RESUMEN

BACKGROUND: Excessive heat stress led to more than 400 deaths in the United States from 2011 to 2021. Common methods for heat injury prevention revolve around measurements of the environment and fail to account for the unique individual response to stressors. METHODS: An observational approach was utilized with nine helicopter-based emergency medical services personnel during emergency flights to compare core temperature readings obtained from an ingestible temperature monitoring pill and the estimated core temperature reading of the Slate Safety Band V2 wearable device. Comparison of data was conducted within Microsoft Excel programming to determine the mean square error (MSE), root mean square error (RMSE), mean absolute error (MAE), mean biased error (MBE), and Bland-Altman plot development. FINDINGS: A significant bias (t = 17.58, p < .001) toward the Slate Safety device reading higher with an average difference of -0.48°C (-0.86°F) was found, meaning the average temperature reading is 0.48°C (-0.86°F) higher with the Slate Safety device. A significant correlation of .26 (p < .001) was noted between the ingestible pill and the wearable device with a 95% confidence interval of 0.23 to 0.29. Aggregate core temperature data demonstrated an MSE of 0.43, an RMSE of 0.65, an MAE of 0.54, and an MBE of -0.48. CONCLUSIONS/APPLICATION TO PRACTICE: The ability to monitor the physiological parameters of a worker remotely adds safety tools relative to the risks of heat stress. The slightly higher reading associated with the Slate Safety wearable device provides an added safety margin to protect our workers.

RESUMEN

BACKGROUND: The current state of nursing education is concerning, with nearly two-thirds of the American Association of Colleges of Nursing (AACN) and Commission of Collegiate Nursing Education (CCNE) -accredited universities reporting that their nursing graduates are ill-prepared to care for the LGBTQIA+ community (Eickhoff, 2021). This lack of training is alarming, given the ongoing reports of LGBTQIA+ healthcare discrimination and the insufficient knowledge of nursing faculty to guide future nurses in caring for this patient population (Hughes et al., 2022). AIM: Our study sought to address this gap by developing and assessing the effectiveness of an LGBTQIA+ inclusivity training module for Baccalaureate nursing students. DESIGN: We employed a quasi-experimental pretest-posttest design, evaluating nursing students' knowledge and attitudes before and after the LGBTQIA+ inclusivity training. SETTING: The study was conducted in a four-year baccalaureate nursing program in the Southern United States. PARTICIPANTS: Junior-level baccalaureate nursing students. METHODS: Using a pre-test post-test method, we collected data that included the Gay Affirmative Practice Scale, an LGBTQIA+ knowledge assessment, and a computer-based LGBTQIA+ inclusivity training module. RESULTS: N = 30 students consented and completed all necessary study components. The findings revealed significant improvements in pre-test and post-test GAP and knowledge assessment scores following the LGBTQIA+ Inclusivity Training for baccalaureate nursing students. CONCLUSIONS: The results of our study underscore the effectiveness of an LGBTQIA+ computer-based simulation experience for baccalaureate nursing students, marking a significant step towards improving LGBTQIA+ healthcare inclusivity in nursing education.

RESUMEN

BACKGROUND: Simulation-based learning experiences allow undergraduate nursing students to develop competence and confidence through deliberate practice with immediate feedback on the learner's performance through debriefing. With the transition to competency-based nursing education, nursing faculty need more guidance in implementing competency-based evaluations in the simulation setting. PURPOSE: This Delphi study aims to inform the future development of a competency-based tool - SimComp - based on the American Association of Colleges of Nursing (AACN) Essentials. METHODS: A Delphi framework was used to recruit expert nursing faculty to complete the surveys via an online platform. Data analysis occurred through open-ended questions and quantitative methods to ensure that the responses from expert panelists were used to form the results. RESULTS: After four rounds of this Delphi study, a consensus was achieved on 111 appropriate items for assessing competence in the simulation-based learning environment. CONCLUSION: While further research is warranted, this study provides insight for nursing institutions considering implementing or increasing the use of simulation within their program for competency-based evaluations.

