While mental health literacy is an important component to successful help-seeking, rural populations often face gaps in both knowledge and service provision. Informed by the Theory of Planned Behaviour and Self-Efficacy Theory, we designed the ‘Skills for Resilience’ as a brief, once-off, community-based educational intervention to increase Irish farmers’ mental health literacy and help-seeking intentions. We adopted a quasi-experimental between (group: intervention and control) and within-group design (time: baseline [T1], immediately post-intervention [T2], and ≥ 1 month post-intervention [T3]). A total of 72 participants (intervention n = 37; control n = 35) were recruited from knowledge-sharing discussion groups. Although recruitment was also open to women, all discussion groups consisted of men. A trained facilitator delivered a discussion lasting between 30 and 90 minutes. Five intervention participants also participated in a qualitative interview after T3. Our results identified intervention participants’ mental health literacy increased significantly at T2 and T3 compared to T1, but did not increase between T2 and T3. Mental health literacy was also significantly greater in the intervention group compared to the control group at T2 and T3. Help-seeking intentions and self-efficacy in seeking mental healthcare also increased significantly at T2 compared to T1, but did not increase between T1 and T3 or T2 and T3. There were no significant changes in outcome measures for the control group at any time point. Through reflexive thematic analysis we identified that the intervention also addressed stigma against mental health (Theme 1) and provided important resources for participants and their community’s present and future coping (Theme 2). At T3, 100% of participants enjoyed the discussion and would recommend the intervention to other farmers. This intervention provides a successful example of integrating the Theory of Planned Behaviour and Self-Efficacy Theory to improve mental health literacy in farmers using a brief, educational intervention.Chronic and non-healing wounds are a global health issue with limited effective treatments. Wound care costs continue to rise, highlighting the need for new therapies. Medicinal plants, particularly African species, show promise for enhancing wound healing. This review analysed 93 studies and identified 37 relevant to wound healing, covering 39 plant species. Ten species were identified for their rich phytochemical content, specifically flavonoids, terpenoids, and alkaloids (plant-derived compounds). These compounds act synergistically, enhancing the wound healing process at each stage. Flavonoids reduce inflammation and support tissue turnover, while terpenoids enhance collagen production and wound closure. Alkaloids offer antimicrobial benefits and support wound contraction. Notable plants include Ageratum conyzoides and Aspilia africana (Asteraceae family); promoting haemostasis by lowering plasma fibrinogen and enhancing platelet-derived growth factors; Withania somnifera (Solanaceae); and Entada africana (Fabaceae), effectively regulating inflammation. In the proliferative phase, Ocimum gratissimum (Lamiaceae), Calendula officinalis (Asteraceae), and Centella asiatica (Apiaceae) although C. officinalis is native to Southern Europe, and C. asiatica an Asian-native; they are widely used in African traditional medicine and included here for their relevance in African wound healing practices; Justicia flava (Acanthaceae), Alternanthera sessilis (Amaranthaceae), and Acalypha indica (Euphorbiaceae); play key roles in enhancing collagen production, angiogenesis, and re-epithelialisation. This comprehensive analysis highlights the role of African medicinal plants in wound healing and their potential to improve wound care therapy.
To demonstrate a worked-out example of a Bayesian independent t-test using open-source software, simulated data, a hypothetical nurse education intervention and a randomised controlled study design. This tutorial explains relevant Bayesian concepts and highlights literature that provides statistically principled justifications for replacing or complementing the frequentist independent t-test with its Bayesian counterpart.
Bayesian t-test analysis tutorial.
A pedagogical framework was applied.
Simulated data generated in Microsoft Excel was uploaded to the Open Science Framework, accessible at: osf.io/4t9gn.
The Bayesian independent t-test in JASP provides: (1) a Bayes factor quantifying the relative evidence for determining which of two competing theories, that is, the null (H0) or the alternative (H1) hypotheses, better supports the experimental data and (2) the posterior probability distribution, with its median point estimate plus a 95% credible interval, quantifying the magnitude and uncertainty of the effect size estimate.
