Orientation and Onboarding Experiences of Internationally Educated Nurses Transitioning to U.S. Nursing Practice.

Nursing professional development practitioners are faced with meeting the onboarding needs of internationally educated nurses (IENs) recruited to work in the United States. The purpose of this secondary data analysis study was to assess differences between demographic characteristics, orientation, and onboarding variables and IEN's length of orientation and retention to a healthcare system. A significant difference in the length of orientation by unit assigned, degree type, and retention were discovered.

An Analysis of Orientation and Preceptorship Influence on Nurse Job Satisfaction Across Two States.

A large public nursing data set was used to determine whether orientation and/or preceptor programs impact job satisfaction among registered nurses in Maine and Massachusetts. There was no association between orientation and preceptor programs and satisfaction, nor evidence that new nurse status modified the relationship. There is a need for evaluation of orientation and preceptor programs' structure and effectiveness, and innovation is needed in promoting job satisfaction, thereby increasing nurse retention.

In vivo PSC differentiation as a platform to identify factors for improving the engraftability of cultured muscle stem cells.

Producing an adequate number of muscle stem cells (MuSCs) with robust regenerative potential is essential for the successful cell therapy of muscle-wasting disorders. We have recently developed a method to produce skeletal myogenic cells with exceptional engraftability and expandability through an in vivo pluripotent stem cell (PSC) differentiation approach. We have subsequently mapped engraftment and gene expression and found that leukemia inhibitory factor receptor (Lifr) expression is positively correlated with engraftability. We therefore investigated the effect of LIF, the endogenous ligand of LIFR, on cultured MuSCs and examined their engraftment potential. We found that LIF-treated MuSCs exhibited elevated expression of PAX7, formed larger colonies from single cells, and favored the retention of PAX7+ "reserve cells" upon myogenic differentiation. This suggested that LIF promoted the maintenance of cultured MuSCs at a stem cell stage. Moreover, LIF enhanced the engraftment capability of MuSCs that had been expanded in vitro for 12 days by 5-fold and increased the number of MuSCs that repopulated the stem cell pool post-transplantation. These results thereby demonstrated the effectiveness of our in vivo PSC differentiation platform to identify positive regulators of the engraftability of cultured MuSCs.

An Image-Rich Educational Review of Breast Pain.

Breast pain is extremely common, occurring in 70% to 80% of women. Most cases of breast pain are from physiologic or benign causes, and patients should be reassured and offered treatment strategies to alleviate symptoms, often without diagnostic imaging. A complete clinical history and physical examination is key for distinguishing intrinsic breast pain from extramammary pain. Breast pain without other suspicious symptoms and with a negative history and physical examination result is rarely associated with malignancy, although it is a common reason for women to undergo diagnostic imaging. When breast imaging is indicated, guidelines according to the American College of Radiology Appropriateness Criteria should be followed as to whether mammography, US, or both are recommended. This review article summarizes the initial clinical evaluation of breast pain and evidence-based guidelines for imaging. Additionally, the article reviews cyclical and noncyclical breast pain and provides an image-rich discussion of the imaging presentation and management of benign and malignant breast pain etiologies.

Characteristics of Maine and Massachusetts nurses interested in advanced nursing degrees.

BACKGROUND: Maine (ME) and Massachusetts (MA) nursing programs aim to develop collaborative training programs, but need to identify which nurses have interest in such programs. PURPOSE: We sought to determine sociodemographics of nurses seeking advanced nursing degrees nationally, and in ME and MA using the 2018 publicly available, National Sample Survey of Registered Nurses (NSSRN). METHODS: Weighted multivariable logistic regression for advanced degree-seeking, adjusted for sociodemographics. RESULTS: Of the n = 47,274 nurses (weighted n [Wn] = 3,608,633), 90.7 % were female, 74.1 % were white, and 15.8 % sought an advanced nursing degree on average 12.7 (SD 0.2) years after their first. Females vs. males had lower odds (OR 0.63, 95%CI [0.44-0.90]) and Black vs. White race had higher odds (OR 1.30, 95%CI [1.05-1.60]) of seeking doctorates. In Maine (Wn = 20,389), age 24-29 had higher odds (OR 2.98 (95%CI [1.06-3.74]), but in Massachusetts (Wn = 101,984), age 30+ had lower odds (OR 0.32, 95%CI [0.13-0.78]) of degree-seeking vs. <24 years. Initial nursing degrees earned between 1980 and 1989 had higher odds (OR 1.99, 95%CI [1.06-3.74]) in Maine, but between 2010 and 2014 had lower odds (OR 0.32, 95%CI [0.14-0.72]) in Massachusetts of degree-seeking, vs. before 1980. CONCLUSIONS: Targets for advanced nursing training programs may vary by state and sociodemographic profile.

