Heterogeneity in job preferences among young physicians in Chinese tertiary hospitals: a discrete choice experiment

Por: Li · Q. · Zhang · Q. · Han · Y.
Background

Physicians’ preferences for financial and non-financial incentives significantly influence their job satisfaction and career choices. A comprehensive understanding of these preferences can aid in the optimisation of incentive policies. While prior studies have examined these preferences using discrete choice experiments (DCEs), the effects of intrinsic motivations, such as altruism and job satisfaction, on incentive responsiveness remain poorly understood. Understanding this heterogeneity is essential for designing incentive policies that are effective and tailored to the healthcare context in China. This study aimed to assess how physicians’ altruism and job satisfaction shape their preferences for financial and non-financial incentives.

Methods

This study employed a DCE methodology and surveyed 886 physicians from urban tertiary hospitals. The DCE design was based on a comprehensive literature review and focus group interviews, assessing physicians’ preferences regarding attributes such as work environment, workload, career development opportunities and career identity. Mixed logit models were used to estimate the willingness to pay for each attribute and analyse heterogeneity across subgroups based on levels of altruism and job satisfaction.

Results

Financial incentives were the most important factor for physicians, followed by attributes such as work atmosphere and workload. On average, physicians expressed a willingness to sacrifice 4859.035 ¥ for an improved work atmosphere and 4335.008 ¥ in exchange for reduced workload. Subgroup analysis showed that physicians with low- and medium-altruism prioritised improvements related to working conditions, while those with high-altruism placed greater emphasis on intrinsic career development and career identity. Furthermore, physicians reporting low-job satisfaction demonstrated heightened sensitivity to both financial and non-financial incentives, whereas those with high-job satisfaction showed weaker preference for financial incentives and greater preference for improvements in work atmosphere (β=1.002) and work environment (β=0.876).

Conclusion

The findings highlight the need to align incentive policies with physicians’ intrinsic motivations and current job satisfaction. Financial incentives remain a key driver of job preferences. Non-financial factors, including improvements in the work atmosphere, work environment, workload, career development and professional identity, also play an important role in supporting physicians’ job satisfaction and retention. Considering differences in altruism and job satisfaction can help healthcare institutions and policymakers develop more targeted and context-specific incentive strategies.

Safety and efficacy of the Atalante exoskeleton in the rehabilitation of French patients with amyotrophic lateral sclerosis: a prospective, monocentric, open, uncontrolled, interventional protocol, EXALS

Por: Trad · G. · Lenglet · T. · Ledoux · I. · Querin · G. · Blancho · S. · Marchand-Pauvert · V. · Hogrel · J.-Y. · Pradat · P.-F.
Introduction

Robotic rehabilitation on locomotion is a new approach in amyotrophic lateral sclerosis (ALS) and previous studies showed its feasibility. In this study, we aim to evaluate safety, patient’s experience and efficacy of a gait training programme with the Atalante exoskeleton, compared with usual care, on walking ability, functional capacity and other symptoms associated with ALS.

Methods and analysis

EXALS is a monocentric, prospective, interventional, open trial. 20 slowly progressing patients with gait deficits will be recruited. The study is conducted in three phases, each lasting 6 weeks, following the ABA procedure. Phase B represents the intervention phase, during which patients practise their gait training at a rhythm of three sessions/week, as an add-on to usual care. In the two phases A, patients receive usual care with no additional treatment. An evaluation is planned before, in the middle and at the end of each phase. The primary outcome of the study is safety and tolerability of the Atalante exoskeleton. Secondary outcomes include: participants’ subjective impact and experience, attitude and motivation, efficacy and interactivity of the exoskeleton, walking ability, functional capacity, spasticity, balance, postural stability, lower limb muscle strength, quality of life, pain, fatigue, anxiety and depression. Statistical analyses will include descriptive methods for all variables and adverse events. Quantitative outcomes are analysed using repeated-measures ANOVA (analysis of variance) across the seven visits, with post hoc tests applied when appropriate. Nominal outcomes are evaluated using Cochran’s Q test with McNemar pairwise comparisons when significant. Associations between variables are examined using Spearman correlation coefficients. Missing data will be replaced using linear interpolation, and sensitivity analyses will be planned. Qualitative interview data are analysed using thematic analysis.

Ethics and dissemination

This study was approved by the French ethics committee CPP Nord-Ouest I (no. 23.02378.000201). Participant data are anonymised and securely stored in the laboratory’s database, accessible only to the research team. Results will be disseminated through peer-reviewed journals and conferences.

