Route of postpartum oxytocin administration and maternal hemoglobin decline - A randomized controlled trial.

OBJECTIVE: Oxytocin uterotonic agents are routinely administered during the third stage of labor, however, the administration route is varying, intravenously or intramuscularly. We aimed to compare the effect of different regimens of postpartum oxytocin administration on hemoglobin (Hb) and hematocrit (Hct) decline. METHODS: A randomized, 3-arm study of women who delivered vaginally at term in a single tertiary medical center was conducted. Immediately following the delivery of the fetus women randomly received one of 3 oxytocin regimens: 1) intramuscular 10units (IM group); 2) intravenous 10units in 100 ml 0.9%NaCl solution over 10-15 min (IV group); or 3) combined IV + IM regimens (IV + IM group). Primary outcome was defined as the level of Hb decline between prepartum and postpartum measurements. RESULTS: Overall, 210 women (70 in each group) were randomized, with 171 included in the final analysis (IM group-61, IV group-57, IV + IM group-53). There was no significant difference between the groups regarding maternal age, pre-pregnancy body-mass-index (BMI), parity, operative vaginal deliveries rate, the rate of episiotomy or perineal tears or neonatal birthweight. Mean prepartum Hb and Hct level were 12.3 ± 1.1 g/dl and 36.9 ± 2.7%, respectively, with no significant difference between the groups. Mean postpartum HB and Hct decline was 1.3 ± 0.8 g/dl and 3.7 ± 2.3%, respectively, with no difference between the groups. In multivariable analysis after adjusting for parity, pre-pregnancy BMI, labor induction, episiotomy or perineal tears and neonatal birthweight, oxytocin regimen was not associated with any difference in hematological measurements. CONCLUSION: Postpartum Hb and Hct decline was usually minor following vaginal deliveries, and was not affected by postpartum oxytocin regimen.

Risk factors for postpartum hemorrhage following cesarean delivery.

OBJECTIVE: To identify risk factors for postpartum hemorrhage (PPH) following cesarean delivery (CD). METHODS: A retrospective study of all women who underwent CD in a university-affiliated tertiary hospital (2014-15). PPH was defined as any of the following: clinical PPH (≥1000 ml estimated blood loss), hemoglobin (Hb) drop ≥3 g/dl (the difference between pre-CD Hb level within a 24 h prior to the delivery) and post-CD (nadir level during the first 72 h after CD)) or the need for blood products transfusion. The characteristics of women with PPH following CD were compared to a control group of those with CD without PPH. RESULTS: Of the 15,564 deliveries during the study period, 3208 (20.6%) women met inclusion criteria, of them, 307 (9.6%) had PPH and 2901 (90.4%) served as controls. Women in the PPH group were younger (32.6 ± 5.3 vs. 33.5 ± 5.4, p = .006) and more often nulliparous (45.9% vs. 33.3%, p<.001) compared to the controls. However, there were no differences between the groups regarding the rate of multiple gestations, maternal diabetes mellitus, hypertensive disorders, polyhydramnios, and macrosomia. The rates of induction of labor (16.3% vs. 8.6%, p<.001) and urgent CD (47.9% vs. 32.0%, p<.001) were higher in the PPH group compared to the controls. In multivariate logistic regression, predictors for PPH following CD were (odds ratio, 95% confidence interval) urgent CS (1.57, 1.78-2.11, p = .002), CD duration (1.02, 1.01-1.03, p<.001), and the number of previous CDs (0.74, 0.62-0.90, p = .003). CONCLUSIONS: In women undergoing cesarean section, urgent CD, the duration of the surgery, and the number of the previous CD are associated with the risk of PPH and should be taken into consideration during the postpartum assessment.

Questionnaire-based vs universal PCR testing for SARS-CoV-2 in women admitted for delivery.

