ABSTRACT

INTRODUCTION: Animal-assisted therapies are increasingly applied in rehabilitation and complementary care, particularly in supporting mental and neurocognitive conditions. The targeted therapeutic use of songbirds and their vocalizations (ornithotherapy) represents a relatively novel approach that remains underrepresented in the international literature, especially regarding objectively measurable physiological outcomes.

OBJECTIVE: The aim of our study was to evaluate the effects of an ornithotherapy intervention on blood pressure and pulse rate in a residential institution caring for individuals with intellectual disabilities, compared to corresponding periods before and after the intervention.

METHOD: A retrospective analysis was conducted covering the period between 2022 and 2025. Documented blood pressure and pulse data of residents were analyzed. The intervention took place between October 17, 2023, and March 15, 2024, during which birdsong was played on weekdays for 10 minutes daily in communal areas. Data from the intervention period were compared with corresponding control periods.

RESULTS: Generalized Estimating Equation analyses showed consistent cardiovascular patterns across the three years. A statistically significant change was observed only in systolic blood pressure during the intervention year. Mean systolic blood pressure values in 2023 were significantly lower compared to 2022, with an estimated reduction of approximately 2-3 mmHg. No significant changes were found in diastolic blood pressure or pulse rate.

DISCUSSION: These findings suggest that auditory intervention may exert a modest but measurable effect on systolic blood pressure, while diastolic blood pressure and pulse remain unaffected.

CONCLUSION: Birdsong-based auditory stimulation appears to have a moderate and selective effect on systolic blood pressure. Ornithotherapy may represent a low-cost, easily applicable complementary approach in institutional care. Further prospective studies are warranted to better define its therapeutic potential.

ABSTRACT

AIM: To observe and describe the surgical wound care practices of nurses in a Sri Lankan tertiary care hospital.

DESIGN: A cross-sectional observational study.

METHODS: We observed surgical wound care practices of registered nurses (RNs) working in 13 general surgical wards of a 3000-bed tertiary care hospital in Sri Lanka. An observation tool developed based on clinical practice guidelines (CPGs) and a chart audit tool were used for data collection. Field notes were taken to describe contextual details. A convenience sample of RNs and a consecutive sample of adult, postoperative patients were recruited. Patients were included once, while nurses were observed on multiple occasions. Descriptive statistics were used, and field notes were added to contextualise the data.

RESULTS: We observed wound care episodes across 250 postoperative patients with 63 RNs. Nurses’ hand hygiene (HH) adherence was 58.4% (n = 146) before dressing changes and 43.2% (n = 108) after dressing changes. Wound care education was observed in only 22% (n = 55) of episodes. Documentation of wound care was noted only on 53 (21.2%) occasions. Field notes highlighted the lack of standard wound assessment and management protocols and resource constraints influencing the nurses’ adherence to CPGs on many occasions.

CONCLUSION: Our findings suggest that nurses’ adherence to CPGs was limited, and there are unwarranted variations in nurses’ surgical wound care practices. Unavailability of standard wound care protocols and resource constraints were also identified. These variations appear multifactorial, reflecting limitations in training, staffing, resources and the absence of standardised wound care protocols.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Targeted training programs should be conducted for nurses, and context-sensitive wound management protocols should be introduced.

IMPACT: As one of the first studies to describe nurses’ surgical wound care practices in a resource-limited country, these findings offer valuable insights into both practice and the contextual influences.

REPORTING METHOD: The Strengthening the Reporting of Observational Studies in Epidemiology guidelines.

PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

ABSTRACT

To identify, describe and critically appraise studies developing and/or validating models for predicting sight-threatening retinopathy of prematurity (ROP) in preterm infants undergoing screening in neonatal intensive care units. PubMed, Embase via Ovid, trial registers, and grey literature were searched from inception to 21 October 2025. Eligible studies included those that developed and/or validated prognostic models for sight-threatening ROP in screened preterm infants. Data extraction followed the CHARMS checklist. Reporting adhered to TRIPOD-SRMA and PRISMA guidelines. Model quality, risk of bias, and applicability were assessed using PROBAST+AI. The protocol is available on Open Science Framework (https://osf.io/dgc4y). Thirty-five unique prognostic models for sight-threatening ROP were identified from 30 development studies. Gestational age, birth weight, and postnatal weight gain were the most frequently reported predictors, followed by sex. Twenty-three models underwent at least one external validation (155 validations in total). Most development studies showed substantial methodological concerns related to study design, handling of missing data, lack of external validation, and inadequate reporting of performance measures. Studies assessing model performance (apparent, internal, or external) were also at high overall risk of bias due to design, analytical, and reporting shortcomings. Collectively, these limitations may reduce the generalizability and clinical applicability of existing models. Despite numerous ROP prediction models, methodological limitations and limited robust validation preclude widespread clinical adoption. Future research should prioritize development and prospective, multicentre validation across large, diverse cohorts, with emphasis on readily available and objectively measured predictors, alongside strict adherence to established methodological and reporting standards (TRIPOD-AI, PROBAST+AI) to ensure reliable, generalizable tools for optimizing ROP screening.

ABSTRACT

Colloidal suspensions exhibit diverse phases from fluid-like to solid-like, which are critical for numerous industrial applications. However, accurately identifying their phases remains a challenge, as they depend on a complex interplay of solid volume fraction, particle size distribution, and interparticle interactions. Near phase boundaries, subtle microstructural changes can induce drastic macroscopic property variations, yet these differences are often indistinguishable through conventional observation. To overcome these limitations and the high computational costs of long-time simulations, we propose a transformer-driven framework based on reference-based data embedding. Unlike standard point cloud models that directly embed positions, our approach utilizes particle stress information as the primary feature while using spatial coordinates solely as a reference to map interparticle relationships. This allows the transformer-driven model to effectively capture structural characteristics at both local and global scales. By training the model exclusively on unambiguous regions far from phase boundaries to prevent mislabeling, we successfully predicted the complete phase diagram, which was further validated through theoretical and statistical analysis. Notably, our methodology significantly alleviates the need to monitor long-term structural convergence, which is typically challenging due to the inherently slow phase evolution in attractive colloidal systems. This framework provides a robust and cost-effective tool for the systematic discovery and reverse engineering of complex soft condensed matter.

ABSTRACT

Samples were taken from 16 surface sediments (0-10 cm) and 12 core sediments from the drinking-water reservoir, the Wan’an Reservoir, which is located near small-scale and historical tungsten occurrences. The total concentrations and chemical speciation of As, Cd, Cr, Cu, Pb, Zn and W were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES) and the BCR sequential extraction procedure. Spatial distribution analysis indicated that toxic metal pollution exhibited significant downstream enrichment characteristics, among which Cd, W, and Cu were particularly prominent. The geo-accumulation and ecological risk analyses indicated that Cd was the dominant risk contributor. As a result, 87.5% of the surface sampling points were classified as having extremely high potential ecological risk. The Risk Assessment Code further indicated that the proportion of the acid-soluble/exchangeable fraction of Cd was relatively high, indicating strong mobility risk. Core sediment analysis indicated abrupt historical Cd enrichment peaks in the midstream area, while Zn and Cu exhibited surface enrichment over the past decade. Multivariate statistical analysis, along with geographical data on mining areas, revealed that mining activities were the primary anthropogenic source of complex pollution from Cu, Pb, Zn, W, and Cd in the downstream regions. In contrast, the middle and upper reaches are primarily influenced by natural geology and agricultural non-point sources. Comprehensive assessment suggests prioritizing the control of Cd migration in the downstream areas. In the middle and upstream regions, efforts should focus on preventing agricultural non-point source pollution to safeguard the reservoir’s water quality.