Barriers and facilitators to implementing the living guideline development framework in oncology: a mixed methods study

Por: Ismaila · N. · Harvey · B. E. · Einhaus · K. · Mbuagbaw · L. · Ma · J. · Thabane · L.
Objective

To explore stakeholder experiences with implementing the living guideline (LG) development framework in oncology, and to identify barriers, facilitators and solutions to support its uptake and sustainability.

Design

An exploratory sequential mixed methods design was used, beginning with qualitative semi-structured interviews with guideline development stakeholders, analysed thematically; and followed by a cross-sectional survey to quantitatively rate the importance of factors identified in phase one.

Setting

National and international oncology guideline development programmes using the LG development framework.

Participants

Stakeholders involved in LG development, including expert panel co-chairs, panel members, patient representatives, methodologists and administrative staff.

Results

Nine stakeholders participated in qualitative interviews, and 45 completed the survey. Most participants were male (5/9:56% qualitative; 26/45:58% quantitative) and based in the US (7/9:78% and 29/45:64%, respectively). Overall, the results from both the qualitative and quantitative strand revealed seven themes (34 subthemes) as barriers and six themes (21 subthemes) as facilitators. Additionally, 9 themes were proposed as solutions. The most frequently reported barriers included evidence timeliness, interpretation and publication delays. Prominent facilitators included effective management, resource optimisation and panel engagement. Participants strongly endorsed investment in artificial intelligence enhanced tools to improve the speed and efficiency of evidence acquisition and review.

Conclusion

While the LG framework provides strong methodological guidance, its practical application presents notable challenges, particularly in resource demands and implementation logistics. Successful adoption requires adequate infrastructure, expertise and oversight. These findings highlight critical considerations for developers aiming to implement sustainable LG models in oncology and beyond.

Knowledge, attitude and practice towards glaucoma among ophthalmic inpatients: a cross-sectional study in Hunan, China

Por: Zhao · Y. · Wu · P. · Liao · L. · Zhang · J. · Zhou · D. · Sun · W. · Dong · F. · Ye · C. · Duan · X.
Objectives

Glaucoma is an optic neuropathy caused by the gradual degeneration of retinal ganglion cells. This study aimed to investigate the knowledge, attitude and practice (KAP) towards glaucoma among ophthalmic inpatients.

Design

A web-based questionnaire.

Setting

Local hospital.

Participants

Ophthalmic inpatients (n=1238).

Primary and secondary outcome measures

The primary outcome was the patients’ KAP.

Results

Multivariable logistic regression analysis showed that rural residence (OR=0.488, 95% CI 0.313 to 0.762, p=0.002), college education or above (OR=4.996, 95% CI 2.942 to 8.483, p

Conclusions

Ophthalmic inpatients might have moderate knowledge and attitude, but a proactive practice towards glaucoma. A history of glaucoma, previous glaucoma surgery, education level, residency and alcohol consumption were potentially associated with knowledge and attitudes towards glaucoma among ophthalmic inpatients.

Implementing multi-component intervention to reduce antibiotic prescribing in primary care of rural China: a qualitative process evaluation of the trial

Por: Zhang · T. · Shen · X. · Chai · J. · Liu · R. · Wang · D. · Yardley · L. · Lambert · H. · Cabral · C.
Objectives

The overuse of antibiotics for respiratory tract infections in primary healthcare in rural China is a particular challenge and is highly related to antibiotic resistance. Our research team designed a multi-component intervention focusing predominantly on health practitioners to reduce antibiotic prescriptions in rural communities of China. The effects of the intervention were evaluated through a randomised controlled trial. This study was conducted alongside the trial to develop a contextualised understanding of the implementation of the intervention and related influencing factors.

Design

Qualitative process study nested in a randomised controlled trial, including observation and semi-structured interviews.

Setting

Primary healthcare in rural China.

Participants

27 health practitioners from township health centres assigned to the intervention arm.

Intervention

A complex intervention to reduce antibiotic prescriptions in rural communities of China, which includes the following components: training for health practitioners, a public letter of commitment, patient leaflets, a decision support system and a peer support group.

Primary and secondary outcome measures

Not applicable.

Analysis

Data were analysed using thematic analysis.

Results

The overall multi-component intervention was described as useful in reducing antibiotic prescribing, with a particularly high acceptance and use of patient leaflets and the public letter of commitment among health practitioners. There were mixed views on the decision support system and peer support group. Practitioners reported usability-related barriers to using the decision support system during consultations. Practitioners did not understand the role or benefits of the peer support group and found it difficult to initiate group discussions, due to the lack of any existing clinical team at the primary care level.