Design, Implementation, and Evaluation of a Learning Needs Assessment for Nursing Professional Development Practitioners.

The purpose of this descriptive study was to highlight how a system-level education department operationalized the 2022 Association for Nursing Professional Development Scope and Standards of Practice into a learning needs assessment (LNA) survey. This was a collaborative approach to LNA design, implementation, and evaluation. The LNA conducted among nursing professional development practitioners determined areas for educational improvement, barriers to nursing professional development, and identified standards and competencies critical to improving knowledge acquisition.

The Effect of Simulation on Nursing Student Perceptions of Readiness to Provide End-of-Life Care.

Evidence suggests that nursing students in a prelicensure nursing program lack the required preparation to care for patients at the end of life (EOL), causing feelings of inadequacy and stress. New graduate nurses (years 0-5) struggle to address the needs of this patient population, leading to considering career changes. Nursing simulation has been shown to enhance competency and is gaining increasing favor in prelicensure nursing education. Little research has been conducted on the application of simulation using standardized patients in EOL patient scenarios. This study used live standardized patients who simulated a home health patient encounter with the nursing student acting as a home health hospice nurse. Watson's theory of caring and interpretive phenomenological analysis guided the qualitative research method and analysis. Five students chose to participate in this simulation and completed 6 reflective questions. After simulation, they felt more comfortable having difficult discussions about EOL care, treatment options, and patient fears. Participants noted the importance of communication in a team setting, which included the caregiver as an integral member. The use of standardized patient-simulated experiences increases realism and provides students the opportunity to bridge the gap between didactic education and clinical practice. This will enhance their readiness and confidence in providing EOL care.

Wellness in Nursing Education to Promote Resilience and Reduce Burnout: Protocol for a Holistic Multidimensional Wellness Intervention and Longitudinal Research Study Design in Nursing Education.

BACKGROUND: The United States faces a nursing shortage driven by a burnout epidemic among nurses and nursing students. Nursing students are an integral population to fuel the nursing workforce at high risk of burnout and increased rates of perceived stress. OBJECTIVE: The aim of this paper is to describe WellNurse, a holistic, interdisciplinary, multidimensional longitudinal research study that examines evidence-based interventions intended to reduce burnout and increase resilience among graduate and undergraduate nursing students. METHODS: Graduate and undergraduate nursing students matriculated at a large public university in the northeastern United States are eligible to enroll in this ongoing, longitudinal cohort study beginning in March 2021. Participants complete a battery of health measurements twice each semester during the fourth week and the week before final examinations. The measures include the Perceived Stress Scale, the Satisfaction with Life Scale, the Oldenburg Burnout Inventory, the Brief Resilience Scale, and the Pittsburgh Sleep Quality Index. Participants are eligible to enroll in a variety of interventions, including mindfulness-based stress reduction, mindful eating, fitness training, and massage therapy. Those who enroll in specific, targeted interventions complete additional measures designed to target the aim of the intervention. All participants receive a free Fitbit device. Additional environmental changes are being implemented to further promote a culture that supports academic well-being, including recruiting a diverse student population through evidence-based holistic admissions, inclusive teaching design, targeted resilience and stress reduction workshops, and cultural shifts within classrooms and curricula. The study design protocol is registered at Open Science Framework (DOI 10.17605/OSF.IO/NCBPE). RESULTS: The project was funded on January 1, 2022. Data collection started in March 2022. A total of 267 participants have been recruited. Results will be published after each semester starting in December 2023. WellNurse evaluation follows the Rapid Cycle Quality Improvement framework to continuously monitor ongoing project processes, activity outcomes, and progress toward reducing burnout and increasing resilience. Rapid Cycle Quality Improvement promotes the ability to alter WellNurse interventions, examine multiple interventions, and test their effectiveness among the nursing education population to identify the most effective interventions. CONCLUSIONS: Academic nursing organizations must address student burnout risk and increase resilience to produce a future workforce that provides high-quality patient care to a diverse population. Findings from WellNurse will support evidence-based implementations for public baccalaureate and master's nursing programs in the United States.

