Introduction

Many patients receive oral anticoagulation for reduced stroke risk in atrial fibrillation or as treatment or prevention of venous thromboembolism. Oral factor Xa inhibitors (oral FXaI, eg, apixaban, edoxaban or rivaroxaban) are commonly prescribed for this indication. Dabigatran, an oral direct thrombin inhibitor, is similarly approved. In vitro and animal model evidence suggests that dabigatran also has direct effects on Staphylococcus aureus virulence and infection. Observational data have shown that dabigatran users are less likely to develop S. aureus bacteremia (SAB), and a small randomised controlled trial showed that dabigatran has anti-S. aureus effects when compared with low molecular weight heparins during bloodstream infection. We seek to answer whether dabigatran is superior to the oral FXaIs in achieving better SAB outcomes among patients who independently require oral anticoagulation. We report the intervention-specific protocol, embedded in an adaptive platform trial.

Methods and analysis

The S. aureus Network Adaptive Platform (SNAP) trial [NCT05137119] is a pragmatic, randomised, multicentre adaptive platform trial that compares different SAB therapies for 90-day mortality rates. For this intervention (‘Dabi-SNAP’), patients receiving therapy with an oral FXaI will be randomised to continue as usual or to change to dabigatran as of the next scheduled dose. All subjects will receive standard of care antibiotics and/or antibiotics allocated through other active domains in the platform. As the choice of anticoagulant may not demonstrate large differences in mortality, a ranked composite of death and adverse outcomes (Desirability of Outcome Ranking, or DOOR) was chosen as the primary outcome.

Ethics and dissemination

The study is conditionally approved by the research ethics board of the McGill University Health Centre: identifier 2025-10900. Trial results will be published open access in a peer-reviewed journal and presented at a global infectious disease conference. The trial is registered at clinicaltrials.gov with the identifier NCT06650501.

CRE-Ter enhances murine bone differentiation, improves muscle cell atrophy, and increases irisin expression

by Sompot Jantarawong, Wipapan Khimmaktong, Pharkphoom Panichayupakaranant, Yutthana Pengjam

Ternary complex of curcuminoid-rich extract (CRE-Ter) is a developed water-soluble Curcuma longa extract containing 14% w/w curcuminoids, hydroxypropyl-β-cyclodextrin, and polyvinylpyrrolidone K30. This study aimed to investigate the biomolecular effects of CRE-Ter on differentiation of bone cells (murine MC3T3-E1 preosteoblasts), muscle cells (murine dexamethasone-treated C2C12 myotubes) atrophy and irisin expression. In MC3T3-E1 preosteoblasts, CRE-Ter treatment increased alkaline phosphatase activity, calcium deposition, and expression of Bmp-2, Runx2, and collagen 1a significantly and dose-dependently. 5, 10, and 20 µg/mL CRE-Ter upregulated β-catenin expression significantly. CRE-Ter improved the atrophy of dexamethasone-treated C2C12 myotubes. CRE-Ter decreased proinflammatory cytokine (TNF-α and IL-6) expression but increased FNDC5 and irisin expression and nitric oxide production in dexamethasone-treated C2C12 myotubes significantly and dose-dependently. Dexamethasone promoted β-catenin and total p38 expression in C2C12 myotubes. CRE-Ter at 2.5–20 µg/mL reversed the increase in β-catenin expression, whereas 2.5 µg/mL reversed total p38 expression. Crosstalk experiments further revealed that conditioned medium from C2C12 myotubes enhanced osteocalcin expression in MC3T3-E1 osteoblasts. Molecular docking simulations using CB-Dock2 showed strong interactions between each curcuminoid molecule and irisin. Therefore, CRE-Ter may stimulate osteoblast differentiation, ameliorate myotube atrophy, and increase irisin expression, indicating its therapeutic potential in osteoporosis, sarcopenia, and osteosarcopenia.

Sub-chronic exposure to crude acetylene results in the development of deleterious cardio metabolic changes in <i>Sprague Dawley</i> rats

by Caroline Gatwiri Gitonga, Charles Githinji, Boniface Chege, Frederick Bukachi, Peter Waweru

Objective

Calcium carbide-derived acetylene is widely used as an artificial fruit ripening agent despite its potential health risks. This study aimed to investigate the effects of sub-chronic exposure to crude acetylene on cardiometabolic parameters using a rodent model.

Methods

Twenty-four male Sprague Dawley rats were randomized into four groups: control (no exposure) and three test groups exposed to 58,000 ppm crude acetylene for 10, 30, or 60 minutes daily over 42 days. Body weight, fasting blood glucose, oral glucose tolerance, hepatic triglyceride levels, adipose tissue mass, liver enzyme activity, and oxidative stress markers were assessed. Histopathological analysis of liver tissue was also conducted.

