A genomic locus uniquely encoded by blueberry-infecting <i>Xylella fastidiosa</i> strains affects motility and biofilm formation in vitro, and virulence in planta

by Navdeep Kaur, Marcus V. Merfa, Alexandra K. Kahn, Rodrigo P. P. Almeida, Leonardo De La Fuente

Xylella fastidiosa (Xf) is an insect-transmitted, xylem-limited bacterial plant pathogen that infects hundreds of plant species. This pathogen causes bacterial leaf scorch in southern highbush blueberry (Vaccinium corymbosum interspecific hybrids) in the southeastern United States, a disease that has not yet been reported elsewhere. Previously, a comparative genomic analysis of Xf and ancestral host species identified evolutionary events of gene gain and loss related to host range specificity. Here, by using a similar workflow, we identified two loci that are significantly found in blueberry-infecting strains. Locus_1088 included a hypothetical protein and a small part of the N-terminus of an orphan RelE toxin, while Locus_2741 was annotated as a hypothetical protein. Using a protocol based on natural competence, mutants were generated in three Xf subsp. multiplex strains from blueberry. Less biofilm, more planktonic growth, and increased twitching motility as compared to its wild-type (WT) were observed for the strain LA-Y3C_1088 mutant. In blueberry virulence assays, the LA-Y3C_1088 mutant caused significantly more severe symptoms than LA-Y3C_WT, whereas no significant differences were observed for other mutated strains. Interestingly the mutation of Locus_1088 additionally disrupted a toxin (part of a toxin-antitoxin system) that is likely responsible for the phenotypic changes observed. However, because the two independent mutants were not generated, we could not determine whether the phenotype resulted from disruption of hypothetical protein or the toxin. Additionally, since the coffee-isolated but never tested in blueberry Xf subsp. fastidiosa strain CFBP8073 was found to encode the two blueberry-associated loci studied here, its virulence was assessed in blueberry. This strain caused severe symptoms comparable to the control strain AlmaEm3 from blueberry. Due to the complexity of understanding host specificity in Xf, any advance in identifying genetic markers for host specificity in this devastating pathogen could greatly improve management of Xf worldwide.

Factors associated with return to meaningful activities following physiotherapy for pelvic girdle pain during pregnancy: 3-year follow-up of a randomised controlled trial

Por: Svahn Ekdahl · A. · Fagevik Olsen · M. · Gutke · A.
Objectives

To investigate whether women who experienced pelvic girdle pain (PGP) during pregnancy were able to engage in meaningful activities at 4 months and 3 years post partum, and to identify factors associated with long-term functional outcomes.

Design

Long-term follow-up of a randomised controlled trial comparing acupuncture and transcutaneous electrical nerve stimulation for pregnancy-related PGP.

Setting

Physiotherapy outpatient clinics in Sweden.

Participants

In total, 113 pregnant women with clinically verified PGP were randomised in the original trial; 86 participated in the initial study phase, 77 attended the 4-month follow-up and 57 completed the 3-year follow-up questionnaire.

Primary and secondary outcome measures

The primary outcome was functioning, assessed using the Patient-Specific Functional Scale (PSFS). Secondary outcomes included self-reported PGP, overall functioning and the prognostic value of pelvic pain provocation tests at 4 months post partum for persistent PGP at 3 years.

Results

3 years post partum, the mean PSFS score was 8.64, and 45.6% of the participants scored 10, indicating full return to baseline activities. In repeated linear regression analyses, estimated PSFS scores were approximately 3 points lower at baseline and post-treatment compared with the 3-year follow-up (both p

Conclusions

Most women with pregnancy-related PGP regained functioning by 4 months post partum, and this recovery was sustained at 3 years. The number of positive pelvic provocation tests at 4 months post partum predicted persistent pain at 3 years, suggesting potential prognostic value for identifying women at risk of long-term PGP and informing postpartum follow-up strategies.

Dyadic Coping, Resilience and Post‐Traumatic Growth in Young and Middle‐Aged Coronary Heart Disease Patients and Their Spousal Caregivers: An Actor–Partner Interdependence Mediation Model

ABSTRACT

Aims

This study was to explore the mediating effect of resilience on the relationship between dyadic coping and post-traumatic growth in patient–spousal caregiver dyads living with coronary heart disease (CHD).

Design

A cross-sectional study was conducted from December 2022 to June 2023.

Methods

Three hundred eighteen young and middle-aged patient–spousal caregiver dyads from a tertiary hospital in China participated. The dyadic participants were evaluated using self-report questionnaires on dyadic coping, resilience and post-traumatic growth.

Results

A significant actor effect was observed, in which dyadic coping in patients was associated with their own post-traumatic growth; this relationship was partially mediated by both the patient's and the partner's resilience. Furthermore, in the examination of partner effects, the association between dyadic coping in spousal caregivers and post-traumatic growth in patients was found to be completely mediated by the resilience of both the patients and the caregivers.

