RESUMO
Siglec-7 (sialic acid-binding immunoglobulin-like lectin 7) is a glycan-binding immune receptor that is emerging as a significant target of interest for cancer immunotherapy. The physiological ligands that bind Siglec-7, however, remain incompletely defined. In this study, we characterized the expression of Siglec-7 ligands on peripheral immune cell subsets and assessed whether Siglec-7 functionally regulates interactions between immune cells. We found that disialyl core 1 O-glycans are the major immune ligands for Siglec-7 and that these ligands are particularly highly expressed on naïve T-cells. Densely glycosylated sialomucins are the primary carriers of these glycans, in particular a glycoform of the cell-surface marker CD43. Biosynthesis of Siglec-7-binding glycans is dynamically controlled on different immune cell subsets through a genetic circuit involving the glycosyltransferase GCNT1. Siglec-7 blockade was found to increase activation of both primary T-cells and antigen-presenting dendritic cells in vitro, indicating that Siglec-7 binds T-cell glycans to regulate intraimmune signaling. Finally, we present evidence that Siglec-7 directly activates signaling pathways in T-cells, suggesting a new biological function for this receptor. These studies conclusively demonstrate the existence of a novel Siglec-7-mediated signaling axis that physiologically regulates T-cell activity. Going forward, our findings have significant implications for the design and implementation of therapies targeting immunoregulatory Siglec receptors.

This article explores the evolution of a novel approach designed to advance qualitative methods in cross-cultural health research. This methodology was developed by synthesising several research methods and involved in-depth stakeholder consultation with participants of a Pacific-based nursing and midwifery health leadership program. Many of these participants played a crucial role in creating, exploring and evaluating several research methods and implementing and evaluating this co-designed research methodology. Starting with a Participatory Action Research framework, the research methodology evolved as it was informed by the local Pacific methodologies (in particular Talanoa and Kakala frameworks), where researchers, co-researchers and participants alike, working from within their own collectivist/individualist paradigms, negotiated cultural differences. Finally, a methodological framework of 'best practice' for future health research methods was developed for use with capacity building research. The new methodology could provide a foundation for future co-designed cross-cultural research in collectivist cultures.

Prospective trials demonstrate that sentinel node (SN) biopsy after neo-adjuvant chemotherapy (NACT) has a significant false-negative rate (FNR) when only 1 or 2 SNs are removed. It is unknown whether this increased FNR correlates with an elevated risk of recurrence. Tumor Registry data at an NCI-Designated Comprehensive Cancer Center were reviewed from 2004 to 2018 for patients having a negative SN biopsy after NACT. Among 190 patients with histologically negative nodes after NACT having 1 (n = 42), 2 (n = 46), and ≥3 (n = 102) SNs, axillary recurrences occurred in 7.14%, 0%, and 1.96% (p = 0.09), breast recurrences occurred in 2.38%, 6.52%, and 0.98% (p = 0.12), and distance recurrences occurred in 16.67%, 8.70%, and 7.84% (p = 0.27), respectively. Time to first recurrence did not differ by SN count (p = 0.41). After adjustment for age, race, clinical stage, and receptor status, there were no differences in the rates of axillary (p = 0.26), breast (p = 0.44), or distance recurrence (p = 0.24) by numbers of SNs harvested. Median follow-up was 46.8 months. Despite higher post-NACT FNRs reported in randomized trials for patients having <3 sentinel nodes, recurrence rates were not significantly different for 1 versus 2 versus ≥3 SNs. This suggests that patients having 1 or 2 post-NACT SNs identified may not necessitate axillary dissection.

Multiple myeloma (MM) is a clonal plasma cell malignancy typically associated with the high and uniform expression of the CD38 transmembrane glycoprotein. Daratumumab is a humanized IgG1κ CD38 monoclonal antibody (MoAb) which has demonstrated impressive single agent activity even in relapsed refractory MM patients as well as strong synergy with other anti-MM drugs. Natural Killer (NK) cells are cytotoxic immune effector cells that mediate in vivo tumour immunosurveillance. NK cells also play an important role during MoAb therapy by inducing antibody dependent cellular cytotoxicity (ADCC) via their FcγRIII (CD16) receptor. Furthermore, 15% of the population express a naturally occurring variant of CD16 harbouring a single-point polymorphism (F158V). However, the contribution of NK cells to the efficacy of daratumumab remains debatable as clinical data clearly indicate the rapid depletion of CD38high peripheral blood NK cells in patients upon daratumumab administration. In contrast, CD38low peripheral blood NK cells have been shown to survive daratumumab mediated fratricide in vivo, while still retaining their potent anti-MM cytolytic effector functions ex vivo. Therefore, we hypothesize that transiently expressing the CD16F158V receptor using a "safe" mRNA electroporation-based approach on CD38low NK cells in combination with daratumumab could represent a novel therapeutic option for treatment of MM. In the present study, we investigate a NK cell line (KHYG-1), derived from a patient with aggressive NK cell leukemia, as a platform for generating CD38low NK cells expressing CD16F158V which can be administered as an "off-the-shelf" therapy to target both CD38high and CD38low tumour clones in patients receiving daratumumab.

