This study aimed to evaluate the ability of social noncontact environmental enrichment to facilitate social buffering and to characterize the emotional experience of horses subjected to restraint in stock by assessing physiological parameters and facial expressions. Pantaneiro horses (n = 11) were evaluated in a crossover design with two treatments: social noncontact enrichment during stock restraint and social isolation during stock restraint. Physiological parameters (heart rate, heart rate variability, respiratory rate, ocular temperature by infrared thermography, and auricular temperature by infrared thermometer) and facial expressions (EquiFACS) were assessed throughout the 24-minute restraint period. When horses were accompanied by a conspecific, heart rate, respiratory rate, and eye temperature were lower (p nostril dilator (AD38), inner brow raiser (AU101), upper eyelid raiser (AU5), eye white increase (AD1), ears forward (EAD101), and ears back (EAD104), was also lower (pby Munawar Farooq, Uffaira Hafeez, Amir Ahmad, Susan Waller, Gabriel Andrade, Arif Alper Cevik, Syed Fahad Javaid
BackgroundStress is a prevalent issue among university students and is linked to adverse academic and emotional outcomes. While research emphasizes the roles of resilience, personality traits, and psychosocial factors, most studies are drawn from North American and European contexts.
ObjectivesThis is the first study of its kind in the United Arab Emirates (UAE) exploring the relationship between perceived stress, resilience, and personality traits among university students, offering insights into region-specific influences on emotional well-being.
MethodsAn online cross-sectional survey was conducted among 168 students from two colleges at the United Arab Emirates University (79% College of Medicine and Health Sciences, 21% College of Information Technology; 72% female). Data were analyzed using descriptive statistics and regression models in R version 4.2.0. Personality traits were assessed using the Ten-Item Personality Inventory, perceived stress was measured with the Perceived Stress Scale, and resilience was evaluated with the Brief Resilience Scale.
ResultsThe median perceived stress score was 22 (IQR: 17–28), and 30% reported high stress. Multivariable analysis showed that heavier academic workload, financial difficulties, lack of social support, lower physical activity, and poorer academic performance significantly predicted higher perceived stress, whereas resilience and emotional stability were protective.
ConclusionUniversity students’ perceived stress is closely associated with modifiable factors, including academic workload, social support, resilience, and physical activity. Targeted interventions, such as resilience training, promoting physical activity, optimizing academic schedules, and strengthening support services, are vital to reducing perceived stress and enhancing student well-being.

BackgroundRehabilitation and behavior change interventions are commonly used after lumbar surgery to improve recovery, but their effects on physical capacity and physical activity remain unclear. This study aimed to investigate the effectiveness of rehabilitation and behavior change interventions on physical capacity and physical activity behavior in patients following lumbar surgery for degenerative disease.
MethodsEMBASE, MEDLINE, PsycINFO, and CENTRAL were searched from inception to September 2025 and reference lists were hand-searched. Randomized controlled trials assessing rehabilitation or behavior change interventions on physical capacity or physical activity behavior in adults with lumbar degenerative disc disease who underwent lumbar surgery were included. Review author pairs independently extracted data and assessed included studies. Risk of bias was assessed with the Cochrane tool, and study quality with the Grading of Recommendations Assessment, Development and Evaluation classification. Results were pooled using random-effects models and reported as standardized mean differences (SMD) with 95% confidence intervals (CI).
ResultsExercise was more effective than minimal or usual care in improving trunk extension endurance in the immediate term (SMD, 1.54; 95% CI, 0.93–2.16). Supervised exercise outperformed self-directed exercise in improving trunk extension endurance in the immediate term (SMD, 1.28; 95% CI, 0.75–1.81). Psychologically informed rehabilitation was more effective than minimal or usual care in increasing physical activity levels in the intermediate term (SMD, 0.26; 95% CI, 0.02–0.49), but not in the immediate term (SMD, 0.17; 95% CI, −0.14 to 0.49). Physical activity advice did not increase physical activity levels compared to minimal or usual care in the immediate term (SMD, 0.21; 95% CI, −0.13 to 0.55). Prehabilitation was more effective than minimal or usual care in increasing physical activity levels in the intermediate term (SMD, 0.28; 95% CI, 0.03–0.53). Certainty of evidence ranged from low to moderate.
