Protocol for a phase I single-centre dose escalation trial of autologous thymus derived regulatory T cells in paediatric heart transplant recipients to prevent cardiac allograft vasculopathy (ATT-Heart)

Por: Aiyengar · A. · Fanelli · G. · Romano · M. · Patel · P. · Issa · F. · Panesar · D. · Muthialu · N. · Douiri · A. · Lombardi · G. · Burch · M.
Introduction

Cardiac allograft vasculopathy (CAV) is a critical predictor of the long-term success of heart transplantation and once it is established, progression to graft dysfunction and loss is inevitable, despite adherence to immunosuppression and medications that ameliorate cardiac risk factors. Regulatory T cells (Tregs) are key for maintaining immune balance in the periphery. Studies investigating adoptive transfer of ex vivo expanded Tregs isolated from blood have been shown to be feasible and safe with good evidence for Tregs reducing CAV lesions in animal models of transplantation. Here, we describe the protocol for the ATT-Heart Study which is a phase I clinical trial investigating autologous thymus-derived Treg cell therapy in nine paediatric heart transplant recipients.

Methods and analysis

Patients will be recruited from the heart transplant waiting list at Great Ormond Street Hospital. Individualised autologous thymus-derived and expanded Tregs (TR006) will be injected into patients 3–6 months after transplant and follow-up will be conducted as per the post-transplant standard of care protocol with no wean of standard of care immunosuppression. Primary endpoint includes occurrence of Dose-limiting Toxicities in patients receiving TR006. Further data from blood tests, endomyocardial biopsy tissue, coronary imaging and clinical follow-up will be collected.

Ethics and dissemination

This article is based on the ATT-Heart study Protocol (V.1.1; dated 19 December 2024). The ATT-Heart trial has received a favourable ethical opinion from the Health Research Authority and South-Central Oxford A Research Ethics Committee (IRAS Number: 1008875/REC reference: 24/SC/0333). Clinical trials authorisation approval from UK Medicines and Healthcare products Regulatory Agency has also been received. The clinical trial will be conducted in accordance with the principles of Good Clinical Practice and following the guidelines set as part of the Research Governance Framework for Health and Social Care and all applicable necessary local policies. It is intended that the findings of the clinical trial will be presented at national/international conferences and using social media and through patient groups for dissemination among their members. The results will also be published in international peer-reviewed journals.

You Can't Be With Your Patients All the Time—Patient and Staff Views of a Wearable Vital Signs Monitoring System

ABSTRACT

Aim

To explore staff and patient perception of the newly co-developed wearable monitoring system (WMS), including acceptability of use in clinical practice.

Design

Pragmatic qualitative descriptive study.

Methods

Semi-structured interviews were conducted with 12 patient participants and eight staff members between June 2023 and August 2024, and were analysed thematically.

Results

Three themes were identified, building on previous qualitative work around the use of WMS on hospital wards. The first theme—centralised continuous monitoring enhances care—explores how WMS provides staff with a means to provide safe, efficient care with the ability to see the vital signs away from the patient. Patients reported feeling safer, knowing they were being monitored when staff were not at the bedside. The second theme—human connection at the bedside—considers how both patients and staff emphasised that the system should not replace nurse/patient interactions and face-to-face care, even though it provided patients with a stronger sense of independence. The final theme—system usability and integration into care—focuses on use of the system in clinical practice and implications for the future.

Conclusion

Wearable monitoring systems have the potential to support nurses to provide safer, more efficient care, whilst providing reassurance to patients. However, centralised monitoring should not replace face-to-face clinical contact, and careful consideration should be given to who would benefit most from the technology.

Impact

This study extends existing knowledge of the impact of WMS from being a tool to enhance patient safety to an intervention to improve nurse efficiency and patient experience, within the context of a high-demand surgical ward.

Patient and Public Contribution

Patients and members of the public were involved in study design and data collection. Their contributions included participating in advisory groups, ensuring the research addressed patient-relevant priorities.

Por: Lancia · L. · Dante · A. · Caponnetto · V. · Petrucci · C. · Masotta · V. · Mammarella · L. · Romano · S.
Objective

Heart failure (HF) is a major public health issue due to its high morbidity, mortality and healthcare burden. This study aimed to provide estimates of HF incidence, survival rates, outcome changes and their predictive factors in a central Italian population over the decade 2014–2023.

Design

Population-based retrospective cohort study.

Setting

Hospital discharge records from all hospitals in L'Aquila Province of Italy were analysed.

Participants

All residents who experienced a HF index hospitalisation between 2014 and 2023 were included. HF index hospitalisation was defined as the first hospitalisation for HF in patients with no prior hospitalisation from the same diagnosis for at least 4 years.