Conclusions

The multi-component intervention appears to be acceptable and useful in primary healthcare in rural China. Successful implementation requires a comprehensive understanding of the contextual characteristics of the setting. Interventions to reduce antibiotic prescribing in China in the future could consider wider stakeholders including patients, retail pharmacies and health authorities.

Intradialytic kinetics of cardiac biomarkers during high-flux haemodialysis and postdilution haemodiafiltration: study protocol for a randomised crossover trial

Por: Drivsholm · C. L. · Nygaard · L. · Glerup · R. I. · Birnum · A. T. S. · Jensen · J. D. · Svensson · M.
Introduction

Cardiovascular disease (CVD) is the leading cause of mortality in patients undergoing chronic haemodialysis (HD). However, relatively few data exist regarding the influence of dialysis treatment on cardiac biomarkers such as high-sensitivity cardiac troponin I and T (hs-cTnI and hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), complicating their interpretation in the diagnosis of acute coronary syndrome and heart failure. This study aims to investigate the intradialytic kinetics of hs-cTnT, hs-cTnI and NT-proBNP, during HD and haemodiafiltration (HDF), in patients treated with chronic HD.

Methods and analysis

Single-centre, randomised, open-label, crossover study, comparing high-flux HD (FX 100 dialyser) and postdilution HDF (FX 1000 dialyser), regarding their potential clearance of hs-cTnI, hs-cTnT and NT-proBNP, in 24 stable patients treated with in-centre HD without acute CVD. The study will investigate changes in concentrations during and after high-flux HD and postdilution HDF and calculate reduction ratios, dialyser clearance and clearance by adsorption to the membrane of the selected cardiac biomarkers. Blood samples will be collected at baseline, after 10, 30, 60, 120, 180 and 240 min of dialysis and 30 min postdialysis. After 120 min of dialysis, dialysate will also be collected from the dialyser outlet line. The primary outcome is change from baseline in concentrations of hs-cTnI, hs-cTnT and NT-proBNP during high-flux HD and postdilution HDF.

Ethics and dissemination

The study has been approved by the North Denmark Region Committee on Health Research Ethics (N-20240016). Results will be published in an international peer-reviewed journal and disseminated at national and international research meetings.

Residual factors associated with poor oral hygiene among Japanese kindergarten children: a cross-sectional study

Por: Oiwa · D. · Oura · A. · Hayashi · T. · Nakata · K. · Nakata · M. · Koyama · M. · Himuro · N. · Ohnishi · H.
Objectives

To identify behavioural and household factors associated with poor oral hygiene among Japanese kindergarten children in a population with high health awareness, using the Debris Index-Simplified (DI-S) as a clinical proxy for early oral hygiene deterioration.

Design

Cross-sectional study.

Setting

Seven kindergartens in Sapporo city, Japan.

Participants

Of the 1229 kindergarten children invited, 871 provided parental consent (consent rate: 70.9%). Among them, 675 children aged 1–6 years who completed both the questionnaire and oral examination (completion rate: 54.9%). Most post-consent losses were due to logistical and staffing constraints. Children were stratified into ≤3 year and ≥4 year academic classes.

Primary and secondary outcome measures

The primary outcome was oral hygiene status based on the DI-S scores (categorised as good (DI-S=0) or poor (DI-S>0). The secondary outcome was the presence of dental caries, defined as decayed, missing and filled primary teeth: dmft≥1. Multivariable logistic regression was used to estimate associations between poor oral hygiene and behavioural and household factors.

Results

Among the 675 children, 168 children (24.9%) exhibited poor oral hygiene (DI-S>0) and 89 children (13.2%) had dental caries (dmft≥1). In multivariable analysis adjusted for demographic, dental and dietary variables, poor oral hygiene was significantly associated with being from a multiple-child household (OR 1.67, 95% CI 1.16 to 2.42) and irregular juice consumption (OR 1.60, 95% CI 1.07 to 2.38). Age-stratified analysis revealed that these associations persisted among those in the ≥4 year class, with additional significance for infrequent tooth brushing (

Conclusions

In a high health awareness Japanese preschool population, poor oral hygiene was independently associated with household composition and juice consumption, rather than traditional dental behaviours. These findings suggest the need to broaden preventive strategies beyond routine dental guidance to include family structure and dietary patterns, particularly in low-prevalence settings. Differential associations between DI-S and caries experience emphasise the utility of early clinical indices in oral health promotion.

