RESUMEN

The role of parathyroid hormone (PTH)-related protein (PTHrP) in breast cancer remains controversial, with reports of PTHrP inhibiting or promoting primary tumor growth in preclinical studies. Here, we provide insight into these conflicting findings by assessing the role of specific biological domains of PTHrP in tumor progression through stable expression of PTHrP (-36-139aa) or truncated forms with deletion of the nuclear localization sequence (NLS) alone or in combination with the C-terminus. Although the full-length PTHrP molecule (-36-139aa) did not alter tumorigenesis, PTHrP lacking the NLS alone accelerated primary tumor growth by downregulating p27, while PTHrP lacking the NLS and C-terminus repressed tumor growth through p27 induction driven by the tumor suppressor leukemia inhibitory factor receptor (LIFR). Induction of p27 by PTHrP lacking the NLS and C-terminus persisted in bone disseminated cells, but did not prevent metastatic outgrowth, in contrast to the primary tumor site. These data suggest that the PTHrP NLS functions as a tumor suppressor, while the PTHrP C-terminus may act as an oncogenic switch to promote tumor progression through differential regulation of p27 signaling.

RESUMEN

BACKGROUND: Most pediatric patients present to general emergency departments, yet maintaining pediatric equipment, skilled staff, and resources remains a challenge for many hospitals. Pediatric readiness assessment is now a requirement for trauma center verification. OBJECTIVE: This study aims to assess the impact of a quality improvement initiative to improve emergency department pediatric readiness. METHODS: A pre- and poststudy design was used to evaluate a quality improvement initiative to improve the National Pediatric Readiness assessment survey results conducted at a Southwestern United States adult Level I trauma center from September 2022 to April 2023. The multicomponent initiative included implementing a pediatric emergency care coordinator, pediatric-specific policies and procedures, identifying pediatric-specific quality and performance indicators, and educating pediatric-specific staff. Study inclusion criteria were all patients younger than 18 years who presented to the emergency department. The primary outcome measure was the improvement in the weighted Pediatric Readiness Score. Secondary outcomes were throughput, nursing documentation of vital signs, and pain scores. RESULTS: A total of N = 2,356 patients met inclusion, of which n = 1,158 (49.2%) were in the preintervention group and n = 1,198 (50.8%) postintervention group. The weighted Pediatric Readiness Score improved by 45.4%. Transfers to a pediatric hospital increased from 4.1% to 8.6% (p = .016). Blood pressure documentation improved slightly from 88.3% to 88.6%. Pain score documentation decreased from 83.9% to 63.1% (p = .008). Pain medication and administration improved from 19.8% to 26.7% (p = .046). CONCLUSION: We found that participation in the quality improvement initiative was associated with emergency department pediatric readiness improvements.

RESUMEN

INTRODUCTION: Nationwide shelter-in-place (SIP) orders during the pandemic have had long-lasting effects, including increased rates of domestic violence and interpersonal violence. Screening for violence varies by institution, which tool is used, and when. Given increases in burn and trauma admissions over the course of the pandemic, we sought to examine trends at our institution during this time period to better guide care and anticipate system-level effects. METHODS: We performed a retrospective cohort study of pediatric burn and adult burn and trauma patients at our level 1 trauma/burn center between March-May 2019 and March-May 2020. Home safety screening was performed by nursing staff using a 1-part screening questionnaire. Patients presenting before March 15, 2020, were defined as "pre-SIP; " between March 16-May 19, 2020, were "during SIP; " and those after May 19, 2020, were designated as "post-SIP." Descriptive and chi-square statistics were used. Demographic, injury patterns, and screening information were collected. RESULTS: Blunt trauma comprised 60% of injuries, followed by burns (30%) then penetrating injury (7%). Over the entire time period analyzed, 1822 patients had documented home safety screening; ∼2% of patients screened reported a safety concern pre-SIP, compared to 3% of patients during SIP. There were higher rates of burns and penetrating injury during SIP compared to other periods (P ≤ 0.0001). Home safety screening rates were 94%-95% pre- and during SIP, but dropped to 85% post-SIP (P < 0.0001). Home safety concerns were reported almost 2% of the time pre-SIP and 3% during SIP (P = 0.016). CONCLUSIONS: We noted an increase in trauma and burns during and after SIP orders, consistent with the experiences of other institutions. Implementation of a nurse-driven screening process demonstrated high compliance with appropriate referrals. The burden of burn and traumatic injury remains significant, highlighting a need for continued psychosocial screening and the provision of psychosocial support resources in the acute trauma setting.

