Background
The neutrophil-to-lymphocyte ratio (NLR) is a strong predictor of mortality in patients with colorectal, gastric, hepatocellular, pancreatic, and lung cancer. To date, the utility of NLR to predict mortality in breast cancer patients has not been studied. Therefore, the aim of our study was to determine whether the NLR is predictive of short- and long-term mortality in breast cancer patients.
Methods
Our observational study used an unselected cohort of breast cancer patients treated at the Staten Island University Hospital between January 2004 and December 2006. A total of 316 patients had a differential leukocyte count recorded prior to chemotherapy. Survival status was retrieved from our cancer registry and Social Security death index. Survival analysis, stratified by NLR quartiles, was used to evaluate the predictive value of NLR.
Results
Patients in the highest NLR quartile (NLR > 3.3) had higher 1-year (16% vs 0%) and 5-year (44% vs 13%) mortality rates compared with those in the lowest quartile (NLR < 1.8) (
P
< .0001). Those in the highest NLR quartile were statistically significantly older and had more advanced stages of cancer. After adjusting for the factors affecting the mortality and/or NLR (using two multivariate models), NLR level > 3.3 remained an independent significant predictor of mortality in both models (hazard ratio 3.13,
P
= .01) (hazard ratio 4.09,
P
= .002).
Conclusion
NLR is an independent predictor of short- and long-term mortality in breast cancer patients with NLR > 3.3. We suggest prospective studies to evaluate the NLR as a simple prognostic test for breast cancer.

How the Guardianship System Can Help Address Gun Violence
2020
This article shows how state guardianship law can provide a mechanism for courts to reduce gun violence by removing the right to possess firearms from individuals found, after hearing and due process, to be incapable of safely possessing them. It explores how this often overlooked body of law not only complements extreme risk protection orders where they exist, but can also be used to accomplish a portion of what such orders are designed to do in states that have not authorized them. It concludes by suggesting some modest adjustments to guardianship law and practice that would help ensure that guardianship systems interventions in this arena are fair and effective.

An estimated 2.2 million Americans live in long-term care facilities in the United States. Many of these Americans-perhaps the majority-would vote if voting were accessible to them. Unfortunately, as we show, long-term care residents face systemic disenfranchisement. Specifically, based on our systematic review of nursing home investigation reports, we present disturbing new empirical evidence that demonstrates how burdensome election procedures, profound isolation, and widespread failure by facilities to provide required assistance prevent long-term care residents from voting. Noting that entities traditionally enforcing voting rights have largely ignored these problems, we call for a new wave of voting rights litigation aimed at dismantling barriers to long-term care voter participation and provide a roadmap for how existing law could be employed in such litigation. Finally, continued disenfranchisement of long-term care residents has profound implications not only for older adults and people with disabilities but also for democratic legitimacy. We conclude by unpacking ways in which protecting the voting rights of long-term care residents could be part of a broader agenda of reducing racial and class-based disparities in access to the ballot and sustaining a democratic system of governance.

A Framework for Theoretical Inquiry into Law and Aging
2020
With populations aging worldwide, the need for appropriate and just public policy related to old age is critical. Elder law scholars can support the creation of such policy by advancing the theoretical understanding of the relationship between law and aging — understanding that can help policymakers identify and prioritize goals, and evaluate potential interventions. This Article aims to provide a framework for this work by distilling the core theoretical questions at the intersection of law and aging. It also challenges common assumptions that could pose a barrier to developing a more robust theory of law and aging. Specifically, it argues that scholarship in this area will be most fruitful if it recognizes that the study and practice of “elder law” are intertwined but not a single unified field, that “preferential” treatment of older adults can be a form of discrimination, and that old age is not a universal human experience.