ConclusionsFor adults with lumbar degenerative disease who underwent lumbar surgery, exercise, especially supervised programs, improved trunk extension endurance in the immediate term. Psychologically informed rehabilitation and prehabilitation increased physical activity levels in the intermediate term, while physical activity advice showed no benefit. Findings are limited by low certainty of evidence and high risk of bias.

Iron is essential for normal physiological function, yet dysregulation of iron metabolism is increasingly recognized as a hallmark of cancers such as glioblastoma (GBM). Recent clinical evidence suggests that systemic iron deficiency anemia (IDA) negatively impacts GBM outcomes in a sex-dependent manner, but the mechanisms linking systemic iron availability to tumor iron metabolism remain poorly understood. Here, we interrogate the impact of systemic iron through dietary modulation (control, iron deficiency (ID), and high iron diets), stratified by sex, on tumor iron handling and GBM outcomes utilizing an immune competent (C57BL/6) GBM (GL261) mouse model. Subsequently, we analyzed clinical samples to evaluate translational value. In the preclinical study, we show that iron deficiency decreased survival in males but conferred a slight survival advantage in females, consistent with prior clinical trends. Among circulating iron markers, only ferritin light chain (FTL), but not ferritin heavy chain (FTH) or serum iron, positively correlated with survival in males but not females. In the brain, contralateral iron levels reflected dietary iron status in males but not females, further supporting sex-dependent regulation of local and circulating iron. Notably, tumor iron content remained unchanged in males but was significantly elevated in ID female tumors, complemented by increased transferrin receptor (TfR1) and FTH expression. In clinical GBM samples, we observed non-statistically significant but similar survival trends across varying iron and ferritin levels, suggesting potential translational relevance of our exploratory model. These findings demonstrate that systemic iron availability exerts a sex-specific effect on tumor iron handling, highlighting a critical relationship between systemic and tumor iron regulation in GBM.by Sandra S.

BackgroundUnderstanding the burden of acute viral respiratory infection-related hospitalizations is crucial for guiding research and development. Unlike influenza, respiratory syncytial virus (RSV), or severe acute respiratory syndrome coronavirus 2, no pharmaceutical interventions exist for other respiratory viruses; therefore, their impact remains poorly characterized. This study aimed to investigate the association of current non-vaccine-preventable respiratory viruses, especially rhinovirus/enterovirus (RV/EV), on hospitalizations during the respiratory seasons.
MethodsData from a prospective study that used multiplex polymerase chain reaction to conduct long-term surveillance on respiratory viruses in Valencia, Spain were analyzed. Patients aged ≥50 years hospitalized due to respiratory illness from 2014–15–2019–20 were included.
ResultsRespiratory viruses were detected in 35.2% (3,755/10,675) of hospitalized patients with acute respiratory illness. Influenza and RSV accounted for 22.1% of hospitalizations, RV/EV for 7.6%, and other non-vaccine-preventable viruses for 5.4%. Adults ≥75 years had average seasonal hospitalization incidence rates more than twice those aged 65–74 years and eight times those aged 50–64-year-olds. No significant differences in severity markers were observed among patients with or without virus identified, those aged ≥75 years had a 2–3 times higher mortality rate compared to younger age groups.
ConclusionsThe potential impact of respiratory viruses on hospitalization rates among older adults, particularly those aged ≥75 years, highlights the need for targeted interventions to reduce healthcare system burden. Enhanced diagnostic capabilities and the development of next-generation preventive strategies, including vaccines and therapeutics, could improve patient outcomes and strengthen the resilience of the healthcare system during respiratory virus seasons.

BackgroundPsoriasis, a chronic inflammatory skin disease affecting 2–3% of the global population, is driven by dysregulated immune responses. Despite advancements in biologic therapies, treatment challenges persist due to high recurrence rates. This study aimed to identify immune-related hub genes and elucidate their clinical implications in psoriasis pathogenesis and therapy.