RESUMEN

BACKGROUND: COVID-19 challenged U.S. trauma centers to grapple with demands for expanded services with finite resources while also experiencing a concurrent increase in violent injuries. OBJECTIVE: The purpose of this study was to describe the impact of COVID-19 on the roles and duties of U.S. hospital-based injury prevention professionals. METHODS: This descriptive cross-sectional survey study of hospital-based injury prevention professionals was conducted between June 2021 and August 2021. Participants were recruited from six organizational members of the national Trauma Prevention Coalition, including the American Trauma Society, Emergency Nurses Association, Injury Free Coalition for Kids, Safe States Alliance, Society for Trauma Nurses, and Trauma Center Association of America. Results were analyzed using descriptive and inferential statistics. RESULTS: A total of 216 participants affiliated with 227 trauma centers responded. The following changes were reported during 2020: change in injury prevention position (range = 31%-88%); change in duties (range = 92%-100%); and change to hospital-based injury prevention programs (range = 75%-100%). Sixty-one (43%) single-center participants with a registered nurse license were reassigned to clinical duties compared with six (10%) nonlicensed participants (OR = 5.6; 95% CI [1.96, 13.57]; p < .001). Injury prevention programs at adult-only and combined adult and pediatric trauma centers had higher odds of suspension than pediatric-only trauma centers (OR = 3.6; 95% CI [1.26, 10.65]; p < .017). CONCLUSION: The COVID-19 response exposed the persistent inequity and limited prioritization of injury prevention programming as a key deliverable for trauma centers.

RESUMEN

BACKGROUND: Video-based assessment and review are becoming increasingly common, and trauma video review (TVR) has been shown to be an effective educational, quality improvement, and research tool. Yet, trauma team perception of TVR remains incompletely understood. OBJECTIVE: We evaluated positive and negative perceptions of TVR across multiple team member groups. We hypothesized that members of the trauma team would find TVR educational and that anxiety would be low across all groups. METHODS: An anonymous electronic survey was provided to nurses, trainees, and faculty during weekly multidisciplinary trauma performance improvement conference following each TVR activity. Surveys assessed perception of performance improvement and anxiety or apprehension (Likert scale: 1 "strongly disagree" to 5 "strongly agree"). We report individual and normalized cumulative scores (average of responses for each positive [n = 6] and negative [n = 4] question stem). RESULTS: We analyzed 146 surveys over 8 months, with 100% completion rate. Respondents were trainees (58%), faculty (29%), and nurses (13%). Of the trainees, 73% were postgraduate year (PGY) 1-3 and 27% were PGY 4-9. Of all respondents, 84% had participated previously in a TVR conference. Respondents reported an improved perception of resuscitation education quality and personal leadership skills development. Participants found TVR to be more educational than punitive overall. Analysis of team member types showed lower scores for faculty for all positive stemmed questions. Trainees were more likely to agree with negative stemmed questions if they were a lower PGY, and nurses were least likely to agree with negative stemmed questions. CONCLUSIONS: TVR improves trauma resuscitation education in a conference setting, with trainees and nurses reporting the greatest benefit. Nurses were noted to be the least apprehensive about TVR.

RESUMEN

INTRODUCTION: Charge nurses (CNs) are shift leaders who manage resources and facilitate patient care, yet CNs in EDs receive minimal training, with implications for patient safety and emergency nursing practice. The purpose of the study was to describe the experiences of emergency nurses related to training, preparation, and function of the CN role. METHODS: An explanatory sequential mixed methods design using survey data (n = 2579) and focus group data (n = 49) from both CN and staff nurse perspectives. RESULTS: Participants reported minimal training for the CN role, with divergent understandings of role, required education and experience, the need for situational awareness, and the acceptability of the CN taking on other duties. CONCLUSIONS: The ED CN is critical to the safety of both nursing environment and patient care. Nurses in this pivotal role do not receive adequate leadership orientation or formal training in the key areas of nurse patient assignment, communication, and situational awareness. Formal training in nurse-patient assignment, communication, and situational awareness are critical to appropriate patient care and maintenance of interprofessional trust necessary for successful execution of the CN role. ED nurse managers should advocate for this training.

