To identify distinct social network types among young-old adults based on the characteristics of social network structure and to explore the relationship between different types, socio-demographic characteristics and subjective cognitive decline.
A cross-sectional study was conducted from July 2022 to October 2023.
A total of 652 young-old adults aged 60–74 years completed the sociodemographic questionnaire, the subjective cognitive decline questionnaire-9 and the self-designed egocentric social network questionnaire. The types of social networks were identified by latent profile analysis. Univariate analysis and binary logistic regression were used to analyse the influencing factors of subjective cognitive decline.
The incidence of subjective cognitive decline was 38%. Social networks of young-old adults tended to be large, predominantly family-centred and characterised by strong contact strength, high density and significant demographic heterogeneity among network members. Four social network types were identified: diverse-moderate, family-dense, family-strong and friend-loose. Young-old adults embedded in the family-dense and family-strong types were more likely to develop subjective cognitive decline than those in the diverse-moderate type. Additionally, age, education level, previous occupation, daily sleep duration and exercise were related to the incidence of subjective cognitive decline.
The findings highlight the relatively high incidence of subjective cognitive decline in young-old adults that is notably influenced by the type of social network they are embedded in. More attention needs to be paid to identifying and supporting young-old adults at high risk of subjective cognitive decline, especially to promote their social integration and friend network building, to improve their subjective cognitive function.
The findings emphasise the importance of considering the structure and composition of social networks when addressing subjective cognitive decline among young-old adults. A diversified social network incorporating both familial and friendship ties may provide enhanced cognitive protection. Therefore, interventions targeting subjective cognitive decline should promote the expansion of friendship-based relationships and foster the development of more heterogeneous and multi-source networks.

The study aims to investigate patients' perceptions of recurrence risk associated with atrial fibrillation, with the goal of establishing a theoretical foundation for developing future measurement scale and intervention strategies.
A qualitative interview study.
Seventeen patients diagnosed with atrial fibrillation at a Grade-A tertiary hospital participated in semi-structured, in-depth interviews conducted between October and December 2024. Participants were selected via purposive sampling. The data were analysed employing thematic analysis in accordance with Colaizzi's method. The study adhered to the Consolidated Criteria for Reporting Qualitative Research checklist.
The perceptions of recurrence risk among patients with atrial fibrillation can be summarised into five themes: (1) perceived likelihood of recurrence, (2) perceived severity of recurrence, (3) perceived triggers of recurrence, (4) emotional reaction to recurrence, and (5) efficacy perception of managing recurrence risk.
Perceptions of recurrence risk among patients with atrial fibrillation are diverse and often underestimated due to limited knowledge and subjective symptom interpretation, affecting health behaviours. Understanding patients' subjective appraisals, emotions, and perceived efficacy is essential. Validated assessment tools and tailored risk communication may enhance self-management and support targeted interventions.
This study provides critical insights into how atrial fibrillation patients perceive their risk of recurrence. It also provides a theoretical foundation for creating validated assessment tools and tailoring individualised health education and intervention programmes.
Patients were involved in the study design, data collection, and interpretation of findings. Their contributions included providing feedback on the initial interview guide to ensure relevance and clarity, participating in in-depth interviews to share their lived experiences with atrial fibrillation recurrence, and offering reflections on key themes emerging from the data.