RESUMEN

RATIONALE AND OBJECTIVES: To assess whether academic radiology departments and residency programs with efforts toward supporting and augmenting Diversity, Equity, and Inclusion (DEI) are associated with a higher proportion of residents from diverse backgrounds. MATERIALS AND METHODS: Program Directors within the Radiology Residency Education Research Alliance were surveyed to gather information about program characteristics, incorporation of diversity in resident recruitment, the sponsoring department's commitment to efforts at expanding diversity, and a summary of their current and past residents, staff and faculty members (academic years 2020 and 2023) with respect to a list of diversity characteristics. RESULTS: Survey response rate was 51 %. Sixty-three percent (15/24) of participating programs have departmental committees dedicated to DEI work; 46 % (11/24) of programs' departments have a Vice Chair for DEI. Sixty percent (15/24) of programs use their social media accounts to advertise their DEI programming efforts. Ninety-six percent (23/24) of programs participating in the survey use diversity factors to select candidates for their program. Women Leadership was associated with above-median diversity of residents and faculty. CONCLUSION: This study of radiology residency programs encourages a more prominent role for women in leadership positions within academic radiology departments to drive diversity and inclusion efforts.

RESUMEN

INTRODUCTION: Disparities in clinical trials (CTs) enrollment perpetuate inequities in treatment access and outcomes, but there is a paucity of Canadian data. The objective of this study was to examine disparities in cancer CT enrollment at a large Canadian comprehensive cancer center. METHODS: Retrospective study of CT enrollment among new patient consultations from 2006 to 2019, with follow-up to 2021 (N = 154,880), with the primary outcome of enrollment as a binary variable. Factors associated with CT enrollment were evaluated using multivariable Bayesian hierarchical logistic regression with random effects for most responsible physician (MRP) and geography, adjusted for patient characteristics (sex, age, language, geography, and primary care provider [PCP]), area-level marginalization (residential instability, material deprivation, dependency, and ethnic concentration), disease (cancer site and stage), and MRP (department, sex, language, and training). A sensitivity analysis of the cumulative incidence of enrollment was conducted to account for differences in disease type and follow-up length. RESULTS: CT enrollment was 11.2% overall, with a 15-year cumulative incidence of 18%. Lower odds of enrollment were observed in patients who were female (adjusted odds ratio [AOR], 0.82; 95% confidence interval [CI], 0.78-0.86), ≥65 years (AOR vs. <40, 0.61; 95% CI, 0.56-0.66), non-English speakers (0.72; 95% CI, 0.67-0.77), living ≥250 km away (AOR vs. <15 km, 0.71; 95% CI, 0.62-0.80), and without a PCP. Disease characteristics accounted for the largest proportion of observed variation (20.8%), with significantly greater odds of enrollment in patients with genitourinary cancers and late-stage disease. CONCLUSION: Significant sociodemographic disparities were observed, suggesting the need for targeted strategies to increase diversity in access to cancer CTs in Canada.

RESUMEN

OBJECTIVE: The primary objective is to assess factors associated with treatment related high grade (CTCAE grade ≥ 3) adverse event (AE) reporting among participants in gynecologic oncology clinical trials. METHODS: All AEs recorded in the Princess Margaret Clinical Trial adverse event database between 01/2016 and 12/2018 were evaluated. Gynecologic oncology clinical trials assessing systemic therapy were included. Inferential statistics on risk factors of related grade ≥ 3 adverse event reporting and GEE logistic models with Odds Ratios (OR) were performed. Multivariable analysis adjusting for age, clinical trial phase, sponsor, and therapy type. RESULTS: The gynecology cancer clinical trials accrued 317 unique patients (359 nested on trials) in 42 systemic therapy trials. In the period, 17,175 related AEs were reported in the gynecological cancer trials, 7.4% were grade ≥ 3. On multivariable analysis, no odds differences of grade ≥ 3 related AEs were detected according to study phase. Patients in immunotherapy clinical trials had lower odds of related grade ≥ 3 AEs than patients on targeted or other therapy (adjusted OR [aOR] 0.43; 95% CI 0.24-0.75). There was greater odds of related grade ≥ 3 AEs in clinical trials assessing combination vs single therapeutics (aOR 2.26, 95% CI 1.34-3.80). Patients aged ≥65 (aOR 1.77; 95% CI 1.08-2.89) had greater odds of related grade ≥ 3 AEs than patients aged 50 to 65 years. When compared to other disease sites, the odds of having a grade  ≥ 3 related AE reported in gynecology clinical trials was no different. CONCLUSIONS: In this cohort, factors influencing the odds of related grade ≥ 3 AE reporting in gynecologic trials included type of therapy and age. The study phase did not correlate with odds of high-grade AE reporting.

