Impaired dynein function preserves spinal interneuron survival and positioning in an ALS-like mouse model

by Eleni Christoforidou, Jordan S. Rowe, Fabio A. Simoes, Raphaelle Cassel, Luc Dupuis, Peter Nigel Leigh, Majid Hafezparast

Impaired cytoplasmic dynein function has been implicated in amyotrophic lateral sclerosis (ALS) pathogenesis, yet the contributions of spinal interneurons to disease phenotypes remain unclear. We tested the hypothesis that hypomorphic dynein function in cholinergic neurons disrupts the development, survival, or positioning of inhibitory interneuron populations in the lumbar spinal cord. Using ChAT-Cre recombination, we generated four mouse genotypes with graded reductions in dynein activity in ChAT+ cells: Dync1h1+/+ (wildtype), Dync1h1−/+ (hemizygous wildtype), Dync1h1+/Loa (heterozygous Loa mutation), and Dync1h1−/Loa (hemizygous Loa). At 52 weeks of age, lumbar spinal cords (L3–L6) were harvested, cryosectioned, and immunostained for ChAT, GAD-67, Parvalbumin, and Calbindin. Cell counts were performed on confocal images from eight sections per mouse (N = 3 male mice/genotype), and radial distances from the central canal were normalised to gray matter width. Angular distributions were analysed via circular statistics. There were no significant genotype-dependent differences in the numbers of ChAT+, GAD-67+, Parvalbumin+, or Calbindin+ cells, nor in ChAT+ subpopulations (motor neurons versus interneurons) or double‐positive interneuron subsets (e.g., ChAT+–GAD-67+, Parvalbumin+–GAD-67+, Parvalbumin+–Calbindin+). Radial positioning relative to the central canal was similarly preserved across all markers and genotypes. Circular‐median tests revealed statistically significant shifts in mean angle for ChAT+, GAD-67+, and certain double‐positive cells, but these amounted to only 5–10° displacements, translating to lateral shifts of ~10–20 µm, well within single laminar bands, and are unlikely to impact circuit connectivity. Despite substantial motor deficits and hallmark TDP-43 pathology previously seen in these models, impaired dynein function does not precipitate interneuron loss or gross migratory defects in the lumbar spinal cord. Instead, our findings suggest that the primary contributions of dynein to ALS-like phenotypes likely arise from functional disruptions in axonal transport, synaptic maintenance, and neuronal physiology rather than from structural alterations or loss of interneuron populations.

Availability and affordability of essential medicines for non-communicable disease management in primary healthcare: Evidence from three municipalities in Ghana

by Mary Yeboah, Richard Abeiku Bonney, Loretta Adu-Boahemaa Antwi, Pius Amponsah Anane, Obed Kwabena Offe Amponsah, Peter Agyei-Baffour

Background

Non-communicable diseases (NCDs) cause 74% of global deaths, disproportionately affecting LMICs like Ghana. Chronic treatment remains hindered by medicine shortages and high costs, consuming over 50% of the minimum wage incomes. Despite Ghana’s NCD policies, supply chain gaps and price inflation persist. This study assesses access to medicine, operationally defined as availability and affordability, in three municipalities to inform reforms for Universal Health Coverage and achieve SDG 3.4 targets.

Methods

This cross-sectional mixed study assessed the availability and affordability of NCD medicines in three municipalities in Ghana using WHO/HAI methods. Data on 62 medicines were collected from nine health facilities, supplemented by interviews with pharmacy managers.

Results

This study assessed access to NCD medicines across three municipalities in Ghana, revealing stark disparities. Availability varied significantly by location (Oforikrom 70% vs. Juaben 48.6%, p  Conclusion

This study highlights inequities in access to NCD medicines in Ghana, with stark gaps in availability and affordability, especially in underserved areas. Findings reveal high costs, stock-outs, and geographic disparities as key factors, underscoring the need for supply chain reforms, price regulation, and municipal oversight to advance equitable, sustainable, universal health coverage.

Nurse Practitioner Students' Perceptions of an Artificial Intelligence Differential Diagnosis Tool: A Pilot Study

ABSTRACT

Aim

The aim of this study is to assess nurse practitioner students' perceptions and engagement with Isabel's artificial intelligence (AI) based differential diagnosis tool to support their decision-making skills during their theoretical and clinical placement training.

Design

This pilot study used a cross-sectional design.

