Loneliness and social isolation are critical public health issues linked to significant adverse health outcomes and increased healthcare utilisation, including visits to the emergency department (ED). The ED often serves as a primary societal safety net, providing care for vulnerable populations who may be disproportionately affected by these conditions. In fact, loneliness and social isolation might be the underlying reasons they presented to the ED in the first place either consciously or not. For such individuals, the ED encounter may represent a rare point of human contact, yet the stressful and depersonalising nature of the ED environment may paradoxically exacerbate their sense of isolation. Furthermore, ED staff may lack the training and awareness of the scope of the problem to properly screen for loneliness and address it. Yet, the compounded impact of the ED experience on lonely or socially isolated patients and the relationship between loneliness and healthcare utilisation remains poorly understood. This paper presents a protocol for a scoping review designed to systematically map the existing evidence on the experiences of these patients and the perspectives of the clinicians who care for them.

This scoping review will be conducted following the Arksey and O’Malley methodological framework in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The findings will be reported according to the Extension to the PRISMA Statement for Reporting Literature Searches in Systematic Reviews (PRISMA-S; see ). A comprehensive search will be performed across five electronic databases (PubMed, Embase, Scopus, Web of Science, CNKI) and grey literature sources. Studies published in English or Chinese that address loneliness or social isolation in the ED context, from the perspective of adult or paediatric patients or clinical staff, will be included. A novel, artificial intelligence (AI)-assisted screening process will be utilised for initial relevance assessment, followed by full manual screening and data extraction by two independent reviewers to ensure rigour and mitigate bias. Findings will be synthesised using a narrative approach and thematic analysis to identify key concepts, themes and existing gaps in the literature.

As this study synthesises data from previously published literature, it does not require formal ethical approval. The findings will be disseminated through a manuscript submitted to a peer-reviewed, open-access journal. The aim is to provide an evidence-based roadmap to guide future research, inform policy and support the development of interventions designed to improve care and outcomes for this vulnerable population within the acute care setting.

To identify subgroups with similar social determinants of health (SDOH) characteristics using latent class analysis (LCA) and examine their associations with physical and mental health, cognitive function and missed workdays at 3 and 6 months post-SARS-CoV-2 infection. We hypothesised that intersecting SDOH factors would differentially influence COVID-19-related health outcomes across subgroups.

Prospective cohort study from the Innovative Support for Patients with SARS-CoV-2 Infections Registry (INSPIRE), with longitudinal data collection and cross-sectional analyses at baseline, 3-month and 6-month follow-ups.

Multicentre registry across eight US academic medical centres (Chicago, Dallas, Houston, Los Angeles, New Haven, Philadelphia, San Francisco and Seattle).

Adults aged ≥18 years, fluent in English or Spanish, with self-reported acute COVID-19 symptoms and a confirmed positive SARS-CoV-2 test within 42 days before enrolment (9 December 2020 to 12 August 2022), and access to an internet-connected device. Exclusions included incarceration, inability to provide informed consent, lack of confirmed SARS-CoV-2 infection or no internet access. Of 3791 eligible participants with complete baseline data, 2897 (76.4%) completed the 3-month follow-up and 2666 (70.3%) completed the 6-month follow-up; most were aged 18–49 years (74–75%), female (66–67%), white (86.6–87.5%) and non-Hispanic (86.6–87.5%).

Prespecified primary outcomes were physical and mental health (Patient-Reported Outcomes Measurement Information System (PROMIS)-29 V.2.1 T-scores for depression, anxiety, fatigue, sleep disturbance, pain interference, physical function and social participation), cognitive function (PROMIS Cognitive Function Short Form 8 T-scores) and missed workdays due to illness (binary: >1 week vs ≤1 week, from a single-item survey). All measures were self-reported and collected at baseline, 3 months and 6 months; no changes from protocol.

LCA identified a 4-class model as optimal (lowest Bayesian Information Criterion (BIC) after evaluating 1–7 class models; significant demographic differences (² p

In this US prospective cohort, SDOH-based subgroups showed persistent disparities in health outcomes post-SARS-CoV-2 infection. Findings highlight the urgent need for intersectional approaches to address systemic inequities in post-COVID-19 recovery.

To investigate the prevalence of depression, anxiety and stress among primary caregivers of children with childhood-onset systemic lupus erythematosus (cSLE) in China and to explore their psychosocial correlates based on the stress process model.

A cross-sectional study.

3 tertiary public hospitals in Hunan Province, China.