RESUMEN

The need for clinical placements for undergraduate nursing programs heightened during the COVID-19 pandemic as nursing schools across the country faced restrictions with the high-risk geriatric client population. Nursing students experienced increased anxiety levels, decreased learning opportunities, and uncertainties about the decision to enter the workforce as healthcare professionals. In turn, this amplified the need for faculty support and feedback imperative for student success. One method for mitigating the gap between didactic content and clinical placement is using simulation-based learning experiences. The purpose of this observational study was to examine the impact of a newly developed home health geriatric simulation on student satisfaction and self-confidence in learning among 133 senior-level Baccalaureate nursing students from a large public university. Study measures included the National League of Nursing's Self-Confidence in Learning Scale (SCLS) and Simulation Design Scale (SDS). The primary outcome was satisfaction and self-confidence in learning. Higher SDS component scores were significantly correlated with higher SCLS scores (all p = <.0001), indicating that high satisfaction among Baccalaureate nursing students in simulation design relates to increased satisfaction and self-confidence in learning. Study findings support using standardized geriatric simulation scenarios to prepare students to communicate and care for older adults.

RESUMEN

OBJECTIVES: Given the dynamic and high-stress environment of nursing education today, the need arose for the development and implementation of a novel peer mentoring program to support undergraduate nursing students. Peer mentoring refers to a network of support in which a more skilled or experienced person serves as a role model for a less skilled person for professional development and personal growth. Peer mentoring provides a support system that encourages self-confidence and increases self-worth for both the mentee and the mentor. The undergraduate student peer mentoring program in a large, Southeastern United States, university-based, 4-year school of nursing was created in response to a desire for more support conveyed by upper-level nursing students. METHODS: A model was developed whereby each incoming nursing student (Semester 1) would be paired with a senior nursing student (Semesters 3, 4, or 5). This mentoring dyad was then assigned to a faculty mentor who ensured that the mentoring relationship was functioning in accordance with established guidelines and provided support to both the student mentee and the student mentor. RESULTS: The first cohort was comprised of 20 mentoring dyads. Subsequent cohorts have ranged from 20 to 45 mentoring dyads. To date, over 300 nursing students have participated in the undergraduate peer mentoring program. Based on feedback from student evaluation surveys, both mentors and mentees appreciate and find value in the program. Approximately 93% of student mentors indicated that they would have appreciated such a program when they were first semester nursing students. CONCLUSION: Some of the challenges of navigating nursing programs are not related to lack of academic aptitude. Rather, other challenges, including lack of social support and soft skills needed to successfully complete the first and second semesters of nursing school. These are critical challenges that a peer mentor could help to meet.

RESUMEN

BACKGROUND: With the increase in concern for deaths and illness related to the increase in temperature globally, there is a growing need for real-time monitoring of workers for heat stress indicators. The purpose of this study was to determine the usability of the Slate Safety (SS) wearable physiological monitoring system. METHODS: Twenty nurses performed a common task in a moderate or hot environment while wearing the SS device, the Polar 10 monitor, and having taken the e-Celsius ingestible pill. Data from each device was compared for correlation and accuracy. RESULTS: High correlation was determined between the SS wearable device and the Polar 10 system (0.926) and the ingestible pill (0.595). The SS was comfortable to wear and easily monitored multiple participants from a distance. CONCLUSIONS: The Slate Safety wearable device demonstrated accuracy in measuring core temperature and heart rate while not restricting the motion of the worker, and provided a remote monitoring platform for physiological parameters.

