Physician Judgment and Circulating Biomarkers Predict 28-Day Mortality in Emergency Department Patients
OBJECTIVES/OBJECTIVE:To determine whether biomarkers of endothelial activation and inflammation provide added value for prediction of in-hospital mortality within 28 days when combined with physician judgment in critically ill emergency department patients. DESIGN/METHODS:Prospective, observational study. SETTING/METHODS:Two urban, academic emergency departments, with ≈80,000 combined annual visits, between June 2016 and December 2017. PATIENTS/METHODS:Admitted patients, greater than 17 years old, with two systemic inflammatory response syndrome criteria and organ dysfunction, systolic blood pressure less than 90 mm Hg, or lactate greater than 4.0 mmol/L. Patients with trauma, intracranial hemorrhage known prior to arrival, or without available blood samples were excluded. INTERVENTIONS/METHODS:Emergency department physicians reported likelihood of in-hospital mortality (0-100%) by survey at hospital admission. Remnant EDTA blood samples, drawn during the emergency department stay, were used to measure angiopoietin-1, angiopoietin-2, tumor necrosis factor receptor-1, interleukin-6, and interleukin-8. MEASUREMENTS AND MAIN RESULTS/RESULTS:We screened 421 patients and enrolled 314. The primary outcome of in-hospital mortality within 28 days occurred in 31 (9.9%). When predicting the primary outcome, the best biomarker model included angiopoietin-2 and interleukin-6 and performed moderately well (area under the curve, 0.72; 95% CI, 0.69-0.75), as did physician judgment (area under the curve, 0.78; 95% CI, 0.74-0.82). Combining physician judgment and biomarker models improved performance (area under the curve, 0.85; 95% CI, 0.82-0.87), with area under the curve change of 0.06 (95% CI, 0.04-0.09; p < 0.01) compared with physician judgment alone. CONCLUSIONS:Predicting in-hospital mortality within 28 days among critically ill emergency department patients may be improved by including biomarkers of endothelial activation and inflammation in combination with emergency department physician judgment.

Natural Language Processing for Identification of Incidental Pulmonary Nodules in Radiology Reports
PURPOSE/OBJECTIVE:To develop natural language processing (NLP) to identify incidental lung nodules (ILNs) in radiology reports for assessment of management recommendations. METHOD AND MATERIALS/METHODS:We searched the electronic health records for patients who underwent chest CT during 2014 and 2017, before and after implementation of a department-wide dictation macro of the Fleischner Society recommendations. We randomly selected 950 unstructured chest CT reports and reviewed manually for ILNs. An NLP tool was trained and validated against the manually reviewed set, for the task of automated detection of ILNs with exclusion of previously known or definitively benign nodules. For ILNs found in the training and validation sets, we assessed whether reported management recommendations agreed with Fleischner Society guidelines. The guideline concordance of management recommendations was compared between 2014 and 2017. RESULTS:The NLP tool identified ILNs with sensitivity and specificity of 91.1% and 82.2%, respectively, in the validation set. Positive and negative predictive values were 59.7% and 97.0%. In reports of ILNs in the training and validation sets before versus after introduction of a Fleischner reporting macro, there was no difference in the proportion of reports with ILNs (108 of 500 [21.6%] versus 101 of 450 [22.4%]; P = .8), or in the proportion of reports with ILNs containing follow-up recommendations (75 of 108 [69.4%] versus 80 of 101 [79.2%]; P = .2]. Rates of recommendation guideline concordance were not significantly different before and after implementation of the standardized macro (52 of 75 [69.3%] versus 60 of 80 [75.0%]; P = .43). CONCLUSION/CONCLUSIONS:NLP reliably automates identification of ILNs in unstructured reports, pertinent to quality improvement efforts for ILN management.