Results

Acetylene exposure did not significantly alter body weight but led to dose-dependent increases in central adiposity, hepatic triglycerides, and markers of oxidative stress. Higher doses were also associated with impaired glycemic control, elevated liver enzyme levels, and increased free heme concentration in plasma, suggesting oxidative damage and hemolysis. Histological analysis revealed central vein congestion and hepatic structural alterations in exposed groups.

Conclusion

Sub-chronic inhalation of crude acetylene induced metabolic dysfunction characterized by impaired glucose regulation, hepatic steatosis, and oxidative stress, despite no changes in overall body weight. These findings highlight the potential health risks associated with acetylene exposure and underscore the need for regulatory measures to limit its use in fruit ripening.

Knowledge, attitudes, and barriers to HIV testing among youth in Kumba, Cameroon: A cross-sectional qualitative community-based focus group study

by Frederick Nchang Cho, Marie Clarie Fien Ndim, Diane Zinkeng Tongwa, Christabel Afor Tatah, Franklin Ngwesse Ngome, Eugine Mbuh Nyanjoh, Andrew N Tassang

Background

Human Immunodeficiency Virus (HIV) remains a major public health concern in sub-Saharan Africa. In Cameroon, young people are disproportionately affected but underrepresented in HIV testing statistics.

Objective

To explore knowledge, attitudes, and behaviours related to HIV testing among youth in Kumba, Cameroon, and to identify barriers to inform community-based interventions.

Methods

A cross-sectional qualitative study was conducted using nine focus group discussions (FGDs) with 75 youth (52 females and 23 males) aged 18 - 35 years across four quarters in the Kumba II municipality. Participants were purposively sampled to reflect diverse educational and occupational backgrounds. Data were thematically analysed using Braun and Clarke’s framework with NVivo Version 14.

Results

Participants demonstrated high awareness of HIV testing services (90.7%) and transmission via sexual contact (96.0%), though knowledge gaps remained regarding non-sexual transmission and testing procedures. While 93.3% had previously undergone HIV testing, 57.3% reported stigma and 46.7% raised confidentiality concerns as ongoing barriers. Female participants feared being labelled as promiscuous, while males cited social norms that discourage help-seeking. Most participants supported school-based or youth-centred community testing, emphasising the need for privacy and youth-friendly environments. Key motivators for testing included the desire to know one’s status (82.7%), symptom appearance (28.0%), and unprotected sex (17.3%).

Conclusions

Despite strong awareness and high testing uptake, stigma and confidentiality concerns persist among youth in Kumba. To enhance HIV testing rates, community-based strategies should prioritise mobile clinics, peer outreach, and confidential youth-centred services. Strengthening education about HIV transmission and demystifying the testing process may further reduce barriers.

Psychosocial Support Interventions After Perinatal Loss: A Network Meta‐Analysis of RCTs Indicates What Works Best for Women's Mental Health?

ABSTRACT

Background

Psychosocial interventions are recognized as effective nonpharmacological treatments that can enhance the mental well-being of women dealing with perinatal loss. However, as these interventions vary widely, there is currently no review that systematically evaluates and ranks their effects on the mental health of women affected by perinatal loss.

Objective

The aim of this study is to integrate the existing evidence, assess and compare the effects of psychosocial interventions on negative emotions among women experiencing perinatal loss, rank the effect sizes of various interventions, and identify the most effective intervention on the basis of different outcome measures.

Methods

Seven English-language databases were systematically searched for randomized controlled trials (RCTs) focusing on women experiencing perinatal loss, with publications up to August 20, 2024. Traditional pairwise meta-analyses were performed using Review Manager 5.4.1, while Stata 18.0 was employed for network meta-analysis and evidence synthesis. The surface under the cumulative ranking curve (SUCRA) was used to assess the efficacy of the interventions. The protocol was registered with PROSPERO under number CRD42024530312.

Results

A total of 30 RCTs encompassing 6181 participants were included in the analysis. On the basis of the SUCRA rankings, problem-solving therapy was identified as an effective treatment for alleviating depression and anxiety among women experiencing perinatal loss (depression: SUCRA = 82.55%, SMD = −1.34, 95% CI [−2.41, −0.27]; anxiety: SUCRA = 97.7%, SMD = −2.83, 95% CI [−4.26, −1.40]). Additionally, bereavement intervention emerged as the most effective approach for improving grief symptoms (SUCRA = 81.60%, SMD = −1.11, 95% CI [−2.14, −0.09]).

