Person-centred care (PCC) has been increasingly promoted in wound management, yet its theoretical foundations and practical application remain unclear. This scoping review aimed to map and synthesise how PCC frameworks, concepts and outcome measures have been used in wound care. Following the Joanna Briggs Institute methodology and PRISMA-ScR guidelines, a systematic search was conducted across major databases for studies published between 2020 and 2025. Eligible sources included empirical research, reviews and conceptual papers addressing PCC in adults with chronic wounds. Data were extracted and analysed descriptively across conceptual and evaluative domains. Fourteen publications met inclusion criteria. Only one explicit framework of person-centred wound care was identified. Most studies referred to patient-centred rather than person-centred approaches and applied principles such as empowerment, shared decision-making and communication without consistent theoretical grounding. Outcome assessment focuses mainly on clinical or functional indicators, with limited attention to relational or experience-based dimensions of care. Some studies used the term person-centred as an unreflected keyword. Person-centred wound management remains conceptually fragmented, methodologically heterogeneous and sometimes unreflected. Greater theoretical precision, consensus on terminology and development of validated frameworks and measurement tools are required to translate person-centred principles into consistent, evidence-based clinical practice.
To determine how people with post-COVID syndrome in Germany experience medical care and what healthcare problems they see in relation to post-COVID.
Semistructured interviews with a topic guide; audio-recording, transcription and analysis in terms of content.
13 digital interviews and one face-to-face meeting between April and June 2024.
14 German people with post-COVID syndrome (10 female; 4 male).
The experiences of the study participants in the care of their post-COVID symptoms were heterogeneous and suggested the continued, at least partially persisting, presence of problems in Germany that have already been addressed in the past. While other studies focus primarily on structural hurdles, our study provides indications that the interactions between healthcare professionals and patients may be important for their satisfaction with care. In particular, physician initiative, education and communication appear to play central roles. In addition, respondents often felt inadequately informed and reported problems with obtaining information. The level of knowledge about the disease in society as a whole has also been frequently criticised.
Doctor–patient interaction may be a critical factor in improving the care of post-COVID patients, with both supportive and problematic experiences indicating that empathic communication and transparent education can play an important role in reducing miscommunication and perceived stigma. In addition, people with post-COVID syndrome appear to need easier access to disease-specific information, which might be facilitated by expanded digital resources and additional dedicated support information services.
This study aims to investigate the association between physical fitness and markers of cognitive function in adults aged 40 and above in Qatar.
A cross-sectional study.
The Qatar Biobank, data of 1000 adults aged 40 and above.
A population of 1000 adults aged 40 years and older was included. Available data comprised measures of physical fitness including cardiorespiratory fitness, muscular strength, body composition and physical fitness capacity, as well as cognitive function assessed through tests of short-term visual memory and psychomotor coordination.
This paper investigated the physical fitness effect on cognitive functioning through short-term visual memory and psychomotor coordination testing. Logistic regression was used to measure the association between physical fitness and cognitive functioning tests.
Our study showed that lower physical fitness capacity was significantly associated with lower psychomotor coordination in females (OR=1.57, p=0.040) and showed no significant association in males (OR=1.65, p=0.062). For short-term visual memory, the association was significant in females (OR=1.68, p=0.042) unlike in males (OR=1.58, p=0.062). Males with greater muscle strength were about half as likely to have lower psychomotor coordination (OR=0.48, p=0.04). In females, a higher body fat percentage was associated with poorer cognitive function, with each 1% increase in body fat being linked to 6% higher odds of low short-term visual memory (p=0.02) and low psychomotor coordination (p=0.006). Cardiorespiratory fitness showed no statistically significant association with short-term visual memory and psychomotor coordination level in either sex.
Our findings suggest that overall physical fitness capacity is associated with better cognitive function in Qatari adults. The relationship between specific fitness measures and cognitive function varied by sex, with muscle strength having a stronger effect for males and body composition for females. These results highlight the potential importance of maintaining physical fitness for cognitive health in adulthood.
