RESUMEN

BACKGROUND: Integration of genomic content into nursing curricula and continuing education is limited. PURPOSE: This systematic review aimed to identify educational strategies to deliver genomics content. METHODS: CINAHL Plus, ERIC, Ovid MEDLINE, and Scopus electronic databases were searched from January 1, 2003 through July 6, 2023. The three domains of learning: cognitive, affective, and psychomotor were used to categorize educational outcomes. A narrative approach was used to synthesize the data using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. DISCUSSION: Ten studies met inclusion criteria. Quality assessment for bias was conducted independently; study quality ranged from fair to poor. No study used a complete psychometrically tested instrument to measure genomic cognitive or affective knowledge; none measured the psychomotor domain. CONCLUSIONS: Effective strategies to deliver genomic education are a priority. Development of reliable and valid instruments for the assessment of educational interventions, including the psychomotor skills needed for practice.

RESUMEN

PURPOSE OF REVIEW: To summarize the current use of cardiac computed tomography (CT) technologies as well as their pertinent evidence in regards to prevention of coronary artery disease (CAD). RECENT FINDINGS: Cardiac CTA has now become a main non-invasive method for the evaluation of symptomatic CAD. In addition to coronary calcium score, other CT technologies such as atherosclerotic plaque analysis, fractional flow reserve estimation by CT, pericoronary fat attenuation, and endothelial wall shear stress have emerged. Whether the use of CT modalities can enhance risk prediction and prevention in CAD has not been fully answered. We discuss the evidence for coronary artery calcium scoring and coronary CT angiography in primary prevention and the current barriers to their use. We attempt to delineate what can be done to expand use and what studies are needed to broaden adoption in the future. We also examine the potential roles of emerging CT technologies. Finally, we describe potential clinical approaches to prevention that would incorporate cardiac CT technologies.

RESUMEN

Financial considerations continue to impact access to heart transplantation. Transplant recipients face various costs, including, but not limited to, the index hospitalization, immunosuppressive medications, and lodging and travel to appointments. In this study, we sought to describe the state of crowdfunding for individuals being evaluated for heart transplantation. Using the search term heart transplant, 1000 GoFundMe campaigns were reviewed. After exclusions, 634 (63.4%) campaigns were included. Most campaigns were in support of white individuals (57.8%), males (63.1%) and adults (76.7%). Approximately 15% of campaigns had not raised any funds. The remaining campaigns fundraised a median of $53.24 dollars per day. Of the patients, 44% were admitted at the time of the fundraising. Within the campaigns in the United States, the greatest proportions were in the Southeast United States in non-Medicaid expansion states. These findings highlight the significant financial toxicities associated with heart transplantation and the need for advocacy at the governmental and payer levels to improve equitable access and coverage for all.

RESUMEN

BACKGROUND: Oropharyngeal cancer (OPC) survivorship is a nursing priority because patients are living longer while significant short-term and long-term treatment complications that require nursing care are increasing. Hospital readmission is costly and reflects the quality of care patients receive. OBJECTIVES: This secondary analysis aimed to determine the prevalence of treatment complications resulting in hospital admissions among persons with OPC and examine the relationship between treatment complications resulting in hospital admission among persons with OPC and all other persons with head and neck cancer. METHODS: Using the National Inpatient Survey 2008-2019 database, we identified persons with relevant head and neck cancer diagnoses using specific International Classification of Disease ICD-9 and ICD-10 codes. Complications were operationalized by diagnosis-related codes; persons with codes for major elective surgery were excluded as our focus was posttreatment symptoms requiring hospitalization. Descriptive statistics were used to characterize persons with OPC hospitalized between 2008 and 2019. Binary logistic regression was used to assess complications using crude comparisons. The Elixhauser Comorbidity Index was used for controlling for comorbidities. RESULTS: The final analysis samples included 751,533: 164,770 persons with OPC and 586,763 with other head and cancers. The most prevalent diagnoses observed in those with OPC were esophagitis, nutrition disorder, hematological disorder, and renal failure; the least common diagnoses were sepsis, respiratory tract infection, and pneumonia. Binary regression revealed that persons with OPC experienced significantly more esophagitis, nutrition disorders, hematological disorders, and renal failure compared to persons with other head and neck cancers. DISCUSSION: Treatment of survivors of OPC requires more intensive monitoring for early symptoms associated with treatment, including esophagitis, nutrition disorders, bleeding disorders, and renal failure, than persons with other head and neck cancers. Monitoring laboratory values and clinical manifestations of these conditions is imperative. Nurses may encounter persons with OPC in emergency departments, outpatient radiology, or inpatient general medicine floors to manage swallowing difficulties, dehydration, malnutrition, and bleeding. Delayed or ineffective treatment of these conditions contributes to readmission, financial burden, and impairment of patient's quality of life. Future research should investigate the relationship between targeted treatment for expected complications and readmission rates in persons with OPC.