Por: Obodai · E. · Asante Ntim · N. A. · Duker · E. O. · Gberbi · E. · Antwi · C. N. · Mensah · J. Y. · Odame · D. · Boakye · J. D. · Bimpong · S. A. · Agbotse · G. D. · Odoom · N. · Adams · P. L. · Acquah · N. K. · Dickson · A. E. · Odoom · C. · Achempem · K. K. · Baffoe-Nyarko · I. · Egbi
Objective

To evaluate the performance of Ghana’s environmental surveillance (ES) system for poliovirus (PV) detection from 2018 to 2022 using standardised indicators developed by the WHO and the US Centers for Disease Control and Prevention.

Design

A retrospective performance evaluation using 10 key indicators benchmarked against global targets for PV surveillance.

Setting

Seven regions across Ghana, participating in the national ES programme implemented under the Global Polio Eradication Initiative.

Surveillance coverage

Wastewater sampling was conducted at designated ES sites, supported by field collection teams and laboratory personnel responsible for sample acquisition, processing and reporting of PV detection results.

Outcome measures

Detection rates of PV and non-polio enteroviruses (NPEVs), timeliness of sample collection and reporting, data quality and system stability.

Results

A total of 738 wastewater samples were collected. The system demonstrated high sensitivity, detecting circulating vaccine-derived PV type 2 in 51 (6.9%) of samples, Sabin PV types 1 and 3 in 61 (9.5%) and 114 (17.8%), respectively, and NPEVs in 491 (66.5%) of samples. Over 80% of samples met the recommended 21-day collection-to-reporting time frame. Data quality exceeded the ≥80% threshold, and workflows remained stable throughout the evaluation period.

Conclusions

Ghana’s ES system for PV was found to be flexible, stable and effective in generating high-quality data for early detection and public health response. These findings underscore the system’s critical role in supporting polio eradication efforts and highlight its potential as a model for surveillance in similar settings.

Traditional, integrative and complementary medicine use in the UK population: results of a nationally representative cross-sectional survey

Por: van der Werf · E. T. · Foley · H. · Carter · T. · Roberts · R. · Adams · J. · Steel · A.
Objectives

To describe the prevalence and characteristics of traditional, complementary and integrative medicine (TCIM) practice and product use by the population of the UK providing up-to-date data on the landscape of TCIM use in the UK.

Design, setting and participants

A cross-sectional online survey, administered using the Qualtrics platform, among adults (aged 18 years and over) residing in the UK (England, Wales, Scotland or Northern Ireland). Data were collected between May and October 2024. The 40-item instrument covered four domains: demographics, health status, use of health products and practices, and use of health services. Descriptive statistics were used to summarise survey responses, and ² tests were applied to assess associations between participant characteristics and TCIM use. Backwards stepwise logistic regression was conducted to identify predictors of TCIM use across four outcome categories (p≤0.05).

Results

The sample (n=1559) was broadly representative of the UK population. Prevalence of any TCIM use over a 12-month period was 65.9% with 19.1% consulting a TCIM practitioner and 63.3% using any TCIM product or practice. Bodywork therapists (massage therapists 9.4%, chiropractors 7.9%, yoga teachers 5.0%) and homeopaths (4.1%) were the most commonly consulted TCIM practitioners and Anthroposophic doctors were the least commonly consulted (2.1%). Among TCIM products, vitamin and mineral supplements were the most commonly used (37.3%) and relaxation or meditation practices were reported by 19.4% of respondents. TCIM users were more likely to be female, identify as Asian or Black, have a chronic disease diagnosis, report good health, possess private health insurance, have a higher education level, be employed (or seeking employment) and sometimes experience financial management difficulties.

Conclusions

There is substantial use of TCIM across the UK adult population and there is a need for more research on integrating TCIM into mainstream healthcare and the National Health Service. Clear strategies are necessary to enhance communication between TCIM and conventional healthcare providers, ensure patient safety and promote person-centred, coordinated models of care.

Global scoping review of key domains of patient-reported experience of care measures across life stages and healthcare technical areas

Objectives

Patient-reported experience measures (PREMs) are measures of patients’ perceptions of care they receive. PREMs are critical in developing and evaluating programmes that aim to improve patient healthcare experiences and quality of care (QoC) according to patient-defined needs. This review aims to map key domains of PREMs across distinct healthcare technical areas and life stages from globally available literature.

Design

A scoping review adapting Arksey and O’Malley’s framework and Joanna Briggs Institute’s guidelines for the conduct of scoping reviews.

Data sources

Google Scholar, PubMed, WHO, US Academy of Medicine and USAID Momentum.

Eligibility

PREMs literature from electronic repositories of grey and peer-reviewed publications, published in English historically up to September 2023.