Primary outcome measures

The primary outcomes were age-standardised and sex-standardised incidence rates of HF index hospitalisations and all-cause mortality following index hospitalisation. Incidence rate ratios (IRRs), survival and their associated factors were analysed with negative binomial regression models, Kaplan-Meier analysis and Cox proportional hazards models, respectively.

Results

A total of 6965 incident cases from 17 588 HF hospitalisations in the decade under study were analysed. The overall standardised incidence rate was 1.73 per 1000 person-years, with significant differences by age and sex. Incidence rates decreased by 17% from 2014–2018 to 2019–2023 (IRR: 0.834; 95% CI 0.743 to 0.936). Cumulative 1-year and 5-year survival were 70.05% and 36.38%, respectively, with a progressively higher mortality risk in older people. Compared with the 2014–2018 cohort, the 2019–2022 cohort showed improved survival at 30 and 90 days and at 1 year overall and by age groups, with

Conclusions

HF incidence declined, particularly in older populations, and remained higher in men, while survival rates improved. Despite these trends, HF continues to represent a substantial clinical and public health burden.

The effects of increasing dosages of narasin on ruminal fermentation patterns, bacterial community composition, and nutrient digestibility in beef cattle receiving feedlot diets

by Ana Laura Januário Lelis, Leandro Aparecido Ferreira da Silva, Daniel Moretto Casali, Tiago Leiva, Murilo Chuba Rodrigues, José Paulo Roman Barroso, Pedro Veloso Facury Lasmar, Camila Lisboa Tomaz, Anabelle Jorge Barbosa, Camila Cesario Fernandes Sartini, Johnny Maciel de Souza, Danilo Domingues Millen

This study evaluated the effects of increasing narasin doses on ruminal fermentation, nutrient digestibility, ruminal pH stability, papillae histology, and microbial composition in Angus cattle fed feedlot diets. Three rumen-cannulated Angus steers (average body weight: 680 kg) were assigned to a 3 × 3 Latin square design and received diets containing 13, 20, or 27-ppm of narasin. Each experimental period consisted of 14 days of adaptation followed by seven days of sampling. Ruminal degradability was assessed on days 15–17, apparent digestibility on days 15–19, continuous ruminal pH on days 19–20, and samples for short-chain fatty acids (SCFA), microbiota, and ruminal histology were collected on days 20 and 21. Ruminal degradability was not affected by narasin dose. Digestibility of acid detergent fiber (ADF) was significantly influenced, with the greatest values observed at 27-ppm (P = 0.01). Increasing narasin doses improved ruminal pH stability, as indicated by a linear increase in minimum pH (P = 0.01) and a reduction in the duration of pH below 5.6 (P = 0.10). At 13 ppm, SCFA production, particularly acetate and propionate, increased (P P P = 0.02), and butyrate (P P P = 0.03). Narasin supplementation altered ruminal microbial composition, increasing the relative abundance of Lachnospiraceae and Isotricha while reducing lactic acid–producing bacteria. In terms of ruminal morphology, supplementation with 20-ppm of narasin increased the keratin layer thickness of ruminal papillae (P = 0.02), suggesting enhanced epithelial development. Overall, narasin supplementation modulated ruminal function and microbial ecology, with doses between 13 and 20-ppm providing the most favorable balance between fermentative efficiency and ruminal health in feedlot cattle.

Por: Lalchandani · N. · Romaniuk · H. · Cameron · A. · Orellana · L. · Ananthapavan · J. · Peeters · A. · Backman · B. · Adam · M. · Allender · S. · Nguyen · P. · Sacks · G. · Brimblecombe · J. K. · McMahon · E. · Blake · M.
Introduction

Food retail outlets in sports and recreation facilities often fail to support healthy eating, despite aligning with healthy lifestyles and goals of local governments (LGs) that often own or manage them. LGs face barriers to implementing facility changes including inadequate staffing, training and incentives. The Promoting CHANGE initiative was co-designed to support LGs in improving and sustaining healthier food and drink offerings in these settings.

Methods and analysis

A 3-year, type 2 effectiveness-implementation hybrid cluster randomised controlled trial will evaluate the Promoting CHANGE capacity-building and support package in three Intervention and four Control LGs in Victoria, Australia (August 2023–July 2026). The co-designed initiative includes human resource support, training, tools, technical assistance, community-of-practice groups, feedback based on food outlet audit and sales data and small grant incentives. Using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) evaluation framework, the trial’s co-primary outcomes are the percentage of least healthiest food and drinks (1) displayed (implementation) and (2) sold weekly (effectiveness). Key secondary outcomes are effectiveness (sales and revenue); facility-level adoption, implementation, maintenance of healthy changes; cost-effectiveness (within-trial modelled economic evaluation). Findings will provide evidence of the initiative’s effectiveness and scalability, informing recommendations for advancing healthier food environments in over 6000 community-based food outlets across 500 Australian LGs, with implications globally.