BACKGROUND: Although treatment delays have been associated with survival impairment for invasive breast cancer, this has not been thoroughly investigated for ductal carcinoma in situ (DCIS). With trials underway to assess whether DCIS can remain unresected, this study was performed to determine whether longer times to surgery are associated with survival impairment or increased invasion. METHODS: A population-based study of prospectively collected national data derived from women with a clinical diagnosis of DCIS between 2004 and 2014 was conducted using the National Cancer Database. Overall survival (OS) and presence of invasion were assessed as functions of time by evaluating five intervals (≤ 30, 31-60, 61-90, 91-120, 121-365 days) between diagnosis and surgery. Subset analyses assessed those having pathologic DCIS versus invasive cancer on final pathology. RESULTS: Among 140,615 clinical DCIS patients, 123,947 had pathologic diagnosis of DCIS and 16,668 had invasive ductal carcinoma. For all patients, 5-year OS was 95.8% and unadjusted median delay from diagnosis to surgery was 38 days. With each delay interval increase, added relative risk of death was 7.4% (HR 1.07; 95% CI 1.05-1.10; P < 0.001). On final pathology, 5-year OS for noninvasive patients was 96.0% (95% CI 95.9-96.1%) versus 94.9% (95% CI 94.6-95.3%) for invasive patients. Increasing delay to surgery was an independent predictor of invasion (OR 1.13; 95% CI 1.11-1.15; P < 0.001). CONCLUSIONS: Despite excellent OS for invasive and noninvasive cohorts, invasion was seen more frequently as delay increased. This suggests that DCIS trials evaluating nonoperative management, which represents infinite delay, require long term follow up to ensure outcomes are not compromised.

BACKGROUND: Characterization of breast cancer phenotypes has improved our ability to predict breast cancer behavior. Triple-negative (TN) breast cancers have higher and earlier rates of distant events. It has been suggested that this behavior necessitates treating TNs faster than others, including use of neoadjuvant chemotherapy (NACT) if time to surgery is not rapid. METHODS: A review of women diagnosed with non-inflammatory, invasive breast cancer was conducted using the National Cancer Database for patients not having NACT, diagnosed between 2010 and 2014. Changes in overall survival due to delay were measured by phenotype. RESULTS: Overall, 351,087 patients met the inclusion criteria, including 36,505 (10.4%) TNs, 77.9% hormone receptor-positive (HR+) and 11.7% human epidermal growth factor receptor 2 (HER2)-enriched (HER2+). Phenotype, among other factors, was predictive of treatment delays. Adjusted median days from diagnosis to surgery and chemotherapy were 29.9, 31.6 and 31.5 (p< 0.001), and 72.7, 78.0 and 74.4 (p< 0.001) for TNs, HR+ and HER2+ cancers, respectively. After diagnosis, OS declined for all patients per month of preoperative delay (hazard ratio 1.104; p< 0.001). In models separating or combining surgery and chemotherapy, this survival decline did not vary by breast cancer phenotype (p > 0.3). CONCLUSIONS: Delays cause small but measurable effects overall, but the effect on survival does not differ among breast cancer phenotypes. Our data suggest that urgency between diagnosis and surgery or chemotherapy is similar for breast cancers of different subtypes. Although NACT is sometimes advocated solely to avoid treatment delays, this study does not suggest a greater surgical urgency for TNs compared with other breast cancer phenotypes.