Conclusion

The findings suggest that the dyadic coping, resilience and post-traumatic growth of patients and their spousal caregivers display interactive effects. Healthcare providers treating CHD should regard patient–spousal caregiver dyads as a whole and implement interventions that focus on improving positive dyadic coping and resilience to promote post-traumatic growth.

Impact

This paper found that the patients with CHD and their spousal caregivers exhibited low levels of post-traumatic growth, with both groups demonstrating mediating and interactive effects via resilience. The findings offer valuable insights to support the early primary identification and implementation of more effective intervention strategies aimed at fostering post-traumatic growth in CHD patient–spousal caregiver dyads.

Examining social camouflaging and its cognitive, mental health and neurophysiological correlates in autistic adolescents through triangulation-based assessment using self, parent and daily diary reports: a study protocol

Por: Klein · J. · Krahn · R. L. · Howe · S. J. · Cormier · A. · Rush · J. · Ames · M. · McMorris · C. A. · Macoun · S.
Introduction

Social camouflaging (SC; ie, the concealing of autistic traits to socially assimilate) is associated with poor mental health, self-identity and quality of life outcomes, yet its typology, consequences and contextual triggers remain unexplored in autistic adolescents. Further study is necessary to identify protective factors against the potentially negative outcomes associated with SC to promote long-term well-being.

Methods

The current project will investigate SC in youth and its mental health, cognitive and neurophysiological correlates. Camouflaging will be captured by triangulating self-reported and caregiver-reported SC behaviours, as well as SC behaviours in day-to-day contexts using intensive longitudinal methods (ie, daily diaries). Non-autistic, self-identifying autistic and formally diagnosed autistic adolescents aged 15–18 years (N=150) will be recruited. Adolescents and caregivers will complete rating scales to assess mental health, and adolescents will complete in-lab cognitive assessments of attention, executive function, intellectual ability and theory of mind. Brain neurophysiological function and cortisol concentration over time will be measured during the same visit using electroencephalography and hair samples, respectively. Over the following 7 days, adolescents will complete daily diaries using their smartphones. The daily diaries pose survey questions about the type and degree of SC behaviour used within their daily environment, including the social context, individuals who are present and current well-being. Adolescents will also complete brief performance-based cognitive assessments of attention and executive function integrated within the daily diary surveys. Finally, adolescents and their parents will complete a follow-up of SC behaviours and mental health at 3 months. Correlations and regression analyses will be conducted to explore the associations between SC and mental health/cognitive outcomes and how baseline measures of cognition, mental health and SC predict patterns seen on the daily diaries. Multilevel modelling will be used, nesting daily data to capture within-person and between-group differences in contextual predictors of camouflaging behaviour. Results will contribute to current understanding of the typology of camouflaging, as well as inform intervention to mitigate mental health challenges for autistic youth.

Ethics and dissemination

This project is approved by the University of Victoria Human Research Ethics Board (#23–0013) and the University of Calgary Conjoint Faculties Research Ethics Board (#23–0641). Informed consent will be obtained from caregivers and adolescent participants, and safety procedures will be put in place to support the adolescent should mental health concerns arise. Results will be disseminated through academic publications and conferences, as well as summarised and communicated to interested participants and relevant stakeholders.

Effect of digital intervention in the self-management of depressive symptoms: the MENTINA trial - a study protocol for a randomised controlled parallel-group trial

Por: Faurholt-Jepsen · M. · Dyreholt · M. S. · Kyster · N. B. · Iversen · N. · Kortsen · E. M. · Amann · B. L. · Hogg · B. · Gatto · D. · Cordoba · C. d. · Petrovic · M. · Allenhof · C. · Schnitzspahn · K. · Reich · H. · Budtz-Jorgensen · E. · Kessing · L. V. · Hegerl · U.
Introduction

Depression and sub-diagnostic depressive syndromes are prevalent and associated with suffering and reduced life expectancy. Access to care is limited even in countries with developed healthcare systems. In this context, it is important to strengthen the self-management expertise of people suffering from depressive symptoms. Smartphones offer the possibilities for improved self-management based on long-term monitoring of symptoms.

The present multicentre randomised controlled trial (the Protecting mental health in times of change (MENTINA) trial) aims to evaluate whether (1) daily smartphone-based monitoring and automatic rule-based feedback+smartphone-based outcome evaluations versus (2) smartphone-based outcome evaluations alone will improve depressive symptoms and other clinically relevant outcomes in participants with current depressive symptoms and/or one or more prior depressive episodes during a 12-month trial period.