BACKGROUND: It has been suggested that women admitted for delivery should have universal PCR testing for SARS-CoV-2. Yet, the considerable difference in the incidence of COVID-19 between different geographic regions may affect screening strategies. Therefore, we aimed to compare questionnaire-based testing versus universal PCR testing for SARS-CoV-2 in women admitted for delivery. METHODS: A prospective cohort study of women admitted for delivery at a single center during a four-week period (April 22-May 25, 2020). All women completed a questionnaire about COVID-19 signs, symptoms, or risk factors, and a nasopharyngeal swab for PCR for SARS-CoV-2. Women who were flagged as suspected COVID-19 by the questionnaire (questionnaire-positive) were compared with women who were not flagged by the questionnaire (questionnaire-negative). RESULTS: Overall, 446 women were eligible for analysis, of which 54 (12.1%) were questionnaire-positive. PCR swab detected SARS-CoV-2 in four (0.9%) women: 3 of 392 (0.8%) in the questionnaire-negative group, and 1 of 54 (1.9%) in the questionnaire-positive group (P = .43), yielding a number needed to screen of 92 (95% CI 62-177). In 96% of the cases, the PCR results were obtained only in the postpartum period. No positive PCR results were obtained from neonatal testing for SARS-CoV-2. The sensitivity of the questionnaire was 75.0%, and the negative predictive value was 99.7%. CONCLUSIONS: Although the rate of positive PCR results was not significantly different between the groups, the number needed to screen is considerably high. The use of questionnaire-based PCR testing in areas with low incidence of COVID-19 allows for a reasonable allocation of resources and is easy to implement.

The association between adipocytokines and glycemic control in women with gestational diabetes mellitus.

Objective: To evaluate the relationship between adipocytokines and glycemic control.Study design: Prospective observational trial of gestations with gestational diabetes mellitus (GDM). Fasting glucose (FG), insulin, adiponectin, leptin, chemerin, retinol-binding protein 4 (RBP-4), osteocalcin, and resistin were measured. HomeOstasis model assessment of insulin resistance (HOMA-IR) and QUantitative insulin sensitivity ChecK Index (QUICKI) were calculated. Women who required medications for glycemic control were compared to women using nutritional therapy only.Results: Overall, 75 women were included -26 (34.7%) required medications to achieve good glycemic control. Factors associated with poor control are as follows: low resistin (aOR 0.84), HOMA-IR (aOR 1.96), QUICKI (aOR 0.62), first trimester FG (aOR 1.43), and maternal age (aOR 1.26). HOMA-IR and QUICKI performed highest for prediction. Resistin, first trimester FG, maternal age, and QUICKI had an AUC of 0.878, sensitivity and specificity of 87.5% for the prediction of the need for medications.Conclusions: Low resistin is associated with poor control. A model utilizing maternal age, first trimester fasting glucose, and first visit QUICKI yields good predictability.

Second Trimester Biochemical Markers as Possible Predictors of Pathological Placentation: A Retrospective Case-Control Study.

OBJECTIVE: We aimed to evaluate the association between second trimester biochemical markers and pathological placentation. METHODS: This was a retrospective case-control study (2007-2014) of singleton gestations at a university-affiliated tertiary center. Women with pathologic placentation were subdivided into three groups: placenta accreta (group A), placenta previa (group B), or both (group C). We compared second trimester biochemical screening markers taken between 16 + 0 and 19 + 6 weeks of gestation between groups A, B, and C, and women with normal placentation (group D). Obstetrical and neonatal outcomes, risk factors for pathologic placentation, and second trimester biochemical marker values were compared between groups. RESULTS: Overall, 301 deliveries were evaluated: 64 (21%) in group A, 66 (22%) in group B, 17 (6%) in group C, and 153 (51%) in group D. Each of the pathological placentation groups individually had a higher median alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG) multiples of median (MoM) than the controls, with the highest values of AFP and hCG observed among women with placenta accreta and the lowest values among the controls. When a multivariant analysis was applied, the hCG levels remained significantly correlated with pathological placentation. Receiver operation characteristic curves for AFP, hCG, or both were computed. For AFP the area under the ROC curve (AUC) was 0.573 (95% CI 0.515-0.630, p < 0.0274) and a cut-off value above 0.99 MoM demonstrated a sensitivity and specificity of 71 and 46%, respectively, for the prediction of pathological placentation. For hCG, the AUC was 0.662 (95% CI 0.605-0.715, p < 0.0001) and a cut-off value of 1.25 MoM demonstrated a sensitivity and specificity of 53 and 68%. When both markers were plotted, the AUC was 0.668 (95% CI 0.611-0.721, p < 0.0001) and sensitivity and specificity were 63 and 64%, respectively. A percentile MoM cut-off approach distinguished between two groups: a high-risk group (patients with AFP or hCG or both above the 75th percentile, odds ratio (OR) for pathological placentation 2.27, 95% CI 1.42-3.63), and a low-risk group (patients with AFP or hCG or both below the 25th percentile, OR for pathological placentation 0.38, 95% CI 0.24-0.60). CONCLUSION: Second trimester biomarkers such as hCG and AFP can be used to raise a suspicion towards characterizing women into high-risk and low-risk groups for pathological placentation.

