Published: June 2024

Objectives: The Centers for Disease Control and Prevention (CDC) needs leaders at all levels who can address technical and adaptive challenges in a changing public health landscape. We assessed the feasibility of implementing an enterprise-wide leadership development model. Methods: In June 2023, we launched a pilot program, Learn and Lead, for nonsupervisory staff in early and mid-career levels. One hundred sixty-nine participants registered, and 149 completed at least 6 weeks of the 8-week program. We gathered quantitative and qualitative data through weekly electronic surveys and in-depth interviews. We calculated frequencies for closed-ended Likert-scale items and performed content analysis of open-ended items to assess most frequently mentioned themes. We based the pilot’s design on CDC’s leadership development framework to assess application of the framework and alignment of curriculum to the framework. Results: Three themes emerged: logistics and facilitation, leadership development curriculum, and making connections with self and others. Findings for logistics and facilitation highlighted preferences for course length, small breakout groups, mixed weeks, and value of staff support. Findings for the leadership development curriculum underscored the relevance of the US Office of Personnel Management’s fundamental competencies to leadership development. Findings for making connections with self and others supported the cohort model and the importance of networking. Conclusions: The pilot curriculum aligned well with the CDC leadership development framework. Feedback provided by pilot participants is being used to help shape CDC’s ongoing leadership development efforts.

Objective: The objective of this study is to explore the questions commonly asked online about biologic therapies for use in treatment of chronic sinusitis with nasal polyps (CRSwNP) and the quality of the available content. Methods: Most common search terms were identified via Google Trends. People Also Ask (PAA) questions were identified and extracted with their associated website using an online data-scraping program [Search Engine Optimization (SEO) Minion, Keywords Everywhere]. Sources were evaluated using Flesch Kincaid Grade Level (FKGL) and Flesch Reading Ease (FRE, higher number = better) score for readability; Journal of American Medical Association ( JAMA) Benchmark criteria for quality assessment (0-4, 4 = all criteria met). Results: A total of 143 unique PAA questions and unique websites were identified. Questions were organized into 3 categories: questions about biologic therapies overall (38.46%), about CRSwNP (37.76%), and about treatment options for CRSwNP (23.78%). Websites answering PAA questions were from commercial (60.14%), medical practice (13.99%), academic (13.29%), and government (12.59%) sources. FKGL scores found the average reading level to be at approximately a 12th grade level (SD = 3.297) alongside a low reading ease FRE score of 37.6 (SD = 16.77). Mean JAMA criteria scores were 0.9895 (SD = 0.848), indicating largely low-quality materials. Conclusion: Biologic therapies are a novel treatment option for CRSwNP, and participants are seeking more information about these treatments and disease state. Online resources regarding biologics should be presented at a lower reading level. Sources with evidence-based information are needed. Physicians should be aware of these limitations in online material and counsel accordingly by curating and directing patients to good sources. Level of Evidence: Step 4

Published: June 2024

Background: Methodological heterogeneity hinders data comparisons across isolated studies of tendon and ligament properties, limiting clinical understanding and affecting the development and evaluation of replacement materials. Purpose: To create an open-access data set on the morphological, biomechanical, and biochemical properties of clinically important tendons and ligaments of the lower limb, using consistent methodologies, to enable direct tendon/ligament comparisons. Study Design: Descriptive laboratory study. Methods: Nineteen distinct lower limb tendons and ligaments were retrieved from 8 fresh-frozen human cadavers (5 male, 3 female; aged 49-65 years) including Achilles, tibialis posterior, tibialis anterior, fibularis (peroneus) longus, fibularis (peroneus) brevis, flexor hallucis longus, extensor hallucis longus, plantaris, flexor digitorum longus, quadriceps, patellar, semitendinosus, and gracilis tendons; anterior cruciate, posterior cruciate, medial collateral, and lateral collateral ligaments; and 10 mm–wide grafts from the contralateral quadriceps and patellar tendons. Outcomes included morphology (tissue length, ultrasound-quantified cross-sectional area [CSAUS], and major and minor axes), biomechanics (failure load, ultimate tensile strength [UTS], failure strain, and elastic modulus), and biochemistry (sulfated glycosaminoglycan [sGAG] and hydroxyproline contents). Tissue differences were analyzed using mixed-model regression. Results: There was a range of similarities and differences between tendons and ligaments across outcomes. A key finding relating to potential graft tissue suitability was the comparable failure loads, UTS, CSAUS, sGAG, and hydroxyproline present between hamstring tendons (a standard graft source) and 5 tendons not typically used for grafting: fibularis (peroneus) longus and brevis, flexor and extensor hallucis longus, and flexor digitorum longus tendons. Conclusion: This study of lower limb tendons and ligaments has enabled direct comparison of morphological, biomechanical, and biochemical human tissue properties—key factors in the selection of suitable graft tissues. This analysis has identified 6 potential new donor tissues with properties comparable to currently used grafts. Clinical Relevance: This extensive data set reduces the need to utilize data from incompatible sources, which may aid surgical decisions (eg, evidence to expand the range of tendons considered suitable for use as grafts) and may provide congruent design inputs for new biomaterials and computational models. The complete data set has been provided to facilitate further investigations, with the capacity to expand the resource to include additional outcomes and tissues.

