Participation in staff engagement campaigns at large healthcare organisations: a focus group study.

INTRODUCTION: Healthcare organisations work better with an engaged workforce, and staff-engagement campaigns offer a method to build this engagement. Leeds Teaching Hospitals NHS Trust (LTHT), one of the UK's largest Trusts, provides an example of where an organisation-wide engagement intervention has been used in a healthcare setting. This study aimed to understand why staff participate, or do not participate, in staff-engagement campaigns, supporting healthcare leaders to increase participation in future campaigns. METHODS: Scenario-based focus groups were carried out across five different organisational units within LTHT. The data from these were transcribed, coded and analysed using reflective thematic analysis. RESULTS: Participation in staff-engagement campaigns is dependent on campaign awareness, staff perceptions of the campaign and the practicalities associated with participation. Perceptions of the campaign are further subdivided into the campaign's perceived effectiveness, purpose and relevance. CONCLUSIONS: Staff engagement was a powerful driver of participation, which presents a conundrum: how do you encourage participation in staff-engagement campaigns, if engagement is a prerequisite for participation? The answer lies in taking advantage of organisational belongingness and visible leadership, supported by communications that take control of the narrative around the campaign. Behavioural science models may guide leaders across the organisation in mapping where these approaches can have the greatest impact within their existing spheres of influence. Further, considering inequalities around participation across different groups may help target action to the areas of greatest need. Accordingly, the research provides pragmatic guidance for leaders in thinking about how to use staff-engagement campaigns more effectively.

Baeckea frutescens L. Promotes wound healing by upregulating expression of TGF-ß, IL-1 ß, VEGF and MMP-2.

Baeckea frutescens L. has been traditionally used for treating snakebites and is known to possess antifebrile and hemostatic properties. These properties are closely related to wound healing. This study aimed to evaluate the wound healing properties of B. frutescens leaves extract (BFLE) in vitro and in vivo. The in vitro study focused on proliferation, migration, and expression of TGF-ß, IL-1ß, VEGF, and MMP-2 genes and proteins. The in vivo study included excisional wound healing, histology, and tensile strength studies. The ethanolic extract of B. frutescens (BFLE) was tested for its effects on proliferation and migration using keratinocytes (HaCaT) and fibroblasts (BJ) cells. Gene and protein expression related to wound healing were analyzed using real-time PCR and Western blot assays. The wound healing properties of BFLE were evaluated in vivo using Wistar albino rats, focusing on excisional wound healing, histology, and tensile strength studies. The BFLE displayed significant proliferative and migratory effects on keratinocytes and fibroblasts cells, while upregulating the expression of TGF-ß, IL-1ß, VEGF, and MMP-2 genes and proteins. BFLE also exhibited significant wound healing effects on Wistar albino rats' excisional wounds and improved the overall tensile strength. The results suggest that BFLE has strong wound healing properties, as demonstrated by its ability to increase keratinocytes and fibroblasts proliferation and migration, upregulate genes and proteins involved in the wound healing process, and improve wound healing rates and tensile strength. The findings of this study provide important insights into the potential use of B. frutescens as a natural wound healing agent.

Analysis of 20 Years of Ethics Consultations at a U.S. Children's Hospital.

AbstractEmpirical studies of pediatric clinical ethics cases are scant in the biomedical and bioethics literature. In this study, more than 100 detailed records of clinical ethics consultations spanning from 2000 to 2020 at a moderately sized U.S. Mid-Atlantic children's hospital were abstracted and analyzed. Findings of the analysis were generally consistent with other studies in pediatric clinical ethics, with additional insight into aspects of moral distress associated with cases, family engagement with consultations, and other characteristics of interest also documented. Over the 20-year time frame, ethics consults were completed on average twice a year, with a detectable upward trend. Consultations were requested across the spectrum of services and units within the hospital, with critical care environments represented most frequently and genetic and neurological conditions being the most common primary diagnoses. Ethical analysis most commonly related to questions around the principles of autonomy and beneficence.