Outcome of vaginal mesh reconstructive surgery in multiparous compared with grand multiparous women: Retrospective long-term follow-up.

We aimed to compare the long-term surgical outcome and complications of multiparous and grand multiparous women undergoing reconstructive surgery with vaginal mesh implants for repair of pelvic organ prolapse. This retrospective, long-term follow-up (28.17±20.7 months) comprised 113 women who underwent surgical reconstructive surgery with vaginal polypropylene mesh in a high parity rate population medical center. The women were divided into 2 groups (multiparous and grand multiparous) and each group was evaluated for objective and subjective surgical outcome. Patient demographics and surgical data were retrieved from electronic medical records. Outcome measure included POP-Q exam as objective outcome and validated Pelvic Floor Distress Inventory questionnaire (PFDI) to assess subjective outcome. Average age of patients was 62±7.9 (range 42-83) years. Average parity was 5.6±3.1 (range 1-14). There were 54 (47.7%) multiparous women and 59 (52.3%) grand multiparous women. The grand multiparous women were younger than the multiparous women and had a significantly higher degree of prolapse. At the last follow-up, the only significant difference was related to symptoms of an overactive bladder. In conclusion, long-term follow-up demonstrates that vaginal mesh surgery in grand multiparous women offers anatomical and subjective cure rates comparable to multiparous women.

Risk factors for post-partum hemorrhage following vacuum assisted vaginal delivery.

OBJECTIVE: To identify risk factors for post-partum hemorrhage (PPH) following vacuum assisted vaginal delivery (VAVD). STUDY DESIGN: A retrospective study of all women with singleton pregnancies who underwent VAVD in a tertiary hospital (2012-2014). PPH was defined as any of the following: ≥500 ml estimated blood loss, hemoglobin drop ≥3 g/dl (difference between pre- and post-VAVD hemoglobin levels) or the need for blood products transfusion. Characteristics of women with PPH following VAVD were compared to those of women with no PPH following VAVD. RESULTS: Of 1,154 VAVDs, 295 (25.6 %) had PPH. Women in the PPH group were more often nulliparous (83.1 vs. 70.5 %, p = 0.001) and had higher rate of hypertensive disorders (4.4 vs. 1.4 %, p = 0.001). The rate of episiotomy (87.8 vs. 81.6 %, p = 0.01) was higher in the PPH group. In multivariate analysis, risk factors for PPH were (Odds Ratio, 95 % Confidence Interval) hypertensive disorders (2.40, 1.03-5.58, p = 0.04), induction of labor (1.42, 1.01-2.10, p = 0.04) and longer second (1.003, 1.001-1.006, p = 0.03) and 3rd (1.02, 1.01-1.04, p = 0.004) stages of labor. CONCLUSION: Risk factors for PPH following VAVD can be identified and should be taken into consideration at the immediate post-partum period.

Risk Factors for Unintended Dural Puncture in Obstetric Patients: A Retrospective Cohort Study.

BACKGROUND: Unintended dural puncture (UDP) is one of the main risks of epidural analgesia, with a reported incidence of approximately 1.5% among the obstetric population. UDP is associated with maternal adverse outcomes, with the most frequent adverse outcome being postdural puncture headache (PDPH). Our retrospective cohort study objective was to identify demographic and obstetric risk factors that increase the risk of unintentional dural puncture as well as describing the obstetric outcome once a dural puncture has occurred. METHODS: We retrospectively reviewed all cases of UDPs during attempted vaginal delivery between the years 2004 and 2013 in a single Israeli hospital. Each UDP case was matched with the 2 parturients who received epidural analgesia before and 2 parturients after performed by the same anesthesiologist (control group). Demographic, anesthetic, and obstetric variables were compared between the UDP and control groups. RESULTS: Out of 46,668 epidural procedures, 177 cases of UDPs were documented (0.4%). One hundred seven women (60.5%) developed PDPH, and 38 (35.5%) required an epidural blood patch. In multivariate logistic regression, the degree of cervical dilation in centimeters at the time of epidural insertion was associated with an increased rate of UDP (P < .001). Multiparity was associated with PDPH after UDP (P = .004). Women with UDP had longer length of hospital stay than those without UDP (P < .001). CONCLUSIONS: UDP, an uncommon complication, is associated with obstetric factors. Nevertheless, it does not seem to be associated with adverse obstetric outcomes except for prolonged duration of hospital stay.