Ethics and dissemination

This study has received approval from the Deakin University Human Research Ethics Committee (reference number HEAG-H 92_2023). The results will be published in scientific peer-reviewed journals along with plain language summaries for participants.

Neoplastic Foot Ulcers: A Multicentre Retrospective Study

ABSTRACT

Neoplastic foot ulcers are particularly challenging for dermatologists and specialists in hard-to-heal wounds because their location and comorbidities can delay accurate diagnosis. We performed a multicentre, retrospective study analysing clinical and histological data, focusing on neoplastic foot ulcers collected over the past 5 years. We evaluated patients' demographic characteristics, clinical features, histological diagnosis, tumour onset and ulcer site. Statistical analyses were conducted using SPSS software, v.30. In total, 106 patients affected by foot skin ulcers were enrolled in the present protocol (52 women, 54 men). The mean age was 70.15 years. In most cases, the neoplastic ulcer was due to primary tumour ulceration. The dorsum of the foot was the most common site of neoplastic ulcers (66%). From a clinical perspective, most lesions were classified as ulcerated nodules (n = 58), ulcerated plaques (n = 8) or hypergranulating ulcers (n = 25), all with thickened, atypical edges. Histological diagnoses included melanoma (n = 45), non-melanoma skin cancers (n = 34), benign tumours (n = 18) and rarer malignancies (n = 9). A statistically significant correlation was found between histotype and clinical lesion type, and between age and histotype. The study provided preliminary data on the clinical and histological characteristics of neoplastic foot ulcers, warranting further exploration in a prospective, multicentre study.

Screening for hypertension in the inpatient environment (SHINE): a prospective diagnostic accuracy study among adult hospital patients

Por: Armitage · L. C. · Roman · C. · Lawson · B. K. · Mahdi · A. · Biggs · C. · Young · L. · Edmundson · H. · Fanshawe · T. · Tarassenko · L. · Farmer · A. · Watkinson · P. J.
Background

Hypertension is the leading risk factor for death globally. Undiagnosed hypertension is common, but the incidence in hospitalised patients is unclear. There are calls for universal facility-based screening for hypertension among all attending patients. The hospital inpatient setting, where blood pressure (BP) is measured routinely and repeatedly, presents an ideal opportunity. However, international hypertension guidelines do not include inpatient BP thresholds for diagnostic or treatment purposes. We investigated the performance of current UK community BP thresholds for diagnosing hypertension in the hospital setting.

Objectives

Investigate the diagnostic performance of the current UK ambulatory BP diagnostic thresholds for systolic and diastolic hypertension in the hospital setting against the reference test of community-based ambulatory BP monitoring (ABPM).

Design

A prospective diagnostic accuracy study.

Setting

Hospital inpatients admitted to three UK centres were approached. Follow-up ABPM was delivered in the community.

Participants

Eligible patients were aged between 18 and 80 years, with no prior diagnosis of, or prescription for hypertension, and whose mean cumulative daytime BP was 120 mm Hg to 179 mm Hg systolic and ≤109 mm Hg diastolic from the 24th hour of their hospital admission.

Interventions

Participants received 24-hour ABPM 4–26 weeks post-discharge, as the reference test for hypertension, with UK diagnostic thresholds of an average daytime BP of ≥135 mm Hg systolic and ≥85 mm Hg diastolic applied. Participants found to be severely hypertensive at the ABPM fitting appointment were also considered reference-test positive but did not proceed with ABPM.

Primary and secondary outcome measures

The diagnostic performance of a mean daytime in-hospital BP of ≥135 mm Hg systolic or ≥85 mm Hg diastolic (index test) for the prediction of hypertension diagnosed on ABPM (reference test) was assessed using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) as primary outcome measures. Additionally, we explored the accuracy of a range of alternative in-hospital systolic and diastolic BP thresholds against the same reference test.

