A new care pathway to optimize gestational weight gain in twin pregnancies.

BACKGROUND: Maternal gestational weight gain is an important determinant of pregnancy outcomes and may have an even greater role in twin pregnancies because of their higher rate of pregnancy complications and greater nutritional demands. However, data on the optimal week-specific gestational weight gain in twin pregnancies and on interventions that should be applied in cases of inadequate gestational weight gain are limited. OBJECTIVE: This study aimed to determine whether a new care pathway that involves monitoring gestational weight gain using a week-specific chart, along with a standardized protocol for managing cases with inadequate gestational weight gain, can optimize maternal gestational weight gain in twin pregnancies. METHODS: In this study, patients with twin pregnancies followed in a single tertiary center between February 2021 and May 2022 were exposed to the new care pathway (postintervention group). Gestational weight gain and clinical outcomes were compared with those of a previously described cohort of patients with twins followed in our clinic before the implementation of the new care pathway (preintervention group). The new care pathway targeted patients and care providers and included educational material, a newly developed body mass index group-specific gestational weight gain chart, and a stepwise management algorithm in cases of inadequate gestational weight gain. The body mass index group-specific gestational weight gain charts were divided into 3 zones: (1) green zone (optimal gestational weight gain at 25th-75th centiles); (2) yellow zone (suboptimal gestational weight gain at 5th-24th or 76th-95th centiles); and (3) gray zone (abnormal gestational weight gain, at <5th or >95th centile). The primary outcome was the overall proportion of patients achieving optimal gestational weight gain at birth. RESULTS: A total of 123 patients were exposed to the new care pathway and were compared with 1079 patients from the preintervention period. Patients in the postintervention group were more likely to achieve optimal gestational weight gain at birth (60.2% vs 47.7%; adjusted odds ratio, 1.91; 95% confidence interval, 1.28-2.86) and were less likely to achieve low-suboptimal gestational weight gain (7.3% vs 14.7%; adjusted odds ratio, 0.41; 95% confidence interval, 0.20-0.85) or any suboptimal gestational weight gain (26.8% vs 34.8%; adjusted odds ratio, 0.60; 95% confidence interval, 0.39-0.93) at birth. In addition, patients in the postintervention group were less likely to have low-abnormal gestational weight gain anytime during gestation (18.9% vs 29.1%; P=.017) and were more likely to have normal gestational weight gain throughout pregnancy (21.3% vs 14.0%; P=.031) or high-abnormal gestational weight gain anytime during gestation (18.0% vs 11.1%; P=.025), suggesting that in comparison with standard care, the new care pathway is more effective in preventing patients from moving into the low-abnormal zone than the high-abnormal zone. Furthermore, the new care pathway was more effective than standard care in correcting high-suboptimal gestational weight gain and high-abnormal gestational weight gain. CONCLUSION: Our findings suggest that the new care pathway may be effective in optimizing maternal gestational weight gain in twin gestations, which may in turn contribute to better clinical outcomes. This is a simple, low-cost intervention that can be easily disseminated among providers caring for patients with twin pregnancies.

Delays to Surgery in Emergency Department Cases of Ectopic Pregnancy: A Quality Improvement Study.

OBJECTIVE: Create a process map for emergency department (ED) presentations of surgical ectopic pregnancy, and identify areas of management amenable to quality improvement. METHODS: A retrospective chart review of all patients undergoing surgical management of ectopic pregnancy at a large, urban, academic tertiary care centre from 2015 to 2017 was performed. RESULTS: Seventy-three patients were included. There were 6 (8.2%) unstable A cases (recommended time to operating room [OR] 0-2 hours), 23 (31.5%) stable A cases, and 44 (60%) B cases (recommended time to OR 2-8 hours). The percent of patients who were in the OR within the recommended time window were 6 (100%) for unstable A cases, 13 (56%) stable A cases, and 29 (65.9%) stable B cases, respectively (P = 0.139). Notable time delays include the time from gynaecology referral to the time seen by gynaecology (29.7% of total wait time for stable A cases from ED to OR) and the time the OR was booked to the time the patient was brought to the OR (53.2% of total wait time for stable B cases). Of the patients seen by physician at the emergency department first, the time from triage to the OR was significantly shorter for patients that received bedside ultrasound only (0.67 ± 0.5 hours vs. 2.1 ± 1.8 hours [P = 0.007]). CONCLUSION: This is the first study to map the ED presentation of surgical ectopic pregnancy. The management of ectopic pregnancy would benefit from the development of surgical triage decision aids, a surgical care pathway, and increased use of screening bedside ultrasound.