Maternal hemoglobin decline following 'uneventful' cesarean delivery.

OBJECTIVE: To assess hemoglobin (Hb) decline following elective and non-elective uneventful cesarean section (CS). METHODS: A retrospective cohort study of all women with singleton pregnancy who underwent uneventful CS defined as clinical estimation of intra-operative bleeding < 1000 ml. Hemoglobin decline (pre- and post-CS levels difference) of women with non-elective CS (during labor/delivery process) were compared to those who underwent elective CS (no labor). Cases complicated by placenta previa/abruption were excluded. RESULTS: Overall 2767 women underwent uneventful CS, of them, 954 (34.5%) were non-elective and 1813 (65.5%) were elective. Hemoglobin decline was higher in the non-elective group (1.5 ± 1.3 versus 1.0 ± 1.2 g/dL, p < 0.001). This was also observed in the nulliparous patients as well as in those with previous single CS subgroups. The rate of Hb decline ≥3 g/dL and the rate of post-CS Hb < 7 g/dL were higher in the non-elective group (8.9% versus 3.1%, p < 0.001 and 2.3% versus 0.4%, p = 0.001, respectively). On multivariable analysis, non-elective CS was found to be significantly associated with Hb decline of ≥3 g/dl after surgery (aOR = 2.10, 95% CI 1.36-3.23, p = 0.001) and need for blood products transfusion (aOR = 2.24, 95% CI 1.04-4.83, p = 0.03). CONCLUSION: Non-elective CS was associated with an increased risk of Hb decline and blood product transfusion even in an apparent uneventful operation.

Factors Affecting Adnexal Torsion Direction: A Retrospective Cohort Study.

AIMS: To investigate a trend for adnexal torsion direction and factors that may be associated with direction. METHODS: We retrospectively reviewed the medical files of all women who underwent exploratory laparoscopy for suspected ovarian torsion in our center from August 2010 to December 2012. RESULTS: Fifty-five women had laparoscopically proven torsion. Medial rotation, defined as clockwise rotation of the left adnexa or counterclockwise rotation of the right adnexa, with the proximal (lateral) segment of the infundibulopelvic ligament serving as the referral point was noted in most cases (n = 47, 85.5%). There was no statistically significant difference between the medial and lateral rotation groups. However, the proportion of pregnant women and mean parity were significantly higher in the lateral compared to the medial rotation group: 62.5 vs. 19.1%, p = 0.009 and 1.1 ± 1.2 vs. 0.1 ± 0.4, p < 0.001. Medial torsion was present in 64.3% of pregnant women vs. 92.7% of nonpregnant women, p = 0.009. CONCLUSION: The direction of ovarian or adnexal torsion is usually medially rotated, opposite to the psoas muscles and the great blood vessels on the same side. However, surgeons should be aware of an increased rate of lateral rotation among pregnant women.

Anatomical diversity of the female external genitalia and its association to sexual function.

OBJECTIVE: To provide data on the anatomical dimensions of adult female genitalia and to investigate the possible association of vulvar morphology and sexual function. STUDY DESIGN: This cross-sectional prospective cohort study, using measurements of the external genitalia was performed in a day-care unit of a tertiary, university-affiliated medical center from 2013 to 2014. Thirty-two premenopausal women aged 20-51 years, undergoing gynecological procedures under general anesthesia (not involving the external genitalia) were asked to respond to both a local general data questionnaire and a validated sexual function questionnaire (PISQ-12). Based on reported orgasmic performance during sexual intercourse, patients were divided into two groups, and the measured genital features were compared. RESULTS: Age, body mass index, parity and sexual activity history were recorded. A wide range of values was noted for each measurement. There was no statistically significant association between external genitalia measurements and age, parity or sexual activity. There was no statistically significant difference in any of the external genitalia measurements between the groups. CONCLUSION: Wide variability exists in the appearance of female external genitalia. Sexual function does not appear to be associated with genital dimensions. This information is important for both women and surgeons when considering cosmetic vulvar surgery.