Impact of Humidification Modality on Incidence of Endotracheal Tube Occlusion in COVID-19 Patients.

Background: Endotracheal tube (ETT) occlusion is reported at a higher frequency among coronavirus disease-2019 (COVID-19) patients. Prior to the COVID-19 pandemic, literature examining patient and ventilator characteristics, including humidification, as etiologies of ETT occlusion yielded mixed results. Our study examines the relationship of humidification modality with ETT occlusion in COVID-19 patients undergoing invasive mechanical ventilation (IMV). Methods: We conducted a retrospective chart review of COVID-19 patients requiring IMV at a tertiary care center in New York from April 2020 to April 2021. Teleflex Neptune heated wire heated humidification (HH) and hygroscopic Intersurgical FiltaTherm and Sunmed Ballard 1500 heat and moisture exchangers (HME) were used. Episodes of ETT occlusion were recorded. Univariate and multivariable logistic regression models were used to investigate the relationship between humidification modality and the occurrence of ETT occlusion. Findings: A total of 201 eligible patients were identified. Teleflex HH was utilized in 50.2% of the population and the others Intersurgical and Sunmed HME devices. Median age was 62 years and 78.6% of patients had at least one medical comorbidity. Precisely, 24% of patients experienced an ETT occlusion after a median of 12 days. The HME group was younger (58.5 vs 64 years), predominantly male (75% vs 59.4%), and experienced more total ventilator days than the HH group (24 vs 12). Those using the studied HME devices had significantly higher odds of ETT occlusion (OR 4.4, 95% CI 1.8-10.6, P = .0011). Three patients (6.1%) experienced cardiac arrest as a consequence of their occlusion. There were no deaths directly attributed to ETT occlusion. Conclusions: The studied HME devices were significantly associated with higher odds of ETT occlusion in COVID-19 patients requiring invasive mechanical ventilation. These events are not without significant clinical consequences. Prolonged use of under-performing HME devices remains suspect in the occurrence of ETT occlusions.

BCR signaling is required for posttransplant lymphoproliferative disease in immunodeficient mice receiving human B cells.

Posttransplant lymphoproliferative disease (PTLD) is a major therapeutic challenge that has been difficult to study using human cells because of a lack of suitable models for mechanistic characterization. Here, we show that ex vivo-differentiated B cells isolated from a subset of healthy donors can elicit pathologies similar to PTLD when transferred into immunodeficient mice. The primary driver of PTLD-like pathologies were IgM-producing plasmablasts with Epstein-Barr virus (EBV) genomes that expressed genes commonly associated with EBV latency. We show that a small subset of EBV+ peripheral blood-derived B cells expressing self-reactive, nonmutated B cell receptors (BCRs) expand rapidly in culture in the absence of BCR stimulation. Furthermore, we found that in vitro and in vivo expansion of EBV+ plasmablasts required BCR signaling. Last, treatment of immunodeficient mice with the BCR pathway inhibitor, ibrutinib, delays onset of PTLD-like pathologies in vivo. These data have implications for the diagnosis and care of transplant recipients who are at risk of developing PTLD.

The dynamics of colicin E9 release from Escherichia coli in native conditions.

Colicin (Col) plasmid contains colicin encoding genes arranged in an operon controlled by an SOS inducible promoter. Therefore, any external stresses to the host cell can induce the expression of the downstream genes in the Col operon, including a lysis gene. The lysis protein is involved in the extracellular release of colicin through lysis of the producer cells, which causes a decline in culture turbidity. However, it is not yet known that E. coli cells with the native pColE9-J plasmid hold the same level of cell death at the population level following a set of induced conditions. In this study, using a mitomycin C sensitivity assay along with a live dead staining method of detection, we showed that the native pColE9-J plasmid, which unusually carries an extended Col operon (ColE9) containing two lysis genes, did not confer a rapid decline in the culture turbidity following induction with mitomycin C. Interestingly a subset of the cells suffered perturbation of their outer membrane, which was not observed from single lysis mutant (∆celE or ∆celI) cells. This observed heterogeneity in the colicin E9 release leading to differential outer membrane perforation may bring a competitive advantage to these cells in a mixed population.

