    Abstract This is a pilot study to assess whether racial disparities exist in time to initiation and completion of external beam pelvic radiation therapy and brachytherapy in cervical cancers treated with definitive chemoradiation. A retrospective analysis was conducted on all cervical cancer patients treated with definitive radiotherapy between 2006 and 2016 at a single institution. Patient demographics including age, race, insurance status and stage at diagnosis were obtained. Analyses were performed according to the following definitions of wait times: interval from pathologic diagnosis of cervical cancer to (Siegel et al., 2016) initiation of radiation therapy, (Yoo et al., 2017) completion of external beam radiation therapy and (DeSantis et al., 2016) completion of external beam radiation therapy plus brachytherapy if indicated. Of 50 women, 21 self-identified as white, 25 as black and 4 as Hispanic. Due to small numbers, Hispanic women were included with black women as a non-white group. The average age was 52 years for women in this cohort. Mean days to initiation of radiation therapy were 41.8 days: 33.7 days among white patients versus 47.8 days for non-white patients (p-value 0.101). Mean days from diagnosis to completion of external beam pelvic radiation therapy were 81.3 days: 70.9 days among white patients versus 88.9 days among non-white patients (p-value 0.006). Non-white patients were more likely to have public insurance, which was also associated with a longer time to completion of radiation treatment. We conclude that non-white patients experienced delays to completing external beam radiation therapy, which was no longer present after adjusting for insurance status.

    Abstract Background: Time to clinical follow-up after an abnormal mammogram may be a significant factor contributing to breast cancer health disparities.
    Objective: Evaluate time to follow-up in a cross-sectional cohort of African American and Hispanic women who obtained mammogram screening at a county facility.
    Methods: Time to follow-up was assessed in days after an abnormal mammogram to subsequent clinical care in a cross-sectional study of 74 women.
    Results: The median number of days until clinical follow-up after an abnormal mammogram for women in the study was 30 days (Range: 0-357 days). There was a statistically significant difference in the time-to-biopsy among women who had incomplete mammograms and women who had comorbid conditions.
    Conclusions: This data indicates that county services provide clinical follow-up in compliance with recommended guidelines of 30 days. However, women with incomplete mammograms and comorbid conditions may be at a higher risk of experiencing delays in diagnosis and treatment.

    Abstract Study objective: To evaluate rates of urologic injury in patients who underwent robotic hysterectomy compared with laparoscopic, vaginal, and open hysterectomy.
    Design: A retrospective analysis (Canadian Task Force classification II-2).
    Setting: Henry Ford Health System, 2013 to 2016.
    Patients: Women who underwent robotic, vaginal, laparoscopic, and open abdominal hysterectomy.
    Interventions: Robotic hysterectomy, laparoscopic-assisted vaginal hysterectomy, total laparoscopic hysterectomy, laparoscopic supracervical hysterectomy, vaginal hysterectomy, and abdominal hysterectomy.
    Measurements and main results: To identify patients with urologic injury, a departmental database for quality improvement was searched for reported urologic injuries. In addition, patients who had urology consultation within 90 days of hysterectomy were screened for injury. A total of 3114 hysterectomies were identified by retrospective chart review. One thousand eighty-eight robotic, 782 laparoscopic, 304 vaginal, and 940 abdominal hysterectomies were analyzed for urologic complications. A total of 27 injuries were confirmed (7 during laparoscopic hysterectomy, 10 during robotic hysterectomy, 1 during vaginal hysterectomy, and 9 during abdominal hysterectomy). The overall rate of urologic injury was 0.87% with a 0.55% risk of bladder injury and a 0.32% risk of injury to the ureter. When the route of hysterectomy was taken into account, the risk of urologic injury was 0.92% for robotic hysterectomy, 0.90% for laparoscopic hysterectomy, 0.33% for vaginal hysterectomy, and 0.96% for open hysterectomy. The mean body mass index (BMI) for all patients was 32.7 kg/m
    Conclusion: Rates of urologic injury with robotic hysterectomy are similar to those of laparoscopic hysterectomy in our population. BMI was not significantly different in patients who had urologic injuries. Surgeon volume was not associated with risk for urologic injury.

    Abstract We describe a patient with Class C diabetes who presented for nonstress testing at 36 weeks and 4 days of gestation with nonreassuring fetal heart tones (NRFHT) and oligohydramnios. Upon delivery, thrombosis of the umbilical cord was grossly noted. Pathological analysis of the placenta revealed chorangiosis, vascular congestion, and 40% occlusion of the umbilical vein. Chorangiosis is a vascular change of the placenta that involves the terminal chorionic villi. It has been proposed to result from longstanding, low-grade hypoxia in the placental tissue and has been associated with such conditions such as diabetes, intrauterine growth restriction (IUGR), and hypertensive conditions in pregnancy. To characterize chorangiosis and its associated obstetric outcomes we identified 61 cases of "chorangiosis" on placental pathology at Henry Ford Hospital from 2010 to 2015. Five of these cases were omitted due to lack of complete records. Among the 56 cases, the cesarean section rate was 51%, indicated in most cases for nonreassuring fetal status. Thus, we suggest that chorangiosis, a marker of chronic hypoxia, is associated with increased rates of cesarean sections for nonreassuring fetal status because of long standing hypoxia coupled with the stress of labor.