Methods

Twenty-six nurse practitioner students provided feedback on their use of an AI differential diagnosis tool in both academic and clinical contexts. This survey used the Post-Study System Usability Questionnaire to assess the engagement levels and usability of the AI tool. Additional questions were included to evaluate the usage patterns, adequacy in training and confidence in diagnosis.

Results

There were mixed engagement levels: 44.4% (n = 8/18) used Isabel in two subjects—typically one or both clinical placement units—and 27.8% (n = 5/18) in one subject; students most often used the tool to confirm differential diagnoses. Usability was rated positively with the disease ranking, red flag diagnosis and link to national guideline features demonstrating the highest student usage. While most students found the tool beneficial to use during clinical placement and completing university assignments, some reported challenges due to insufficient training, impacting confidence in clinical application.

Conclusion

Isabel has potential as a valuable educational tool in Nurse Practitioner programs, but successful implementation depends on adequate training and support. The findings highlight the importance of comprehensive training and support to maximise AI tool utilisation, with direct implications for programme curricula, clinical education strategies and potential improvements in diagnostic reasoning skills for future nurse practitioners.

Implications for the Profession and/or Patient Care

This study provides an example of integrating artificial intelligence (AI) guided clinical decision-making training in nurse practitioner (NP) education. The findings can be used by educational institutions to trial similar AI-integrated learning approaches, enhancing diagnostic competence and potentially improving patient care outcomes.

Reporting Method

The Study adhered to the STROBE checklist for reporting.

Deployment of Perioperative Nurses From Their Clinical Specialty During the COVID‐19 Pandemic: An Integrative Review

ABSTRACT

Aim

To identify the available records surrounding the deployment of perioperative nurses into differing clinical settings during the COVID-19 pandemic.

Design

Integrative review methodology.

Methods

Quality appraisal of each record was conducted using a modified Critical Appraisal Skills Programme checklist. Data were extracted and presented based on outlined research objectives.

Data Sources

Six electronic databases (CINAHL Plus, Google Scholar, MEDLINE, Pubmed, Scopus, and Web of Science) were searched, with relevant peer-reviewed records published after 2019 until February 2025 included to differentiate from other respiratory pandemics.

Results

Ten records were included in the review. Opposing discourse exists between perioperative decision makers and those perioperative nurses who underwent deployment to differing clinical areas surrounding perceptions and experiences of deployment during the COVID-19 pandemic.

Conclusion

Few studies exist exploring experiences of perioperative nurse deployment to a different clinical area during the COVID-19 pandemic. Further research is vital to develop strategies that enhance the deployment process and ensure effective patient care across various clinical settings when cared for by deployed perioperative nurses.

Implications for the Profession and/or Patient Care

Further research exploring transferable perioperative nursing skills and its subsequent influence on safe patient care may enhance and inform nurse deployment practices, enriching future staffing protocols in the event of a future pandemic.

Reporting Method

PRISMA guidelines for reporting systematic reviews guided this review.

Patient or Public Contribution

This study did not include patient or public involvement in its design, conduct, or reporting.

Caring beyond the procedure: a qualitative study on thoracic surgery nurses perspectives on chronic illness experiences of individuals with myasthenia gravis undergoing thymectomy

Por: Missel · M. · Donsel · P. O. · Nielsen · T. F. · Secher · E. L. · Medeiros · E. B. Z. · Rude · K. · Hojgaard · J. L. S. · Viby · N.-E. · Birnbaum · S. · Andersen · L. K. · Petersen · R. H. · Witting · N.
Objectives

To explore how thoracic surgical nurses perceive and respond to the chronic illness needs of individuals with myasthenia gravis undergoing thymectomy.

Methods

Data were collected through four focus group interviews using a semi-structured interview guide. The analysis followed a hermeneutic approach, identifying recurring themes through iterative interpretation and critical reflection. Nineteen thoracic surgical nurses from ward and postanaesthesia care unit settings participated, representing a diverse range of clinical experience. The study followed the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist for reporting the findings of this study.

Results

The analysis identified three overarching themes reflecting nurses’ experiences of caring for individuals with myasthenia gravis undergoing thymectomy. First, nurses described how the chronic aspects of the illness often ‘disappeared’ within the surgical care process, with attention focused mainly on procedural recovery, leaving patients’ broader illness needs unaddressed. Second, nurses experienced a dilemma between providing acute surgical care and responding to patients’ chronic illness understanding, highlighting uncertainty due to limited knowledge and lack of clear guidelines. Third, nurses emphasised the difficulty of managing the invisible and unpredictable symptoms of myasthenia gravis, which created a heightened need for vigilance but also uncertainty in symptom assessment and support. Across all themes, the findings suggest that surgical care practices may insufficiently recognise patients’ ongoing illness experiences, emphasising the need for greater knowledge, interdisciplinary collaboration and chronic illness-sensitive care approaches.