RESUMEN

BACKGROUND: Physical violence against nurses is a concern in the United States; however, its prevalence is not well quantified. OBJECTIVE: We sought to describe the prevalence of workplace violence against nurses in the United States over a 22-year period. METHODS: A meta-analysis was performed following a literature search of English texts through Scopus, CINAHL Plus, and Ovid MEDLINE. Inclusion criteria included the following: (1) primary reports of workplace violence incidents in the United States against nurses, (2) perpetrator was a patient, family member, or visitor, and (3) publications between January 1, 2000, and June 21, 2022. Reports where prevalence rates for nurses could not be calculated were excluded. Study quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology checklist. RESULTS: Thirty-seven studies met the inclusion criteria; 27 030 nurses were included. The pooled prevalence of workplace violence was 0.35 (95% confidence interval [CI]: 0.29-0.42; Q = 3189.40; I2 = 98.87). Pooled rates of workplace violence increased from 30% in 2000 to 2004 to 43% in 2020 to 2022; however, the overlapping CIs indicate that the increase may not be statistically significant. The mean prevalence of reported workplace violence among nurses who work in the emergency department, in corrections, and psychiatric mental health settings (pooled prevalence = 0.59, 95% CI: 0.46-0.71) was higher than that of nurses who worked in all other settings (pooled prevalence = 0.24, 95% CI: 0.18-0.30). CONCLUSIONS: Workplace violence is a significant and potentially increasing problem for nurses in the United States. This critical problem requires an effective response from nurse policymakers.

RESUMEN

AIM: To test the feasibility and accuracy of a new attention-based deep learning (DL) method for right ventricular (RV) quantification using 2D echocardiography (2DE) with cardiac magnetic resonance imaging (CMR) as reference. METHODS AND RESULTS: We retrospectively analyzed images from 50 adult patients (median age 51, interquartile range 32-62 42% women) who had undergone CMR within 1 month of 2DE. RV planimetry of the myocardial border was performed in end-diastole (ED) and end-systole (ES) for eight standardized 2DE RV views with calculation of areas. The DL model comprised a Feature Tokenizer module and a stack of Transformer layers. Age, gender and calculated areas were used as inputs, and the output was RV volume in ED/ES. The dataset was randomly split into training, validation and testing subsets (35, 5 and 10 patients respectively). Mean RVEDV, RVESV and RV ejection fraction (EF) were 163 ± 70 mL, 82 ± 42 mL and 51% ± 8% respectively without differences among the subsets. The proposed method achieved good prediction of RV volumes (R2  = .953, absolute percentage error [APE] = 9.75% ± 6.23%) and RVEF (APE = 7.24% ± 4.55%). Per CMR, there was one patient with RV dilatation and three with RV dysfunction in the testing dataset. The DL model detected RV dilatation in 1/1 case and RV dysfunction in 4/3 cases. CONCLUSIONS: An attention-based DL method for 2DE RV quantification showed feasibility and promising accuracy. The method requires validation in larger cohorts with wider range of RV size and function. Further research will focus on the reduction of the number of required 2DE to make the method clinically applicable.