MethodsMultiple microarray datasets from psoriasis patients (GSE30999, GSE106992, GSE14905, GSE78097, and GSE117468) were obtained to identify immune-key genes by differential gene analysis and Weighted Gene Co-expression Network Analysis (WGCNA). Subsequently, immune-related hub genes were identified using the Least Absolute Shrinkage and Selection Operator (LASSO) algorithm and Protein-Protein Interaction (PPI) networks, with further validation through Gene Set Enrichment Analysis (GSEA) and Receiver Operating Characteristic (ROC) curves to assess exploratory within-sample discrimination. Pearson correlation analysis evaluated the relationship between hub genes, skin lesion severity, and treatment outcomes. The study also conducted immune infiltration by using the Cell-type Identification by Estimating Relative Subsets Of RNA Transcripts (CIBERSORT) algorithm and identified potential therapeutic targets by the Drug-Gene Interaction Database (DGIdb).
ResultsThirty-one immune-related key genes were identified, and six hub genes (CLEC7A, CXCL1, IRF1, S100A12, S100A8, S100A9) were validated as central players in immune signaling pathways. These genes exhibited within-sample discrimination (AUC > 0.9) and correlated with disease severity and biological therapy efficacy. Immune infiltration analysis revealed increased activated memory CD4+ T cells and M1 macrophages in lesional skin, which was strongly associated with hub gene expression. Additionally, drug-gene interaction analysis identified potential therapeutic agents targeting these genes.
ConclusionThis study identified six immune-related hub genes that were closely linked to the severity of psoriasis, the effectiveness of biological treatments, and infiltrated activated memory CD4+ T cells and M1 macrophages. Our findings elucidate a novel immune-related hub gene network in psoriasis and provide potential targets for the development and application of biologics.

Insecticide resistance in malaria vectors remains a global public health problem; however, little is known about resistance levels in Osun State, despite relatively high rates of malaria and distribution of insecticide-treated nets in the area. This study evaluates the resistance status of adult female Anopheles gambiae s.l to pyrethroids (permethrin, deltamethrin and alpha-cypermethrin) and an organophosphate (pirimiphos-methyl) insecticides and knockdown resistant (KDR) gene detection in six locations (Ido-Osun, Ipetumodu, Inisa, Ejigbo, Ijebu-Jesha and Ila) across the three senatorial districts in Osun State, Nigeria. Larval sampling was done between 0700hr and 1100hrs weekly between January and December 2022. Collected larvae were reared to the adult stage in the Department of Animal and Environmental Biology laboratory of Osun State University, Osogbo, Nigeria and then identified morphologically using morphological keys. Insecticide bioassay was conducted with permethrin (0.75%), deltamethrin (0.05%), alpha-cypermethrin (0.05%) and pirimiphos-methyl (0.25%) using WHO procedure. The mosquitoes were subjected to molecular analysis to detect the KDR gene. Pirimiphos-methyl showed significantly higher knockdown at 60 minutes (KD60) and achieved 100% mortality compared with the pyrethroids tested (p Anopheles gambiae s.l as compared to pyrethroids. Therefore, there is a need to intensify insecticide resistance surveillance of Anopheles in Osun State to plan indoor residual spraying with pirimiphos-methyl and explore the use of PBO or dual active ingredient insecticides treated nets (ITNs) to address the potential impacts of pyrethroid resistance.by Esther Ortega-Martin, Javier Alvarez-Galvez
ObjectiveTo characterize the heterogeneity of Long COVID (LC) by identifying distinct patient profiles based on symptoms and quality of life (QoL), and to examine the sociodemographic and clinical predictors associated with these profiles.
Study designA cross-sectional observational study was conducted.
MethodsWe recruited 363 patients with LC in Spain via an online survey. Symptom patterns were identified through latent class analysis of 15 binary symptoms. QoL was assessed with the patient-derived LC-6D-QoL across six dimensions, and cluster analysis defined QoL subgroups. Logistic regression was applied to examine clinical and sociodemographic predictors of QoL profiles.