Conclusions

The study highlights the need for increased attention to chronic illness needs in surgical care, supporting interdisciplinary collaboration and tailored nursing practices that address the lived experiences of patients with chronic conditions.

Care Needs for Patients Screened Positive for Cognitive Impairment and Delirium: A Cross‐Sectional Observational Study

ABSTRACT

Aim

To describe the point prevalence of cognitive impairment in hospitalised adults and evaluate the association with care needs and perceived risks of complications.

Design

Multi-site cross-sectional study on a single day in May 2023.

Methods

Trained clinician auditors screened adult inpatients in acute medical, surgical, oncology, geriatric, mental health, convalescent, and rehabilitation wards for cognitive impairment using the 4AT in seven healthcare facilities and recorded need for support with basic activities of daily living, incontinence, and perceived risks of complications (falls, pressure injuries, and malnutrition). Data were summarised and compared across 4AT categories, and the strength of association between 4AT and each outcome was estimated using multivariable regression models.

Results

Data were available for 1145 inpatients on 68 wards (mean age 68 years [SD = 18], 583 [58.9%] female, 449 [39.2%] on acute medical units). Cognitive impairment (4AT of 1 or more) was identified in 482 (42.1%) participants. Participants with 4AT 1–3 had 2.0–3.6 times the odds of need for supervision or assistance with activities of daily living, while those with 4AT 4 or more had 2.9–5.3 times the odds of need for assistance.

Conclusion

Cognitive impairment is very common in adult inpatients and is associated with significantly higher physical care needs.

Implications for the Profession and Patient Care

Hospital care models must support staff to address the higher care needs in people with cognitive impairment to protect a large patient group from hospital-acquired harm.

Patient or Public Contribution

No patient or public contribution.

Computational frameworks for automated detection and quantification of paroxysmal sympathetic hyperactivity among traumatic brain injury patients

by Xiangxiang Kong, Lujie Karen Chen, Sancharee Hom Chowdhurry, Ryan B. Felix, Shiming Yang, Peter Hu, Neeraj Badjatia, Jamie Erin Podell

Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that occurs in a large subset of critically ill traumatic brain injury (TBI) patients and is associated with complications and poor recovery. PSH is defined by recurrent episodic vital sign elevations in the appropriate clinical context. However, standard diagnostic criteria rely heavily on subjective judgment, leading to challenges and delays in recognition, monitoring, and management. The objective of this study was to develop automated PSH detection and quantification tools that exclusively utilize objective bedside continuous vital sign data. Using a cohort of 221 critically ill acute TBI patients with at least 14 days of continuous physiologic data (of which 107 were clinically diagnosed with PSH) we developed a high-resolution clinical feature scale based on established PSH-Assessment Measure criteria and two artificial intelligence-based episode detection models including an expert system approach and a machine learning model approach, using a clinician-annotated case example as ground truth. For the episode detection methods, PSH was quantified as the number, duration, and overall temporal burden of detected episodes. To evaluate performance, we compared quantifications across PSH cases and controls and explored precision and recall. All three methods demonstrated initial face validity to delineate PSH cases from non-PSH TBI controls. Future optimization and implementation of the described computational frameworks with real-time patient data could improve the standard monitoring and management of this challenging clinical syndrome.

Population-based study of pharmacogenetics and pharmacokinetics in Southern African patients with multidrug-resistant tuberculosis (PoPG): a protocol for the Namibian cohort

Por: Boois · L. · Ekandjo · H. · Shavuka · O. · Nepolo · E. · Ndong Sima · C. A. · Oelofse · C. · Uren · C. · Petersen · D. C. · Möller · M. · Wijk · M. · Kellermann · T. · Decloedt · E. · McIlleron · H. · Denti · P. · Claassens · M. M.
Background