Methods and analysis

The MENTINA trial is a multicentre randomised controlled parallel-group trial conducted in Denmark, Germany and Spain. Participants with current depressive symptoms and/or one or more previous depressive episodes are invited to participate. The included participants will be randomised to (1) daily smartphone-based monitoring and automatic rule-based feedback+outcome evaluations via smartphone (intervention group) or (2) outcome evaluations via smartphone alone (control group). All participants can continue with ongoing treatment in case they receive it. The trial started in May 2025 and has currently included 115 participants. The outcomes are differences between the intervention group and the control group in (1) Patient Health Questionnaire 9-items (PHQ-9) measured every 14th day during the 12-month trial period (primary), (2) WHO Quality of Life-BREF, Generalised Anxiety Disorder-7, monthly change in PHQ-9, proportion of participants with ≥50% reduction in PHQ-9, remission rate defined as PHQ-9≤9 and ≥5-point improvement, PHQ-9 scores after 6 months, area under the curve for PHQ-9 over the 12 months trial period, subgroup analyses in PHQ-9 in participants with or without lifetime depression, Perceived Stress Scale, user-reported healthcare contacts, usability of the app and negative effects, number of depressive episodes+duration and depressive-free days based on PHQ-9. A total of 660 participants will be included in the MENTINA trial.

Ethics and dissemination

The MENTINA trial is funded by the European Union under Grant Agreement No. 101 080 651. Ethical approval and approval from Medical Agencies have been obtained from Denmark (CIV-25-02-051094), Germany (CIV-25-02-05109) and Spain (CIV-25-02-051094). The results will be published in peer-reviewed academic journals, presented at scientific meetings and disseminated to patients’ organisations and media outlets.

“<i>My childhood affected my ability to be resilient in both good and bad ways</i>”: A mixed methods examination on the links between adverse childhood experiences, resilience, and transactional sex among young South African women

by Deborah Baron, Nisha Gottfredson O’Shea, Alexandra Lightfoot, Caroline Kuo, Sheri Lippman, F. Xavier Gómez-Olivé, Kathleen Kahn, Audrey Pettifor, Suzanne Maman

Background

South African women are disproportionately impacted by HIV. Among these women, adverse childhood experiences (ACEs) are common and have been linked to HIV risk behaviors, including transactional sex (TS). Resilience—or multi-level processes related to overcoming adversity—provides a strengths-based lens that may buffer effects between ACEs and TS.

Methods

We conducted a convergent mixed methods study among women aged 18–25 years in Mpumalanga, South Africa. We used logistic regression to assess the association between ACEs and TS; and tested moderation effects of five resilience scales across social-ecological levels hypothesized to dampen the effect of ACEs on TS. In parallel, we conducted a photovoice study that utilized participant-generated images and narratives, and thematic and sequence analysis to explore how women exposed to ACEs perceive and use resilience to navigate TS relationships.

Results

Our analysis included 1,222 women aged 18–25 years, of whom 714 (58.43%) reported ACE exposure, with 519 (42.47%) reporting 1–2 ACEs and 195 (15.96%) reporting ≥3 ACEs; 340 (27.82%) reported TS. Women reporting ACE exposure had increased odds of TS compared to those without ACE exposure, controlling for confounders (AOR = 1.52, 95% CI: 1.17–1.99, P = 0.002). Among women with histories of ACEs, women with ≥3 ACES had 2.55 times the odds of TS than those reporting 1–2 ACEs (95% CI: 1.79–3.63, P= Conclusion

We examined the interplay between resilience, ACEs, and TS. Although quantitative results showed resilience did not buffer negative effects of ACEs on TS, the photovoice findings suggest resilience was salient and influential in women’s lives. Future research should explore resilience measures and interventions that address the complex gender and power dynamics that exacerbate women’s exposure to TS and HIV.

PhyCARE reporting guidelines for physiotherapy case reports: a consensus-based development

Por: Naqvi · W. M. · Mishra · G. V. · Shaikh · S. Z. · Pashine · A. A. · Sanchez Romero · E. A. · Swaminathan · N. · Jiandani · M. P. · Herrero · P. · Zazulak · B. · Macpherson · C. E. · Goyal · C. · Zadro · J. R. · Sahni · P. · Innocenti · T. · Quazi Syed · Z. · Hoogeboom · T. · Kiekens · C
Objectives

Case reports (CRs) are essential in physiotherapy, yet reporting remains heterogeneous and insufficiently standardised. The 2013 CAse REport (CARE) guideline improves transparency but lacks physiotherapy-specific detail. This study aimed to develop a consensus-driven extension of the CARE reporting guideline to support structured reporting of physiotherapy CRs, encompassing physiotherapy-specific assessments and interventions.

Design

An e-Delphi consensus process study following the ACcurate COnsensus Reporting Document (ACCORD) guidelines.

Setting

Online.

Participants

Forty-four international experts in physiotherapy practice, research and education, along with six core committee members.

Methods

Experts objectively scored items for relevance (5-point Likert scale) and provided open-ended responses for each item of the drafts. Scores and responses were analysed to facilitate iterative refinement of the Physiotherapy CAse REport (PhyCARE) reporting guidelines. Consensus was predetermined at over 70% agreement.

