Journal articleLasala A, Fiorentino MC, Bandini A, et al., 2026, , Biomedical Signal Processing and Control, Vol: 120, ISSN: 1746-8094
Intraoperative ultrasound (iUS) is increasingly used in neurosurgery to monitor tumour margins during resection. The adoption of iUS is still limited by low image quality, noise, and heterogeneous echogenicity, which makes surgeons’ interpretation of surgical margins challenging. While deep learning can aid automatic margin delineation, the lack of annotated datasets limits the development of robust methods. To address this challenge, we propose a two-step generative framework based on latent diffusion models that consist of (i) an unconditional tumour-mask generator that learns geometric features of real tumours, and (ii) a conditional iUS image generator that synthesizes realistic iUS images by using the generated tumour masks as a prior. Morphological fidelity is assessed through tailored quantitative and qualitative metrics. The performance of automatic tumour margin segmentation algorithms is evaluated through data augmentation experiments to determine whether the inclusion of synthetic data can improve segmentation performance. Compared to state-of-the-art conditional generative models, including diffusion-based approaches (ControlNet) and generative adversarial networks (Pix2Pix), the proposed framework achieves superior qualitative and quantitative performance in representing tumoural and non-tumoural tissue. Performance evaluated using a 5-fold cross-validation protocol yields statistically significant improvements in morphological fidelity (Dice Similarity Coefficient: 0.851; Hausdorff Distance: 16.21). The analysis shows that introducing synthetic data significantly improves boundary delineation performance using nn-UNet, reducing the average Hausdorff Distance from 33.97 to 30.72 in the test set. These results indicate that the proposed framework helps mitigate the scarcity of annotated iUS data by providing realistic samples to support training in neurosurgical image segmentation.

Soft robotics offer biocompatibility, dexterity, and safe tissue interaction in surgery, providing potential alternatives to conventional tools such as colonoscopes. However, their nonlinear behaviour demands closed-loop control with structure-compatible feedback. This work presents a scalable 3D shape-sensing method based on Electrical Impedance Tomography (EIT), unifying actuation and sensing of a hydraulically actuated soft robot within a neural network framework. A soft continuum manipulator (14.6 mm in diameter) with saline-pressurised chambers and embedded kirigami-inspired FPCs was evaluated in free motion and ex vivo porcine colon trials. A multilayer perceptron (MLP) predicted the full 3D shape, achieving tip RMSEs of 0.46, 0.20, and 0.40 mm (x, y, z) in free motion, and 1.96, 0.86, and 0.89 mm in ex vivo. This letter marks the first ex vivo validation of EIT-based shape sensing in soft endoscopy and demonstrating its potential for closed-loop surgical control.

Private Health Insurance (PHI) in Gulf Cooperation Council (GCC) countries has experienced rapid growth over the past two decades, driven by demographic and economic changes. Although various analyses at the country level have been reported, no study has reviewed PHI systems in the GCC through a methodological approach. We provide a conceptual framework to review, describe and document the development of PHI in the GCC, based on literature from the scoping review. As of December 2023, all GCC countries have laws in place or have promulgated laws establishing mandatory PHI schemes. Most of these schemes are designed for expatriate populations residing in these countries, but there is a trend to extend them to nationals working in the private sector. The health system context plays a role in how PHI emerged and is designed in terms of role, eligibility, and coverage. PHI markets in the region are concentrated and dominated by local companies with performance levels that could be further improved. These markets are maturing and subject to more robust technical and prudential regulations as governments seek to enhance competition. Governments in the region must ensure the sustainable growth of these schemes and a more strategic alignment with health system objectives. Lessons learned from more mature markets are critical for future developments.