242 primary caregivers were invited, and 211 completed the study (87.2% response rate). Convenience sampling was used. Eligible participants were unpaid adult caregivers (aged ≥18 years) of children (aged 1 month. Exclusion criteria included inability to complete questionnaires independently, cognitive impairment due to major physical or mental disorders and current participation in other psychological interventions.

Primary outcomes (depression, anxiety and stress) were measured using the Depression Anxiety and Stress Scale-21. Correlates included threat/challenge appraisal, coping style and perceived social support.

Among 211 caregivers (mean age 40.55±8.22 years; 77.3% female), 31.8% reported depression, 27.0% anxiety and 24.2% stress. Higher threat appraisal was consistently associated with depression (regression coefficients (B) =1.012, p

Caregivers of children with cSLE face substantial psychological distress, with threat perception and negative coping as key modifiable correlates. Interventions to reshape cognitive appraisal and promote adaptive coping, alongside expanded health insurance coverage and optimised caregiving role distribution, are needed to alleviate caregiver burden.

The progressive adaptation of the maternal cardiovascular system throughout pregnancy is essential to maintaining adequate uteroplacental circulation and meeting maternal physiological demands. In recent years, maternal haemodynamic parameters have gained attention as useful indicators for screening and managing pregnancy, particularly for identifying women at high risk for complications and predicting adverse pregnancy outcomes. The aim of this study is to assess the trajectory of haemodynamic parameters during labour, establish reference ranges for different stages of labour and explore the association between haemodynamics and adverse pregnancy outcomes.

This is an ambispective observational cohort study conducted in a tertiary hospital in Chongqing, China. A total of 2800 pregnant women will be enrolled. After hospital admission and providing written informed consent, participants will complete a demographic questionnaire. Data collection will include maternal baseline characteristics, haemodynamic parameters at multiple stages of labour and maternal and newborn outcomes. These data will allow comprehensive analysis of haemodynamic changes during labour in women undergoing vaginal delivery.

This study has been approved by the Research Ethics Committee of the First Affiliated Hospital of Chongqing Medical University (ethics approval number: 2024–406-01). Participation is voluntary and initiated only after obtaining written informed consent. The findings will be disseminated through presentations at national and international conferences and through publications in peer-reviewed scientific journals.

This study aimed to identify a deterioration prediction tool for patients after craniotomy.

A retrospective cohort study.

Three large tertiary hospitals in Hunan Province, China.

Between January 2018 and March 2020, 1576 patients who underwent craniotomy at three tertiary hospitals in Hunan Province were selected and randomly allocated to either the training or validation sets at a 7:3 ratio. Comprehensive demographic and disease-specific data were collected. Logistic regression, Bayes classification and back propagation neural network were used to construct the models. The Technique for Order Preference by Similarity to an Ideal Solution method was used to evaluate the efficiency of the models.

The performance of all three models was commendable. In both the training and validation datasets, the back propagation neural network model demonstrated the highest efficiency, achieving a sensitivity of 77.1%, specificity of 91.7%, correctness of 86.8%, positive predictive value of 82.3% and negative predictive value of 88.9%. Conversely, the Bayes classifier exhibited the lowest predictive efficiency among the models evaluated.

We developed three models to predict clinical deterioration in patients following craniotomy. Among these, the back propagation neural network model demonstrated superior predictive performance. This model serves as a valuable reference for clinical nurses, aiding them in identifying high-risk patients who may deteriorate post-craniotomy.

Adolescent idiopathic scoliosis (AIS) requires long-term conservative management to prevent curve progression. While physiotherapeutic scoliosis-specific exercises, specifically the Schroth method, are considered the gold standard for conservative treatment, their clinical efficacy is often limited by accessibility barriers, high costs and suboptimal treatment adherence. This study aims to evaluate the efficacy of a novel artificial intelligence (AI)-based digital therapeutic system, which uses computer vision for remote, personalised posture analysis and adaptive exercise prescription compared with traditional outpatient Schroth therapy.