Results

351 participants were enrolled and 206 completed the study protocol. The average age of the 206 participants was 53 years, 55% were male, and 91 (44%) had daytime community hypertension on ABPM reference testing. Of 107 participants with raised in-hospital daytime BP, 59 (55%) had daytime community hypertension. When assessing the performance of the index test for detecting daytime community hypertension, sensitivity was 65% (59/91, 54% to 75%) and specificity was 58% (67/115, 49% to 67%). The PPV was 55% (59/107, 45% to 65%) and NPV was 68% (67/99, 58% to 77%), respectively. A further 45/206 participants (23%) had night-time community hypertension when assessed using European diagnostic thresholds for nocturnal hypertension (120 mm Hg systolic or 70 mm Hg diastolic), while 25/107 of those with raised in-hospital daytime BP (23%) had night-time community hypertension. When assessing the performance of the index test for detecting either day or night-time community hypertension, sensitivity was 62% (84/135, 53% to 70%) and specificity was 68% (48/71, 55% to 78%). The PPV was 79% (84/107, 70% to 86%) and NPV was 48% (48/99, 38% to 59%).

Conclusions

Undiagnosed hypertension is common in hospitalised patients, particularly those with raised in-hospital BP. While in-hospital BP alone is an imperfect predictor and should not be used as a stand-alone diagnostic test, this could serve as a trigger for further assessment of BP in the community after discharge.

Trial registration number

The study protocol was registered with the ISCTRN Registry (ISRCTN80586284).

Reliability and Validity of the Italian Translation of the Updated Version of the Pressure Ulcer Knowledge Assessment Tool (PUKAT 2.0)

ABSTRACT

The study aimed to translate the PUKAT 2.0 tool from English to Italian. This was an adaptation and validation study; the validity of the Italian version was determined through content validity, item validity and construct validity. The reliability of the instrument was assessed by conducting a test–retest analysis on a sample of 62 nurses. The I-CVI indices were above the threshold of 0.78 for 91% of the questions, and according to the S-CVI index, 96% of the evaluators agreed that the questionnaire was highly relevant. The overall values for item difficulty were good, with two items being too difficult and none being too easy. The item discriminant index was overall good and reasonable, low for four items. The overall ICC was poor to moderate with a value of 0.48 (95% CI 0.26–0.65). The instrument has proven to be a good starting point although not yet completely reliable, as it clearly requires more basic preparation on the part of the staff, further modifications regarding the reliability and clarity of the questions and more training of the nursing staff if it is to be used in the Italian context.

Clinical Guidelines for Virtual Health Assessment and Care: A Scoping Review

ABSTRACT

Aim

To locate and synthesise clinical guidelines for nurses and other health professionals undertaking routine virtual health (telehealth) assessment, triage and follow-up care. To locate practice guidelines where clinician and client are not in the same physical location and health assessments are undertaken ‘virtually’.

Design

This review used JBI methodology for scoping reviews and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review extension (PRISMA-ScR).

Data Sources

Search considered primary research, practice guidelines, case reports, expert opinions, professional organisation web-based resources and grey literature. Medline (Ovid), Cumulative Index to Nursing & Allied Health (CINAHL) and Scopus databases were searched in relation to all health professions. Grey literature search included guideline databases, literature databases, customised Google search engines, targeted websites and consultation with content experts. Citation searching was included.

Results

Search identified 2359 peer-reviewed articles and 31 sources of grey literature (1997–2024). After screening, 22 peer-reviewed and 9 grey literature sources met the eligibility criteria for inclusion. Studies were spread across diverse practice settings. Chronological sequencing provided visibility to innovations in telehealth practice over time from telephone-based practice to the introduction of video conferencing and the use of wearable devices for the transmission of remotely recorded clinical information.

Conclusions

Standardised guidelines to safe practice for virtual health assessment are not well documented. The paucity of clinically orientated guidelines may be due to complexity and the resourcing needed to maintain clinically current guidelines across the full breadth of clinical specialisations, practice settings and telehealth modalities. Further research and development are needed in this growing area of care.

Impact

The review highlights that clinically relevant guidelines are critical to safety and quality in virtual health contexts. Findings will inform future design and development of clinical practice guidelines for nurses engaged in virtual health assessment, triage and follow-up care.

Investigating organizational resilience in a medicine and health sciences university in United Arab Emirates

by Tamara Muir, Chandra Sharma Poudyal, Romana De Lima, Farah Otaki

Introduction

COVID-19 pandemic emerged in late 2019, leading to global disruption and forcing people to adapt to a new reality. The intensity of the pandemic affected many organisations’ preparedness, response, and recovery efforts, causing numerous businesses to struggle. Although no single theory fully explains why some businesses thrived during this time, the concept of organisational resilience stands out. Organisations with a resilient culture seemed better equipped to address risks, adapt effectively, and seize opportunities for innovation. Therefore, the purpose of the current study is to critically examine the response to COVID-19 of a medicine and health sciences university in Dubai, United Arab Emirates.

