Motivational interviewing (MI) is gaining traction in veterinary medicine as an evidence-based approach for engaging clients in conversations that strengthen their intrinsic motivation to change behaviours that affect the welfare of animals in their care. While MI has a substantial and well-established evidence base across human healthcare and related fields, the veterinary evidence base remains small and is currently limited by study design challenges, inconsistent fidelity measurement, and outcome measures that rarely extend beyond short-term changes in communication behaviour. Existing methodological guidance addresses treatment integrity and theoretical mechanisms but does not provide an integrated framework for designing robust studies across the range of questions relevant to veterinary practice. This paper addresses that gap by providing practical methodological guidance for researchers designing MI studies in veterinary clinical settings. A novel conceptual model of the MI implementation pathway, mapping the journey from practitioner awareness through training and delivery to client outcomes, is used to organise key research questions that need to be answered in veterinary contexts. Guidance is then provided on selecting appropriate study designs, measuring fidelity and outcomes, estimating sample size, and managing the practical and ethical challenges specific to veterinary clinical settings, alongside minimum reporting standards to support more rigorous and reproducible MI research.

Background: Mental health disorders (MHDs) are an important concern among biomedical students, but estimates vary depending on whether studies assess confirmed diagnoses, perceived problems or current symptoms. This study assessed the presence of self-reported MHD history, operationalised as a heterogeneous combined outcome that included either a confirmed MHD diagnosis or a subjective perception of having or having had an MHD without official confirmation, and examined its associations with self-reported coping behaviours, resilience, study-related exhaustion and disengagement symptoms and healthy lifestyle adherence. Methods: A cross-sectional online survey was conducted among students from Medicine, Dental Medicine and Pharmacy programmes. Of 936 eligible students, 520 completed the survey (55.6%). The survey assessed self-reported MHD history and coping behaviours, while standardised questionnaires measured resilience, exhaustion and disengagement symptoms and healthy lifestyle adherence. Analyses included descriptive statistics, group comparisons, Spearman correlations, false-discovery-rate correction for exploratory coping-behaviour analyses and age- and gender-adjusted logistic regression. Results: Overall, 159 students (30.6%) had self-reported MHD history present, including 32 (6.2%) with a confirmed diagnosis and 127 (24.4%) with a subjectively perceived MHD without official confirmation. Exhaustion/disengagement scores negatively correlated with resilience and lifestyle scores, while resilience positively correlated with lifestyle scores (all p < 0.001). In adjusted logistic regression, higher resilience (OR = 0.539, 95% CI = 0.389–0.747, p < 0.001) and lifestyle scores (OR = 0.951, 95% CI = 0.929–0.974, p < 0.001) were associated with lower odds of self-reported MHD history being present. Conclusions: Self-reported MHD history was common among respondents and was associated with lower resilience, poorer lifestyle adherence and higher study-related exhaustion and disengagement symptoms. Because the outcome was heterogeneous and the design was cross-sectional, findings should be interpreted as associations rather than clinically verified prevalence estimates or causal effects.

Veterinary medicine fundamentally revolves around working with people to positively influence how they care for their animals. Veterinarians have traditionally used directive advice-giving when providing clients with recommendations, which can inadvertently push clients further away from change despite good intentions by evoking resistance and leaving the underlying motivational and contextual barriers to change unaddressed. Motivational interviewing (MI), a collaborative communication approach originally developed for addiction counselling, has been widely adapted across many fields because of its proven effectiveness in strengthening intrinsic motivation to change. MI was first applied in veterinary medicine approximately a decade ago with a small but growing evidence base. This review introduces the theoretical foundations of MI, how it can be applied within different types of clinical consultations, as well as the challenges of developing and sustaining competency in practice and ethical implications specific to the veterinarian–client–animal relationship, including the proxy motivation problem where clients bear the costs of behaviour change for benefits experienced primarily by their animal. This review then critically appraises the veterinary MI literature, which has largely focused on communication training outcomes with limited research on the downstream effects on client behaviour or animal welfare, highlighting important research gaps to promote an increased uptake of MI in clinical practice.