Vascular dementia (VaD), a neurodegenerative disease driven by vascular pathology, requires multi-targeted therapeutic strategies. This study employs an integrated in silico approach to evaluate the neuroprotective potential of natural ligands against key proteins implicated in VaD pathogenesis. Using molecular docking and normal mode analysis (NMA), four natural compounds (Galangin, Resveratrol, Curcumin, and Licocumarone) were assessed for their binding affinity and structural influence on six target proteins: APLP1, APOE, CLDN5, SOD1, MMP9, and MTHFR. Docking analysis revealed that galangin exhibited the highest binding affinity to APLP1 (−8.5 kcal/mol), resveratrol to MTHFR (−8.1 kcal/mol), and curcumin showed dual efficacy toward APOE (−7.2 kcal/mol) and MMP9 (−8.0 kcal/mol). Licocumarone demonstrated notable stabilization of CLDN5 and SOD1. The NMA results indicated ligand-induced stabilization of protein cores and enhanced flexibility in loop regions, which may impact amyloid aggregation, oxidative stress, and blood-brain barrier integrity. Pathway enrichment using the KEGG and Reactome databases identified significant involvement of the IL-17 and TNF signaling pathways, along with leukocyte transendothelial migration, linking inflammation with vascular dysfunction. APOE emerged as a central node within the protein-protein interaction network, highlighting its regulatory importance. This study highlights the therapeutic relevance of natural ligands as cost-effective modulators of multiple VaD-associated pathways. The combined use of molecular docking, protein dynamics, and enrichment analyses provides a comprehensive computational framework for early-stage drug discovery. These findings warrant further experimental validation to advance the development of targeted, mechanism-driven interventions for vascular dementia.by Linlin Bao, Haibo Zhao, Haiyue Ren, Chong Wang, Su Fang
Hair follicle stem cells (HFSCs) play critical roles in adult hair regeneration, owing to its self-renewal and multipotent differentiation properties. Emerging evidence has shown that long noncoding RNAs (LncRNAs) are implicated in biological processes such as proliferation, differentiation and apoptosis. However, the specific role of LncRNA RP11-818O24.3 in regulating HFSCs remains unclear. To explore the effect of LncRNA RP11-818O24.3 on HFSCs, stable LncRNA RP11-818O24.3 overexpression and knockdown HFSCs were established using a lentivirus vector system. The effect of LncRNA RP11-818O24.3 on proliferation was evaluated by Cell Counting Kit-8 (CCK8) and EdU incorporation experiments. The differentiation of HFSCs into neurons and keratinocyte stem cells was detected by immunofluorescence staining. We showed that LncRNA RP11-818O24.3 overexpression promoted the proliferation and inhibited cell apoptosis in HFSCs. High levels of LncRNA RP11-818O24.3 promoted the differentiation of HFSCs into CD34+K15+ keratinocyte progenitors and CD34+Nestin+neuron-specific enolase (NSE)+ neural stem cells. Additionally, LncRNA RP11-818O24.3 increased fibroblast growth factor 2 (FGF2) expression and the subsequent activation of the PI3K/AKT signaling pathway. These data demonstrated that LncRNA RP11-818O24.3 promotes self-renewal, differentiation, and the capability to inhibit apoptosis of HFSCs via FGF2 mediated PI3K/AKT signaling pathway, highlighting its potential role as a therapeutic strategy for treating hair loss diseases.Video-assisted thoracoscopic surgery (VATS) has become the predominant method for lung cancer diagnosis and resection, with over 80% adoption in relevant surgeries. With technological advancements, uniportal VATS is now widely employed. However, it still poses a significant risk of moderate to severe acute postoperative pain, potentially leading to chronic post-thoracotomy pain syndrome (PTPS). Therefore, effective postoperative analgesia is crucial. Regional block techniques have gradually gained wide attention. Specifically, paravertebral block (PVB) has been considered the ‘gold standard’ for thoracic analgesia, but its application involves risks due to the challenging anatomy. The erector spinae plane block (ESPB) and intertransverse process block (ITPB) have emerged as alternatives. ESPB showed non-inferiority to PVB in pain management and recovery quality. However, the mechanism of ESPB and its consistency in providing analgesia are not fully understood. ITPB, targeting the ‘posterior space of the superior costotransverse ligament’, offers theoretical advantages in drug diffusion due to its closer proximity to the paravertebral space than ESPB. Despite these advancements, there is a lack of randomised controlled trials (RCTs) assessing the comparative efficacy of continuous ESPB and ITPB. This study aims to address these gaps by comparing the analgesic effects and recovery quality of continuous ESPB and ITPB in patients undergoing single-port VATS.