Methods

The study relied on a convergent mixed methods approach to research. A tailor-made questionnaire was used to collect quantitative data using two 5-point Likert-type scales: ‘Opinions about Organizational Response’ and ‘Conducive Organizational Response Behaviours’ (where 110 current employees who were tenured during COVID-19 were selected, using purposive, non-probability sampling, and in turn invited to participate). Semi-structured interviews were conducted to collect qualitative data [where seven respondents who had completed the questionnaire and agreed to participate in follow-up interviews were selected (i.e., convenience, nonprobability sampling) and in turn invited to participate]. The quantitative data were descriptively and inferentially analysed. Qualitative data was analysed using an inductive six-step thematic approach. The quantitative findings were mapped onto the output of qualitative analysis using the iterative joint display analysis process.

Results

A total of 70 employees completed the questionnaire (63.64%), and six out of seven invitees participated in the semi-structured interviews. The percentage of the total extent of agreement of ‘Opinions about Organizational Response’ score was 90.94%. As for the percentage of the total frequency of observation of ‘Conducive Organizational Response Behaviours’ score, it was 95.08%. The qualitative analysis generated a conceptual model, namely: ‘Enablers of Organizational Resilience’, with five interlinked themes namely: Preparedness and planning for uncertainty, Adaptation and agility, Team cohesion, Social responsibility, and Learning organisation. Four meta-inferences emerged from integrating the data findings: Response characteristics, Behaviour specificities, Consistency of opinions, and the Fundamental role of organizational culture.

Conclusion

The findings reveal that organizations, in the intersect between higher education and public health, should continue on innovatively investing in agile leadership, strategic partnerships, and a robust continuous learning and development culture to better navigate future disruptions.

Optimizing vitamin A supplementation: A comparative cost-effectiveness analysis of routine distribution strategies in northern Côte d’Ivoire

by Melissa M. Baker, Lyonel Nerolin Doffou Assalé, David Doledec, Romance Dissieka, Ahmenan Claude Liliane Konan, Agnes Helen Epse Assagou Mobio, Koffi Landry Kouadio, Oka René Kouamé, Ama Emilienne Yao, Hubert Zirimwabagabo

Background

While recent data on vitamin A deficiency (VAD) prevalence is lacking, the 2004 Côte d’Ivoire Nutrition and Mortality Survey reported that 26.7% of children aged 6–59 months were affected by VAD, and approximately 60% were at risk. Since 2016, the government has transitioned from mass campaigns to routine vitamin A supplementation (VAS) delivery integrated into health services. However, evidence on the cost-effectiveness of the routine distribution approaches is limited. This study evaluated the cost, coverage, and cost-effectiveness of three routine VAS delivery strategies across two health districts in northern Côte d’Ivoire.

Methods

A mixed-methods study evaluated three routine VAS delivery strategies – routine-fixed, advanced community-based, and catch-up – across two health districts, Ferkessédougou and Niakaramadougou, in northern Côte d’Ivoire. The quantitative cost data were collected via a structured tool covering six cost categories: planning, procurement, training, social mobilization, distribution, and supervision. VAS coverage was assessed through a post-event coverage survey (PECS) via a two-stage cluster sampling methodology. A cost-effectiveness analysis determined the cost per child supplemented, the cost per DALY averted, and a sensitivity analysis tested the robustness of the findings under different cost scenarios.

Results

The total program cost for July-December 2023 was 25.5 million FCFA, with personnel costs comprising over 70% of expenditures. In Ferkessédougou, the routine advanced community-based strategy was the most cost-effective, at 458 FCFA per child in rural areas (versus 596 FCFA for the routine-fixed facility-based approach in the same area). In Niakaramadougou, the December catch-up was more cost-effective in rural areas (606 FCFA per child) than the routine-fixed approach (714 FCFA). Across both districts combined, the routine-fixed strategy averaged roughly 651 FCFA per child supplemented, and the cost per DALY averted ranged from 30,093 FCFA (advanced strategy in Ferkessédougou) to 89,550 FCFA (catch-up Jul 2023 in Niakaramadougou) – all below Côte d’Ivoire’s cost-effectiveness threshold (0.5 x GDP per capita; approximately USD 1,265).

Conclusion

All three strategies were cost-effective, though the advanced community-based strategy achieved the best balance of reach and efficiency. Scaling advanced strategies within health system constraints may enhance sustainability and coverage in low-resource settings.