Salicylic acid metabolism and signalling coordinate senescence initiation in aspen in nature.

Deciduous trees exhibit a spectacular phenomenon of autumn senescence driven by the seasonality of their growth environment, yet there is no consensus which external or internal cues trigger it. Senescence starts at different times in European aspen (Populus tremula L.) genotypes grown in same location. By integrating omics studies, we demonstrate that aspen genotypes utilize similar transcriptional cascades and metabolic cues to initiate senescence, but at different times during autumn. The timing of autumn senescence initiation appeared to be controlled by two consecutive "switches"; 1) first the environmental variation induced the rewiring of the transcriptional network, stress signalling pathways and metabolic perturbations and 2) the start of senescence process was defined by the ability of the genotype to activate and sustain stress tolerance mechanisms mediated by salicylic acid. We propose that salicylic acid represses the onset of leaf senescence in stressful natural conditions, rather than promoting it as often observed in annual plants.

Genetic markers and tree properties predicting wood biorefining potential in aspen (Populus tremula) bioenergy feedstock.

BACKGROUND: Wood represents the majority of the biomass on land and constitutes a renewable source of biofuels and other bioproducts. However, wood is recalcitrant to bioconversion, raising a need for feedstock improvement in production of, for instance, biofuels. We investigated the properties of wood that affect bioconversion, as well as the underlying genetics, to help identify superior tree feedstocks for biorefining. RESULTS: We recorded 65 wood-related and growth traits in a population of 113 natural aspen genotypes from Sweden ( https://doi.org/10.5061/dryad.gtht76hrd ). These traits included three growth and field performance traits, 20 traits for wood chemical composition, 17 traits for wood anatomy and structure, and 25 wood saccharification traits as indicators of bioconversion potential. Glucose release after saccharification with acidic pretreatment correlated positively with tree stem height and diameter and the carbohydrate content of the wood, and negatively with the content of lignin and the hemicellulose sugar units. Most of these traits displayed extensive natural variation within the aspen population and high broad-sense heritability, supporting their potential in genetic improvement of feedstocks towards improved bioconversion. Finally, a genome-wide association study (GWAS) revealed 13 genetic loci for saccharification yield (on a whole-tree-biomass basis), with six of them intersecting with associations for either height or stem diameter of the trees. CONCLUSIONS: The simple growth traits of stem height and diameter were identified as good predictors of wood saccharification yield in aspen trees. GWAS elucidated the underlying genetics, revealing putative genetic markers for bioconversion of bioenergy tree feedstocks.

Quantitative Biomarkers Derived from a Novel Contrast-Free Ultrasound High-Definition Microvessel Imaging for Distinguishing Thyroid Nodules.