A double-blind RCT will be conducted, enrolling 96 patients electively undergoing single-port thoracoscopic surgery, randomly assigned to either the experimental group (ITPB group) or the control group (ESPB group). After routine surgery, block intervention and continuous pump catheterisation will be performed. The primary assessment will be the numeric rating scale (NRS) scores at 24 hours. Secondary outcomes include NRS at other time points, block effectiveness, Quality of Recovery-15 scores and chronic pain-related scores. Evaluations will be conducted at 0, 2, 6, 12, 24 and 48 hours. Additional assessment indicators include time to first self-administration of pulse analgesia pump, number of self-administrations within 48 hours, use of non-steroidal anti-inflammatory drugs and opioids postoperatively, Comprehensive Complication Index (CCI) score, length of hospital stay, incidence of adverse events and complications, patient satisfaction score and assessment of PTPS incidence at 3 months postoperatively using the Brief Pain Inventory short form and the Short-Form McGill Pain Questionnaire.
The study was reviewed and approved by the Medical Ethics Committee of the Fifth Affiliated Hospital of Sun Yat-sen University (No. K44-1, 2024). The results of the study will be submitted for publication in a peer-reviewed journal with online accessibility.

This study analysed the clinical outcomes and healthcare costs associated with diabetic foot ulcer (DFU) within a tertiary healthcare centre in Singapore.
This is a retrospective, single-centre study. Patient data were extracted from the hospital’s electronic health system, including demographic, clinical and hospitalisation information. Hospitalisation costs were categorised into DFU-related and other hospitalisation costs. A one-way sensitivity analysis was performed to estimate the total healthcare costs associated with DFU.
Tertiary centre within a population suffering from a diabetic epidemic.
All patients aged 18 years or older who received DFU treatment between January 2019 and December 2023 at the Singapore General Hospital were included.
A total of 2857 DFU patients were included in the study. In-hospital mortality remained stable at 5%–6% annually. Among the cohort, 39.1% underwent minor amputations, 19.6% had major amputations and 9.0% experienced both minor and major amputations. The median length of stay for surgical patients ranged from 10 (IQR 4–24) to 13 days (IQR 6–31), compared with 4 (IQR 2–8) to 5 (IQR 3–9.5) days for non-surgical patients. Total costs per admission for patients with DFU-related surgery ranged from US$28 588.96 to US$34 204.77, while for those without surgery, costs ranged from US$6637.59 to US$7955.23. Total hospitalisation costs for DFU during the study period ranged from US$65.87 million to US$72.16 million. All figures were inflation adjusted to 2023 US dollars.
DFU poses a significant clinical and economic burden in Singapore. Understanding the costs associated with DFU is essential for resource allocation and planning in DFU management.

BackgroundAcute pulmonary edema is a severe clinical condition with high mortality. The anion gap, reflecting metabolic acid-base disturbances, is often elevated in critically ill patients. However, its relationship with outcomes in acute pulmonary edema remains unclear.
ObjectiveTo explore the association between admission anion gap levels and 28-day all-cause mortality in patients with acute pulmonary edema.
MethodsThis retrospective cohort study utilized data from the MIMIC-IV database (2008–2019) and included adult patients with acute pulmonary edema. Patients were categorized into quartiles based on anion gap levels. Cox regression models analyzed the relationship between anion gap and mortality, with restricted cubic spline (RCS) curves, Kaplan-Meier analysis, and subgroup analyses.
ResultsA total of 1094 patients were included. Univariate Cox regression showed a positive correlation between anion gap levels and 28-day mortality (HR = 1.13, 95%CI: 1.09–1.17, P P P Conclusion
Admission anion gap levels predict 28-day all-cause mortality in acute pulmonary edema patients, particularly in younger patients and those without renal disease. Clinically, anion gap monitoring should be emphasized, and individualized prognostic and treatment strategies should be developed with factors like age and renal status to improve outcomes.
To systematically identify and appraise existing risk prediction models for EN aspiration in adult inpatients.
