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.

Biphasic sleep in shift workers and its related outcomes: a scoping review protocol

Por: Moen · L. V. · Lie · J.-A. S. · Jorgensen · I. L. · Frojd · L. · Pallesen · S. · Matre · D.
Introduction

Shift work is associated with disrupted sleep, circadian misalignment and increased risks of adverse health, performance and safety outcomes. Although recommendations for shift workers typically focus on obtaining one long sleep period, many shift workers divide sleep into two episodes, referred to as biphasic sleep. Biphasic sleep may help mitigate sleep loss-related impairments, yet its prevalence, characteristics and potential benefits for shift working populations remain unclear. Existing reviews have examined sleep duration, mental health, or the consequences of shift work broadly, but none have specifically mapped evidence comparing biphasic and monophasic sleep between shifts. This scoping review will identify and summarise the available literature on biphasic sleep among adult shift workers. In addition, we will describe the outcomes and subsequently highlight any possible gaps to inform future research.

Methods and analysis

This review will follow the Joanna Briggs Institute methodology for scoping reviews and be reported in accordance with the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews guidelines. Biphasic sleep is defined as two distinct sleep episodes within a 24-hour period between work shifts, including two similarly timed sleep periods or one longer sleep combined with a shorter nap. A comprehensive search will be conducted in April 2026 in MEDLINE, Embase, PsycINFO, Web of Science and CENTRAL using controlled vocabulary (eg, Medical Subject Headings) and free-text terms related to shift work and split sleep. Peer-reviewed primary research examining biphasic sleep among adult shift workers will be included, and studies focusing solely on naps during work hours will be excluded. Two reviewers will independently screen titles/abstracts and full texts, with discrepancies resolved through discussion or by consulting a third reviewer. Data will be extracted using a standardised template including study characteristics, sleep parameters and reported outcomes. Results will be summarised descriptively and presented in tables and evidence maps. No statistical synthesis will be performed.

Ethics and dissemination

This scoping review will synthesise data from articles published in peer-reviewed journals. As no primary data will be collected and no human participants will be involved, the review is exempted from formal ethical approval. Findings will be disseminated in terms of a peer-reviewed publication and will inform future systematic reviews on sleep strategies among shift workers.

Societal consequences of IPS implementation in Norway 2012-2019: study protocol for the IPSRON effectiveness study

Por: Mykletun · A. · Aars · N. A. · Lorentzen · T. · Rinaldi · M. · Sandtorv · E. · McDaid · D. · Moe · C. F. · Park · A.-L. · Killackey · E. · Brinchmann · B.
Introduction

Individuals experiencing moderate to severe mental illness have low rates of workforce inclusion, with a consequence of high welfare dependency, affecting both societal costs and health. Individual Placement and Support (IPS) is an approach to supported employment where the goal is to help people obtain jobs on the open rather than sheltered labour markets. Despite multiple randomised controlled trials (RCTs) indicating that the IPS model enables employment better than treatment as usual, with widespread adoption in some jurisdictions, the broader impacts of this large-scale implementation on mental health, quality of life and social functioning remain unknown.

Methods and analysis

Between 2012 and 2019, Norway introduced IPS through both local and national government projects. This study assesses the social and economic benefits of the implementation of IPS using Norwegian registry data, focusing on 18–45-year-old people receiving specialist mental healthcare, and who did not have steady employment at treatment start. Instead of assessing IPS efficacy in an RCT design, we use a naturalistic study design, evaluating IPS effectiveness by comparing aggregate population-level outcomes over time between areas where IPS was not available.

In work package (WP) 1, we mapped the availability and implementation of IPS across Norway. This involved analysing information on funding, resource and capacity levels to understand how IPS had been rolled out across the country. While completed, we include a description of WP1 here, as it informs WP2 and WP3. WP2 is an effectiveness evaluation investigating the population-level outcomes of implementing IPS, focusing on health, mortality, quality of life and social functioning. Finally, in WP3, we assess the financial implications of implementing IPS from a public purse perspective, synthesising data on resource use and costs of implementation with data from WP2.

Overall, we will examine the societal effects of IPS implementation on employment, welfare dependency, mental healthcare use, emergency care visits, self-harm and suicide, general mortality, crime and victimisation. Emphasis will be on long-term outcomes, and we will model the economic consequences of IPS. This study aims to inform policy making and strategies for implementing IPS at scale.