Data extraction and analysis

Two lead reviewers with support from the technical working group co-created a review framework of healthcare technical areas, life stages and PREMs domains. We screened eligible articles, prioritising reviews except for technical areas with no reviews, where we then selected individual studies. We charted, analysed and synthesised data from 52 eligible articles.

Results

PREMs literature has recently increased, especially in low-income and middle-income countries (LMICs), although studies in high-income countries (HICs) dominate in proportion (n=38; 73.1%). Out of 52 eligible articles, technical areas with most publications were sexual and reproductive health (n=21; 40.4%) and general outpatient care (n=11; 21.2%). Studies in adulthood (n=24; 46.2%) and from pregnancy and birth to postnatal (n=16; 30.8%) were most represented. PREMs studies reported mostly on communication and rapport (n=33; 63.5%) and respect and dignity (n=42; 80.8%) domains. Nearly a quarter (n=12; 23.1%) of the articles included only validated tools; the rest included a combination of validated and unvalidated measures. Of the tools relating to life stages of babies, younger children and older adults, the majority (n=17; 94.4%) included patient proxies.

Conclusion

PREMs, as an important component of QoC measurement, are increasing across several healthcare technical areas and life stages with commonalities and notable distinctions in measurement domains and tools. Evidence on PREMs largely comes from HICs. Evidence on critical, yet sometimes overlooked domains, highlights key QoC implementation gaps. The adaptation and utilisation of PREMs in programmes, especially in LMICs and under-represented technical areas, present opportunities to close the QoC disparities in those settings. Strategic, concerted efforts towards the harmonisation of PREMs tools across multiple life course stages and technical areas are critically needed in high-level quality improvement efforts.

Bacterial community associated with the surface and inside of centipede forcipules: Identification and characterization

by Yasutaka Tanaka, Daiki Mizushima, Yoshimitsu Izawa, Tomohiro Matsumura, Chikara Yonekawa, Hirotomo Kato, Takashi Mato

Background

In tropical to subtropical regions, centipede bites may prompt medical attention, with manifestations largely reflecting venom-related discomfort, although infections, including rare fatal necrotizing soft tissue infection (NSTI), have been reported. However, no reports are available on the commensal bacteria on centipede forcipules.

Objectives

This study aimed to investigate bacterial species residing on and in centipede forcipules and their potential role in post-bite infections.

Methods

Nine Scolopendra mutilans, three Scolopendra japonica, and two Bothropolys rugosus were collected from three regions in Japan. The bacterial composition of their forcipules was analyzed using 16S ribosomal ribonucleic acid gene sequencing and microbiome analysis.

Findings

A diverse bacterial community was observed on the centipede forcipules. Among the NSTI-associated genera examined (Escherichia, Staphylococcus, and Streptococcus), only Staphylococcus was identified as a minor population.

Conclusion

This study provides the first evidence that some bacteria found on centipede forcipules have been previously isolated from centipede bite infections. The risk of infection from bacteria on centipede forcipules during a centipede bite appears low. However, the presence of diverse bacterial species emphasizes the importance of thoroughly cleaning centipede bite wounds to prevent secondary infection.

The mediating role of internal motivation on the relationship between ethical leadership and employee performance in hospitals in Northern Jordan

by Raya Al-Bataineh, Ameera Hayajneh

Objective

The study’s main aim is to investigate the influence of ethical leadership (EL) on employee performance (EP) through internal motivation (IM) from the perspectives of clinical and administrative employees working in hospitals in northern Jordan.

Method: Design

The study used a descriptive, correlational cross-sectional quantitative design.

Participants and setting

Data were collected from 330 clinical and administrative employees between February and March 2024 using convenience sampling from five hospitals—2 public, 2 private, and 1 teaching hospital—in different geographical areas in northern Jordan. The study hypotheses were tested using a hierarchical multiple linear regression.

Results

The study results revealed a statistically significant association between ethical leadership, internal motivation, and employee performance. Moreover, the results showed that internal motivation statistically mediates the relationship between ethical leadership and employee performance.

Conclusion

The current study’s findings can serve as an empirical basis for hospital decision-makers to plan and implement programs and/or establish or revise policies for the target population, improving employees’ performance, achieving desired outcomes, and ultimately providing better care for patients.

Safety and feasibility of one-stage neonatal approach for short-segment Hirschsprung’s disease

by Quynh Anh Tran, Hien Duy Pham, Dung Boi Ly, Minh Quang Ngo, Nhung Thi Nguyen, Liem Thanh Nguyen, Quang Thanh Nguyen

Background

Early definitive surgery for Hirschsprung disease (HD) in neonates is increasingly adopted to reduce preoperative morbidity and preserve long term bowel function. However, comparative data across minimally invasive approaches in neonates with short segment disease remain limited. This study compared outcomes of single incision laparoscopic assisted endorectal pull through (SILEP), conventional laparoscopic assisted endorectal pull through (CLEP), and complete transanal endorectal pull through (TERPT) for rectosigmoid HD.