ResultsTwo symptom profiles emerged: a low-burden profile, dominated by fatigue and cognitive problems, and a high-burden profile with multisystem involvement. QoL clustered into three profiles—high, middle, and low QoL—with more than half of participants in the low QoL group. Symptom burden and employment status were the strongest predictors of poor QoL, whereas age, sex, education, and income showed limited associations. Social support was more frequently reported among participants with low QoL.
ConclusionsLC is characterized by distinct clinical and QoL profiles, with strong interactions between multisystem symptom burden and social determinants. Identifying patients at greatest risk of poor QoL can inform stratified interventions and integrated policies that combine medical care, psychosocial support, and workplace reintegration.
Extrapulmonary tuberculosis (EPTB) poses a significant diagnostic and economic challenge in HIV endemic, low-resource settings due to its complex presentation and current diagnostic tools limitations. While accurate and timely diagnosis is critical for reducing morbidity, mortality and health system costs, economic evaluations of EPTB diagnostics remain sparse and fragmented. This protocol aims to map existing evidence on the economic evaluation of diagnostic innovations for EPTB in low-resource settings.
This scoping review protocol follows the Joanna Briggs Institute (JBI) methodological framework and registered on the Open Science Framework.

Staphylococcus aureus (S. aureus) bacteraemia is a common and severe infection. With mortality rates ranging from 20–30% and long-term impairments in over a third of survivors, better treatments are urgently needed. Linezolid, a well-established treatment for pneumonia and complicated skin infections, has been shown in preclinical studies to strongly suppress S. aureus virulence factors critical to bacterial persistence and tissue damage. Hence, we aim to investigate whether the addition of linezolid to standard therapy in patients with S. aureus bacteraemia leads to an overall improvement in patient-relevant outcomes.
We will conduct a two-arm, parallel-group, multicentre, randomised controlled trial (Linezolid Plus Standard of Care) in 12 hospitals in Switzerland with blinded treating physicians, patients and outcome assessors. Hospitalised patients aged ≥18 years with S. aureus bacteraemia will be eligible. Patients will receive standard antibiotic treatment as prescribed by the treating physician. Within 72 hours of collection of the blood sample yielding the first positive blood culture, patients will be enrolled and randomised 1:1 to receive either adjunctive linezolid (600 mg orally two times per day for 5 days) or placebo. To determine patient-relevant outcomes, we implemented a comprehensive patient-representative consultation process. Consequently, we will use the desirability of outcome ranking (DOOR) established for S. aureus bacteraemia as the primary outcome at 90 days. The hierarchical composite DOOR outcome includes the following four components, ranked from most to least important: (1) survival, (2) return to level of function before S. aureus infection, (3) complications leading to treatment changes and serious adverse reactions; and (4) hospital length of stay. This approach will allow us to analyse the win ratio, that is, whether patients receiving linezolid have a better DOOR rank compared to patients in the placebo group. We calculated a target sample size of 606 patients providing 90% power at a two-sided significance level of 0.05.
Ethical approval was received from the Ethics committee for Northern and Central Switzerland (BASEC number 2025-00655). Eligible patients will be informed about the study by the local study team and asked for written consent if they wish to participate. For patients unable to provide informed consent, an appropriate substitute (ie, a close relative or a physician not involved in the research project) may make decisions based on the presumed wishes and the best interest of the patient. The patient’s own consent will be obtained as soon as their condition permits. Results will be published in peer-reviewed journals and in laymen's terms through various channels (social media, Swiss national portal HumRes).
Visual impairment is reported to affect 40%–50% of children with cerebral palsy (CP). Vision difficulties in the context of rehabilitation are often under-recognised, under-treated and therefore under-studied, pointing to an urgent need for the development of evidence-based vision interventions for infants and toddlers with cerebral vision impairment (CVI). We present the protocol of a multisite pragmatic pilot randomised controlled trial (RCT) of feasibility, acceptability and preliminary efficacy of an early vision-awareness and parent-directed environmental enrichment programme for infants with or at risk of CP under 7 months corrected age (CA) with vision impairment.
The main objective is to determine the feasibility and acceptability of the Vision Intervention for Seeing Impaired Babies: Learning through Enrichment (VISIBLE) intervention. We will estimate the preliminary effects of the programme on infants’ visual functions and early development, as compared with standard community-based care (SCC).