ABSTRACT

Incidence and mortality of oral cancer slightly decreased in recent years in Hungary; however, age-standardized estimated incidence and mortality for both sexes are still among the highest in Europe. The objective of the large observational study was to conduct oral cancer screening in Hungary using mobile screening units to examine 5000 individuals living in converging municipalities with low population density and under challenging socio-economic conditions. The study also aimed to develop related patient pathways, and to educate the population on the prevention of oral malignancies. The population screened for oral cancers using Visual Oral Examination (VOE) between 21 June 2021 and 31 March 2023 included individuals of 18 years of age or older, living in converging municipalities and in other geographical locations across Hungary. In 2024, a retrospective cross-sectional study was carried out to analyze the results. During the studied time period, a total of 8266 people attended the oral cancer screening study from converging municipalities (n = 4275; 51.7%), and from other geographical locations (n = 3991; 48.3%). Oral mucosal lesions were detected in 1725 individuals, of whom only 66 people (3.8%)-13 men and 53 women-visited a specialist, and 6 were diagnosed with malignant neoplasms. Mobile screening units can be an effective tool of secondary prevention for screening high-risk groups in rural, socio-economically challenging settings. However, low compliance of screen positive individuals to attend follow-up visits poses a threat to the effectiveness of the screening programs and it needs to be addressed by optimizing patient pathways.

ABSTRACT

PURPOSE: Antegrade continence enema (ACE) appendicostomy is widely used in children with complex colorectal and neurogenic bowel conditions, yet data from resource-constrained settings remain limited. We aimed to describe the experience of a single-center pediatric cohort in a low-middle-income country (LMIC).

METHODS: A retrospective review of all ACE procedures performed between 2012 and 2026 was conducted. Demographics, diagnoses, indications, complications, surgeries, and functional outcomes (assessed with Milan Bowel Function Questionnaire) were collected from clinical and operative records. Descriptive statistics were applied.

RESULTS: Forty-five children (80% male) underwent ACE procedures, with a median age of 8.3 years. Most had appendicostomy; two required cecostomy intraoperatively. The most common diagnosis was anorectal malformation (n = 33, 73.3%), followed by neurogenic bowel (n = 7, 15.5%). Eight patients (17.7%) underwent a concomitant Mitrofanoff procedure. The main complication was skin-level stricture (n = 17, 37.8%), representing the only indication for surgical revision (n = 15, 33.3%), with a median time to revision of 5.5 months. Nearly all patients achieved clinical success, with high satisfaction reported on the questionnaire.

CONCLUSION: ACE appendicostomy is an effective and satisfactory option in LMICs, with outcomes comparable to high-income settings, supported by careful patient selection and ongoing quality improvement efforts.

ABSTRACT

Pseudomonas aeruginosa is a clinically significant opportunistic pathogen characterized by intrinsic and acquired resistance mechanisms coupled with a diverse array of virulence determinants. This study investigated the distribution of P. aeruginosa in various clinical specimens (n = 382), its virulence genes, antimicrobial resistance patterns, and associations with total resistant P. aeruginosa (TRPA) phenotypes. The majority of isolates were recovered from sputum (24.3%) and endotracheal tube samples (22.5%). Virulence gene screening revealed moderate-to-high prevalence of lasB (55.0%), toxA (49.7%), pilA (53.7%), aprA (56.5%), phzS (45.0%), exoS (41.9%), and exoU (38.0%), indicating their widespread involvement in pathogenicity. Antimicrobial susceptibility profiling demonstrated the highest susceptibility to amikacin (56.3%) and gentamicin (52.4%), while resistance to carbapenems (imipenem 52.4%, meropenem 52.9%) and cephalosporins was alarmingly high. Based on resistance classification, 33.5% of isolates were MDR, and 9.7% XDR. Among ceftazidime-resistant isolates (n = 200), 83% harboured ESBL genes, with bla_CTX-M (38.0%) being most prevalent. Notably, 30.7% and 22.8% of isolates carried bla_NDM-1 and bla_OXA-48, respectively. Comparative analysis demonstrated statistically significant associations between TRPA phenotype and virulence genes: lasB (OR = 90.3), toxA (OR = 260.9), and pilA (OR = 32.6) (p < 0.0001). Resistance determinants such as bla_CTX-M (OR = 3.5), aac(6′)-Ib (OR = 2.9), qnrA (OR = 3.9), and co-carriage of NDM-1 + OXA-48 (OR = 4.9) were significantly enriched in TRPA isolates. These findings demonstrate a significant association between virulence and antimicrobial resistance traits, emphasizing the potential expansion of high-risk P. aeruginosa clones in clinical settings and highlighting the need for genomic surveillance and antimicrobial stewardship interventions.