RESUMEN

PURPOSE OF REVIEW: Breast cancer frequently metastasizes to the bone and lung, but the ability to treat metastatic tumor cells remains a pressing clinical challenge. Histone deacetylases (HDACs) and histone acetyltransferases (HATs) have emerged as promising targets since these enzymes are aberrantly expressed in numerous cancers and regulate the expression of genes that drive tumorigenesis and metastasis. This review focuses on the abnormal expression of histone-modifying enzymes in cancers that have a high tropism for the bone and lung and explores the clinical use of histone deacetylase inhibitors for the treatment and prevention of metastasis to these sites. RECENT FINDINGS: Preclinical studies have demonstrated that the role for HDACs is highly dependent on tumor type and stage of disease progression. HDAC inhibitors can induce apoptosis, senescence, cell differentiation, and tumor dormancy genes and inhibit angiogenesis, making these promising therapeutics for the treatment of metastatic disease. HDAC inhibitors are already FDA approved for hematologic malignancies and are in clinical trials with standard-of-care chemotherapies and targeted agents for several solid tumors, including cases of metastatic disease. However, these drugs can negatively impact bone homeostasis. Although HDAC inhibitors are not currently administered for the treatment of bone and lung metastatic disease, preclinical studies have shown that these drugs can reduce distant metastasis by targeting molecular factors and signaling pathways that drive tumor cell dissemination to these sites. Thus, HDAC inhibitors in combination with bone protective therapies may be beneficial in the treatment of bone metastatic cancers.

RESUMEN

Many of the current accepted treatment practices provided to patients in the first critical hour after a traumatic injury, stroke, or cardiac arrest have not been rigorously tested in clinical research trials. The inability to obtain informed consent is often a barrier to research in emergency, time-sensitive situations in which the patient is not able to provide informed consent nor is their family member immediately available to provide consent on behalf of the patient. Planned emergency research, often with exception from informed consent, is a type of research study that involves a patient with a life-threatening medical condition that requires urgent interventions, wherein the current treatments may be unproven or suboptimal, and who, because of their current condition, is unable to provide informed consent. This article summarizes the necessary components for using exception from informed consent in planned emergency research. Understanding the research design, particularly research processes specific to time-critical emergency situations, will ensure that the care provided by stretcher-side emergency nurses will result in optimal patient outcomes and is an integral aspect of emergency nursing practice.

RESUMEN

OBJECTIVE: The Veracyte Afirma Gene Expression Classifier (GEC) has been the most widely used negative predictive value molecular classifier for indeterminate cytology thyroid nodules since January 2011. To improve the specificity and further reduce unnecessary thyroid surgeries, a second-generation assay (Afirma Genetic Sequence Classifier [GSC]) was released for clinical use in August 2017. We report 11 months of clinical outcomes experience with the GSC and compare them to our 6.5-year experience with the GEC. METHODS: We searched our practice registry for FNAB nodules with Afirma results from January 2011through June 2018. GEC versus GSC results were compared overall, in oncocytic and nononcocytic aspirates and by pathologic outcomes. RESULTS: GSC identified less indeterminate cytology nodules as suspicious (38.8%; 54/139) when compared to GEC (58.4%; 281/481). There was a decrease of in the percentage of oncocytic fine-needle aspiration thyroid biopsy (FNAB) subjects classified as suspicious in the GSC group, with 86 of 104 oncocytic indeterminates (82.7%) classified as suspicious by GEC and 12 of 34 (35.3%) classified as suspicious by GSC. The surgery rate in patients with oncocytic aspirates fell from 56% in the GEC group to 31% in the GSC-evaluated group (45%). Pathology analysis demonstrated a false-negative percentage for an incomplete surgical group of 9.5% for GEC and 1.2% for GSC. CONCLUSION: Our GSC data suggest that the GSC further reduces surgery in indeterminate thyroid nodules by improving the specificity of Afirma technology without compromising sensitivity. A primary determinant for this change is a significant improvement in the specificity of the Afirma GSC test in oncocytic FNAB aspirates. ABBREVIATIONS: FNAB = fine-needle aspiration biopsy; GEC = Gene Expression Classifier; GSC = Genetic Sequence Classifier.