A two-group RCT will be conducted. Infants at 3–6 months at entry, with severe visual impairment and at high risk of CP, will be enrolled and randomised (n=16 per group) to receive the VISIBLE intervention compared to SCC. Randomisation will be completed through an independent automated process (Research Electronic Data Capture). VISIBLE intervention will be delivered by a therapist through home visits (90–120 min) once every 2 weeks. Completion of 10 visits (80% of the intervention target dose) within 6 months is required for adherence to the VISIBLE trial. Outcome will be assessed at 12 months CA. Visual function will be evaluated with the Infant Battery for Vision, motor outcomes with the Peabody Developmental Motor Scales, Second Edition. Developmental quotients, infant quality of life, parent well-being and parent-infant relationship will be also monitored through standardised tools.
The enrolling sites have historically demonstrated rapid and effective translation of successful evidence-based interventions into routine clinical practice, as well as the dissemination of the findings through local, national and international scientific meetings.

Poor communication between healthcare professionals is one of the main causes of medical errors. Many articles about interprofessional communication (IPC) do not define what communication is and often describe it only as a domain of competencies of interprofessional collaboration. Three communication paradigms coexist: the transmission model, the transactional model and the constitutive model. These models focus on different aspects of communication and are complementary. No review about IPC, including all healthcare professionals or all healthcare settings, has been found.
A scoping review protocol was developed to map the research on the topic of IPC, the paradigms of communication used by the researchers, as well as to clarify the definition of this concept. We will follow the Joanna Briggs Institute methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. Eligibility criteria follow the Population, Concept, Context framework. Articles about health professionals, allied health professionals and social workers and students in these fields will be included. Articles evaluating IPC in healthcare, either quantitatively or qualitatively, will be included. Articles investigating IPC in any type of healthcare setting in any country will be considered. All types of published articles in scientific journals will be included. The databases that were searched are MEDLINE, CINAHL, APA PsycINFO, EMBASE and Web of Science. In October 2025, 22 798 citations were retrieved, of which 9722 duplicates were deleted. Two researchers will then independently assess the remaining 13 078 citations against the eligibility criteria. This step is scheduled for completion in May 2026. They will then chart the data using a standardised data extraction tool.
Formal ethical approval is not required, as primary data will not be collected in this study. Findings of the scoping review will be disseminated through professional networks, conference presentations and publication in a scientific journal.
Because the study is a scoping and not a systematic review, registration was not possible on PROSPERO. The study was registered on Open Science Framework: https://osf.io/dyh2a.
Funnel plots are used to identify intensive care units (ICUs) with a higher than expected risk-adjusted mortality. ICUs with a standardised mortality ratio (SMR) within pre-defined control limits (often the 99.8% CL) are regarded as ‘in control’ and not labelled as a potential outlier for a particular calendar year. However, increased mortality rates not due to random fluctuations within and across the calendar years may be overlooked. We examined whether statistically significant and relevant differences in mortality over time between ICUs regarded as ‘in control’ are present.
A longitudinal register-based study.
88 ICUs in the Netherlands registering the admissions of all critically ill patients in the National Intensive Care Evaluation registry in the Netherlands from 2013 to 2023.
Hospital death analysed in a multivariable logistic regression analysis with a random intercept for ICU. The random intercept variance was translated to the median OR (MOR).
877 ICU-calendar year combinations were included, covering 759 498 unique admissions. The MOR increased from 1.12 (95% CI 1.10 to 1.15) for ICU-calendar year combinations with an SMR within the narrowest 95% CL (N=677) to 1.20 (1.17 to 1.24) for combinations with an SMR within the expanded 99.8% CL (including adjustment for overdispersion) (N=194) and to 1.21 (1.17 to 1.25) when including all ICU-calendar year combinations. Similar results were found for separate calendar years and separate diagnostic groups.
These results show differences in mortality between ICUs that were not labelled as outliers. Assessment of mortality performance should integrate cross-sectional funnel plots, the MOR and longitudinal trends in the SMR to better capture persistent patterns of excess risk.