RESUMEN

BACKGROUND: The purpose is to compare youth- and caregiver-reported characteristics of family environment, within and between families with a child experiencing a first manic episode of bipolar disorder (BPD), and families without a child with BPD or familial history of psychiatric disorders (HF). METHODS: Family environment of 61 families with a child with BPD and 44 HF were assessed with Family Environment Scale (FES). We compared FES subscale scores between families with BPD and HF, and caregiver- and youth-rated scores. RESULTS: Families with BPD differed significantly from HF on 8/10 FES subscales scores. Youth differed significantly from their caregivers on 7/10 subscales. An interaction effect was observed such that youth with BPD reported lower cohesion and organization, and higher conflict than their caregivers; however, HF did not differ significantly on these domains. CONCLUSIONS: Our results suggest that families with BPD have higher conflict and lower cohesion and organization compared to HF. Results also indicate differences between youth and caregiver perspectives in both groups, which may contribute to family discord. Interventions targeting areas of cohesion, organization, and conflict may be beneficial for youth with BPD and their families, specifically those that identify and bridge perceptual divides.

RESUMEN

A 2012 American Heart Association statement concluded that children with CHD are at an increased risk for neurodevelopmental delays. Routine surveillance and evaluation throughout childhood are recommended. To assess paediatric cardiologist compliance with American Heart Association guidelines and developmental referral practices, a survey was distributed to paediatric cardiologists nationwide (n = 129). The majority of participants (69%) stated they were somewhat familiar or not familiar with the American Heart Association statement and were concerned about patients not being properly referred to specialists for developmental evaluation. Forty paediatric cardiologists (31%) indicated that their institution did not have a neurodevelopmental cardiology programme. Of these, 25% indicated they generally did not refer CHD patients for neurodevelopmental evaluation, 45% performed surveillance and referred if warranted, and 30% generally referred all patients for surveillance. Lastly, 43% of paediatric cardiologists did not feel responsible for developmental surveillance, and 11% did not feel responsible for referrals. To ensure all children with CHD are appropriately screened and referred, paediatricians and cardiologists must work together to address differing impressions of accountability for surveillance and screening of children with CHD.

RESUMEN

The article by Moser et al. details the outcomes of 11 patients with inflammatory bowel disease (IBD) as the main manifestation of their immune deficiency syndrome who are treated with allogeneic transplantation. The authors report low rates of complications (including graft-versus-host disease) and resolution of symptoms. Here we outline whether allogeneic transplantation should be considered more broadly for IBD. Commentary on: Moser et al. Treatment of inborn errors of immunity patients with inflammatory bowel disease phenotype by allogeneic stem cell transplantation. Br J Haematol 2023;200:595-607.

RESUMEN

B cells play crucial roles in cell-mediated alloimmune responses. In vitro, B cells can support or regulate indirect T-cell alloreactivity in response to donor antigens on ELISpot and these patterns associate with clinical outcome. Previous reports of associations between B-cell phenotype and function have examined global phenotypes and responses to polyclonal stimuli. We hypothesized that studying antigen-specific B cells, using samples from sensitized patients, would inform further study to identify novel targets for intervention. Using biotinylated HLA proteins, which bind HLA-specific B cells via the B-cell receptor in a dose-dependent fashion, we report the specific phenotype of HLA-binding B cells and define how they associated with patterns of anti-HLA response in interferon-γ ELISpot. HLA-binding class-switched and IgM+CD27+ memory cells associated strongly with B-dependent interferon-γ production and appeared not suppressible by endogenous Tregs. When the predominant HLA-binding phenotype was naïve B cells, the associated functional ELISpot phenotype was determined by other cells present. High numbers of non-HLA-binding transitional cells associated with B-suppressed interferon-γ production, especially if Tregs were present. However, high frequencies of HLA-binding marginal-zone precursors associated with B-dependent interferon-γ production that appeared suppressible by Tregs. Finally, non-HLA-binding marginal zone precursors may also suppress interferon-γ production, though this association only emerged when Tregs were absent from the ELISpot. Thus, our novel data provide a foundation on which to further define the complexities of interactions between HLA-specific T and B cells and identify new targets for intervention in new therapies for chronic rejection.

