RESUMO
A novel HPLC method was developed and validated to determine radiochemical identity, radiochemical purity and chemical purity for the analysis of O-(2-[18F]fluoroethyl-l-tyrosine ([18F]FET). In this method, an analytical Phenomenex Gemini C18 column was used with an isocratic eluent of 7 % ethanol and 93 % 50 mM potassium phosphate buffer (pH = 6.9). The flow rate was 1.0 mL/min and the injection volume was 10 µL. A photo-diode array detector set at 220 nm was used for UV mass detection and a single channel, high sensitivity radiation detector was used. The method validation assays including specificity, linearity, precision, accuracy, and robustness were evaluated. Results show that the method was suitable for qualitative and quantitative determination of radiochemical and chemical purity of [18F]FET. This system has been routinely used for the analysis of more than 120 batches of [18F]FET with radiochemical yield 23.7 ± 6 % (no decay corrected) and molar activity 593 ± 284 GBq/µmole in our facility to support human use.
RESUMO
Fire shapes animal communities by altering resource availability and species interactions, including between predators and prey. In Australia, there is particular concern that two highly damaging invasive predators, the feral cat (Felis catus) and European red fox (Vulpes vulpes), increase their activity in recently burnt areas and exert greater predation pressure on the native prey due to their increased exposure. We tested how prescribed fire occurrence and extent, along with fire history, vegetation, topography, and distance to anthropogenic features (towns and farms), affected the activity (detection frequency) of cats, foxes, and the native mammal community in south-eastern Australia. We used camera traps to quantify mammal activity before and after a prescribed burn and statistically tested how the fire interacted with these habitat variables to affect mammal activity. We found little evidence that the prescribed fire influenced the activity of cats and foxes and no evidence of an effect on kangaroo or small mammal (<800 g) activity. Medium-sized mammals (800-2000 g) were negatively associated with prescribed fire extent, suggesting that prescribed fire has a negative impact on these species in the short term. The lack of a clear activity increase from cats and foxes is likely a positive outcome from a fire management perspective. However, we highlight that their response is likely dependent upon factors like fire size, severity, and prey availability. Future experiments should incorporate GPS-trackers to record fine-scale movements of cats and foxes in temperate ecosystems immediately before and after prescribed fire to best inform management within protected areas.
RESUMO
BACKGROUND: Workplace violence, including violent, intimidating, and disruptive acts, commonly occurs in healthcare settings. Type 2 workplace violence in nursing refers to patient/visitor behaviors directed toward clinicians, contributing to physical and psychological harm. Nurse victims often do not report these events to employers or law enforcement, making it challenging to address workplace violence. OBJECTIVES: Our research examined nurse reactions to Type 2 workplace violence by identifying what behaviors they perceived as aggressive and reportable. Specific aims included: 1) developing and testing video vignettes to portray realistic patient aggression scenarios; 2) identifying nurse understandings of aggressive events that prompt affective reactions, and; 3) examining clinical characteristics related to the nurse victim's likelihood to report. DESIGN: Through a sequential mixed-methods design, we qualitatively developed novel video vignettes portraying Type 2 workplace violence to experimentally examine how nurses interpreted them within a quantitative repeated measures survey. METHODS: Two expert nurse research panels (nâ¯=â¯10) created five vignettes, from which nurses (nâ¯=â¯282) completed a survey with 1382 unique responses. Analyses included descriptive statistics and repeated measures ANOVA/regression models. RESULTS: Video vignettes realistically portrayed workplace violence events, eliciting negative emotional responses among nurses that increased in magnitude with statistical significance as the level of displayed aggression escalated. Statistically significant factors influencing nurse reporting of workplace violence included; 1) the level of aggression displayed by the patient; 2) the level of harm received by the nurse; 3) whether the nurse felt the patient's actions were intentional, and; 4) the nurse's perceived frequency of exposure to workplace violence. CONCLUSIONS: Results suggested that nurse victims of Type 2 workplace violence experience depression, anger, fear, and anxiety, which may contribute to long-term mental health consequences. Findings also identified factors related to nurse reporting behaviors, which may help mitigate workplace violence in healthcare settings by informing research and promoting workplace practices that encourage reporting and safety. REGISTRATION: Not registered. TWEETABLE ABSTRACT: Nurse reactions to workplace violence: Video vignettes reveal escalating aggression's impact on reporting. #EndNurseAbuse #WorkplaceViolence.