Identification of Racial Inequities in Access to Specialized Inpatient Heart Failure Care at an Academic Medical Center
BACKGROUND:Racial inequities for patients with heart failure (HF) have been widely documented. HF patients who receive cardiology care during a hospital admission have better outcomes. It is unknown whether there are differences in admission to a cardiology or general medicine service by race. This study examined the relationship between race and admission service, and its effect on 30-day readmission and mortality Methods: We performed a retrospective cohort study from September 2008 to November 2017 at a single large urban academic referral center of all patients self-referred to the emergency department and admitted to either the cardiology or general medicine service with a principal diagnosis of HF, who self-identified as white, black, or Latinx. We used multivariable generalized estimating equation models to assess the relationship between race and admission to the cardiology service. We used Cox regression to assess the association between race, admission service, and 30-day readmission and mortality. RESULTS:Among 1967 unique patients (66.7% white, 23.6% black, and 9.7% Latinx), black and Latinx patients had lower rates of admission to the cardiology service than white patients (adjusted rate ratio, 0.91; 95% CI, 0.84-0.98, for black; adjusted rate ratio, 0.83; 95% CI, 0.72-0.97 for Latinx). Female sex and age >75 years were also independently associated with lower rates of admission to the cardiology service. Admission to the cardiology service was independently associated with decreased readmission within 30 days, independent of race. CONCLUSIONS:Black and Latinx patients were less likely to be admitted to cardiology for HF care. This inequity may, in part, drive racial inequities in HF outcomes.

Interventional Pain Treatments in the Management of Oncologic Patients with Thoracic Spinal Tumor-Related Pain: A Case Series [Case Report]
BACKGROUND:Advanced tumors of the thoracic spine are difficult to treat and can lead to complex pain syndromes. Following conventional oncologic treatments, pharmacologic therapy may be insufficient to manage pain. Minimally invasive interventional procedures offer alternatives to treat malignant thoracic spinal pain. METHODS:Thirteen patients with metastatic disease and poorly controlled thoracic axial and/or radicular pain were identified via a retrospective chart review. Patients were either treated with radiation, surgery, chemotherapy, or a combination of these. Then, the patients were organized into groups based on their diagnoses, anatomical disease locations, symptoms, prior treatments, and interventional pain procedures offered. RESULTS:All cases of intercostal nerve, costotransverse junction, erector spinae plane, and paravertebral blocks resulted in pain relief without any reported complications. A patient who received a thoracic epidural injection had a complete resolution of pain when combined with radiation therapy two weeks after the injection. One patient who underwent repeat thoracic epidurals eventually had an intrathecal pump placement resulting in reduced opioid usage. Finally, one patient who received a thoracic medial branch block with a relief of thoracic axial pain reported greater pain relief with a medial branch nerve cryoablation. CONCLUSION/CONCLUSIONS:We propose a treatment algorithm to manage patients with thoracic spinal tumor-related pain. Interventional thoracic axial procedures may be safe and efficacious pain treatments for cancer patients. This article is protected by copyright. All rights reserved.

Surveillance-Based Estimate of the Prevalence of Chronic Hepatitis B Virus Infection, New York City, 2016
OBJECTIVES:Chronic hepatitis B virus (HBV) infection is a lifelong infection that can cause serious liver damage and liver cancer. The last surveillance-based prevalence estimate of chronic HBV infection in New York City was 1.2% in 2008; however, it did not account for persons with undiagnosed infection. The objective of this study was to calculate the prevalence of chronic HBV infection, including undiagnosed infection, for 2016 by using surveillance data and literature-based information. METHODS:We calculated the number of persons with diagnosed chronic HBV infection (2000-2016) who were alive and living in New York City in 2016 by using routine surveillance data. We estimated the percentage of persons with undiagnosed chronic HBV infection by using birth region-specific percentages from the literature, weighted by the proportion of the New York City population with diagnosed chronic HBV infection from the same birth region. We identified minimum, maximum, and most likely values for the percentage with undiagnosed chronic HBV infection to generate 95% certainty limits (CLs) of the prevalence estimate. RESULTS:The prevalence of chronic HBV infection in 2016, including undiagnosed infection, in New York City was 2.7% (95% CL, 2.2%-3.6%), representing approximately 230 000 persons. The prevalence of diagnosed chronic HBV infection was 1.5%. The estimated prevalence among non-US-born residents was 6.9% (95% CL, 5.4%-8.9%). CONCLUSIONS:The current burden of chronic HBV infection in New York City, especially for non-US-born residents, is substantial. A renewed focus and dedication of resources is required to increase the number of new diagnoses and improve provider capacity to care for the large number of persons with chronic HBV infection.