Colpocleisis surgery in women over 80 years old with severe triple compartment pelvic organ prolapse.

OBJECTIVE: To compare outcomes of Le Fort colpocleisis surgery, between women over 80 years old and younger women. STUDY DESIGN: We searched the medical files for all consecutive women who underwent Le Fort colpocleisis as a primary or recurrent surgery for severe pelvic organ prolapse at our university-affiliated tertiary center between February 2007 and July 2013. Exclusion criteria for performance of the procedure were post-menopausal bleeding, pelvic malignancy, pelvic irradiation, and the desire to preserve coital function. The objective and subjective recurrence of prolapse, intraoperative and postoperative complications, and patient satisfaction were measured. RESULTS: Forty-seven women underwent Le Fort colpocleisis. Of them, 23 were above 80 years, mean age 84.0±3.3, oldest: 91; and 24 were 80 years old and younger, mean age 70.8±6.1, youngest: 61. There were no intraoperative complications. Postoperative complications were recorded for 2 women with lower urinary tract infection and one woman had longer hospitalization time for warfarin treatment adjustment (9 days). Objective cure rates were 82.7% (19/23) and 83.3% (20/24), p=0.32, for women over 80, and women aged 80 and younger, respectively. The subjective cure rate was 86.7% (20/23) and 91.6% (22/24), respectively, p=0.28. CONCLUSIONS: Objective and subjective cure rates of Le Fort colpocleisis in women over age 80 years were similar to those for younger women. The complications were mild and few, and unrelated to age. This procedure may be offered for women over 80 years old with severe symptomatic pelvic organ prolapse and medical comorbidities.

Endometrial Cancer Surgery for Elderly Women--The Early Postoperative Period.

OBJECTIVE: The aim of this study was to examine the early postoperative period and assess whether elderly patients recuperate differently than do their younger counterparts after surgery for endometrial cancer. METHODS: This retrospective chart review comprised all women older than 75 years who underwent laparotomy for endometrial cancer staging at our center from January 2005 through December 2010 and a consecutive control group of women younger than 74 years. Parameters included demographic variables, surgical procedure/findings, postoperative morbidity, and pathology. RESULTS: Ninety patients older than 75 years and 88 younger patients were identified. The elderly patients had a statistically significant prolonged wait for bowel movement (5.9 vs 3.1 days, P = 0.002) and ambulated later (4.1 vs 1.1 days, P < 0.001). Postoperative hospital stay was similar in both groups (5.8 vs 4.2 days, P = 0.37). Early postoperative complications (fever, bowel, wound, eventration, cardiopulmonary) occurred at a similar rate in both groups. CONCLUSIONS: Elderly patients after laparotomy for endometrial cancer staging ambulated later and recovered bowel function later than did the younger patients. This did not translate into prolonged hospital stay or excessive complications. Earlier intervention with physical therapy and stool softeners can possibly close this gap in recovery.

Uterine papillary serous carcinoma pre-operatively diagnosed as endometrioid carcinoma: Is omentectomy necessary?

BACKGROUND: Uterine papillary serous carcinoma (UPSC) is a relatively rare but aggressive uterine malignancy comprising approximately 10% of endometrial cancers. Many women pre-operatively misdiagnosed as having endometrioid carcinoma have ultimately UPSC on final pathology. These women receive inadequate surgical staging without omentectomy. AIM: To assess the value of omentectomy on disease-free interval and overall survival in women with UPSC who had an initial diagnosis of endometrioid carcinoma. METHODS: This retrospective study included all women treated for the final diagnosis of UPSC in our centre from January 2007 to December 2012. Data regarding patient demographics, staging procedures, histology results, adjuvant therapy and follow-up outcomes were recorded. RESULTS: Of the 52 women with a final diagnosis of UPSC, more than 45% had an initial diagnosis of endometrioid carcinoma. All women underwent hysterectomy and removal of the adnexa. Lymph node evaluation was performed in 75% of women. Omentectomy was performed in 30/52 women (58%). Of those, three women (10%) had omental involvement. Mean disease-free interval with omentectomy was 24.5 months versus 30.5 months without (P = 0.29). Mean overall survival was 33 months with an omentectomy and 29 months without (P = 0.32). Recurrence patterns did not differ between groups. CONCLUSION: Women diagnosed pre-operatively with endometrioid carcinoma and eventually found to have UPSC can expect no change in prognosis despite not having undertaken a full staging procedure. Repeat surgery for omentectomy is probably of no benefit.

