Integrating sequence-based GWAS and comparative genomic analysis reveals conservation and species-specificity of putative functional variants influencing tail length and tail abnormalities in pigs and sheep

by Xuying Zhang, Johanna Mainzer, Isabella Giambra, Tong Yin, Petra Engel, Hannah Hümmelchen, Henrik Wagner, Axel Wehrend, Christiane Egerer, Katharina Gerhards, Gerald Reiner, Sven König

Long tails trigger tail biting in pigs and increase the risk of flystrike infections in sheep. Tail docking has been a common management practice in both species for decades, but increasingly conflicts with legal animal welfare guidelines. Sustainable solutions require breeding strategies targeting shorter tails. In consequence, the aims were to conduct whole-genome sequencing (WGS)-based genome-wide association studies (GWAS) and comparative genomic analyses (CGA) to explore functional elements influencing tail traits. Phenotypically divergent experimental populations of pigs and sheep were established through unified selection and mating experiments. Tail traits included tail length (TL) measured at birth, and tail abnormalities (TA) assessed radiographically at 14 weeks of age. WGS-based GWAS identified a significant locus on SSC18 in pigs and suggestive loci for TL in both species, which, together with previously reported loci for TA, were further analyzed by CGA. The genomic windows of the significant locus on SSC18 in pigs and the TL GWAS locus on OAR4 in sheep were found to be conserved, harboring six common genes with predicted functional variants. These variants were jointly associated with TL (Plm) in both species in linear regression models adjusted for sex, age of the dam, body length, and body weight. In other GWAS locus windows (±1 Mb), species-specific TL candidate genes were identified in sheep (HOXB13, MUC5B, EPB41L3, MTCL1, PIEZO2, MPPE1, and LOXHD1) and in pigs (KNL1, DISP2, SPRED1, TGFB2, and HAND1), each harboring associated putative functional variants. For TA, sheep-specific candidates (PGM2, LRRC66, CRACD, LOC105601916, and SH2D4B) and pig-specific candidates (MYOT, TMCO6, and PCDHAC2) were revealed using logistic regression models (Pglm). GO analyses of candidate genes predicted shared biological processes between sheep and pigs, whereas pathway analyses indicated that common carbohydrate metabolism pathways, along with species-specific immune and inflammatory signaling, and pig-specific TGF-β signaling and endochondral ossification, may contribute to tail length variation and abnormalities. These findings provided deeper insights into the genetic basis of differential embryonic tail morphogenesis and perinatal tail development across species.

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.

Comparative effectiveness and safety of digital health delivery models for pulmonary rehabilitation in patients with chronic obstructive pulmonary disease: a protocol for systematic review and network meta-analysis of randomised controlled trials

Por: Xu · L. · Chen · X. · Yang · C. · Feng · M. · Wu · Y. — Marzo 3rd 2026 at 13:40
Introduction

Chronic obstructive pulmonary disease (COPD) affects approximately 480 million individuals globally and is projected to reach 600 million by 2050, representing a substantial burden on healthcare systems and patient quality of life. Pulmonary rehabilitation is a cornerstone intervention for COPD management, delivering clinically meaningful improvements in exercise capacity, health-related quality of life and dyspnoea. Despite strong guideline recommendations and established efficacy, only 2%–4% of eligible patients with COPD access traditional centre-based pulmonary rehabilitation due to geographical barriers, transportation difficulties, scheduling conflicts and limited healthcare resources. Digital health technologies offer promising alternatives to overcome these access barriers while potentially maintaining therapeutic benefits. Various digital delivery models have emerged, including video-based telerehabilitation, virtual reality platforms, mobile health applications and web-based programmes. However, their comparative effectiveness remains unclear, limiting evidence-based clinical decision making. This systematic review and network meta-analysis will aim to compare and rank the effectiveness and safety of different digital health delivery models for pulmonary rehabilitation in patients with COPD, providing evidence to inform optimal intervention selection in clinical practice.

Methods and analysis

We will conduct a systematic review and Bayesian network meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Network Meta-Analyses guidelines. Comprehensive searches will be performed across five electronic databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL) from inception to January 2026, without language restrictions. Eligible studies will include randomised controlled trials comparing digital health delivery models for pulmonary rehabilitation in adults with COPD. Digital health interventions will be categorised into four distinct delivery models: video-based telerehabilitation, virtual reality rehabilitation, mobile health rehabilitation and web-based platform rehabilitation. Interventions combining multiple modalities will be categorised according to the predominant component based on intervention frequency, duration and primary therapeutic mechanism. Two independent reviewers will perform study selection, data extraction and risk of bias assessment using the Cochrane Risk of Bias 2 tool. The primary outcome will be change in 6 min walk distance. Key secondary outcomes will include disease-specific quality of life measures, dyspnoea severity, hospitalisation rates, exacerbation frequency, intervention adherence and adverse events. A Bayesian random-effects network meta-analysis will be conducted, calculating mean differences or ORs with 95% credible intervals. Treatment rankings will be estimated using surface under the cumulative ranking curve probabilities. Evidence certainty will be assessed using the Confidence in Network Meta-Analysis framework. Planned subgroup analyses will explore potential effect modifiers including disease severity, intervention duration, supervision mode and technological features.

