Abstract
Purpose An effective didactic curriculum is a cornerstone for a successful residency program, as it is the basis upon which residents acquire the necessary knowledge and perspective to provide high-quality, evidence-based care. Here we describe our success in creating a standardized curriculum in clinical radiation oncology - one that was well-received and led to significantly improved performance on the national in-service examination. Methods and Materials One-hundred and fifty topics were outlined in accordance with the American Board of Radiology; to accommodate this breadth of material, didactic frequency was increased from biweekly to daily. As a clinical correlate to these sessions, a teaching library of over 100 real-world cases was compiled for individual learning. Finally, comprehensive dosimetric constraints were compiled to aid residents in radiation therapy plan evaluation. To evaluate these curricular changes, anonymous questionnaires were provided to all residents and faculty, and de-identified resident clinical performance from the annual in-service examination was analyzed. Results Before the introduction of the standardized curriculum, the mean clinical percentage on the in-service examination was 46%, equivalent to the 17th percentile. Within 2 years of implementation of the new curriculum, both the mean percentage and percentile were significantly improved, with the mean percentage correct at 69.3% and the mean percentile at the 59th percentile (P < .001 and P = .034, respectively). Feedback showed the curriculum to be well-received and used frequently outside of standard didactic hours. Conclusions This is the first report of the creation of a standardized curriculum and outcomes in radiation oncology. Although there are certainly developmental challenges, addressing these barriers creates an education model that effectively imparts knowledge, fosters multidisciplinary thinking, and prepares residents for the diverse challenges of clinical practice. We present our institutional experience with the intent of publishing this curriculum on a national platform in the coming years.

Abstract
Background Peritoneal carcinomatosis is a particularly rare presentation of prostate cancer. Here we report a rare clinical case of surgically identified peritoneal carcinomatosis at the time of a planned robotic prostatectomy in a patient with a history of prostatic urethral lift procedure. Case presentation A 72-year-old man, with a history of urinary retention managed with tamsulosin, presented to his local urologist. Prostatic urethral lift procedures were performed for symptom management. After a definitive uptrend in his prostate-specific antigen (PSA) values, a biopsy was obtained, which demonstrated prostate adenocarcinoma. On presurgical multidisciplinary review, it was presumed that he had very high-risk localized prostate cancer. However, upon initiation of robotically assisted laparoscopic radical prostatectomy (RALP), he was noted to have numerous punctate white plaques on the peritoneum; biopsy of these lesions confirmed metastatic disease-for which the patient was starting on triple therapy per the PEACE-1 trial. The PSA level responded appropriately, decreasing from 16.8 to 0.08. Genetic testing was performed and returned negative for any clinically significant mutations. Conclusion Our patient, diagnosed with peritoneal carcinomatosis during a planned RALP, highlights the importance of vigilant laparoscopic exam prior to this prostatectomy. Multidisciplinary discussion is crucial for individualized and optimal treatment planning.