OBJECTIVE: Perforate the expanded polytetrafluoroethylene membrane of the GORE® CARDIOFORM Septal Occluder (GSO) and GORE® CARDIOFORM ASD Occluder (GCA) after implantation. BACKGROUND: Percutaneous transseptal access to the left atrium is necessary for many structural and electrophysiological procedures. The potential need to access the left atrium may influence decision-making for patent foramen ovale or atrial septal defect closure. METHODS: Sixteen canines underwent implantation of equal number GSO or GCA devices. A transseptal crossing procedure was performed through the device 85 (±1) days postoccluder implantation. The crossing procedure was performed utilizing commercially available equipment: radiofrequency/SureFlex sheath and standard needle/Mullin's sheath. Progressive dilation of the perforation was performed to allow passage of a 12 French Mullin's sheath into the left atrium. RESULTS: Left atrial access was achieved in all cases. Postmortem analysis demonstrated passage through both occluder discs in all radiofrequency/SureFlex sheath cases (4 GSO, 4 GCA) and half of the standard needle/Mullin's sheath cases (3 GSO, 1 GCA). The remaining standard needle/Mullin's sheath cases demonstrated perforation through the right atrial disc but passage around the septal aspect of the left atrial disc, thus not perforating the left atrial disc. No acute embolic complications from the procedure were observed. CONCLUSIONS: Left atrial access may be achieved through the GSO or GCA devices after implantation and endothelialization. The combination of a radiofrequency needle and steerable sheath provides benefit over a standard needle and Mullin's sheath in accomplishing passage through both occluder discs.

PURPOSE: Breast conservation therapy (BCT) is standard for T1-T2 tumors, but early trials excluded breast cancers > 5 cm. This study was performed to assess patterns and outcomes of BCT for T3 tumors. METHODS: We reviewed the National Cancer Database (NCDB) for noninflammatory breast cancers > 5 cm, between 2004 and 2011 who underwent BCT or mastectomy (Mtx) with nodal evaluation. Patients with skin or chest wall involvement were excluded. Patients having clinical T3 tumors were analyzed to determine outcomes based upon presentation, with those having pathologic T3 tumors, subsequently assessed, irrespective of presentation. Overall survival (OS) was analyzed using multivariable Cox proportional hazards models, with adjusted survival curves estimated using inverse probability weighting. RESULTS: After exclusions, 37,268 patients remained. Median age and tumor size for BCT versus Mtx were 53 versus 54 years (p < 0.001) and 6.0 versus 6.7 cm (p < 0.001), respectively. Predictors of BCT included age, race, location, facility type, year of diagnosis, tumor size, grade, histology, nodes examined and positive, and administration of chemotherapy and radiotherapy. OS was similar between Mtx and BCT (p = 0.36). This held true when neoadjuvant chemotherapy patients were excluded (p = 0.39). BCT percentages declined over time (p < 0.001), while tumor sizes remained the same (p = 0.77). Median follow-up was 51.4 months. CONCLUSIONS: OS for patients with T3 breast cancers is similar whether patients received Mtx or BCT, confirming that tumor size should not be an absolute BCT exclusion. Declining use of BCT for tumors > 5 cm in younger patients may be accounted for by recent trends toward mastectomy.

Luciferase-based reporter assays are powerful tools for monitoring gene expression in cells because of their ultrasensitive detection capacity and wide dynamic range. Here we describe the characterization and use of a luciferase reporter enzyme derived from the marine copepod Metridia luciferase family, referred to as TurboLuc luciferase (TurboLuc). To develop TurboLuc, the wild-type luciferase was modified to decrease its size, increase brightness, slow luminescent signal decay, and provide for efficient intracellular expression. To determine the enzyme susceptibility to compound inhibition and judge the suitability of using of TurboLuc as a reporter in screening assays, purified TurboLuc enzyme was screened for inhibitors using two different compound libraries. No inhibitors of this enzyme were identified in a library representative of typical diverse low molecular weight (LMW) compounds using a purified TurboLuc enzyme assay supporting that such libraries will show very low interference with this enzyme. We were able to identify a few inhibitors from a purified natural product library which can serve as useful tools to validate assays using TurboLuc. In addition to the inhibitor profile for TurboLuc we describe the use of this reporter in cells employing miniaturized assay volumes within 1536-well plates. TurboLuc luciferase is the smallest luciferase reporter enzyme described to date (16 kDa), shows bright luminescence and low interference by LMW compounds, and therefore should provide an ideal reporter in assays applied to high-throughput screening.