Linking Evidence to Action

Compared with traditional treatment, psychosocial intervention can improve the psychological state of women with perinatal loss, and the differences in the effects of face-to-face and technology-assisted interventions should be further explored. Moreover, problem-solving therapy has proven to be effective and appears to be the most effective method for alleviating depressive and anxiety symptoms among women experiencing perinatal loss, while bereavement support is the most effective method for grief due to perinatal loss. Nursing and health policymakers can develop various intervention strategies according to the varied psychological states of women experiencing perinatal loss.

Mass spectrometry-based metabolomics uncovers distinct metabolic signatures and potential therapeutic targets in <i>Plasmodium knowlesi</i>

by Naphatsamon Uthailak, Sadudee Chotirat, Ammarind Anatjitsupha, Waraporn Thongyod, Phornpimon Tipthara, Jetsumon Sattabongkot, Joel Tarning, Wang Nguitragool, Onrapak Reamtong

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.

Structural Empowerment and Organisational Silence of New Nurses: The Mediating Role of Role Ambiguity

ABSTRACT

Aim

This study aims to assess the extent of organisational silence among new nurses, analyse how structural empowerment and role ambiguity influence this silence, and determine whether role ambiguity mediates the relationship between structural empowerment and organisational silence. The findings intend to offer practical guidance for nursing managers in supporting new nurses by minimising role ambiguity and fostering open communication during the transition into clinical practice.

Background

New nurses commonly exhibit organisational silence during their transition process. Although research indicates that structural empowerment, role ambiguity and organisational silence are interrelated, the underlying mechanisms among these three factors remain unclear.

Design

A cross-sectional design.

Method

A convenience sampling approach was adopted between September 2024 and March 2025. The study recruited 680 new nurses from 15 tertiary A-level hospitals located in Guangzhou, Changsha and Hangzhou. Data collection instruments included a demographic information form, the Chinese version of the Nursing Role Conflict and Role Ambiguity Scale, the Employee Silence Behaviour Questionnaire and the Job Efficiency Conditions Scale. To examine the mediating role of role ambiguity in the relationship between structural empowerment and organisational silence, structural equation modelling (SEM) was applied.

Results

A total of 628 new nurses participated in the survey. Structural empowerment was negatively correlated with role ambiguity (p < 0.01) and organisational silence (p < 0.01). The mediation analysis indicated that role ambiguity partially mediated the relationship between structural empowerment and organisational silence. Specifically, the mediating effect of role ambiguity was –0.14, accounting for 31.11% of the total effect.

Conclusion

This research indicated that new nurses exhibited a below-average level of structural empowerment, while their levels of role ambiguity and organisational silence were above average. Specifically, structural empowerment had a negative impact on both role ambiguity and organisational silence; role ambiguity positively predicted organisational silence. Furthermore, role ambiguity played a significant mediating role in the relationship between structural empowerment and organisational silence.

Impact

The findings indicate that nursing managers should not only focus on enhancing the structural empowerment of new nurses but also strengthen their role awareness, ensuring it plays a key role in reducing levels of organisational silence.

Por: Li · Q. · Tong · H. · Liu · X. · Liao · F. · Ma · H. · Zhou · Z. · Liu · F. · Shi · H. · Wang · Z. · Sun · Y. · Yao · Q. · Feng · Y. · Li · X. · Feng · J. · He · Z. · Peng · Y. · Bai · Z. · Zhu · R. · Cheng · D. · Xu · C. · He · S. · Yu · H. · Xie · C. · Yuan · J. · Wang · X. · Yang · H. · Zou · Y. · Li · S.
Introduction

Hepatic encephalopathy (HE), a severe complication of decompensated cirrhosis, is characterised as neurocognitive dysfunction. Emerging evidence suggests the potential role of human albumin infusion for the treatment of HE, but its optimal dosage remains undefined. Therefore, we planned a randomised controlled trial (RCT) to compare the efficacy of human albumin infusion at different dosages in patients with liver cirrhosis and overt HE.

Methods and analysis

This RCT will be conducted in the Departments of Gastroenterology or Hepatology of 16 tertiary hospitals in China. Overall, 174 patients with a diagnosis of liver cirrhosis, overt HE and a serum albumin level of 23–30 g/L will be enrolled. They will be stratified according to the severity of overt HE and randomly assigned at a ratio of 1:1 into the groups of human albumin infusion at a modified dosage and a routine dosage. The primary end point is the improvement of overt HE within 3–5 days after treatment. The secondary end points include recurrence of overt HE, survival and adverse events. We expect that this RCT will provide high-quality evidence on the optimal dosage of human albumin infused, which can achieve more clinical benefits to patients with liver cirrhosis and overt HE.