A Systematic Review of Advocacy Curricula in Graduate Medical Education
BACKGROUND:Professionalism standards encourage physicians to participate in public advocacy on behalf of societal health and well-being. While the number of publications of advocacy curricula for GME-level trainees has increased, there has been no formal effort to catalog them. OBJECTIVE:To systematically review the existing literature on curricula for teaching advocacy to GME-level trainees and synthesize the results to provide a resource for programs interested in developing advocacy curricula. METHODS:A systematic literature review was conducted to identify articles published in English that describe advocacy curricula for graduate medical education trainees in the USA and Canada current to September 2017. Two reviewers independently screened titles, abstracts, and full texts to identify articles meeting our inclusion and exclusion criteria, with disagreements resolved by a third reviewer. We abstracted information and themes on curriculum development, implementation, and sustainability. Learning objectives, educational content, teaching methods, and evaluations for each curriculum were also extracted. RESULTS:After reviewing 884 articles, we identified 38 articles meeting our inclusion and exclusion criteria. Curricula were offered across a variety of specialties, with 84% offered in primary care specialties. There was considerable heterogeneity in the educational content of included advocacy curriculum, ranging from community partnership to legislative advocacy. Common facilitators of curriculum implementation included the American Council for Graduate Medical Education requirements, institutional support, and preexisting faculty experience. Common barriers were competing curricular demands, time constraints, and turnover in volunteer faculty and community partners. Formal evaluation revealed that advocacy curricula were acceptable to trainees and improved knowledge, attitudes, and reported self-efficacy around advocacy. DISCUSSION:Our systematic review of the medical education literature identified several advocacy curricula for graduate medical education trainees. These curricula provide templates for integrating advocacy education into GME-level training programs across specialties, but more work needs to be done to define standards and expectations around GME training for this professional activity.

Incidence of CKD with TDF and non-TDF containing antiretroviral regimens by baseline D:A:D CKD risk in people living with HIV (PLWH) [Meeting Abstract]
Purpose: Given recent evidence that the risk of renal toxicities with TDF may increase with coadministration of a pharmacoenhancer (Hill 2018), we assessed the risk of chronic kidney disease (CKD) associated with TDF and non- TDF containing regimens by D:A:D CKD risk and boosting.
Method(s): ART-naive adults initiating treatment with eGFR>=60 mL/min/ 1.73 m2 (last eGFR within 12 months pre-initiation) were identified in the OPERA cohort. CKD was defined as>=2 consecutive eGFR<60 mL/min/1.73 m2, >90 days apart. The associations between TDF use, baseline D:A:D CKD risk, and incident CKD were assessed with unadjusted incidence rates (IR, Poisson regression) and adjusted survival analyses (pooled logistic regression). Secondary analysis evaluated the contribution of pharmacoenhancers.
Result(s): Of 9,802 PLWH included, 6,222 initiated TDF (76% low-risk D:A:D CKD score, 16% medium-risk, 8% high-risk) and 3,580 did not (79% low-risk, 13% medium-risk, 8% high-risk; Table 1); 40-47% initiated a boosted regimen (Table 2). Overall, 125 incident CKD events occurred over 24,382 person-years of follow-up. Within strata of D:A:D risk score, IRs were similar by TDF exposure, with high baseline CKD risk associated with highest incidence regardless of TDF use (Figure 1). Compared to the low-risk group without TDF, there was no statistical difference in odds of incident CKD in the medium-risk group without TDF (aOR: 2.32, 95% CI: 0.72, 7.52) or the low-risk group with TDF (aOR: 0.55, 95% CI: 0.19, 1.54; Figure 2). Odds of incident CKD did not differ by pharmacoenhancer exposure, with or without TDF.
Conclusion(s): In this large cohort of ART-naive PLWH, incident CKD following ART initiation was relatively infrequent and was strongly associated with baseline CKD risk. TDF-containing regimens did not appear to increase the risk of CKD in those with a low baseline D:A:D CKD risk, the largest group of naive PLWH, and may remain a viable treatment option.