Capture of highly volatile radioactive iodine is a promising application of metal-organic frameworks (MOFs), thanks to their high porosity with flexible chemical architecture. Specifically, strong charge-transfer binding of iodine to the framework enables efficient and selective iodine uptake as well as its long-term storage. As such, precise knowledge of the electronic structure of iodine is essential for a detailed modeling of the iodine sorption process, which will allow for rational design of iodophilic MOFs in the future. Here we probe the electronic structure of iodine in MOFs at variable iodine···framework interaction by Raman and optical absorption spectroscopy at high pressure ( P). The electronic structure of iodine in the straight channels of SBMOF-1 (Ca- sdb, sdb = 4,4'-sulfonyldibenzoate) is modified irreversibly at P > 3.4 GPa by charge transfer, marking a polymerization of iodine molecules into a 1D polyiodide chain. In contrast, iodine in the sinusoidal channels of SBMOF-3 (Cd- sdb) retains its molecular (I2) character up to at least 8.4 GPa. Such divergent high-pressure behavior of iodine in the MOFs with similar port size and chemistry illustrates adaptations of the electronic structure of iodine to channel topology and strength of the iodine···framework interaction, which can be used to tailor iodine-immobilizing MOFs.
RESUMO
AIMS AND OBJECTIVES: The aim of this study was to describe the effect that immersive simulation experiences and guided reflection can have on the undergraduate nurses' understanding of how stressful environments impact their emotions, performance and ability to implement safe administration of medications. BACKGROUND: Patient safety can be jeopardised if nurses are unsure of how to appropriately manage and respond to interruptions. Medication administration errors are a major patient safety issue and often occur as a consequence of ineffective interruption management. The skills associated with medication administration are most often taught to, and performed by, undergraduate nurses in a controlled environment. However, the clinical environment in which nurses are expected to administer medications is often highly stressed and nurses are frequently interrupted. DESIGN/METHODS: This study used role-play simulation and written reflections to facilitate deeper levels of student self-awareness. A qualitative approach was taken to explore students' understanding of the effects of interruptions on their ability to undertake safe medication administration. Convenience sampling of second-year undergraduate nursing students enrolled in a medical-surgical subject was used in this study. Data were obtained from 451:528 (85.42%) of those students and analysed using thematic analysis. RESULTS: Students reported increasing consciousness and the importance of reflection for evaluating performance and gaining self-awareness. They described self-awareness, effective communication, compassion and empathy as significant factors in facilitating self-efficacy and improved patient care outcomes. CONCLUSIONS: Following a role-play simulation experience, student nurses reported new knowledge and skill acquisition related to patient safety, and new awareness of the need for empathetic and compassionate care during medication administration. Practicing medication administration in realistic settings adds to current strategies that aim to reduce medication errors by allowing students to reflect on and in practice and develop strategies to ensure patient safety. RELEVANCE TO CLINICAL PRACTICE: Experiencing clinical scenarios within the safety of simulated environments, offers undergraduate student nurses an opportunity to reflect on practice to provide safer, more empathetic and compassionate care for patients in the future.

AIMS AND OBJECTIVES: To describe undergraduate student nurse responses to a simulated role-play experience focussing on managing interruptions during medication administration. BACKGROUND: Improving patient safety requires that we find creative and innovative methods of teaching medication administration to undergraduate nurses in real-world conditions. Nurses are responsible for the majority of medication administrations in health care. Incidents and errors associated with medications are a significant patient safety issue and often occur as a result of interruptions. Undergraduate nursing students are generally taught medication administration skills in a calm and uninterrupted simulated environment. However, in the clinical environment medication administration is challenged by multiple interruptions. DESIGN/METHODS: A qualitative study using convenience sampling was used to examine student perceptions of a simulated role-play experience. Data were collected from 451 of a possible 528 student written reflective responses and subject to thematic analysis. RESULTS: Students reported an increased understanding of the impacts of interruptions while administering medications and an improved awareness of how to manage disruptions. This study reports on one of three emergent themes: "Calm to chaos: engaging with the complex nature of clinical practice." CONCLUSIONS: Interrupting medication administration in realistic and safe settings facilitates awareness, allows for students to begin to develop management strategies in relation to interruption and increases their confidence. Students were given the opportunity to consolidate and integrate prior and new knowledge and skills through this role-play simulation.