Ethics and dissemination

As this systematic review will use data from previously published studies, formal ethical approval is not required. Findings will be disseminated through peer-reviewed publication, presentations at relevant scientific conferences and communication to healthcare providers, policymakers and patient advocacy organisations.

Use of wearable technology in improving emergency care and health outcomes for patients with urgent health complaints: protocol for a scoping review

Por: Alotaibi · R. · Alghaith · A. · Noehrer · L. H. · Kitchen · G. B. · Body · R. — Marzo 3rd 2026 at 13:40
Introduction

Since the 1970s, telemedicine has transformed significantly, becoming a critical component of modern healthcare delivery. Over time, technological innovation has increasingly emphasised the integration of the human body with digital systems to develop non-invasive methods for monitoring physiological parameters. Among these technologies, wearable sensors demonstrate substantial potential for continuous patient monitoring. These devices can facilitate real-time data collection, enable more rapid clinical decision-making and promote active patient participation in health management. Such capabilities are particularly valuable in emergency contexts, including prehospital care provided by ambulance services and telephone triage systems. Despite the growing interest in wearable health technologies, their integration into emergency medical services (EMS) remains insufficiently explored and warrants further investigation. We aim to map current research, explore the use of wearables in EMS settings and identify gaps in knowledge regarding their use in EMS.

Methods and analysis

This scoping review will follow the Joanna Briggs Institute’s (JBI) methodology for scoping reviews. A systematic search of relevant databases (MEDLINE, EMBASE, Cochrane Library, CINAHL, ProQuest and Web of Science) will be conducted, from inception to March 2026. All types of study designs, including quantitative and qualitative studies, will be considered in this scoping review. The inclusion is limited to studies published in English. Two independent reviewers (RA and AA) will conduct a thorough screening of titles and abstracts against the predefined inclusion criteria. Studies that meet the inclusion criteria will be reviewed in full text. Quality and risk of bias will be assessed using the JBI’s critical appraisal tools for the relevant study types. The findings will be presented using diagrams or tables, supplemented by narrative summaries following the JBI guidelines.

Ethics and dissemination

Ethical approval is not required. The findings of this study will be disseminated via publication in a peer-reviewed journal.

Wound Management and Surgery for Calcific Uremic Arteriolopathy (Calciphylaxis): A Retrospective Observational Cohort Study

ABSTRACT

Wound care in calciphylaxis remains poorly defined without evidence-based consensus on timing and technique of surgical intervention. We demonstrate that surgical debridement and subsequent wound closure are safe and effective in calciphylaxis and describe a systematic multidisciplinary approach to intervention. We retrospectively reviewed a cohort of patients with calciphylaxis at our institution. Those who underwent surgical debridement and wound closure were analysed with emphasis on wound healing, progression to amputation and mortality. Sixty-two patients with calciphylaxis underwent surgical debridement. Twenty patients had wound closure by skin grafting, five were excised with primary wound closure, and 37 were debrided and allowed to heal by secondary intention. There were excellent rates of healing in all groups, and no patients demonstrated wound progression or new lesions following operative intervention. Surgical debridement and wound closure are safe and effective in treating wounds related to calciphylaxis.

by Yaosen Du, Yiyong Yang, Xiaolong Wu, Pengju Gao, Hanchen Ma

To enhance the efficiency, safety, and data accuracy of drilling engineering, this study developed an integrated business management platform for drilling engineering grassroots units based on the Business Model Driven (BMD) approach. The platform is built on a “five horizontal, three vertical” cloud computing architecture, establishing a five-layer system from the infrastructure layer to the user layer horizontally, and supported by standard specifications, safety, and maintenance systems vertically, enabling collaboration across multiple business scenarios and data integration. Currently, four major modules with over 20 functionalities have been developed, supporting applications such as task coordination, engineering supervision, data analysis, and accident handling. Operational results demonstrate that the platform effectively promotes integrated management of drilling engineering through real-time data sharing, full-process quality control, and intelligent decision-making, thereby enhancing operational quality and safety, reducing accident risks, and providing critical technological support for the digital transformation and upgrading of the drilling industry.