A systematic search was conducted across PubMed, Web of Science Core Collection, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Biomedical Literature Database (CBM) and VIP Database from inception to 1 March 2025.
Systematic review of observational studies.
Two researchers independently performed literature screening and data extraction using the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). The Prediction Model Risk of Bias Assessment Tool (PROBAST) was employed to evaluate both the risk of bias and the clinical applicability of the included models.
A total of 17 articles, encompassing 29 prediction models, were included. The incidence of aspiration was 9.45%–57.00%. Meta-analysis of high-frequency predictors identified the following significant predictors of aspiration: history of aspiration, depth of endotracheal intubation, impaired consciousness, sedation use, nutritional risk, mechanical ventilation and gastric residual volume (GRV). The area under the curve (AUC) was 0.771–0.992. Internal validation was performed in 12 studies, while both internal and external validation were conducted in 5 studies. All studies demonstrated a high risk of bias, primarily attributed to retrospective design, geographic bias (all from different parts of China), inadequate data analysis, insufficient validation strategies and lack of transparency in the research process.
Current risk prediction models for enteral nutrition-associated aspiration show moderate to high discriminative accuracy but suffer from critical methodological limitations, including retrospective design, geographic bias (all models derived from Chinese cohorts, limiting global generalisability) and inconsistent outcome definitions.
Recognising the high bias of existing models, prospective multicentre data and standardised diagnostics are needed to develop more accurate and clinically applicable predictive models for enteral nutrition malabsorption.

To evaluate the research capability of clinical nurses in China and identify the determinants associated with their capability.
As nursing evolves into an increasingly independent discipline, the research capability of clinical nurses has become critical for the development of the profession, advancing evidence-based practice and improving patient care quality.
A multicentre cross-sectional survey was conducted using convenience sampling from September 2023 to February 2024, among clinical nurses in tertiary hospitals across three provinces in China. The Nursing Research Capability Self-Assessment Scale was used to assess the research capability of the nurses. Chi-square tests, one-way analysis of variance and multiple linear regression were used to examine factors associated with research capability. The Strengthening the Reporting of Observational Studies in Epidemiology was followed.
A total of 1074 clinical nurses participated. The mean research capability score was 89.11 ± 27.69, reflecting a moderate level of research capability. However, two dimensions of research questions and literature review received lower scores. Multiple linear regression analysis identified that education level, professional title, administrative position and nursing job title (all p < 0.05) were independent predictors of research capability.
Clinical nurses exhibit moderate research capability, with notable deficiencies in formulating research questions and conducting literature reviews. Key factors influencing research capability include education, professional title, administrative position, and job title. Targeted training and development programmes should address these factors to enhance nurses' research competence and advance nursing science.
Mediastinal and/or hilar lymphadenopathy (MHL) is increasingly identified owing to various underlying conditions. Minimally invasive biopsy techniques, including endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), transbronchial mediastinal cryobiopsy (TBMC) and transbronchial forceps biopsy (TBFB), are common diagnosis tools. However, their safety and diagnostic efficiency remain unclear. This trial aims to compare the diagnostic yield and safety of these three techniques.
This study is a three-arm, parallel-design, randomised controlled trial involving 972 adult patients with MHL recruited from multiple medical centres. Participants will be randomly assigned to the EBUS-TBNA, TBMC via a tunnel or TBFB via a tunnel group. The primary outcome is diagnostic yield, and the secondary outcomes include diagnostic sensitivity, sample quality and procedure-related complications. Statistical analyses will be conducted using the appropriate methods. An independent sample ² test will be used to test the differences in the diagnostic yield and incidence of procedure-related complications.
Ethics approval was obtained from the China-Japan Friendship Hospital Ethics Committee (2022-KY-194).
Written informed consent will be obtained from all patients or their guardians before their enrolment in the study. This study will be conducted per the principles established in the Declaration of Helsinki and the International Council for Harmonisation Guidelines for Good Clinical Practice.
