Call to Action: Structural Racism as a Fundamental Driver of Health Disparities: A Presidential Advisory From the American Heart Association.

Structural racism has been and remains a fundamental cause of persistent health disparities in the United States. The coronavirus disease 2019 (COVID-19) pandemic and the police killings of George Floyd, Breonna Taylor, and multiple others have been reminders that structural racism persists and restricts the opportunities for long, healthy lives of Black Americans and other historically disenfranchised groups. The American Heart Association has previously published statements addressing cardiovascular and cerebrovascular risk and disparities among racial and ethnic groups in the United States, but these statements have not adequately recognized structural racism as a fundamental cause of poor health and disparities in cardiovascular disease. This presidential advisory reviews the historical context, current state, and potential solutions to address structural racism in our country. Several principles emerge from our review: racism persists; racism is experienced; and the task of dismantling racism must belong to all of society. It cannot be accomplished by affected individuals alone. The path forward requires our commitment to transforming the conditions of historically marginalized communities, improving the quality of housing and neighborhood environments of these populations, advocating for policies that eliminate inequities in access to economic opportunities, quality education, and health care, and enhancing allyship among racial and ethnic groups. Future research on racism must be accelerated and should investigate the joint effects of multiple domains of racism (structural, interpersonal, cultural, anti-Black). The American Heart Association must look internally to correct its own shortcomings and advance antiracist policies and practices regarding science, public and professional education, and advocacy. With this advisory, the American Heart Association declares its unequivocal support of antiracist principles.

Defining a Patient Population With Cirrhosis: An Automated Algorithm With Natural Language Processing.

OBJECTIVES: The objective of this study was to use natural language processing (NLP) as a supplement to International Classification of Diseases, Ninth Revision (ICD-9) and laboratory values in an automated algorithm to better define and risk-stratify patients with cirrhosis. BACKGROUND: Identification of patients with cirrhosis by manual data collection is time-intensive and laborious, whereas using ICD-9 codes can be inaccurate. NLP, a novel computerized approach to analyzing electronic free text, has been used to automatically identify patient cohorts with gastrointestinal pathologies such as inflammatory bowel disease. This methodology has not yet been used in cirrhosis. STUDY DESIGN: This retrospective cohort study was conducted at the University of California, Los Angeles Health, an academic medical center. A total of 5343 University of California, Los Angeles primary care patients with ICD-9 codes for chronic liver disease were identified during March 2013 to January 2015. An algorithm incorporating NLP of radiology reports, ICD-9 codes, and laboratory data determined whether these patients had cirrhosis. Of the 5343 patients, 168 patient charts were manually reviewed at random as a gold standard comparison. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of the algorithm and each of its steps were calculated. RESULTS: The algorithm's PPV, NPV, sensitivity, and specificity were 91.78%, 96.84%, 95.71%, and 93.88%, respectively. The NLP portion was the most important component of the algorithm with PPV, NPV, sensitivity, and specificity of 98.44%, 93.27%, 90.00%, and 98.98%, respectively. CONCLUSIONS: NLP is a powerful tool that can be combined with administrative and laboratory data to identify patients with cirrhosis within a population.

Association between YouTube® videos and health literacy with postoperative healthcare utilization following pediatric urologic surgery: A randomized trial.