Abstract
PURPOSE Patients with lung cancer and brain metastases represent a markedly heterogeneous population. Accurate prognosis is essential to optimally individualize care. In prior publications, we described the graded prognostic assessment (GPA), but a GPA for patients with small cell lung cancer (SCLC) has never been reported, and in non-small cell lung cancer (NSCLC), the effect of programmed death ligand 1 (PD-L1) was unknown. The 3-fold purpose of this work is to provide the initial report of an SCLC GPA, to evaluate the effect of PD-L1 on survival in patients with NSCLC, and to update the Lung GPA accordingly. METHODS AND MATERIALS A multivariable analysis of prognostic factors and treatments associated with survival was performed on 4183 patients with lung cancer (3002 adenocarcinoma, 611 nonadenocarcinoma, 570 SCLC) with newly diagnosed brain metastases between January 1, 2015, and December 31, 2020, using a multi-institutional retrospective database. Significant variables were used to update the Lung GPA. RESULTS Overall median survival for lung adenocarcinoma, SCLC, and nonadenocarcinoma was 17, 10, and 8 months, respectively, but varied widely by GPA from 2 to 52 months. In SCLC, the significant prognostic factors were age, performance status, extracranial metastases, and number of brain metastases. In NSCLC, the distribution of molecular markers among patients with lung adenocarcinoma and known primary tumor molecular status revealed alterations/expression in PD-L1 50% to 100%, PD-L1 1% to 49%, epidermal growth factor receptor, and anaplastic lymphoma kinase in 32%, 31%, 30%, and 7%, respectively. Median survival of patients with lung adenocarcinoma and brain metastases with 0, 1% to 49%, and ≥50% PD-L1 expression was 17, 19, and 24 months, respectively (P < .01), confirming PD-L1 is a prognostic factor. Previously identified prognostic factors for NSCLC (epidermal growth factor receptor and anaplastic lymphoma kinase status, performance status, age, number of brain metastases, and extracranial metastases) were reaffirmed. These factors were incorporated into the updated Lung GPA with robust separation between subgroups for all histologies. CONCLUSIONS Survival for patients with lung cancer and brain metastases has improved but varies widely. The initial report of a GPA for SCLC is presented. For patients with NSCLC-adenocarcinoma and brain metastases, PD-L1 is a newly identified significant prognostic factor, and the previously identified factors were reaffirmed. The updated indices establish unique criteria for SCLC, NSCLC-nonadenocarcinoma, and NSCLC-adenocarcinoma (incorporating PD-L1). The updated Lung GPA, available for free at brainmetgpa.com, provides an accurate tool to estimate survival, individualize treatment, and stratify clinical trials.

Abstract
OBJECTIVE Several controversial findings have been reported on treatment outcomes for diabetic stroke patients that received thrombolysis therapy in the hospital. We determined whether the association between telestroke technology, thrombolysis therapy and clinical risk factors in diabetic acute ischemic stroke may result in the inclusion or exclusion or more diabetic ischemic stroke patients for thrombolysis therapy. METHODS Retrospective data that comprises of a total of 3202 acute ischemic stroke patients from a regional stroke registry that contained telestroke and non telestroke patients with a primary diagnosis of acute ischemic stroke of which 312 were identified as diabetic stroke patients were used in this study. Multivariate logistic regression models were used to determine the associated pre-clinical risk factors, and demographics associated with recombinant tissue plasminogen activator (rtPA) therapy in a subset of diabetic acute ischemic stroke patients in the telestroke and non-telestroke settings. RESULTS In the telestroke, only higher International Normalized Ratio (INR) [odds ratio, OR = 0.063 (0.003-1.347, 95% confidence interval (CI)] was associated with exclusion from thrombolysis. Direct admission [OR, 3.141 (1-9.867), 95% CI] and telestroke [OR, 4.87 (1.834-12.928), 95% CI] were independent predictors in the inclusion for thrombolysis therapy. In the non telestroke, older age (> 80 years) [(OR), 0.955 (0.922-0.989), 95% CI], higher blood glucose level [OR, 0.994 (0.99-0.999); 95% CI], higher INR [OR, 0.113 (0.014-0.944); 95% CI], and renal insufficiency [OR, 0.163 (0.033-0.791); 95% CI] were associated with exclusion while higher NIH stroke scale [OR, 1.068 (1.009-1.13); 95% CI] was associated with inclusion for thrombolysis in the non telestroke. CONCLUSION The non-telestroke setting admitted more diabetic stroke patients to the hospital, but more were excluded from thrombolysis therapy when compared with the telestroke setting. Measures to improve clinical risk factors that excluded more diabetic ischemic stroke patients in the non telestroke will improve the use of thrombolysis in the treatment of diabetic acute ischemic stroke patients.