Ethics and dissemination

This is an effectiveness study using registry data. The Regional Committee for Medical Research Ethics Northern Norway, REK North has approved the use of registry data without informed consent for this project (approval number 134553).

The findings will be disseminated both in academic peer-reviewed journals, directly to informants in WP1, to the public through media and the project website, and at relevant conferences and seminars for specific relevant target groups.

Comparison of in-hospital outcomes and processes of care by patient and physician sex: a single-centre retrospective cohort study

Por: Moeschler · S. · Yi · S. · Clair · C. · Vollenweider · P. · Marques-Vidal · P. · Mean · M.
Objective

Prior research, mostly from North America, suggests improved clinical outcomes for female patients treated by female physicians. Whether these findings apply in European healthcare systems and how underlying processes of care vary by sex remains unclear. This study aimed to assess whether in-hospital outcomes and processes of care differ by patient sex, physician sex or their interaction, in a European setting.

Design

Retrospective cohort study.

Setting

General internal medicine division of a Swiss tertiary teaching hospital.

Participants

Adult inpatients (≥18 years) hospitalised between 2014 and 2024 and their primarily responsible physicians, classified by administrative sex (male vs female). The cohort included 20 094 hospitalisations (44.6% female patients) and 216 physicians (48.1% female).

Outcome measures

Outcomes included in-hospital mortality, 30-day mortality and 30-day readmission, as well as processes of care (resource use, advance care planning and cardiovascular low-value care). Multilevel mixed-effects regression models adjusted for patient and physician characteristics.

Results

Female patients had lower in-hospital mortality (OR 0.72, 95% CI 0.59 to 0.89) and 30-day mortality (OR 0.75, 95% CI 0.65 to 0.87), lower hospitalisation costs (–4.26%, 95% CI –6.08% to –2.41%), fewer diagnostic and therapeutic procedures (–6.44%, 95% CI –9.76% to –3.01%), fewer blood tests (–8.95%, 95% CI –12.98% to –4.73%) and were less likely to have resuscitation orders (OR 0.64, 95% CI 0.58 to 0.71) or intensive care unit transfer orders (OR 0.64, 95% CI 0.55 to 0.73). They were, however, more likely to receive non-indicated antihypertensive treatment (OR 1.86, 95% CI 1.38 to 2.51). No significant differences were observed by physician sex or patient–physician sex interaction.

Conclusions

In a European tertiary teaching hospital with universal healthcare coverage, in-hospital outcomes and processes of care did not differ by physician sex or patient–physician sex interaction. Nevertheless, disparities by patient sex persisted, underscoring the need for sex-disaggregated quality monitoring and sex-sensitive medical training.

Relationship Between Weight Loss and Problems With Oral Intake in Institutionalised Older Adults: A Japanese Multi‐Institutional 1‐Year Follow‐Up Study

ABSTRACT

Aim

To examine the relationship between weight loss and problems with oral intake in institutionalised older adults.

Design

A 1-year longitudinal observational study.

Methods

Data were obtained from a prospective study conducted in three nursing homes and two long-term care facilities in Japan. Participants' problems with oral intake were assessed using items published in 2021 by the Japanese Ministry of Health, Labour and Welfare. Baseline and follow-up factors were compared between individuals who experienced a weight loss of 5% or more and those who did not. Separate multivariable logistic regression models were constructed for each oral intake assessment item to examine its independent association with weight loss of 5% or more, accounting for transitions in each item between baseline and the 1-year follow-up.

Results

In total, 172 institutionalised older adults were included in the analysis. Among them, 57 (33.1%) participants experienced a weight decrease of 5% or more. The emergence of somnolence or clouding of consciousness during meals at the 1-year follow-up in participants without these signs at baseline was independently associated with a weight loss of 5% or more, after adjustment for baseline characteristics.

Conclusion

Recognising signs of somnolence or clouding of consciousness during meals may be useful for the early detection and prevention of weight loss in institutionalised older adults.

Implications for the Profession and/or Patient Care

Early detection of individuals at risk is essential to prevent significant weight loss and its associated adverse outcomes. Recognising somnolence or clouding of consciousness during meals may enable earlier detection and intervention to prevent weight loss and improve the quality of care for older adults.