Self-injurious behaviour (SIB) consists of persistent, repetitive movements that can result in serious injury without suicidal intent. These behaviours are prevalent among children with neurodevelopmental disorders, including profound autism. Although many individuals benefit from currently available therapies, some exhibit treatment-refractory SIB that necessitates ongoing use of personal protective equipment and restraint, presumably due to stronger neurobiological drivers. We recently completed a phase I, open-label clinical trial demonstrating the safety, feasibility and preliminary efficacy of bilateral deep brain stimulation targeting the nucleus accumbens (NAc-DBS) in children with profound autism and severe, refractory SIB. The objective of the proposed study is to characterise the effectiveness of NAc-DBS in treating severe, refractory SIB in this unique and vulnerable population.
A single-centre, randomised double-blinded, crossover trial is proposed. Informed by the results of our pilot study, 25 subjects with autism spectrum disorder and severe, refractory SIB will undergo bilateral NAc-DBS. Following a 4-week recovery period, participants will be randomised to either group A (stimulation ON then OFF) or group B (stimulation OFF then ON). Each block will last 12 weeks, separated by a 2-week washout period. Following completion of the second block, all participants will enter a 6-month open-label phase with stimulation ON. The primary outcome is the difference in the Repetitive Behaviour Scale–Revised total score, between DBS-ON and DBS-OFF conditions. Secondary outcomes include measures of quality of life, caregiver burden, daily logs of SIB events and direct observation of SIB under structured analogues.
The proposed trial has been approved by the institutional Research Ethics Board (1000081171). Trial results will be disseminated through peer-reviewed publications and conference presentations.
To investigate the risk factors for primary non-central malposition of peripherally inserted central catheter (PICC) tip in neonates admitted to the neonatal surgical department, compare the malposition rates across different insertion sites in disease types, and explore whether different diseases affect PICC tip malposition.
A retrospective case–control study conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement.
A 3A women’s and children’s hospital in South China (Guangdong Province).
A total of 558 neonates aged ≤28 days who underwent PICC insertion between January 2019 and November 2024 were enrolled. Neonates with congenital circulatory system malformations, incomplete clinical data and death or treatment withdrawal before tip positioning were excluded.
The primary outcome was the incidence of primary non-central PICC tip malposition confirmed by X-ray or ultrasound within 24 h after insertion. Secondary outcomes included comparison of primary non-central PICC tip malposition rates across different insertion sites and comparison of primary PICC tip malposition rates by insertion sites across different disease groups.
558 neonates were included in this study, including 460 cases with PICC tip in place and 98 with PICC tip malposition. In binary logistic regression analysis, the PICC insertion site was considered an independent risk factor (OR 2.908, 95% CI 1.748, 4.840, p
Medical staff can choose appropriate upper or lower limb veins for PICC insertion without worrying about the impact of abdominal diseases or thoracic diseases on non-central PICC tip malposition. PICC insertion via the head and neck veins should be performed with caution in neonates, as these sites carry a high risk of primary non-central tip malposition compared with other insertion sites.
Chronic wounds represent a major global health and economic burden. Smart wound dressings integrate biosensing and stimuli-responsive materials to monitor and modulate biological parameters within the wound microenvironment. This scoping review maps the biological parameters monitored by smart wound dressings, an area not previously synthesized across preclinical and clinical contexts. Following Joanna Briggs Institute (JBI) and PRISMA-ScR frameworks, five databases were searched in March 2025. Studies published between 2008 and 2025 reporting biosensing or responding technologies in wound dressings were included. A total of 179 studies met the inclusion criteria, most being preclinical (in vitro or in vivo rodent models), with few human investigations. The most frequently monitored parameters were pH, temperature, oxygenation, moisture, bacterial burden, and protease activity (particularly MMP-9). Preclinical data showed enhanced collagen deposition, angiogenesis, and infection control compared with conventional dressings, whereas human studies mainly assessed feasibility and biocompatibility. Smart dressings demonstrate strong technical and biological performance, but clinical validation and standardized outcome reporting remain limited. Future interdisciplinary research should prioritize well-designed clinical trials to confirm therapeutic and economic benefits and enable translation into personalized wound care.