This parallel-group randomised controlled trial will be conducted at Guangzhou Women and Children’s Medical Center (Guangzhou, China). 300 adolescents aged 10–18 years with AIS who present with a Cobb angle between 10° and 30° and a Risser sign of 0–2 will be recruited and randomised in a 1:1 ratio into an intervention group and a control group. The intervention group will use a smartphone application to capture standardised bi-weekly images. These images will be processed by an AI algorithm to classify curve patterns and assign personalised exercise modules with adaptive dosing ranging from maintenance to high-intensity levels. The control group will receive standard outpatient Schroth care. The primary outcome is the absolute change in the major curve Cobb angle from baseline to 6 months. Secondary outcomes include the angle of trunk rotation, trunk appearance perception, Scoliosis Research Society-22 Revised (SRS-22r) quality-of-life scores and adherence rates. Statistical analysis will follow the intention-to-treat principle using linear mixed models to account for repeated measures.

Ethical approval has been obtained from the Medical Ethics Committee of Guangzhou Women and Children’s Medical Center (Guangzhou, China) (approval no. [2025]497A01). Written informed assent and consent will be obtained from participants and their legal guardians respectively. Results will be disseminated through peer-reviewed journals and international conferences.

Adequate sedation is essential for paediatric patients undergoing invasive haematologic-oncologic procedures. The combination of propofol and remifentanil is commonly used yet is associated with respiratory depression. Esketamine has anaesthetic, analgesic and sympathomimetic properties and is known to cause less respiratory depression than other sedatives. This study aims to assess esketamine versus remifentanil in combination with propofol for invasive haematological-oncological procedures for paediatric patients.

This prospective, randomised, double-blind, two-period crossover trial will include 80 paediatric patients aged 6–12 years, with American Society of Anesthesiologists Physical Status II to III, who are scheduled to undergo repeated invasive procedures including bone marrow aspirates and lumbar punctures under sedation. Participants will be randomised to two sequences: AB or BA. In sequence AB, children will receive propofol (3 mg/kg) and esketamine (0.5 mg/kg) in period 1 and propofol (3 mg/kg) and remifentanil (1 µg/kg) in period 2. In sequence BA, the order is reversed. The primary endpoint of this trial is the incidence of desaturation events, defined as SpO₂

The trial was approved by the Ethics Committee of the Children’s Hospital of Soochow University (Approval No. 2025008). The results of this trial will be submitted for peer review and publication in a scientific journal.

Remimazolam, an ultra-short-acting benzodiazepine, is characterised by rapid onset and recovery, metabolism independent of hepatic or renal function and haemostability. Despite the above pharmacokinetic (PK) advantages and potential benefits for renal- or hepatic-insufficient patients and the elderly patients, the effects and population pharmacokinetics–pharmacodynamics (popPK/PD) of remimazolam for general anaesthesia in elderly, hepatic or renal insufficient patients from large, randomised controlled trials remain unknown.

This is a randomised controlled single-blind multicentre study. Patients undergoing selective surgeries (eg, abdominal, orthopaedic or urologic procedures) will be screened and randomised into the elderly (age ≥65 years), hepatic insufficiency (Child-Pugh class B or C) or renal insufficiency (estimated glomerular filtration rate

Tinnitus is a highly prevalent and distressing symptom in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). While international clinical guidelines primarily focus on hearing recovery through pharmacological interventions, effective treatment for tinnitus remains limited. Sound therapy, such as masking and retraining therapy, has emerged as a promising treatment. This systematic review aims to evaluate the efficacy and safety of sound therapy for the alleviation of tinnitus in adult patients with ISSNHL.

Researchers will independently conduct searches for randomised controlled trials in the following databases: PubMed, Embase, Cochrane Library, Web of Science, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP), CNKI and Wanfang Data. The literature search is scheduled for March 2026 without language restrictions. The review will include studies involving adult patients (18 years or older) diagnosed with ISSNHL with tinnitus symptoms who underwent sound therapy (including Tinnitus Masking Therapy, Tinnitus Retraining Therapy or music therapy) with standard drug therapy, placebo or any other non-acoustic interventions compared with the same treatment alone. Researchers will independently screen studies, extract data and assess the risk of bias using the Cochrane Risk of Bias 2 tool. Data analyses will be performed using RevMan V.10.0.2 and Stata V.18.0 software. The certainty of the evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

This study relies on the analysis of secondary data from previously published trials; therefore, ethical approval from a research ethics committee is not required. The results of this systematic review will be disseminated through publication in a peer-reviewed scientific journal.

The predominant concern during pregnancy is musculoskeletal pain, often accompanied by additional discomforts such as anxiety and insomnia. Pilates, as a low-impact mind-body exercise, may be beneficial in managing musculoskeletal pain and associated symptoms in adults. This systematic review and meta-analysis aimed to synthesise the evidence on the effectiveness of Pilates for alleviating musculoskeletal pain and other discomforts during pregnancy.