RESUMEN

OBJECTIVE: Afirma Gene Expression Classifier® (Afirma GEC) molecular analysis (Veracyte, Inc, San Francisco, CA) is a negative predictive value test developed to reduce the number of thyroidectomies in thyroid nodule patients with indeterminate cytology. GEC technology has reportedly reduced unnecessary thyroid surgery, but few studies have examined Afirma GEC false-negative rates, since usually patients with GEC benign nodules do not undergo surgery for definitive diagnosis. Occasionally, Afirma GEC benign patients require removal of their thyroid nodules for other reasons; this work describes the incidence of malignancy and noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP) in this population. METHODS: We reviewed our community endocrine surgical practice database for patients who had undergone thyroid surgery from January 2011 through April 2017 despite benign Afirma GEC results. RESULTS: Afirma GEC testing was completed for 475 patients during the study period. Surgery was clinically indicated for other reasons in 42 of the 193 patients (22%) with Afirma GEC benign results. Malignancy or NIFTP in the targeted nodule was found in the final histologic evaluation of 14 of the 42 Afirma GEC benign surgical patients. The Afirma GEC false-negative percentage for our incomplete surgical group (FNP-ISG), defined as the surgically proven false negatives divided by the total Afirma GEC benign patients, was 7.3%. CONCLUSION: Our high surgical rate in Afirma GEC benign nodules reveals an FNP-ISG of 7.3% in our community endocrine surgical patient population; this value exceeds the 5.7% reported in the multicenter 2012 Afirma GEC validation study. ABBREVIATIONS: Afirma GEC = Afirma Gene Expression Classifier; FNA = fine-needle aspiration; FNP = false-negative percentage; FNP-ISG = false-negative percentage for an incomplete surgical group; NIFTP = noninvasive follicular thyroid neoplasms with papillary-like nuclear features.

RESUMEN

PROBLEM: Emergency medical care often necessitates placement of peripheral intravenous (PIV) catheters. When traditional methods for obtaining PIV access are not successful, ultrasound guidance is a rescue technique for peripheral vascular placement that improves the quality of patient care. METHODS: The aim of this training program was to develop a process where emergency nurses would be competent to perform ultrasound guided PIV to improve the quality of patient care delivered while reducing throughput time. Administrative program development required creating a nursing practice statement, procedure guideline, operational plan, and competency validation. A training program comprising both didactic and hands-on training was developed and provided by emergency medicine physicians with formal ultrasound fellowship training. RESULTS: In determining whether the training program was adequate in preparing the student to place an ultrasound-guided PIV, 92.9% of students "agreed" or "strongly agreed." In having confidence in their ability to obtain an ultrasound guided PIV catheter placement, 35.7% of respondents "agreed" and 64.3% "strongly agreed." In finding it difficult to be successful in achieving ultrasound guided PIV catheter placement, 71.4% of students "strongly disagreed" and 14.3% "disagreed." All students (100%) felt it was a feasible task to train nurses to successfully place ultrasound-guided PIV catheters and 71.4% of students strongly support continuing to provide this training program and competency validation. DISCUSSION: Establishment of an effective didactic and hands-on training program resulted in emergency department nurses becoming competent in placement of ultrasound guided PIV catheters to provide optimal patient care.

RESUMEN

Each year approximately 1 in 4 healthy older adults aged 65+ years and 1 in 2 aged 80+ years living in the community will fall. Fall-related injuries are the leading cause of death and disability and cost the United States approximately $31 billion annually. Currently, no repository of scene data exists that informs prevention programs regarding circumstances that contribute to older adult falls. This was a multicenter (4 sites: Kansas, Maryland, Oregon, and Texas) pilot study consisting of interviews of older (55+ years) patients who had been admitted to a trauma center with fall-related injuries. Questions included information regarding environment, behaviors, injuries, and demographics. Additional information was abstracted from patient medical record: comorbidities, medications, and discharge information. Data are presented descriptively. Forty-nine patients were interviewed: average age was 78 years; White (93.9%); female (53.1%); and most (63.3%) had fallen before. The most commonly reported fall factors and injuries included those occurring at home without agency services (65.0%), on hard flooring (51.1%), with laced shoes (44.2%), and with walkers (36.7%) and contained contusion/open wound of head (61.2%). Survey time was anecdotally estimated at 10-15 min. Preliminary data suggest that prevention efforts should emphasize on educating older adults to focus on ambulation, body position, and use of assistive devices in their daily activities. The development of a systematic and organized registry that documents scene data would inform public health agencies to develop fall prevention programs that promote older adult safety. Furthermore, it would provide a large sample size to test factor associations with injury severity.