To conceptualise information distortion in Electronic Health Records (EHRs), with the goal of providing a theoretical foundation for improving documentation practices.
A concept analysis.
Walker and Avant's strategy for concept analysis was used. The defining attributes, antecedents and consequences were identified.
A comprehensive search was conducted across PubMed, Web of Science, Embase, CINAHL and Scopus from their inception to December 2024. Studies published in English that addressed information distortion in EHRs were included.
A total of 37 studies were included. The three defining attributes were: real-world health truth, representation of reality and mismatch relationship. Antecedents were divided into five categories: people-related factors, equipment factors, regulatory factors, working environment factors and management factors. The consequences of information distortion in EHRs included threats to patient safety, poor operational performance, eroded trust, compromised research quality and health inequity.
This concept analysis enhances the understanding of information distortion in EHRs and provides a foundation for further empirical validation. The findings may contribute to the development of measurement instruments and strategies to mitigate information distortion in healthcare settings.
By undertaking a concept analysis of information distortion in EHRs, healthcare professionals will be better equipped to recognise and assess this ethical phenomenon, thereby supporting the development of targeted interventions to mitigate potential harms to healthcare practices. In addition, the clarity of this concept could provide a new angle from which to analyse the origins of flawed EHR documentation and its ripple effects across healthcare systems.

Mental health issues such as depression and anxiety are highly and disproportionally prevalent among university students. Beyond the academic rigour, stressors imposed by a new environment result in them being vulnerable to the onset and manifestation of mental health symptomatology. Leveraging smartphones and wearables for digital phenotyping capabilities is an innovative approach for monitoring and intervening in the mental health conditions of university students. This provides a unique opportunity to collect and identify digital and behavioural biomarkers, subsequently enabling the development of predictive models to identify university students at risk.
This study—Brightline—will employ an observational study design over a 6-month period, recruiting 500 students from a major public university in Singapore. Passive data collection will occur continuously throughout the monitoring period through a wearable device (Fitbit Charge 6) and smartphone sensors via the Brightline app, which uses a digital phenotyping data collection platform. Active data collection will consist of self-report questionnaires to be completed at the beginning of the study and follow-up assessments at 1, 3 and 6 months after. The passive and active data collected will be analysed to identify the digital biomarkers associated with depression, anxiety, stress, loneliness and affect among university students. Predictive models of these mental health issues will also be developed.
This study was approved by the Nanyang Technological University Institutional Review Board (IRB-2023-894). Findings from this study will be published in peer-reviewed journals and presented at academic conferences.

Psychiatric nurses represent a high-stress occupational group that experiences elevated levels of suicidal ideation (SI), emphasizing the need for focused mental health interventions. The main purpose of this study was to examine the prevalence of SI among psychiatric nurses and to identify the psychological and occupational factors associated with SI. A total of 1,835 psychiatric nurses completed questionnaires on depressive symptoms (PHQ-9), SI, quality of work-related life (QWL), and burnout. Multivariate logistic regression and phenotypic network analyses were conducted to identify factors associated with SI and the potential pathways linking depressive symptoms, burnout, and QWL to SI. The results indicated that 11.33% of the participants had SI in the past two weeks. Multivariate logistic regression revealed that emotional exhaustion, depersonalization, personal accomplishment, stress at work, general well-being, and the home-work interface were significant predictors of SI. Network analysis further revealed that psychomotor changes, guilt, sad mood, low energy, and appetite changes were the symptoms most directly associated with SI. In addition, sad mood, general well-being, and work-home interface were linked to job and career satisfaction, whereas sad mood and low energy were associated with emotional exhaustion and SI. These findings contribute valuable large-scale evidence on the mental health challenges faced by psychiatric nurses and highlight the importance of addressing mood disturbances, energy loss, and work-related stress in SI prevention efforts for this vulnerable group.by Chean Tat Chong, Lalitha Palaniveloo, Sulhariza Husni Zain, Muhamad Khairul Nazrin Khalil, Kishwen Kanna Yoga Ratnam
