The Department of Veterans' Affairs Depleted Uranium Cohort in the Time of COVID-19: Translating a Traditional Surveillance Protocol to a Telehealth Platform.

OBJECTIVE: In 2021, 37 members of a cohort of depleted uranium-exposed Gulf War I veterans were evaluated using a protocol tailored to accommodate COVID-19 safety practices on a telehealth platform. METHODS: Individual elements of the legacy protocol were reviewed for urgency and feasibility of inclusion in a modified, telehealth platform. RESULTS: The redesigned protocol included a participant readiness for telehealth assessment, nurse and physician telehealth visits, collection of usual health questionnaires, and urine collections for exposure monitoring for uranium and other fragment-related metal measures. CONCLUSIONS: Despite some limitations in scope, the telehealth platform permitted a visual "visit" with surveillance participants who expressed a high comfort level with the format. The telehealth platform has apparent utility for occupational surveillance and should be explored as a standard approach for surveillance outside of public health emergencies.

The Healthcare Sector Employer's Duty of Care: Implications for Worker Well-Being.

Pandemic diseases of this century have differentially targeted healthcare workers globally. These infections include Severe Acute Respiratory Syndrome SARS, the Middle East respiratory syndrome coronavirus Middle East respiratory syndrome coronavirus (MERS-CoV) and Ebola. The COVID-19 pandemic has continued this pattern, putting healthcare workers at extreme risk. Just as healthcare workers have historically been committed to the service of their patients, providing needed care, termed their "duty of care", so too do healthcare employers have a similar ethical duty to provide care toward their employees arising from historical common law requirements. This paper reports on results of a narrative review performed to assess COVID-19 exposure and disease development in healthcare workers as a function of employer duty of care program elements adopted in the workplace. Significant duty of care deficiencies reported early in the pandemic most commonly involved lack of personal protective equipment (PPE) availability. Beyond worker safety, we also provide evidence that an additional benefit of employer duty of care actions is a greater sense of employee well-being, thus aiding in the prevention of healthcare worker burnout.

Surveillance of Depleted Uranium-exposed Gulf War Veterans: More Evidence for Bone Effects.

ABSTRACT: Gulf War I veterans who were victims of depleted uranium (DU) "friendly-fire" incidents have undergone longitudinal health surveillance since 1994. During the spring of 2019, 36 members of the cohort were evaluated with a monitoring protocol including exposure assessment for total and isotopic uranium concentrations in urine and a comprehensive review of health outcomes, including measures of bone metabolism and bone mineral density (BMD) determination. Elevated urine U concentrations were observed in cohort members with retained depleted uranium (DU) shrapnel fragments. In addition, a measure of bone resorption, N-telopeptide, showed a statistically significant increase in those in the high DU subgroup, a finding consistent with a statistically significant decrease in bone mass also observed in this high DU subgroup compared to the low DU subgroup. After more than 25 y since first exposure to DU, an aging cohort of military veterans continues to show few U-related health effects in known target organs of U toxicity. The new finding of impaired BMD in the high DU subgroup has now been detected in two consecutive surveillance visits. While this is a biologically plausible uranium effect, it is not reflected in other measures of bone metabolism in the full cohort, which have largely been within normal limits. However, ongoing accrual of the U burden from fragment absorption over time and the effect of aging further impairing BMD suggest the need for future surveillance assessments of this cohort.

COVID-19 and Essential Workers: A Narrative Review of Health Outcomes and Moral Injury.

The COVID-19 pandemic has introduced a number of added obstacles to safe employment for already-challenged essential workers. Essential workers not employed in the health sector generally include racially diverse, low-wage workers whose jobs require close interaction with the public and/or close proximity to their coworkers, placing them at increased risk of infection. A narrative review facilitated the analyses of health outcome data in these workers and contributing factors to illness related to limited workplace protections and a lack of organizational support. Findings suggest that this already marginalized population may also be at increased risk of "moral injury" due to specific work-related factors, such as limited personal protective equipment (PPE) and the failure of the employer, as the safety and health "duty holder," to protect workers. Evidence suggests that ethical and, in some cases, legally required safety protections benefit not only the individual worker, but an employer's enterprise and the larger community which can retain access to resilient, essential services.

Surveillance results and bone effects in the Gulf War depleted uranium-exposed cohort.

