From Alpha to Omicron: A Radiation Oncology Network's Biocontainment-Based COVID-19 Experience.

Purpose: To develop the safest possible environment for treating urgent patients with COVID-19 requiring radiation, we describe the unique construction of negative air pressure computed tomography simulator and linear accelerator treatment vaults in addition to screening, delay, and treatment protocols and their evolution over the course of the COVID-19 pandemic. Methods and Materials: Construction of large high-efficiency particulate air filter air-flow systems into existing ductwork in computed tomography simulator rooms and photon and proton treatment vaults was completed to create negative-pressure rooms. An asymptomatic COVID-19 screening protocol was implemented for all patients before initiation of treatment. Patients could undergo simulation and/or treatment in the biocontainment environments according to a predefined priority scale and protocol. Patients treated under the COVID-19 protocol from June 2020 to January 2022 were retrospectively reviewed. Results: Negative air-flow environments were created across a regional network, including a multi-gantry proton therapy unit. In total, 6525 patients were treated from June 2020 through January 2022 across 5 separate centers. The majority of patients with COVID-19 had radiation treatment deferred when deemed safe. A total of 42 patients with COVID-19, who were at highest risk of an adverse outcome should there be a radiation delay, were treated under the COVID-19 biocontainment protocol in contrast to those who were placed on treatment break. For 61.9% of patients, these safety measures mitigated an extended break during treatment. The majority of patients (64.3%) were treated with curative intent. The median number of biocontainment sessions required by each patient was 6 (range, 1-15) before COVID-19 clearance and resumption of treatment in a normal air-flow environment. Conclusions: Constructing negative-pressure environments and developing a COVID-19 biocontainment treatment protocol allowed for the safe treatment of urgent radiation oncology patients with COVID-19 within our department and strengthens future biopreparedness. These biocontainment units set a high standard of safety in radiation oncology during the current or for any future infectious outbreak.

Association of Iatrogenic Infarcts With Clinical and Cognitive Outcomes in the Evaluating Neuroprotection in Aneurysm Coiling Therapy Trial.

BACKGROUND AND OBJECTIVES: Small iatrogenic brain infarcts are often seen on diffusion-weighted MRI (DWI) following surgical or endovascular procedures, but there are few data on their clinical effects. We examined the association of iatrogenic infarcts with outcomes in the ENACT (Evaluating Neuroprotection in Aneurysm Coiling Therapy) randomized controlled trial of nerinetide in patients undergoing endovascular repair of intracranial aneurysms. METHODS: In this post hoc analysis, we used multivariable models to evaluate the association of the presence and number of iatrogenic infarcts on DWI with neurologic impairment (NIH Stroke Scale [NIHSS]), functional status (modified Rankin Scale [mRS]), and cognitive and neuropsychiatric outcomes (30-minute test battery) at 1-4 days and 30 days postprocedure. We also related infarct number to a z score-derived composite outcome score using quantile regression. RESULTS: Among 184 patients (median age 56 years [interquartile range (IQR) 50-64]), 124 (67.4%) had postprocedural DWI lesions (median 4, IQR 2-10.5). Nerinetide treatment was associated with fewer iatrogenic infarcts but no overall significant clinical treatment effects. Patients with infarcts had lower Mini-Mental State Examination (MMSE) scores at 2-4 days (median 28 vs 29, adjusted coefficient [acoef] -1.11, 95% CI -1.88 to -0.34, p = 0.005). Higher lesion counts were associated with worse day 1 NIHSS (adjusted odds ratio for NIHSS ≥1: 1.07, 1.02-1.12, p = 0.009), day 2-4 mRS (adjusted common odds ratio [acOR] 1.05, 1.01-1.09, p = 0.005), and day 2-4 MMSE (acoef -0.07, -0.13 to -0.003, p = 0.040) scores. At 30 days, infarct number remained associated with worse mRS (acOR 1.04, 1.01-1.07, p = 0.016) and Hopkins Verbal Learning Test (HVLT) delayed recall scores (acoef -0.21, -0.39 to -0.03, p = 0.020). Patients with infarcts trended towards lower 30-day Digit Symbol Substitution Test (DSST) scores (acoef -3.73, -7.36 to -0.10, p = 0.044). Higher lesion count was associated with worse composite outcome scores at both 1-4 days and 30 days (30-day acoef -0.12, 95% CI -0.21 to -0.03, p = 0.008). Among those with infarcts, day 1 NIHSS and day 2-4 mRS correlated with 30-day NIHSS, DSST, HVLT, and mRS scores, whereas day 2-4 MMSE correlated with 30-day NIHSS and DSST scores (Spearman ρ 0.47, p = 0.001). DISCUSSION: Iatrogenic brain infarcts were associated with subtle differences in postprocedural (1-4 days) and 30-day outcomes on different measures in this middle-aged cohort, with earlier dysfunction correlating with later differences.

Establishing a Deaf and American Sign Language Inclusive Residency Program.