Gestational diabetes mellitus (GDM) is a growing public health concern, particularly among women with advanced maternal age. Understanding the prevalence and associated sociodemographic factors is crucial for targeted interventions. This study aimed to determine the prevalence of GDM and its association with sociodemographic factors among Malaysian women with advanced maternal age. This study utilized data from the National Health and Morbidity Survey 2022: Maternal and Child Health, a nationwide cross-sectional survey employing a two-stage stratified cluster sampling design. GDM was identified based on the result of a modified oral glucose tolerance test (MOGTT) recorded in the mother’s antenatal book. The 75-g MOGTT was performed according to the Clinical Practice Guidelines for the Management of Diabetes in Pregnancy in Malaysia. Sociodemographic variables, including ethnicity, locality, education, employment, and household income, were analysed. Multiple logistic regression was performed to identify factors associated with GDM. The prevalence of GDM among women with advanced maternal age in Malaysia was 33.7% (95% CI: 30.9%−36.5%). Ethnicity was significantly associated with GDM, with Indian women showing the highest prevalence (48.8%) and odds (AOR: 7.31, 95% CI: 2.58–20.72; Pby Ruilan Lin, Ru Qin, Yunlong Zhang, Yao Guan, Boheng Wu, Shangyang Li, Shenhong Qu, Yulin Yuan
BackgroundThis study aims to assess the diagnostic value of the Epstein-Barr virus (EBV) BNLF2b antibody(P85-Ab), alone or in combination with VCA-IgA, Rta-IgG, and Zta-IgA antibodies, in the context of nasopharyngeal carcinoma (NPC).
MethodsThe study included 100 NPC patients and 100 healthy controls. Chemiluminescent microparticle immunoassay was utilized to measure P85-Ab levels in the serum samples of both NPC patients and healthy controls. Additionally, the ELISA method was employed to detect serum levels of VCA-IgA, Rta-IgG, and Zta-IgA antibodies. The study analyzed the roles of serum P85-Ab in conjunction with VCA-IgA, Rta-IgG, and Zta-IgA antibodies in the diagnosis of NPC.
ResultsSerum levels of P85-Ab, VCA-IgA, Rta-IgG, and Zta-IgA antibodies in NPC patients were significantly higher than those in the normal control group (P Conclusion
The combined detection of P85-Ab with VCA-IgA, Rta-IgG, and Zta-IgA antibodies demonstrates high diagnostic value for nasopharyngeal carcinoma. Serum P85-Ab may serve as a potential marker for the diagnosis of NPC.

This study aimed to determine the association between diabetes mellitus (DM) medication use and glycaemic control.
This was a retrospective diabetes registry-based cohort study.
Singapore.
Patients aged 18 and above with incident DM in the SingHealth Diabetes Registry from 2013 to 2020 were included. The entire study period included a 1 year baseline period, a 1 year observation period and a 3 month outcome period.
Drug use was measured using the proportion of days covered (PDC), and the changes in glycated haemoglobin (HbA1c) between the outcome and baseline periods were assessed. The associations between baseline HbA1c and PDC ≥0.80 and between PDC and change in HbA1c were analysed using logistic regression and the Kruskal–Wallis test, respectively.
Of 184 646 unique patients in the registry from 2013 to 2020, 36 314 met the inclusion and exclusion criteria and were included in the analysis. The median PDC for any DM drug, oral DM drugs and insulin during the observation period was 20.3%, 16.8% and 0%, respectively. Those who had good glycaemic control at baseline were less likely to receive DM drugs and those with poor baseline glycaemic control or missing baseline HbA1c were more likely to be consistent users (PDC >80%) (px 10-16).
The relationship between DM drug use and glycaemic control is complex and non-monotonic. Higher PDC for any DM drug and oral DM drugs during the observation period was significantly associated with clinically relevant HbA1c improvements.