BACKGROUND: Although breast conservation therapy (BCT) is standard for breast cancer treatment, patients with tumors measuring >5 cm have been excluded from clinical trials. Nevertheless, only a few small retrospective series to date have compared BCT with mastectomy for tumors measuring >5 cm. The current study was performed to determine whether survival is equivalent for BCT versus mastectomy using a large national data set. METHODS: Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked cases were identified for patients aged ≥ 66 years undergoing breast conservation for invasive, noninflammatory, nonmetastatic breast cancer between 1992 and 2009. Propensity score-based adjustment was used to account for demographics and tumor and treatment factors. RESULTS: A total of 5685 patients with tumors measuring >5.0 cm underwent breast surgery, with 15.6% receiving BCT. Mean ages of the patients and tumor sizes were similar. Predictors of BCT included neoadjuvant chemotherapy and postoperative radiotherapy use, higher income, breast cancer as a first malignancy, and a higher Charlson Comorbidity Index. Predictors of mastectomy included younger age, nonductal histology, higher grade, numbers of lymph nodes examined and found to be positive, American Joint Committee on Cancer stage III disease, postoperative chemotherapy use, and residential region of the country. Adjusted overall and breast cancer-specific survival were not different between patients treated with BCT and mastectomy (hazard ratio, 0.934; 95% confidence interval, 0.791-1.103 [P = .419] for overall survival; and subdistribution hazard ratio, 1.042; 95% confidence interval, 0.793-1.369 [P = .769] for breast cancer-specific survival), with each improving over time. The median follow-up was 7.0 years. CONCLUSIONS: For Medicare patients with tumors measuring >5 cm, survival is similar between those treated with BCT and mastectomy as for patients with smaller primary tumors. Despite exclusion from randomized trials, BCT may remain an option for patients with larger tumors when deemed clinically and cosmetically amenable to surgical resection.

AIM: To explore the perceptions of early career nursing academics on leadership in academia. BACKGROUND: There is growing emphasis on leadership capacity building across all domains of nursing. However, there is limited evidence on leadership capacity in early career academics. This study tested an intervention to develop leadership capacity amongst early career nursing academics in two Australian universities. METHODS: A sequential mixed methods design, using online surveys and semi-structured interviews, was used to collect data. RESULTS: Twenty-three early career nursing academics participated. Most had experience of formal leadership roles and were aware of its importance to them as they developed their academic careers. Participants were able to discuss their own views of themselves as leaders; their perceptions of their own needs for leadership development, and ways in which they could seek to develop further as leaders. CONCLUSION: There is a need to provide initial and ongoing opportunities for leadership development amongst nurse academics. These opportunities should be contextualised and recognise factors such as gender, and the effects of structural oppression. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse academics are involved in the preparation of the next generation of clinical leaders and it is imperative that they are able to articulate a clear view of leadership.

AIMS: This study aimed to compare the findings of the quality of nursing doctoral education survey across seven countries and discuss the strategic directions for improving quality. BACKGROUND: No comparative evaluation of global quality of nursing doctoral education has been reported to date despite the rapid increase in the number of nursing doctoral programmes. DESIGN: A descriptive, cross-country, comparative design was employed. METHODS: Data were collected from 2007-2010 from nursing schools in seven countries: Australia, Japan, Korea, South Africa, Thailand, UK and USA. An online questionnaire was used to evaluate quality of nursing doctoral education except for Japan, where a paper version was used. Korea and South Africa used e-mails quality of nursing doctoral education was evaluated using four domains: Programme, Faculty (referring to academic staff), Resource and Evaluation. Descriptive statistics, correlational and ordinal logistic regression were employed. RESULTS: A total of 105 deans/schools, 414 faculty and 1149 students/graduates participated. The perceptions of faculty and students/graduates about the quality of nursing doctoral education across the seven countries were mostly favourable on all four domains. The faculty domain score had the largest estimated coefficient for relative importance. As the overall quality level of doctoral education rose from fair to good, the resource domain showed an increased effect. CONCLUSIONS: Both faculty and students/graduates groups rated the overall quality of nursing doctoral education favourably. The faculty domain had the greatest importance for quality, followed by the programme domain. However, the importance of the resource domain gained significance as the overall quality of nursing doctoral education increased, indicating the needs for more attention to resources if the quality of nursing doctoral education is to improve.