Exploring differences in health-related benefit status in the year before, during and after specialist rehabilitation: a Norwegian case-control study

Por: Skinnes · M. N. · Uhlig · T. · Johansen · T. · Morvik · H. K. · Farsund · N. · Fossen · J. · Skardal · R. F. · Tollin · G. · Degirmenci · A. E. T. · Habberstad · A. · Sexton · J. · Kollerud · R. · Kjeken · I. · RehabNytte Consortium · Wilkie · R. · Moe · R. H.
Objectives

To explore differences in health-related benefit status over 3 years, focusing on patterns of sick leave, work assessment allowance and disability benefits, between people who underwent rehabilitation and a matched control group.

Design

Prospective longitudinal multicentre cohort study using registry data over three consecutive years.

Setting

Secondary specialist rehabilitation services at 17 institutions across Norway.

Participants

Patients (n=2710), 42% with rheumatic and musculoskeletal diseases, aged 18–65 years referred for multidisciplinary rehabilitation at one of the participating institutions. They were propensity score matched with 37 760 controls from the national sick leave registry, based on sociodemographic factors and health-related benefit status.

Intervention

Multidisciplinary rehabilitation programmes, commonly lasting 3 weeks (range: 1 week to 6 months), tailored to individual needs.

Primary outcome measures

Days on health-related benefits (sick leave, work assessment allowance (WAA) and disability benefits) were quantified as lost workdays per month. Differences between groups were analysed using Generalised Estimating Equations across three consecutive years: the year before rehabilitation, the rehabilitation year and the year after rehabilitation.

Results

The rehabilitation group had more days on health-related benefits per month than controls throughout the observation period. During the rehabilitation year, they had on average 1.7 more days on sick leave (95 % CI 1.3 to 1.9), 2.3 more WAA days (95% CI 1.9 to 2.7) and 0.2 more days on disability benefits (95% CI 0.1 to 0.3). In the year after rehabilitation, they had 0.6 fewer days on sick leave (95% CI –0.8 to –0.3), but 3.7 more days on WAA (95% CI 3.1 to 4.2) and 0.6 more days on disability benefits (95% CI 0.4 to 0.8). Patterns were similar for the subgroup with rheumatic and musculoskeletal diseases.

Conclusions

People undergoing rehabilitation had more days on health-related benefits and a greater increase in long-term benefits, even after matching, indicating a higher disease and support burden than controls. Tailoring interventions and health-related benefits is an essential aspect of rehabilitation for people with complex work participation needs. Future research should include longer observation periods to explore long-term outcomes of rehabilitation.

Womens experiences of wound dehiscence of a second-degree perineal tear and choice of treatment in Denmark: a qualitative interview study

Por: Moestrup · L. V. · Jangö · H. · Bergholt · T. · Klarskov · N. · Hogh · S. · Hegaard · H. K.
Objective

This study aimed to describe women’s experiences of perineal wound dehiscence of a second-degree perineal tear and choice of resuturing or conservative treatment in the first two months after birth.

Design

A qualitative descriptive study using individual semistructured interviews was conducted. Data were analysed using Braun and Clarke’s reflexive thematic analysis approach to explore women’s experiences and perspectives on dehisced perineal wounds of a second-degree perineal tear. Interviews were audio-recorded, transcribed verbatim and analysed concurrently with data collection.

Setting

Perineal clinics at the Department of Obstetrics and Gynaecology at two large University Hospitals in Copenhagen, Denmark.

Participants

17 women with dehisced perineal wound of a second-degree perineal tear.

Results

Three main themes were identified: (1) The unforeseen troubles: for the women with perineal wound dehiscence, the pain intensified immensely after the birth. It was an unexpected complication, and it affected the women negatively in various ways. (2) The emotional turmoil: it was a crisis for the women that their lower bodies were not intact. They were terrified, and they wondered if they had themselves to blame. Most women emphasised that choosing between resuturing or conservative treatment was a difficult and lonely decision. (3) Living with changes: regardless of treatment approach, women in both groups reported gradually managing their complicated healing and pain, but were concerned about their genitals and future births.

Conclusions

The findings indicate that wound dehiscence was related to a painful postpartum period and an altered body image, and that the women generally found choosing between resuturing or conservative treatment difficult.