Equine sports medicine is increasingly oriented toward objective, field-based monitoring systems that support both performance optimization and welfare assessment. In this context, smartphone-based technologies have emerged as accessible tools capable of integrating data acquisition, processing, and interpretation within a single platform. This narrative review aims to examine the role of smartphones in equine sports medicine, focusing on their function as standalone sensing devices and as gateways for wearable and external sensor systems. The analysis is based on a structured synthesis of current literature addressing technological foundations, including embedded sensors, connectivity architectures, and artificial intelligence-driven data processing, as well as their clinical applications across locomotor, cardiovascular, respiratory, behavioural, and thermoregulatory domains. Evidence indicates that smartphone-based systems improve the feasibility of longitudinal monitoring and facilitate real-time decision-making in field conditions, while enhancing communication between veterinarians, trainers, and owners. However, their performance remains influenced by acquisition conditions, system variability, and algorithmic constraints, requiring careful validation and contextual interpretation. In addition, challenges related to data governance, privacy, and ethical use remain insufficiently addressed. Overall, smartphone-based technologies represent enabling tools that support a transition toward more integrated, data-driven, and welfare-oriented management of the equine athlete, while highlighting the need for standardisation and regulatory development.

Background/Objectives: The trainer–doctor model (TDM) is a participatory paradigm in which the physician acts as a mentor and educator. Effective health communication and patient engagement are key determinants of treatment adherence and health outcomes. Based on this conceptual framework, the present study aimed to assess preferences for the Trainer–Doctor Model among dental practitioners and patients, examine the influence of demographic variables, and provide a preliminary psychometric evaluation of the TDM questionnaire in accordance with the COSMIN (COnsensus-based Standards for the selection of health Measurement Instruments) criteria. Methods: A cross-sectional survey was conducted in Romania between May 2023 and April 2024. The study included dental practitioners recruited during scientific dental conferences and patients recruited from a private dental practice in Alba Iulia, Romania. Eligible participants were adults aged 18 years or older who provided written informed consent and completed the data protection requirements. Individuals younger than 18 years of age or those who did not provide complete informed consent were excluded. Participants completed a 12-item Likert-type questionnaire assessing preferences toward the Trainer–Doctor Model. Results: Both groups showed high TDM preference (practitioners: 43.93 ± 5.56; patients: 44.77 ± 4.84; p = 0.195); 71–76% of responses were high-preference (≥4). Cronbach’s α with reverse-scored items was 0.752/0.651. EFA (KMO = 0.740; Bartlett’s p < 0.001) identified a 3-factor structure, explaining 51.3% of the variance. Patients scored significantly higher on items A (p = 0.002), B (p = 0.022), and F (p = 0.005). Conclusions: Both groups demonstrate a strong, consistent preference for TDM across demographics. The preliminary psychometric evaluation indicates acceptable internal consistency and structural validity; however, further validation, including Delphi-based content validation and confirmatory factor analysis, is required.

Background: Type II workplace violence by patients, relatives, or visitors is an occupational health and patient-safety concern in primary care. Cranston Ridge Medical Clinic (CRMC), a single urban family medicine and walk-in primary care clinic in Calgary, Alberta, plans to implement a universal, risk-informed workplace-safety bundle that is based on observable behaviour, situational risk, and documented safety concerns rather than demographic profiling. Methods: This article describes a single-site internal quality improvement and workplace-safety evaluation protocol. The comparison is CRMC usual practice during the pre-implementation baseline period; there is no concurrent external control group. The planned evaluation will use aggregate, de-identified operational data from a 12-month pre-implementation baseline, a four-week implementation period, and 12 months of post-implementation monitoring. All clinic staff will receive workplace-safety training as part of routine implementation. No staff, patients, or visitors will be recruited as research participants, and the evaluation will not use individual-level staff survey, interview, or focus-group data. Patient/visitor information will be used only as aggregate operational monitoring data when needed to assess safety, access, patient flow, and complaints. Intervention and analysis: The bundle includes worksite analysis, staff training, a brief arrival safety screen, a response algorithm, standardized reporting, monthly safety huddles, and post-incident support. The primary metric will be the Type II workplace-violence incident rate per 1000 clinic visits. Planned analyses include run charts, pre–post rate ratios, and Poisson or negative binomial segmented regression if monthly counts are sufficient. Implementation learning will be summarized from routine training records, safety-huddle summaries, post-incident debrief themes, and other aggregate de-identified operational indicators. Expected contribution: The protocol contributes a transparent, equity-sensitive, and operationally feasible model for balancing staff safety with patient access in primary care. Full article