Systematic review and meta-analysis.

PubMed, Scopus, TRIP Medical Database, Web of Science and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched from inception to 14 January 2026.

Randomised controlled trials and prospective non-randomised controlled studies that compared Pilates with other prenatal care modalities for improving musculoskeletal pain and discomfort were eligible.

Two researchers independently extracted data using standardised forms with subsequent cross-verification. Risk of bias was assessed using the Cochrane Risk of Bias V.2.0 tool. Meta-analyses were performed using random-effects models. The certainty of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach.

13 studies were included in the systematic review, of which 10 contributed data to the meta-analysis. Primary outcomes were pain intensity and disability level. Pain intensity was assessed using Visual Analogue Scale (range 0–10). Moderate-certainty evidence demonstrated that Pilates significantly reduced musculoskeletal pain during pregnancy (mean differences (MD)=–2.59, 95% CI –4.19 to –1.00; I^²=91%, p=0.001). Low-certainty evidence suggested that Pilates reduced pregnancy-related disability (standardised mean differences (SMD)=–1.82, 95% CI –2.99 to –0.66; I^² = 93%, p=0.002). Secondary outcomes comprised sleep quality and psychological status. Multivariate meta-analysis showed significant improvements in psychological status (SMD=–0.86, 95% CI –1.31 to –0.42; ²=0.4, I^²=86%, p=0.0005) but did not yield statistically significant improvements in sleep quality (MD=–1.93, 95% CI –4.70 to 0.84; I^²=93%, p=0.17). Both secondary outcomes were supported by very low-certainty evidence. Risk of bias assessment rated three studies as high risk, three as unclear risk and seven as low risk. Formal assessment of publication bias was not feasible owing to the limited number of studies (fewer than 10 per outcome).

This meta-analysis demonstrates that, compared with standard care, structured prenatal Pilates significantly alleviates musculoskeletal pain and disability while also enhancing psychological status.

Tobacco use is a major contributor to the burden of chronic obstructive pulmonary disease (COPD) and other non-communicable diseases in China. People at high risk for COPD who smoke, particularly those with pre-existing chronic conditions, often remain underserved by conventional smoking cessation programmes. Population medicine offers a promising framework for proactively identifying high-burden diseases, managing multimorbidity and prioritising interventions for vulnerable populations.

This protocol describes a stratified, two-arm cluster randomised controlled trial (Population Medicine Multimorbidity Intervention in Xishui County-Smoking) being conducted in Xishui County, a rural area of Guizhou Province, China. A total of 26 townships were stratified by population size and randomly assigned in a 1:1 ratio to receive either a multicomponent intervention or usual care. Eligible participants were individuals aged 35 years or older who smoked and were at high risk for COPD as identified by the COPD Screening Questionnaire. The intervention package integrates multiple components, including a digital smoking cessation programme, digital mental health support, community-based spirometry, tailored chronic disease management, health education and a performance-linked ‘pay-for-population’ scheme that aligns healthcare worker reimbursement with population health outcomes. Primary outcomes are smoking amount and nicotine dependence and secondary outcomes include COPD-related health outcomes, hypertension, diabetes, health risk behaviours, quality of life, healthcare utilisation and productivity loss. Follow-up occurs at 3, 6 and 12 months.

Ethical approval has been granted by the Peking Union Medical College Ethics Committee (CAMS&PUMC-IEC-2024-042). Informed consent was obtained from all participants prior to enrolment. Results will be shared through peer-reviewed publication and (inter)national conference presentations.

This real-world study investigated the changes of lipid lowering therapy (LLT) usage in patients with high or very high cardiovascular (CV) risk in the UK and the group of all other European countries in the SANTORINI study up to 1 year from baseline and the impact this treatment had on the attainment of low-density lipoprotein cholesterol (LDL-C) risk-adjusted goals set by the National Institute for Health and Care Excellence (NICE) and those in the 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) dyslipidaemia guidelines.

Secondary analysis of the SANTORINI dataset (an international, prospective, observational, non-interventional study (NCT04271280)).

Primary and secondary care centres in the UK and the group of other European countries (Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Portugal, Spain, Sweden and Switzerland).

663 UK patients with high and very high CV risk were included in this analysis and 8502 from the group of other European countries. Of these, 380 UK patients and 6830 from the group of other European countries had LDL-C information available at baseline and 1-year follow-up.