Glucocorticoid therapy is prescribed for a variety of inflammatory conditions and is associated with severe adverse effects. A glucocorticoid withdrawal syndrome (GWS) may occur after prolonged glucocorticoid treatment—with or without biochemical glucocorticoid-induced adrenal insufficiency (GIAI). Previously, GWS was not considered an entity, probably due to the overlap between symptoms of GWS and GIAI. The Addison’s disease-specific quality of life questionnaire (AddiQoL-30) is a validated tool for quantifying symptoms of adrenal insufficiency resembling GWS. In the present study, we test the hypothesis that patients with a low AddiQoL-30 score and/or low cortisol response to a short Synacthen test (SST), after cessation of prednisolone treatment, may benefit from low-dose hydrocortisone therapy without increasing the risk of metabolic and cardiovascular disease during prolonged cortisol exposure.
REPLACE is a multi-centre, double-blinded, placebo-controlled randomised controlled trial in patients with polymyalgia rheumatica or giant cell arteritis after cessation of prednisolone treatment. Criteria for randomisation are an AddiQoL-30 score ≤85 and/or plasma cortisol response to SST, 30-min p-cortisol >100 and 85; and (2) patients with a SST-stimulated cortisol ≤100 nmol/L.
The study is conducted in accordance with the Declaration of Helsinki, registered at the Clinical Trials Information System (CTIS: 2024-513822-53-00) and Clinicaltrials.gov (NCT05193396), and publications will be in accordance with the recommendations of the International Committee of Medical Journal Editors. The trial is monitored by local independent Good Clinical Practice units and overseen by the Danish Data Protection Agency (journal no. 21/27119), the Regional Committees on Health Research Ethics for Southern Denmark (project ID: S-20210076), the Danish Patient Safety Authority and the Danish Medicines Agency.
Objetivo: Interpretar las experiencias vividas del mundo subjetivo en mujeres violentadas por su pareja. Metodología: Estudio cualitativo en base a la Teoría de la Acción Comunicativa, realizado con 14 mujeres que acudieron al Taller de Relaciones Saludables implementado por la Secretaria de Salud de Aguascalientes. Se aplicó una entrevista semi-estructurada conformada por 7 preguntas sobre el mundo subjetivo. Resultados: Se obtuvieron 20 códigos que permitieron definir el siguiente fenómeno: La aceptación de la violencia como un estilo de vida, sin comprender el por qué permitir el abuso, lo cual origina sentimientos de autodestrucción física, emocional y familiar. Conclusiones: La sociedad ha construido una falsa igualdad cultural entre el hombre y la mujer; sin embargo, la ideología de la unión familiar le ha impedido a la mujer que se empodere y decida su forma de vida, esto lo transmiten a sus familias y éstas a su vez educan de tal forma a las mujeres, para que acepten “la vida que les tocó vivir”.
To identify the factors influencing the choice of private healthcare facilities among individuals experiencing tuberculosis (TB) symptoms.
Cross-sectional study.
The data for this study were obtained from a cross-sectional population-based TB prevalence survey conducted in 33 districts of Tamil Nadu, a state in southern India, between February 2021 to July 2022.
130 932 individuals, 15 years and above, residents of the selected cluster for the past 1 month, were included. Hospitalised patients, sick/morbid individuals and the institutional population were excluded.
Of 143 005 eligible individuals, 130 932 (91.6%) participated. Among them, 9540 individuals were found to have at least one TB symptom. Of these symptomatic individuals, 2678 sought healthcare, with 62.7% in the public facilities and 37.3% in private facilities. Factors associated with seeking care in the private healthcare facilities included working in organised sector (aOR: 1.3; 95% CI 1.0 to 1.7; p
Conversely, individual with symptom of weight loss (aOR: 0.4; 95% CI 00.3 to 00.6; p25 years (aOR: 0.6; 95% CI 0.4 to 0.9; p
The study highlights the distinct factors that could affect healthcare seeking for TB symptoms in the public and private healthcare settings for TB and the need for tailored interventions and customised healthcare policies to address such gaps and distinctions in care seeking.