Ethics and dissemination

The study has been approved by the Medical Ethical Committee of the General Hospital of Northern Theater Command (ethical approval number Y2024-148). The study findings will be published in academic journals.

NCT06483737.

Applications, Challenges and Strategies of Patient Journey Maps in Care Transitions: A Scoping Review

ABSTRACT

Aim

To synthesise the application, construction methods, challenges, and optimisation strategies of Patient Journey Maps (PJMs) in care transitions.

Design

A scoping review guided by Arksey and O'Malley's framework and PRISMA-ScR.

Data Sources

Nine databases, including PubMed, Embase, CINAHL, Cochrane Library, Web of Science, CNKI, etc., searched from January 2015 to March 2025.

Methods

Two reviewers independently screened studies, extracting data from 23 studies across 12 countries, synthesised via descriptive and thematic analyses informed by nursing theories.

Results

PJMs targeted elderly, children/adolescents, and special-needs populations across in-hospital referrals, inter-hospital transitions, and community adaptation. PJMs development integrated qualitative (interviews, co-design) and quantitative (process mining, EHR analysis) methods to map stages, touchpoints, and emotional curves. Challenges included collaboration breakdowns (78.3%), information fragmentation (74.0%), and psychosocial barriers (47.8%). Optimization strategies emphasised interdisciplinary collaboration, standardised processes, technology enablement, and patient-centred interventions.

Conclusion

PJMs enhance care transitions by visualising patient experiences and systemic gaps, improving continuity and safety. Scalability requires addressing technological adaptation, policy alignment and resource equity. Future research should prioritise dynamic, digitally driven PJM tools and cross-regional collaboration for health equity.

Impact

This review informs clinical practice and policy by bridging theoretical and practical gaps in transitional care via interdisciplinary strategies and technology integration.

Contribution to the Field

Advances global nursing practice with patient-centered strategies, promotes health equity through collaboration, and informs policy and digital innovation for dynamic care transitions.

Injection Techniques to Reduce Adverse Effects of Subcutaneous Low‐Molecular‐Weight Heparin Among Patients With Cardiovascular Diseases: A Scoping Review

ABSTRACT

Aim(s)

To systematically review the existing literature and address the following research question: What are the most effective techniques used to minimise adverse effects resulting from subcutaneous injections of low-molecular-weight heparin among patients with cardiovascular diseases?

Design

A scoping review.

Methods

A comprehensive search was conducted across multiple databases, including CINAHL, PubMed, EMBASE and the Cochrane Library, from 1 February 2014 to 31 January 2024. Participants were aged 18 years or older, diagnosed with venous thromboembolism or arterial thromboembolism and had prescribed subcutaneous injections of low-molecular-weight heparin. The collected data were analysed following the Joanna Briggs Institute approach, and it was organised and categorised based on the main objectives of the review.

Results

Twenty studies were eligible, including 1 best practice project, 7 randomised controlled trials and 9 quasi-experimental studies. The techniques under investigation encompassed various aspects, including the injection site, injection duration (e.g., 30 s vs. 10 s), injection method (e.g., needle insertion angle), duration of needle withdrawal after injection, pressure application time and cold pressure. Preliminary evidence suggests that techniques such as using the abdominal site and slower injection rates may help reduce adverse effects. However, the optimal parameters for injection duration, waiting time, pressure and cold application, including the duration of these applications, remain uncertain due to limitations in sample size and heterogeneity in interventions and outcome measures across the studies.

Conclusions

Ensuring the accurate administration of low-molecular-weight heparin is of utmost importance as it plays a critical role in decreasing mortality rates and minimising substantial healthcare costs linked to complications arising from incorrect administration. The findings from the current review have significantly contributed to strengthening the evidence base in this field, providing more robust and reliable information.

Implications for the Profession

This review emphasises the significance of implementing standardised subcutaneous injection techniques for low-molecular-weight heparin in patients with cardiovascular disease in order to reduce complications and enhance patient outcomes.

Reporting Method

This study followed the applicable guidelines established by the PRISMA 2020 statement. The PRISMA checklist for systematic reviews was utilised for reporting purposes.

Patient or Public Contribution

There is no patient or public contribution to declare.