Background/Objectives: Anshen Bunao Oral Liquid (ABOL) is a traditional medicinal formula comprising Cornu Cervi Pantotrichum, Radix Polygoni Multiflori Preparata and other ingredients. It replenishes essence, nourishes qi and blood, and soothes the spirit. It is used in clinical practice to treat neurasthenia and insomnia (emotion-related symptoms), and its key component, glycyrrhizin, exhibits anxiolytic properties. This aligns with the holistic approach of traditional Chinese medicine (TCM) to regulating neuropsychiatric disorders. The aim of this study is to evaluate the anxiolytic efficacy of ABOL in rats with anxiety induced by chronic restraint stress (CRS), and to clarify its mechanism by focusing on modulation of the gut–brain axis (microbiota and metabolism). Methods: Sprague-Dawley rats underwent three hours of restraint per day for 28 days to induce anxiety. ABOL was administered intragastrically in three doses. Anxiety-like behaviours were assessed using OFT, EPM and SPT. Serum, tissue and faecal samples were analysed using ELISA, histopathology, immunohistochemistry, non-targeted metabolomics, 16S rRNA sequencing and RT-qPCR. Results: CRS induced anxiety-like behaviours, impaired weight gain and perturbed the balance of neurotransmitters (decreasing 5-HT, GABA, NE and DA, while increasing CORT), inducing inflammation/oxidative stress, hippocampal neuronal injury, intestinal barrier dysfunction and gut microbiota/metabolic dysregulation. ABOL effectively reversed these abnormalities by restoring the balance of neurotransmitters and the HPA axis, suppressing inflammation and oxidation, protecting neurons and the intestinal barrier, remodelling the gut microbiota (enriching Akkermansia and balancing Firmicutes/Bacteroidota) and regulating sphingolipid and glycerophospholipid pathways. The interaction between the gut microbiota and metabolites may contribute to this pharmacological effect. Conclusions: ABOL exerts anxiolytic effects by modulating the gut–brain axis at multiple targets, involving microbiota remodelling, regulation of lipid metabolism and improvement of pathology. This validates its ethnopharmacological value, linking traditional Chinese medicine to the development of modern anxiolytics. Full article

Background: The growing demand for safe and effective phytopharmaceuticals underscores the importance of studying regionally available medicinal plants. Acorus calamus L. and Calendula officinalis L., widely distributed in the Republic of Kazakhstan, are promising sources of biologically active compounds with significant pharmacological potential. However, the combined use of their CO₂ extracts remains insufficiently characterised, particularly regarding possible synergistic interactions. Therefore, the development of new dosage forms and their comprehensive pharmacological and toxicological evaluation is a priority in modern pharmaceutical research. Methods: Concentrated extracts from Acorus calamus rhizomes and Calendula officinalis flowers were obtained using precritical CO₂ extraction. Safety was assessed through acute and chronic toxicity studies in laboratory animals according to standard non-clinical guidelines. Animals received graded doses of the extracts and developed formulations (‘Exkair’ tablets and ‘Zerp-Ak-Broncho’ granules). Clinical condition, mortality, body weight, and behaviour were monitored. Biochemical, haematological, and histopathological analyses were performed. Antitussive activity was evaluated in vivo by measuring oedema inhibition relative to reference drugs. Results: The CO₂ extracts and formulations demonstrated low toxicity and good tolerability, with no mortality or significant adverse effects observed even at high doses. Biochemical and haematological parameters remained within physiological ranges, and histopathological examination revealed no structural alterations in internal organs. Both ‘Exkair’ and ‘Zerp-Ak-Broncho’ exhibited pronounced antitussive activity, confirmed by significant suppression of oedema. This effect is likely associated with the synergistic action of flavonoids, terpenoids, and phenolic compounds. Conclusions: The findings indicate that CO₂ extracts of Acorus calamus L. and Calendula officinalis L., as well as the developed formulations, possess a favourable safety profile and significant antitussive activity. These results support their further development as phytotherapeutic agents in Kazakhstan. Full article