INTRODUCTION: Limited caregiver health literacy has been associated with poorer health outcomes in pediatric patients and may limit caregiver understanding of printed education resources. Postoperative healthcare utilization may be related to confusion about instructions or complications. OBJECTIVE: To correlate caregiver health literacy and educational video intervention with postoperative healthcare utilization following ambulatory pediatric urologic surgery. STUDY DESIGN: From July through December 2021, a randomized double-blinded trial assessed postoperative healthcare utilization following pediatric urologic surgery. Caregivers were randomized to receive standardized postoperative counseling and printed instructions (control) or access to English-language educational YouTube® videos with standardized postoperative counseling and printed instructions (intervention). Medical record abstraction was completed 30 days following surgery to identify postoperative healthcare utilization with calls, messages, add-on clinic visits, or presentation for urgent or emergent care, and postoperative complications. RESULTS: Target enrollment was achieved with 400 caregivers with 204 in the intervention and 196 in the control groups. There was a 32.5 % overall rate of postoperative healthcare utilization. Health literacy was inversely associated with total postoperative healthcare utilization (p < 0.001). There was no difference in the incidence of postoperative healthcare utilization between the control and intervention groups (p = 0.623). However, on sub-analysis of caregivers with postoperative healthcare utilization (Summary Figure), there were fewer total occurrences in the intervention group (intervention median 1, IQR 1,2.3; control median 2, IQR 1,3; p < 0.001). For caregivers with limited health literacy, there was a greater associated reduction in median calls from 2 (IQR 0,2) to 0 (IQR 0,0.5) with video intervention (p = 0.016). On multivariate analysis, total postoperative healthcare utilization was significantly associated with limited caregiver health literacy (OR 1.08; p = 0.004), English as preferred language (OR 0.68; p = 0.018), and older patient age (OR 0.95; p = 0.001). DISCUSSION: Current resources for postoperative education are limited as resources can be written above recommended reading levels and families can have difficulty recalling information discussed during postoperative counseling. Video intervention is an underutilized resource that can provide an additional resource to families with visual and auditory aids and be accessed as needed. CONCLUSION: Caregiver health literacy was inversely associated with postoperative healthcare utilization. There was no difference in the incidence of postoperative healthcare utilization with video intervention. However, on subgroup analysis, supplemental videos were associated with fewer occurrences of postoperative healthcare utilization, especially in caregivers with limited health literacy. On multivariate regression, health literacy, preferred language, and patient age were significantly associated with total postoperative healthcare utilization.

Blood and urine biomarkers in prostate cancer: Are we ready for reflex testing in men with an elevated prostate-specific antigen?

OBJECTIVE: There is no consensus on the role of biomarkers in determining the utility of prostate biopsy in men with elevated prostate-specific antigen (PSA). There are numerous biomarkers such as prostate health index, 4Kscore, prostate cancer antigen 3, ExoDX, SelectMDx, and Mi-Prostate Score that may be useful in this decision-making process. However, it is unclear whether any of these tests are accurate and cost-effective enough to warrant being a widespread reflex test following an elevated PSA. Our goal was to report on the clinical utility of these blood and urine biomarkers in prostate cancer screening. METHODS: We performed a systematic review of studies published between January 2000 and October 2020 to report the available parameters and cost-effectiveness of the aforementioned diagnostic tests. We focus on the negative predictive value, the area under the curve, and the decision curve analysis in comparing reflexive tests due to their relevance in evaluating diagnostic screening tests. RESULTS: Overall, the biomarkers are roughly equivalent in predictive accuracy. Each test has additional clinical utility to the current diagnostic standard of care, but the added benefit is not substantial to justify using the test reflexively after an elevated PSA. CONCLUSIONS: Our findings suggest these biomarkers should not be used in binary fashion and should be understood in the context of pre-existing risk predictors, patient's ethnicity, cost of the test, patient life-expectancy, and patient goals. There are more recent diagnostic tools such as multi-parametric magnetic resonance imaging, polygenic single-nucleotide panels, IsoPSA, and miR Sentinel tests that are promising in the realm of prostate cancer screening and need to be investigated further to be considered a consensus reflexive test in the setting of prostate cancer screening.

Using Wearable Technology to Measure the Association Between Neck Posture and Pain During Urologic Open and Robotic Surgery.