Mitigating chronic respiratory disease through the lens of multimorbidity: the MARES mixed-methods study protocol

Introduction

Chronic respiratory diseases (CRDs), such as asthma and chronic obstructive pulmonary disease (COPD), are among the leading non-communicable diseases (NCDs) worldwide. However, diagnosing CRDs in low-income and middle-income countries (LMICs) remains challenging due to limited access to spirometry and trained professionals. Aggravating the burden, CRDs often coexist with other NCDs, increasing healthcare costs, reducing quality of life and elevating mortality. These challenges highlight the need for simple case-finding approaches for CRDs, such as the COPD in Low-Income and Middle-Income Countries Assessment (COLA-6) questionnaire, to support prompt identification and appropriate care within NCD services in LMICs.

Objective

To evaluate the discriminative accuracy, feasibility and implementation of the COLA-6 questionnaire in identifying and managing CRDs in Brazilian Primary Healthcare (PHC) services for NCDs.

Methods and analysis

The Multimorbidity Approach for REspiratory Solutions (MARES) study consists of three work packages to be conducted in PHC services in São Carlos/SP and São Paulo/SP, Brazil.

MARES-1: A cross-sectional observational study enrolling 859 individuals with at least one NCD receiving care in PHC. The COLA-6 questionnaire will be administered by the research team and compared with quality-assured spirometry. The Chronic Airways Assessment Test (CAAT), Asthma Control Questionnaire (ACQ-7) and fractional exhaled nitric oxide (FeNO) will also be assessed. The diagnostic performance of COLA-6 for identifying CRDs—including COPD, asthma, preserved ratio impaired spirometry, restriction and overlaps—will be assessed using area under receiver operating characteristic curves and 95% CIs.

MARES-2: A cross-sectional observational study enrolling 20 healthcare professionals (physicians, physiotherapists, community health agents and nurses) from five PHC services. These professionals will apply the COLA-6 during routine NCD care to a total sample of 1000 patients. Qualitative interviews will be conducted to explore barriers and facilitators to the implementation of COLA-6, using deductive thematic analysis.

MARES-3: A longitudinal, prospective observational study in which patients from MARES-1 and MARES-2 will be reassessed at 6-month follow-up. A total sample of 473 participants with abnormal spirometry, a diagnosis of CRD or high risk for CRDs is expected. Participants will undergo spirometry, and a subset will be interviewed to explore their healthcare experiences through qualitative thematic analysis. Access to diagnostic and treatment services in Brazil will be assessed. Changes in spirometry values, FeNO, CAAT and ACQ-7 scores from baseline to 6 months in patients from MARES-1 will be analysed.

Ethics and dissemination

This study has been approved by the Ethics Committees of Federal University of São Carlos and University of Santo Amaro (UNISA). Ethical approval was also granted by the University College London. Results will be disseminated through peer-reviewed medical journals and presentations at international conferences. Results will improve identification of CRDs, addressing a significant gap in current PHC settings.

Adherence in Patients With Heart Failure—Relationships to Symptom Burden and Hospitalisation Frequency: A Cross Sectional Survey Study

ABSTRACT

Aims

To investigate adherence and non-adherence to treatment regimens among heart failure patients and to explore relationships with symptom burden and hospitalisation frequency.

Design

The research employed a cross-sectional survey study design.

Methods

The online survey “Living with heart failure”, was conducted among patients attending the Cardiac outpatient clinic at a Swedish University Hospital over the course of a calendar year. Data analysis employed descriptive statistics using the statistical processing program SPSS.

Results

The survey was made accessible to 1395 respondents; 479 individuals participated. The response rate was 34.3%. 73.6% were classified as non-adherent and 26.4% as adherent. Among the non-adherent, a statistically significantly higher symptom burden was observed. Lower hospitalisation frequency was associated with higher adherence and lower symptom burden. Frequent hospitalisations correlated with lower adherence and more severe symptoms.

Conclusion/Implications

This study underscores the prevalence of non-adherence in the heart failure population and emphasises the importance of addressing this issue.

Impact

Non-adherence to treatment regimens remains a global challenge, historically underestimated and challenging to quantify. Non-adherence to medical treatment in the heart failure population is about 50%; non-adherence from a wider perspective implicates a gap of knowledge. The principal discoveries from this study underscore the extensive non-adherence and its exacerbating effects on symptom burden and hospitalisation. The primary significance of this research will manifest among caregivers in multidisciplinary teams providing support to the heart failure population.

Reporting Method

The Equator Guidelines Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) were adhered to.

Pedagogical Strategies for Teaching Conceptual Models and Nursing Theories in Undergraduate Students: A Scoping Review

ABSTRACT

Background

Teaching nursing theories is essential to structure and guide clinical practice, yet their integration into initial training courses remains a challenge.