Informing the pandemic response: the role of the WHO's COVID-19 Weekly Epidemiological Update.

On 31 December 2019, the Municipal Health Commission of Wuhan, China, reported a cluster of atypical pneumonia cases. On 5 January 2020, the WHO publicly released a Disease Outbreak News (DON) report, providing information about the pneumonia cases, implemented response interventions, and WHO's risk assessment and advice on public health and social measures. Following 9 additional DON reports and 209 daily situation reports, on 17 August 2020, WHO published the first edition of the COVID-19 Weekly Epidemiological Update (WEU). On 1 September 2023, the 158th edition of the WEU was published on WHO's website, marking its final issue. Since then, the WEU has been replaced by comprehensive global epidemiological updates on COVID-19 released every 4 weeks. During the span of its publication, the webpage that hosts the WEU and the COVID-19 Operational Updates was accessed annually over 1.4 million times on average, with visits originating from more than 100 countries. This article provides an in-depth analysis of the WEU process, from data collection to publication, focusing on the scope, technical details, main features, underlying methods, impact and limitations. We also discuss WHO's experience in disseminating epidemiological information on the COVID-19 pandemic at the global level and provide recommendations for enhancing collaboration and information sharing to support future health emergency responses.

Betanin dye extracted from ayrampo (Opuntia soehrensii) seeds to develop dye-sensitized solar cells.

Pigments extracted from ayrampo seeds of the Peruvian-native prickly pear (Opuntia soehrensii) were used in dye-sensitized solar cells with promising efficiencies. The performance of the solar cells was then improved via the addition of citric acid to stabilise the photosensitive dye, and an efficiency of 1.41% was achieved with current output remaining stable after 7 days. Upon testing in low-light conditions, the solar conversion efficiency of devices increased to 4%. This paper not only highlights the potential of natural sensitizers in DSSCs but also shows that simple extraction and gentle handling methods can contribute to the device performance.

Bringing people together through shared purpose and identity: lessons learnt from NHS Providers CEO Sir Julian Hartley.

INTRODUCTION: The healthcare sector is facing increased demand with reduced resources, yet despite these challenges, leaders such as NHS Providers CEO Sir Julian Hartley have created cultures where the workforce can realise shared values, through a focus on staff engagement. This article describes Julian's journey, through the eyes of a doctor-in-training working in an organisation he has led, to understand what we can learn from his approach to leadership. NARRATIVE: As a manager, Julian saw how many different people it takes to make the NHS work, and decided the role of an NHS leader was to bring people together, through a strong sense of shared purpose and identity. As CEO of Trusts in Blackpool and Leeds, he put this focus on staff engagement into practice to great success. Julian then introduced lean methods that flourished in the culture he had created, and when external factors such as COVID-19 began to erode that culture, returned to refresh that underpinning shared purpose. REFLECTION: Julian has developed a toolkit of behaviours and approaches, refined through experience and reflection, to help him elucidate and bring to life both the values and goals of the workforce. Because he shares these values, he has been able to lead with authenticity, creating engaged workforces, empowered to drive continuous improvement. We can reflect on Julian's approach as leaders ourselves: how can we align the values and visions of our staff, and ensure they are empowered to realise both?

Have outcomes of trauma in centenarians changed in the last 15 years?