The grey wolf (Canis lupus) population is expanding in parts of Europe due to legal protection and favorable ecological conditions. As wolves increasingly move into urban and suburban areas, interactions with domestic dogs become more frequent, raising the risk of pathogen transmission and posing potential threats to both wolf conservation and public health. This study investigated the health status of wolves in the Foreste Casentinesi National Park (Italy) using non-invasive fecal sampling conducted between May 2019 and March 2020. Samples were genetically analyzed to identify individuals and then screened for viral pathogens, Canine Coronavirus and Parvovirus, using PCR, Sanger sequencing, and phylogenetic analysis. Parasitological examinations were performed using flotation techniques on whole samples, and real-time PCR targeting Echinococcus granulosus and E. multilocularis was conducted on selected samples. Of the 260 samples collected, genetic analysis identified 80 individual wolves belonging to 8 packs. Only one sample tested positive for Coronavirus (1.2%), and none for Parvovirus. The detected sequence clustered with strains previously reported in wolves and foxes in Italy. Copromicroscopy revealed a high prevalence of veterinary-relevant endoparasites, including Eucoleus spp. (90.0%), Sarcocystis spp. (42.5%), Taeniids (28.7%), and Ancylostomatids (26.2%). Trichuris vulpis, Toxocara canis, and coccidia showed prevalence rates below 2%. All 104 samples tested for E. granulosus or E. multilocularis were negative. These findings suggest that while wolves in the FCNP commonly harbor several canine parasites, their role in the transmission of zoonotic pathogens appears limited. Although phylogenetic data suggest that coronavirus strains tend to cluster within wildlife species, molecular data on domestic dogs remain scarce. Nonetheless, the high prevalence of shared parasites highlights the need for ongoing surveillance in both wild canids and domestic carnivores. As wolves increasingly inhabit human-dominated landscapes, understanding disease dynamics at the wildlife–domestic interface is essential for effective conservation and public health strategies.by Wendy C.

Cockroaches are vectors of pathogens and parasites that pose public health risks, especially in developing countries with poor hygiene and inadequate infrastructure. This study aimed to identify the household factors associated with the occurrence of cockroaches and the helminth parasites they carry in a rural community. Data on household infrastructure, presence of domestic animals, and insect control methods were collected from 70 households in rural Guatemala. Cockroaches were captured using traps and manually. A Generalized Linear Mixed Model revealed that households with concrete roofs had 94% lower abundance of cockroaches than those with metal sheet roofs, while the presence of cats increased cockroach abundance by 2.6 times (p Moniliformis moniliformis, were identified, marking the first report of such parasites in household cockroaches in Guatemala. These results highlight the need for improved housing infrastructure and integrated pest management strategies to mitigate the risks associated with cockroach-borne parasites in vulnerable communities.Existing psychological and pharmacological interventions for young people at ultra-high risk (UHR) for psychosis have shown benefit in at least delaying the transition to psychosis, but they have limited benefit for comorbid disorders or social dysfunction, which are prominent for those at UHR. We developed a moderated online social therapy platform (named Momentum) including: (1) transdiagnostic therapeutic interventions targeting social functioning, depression, generalised anxiety and social anxiety; (2) a moderated, peer-led online community and (3) specialised human support from clinicians, career consultants and peer workers. The aim of this trial is to determine whether, in addition to treatment as usual (TAU), Momentum, a 12-month digital intervention, informed by the complex intervention framework, is superior to 12 months of TAU in improving social functioning in UHR young people.
The study design is a prospective, parallel group, rater-masked randomised controlled trial. We will recruit young people aged 14–27 years, meeting one or more UHR for psychosis criteria. Participants are randomly assigned to the condition using randomly permutated blocks with a 1:1 allocation ratio. Participants are stratified by age (

Cardiovascular disease (CVD) risk remains high but unevenly distributed in patients with type 2 diabetes mellitus (T2DM). Current risk stratification strategies are far from optimal, leading to both undertreatment and overtreatment of patients. The STENO INTEN-CT trial aims to evaluate a strategy of improved CVD risk management by using cardiac CT (coronary artery calcification (CAC)) for stratification and tailoring of multifactorial cardiovascular treatment based on CAC score. We hypothesise that (1) intensified medical treatment will lower CVD event rates in high-risk patients (CAC≥100), and (2) less intensive multifactorial treatment is safe in very low-risk patients (CAC=0).