Low specificity in current ultrasound modalities for thyroid cancer detection necessitates the development of new imaging modalities for optimal characterization of thyroid nodules. Herein, the quantitative biomarkers of a new high-definition microvessel imaging (HDMI) were evaluated for discrimination of benign from malignant thyroid nodules. Without the help of contrast agents, this new ultrasound-based quantitative technique utilizes processing methods including clutter filtering, denoising, vessel enhancement filtering, morphological filtering, and vessel segmentation to resolve tumor microvessels at size scales of a few hundred microns and enables the extraction of vessel morphological features as new tumor biomarkers. We evaluated quantitative HDMI on 92 patients with 92 thyroid nodules identified in ultrasound. A total of 12 biomarkers derived from vessel morphological parameters were associated with pathology results. Using the Wilcoxon rank-sum test, six of the twelve biomarkers were significantly different in distribution between the malignant and benign nodules (all p < 0.01). A support vector machine (SVM)-based classification model was trained on these six biomarkers, and the receiver operating characteristic curve (ROC) showed an area under the curve (AUC) of 0.9005 (95% CI: [0.8279,0.9732]) with sensitivity, specificity, and accuracy of 0.7778, 0.9474, and 0.8929, respectively. When additional clinical data, namely TI-RADS, age, and nodule size were added to the features, model performance reached an AUC of 0.9044 (95% CI: [0.8331,0.9757]) with sensitivity, specificity, and accuracy of 0.8750, 0.8235, and 0.8400, respectively. Our findings suggest that tumor vessel morphological features may improve the characterization of thyroid nodules.

Spectrum of imaging findings in hyperplastic cholecystosis and potential mimics.

Adenomyomatosis and cholesterolosis of the gallbladder, collectively termed hyperplastic cholecystosis, are commonly encountered incidental findings on imaging studies performed for a variety of indications including biliary colic or nonspecific abdominal pain. These pathologies are rarely the source of symptoms, generally considered benign and do not require further work-up. However, their imaging characteristics can overlap with more sinister conditions that should not be missed. In this review, the imaging findings of adenomyomatosis and cholesterolosis will be reviewed followed by other gallbladder pathologies that might mimic these conditions radiologically. Important differentiating factors will be discussed that can aid the radiologist in making a more confident imaging diagnosis.

Adaptive and Robust Vessel Quantification in Contrast-Free Ultrafast Ultrasound Microvessel Imaging.

The morphological features of vasculature in diseased tissue differ significantly from those in normal tissue. Therefore, vasculature quantification is crucial for disease diagnosis and staging. Ultrasound microvessel imaging (UMI) with ultrafast ultrasound acquisitions has been determined to have potential in clinical applications given its superior sensitivity in blood flow detection. However, the presence of spatial-dependent noise caused by a low imaging signal-to-noise ratio and incoherent clutter artifacts caused by moving hyperechoic scatterers degrades the performance of UMI and the reliability of vascular quantification. To tackle these issues, we proposed an improved UMI technique along with an adaptive vessel segmentation workflow for robust vessel identification and vascular feature quantification. A previously proposed sub-aperture cross-correlation technique and a normalized cross-correlation technique were applied to equalize the spatially dependent noise level and suppress the incoherent clutter artifact. A square operator and non-local means filter were then used to better separate the blood flow signal from residual background noise. On the de-noised ultrasound microvessel image, an automatic and adaptive vessel segmentation method was developed based on the different spatial patterns of blood flow signal and background noise. The proposed workflow was applied to a CIRS phantom, to a Doppler flow phantom and to an inflammatory bowel, kidney and liver, to validate its feasibility. Results revealed that automatic adaptive, and robust vessel identification performance can be achieved using the proposed method without the subjectivity caused by radiologists/operators.

Obesity: Policy and Practice Recommendations for High-Risk Populations Influenced by the COVID-19 Pandemic.

Obesity has been linked to higher morbidity and mortality in those that contract novel viruses, such as H1N1 and SARS-CoV-2. Loss of life and the high cost of obesity highlight the need to focus on preventative measures. The state of Maine (United States) is profiled as a rural state with high rates of obesity and low health literacy that benefits from programs to improve health. However, more multidirectional efforts are needed. Four recommendations for building a healthier, more resilient patient population are discussed here: (i) state incentives and subsidies, (ii) employers to incentivize healthy living, (iii) federal incentives and initiatives, and (iv) personal responsibility for health and wellness.

Pain and Spiritual Distress at End of Life: A Correlational Study.