BACKGROUND: Centenarians are an often forgotten and under-reported group. Trauma in this population is a substantial cause of morbidity and mortality. 15 years ago, a small observational study examined the outcomes of trauma in centenarians in a single trauma unit, concluding that age alone should not be a determinant of treatment. Following implementation of national standards of care for trauma patients in older adults, this study re-examined outcomes in centenarians admitted secondary to trauma to assess if outcomes have changed. MATERIALS AND METHODS: We performed a retrospective cohort study examining patients aged over 100 years who had been admitted with trauma to an acute district general hospital and trauma unit. Patients were admitted from January 2020 to January 2022. Outcomes investigated included duration of hospital stay, complications, and mortality at three timepoints (inpatient, 30 days, 12 months). We compared this cohort to the cohort 15 years ago to assess for changes in outcomes. RESULTS: 29 patients met our eligibility criteria in this cohort. Common presenting injuries included hip fracture (13), pelvic ring fractures (8) and head injuries (8). There was significantly higher inpatient mortality within our cohort between patients who underwent operative versus non-operative treatment, but no significant difference in duration of hospital stay. There was no significant change in duration of hospital stay, inpatient mortality, or mortality at 30 days and 12 months between this cohort and 15 years ago. CONCLUSIONS: Outcomes of centenarians admitted secondary to trauma have been maintained but not improved in the last 15 years in our centre. Following this we must consider if more must be done to improve outcomes in this underreported but growing patient demographic.

INvestigational Study Into Transplantation of the Uterus (INSITU): a cross-sectional survey among women with uterine factor infertility in the UK assessing background, motivations and suitability.

IMPORTANCE: The study summarises the selection prescreen criteria currently used in the UK for a uterus transplant and highlights the number of women who are suitable to proceed. OBJECTIVES: To assess the demographics, motivations, reasons and suitability among women with absolute uterine factor infertility (AUFI) to undergo uterine transplantation (UTx). DESIGN: A cross-sectional survey. SETTING: An electronic questionnaire was sent via email to women with AUFI who had previously been referred to the UTx research team or approached the Womb Transplant UK Charity. The questions assessed suitability to undergo UTx based on demographic information, perceptions to adoption and surrogacy and reasons why UTx was preferable. Responses were assessed against the study selection criteria. PARTICIPANTS: Women with AUFI. RESULTS: 210 women completed the questionnaire. The most common aetiology of AUFI in our cohort was Mayer-Rokitansky-Küster-Hauser (68%; n=143) whereas 29% (n=62) had previously undergone hysterectomy. 63% (n=132) of the cohort had previously considered adoption, 5% (n=11) had attempted it and 2 (1%) had successfully adopted. The most common reason cited to undergo UTx over adoption was to experience gestation (n=63; 53%), while 37% (n=44) wanted a biologically related child. 76% (n=160) of participants had previously considered surrogacy, 22 (10%) had attempted it and 2 (1%) had successfully become mothers using a surrogate. The most common reason to undergo UTx over surrogacy was to experience gestation (n=77; 54%). 15% (n=21) were concerned about the legal implications, 14% (n=20) identified the financial cost as a barrier and 8% (n=12) could not consider it due to religious reasons. On adhering to the selection criteria, 65 (31%) women were suitable to proceed with the trial. CONCLUSION: The study demonstrates that implementing commonly used selection criteria for a UTx led to an attrition rate of more than two-thirds of women who requested to initially undergo the process. As more studies present outcomes following UTx, critical assessment of the selection criteria currently used is warranted to ensure potential recipients are not being unnecessarily excluded. TRIAL REGISTRATION NUMBER: NCT02388802.

Tracking online searches for gambling activities and operators in the United Kingdom during the COVID-19 pandemic: A Google Trends™ analysis.

Background: Whilst some research has explored the impact of COVID-19 on gambling behaviour, little is yet known about online search behaviours for gambling during this period. The current study explored gambling-related online searches before, during and after the outbreak of the COVID-19 pandemic in the UK. We also assessed whether search trends were related to Gambling Commission behavioural data over the same period. Methods: Google Trends™ search data, covering thirty months from January 2020 to June 2022, for five gambling activities and five gambling operators were downloaded. Graphical displays of the weekly relative search values over this period were then produced to visualise trends in search terms, with key dates in COVID-19 policy and sporting events highlighted. Cross-correlations between seasonally adjusted monthly search data and behavioural indices were conducted. Results: Sharp increases in internet searches for poker, slots, and bingo were evident during the first lockdown in the UK, with operator searches sharply decreasing over this period. No changes in gambling activity searches were highlighted during subsequent lockdowns, although small increases in operator-based searches were detected. Strong positive correlations were found between search data and industry data for sports betting and poker but not for slots. Conclusions: Google Trends™ data may act as an indicator of population-level gambling behaviour. Substitution of preferred gambling activities for others may have occurred during the first lockdown when opportunities for sports betting were limited. Further research is needed to assess the effectiveness of internet search data in predicting gambling-related harm.