Published: June 2024

Background Although research has established that the work environment significantly shapes nurses’ ethical behavior, it’s less clear whether decent work could influence ethical ideologies of nurses. Aim To investigate the decent work conditions and ethical ideologies of nurses, and to analyze whether decent work influences their ethical ideologies. Methods A multicenter cross-sectional survey was conducted among 203 nurses working in three tertiary governmental hospitals across two cities in Egypt. We utilized the Scale of Decent Work, which consists of 15 items distributed across five dimensions, to assess the level of decent work conditions. Additionally, the Ethics Position Questionnaire, containing 20 items divided into two categories—idealism and relativism—was used to evaluate the ethical ideologies of nurses. Pearson correlation and linear regression analyses were applied to analyze the data. Ethical considerations Ethical approval from the ethics committee, institutional permission, and informed consent from the participants were obtained for data collection. Results The findings indicated that the levels of decent work conditions were moderate, while the ethical ideologies of nurses were relatively high. Stepwise multiple linear regression analyses revealed that the idealism of nurses was significantly predicted by two dimensions of decent work—organizational values, and hours allowing for free time and rest—along with the overall decent work score. Meanwhile, the relativism of nurses was significantly predicted by the presence of physically and interpersonally safe working conditions. Conclusions Nurses experiencing decent work conditions characterized by high organizational values and adequate hours for free time and rest are more inclined to adopt idealistic ethical ideology. Meanwhile, those experiencing physically and interpersonally safe working conditions tend to embrace relativistic ethical ideology. Implications for clinical practice Identifying the relationship between decent work conditions and the ethical ideologies of nurses can assist hospital administrators in fostering work conditions that promote appropriate ethical ideologies among nurses.
Power boundaries in resonant electrodynamic wireless power transfer systems
Authors: Morel Adrien , Gibus David , Badel Adrien 
Published: June 2024

This article focuses on deriving the maximum power that can be transmitted using recent wireless power transfer technology based on an electrodynamic receiver. Analytical derivations reveal two main constraints that can limit transmitted power: the magnetic field safety limit and the maximum stress before breaking the receiver. From these limits, expressions of maximum magnetic forces and power are derived, providing physical insights on how to optimize the transmitted power. Interestingly, the optimal electrical condition and the optimal electromechanical efficiency differ when maximizing the transmitted power under each constraint. In the final section of the paper, the proposed theoretical boundaries are applied to two types of receivers, based on either electromagnetic or piezoelectric transducers. The results demonstrate that the maximum power density achievable with both receivers is inherently limited (<10 mW/cm3) under realistic assumptions regarding electromechanical coupling and electrical circuitry. This value is smaller than some previously reported results involving rotating or magnetoelectric solutions, indicating that clamped-free beams are not the optimal solution for electrodynamic wireless power transfer. This analysis can be extended to other types of receivers and will be useful for optimizing, sizing, and assessing any technological solution for wireless power transfer.

Published: June 2024

This study establishes a three-dimensional infinite-length periodic ballasted track model, considering the effect of coupling between bending and torsion and the impact of sleeper width. The GPWE method is employed to investigate the energy bandgap structure of the track. The results show three vertical bending wave bandgaps below 1500 Hz: 0–109 Hz, 110–167 Hz, and 1081–1126 Hz. The node responses from a hammer impact experiment are used in the WSM to calculate the frequency dispersion curves, which confirms the validity of this model. The model is then utilized to analyze the influence of rail temperature forces and temperature-dependent fastener stiffness on the vibration transmission characteristics of the track within a temperature range of −35°C to 25°C. As temperature increases, the starting and cutoff frequency values and the width of bandgaps both decrease nonlinearly and later stabilize, with the width of the Bragg bandgap showing a significant reduction of 83%. The vibration attenuation rate in the bandgap gradually increases and finally stabilizes, especially above 15°C, while the vibration transfer characteristics are not significantly affected by temperature.