Early results of the emulate therapeutics HaeloTM system in pediatric brain tumors [Meeting Abstract]
BACKGROUND: The EMulate Therapeutics Halo system is an investigational non-sterile, non-invasive, non-thermal, non-ionizing, portable, home-use medical device that uses a specific, localized ultra-low radio frequency energy (ulRFER) cognate for the treatment of pediatric brain tumors.
METHOD(S): Sixteen patients with brain tumors consisting of diffuse midline glioma/diffuse intrinsic pontine glioma (DMG/DIPG, n=14), recurrent medulloblastoma (n=1), or anaplastic astrocytoma (n=1) - were treated with the Halo under FDA's single-patient compassionate use pathway, as protocol deviations in a glioblastoma trial, or under TGA's Special Access Scheme. Baseline information and on-treatment safety and exposure data were collected.
RESULT(S): Patients ranged in age from 4 to 28 years (median = 8 years) and were diagnosed 91 - 1399 days (median = 397 days) prior to treatment with the Halo system. Patients were treated for 2 - 52 weeks (median = 15 weeks), with 4 patients still alive (all with a diagnosis of DMG/DIPG), and 3 still on treatment (ranging 18 - 52 weeks). Two out of the 16 patients reported mild-moderate adverse events - one patient reported nausea, fatigue, and excessive sleepiness, and one patient reported vomiting. No device-related serious adverse events were reported. Other adverse events reported were generally associated with progressive disease. Unsolicited, anecdotal reports from some parents/caregivers noted improvements in mobility, speech, and visual acuity while on treatment.
CONCLUSION(S): The Halo system appears to be safe and feasible for the treatment of pediatric brain tumors. Given that therapy is delivered non-invasively and no device-related serious adverse events were reported, further prospective study of the investigational device is warranted

US nursing and midwifery research capacity building opportunities to achieve the United Nations sustainable development goals
To meet the United Nations Sustainable Development Goals (SDGs) in the United States, research by nurses and midwives has a real opportunity to make a significant impact. This paper identifies opportunities to strengthen research capacity in the United States amongst nurses and midwives in ways that will help meet the SDGs and ensure its sustainability. Research capacity means that in a country, there are individuals and teams capable of defining problems, setting priorities, establishing objectives for the goals of the research study, and following rigorous scientific procedures. By strengthening U.S. research capacity by addressing critical weaknesses in content expertise, nursing and midwifery's voices in policy dialogues, and global research initiatives will be have greater assurance of being included.

The Covenant
Burnout among doctors appears to be at epidemic proportions these days, with concomitant gushing prescriptions for wellness and resilience. But in reality, most doctors are not burned out, in the traditional sense of the word: most love taking care of patients and want nothing more than to be able to do just that. The source of the agony is the profession-or rather the corporatization of the profession-that has so impinged upon the doctors' ability to practice medicine. Doctors placed their trust in the medical profession, but that trust has been roundly trounced. So, rather than prescribe Pilates classes for overstressed doctors, it is time for the medical profession-and the health care industry that has subsumed it-to get a check-up.