Results

Round 1 had the majority of items achieving ≥70% agreement, except two items that did not meet the threshold were revised and replaced with an alternative. Five new items addressing physiotherapy-specific reporting needs were added, and 10 items were relocated. In round 2, all 35 items across 13 domains achieved 84%–100% agreement. The nomenclature of one domain was revised to ‘Outcomes and Follow-up’. Following two e-Delphi rounds, consensus was achieved, and suggestions from online meeting, piloting led to item rephrasing, after which the PhyCARE guidelines were finalised.

Conclusion

The PhyCARE guidelines have the potential to provide a physiotherapy-specific extension of CARE to support structured, transparent and reproducible reporting of physiotherapy CRs.

Participatory development of an evaluation and data model for teleconsultations in long-term care: study protocol based on the MRC framework

Por: Woessner · S. · Hahn · L. · Kaltenbach · C. · Joos · S. · Mahler · C. · Henschke · C. · Koch · R.
Introduction

Demographic change is resulting in a growing number of individuals requiring nursing care, while the availability of professional caregivers is simultaneously declining. This imbalance places increasing pressure on care provision, particularly in home settings and rural areas. Primary care services are also under pressure. Digital solutions such as teleconsultations are considered promising strategies to support intersectoral collaboration in long-term care and to mitigate existing gaps in service provision.

Methods and analysis

Seven teleconsultation projects in long-term care are being conducted using a mixed-methods design aligned with the phases of the Medical Research Council framework: with a focus on the feasibility phase. Data on structural conditions, usage patterns and user acceptance will be collected through standardised instruments (including Unified Theory of Acceptance and Use of Technology and Fit between Individuals, Task and Technology). In addition, focus groups and interviews will be carried out. The quantitative analysis will include descriptive and inferential statistical methods and will be complemented by a cost–consequence analysis. The qualitative data will be analysed using structuring content analysis. The aim is to provide a context-informed and theory-informed assessment of the implementation and potential impact of telemedical consultations.

Ethics and dissemination

The study has been approved by the Ethics Committee in Tübingen. Participation is voluntary and based on written informed consent. Data protection is ensured in accordance with the GDPR (General Data Protection Regulation); all data are pseudonymised and processed separately. Results will be communicated in a target group-appropriate manner and published in scientific journals. Practice-oriented recommendations will be developed to support the further advancement of telemedical care in nursing.

Study protocols for the GEPard project: systematic analysis of sex- and gender-specific differences in the efficacy of perioperative pain management - a two-pronged approach

Por: Floren · S. · Segelcke · D. · Machacek · P. A. · Vollert · J. · Norda · H. · Rohde · I. · Gilron · I. · Pogatzki-Zahn · E. M.
Introduction

Postoperative pain is common, with approximately one-third of surgical patients experiencing severe acute pain and 10–20% developing chronic post-surgical pain (CPSP). Evidence shows that female patients are at higher risk of pain after sex non-specific surgery, thus sex- or gender-specific differences in pain treatment efficacy with potential consequences for perioperative pain management are to be expected. Considering the clinical and societal burden of poorly managed postoperative pain, the GEPard project comprises two systematic reviews, GEPard 1: sex- and/or gender-specific differences in efficacy of perioperative pain management for certain (major) surgical procedures in adult patients; and GEPard 2: sex- and/or gender-specific differences in the dosing, efficacy and adverse effects of the most common systemic perioperative non-opioid- and co-analgesics across all sex non-specific surgical procedures in adult patients.

Methods and analysis

The reviews will be conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook. MEDLINE, Embase, Cochrane Library, Web of Science, Scopus, ClinicalTrials.gov and PsycINFO will be searched. We will include randomised controlled trials (RCTs) and systematic reviews/meta-analyses reporting outcomes disaggregated by sex and/or gender in adult surgical patients. For GEPard 1, this applies to selected major surgical procedures; for GEPard 2, to all non-sex-specific surgical procedures. Interventions include regional anaesthesia, systemic analgesics and psychological strategies for GEPard 1 and non-opioid- as well as co-analgesics for GEPard 2. Two reviewers will independently screen and extract the data. Cochrane Risk of Bias Tool 2.0 (RoB 2) and AMSTAR 2 tools will assess study quality. Random-effects or Bayesian meta-analyses will be performed where possible; otherwise, narrative synthesis will be applied. GRADE methodology will assess evidence certainty.

Ethics and dissemination

No ethical approval is required for these reviews. Findings will be disseminated via peer-reviewed publications, patient organisations and professional societies. Data will be shared via Zenodo or Open Science Framework (OSF), following FAIR principles.

PROSPERO registration number

The systematic review protocols for both reviews have been registered in PROSPERO on 29 August 2025 (Registration-ID: CRD420251121393 (GEPard1), CRD420251121536 (GEPard2).