ABSTRACT

While exposure to individual non-essential metals (NEMs) links to abdominal obesity (AOB), the NEM mixture effects and mechanisms remain unclear, particularly in vulnerable aging populations. We included 3795 community-dwelling Chinese older adults (age ≥ 60 years), measured 6 urine NEMs [gallium (Ga), arsenic (As), cesium (Cs), barium (Ba), thallium (Tl), and uranium (U)] via ICP-MS, defined AOB by sex-specific waist circumference, assessed insulin resistance (IR) via triglyceride-glucose (TyG) index, and determined vitamin D status by serum 25-hydroxyvitamin D [25(OH)D]. Multivariable logistic regression, mixture models [weighted quantile sum (WQS), quantile g-computation (QGC), and Bayesian kernel machine regression (BKMR)], mediation and moderation analyses, and network toxicology analyses were performed. Multivariable logistic regression showed a positive association between urinary Tl and AOB (OR = 1.18, 95% CI: 1.05-1.32). Mixture analyses consistently revealed a significant overall effect of NEMs on AOB, with Tl identified as the primary contributor (WQS weight = 0.481; QGC weight = 0.428; conditional PIP = 0.918). The TyG index was identified as a potential mediator, accounting for 10.18-7.84% of the associations between Tl and AOB and the NEM mixture and AOB, respectively. Vitamin D sufficiency [serum 25(OH)D ≥ 75 nmol/L] significantly attenuated TyG index-AOB association. Network toxicology identified the AGE-RAGE signaling pathway and several hub genes as candidate biological pathways for future investigation of the association between NEM exposure and AOB. These findings highlight the metabolic implications of NEMs, particularly Tl, and suggest that Vitamin D sufficiency may influence metabolic responses associated with AOB, offering novel insights into AOB prevention in the context of NEMs exposure.

ABSTRACT

Working memory issues are an often life-impairing deficit seen in several neurological disorders. Transcutaneous vagus nerve stimulation (tVNS) is a promising neuromodulatory adjunct to cognitive training and may improve working memory. High-density functional near-infrared spectroscopy (HD-fNIRS) is a modern neuroimaging modality that can assess cerebral blood flow in cortical areas. In the current study, we used HD-fNIRS to determine the effects of tVNS during a working memory task. Twenty-two healthy adult participants (12 female, 10 male) performed a 3-back task in a block design whilst high-density fNIRS was recorded across the bilateral prefrontal cortex using 36 sources and 48 detectors (1728 channels). Sham (earlobe) tVNS was delivered during the first task trial and active (tragus) tVNS was delivered during the second task trial. Statistical analysis was performed at a group level within trial (task – baseline) and between trials (active tVNS vs. sham tVNS) using node-level and regional approaches. Task-related increases in HbO were seen in the right dorsolateral middle frontal gyri, left inferior frontal gyrus and right lateral orbitofrontal cortex under both active and sham tVNS. Decreases were observed in the bilateral superior medial frontal gyri and medial orbital frontal cortices. No significant differences were seen between sham and active tVNS. Simultaneous recording of HD-fNIRS during a 3-back task and concurrent tVNS was feasible and well-tolerated. Robust task-related activation was seen in lateral frontal areas. No significant active-versus-sham differences in cortical activity or behavioural performance were observed under the stimulation parameters used here; however, this finding should be interpreted cautiously because the fixed-order design may have introduced fatigue or habituation effects. HD-fNIRS could be used in future studies of working memory and neuromodulation in clinical cohorts.
