ABSTRACT

BACKGROUND: Extreme cephalic conformation has been theorised to be associated with compromised health in rabbits. However, recognition and assessment of such phenotypes remain largely subjective. This study aimed to develop and validate a visual, semi-quantitative system for head shape phenotype in rabbits.

METHODS: Images of rabbits were collected and visually analysed for comparative phenotypic patterns, with a 1-5 grading scale subsequently created. Initial validation of the system was conducted via an online pilot survey across 24 experienced individuals. Interobserver agreement across scores was calculated to assess the reliability of the system.

RESULTS: The proposed system yielded strong, ‘almost perfect’ and statistically significant interobserver agreement for cephalic assessment (W = 0.908, 95% bias-corrected and accelerated [BCa] confidence interval [CI]: 0.858-0.950; α = 0.880, 95% CI: 0.875-0.885), with largely positive feedback from veterinary professionals.

LIMITATIONS: Further development and validation of the system are required for complete, reliable assessment of all rabbits, particularly those with longer fur. Wider participation in the validation of this method from across the profession is also necessary.

CONCLUSION: This system has the potential to enhance conformational assessment in rabbits. Implementation of the system in clinical practice may help to promote awareness of potential conformation-associated health risks and catalyse discussions regarding responsible ownership. The system may also support further studies into the precise influence of conformation on disease risk.

ABSTRACT

Background:The COVID-19 pandemic disrupted work environments worldwide, increasing productivity loss through absenteeism and presenteeism. Identifying key associated factors is essential for informing workplace health strategies during public health crises. Methods/Project: A systematic review and meta-analysis were conducted following PRISMA guidelines, using comprehensive searches of seven electronic databases from inception through January 2024. Studies were systematically selected based on predefined eligibility criteria, and 24 studies examining individual and work-related factors associated with work productivity loss were included. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal tools. Correlation coefficients were synthesized using a random-effects meta-analysis of correlations in STATA 17.0, and heterogeneity was evaluated using the I² statistic and Cochran’s Q test. Findings: Twenty-one factors were analyzed. Job stress, fear of COVID-19, mental health problems, job insecurity, turnover intention, exhaustion, and job demands exhibited moderate positive correlations with productivity loss during the COVID-19 pandemic. Fear of COVID-19 and mental health problems showed relatively large positive correlations with presenteeism. General health status was the factor most strongly associated with absenteeism, exhibiting a moderate negative correlation. Conclusions/Application to Practice: These findings identify key individual and work-related determinants of productivity loss during pandemics. The results support the development of targeted workplace health promotion, mental health support, and preparedness strategies to mitigate productivity loss during future public health emergencies.

ABSTRACT

OBJECTIVE: To evaluate the association of admission neutrophil-to-lymphocyte ratio (NLR) with functional outcomes, intracranial hemorrhage (ICH), and mortality in patients with acute ischemic stroke (AIS).

METHODS: We searched PubMed, Scopus, Web of Science, Cochrane CENTRAL, and Embase from inception until December 17, 2024. Studies examining admission NLR as a predictor for functional outcomes, ICH, and mortality in AIS patients were included. A meta-analysis was performed using pooled odds ratios (ORs) with 95% confidence intervals (CIs). Subgroup analyses were conducted based on treatment modality, time of measurement, hemorrhage type, and ethnicity. Heterogeneity was assessed using I² statistics, and publication bias was evaluated using Egger’s test.

RESULTS: Sixty observational studies (33,049 patients), including 59 cohort studies and one cross-sectional study, were included. Higher admission NLR was significantly associated with unfavorable functional outcomes (OR: 1.10, 95% CI: [1.07, 1.14]), ICH (OR: 1.06, 95% CI: [1.03, 1.09]), and mortality (OR: 1.06, 95% CI: [1.04, 1.08]). Subgroup analysis indicated that NLR was associated with poor outcomes in AIS patients receiving mechanical thrombectomy and intravenous thrombolysis.