Return to work with long COVID: a rapid review of support and challenges

Por: Daniels · S. · Wei · H. · McElvenny · D. M. · van Tongeren · M. · Bramwell · D. · Coleman · A. · Forde · D. · Wiggans · R.
Objectives

To explore existing evidence for the provision of support for return to work (RTW) in long COVID (LC) patients and the barriers and facilitators to taking up this support.

Design

A rapid review reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The study was preregistered in PROSPERO (ID: CRD42023478126).

Data sources

Searches were completed in June 2024 across major databases including MEDLINE, Embase, PsycINFO, evidence-based medicine reviews, Web of Science and Google Scholar.

Eligibility criteria

Included studies focused on people with LC (PwLC) symptoms lasting over 12 weeks and addressed either: (1) non-workplace- or workplace-based support for RTW and/or (2) barriers and facilitators to RTW in this population.

Data extraction and synthesis

A quality assessment was conducted using the JBI Systematic Reviews critical appraisal tool. The data were summarised in tabular format and a narrative synthesis.

Results

Twenty-five studies were included. While many studies demonstrated rigorous methodologies and low risk of bias levels, some had high and medium risk levels. Non-workplace-based support was mostly measured quantitatively and included interdisciplinary healthcare programmes, clinical interventions and rehabilitation programmes focusing on pacing and breathing strategies. Compensation and insurance schemes were important funders of these interventions.

Workplace-based support was mostly measured qualitatively. Barriers to the provision of support at organisational level included lack of understanding of LC symptoms, insufficient workplace guidance and educational gaps among managers. Individual barriers included threat of income loss, remote working and disconnection from the workplace. Facilitators for support included recognition and validation of LC and its symptoms, and eligibility for disability benefits associated with work.

Conclusions

RTW is an important outcome of health-related absence and should be systematically recorded in studies of PwLC. The heterogeneity and unpredictability of LC symptoms create challenges for supporting working age populations. Further research is crucial to better understand the specific RTW needs for PwLC and address potential barriers and facilitators to workplace-based support, particularly through interventions, organisational practices and employ-led policies that enable sustained RTW. Consistent guidelines on LC’s definition and disability status may facilitate the provision of support and the development of interventions.

Association of prior history of suicide attempt and disease severity and subsequent suicidal acts among patients with psychiatric disorders in North China: a multicentre prospective study protocol

Por: Wu · J. · Min · J. · Luo · Y. · Li · P. · Li · L. · Ge · Y. · Yun · Y. · Lei · C. · Wang · Q. · Zhou · F. · Yin · Y. · Tong · Y.
Introduction

The suicide risk among discharged psychiatric patients is substantially higher than that among patients with physical diseases and the general population. In China, few cohort studies have investigated suicidal acts in patients discharged from psychiatric facilities, and the factors that convey the risk of post-discharge suicidal acts in this specific population remain unclear. Therefore, we are conducting a prospective multicentre cohort study to investigate the association between suicide attempt history and disease severity in patients with common psychiatric disorders with post-discharge suicidal acts.

Methods and analysis

This study will recruit 3000 inpatients with one of three common psychiatric disorders, namely schizophrenia, bipolar disorder and major depressive disorder, from three hospitals in North China: Beijing Huilongguan Hospital, Tianjin Anding Hospital and the First Hospital of Shanxi Medical University. Participants will include 1500 inpatients with schizophrenia, 900 inpatients with major depressive disorder and 600 inpatients with bipolar disorder. The baseline assessment includes determining whether each recruited patient meets the diagnostic criteria for schizophrenia, major depressive disorder or bipolar disorder using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth edition (DSM-IV) and obtaining details on prior histories of suicide attempts and the severity of the diagnosed disorders using several questionnaires. A 2-year follow-up will be conducted after the recruited patients have been completely assessed. Follow-ups are scheduled at 3, 6, 12 and 24 months after discharge. The primary outcomes are suicidal acts, including suicide attempts and death, that occurred during the follow-up period. A survival analysis will be performed to test for the supposed associations.

Ethics and dissemination

This study was approved by the institutional review boards of Beijing Huilongguan Hospital (2022-67-Science), Tianjin Anding Hospital (2022-47) and First Hospital of Shanxi Medical University (2022-K155). All participants will be required to provide written informed consent before the baseline assessment. The recruitment methods will be explained to potential participants, and their confidentiality will be protected throughout the study. The findings of this study will be disseminated to peer-reviewed scientific journals and conference presentations.

The Mediating Role of Death Coping Between Moral Resilience and Vicarious Posttraumatic Growth Among ICU Nurses

ABSTRACT

Aim

This study aimed to examine the level of vicarious posttraumatic growth among intensive care unit nurses in China and explore the mediating role of death coping ability in the relationship between moral resilience and vicarious posttraumatic growth.