Study protocol for a randomised controlled trial to evaluate the prophylactic efficacy of combined intense pulsed light (IPL) and low-level light therapy (LLLT) in preventing laser corneal refractive surgery-induced dry eye: the Treat Eye Before Laser ind

Por: Kerkouri · S. · Garcin · T. · Cochener · B. — Febrero 26th 2026 at 13:47
Introduction

Laser corneal refractive surgery is a widely adopted approach for correcting refractive errors, but postoperative dry eye remains a common side effect. Intense pulsed light (IPL) and low-level light therapy (LLLT) are two emerging treatments that have shown potential in managing dry eye disease. However, their role as a prophylactic treatment in patients without pre-existing symptomatic dry eye undergoing refractive surgery has not been explored.

Methods and analysis

This is a single-blind, randomised controlled trial comparing the prophylactic efficacy of combined IPL and LLLT treatment versus standard care in preventing dry eye after laser corneal refractive surgery (FS-LASIK, SMILE or PRK). Eligible patients aged 18 or older scheduled for surgery will be randomly assigned in a 1:1 ratio to either the treatment or control group. The primary endpoint is the French version of Ocular Surface Disease Index score at 1 month postoperatively. Secondary outcomes include Fluorescein Break-Up Time, Schirmer I test, Oxford score and Meibomian Gland Dropout. Data will be analysed using a mixed-effects linear model adjusted for surgery type and baseline dry eye parameters. The study started in June 2023 and end in April 2025 but data have not been yet analysed.

Ethics and dissemination

The study has been approved by the Institutional Review Board Est III, France, and registered on ClinicalTrials.gov (NCT05803798). All participants will provide written informed consent. Results will be disseminated through peer-reviewed publications and presentations at scientific conferences.

Multicentre, open-label, prospective, parallel-controlled study protocol evaluating the effects of amino acid peritoneal dialysis solution on nutritional status in Chinese peritoneal dialysis patients

Por: Zhou · J. · Jiang · W. · Zhang · X. · Shi · J. · Ai · L. · Xia · C. · Lin · F. · Xiang · X. · He · Q. · Chen · H. · Hu · S. — Febrero 26th 2026 at 13:47
Introduction

Peritoneal dialysis (PD) is a widely used renal replacement therapy for chronic kidney disease patients, yet malnutrition remains a common complication linked to poor outcomes. Nearly 40% of PD patients in China are malnourished, with serum albumin levels below 35 g/L. Amino acid-based peritoneal dialysis solutions (AA-PDS), which replace glucose with amino acids as the osmotic agent, have been used globally for decades to improve nutrition and reduce peritoneal damage, but they were introduced to mainland China only in 2022. This study aims to evaluate the efficacy and safety of AA-PDS in improving nutritional status and clinical outcomes among malnourished PD patients in mainland China, providing a potential new therapeutic option for this population.

Methods and analysis

This multicentre, open-label, prospective, parallel-controlled study will enrol patients with end-stage kidney disease who were stable on PD for more than 3 months. A total of 500 eligible patients will be divided into the intervention group undergoing PD once every morning using 2.0 L of amino acid (15) PD solution and the control group using conventional PD solution (lactate) in a 4:1 ratio based on their willingness and clinical needs. Our primary outcome is serum albumin, while other nutritional indicators, including serum prealbumin, serum transferrin, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and ultrafiltration volumes are considered secondary outcomes. Information such as demographics, clinical and biochemical characteristics, examination indicators, anthropometry measurements and Subjective Global Assessment scores will be collected at baseline, 1 month, 3 month and 6 month follow-up. Statistical analysis will be conducted using SAS V.9.4 or higher versions. All statistical tests are conducted through the two-tailed test, and a p value≤0.05 will be considered statistically significant. The description of quantitative indicators will be used in calculating the number of cases, mean, SD, median and IQR method. The classification indicators will be used to describe the number of cases and percentages (frequency and frequency rate).

Ethics and dissemination

This multicentre study obtained ethical approval from the lead ethics committee at the First Affiliated Hospital of Zhejiang Chinese Medical University (approval no.: 2024-KLS-379-02). Additionally, each participating site provided local ethical approval or a formal waiver, as required by their institutional policies. The results will be reported in a peer-reviewed journal and a relevant academic conference.