Label-free classification of breast cancer subtypes in ex vivo human tissues using Raman spectroscopy and machine learning
, Scientific Reports, ISSN: 2045-2322Breast conserving surgery (BCS) aims to excise breast tumors whilst preserving breast-related quality of life, but is complicated by the challenge of accurately identifying the margin between healthy and cancerous tissue. Raman spectroscopy (RS) has been shown to distinguish between normal breast tissue and breast cancer. Thus, this study aimed to further evaluate the diagnostic performance of RS in ex vivo breast tissue subtype classification via investigation of signals from healthy tissues and three breast cancer subtypes (invasive ductal carcinoma, IDC; invasive lobular carcinoma, ILC; and ductal carcinoma in situ, DCIS). A total of 80 tissue samples (46 normal and 34 cancerous) from 71 individuals were measured using a confocal Raman microscope. Spectral signatures wereinvestigated, and supervised classification was performed for both two-class (healthy vs. cancer) and four-class (healthy vs. IDC vs. ILC vs. DCIS) classification tasks. RS successfully differentiated cancerous from normal breast tissue (97.84% sensitivity, 97.18% specificity). For four-class classification, RS achieved in-class sensitivity ranging from 83-96% and specificity from 93-99%. These findings demonstrate that RS can accurately distinguish normal from cancerous tissue and capture clinically relevant differences among histological including invasive and pre-invasive disease, supporting its promise for intraoperative tissue characterization during BCS.

Social health-our ability to access and maintain meaningful human relationships-is recognized as a critical determinant of population health and climate change resilience, yet it is poorly integrated into climate change policy and research. This narrative Review synthesizes interdisciplinary evidence of the bidirectional and nuanced relationship between climate change and social health: climate change disrupts key social conditions (including housing stability and community cohesion), while widespread social disconnection limits our collective capacity to address the climate crisis. We unpack how social health can function as both a climate vulnerability and a lever for climate action. We present a new conceptual framework, describing the pathways through which social health and climate outcomes interact. Finally, we highlight existing evidence gaps and opportunities for public policy development and call for climate and health governance to centre social health as a key pillar of resilience in a changing world.

Understanding how language barriers in the paediatric emergency care setting influences safety of care delivery: a scoping review
, Emergency Medicine Journal, ISSN: 1472-0205Background: Communication in a family’s primary language can support safe care. Vital steps within the care delivery process are contingent upon successful communication, including reporting symptoms, clinical decision-making, informed consent, discharge communication, and follow-up coordination. The importance of effective information exchange is particularly pronounced in paediatric emergency care, and complex interactions may arise as parents or carers advocate on behalf of children. This scoping review aimed to identify and map existing research indicating where along the care journey communication-related risks for safety lie during paediatric emergency care and what strategies exist to mitigate them. Methods: We searched MEDLINE, Embase, CINAHL, Scopus, Web of Science, and Cochrane Library for studies which examined the influence of language barriers on patient safety in paediatric emergency care, as well as studies that evaluated interventions. Bibliographic database searches were executed on 18/12/2024; retrieved records were independently screened by two authors at title and abstract level followed by full text level. Data on study objectives, population characteristics, study design, and their key findings were extracted. Results: 1578 articles were identified, of which 33 were included and mapped according to (i) studies reporting safety risks linked to language barriers in paediatric emergency care (n = 24) and (ii) existing interventions designed to mitigate these risks (n = 9). Studies highlighted that language barriers can influence safety at multiple stages of the emergency care pathway, with discharge most frequently reported as a point of risk for paediatric patient safety. Interventions focused primarily on usage, uptake, and documentation of professional interpreter services.Conclusion: Addressing misunderstandings around follow-up and home-care advice during medical safety netting are priority areas for intervention. Future research should