The creation of innovative systems that are able to combine diagnosis and therapy is a crucial opportunity in nuclear medicine. Here, we propose a methodological and multiscale approach for the development of a theranostic platform based on AuNRs functionalized with radiopharmaceuticals. AuNRs offer a versatile and effective system due to their unique physicochemical properties and the possibility of surface functionalization with targeting molecules. Within this framework, key challenges include the functionalization of AuNRs to target the cell nucleus, the loading of AuNRs with radiopharmaceuticals, and the investigation of Auger electron emission from AuNRs under gamma irradiation. Multiscale modelling is employed to describe the behaviour of the system within the cellular environment and to predict potential radiobiological enhancement effects, including synergistic interactions between functionalized AuNRs and radiopharmaceutical agents such as ^99mTc-sestaMIBI. The experimental activity includes gamma irradiation studies, along with the structural and physical characterization of nanomaterials and in vitro biological investigations on T98G cells, to evaluate cytotoxicity and metabolic alterations, with the aim of assessing the potential synergistic effects of the combined system.

This review aimed to evaluate the effectiveness and feasibility of non-pharmacological interventions to reduce anxiety and agitation and improve observable wellbeing and patient engagement for people with dementia in acute hospital environments. The global increase in dementia has resulted in a substantial number of acute hospital beds occupied by people with dementia. Hospitalisation can exacerbate behavioural and psychosocial symptoms of dementia (BPSD) including anxiety and agitation, which negatively affects patient experience, safety and care. Clinical guidance recommends non-pharmacological interventions as a first-line tactic to manage BPSD. However, evidence for the effectiveness and feasibility of these interventions remains fragmented in such pressured environments. A systematic search of seven databases was conducted for studies published in the last ten years (2015–25), following the PRISMA guidelines. Fourteen studies met the eligibility criteria and included a total of 749 people with dementia. Studies used mixed interventions; music, music therapy and person-centred care highly featured and most studies reported reductions in observable BPSD during or immediately after interventions. Secondary benefits included wellbeing, reduced psychotropic medicine use, length of hospitalisation and high staff and patient acceptability. There was limited evidence for sustained effects beyond intervention. This review supports the feasibility and effectiveness of non-pharmacological interventions in acute hospitals to support dementia-inclusive, person-centred care. Full article

Background/Objectives: Siblings of children with the life-limiting disease Metachromatic Leukodystrophy (MLD) are growing up witnessing rapid disease progression and death, affecting development and psychological wellbeing. Family-centred palliative care should include sibling support, but research on sibling needs is scarce. This semi-structured interview study aims to describe parents’ perceptions of siblings’ behavioural adaptation, emotional reactions, and support needs. Methods: Seven parents recruited from a national resource centre for rare disorders participated in semi-structured interviews that were audiotaped and transcribed. Content analysis was used to identify recurrent themes. Results: Siblings were described as more mature, patient, caring, appreciative, and sociable than other children due to life with the ill child. Expressions of love and concern, fear, sadness and sorrow, anger, and hope were described. Parents described how sibling support implies strengthening close family relations and providing resources at home, external support, and information. Conclusion: This study shows that sibling support involves all instances surrounding the family and ill child, and that a family-centred, trauma-sensitive approach is needed. Full article

The Morus genus comprises several tree species whose fruits are used in human nutrition, while the leaves and roots are used in traditional medicine. The aim of this study was to highlight the antioxidant, cholinesterase inhibitory, and neuroprotective effects of hydroalcoholic extracts from Morus alba (MAE) and Morus nigra (MNE) leaves. RP-UHPLC-PDA analysis of extracts revealed the presence of polyphenols in higher quantities in MNE extract compared to MAE. Both extracts demonstrated antioxidant properties in the hydroxyl radical scavenging and lipid peroxidation inhibition assays. MNE exhibited a superior antioxidant capacity compared to MAE; the IC₅₀ values for the inhibition of plasma lipid oxidation assay were 25.31 ± 2.54 µg/mL for MNE and 29.85 ± 0.97 µg/mL for MAE. Both extracts showed cholinesterase inhibitory activity. The IC₅₀ values for acetylcholinesterase inhibition were 24.34 ± 0.86 µg/mL for MNE and 46.87 ± 2.16 µg/mL for MAE. The inhibitory potency of MNE was comparable to that of galantamine, which was used as standard. Both extracts reversed, in a dose-dependent manner, the scopolamine-induced cognitive impairment and behavioural alterations in scopolamine-treated zebrafish (Danio rerio) as evaluated by the Y-maze test, novel tank diving test, and novel object recognition test.