The Clinical Application of Platelet-Rich Plasma in the Female Reproductive System: A Narrative Review.

Platelet-rich plasma is an autologous plasma containing platelets prepared from fresh whole blood drawn from a peripheral vein. Through processing, it can be prepared to contain supraphysiologic levels of platelets at three to five times greater than the level of normal plasma. PRP has been explored both in vivo and ex vivo in the human endometrium model in its ability to harness the intrinsic regenerative capacity of the endometrium. Intrauterine autologous PRP infusions have been shown to increase endometrial thickness and reduce the rate of intrauterine adhesions. In the setting of recurrent implantation failure, intrauterine infusion of PRP has been shown to increase clinical pregnancy rate. PRP also appears to hold a potential role in select patients with premature ovarian insufficiency, poor ovarian responders and in improving outcomes following frozen-thawed transplantation of autologous ovarian tissue. Further studies are required to explore the potential role of PRP in reproductive medicine further, to help standardise PRP protocols and evaluate which routes of administration are most effective.

Adsorption-Controlled Growth and Magnetism in Epitaxial SrRuO3 Films.

Controlling defect densities in SrRuO3 films is the cornerstone for probing the intricate relationship among its structural, electrical, and magnetic properties. We combine film growth, electrical transport, and magnetometry to demonstrate the adsorption-controlled growth of phase-pure, epitaxial, and stoichiometric SrRuO3 films on SrTiO3 (001) substrates using solid source metal-organic molecular beam epitaxy. Across the growth window, we show that the anomalous Hall curves arise from two distinct magnetic domains. Domains with similar anomalous Hall polarities generate the stepped feature observed within the growth window, and those with opposite polarities produce the hump-like feature present exclusively in the highly Ru-poor film. We achieve a residual resistivity ratio (RRR = ρ300K/ρ2K) of 87 in a 50 nm-thick, coherently strained, and stoichiometric SrRuO3 film, the highest reported value to date on SrTiO3 (001) substrates. We hypothesize further improvements in the RRR through strain engineering to control the tetragonal-to-orthorhombic phase transformation and the domain structure of SrRuO3 films.

Human plasma cells engineered to secrete bispecifics drive effective in vivo leukemia killing.

Bispecific antibodies are an important tool for the management and treatment of acute leukemias. Advances in genome-engineering have enabled the generation of human plasma cells that secrete therapeutic proteins and are capable of long-term in vivo engraftment in humanized mouse models. As a next step towards clinical translation of engineered plasma cells (ePCs) towards cancer therapy, here we describe approaches for the expression and secretion of bispecific antibodies by human plasma cells. We show that human ePCs expressing either fragment crystallizable domain deficient anti-CD19 × anti-CD3 (blinatumomab) or anti-CD33 × anti-CD3 bispecific antibodies mediate T cell activation and direct T cell killing of specific primary human cell subsets and B-acute lymphoblastic leukemia or acute myeloid leukemia cell lines in vitro. We demonstrate that knockout of the self-expressed antigen, CD19, boosts anti-CD19 bispecific secretion by ePCs and prevents self-targeting. Further, anti-CD19 bispecific-ePCs elicited tumor eradication in vivo following local delivery in flank-implanted Raji lymphoma cells. Finally, immunodeficient mice engrafted with anti-CD19 bispecific-ePCs and autologous T cells potently prevented in vivo growth of CD19+ acute lymphoblastic leukemia in patient-derived xenografts. Collectively, these findings support further development of ePCs for use as a durable, local delivery system for the treatment of acute leukemias, and potentially other cancers.