Effectiveness of exoskeleton training on turning-while-walking and balance control in subjects with incomplete spinal cord injury: protocol for a randomised clinical trial

Por: Chen · M. · Chan · C. W.-n. · Wang · P. Y. · Tsang · W. W.-n. — Febrero 26th 2026 at 13:47
Introduction

Individuals with incomplete spinal cord injury (iSCI) often experience impaired balance control and turning-while-walking ability, which increase the risk of falls and limit their community mobility. While overground exoskeleton training has shown promise in improving gait and balance, evidence from randomised controlled trials (RCTs) on ambulation of individuals with iSCI remains limited. This protocol outlines a cluster RCT investigating the effectiveness of overground exoskeleton-assisted gait training compared with conventional training and usual care in improving turning-while-walking performence, balance control, and functional mobility in individuals with iSCI.

Methods and analysis

This multicentre, cluster RCT will compare 12-week interventions across three groups: (1) overground exoskeleton training group, (2) conventional training group and (3) usual care group. Participants with ambulatory iSCI will be recruited from three centres in Hong Kong SAR and mainland China. Primary outcomes include turning duration and number of steps during a 2-m turning-while-walking test. Secondary outcomes include static and dynamic balance, sensorimotor integration, gait performance, muscle strength, spasticity, quality of life, self-efficacy and fall incidence. Assessments will be conducted at baseline, mid-intervention, postintervention and at the 1-month follow-up.

Ethics and dissemination

This study has received approval from the Research Ethics Committees of Hong Kong Metropolitan University, the Affiliated BenQ Hospital of Nanjing Medical University, and Changzhou Sunshine Rehabilitation Hospital. Written informed consent will be obtained from all participants before enrolment. Study findings will be shared through peer-reviewed publications, conference presentations and summaries available to participants upon request.

Associations of oxidative balance score with mortality and cardiovascular events: cohort study from NHANES and UK Biobank

Por: Zhang · H. · Chen · S. · Bai · X. · Zhou · X. · Zhang · F. · Wang · X. · Chen · L. · Wang · X. — Febrero 26th 2026 at 04:41
Objective

To investigate the associations of oxidative balance score (OBS) with all-cause mortality, cardiovascular mortality and cardiovascular disease (CVD) incidence in two large, population-based cohorts.

Design

Cohort study and cross-sectional study were used.

Setting

The US National Health and Nutrition Examination Survey (NHANES) and the UK Biobank.

Participants

A total of 33 566 adults from NHANES (1998–2018) and 55 760 adults from the UK Biobank were included.

Main outcome measures

All-cause mortality, cardiovascular mortality and CVD. Mortality outcomes were ascertained through national death registries. Prevalent CVD was identified in NHANES through questionnaire, and incident CVD events were identified in the UK Biobank using linked hospital admission and death registry data.

Results

Higher OBS was consistently associated with lower all-cause and cardiovascular mortality in both cohorts. In NHANES, participants in the highest OBS quartile (Q4) had a 39% lower risk of all-cause mortality (adjusted HR: 0.61, 95% CI 0.52 to 0.72) and a 45% lower risk of cardiovascular mortality (adjusted HR: 0.55, 95% CI 0.41 to 0.74) compared with those in Q1. Similarly, in the UK Biobank, Q4 was associated with an 18% lower risk of all-cause mortality (adjusted HR: 0.82, 95% CI 0.74 to 0.91) and a 41% lower risk of cardiovascular mortality (adjusted HR: 0.59, 95% CI 0.4 to 0.87). In NHANES, Q4 was associated with lower odds of prevalent CVD (adjusted OR: 0.56, 95% CI 0.46 to 0.67), whereas in the UK Biobank, Q4 was associated with a 19% lower risk of incident CVD during follow-up (adjusted HR: 0.81, 95% CI 0.74 to 0.9). Subgroup analyses in NHANES indicated heterogeneity by ethnicity and socioeconomic status, whereas associations in the UK Biobank followed an L-shaped pattern with a flattening of estimated risk at moderate OBS levels.

Conclusion

Higher OBS was associated with more favourable mortality and cardiovascular outcomes. These findings indicate that OBS is a composite indicator associated with cardiovascular health at the population level.

Generative artificial intelligence in dementia care: a scoping review protocol on nursing roles, experiences and ethical perspectives

Por: Chen · Y.-C. · Nieh · H.-C. · Chen · H.-C. · Chen · J.-C. · Chang · M.-Y. · Wu · P.-O. — Febrero 24th 2026 at 16:52
Introduction

Generative artificial intelligence (GAI), including large language models and multimodal generative systems, is rapidly emerging in healthcare with growing interest in its potential applications for dementia care. These technologies offer new possibilities for communication support, cognitive engagement and personalised interaction, yet they also introduce complex ethical, relational and practical challenges. Nurses—who hold central, sustained roles across dementia care settings—are key mediators of technology adoption and are positioned to assess the appropriateness, safety and ethical implications of GAI use. However, existing literature remains fragmented and largely focused on technological development or patient-facing outcomes, with limited synthesis of nurses’ roles, experiences and ethical perspectives. This scoping review aims to map the current evidence regarding how nurses engage with GAI in dementia care and to identify gaps that may inform practice, policy and future research.