AIMS AND OBJECTIVES: To explore how aesthetic leadership is embodied by clinical leaders in the nursing workplace. BACKGROUND: A number of different leadership styles have been developed, theorised and applied to the nursing workforce over the years. Many of these styles lack an explicit moral dimension in their identified leader attributes, due to a shift in theorising of leadership to focus on the impact of leader traits on followers. It is timely to look at aesthetic leadership, with its explicit moral dimension, as a way of improving outcomes for nurses, patients and health care organisations. DESIGN: Qualitative design, using conversation-style interviews with experienced registered nurses in designated clinical leadership roles. METHODS: Twelve experienced registered nurses who worked in designated clinical leadership roles participated in an individual, digitally recorded, semi-structured conversation-style interview. Narrative data were transcribed and subject to thematic analysis. FINDINGS: Three main themes emerged: 'True to their beliefs': embodying principled practice; 'Not all policies fit every patient': ethical leadership in ambiguous situations; and 'Being open to people's concerns': providing fair and just solutions. A strong moral compass shaped and guided participants' day-to-day clinical leadership activities. CONCLUSIONS: Participants provided a rich narrative on how aesthetic leadership is embodied in the clinical nursing setting. It was evident that their clinical leadership is shaped and guided by a strong moral compass. By incorporating into their practice an aesthetic world-view with its strong moral purpose, participants in this study have shown how aesthetic leadership can enhance the clinical nursing workplace. RELEVANCE TO CLINICAL PRACTICE: Nurses in the clinical setting value clinical leaders who embrace and operate with a strong moral compass. Aesthetic leadership, with its explicit strong moral purpose, offers a way of incorporating morality into clinical leadership in the nursing workplace.

AIMS AND OBJECTIVES: This paper reports the results of an online descriptive survey that sought to determine nurses' perceptions of aesthetic leadership among clinical leaders in nursing. BACKGROUND: Clinical leadership has been identified as an essential component to ensuring the delivery of safe, high-quality health care. Leadership has been increasingly linked in the literature to aesthetics. However, little consideration has been given to aesthetics in relation to clinical leadership in nursing. DESIGN: A mixed-method, online descriptive survey. METHODS: Participants were recruited via e-learning platforms and social media. A total of 66 surveys were completed, including 31 written accounts of aesthetic leadership in practice. RESULTS: Aesthetic leadership characteristics in clinical leaders most valued are support, communication and the approach taken to colleagues. Taking risks and challenging processes were least likely to be evident among effective clinical leaders. CONCLUSION: Aesthetic leadership is multi-dimensional and a style of leadership to positively influence the clinical workplace. Support, effective communication and taking into consideration the feelings of colleagues are important dimensions of aesthetic leadership. RELEVANCE TO CLINICAL PRACTICE: Aesthetic leadership represents a way for clinical leaders to create and sustain a calm and positive clinical workplace.

AIMS AND OBJECTIVES: To explore how clinical leaders enact aesthetic leadership in clinical nursing workplaces. BACKGROUND: Clinical leadership is heralded as vital for safe and effective nursing. Different leadership styles have been applied to the clinical nursing workplace over recent years. Many of these styles lack an explicit moral dimension, instead focusing on leader qualities and developing leader competence around team building, quality and safety. Aesthetic leadership, with its explicit moral dimension, could enhance clinical leadership effectiveness and improve nursing workplaces. How aesthetic leadership is enacted in clinical nursing settings requires exploration. DESIGN: A qualitative design, employing conversation-style interviews with experienced registered nurses and written responses gathered from an online descriptive survey. METHODS: Narrative data were gathered from interviews with 12 registered nurses and written accounts from 31 nurses who responded to an online survey. Together, transcribed interview data and the written accounts were subject to thematic analysis. RESULTS: Three main themes emerged: Leading by example: 'be seen in the clinical area'; Leading with composure: 'a sense of calm in a hideous shift'; and Leading through nursing values: 'create an environment just by your being'. CONCLUSIONS: Aesthetic leadership was shown to enhance clinical leadership activities in the nursing workplace. The capacity for clinical leaders to be self-reflective can positively influence the nursing workplace. It was apparent that clinical leader effectiveness can be enhanced with nursing values underpinning leadership activities and by being a visible, composed role model in the clinical workplace. RELEVANCE TO CLINICAL PRACTICE: Aesthetic leadership can enhance clinical nursing workplaces with its explicit moral purpose and strong link to nursing values. Clinical leaders who incorporate these attributes with being a visible, composed role model have the capacity to improve the working lives of nurses across a range of clinical settings.
