    Abstract Text line segmentation is a necessary preliminary step before most text transcription algorithms are applied. The leading deep learning networks used in this context (ARU-Net, dhSegment, and Doc-UFCN) are based on the U-Net architecture. They are efficient, but fall under the same concept, requiring a post-processing step to perform instance (e.g., text line) segmentation. In the present work, we test the advantages of Mask-RCNN, which is designed to perform instance segmentation directly. This work is the first to directly compare Mask-RCNN- and U-Net-based networks on text segmentation of historical documents, showing the superiority of the former over the latter. Three studies were conducted, one comparing these networks on different historical databases, another comparing Mask-RCNN with Doc-UFCN on a private historical database, and a third comparing the handwritten text recognition (HTR) performance of the tested networks. The results showed that Mask-RCNN outperformed ARU-Net, dhSegment, and Doc-UFCN using relevant line segmentation metrics, that performance evaluation should not focus on the raw masks generated by the networks, that a light mask processing is an efficient and simple solution to improve evaluation, and that Mask-RCNN leads to better HTR performance.

  4. Article ; Online: Educational Experience Impacts Wellness More than Hours Worked.

    Abstract Objective: The Accreditation Council for Graduate Medical Education has focused its interests on resident wellbeing and the clinical work environment in recent years. Concerns regarding both duty hours as well as service obligations versus education resulted in programs nationwide receiving citations, including ours. This study aimed to evaluate the impact of those 2 factors on surgical residents' general wellbeing, hypothesizing that service obligations would be a stronger predictor.
    Design: We have previously reported on the use of a "Fuel Gauge" tool developed at our institution for monitoring resident wellbeing. We performed a retrospective comparison of prospectively collected cross-sectional survey data comparing the Fuel Gauge to a bimonthly "Service Versus Education" (SVE) report. This report used similar scaling and allowed residents to provide feedback on the balance of the educational quality of their current rotation in comparison to their perception of service obligation. Pearson's correlation was then used to compare those scores with duty hour logs to determine if a relationship could be identified between the 3 measurements.
    Setting: Academic institution of the University of Texas Southwestern in Dallas, Texas.
    Participants: Active general surgery residents (n = 73).
    Results: During the study period, 73 residents filled out both a Fuel Gauge assessment and a SVE assessment at least once, with 273 complete data points available for analysis. Our program's Fuel Gauge median was 4, and our program's median SVE score was 4. Fuel Gauge assessment scores demonstrated a moderate positive correlation with SVE (r = 0.65, p < 0.001), while only a weakly negative association with increasing hours worked (r = -0.15, p = 0.015). SVE also demonstrated a weak negative correlation with hours logged (r = -0.225, p = 0.001).
    Conclusions: While the Accreditation Council for Graduate Medical Education recognizes that multiple factors contribute to resident wellbeing issues, early efforts were focused on limiting excessive duty hours. Examining our institutional data regarding the previously understudied factor of SVE, we indeed found a stronger correlation with resident perception of low educational value rather than excessive work hours contributing to lower Fuel Gauge scores. These data, if verified, should guide program directors in identifying other institutional factors that may more strongly contribute to their own culture of resident wellness.

    Abstract Objectives: Although racial disparities are well documented for common gynecologic surgical procedures, few studies have assessed racial disparities in the surgical treatment of vaginal prolapse. This study aimed to compare the use of obliterative procedures for the treatment of vaginal prolapse across racial and ethnic groups.
    Study design: This is a retrospective cohort study of surgical cases from 2010 to 2018 from the American College of Surgeons National Surgical Quality Improvement Program, a nationally validated database. Cases were identified by Current Procedural Terminology codes. Modified Poisson regression was used to calculate risk ratios and 95% confidence intervals, adjusting for potential confounders selected a priori.
    Results: We identified 45,865 surgical cases, of which 10% involved an obliterative procedure. In the unadjusted model, non-Hispanic Asian and non-Hispanic Black patients were more likely to undergo an obliterative procedure compared with non-Hispanic White patients (risk ratio [95% confidence interval], 2.4 [2.1-2.7] and 1.2 [1.03-1.3], respectively). These relative risks were largely unchanged when controlling for age, body mass index, diabetes, American Society of Anesthesiologists classification, and concurrent hysterectomy.
    Conclusions: Although both obliterative and reconstructive procedures have their respective risks and benefits, the proportion of patients undergoing each procedure differs by race and ethnicity. It is unclear whether such disparities may be attributable to differences in preference or inequity in care.