CONCLUSION: Admission NLR is significantly associated with unfavorable functional outcomes, ICH, and mortality in AIS patients. Its predictive value remained evident in the MT and Asian subgroups; however, the association with unfavorable functional outcomes was not significant in the non-Asian subgroup, and the association with mortality in the IVT subgroup was also not significant. Given its accessibility and cost-effectiveness, NLR holds promise as a routine biomarker for stroke prognosis.

ABSTRACT

Primary membranous nephropathy (pMN) is a principal cause of nephrotic syndrome in adults. The identification of the M-type phospholipase A2 receptor (PLA2R) antigen has significantly advanced non-invasive management; however, the precise clinical relationship between circulating antibody titers and intrarenal antigen deposition continues to be debated. This single-center retrospective study sought to analyze the correlation between clinicopathological parameters, serum anti-PLA2R levels, and glomerular PLA2R tissue expression in pMN. A specific focus was placed on evaluating the diagnostic utility of tissue staining in seronegative patients. A cohort of 49 adult pMN patients, diagnosed via renal biopsy between 2018 and 2025, was evaluated. Serum anti-PLA2R antibodies were quantified using ELISA, while glomerular PLA2R expression and staining intensity (graded 0 to +3) were assessed via immunohistochemistry (IHC) on paraffin-embedded sections. The results demonstrated a notable discordance: the overall serum antibody positivity rate was 49.0%, yet tissue PLA2R expression was detected in 100% of the cohort, encompassing all seronegative cases. A statistically significant difference was observed in the distribution of tissue PLA2R staining intensity based on serum PLA2R status (p=0.002). Conversely, no statistically significant correlation was found between circulating antibody titers and baseline renal function or proteinuria markers (p>0.05). In conclusion, these findings indicate that negative serology does not preclude tissue PLA2R positivity, potentially attributable to mechanisms such as the “kidney-as-a-sink” phenomenon or persistent immunological footprints. This investigation underscores that serum and tissue PLA2R serve as complementary, rather than mutually exclusive, markers. Consequently, renal biopsy with supplementary IHC staining remains a crucial and clinically valuable diagnostic tool, particularly in seronegative cases.

ABSTRACT

OBJECTIVE: Small peripheral pulmonary lesions are nowadays preferably diagnosed by navigation bronchoscopy, yet reported diagnostic yields vary across different techniques. Shape-sensing robotic-assisted bronchoscopy (ssRAB), now also available in Europe, combines real-time shape sensing with an actively steerable catheter, potentially improving diagnostic yield. We aimed to compare ssRAB combined with cone-beam computed tomography (CBCT) imaging (ssRAB+CBCT) against our current standard, CBCT-based navigation bronchoscopy (CBCT-NB) alone.

METHODS: We conducted a single-centre, propensity score-matched analysis comparing patients undergoing ssRAB+CBCT with patients undergoing CBCT-NB for the diagnosis of small peripheral pulmonary lesions. Matching was performed on known lesion characteristics influencing yield. Primary outcome was strict diagnostic yield. Secondary outcomes included diagnostic accuracy at follow-up, safety and procedure-related metrics.

RESULTS: A total of 131 patients with 183 biopsied lesions were included in the ssRAB+CBCT arm. Median lesion size was 12 mm (interquartile range 8-18 mm). Propensity score matching with lesions from our reference CBCT-NB cohort was successful in 150 out of 183 lesions. The diagnostic yield at the lesion level was 73% for the ssRAB+CBCT arm and 70% for the CBCT-NB arm; the mean difference of 3.3% (95% CI -6.9-13.5%) was not statistically significant (p=0.521). The diagnostic yield at the patient level for the ssRAB+CBCT arm was 82%.

CONCLUSION: ssRAB+CBCT has a diagnostic yield similar to that of our highly optimised CBCT-NB programme, and was below the study’s powering assumption of a 15% increase in diagnostic yield. There was a suggestion of benefit in small nodules with a negative bronchus sign. The unique features of ssRAB mean that it holds promise, but larger studies are warranted to clarify its position and optimal case selection, compared with other navigation bronchoscopy technologies, its clinical impact and its cost-effectiveness.

