- Abstract
There has been increasing pressure on healthcare providers to exhibit restraint when prescribing opioids for pain control. However, data that characterizes the differences between orthopaedic providers and their accompanying prescription rates is not well developed. This study accessed Medicare Provider Utilization and Payment Data from 2015 to collect the number of prescriptions for opioid-based medications administered by orthopaedic surgeons across the country. A total of 19,410 orthopaedic providers were identified as opioid prescribers from the 2015 Medicare Part D Database. Providers averaged an opioid prescription every 10.9 days, with 94.7% of prescribers (18,387) having written more than 10 opioid prescriptions. Regionally, the Southern United States had the highest percentage of providers prescribing an opioid greater than 10 times at 96.4%. Female orthopaedic surgeons prescribed just over half the number of scripts that male surgeons did (79.4 vs. 154.2, p < 0.001). (Journal of Surgical Orthopaedic Advances 32(3):199-201, 2023).

- Abstract
Objectives: This study sought to define contemporary rates of drug eluting stent (DES) usage in patients with chronic kidney disease (CKD)., Background: Among patients with CKD undergoing percutaneous coronary interventions (PCIs), outcomes are superior for those who receive DES compared to those who receive bare metal stents (BMSs). However, perceived barriers may limit the use of DES in this population., Methods: All adult PCI cases from the NCDR CathPCI Registry involving coronary stent placement between July 1, 2009 and December 31, 2015 were analyzed. The rate of DES usage was then compared among four groups, stratified by CKD stage (I/II, III, IV, and V). Subgroup analysis was conducted based on PCI status and indication. Cases were linked to Medicare claims data to assess 1-year mortality., Results: A total of 3,650,333 PCI cases met criteria for analysis. DES usage significantly declined as renal function worsened (83.0%, 79.9%, 75.6%, and 75.6%, respectively, in the four CKD stages; p < .001). DES usage was universally lower across the four groups in the setting of ST-Elevation Myocardial Infarction (STEMI) (70.6%, 66.5%, 58.7%, 58.0%; p < .001) and higher in the setting of elective PCI (87.6%, 84.9%, 82.3%, 77.9%; p < .0001). DES was associated with improved 1-year survival, and usage increased over time across each group., Conclusions: DESs are underutilized in patients with advanced renal dysfunction. Although DES usage has increased over time, variation still exists between patients with normal renal function and those with CKD., (© 2020 Wiley Periodicals, Inc.)

- Abstract
Background: Synovial sarcoma (SyS) is a rare malignancy that is typically located on the limbs and occurs predominantly in adolescents. A study in a large population for SyS comparing subtypes has not yet been reported., Methods: National Cancer Institute's Surveillance, Epidemiology, and End Results database was queried for patients diagnosed with SyS between January 1975 and December 2016. Patients were classified demographically according to gender, age, race/ethnicity, and marital status, and they were also classified by tumors, subtypes, localization, grade, year of diagnosis, laterality, type of treatment, and follow-up results., Results: A total of 3228 patients were included, with a mean age of 39.3 ± 18.8 (range: 1-94), of which 1521 (47.1%) were females and 1707 (52.9%) were males. According to its subtypes, 47.2% were SyS not otherwise specified, 32.3% were spindle cell, 19.9% were biphasic, and 0.6% were epithelioid type. The overall survival period is 138.0 (95% confidence interval: 113.2-162.8) months. Survival duration was found to be significantly different between groups according to gender (log-rank test; p < 0.001), age groups (log-rank test; p < 0.001), race (log-rank test; p = 0.001), marital status (log-rank test; p < 0.001), tumor subtypes (log-rank test; p < 0.001), tumor location (log-rank test; p < 0.001), tumor laterality (log-rank test; p < 0.001), date of diagnosis (log-rank test; p = 0.025), tumor grade (log-rank test; p < 0.001), historic stage (log-rank test; p < 0.001), state of chemotherapy (log-rank test; p < 0.001), state of radiotherapy (log-rank test; p < 0.001), presence of metastasis (log-rank test; p < 0.001), and total number of malignant tumors (log-rank test; p < 0.001)., Conclusion: Male gender, being colored individual, being over 35 years at the time of diagnosis, epithelioid type, non-head and neck region localization is associated with poor prognosis. While radiotherapy improves survival, benefit of chemotherapy is unclear., Level of Evidence: III retrospective analysis.

- Abstract
Background and objectives: Epithelioid sarcoma (ES) is an aggressive malignancy scarcely reported on due to its rarity. This study is a review of its traits and features of prognosis and survival by analyzing both the literature and a national cancer database. Methods: Data were acquired from both the Survival, Epidemiology, and End Results database and literature. 1, 5, and 10-year Disease Specific Survival rates and hazard ratios (HR) were determined. Data were split into pre-2000 (<2000) and post-2000 (>2000) groups. Overall survival, recurrence, and metastasis rates were obtained. Results: Ninety hundred and ninety eight and 992 cases of ES were identified from the database and literature, respectively. Age, anatomical site, grade, TNM staging, treatment modality and year of diagnosis were demonstrated to be independent predictors of survival. Overall 5- and 10-year survival were 60.4% and 50.2%, respectively. Overall recurrence and metastasis rates were 63.4% and 40.3%. Using cases diagnosed prior to 2000 as reference, those diagnosed after 2000 had a worse prognosis (HR: 1.55). Conclusions: We report using the largest cohort of ES to date. Despite ES's often dismal prognosis, there are factors associated with better outcomes. A worsening survival over the years warrants further investigation into this sarcoma.