This study aimed to investigate the effects of dietary chitosan oligosaccharide (COS) supplementation on growth performance, antioxidant capacity, immune function, duodenal digestive enzyme activity, and jejunal morphology in growing female minks. Ninety-six 12-week-old minks were randomly assigned to six groups (0, 100, 200, 300, 400, or 500 mg/kg COS), with 8 replicates per treatment and 2 minks per replicate, for an 8-week trial. The results showed that average daily gain (ADG) increased quadratically with increasing COS levels (P P P P P PIn the era of ‘Undetectable = Untransmittable’ (U=U), reductions in condom use and increases in casual partnerships may contribute to elevated risks of coinfection with other sexually transmitted infections (STIs) and HIV super-infections among men living with HIV. These trends may reflect a shift in personal attitudes towards sexual behaviour and HIV risk, yet their influence on actual behaviours remains unclear.
To investigate how changes in personal attitudes and safe sex self-efficacy influence sexual decision-making.
Two-wave longitudinal study design.
We conducted a 3-month longitudinal study from March to December 2023 among HIV-positive men (≥ 18 years) initiating ART in Changsha, China. Cross-lagged panel analysis and half-longitudinal mediation analysis were used to examine how changes in personal attitudes influenced sexual behaviours.
427 men living with HIV were included at baseline, and 301 completed the follow-up survey. Sexual behaviours were associated with personal attitudes, namely safe sex fatigue, viral load/transmission beliefs, and sexual sensation seeking. More positive personal attitudes in these domains at baseline predicted lower safe sex self-efficacy over 3 months, while reduced baseline self-efficacy increased the likelihood of engaging in condomless sex and/or multiple sexual partners. All three personal attitude domains had significant indirect effects on sexual behaviours via safe sex self-efficacy.
In the era of U=U, the changed personal attitudes among men living with HIV may lead to the increased likelihood of engaging in condomless sex and/or having multiple sexual partners, and safe sex self-efficacy serves as a mediator in this relationship.
This study highlights the potential influence of attitudinal changes on sexual behaviours among men living with HIV in the ‘U=U’ era. Findings provide valuable evidence for developing more targeted interventions that address not only behavioural outcomes but also underlying personal attitudes.

Glaucoma is the second leading cause of moderate to severe visual impairment worldwide, primarily affecting peripheral vision and increasing the risk of falls due to impaired balance and mobility. While traditional physical training (PT) is used for fall prevention, its effectiveness may be limited by low patient engagement. Action video games (AVGs) may offer a more engaging alternative for improving balance and mobility in individuals with glaucoma.
This prospective, two-arm, single-blind, active-control trial will involve 56 patients with glaucoma with moderate to severe peripheral field loss and intact cognitive function, who have not previously undergone balance training. Participants will be randomly assigned in a 1:1 ratio to either a physically interactive action video-game training (AVG) group or a conventional PT group. The AVG group will use a Nintendo Switch gaming station for 20 sessions of 45 min each, conducted two to three sessions per week over 8 weeks. These sessions will involve standing game exercises using game controllers or body sensors, focusing on muscle stretching and strengthening, balance improvement and fitness. The PT group will engage in traditional PT for the same duration and frequency. The primary outcome is the change in mobility function after 20 sessions, measured by the narrow path walking test. Secondary outcomes include balance function (modified Clinical Test of Sensory Interaction and Balance, motor control test, landing balance test, five-time sit-to-stand test and time up and go test), visual cognition (reaction time test and useful field of view test) and patient-reported outcomes (validated questionnaires). Exploratory outcomes include fall frequency, fear of falling, visual function and serum brain-derived neurotrophic factor levels (one of the biomarkers related to exercise). Assessments will occur at seven time points: baseline (T1), after 10 sessions (T2), after 20 sessions (T3), 1-month post-training (T4) and 3, 6 and 9 months after all training sessions (T5–T7).
The human ethics approval was obtained from the respective ethics board of the Hong Kong Polytechnic University (ID: HSEARS20210722001). The study protocol will conform to the principles of the Declaration of Helsinki. Results will be disseminated through peer-reviewed journals and conferences.