Quality of life in hypertensive patients using the WHOQOL-BREF instrument in the post-pandemic Bangladesh: A cross-sectional study

by Nasrin Akter, Farhana Faruque Zerin, Bilkis Banu, Fatema Afrin Kanta, Shahnaz Begam, Sarder Mahmud Hossain

Background

To combat growing prevalence of hypertension in Bangladesh, it is critical to have an in-depth understanding about quality of life (QOL) among people living with hypertension and related factors. In the recent COVID-19 pandemic the QOL of hypertensive people got downsized. This study aimed to measure QOL among hypertensive people in a selected tertiary hospital in Dhaka city, and its association with the basic characteristics of the patients.

Methods

This study was conducted among randomly selected 300 hypertensive patients from two departments of Square Hospitals Limited, using the patient register record. Data were collected through face-to-face interview methods. The WHOQOL-BREF questionnaire was used to assess the QOL of the subjects. Descriptive statistics were used to examine mean scores of quality of life. Cronbach’s alpha coefficient and Pearson’s correlation coefficient were applied to estimate the internal consistency, and the level of agreement among different domains of WHOQOL-BREF, respectively. Chi-square test followed by binary regression analysis was used to measure the association between QOL domains and independent variables.

Results

Both overall WHOQOL-BREF and each domain had a good internal consistency, (r = 0.13–0.77, p  Conclusion

The results revealed low QOL in psychological and social domain, including significant factors associated with the poor QOL in all domains. Planning and implementation of effective interventions are needed to improve QOL among hypertensive patients targeted towards aged, diabetic, lower income group who had positive COVID-19 infection and poor lifestyle through health system strengthening.

When a fall leads to a hospital emergency department visit: a focus group study on factors influencing the adoption of falls prevention measures

Por: Reeck · N. · Völkel · A. · Mammes · M. · Urbahn-Schiefer · D. · Reineking · B. · Brushinski · E. · Stuckenschneider · T. · Zieschang · T. · Brütt · A. L.
Objectives

Studies have demonstrated the positive impact of falls prevention interventions for high-risk older adults who have experienced a severe fall. However, uptake and adherence rates remain low. The purpose of this study is to assess the capabilities, opportunities and motivations of older adults following a fall with subsequent presentation to the emergency department and direct discharge home in relation to falls prevention measures.

Design and setting

This study, conducted as part of the ‘Sentinel fall presenting to the emergency department’ project at the Carl von Ossietzky University Oldenburg in Germany, involved a participatory research team (PRT). It was a qualitative study based on focus group interviews undertaken between June and October 2022, analysed in accordance with qualitative content analysis following Kuckartz. The Theoretical Domains Framework forms the basis of the deductive category system. PRT members collaborated as co-researchers in conducting and analysing the focus groups.

Participants

12 focus groups were conducted (N=52). The participants were older adults (≥60 years) who had received outpatient care in an emergency department following a fall (N=41) and their relatives (N=11).

Results

Interviewees indicated that both knowledge of available support options and the ability to self-evaluate are important following a fall. Additionally, health circumstances, such as limitations resulting from fall-related consequences, influence the adoption of falls prevention measures. Social influences, as well as environmental context and resources, were also discussed, reflecting participants’ preferences for intervention design, such as having a central point of contact and specific courses on fall training. Moreover, the fall event itself may strengthen the perceived need for preventive measures, whereas a fear of falling can lead to reduced or modified activity levels.

Conclusions

To improve the engagement of older adults in falls prevention interventions following a fall, the establishment of a central point of contact could be considered. Individual tailored interventions, including psychological support as well as specific fall training, are needed.

Post-copulatory competition in a social monogamy system: Sperm morphology correlates with components of reproductive success

by Carly E. Hawkins, Thomas P. Hahn, Jessica L. Malisch, Gail L. Patricelli

Males in socially monogamous species can achieve reproductive success through multiple tactics– by defending paternity within the social nest and siring extra-pair offspring, or both. Previous studies have found that sperm morphology may differentially affect fertilization success in extra-pair compared to within-pair matings; therefore, we explored whether sperm morphological traits can predict the probability of success within components of reproductive success. Here, we measured sperm component traits (head length and flagellum length) and derived traits (total length and flagellum:head ratio) in free-living Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) and examined how these morphological traits relate to extra-pair and within-pair reproductive components of reproductive success. We found no evidence for correlations between sperm morphology and total seasonal reproductive success. However, we did find that sperm morphology appeared to be associated with whether a male was successful at acquiring extra-pair offspring or defending his own paternity within his nest: males that achieved extra-pair success had longer flagella and longer total length of sperm cells compared to males that did not sire outside of their social nest. In contrast, males that successfully defended all paternity within their social nest tended to have shorter heads and larger flagellum:head ratios compared to males that lost paternity in their social nest. While these patterns suggest that different sperm traits may be linked to success in different components of reproductive success, they should be interpreted with caution given the exploratory nature of this study and limited sample size, and further investigation is warranted.

