This study investigated the efficacy and safety of a novel thermo-reversible antimicrobial wound gel (TRG, revyve Antimicrobial Wound Gel) designed to combat biofilm-related infections in wounds. The TRG was evaluated for its ability to disrupt biofilms, sustain antimicrobial activity and promote wound healing. The gel exhibited thermo-reversible properties, transitioning from a less viscous liquid ≤ 18°C to a highly viscous solid gel at wound temperature which would facilitate easy application and removal. Antimicrobial testing demonstrated that TRG effectively inactivated a broad range of wound-related pathogens, including Staphylococcus aureus and Pseudomonas aeruginosa, with a 99.99%–99.9999% reduction in bacterial counts within 30 min. The TRG also maintained its antimicrobial efficacy after multiple inoculations with high microbial load (107 CFU/mL) over 7 days. In vitro biofilm assays showed effectiveness against biofilm bacteria with a reduction of ≥ 99.99% bacterial counts with one application over the course of 7 days. Biocompatibility testing confirmed that TRG was safe, with no signs of tissue necrosis or signs of tissue damage and no impact on wound healing in a porcine wound model. TRG's ability to reduce both planktonic and biofilm-based bacteria without compromising wound healing makes it a promising candidate for treating both chronic and acute wounds.

Mitochondrial metabolism plays a critical role in determining lifespan across animal taxa. In our study, we used the Western honeybee (Apis mellifera) as a model, capitalizing on the stark lifespan difference between queens, which often live more than two years, and summer workers, which survive only about 30 days, despite sharing the same genetic background. We investigated mitochondrial function in head tissue, thoracic muscle, and abdominal fat tissue of queens and workers, comparing early (7 days) and late adult stages (28–30 days in workers; 2 years in queens). No significant differences in mitochondrial flux control ratio for the NADH- Succinate- and glycerophosphate (Gp) pathways were found in thoracic muscles across castes or age groups. In head and abdominal fat tissues, early-life queens showed reduced reliance on NADH-linked pathways for maximal respiratory flux compared to workers. The decrease in the NADH-pathway was compensated by an increase in the Gp-pathway contribution. Queens exhibited reduced phosphorylation-pathway control over OXPHOS compared to workers, both in head tissue during early life and in abdominal fat tissue later in life. These findings reveal caste- and tissue-specific patterns of mitochondrial regulation that may contribute to dramatic lifespan divergence observed in eusocial insects. They suggest that early-life metabolic flexibility could play an important role in shaping life history evolution in Apis mellifera.The aim in this human trial is to compare the efficacy and safety of polygalacturonic–caprylic acid (PG–CAP) ointment to MediHoney in chronic wounds at three international medical centres. In this prospective open-label study, patients with chronic full-thickness wounds were randomised to daily treatment with PG–CAP ointment or MediHoney. Assessments were obtained weekly for 6 weeks. The validated Pressure Ulcer Scale for Healing (PUSH) score was used to track healing. Efficacies were compared using the Wilcoxon rank-sum test for continuous variables and chi-square or Fisher's exact test for categorical variables. Twenty-six patients with chronic wounds were included. Baseline characteristics were comparable between the groups; however, the history of diabetes mellitus was higher in the PG–CAP group (p = 0.011). All 13 PG–CAP patients showed improvement (100%), compared to only 69% of the 13 MediHoney patients (p = 0.023). Half of the failures in the MediHoney arm were associated with death (15%). No failures, adverse events or deaths occurred in the PG–CAP arm. PG–CAP wound ointment is a novel combination of two plant-based compounds that pose minimal risk of promoting antimicrobial resistance, was highly effective for eradicating wound-pathogen biofilms in vitro and promoted chronic wound healing in vivo with minimal inflammatory reactions. Our findings support PG–CAP as safe, noninferior and possibly more effective than MediHoney in healing chronic contaminated wounds.
To explore community dwelling adults' lived experiences of participating in death café in Singapore.
A descriptive phenomenological study with Photovoice.
A purposive sample of community dwelling adults who participated in a community-based death café was recruited for this study. Data was collected through online individual semi-structured interviews. The Colaizzi's six-step descriptive phenomenological analysis was conducted for data analysis.
Twenty community dwelling adults who participated in a death café were recruited. Participants' experiences of the death café were expounded in four themes: appeals of attending death cafés, enabling features of death café, engaging in die-logues, and perceived impacts of death café on everyday lives. The participants were attracted to death cafés for various reasons including curiosity and grief. A comfortable environment, accompanied by open dialogues and refreshments, was credited as enablers for death conversations. Through these ‘die-logues’, the participants had a deeper understanding of death and began engaging in advance planning.
Death cafés provide a supportive environment for individuals to engage in death-related conversations that may not easily occur in daily life. By engaging in conversations about mortality within death cafés, participants are encouraged to take proactive steps towards advance planning.
Findings from this study can guide the development of community-based interventions by highlighting the essential components required for a death café tailored to the Asian context.
This study describes the community dwelling adults' lived experiences of participating in a death café. The findings from this study underscore the role of informal conversations about death as a tool to promote population health based palliative care initiatives such as overcoming death taboos and stimulating advance care planning among community dwelling adults.
The Consolidated Criteria for Reporting Qualitative Studies was used.
Community-dwelling adults participated in the interviews.
Prehospital care, though critical to injury survival, is largely unavailable in many low and middle-income countries, including Cameroon. Lay first responder (LFR) programmes train persons with high injury exposure in first-aid and emergency transport, but stakeholder buy-in from trainees and healthcare workers (HCWs) is essential. To design a context-appropriate prehospital care system, we evaluated barriers and facilitators of implementing a driver-based LFR programme in Cameroon.
In April 2023, we performed a mixed-methods evaluation targeting commercial mototaxi drivers and HCW in Limbe, Cameroon. Drivers were recruited for focus groups through union leaders. Trauma HCW at Limbe Regional Hospital completed Likert surveys and a subgroup completed semistructured interviews. Data collection focused on perceptions, barriers and facilitators of LFR programme implementation. Survey data were summarised using median and IQR. Interviews were recorded, transcribed, translated and analysed with open and axial coding using reflexive thematic analysis.
Overall, 92 mototaxi drivers and 34 HCWs participated in the LFR programme assessment. Among the HCW surveyed, 93% felt mototaxi drivers were capable of training as LFR but only 44% felt that drivers would be able to provide care safely. Interviews identified negative HCW perceptions of drivers, including drivers being uneducated and financially motivated, as key barriers, whereas driver exposure to injury was identified as a facilitator to LFR programme implementation. Driver groups demonstrated a positive perception of LFR training but identified unpaid time spent transporting injured persons as a significant barrier. Both groups described a need for hospital involvement in trainings and bidirectional standardised communication with HCW.
In Cameroon, driver-based LFR may facilitate increased prehospital care but further exploration of possible systems of collaboration that promote long-term success of the programme is required. Specifically, sustainable implementation will need to include clear bidirectional communication guidelines and provide driver incentive commensurate to effort.
To establish the suitability of self-determination theory as a theoretical framework to inform research and design of digital applications for nurses' well-being.
This discursive paper describes the background and core premises of self-determination theory and explains its relevance as a theoretical framework to support research and the design of digital applications to promote nurses' well-being.
Increasing numbers of digital applications are being used by nurses, but few are supported by clearly explicated theoretical frameworks. Self-determination theory focuses on how people's innate psychological needs interact and are influenced by the social environments where they live and work. Given the influence the social environment can have on well-being, self-determination theory is well suited as a theoretical framework to inform research and design of digital applications promoting nurses' well-being.
Stress and burnout impact nurses worldwide, to the detriment of staff well-being, their retention in health services, and provision of patient care. The rapid development and ubiquitous use of digital applications by nurses make researching their effectiveness vitally important if nurses' well being is to be supported. Self-determination theory provides a theoretical framework useful for these applications.
Through the lens of self-determination theory, researchers, digital application designers, and organisations can garner further insights to support digital application development and implementation for the well-being of nurses.
This paper has international relevance and can assist researchers, application designers, and organisations interested in promoting nurses' well-being through understanding the applicability and usefulness of self-determination theory as a theoretical framework for the design of digital applications for nurses' well-being.