A small group of Gulf War I veterans wounded in depleted uranium (DU) friendly-fire incidents have been monitored in a clinical surveillance program since 1993. During the spring of 2017, 42 members of the cohort were evaluated with a protocol which includes exposure monitoring for total and isotopic uranium concentrations in urine and a comprehensive assessment of health outcomes including measures of bone metabolism, and for participants >50 years, bone mineral density (BMD) determination. Elevated urine U concentrations were observed in cohort members with retained DU shrapnel fragments. Only the mean serum estradiol concentration, a marker of bone metabolism, was found to be significantly different for lower-vs- higher urine U (uU) cohort sub-groups. For the first time, a significant deficit in BMD was observed in the over age 50, high uU sub-group. After more than 25 years since first exposure to DU, an aging cohort of military veterans continues to exhibit few U-related adverse health effects in known target organs of U toxicity. The new finding of reduced BMD in older cohort members, while biologically plausible, was not suggested by other measures of bone metabolism in the full (all ages) cohort, as these were predominantly within normal limits over time. Only estradiol was recently found to display a difference as a function of uU grouping. As BMD is further impacted by aging and the U-burden from fragment absorption accrues in this cohort, a U effect may be clarified in future surveillance visits.

Impulse oscillometry measurement of distal airways obstruction in depleted uranium-exposed Gulf War veterans.

INTRODUCTION: A cohort of Gulf War I veterans who sustained exposure to depleted uranium undergoes biennial surveillance for potential uranium-related health effects. We performed impulse oscillometry and hypothesized that veterans with higher uranium body burdens would have more obstructive abnormalities than those with lower burdens. METHODS: We compared pulmonary function of veterans in high versus low urine uranium groups by evaluating spirometry and oscillometry values. RESULTS: Overall mean spirometry and oscillometry resistance values fell within the normal ranges. There were no significant differences between the high and low uranium groups for any parameters. However, more veterans were classified as having obstruction by oscillometry (42%) than spirometry (8%). CONCLUSIONS: While oscillometry identified more veterans as obstructed, obstruction was not uranium-related. However, the added sensitivity of this method implies a benefit in wider surveillance of exposed cohorts and holds promise in identifying abnormalities in areas of the lung historically described as silent.

Tutoring for Success: Empowering Graduate Nurses After Failure on the NCLEX-RN.

BACKGROUND: Failure on the National Council Licensure Examination for Registered Nurses (NCLEX-RN) is a devastating experience. Most research related to NCLEX-RN is focused on predicting and preventing failure. Despite these efforts, more than 20,000 nursing school graduates experience failure on the NCLEX-RN each year, and there is a paucity of literature regarding remediation after failure. METHOD: The aim of this article is to describe an individualized tutoring approach centered on establishing a trusting relationship and incorporating two core strategies for remediation: the nugget method, and a six-step strategy for question analysis. RESULTS: This individualized tutoring method has been used by three nursing faculty with a 95% success rate on an NCLEX retake attempt. CONCLUSION: Further research is needed to identify the elements of this tutoring method that influence success. [J Nurs Educ. 2017;56(12):758-761.].

Metal Exposure in Veterans With Embedded Fragments From War-Related Injuries: Early Findings From Surveillance Efforts.

OBJECTIVE: To characterize systemic metal exposures from retained fragments in a cohort of war-injured US Veterans enrolled in the Department of Veterans Affairs' Embedded Fragment Registry. METHODS: Five hundred seventy nine registry-enrolled Veterans submitted an exposure questionnaire and urine sample for analyses of 14 metals often found in fragments. Urine metal results were compared with reference values of unexposed populations to identify elevations. RESULTS: 55% of Veterans had normal urine metal values. When observed, tungsten and zinc were the metals most frequently elevated, followed by cobalt; however, cobalt levels were not associated with a fragment source, but with surgical implants present. CONCLUSIONS: Though most metal elevations observed are not significantly outside the normal range, on-going accrual of metal burdens in these Veterans over time recommends continued surveillance which may inform future medical management.

The U.S. Department of Veterans' Affairs depleted uranium exposed cohort at 25 Years: Longitudinal surveillance results.

BACKGROUND: A small group of Gulf War I veterans wounded in depleted uranium (DU) friendly-fire incidents have been monitored for health changes in a clinical surveillance program at the Veterans Affairs Medical Center, Baltimore since 1994. METHODS: During the spring of 2015, an in-patient clinical surveillance protocol was performed on 36 members of the cohort, including exposure monitoring for total and isotopic uranium concentrations in urine and a comprehensive assessment of health outcomes. RESULTS: On-going mobilization of U from embedded fragments is evidenced by elevated urine U concentrations. The DU isotopic signature is observed principally in participants possessing embedded fragments. Those with only an inhalation exposure have lower urine U concentration and a natural isotopic signature. CONCLUSIONS: At 25 years since first exposure to DU, an aging cohort of military veterans continues to show no U-related health effects in known target organs of U toxicity. As U body burden continues to accrue from in-situ mobilization from metal fragment depots, and increases with exposure duration, critical tissue-specific U concentration thresholds may be reached, thus recommending on-going surveillance of this veteran cohort.