Abstract
BACKGROUND In acute ischemic stroke patients, telestroke technology provides sustainable approaches to improve the use of thrombolysis therapy. How this is achieved as it relates to inclusion or exclusion of clinical risk factors for thrombolysis is not fully understood. We investigated this in a population of hypertensive stroke patients. METHODS Structured data from a regional stroke registry that contained telestroke and non telestroke patients with a primary diagnosis of acute ischemic stroke with history of hypertension were collected between January 2014 and June 2016. Clinical risk factors associated with inclusion or exclusion for recombinant tissue plasminogen activator (rtPA) in the telestroke and non telestroke were identified using multiple regression analysis. Associations between variables and rtPA in the regression models were determined using variance inflation factors while the fitness of each model was determined using the ROC curve to predict the power of each logistic regression model. RESULTS The non telestroke admitted more patients (62% vs 38%), when compared with the telestroke. Although the telestroke admitted fewer patients, it excluded 11% and administered thrombolysis therapy to 89% of stroke patients with hypertension. In the non telestroke group, adjusted odd ratios showed significant associations of NIH stroke scale score (OR = 1.059, 95% CI, 1.025-1.093, P < 0.001) and coronary artery disease (OR = 2.003, 95% CI, 1.16-3.457, P = 0.013) with inclusion, while increasing age (OR = 0.979, 95% CI, 0.961-0.996, P = 0.017), higher INR (OR = 0.146, 95% CI, 0.032-0.665, P = 0.013), history of previous stroke (OR = 0.39, 95% CI, 0.223-0.68, P = 0.001), and renal insufficiency (OR = 0.153, 95% CI, 0.046-0.508, P = 0.002) were associated with rtPA exclusion. In the telestroke, only direct admission to the telestroke was associated with rtPA administration, (OR = 4.083, 95% CI, 1.322-12.611, P = 0.014). CONCLUSION The direct admission of hypertensive stroke patients to the telestroke network was the only factor associated with inclusion for thrombolysis therapy even after adjustment for baseline variables. The telestroke technology provides less restrictive criteria for clinical risk factors associated with the inclusion of hypertensive stroke patients for thrombolysis.

Abstract
BACKGROUND Clinical risk factors related to not administering thrombolysis to acute ischemic stroke patients with incidence dyslipidemia is not clear. This issue was investigated in telestroke and non-telestroke settings. METHODS We analyzed retrospective data collected from a stroke registry to compare exclusion risk factors in the telestroke and non-telestroke. We performed multivariate analysis was performed to identify risk factors that may result in exclusion from rtPA. Variance inflation factors were used to examine multicollinearity and significant interactions between independent variables in the model, while Hosmer-Lemeshow test, Cox & Snell were used to determine the fitness of the regression models. RESULTS A greater number of patients with acute ischemic stroke with incidence dyslipidemia were treated in the non-telestroke (285) when compared with the telestroke network (187). Although non-telestroke admitted more patients than the telestroke, the telestroke treated more patients with rtPA (89.30%) and excluded less (10.70%), while the non-telestroke excluded from rtPA (61.40%). In the non-telestroke, age (adjusted OR, 0.965; 95% CI, 0.942-0.99), blood glucose level (adjusted OR, 0.995; 95% CI, 0.99-0.999), international normalized ratio (adjusted OR, 0.154; 95% CI, 0.031-0.78),congestive heart failure(CHF) (adjusted OR, 0.318; 95% CI, 0.109-0.928), previous stroke (adjusted OR, 0.405; 95% CI, 0.2-0.821) and renal insufficiency (adjusted OR, 0.179; 95% CI, 0.035-0.908) were all directly linked to exclusion from rtPA. In the telestroke, only body mass index (adjusted OR, 0.911; 95% CI, 0.832-0.997) significantly excluded acute ischemic stroke patients with incidence dyslipidemia from thrombolysis therapy. CONCLUSION Despite having more patients with acute ischemic stroke that present incidence dyslipidemia, the non-telestroke patients had more clinical risk factors that excluded more patients from rtPA when compared with telestroke. Future studies should focus on how identified clinical risk factors can be managed to improve the use of rtPA in the non-telestroke setting. Moreover, the optimization of the risk-benefit ratio of rtPA by the telestroke technology can be advanced to the non-telestroke setting to improve the use of thrombolysis therapy.