K-LARS trial: protocol for a multicentre randomised controlled trial evaluating a knowledge-enhanced digital intervention to prevent low anterior resection syndrome in Korea

Por: Ryoo · S.-B. · Ahn · H.-M. · Nam · B.-H. · Song · Y. M. · Sohn · D. K.
Introduction

Low anterior resection syndrome (LARS) is a common functional complication after sphincter-preserving surgery for rectal cancer that significantly impairs the quality of life. Current postoperative management strategies are suboptimal, and effective preventive approaches are lacking. This study aims to evaluate the impact of a mobile-based, knowledge-enhanced digital intervention for reducing the incidence of major LARS.

Setting

This is a multicentre, open-label, parallel-group, randomised controlled trial to be conducted across three academic medical centres in Korea.

Methods and analysis

A total of 300 adult patients who underwent low anterior resection or stoma reversal after rectal cancer surgery will be randomly assigned in a 1:1 ratio to the intervention group (mobile digital programme) or the control group (standard educational materials). The digital programme includes daily symptom monitoring, exercise suggestions, dietary recommendations and structured feedback from healthcare providers during clinical visits based on outcomes. The primary outcome is the incidence of major LARS (score ≥30) at 12 months postoperatively. Secondary outcomes include longitudinal changes in LARS score, quality of life (European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-Core 30 (C30), EORTC QLQ-Colorectal Cancer 29 (CR29)), European Quality of Life 5 Dimensions Level Version (EQ-5D-5L), patient satisfaction and programme adherence. Statistical analyses will include stratified chi-squared tests and mixed-effects models based on the intention-to-treat principle.

Ethics and dissemination

The trial received ethical approval from the Institutional Review Board of the National Cancer Centre, Korea. Written informed consent will be obtained from all participants. The findings will be disseminated through peer-reviewed publications and conference presentations.

Climate Justice Strategies Implemented by Public Health Nurses and Their Community Partners

ABSTRACT

Aim

To describe nurses' and community-based organization representatives' collaborative strategies for advancing climate justice with communities.

Design

This study used a descriptive, qualitative research design.

Methods

Data were gathered from August 2022 to February 2023 with nurses (n = 8) and their community partners (n = 5) in the United States. Community partners were representatives of community-based organizations. Photovoice provided greater context for the thematic analysis of collaborative strategies discussed in semi-structured interviews.

Results

Nurse participants worked in academic or non-profit settings. Nurse-community partnerships addressed corporate pollution and promoted Indigenous sovereignty and multispecies justice. Themes included investigating disease and health events, identifying at-risk populations and connecting them with resources, providing health teaching and counseling, organizing communities and coalitions, and advocating for policy development and enforcement. Self-care supported resilience and well-being in the long struggle for climate justice.

Conclusion

Findings from this study indicated that nurses and their community partners strategize to transition communities away from systems of extraction towards local and regenerative systems that support resilience. Nurses and their community partners recognized the importance of applying an expansive understanding of climate justice, including intersections of pollution and multispecies justice, to promoting planetary health.

Implications for the profession

Findings from this study support nurse-community collaboration in policy work to advance planetary health. This study also supports nurses' collective action with their community partners to address the effects of white supremacy and colonization. Future research is needed to evaluate the outcomes of nurse-community partnerships for planetary health.

Impact

Nurses have called for action on climate justice; however, evidence of effective nursing strategies that advance climate justice is sparse. This study is the first to describe the collaborative strategies nurses implement with community partners to support the transition from injustice to justice in communities most burdened by climate change and industrial pollution.

Clinical utility and cost-effectiveness of BeginNGS newborn screening by genome sequencing and standard newborn screening for severe childhood genetic diseases: an adaptive, international and comparative clinical trial

Introduction

In the last 60 years, newborn bloodspot screening (NBS) has expanded as a public health intervention from a single severe childhood genetic disease (SCGD) to up to as many as 80 SCGD and testing of ~40 million newborns/year worldwide. However, the gap between current NBS and its potential to increase the efficiency, effectiveness and global equity of healthcare delivery for SCGD is large and rapidly growing. There are now effective therapeutic interventions—drugs, diets, devices and surgeries—for up to 2000 SCGD. Since almost all SCGD can be identified by bloodspot genome sequencing, it has been a longstanding goal to supplement current NBS with genome sequencing-based NBS (gNBS) for all eligible SCGD. We recently described a novel gNBS platform (named Begin Newborn Genome Sequencing (BeginNGS)) with the potential to overcome several major challenges to gNBS (cost, scalability, false positives and an unprepared healthcare workforce). A pilot clinical trial of BeginNGS for 412 SCGD in a level IV neonatal intensive care unit (NICU) had a true positive rate of 4.2%, sensitivity of 83%, positive predictive value of 100% and clinical utility rate of 4.2%, indicating readiness of the platform for use in a powered, multicentre study.