Published: June 2024

Background: Multiple sclerosis (MS) is frequently accompanied by comorbid conditions. Objectives: This study aimed to determine the prevalence of key comorbid conditions in people with multiple sclerosis (pwMS) and assess their impact on quality of life and work-related activities. Methods: A cross-sectional study involving 755 pwMS from two third-level Italian MS centers was conducted. Comorbidities were identified from medical records, and quality of life was assessed using the EQ-5D-3L questionnaire. Work-related challenges were evaluated using the Multiple Sclerosis Questionnaire for Job Difficulties (MSQ-Job). Results: 53.8% of pwMS had at least one comorbidity. Hypertension, depression, and anxiety were the most prevalent. Comorbidity presence was associated with reduced quality of life scores in almost all EQ-5D-3L domains and greater job difficulties in all but one MSQ-Job domain. Conclusion: Comorbidities in pwMS are prevalent and have a profound influence on quality of life and work-related activities. This comprehensive study offers new insights into the role of comorbidities in MS within the Italian context, emphasizing the need for a multidisciplinary approach in MS management. Further research is crucial to deepen our understanding of these findings in the broader Italian MS community.

Published: June 2024

Objectives Endoleaks are important complications of endovascular aortic repair. Usually, endoleaks are judged indirectly by aortography or postoperative computed tomography. However, findings from these modalities are difficult to distinguish because of the divergency of endoleaks. Few studies have reported direct visualization of endoleaks. Herein, we introduce a direct procedure for intraoperatively evaluating endoleaks using angioscopy. Methods From April 2023, consecutive patients with an abdominal aortic aneurysm, except emergency cases and those of narrow access, seen at Sunagawa City Medical Center were enrolled in our study. Endoleaks were detected by intraoperative angioscopy using a novel endovascular procedure. Results Seven patients underwent endovascular aortic repair of an abdominal aortic aneurysm with intraoperative angioscopy. None of the enrolled patients experienced complications. The procedure revealed types 2, 3a, and 4 endoleaks. Conclusions This is the first study to demonstrate intraoperative visualization of endoleaks using angioscopy. Direct findings observed by this novel procedure might provide information on the velocity and volume of the endoleak, providing comprehensive insights into the intra-sac hemodynamics after the endovascular aortic repair.

Published: June 2024

Context: Movement velocity (MV) may be a valid tool to evaluate and control the load in resistance training (RT). The rating of perceived exertion (RPE) also enables practical load management. The relationship between RPE and MV may be used to monitor RT intensity. Objective: To evaluate the validity and practicality of RPE scales related to MV and training intensity in resistance exercise. We hypothesize a positive correlation among RPE, MV, and load intensity in RT. Therefore, RPE may serve as a supplementary indicator in monitoring RT load. Data Sources: Boolean algorithms were used to search several databases (SPORTDiscus, EBSCO, PubMed, Scopus, and Google Scholar). Study Selection: Studies published from 2009 to 2023 included clinical trials (randomized or not) in healthy female and male subjects that analyzed the relationship between different RPE scales and MV in basic RT exercises. Study Design: Systematic review. Level of Evidence: Level 3. Results: A total of 18 studies were selected using different RPE scales with reported MV training loads. Participants included RT and untrained male and female subjects (15-31 years old). Two RPE scales (OMNI-RES and repetitions in reserve) were used. The selected studies showed moderate positive correlations among these RPE scales, MV, and training load (eg, percentage of 1-repetition maximum [%1-RM]). In addition, equations have been developed to estimate %1-RM and MV loss based on the OMNI-RES scale. Conclusion: Studies show that RPE scales and MV constitute a valid, economic, and practical tool for assessing RT load progression and complementing other training monitoring variables. Exercise professionals should consider familiarizing participants with RPE scales and factors that might influence the perception of exertion (eg, level of training, motivation, and environmental conditions).