Methods

We conducted a retrospective cohort study of 55 neonates who underwent one stage definitive surgery before 28 days of age at a high volume center between January 2019 and December 2021. The primary outcome was long term bowel function assessed using the Rintala Bowel Function Score (BFS) after a minimum of 4 years of follow up. Secondary outcomes included operative parameters, postoperative complications (Clavien Dindo classification), and cosmetic outcomes using the Manchester Scar Scale (MSS) in the laparoscopic groups.

Results

All patients successfully underwent surgery at a mean age of 22.4 ± 4.3 days. Operative time differed across approaches and was shorter for SILEP (53.8 ± 11.9 minutes) and TERPT (52.1 ± 18.3 minutes) than for CLEP (70.2 ± 22.5 minutes, p = 0.036). At follow up (mean 54.0 ± 7.7 months), the overall BFS was 17.5 ± 2.5 with no significant differences among groups (p = 0.32). MSS was numerically lower for SILEP than for CLEP (6.2 ± 1.1 vs 6.8 ± 1.9, p = 0.53). Complications were infrequent, with 14 minor and 7 major events, and there was no mortality or Clavien Dindo grade IV or V morbidity.

Conclusion

SILEP, CLEP, and TERPT are feasible one stage options for neonates with rectosigmoid HD, with comparable long term bowel function and low rates of major complications. SILEP and TERPT were associated with shorter operative times, and SILEP showed a trend toward improved cosmetic scores compared with CLEP. These findings support an individualized approach to technique selection based on intraoperative requirements and institutional expertise.

Association between mink coronavirus (MCoV), <i>Campylobacter</i> spp., and diarrhea in farmed mink <i>(Neogale vison)</i>

by Michelle Lauge Quaade, Mikael Leijon, Mikhayil Hakhverdyan, Thomas Bruun Rasmussen, Charlotte Kristiane Hjulsager, Lars Andresen, Karin Mundbjerg, Anne Sofie Vedsted Hammer

Diarrhea outbreaks significantly affect the health and growth of farmed mink, posing economic and welfare challenges. While various pathogens have been linked to mink diarrhea, the causes during the weaning period remain unclear. Sporadic associations of mink coronavirus (MCoV), Campylobacter, and gastrointestinal disease in mink have been suggested. This study investigates the occurrence and levels of MCoV and Campylobacter in fecal samples from Danish farm mink (Neogale vison) and their potential association with post-weaning anorexia diarrhea syndrome (PADS), growth-period diarrhea (GPD), or pre-weaning diarrhea (PWD). The focus of the study is on PADS, studied through two case-control setups where case farms had known problems with PADS and control farms without such problems. Animals were also diagnosed based on necropsy pathological findings. Seventeen MCoV genomes were determined from five Danish farms. This data facilitated the development of an MCoV RT-qPCR and was applied across three study groups. Results showed high prevalence of both MCoV and Campylobacter spp. in all groups. No link was found between MCoV presence or levels and PADS diagnosis on the individual level; however, farm-level analysis revealed that MCoV was 2.35 times more likely (95% CI 1.027; 5.056) on PADS case farms than controls. Mink with PWD exhibited higher MCoV levels compared to GPD cases, suggesting a role at this developmental stage. Phylogenetic analysis revealed diverse and farm-specific MCoV strains, with sequences from healthy controls forming a distinct subclade, hinting at strain-specific pathogenicity. Campylobacter spp. presence was not significantly associated with PADS, but higher levels were observed in mink with PADS versus those without (not tested for PWD). These findings highlight the importance of surveillance and rigorous hygiene practices on mink farms to address risks from MCoV and Campylobacter spp., calling for further research to clarify their roles in PADS and overall mink health.

Machine learning and network pharmacology identify keloid biomarkers (AMPH, TNFRSF9) and therapeutic targets (IL6, HAS2) for aloe-derived quercetin

by Congli Jia, Fu Yang, Yingchun Li

Objective

This study aimed to identify diagnostic biomarkers for keloid and explore potential therapeutic agents from traditional Chinese medicine (TCM) by integrating network pharmacology approaches. Specifically, we sought to uncover key molecular targets for Aloe vera and validate their roles in keloid pathogenesis.

