated with adverse neonatal outcome.

BACKGROUND: The impact on pregnancy of laparoscopy for acute appendicitis is well documented. However, with an accurate pre-operative diagnosis being more challenging in pregnant patients, the incidence of a negative appendectomy (NA) is higher in this cohort. The aim of this study was to evaluate the maternal and neonatal implications of a NA during pregnancy. METHODS: A single center retrospective study between 2004 and 2019 was performed. Pregnant women who underwent laparoscopic appendectomy for suspected appendicitis were identified from which those who had a pathologically normal appendix were selected. The maternal and neonatal outcome of this group were compared with a matched control group of pregnant women who underwent diagnostic laparoscopy for a presumed ovarian torsion in whom no further surgical intervention was performed. Multivariate regression analysis was performed to explore factors that gestational size. RESULTS: Of the 225 pregnant women who underwent laparoscopy appendectomy, a NA was performed in 33 (14.7%). These were compared with 50 pregnant women in the diagnostic laparoscopy group. The former was characterized by higher rate of nulliparity and later gestational age at the time of the surgery (17.8 ± 7.5 vs 11.3 ± 6.3, p < 0.001). Whilst the rate of maternal complications during pregnancy were similar between the groups, NA was associated with significantly lower neonatal birthweights (2733.9 ± 731.1 vs 3200.7 ± 458.5 g, p = 0.002) and a significantly higher risk of small for gestational age (SGA) infants (OR 5.6, 95% CI 1.02-30.9). CONCLUSIONS: Performing a NA during pregnancy is an indicator for perioperative counseling and antenatal follow up.

The association between amateur running with varying degrees of effort and sexual function among women.

INTRODUCTION AND HYPOTHESIS: Sports and physical activity are known risk factors for altered pelvic floor function, which may affect sexual activity. The aim of this study was to examine the impact of amateur running on sexual function. METHODS: Amateur runners were contacted through social media. Their pelvic floor dysfunction (PFD), sexual function and quality of life were evaluated by self-reported validated questionnaires (PFDI-20, PISQ-12, IIQ-7). They were divided by degrees of effort into 'High effort' and 'Moderate effort.' The differences between the two groups were examined by Mann-Whitney U, t and chi-square tests. RESULTS: One hundred eighty amateur runners were included. No significant differences in the sexual function were found between the two groups. The 'High effort' group reported experiencing higher intensity orgasms compared with women in the 'Moderate effort' group, and a correlation was found between the weekly running distance and intensity of orgasm that they experienced (p = 0.004). CONCLUSIONS: High effort physical activity may be associated with improved orgasm, which may be explained by better clitoral circulation and better function of the pelvic floor muscles. Clinicians that treat symptoms related to PFD and sexual dysfunction may raise awareness of the advantages of physical activity and pelvic floor muscle training and rehabilitation, which may improve tone and circulation and hence sexual function.

Association between striae gravidarum and pelvic floor dysfunction symptoms during pregnancy.

INTRODUCTION AND HYPOTHESIS: Striae gravidarum are linear atrophic scars appearing on the abdomen of pregnant women reported to be related to pregnancy-induced changes in the connective tissue. Pelvic floor distress symptoms are also known to be linked to connective tissue weakness. Given that common pathophysiological pathways may play a role in both striae gravidarum and pelvic floor dysfunction symptoms, we sought to examine whether there is a correlation between them during pregnancy. METHODS: A prospective observational study among third-trimester pregnant women who visited a tertiary medical center for routine pregnancy follow-up was conducted by using the Pelvic Floor Distress Inventory (PFDI-20) questionnaire to evaluate pelvic floor distress symptoms and the Davey method for evaluating striae gravidarum severity. Obstetrical characteristics as well as pelvic floor distress symptoms were compared between two groups according to the severity of striae gravidarum. Univariate analysis was carried out using appropriate tests; PFDI scores were compared between the groups using the Mann-Whitney test. RESULTS: Women with striae gravidarum were significantly older (31.06 vs. 28.83 years, p < 0.01), had a lower body mass index (27.5 vs. 30.98, p < 0.01), and gave birth to smaller neonates (3155 vs. 3389 g, p < 0.01). In addition, the overall and median PFDI-20 scores differed between the groups (with severe SG having the highest median score of 20 and those with milder SG having a score of 16 compared to 14 in those without SG). A distinct association between the PFDI-20 score and SG severity was not demonstrated (p = 0.63). CONCLUSIONS: In our population, an association was demonstrated between pelvic floor distress symptoms and the presence of striae gravidarum. However, following a linear regression model, no statistically significant association between SG severity and total PFD-20 score was seen. Our findings strengthen the hypothesis of common connective tissue involvement in the pathophysiology of both conditions.

Outcomes of attempted vaginal births after previous recurrent operative vaginal deliveries: An individual cumulative risk analysis.