Abstract
The efficiency of telestroke programs in improving the rates of recombinant
tissue plasminogen activator (rtPA) in stroke patients has been reported.
Previous studies have reported favorable treatment outcomes with the use of
telestroke programs to improve the use of rtPA, but functional outcomes are not
fully understood. This study investigated the effect of telestroke technology in
the administration of rtPA and related functional outcomes associated with
baseline clinical variables. Retrospective data of a telestroke registry were
analyzed. Univariate analysis was used to compare demographic and clinical
variables in the rtPA group and the no rtPA group and between the improved
functional ambulation group and the no improvement group. A stepwise binary
logistic regression identified factors associated with improved functional
outcome in the total telestroke population and in the subset of the telestroke
population who received rtPA. In adjusted analysis and elimination of any
multicollinearity for patients who received rtPA in the telestroke setting,
obesity (odds ratio [OR] = 2.138, 95% confidence interval [CI], 1.164-3.928,
P < .05), higher systolic blood pressure at the time of
presentation (OR = 1.015, 95% CI, 1.003-1.027, P < .05), and
baseline high-density lipoprotein at the time of admission (OR = 1.032, 95% CI,
1.005-1.059, P < .05) were associated with improved
functional outcomes. Increasing age (OR = 0.940, 95% CI, 0.916-0.965,
P < .0001) and higher calculated National Institutes of
Health Stroke Scale (OR = 0.903, 95% CI, 0.869-0.937) were associated with a
poorer outcome in rtPA-treated patients. Telestroke technology improves
functional outcomes at spoke stations where neurological expertise is
unavailable. Further studies are necessary to determine how telestroke
technology can be optimized, especially to improve contraindications and
increase eligibility for thrombolysis therapy.

Abstract
BACKGROUND In a stroke population, women have a worse outcome than men when untreated. In contrast, there is no significant difference in treated patients. In this study, we determined whether clinical variables represent a promising approach to assist in the evaluation of gender differences in a stroke population. METHODS We analyzed data from ischemic stroke patients' ≥18 years-old from the stroke registry on rtPA administration and identified gender differences in clinical factors within inclusion and exclusion criteria in a stroke population that received rtPA. Multivariate analysis was used to adjust for patient demographic and clinical variables. RESULTS Of the 241 eligible stroke patients' thrombolytic therapy, 49.4% were females and 50.6% were males. Of the 422 patients that did not receive rtPA, more women (235) were excluded from rtPA than men (187) (P<0.05). In the male population, exclusion from rtPA was associated with history of a previous stroke (P<0.05, OR=2.028), hypertension (P<0.05, OR=0.519), and NIH stroke score (P<0.0001, OR=0.893). In female stroke patients, exclusion from rtPA was associated with previous history of stroke (P<0.05, OR=2.332), diabetes (P<0.05, OR=1.88) and NIH stroke score (P<0.05, OR=0.916). CONCLUSIONS Despite similarities in different areas of stroke care for both men and women, more women with diabetes, previous history of stroke and higher NIH scores are more likely to be excluded from thrombolytic therapy. Men with a previous history of stroke, hypertension and higher NIH scores are more likely to be excluded rtPA even after adjustment for confounding variables.

Abstract
BACKGROUND The treatment outcomes in the use of rt-PA have been reported. Some studies reported worse outcome in women than men, while others presented opposing data. Using data from a hospital-based stroke registry, we investigated evidence of gender difference and determined exclusion criteria in a stroke population with incidence of hypertension. METHOD In a stroke population of women and men with incident of hypertension from a stroke registry, demographics and clinical factors were compared. Univariate analysis was used to determine gender differences, while multivariable models adjusted for demographic and clinical variables. RESULTS Among the 669 stroke patients with incident of hypertension that were excluded from rt-PA treatment, 362 were female and 307 were male. Female patients with increasing age (OR = 0.956-0.984, P < 0.001), diabetes mellitus (OR = 0.095-0.559, P = 0.001), higher NIH stroke scale score (OR = 1.019-1.090, P = 0.002), previous stroke (OR = 0.337-0.850, P = 0.008), diabetes medication (OR = 1.200-7.724, P = 0.019), and INR (OR = 0.033-0.597, P = 0.008) are more likely to be excluded. Male patients with a history of a previous stroke (OR = 0.265-0.704, P = 0.001), risk of mortality (OR = 0.803-0.950, P = 0.002), higher NIH stroke scale score(OR = 1.101-1.276, P < 0.001), cholesterol reducing medication (OR = 1.191-2.910, P = 0.006), weakness at presentation(OR = 1.207-4.421, P = 0.011), and INR (OR = 0.016-0.243, P < 0.001) are more likely to be excluded. CONCLUSION Women have a worse outcome than men in an untreated acute ischemic stroke population, but when treated, women have a better treatment outcome compared to men. In a hypertensive stroke population, the clinical variables for the exclusion criteria for women and men are significantly different, even after adjustment for confounding variables.