RESUMEN

Nearly half of all states have legalized medical marijuana or recreational-use marijuana. As more states move toward legalization, the effects on injured patients must be evaluated. This study sought to determine effects of cannabis positivity at the time of severe injury on hospital outcomes compared with individuals negative for illicit substances and those who were users of other illicit substances. A Level I trauma center performed a retrospective chart review covering subjects over a 2-year period with toxicology performed and an Injury Severity Score (ISS) of more than 16. These individuals were divided into the negative and positive toxicology groups, further divided into the marijuana-only, other drugs-only, and mixed-use groups. Differences in presenting characteristics, hospital length of stay, intensive care unit (ICU) stays, ventilator days, and death were compared. A total of 8,441 subjects presented during the study period; 2,134 (25%) of these had toxicology performed; 843 (40%) had an ISS of more than 16, with 347 having negative tests (NEG); 70 (8.3%) substance users tested positive only for marijuana (MO), 323 (38.3%) for other drugs-only, excluding marijuana (OD), and 103 (12.2%) subjects showed positivity for mixed-use (MU). The ISS was similar for all groups. No differences were identified in Glasgow Coma Scale (GCS), ventilator days, blood administration, or ICU/hospital length of stay when comparing the MO group with the NEG group. Significant differences occurred between the OD group and the NEG/MO/MU groups for GCS, ICU length of stay, and hospital charges. Cannabis users suffering from severe injury demonstrated no detrimental outcomes in this study compared with nondrug users.

RESUMEN

Through a review of current research, standards of care, and best practices, this paper serves as a resource for emergency physicians (EPs) caring for persons who identify as transgender and gender diverse (T/GD) in the emergency department (ED). Both patient- and physician-based research have identified existent potential knowledge gaps for EPs caring for T/GD in the ED. T/GD have negative experiences related to their gender identity when seeking emergency medical care and may even delay emergency care for fear of discrimination. Through the lens of cultural humility, this paper aims to address potential knowledge gaps for EPs, identify and reduce barriers to care, highlight gender-affirming hospital policies and protocols, and improve the care and experience of T/GD in the ED.

RESUMEN

Background/Objective: Paragangliomas are rare neuroendocrine tumors that primarily arise in the adrenal gland. Head and neck paragangliomas comprise approximately 3% of all extra-adrenal paragangliomas, with a majority of those being found in the carotid body. Recurrent laryngeal nerve paragangliomas are exceedingly rare, with only 2 reported cases found in literature review. Here, we will present the third. Case Report: The patient is a 46-year-old woman with a history of a right thyroid nodule that had been previously biopsied benign with "paucity of diagnostic material." Neck ultrasonography revealed a 7.4 cm nodule that demonstrated interval growth over a 2-year period, so it was recommended to proceed with right thyroid lobectomy and isthmusectomy. During resection, the recurrent laryngeal nerve appeared to "disappear" into the nodule, and it was resected along with the nodule to ensure proper margins. The nerve was reconstructed with an ansa cervicalis interposition graft, and the nodule was sent to pathology. Pathology revealed that the nodule was a 4.8 cm paraganglioma of the recurrent laryngeal nerve. Discussion: Paragangliomas of the head and neck are exceedingly rare. In patients who present with symptoms of dysphagia or dysphonia, further workup, including laryngoscopy and magnetic resonance imaging, could potentially identify and allow for appropriate planning for surgical resection. Conclusion: In rare cases, consideration of paraganglioma as part of the differential for thyroid nodules may assist with planning of surgery but will unlikely alter treatment.