Mobilization of Metal From Retained Embedded Fragments in a Blast-Injured Iraq War Veteran.

A frequent comorbidity of traumatic injury due to a blast or explosion, commonly reported in Iraq and Afghanistan veterans, is that of retained embedded fragments typically of unknown content. Because of concerns over both local and systemic health effects related to both the physical presence of and mobilization of materials from embedded fragments, the Department of Veterans Affairs established a surveillance program for this group of veterans. We present here the case of a surveillance-enrolled veteran who submitted: (1) three surgically removed fragments for content analyses, (2) tissue adhered to the fragments for histology and metal concentration evaluation, and (3) pre- and postfragment removal urine samples to assess concentrations of various metals often found in fragments. Results indicate that removed fragments were aluminum-copper alloys. Surrounding tissue analyses revealed elevated concentrations of these metals and evidence of chronic inflammation, but no neoplastic changes. Urine aluminum concentrations, initially elevated compared to normal population values, decreased significantly after fragment removal, illustrating the utility of urine biomonitoring to provide insight into fragment composition. A medical surveillance program integrating fragment composition data, tissue analyses, and repeat urine biomonitoring can help inform the patient-specific medical management of both the local and systemic effects of retained metal fragments.

Biologic monitoring and surveillance results for the department of veterans affairs' depleted uranium cohort: Lessons learned from sustained exposure over two decades.

BACKGROUND: A small group of Gulf War I veterans wounded in depleted uranium (DU) friendly fire incidents have been monitored in a clinical surveillance program at the Veterans Affairs Medical Center, Baltimore since 1994. METHODS: An in-patient clinical surveillance protocol was performed on 35 members of the cohort, including exposure monitoring for total and isotopic uranium concentrations in urine and a comprehensive assessment of health outcomes. RESULTS: Although urine U concentrations continue to be elevated in this group, illustrating on-going in situ mobilization of U from embedded fragments, no consistent U-related health effects have been observed. CONCLUSIONS: Now more than 20 years since first exposure to DU, an aging cohort of military veterans continues to show no U-related health effects in known target organs of U toxicity. As tissue concentrations continue to accrue with exposure duration, critical tissue-specific U concentration thresholds may be reached, thus recommending on-going surveillance of this veteran cohort.

Regulatory, institutional, and market-based approaches towards achieving comprehensive chemical policy reform.

The purpose of this article is to inform nurses and other health care professionals about the nexus between the environment and health and present approaches in which they can be involved so as to support comprehensive reform of chemicals management in the United States. It discusses the health impact of hazardous chemicals and the environmental regulatory failures within the U.S. to protect the public. It also reports on international chemical management initiatives and key elements of chemical policy reform that can guide the U.S. regulatory, market-based, and institutional-based approaches to a comprehensive, chemical policy reform. The role of nursing in advocating for these reforms will be presented.

Collection and use of exposure data from human milk biomonitoring in the United States.

Human milk is a unique biological matrix that can be used to estimate exposures in both the mother and the breastfed infant. In addition, the presence of environmental chemicals in human milk may act as a sentinel for exposures to a broader population. Several factors play a role in determining the quantity of chemicals transferred to milk and, subsequently, to the breastfeeding infant, including maternal, infant, and chemical characteristics. Exposure to certain environmental chemicals during critical periods can disrupt normal infant development, yet few data exist to quantify the hazards posed by environmental chemicals in human milk. Chemicals measured in human milk may also provide insights to agents suspect in altering breast development and breast-related disease risk. Carefully designed exposure assessment and toxicokinetic studies are needed to elucidate mechanisms and establish relationships between human milk and other biologic matrices. Data from human milk biomonitoring studies can be used to inform and validate models that integrate information about chemical properties, human metabolism, and biomarker concentrations. Additional research is needed to determine the degree to which environmental chemicals enter, are present in, and are excreted from human milk, their impact on the host (mother), and the extent of their bioavailability to breastfeeding infants. This article describes how the collection and use of exposure data from human milk biomonitoring in the United States can be designed to inform future research and policy.