Methods and analysis

This review will follow the methodological framework of Arksey and O’Malley, refined by Levac et al and guided by the Joanna Briggs Institute Manual for Evidence Synthesis. Reporting will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. The review will be conducted between March 2026 and October 2026, encompassing database searching, screening, data charting, synthesis and reporting. A comprehensive search will be conducted across MEDLINE (Ovid), CINAHL, PsycINFO, Scopus and Web of Science using controlled vocabulary and keywords related to nursing, generative artificial intelligence and dementia. Eligible sources will include empirical studies, reviews, conceptual papers and policy analyses that report nursing roles, experiences or ethical considerations related to GAI in dementia care. Two reviewers will independently screen titles/abstracts and full texts and extract data using a structured charting form. Findings will be synthesised through descriptive statistics and inductive thematic analysis, supported by conceptual mapping to illustrate relationships among GAI types, nursing roles, ethical concerns and care settings. Critical appraisal will not be undertaken, as it is optional in scoping reviews and is not aligned with the primary mapping objectives of this review.

Ethics and dissemination

Ethical approval is not required as the review synthesises publicly available literature. Should the optional interest-holders consultation be undertaken, ethical clearance will be obtained from an appropriate institutional review board prior to participant engagement. Findings will be disseminated through peer-reviewed publication, conference presentations and knowledge-translation outputs targeted at clinicians, educators, policymakers and AI developers. The review will support informed, ethically grounded integration of GAI in dementia care.

Neoadjuvant hepatic arterial infusion chemotherapy (HAIC) with GEMOX and lenvatinib in combination with adebrelimab for resectable high-risk recurrent intrahepatic cholangiocarcinoma (ICC): study protocol of the NEO-ERA-01 feasibility trial

Por: Cheng · Y. · Xia · J. · Chi · Y. · Rao · J. · Cheng · F. · CLEAP China Liver Cancer Study Group Young Investigators (CLEAP) — Febrero 23rd 2026 at 12:58
Introduction

Intrahepatic cholangiocarcinoma (ICC) has a high recurrence rate after curative surgery, with no standard neoadjuvant therapy. Hepatic arterial infusion chemotherapy (HAIC) has shown efficacy in locally advanced ICC, while immune checkpoint inhibitors and anti-angiogenic agents have demonstrated promising response rates. The NEO-ERA-01 study evaluates the feasibility of neoadjuvant HAIC-GEMOX plus lenvatinib and Adebrelimab in high-risk resectable ICC.

Methods and analysis

NEO-ERA-01 is a prospective, multicentre, phase II trial using Simon’s two-stage design. Thirty patients with histologically confirmed resectable ICC and high-risk recurrence factors will be enrolled in China. Neoadjuvant therapy consists of HAIC-GEMOX (gemcitabine 800 mg/m², oxaliplatin 85 mg/m² every 3 weeks), lenvatinib (8 mg/day from Day 5) and Adebrelimab (1200 mg on Day 3, every 3 weeks) for 2–4 cycles. Surgery eligibility will be assessed post-treatment. Resected patients will receive adjuvant capecitabine (1250 mg/m² two times per day on Days 1–14, every 3 weeks) and Adebrelimab (1200 mg on Day 1, every 3 weeks) for 6 months.

The primary endpoint is the completion rate of study treatment. Secondary endpoints include safety, R0 resection rate, response rate, event-free survival, disease-free survival and overall survival. Exploratory endpoints include immune microenvironment and biomarker analysis.

Ethics and dissemination

The study is approved by the ethics committee of all sites and follows the Declaration of Helsinki and good clinical practice guidelines. Results will be disseminated via peer-reviewed publications and conferences.

Optimising electroacupuncture parameters for post-stroke hand dysfunction: protocol for a multi-arm randomised controlled trial using orthogonal design

Por: Sharma · A. · Han · L. · Deng · H. · Sun · W. · Wang · F. · Zhang · C. · Zhang · W. · Zhang · Y. · Li · L. · Guo · H. · Meng · Y. · Chen · Y. · Hou · J. · He · J. — Febrero 23rd 2026 at 12:58
Background

Hand dysfunction following stroke, especially during the flaccid paralysis phase, significantly impairs patients’ motor abilities and daily functioning. Electroacupuncture (EA) is widely used in post-stroke rehabilitation; however, inconsistent clinical outcomes and lack of standardised treatment parameters have limited its broader adoption.