Tackling antimicrobial resistance: developing and implementing antimicrobial stewardship interventions in four African commonwealth countries through a health partnership model.

In recent years, health partnerships have shared infection prevention and control innovations between United Kingdom hospitals and Low-Middle-Income Countries. However, none had focused on antimicrobial stewardship (AMS), a core component of tackling antimicrobial resistance (AMR). This paper documents an effective approach to developing a program to increase AMS capacity in four African countries: Ghana, Tanzania, Uganda, and Zambia as part of the Commonwealth Partnerships for Antimicrobial Stewardship (CwPAMS) program. A systematic approach was applied to assess gaps in AMS interventions and inform the development of the CwPAMS program through deskbased assessments, including National Action Plans on AMR, online focus group meetings, and expert advisory group reviews. Twelve partnerships were selected for the CwPAMS program. AMS support tools were developed based on recommendations from the scoping, including an AMS checklist tool, a healthcare worker knowledge and attitudes questionnaire, and an antimicrobial prescribing app to support clinical decision-making. Training workshops on AMS were developed and delivered to volunteers in Africa and the UK using a train-the-trainer model. The tools and workshops facilitated capacity building for AMS through the generation and strengthening of knowledge, skills, commitment, structures, systems, and leadership among stakeholders in the UK and Africa. The overall average rating assigned to the program following independent evaluation using the Organisation for Economic Cooperation and Development Assistance Committee Evaluation Criteria was very good. The evaluation also highlighted that the majority of the HPs (75%) focused on AMS and/or improved prescribing practice; all HPs have developed and implemented AMS strategies, guidelines, and tools within their hospitals; and NHS staff were able to translate the knowledge and skills they had received early on in the program into clinical practice in response to COVID-19 challenges.

Retropharyngeal Hematoma Causing Airway Compromise After Tissue Plasminogen Activator Administration: A Case Report.

INTRODUCTION: Tissue plasminogen activator (tPA), commonly used for treatment of acute ischemic stroke, is associated with life-threatening bleeding intracranially as well as surrounding the airway. CASE REPORT: A 78-year-old year old male who presented with stroke symptoms and after tPA administration developed a retropharyngeal hematoma requiring intubation and surgical intervention. CONCLUSION: Numerous threats to the patient's airway can develop after tPA administration. While angioedema is the most common cause, it is important to be prepared for other causes related to hemorrhage.

Association between troponin level and medium-term mortality in 20 000 hospital patients.

INTRODUCTION: Cardiac troponin (cTn) concentrations above the manufacturer recommended upper limit of normal (ULN) are frequently seen in hospital patients without a clinical presentation consistent with type 1 myocardial infarction, and the significance of this is uncertain. The aim of this study was to assess the relationship between medium-term mortality and cTn concentration in a large consecutive hospital population, regardless of whether there was a clinical indication for performing the test. METHOD: This prospective observational study included 20 000 consecutive in-hospital and outpatient patients who had a blood test for any reason at a large teaching hospital, and in whom a hs-cTnI assay was measured, regardless of the original clinical indication. Mortality was obtained via NHS Digital. RESULTS: A total of 20 000 patients were included in the analysis and 18 282 of these (91.4%) did not have a clinical indication for cardiac troponin I (cTnI) testing. Overall, 2825 (14.1%) patients died at a median of 809 days. The mortality was significantly higher if the cTnI concentration was above the ULN (45.3% vs 12.3% p<0.001 log rank). Multivariable Cox analysis demonstrated that the log10 cTnI concentration was independently associated with mortality (HR 1.76 (95% CI 1.65 to 1.88)). Landmark analysis, excluding deaths within 30 days, showed the relationship between cTnI concentration and mortality persisted. CONCLUSION: In a large, unselected hospital population, in 91.4% of whom there was no clinical indication for testing, cTnI concentration was independently associated with medium-term cardiovascular and non-cardiovascular mortality in the statistical model tested.