    Abstract Purpose: We evaluate the cost-effectiveness of prophylactic antibiotic use to prevent catheter-associated urinary tract infections.
    Materials and methods: A decision tree model was used to assess the cost-effectiveness of prophylactic antibiotics in preventing catheter-associated urinary tract infections for patients with a short-term indwelling urinary catheter. The model accounted for incidence of urinary tract infections with and without the use of prophylactic antibiotics, incidence of antibiotic-resistant urinary tract infections, as well as costs associated with diagnosis and treatment of urinary tract infections and antibiotic-resistant urinary tract infections. Costs were calculated from the health care system's perspective. We conducted one-way sensitivity analyses.
    Results: The base case analysis showed that the use of prophylactic antibiotics is cost-saving in preventing catheter-associated urinary tract infections. The use of prophylactic antibiotics resulted in lower costs and higher quality-adjusted life-years compared with no prophylactic antibiotics. Sensitivity analyses showed that the optimal strategy changes to no prophylactic antibiotics when the incidence of urinary tract infections after prophylactic antibiotics exceeds 22% or the incidence of developing urinary tract infections without prophylactic antibiotics is less than 12%. Varying the costs of prophylactic antibiotics, urinary tract infection treatment, or antibiotic-resistant urinary tract infection treatment within a reasonable range did not change the optimal strategy.
    Conclusions: Prophylactic antibiotic use to prevent catheter-associated urinary tract infections is cost-effective under most conditions. These results were sensitive to the likelihood of developing catheter-associated urinary tract infections with and without prophylactic antibiotics. Our results are limited to the cost-effectiveness perspective on this clinical practice.

    Abstract We report on the hitherto unknown compound CeZn2-dGe2 (d approx 0.41). We find this compound to crystallize in a defect version of the well-known CaBe2Ge2 structure type. The phase forms in a Zn/In flux and with Zn-deficiency on one of its crystallographic sites. We find the compound to display uncommon localized Ce-based (4f1) ferromagnetism with a Tc = 6.6 K, a large positive magnetoresistance reaching an MR of approximately 32 % below $T$ = 10 K, and strongly correlated electrons, as evidenced by a Kadowaki-Woods ratio A/gamma^2 close to known heavy fermion compounds. The here discovered material is therefore a promising model platform for the investigation of these entangled interacting and potentially competing electronic states paired with complex crystal chemistry.

    Abstract Background: Urinary voiding dysfunction is reported in many patients with complex regional pain syndrome (CRPS). However, there is a gap in the literature for treating patients with CRPS who develop incontinence symptoms.
    Case: We report a case describing the use of sacral neuromodulation therapy in a patient with urgency urinary and fecal incontinence who had a previously implanted spinal cord stimulator for type 1 CRPS, formerly known as reflex sympathetic dystrophy. Despite initial hesitation and treatment delay, sacral neuromodulation therapy was successful and effective in controlling both fecal and urgency urinary incontinence symptoms for the patient. This intervention continues to provide her with an improved quality of life 10 months after her procedure.
    Conclusions: In this case, there was significant hesitation from the provider and patient to use invasive treatments for incontinence symptoms when the patient's pain symptoms have been well controlled with an existing spinal device. However, in this patient with type 1 CRPS, even in the setting of an existing spinal cord stimulator, sacral neuromodulation therapy was an effective treatment.