RESUMEN

Introduction: The COVID-19 pandemic has hastened the adoption of telehealth and the drastic shift to an unfamiliar process may impose significant impact to the quality-of-care delivery. Many providers are interested in understanding the quality of their telehealth services from the patients' experience. Materials and Methods: A telehealth patient satisfaction survey (TPSS) was developed by using an iterative stakeholder-centered design approach, incorporating elements from validated telemedicine and customer service survey instruments, and meeting the operational needs and constraints. A cross-sectional study design was employed to collect survey responses from patients and families of a large pediatric hospital. Finally, we performed exploratory factor analysis (EFA) to extract latent constructs and factor loadings of the survey items to further explain relationships. Results: A 22-item TPSS closely matched the existing in-person patient satisfaction survey and mapped to a revised SERVPERF conceptual model that was proposed by the interdisciplinary committee. Survey was implemented in the HIPAA-compliant online platform REDCap® with survey link embedded in an automated Epic MyChart (Verona, WI) visit follow-up message. In total, 2,394 survey responses were collected between July 7, 2020, and September 2, 2020. EFA revealed three constructs (with factor loadings >0.30): admission process, perceived quality of services, and telehealth satisfaction. Conclusions: We reported the development of TPSS that met the operational needs of compatibility with existing data and possible comparison to in-person survey. The survey is short and yet covers both the clinical experience and telehealth usability, with acceptable survey validity.

RESUMEN

INTRODUCTION: Abortion became decriminalised in Northern Ireland in October 2019. Until that point there existed no evidence concerning the views of health professionals on decriminalisation or on their willingness to be involved in abortion care. The purpose of this study was to address this lack of evidence, including all categories of health professionals working in obstetrics and gynaecology units in Northern Ireland. METHODS: The online survey was targeted at medical, nursing and midwifery staff working in the obstetrics and gynaecology units in each Health and Social Care (HSC) Trust in Northern Ireland. The survey was issued via clinical directors in each Trust using the REDCap platform. RESULTS: The findings showed widespread support for decriminalisation of abortion up until 24 weeks' gestation (n=169, 54%). The majority of clinicians stated they were willing to provide abortions in certain circumstances (which were undefined) (n=188, 60% medical abortions; n=157, 50% surgical abortions). Despite regional variation, the results show that there are sufficient numbers of clinicians to provide a service within each HSC Trust. The results indicate that many clinicians who report a religious affiliation are also supportive of decriminalisation (n=46, 51% Catholic; n=53, 45% Protestant) and are willing to provide care, countering the assumption that those of faith would all raise conscientious objections to service provision. CONCLUSIONS: The findings of this study are very encouraging for the development, implementation and delivery of local abortion care within HSC Trusts in Northern Ireland and should be of value in informing commissioners and providers about the design of a service model and its underpinning training programmes.

RESUMEN

PURPOSE: The aim of this study was to develop and test a new classification scale to describe looking behaviours (gaze fixations and gaze shifts) in relation to eye-pointing. METHODS: The Eye-pointing Classification Scale (EpCS) was developed and tested following established procedures for the construction and evaluation of equivalent scales, and involved 2 phases: Drawing on research literature, Phase 1 involved initial drafting of the scale through a series of multi-disciplinary group discussions; evaluation of the scale through a survey procedure, and subsequent expert group evaluation. Phase 2, was an examination of scale reliability and relationships between child characteristics and level of EpCS classification. RESULTS: In Phase 1, an initial draft of the scale was developed and then evaluated by 52 participants in 10 countries, leading to its refinement. Subsequent expert evaluation of content, style and structure indicated that no further refinement was required. In Phase 2, the scale achieved excellent levels of reliability in clinical testing. A significant relationship was identified between level of child motor ability and EpCS classification, and level of child language understanding and EpCS classification.Implications for rehabilitationNon-speaking children with severe bilateral cerebral palsy who have limited upper limb movement may communicate by using controlled looking behaviours to point to objects and people, referred to as eye-pointing.However, there is little consensus as to which looking behaviours represent eye-pointing and which do not.The Eye-pointing Classification Scale (EpCS) was developed to describe looking behaviours related to eye-pointing in this population of childrenThe EpCS provides a new robust tool for clinical management and research with children with cerebral palsy.