IMPORTANCE: Climate change is associated with increasing mental health morbidity and mortality. However, an umbrella review to classify and quantify the global evidence on climate-related and nature-based mental health interventions is lacking. OBJECTIVE: To assess associations of climate-related and nature-based mental health interventions with mental health outcomes. DATA SOURCES: PubMed, PsycINFO, Web of Science, and Cochrane databases were searched from inception to November 17, 2024. STUDY SELECTION: Systematic reviews with meta-analyses (SRMAs) with controlled climate-related or nature-based mental health interventions and mental health outcomes were included. DATA EXTRACTION AND SYNTHESIS: Standardized mean differences (SMDs; intervention vs control) and 95% CIs were synthesized, evidence was stratified according to the level of credibility, and associations were assessed using meta-regression. MAIN OUTCOMES AND MEASURES: Outcomes were mental disorders, psychiatric symptoms, and positive mental health. RESULTS: Twenty-eight SRMAs were included that examined 344 studies and 91 associations between psychosocial or nature-based interventions and outcomes. Of the 91 associations, 10 (11%) had a moderate credibility of evidence and 81 (89%) had low or very low credibility. Psychosocial interventions addressing climatic impact drivers were associated with very low credibility, based on limited data. Nature-based interventions were associated with reductions in tension (SMD, -0.87; 95% CI, -1.31 to -0.43), fatigue (SMD, -0.80; 95% CI, -1.16 to -0.44), confusion (SMD, -0.65; 95% CI, -1.12 to -0.19), and negative affect (SMD, -0.51; 95% CI, -0.85 to -0.16), as well as increases in positive affect (SMD, 0.98; 95% CI, 0.65 to 1.30), vigor (SMD, 0.83; 95% CI, 0.37 to 1.28), and well-being (SMD, 0.40; 95% CI, 0.07 to 0.73), with moderate credibility of evidence and not addressing climatic impact drivers. Older participants and study locations with lower tree cover, better

X-ray phase-contrast tomography can efficiently image brain tissue at subcellular resolution. However, current sample preparation methods are not optimized to exploit the full potential of X-ray contrast mechanisms. Here we propose to replace interstitial material by air to enhance X-ray phase contrast of the ultrastructural features. Critical point drying (CPD) of heavy-metal-stained mouse brain tissue produced samples with preserved ultrastructure, a nanofoam-like material that remains compatible with follow-up conventional resin embedding. Using two synchrotron-based setups, namely, a high-throughput microtomography beamline and a nanoscale holographic tomography beamline, we found that CPD samples consistently showed 2-4× stronger phase-shift signal than samples embedded in resin. CPD offers a versatile route for preparing tissue for subcellular and ultrastructural-resolution X-ray imaging. It retains structural detail while improving signal, and is compatible with follow-up protocols involving femtosecond laser milling or electron microscopy, paving the path for biological tissue imaging beyond the mm3 scale.

Background: There is a dearth of studies examining the dietary intakes of parents from low- and middle-income countries, which are foundational for understanding the household-level double burden of malnutrition (DBM). Objectives: To assess the energy and nutrient intakes (carbohydrates, protein, fat, vitamin A, folate, zinc, and iron) of mother–father dyads from rural and urban households in Ghana using a wearable camera, an objective measure of dietary intake, not subject to self-reporting errors. Methods: In this cross-sectional study, purposive convenience sampling was used to recruit 60 households with a mother, father, and a child younger than 5 y and/or an adolescent from 1 rural and 1 urban community in Ghana. Both parents wore the Automatic Ingestion Monitor 2 (AIM-2) over 2 weekdays and 1 weekend day. Dietary intake was analyzed using custom AIM Annotation Software. Household characteristics were collected via questionnaire, and body mass index (kg/m<sup>2</sup>) was calculated from measured height and weight. Results: No differences in mean energy, macronutrient, or micronutrient intakes were observed between mothers and fathers within either area of residence. Dyad-level analyses showed that in rural households, mothers had higher caloric (P = 0.001), vitamin A (P = 0.048), and zinc intakes (P = 0.001) than fathers, who had higher iron intakes (P < 0.001) than mothers. In urban households, mothers had higher caloric (P = 0.006) and zinc intakes (P < 0.001) than fathers who had higher iron intakes (P < 0.001) than mothers. The prevalence of overweight/obesity was higher among mothers than fathers in both urban (70% versus 40%, P = 0.020) and rural (67% versus 30%, P = 0.005) households. Conclusions: The coexistence of overweight/obesity and low iron intakes among mothers highlights a unique presentation of the DBM at the household level. The AIM-2 shows promise for addressing limitations of traditional dietary assessment methods