Multidrug-resistant tuberculosis (MDR-TB) is an urgent public health challenge in Namibia, with profound socioeconomic consequences. The high burden of both tuberculosis and HIV complicates treatment and underscores the need for optimised drug therapies. Precision medicine, which leverages patient-specific genetic and molecular information, offers promise for improving MDR-TB outcomes. However, its effective application relies on population-specific data, particularly understanding how individuals metabolise tuberculosis drugs and how genetic diversity drives variability in treatment response. Currently, no pharmacokinetic (PK) or pharmacogenetic (PG) data on TB treatment exist for Namibian populations. This gap is particularly concerning, given the country’s genetic diversity, environmental factors and comorbidities that may uniquely influence drug metabolism. This study aims to generate PK and PG data to inform dose optimisation and support personalised treatment strategies for MDR-TB in Namibia. The findings will contribute to improved patient care and inform health system strengthening based on locally relevant evidence.

Methods

This cross-sectional study will consist of 100 Namibian participants with matched human DNA and PK data of MDR-TB cases receiving isoniazid, clofazimine, bedaquiline and the fluoroquinolones (levofloxacin or moxifloxacin). PK sampling will be divided as follows: 30 individuals will undergo intensive PK sampling, while the remaining (n=70) will undergo sparse PK sampling. DNA will be extracted at Stellenbosch University (SU), and samples will be genotyped using the H3Africa microarray. Sequences will be aligned to the human reference genome, hg38 (GRCh38p13), using the freely available Burrows-Wheeler Aligner. A subset of the samples (n=20–30) will undergo whole genome sequencing (WGS) to verify imputation results and identify novel genetic variants potentially affecting PK in this population.

Data analysis

Quality control and variant call format file generation will be performed using the Genome Analysis Toolkit best practices (V.3.5). Intensive and sparse PK data will be pooled for the development of a population PK (popPK) model using a non-linear mixed-effects modelling approach. The popPK model will characterise the relationship between TB drug dose and exposure, including quantifying covariates, including genetic variation, explaining PK variability, providing a foundation for dose optimisation and personalised treatment strategies.

Ethics and dissemination

Ethics approval was obtained from the University of Namibia Human Research Ethics Committee for Health (Ref. SOM18/2024), the Ministry of Health and Social Services (Ref. 22/4/2/3), the SU Health Research Ethics Committee (Ref. N21/11/136) and the University of Cape Town Human Research Ethics Committee (Ref. 500/2022).

Cognitive Impairment in People With Diabetes‐Related Foot Ulcers: A Multicentre, Case–Control, Observational Study

ABSTRACT

Cognitive impairment is associated with people with diabetes-related foot ulcers (DFU). However, it is unclear if cognitive impairment is associated with the ulcer itself or other co-existing diabetes-related complications such as peripheral neuropathy. We aimed to investigate cognition in people with diabetes-related peripheral neuropathy and compare those with DFUs to those without DFUs. In this age- and sex-matched, multicentre, case-control, observational study of 89 participants with Type 2 diabetes and peripheral neuropathy, we compared 49 participants with DFUs (cases) to 40 without DFUs (controls). Global cognition scores were assessed using the Montreal Cognitive Assessment tool. Participants with DFUs had similar characteristics to those without DFUs (all, p > 0.05), except for lower body mass index (p = 0.028). Participants with active DFUs had significantly lower global cognition scores compared to those without DFUs (median [IQR] 24.0 [21.0–25.0], 26.0 [24.0–28.0]; p < 0.001). After adjusting for other diabetes-related complications, lower global cognition was independently associated with a DFU, peripheral artery disease, lower physical activity and no family history of diabetes (all, p ≤ 0.019). People with DFUs had lower cognitive scores than those without DFUs, suggesting that the DFU itself is independently associated with cognitive impairment. Future studies should explore causal pathways and targeted management strategies.

Analgesic efficacy of peri-operative methadone in orthopaedic surgery: protocol for a systematic review of randomised controlled trials

Por: Evaldsson · B. B. · Nygaard · K. H. · Petersen · S. R. · Moos · C. M. · Stroem · T. · Specht · K. · Schonnemann · J. O.
Introduction

Optimising post-operative pain management is crucial for recovery in orthopaedic surgery. Methadone has attracted interest due to its long half-life, N-methyl-D-aspartate -receptor antagonism and potential to reduce post-operative opioid consumption. Existing reviews combine multiple surgical populations, limiting applicability to orthopaedic settings. This protocol outlines a systematic review assessing the analgesic efficacy and safety of peri-operative methadone in adult and adolescent orthopaedic patients.