Methods and analysis

The BeginNGS study is a single group, international, multicentre, adaptive clinical trial to compare utility, acceptability, feasibility and cost-effectiveness of BeginNGS gNBS (experimental intervention) with standard NBS (control). A minimum of 10 000 neonates (aged 50 000 US children per year.

Ethics and dissemination

This study was approved by the WCG Clinical institutional review board on 14 February 2024, and the most recent amendment approved on 7 October 2025 (approval number 20235517). Study findings will be shared through research consortium workshops, national and international conferences, community presentations and peer-reviewed journals.

Introduction

Heightened rates of mental illness among children, young people and forcibly displaced adults are well-documented. Despite this, access to care in host countries is often low. Problem-management plus (PM+) is an intervention developed by the WHO that can be delivered through task-shifting by lay counsellors and has been shown to be effective in numerous studies. At the same time, it has been shown that PM+ has a limited effect on traumatic stress symptoms, a common problem among forcibly displaced individuals. In turn, to further these benefits, a novel emotional processing (EP) module has been developed to be adjunctively delivered alongside PM+(PM+EP).

Method and analysis

The current study is a randomised controlled feasibility and acceptability study. 60 participants aged 16–25 will be randomly allocated to either PM+, PM+EP or care as usual. The primary outcome of this study will be the feasibility and acceptability of the delivery of PM+EP in forcibly displaced youth. Secondary outcomes are self-rated measures of distress, depression and anxiety, post-traumatic stress disorder, personally identified problems, hope, use of services and medications, general well-being and social support.

Ethics and dissemination

Following ethical approval in February 2024, recruitment commenced in October 2024. Study completion is anticipated by December 2025. Findings will be disseminated via peer-reviewed publications, conference presentations and communication with relevant stakeholders.

Introduction

Many patients who are extubated after receiving mechanical ventilation for acute respiratory failure experience extubation failure (ie, require reintubation hours to days after extubation). High-quality evidence shows that extubating patients directly to non-invasive ventilation (NIV) or high-flow nasal cannula oxygen (HFNC), rather than conventional low-flow oxygen, can prevent extubation failure. These guideline-recommended interventions, however, require care coordination involving multiple intensive care unit (ICU) team members and are infrequently used. Interprofessional education (IPE), which teaches members of multiple professions together, could effectively address this implementation gap in complex, team-based, critical care settings, particularly when paired with a customisable protocol.

Methods and analysis

This batched, stepped-wedge, cluster-randomised, type 2 hybrid effectiveness–implementation trial will test three hypotheses: (1) when compared with traditional online education (OE), IPE increases implementation of preventive postextubation respiratory support, (2) the benefits of IPE are increased when paired with a clinical protocol and (3) preventive postextubation NIV for high-risk patients and preventive postextubation HFNC for low-risk patients reduce in-hospital mortality when compared with conventional postextubation oxygen therapy. The trial will recruit 24 clusters made up of one or more ICUs that care for at least 100 mechanically ventilated patients per year in a large multihospital health system in the USA. All clusters will receive OE, IPE and a clinical protocol, with timing determined by randomisation. We will also randomise half of the clusters to education promoting postextubation NIV for patients at high risk of extubation failure and preventive, postextubation HFNC for patients at lower risk, whereas the other half will be randomised to education promoting postextubation HFNC for all eligible patients. We will include all patients who are invasively mechanically ventilated for at least 24 hours. The primary implementation endpoint is the rate of use of postextubation NIV or HFNC among eligible participants. The primary clinical endpoint is in-hospital mortality truncated at 60 days from intubation.

Ethics and dissemination

This study was approved by the institutional review board of the University of Pittsburgh and an independent data safety monitoring board. We describe the methods herein using the Standard Protocol Items for Randomised Trials framework and discuss key design decisions. We will disseminate results to participating healthcare providers, through publication in a peer-reviewed medical journal and via presentations at international conferences.

Clinical outcomes, cost-effectiveness and implementation of individualised physiotherapy using the Specific Treatment Of Problems of the Spine (STOPS) approach for chronic low back pain in Nigeria: a protocol for a prospective sequential clinical trial

Por: Danazumi · M. S. · Ford · J. · Kaka · B. · Hahne · A.
Introduction

Despite advances in the physiotherapy management of low back pain (LBP) worldwide, studies indicate that there is a large variation in the quality of physiotherapy management for LBP in Nigeria. This clinical trial aims to evaluate the implementation of individualised physiotherapy for chronic LBP in Nigeria using the Specific Treatment Of Problems of the Spine (STOPS) approach.