Robot-assisted versus standard laparoscopic approach of total hysterectomy for deep infiltrating endometriosis and adenomyosis (ENDORAS TRIAL): study protocol for a randomised controlled trial

Por: Renso · M. · Bendifallah · S. · Estrade · J.-P. · Merlot · B. · Roman · H. · Vidal · F. · Collinet · P.
Introduction

Endometriosis affects 5–10% of women during reproductive years, with a 20–30% incidence among those with infertility. Deep infiltrating endometriosis (DIE) affects 10–15% of women of childbearing age and 50% of infertile women. When hormonal therapy and conservative surgery prove ineffective, total hysterectomy with or without bilateral salpingo-oophorectomy may be the ultimate therapeutic option. Laparoscopic surgery is the gold standard for treating endometriosis, offering effective disease eradication, safety, reduced pain, shorter hospital stay and faster recovery compared with laparotomy. However, patients undergoing total laparoscopic hysterectomy with DIE have higher risks of complications and organ damage, particularly urinary tract damage. Robot-assisted laparoscopic hysterectomy has emerged as a promising alternative, with a significantly lower conversion rate than total laparoscopic hysterectomy in patients with endometriosis. This study evaluates the safety and efficacy of robot-assisted total laparoscopic hysterectomy (RATLH) versus total laparoscopic hysterectomy (TLH) in the management of DIE. We hypothesise that robot-assisted laparoscopic hysterectomy will result in fewer complications and better outcomes compared with total laparoscopic hysterectomy in DIE patients.

Methods and analysis

The ENDORAS trial is a prospective, multicentre, open-label, randomised controlled trial conducted in French reference hospitals specialising in endometriosis surgery. A total of 224 adult women patients will be enrolled in this study if they have DIE with adenomyosis, and without digestive tract involvement as confirmed by MRI. Participants will be randomised to undergo either RATLH or TLH. The primary outcome will be the intraoperative and postoperative complication rates, classified according to the Clavien-Dindo classification (grade 2 or above) at the 3-month postoperative follow-up. Among the secondary outcomes, we will evaluate the quality of life using various questionnaires, including the Endometriosis Health Profile-30, the Short Form-306 and the Female Sexual Function Index.

Ethics and dissemination

The ENDORAS trial will be conducted in accordance with the International Council on Harmonization Good Clinical Practice guidelines. All trial documents and procedures have been reviewed and approved by the Ethics Committee Ile de France II (approval ID number: 24.01408.000300). Informed consent will be obtained during the preoperative check-up by the operating gynaecologist. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media and the internet.

Objectives

To assess the comparative effectiveness of educational interventions in neurological disease for healthcare workers and students.

Design

Systematic review.

Data sources

Medline, Embase and Cochrane through to 1 June 2025.

Eligibility criteria

Studies evaluating neurological disease educational interventions with a comparator group (observational cohort/randomised controlled trial (RCT)) were included.

Data extraction and synthesis

A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic review was conducted (PROSPERO: CRD42023461838). Knowledge acquisition and educational methodologies were collected from each study. Study outcomes were classified using the Kirkpatrick and Kirkpatrick four-level model (learner reaction, knowledge acquisition, behavioural change, clinical outcome).1 Risk of bias was assessed using the Newcastle-Ottawa scale for non-randomised studies and the Cochrane Risk of Bias tool for RCTs.2 3

Results

A total of 67 studies involving 4728 participants were included. Of these, 36 were RCTs, and 31 were observational studies. Virtual interventions were the most common (67.2%, n=45 studies), primarily targeting either medical students (46.3%, n=31 studies) or specialists (40.3%, n=27 studies). Overall, 70.1% (n=47) of studies demonstrated outcomes in favour of the intervention. However, few studies used K&K level 3/4 outcomes, with two studies evaluating behaviour change (level 3) and three assessing clinical outcomes (level 4 combined with other levels). No study exclusively assessed level 4 outcomes. Meta-analysis of 22 RCTs with calculable standardised mean differences (SMDs) (n=1748) showed a significant benefit of interventions (SMD 0.75, 95% CI 0.22 to 1.27, p=0.0056).

Conclusions

This review highlights a growing body of research particularly focusing on virtual techniques, specialist audiences and treatment-oriented content. Few studies assessed changes in practice or patient care. Non-specialists remain underrepresented. Future studies should prioritise assessing the clinical impact of educational interventions within non-specialist audiences.

Burden of sickle cell anemia in Africa: A systematic review and meta-analysis

by Bwambale Jonani, Emmanuel Charles Kasule, Bwire Roman Herman, Joel Fredrick Arturo, Mwesigwa Calvin Mugambwa, Ssebulime Stephen, John Bosco Mundaka, Richard Kwizera, Gerald Mboowa, Felix Bongomin

Introduction

Sickle Cell Anemia (SCA) is a significant genetic disorder in Africa; however, comprehensive data on its prevalence and geographic distribution remain limited. We aimed to estimate the pooled prevalence of SCA (HbSS) in African populations and examine regional, demographic, and temporal variations from 1994–2024.