The Steno INTEN-CT trial is an investigator-initiated, pragmatic, open-label, event-driven randomised controlled trial including patients with T2DM without known CVD. All participants (expected n=7300) will be invited for a non-contrast coronary CT scan. After the scan, participants will be randomised to either standard treatment (blinded for CAC results) or CAC-based treatment. Participants in CAC-based treatment and their general practitioner (GP) will receive information on CAC and a recommendation of multifactorial treatment. High-risk participants in the interventional arm will be invited for one or more initial study visits to intensify treatment with a combination of sodium glucose co-transporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, high-dose lipid-lowering, antihypertensive and antithrombotic treatment. Very low-risk patients in the interventional arm will be recommended less intensive treatment targets. After initial study-related activities, all participants will continue to be taken care of by their GP guided by specific treatment recommendations. The primary outcome in the primary hierarchical analysis (the rate of the combined CVD endpoint of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and hospitalisation for heart failure) will be monitored through national health registries. The trial is event-driven, but a median follow-up of 5 years is expected. Key secondary outcomes include patient-reported outcomes, quality-adjusted life years and healthcare costs.
The protocol V.1.9 is approved by the Research Ethics Committee and the Danish Medicines Agency and the Danish Data Protection Agency. The results of the study—positive, negative or neutral—will be published in peer-reviewed journals and through www.clinicaltrials.org.

Creative arts activities and mind-body practices, such as yoga, have been shown to benefit mental health and well-being. Research in higher education highlights the mental health challenges faced by students and staff in tertiary education; however, most studies on the potential of creative arts and mind-body practices have been conducted in the United States, with limited research investigating their impact in the UK higher education context. This qualitative study seeks to examine students’ and staff members’ views on extra-curricular creative and mind-body practices provided by one UK university, exploring how engagement in such activities can impact their understanding and awareness of mental health and well-being. In addition, it intends to investigate potential barriers to engagement with such activities. Drawing on questionnaire responses from 25 students and 20 staff members, findings highlight the effectiveness of art-based interventions and mind-body practices in raising awareness and understanding of mental health and well-being, while also having the potential to positively impact individuals’ mental health and well-being. Although personal interests and time restrictions may limit engagement, such activities were found to foster community-building, a particularly relevant factor in the post-Covid era, as institutions seek to re-engage students and staff through in-person activities. These findings have therefore important implications for the implementation of similar interventions in higher education and beyond to promote mental health and well-being awareness in diverse communities.Creating a healthy work environment requires balancing organizational goals with ethical responsibilities, where head nurses' ethical leadership can shape staff outcomes by mitigating work–family conflicts and promoting nurses' well-being, retention, and patient safety. This study aims to analyze the mediating role of work–family between head nurses' ethical leadership and nurses' reported errors, turnover intention, and physical and mental health.
Nationwide Multicenter cross-sectional study.
Validated self-report scales were used to assess nurses' perceptions of head nurses' ethical leadership, work–family conflict, error, turnover intention, physical and mental health. Descriptive and inferential analyses were conducted. Structural equation modeling examined the relationships among these variables based on Della Bella's and Fiorini's framework.
Data from 409 nurses across seven Italian hospitals was analyzed. The structural equation model showed an excellent fit. Head nurses' Ethical leadership was negatively associated with work–family conflicts, turnover intention, and errors, and positively associated with nurses' health. Work–family conflicts were significantly linked to turnover intention, errors, and nurses' health. Work–family conflicts mediate the relation between ethical leadership and turnover intention, errors, and nurses' health.
Promoting healthy work environments is crucial for nurses', patients', and organizations' well-being. Ethical leadership helps achieve this condition by reducing work–family conflicts, fostering nurses' well-being, decreasing turnover intention, and improving care quality. Disseminating ethical leadership programs and integrating with work–life balance policies can therefore strengthen both staff retention and organizational outcomes.
Ethical leadership can foster patient care, reduce turnover intention and errors, and improve nurses' well-being. Therefore, maintaining employee performance and organizational results requires integrating work–life balance policies with ethical leadership development programs.

The objective of this study was to examine whether different types of mental-imagery training focused on the vocal apparatus can enhance awareness of the vocal tract and diaphragm (vocal awareness) in non-professional singers.Sixty participants with no singing education received one of three training conditions: following instructions based on 1) a description of the physiological changes that take place during phonation (physiological description), 2) imitating an action using the vocal apparatus (imitative action), and 3) a metaphorical narration. Imitative action and metaphorical narration were conceptualized as more imaginative forms of training. Vocal awareness was assessed with a questionnaire that participants completed before and after the training. The questionnaire measured three indices: vocal apparatus representation, vocal apparatus interoceptive awareness, and vocal self-regulation. Results showed that all three types of training program significantly enhanced vocal awareness, but imitative action and metaphorical narration were more effective for interoceptive awareness, and metaphorical narration was more effective for self-regulation. In conclusion, the two imaginative forms of training were more effective than physiological description for improving vocal awareness.This study evaluates how participants experienced and assessed a three-round Delphi study on the terminology of developmental language disorders in childhood. It compares participants who completed all rounds (completers) with those who withdrew early (dropouts) and aims to derive methodological quality criteria for future Delphi studies.