Methods

We integrated keloid transcriptome datasets (GSE218007 and GSE237752) by merging GEO data, and identifying differentially expressed genes (DEGs). Functional enrichment analysis (GO, GSEA) and machine learning approaches were applied to select diagnostic biomarkers. Candidate genes were validated via Receiver Operating Characteristic (ROC) curves in training and independent cohorts (GSE44270). PPI networks and Cytohubba algorithms identified hub genes, while TCMSP-screened compounds from Aloe vera were docked with targets using molecular docking.

Results

91 Identified DEGs enriched in fibrosis-related pathways. Machine learning prioritized two diagnostic biomarkers: AMPH and TNFRSF9 (AUC > 0.85 in training/testing). PPI analysis revealed IL6 as a hub gene. Aloe vera-derived quercetin targeted HAS2 and IL6 (both P  Conclusion

AMPH and TNFRSF9 are promising diagnostic biomarkers for keloid, while quercetin from Aloe vera targets HAS2 and IL6, offering therapeutic potential. The dual role of IL6 underscores its centrality in keloid pathogenesis, connecting bioinformatics predictions with TCM pharmacology. This study provides a foundation for clinical prediction and targeted treatment strategies.

Artificial intelligence-based dairy cattle behavior recognition for estrus detection via ensemble fusion of two camera views

by Panawit Hanpinitsak, Tatpong Katanyukul, Norrawit Tonmitr, Chanon Suntra, Sora-at Tanusilp, Arthit Phuphaphud

Monitoring cattle behavior plays an important role in improving farm productivity, maintaining animal welfare, and supporting efficient management practices. This study presents a multi-view behavior recognition system that uses synchronized top-view and front-view CCTV footage, combined with deep learning techniques. The system includes four main components: cow identification, behavior classification, identity-behavior association using Intersection-over-Union (IoU), and a decision-level ensemble to combine information from both views. YOLOv8 models are applied separately to each camera angle to detect individual cows and classify six key behaviors: drinking, eating, standing, lying, riding, and chin resting, with the latter two being relevant for estrus detection. The system matches cow identities to their behaviors within each view and then integrates the results to produce a final activity label for each cow.

Impact of storage conditions on the stability and biological efficacy of <i>trans</i>-arachidin-1 and <i>trans</i>-arachidin-3

by Ploy Khongrungjarat, Chonnikan Tothong, Chanyanut Pankaew, Suchada Phimsen, Nopawit Khamto, Nutthamon Kijchalao, Warissara Wongkham, Piyathida Wongkham, Wipaporn Chuaymaung, Adsadayu Thonnondang, Apinun Limmongkon

Prenylated stilbenoids, particularly trans-arachidin-1 (Ara-1) and trans-arachidin-3 (Ara-3), have gained attention for their notable bioactivities and potential health-promoting properties. This study presents the first comprehensive investigation into the stability and biological efficacy of these compounds in both peanut hairy root culture crude extracts (PCE) and partially purified fractions derived from elicited peanut hairy root cultures. PCE stored at –20 °C and 4 °C maintained higher antioxidant capacity, total phenolic content compared to samples stored at room temperature. In cytotoxicity assays using SW480 colon cancer cells, the extract stored at –20 °C retained bioactivity with only minor changes in IC₅₀ values over three months, demonstrating superior stability under frozen conditions. Over a six-month period, partially purified fractions of Ara-1 and Ara-3 showed a time-dependent decline in compound content. However, Ara-3 maintained strong cytotoxicity against KKU-100 cholangiocarcinoma cells, while Ara-1 exhibited a significant loss in activity. These findings demonstrate that low-temperature storage, particularly at –20 °C, is crucial for preserving the chemical integrity and bioactivity of stilbenoid-rich extracts. The study underscores the importance of optimizing storage conditions to ensure consistent bioactivity, supporting the potential application of these compounds in the development of stable and effective pharmaceutical or nutraceutical products.

Supporting mental well-being of healthcare workers using a mobile app: A mixed-methods feasibility study