This protocol describes a randomised controlled trial designed to determine optimal EA parameters for post-stroke hand dysfunction using an orthogonal experimental design.

Methods/design

This protocol presents a single-centre, randomised controlled trial design with 10 arms. A total of 110 patients with post-stroke hand dysfunction will be randomly assigned to nine electroacupuncture groups or one sham acupuncture group in equal proportions. Participants will receive 12 treatment sessions over 2 weeks. The EA groups are designed based on a four-factor, three-level orthogonal design to systematically evaluate the main effects of acupoint selection, stimulation frequency, needle thickness and treatment duration. The primary outcome is the effective response rate, defined as reduction in the Chinese Stroke Scale (CSS) score at 2 weeks. Secondary outcomes include assessments with the Modified Lindmark Rating Scale, range of motion measures, Modified Barthel Index and hand motor subscores of the CSS. As this is a trial protocol, results are not yet available. Statistical analyses will be conducted after completion of recruitment and follow-up according to the prespecified analysis plan. Safety and adverse events will be monitored throughout the study.

Conclusion

This trial is designed to address the current lack of evidence-based standardisation of EA parameters for post-stroke hand dysfunction. By systematically evaluating key treatment components using an orthogonal experimental design, the study aims to identify optimal EA strategies and provide a methodological framework to improve consistency, reproducibility and clinical effectiveness in post-stroke hand rehabilitation.

Ethics and dissemination

This manuscript describes a study protocol and does not report any data from participants at this stage. Ethical approval for the planned trial was obtained from the Medical Ethics Committee of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine (Approval No. TYLL2024(K)072). Written informed consent will be obtained from all participants prior to enrolment. The results of the study will be disseminated through peer-reviewed journals and academic conferences.

Factors influencing patient involvement in treatment decision-making for diabetic retinopathy: a mixed methods study protocol

Por: Xu · L. · Zhang · H. · Shen · Y. · Pu · J. · Wu · Q. · Chen · L. — Febrero 23rd 2026 at 12:58
Introduction

The diversity of treatment options for diabetic retinopathy (DR) and the high uncertainty about the benefits and risks of different treatment modalities necessitate shared decision-making between patients and healthcare professionals. However, little is known about the involvement of individuals with DR in treatment decision-making in China. This study aims to gain insight into the current status and factors associated with involvement in treatment decision-making in patients with DR. Furthermore, we will explore the experiences and perceptions of patients with DR regarding their involvement in treatment decision-making.

Methods and analysis

We will conduct a mixed-method study using an explanatory sequential design. In the quantitative research (n=350), participants’ actual decision-making roles, sociodemographic data, disease-related data, health literacy, need for involvement in decision-making, decision-making self-efficacy, social support and ophthalmologist facilitation of patient involvement will be investigated to analyse the current state of patient involvement in treatment decision-making and the factors influencing it. Descriptive statistics, one-way analysis of variance and multinomial logistic regression will be performed. During this period, individual semistructured interviews will be conducted with a subset of these participants to understand the perceptions and experiences of people with DR regarding their involvement in treatment decision-making, and thematic analysis will be used to analyse the interview data. Finally, the joint display will be used to integrate quantitative and qualitative data.

Ethics and dissemination

Ethical approval for this study has been obtained from the Ethical Review Committee for Human Trials of Shanghai General Hospital, China (number: 2024–098). Written informed consent will be obtained from all participants after they have been fully informed about the study, prior to any data collection. The study’s findings will be disseminated through peer-reviewed publications and conference reports.

Bereavement practices within older adult care homes in Scotland: a focus group study

Por: Drummond · M. · Burton · J. · MacEachen · D. · Johnston · B. M. — Febrero 23rd 2026 at 12:58
Objective

To describe how care home staff experience bereavement and their perspectives on providing bereavement care within care home settings.

Design

Qualitative descriptive study using focus groups analysed with the Framework Method.

Setting

Seven residential and nursing care homes for older adults in Scotland.

Participants

37 care home staff were recruited through the Enabling Research In Care Homes (ENRICH) Scotland research network. Participants included registered nurses, care workers, senior care workers, managers and ancillary workers with experience of resident death and bereavement practice.