The evaluation is based on a Delphi study conducted in 2021/2022 across five German-speaking countries. After the final round, n=179 experts (40% response rate) completed a standardised survey assessing their expertise, motivation, reasons for discontinuation, time commitment and perceptions of questionnaire and feedback design. Responses from completers (n=156) and dropouts (n=23) were analysed descriptively.
Most participants had no prior experience with Delphi methods but rated the study positively and considered the topic highly relevant. Completers reported their subjective time commitment to be lower and rated the handling of the questionnaire more positively than dropouts. Feedback was used by nearly half of all experts and was more actively considered by completers. Lack of time was the most common reason for discontinuation.
The findings confirm the feasibility and acceptance of the Delphi method in interdisciplinary health research. In addition to established methodological principles, topic relevance, clear communication and time commitment emerged as key areas for expert motivation and engagement.
This study aimed to identify intraoperative and perioperative factors influencing 30-day mortality after cardiac surgery and to develop a risk score (POP-score) for its prediction.
Retrospective cohort study with multivariable regression analysis.
A tertiary care cardiac surgery centre in Austria; data from consecutive patients undergoing cardiac surgery between 2010 and 2020 were analysed.
A total of 8072 patients were included. The cohort was randomly divided into a derivation cohort (75%) and a validation cohort (25%).
The primary outcome measure was 30-day mortality. We analysed associations between intraoperative and perioperative variables and 30-day mortality, assessed via multivariable regression analysis.
Several factors were significantly associated with 30-day mortality, including intraoperative RBC transfusion (OR 3.407 (95% CI 2.124–5.464)), postoperative high-sensitive cardiac troponin T cut-off levels (OR 2.856 (95% CI 1.958 to 4.165)), need for dialysis/haemofiltration (OR 2.958 (95% CI 2.013 to 4.348)) and temporary extracorporeal membrane oxygenation support (OR 5.218 (95% CI 3.329 to 8.179)) (p
The validated POP-score provides an improved tool for predicting 30-day mortality after cardiac surgery by incorporating intraoperative and perioperative factors alongside the EuroSCORE II. Although model performance was evaluated using 7-day peak troponin data, the score can be calculated within the first 72 hours postoperatively in most patients, supporting its clinical applicability for early decision-making, resource allocation and patient counselling. Further research is warranted to assess its clinical utility in diverse populations.

Homocysteine (Hcy), a sulfur-containing amino acid, is produced in prodigious quantities by the methionine cycle in the liver. Hcy is the major biomarker for cardio-vascular disorders and is associated with many other diseases. In previous work, we have explained why menstruating women have lower serum homocysteine than men due to higher concentrations of estradiol. In this study, we first present epidemiological evidence from NHANES data that synthetic estradiol supplementation lowers serum Hcy in post-menopausal women, but raises Hcy in pre-menopausal women. Secondly, we give an explanation of this puzzling phenomenon using previously developed mathematical models of one-carbon and glutathione metabolism. The simulation analysis demonstrated that the non-monotonic response of glutathione to rising estradiol levels may account for the differing Hcy responses to estradiol supplementation in postmenopausal versus premenopausal women, through activation of cystathionine β-synthase, a key enzyme regulating tissue homocysteine levels. Our findings further highlight the importance of considering menopausal status and synthetic hormone use when evaluating the health effects of homocysteine.To develop survey items for a national patient registry on Long COVID using a modified Delphi process.
This study was based on a modified Delphi process involving three rounds of anonymous, online surveys to develop consensus on and prioritise survey elements to be included in a minimum dataset for use in a national patient registry in Canada. Initial Long COVID items were identified through an environmental scan of the literature.
This study focused on healthcare systems in Canada and was conducted online.
A panel of 52 experts (patients, caregivers, clinicians and researchers) participated in all three rounds of the online survey. These participants were recruited through the Long COVID Web network and word of mouth.