ABSTRACT

INTRODUCTION: Prolonged waiting times significantly limited access to our respiratory physiotherapy service for cough control therapy. In response, we developed a virtual physiotherapy group intervention for individuals with chronic cough (ViP-Cough) to improve accessibility. This article describes the uptake and potential benefits of this novel approach.

METHODS: A service evaluation was carried out utilising a retrospective observational cohort study design involving patients with chronic cough referred to a single-centre respiratory physiotherapy service. All referrals were assessed by a specialist physiotherapist and offered access to ViP-Cough, a single-session virtual group intervention comprising: 1) education and lifestyle advice; 2) cough control strategies; and 3) breathing pattern retraining and vocal hygiene. Patients completed outcome measures at baseline and 4 weeks post-intervention, including numerical rating scales (NRS) for cough severity, frequency and impact on daily activities (0-10; higher scores indicating worse outcomes), and confidence in self-management (0-10; higher scores indicating better outcomes). Descriptive statistics and paired samples t-tests were used for analysis.

RESULTS: Of the 194 patients referred (median age 61 years; 79% female), 70% reported cough duration >5 years. Of those screened, 155 (80%) opted in; 116 attended, and 106 completed all assessments. Significant improvements were observed in cough severity (mean difference (95% CI) -1.26 (-0.82- -1.70), p<0.001), frequency (-1.19 (-0.79- -1.60), p<0.001), impact on daily life (-1.16 (-0.23- -1.61), p<0.001) and confidence in self-management (+2.16 (1.64-2.68), p<0.001).

CONCLUSION: ViP-Cough is a promising, scalable and low-cost approach to delivering nonpharmacological cough therapy. These preliminary findings support further evaluation in a randomised controlled trial.

ABSTRACT

BACKGROUND: Pleural mesothelioma (PM) is a fatal asbestos-related cancer with a poor and often uncertain prognosis. This study validates the histological proliferation marker Ki67 and evaluates whether its integration into the two-tier tumour grading system can improve prognostication in epithelioid PM.

METHODS: Patients with epithelioid PM were recruited from two longitudinal cohort studies from 2010-2023. Diagnostic biopsies were analysed by three pulmonary pathologists. Cox regression determined the relationship between covariables and outcomes. Pearson correlation assessed the association between Ki67 and two-tier grade. A prognostic model combining Ki67 and tumour grade was internally validated using bootstrapping.

RESULTS: 98 patients were recruited. Ki67 was strongly predictive of overall survival (OS) and progression-free survival (PFS) and correlated with two-tier tumour grade. 30% was the optimal cut-off, with Ki67 more strongly predictive of OS (hazard ratio (HR) 2.37, 95% CI 1.51-3.71) and PFS (HR 2.09, 1.35-3.23) than two-tier grade (HR 1.83, 1.13-2.97 and HR 1.70, 1.08-2.66, respectively). Combining Ki67 and two-tier grade improved prediction of OS and PFS compared with two-tier grade alone. Ki67 stratified patients within each tumour grade, with median survival in the lowest risk group (low Ki67, low grade) of 660.5 days (IQR 329-1297) and 300 days (IQR 124-366) in the highest risk group (high Ki67, high grade).

CONCLUSION: Ki67 is a valid surrogate for tumour grade with an optimal cut-off at 30%. Integrating Ki67 into the two-tier grading system enhances prognostic accuracy, improves outcome prediction and would reduce uncertainty for patients and clinicians.

ABSTRACT

Effectiveness of health systems is achieved through universal coverage, while efficiency is reached by minimizing the cost of delivery. This study presents a novel analysis for designing national health systems, considering workforce, equipment, global costs and accessibility in different geographical contexts. Designed to be a medium- and long-term strategic planning tool, our model offers a practical solution by assessing projected health infrastructure and resources and evaluates health requirements using data from the OECD, the World Bank, OpenStreetMap, and national health statistics. Applied to Brazil, Finland, and France, the analysis is in line with UN Sustainable Development Goal 3.8 and the WHO’s Human Resources for Health strategy. The findings suggest that regions with dispersed populations, such as central-western Brazil and northern Finland, would benefit from small hospitals, clinics and health centers. Brazil should hire more health professionals, purchase more radiotherapy equipment and invest $7.95 billion in logistics to reduce patient travel times, particularly for the 1,222 municipalities most affected by low accessibility. Finland would benefit from additional hospital beds and CT scanners, while France could benefit from a more centralized health care model, with municipalities providing all levels of care. France should also invest more in nursing staff and mammography equipment.