Results

Bereavement was woven through everyday care home life, understood as a tapestry of experiences, relationships and practices that involved staff, residents and their relatives. Three themes that connected to the tapestry metaphor were identified: Warps: structural threads grounding bereavement within the culture of homely living, where close bonds normalise death and dying, and pragmatic acceptance. Wefts: strengthening practices nurturing resilience, including relational trust, mutual support, rituals and follow-up with relatives. Moths: disruptions undermining bereavement practice include family secrecy, hospital deaths with withheld information, difficulty supporting residents with advanced dementia and dissatisfaction with online training.

Conclusions

Bereavement in care homes is collective, relational and embedded in routine practice. Organisational recognition of grief improved interservice communication. Tailored reflective support for staff is needed to sustain compassionate care. Further research should explore how residents experience repeated exposure to death and bereavement within communal living environments.

Effect of preoperative liposomal bupivacaine single-injection pericapsular nerve group (PENG) block on lower extremity deep vein thrombosis in elderly patients with hip fractures: a randomised controlled, double-blind, prospective clinical study protocol

Por: Peng · H. · Wen · J. · Chen · M. · Jiang · Y. · Ou · J. · Wu · X. — Febrero 22nd 2026 at 18:08
Introduction

Deep vein thrombosis (DVT) of the lower limbs has a significantly higher incidence among elderly populations than that observed in other types of fractures, prolonged immobilisation and the systemic inflammatory response triggered by preoperative pain are the main risk factors. Liposomal bupivacaine (LB) single-injection pericapsular nerve group (PENG) block has demonstrated effective analgesia both before and after surgery, while preserving motor function in patients with hip fracture. Although regional nerve block is a well-established component of preoperative multimodal analgesia, its potential role and underlying mechanisms in the prevention of DVT in elderly patients with hip fracture remain largely unexplored.

Por: Wang · M. · Sun · S. · Guo · M. · Qian · J. · Sun · Y. · Chen · M. · Yu · X. — Febrero 22nd 2026 at 18:08
Objectives

Mentoring has been identified as a promising strategy for implementing and sustaining evidence-based practice (EBP) in healthcare organisation. However, no appropriate tools were specifically developed or cross-culturally adapted into Chinese context to assess nurse’s perceived EBP mentoring, impeding comprehensive evaluation of the effects of mentoring intervention studies. This study aimed to cross-cultural adapt the Evidence-Based Practice Mentoring (EBPM) scale into Mainland China and evaluate its psychometric properties, including validity and reliability.

Design

A comprehensive translation and adaptation process was adopted to achieve the Chinese version of the EBPM (C-EBPM) scale. It consists of four steps: (1) trilateral translation procedure, (2) cognitive interview, (3) psychometric testing and (4) cross-time confirmatory factor analysis (CFA).

Setting

This study was conducted in four 3A-level hospitals located in Shaanxi and Zhejiang provinces, China, during two different data collection periods.

Participants

A total of 598 registered nurses participated in this study.

Results

After two rounds of the trilateral translation procedure, a 9-item version of the C-EBPM scale was generated. Ten registered nurses participated in cognitive interview understood the meaning of all items but the response options. All items had significant critical ratio values (t=15.866~20.584, p²/df=65.681/27 0.950, Tucker-Lewis Index=0.966 > 0.950, and standardised root mean square residual=0.026 0.70) and average variance extracted was 0.60 (>0.50).

Conclusions

The 9-item C-EBPM scale demonstrated robust reliability and validity and is suitable for assessing EBP mentoring among nurses.

Ozone exposure and semen quality in low-income men with unhealthy behaviours in Foshan, China: a case-control study

Por: Chen · W. · Zou · H. · Shui · H. · Luo · L. · Jiang · Y. · Wan · Z. · Yue · Q. · Li · Q. · Liu · W. · Liu · W. — Febrero 19th 2026 at 12:57
Objective

To assess the association between ambient ozone (O3) exposure and semen quality among men with unhealthy behaviours and low income.

Design and setting

A case-control study was conducted from February 2024 to January 2025, in which male participants aged 18–45 years were recruited from Foshan, and following propensity score matching, a total of 820 participants were included in the final analysis.

Methods

The evaluated the association between O3 exposure during the 70–90 days, 10–14 days, 0–9 days and 0–90 days prior to semen collection and semen quality using stepwise conditional logistic regression analyses, and restricted cubic splines were incorporated into the models.

Results

O3 exposure during the 70–90 days and 0–90 days preceding semen sample collection was significantly associated with an increased risk of low semen quality, with ORs of 1.020 (95% CI 1.003 to 1.039) and 1.056 (95% CI 1.008 to 1.108), respectively. Additionally, O3 exposure during the 0–90-days period showed a significant positive association with abnormal sperm concentration. A non-linear relationship between O3 exposure and sperm concentration was also observed. Notably, O3 exposure during the 0–9 days before semen collection was inversely associated with the risk of low semen quality. Subgroup analyses across age, lifestyle factors and socioeconomic strata revealed no significant effect modifications.