Improving diversity in residency programs has been increasingly emphasized as a means to address gender, racial, and ethnic disparities in medicine. However, limited attention has been given to the potential benefits of training physicians with differences other than gender or race and ethnicity. Americans with a disability represent about 27% of the U.S. population, whereas 1%-3% of physician trainees report having a disability. In 2013, a national survey identified only 86 physicians or trainees reporting deafness or hearing loss as a disability. To date, there are no published strategies on how to create an inclusive program for Deaf trainees. Herein, the authors report on the development of a Deaf and American Sign Language (ASL) inclusive residency program that can serve as an academic model for other programs, in any medical specialty, seeking to create an accessible training program for Deaf physicians and that can be adapted for trainees with other disabilities. In March 2017, the radiation oncology residency program at Johns Hopkins University matched an ASL-signing Deaf resident who would begin the program in July 2018. In preparation, department leadership engaged key stakeholders and leaders within the university's health system and among the department faculty, residents, and staff as well as the incoming resident to create an ASL inclusive program. A 5-step transition process for the training program was ultimately developed and implemented. The authors focused on engaging the Deaf trainee and interpreters, engaging health system and departmental leadership, contracting a training consultant and developing oral and written training materials for faculty and staff, and optimizing the workspace via accommodations. Through collaborative preparation, a Deaf and ASL-signing resident was successfully integrated into the residency program. The proposed 5-step transition process provides an effective, engaging model to encourage other institutions that are seeking to employ similar inclusivity initiatives.

Assessment of Radiation Oncology Nurse Education in the United States.

PURPOSE: Nurses in the radiation oncology (RO) clinic have a critical role in the management of patients receiving radiation therapy. However, limited data exist regarding the exposure of nurses to RO during training and the current educational needs of practicing RO nurses. This study assesses nurses' prior RO education, participation in national training efforts, and perceived educational needs. METHODS AND MATERIALS: A web-based survey using a 5-point Likert-type scale was distributed to RO nurses at 3 academic medical centers. Questions focused on prior education experiences, clinical areas of strength/weakness, and perceived value of future educational interventions. Likert-type scores are reported as median (interquartile range), and a Kruskal-Wallis test was conducted to assess for significant differences in responses. RESULTS: The survey response rate was 39 of 54 (72%). Respondents were 90% female and trained at 30 nursing schools in 17 states. Only 5% of nurses reported a curriculum in nursing school with RO content, and nearly all (97%) received their RO education on the job. Forty-one percent of nurses completed the Oncology Nursing Society radiation therapy certificate course, and only 5% completed the American Society for Radiation Oncology nursing module. Nurses felt most confident in the overall management of patients with breast (4 [3-4]), prostate (4 [3-5]), and central nervous system (4 [3-4]) cancers and least confident for lymphoma (3 [2-4]), gynecologic (3 [2-4]), and head and neck cancers (3 [2-4]; P < .01). Nurses rated didactic lectures from physicians (5 [3-5]), shadowing RO residents (4 [3-5]), and working with simulation therapists (4 [3-5]) as valuable components to include in a training curriculum (P = .08). CONCLUSIONS: Nursing school exposure to RO is limited, and only a minority of RO nurses complete RO-specific training or certification available from national organizations. This study identifies several areas of perceived clinical nursing strengths and weaknesses that can be used to inform the design of future RO nursing educational programs.

Interventional Radiation Oncology (IRO): Transition of a magnetic resonance simulator to a brachytherapy suite.

PURPOSE: As a core component of a new gynecologic cancer radiation program, we envisioned, structured, and implemented a novel Interventional Radiation Oncology (IRO) unit and magnetic resonance (MR)-brachytherapy environment in an existing MR simulator. METHODS AND MATERIALS: We describe the external and internal processes required over a 6-8 month time frame to develop a clinical and research program for gynecologic brachytherapy and to successfully convert an MR simulator into an IRO unit. RESULTS: Support of the institution and department resulted in conversion of an MR simulator to a procedural suite. Development of the MR gynecologic brachytherapy program required novel equipment, staffing, infrastructural development, and cooperative team development with anesthetists, nurses, therapists, physicists, and physicians to ensure a safe and functional environment. Creation of a separate IRO unit permitted a novel billing structure. CONCLUSIONS: The creation of an MR-brachytherapy environment in an MR simulator is feasible. Developing infrastructure includes several collaborative elements. Unique to the field of radiation oncology, formalizing the space as an Interventional Radiation Oncology unit permits a sustainable financial structure.

Using Yoga Nidra to Improve Stress in Psychiatric Nurses in a Pilot Study.

