Background: Androgen deprivation therapy, the mainstay of treatment for patients with advanced prostate cancer, can be either medical or surgical. Surgery has cost benefits compared to medical treatment. In this study, we evaluated the use of simple and epididymal-sparing orchiectomy in 2 different practice settings for the treatment of metastatic prostate cancer. Methods: We reviewed patients who underwent surgical castration for metastatic prostate cancer between 2011 and 2022. The primary outcome was achieving castration-level total testosterone of <50 ng/dL. We also compared the characteristics of patients who were seen at a public academic teaching hospital vs those who were seen at a private community hospital (oncology group practice), and we evaluated the impact of orchiectomy approach (simple vs epididymal-sparing orchiectomy) on patient outcomes. Results: We analyzed 101 patients who underwent orchiectomy: 40 (39.6%) at a public academic teaching hospital and 61 (60.4%) at a private community hospital (oncology group practice). Of these patients, 81 (80.2%) underwent simple orchiectomy and 20 (19.8%) underwent epididymal-sparing orchiectomy. Forty-nine patients (48.5%) had previously received medical androgen deprivation therapy, 9 (18.4%) of whom had medication adherence issues. Patient age, race, and marital status differed significantly between hospital facilities. The overall surgical complication rate was 3.0%. Postoperative total testosterone levels were available for 81 patients, drawn a median of 57 days after surgery [IQR 30, 123]. All patients had castrate-level total testosterone (median 10 ng/dL [IQR 9, 19]) postoperatively, with no differences seen between surgery location (P = 0.84) or surgical technique (P = 0.90). Conclusion: Simple or epididymal-sparing orchiectomy is safe and effective for surgical castration and is an alternative to medical androgen deprivation therapy for patients diagnosed with metastatic prostate cancer regardless of the practice demographics.

Background: Obesity, defined as a body mass index ≥30 kg/m², is epidemic in the United States and is associated with increased risks of adverse events. Studies have examined the role of maternal obesity on the incidence of instrumental vaginal delivery, but the results are divided. However, these analyses used frequentist tests that risk false discovery. The purpose of this retrospective study was to quantify the association of maternal obesity to the need for instrumental delivery with measures of effect size. Measures of effect size allow assessment of the impact of clinical risk factors on outcomes of interest. Methods: All parturients aged ≥18 years in active labor at our facility from January 2018 to May 2019 were entered into this study. Patient demographics, previously reported comorbidities, and obstetric parameters were collected and analyzed to determine the clinical impact of maternal obesity on the incidence of instrumental delivery. One effect size measure, risk differences, was used to quantify the clinical effect of maternal obesity on the need for instrumental delivery. A generalized linear model was used to standardize the measures of effect size of previously reported comorbidities, including maternal obesity, and to determine their association with the need for instrumental delivery. Results: The incidences of chronic and gestational hypertension, preeclampsia, chronic diabetes, and reactive airway disease were higher in parturients with maternal obesity. Risk differences due to maternal obesity were observed in parturients presenting with shoulder dystocia but not in those who underwent oxytocin induction or in nulliparous parturients. Following regression analysis, maternal obesity did not clinically impact the need for instrumental delivery. Conclusion: These findings suggest that maternal obesity did not have a clinical impact on the need for instrumental delivery.

Background: The rapid evolution of neuroendovascular intervention has resulted in the inclusion of endovascular techniques as a core competency in neurosurgical residency training. Methods: We conducted a literature review of studies involving the training of neurosurgical residents in cerebrovascular and endovascular neurosurgery. We reviewed the evolution of cerebrovascular neurosurgery and the effects of these changes on residency, and we propose interventions to supplement contemporary training. Results: A total of 48 studies were included for full review. Studies evaluated trainee education and competency (29.2%, 14/48), neuroendovascular training models (20.8%, 10/48), and open cerebrovascular training models (52.1%, 25/48), with some overlap. We used a qualitative analysis of reviewed reports to generate a series of suggested training supplements to optimize cerebrovascular education. Conclusion: Cerebrovascular neurosurgery is at a crossroads where trainees must develop disparate skill sets with inverse trends in volume. Continued longitudinal exposure to both endovascular and open cerebrovascular surgical fields should be mandated in general resident education, and blended learning tactics using adjunct simulation systems and models should be incorporated with didactics to both optimize learning and alleviate restraints placed by decreased volume and autonomy.

Background: The use of electronic vapor products (EVPs) increases the risks of nicotine addiction, drug-seeking behavior, mood disorders, and avoidable premature morbidities and mortality. We explored temporal trends in EVP use among US adolescents. Methods: We used data from the Youth Risk Behavior Survey for school grades 9 through 12 from 2015 (earliest available data) to 2021 (the most recently available data) from the US Centers for Disease Control and Prevention (n=57,006). Results: Daily use of EVPs increased from 2.0% in 2015 to 7.2% in 2019, a greater than 3.5-fold increase. Although the percentage decreased to 5.0% in 2021, it was still a >2.5-fold increase since 2015. In 2015, the percentage of EVP use was significantly higher in boys (2.8%) than girls (1.1%). By 2021, the percentage of EVP use was higher in girls (5.6%) than boys (4.5%), a 1.24-fold increase. In addition, the percentage of EVP use in 2021 was higher in White youth (6.5%) vs Black (3.1%), Asian (1.2%), and Hispanic/Latino (3.4%) youth compared to 2015, but White and Black adolescents had the highest increases of approximately 3.0-fold between 2015 and 2021. Adolescents in grade 12 had the highest percentages of EVP use at all periods. Conclusion: These data show alarming statistically significant and clinically important increases in EVP use in US adolescents in school grades 9 through 12. The magnitude of the increases may have been blunted by coronavirus disease 2019, a hypothesis that requires direct testing in analytic studies. These trends create clinical and public health challenges that require targeted interventions such as mass media campaigns and peer interventions to combat the influences of social norms that promote the adoption of risky health behaviors during adolescence.