Study Design

A multicentre, cross-sectional study was conducted in accordance with the STROBE guidelines.

Methods

Between January and March 2025, a questionnaire survey was conducted among 666 intensive care unit nurses from nine tertiary Grade A hospitals across five provinces in China. Participants completed three standardised instruments: the Rushton Moral Resilience Scale, the Coping with Death Scale–Short Version, and the Vicarious Posttraumatic Growth Inventory. We used IBM SPSS 27.0 for descriptive statistics, univariate analyses, and correlation analyses, and employed AMOS 27.0 to perform structural equation modelling for testing mediation effects.

Results

Intensive care unit nurses demonstrated a moderate level of vicarious posttraumatic growth. Moral resilience was positively associated with both death coping ability and vicarious posttraumatic growth. Death coping ability was found to play a partial mediating role in the relationship between moral resilience and vicarious posttraumatic growth.

Conclusion

Moral resilience and death coping ability are key factors associated with vicarious posttraumatic growth among intensive care unit nurses. Nurses with stronger moral resilience are more likely to cope constructively with death-related stress, which may support psychological growth in trauma-intensive environments.

Impact

This study highlights the need to enhance intensive care unit nurses' moral and emotional capacities through ethics education, emotional coping training, and institutional support strategies. Strengthening these competencies may foster professional development and mental wellbeing in critical care settings.

Consequences in critically ill patients with prolonged mechanical ventilation after diaphragmatic stimulation techniques: a systematic review and meta-analysis

Por: Tong · S. · Yang · Y. · Li · Y. · Liu · L. · Chang · W.
Objective

Prolonged mechanical ventilation (MV) may lead to poor outcomes. This systematic review and meta-analysis aimed to investigate the effects of diaphragmatic stimulation on the duration of MV (DMV), the intensive care unit (ICU) length of stay (ILOS), the proportion of patients successfully weaned and maximum inspiratory pressure (MIP) in patients with prolonged MV.

Design

Systematic review and meta-analysis.

Data sources

Cochrane library, Embase, Pubmed and Web of Science up to December 2024.

Eligibility criteria for selecting studies

Randomised controlled trials (RCTs) and cohort studies evaluating the outcomes of patients with prolonged MV after diaphragmatic stimulation were included up to December 2024.

Data extraction and synthesis

All articles were independently assessed by two reviewers, and a third reviewer was consulted to resolve different evaluations. Newcastle-Ottawa Scale (NOS) and the Cochrane Collaboration tool in RevMan V.5.3 software (The Cochrane Collaboration, 2014) were applied to assess the quality of cohort studies or RCTs. The meta-analysis was carried out with RevMan V.5.3 software, applying a random-effects model and presenting results with 95% CIs. Heterogeneity was examined using the Higgins I² statistic, and subgroup analyses were carried out to investigate possible contributors to heterogeneity. Sensitivity analyses were further conducted in Stata 18.0 (StataCorp LP, College Station, TX, USA). Potential publication bias was assessed through funnel plots combined with Egger’s regression test. For each outcome, the certainty of evidence was appraised according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE).

Results

Ten studies involving 802 patients (349 received diaphragmatic stimulation) were included. The meta-analysis indicated that patients receiving diaphragmatic stimulation had shorter DMV (mean differences (MD) –5.69 d, 95% CI –10.99 to –0.39, p=0.04) and ILOS (MD –5.48 d, 95% CI –10.72 to –0.24, p=0.04). The proportion of patients successfully weaned was larger in patients with diaphragmatic stimulation (risk ratios (RR) 1.25, 95% CI 1.01 to 1.53, p=0.04). The MIP increased compared with the control group.

Conclusions

The promising results suggest that diaphragmatic stimulation has the potential to shorten DMV and ILOS and accelerate weaning from ventilator.

Comparison of diagnostic yield and safety of three endobronchial ultrasound-guided transbronchial biopsy techniques in diagnosing patients with mediastinal/hilar lymphadenopathy: a protocol of multicentre randomised trial in China

Por: Deng · M.-m. · Yang · Z. · Zhong · C. · Zheng · Z. · Tong · R. · Zhou · G. · Li · X. · Zhao · L. · Herth · F. J. F. · Hou · G.
Introduction

Mediastinal and/or hilar lymphadenopathy (MHL) is increasingly identified owing to various underlying conditions. Minimally invasive biopsy techniques, including endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), transbronchial mediastinal cryobiopsy (TBMC) and transbronchial forceps biopsy (TBFB), are common diagnosis tools. However, their safety and diagnostic efficiency remain unclear. This trial aims to compare the diagnostic yield and safety of these three techniques.