Given today's hurried and stressful heathcare system, nurses need mechanisms to take care of themselves, promote their own wellness, and build resilience in managing sick patients. Yoga is one such mechanism; it can decrease anxiety and improve sleep and quality of life. In this pilot study, nine nurses participated in 6 weekly sessions of yoga nidra. Measures of sleep, stress, and muscle fatigue were obtained to determine whether yoga had a positive impact upon quality of life and stress. Although based on a small sample of nurses, results indicated positive findings for both perceived stress level and muscle fatigue. This pilot study demonstrated the potential benefit of yoga in stress reduction, muscle tension, and self-care in nurses.

Safety and efficacy of NA-1 in patients with iatrogenic stroke after endovascular aneurysm repair (ENACT): a phase 2, randomised, double-blind, placebo-controlled trial.

BACKGROUND: Neuroprotection with NA-1 (Tat-NR2B9c), an inhibitor of postsynaptic density-95 protein, has been shown in a primate model of stroke. We assessed whether NA-1 could reduce ischaemic brain damage in human beings. METHODS: For this double-blind, randomised, controlled study, we enrolled patients aged 18 years or older who had a ruptured or unruptured intracranial aneurysm amenable to endovascular repair from 14 hospitals in Canada and the USA. We used a computer-generated randomisation sequence to allocate patients to receive an intravenous infusion of either NA-1 or saline control at the end of their endovascular procedure (1:1; stratified by site, age, and aneurysm status). Both patients and investigators were masked to treatment allocation. The primary outcome was safety and primary clinical outcomes were the number and volume of new ischaemic strokes defined by MRI at 12-95 h after infusion. We used a modified intention-to-treat (mITT) analysis. This trial is registered with ClinicalTrials.gov, number NCT00728182. FINDINGS: Between Sept 16, 2008, and March 30, 2011, we randomly allocated 197 patients to treatment-12 individuals did not receive treatment because they were found to be ineligible after randomisation, so the mITT population consisted of 185 individuals, 92 in the NA-1 group and 93 in the placebo group. Two minor adverse events were adjudged to be associated with NA-1; no serious adverse events were attributable to NA-1. We recorded no difference between groups in the volume of lesions by either diffusion-weighted MRI (adjusted p value=0·120) or fluid-attenuated inversion recovery MRI (adjusted p value=0·236). Patients in the NA-1 group sustained fewer ischaemic infarcts than did patients in the placebo group, as gauged by diffusion-weighted MRI (adjusted incidence rate ratio 0·53, 95% CI 0·38-0·74) and fluid-attenuated inversion recovery MRI (0·59, 0·42-0·83). INTERPRETATION: Our findings suggest that neuroprotection in human ischaemic stroke is possible and that it should be investigated in larger trials. FUNDING: NoNO Inc and Arbor Vita Corp.

Effects of preoperative education on spinal surgery patients.

BACKGROUND: Preoperative patient education (PE) has been used by many institutions to deal with patient anxiety, pain control, and overall satisfaction. Although the literature suggests PE's effectiveness in joint reconstruction, data are missing in spinal surgery. METHODS: We retrospectively analyzed patients having elective spinal surgery who underwent PE (spine pre-care class) from October 2009 to March 2010. Of the 155 patients surveyed, 77 (49.7%) attended the class whereas 78 (50.3%) did not. RESULTS: Of the participants in the pre-care class, 96% were satisfied with their pain management versus 83% in the control group (P =.02). There was also a trend for better overall satisfaction in the pre-care class group (91% vs 85%; P > .05, multiple regression analysis). Elderly women tend to be less satisfied with pain management and overall treatment. CONCLUSIONS: Implementation of PE has had a positive impact on patient satisfaction, especially in terms of pain management.

Risk for elevated blood lead levels in 3- and 4-year-old children.

OBJECTIVE: We conducted a study to evaluate the relation between environmental, demographic, and medical risk factors and late-onset childhood lead poisoning, defined as children who were poisoned at age 3 or older. METHODS: We performed a retrospective case-control study of 262 children whose test results showed non-elevated (<10 microg/dl) blood lead levels (BLLs) before age 2 but levels > or =10 microg/dl after age 3 and of 300 control children who had non-elevated BLL test results before age 2 and also after age 3. The target population was children receiving care at MetroHealth Medical Center in Cleveland, OH. We modeled the association between demographic and clinical risk factors and BLLs > or =10 microg/dl after age 3. Covariates considered were race, gender, body mass index, immunization status, mean corpuscular volume, hematocrit, red cell volume distribution width (RDW), red blood count, hemoglobin, baseline BLL result, and time between the baseline and second BLL test. RESULTS: Case children were more likely to be male (P < 0.0001), black (P = 0.0189) and to have a high RDW defined as > or =14.5 % (P = 0.0083). On the basis of the final model, children with BLLs 7-9 microg/dl before age 2 and again after a follow-up BLL test (<21 months) were more likely to become lead poisoned than were control children. The risk of black children developing lead poisoning increased over time, regardless of the child's first BLL test result. CONCLUSIONS: Although national recommendations are to test children's blood lead levels at ages 1 and 2, children living in high-risk areas with such risk factors should have a blood lead test at these older ages.