Impact of Minimally Invasive Gynaecology Fellowship Training on Quality Performance Metrics for Hysterectomy.

OBJECTIVE: To evaluate differences in quality metrics between hysterectomies performed by fellowship-trained surgeons and those performed by generalists. METHODS: Retrospective review of 2845 consecutive hysterectomies by 75 surgeons (23 fellowship-trained, 52 generalists) at 7 hospitals in Ontario, Canada. The primary outcome was a composite of any complication or return to the emergency department (ED) within 30 days of hysterectomy. Secondary outcomes were 2 quality outcome measures (grade of complication and return to ED within 30 days) and 4 quality process measures (minimally invasive hysterectomy rate, rate of preoperative anemia, same-day discharge for laparoscopic hysterectomy [LH], and performing cystoscopy at LH). RESULTS: Fellowship-trained surgeons were more likely to perform concurrent resection of endometriosis, bilateral ureterolysis, lysis of adhesions, uterine/internal iliac artery ligation, and morcellation (all P < 0.001). Generalists performed more vaginal procedures, including vaginal repair, vault suspension, and insertion of mid-urethral sling (all P < 0.001). After controlling for patient and surgical factors, there was no difference in the primary outcome (adjusted odds ratio [aOR] 1.07; 95% CI 0.79-1.45, P = 0.667). Fellowship-trained surgeons were more likely to perform minimally invasive hysterectomy (aOR 2.38; 95% CI 1.15-4.93, P = 0.020), had higher rates of same-day discharge for LH (aOR 2.23; 95% CI 1.31-3.81, P = 0.003), and were more likely to perform cystoscopy (unadjusted OR 2.94; 95% CI 2.30-3.85, P < 0.001). There were no differences in the rates of preoperative anemia, surgical complications, and ED visits. CONCLUSION: Differences exist between fellowship-trained surgeons and generalists regarding case mix and process quality metrics. Postoperative complications and readmissions were comparable for both groups of surgeons.

Ruptured Degenerating Fibroid Causing Preterm Labour and Systemic Inflammatory Response Syndrome.

BACKGROUND: Fibroids are present in at least 10% of pregnancies and are recognized to cause a variety of complications. A few case reports have described fibroids as an etiological factor in uterine rupture, sometimes with life-threatening hemorrhage. CASE: A 28-year-old G1, P0 woman at 20 weeks gestation developed systemic inflammatory response syndrome with acute renal failure and massive ascites secondary to a ruptured degenerated fibroid. This resulted in preterm delivery and neonatal death. At 6 weeks postpartum, she successfully underwent an abdominal myomectomy. CONCLUSION: This is a rare case of uterine fibroid rupture causing preterm labour and systemic inflammatory response syndrome. This report discusses the diagnosis of uterine rupture related to the fibroid with imaging and subsequent management, which included fertility-preserving surgery.

Preoperative Practice Paired With Instructor Feedback May Not Improve Obstetrics-Gynecology Residents' Operative Performance.