RESUMEN

There is a need to better understand key factors that impact sleep and circadian function for young adults of differing races and sexes. Sex and race are common factors contributing to disparities in health outcomes; however, the influence of these variables on sleep and circadian patterns for young adults are not well known. Multiple objective and self-report facets of sleep and circadian function were assessed (melatonin onset, actigraphy, and sleep diaries) in an ecological momentary assessment study of 150 emerging adults (Mage = 21.8 years; 58.7% female; 56% White, 22.7% Black, 21.3% Other ethnicity) at high or low risk for bipolar spectrum disorder (BSD). Controlling for BSD risk status, sex and race were significant predictors of objective and self-reported sleep and circadian rhythm measures. Males self-reported better sleep efficiency and exhibited later dim light melatonin onset phase than females, whereas females exhibited more actigraphy-measured sleep periods. White participants exhibited more actigraphy-measured total sleep time (TST), better sleep efficiency, and fewer sleep periods, and more self-reported TST and better sleep efficiency than Black participants. Our findings enhance the literature by utilizing robust measurement of sleep and circadian parameters to extend previous findings to a young adult sample at high or low risk for BSD.

RESUMEN

OBJECTIVE: Half of US children with autism spectrum disorder (ASD) have attempted to elope from adult supervision at least once, elevating their risk for serious injury/death. This study aimed to assess, in a sample of children with ASD aged 4 to 18 years who had previously wandered, whether electronic tracking device (ETD) use is associated with changes in the elopement behavior and household quality of life (QOL). METHODS: An anonymous, online questionnaire assessing elopement interventions, elopement behavior, household QOL, attitudes toward ETDs, and sociodemographics was distributed via US autism-related organizations to caregivers of children with ASD. Differences in retrospective estimates of elopement behavior and household QOL before ETD use and during ETD use were evaluated using Wilcoxon signed-rank tests. RESULTS: A total of 2563 participants completed the questionnaire; 1459 participants met the inclusion criteria. For the current (n = 361) and past (n = 96) ETD users, ETD use was associated with decreased frequency and duration of elopement and decreased risk for serious injury because of elopement (all p < 0.001). ETD use was similarly associated with improvements across all 5 measures of QOL. Among the past ETD users, reasons for discontinuation included device discomfort/fit (33.3%), burden of use (27.1%), and financial cost (14.6%). Among the non-ETD users (n = 1002), common barriers to ETD use were cost (47.5%) and lack of awareness of ETD technology (18.8%). CONCLUSION: Electronic tracking devices represent a promising technology to help safeguard the well-being of children with ASD while reducing the emotional toll that elopement imposes on families. Cost concerns, burden of use, and lack of awareness seem to limit the widespread adoption of ETDs.

RESUMEN

RituxiCAN-C4 combined an open-labeled randomized controlled trial (RCT) in 7 UK centers to assess whether rituximab could stabilize kidney function in patients with chronic rejection, with an exploratory analysis of how B cell-depletion influenced T cell anti-donor responses relative to outcome. Between January 2007 and March 2015, 59 recruits were enrolled after screening, 23 of whom consented to the embedded RCT. Recruitment was halted when in a pre-specified per protocol interim analysis, the RCT was discovered to be significantly underpowered. This report therefore focuses on the exploratory analysis, in which we confirmed that when B cells promoted CD4+ anti-donor IFNγ production assessed by ELISPOT, this associated with inferior clinical outcome; these patterns were inhibited by optimized immunosuppression but not rituximab. B cell suppression of IFNγ production, which associated with number of transitional B cells and correlated with slower declines in kidney function was abolished by rituximab, which depleted transitional B cells for prolonged periods. We conclude that in this patient population, optimized immunosuppression but not rituximab promotes anti-donor alloresponses associated with favorable outcomes. Clinical Trial Registration: Registered with EudraCT (2006-002330-38) and www.ClinicalTrials.gov, identifier: NCT00476164.