Purpose: Chronic neck pain is the most prevalent work-related musculoskeletal injury among surgeons. Urologists may be at higher risk of neck injury due to extended time spent operating in deep anatomical structures during open surgery. Our goal was to use wearable technology to quantify the relationship between neck posture and pain during open and robotic surgery. Materials and Methods: Urologic attendings and residents who spent at least 1 day per week performing surgery for >6 hours took part in this study. Neck posture was measured in real time during surgery using inertial measurement devices attached at the occipital protuberance and seventh cervical vertebrae. Self-reported neck pain scores were obtained throughout their workday. Results: Thirty participants and 202 hours of surgery were included in the study (21 attendings, 9 residents). There was a significant association between neck posture and pain (p = 0.04). Surgeons performing open procedures spent on average 147 minutes with their head in neck flexion postures of 30° or greater compared with 68 minutes for those performing robotic procedures (p = 0.007). Surgeons performing open procedures reported a mean change in neck pain of 2.0 on the numeric analogue scale, compared with 1.3 for those performing robotic procedures (p = 0.04). Conclusions: Real-time measurements of neck flexion during urologic surgery shows that greater duration and higher degree of neck flexion were associated with increased neck pain. Raising awareness about ergonomics in the operating room during residency will enable future generations of surgeons to make conscious decisions regarding their neck posture in surgery.

Underutilization of Surgical Standard of Care for Insured Men with Invasive Penile Cancer.

PURPOSE: Prior studies of mixed insurance populations have demonstrated poor adherence to surgical standard of care (SOC) for penile cancer. We used data from the Surveillance, Epidemiology and End Results (SEER) cancer registry linked to Medicare to calculate SOC adherence to surgical treatment of penile cancer in insured men over the age of 65, focusing on potential social and racial disparities. METHODS: This is an observational analysis of patients with T2-4 penile cancer of any histologic subtype without metastasis in the SEER-Medicare database (2004-2015). SOC was defined as penectomy (partial or radical) with bilateral inguinal lymph node dissection (ILND) based on the National Comprehensive Cancer Network guidelines. We calculated proportions of those receiving SOC and constructed multivariate models to identify factors associated with receiving SOC. RESULTS: A total of 447 men were included. Of these men, 22.1% (99/447) received SOC while 18.8% (84/447) received no treatment at all. Only 23.3% (104/447) had ILND while 80.9% (362/447) underwent total or partial penectomy. Race and socioeconomic status (SES) were not associated with decreased SOC. Increasing age (OR 0.93, 95%CI:0.89-0.96), Charlson Comorbidity Index score ≥ 2 (OR 0.53, 95%CI:0.29-0.97), and T3-T4 disease (OR 0.34, 95%CI:0.18-0.65) were associated with not receiving SOC on adjusted analysis. CONCLUSIONS: Rates of SOC are low among insured men 65 years of age or older with invasive penile cancer, regardless of race or SES. This finding is largely driven by low rates of ILND. Strategies are needed to overcome barriers to SOC treatment for men with invasive penile cancer.

De novo Hepatocellular Carcinoma after Liver Transplantation.

Liver transplantation is the definitive therapy for patients with advanced liver disease and its complications. Patients who are transplanted with a diagnosis of hepatocellular carcinoma (HCC) are at risk of recurrent cancer, and these patients are monitored on a regular basis for recurrence. In contrast, de novo HCC following liver transplantation is a very rare complication, and recipients without HCC at the time of transplantation are not screened. We describe the clinical features of de novo HCC over a decade after achieving a sustained viral response with treatment of hepatitis C and two decades after liver transplantation. Our case highlights the necessity of screening for HCC in the post-transplant patient with advanced liver disease even after viral clearance.

Screening and detection advances in magnetic resonance image-guided prostate biopsy.

Multiparametric magnetic resonance imaging (MRI) has provided a method for visualizing prostate cancer. MRI-ultrasonography fusion allows prostate biopsy to be performed quickly, on an outpatient basis, using the transrectal technique. Targeted biopsies are more sensitive for detection of prostate cancer than nontargeted, systematic biopsies and detect more significant prostate cancers and fewer insignificant cancers than conventional biopsies. A negative MRI scan should not defer biopsy. Two groups who will especially benefit from targeted prostate biopsy are men with low-risk lesions in active surveillance and men with increased prostate-specific antigen levels and previous negative conventional biopsies.