RESUMEN

INTRODUCTION: Clinical judgment is imperative for the emergency nurse caring for the acutely ill patients often seen in the emergency department. Without optimal clinical judgment in the emergency department, patients are at risk of medical errors and a failure to rescue. METHODS: A descriptive observational approach using the Lasater Clinical Judgment Rubric evaluated nurses during a task that required recognition of clinical signs of deterioration and appropriate clinical care for simulated patients. RESULTS: A total of 18 practicing emergency nurses completed only 44.6% of the patient assessments leading to low levels of clinical judgment throughout the simulation. Nurses expressed 4 levels of clinical judgment: exemplary (n = 1), accomplishing (n = 6), developing (n = 9), and beginning (n = 2). On average, nurses completed 69% of required tasks. DISCUSSION: Assessments were completed less than half the time, demonstrating a breakdown in the noticing phase of clinical judgment. The nurses shifted to task completion focus with minimal use of clinical judgment. As the nurses remained task oriented, several medication and medical errors were noted while caring for the simulated patients. Experience and education did not influence observed clinical judgment among the participants. Given the extreme demands placed on the emergency nurse, it cannot be assumed that nurses have developed or can use clinical judgment when caring for their patients. Time and training targeting clinical judgment are essential for emergency nurse development.

RESUMEN

OBJECTIVE: To identify factors associated with radioactive iodine (RAI)-acquired nasolacrimal duct obstruction (NLDO). METHODS: Retrospective chart review and telephone surveys of patients who received RAI therapy for thyroid carcinoma at an academic institution were conducted. Telephone surveys were used to screen for post-RAI NLDO diagnoses. Databases were reviewed for documented NLDO, demographics, RAI dose, total number of RAI treatments, and sialadenitis. Routine post-RAI whole-body scintigraphy (WBS) images were analyzed for the presence or absence of 131I sodium iodide (I-131) in the nasolacrimal duct. Intranasal I-131 activity was graded as none, low, moderate, and high; those with moderate or high activity were considered to have "increased" activity. Logistic and ordinal logistic regression models were used to evaluate the associations with NLDO while adjusting for I-131 dose. RESULTS: Of the 209 patients who completed the survey, 15 (7%) had NLDO diagnoses. Increased intranasal I-131 activity on WBS, presence of nasolacrimal I-131 WBS activity, presence of documented post-RAI sialadenitis, and history of >1 RAI treatment were associated with the development of NLDO from univariate analyses (P ≤ .013). After adjusting for the administered dose of I-131, the presence of sialadenitis and nasolacrimal I-131 activity on WBS were the remaining 2 factors significantly associated with NLDO development (P < .001 and P = .01, respectively). CONCLUSIONS: The presence of sialadenitis and nasolacrimal I-131 activity on WBS are I-131 dose-independent correlative factors for RAI-associated NLDO. Patients with these characteristics should be counseled on their increased risk of NLDO after RAI therapy for thyroid carcinoma.

RESUMEN

Chronic diseases in growing children, such as autoimmune disorders, obesity, and cancer, are hallmarked by musculoskeletal growth disturbances and osteoporosis. Many of the skeletal changes in these children are thought to be secondary to chronic inflammation. Recent studies have likewise suggested that changes in coagulation and fibrinolysis may contribute to musculoskeletal growth disturbances. In prior work, we demonstrated that mice deficient in plasminogen, the principal protease of degrading and clearing fibrin matrices, suffer from inflammation-driven systemic osteoporosis and that elimination of fibrinogen resulted in normalization of IL-6 levels and complete rescue of the skeletal phenotype. Given the intimate link between coagulation, fibrinolysis, and inflammation, here we determined if persistent fibrin deposition, elevated IL-6, or both contribute to early skeletal aging and physeal disruption in chronic inflammatory conditions. Skeletal growth as well as bone quality, physeal development, and vascularity were analyzed in C57BL6/J mice with plasminogen deficiency with and without deficiencies of either fibrinogen or IL-6. Elimination of fibrinogen, but not IL-6, rescued the skeletal phenotype and growth disturbances in this model of chronic disease. Furthermore, the skeletal phenotypes directly correlated with both systemic and local vascular changes in the skeletal environment. In conclusion, these results suggest that fibrinolysis through plasmin is essential for skeletal growth and maintenance, and is multifactorial by limiting inflammation and preserving vasculature.