Background
Vagus nerve stimulation is an investigational anti-inflammatory therapy targeting the nervous system to modulate immune activity. This study evaluated the efficacy and safety of transcutaneous auricular VNS (ta-VNS) in patients with pediatric-onset Crohn’s disease (CD) or ulcerative colitis (UC).
Methods
Participants were 10–21 years of age with mild/moderate CD or UC and fecal calprotectin (FC) > 200 ug/g within 4 weeks of study entry. Subjects were randomized to receive either ta-VNS targeting the cymba conchae of the external left ear, or sham stimulation, of 5 min duration once daily for a 2-week period, followed by a cross over to the alternative stimulation for an additional 2 weeks. At week 4, all subjects received ta-VNS of 5 min duration twice daily until week 16. Primary study endpoints were clinical remission, and a ≥ 50% reduction in FC level from baseline to week 16. Heart rate variability measurements and patient-reported outcome questionnaires were completed during interval and week 16 assessments.
Results
Twenty-two subjects were enrolled and analyzed (10 CD, 12 UC). Six of 10 with CD had a wPCDAI > 12.5 and 6/12 with UC had a PUCAI > 10 at baseline, correlating to mild to moderate symptom activity. Among the 12 subjects with active symptomatic disease indices at baseline, clinical remission was achieved in 3/6 (50%) with CD and 2/6 (33%) with UC at week 16. Despite all subjects having FC levels ≥ 200 within 4 weeks of enrollment, five subjects (4 UC, 1 CD) had FC levels < 200 at the baseline visit and were excluded from the FC analysis. Of the remaining 17, median baseline FC was 907 µg/g (IQR 411–2,120). At week 16, 11/17 (64.7%) of those with baseline FC ≥ 200 had a ≥ 50% reduction in FC (95% CI 38.3—85.8). In the UC subjects, there was an 81% median reduction in FC vs baseline (833 µg/g;
p
= 0.03) while in the CD subjects, median reduction in FC at 16 weeks was 51% (357 µg/g;
p
= 0.09). There were no safety concerns.
Conclusion
Noninvasive ta-VNS attenuated signs and symptoms in a pediatric cohort with mild to moderate inflammatory bowel disease.

Missed Opportunities? An Observational Analysis of Lung Cancer Screening Utilization Amongst Patients With Lung Cancer
2022
Lung cancer (LC) is the leading cause of cancer-related deaths worldwide. The U.S. Preventive Services Task Force (USPSTF) and National Comprehensive Cancer Network (NCCN) recommend annual low-dose CT chest (LDCT) for LC screening in high-risk adults who meet appropriate criteria, which primarily focus on age and smoking history. Despite this, screening rates remain low and patients with LC are typically diagnosed at a later stage.
We conducted a single-center retrospective analysis of patients with an established diagnosis of lung cancer to evaluate if screening guidelines were appropriately followed before the cancer diagnosis.
Patients diagnosed with LC between 2016 and 2019 were included in the analysis. Charts were reviewed for demographics, detailed smoking history, as well as histology and stage of LC. Associations between categorical factors and screening were examined using the chi-square test. Associations between continuous and ordinal factors and screening were examined using the Mann–Whitney test.
A total of 530 charts were reviewed, of which 52% met NCCN criteria and 35% met USPSTF criteria. Only 4.0% and 4.8% of patients who met NCCN and USPSTF criteria, respectively, underwent screening. There was a significant association between staging at diagnosis and screening with LDCT. All the patients who had screening CT scans were diagnosed at localized stages of lung cancer in both NCCN and USPSTF groups compared to 49.1% and 48% in eligible subjects that did not undergo screening, respectively.
Our study showed that despite established guidelines for LC screening and insurance coverage, a vast majority of screening-eligible LC patients have never had LDCT. We found that patients who underwent screening as per guidelines were diagnosed at earlier stages of the disease. Ongoing efforts to increase awareness and adherence to LC screening guidelines are needed to improve early detection and reduce LC mortality.

IntroductionCurative intent treatment of head and neck cancer (HNC) is frequently radiation therapy over 7 weeks with concurrent chemotherapy. This regimen is effective but carries a burden of toxicity leading to severe pain and treatment breaks portending inferior outcomes. Conventional palliation methods include opioids, anticonvulsants and local anaesthetics. Breakthrough toxicities are nevertheless ubiquitous and present an urgent unmet need. Ketamine is an inexpensive drug with mechanisms of analgesia outside the opioid pathway including N-methyl-D-aspartate (NMDA) receptor antagonism and a pharmacologically unique property of opioid desensitisation. Systemic ketamine is validated in randomised controlled trials for efficacy in reducing pain and/or opioid burden in the oncologic setting. Literature supports peripherally administered ketamine for pain control without systemic toxicity. These data support our rationale of using ketamine mouthwash to decrease acute toxicity of curative treatment of HNC, the efficacy of which is our aim to elucidate.Methods and analysisThis is a phase II, Simon’s two-stage trial. Patients have pathologically confirmed HNC and an intended regimen of 70 Gy of radiation with concurrent cisplatin. The protocol is initiated on diagnosis of grade 3 mucositis and consists of 2 weeks of 4 times daily (QID) ketamine mouthwash use. The primary endpoint is pain response defined as a combination of pain score and opioid use. 23 subjects will be enrolled in stage 1. If statistical criteria are met, 33 subjects will be enrolled in stage 2. Secondary endpoints include daily pain, daily opioid use, dysphagia at baseline and completion, nightly sleep quality, feeding tube placement and any unscheduled treatment breaks.Ethics and disseminationAll trial data will be stored in an Institutional Review Board (IRB) approved database. The protocol is registered under Northwell IRB registration number #22-0292 and U.S. Food and Drug Administration (FDA) Investigational New Drug (IND) approval has been granted under IND number 161609. Results are intended to be published in an open-source journal and further data, statistics and source documents are available on request.Trial registration numberNCT05331131.