The aim of this qualitative study was to identify nursing processes of care that help keep patients successfully on home hemodialysis (HHD). A qualitative descriptive approach using appreciative inquiry was used as the framework for data collection and analysis. Four focus groups were held with HHD nursing teams in the Province of Ontario, Canada. Results suggest that successful HHD teams have highly performing nurses who work cohesively as a team, and have consistent structures and processes in place for patient education and follow up. A culture of success has the potential to keep patients successfully on HHD, improve nurse job satisfaction, and retain highly functioning and specialized nursing staff. Quality improvement initiatives aimed at improving rates of HHD are important given the benefits to patients of HHD as a treatment modality.

Caring for people with chronic kidney disease, let alone during a pandemic, can place nurses at risk for burnout. This study explored the effects of the Mindful Self-Compassion (MSC) 8-week training on nephrology nurses' levels of self-compassion, burnout, and resilience. Twelve nurses participated. Surveys were completed before, immediately after, and three months after training. A focus group was also conducted. Results demonstrated in creased levels of self-compassion, mindfulness, and resilience while levels of burnout decreased. The central qualitative theme was enhanced resilience. Subthemes were creating a community of support, awareness and discovery, and the mastery of the techniques. The MSC training was an effective intervention to build essential skills for maintaining a healthy workforce. Implementation of such training programs within the health care environment are highly encouraged.

An important factor for quality and safety in patient care is an environment in which quality and safety are prioritized and embedded into the culture. Quality improvement (QI) methods can be complex, with some intensive resources required and specific methods employed. However, all staff can be involved in QI if the problem is approached with curiosity and the process is kept simple, with a consistent goal of improving practices. The purpose of this article is to highlight some simple but effective QI methods authored by all-star nephrology nurses that can be easily applied by teams in various settings with minimal resources.

AIM: To establish the current state of the science about why nurses do or do not report being the victim of patient aggression, a form of type II workplace violence. This aim includes identifying and analysing current gaps in the literature. BACKGROUND: It is increasingly more common for patients to instigate aggressive acts towards nurses, leading to significant consequences. Nursing victims often do not report acts of patient aggression to others, making it difficult for health care leaders and researchers to address this challenge. EVALUATION: The review process involved searching five databases, using the PRISMA framework to reduce 355 records to 65 sources for review and synthesis. KEY ISSUES: The findings of this review highlight key takeaways about why nursing victims do not report episodes of patient aggression, which include their fears, attitudes and abilities related to reporting; and their perspective of the patient aggression event. Workplace environments are central to most of these factors, emphasizing the importance of nursing and other health care leaders to put systems in place that promote nurse reporting behaviours. CONCLUSIONS: Patient aggression is a widespread problem with severe consequences. Review findings can inform future research while having practical relevance for health care leaders. IMPLICATIONS FOR NURSING MANAGEMENT: Health care leaders need to consider how workplace structures, practices, and cultures can encourage or stifle nurse reporting behaviours. By understanding nurse reporting behaviours, processes can be developed to promote nursing victim reporting and deter patient aggression.