Aim

To map the educational practices used to teach nursing theories and conceptual models in initial nursing training programmes.

Design

A scoping review.

Methods

Is review was conducted following the guidelines of the Joanna Briggs Institute and the PRISMA-ScR. A comprehensive search of five databases and in the grey literature was conducted to find studies from the inception of the databases to January 2024. A total of 32 articles meeting the inclusion criteria were selected for analysis.

Results

The findings reveal a wide variety of educational techniques, ranging from traditional lectures to innovative Methods such as simulation and virtual games. The analysis also shows that these educational practices cover a broad Spectrum of theories, from well-established theories that have stood the test of time, such as watson's, to more recent Theories like the fundamentals of care.

Conclusion

While integrating nursing theories into initial training programmes is crucial, further research is needed to assess the effectiveness of the pedagogical strategies used to teach them. The mapping of educational practices carried out in this review serves as a valuable resource for educators, providing a structured basis to diversify and enrich the teaching of nursing theories.

Implications for Practice

This scoping review explores for the first time the range of pedagogical practices used in the teaching of nursing theories on an international scale. It provides a valuable resource for educators, allowing them to enrich their pedagogical approach. It offers a structured overview of the various possible methods, thus facilitating the adaptation of teaching strategies to different contexts. This methodological diversity can also serve as a source of inspiration for developing new concepts for teaching disciplinary fundamentals. The renewed interest in teaching disciplinary fundamentals underscores the relevance of this review in the current context.

Impact

Through this mapping of pedagogical strategies, this scoping review contributes to improving the quality of teaching nursing disciplinary fundamentals internationally. The results provide a foundation for developing specific courses on nursing conceptual models and theories, offering educators various possibilities to enrich their teaching methods while adapting to local contexts and student needs.

Redirecting patients from the pediatric emergency department to community locations for care: A qualitative study of healthcare professional and leader perspectives

by Erica Qureshi, Quynh Doan, Jessica Moe, Steven P. Miller, Garth Meckler, Brett Burstein, Jehannine (J9) Austin

Objectives

Emergency department (ED) to community (ED2C) programs, which redirect patients from the pediatric ED to community healthcare professionals represent a promising strategy to reduce the impact of non-urgent visits on the pediatric ED. Given an ED2C program’s potential impact on various care professionals, we completed a qualitative study to explore key informants’ attitudes and perceptions of pediatric ED2C programs.

Methods

We conducted one-on-one semi-structured interviews with key informants in British Columbia, Canada. Participants included: pediatric ED staff – triage nurses and physicians; community professionals – pediatricians and family physicians; and health system leaders responsible for pediatric and emergency care in British Columbia. Interviews were recorded, transcribed verbatim, de-identified, and analyzed using reflexive thematic analysis within an interpretive description framework. A visual model was developed to depict key themes in attitudes and perceptions towards pediatric ED2C programs.

Results

We interviewed 24 participants: 6 community professionals, 11 pediatric ED professionals, and 7 healthcare leaders. Participants viewed the ED2C program as a valuable solution to address pediatric system strain provided that systemic barriers are addressed, and both emergency and community settings are equipped with adequate training and resources. Participants emphasized the need for clear guidelines on eligibility and operations to build confidence and enhance program effectiveness.

Conclusions

Our findings suggest there is support for ED2C programs as a means to reduce the impact of non-urgent pediatric ED visits and strengthen community-based care. Successful implementation will require coordinated planning, resource investment, and clear operational frameworks.

MiR-125b-5p and miR-100-5p as Biomarkers and therapeutic targets for the prevention of particulate matter-induced non-smoker lung cancer

by Moe Thi Thi Han, Tay Zar Myo Oo, Busayamas Chewaskulyong, Sakorn Pornprasert, Kanyamas Choocheep, Khanittha Punturee, Warunee Kumsaiyai, Yupanun Wuttiin, Sawitree Chiampanichayakul, Ratchada Cressey