by Mehmet Yildirim, Timothy Carter, Holly Blake

Poor mental well-being is common among healthcare workers, affecting individual health, patient safety, and organisational performance. Mobile app-based self-care interventions are promising due to their accessibility, low cost, and ease of use. This study aimed to assess the feasibility of a self-monitoring mobile app called MYARKEO, to improve mental well-being among healthcare workers and healthcare trainees in the United Kingdom (UK). The study evaluated recruitment and retention rates, variability of key outcomes to inform a future randomised controlled trial (RCT), intervention engagement, barriers and facilitators to engagement, and potential refinements to the mobile app. A mixed-method feasibility RCT was conducted with two groups: an intervention group using MYARKEO to monitor mental well-being over 6 weeks, and a non-intervention control group. Data were collected at baseline and post-intervention and included the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), the Depression Anxiety and Stress Scale (DASS-21), and the mHealth App Usability Questionnaire (MAUQ). Qualitative data were collected through semi-structured interviews (n = 13) and analysed using thematic analysis. Forty-nine participants (32 workers, 17 trainees; aged 18–60+) were included in the trial, with a 20.5% dropout rate. Daily app usage averaged 64.5%. Participants frequently monitored mood, sleep, food, and exercise. Interviews identified themes of “Usefulness,” “Enablers of engagement,” “Barriers to engagement,” and “Suggested intervention improvements.” This study demonstrates the feasibility of using a mobile app to monitor and promote mental well-being among healthcare workers and trainees. While app engagement was promising, challenges were identified, highlighting the need for refinements to the app’s content, interface, and design for future trials.

Custom foot orthoses for chronic metatarsalgia: Study protocol for a participant- and assessor-blinded superiority randomized controlled trial

by Eléna Payen Schalkens, Maxime Acien, Andrée-Anne Marchand, Pier-Luc Isabelle, Jacques Abboud, Gabriel Moisan

Background

Chronic metatarsalgia (CM) causes significant pain and disability, affecting quality of life. Foot orthoses (FOs) including medially wedged designs with a metatarsal pad decrease excessive plantar pressure under the metatarsal heads, which is a suggested risk factor for developing CM. This FOs model may be effective in diminishing pain and improving function in these individuals. Thus, the objective of this trial will be to compare the effects of medially wedged FOs with a metatarsal pad and sham FOs on pain and foot function in individuals with CM.

Methods/design

This participant- and assessor-blinded superiority randomized controlled trial (RCT) with two parallel groups will be conducted in Trois-Rivières, Canada. Sixty-four participants with CM will be recruited from the Université du Québec à Trois-Rivières outpatient podiatry clinic and via social media invitations. They will be randomized into intervention (customized FOs) or control (sham FOs) groups and will be evaluated at baseline and after 6 and 12 weeks. The primary outcome will be: (1) mean pain during walking for the most painful foot during the past week. The secondary outcomes will be: (1) Foot Function Index, (2) Global rating of change and (3) the 5-level EQ-5D.

Discussion

Medially wedged FOs with a metatarsal pad are expected to provide a greater reduction in pain and improvement in foot function compared to sham FOs. This trial will help guide FOs prescription recommendations for managing foot pain in individuals with CM in the future.

Towards practical AI for agriculture: A self-supervised attention framework for Spinach leaf disease detection

by Nilavro Das Kabya, MD Shaifullah Sharafat, Rahimul Islam Emu, Mehrab Karim Opee, Riasat Khan

Malabar spinach is a nutrient-dense leafy vegetable widely cultivated and consumed in Bangladesh. Its productivity is often compromised by Alternaria leaf spot and straw mite infestations. This work proposes an efficient and interpretable deep learning framework for automatic Malabar spinach leaf disease classification. A curated dataset of Malabar spinach images collected from Habiganj Agricultural University and supplemented with public samples was categorized into three classes: Alternaria, straw mite, and healthy leaves. A lightweight SpinachCNN established a strong baseline, while Spinach-ResSENet, enhanced with squeeze-and-excitation modules, improved channel-wise attention and feature discrimination. A customized Vision Transformer (SpinachViT) and SwinV2-Base were further investigated to assess the benefits of transformer-based architectures under limited data. To mitigate annotation scarcity, we employed SimSiam-based self-supervised pretraining on unlabeled images, followed by supervised fine-tuning with cross-entropy or a hybrid objective combining cross-entropy and supervised contrastive loss. The best-performing domain-optimized model, SimSiam-CBAM-ResNet-50, incorporated Convolutional Block Attention Modules and achieved 97.31% test accuracy, 0.9983 macro ROC-AUC, and low calibration error, while maintaining robustness to Gaussian and salt-and-pepper noise. Although a SwinV2-Base benchmark pretrained on ImageNet-22k reached slightly higher accuracy (97.98%, 98.99% with test-time augmentation), its 86.9M parameters and reliance on large-scale pretraining reduce feasibility for edge deployment. In contrast, the SimSiam-CBAM model offers a more parameter-efficient and deployment-friendly solution for real-world agricultural applications. Model decisions are interpretable via Grad-CAM, Grad-CAM++, and LayerCAM, which consistently highlight biologically relevant lesion regions.