The significance of paracardiac lymph-node enlargement in patients with newly diagnosed stage IIIC ovarian cancer.

OBJECTIVE: Extra-abdominal metastases in epithelial ovarian cancer (EOC) are relatively rare. Interpreting computed tomography (CT) scans, during initial work-up, little attention is focused on enlargement of paracardiac lymph nodes (PCLN) and their significance is not clear. We aimed to examine whether the presence of PCLN during initial diagnosis of EOC influences prognosis. METHODS: A retrospective study comparing patients with stage 3 EOC who were diagnosed with PCLN on CT scan during initial evaluation to stage 3C patients without PCLN. Scans were reviewed by a single radiologist for peritoneal involvement, distal metastases and presence of PCLN. Disease status at diagnosis, results of surgery, chemotherapy and response, disease-free interval (DFI) and overall survival (OS) were recorded. RESULTS: Thirty one patients with stage 3C EOC with PCLN on initial CT scan were included and compared with 41 controls. There was no significant difference between groups in abdominal optimal cytoreduction rate. Lower rates of complete response (CR) to initial treatment were detected in the study group (45.2% vs. 78.0%, p=.004). In survival analysis, the DFI for patients with PCLN was shorter (median 9.0 vs. 24.0 months, p=.0097) and overall survival was shorter (median 31.7 vs. 61.3 months, p=.001). Multivariate analysis showed that PCLN was significantly associated with a lower rate of CR, a shorter DFI and a shorter OS. CONCLUSION: The presence of enlarged PCLN at presentation appears to be associated with poor prognosis in stage 3C EOC. Further attention should be given to detection and follow-up of such findings when considering treatment.

Uterine electric activity during the third stage of labor; a look into the physiology of a deserted stage.

OBJECTIVE: To evaluate uterine activity during the third stage of labor and compare it to that observed in the second stage of labor. STUDY DESIGN: Uterine electric activity was prospectively measured using electrical uterine myography (EUM) in 44 women with singleton pregnancy at term during the final 30 min of the second stage and throughout the third stage of labor. Results are reported using a scoring index of 1-5 mWS (micro-Watt-Second). Patients were stratified into two groups based on the duration of the third stage (<15 min and >=15 min) RESULTS: The mean durations of the second and third stages were 51.9 ± 63.5 and 15.4 ± 7.5 minutes, respectively. During the third stage, uterine activity (contractions peaks) was similar to that observed during the second stage of labor (3.43 ± 0.64 mWS versus 3.42 ± 0.57 mWS, p = 0.8). No correlation was found between the duration of the third stage and EUM measurements during the third (p = 0.9) or the second (p = 0.2) stages of labor. No association was found between EUM measurements during the third stage and parity, maternal age, fetal weight, duration of labor, gestational age, gravity or BMI. The rate of oxytocin use during the second stage and EUM measurements during the second or third stage did not differ among women with short versus long duration of the third stage. CONCLUSION: Uterine activity during the third stage is comparable and as intense as that occurring during the second stage. Third stage length cannot be predicted by contraction intensity during the second or third stage of labor.

[Predicting pregnancy outcomes based on first trimester screening].

Pregnancy surveillance in the western world focuses on the second and third trimesters. Recently, a few studies demonstrated that several pregnancy outcomes can be predicated by first trimester screening, especially in the time period between 11 + 0 to 13 + 6 weeks of gestation. These outcomes include the risk of developing preeclampsia, small for gestational age (SGA) and macrosomic fetuses, risk of abortion or intrauterine fetal death, risk of preterm labor and the risk of developing gestational diabetes. This review focuses on these findings and examines if it is feasible to expand the nuchal translucency and first trimester biochemical screening that is customary in Israel, so it may include additional parameters to predict those pregnancy outcomes.