Conclusion

This study found that O3 exposure during the 70–90 days and 0–90 days before sampling was associated with reduced semen quality in men with unhealthy behaviours and low income.

Culturally sensitive stress management strategies for parents of preterm infants in the NICU: a systematic review of qualitative evidence protocol

Por: Chen · Y.-C. · Chang · M.-Y. · Wu · T.-Y. — Febrero 19th 2026 at 12:57
Introduction

Parenting a preterm infant in the neonatal intensive care units (NICUs) is a profoundly stressful experience, shaped by clinical uncertainty, physical separation and emotional vulnerability. Although stress management strategies—such as counselling, peer support and psychoeducation—are commonly available in NICU settings, little is known about how parents experience these forms of support when they are intended to be culturally sensitive or delivered within diverse cultural contexts. Cultural values, beliefs and practices shape how parents interpret stress and engage with support, highlighting the need to synthesise qualitative evidence on parents’ lived experiences of culturally sensitive stress management strategies during NICU hospitalisation.

Methods and analysis

This systematic review of qualitative evidence will be conducted in accordance with the Joanna Briggs Institute (JBI) methodology. A comprehensive search will be undertaken across six databases: MEDLINE, CINAHL, Scopus, Web of Science, PsycINFO and Airiti Library. This review will include qualitative studies that examine parents’ experiences, perceptions and meaning-making in relation to stress management strategies that are explicitly culturally sensitive or situated within identifiable cultural contexts in NICU settings. Studies published in English or Chinese between 2014 and 2024 will be eligible. Two reviewers will independently screen studies, assess methodological quality using the JBI critical appraisal checklist and extract data using the standardised JBI data extraction tool. Meta-aggregation will be used to synthesise findings, and the ConQual approach will be applied to assess confidence in the synthesised outputs.

Ethics and dissemination

This systematic review of qualitative evidence will synthesise data from previously published studies and does not require formal ethical approval. The review will be conducted and reported in accordance with the JBI methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systematic reviews. Findings will be disseminated through publication in a peer-reviewed journal and presentations at national and international conferences on neonatal care, nursing and family-centred healthcare. Target audiences include NICU clinicians, hospital administrators, educators and policymakers interested in integrating culturally responsive approaches into stress management and family support practices.

Efficacy and neural mechanisms of a vibrotactile-enhanced, brain-controlled soft robotic glove for upper limb rehabilitation after stroke: a multicentre randomised controlled trial protocol

Por: Catherine Chan · K. L. · Yan · C. · Wang · X. · Huang · S. · Dai · W. · Luo · Y. · Cheng · Y. · Xu · B. · Zhang · W. · Shen · Y. — Febrero 18th 2026 at 14:51
Introduction

Soft robotic gloves (SRGs) integrated with brain-computer interfaces (BCIs) have demonstrated potential in facilitating motor recovery after stroke by enabling active, intention-driven rehabilitation. Emerging evidence suggests that incorporating vibrotactile stimulation (VTS) into SRG-BCI systems may further enhance sensorimotor feedback. The objective of this study is to evaluate the therapeutic efficacy and underlying neural mechanisms of BCI-driven, intention-based glove activation compared with automated glove-assisted training, with VTS applied identically in both groups.

Methods and analysis

This multicentre, single-blind, randomised controlled trial will involve 48 post-stroke patients within 1 week to 3 months after stroke onset, with stratification by time since stroke during randomisation. Participants will be randomly assigned to either the BCI-SRG group (n=24) or SRG group (n=24). Both groups will receive identical VTS. Patients in the BCI-SRG group will actively initiate movements of the SRG through motor imagery, while those in the SRG group will receive automated glove-assisted training without BCI control. The intervention will be administered 5 days per week for 4 weeks. The primary outcome measure is the Fugl-Meyer Assessment of Upper Extremity. Secondary outcome measures include Wolf Motor Function Test, International Classification of Functioning, Disability and Health Generic Set, Barthel Index, Modified Ashworth Scale, Semmes-Weinstein Monofilament Test, as well as event-related spectral perturbation and event-related desynchronisation. All assessments will be conducted at both baseline and post-intervention.

Ethics and dissemination

Ethics approval of this study protocol has been obtained from the Ethics Committee of the First Affiliated Hospital with Nanjing Medical University (2025-SR-508). The findings will be disseminated through peer-reviewed journals, conference presentations and communication with scientific, professional and general public audiences.