RESUMEN

Severely injured patients are beleaguered by complications during convalescence, such as dysregulated biomineralization. Paradoxically, severely injured patients experience the loss of bone (osteoporosis), resulting in diminished skeletal integrity and increased risk of fragility fractures; yet they also accrue mineralization in soft tissues, resulting in complications such as heterotopic ossification (HO). The pathophysiology leading to dysregulated biomineralization in severely injured patients is not well defined. It has been postulated that these pathologies are linked, such that mineralization is "transferred" from the bone to soft tissue compartments. The goal of this study was to determine if severe injury-induced osteoporosis and soft tissue calcification are temporally coincident following injury. Using a murine model of combined burn and skeletal muscle injury to model severe injury, it was determined that mice developed significant progressive bone loss, detectable as early as 3 days post injury, and marked soft tissue mineralization by 7 days after injury. The observed temporal concordance between the development of severe injury-induced osteoporosis and soft tissue mineralization indicates the plausibility that these complications share a common pathophysiology, though further experiments are required.

RESUMEN

CASE: A patient presented with a traumatic posterior wall fracture and small femoral head fracture. He initially underwent open reduction and internal fixation to treat the posterior wall fracture. The femoral head fracture was left alone because of its small size and lack of joint incongruity. At 1 year postoperatively, the patient reported pain due to malunion of the femoral head fragment, which was treated arthroscopically. Treatment resulted in significant pain relief sustained at the 6-year follow-up. CONCLUSION: Symptomatic femoral head fractures malunited to the femoral neck are rare complications. Arthroscopy may offer a viable treatment approach for select patients with this condition.

RESUMEN

Background: When phenotypic characters are described in the literature, they may be constrained or clarified with additional information such as the location or degree of expression, these terms are called "modifiers". With effort underway to convert narrative character descriptions to computable data, ontologies for such modifiers are needed. Such ontologies can also be used to guide term usage in future publications. Spatial and method modifiers are the subjects of ontologies that already have been developed or are under development. In this work, frequency (e.g., rarely, usually), certainty (e.g., probably, definitely), degree (e.g., slightly, extremely), and coverage modifiers (e.g., sparsely, entirely) are collected, reviewed, and used to create two modifier ontologies with different design considerations. The basic goal is to express the sequential relationships within a type of modifiers, for example, usually is more frequent than rarely, in order to allow data annotated with ontology terms to be classified accordingly. Method: Two designs are proposed for the ontology, both using the list pattern: a closed ordered list (i.e., five-bin design) and an open ordered list design. The five-bin design puts the modifier terms into a set of 5 fixed bins with interval object properties, for example, one_level_more/less_frequently_than, where new terms can only be added as synonyms to existing classes. The open list approach starts with 5 bins, but supports the extensibility of the list via ordinal properties, for example, more/less_frequently_than, allowing new terms to be inserted as a new class anywhere in the list. The consequences of the different design decisions are discussed in the paper. CharaParser was used to extract modifiers from plant, ant, and other taxonomic descriptions. After a manual screening, 130 modifier words were selected as the candidate terms for the modifier ontologies. Four curators/experts (three biologists and one information scientist specialized in biosemantics) reviewed and categorized the terms into 20 bins using the Ontology Term Organizer (OTO) (http://biosemantics.arizona.edu/OTO). Inter-curator variations were reviewed and expressed in the final ontologies. Results: Frequency, certainty, degree, and coverage terms with complete agreement among all curators were used as class labels or exact synonyms. Terms with different interpretations were either excluded or included using "broader synonym" or "not recommended" annotation properties. These annotations explicitly allow for the user to be aware of the semantic ambiguity associated with the terms and whether they should be used with caution or avoided. Expert categorization results showed that 16 out of 20 bins contained terms with full agreements, suggesting differentiating the modifiers into 5 levels/bins balances the need to differentiate modifiers and the need for the ontology to reflect user consensus. Two ontologies, developed using the Protege ontology editor, are made available as OWL files and can be downloaded from https://github.com/biosemantics/ontologies. Contribution: We built the first two modifier ontologies following a consensus-based approach with terms commonly used in taxonomic literature. The five-bin ontology has been used in the Explorer of Taxon Concepts web toolkit to compute the similarity between characters extracted from literature to facilitate taxon concepts alignments. The two ontologies will also be used in an ontology-informed authoring tool for taxonomists to facilitate consistency in modifier term usage.