IntroductionSickle 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.
MethodsWe 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.
ResultsFrom 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.
ConclusionSCA 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.

Malaria remains a major global health challenge, caused by several Plasmodium species and transmitted via mosquito vectors. Among these, Plasmodium knowlesi is notable for its zoonotic nature, capable of infecting both macaques and humans. The incidence of P. knowlesi infections has been rising, particularly in Southeast Asia, raising public health concerns. However, compared to other Plasmodium species, the biology, pathophysiology, and transmission dynamics of P. knowlesi remain poorly understood. Given the absence of a licensed vaccine and the increasing threat of drug resistance, a deeper understanding of P. knowlesi biology is essential for effective control and management strategies. This study investigates the metabolomic landscape of P. knowlesi across three intraerythrocytic stagesring, trophozoite, and schizont using mass spectrometry-based metabolomics to gain insights into parasite biology. The analysis revealed distinct metabolic profiles, particularly in the ring stage compared to the other two stages. While glycerophospholipid metabolism and sphingolipid de novo biosynthesis emerged as key pathways associated with common metabolites across all stages, phosphatidylserine synthesis was specifically linked to ring-stage-biased metabolites. Notably, CDP-diacylglycerol-inositol 3-phosphatidyltransferase was highlighted as a promising target based on shared and stage-biased metabolites. Collectively, our findings offer a comprehensive metabolomic profile of P. knowlesi blood-stage development, enhancing our understanding of its biology and identifying potential drug targets that could support the development of novel therapeutic strategies against P. knowlesi malaria.To explore first-line managers' experience of guideline implementation in orthopaedic care during the COVID-19 pandemic.
A descriptive, qualitative study.
Semi-structured interviews with 30 first-line nursing and rehabilitation managers in orthopaedic healthcare at university, regional and local hospitals. The interviews were analysed by thematic analysis.
First-line managers described the implementation of guidelines related to the pandemic as different from everyday knowledge translation, with a swifter uptake and time freed from routine meetings in order to support staff in adoption and adherence. The urgent need to address the crisis facilitated guideline implementation, even though there were specific pandemic-related barriers such as staffing and communication issues. An overarching theme, Hanging on to guidelines for dear life, is substantiated by three themes: Adapting to facilitate change, Anchoring safety through guidelines and Embracing COVID guidelines.
A health crisis such as the COVID-19 pandemic can generate enabling elements for guideline implementation in healthcare, despite prevailing or new hindering components. The experience of guideline implementation during the COVID-19 pandemic can improve understanding of context aspects that can benefit organizations in everyday translation of evidence into practice.
Recognizing what enabled guideline implementation in a health crisis can help first-line managers to identify local enabling context elements and processes. This can facilitate future guideline implementation.
During the COVID-19 pandemic, the healthcare context and staff's motivation for guideline recognition and adoption changed. Resources and ways to bridge barriers in guideline implementation emerged, although specific challenges arose. Nursing managers can draw on experiences from the COVID-19 pandemic to support implementation of new evidence-based practices in the future.
This study adheres to the EQUATOR guidelines by using Standards for Reporting Qualitative Research (SRQR).