Methods and analysis

This review will include randomised controlled trials evaluating intravenous peri-operative methadone vs placebo or standard analgesic regimens in orthopaedic surgery. Primary outcomes are post-operative rescue opioid consumption and pain intensity within 72 hours. Secondary outcomes include adverse events, mobility scores and the length of hospital stay. If available data permit, a methadone dose–response pattern may be investigated. Searches will be conducted in MEDLINE (Ovid), Embase (Ovid), CINAHL, CENTRAL, Web of Science and ClinicalTrials.gov without date restrictions. Two reviewers will independently screen studies, extract data and assess risk of bias using the Cochrane risk-of-bias tool for randomised trials. When appropriate, random-effects meta-analysis methods will be performed. Certainty of evidence will be assessed using Grading of recommendations assesment, development and Evaluation (GRADE).

Ethics and dissemination

As this study uses previously published data, ethical approval is not required. Findings will be disseminated through a peer-reviewed publication and conference presentations.

Chrysin ameliorates methotrexate-induced hippocampal neurogenesis impairment by suppressing of oxidative stress and upregulating antioxidant enzyme activity in rodents

by Tanaporn Anosri, Soraya Kaewngam, Ram Prajit, Kornrawee Suwannakot, Nataya Sritawan, Anusara Aranarochana, Wanassanan Pannangrong, Jariya Umka Welbat, Peter Wigmore, Apiwat Sirichoat

Methotrexate (MTX) is used in treating several malignancies. However, MTX neurotoxicity remains a significant clinical side effect, leading to cell division malformation, and neurogenesis impairment. Chrysin, a flavonoid compound found in natural products, demonstrates various biological characteristics, including neuroprotective and antioxidant properties. The purpose of this study was to investigate the ameliorative effect of chrysin on oxidative damage and neurogenesis impairment caused by MTX. Male Sprague-Dawley rats were randomly divided into four groups, including the vehicle, MTX (75 mg/kg), chrysin (10 mg/kg), and chrysin+MTX groups. Chrysin was orally administered for 15 days. MTX was administered intravenously on days 8 and 15. The hippocampal neural stem cells were evaluated using sex determining region Y-box 2 (sox2) and nestin immunofluorescence staining. Antioxidant enzyme expression and the levels of oxidative stress marker were assessed. Additionally, the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), brain-derived neurotrophic factor (BDNF), cAMP-response element binding (CREB), and phosphorylated CREB (pCREB) were evaluated using Western blotting. Results showed that MTX significantly decreased the activity of antioxidant enzymes and produced oxidative stress. MTX also impaired neurogenesis, evidenced by decreased sox2 and nestin-positive cells and decreased expression of Nrf2, BDNF, CREB, and pCREB in the hippocampus and prefrontal cortex. However, chrysin significantly reversed the effects of MTX on these parameters. In conclusion, chrysin exhibits neuroprotective effects against MTX-induced neurogenesis impairment by upregulating antioxidant enzyme activity, reducing oxidative stress, and improving protein expression related to neurogenesis.

Advanced Nursing Roles for People With Cognitive Impairment and Their Relatives in Acute Care Hospitals: A Systematic Review

ABSTRACT

Aim

To systematically review advanced nursing roles in caring for people with cognitive impairment and their relatives in acute care hospitals, focusing on describing roles and intervention components.

Design

Systematic review.

Methods

We included qualitative and quantitative studies on nurses in advanced roles caring for people with diagnosed or suspected cognitive impairment and their relatives, assessing outcomes at patient, staff and organisational levels. Nurses' advanced role profiles ranged from nurse-led interventions up to Advanced Practice Nurses. We employed the Mixed Methods Appraisal Tool for critical appraisal and conducted a synthesis without meta-analysis using a content analysis approach.

Data Sources

MEDLINE, CINAHL, Cochrane Library, ALOIS, Web of Science and LIVIVO up to May 2024, along with forward and backward citation tracking.

Results

We included 48 studies that described 39 distinct interventions. The majority of these studies employed a quasi-experimental design. Most interventions involved Advanced Practice Nurses (n = 23) and focused on people at risk of or experiencing delirium (n = 22). Nurses in advanced roles predominantly engaged in tasks related to direct clinical practice, as well as coaching and guidance for patients, relatives and colleagues. Their responsibilities also included leadership, collaboration and consultation on a regular basis. Activities related to research and ethical decision-making were infrequently reported.