Non-smoking-related lung cancer is increasingly associated with environmental factors such as particulate matter (PM) exposure. Using deep small RNA sequencing, we identified distinct miRNA expression patterns in lung cancer patients compared to non-cancer controls, stratified by smoking status. Notably, hsa-miR-125b-5p and hsa-miR-100-5p were significantly downregulated in non-smoking lung cancer patients. Pathway enrichment analysis revealed smoking amplifies pathways related to glycan biosynthesis, signal transduction, and transcriptional regulation, while non-smoking lung cancer is characterized by immune dysfunction and metabolic alterations, including oxidative phosphorylation and natural killer cell cytotoxicity. Validation in a larger cohort using quantitative RT-PCR confirmed the suppression of miR-125b-5p and miR-100-5p in non-smoking lung cancer patients. Additionally, miR-203a and miR-199a-3p were identified as potential biomarkers for lung cancer, independent of smoking status. Chronic PM exposure in primary bronchial/tracheal epithelial cells initially elevated miR-125b-5p and miR-100-5p expression, but prolonged exposure suppressed these miRNAs while increasing their target genes, TXNRD1 and HOXA1, suggesting stress-induced dysregulation. Functional studies using miRNA mimics demonstrated that miR-125b-5p and miR-100-5p suppress PM-induced cancer cell mobility and colony formation, with miR-125b-5p exhibiting broader effects. These findings underscore the critical roles of miR-125b-5p and miR-100-5p in PM-associated lung cancer progression and their potential as biomarkers and therapeutic targets. This study highlights distinct mechanisms of lung carcinogenesis in smokers and non-smokers, providing a foundation for targeted interventions in PM-associated lung cancer.

Competencies Required for Hospital‐Based Wound, Ostomy, and Continence Nurses to Provide PI Care in Home Care in Japan: A Mixed‐Methods Study

ABSTRACT

Aim

To identify the competencies required for hospital-based WOC nurses to provide direct pressure injury (PI) care in home care settings in Japan.

Design

Mixed methods convergent design.

Methods

The qualitative strand used a descriptive design to explore competencies for overcoming barriers faced by hospital-based WOC nurses when providing PI care at home. The quantitative strand used a cross-sectional design to assess competencies in organising the hospital PI management system.

Results

Six competencies were identified: (1) Establish relationships with home healthcare professionals; (2) Promote hospital-based WOC nurse's expertise to home healthcare professionals; (3) Collaborate with the regional medical liaison office in WOC nurse's hospital; (4) Involve hospital administrators in home PI management; (5) Utilise social media/Information and Communication Technology for patient or home-visiting nurse communication; and (6) Utilise public or academic support projects to facilitate home-based activities. The median scoring rate for each medical staff domain on the revised Collaboration Competency Scale for WOC Nurses ranged from 80% to 91%.

Conclusion

The results of this study can serve as a practical resource to help WOC nurses expand their activities into home-care settings.

Implications for the Profession

Their ability to coordinate with staff and manage PI care within hospitals supports active engagement in home care, improving continuity and quality.

Impact

This study addressed the issue that many hospital-based WOC nurses cannot visit patients at home. The competencies identified may enable these nurses to expand their role into home care.

Reporting Method

This study followed EQUATOR guidelines, with the STROBE Statement applied to the quantitative part and the COREQ checklist to the qualitative part.

Patients or the public were not involved in the study's design, conduct, or reporting.

Patient-related and organisational characteristics associated with late cancellations and non-attendance in diabetes outpatient care: a cross-sectional study

Por: Singstad · T. · Holmen · H. · Smastuen · M. C. · Nermoen · I. · Ribu · L. · Torbjornsen · A.
Objective

We aimed to explore the patient-related and organisational characteristics associated with late cancellations and non-attendance in diabetes outpatient care and present our findings organised as a risk matrix based on these characteristics.

Design

A cross-sectional study.

Setting

Our study was conducted at an endocrinology outpatient clinic based on data extracted between January and December 2019 from electronic medical records.

Participants

Adult patients with type 1 diabetes with late cancellations or non-attendance. We compared our sample with national data for comparison and to assess representativeness.

Primary and secondary outcome measures

Main outcome was late cancellations or non-attendance, while secondary outcomes included type of cancellations and reason for cancellation.

Results

In total, 541 patients had late cancellations or non-attendance across 5040 diabetes consultations. These patients had a mean age of 43 years, 57.9% were men and half (n=301, 55%) were employed. The mean diabetes duration was 18 years, and the mean HbA1c level was elevated at 72 mmol/L. The outpatient clinic had a higher number of consultations, but the patient characteristics were comparable to the national average. Half of the patients (n=258, 52.3%) had late cancellations ahead of their consultations. Most cancellations occurred during the winter, mainly due to illness being the most frequent reason. Unemployed men with poorly regulated diabetes were more likely not to attend compared with employed females.