Importance: Vaccine-derived and wild-type rubella virus (RuV) has been identified within granulomas in patients with inborn errors of immunity, but has not been described in granulomas of healthy adults. Objective: To determine the association between RuV and atypical granulomatous inflammation in immune-competent adults. Design, Setting, and Participants: This case series, conducted in US academic dermatology clinics from January 2019 to January 2021, investigated the presence of RuV in skin specimens using RuV immunofluorescent staining of paraffin-embedded tissue sections, real-time reverse-transcription polymerase chain reaction, whole-genome sequencing with phylogenetic analyses, and cell culture by the US Centers for Disease Control and Prevention. Rubella immunoglobulin G, immunoglobulin M enzyme-linked immunoassay, and viral neutralization assays were performed for the sera of immunocompetent individuals with treatment refractory cutaneous granulomas and histopathology demonstrating atypical palisaded and necrotizing granulomas. Clinical immune evaluation was performed. Main Outcomes and Measures: Identification, genotyping, and culture of vaccine-derived and wild-type RuV within granulomatous dermatitis of otherwise clinically immune competent adults. Results: Of the 4 total immunocompetent participants, 3 (75%) were women, and the mean (range) age was 61.5 (49.0-73.0) years. The RuV capsid protein was detected by immunohistochemistry in cutaneous granulomas. The presence of RuV RNA was confirmed by real-time reverse-transcription polymerase chain reaction in fresh-frozen skin biopsies and whole-genome sequencing. Phylogenetic analysis of the RuV sequences showed vaccine-derived RuV in 3 cases and wild-type RuV in 1. Live RuV was recovered from the affected skin in 2 participants. Immunology workup results demonstrated no primary immune deficiencies. Conclusions and Relevance: The case series study results suggest that RuV (vaccine derived and wild type) can persist for years in cutaneous granulomas in clinically immunocompetent adults and is associated with atypical (palisaded and necrotizing type) chronic cutaneous granulomas. These findings represent a potential paradigm shift in the evaluation, workup, and management of atypical granulomatous dermatitis and raises questions regarding the potential transmissibility of persistent live RuV.

BACKGROUND: The novel human coronavirus (SARS-CoV-2) shows neurotropism and systemically affects the central nervous system (CNS). Cognitive deficits have been indeed reported as both short- and long-term sequelae of SARS-CoV-2 infection. However, the association between these disturbances and background/disease-related clinical features remains elusive. This work aimed at exploring how post-infective cognitive status relates to clinical/treatment outcomes by controlling for premorbid/current risk factors for cognitive deficits. METHODS: Cognitive measures (Mini-Mental State Examination, MMSE) of N=152 COVID-19 patient were retrospectively assessed in relation to disease severity, intensive care unit (ICU) admission, steroidal treatment, and occurrence of other viral/bacterial infections by controlling for remote/recent/COVID-19-related risk factors for cognitive deficits (at-risk vs. not-at-risk: Neuro+ vs. Neuro-). RESULTS: Descriptively, impaired MMSE performances were highly prevalent in mild-to-moderate patients (26.3%). ICU-admitted patients made less errors (p=.021) on the MMSE than those not admitted when partialling out risk factors and age-the latter negatively influencing performances. When addressing Neuro- patients only, steroidal treatment appears to improve MMSE scores among those suffering from other infections (p=.025). DISCUSSION: Cognitive sequelae of COVID-19 are likely to arise from a complex interplay between background/clinical premorbid features and disease-related/interventional procedures and outcomes. Mild-to-moderate patients requiring assistive ventilation who however are not admitted to an ICU are more likely to suffer from cognitive deficits-despite their etiology remaining elusive.

The effectiveness of holistic neuropsychological rehabilitation for people with acquired brain injury has previously been demonstrated by means of standardized and routinely administered outcome measures. However, the most important outcomes from the perspective of former clients are largely unknown. This study explored the experience of participating in a holistic neuropsychological rehabilitation programme by conducting three focus groups with twelve former clients who had sustained a brain injury. Data were transcribed verbatim and analysed using thematic analysis. "It is an ongoing process" emerged as the overarching theme for the experience of recovery from brain injury. Four subthemes, or phases, were identified. Participants went through (1) a phase of confrontation, after which they (2) trained their skills and strategies, and (3) experimented with these in daily life. In the end, clients reached a phase of (4) coming to terms with their injury. Participants described increased levels of self-esteem, sense of competence, and adaptation as the most important outcomes of the programme, as these factors helped them regain a sense of identity. The results indicate that including these factors in outcome evaluations of complex interventions after brain injury may be important as they appear essential for capturing the client's perspective on change.