Organoselenium chemistry has undergone remarkable development over the past five decades, evolving from its initial association with high toxicity into a field with pivotal contributions to materials science, organic synthesis, catalysis, and Medicinal Chemistry. Among the diverse biological activities displayed by organoselenium compounds, their redox behaviour is particularly compelling, as many of these molecules act as efficient mimetics of the antioxidant enzyme glutathione peroxidase (GPx). In this work, we investigated the GPx-like activity of a series of N,N′-diaryl selenoureas toward the depletion of H₂O₂ and cumene hydroperoxide (CumOOH) as model ROS. Their reactivity was correlated with the electronic nature of the aryl substituents using a Hammett-type analysis, revealing a strong dependence of the reaction rate on remote electronic perturbations within the aromatic ring. Combined UV and NMR studies provided mechanistic evidence supporting a catalytic cycle in which selenoureas, operating at sub-stoichiometric loadings (1 mol%) and using a thiol as a cofactor-like molecule, can be used to efficiently scavenge ROS with half-lives of only a few minutes (~10–60 min). Furthermore, these selenoureas exhibited potent antiproliferative activity across several human solid tumour cell lines. Overall, these results offer mechanistic insight into the ROS-eliminating pathways of selenoureas and highlight their potential as chemopreventive or anticancer agents. Full article

Background: Interstitial cystitis (IC) is a debilitating lower urinary tract condition characterised by chronic inflammation of the bladder. As the aetiology remains unknown, current treatments are symptomatic, aiming to reduce inflammation and pain. Cannabidiol (CBD), the most common cannabinoid in industrial Cannabis sativa (hemp), is one of the most important pharmacologically active cannabinoids used in medicine due to its anti-inflammatory and antioxidant effects without psychoactive properties. While other cannabinoids have shown beneficial effects in animal models of IC, the impact of CBD on the urinary bladder and overall animal well-being has not been elucidated. Methods: Using a cyclophosphamide (CYP)-induced mouse model of IC, we investigated the effects of intraperitoneally administered CBD on bladder structure, function, inflammation, and animal behaviour. A multimodal approach was applied, including light and electron microscopy, immunolabeling, qPCR, transepithelial electrical resistance (TEER) measurements, behavioural testing, and monitoring of animals. Results: CBD treatment promoted the restoration of damaged urothelial structure and improved the integrity of the blood–urine barrier. Additionally, CBD exerted an anti-inflammatory effect, reducing oedema and infiltration of inflammatory cells in the bladder wall with chronic cystitis. Finally, the increased burrowing activity of CBD-treated mice suggests a benefit of CBD on overall well-being. Conclusions: Our findings suggest that CBD has a beneficial effect on the inflamed urinary bladder and could potentially serve as an adjunct treatment for patients with IC in the future.

Canine Cognitive Dysfunction Syndrome (CCDS) is a progressive neurodegenerative disease affecting older dogs that shares many pathological mechanisms with human Alzheimer’s disease (AD). Although it is common in geriatric dogs, CCDS is often underdiagnosed in veterinary medicine. Both CCDS and AD involve a gradual decline in cognitive functions such as memory, learning and executive abilities. From a pathological perspective, dogs with CCDS show brain changes similar to those seen in AD, including cerebral atrophy, loss of neurons and accumulation of amyloid-beta plaques. CCDS is diagnosed by exclusion, meaning that other medical or neurological conditions that could cause similar behavioural signs must first be ruled out. Clinical evaluation mainly relies on structured questionnaires completed by owners. Magnetic resonance imaging is used to confirm cerebral atrophy and, at the same time, to exclude other brain disorders, such as cerebrovascular accidents and neoplasia. Current research focuses on identifying fluid biomarkers, such as amyloid-beta, neurofilament light chain and glial fibrillary acidic protein, to support an early and objective diagnosis. The most effective management combines pharmacological therapy, targeted nutrition and non-pharmacological strategies, including environmental enrichment and behavioural support. Early intervention, ideally during mild cognitive impairment, is crucial to slow disease progression and maintain quality of life. Full article