This article provides a practical method for nursing and midwifery researchers to conduct Bayesian analysis, offering statistical, practical and ethical advantages, including the application of sequential analysis and optimal stopping rules enhancing research efficiency.
This article increases awareness of the feasibility and benefits of Bayesian analysis in nursing and midwifery research, emphasising its ease of implementation through open-source software. Clear step-by-step guidance is provided to support its wider adoption and strengthen methodological rigour in nursing and midwifery research.
Nursing and midwifery research has traditionally relied upon frequentist statistical techniques, based on p values and confidence intervals. Bayesian methods can: (a) improve nursing and midwifery decision-making with probabilistic evidence and (b) reduce publication bias by avoiding binary interpretation of research results.
The methodology aligns with van Doorn et al. (2021) guidelines for conducting and reporting a Bayesian analysis.

Transporting critically ill patients between medical facilities can be hazardous and costly. Whether by road, fixed-wing aircraft or helicopter, many professional associations have proposed strategies to efficiently and safely transport patients at high risk of instability. Although these strategies have been assessed in some studies, no comprehensive synthesis of their benefits has been conducted to date. The aim of this study is to assess the effect of strategies to improve the safety and costs of interhospital transports for critically ill patients.
We will conduct a systematic review according to the Cochrane guidelines. The review will include randomised controlled trials (RCTs), cohort studies and case-control studies assessing the effect of interventions to improve interhospital transports of critically ill patients on safety and costs. We will search multiple electronic databases (PubMed, EMBASE, CINAHL, Web of Science, Cochrane Library) from inception to 6 months prior to the submission of the final manuscript. Screening by title and abstract, full-text screening, data extraction and quality assessment will be performed by two independent reviewers. We will assess the risk of bias with the Cochrane revised tool for RCTs and with the risk of bias in non-randomised studies of interventions tool. If possible, we will calculate pooled effect estimates and 95% CIs to assess the effect of the interventions. We will also assess heterogeneity using the I2 index and rate the certainty of evidence with the Grading of Recommendations Assessment, Development and Evaluation tool and trial sequential analysis.
Ethics approval is not required for this review. The results of this systematic review will be shared through publication in a peer-reviewed journal, conference presentations and our network of knowledge user collaborators.

To examine changes in cardiovascular disease (CVD) risk factors, lung function and clinical laboratory markers among people who smoke who used e-cigarettes to reduce their cigarette smoking.
Four-arm, parallel-group, double-blind, randomised placebo-controlled trial.
Two sites—Virginia Commonwealth University (Richmond, Virginia, USA) and Penn State University, College of Medicine (Hershey, Pennsylvania, USA).
Adults (n=520) aged 21–65 years who smoked at least 10 cigarettes per day, had an expired-air carbon monoxide reading of >9 parts per million at baseline and were interested in reducing their cigarette consumption.
E-cigarettes with 0, 8 or 36 mg/mL nicotine liquid concentration or a cigarette substitute.
CVD risk factors (blood lipids, C-reactive protein, blood pressure, heart rate, waist-to-hip ratio, body mass index and INTERHEART risk score), lung function (spirometry indices, and pulmonary symptoms and functional state using the Clinical Chronic Obstructive Pulmonary Disorder Questionnaire), and other clinical laboratory markers (complete blood count and complete metabolic panel).
At 6 months, the use of nicotine e-cigarettes caused no significant between-group differences for most measures. However, participants randomised to the 36 mg/mL e-cigarette condition had significantly higher levels of high-density lipoprotein (HDL) (p=0.003 unadjusted, p=0.002 adjusted) and lower levels of low-density lipoprotein (LDL) (p=0.044 adjusted) and cholesterol/HDL ratio (p=0.034 unadjusted, p=0.026 adjusted) compared with the cigarette substitute condition. Also, those in the 36 mg/mL e-cigarette condition had higher HDL levels than those in the 0 mg/mL condition (p=0.016 unadjusted, p=0.019 adjusted).