BACKGROUND: Data about the risk of recurrence of vacuum extraction (VE) in multiple consecutive deliveries are scarce. We aimed to evaluate the pattern and individual cumulative risk of recurrence of VE in consecutive term deliveries. STUDY DESIGN: A retrospective cohort study based on a validated electronic database at a single center between 2005 and 2019. For the purpose of the study, we focused on consecutive term deliveries of all primiparas (P1) that had a record of at least one additional delivery during the study period. We identified P1 VE deliveries (reference group) and calculated the individual cumulative risk of repeated VE for three consecutive deliveries. Multivariate analysis was conducted adjusting for potential confounders. RESULTS: We identified 35 113 primiparas that met inclusion criteria. The overall VE rate for P1 was 17.9% (6969 parturient). The cumulative rates of repeated VEs at the 2nd, 3rd, and 4th deliveries were 8.6%, 26.8%, and 25.0%, respectively. The risk of recurrent VE for each of the consecutive deliveries was confirmed after adjustment for confounders (aOR [95% CI]: 5.8 [4.76-7.04], 34.2 [18.59-62.81], and 113.9 [9.77-1328.69] for the 2nd, 3rd, and 4th consecutive deliveries, respectively). CONCLUSION: Women with VE at the first and second deliveries have a substantially increased risk of VE in their following deliveries; this finding may influence woman's preference when choosing future mode of delivery.

Trend Changes in the individual contribution of risk factors for postpartum hemorrhage over more than two decades.

OBJECTIVE: Postpartum hemorrhage is an obstetric emergency with a rising incidence. The aim of this study was to identify trends in the specific contribution of various risk factors for postpartum hemorrhage by observing their odds ratios throughout different time periods. STUDY DESIGN: In this population-based retrospective cohort study trends of change in odds ratios for known risk factors for postpartum hemorrhage occurring in three consecutive eight-year intervals between 1988 and 2014 were compared. Two multivariable logistic regression models were used in order to identify independent risk factors for postpartum hemorrhage in our population. Trends of various risk factors were compared along the time period of the study. RESULTS: The incidence of postpartum hemorrhage increased from 0.5% to 1988 to 0.6%. Using logistic regression models, preeclampsia, vacuum extraction delivery, retained placenta, perineal or vaginal tears and delivery of a large for gestational age neonate were recognized as independent risk factors for postpartum hemorrhage. While the odds ratios for perineal or vaginal tears significantly increased, odds ratios for delivery of a large for gestational age neonate significantly decreased. Odds ratios for the other risk factors did not change significantly. CONCLUSION: In our study, not only did the rates of statistically significant risk factors for postpartum hemorrhage change during the study period, the specific contribution of each risk factor changed as well. Having a better understanding of these trends might augment our ability to predict this grave obstetric complication and improve maternal outcomes in the future.

Placental abruption: assessing trends in risk factors over time.

PURPOSE: To evaluate changes in the independent contribution of different risk factors for placental abruption over time. METHODS: In this retrospective nested case-control study, trends of change in ORs for known risk factors for placental abruption occurring in three consecutive 8-year intervals were compared. A univariate assessment of factors associated with placental abruption and two multivariable logistic regression models were constructed to identify independent risk factors for placental abruption. Trends of change in the incidence and specific contribution of various risk factors were compared along the study time-period. RESULTS: During the study period, 295,946 pregnancies met the inclusion criteria; of these, 2170 (0.73%) were complicated with placental abruption. Using logistic regression models, previous cesarean delivery, in vitro fertilization (IVF) pregnancy, hypertensive disorders, polyhydramnios, and inadequate prenatal care were recognized as independent risk factors for placental abruption. While the relative contribution of IVF pregnancy and polyhydramnios to the overall risk for abruption decreased over the course of the study, previous cesarean delivery became a stronger contributor for placental abruption. CONCLUSION: In our study, a change over time in the specific contribution of different risk factors for placental abruption has been demonstrated.

Factors Associated With Operatively Confirmed Adnexal Torsion Among Pregnant Women - A Multicenter Cohort Study.

PURPOSE: The aim of this study was to investigate the association of clinical, laboratory, and ultrasound findings with the surgical diagnosis of adnexal torsion in a retrospective cohort of women operated for suspected torsion during pregnancy. MATERIALS AND METHODS: A multicenter retrospective study of pregnant women who underwent urgent laparoscopy for suspected adnexal torsion during 2004-2019 in three tertiary medical centers. RESULTS: Adnexal torsion was found in 143/208 (68.8 %) cases. Women with adnexal torsion had lower parity and lower rates of previous cesarean section, but higher rates of fertility treatments and multiple gestations, and were more likely to report right lower abdominal pain, with shorter duration of symptoms (< 24 hrs) and vomiting but not nausea. Women with adnexal torsion were found to have higher rates of sonographic findings suggestive of ovarian edema, while normal-appearing ovaries on ultrasound were more common in women without torsion. A multivariate logistic regression analysis showed that complaints of right abdominal pain were positively associated with adnexal torsion (aOR [95 % CI] 5.03 (1.45-17.49), while previous cesarean delivery and ultrasound findings of normal-appearing ovaries were negatively associated with adnexal torsion (aOR of 0.17 (0.05-0.52) and 0.10 (0.02-0.43), respectively). CONCLUSION: Clinical characteristics and ultrasound findings may be incorporated into the emergency room workup of pregnant women with suspected adnexal torsion.