Objective: The purpose of this study is to examine the relationship between unmanaged pain and spiritual distress in adults newly admitted to hospice. Background: Current evidence supports the presence of a positive relationship between increased physical pain and spiritual distress for those with advanced cancer and/or receiving palliative care services. Nonetheless, spiritual distress remains a relatively understudied area; anecdotally, assessment and management of physical symptoms often take precedence over interventions for spiritual distress in patients at end of life (EOL) on hospice. Further research is needed to examine the relationships between physical pain, spiritual distress, and factors such as age, gender, and religious affiliation/spiritual practice specific to EOL patients receiving home hospice care. The Total Pain Model underpins this study. Methods: In this cross-sectional correlational study, pre-existing data were extracted from a hospice agency's electronic health record (EHR) to examine age, gender, marital status, race/ethnicity, religious affiliation and/or spiritual practice, hospice diagnosis, pain severity, and spiritual distress in adult patients (age 18 and over) admitted to home hospice services (N = 3484). Descriptive, bivariate, and multivariate analyzes were conducted. Results: The age range for this sample was 25 to 107 years old (M = 82, SD = 12.08). Over half of the sample were female and white. One third of the patients were married or had a designated life partner. Over 85% identified as either Catholic or Protestant. Sixteen percent reported moderate to severe pain and 9.6% experienced spiritual distress. Marital status (χ2 (3, N = 2483) = 20.21, P < .001, Cramer's V = .09), hospice diagnosis (χ2 (5, N = 3481) = 22.66, P < .001, Cramer's V = .08), pain severity (χ2 (1, N = 3464) = 19.75, P < .001, Cramer's V = .08), and age (t (393.17) = 2.84, P = .005, d = .17) were significantly related to spiritual distress. The binary logistic model was statistically significant, χ2 (11) = 45.25, P < .001, and cases indicating the highest odds of experiencing spiritual distress had pulmonary disease (OR = 1.8, P = .02), were single (OR = 1.6, P = .02), and had moderate to severe pain (OR = 1.4, P = .04). Conclusions: Moderate to severe pain, marital status, and diagnosis should be considered for inclusion in a refined spiritual distress hospice admission screening process. Future research should examine the unique contributions of diagnosis in predicting spiritual distress, particularly pulmonary disease.

Worry About the Future Health Issues of Smoking and Intention to Screen for Lung Cancer With Low-Dose Computed Tomography.

BACKGROUND: Early diagnosis of lung cancer is key to improving the long-term prognosis for many individuals. Still, utilization rates of lung cancer screening (LCS) remain low. OBJECTIVE: To investigate the association between worry about future health issues of smoking and intention to undergo recommended LCS with low-dose computed tomography (LDCT) within the next 3 months. METHODS: A cross-sectional online survey was conducted using the Qualtrics Panel to recruit adult smokers between ages 54 and 75 years, with no history of lung cancer, and at least 30-pack-year smoking history (n = 152). The survey gathered demographic, socioeconomic, and psychographic information, including intention to screen for lung cancer with LDCT and worry about the future health issues of smoking. Data were analyzed using multivariable logistic regression. RESULTS: Approximately 43.0% were White, 21.7% were Black, and 60.0% were female. Most (86.0%) reported intentions to undergo recommended LCS with LDCT in the next 3 months. More than one-third (32.0%) reported moderately/very worried about the future health issues of smoking. Smokers who were moderately/very worried had 20% (P = .022) higher odds of reporting an intention to undergo LCS with LDCT than those who were not at all or a little worried. CONCLUSIONS: Most eligible adults reported intentions to undergo LCS with LDCT. Our study also highlights sex, racial, and socioeconomic differences in LCS behavior. IMPLICATIONS FOR PRACTICE: The study findings provide an opportunity for healthcare providers to have in-depth discussions about the benefits of LCS with those who express worry about future health issues of smoking.

Analysis and Classification of Postcatheterization Femoral Arteriovenous Fistulas Based on Color Doppler Examinations.