Conclusion

Many areas of responsibility of nurses in advanced roles align with the needs of hospitalised people with cognitive impairment. Nurses in advanced roles increasingly take on diverse activities across all competence domains of Advanced Practice Nursing, with a focus on coaching and guidance, as well as clinical practice, while leadership, collaboration, research and ethical decision-making become more prominent as their formal training advances.

Implications for the Profession and Patient Care

Our comprehensive description of advanced nursing roles in the care of people with cognitive impairment provides a foundation for developing and refining such roles in hospitals.

Reporting Method

We followed the PRISMA guideline and SWiM guideline for reporting.

Patient or Public Contribution

This study did not include patient or public involvement in its design, conduct or reporting.

Por: Zeng · L. · Li · R. · Li · S.-A. · Clarissa · S. · Agoritsas · T. · Chen · J. · Li · X. · Vandvik · P. O. · Brignardello-Petersen · R. · Li · X. · Zhang · L. · Guyatt · G.
Objectives

The aim of this study was to develop an educational video introducing an innovative panel survey approach to facilitate guideline panels in making inferences about patient values and preferences.

Design

A user testing of the educational video through one-on-one interviews and iterative refinement of the video through brainstorming meetings.

Setting

Interviews and brainstorming meetings were conducted through Zoom.

Participants

The participants of the interviews include guideline panellists who had used the panel survey approach, and guideline panellists who had not used the approach but would or would not participate in a panel survey soon. The participants of the brainstorming meetings were a steering committee with expertise in guideline methodology and qualitative research.

Primary and secondary outcome measures

The understandability and usefulness of the educational video.

Results

We interviewed 18 guideline panellists from eight different guideline panels, all of whom carefully reviewed the video. Most participants found the video useful in explaining the panel survey approach and its role in incorporating patient values and preferences. Participants suggested improvements, including clarifying key concepts and using plain language instead of technical terminology to make the content more accessible. The major change the steering committee decided to make through brainstorming meetings was to add clarification, refine the wording and replace some text with animation.

Conclusion

User testing resulted in an improved educational video that is more useful and understandable for guideline panellists. Wider implementation of this resource has the potential to enhance the incorporation of patient values and preferences in guideline recommendations, supporting more patient-centred decision-making.

Laparoscopic bariatric surgery versus any non-surgical intervention for adolescents or adults with obesity: protocol for a systematic review with meta-analysis and trial sequential analysis of randomised clinical trials

Por: Duun · O. · Dichman · M.-L. · Lindschou · J. · Scragg · J. · Petersen · J. J. · Nyvold Bojsen-Moller · K. · Jebb · S. A. · Gluud · C. · Dirksen · C.
Introduction

The number of people living with obesity is increasing rapidly worldwide, and the WHO estimates approximately 5 million deaths yearly from non-communicable diseases related to elevated body mass index (BMI). The most effective treatment for weight loss is bariatric surgery, but due to the associated risks and the need for lifelong care, this is not a viable treatment for every patient. With the advent of gut-hormone-based medications to treat obesity, the effectiveness of non-surgical treatment is approaching that of surgical interventions. We therefore aim to investigate the beneficial and harmful effects of laparoscopic bariatric surgery versus any non-surgical treatment.

Methods and analysis

We will conduct a systematic review with meta-analysis applying our eight-step procedure to assess thresholds for clinical significance and trial sequential analysis to mitigate the risk of random errors. To identify relevant trials, we will search for both published and unpublished trials, without any language restriction, in major medical databases (CENTRAL, MEDLINE, EMBASE, LILACS, SCI-EXPANDED and CPCI-S) and trial registries. The date range covered by the search is from database inception until final search date—within 3 months prior to submission of final results manuscript. Two review authors will independently screen references, extract data and perform risk-of-bias assessment using the Cochrane Risk of Bias Tool 2 and the Grading of Recommendations, Assessment, Development and Evaluations. We will include randomised clinical trials comparing laparoscopic surgery currently in use with any non-surgical comparator in adults or adolescents with BMI >30 kg/m2. Quasi-randomised studies or non-randomised studies will not be included. Our critical outcomes are all-cause mortality, serious adverse events and quality of life, and our important outcomes are major cardiovascular events, weight at follow-up, physical function and glycaemic control. In addition, we have two explorative outcomes: metabolic syndrome or Z-score and reported incident of alcohol abuse or other addictive disorder or self-inflicted harm.