Methods and analysis

This will be an implementation clinical trial using a non-randomised, prospective, sequential comparison design. One hundred and fifty-four participants with chronic LBP will be recruited at one hospital in Nigeria. In phase I, participants will receive 11 sessions of usual physiotherapy care. In phase II, consenting physiotherapists will undergo training in the implementation of the STOPS treatment approach, led by the original Australian developers. In phase III, participants will receive 11 sessions of individualised physiotherapy using the STOPS approach. Patient evaluation in phases I and III will be measured at baseline and at 5, 10, 26 and 52 weeks, and will evaluate the clinical outcomes (including primary outcomes of pain intensity measured with a 0–10 Numerical Rating Scale, and activity limitation measured via the Oswestry) and cost-effectiveness from the healthcare perspective (incremental healthcare costs relative to incremental quality adjusted life-years gained on the EuroQOL-5D-5L). Physiotherapist outcomes will include confidence in treating LBP and implementation behaviour measured at the start of phase I and at the end of phases I, II and III. Implementation feasibility and qualitative analysis of patient and physiotherapist experiences will also be explored.

Ethics and dissemination

The trial has been approved by the Human Research Ethics Committees of La Trobe University, Australia (HEC22278) and Federal Medical Centre (FMC) Nguru, Yobe State, Nigeria (FMC/N/CL.SERV/355/VOL IV/131). The study results will be shared through peer-reviewed journals and conferences.

Assessing the Relationship Between Knowledge, Attitude, and Practice Regarding Elder Abuse With Caring Behaviours Assessment Among Nurses: An Exploratory Study

ABSTRACT

Aims

This study aims to explore the relationship between nurses' knowledge, attitudes, and practices regarding older adult abuse and their caring behaviours, focusing on Iranian nurses.

Design

A cross-sectional exploratory study.

Methods

A cross-sectional correlational design included 250 nurses from medical education centres in Ardabil. A three-part questionnaire assessed demographic characteristics, knowledge, attitudes, and practices regarding elder abuse and caregiving. Data were collected from August to October 2024 and analysed using ANOVA, t-tests, Pearson correlations, and multiple regression analysis.

Results

The study's findings are significant, revealing a moderate level of knowledge among nurses about older adult abuse. There are significant positive correlations between knowledge, attitudes, and caring behaviours, with higher education levels associated with better caring behaviours. However, practice scores did not align with knowledge and attitudes, indicating barriers such as workload and lack of training.

Conclusion

The findings reveal a significant link between nurses' knowledge and attitudes toward older adult abuse and their caring behaviours. Positive attitudes are associated with higher Caring Behaviours Assessment scores, suggesting that educational programs should enhance nurses' understanding and empathy toward older adult care. Addressing the identified gaps in knowledge and practice can lead to improved patient outcomes and a more compassionate healthcare environment for older adults. It is crucial to provide continuous training and support to empower nurses to apply their knowledge in practice effectively.

Impact

The study highlights the necessity for regularly occurring targeted educational interventions to enhance nurses' understanding of older adult abuse. Implementing continuous professional development programs for nurses can significantly improve patient outcomes and reduce instances of abuse. Healthcare organisations should foster supportive environments that encourage the regular reporting of suspected cases of abuse and ensure that nurses are consistently updated on best practices. Increasing community awareness about elder abuse is crucial for safeguarding vulnerable older adults.

Reporting Method

EQUATOR guidelines were followed using the STROBE reporting method.

Patient or Public Contribution

This study did not include patient or public involvement in its design, conduct, or reporting. Only nurses were involved in data collection.

Barriers to and Facilitators of Shared Decision‐Making Implementation in Fertility Preservation for Patients With Cancer: A Qualitative Study

ABSTRACT

Introduction

To identify the barriers and facilitators in the implementation of fertility preservation (FP) shared decision-making (SDM) in oncology care.

Design

Qualitative descriptive study.

Methods

Qualitative interviews with 16 female patients with cancer and seven healthcare providers were conducted between July 2022 and April 2024. Data were analyzed using directed content analysis, guided by the implementation science framework.

Results

We identified 22 categories comprising 38 codes as barriers to SDM implementation and 17 categories comprising 26 codes as facilitators. Findings revealed that, at the innovation level, accessibility, feasibility, interdisciplinary collaboration, and quality improvement efforts were decisive in the implementation of FP SDM. At the individual level, healthcare providers' awareness and attitudes towards FP and SDM, as well as patients' knowledge, attitudes, and capabilities in FP SDM, were crucial factors in the implementation of FP SDM. In social, economic, and organizational contexts, support from significant others, social awareness about FP, multidisciplinary care, financial assistance, and educational resources were determinants in implementing FP SDM.

Conclusion

Implementing FP SDM among female patients with cancer necessitates a strategic approach that considers barriers and facilitators. Educating and promoting FP SDM among the public and healthcare providers, combined with incentivizing policies, can enhance individual knowledge and awareness while achieving systemic improvements, facilitating its successful implementation.

Clinical Relevance

This study provides insights into barriers and facilitators and proposes strategic approaches to enhancing FP SDM implementation, contributing to improved quality of life for cancer survivors and advancements in clinical practice.