OBJECTIVE: To analyze and classify arterial supply and venous drainage of postcatheterization femoral arteriovenous fistulas (AVFs). METHODS: A review of extremity Doppler reports identified 77 femoral AVFs in 75 patients. Doppler exams were reviewed retrospectively. Fistulas were classified as above or below the common femoral artery bifurcation and subclassified based on the location of arterial inflow and venous outflow. RESULTS: Arterial inflow originated above the femoral bifurcation in 32 cases. The communication was between the common femoral artery and the superficial circumflex iliac vein in 25 of 32 cases and between a branch of the common femoral or external iliac artery and the common femoral or external iliac vein in 4 of 32 cases. In 3 of 32 cases, AVFs arose from the common femoral artery, but the venous outflow was not determined. Arterial inflow originated from the superficial femoral artery in 23 cases. Venous outflow originated from the common femoral vein in 10 of 23 cases, the femoral vein in 7 of 23 cases, and the lateral circumflex femoral vein in 6 of 23 cases. Arterial inflow originated from the deep femoral artery in 12 cases. Venous outflow originated from the common femoral vein in 6 of 12 cases and from the lateral circumflex femoral vein 6 of 12 cases. In 8 cases, the AVF originated below the bifurcation, but the arterial inflow was not classified. In 2 cases, it was impossible to determine if the AVF originated above or below the bifurcation. CONCLUSIONS: Iatrogenic femoral AVFs arise above the femoral bifurcation more often than previously recognized. Classification based on the arterial inflow and venous outflow provides a straightforward means of describing these fistulas.

An atlas of the Norway spruce needle seasonal transcriptome.

Boreal conifers possess a tremendous ability to survive and remain evergreen during harsh winter conditions and resume growth during summer. This is enabled by coordinated regulation of major cellular functions at the level of gene expression, metabolism, and physiology. Here we present a comprehensive characterization of the annual changes in the global transcriptome of Norway spruce (Picea abies) needles as a resource to understand needle development and acclimation processes throughout the year. In young, growing needles (May 15 until June 30), cell walls, organelles, etc., were formed, and this developmental program heavily influenced the transcriptome, explained by over-represented Gene Ontology (GO) categories. Later changes in gene expression were smaller but four phases were recognized: summer (July-August), autumn (September-October), winter (November-February), and spring (March-April), where over-represented GO categories demonstrated how the needles acclimated to the various seasons. Changes in the seasonal global transcriptome profile were accompanied by differential expression of members of the major transcription factor families. We present a tentative model of how cellular activities are regulated over the year in needles of Norway spruce, which demonstrates the value of mining this dataset, accessible in ConGenIE together with advanced visualization tools.

Adaptive Introgression Facilitates Adaptation to High Latitudes in European Aspen (Populus tremula L.).

Understanding local adaptation has become a key research area given the ongoing climate challenge and the concomitant requirement to conserve genetic resources. Perennial plants, such as forest trees, are good models to study local adaptation given their wide geographic distribution, largely outcrossing mating systems, and demographic histories. We evaluated signatures of local adaptation in European aspen (Populus tremula) across Europe by means of whole-genome resequencing of a collection of 411 individual trees. We dissected admixture patterns between aspen lineages and observed a strong genomic mosaicism in Scandinavian trees, evidencing different colonization trajectories into the peninsula from Russia, Central and Western Europe. As a consequence of the secondary contacts between populations after the last glacial maximum, we detected an adaptive introgression event in a genome region of ∼500 kb in chromosome 10, harboring a large-effect locus that has previously been shown to contribute to adaptation to the short growing seasons characteristic of Northern Scandinavia. Demographic simulations and ancestry inference suggest an Eastern origin-probably Russian-of the adaptive Nordic allele which nowadays is present in a homozygous state at the north of Scandinavia. The strength of introgression and positive selection signatures in this region is a unique feature in the genome. Furthermore, we detected signals of balancing selection, shared across regional populations, that highlight the importance of standing variation as a primary source of alleles that facilitate local adaptation. Our results, therefore, emphasize the importance of migration-selection balance underlying the genetic architecture of key adaptive quantitative traits.
