Objectives: Cocaine is the second most frequently used illicit drug worldwide (after cannabis), and cocaine use disorder (CUD)-related deaths increased globally by 80% from 1990 to 2013. There is yet to be a regulatory-approved treatment. Emerging preclinical evidence indicates that deep brain stimulation (DBS) of the nucleus accumbens may be a therapeutic option. Prior to expanding the costly investigation of DBS for treatment of CUD, it is important to ensure societal cost-effectiveness., Aims: We conducted a threshold and cost-effectiveness analysis to determine the success rate at which DBS would be equivalent to contingency management (CM), recently identified as the most efficacious therapy for treatments of CUDs., Materials and Methods: Quality of life, efficacy, and safety parameters for CM were obtained from previous literature. Costs were calculated from a societal perspective. Our model predicted the utility benefit based on quality-adjusted life-years (QALYs) and incremental-cost-effectiveness ratio resulting from two treatments on a one-, two-, and five-year timeline., Results: On a one-year timeline, DBS would need to impart a success rate (ie, cocaine free) of 70% for it to yield the same utility benefit (0.492 QALYs per year) as CM. At no success rate would DBS be more cost-effective (incremental-cost-effectiveness ratio <$50,000) than CM during the first year. Nevertheless, as DBS costs are front loaded, DBS would need to achieve success rates of 74% and 51% for its cost-effectiveness to exceed that of CM over a two- and five-year period, respectively., Conclusions: We find DBS would not be cost-effective in the short term (one year) but may be cost-effective in longer timelines. Since DBS holds promise to potentially be a cost-effective treatment for CUDs, future randomized controlled trials should be performed to assess its efficacy., (Copyright © 2021 International Neuromodulation Society.

Background: Uterine artery embolization is an effective and safe technique for the treatment of uterine fibroids, but its use remains controversial for women who wish to procreate., Objective: This study aimed to study the clinical, anatomic, and obstetrical results of uterine artery embolization in patients of childbearing age not eligible for myomectomy., Study Design: This was a retrospective cohort study of 398 female patients under the age of 43 years who were treated by uterine artery embolization between 2003 and 2017 for symptomatic fibroids and/or adenomyosis. Uterine artery embolization was performed according to a standardized procedure (fertility-sparing uterine artery embolization technique), with ovarian protection in the event of dangerous utero-ovarian anastomosis. Magnetic resonance imaging and pelvic ultrasounds were performed before and after uterine artery embolization., Results: The overall clinical success rate (ie, resolution of preembolization symptoms such as heavy menstrual bleeding, iron-deficiency anemia, pelvic pressure) was 91.2%, and there were no major complications. One year after uterine artery embolization, we observed a mean 73% reduction in myoma volume. A total of 108 patients (49.3%) presented with dangerous utero-ovarian anastomosis and 33 (14.5%) benefited from ovarian protection. In our group, there were 148 pregnancies and 109 live births; 74 children were born at term; 23 were born preterm, on average at 35.12±2.78 weeks. Including preterm births, the mean birthweight and birth length of the children were within normal limits. Restoration of uterine anatomy and ovarian protection were identified as the main predictive factors for obstetrical success. Restoration was also a major predictive factor for clinical success and was associated with a lower rate of miscarriage., Conclusion: This study provided detailed clinical and obstetrical outcomes for 398 female patients who underwent uterine artery embolization for fibroid treatment; it contributes to the identification of anatomic and technical factors that could have an impact on fertility after uterine artery embolization. Further controlled clinical trials are needed to confirm our findings and reevaluate this procedure's indications and limitations for women with a desire to procreate., (Copyright © 2021 Elsevier Inc.