Burnout is prevalent among emergency physicians and may cause physicians to consider leaving the practice of emergency medicine (EM). This study sought to determine whether there is a gender difference in reporting burnout and seriously considering leaving the specialty of EM, and secondarily to explore the factors reported as contributing to burnout.
This was a secondary analysis of the 2014 American Board of Emergency Medicine Longitudinal Survey of Emergency Physicians. We used multiple logistic regression to determine which factors were associated with reporting serious consideration of leaving EM, when stratified by years in practice and adjusting for individual, departmental, and institutional factors.
The response rate was 82%, (n = 868); 22.6% (194) were female and 77.4% (664) were males; and 83.9% (733) White. The mean age of men responding was significantly higher than women (52.7±11.9 vs. 44.9±10.4, p<0.001). Overall, there were no significant gender differences in reporting having had serious thoughts of leaving EM in either unmatched or age-matched analyses. More women reported that burnout was a significant problem, while men more often were equivocal as to whether it was a problem. When stratified by years in practice, mid-career women had a seven-fold increase in the odds ratio (OR) of seriously considered leaving EM, compared to men of similar years in practice (OR 7.07, 95% confidence interval, 2.45-20.39). Autonomy at work, control over working conditions, fair compensation, personal reward, and a sense of ownership were factors associated with a lower rate of reporting considering leaving EM.
Our findings suggest that the intention to leave EM is not more prevalent in women. However, mid-career women more often reported seriously considering leaving the specialty than mid-career men. Further research on the factors behind this finding in mid-career women in EM is needed.

Validation of the IMPROVE‐DD risk assessment model for venous thromboembolism among hospitalized patients with COVID‐19
2021
Antithrombotic guidance statements for hospitalized patients with coronavirus disease 2019 (COVID‐19) suggest a universal thromboprophylactic strategy with potential to escalate doses in high‐risk patients. To date, no clear approach exists to discriminate patients at high risk for venous thromboembolism (VTE).
The objective of this study is to externally validate the IMPROVE‐DD risk assessment model (RAM) for VTE in a large cohort of hospitalized patients with COVID‐19 within a multihospital health system.
This retrospective cohort study evaluated the IMPROVE‐DD RAM on adult inpatients with COVID‐19 hospitalized between March 1, 2020, and April 27, 2020. Diagnosis of VTE was defined by new acute deep venous thrombosis or pulmonary embolism by Radiology Department imaging or point‐of‐care ultrasound. The receiver operating characteristic (ROC) curve was plotted and area under the curve (AUC) calculated. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated using standard methods.
A total of 9407 patients were included, with a VTE prevalence of 2.9%. The VTE rate was 0.4% for IMPROVE‐DD score 0‐1 (low risk), 1.3% for score 2‐3 (moderate risk), and 5.3% for score ≥ 4 (high risk). Approximately 45% of the total population scored high VTE risk, while 21% scored low VTE risk. IMPROVE‐DD discrimination of low versus medium/high risk showed sensitivity of 0.971, specificity of 0.218, PPV of 0.036, and NPV of 0.996. ROC AUC was 0.702.
The IMPROVE‐DD VTE RAM demonstrated very good discrimination to identify hospitalized patients with COVID‐19 as low, moderate, and high VTE risk in this large external validation study with potential to individualize thromboprophylactic strategies.

Lawyers for legal ghosts: the legality and ethics of representing persons subject to guardianship
2016
A person subject to guardianship has been judicially determined to lack legal capacity. Stripped of legal personhood, the individual becomes a ward of the state and his or her decisions are delegated to a guardian. If the guardian abuses that power or the guardianship has been wrongly imposed-as research suggests is not infrequently the case- the person subject to guardianship may rightly wish to mount a legal challenge. However, effectively doing so requires the assistance of an attorney, and persons subject to guardianship typically have not only been declared by a court to be incapable of directing their own affairs but have been stripped of the capacity to contract. As a result, those who wish to challenge the terms and conditions of their guardianship, or even merely to exercise unrelated retained rights, can be stymied because attorneys are unwilling to accept representation for fear that it is unlawful or unethical. Drawing on constitutional law, as well as the law of agency and contract, this Article shows why such representations are, contrary to the assumptions of many attorneys, not merely legally permissible but essential to protect fundamental constitutional rights. It then explores the professional rules governing attorney conduct in order to show how attorneys may ethically represent persons subject to guardianship. Finally, it proposes a modest change to the Model Rules of Professional Conduct to clarify attorneys' duties in this context.