ABSTRACT

Animal production in extensive livestock systems faces significant health and welfare challenges due to variable environments, diverse climatic conditions, and practical constraints that limit close animal monitoring. By “extensive livestock systems”, we refer to production systems characterized by large herd sizes, open-range grazing, and limited direct animal supervision, typical of beef cattle, sheep, and goat farming in rangeland environments. Conventional approaches, including visual inspection and periodic veterinary assessment, often provide incomplete and delayed insights into animal health status, limiting timely intervention for infectious and metabolic diseases. Recent advances in wearable sensors, imaging technologies, genomic testing, omics profiling, and environmental monitoring offer new opportunities for continuous, data-driven surveillance of livestock. However, when applied in isolation, these modalities capture only partial aspects of the complex biological and environmental processes that influence animal health and disease progression. Multimodal monitoring integrates these diverse data streams to provide a more comprehensive and dynamic representation of animal health. This enables earlier detection of disease risk, improved welfare outcomes, and enhanced support for veterinary and on-farm decision-making. Ultimately, such integration empowers farmers to achieve earlier and more precise interventions, reduce veterinary costs, and improve overall animal welfare and productivity in extensive systems. This review synthesizes current approaches to multimodal monitoring in extensive livestock systems, explores data integration strategies, and evaluates key challenges for practical implementation, including cost, scalability, and data interoperability. We conclude by outlining future research directions that prioritize feasibility, affordability, and farmer-centered design to facilitate real-world adoption.

ABSTRACT

INTRODUCTION: This pilot study aimed to compare sonographic findings at thoracic sites used to detect pneumothorax in canine cadavers.

METHODS: Intubated frozen-thawed cadavers without pre-existing sonographic evidence of pneumothorax were included. Control, unilateral and bilateral pneumothorax groups were created, with the latter induced by infusion of air (3 mL/kg) under ultrasound guidance. Four blinded sonographers (two experts and two novices) evaluated positive-pressure-ventilated (PPV) cadavers placed in sternal recumbency. Lung sliding and B-lines were assessed at the chest tube site (CTS) and caudo-dorsal border (CDB), while the abnormal abdominal curtain sign (AACS) was evaluated along the abdominal curtain sign (ACS). When absence of lung sliding was noted, operators searched for a lung-point (LP). Presence or absence of pneumothorax was recorded for the CTS, CDB, AACS, combined CTS + LP, and CDB + AACS + LP (Modified PLUS). Post-study right and left horizontal beam radiography was used as the reference standard to quantify pneumothorax volume by a board-certified radiologist. Results were analyzed by Fisher’s exact test with a statistical significance set at p < 0.05.

RESULTS: Mild pneumothorax was present in 10/16 hemithoraces, scant pneumothorax in 3/16, and no pneumothorax in 3/16. Combined accuracy, sensitivity, and specificity of all operators was 22% (9-40), 4% (0-20), 100% (54-100) for both CTS and CTS + LP; 53% (35-71), 42% (23-63), 100% (54-100) for CDB; 31% (16-50), 15% (4-35), 100% (54-100) for AACS; and 56% (38-74), 46% (27-67), 100%(54-100) for Modified PLUS, respectively. There was a significant difference in identification of pneumothorax between the CTS and CDB (p = 0.00027), and CTS and Modified PLUS (p = 0.0012) and between CTS + LP and Modified PLUS for all operator comparisons (p = 0.00012).

DISCUSSION: The site assessed (CDB vs. CTS) for lung sliding and the sonographic signs (AACS, lung sliding) evaluated with different POCUS protocols can influence the accuracy of diagnosing pneumothorax in PPV canine cadavers placed in sternal recumbency.
