Adverse Perinatal Outcomes

Abstract Background Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. Methods We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. Results Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. Conclusion There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.

Abstract BackgroundThere are many reports staged bilateral THA without drainage is a better method than with drainage in many ways. However, there is little report regarding bilateral simultaneous THA (BSTHA) without drainage. This study aimed to evaluate the differences in the clinical outcomes and complication rate of BSTHA with drainage and without drainage.MethodsBetween October 2015 and April 2019, a retrospective cohort study was conducted with modified minimally invasive two-incision method and a consecutive series of 41 BSTHA performed with drainage were compared to 37 BSTHA performed without drainage. It was assessed clinically and radiographically for a mean of 2.1 ± 0.8 years (range, 1.0-4.8 years). Postoperative hematologic values (Hgb drop, Hct drop, total blood loss, transfusion rate), pain susceptibility, functional outcome, and complication were compared in the drained group and the non-drained group. All patients preoperatively received intravenous tranexamic acid (TXA) and intraoperatively received intra-articular TXA on each hip. Statistical analyses were performed using the independent t tests, Chi-squared or Fisher’s exact tests. A significance level of ≤ 0.05 was used for all statistical tests.Results Mean postoperative Hgb (g/dL, p < 0.001) & Hct drop (%, p < 0.001), mean total blood loss (ml, p < 0.001) and mean transfusion unit (IU, p < 0.001) were significantly lower in the BSTHA without drainage than in the BSTHA with drainage group. But the mean dose of morphine equivalent (mg, p < 0.001) was significantly larger in BSTHA without drainage.ConclusionBSTHA without drainage can reduce postoperative blood loss and the requirement for transfusion without increasing other complication. But BSTHA without drainage is more painful method than BSTHA with drainage. Therefore, BSTHA without drainage will be a good option to reduce the burden on the patient by reducing postoperative bleeding if it can control pain well after surgery.

Abstract Background: Diverticulum, one of the long-term squelae of cesarean section, can cause abnormal uterine bleeding, dysmenorrhea and chronic pelvic pain. Hysteroscopic resection of diverticula is thought to reduce abnormal uterine bleeding and chronic pelvic pain. In this study, we aim to describe the improvement after hysteroscopic resection of cesarean section diverticula hysteroscopic resection of cesarean section diverticula (CSD) in women without childbearing intention, and to explore the variables associated with poor prognosis.Methods: A retrospective cohort study of women aged 25-48 with CSD diagnosis by transvaginal ultrasonography (TVS) and hysteroscopy that were enrolled at Guangzhou Women and Children’s Medical Center between June 2017 and December 2018. A total of 124 women met the inclusion criteria and all patients had undergone hysteroscopic resection and accepted a follow-up interview at the 3rd and 6th months postoperatively to record symptom improvement.Result: The mean of intraoperative blood loss and operative time of hysteroscopic resection were (12.94±12.63) ml and (33.63±6.87) min in 124 patients. Overall observed improvement rates of CSD symptom were 47.2% and 65.6% in the first 3 and 6 months, respectively. Multivariable logistic regression models revealed that timing of surgery <14 days was a good prognostic factor associated with both 3-month improvement (OR, 16.59; 95% CI, 2.62-104.90; P=0.003) and 6-month improvement (OR, 15.51; 95%CI, 1.63-148.00; P=0.02); Patients with numbers of cesarean section(CS) ≥2 had a lower rate of improvement after 6 months of CSD repair surgery compared with patients who underwent one CS(OR, 8.29; 95%CI, 1.05-65.75; P=0.04).Conclusions: A hysteroscopic repair might be an appropriate method for CSD in women who no childbearing intentions. The timing of surgery and the number of CS seems to be factors influencing the postoperative improvement of CSD.