Participants randomised to the highest nicotine e-cigarette condition showed modest improvements in some measures of blood lipids (eg, increased HDL, and reduced LDL and cholesterol/HDL ratio) as compared with a non-aerosol cigarette substitute among individuals attempting to reduce their cigarette smoking. Future studies of e-cigarettes for smoking cessation would benefit from including these measures to further explore the results found in this study.
Diabetes related foot ulcers (DFUs) are complex and costly to manage, with the prevalence of non-healing wounds steadily increasing across the globe. Non-healing wounds can occur when clinicians fail to undertake an appropriate assessment, fail to recognise the importance of systemic or local complications, or provide the optimal treatment. The aetiological causes behind non-healing wounds are multifactorial; however, the purpose of this article is to focus on the role of oxygen in non-healing wounds and to introduce readers to advances in the delivery of topical oxygen therapy (TOT) via a haemoglobin spray. Importantly, this article incorporates a clinical decision support tool (CDST) to help clinicians identify the most appropriate individuals for whom topical haemoglobin may be most beneficial and the most appropriate time for introducing the intervention to improve wound healing outcomes.
To investigate risk factors for re-infection and compare the outcomes in people with diabetic foot infections. A retrospective chart review was conducted, and 294 hospitalised patients with moderate to severe diabetic foot infections (DFIs) were analysed for this study. The diagnosis and classification of the severity of infection was based on the International Working Group on the Diabetic Foot (IWGDF) infection guidelines. Skin and soft tissue infections were diagnosed based on clinical observations as per IWGDF classification in addition to ruling out any suspected osteomyelitis (OM) through negative bone culture, MRI or WBC SPECT CT. OM was confirmed by bone culture or histopathology. Clinical outcomes were based on a 12-month follow-up period. All dichotomous outcomes were compared using χ 2 with an alpha of 0.05. The result of this study shows a 48% rate of re-infection in people admitted to our hospital with moderate and severe diabetic foot infections (DFI). Patients with osteomyelitis present during the index admission were 2.1 times more likely to experience a re-infection than patients with soft tissue infection (56.7% vs. 38.0% respectively). In the univariate analysis, risk factors for re-infection included osteomyelitis, non-healing wounds, prolonged wound healing, antidepressants and leukocytosis. In the regression analysis, the only risk factor for re-infection was wounds that were not healed >90 days (HR =2.0, CI: 1.5, 2.7, p = 0.001). Re-infection is very common in patients with moderate and severe diabetic foot infections. Risk factors include osteomyelitis, non-healing wound, prolonged wound healing, antidepressants and leukocytosis.
The objective of this paper was to investigate erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP) in diagnosing pedal osteomyelitis (OM) in patients with and without diabetes, and with and without severe renal impairment (SRI). This was a retrospective cohort study of patients with moderate and severe foot infections. We evaluated three groups: Subjects without diabetes (NDM), subjects with diabetes and without severe renal insufficiency (DM-NSRI), and patients with diabetes and SRI (DM-SRI). SRI was defined as eGFR <30. We evaluated area under the curve (AUC), cutoff point, sensitivity and specificity to characterize the accuracy of ESR and CRP to diagnose OM. A total of 408 patients were included in the analysis. ROC analysis in the NDM group revealed the AUC for ESR was 0.62, with a cutoff value of 46 mm/h (sensitivity, 49.0%; specificity, 76.0%). DM-NSRI subjects showed the AUC for ESR was 0.70 with the cutoff value of 61 mm/h (sensitivity, 68.9%; specificity 61.8%). In DM-SRI, the AUC for ESR was 0.67, with a cutoff value of 119 mm/h (sensitivity, 46.4%; specificity, 82.40%). In the NDM group, the AUC for CRP was 0.55, with a cutoff value of 6.4 mg/dL (sensitivity, 31.3%; specificity, 84.0%). For DM-NSRI, the AUC for CRP was 0.70, with a cutoff value of 8 mg/dL (sensitivity, 49.2%; specificity, 80.6%). In DM-SRI, the AUC for CRP was 0.62, with a cutoff value of 7 mg/dL (sensitivity, 57.1%; specificity, 67.7%). While CRP demonstrated relatively consistent utility, ESR's diagnostic cutoff points diverged significantly. These results highlight the necessity of considering patient-specific factors when interpreting ESR results in the context of OM diagnosis.