Conclusions

Characteristics such as being male, unemployed and having elevated HbA1c levels were significantly associated with non-attendance. Our findings contribute to understanding the reasons for at-risk patients missing consultations.

Neurofunctional phenotyping to investigate the role of the orexin system at the intersection of opioid use disorder and insomnia: a protocol for a randomised, placebo-controlled clinical trial of lemborexant in patients with insomnia receiving buprenorphi

Por: Marcus · M. M. · Alattar · M. · Chen · S. · Sabo · R. · Pignatello · T. · Ruddley · J. · Green · A. R. · Swan · K. · Keyser-Marcus · L. · Moeller · F. G. · Martin · C. E.
Introduction

Insomnia is a common complaint among patients with opioid use disorder (OUD) maintained on buprenorphine (BUP). However, people with OUD have historically been excluded from insomnia clinical trials, leaving clinicians without evidence-based treatment options for this patient population. Lemborexant, the Food and Drug Administration (FDA)-approved dual orexin receptor antagonist for the treatment of insomnia, was recently shown to be safe and tolerable among a sample of patients with insomnia who were maintained on BUP. We hypothesise that pharmacologically antagonising the orexin system with lemborexant may improve insomnia symptoms in individuals with OUD and also enhance BUP treatment benefits by improving performance in neurofunctional domains identified in the National Institute on Drug Abuse Phenotyping Assessment Battery.

Methods and analysis

Participants with insomnia and OUD who have been stabilised on BUP for at least 4 weeks will be randomly assigned to receive either lemborexant (n=50) or placebo (n=50) for 8 weeks. Participants will complete assessments at baseline, during the 8-week intervention, postintervention and at a 2-week follow-up. Primary outcomes are insomnia severity and impulsivity. Secondary measures include objective sleep metrics (total sleep time, sleep efficiency, sleep onset latency and wake after sleep onset) and performance in the neurofunctional domains of negative emotionality and metacognition.

Ethics and dissemination

The study was approved by the Virginia Commonwealth University Institutional Review Board in April 2025 (protocol number HM20031777). Data collection began in May 2025 and is expected to be completed by May 2029. The trial is conducted under FDA IND no. 154797 (FGM). The dissemination plan for the trial includes presentations at local and national conferences, submission of primary and secondary outcome manuscripts for publication in peer-reviewed journals and circulation of findings to popular media outlets, as available. Results will also be shared with interested participants and clinical collaborators upon completion of the trial.

Tensive Adaption: A Grounded Theory on the Process of Nurses' Dealing With Workplace Violence

ABSTRACT

Aim

To explore the process of how nurses experience and deal with workplace violence based on nurses' perceptions and experiences in Iran.

Methods

An exploratory qualitative study was conducted using grounded theory approach. Participants included 17 nurses working in 4 hospitals in 2 urban areas in Iran with at least 1 year of clinical experience in emergency departments and intensive care units. Data were collected through in-depth, semi-structured individual interviews conducted between August 2024 and March 2025. The constant comparative analysis approach was used for data analysis. This research method was carried out in five stages: open coding to identify concepts; development of concepts in terms of their characteristics and dimensions; contextual analysis; integration of the process to data analysis; and final category integration.

Findings

The main concern of participants in dealing with workplace violence was a ‘multidimensional security threat’. ‘Perpetrator response to nursing care’ (at the individual level) and ‘organisational inefficiency’ (at the organisational level) provided the context for this threat. A general theme entitled ‘tensive adaptation’ was the core category in this research and included four main categories: ‘tolerant reactions’, ‘seeking help’, ‘passive reactions’ and ‘hostile reactions’. ‘Organisational damage’, ‘nurse damage’ and ‘patient damage’ were the outcomes.

Conclusion

The theoretical model of ‘tensive adaptation’ provides a new perspective on ‘what’ and ‘how’ nurses experience and manage workplace violence. Effective strategies for managing violence such as effective communication, empathy, providing appropriate care, anger management, self-care, effective teamwork and requesting support can be considered by nursing administrators and incorporated into training programmes for nurses and nursing students. The adverse consequences of nurses' exposure to workplace violence should receive greater attention, as the entire healthcare system is affected by this exposure.