Methods and analysis

This study is a three-arm, parallel-design, randomised controlled trial involving 972 adult patients with MHL recruited from multiple medical centres. Participants will be randomly assigned to the EBUS-TBNA, TBMC via a tunnel or TBFB via a tunnel group. The primary outcome is diagnostic yield, and the secondary outcomes include diagnostic sensitivity, sample quality and procedure-related complications. Statistical analyses will be conducted using the appropriate methods. An independent sample ² test will be used to test the differences in the diagnostic yield and incidence of procedure-related complications.

Ethics and dissemination

Ethics approval was obtained from the China-Japan Friendship Hospital Ethics Committee (2022-KY-194).

Written informed consent will be obtained from all patients or their guardians before their enrolment in the study. This study will be conducted per the principles established in the Declaration of Helsinki and the International Council for Harmonisation Guidelines for Good Clinical Practice.

Anticholinergic burden and clinical outcomes among older adults admitted in a tertiary hospital: a prospective cohort study

by Pornkamol Tiranaprakij, Sahaphume Srisuma, Krongtong Putthipokin, Sirasa Ruangritchankul

Background

Anticholinergic medication use is associated with adverse clinical outcomes, especially in older adults. However, few studies have assessed the anticholinergic burden in the Thai geriatric population. Hence, we aimed to evaluate the impact of anticholinergic burden on clinical outcomes in older patients after discharge from the hospital.

Methods

A prospective cohort study was conducted between January 1 to December 31, 2023. The prescribed medications were assessed at admission and discharge to determine the anticholinergic cognitive burden (ACB) scores. Participants were classified into three groups according to the ACB score at discharge: none (score 0), moderate (score 1–2), and severe (score ≥ 3) anticholinergic burden. The Cox proportional hazard model was used to determine the marker risk of high anticholinergic burden to adverse outcomes.

Results

This study involved 290 older patients admitted to general internal medicine wards. At discharge, 37.9% (n = 110) of the patients had a high anticholinergic burden (ACB score ≥ 3), and 50% (n = 145) had a higher ACB score than at admission. The three most commonly prescribed anticholinergics at discharge were benzodiazepines (20.3%), corticosteroids (20.0%), and antihistamines (15.9%). During the one-year follow-up period, 16.6% (n = 48) of the patients died. The incidence rate of all-cause mortality in hospitalized older patients with an ACB score ≥ 3 was 0.65 cases per 1000-person day during a one-year follow-up period. After adjusting for potential factors, an ACB score of ≥ 3 at discharge was marginally associated with one-year mortality post discharge [hazard ratio: 2.98, 95% confidence interval (0.96–9.28)].

Conclusions

The exposure to high anticholinergic burden (ACB scores ≥ 3) at discharge was slightly associated with an increased risk of one-year mortality post discharge. The cautious use of benzodiazepines may assist to reduce the anticholinergic burden in this vulnerable population.

Background

Despite advances in HIV care, viral load suppression (VLS) among adolescents living with HIV (ALHIV) in Uganda continue to lag behind that of adults, even with the introduction of dolutegravir (DTG)-based regimens, the Youth and Adolescent Peer Supporter (YAPS) model, and community-based approaches. Understanding factors associated with HIV viral load non-suppression in this population is critical to inform HIV treatment policy. This study assessed the prevalence and predictors of viral load non-suppression among ALHIV aged 10–19 years on DTG-based ART in Soroti City, Uganda.

Methods

We conducted a cross-sectional study among 447 ALHIV attending three urban HIV clinics in Soroti City. Data were abstracted using a structured questionnaire and analyzed in STATA 15.0. Modified Poisson regression with robust error variance was used to identify predictors of viral load non-suppression. Adjusted relative risks (aRR) and 95% confidence intervals (CIs) were reported, with statistical significance set at p ≤ 0.05.

Results

Of the 447 participants, 53.5% were female, with a median age of 16 years (IQR: 14.0–17.6). The majority (72.9%) were from Soroti district and had been on DTG-based ART for a median of 42.5 months (IQR: 37.0–48.0). Most were receiving multi-month dispensing (MMD) (75.2%) and were active in care (98%). The prevalence of viral load non-suppression was 19.2% (86/447). Independent predictors of non-suppression included older age (15–19 vs. 10–14 years) (aRR: 1.69; 95% CI: 1.08–2.67), male sex (aRR: 1.48; 95% CI: 1.05–2.11), prior non-suppression before switching to DTG (aRR: 1.76; 95% CI: 1.19–2.59), use of non-fixed dose DTG regimens (aRR: 2.03; 95% CI: 1.23–3.33), history of poor adherence (aRR: 4.36; 95% CI: 2.05–9.26), and not receiving MMD (aRR: 2.83; 95% CI: 1.93–4.15).