Authors: Nair Vishnu Vikraman , Kundnani Vishal 
Published: June 2024

Study Design Retrospective Cohort Study. Objective The primary objective of this study is to evaluate the efficacy of early administration of Teriparatide in preventing the necessity of surgical intervention in individuals with osteoporotic vertebral compression fractures. Methods In a 24-month follow-up retrospective analysis, 191 OVCF patients from January 2016 to October 2020 were randomly assigned to Non teriparatide Group A (n = 104) or Group B teriparatide (n = 87). At baseline, 6 months, 1 year, and 2 years following treatment, demographic data and need of surgical intervention, VAS, ODI, union rates, and kyphosis development, were examined. Results Our study found that non-teriparatide group individuals had an 11.53% higher risk of non-union formation that required surgery. Only 8.63% of teriparatide group patients needed surgery. Both groups had significant VAS score reductions. Non-teriparatide group scores declined from 8.38 ± 0.74 to 3.15 ± 1.40, while teriparatide group scores decreased from 8.49 ± 0.73 to 1.11 ± 0.31. The 2-year follow-up ODI scores significantly decreased, with values of 25.02 ± 13.94 for non-teriparatide patients and 15.11 ± 2.17 for teriparatide patients. The kyphosis progression angles in the teriparatide group were considerably lower (4.97 ± 0.78°) compared to the other group (8.09 ± 1.25°). Conclusion With increasing elderly populations, it is necessary to take measures to prevent surgical intervention in osteoporotic spinal compression fractures. Teriparatide can be employed as an early medication in the management of these fractures to avert non-union and the minimise the progression of kyphosis.

Published: June 2024

Background: Treatment for substance use disorders (SUD) remains low in the United States. To better meet needs of people who use alcohol and other drugs, low threshold bridge clinics which offer treatment without barrier and harm reduction services have gained prevalence. Bridge clinics work to surmount barriers to care by providing same day medication and treatment for SUD and eventually transitioning patients to community-based treatment providers. In this study, we examine SUD treatment outcomes among patients who transitioned out of a bridge clinic. Methods: This is a retrospective cohort study of posttreatment outcomes of patients seen at an urban medical center’s bridge clinic between 2017 and 2022. The primary outcome was being in care anywhere at time of follow-up. We also examined the proportion of patients who completed each step of the cascade of care following transfer: connection to transfer clinic, completion of a clinic visit, retention in care, and medication use among those remaining in care at the transfer clinic. We examined the association of different bridge clinic services with still being in care anywhere and the association between successful transfer with being in care and taking medication at follow-up. Results: Of 209 eligible participants, 63 were surveyed. Sixty-five percent of participants identified as male, 74% as white, 12% as Hispanic, 6% as Black, and 16% were unhoused. Most participants (78%) reported being connected to SUD treatment from the Bridge Clinic, and 37% remained in care at the same facility at the time of survey. Eighty-four percent reported being in treatment anywhere and 68% reported taking medication for SUD at follow-up, with most participants reporting taking buprenorphine (46%). Conclusion: Of those participants who transitioned out of a bridge clinic into community-based SUD care, 78% were successfully connected to ongoing care and 84% were still in care at follow-up.

Published: June 2024

Abstract
Background and aims
Electrophysiological characteristics and radiofrequency catheter ablation (RFCA) of premature ventricular contractions (PVCs) originating from the superior septal left ventricle (SSLV) have not yet been fully characterized.

Methods and results
This study included 247 patients who underwent RFCA for PVCs arising from the ventricular outflow tract between February 2020 and August 2022. The successful ablation site was on the SSLV in 37 of the 247 patients. In 12 (32.4%) of those 37 patients, a low amplitude and high frequency spiky potential (SP) was recognized. Five patients showed a narrow QRS duration (86.8 ± 4.6 ms), with a discrete SP observed in PVCs and sinus rhythm, which showed an isoelectric line with the ventricular electrogram at the earliest activation site. Seven patients showed a wide QRS duration (131.6 ± 4.5 ms), with SP observed in PVCs without an isoelectric line with the ventricular electrogram. RFCA was successful at the site of the earliest SP in all 12 patients. The time from SP onset at the successful ablation site to the QRS onset (local activation time) was 30 ± 12 ms, which differed significantly from that for the remaining 25 patients withoutSP(22.1 ± 7.1 ms, P < 0.05).

Conclusions
SPs were recorded in 12 (32.4%) of the 37 patients with PVCs originating from the SSLV. The morphology of the PVCs may show a narrow or wide QRS duration and the target site for successful ablation should be identified by the earliest SP.