Implications for the Profession and/or Patient Care

Workplace violence leads to physical and psychological problems, reduced job satisfaction, diminished performance, negative effects on personal and family life and decreased quality of patient care. The main concern of participants in dealing with workplace violence was ‘multidimensional security threat’. This concept includes three characteristics: ‘psychological health threats’, ‘physical health threats’ and ‘professional position threat’. ‘Perpetrator response to nursing care’ (individual level) and ‘organisational inefficiency’ (organisational level) served as contextual conditions that expose nurses to workplace violence. In ‘tensive adaptation’, nurses attempt to respond to workplace violence through strategies such as ‘tolerant reactions’, ‘seeking help’, ‘passive reactions’ and ‘hostile reactions’. ‘Organisational damage’, ‘nurse damage’ and ‘patient damage’ are the consequences of nurses' exposure to workplace violence.

Objective

To systematically review the evidence on the association between non-standard working time arrangements (such as night work or shift work) and the occurrence of safety incidents.

Design

Systematic review conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and using a structured narrative approach and the Synthesis Without Meta-analysis framework to evaluate and summarise findings.

Data sources

MEDLINE, Embase, PsycINFO, Web of Science and ProQuest Health and Safety Science Abstracts were searched through February 2024.

Eligibility criteria for selecting studies

We included peer-reviewed English-language studies of paid workers (18–70 years) that examined the association between non-standard working time arrangements and safety incidents (accidents, near-accidents, safety incidents or injuries), excluding cross-sectional designs and studies on unpaid workers, athletes or military personnel.

Data extraction and synthesis

Two reviewers independently extracted data and assessed risk of bias using standardised forms, extracting study characteristics (author, year, country, sector and population), working time arrangements and exposure assessment, outcomes and their assessment, and reported risk estimates. We conducted a narrative synthesis, classifying studies into three exposure contrasts (shift worker versus non-shift worker, time-of-day and shift intensity), and summarised risk estimates using forest plots without calculating pooled effects.

Results

A total of 13 569 records were screened, and 24 studies met the inclusion criteria. The results indicated that shift workers generally had an elevated safety incident risk compared with non-shift workers (risk estimates ranged from 1.11 to 5.33). Most of the included studies found an increased risk of safety incidents during or after night shifts. Accumulated exposure to evening or night shifts increased the risk of safety incidents during the following 7 days. However, bias and heterogeneity across studies in design, populations and outcome measures resulted in an overall low to very low certainty of the evidence.

Conclusions

Non-standard working time arrangements, including night and evening shifts, appear to increase the risk of occupational safety incidents. Despite the low certainty of evidence, the findings highlight a potential area for preventive measures in work scheduling. Future longitudinal studies using individual data on daily working hours are needed.

Introduction

Asthma is a leading cause of morbidity and healthcare use among children. Risk factors of childhood asthma include atopic predisposition and severe wheezing episodes caused by rhinovirus infection in early life. In children with first-time rhinovirus-induced wheezing, we aim to study the response of a short corticosteroid treatment to prevent recurrent wheezing and asthma.

Method and analysis

This is a double-blind, randomised, placebo-controlled, phase IV, international multicentre trial involving eight sites in Norway, Sweden and Finland. Two hundred and eighty 3–23 months old steroid-naïve children are randomised 1:1 to receive oral dexamethasone (0.3 mg/kg/day) versus placebo in 3 days for their first wheezing episode and rhinovirus infection. Rhinovirus is diagnosed with multiplex PCR. The two co-primary outcomes are time to next physician-confirmed wheezing episode, and time to asthma, within 24 months from inclusion. Asthma is defined as fulfilment of the 2007 National Asthma Education and Prevention Program—criteria for initiating asthma controller medication in children aged 0–4 years. Primary interaction analyses are age, gender, atopic predisposition, risk genotypes and viral co-detection. The optimal cut-off on the rhinovirus genome load used to define a true rhinovirus infection will be assessed by exploring interactions between rhinovirus genomic loads and study drug on the co-primary outcomes. Secondary outcomes are number of wheezing episodes, duration and severity of each wheezing episode, bronchial hyperreactivity, quality of life and safety (height/weight development) at 24 months from inclusion.

Ethics and dissemination

Rhinovirus positive children with acute wheezing fulfilling inclusion and exclusion criteria are enrolled after informed consent from both caregivers. This trial has received ethical approval from all sites. Results will be submitted to Competent Authorities and disseminated via peer-reviewed publications and conferences within paediatrics and other relevant fields. If proven effective, findings may be implemented directly into paediatric clinical guidelines.