- Abstract
Background: Common risky behaviors among college-aged young adults include risky sexual behaviors and substance use., Purpose: This study examines the protective effects of Judaism on students' engagement in risky behaviors, building on a body of research on the protective effects of religious beliefs on risky health behaviors., Methods: Validated and reliable measures were used to assess religiosity and risky behaviors through anonymous surveys. Data was collected in Fall 2018 from a small cohort (N = 15) of Jewish day school students., Results: Females had overall higher rates of risky behaviors such as drinking or using drugs before sex (27% compared to 13% for males), not using condoms (62% to 0% for males), and higher rates of binge drinking (62% to 20% for males)., Conclusion: Higher religiosity was more associated with delayed sexual activity than substance use behaviors. Judaism and religiosity were more strongly associated with the male participants than the female., Practice Implications: Since the participants still had low rates of condom use and other high risk behaviors despite speaking with their healthcare providers, the health care community must better educate adolescents and young adults on the health and social consequences of such risky activities, both in formal education programs during middle and high school, and in office visits., (Copyright © 2019 Elsevier Inc.

- Abstract
Objectives: This multicenter pragmatic investigation assessed outcomes following clinical implementation of CYP2C19 genotype-guided antiplatelet therapy after percutaneous coronary intervention (PCI)., Background: CYP2C19 loss-of-function alleles impair clopidogrel effectiveness after PCI., Methods: After clinical genotyping, each institution recommended alternative antiplatelet therapy (prasugrel, ticagrelor) in PCI patients with a loss-of-function allele. Major adverse cardiovascular events (defined as myocardial infarction, stroke, or death) within 12 months of PCI were compared between patients with a loss-of-function allele prescribed clopidogrel versus alternative therapy. Risk was also compared between patients without a loss-of-function allele and loss-of-function allele carriers prescribed alternative therapy. Cox regression was performed, adjusting for group differences with inverse probability of treatment weights., Results: Among 1,815 patients, 572 (31.5%) had a loss-of-function allele. The risk for major adverse cardiovascular events was significantly higher in patients with a loss-of-function allele prescribed clopidogrel versus alternative therapy (23.4 vs. 8.7 per 100 patient-years; adjusted hazard ratio: 2.26; 95% confidence interval: 1.18 to 4.32; p = 0.013). Similar results were observed among 1,210 patients with acute coronary syndromes at the time of PCI (adjusted hazard ratio: 2.87; 95% confidence interval: 1.35 to 6.09; p = 0.013). There was no difference in major adverse cardiovascular events between patients without a loss-of-function allele and loss-of-function allele carriers prescribed alternative therapy (adjusted hazard ratio: 1.14; 95% confidence interval: 0.69 to 1.88; p = 0.60)., Conclusions: These data from real-world observations demonstrate a higher risk for cardiovascular events in patients with a CYP2C19 loss-of-function allele if clopidogrel versus alternative therapy is prescribed. A future randomized study of genotype-guided antiplatelet therapy may be of value., (Copyright © 2018 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Older women are less likely to receive standard of care treatment for breast cancer., Methods: We examined variables that affected the outcome of elderly patients ≥70 years old among 1,470 patients with invasive cancer with positive sentinel lymph nodes (SLNs)., Results: Elderly patients were less likely to undergo mastectomy, completion axillary node dissection (ALND), adjuvant chemotherapy, and radiotherapy (RT) following breast-conserving therapy (BCT) compared with patients <70 years old. The 5-year risk of disease progression and cumulative incidence of breast cancer-specific deaths were not significantly different for both groups. On multivariate analysis, hormone receptor-negative status, number of metastatic lymph nodes, high nuclear grade, and tumor size were the factors independently associated with increased risk of disease progression., Conclusions: Tumor factors were the primary determinants of breast cancer outcomes in our cohort. Elderly patients are less likely to receive aggressive surgical interventions and adjuvant therapy because of perceived life expectancy., (Copyright © 2011 Elsevier Inc. All rights reserved.)

- Abstract
Self-transcendence is a process that can help individuals reestablish well-being after experiencing a significant, life-altering event. In this study, we sought to identify the relationship between self-transcendence and depression in individuals who lost loved ones to HIV/AIDS and to describe and compare self-transcendence, self-transcendence variables of acceptance and spirituality, and depression among bereaved individuals who created AIDS Memorial Quilt panels with those who did not. The findings support Reed's self-transcendence theory, with inverse correlations between self-transcendence and depression obtained from both the total group and the panel makers. Significant differences were also found between certain self-transcendence variables and depression among the study participants related to gender and ethnicity. In addition, thematic analysis of panel maker interviews revealed five themes: Quilt panel making provides validation, Quilt panel making creates a living memory, liberating acceptance of loss, community of survivors, and connection to a higher power. These findings assist in understanding the complexities of the grief process and support the usefulness of Quilt panel making as an intervention for coping with grief related to HIV/AIDS.