Conclusion

Nearly one in five adolescents on DTG-based ART in Soroti City had viral non-suppression, despite optimized treatment regimens. Targeted interventions−particularly enhanced adherence counseling for older and male adolescents, expanding MMD coverage, and provision of fixed-dose regimens−are urgently needed to improve VLS among ALHIV. These findings underscore the need for adolescent-centered HIV care strategies to close the viral suppression gap and advance progress towards epidemic control.

Interventions for Improving Coping Strategies in Older Adults: A Systematic Review and Meta‐Analysis

ABSTRACT

Background

Physiological, psychological, and social changes may make older adults more vulnerable to stressors and lead to adverse health outcomes. It remains unclear whether interventions targeting coping strategies in older adults are effective.

Aims

This study aimed to systematically review and summarize existing interventions aimed at improving coping strategies in older adults and analyze intervention effectiveness.

Methods

A systematic search was conducted using PubMed, EMBASE, Web of Science, Cochrane, CINAHL, PsycINFO, CNKI, SinoMed, VIP, and WanFang databases for randomized controlled trials (RCTs) and quasi-experimental studies. Two researchers independently performed literature screening, quality assessment, and data extraction.

Results

A total of 9 studies were included, comprising 7 RCTs and 2 quasi-experimental studies. Meta-analysis revealed that the interventions significantly enhanced the use of problem-focused coping strategies among older adults (SMD = 0.37, 95% CI: 0.12 ~ 0.63, p = 0.005, I 2 = 39%). However, there was no significant effect on emotion-focused coping strategies (SMD = −0.07, 95% CI [−0.62, 0.48], p = 0.80, I 2 = 76%). Moreover, no significant statistical differences were observed between the intervention group and the control group in terms of positive (SMD = 1.49, 95% CI [−0.23, 3.21], p = 0.09, I 2 = 98%) or negative coping strategies (SMD = −0.76, 95% CI [−1.79, 0.28], p = 0.15, I 2 = 96%).

Linking Evidence to Action

Interventions targeting coping strategies can significantly improve the problem-focused coping strategies of older adults. It is crucial to help older adults accurately recognize daily stressors, acquire emotional regulation strategies, and enhance coping skills. More large-scale RCTs are needed to draw more robust conclusions.

Introduction

Diabetes is a significant modifiable risk factor for cognitive dysfunction. There are currently no effective treatments that delay or reverse the progression of cognitive dysfunction. Accumulating evidence demonstrates that specific antidiabetes medications hold promise in improving cognitive function. However, the comparative effects of various antidiabetic drug classes on cognitive protection remain to be fully elucidated. This study aims to investigate and compare the cognitive benefits of liraglutide, empagliflozin and linagliptin on achieving mild cognitive impairment (MCI) remission in individuals with type 2 diabetes (T2D).

Methods and analysis

The LIGHT-MCI trial is an investigator-initiated, multicentre, open-label, parallel-group, randomised, superiority trial involving T2D patients with MCI, consisting of a 48-week core study followed by an extension phase through to 76 weeks. A total of 396 participants will be randomly allocated 1:1:1 to receive liraglutide, empagliflozin or linagliptin treatment. The primary outcome measure is the efficacy difference of liraglutide, empagliflozin and linagliptin in achieving MCI remission in individuals with T2D. The key secondary outcome measures include changes in scores of general cognition and various cognitive subdomains (including processing speed, executive function, immediate memory, visuospatial construction ability, language, attention and delayed memory), basic and instrumental daily living ability, MRI-derived normalised measures of total brain volume, cerebral microstructures, cortical and nuclear volume, white matter hyperintensity, volume, white matter microstructural integrity, odour-induced brain activation and resting-state functional connectivity, olfactory function and metabolic parameters.

Ethics and dissemination

The LIGHT-MCI trial has received approval from the Ethics Committees of the Drum Tower Hospital Affiliated to Nanjing University Medical School (2022-092-02) and other participating centres in accordance with the principles of the Declaration of Helsinki and the International Conference on Harmonisation for Good Clinical Practice (ICH GCP E6). Informed consent is required for participation. Findings from this trial are disseminated through peer-reviewed publications, conference presentations, newsletters and social media.