BACKGROUND: There is evidence that preoperative practice prior to surgery can improve trainee performance, but the optimal approach has not been studied. OBJECTIVE: We sought to determine if preoperative practice by surgical trainees paired with instructor feedback improved surgical technique, compared to preoperative practice or feedback alone. METHODS: We conducted a randomized controlled trial of obstetrics-gynecology trainees, stratified on a simulator-assessed surgical skill. Participants were randomized to preoperative practice on a simulator with instructor feedback (PPF), preoperative practice alone (PP), or feedback alone (F). Trainees then completed a laparoscopic salpingectomy, and the operative performance was evaluated using an assessment tool. RESULTS: A total of 18 residents were randomized and completed the study, 6 in each arm. The mean baseline score on the simulator was comparable in each group (67% for PPF, 68% for PP, and 70% for F). While the median score on the assessment tool for laparoscopic salpingectomy in the PPF group was the highest, there was no statistically significant difference in assessment scores for the PPF group (32.75; range, 15-36) compared to the PP group (14.5; range, 10-34) and the F group (21.25; range, 10.5-32). The interrater correlation between the video reviewers was 0.87 (95% confidence interval 0.70-0.95) using the intraclass correlation coefficient. CONCLUSIONS: This study suggests that a surgical preoperative practice with instructor feedback may not improve operative technique compared to either preoperative practice or feedback alone.

The Unintended Consequences of an FDA Warning: The Case of Power Morcellation in Myoma Surgery.

OBJECTIVE: To study patients' perspectives regarding the risks and benefits of the use of power morcellation. DESIGN: Cross-sectional survey (Canadian Task Force classification II-3). SETTING: Academic tertiary referral hospital. PATIENTS: Women waiting in gynecology waiting rooms. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: Of the 321 women invited, 310 (97%) responded to the survey; 19% of the participants had myomas requiring treatment, and the other 81% did not. Women with myomas were more likely to be aware of the risks of morcellation (32% vs 14%; p < .001); 29% obtained their information directly from their physicians, while 71% obtained it from other resources. After reading about the risks and benefits of open and MIS approaches to myoma removal, 65% would choose an MIS approach if the risk of cancer spread was up to 0.3% (1 in 350). The majority of women (75%) felt that the government should not have a role in surgical decision making, but should provide information to help patients make decisions. CONCLUSION: Women have different risk tolerances. Most women would be willing to take the 1 in 350 (0.3%) risk of undiagnosed sarcoma spread to benefit from MIS approaches. FDA warnings may have unintended consequences by limiting the acceptable medical choices available for patients.

Concealed postpartum hemorrhage treated with transcatheter arterial embolization.

BACKGROUND: Postpartum hemorrhage is an obstetric emergency and is a major preventable cause of maternal morbidity and mortality. An arteriovenous fistula is a rare cause of concealed postpartum hemorrhage. CASE: A 20-year-old woman spontaneously delivered at 40 0/7 weeks of gestation. Twelve hours after delivery, she became hemodynamically unstable, developing a large left vaginal hematoma. An angiogram revealed extravasation originating from the right pudendal artery with early filling of a draining vein, consistent with a traumatic arteriovenous fistula. Complete occlusion of the fistula was achieved by embolizing a branch of the right pudendal artery. The postprocedure course was uneventful. CONCLUSION: A vaginal arteriovenous fistula should be considered in cases of concealed postpartum hemorrhage; transcatheter arterial embolization is an effective treatment for these cases.

c-Rel phenocopies PKCtheta but not Bcl-10 in regulating CD8+ T-cell activation versus tolerance.

Elucidating the signaling events that promote T-cell tolerance versus activation provides important insights for manipulating immunity in vivo. Previous studies have suggested that the absence of PKCtheta results in the induction of anergy and that the balance between the induction of the transcription factors NFAT, AP1 and NF-kappaB plays a key role in determining whether T-cell anergy or activation is induced. Here, we examine whether Bcl-10 and specific family members of NF-kappaB act downstream of PKCtheta to alter CD8(+) T-cell activation and/or anergy. We showed that T cells from mice deficient in c-Rel but not NF-kappaB1 (p50) have increased susceptibility to the induction of anergy, similar to T cells from PKCtheta-deficient mice. Surprisingly T cells from Bcl-10-deficient mice showed a strikingly different phenotype to the PKCtheta-deficient T cells, with a severe block in TCR-mediated activation. Furthermore, we have also shown that survival signals downstream of NF-kappaB, are uncoupled from signals that mediate T-cell anergy. These results suggest that c-Rel plays a critical role downstream of PKCtheta in controlling CD8(+) T-cell anergy induction.