Abstract
Background:
Women and men have a similar incidence for ischemic cerebrovascular disease but women are more frequently hit by stroke later in life than men. It has been shown that women presented with severe stroke symptoms during admission, a poorer prognosis, are likely to have an overall poorer outcome after ischemic stroke when compared with men. However, some studies indicate similarities in outcome for men and women after stroke. Moreover, there is evidence that women treated with tPA benefit at least as much as men. Since a higher diastolic blood pressure increases the risk for a worse prospective functional status in men, but less significance in women, it is not clear whether hypertensive patients with acute ischemic stroke treated will reveal similarity or difference in functional outcome. We investigated this issue in the current study.
Method:
We performed a retrospective analysis of 4500 acute ischemic stroke patients who presented to a health care system between January 2010 and June 2016 and received rt-PA. We develop a new tool to determine the possibility of erasing any gender difference, and identify the most important factor for the poorer outcomes in women or men and whether thrombolysis may counteract this effect.
Results:
Our results reveal that poorer outcomes after stroke and the observed gender differences is due to age, at stroke onset, and that thrombolysis may neutralize this effect.
Conclusion:
The important factor for the poorer outcome and gender differences in hypertensive patients with acute ischemic stroke is mainly due to stroke severity and thrombolysis may play a major role in neutralizing this effect.

Abstract
The repeatability of gait variables is an important consideration in the clinical use of results of quantitative gait analysis. Statistical measures were used to evaluate repeatability of kinematic, kinetic, and electromyographic data waveforms and spatiotemporal parameters of 40 normal subjects. Subjects were evaluated three times on each test day and on three different test days while walking at their preferred or natural speed. Intrasubject repeatability was excellent for kinematic data in the sagittal plane both within a test day as well as between test days. For joint angle motion in the frontal and transverse planes, the repeatability was good within a test day and poor between test days. Poor between-day repeatability of joint angle motion in the frontal and transverse planes was noted to be partly due to variabilities in the alignment of markers. Vertical reaction and fore-aft shear forces were more repeatable than the mediolateral shear force. Sagittal plane joint moments were more repeatable than frontal or transverse plane moments. For electromyographic data, repeatability within a day was slightly better than between test days. In general, the results demonstrate that with the subjects walking at their natural or preferred speed, the gait variables are quite repeatable. These observations suggest that it may be reasonable to base significant clinical decisions on the results of a single gait evaluation.

Abstract
Repeatability is an important consideration for gait analysis data that are being used as an adjunct to clinical decision making. An index of repeatability may be based on a statistical criterion (variance ratio) that reflects similarity of wave forms over a number of identical cycles. The purpose of this study was to use the variance ratio to assess the repeatability of phasic muscle activity recorded with surface and bipolar intramuscular wire electrodes during gait on 10 normal subjects. Variance ratios were calculated using rectified and smoothed electromyographic data recorded simultaneously from the two types of electrodes. Three measures of repeatability (reproducibility, reliability, and constancy--defined as the cycle-to-cycle, run-to-run, and day-to-day repeatability of phasic muscle activity) were used to compare the performance of the two electrode techniques. Results show that the reproducibility and reliability were better for surface electrodes than for intramuscular wire electrodes, and constancy was good for surface electrodes and poor for intramuscular wire electrodes. Repeatability improved with increasing smoothing window lengths but was better for surface electrodes than wire electrodes, irrespective of the smoothing window. This study indicates that surface electrode data represent a more consistent measure of activity of superficial muscles, if comparisons are to be made between gait data from different test days.