RESUMEN

In pancreatic islet beta cells, molecular motors use cytoskeletal polymers microtubules as tracks for intracellular transport of insulin secretory granules. Beta-cell microtubule network has a complex architecture and is non-directional, which provide insulin granules at the cell periphery for rapid secretion response, yet to avoid over-secretion and subsequent hypoglycemia. We have previously characterized a peripheral sub-membrane microtubule array, which is critical for withdrawal of excessive insulin granules from the secretion sites. Microtubules in beta cells originate at the Golgi in the cell interior, and how the peripheral array is formed is unknown. Using real-time imaging and photo-kinetics approaches in clonal mouse pancreatic beta cells MIN6, we now demonstrate that kinesin KIF5B, a motor protein with a capacity to transport microtubules as cargos, slides existing microtubules to the cell periphery and aligns them to each other along the plasma membrane. Moreover, like many physiological beta-cell features, microtubule sliding is facilitated by a high glucose stimulus. These new data, together with our previous report that in high glucose sub-membrane MT array is destabilized to allow for robust secretion, indicate that MT sliding is another integral part of glucose-triggered microtubule remodeling, likely replacing destabilized peripheral microtubules to prevent their loss over time and beta-cell malfunction.

RESUMEN

An overwhelming body of evidence points to an inextricable link between race and health disparities in the United States. Although race is best understood as a social construct, its role in health outcomes has historically been attributed to increasingly debunked theories of underlying biological and genetic differences across races. Recently, growing calls for health equity and social justice have raised awareness of the impact of implicit bias and structural racism on social determinants of health, healthcare quality, and ultimately, health outcomes. This more nuanced recognition of the role of race in health disparities has, in turn, facilitated introspective racial disparities research, root cause analyses, and changes in practice within the medical community. Examining the complex interplay between race, social determinants of health, and health outcomes allows systems of health to create mechanisms for checks and balances that mitigate unfair and avoidable health inequalities. As one of the specialties most intertwined with social medicine, emergency medicine (EM) is ideally positioned to address racism in medicine, develop health equity metrics, monitor disparities in clinical performance data, identify research gaps, implement processes and policies to eliminate racial health inequities, and promote anti-racist ideals as advocates for structural change. In this critical review our aim was to (a) provide a synopsis of racial disparities across a broad scope of clinical pathology interests addressed in emergency departments-communicable diseases, non-communicable conditions, and injuries-and (b) through a race-conscious analysis, develop EM practice recommendations for advancing a culture of equity with the potential for measurable impact on healthcare quality and health outcomes.

RESUMEN

Background: Intimate partner violence (IPV) is a serious public health issue with a substantial burden on society. Screening and intervention practices vary widely and there are no standard guidelines. Our objective was to review research on current practices for IPV prevention in emergency departments and trauma centers in the USA and provide evidenced-based recommendations. Methods: An evidence-based systematic review of the literature was conducted to address screening and intervention for IPV in adult trauma and emergency department patients. The Grading of Recommendations, Assessment, Development and Evaluations methodology was used to determine the quality of evidence. Studies were included if they addressed our prespecified population, intervention, control, and outcomes questions. Case reports, editorials, and abstracts were excluded from review. Results: Seven studies met inclusion criteria. All seven were centered around screening for IPV; none addressed interventions when abuse was identified. Screening instruments varied across studies. Although it is unclear if one tool is more accurate than others, significantly more victims were identified when screening protocols were implemented compared with non-standardized approaches to identifying IPV victims. Conclusion: Overall, there were very limited data addressing the topic of IPV screening and intervention in emergency medical settings, and the quality of the evidence was low. With likely low risk and a significant potential benefit, we conditionally recommend implementation of a screening protocol to identify victims of IPV in adults treated in the emergency department and trauma centers. Although the purpose of screening would ultimately be to provide resources for victims, no studies that assessed distinct interventions met our inclusion criteria. Therefore, we cannot make specific recommendations related to IPV interventions. PROSPERO registration number: CRD42020219517.

RESUMEN

Transitioning health care information to an electronic medical record is one of the newest policies to reach the health care agenda. Nursing leaders are at the forefront to affect the design, development, implementation, and reception of an electronic medical record. Because of their clinical workflow knowledge, decision-making capacity, and leadership role, nursing leaders are able to achieve high-quality EMRs. Being proactive in the reception, design, development, and implementation of an EMR plays a role in creating an organizational culture that allows for the flow of data efficiently and accurately.