Ethics and dissemination

This review will collect and perform secondary analysis of data from publicly available sources and ethical approval is therefore not required. The findings will be published in peer-reviewed journals and presented at relevant scientific conferences. We will strive to publish with open access. Awareness will be made through social media platforms. This review aims to help clinicians in identifying best practices in the wide-spanning field of obesity treatment.

Lives Transformed—The Experiences of Significant Others Supporting Patients With Severe Burn Injury: A Narrative Inquiry

ABSTRACT

Aim

To explore the experiences of significant others of patients with severe burn injury in the intensive care unit. Specifically, how severe burn injury impacted the significant other and their role within their loved one's life.

Design

This qualitative study employed a Narrative Inquiry approach.

Methods

Interviews were undertaken during 2021–2022 with 17 participants who were the significant others of a patient with severe burn injury in the Intensive Care Unit. Recruitment occurred in New South Wales, Australia, from two tertiary hospitals providing care for people with major burns. A narrative inquiry approach was utilised, capturing stories through semi-structured interviews.

Results

Significant others experienced necessary changes in their life in response to the catastrophe. These included advocating, being present and ensuring their loved one's needs were met, while often neglecting themselves. Significant others contemplated their future as a carer to their loved one with severe burn injury, and adjusting their own career, finances and lifestyle, often as a long-term measure. The shifting of their role to carer ultimately transformed and redefined their relationships and lives.

Conclusion

Significant others endure immense trauma when a loved one sustains a severe burn injury. They require support but prioritise the patient by virtue of their critical illness. The life of the significant other is changed as they take on the role of carer and provide support. It is, therefore, imperative that the support needs of significant others are recognised, understood and addressed to ensure their well-being while processing the trauma.

Implications for Practice

With increased understanding of the significant others' experiences, healthcare providers can adopt a consultative approach, where roles and boundaries can be clearly identified. Through this process, healthcare providers can strengthen rapport and provide targeted support for significant others, as they navigate this traumatic life-altering event.

The Impact of Assessing Patients' Sense of Security on Nurses' Intent to Report Safety Events: A Factorial Survey Experiment

ABSTRACT

Aims

To evaluate whether information about patients' poor sense of security in hypothetical vignette scenarios increases nurses' projected intent to report safety events.

Design

Quantitative, cross-sectional factorial survey vignette experiment administered online.

Methods

A convenience sample of 60 nurses from adult inpatient hospital units at a Midwest academic medical center participated in February 2025. Participants responded to demographic questions and eight factorial vignettes, each describing a patient-reported safety breach and incorporating four patient-related factors. Four vignettes included information that the patient had a poor sense of security, and four did not, presented in random order. Following each vignette, participants rated their level of concern about the patient's report, perceived harm to the patient, and likelihood of reporting the patient's concern. A linear mixed-effects modelling approach, accounting for clustering within participants, was used to estimate the effects of the sense of security information factor on nurses' responses.

Results

The sense of security information was associated with higher ratings of (a) degree of concern, (b) perceived harm to the patient, and (c) intent to report the patient's concern, after adjusting for vignette- and participant-level covariates. The vignette patient's perception of physical harm was positively associated with all three ratings. Nurses' greater hospital experience was associated with lower ratings across outcomes.

Conclusion

Obtaining information that the patient felt insecure was associated with heightened concern about the safety event, greater perceived harm, and increased intent to report the concern.

Implications for the Profession and/or Patient Care

Sense of security assessment may be a risk-agnostic, patient-centered intervention that nurses can routinely perform, regardless of the safety event circumstances.

Impact

Although a system of evidence-based practices within a safety culture is essential to hospital safety efforts, nurses' judgements of and responses to patient safety concerns play a critical role and should not be overlooked.

Reporting Method

STROBE guidelines.

Patient or Public Contribution

Obstacles and Aspirations for Improving Delivery of Cardiopulmonary Resuscitation to Wheelchair Users: A Qualitative Study

ABSTRACT

Aim

To describe obstacles and ideas for improvement for the delivery of cardiopulmonary resuscitation and basic life support to wheelchair users.

Design

A descriptive qualitative study underpinned by constructivism was conducted.

Methods

Semi structured interviews were completed with 26 participants from three cohorts: formal and informal carers, wheelchair users and healthcare professionals. Data were collected via online and in person interviews between February and June 2024. All participants were located in Australia, with the exception of one who was located in the United Kingdom. Data were analysed using thematic analysis.