Methods

We systematically searched PubMed, Scopus, Google Scholar, and BASE databases for studies reporting SCA prevalence in African populations. Screening and quality assessments were performed using JBI tools. A random-effects meta-analysis with logit transformation was performed, with subgroup analyses by region, age, sex, and study design. Meta-regression explored heterogeneity sources, including geographic region, age category, diagnostic method, study design, and publication year.

Results

From 115 studies with 1,203,839 participants and 17,458 confirmed HbSS cases, the pooled prevalence was 1.43% (95% CI: 1.08%–1.88%), with substantial heterogeneity (I2 = 99.1%) and a prediction interval of 0.21%–8.91%. Central Africa showed the highest prevalence (1.99%), and Southern Africa showed the lowest (0.59%). Children exhibited a higher prevalence (1.65%) than adults (0.45%), while sex differences were non-significant (males 2.71%, females 1.74%; p = 0.694). The prevalence has remained stable over three decades despite a six-fold increase in research output, although wide prediction intervals indicated substantial between-study variability. Electrophoretic techniques predominated (86.4% of cases). Diagnostic method (χ² = 16.73, p = 0.033) and age category (χ² = 33.66, p 2 = 98.6%). Leave-one-out sensitivity analysis showed that no single study significantly impacted the pooled estimates.

Conclusion

SCA represents a substantial and geographically variable public health challenge across Africa. These findings highlight the need for region-specific interventions, expanded newborn screening programs, improved diagnostic accessibility with quality assurance for point-of-care technologies, and continued surveillance to address geographic gaps.

Reproduction of porcine ear necrosis (ear-tip necrosis) following intradermal inoculation of pigs with <i>Fusobacterium necrophorum</i>

by Matheus de O. Costa, Roman Nosach, Maite H. M. de Almeida

Porcine ear necrosis (PEN) (also referred to as ear-tip necrosis, ETN) is a syndrome of global presence and unclear aetiology. Initially reported in the 1950s, many different infectious and non-infectious causes have been suggested as the causative(s) agent(s), but none has been confirmed in controlled studies. Here, we investigated the aetiology of PEN using pure culture of bacteria associated with lesions in controlled animal trials. A commercial farm with no history of ear-tip necrosis was identified and used as the source for 5-week-old pigs. Two independent trials were initially executed with identical designs. Piglets (=12/trial) were intradermally inoculated with either pure cultures of Staphylococcus hyicus or Fusobacterium necrophorum (left ear, n = 10) or sterile media (right ear, n = 10). Two pigs in each trial were not inoculated, serving as sentinels. A third trial used F. necrophorum as the inoculum, 3 pigs as sentinels and 9 as inoculated. All animals were clinically monitored daily following challenge, and an ear score was used to follow disease progression. All ears inoculated with S. hyicus remained lesion free. Four out of ten and 7/9 pigs challenged with F. necrophorum developed lesions undistinguishable from PEN, including necrosis and loss of portions of the ear pinna (P F. necrophorum was isolated from 4/10 and 7/9 pigs that developed necrotic lesions. Histopathology after resolution of necrosis revealed granulomatous tissue. Evidence presented here suggests that F. necrophorum causes PEN-like lesions, as seen in commercial barns. It is therefore suggested as the etiological agent of this syndrome.

Introduction

Tuberculosis (TB) is a major global cause of morbidity and mortality. Emerging evidence in high-burden settings suggests significant long-term sequelae among people surviving TB; however, evidence from high-income, low-TB burden settings like Canada is lacking. In a person with TB infection, provision of TB preventive treatment (TPT) can prevent TB disease and its sequelae, but remains underused. We propose the Functional Outcomes, Lung health and Livelihood Outcomes among people With Tuberculosis study, a multicentre, prospective cohort study in Canada to help improve our understanding of the impacts of TPT and TB disease on individuals.

Methods and analysis

This is a prospective cohort study taking place in Montreal and Vancouver, Canada. We aim to recruit and retain at least 120 people with microbiologically confirmed TB disease, 340 people treated for TB infection and 120 without TB disease or infection who will be considered our unexposed group. All participants must be ≥6 years of age. Participants with TB disease or infection will be recruited within 2 weeks of treatment initiation. We will follow-up unexposed participants and participants with TB disease for 24 months, and participants with TB infection for 12 months. Throughout follow-up, participants will complete assessments measuring lung health and function, quality of life, disability, dyspnoea, psychological distress, as well as changes in employment and direct and indirect costs incurred because of treatment. Among participants with TB disease, our primary outcome is the difference in quality-adjusted life years between participants with TB disease and those unexposed at 24 months. For participants with TB infection, our primary outcome is the identification of non-patient characteristics (eg, patient cost, quality of life) associated with participant decision to discontinue treatment. Patient partners have contributed to the design of the study and will be involved with the study through to its dissemination.