In total, 243 survey elements related to care, quality of life and symptoms were included in round 1 of the survey. 200 reached consensus and moved to round 2 with two additional elements being developed based on open-ended responses. In round 2, participants ranked these survey elements and 34 advanced. In round 3, 33 survey elements met the threshold of consensus with one added a priori. The 33 survey elements were then used to develop a Long COVID minimum dataset, which consists of 48 items.
The findings affirm broad consensus for collecting data related to fatigue, post-exertional malaise, cardiovascular issues, respiratory problems and cognitive issues. This highlighted the desire for quality-of-life indicators and information related to care utilisation, quality and access.
Exercise-based interventions are well-established in reducing falls and fall-related injuries, but adherence and accessibility remain key challenges, particularly in rural areas. While conventional in-person training is widely used, digital interventions may offer scalable solutions to enhance engagement and reach. However, pragmatic trials evaluating the real-world effectiveness of conventional and digitally supported fall prevention interventions are lacking, limiting the evidence base for their implementation in routine healthcare settings. The SURE-Footed into the Future Fall Intervention Trial (SURE-FIT) aims to compare the effectiveness of two structured fall prevention interventions—a conventional centre-based exercise programme and a hybrid telemedical programme combining in-person and tablet-supported training—against a wait-list control group in reducing falls and fall-related injuries among community-dwelling older adults.
This study is a pragmatic three-arm, parallel-group, randomised controlled superiority trial with a 1:1:1 allocation ratio. Participants (≥65 years, community-dwelling, planned n=2778) will be randomly assigned to (1) conventional centre-based training supplemented with printed materials for home-based continuation (conventional group), (2) a hybrid model integrating centre-based and tablet-supported training for continuation (tablet group) or (3) a wait-list control group. The intervention includes a 9-week supervised phase followed by 43 weeks of independent home-based training. The primary outcomes are the incidence rate of falls and fall-related injuries over 12 months. Secondary outcomes include physical functioning, physical activity, concerns about falling, loneliness and the risk of low protein intake. A process evaluation will assess intervention feasibility and implementation. Additionally, qualitative interviews will be conducted with participants, course instructors and municipal stakeholders to explore experiences, facilitators and challenges related to programme participation and implementation. A health-economic evaluation will be conducted to assess the cost-effectiveness of the structured fall prevention interventions. Data collection will take place at baseline and every 3 months via standardised questionnaires, with a subgroup undergoing physical performance testing and sensor-based activity monitoring. Analyses will follow an intention-to-treat approach.
Ethical approval has been granted by the Ethics Committee of Ulm University (271/23). Written informed consent will be obtained from all participants before enrolment. Study findings will be disseminated through peer-reviewed publications, scientific conferences and national fall prevention initiatives. Additionally, results will be shared with key municipal representatives, and the German National Association of Senior Citizens’ Organisations (BAGSO). A publicly accessible website will provide ongoing access to study information and findings in plain language.

ObjectiveCalcium carbide-derived acetylene is widely used as an artificial fruit ripening agent despite its potential health risks. This study aimed to investigate the effects of sub-chronic exposure to crude acetylene on cardiometabolic parameters using a rodent model.
MethodsTwenty-four male Sprague Dawley rats were randomized into four groups: control (no exposure) and three test groups exposed to 58,000 ppm crude acetylene for 10, 30, or 60 minutes daily over 42 days. Body weight, fasting blood glucose, oral glucose tolerance, hepatic triglyceride levels, adipose tissue mass, liver enzyme activity, and oxidative stress markers were assessed. Histopathological analysis of liver tissue was also conducted.
ResultsAcetylene exposure did not significantly alter body weight but led to dose-dependent increases in central adiposity, hepatic triglycerides, and markers of oxidative stress. Higher doses were also associated with impaired glycemic control, elevated liver enzyme levels, and increased free heme concentration in plasma, suggesting oxidative damage and hemolysis. Histological analysis revealed central vein congestion and hepatic structural alterations in exposed groups.
ConclusionSub-chronic inhalation of crude acetylene induced metabolic dysfunction characterized by impaired glucose regulation, hepatic steatosis, and oxidative stress, despite no changes in overall body weight. These findings highlight the potential health risks associated with acetylene exposure and underscore the need for regulatory measures to limit its use in fruit ripening.