Results

Two major themes were identified: (1) obstacles to providing cardiopulmonary resuscitation and basic life support to a wheelchair user and (2) aspirations for improving cardiopulmonary resuscitation and basic life support for wheelchair users.

Conclusion

Participants shared ideas for how to improve emergency care for wheelchair users, highlighting a need for further research, testing and development of an education intervention.

Implications for the Profession and/or Patient Care

Improving knowledge about providing emergency care to a wheelchair user could improve outcomes, save lives and reduce the life expectancy gap experienced by people with disability.

Impact

Approximately 2% of the global population use a wheelchair. Wheelchair use complicates the delivery of cardiopulmonary resuscitation and basic life support. There are currently no guidelines informing emergency care for wheelchair users available globally. Recognition of common symptoms of distress exhibited by wheelchair users, and options for the delivery of practical emergency care are required for wheelchair users.

Reporting Method

The paper adheres to the EQUATOR reporting guidelines utilising the SRQR checklist.

Patient or Public Contribution

Patients and the public were the driving force in recognising the gap in knowledge regarding the delivery of CPR to wheelchair users. Questions from patients and the public shaped the aims and methodological choices for this study.

Exploring the Impact of the Motherhood Penalty on Critical Care Nurses: A Hermeneutic Phenomenological Study

ABSTRACT

Aim

This study explores the lived experiences of critical care nurses who are also mothers, focusing on their challenges with breastfeeding and pumping at work.

Methods

Using interpretive phenomenology, grounded in Martin Heidegger's work, semi-structured interviews were conducted with critical care nurses (N = 54) who were also breastfeeding mothers in the United States in 2024. Data were transcribed verbatim and analysed using Patricia Benner's interpretation of the hermeneutic circle in nursing data analysis to identify the essence of lived experiences in breastfeeding as a critical care nurse mother.

Results

Four main themes emerged during the analysis. They are as follows: (1) The Impact of Workplace Environment on Breastfeeding Nurse Mothers and Their Children, (2) The Role of Organisational Support and Resources in Retaining Breastfeeding Nurse Mothers in Critical Care, (3) Team Dynamics and Career Implications of Breastfeeding for Nurse Mothers in Critical Care and (4) Organisational and Systemic Approaches to Supporting Breastfeeding Nurse Mothers in Critical Care.

Conclusions

The findings highlight critical gaps in workplace policies and support systems for breastfeeding nurses. Addressing these inequities through the provision of adequate lactation facilities, flexible pumping schedules and a supportive workplace culture is essential to reducing stress and enabling nurse mothers to continue breastfeeding successfully. This study underscores the need for systemic reforms to support breastfeeding in the nursing profession.

Turnover and Intention to Leave Among Belgian Healthcare Workers After COVID‐19: A Two‐Year Longitudinal Cohort Study

ABSTRACT

Aim

To investigate the association between healthcare workers' demographic and work-environment variables during the COVID-19 pandemic and their turnover intentions or actual turnover after two years.

Design

Two-step longitudinal cohort study.

Methods

A nationwide longitudinal cohort study was conducted using a convenience sample of Belgian HCWs who participated in online surveys at two time points: November 24th, 2021, to March 15th, 2022 (Period 1), and November 16th, 2023, to December 12th, 2023 (Period 2).

Results

Out of 2149 participants in the first survey, 700 responded in the second. During the pandemic, 31.3% intended to leave the profession. In Period 2, 52.3% of those reaffirmed their intention or had left (6.5%). Work autonomy, resilience, and perceived patient harm predicted turnover intention. Pandemic-related work pressure was the primary reason for leaving.

Conclusion

Promoting healthcare workers' autonomy and resilience is crucial for mitigating turnover. HCWs who experience patient harm during a pandemic will have a higher risk for turnover. Knowing this, healthcare managers and policymakers should develop strategies to prepare for future health crises.

Implications for the Profession and Patient Care

Enhancing work autonomy and resilience among healthcare workers can improve retention and job satisfaction, ultimately leading to better patient care and a more stable healthcare workforce.

Impact

Problem Addressed: The study addresses the high turnover intentions among healthcare workers during and after the COVID-19 pandemic.

Main Findings: Work autonomy, resilience, and perceived patient harm due to workload are significant predictors of turnover intentions.

Impact: The research impacts healthcare managers and policymakers by providing insights into factors that can improve healthcare workers' retention and job satisfaction.

Reporting Method

This study adhered to the STROBE guidelines for reporting observational studies.