Ethics and dissemination

This study has been approved by institutional ethics review boards at The Research Institute of the McGill University Health Centre (2025–10344) and The University of British Columbia (H24-02071). All participants will provide informed consent (and assent, if required) prior to participating in the study. We will disseminate study results to participants, national and international organisations, and through open-access peer-reviewed academic journals and conferences.

Tourniquets as a haemorrhage control measure in military and civilian care settings: An integrative review

Abstract

Aims and objectives

The aim of review was to describe and synthesise the evidence on the use of tourniquets to control haemorrhages, summarising both civilian and military use.

Background

Trauma-related haemorrhage constitutes one of the most preventable deaths among injured patients, particularly in multi-casualty incidents and disasters. In this context, safe instruments such as tourniquets are essential to help healthcare professionals to minimise loss of life and maximise patient recovery.

Design and methods

An integrative review was conducted in Medline, Nursing & Allied Health Premium, and Health & Medical Collection, using published data until March 2021 and following the PRISMA guidelines.

Results

A total of 25 articles were included. Evidence has been synthesised to understand the use of different types of tourniquets, environment of application, indication for their placement and potential complications associated with tourniquet placement.

Conclusions

Commercial tourniquets such as Combat Application Tourniquet or Emergency Tourniquet models are a valuable and safe instrument for haemorrhage control in both military and civilian out-of-hospital care settings. Nurses, as part of emergency teams, and other professionals should be aware that there is a possibility of adverse complications, but they are directly proportional to the time of tourniquet placement and generally temporary. In addition, national and international guidelines ensure the need for all civilian emergency services to be equipped with these devices, as well as for the training of healthcare professionals and first responders in their use.

Relevance to clinical practice

Despite the lack of complications in the use of tourniquets in these cases, their use has been a matter of debate for decades. In this sense, this review yields up-to-date guidelines in the use of tourniquets, their recommendations and their significance among professionals to manage complicated situations.

Introduction

Despite the known haemostatic action of emicizumab (Hemlibra) in haemophilia A patients, its role in the prevention and control of bleeding in high-demand haemostatic situations, such as major surgery, remains to be determined. Patients receiving regular emicizumab prophylaxis often require concomitant factor VIII (FVIII) therapy during major surgery to prevent uncontrolled bleeding and to promote postoperative healing. However, there are limited prospective surgical data relating to concomitant FVIII and emicizumab use. Simoctocog alfa (Nuwiq) is a B-domain deleted recombinant FVIII produced in a human cell line without chemical modification or protein fusion with proven efficacy as surgical prophylaxis in adult and paediatric patients. The Nuwiq for Perioperative management Of patients With haemophilia A on Emicizumab Regular prophylaxis (NuPOWER) study aims to examine perioperative efficacy and safety of simoctocog alfa in haemophilia A patients on emicizumab prophylaxis undergoing major surgery.

Methods and analysis

NuPOWER is a prospective, open-label, single-arm, multicentre study that will be conducted at approximately 15 centres worldwide. Up to 28 male patients ≥12 years with severe haemophilia A and no FVIII inhibitors will be recruited. All patients must be receiving regular emicizumab prophylaxis and scheduled to undergo a major surgical procedure during which concomitant simoctocog alfa will be administered. The primary endpoint is the overall haemostatic efficacy of simoctocog alfa, adjudicated by an independent data monitoring committee using a pre-defined algorithm, and will consider intraoperative and postoperative efficacy assessments by the surgeon and investigator, respectively. Secondary endpoints include intraoperative haemostatic efficacy, postoperative haemostatic efficacy, number of allogeneic blood products transfused, perioperative FVIII plasma levels (as measured by FVIII activity) and thrombin generation, and safety parameters. In the era of non-factor therapy, NuPOWER will generate valuable prospective data on concomitant use of simoctocog alfa and emicizumab prophylaxis in patients with severe haemophilia A undergoing major surgery.

Ethics and dissemination

Ethical approval has been received from institutional review boards/independent ethics committees, and the study will be conducted in compliance with the Declaration of Helsinki. This work will be disseminated by publication of peer-reviewed manuscripts and presentations at scientific meetings.