BACKGROUND: Calciphylaxis is a debilitating dermatological condition associated with high rates of morbidity and mortality. Palliative care offers a multidisciplinary approach to addressing symptoms and goals of care in patients with serious medical diagnoses. Involvement of palliative services for calciphylaxis is infrequently reported in the literature. The purpose of this report is to assess rates of palliative and pain consultation for patients with calciphylaxis. METHODS: This is a comprehensive, single-institution retrospective chart review of 121 eligible patients with a diagnosis of calciphylaxis treated at Mayo Clinic in Rochester, Minnesota, from 1999 to 2016. Inclusion criteria were an indisputable diagnosis of calciphylaxis based on clinical, histopathologic, and radiographic features. One hundred twenty-one patients met inclusion criteria. RESULTS: Fifty-one patients (42%) received either a palliative (n = 15) or pain (n = 20) consultation, or both (n = 16). Patients with a palliative care consultation were younger compared with those without (mean ages 57 vs. 62 years, P = 0.046). In 104 patients (86%), psychiatric symptoms were not assessed. CONCLUSIONS: In this cohort of patients with calciphylaxis, the majority do not receive palliative and pain care consultations. Psychiatric complications are inconsistently addressed. These observations highlight practice gaps in the care of patients with calciphylaxis.

A training and coaching team embarked on a training and technical assistance program evaluation project to examine the development of a tool used to determine the impact of training on staff and families serving youth with behavioral health challenges and their families. The training evaluation project centered on the development of a tool to examine the impact of training on trainee attitudes. The current article provides an overview of the development of the Nurtured Heart Approach® (NHA) Questionnaire to help support training and technical assistance implementation efforts by nursing and other trainers interested in best practice approaches to empower youth with behavioral health challenges. The questionnaire was found to be internally consistent and to have relatively stable, empirically derived factors consistent with the NHA model, but differing somewhat from the theoretically derived "Stands," or areas of emphasis. The questionnaire is sensitive to changes in attitude resulting from the NHA training. Therefore, it would a viable, practical instrument to test staff acquisition of NHA-related attitudes.

BACKGROUND: Measuring clinical outcomes in prelicensure students is desired by key stakeholders but is fraught with challenges. There are currently no standardized, psychometrically validated clinical-outcome measures available for prelicensure nursing programs, requiring each program to design its own measures. METHOD: We conducted a review of the potential antecedents of this gap, as well as models for standardized clinical outcome measures and recommendations from within health-professions education. RESULTS: There are benefits to pursuing a standardized clinical outcome tool, including an improved student learning experience and unifying our communication regarding graduate nurse preparation to valued stakeholders. CONCLUSION: Nursing education has a unique opportunity to emulate our colleagues in medicine and pharmacy by working at the national level to create a standardized tool using current psychometric methods for development and validation.

INTRODUCTION: Pyoderma gangrenosum (PG) is a relatively uncommon necrotizing and ulcerative cutaneous disorder. It is often associated with a systemic inflammatory disease but may also present following trauma to the skin due to pathergy. Given its rare occurrence and nonspecific histology, PG is primarily a diagnosis of exclusion, which often results in delayed treatment. Very few cases of PG following autologous breast reconstruction have been reported in the literature, particularly in the absence of systemic disease. CASE REPORT: Presented is the case of a 62-year-old female with a history of ductal carcinoma in situ who underwent a left breast mastectomy with immediate deep inferior epigastric perforator flap breast reconstruction complicated by fever and leukocytosis as well as erythema, edema, and bullae involving the mastectomy flaps. Initially, necrotizing soft-tissue infection was suspected, and 2 debridements were performed. A diagnosis of PG was made on postoperative day 7, and the patient responded favorably to high-dose prednisone. Reconstruction was performed with a bilayer wound matrix and delayed skin grafting. Despite significant loss of mastectomy skin flap, the free flap was preserved. CONCLUSIONS: Although PG is a rare complication, it should be considered in the differential diagnosis for patients with atypical presentation of infection following breast reconstruction, even in the absence of systemic inflammatory disease. Early diagnosis and multidisciplinary management may prevent unnecessary surgical intervention and enable flap preservation. Furthermore, bilayer wound matrix placement may be useful as an intermediate reconstruction to determine if it is safe to proceed with skin grafting to avoid further pathergy. The findings in this case suggest that final reconstruction may be safely performed sooner than noted in the literature.