Calcium sulphate (CS) is a fully synthetic, sterile, bioabsorbable biomaterial extensively applied for the management of infected tissues and postoperative dead spaces resulting from surgical interventions. Residual DS may facilitate hematoma accumulation and bacterial colonisation, thereby heightening the risk of surgical-site infections. Within orthopaedic surgery, CS has been predominantly evaluated as a bone-void filler and an off-label antibiotic delivery vehicle—particularly in arthroplasty revisions, chronic osteomyelitis, and open fractures—yielding high rates of infection prophylaxis, bone regeneration, and low complication profiles. Commercially available as injectable ‘pearls’ or beads, CS permits local, sustained antibiotic elution while undergoing gradual biodegradation, thus obviating the need for secondary removal procedures. Over the last decade, Calcium Sulphate beads (CSBs) have transcended orthopaedics, gaining traction across general, vascular, and endocrine surgery disciplines for the prevention and treatment of complex wound infections. However, their application in plastic and reconstructive surgery remains underreported, despite the specialty's frequent engagement with complex soft-tissue defects, bone exposure, suture dehiscence, and trauma-related wounds vulnerable to infection. To our knowledge, this represents the first scoping review synthesising current evidence, clinical indications, and emerging roles of CSBs within plastic and reconstructive surgery.
Burn injuries pose a significant challenge in resource-limited settings, particularly during humanitarian crises. This study examines the epidemiology, management, and outcomes of burn patients at a tertiary hospital in Damascus, Syria, from 2021 to 2024. A single-centre retrospective cohort study was conducted on 500 admitted burn patients. Data on demographics, injury characteristics, management, complications and mortality were analysed using descriptive statistics, chi-square tests, Mann–Whitney U tests and binary logistic regression. The lethal area 50% (LA50) was estimated using the logistic regression equation: LA50=−constant+∑bixibTBSA$$ LA50=-\frac{constant+\sum \left({b}_i{x}_i\right)}{b_{TBSA}} $$. The mean patient age was 20.5 ± 17.9 years, with a male predominance (55%). Flame burns (72.4%) at home (87.6%) were most common. The mean total body surface area burned was 30.99% ± 21.31%, with 68.6% being full-thickness injuries. The complication rate was 91%, with infection being most prevalent. The overall mortality rate was 39%, with sepsis (56.4%) as the leading cause. Logistic regression identified larger burn area (OR = 1.152, p < 0.001), full-thickness depth (ref. partial thickness, OR = 0.281, p < 0.001), older age and female gender as independent predictors of increased mortality. Deceased patients had significantly shorter hospital stays. LA50 was 42.63% for a 40-year-old male with a partial-thickness flame burn and a 10-day hospital stay; for a female with a full-thickness flame burn under the same conditions, it was 27.43%. This study reveals an alarmingly high burden of burn injuries in a crisis-affected setting, with extreme complication and mortality rates. The findings highlight the critical impact of extensive burns and sepsis, underscoring severe systemic constraints on care. Urgent context-specific interventions to strengthen acute burn management, infection control, and prevention strategies are imperative.
Chronic wounds cause a significant burden to affected patients and to society. Effective and objective diagnostic and monitoring methods are needed in wound care, and artificial intelligence offers one promising alternative. In this study, real-world wound images were used to train a convolutional neural network to automatically segment wound area and wound tissues on an image. The study included altogether 362 images of venous, arterial, vasculitis and pyoderma gangrenosum wounds. The model was based on a convolutional neural network architecture U-Net, and fully supervised learning was utilised during the training phase. Wound area reached a Dice Similarity Coefficient (DSC) of 0.927 and Intersection over Union (IoU) of 0.868 using an augmented dataset with pretraining. Fibrinous exudate and granulation performed fairly well with DSC 0.750 and 0.696, and with IoU 0.659 and 0.601, respectively. Necrosis present in only 56 images achieved lower performance with DSC 0.503 and IoU 0.502. In conclusion, this study suggested that it is possible to train a neural network to perform well with images taken for purely clinical purposes. Besides wound area, several wound structures can be identified, but wound structure identification performance is dependent on the number of images featuring the structure.