Background
The prevalence of short sleep duration is rising and is linked to chronic comorbidities, such as metabolic syndrome (MetS). Sleep extension interventions in adults with MetS comorbidities and short sleep duration are limited and vary widely in terms of approach and duration.
Objectives
This pilot study aimed to test the feasibility and acceptability of a personalized 12-week systematic sleep time extension intervention on post-intervention sleep outcomes in middle-aged adults at risk for MetS with actigraphy-estimated short sleep duration.
Methods
A single-arm, 12-week, 12-session systematic sleep time extension intervention was delivered weekly via videoconferencing. Feasibility and acceptability were assessed using retention rates and mean sleep diary completions. Sleep was estimated for 14 consecutive days prior to and immediately following the 12-week intervention using wrist actigraphy. Daytime sleepiness was assessed using the Epworth Sleepiness Scale. Paired sample t-tests modeled changes in study outcomes.
Results
Study participants (N = 41) had a mean age of 52 years and were mostly female and White; 86% attended >80% of sessions, and mean sleep diary completion was 6.7 diaries/week. Significant improvements in sleep from pre- to post-intervention included increased total sleep time, earlier sleep onsets, more regular sleep onsets, a higher sleep regularity index, and reduced daytime sleepiness. Extending sleep, as well as improving sleep timing and regularity in middle-aged adults with actigraphy-estimated short sleep duration and at risk for MetS, is feasible and acceptable.
Discussion
Behavioral sleep characteristics may be modifiable and present a novel behavioral paradigm for mitigating MetS risk. This pilot study provides a proof of concept for the feasibility, acceptability, and preliminary effectiveness of a systematic sleep time extension for middle-aged adults at risk for MetS with actigraphy-estimated short sleep duration. There is an increasing use of non-medicated wound dressing with claims of irreversible bacterial binding. Most of the data are from in vitro models which lack clinical relevance. This study employed a range of in vitro experiments to address this gap and we complemented our experimental designs with in vivo observations using dressings obtained from patients with diabetes-related foot ulcers. A hydrophobic wound dressing was compared with a control silicone dressing in vitro. Test dressings were placed on top of a Pseudomonas aeruginosa challenge suspension with increasing concentrations of suspension inoculum in addition to supplementation with phosphate buffered saline (PBS) or increased protein content (IPC). Next, we used the challenge suspensions obtained at the end of the first experiment, where bacterial loads from the suspensions were enumerated following test dressing exposure. Further, the time-dependent bacterial attachment was investigated over 1 and 24 h. Lastly, test dressings were exposed to a challenge suspension with IPC, with or without the addition of the bacteriostatic agent Deferiprone to assess the impacts of limiting bacterial growth in the experimental design. Lastly, two different wound dressings with claims of bacterial binding were obtained from patients with chronic diabetes-related foot ulcers after 72 h of application and observed using scanning electron microscope (SEM). Bacteria were enumerated from each dressing after a 1-h exposure time. There was no statistical difference in bacterial attachment between both test dressings when using different suspension inoculum concentrations or test mediums. Bacterial attachment to the two test dressings was significantly lower (p < 0.0001) when IPC was used instead of PBS. In the challenge suspension with PBS, only the hydrophobic dressing achieved a statistically significant reduction in bacterial loads (0.5 ± 0.05 log colony forming units; p = 0.001). In the presence of IPC, there was no significant reduction in bacterial loads for either test dressing. When bacterial growth was arrested, attachment to the test dressings did not increase over time, suggesting that the number of bacteria on the test dressings increases over time due to bacterial growth. SEM identified widespread adsorption of host fouling across the test dressings which occurred prior to microbial binding. Therein, microbial attachment occurred predominantly to host fouling and not directly to the dressings. Bacterial binding is not unique to dialkylcarbamoyl chloride (DACC) dressings and under clinically relevant in vitro conditions and in vivo observations, we demonstrate (in addition to previously published work) that the bacterial binding capabilities are not effective at reducing the number of bacteria in laboratory models or human wounds.