BACKGROUND: Knowledge about nursing student attitudes toward patients with cancer after an educational intervention and mentoring support is limited. This review examined the literature on this topic. OBJECTIVE: This integrative review aims to explore the literature on the experiences of students who participate in an oncology elective or educational course on cancer and their attitudes toward cancer. METHODS: A comprehensive search was conducted using PubMed, CINAHL, and MEDLINE databases. Each study was systematically assessed. An evidence table was completed to identify the key aspects of each study that was reviewed. RESULTS: There is insufficient information on the impact of nursing student education on the attitudes and skills of nursing students caring for patients with cancer. An integrative review was completed on the impact of education and mentoring for nursing students on cancer care, which yielded 10 studies that were reviewed. These studies indicate that educational intervention and mentoring improve the confidence and ability of nursing students to care for patients with cancer. CONCLUSIONS: Student nurses need to be armed with knowledge, skills, and positive attitudes while caring for patients with cancer. Nursing students perform best when they have accurate information, positive role models, and mentoring by experienced oncology professionals, to support proficiency in caring for patients with cancer. The lack of knowledge of nursing students in the areas of cancer care, treatment, and patient support requires additional education and research to promote expertise and positive attitudes toward cancer and treating patients with cancer. This will support nursing students' ability to care for patients with cancer as well as develop future educational interventions to shape nursing student attitude and knowledge. This integrative review also identifies the positive impact on the attitudes of other health care professionals who have received training or education on cancer.
RESUMO
Nephrology nurses are not immune to the effects of a stressful work environment. As a result, their emotional and psychological health can be at risk. In addition, there has been unprecedented stress and uncertainty working as nephrology nurses during the pandemic. These stressors can have negative effects on nurses' health, resulting in burnout and/or compassion fatigue, which can lead to nurses leaving nephrology or the nursing profession. Mindfulness has been suggested as a strategy to mitigate work-related stressors and build a more resilient workforce. Our experience suggests that combining self-compassion practices with mindfulness is also effective. Mindfulness may be beneficial for nephrology nurses, but its use does not negate the need for organizations to address the structural system issues that also contribute to burnout.

IMPORTANCE: Immunodeficiency-related, vaccine-derived rubella virus (RuV) as an antigenic trigger of cutaneous and visceral granulomas is a rare, recently described phenomenon in children and young adults treated with immunosuppressant agents. OBJECTIVE: To perform a comprehensive clinical, histologic, immunologic, molecular, and genomic evaluation to elucidate the potential cause of an adult patient's atypical cutaneous granulomas. DESIGN, SETTING, AND PARTICIPANTS: A prospective evaluation of skin biopsies, nasopharyngeal swabs, and serum samples submitted to the Centers for Disease Control and Prevention was conducted to assess for RuV using real-time reverse-transcriptase polymerase chain reaction (RT-PCR) and viral genomic sequencing. The samples were obtained from a man in his 70s with extensive cutaneous granulomas mimicking both cutaneous sarcoidosis (clinically) and CD8+ granulomatous cutaneous T-cell lymphoma (histopathologically). The study was conducted from September 2019 to February 2021. MAIN OUTCOMES AND MEASURES: Identification and genotyping of a novel immunodeficiency-related RuV-associated granulomatous dermatitis. RESULTS: Immunohistochemistry for RuV capsid protein and RT-PCR testing for RuV RNA revealed RuV in 4 discrete skin biopsies from different body sites. In addition, RuV RNA was detected in the patient's nasopharyngeal swabs by RT-PCR. The full viral genome was sequenced from the patient's skin biopsy (RVs/Philadelphia.PA.USA/46.19/GR, GenBank Accession #MT249313). The patient was ultimately diagnosed with a novel RuV-associated granulomatous dermatitis. CONCLUSIONS AND RELEVANCE: The findings of this study suggest that clinicians and pathologists may consider RuV-associated granulomatous dermatitis during evaluation of a patient because it might have implications for the diagnosis of cutaneous sarcoidosis, with RuV serving as a potential antigenic trigger, and for the diagnosis of granulomatous cutaneous T-cell lymphoma, with histopathologic features that may prompt an evaluation for immunodeficiency and/or RuV.