The primary objectives were to describe patients’ lipid management, LDL-C levels at 1-year follow-up and their attainment of 2023 NICE (≤2.0 mmol/L) and 2019 ESC/EAS LDL-C 2019 guideline-recommended LDL-C goals (

Over the course of 1-year follow-up, the overall proportion of UK patients on no LLT reduced from 20.4% at baseline to 7.1%, similar to that observed in the group of other European countries (baseline–20.9%, 1 year–3.0%). The proportion of UK patients receiving LLT monotherapy increased from 74.8% at baseline to 84.9%, higher at both time points than that observed for the group of other European countries (baseline: 52.0%, 1 year: 55.0%). The use of any combination therapy increased slightly from baseline to 1 year in the UK overall cohort (4.9% vs 7.1%) and overall in the group of all other European countries, the cohort increased from baseline (27.1%) to 1 year (40.2%). Overall, mean (SD) LDL-C levels in the UK were 2.5 (1.2) mmol/L at baseline and 2.1 (1.0) mmol/L at 1 year and for the group of other European countries were 2.4 (1.2) mmol/L at baseline and 2.0 (0.9) mmol/L at 1 year. The overall proportions of UK patients achieving the UK NICE treatment goal and ESC/EAS 2019 guidelines at baseline versus 1-year follow-up were 40.3% vs 52.6% and 22.9% vs 32.9%, respectively; 21.1% and 30.9% of patients in the group of other European countries achieved the ESC/EAS 2019 guidelines at baseline and 1-year follow-up, respectively.

In this UK-focused analysis of the SANTORINI study, use of LLT increased modestly over 1 year, accompanied by a reduction in average LDL-C levels. However, mean LDL-C remained above the NICE goal, and attainment of both NICE and ESC/EAS LDL-C thresholds remained suboptimal. The findings highlight continued opportunities to optimise lipid management in UK clinical practice, including the potential for broader use of combination therapies.

To evaluate the effects of nurse-led shared decision-making (SDM) on lung cancer screening outcomes, including low-dose CT (LDCT) uptake, benign findings, early cancer detection and willingness to participate among high-risk populations.

Systematic review and meta-analysis.

PubMed, Medline via OvidSP, Cochrane Central Register of Controlled Trials, EMBASE via OvidSP, Web of Science, Scopus, grey literature databases and clinical trial registries were searched from inception to March 2025.

Studies evaluating nurse-led SDM interventions in high-risk lung cancer populations, reporting outcomes including LDCT uptake rates, screening results (Lung-RADS (Lung Imaging Reporting and Data System) classifications), early-stage cancer detection or willingness to participate. Randomised controlled trials, quasi-experimental studies and observational studies were included.

Two reviewers independently extracted data and assessed risk of bias using the Risk of Bias in Non-randomised Studies of Interventions (for non-randomised studies) and Cochrane Risk of Bias 2.0 (for randomised controlled trials). Meta-analyses were conducted using random-effects models. Meta-regression explored sources of heterogeneity.

13 studies (n=13 608 participants) were included, comprising 10 single-arm studies and three comparative studies. In single-arm studies without control groups, nurse-led SDM programmes achieved a pooled LDCT uptake rate of 98% (95% CI 28% to 100%; I²=99%), and willingness to participate was 68% (95% CI 24% to 93%; I²=98%). In comparative studies, nurse-led SDM showed no significant difference in LDCT uptake compared with usual care (RR 1.00, 95% CI 0.99 to 1.02; I²=0%), suggesting non-inferiority rather than superiority. Among individuals who completed screening, 81% (95% CI 77% to 85%) had benign or low-risk findings (Lung-RADS [Lung Imaging Reporting and Data System] I/II), and 2% (95% CI 1% to 3%) were diagnosed with early-stage lung cancer, rates consistent with benchmark screening trials. Meta-regression identified female sex as positively associated with uptake (β=0.54, p

Comparative evidence suggests that nurse-led SDM achieves equivalent LDCT uptake to standard care approaches, indicating feasibility as an alternative service delivery model. However, the predominance of single-arm studies, high heterogeneity and moderate-to-serious risk of bias limit causal inference. High uptake rates in single-arm studies likely reflect selection bias rather than intervention effectiveness. Current evidence supports the feasibility but not the superiority of nurse-led SDM. Well-designed randomised controlled trials are needed to establish comparative effectiveness and cost-effectiveness before recommending widespread integration of nurse-led SDM into lung cancer screening programmes.

Metabolic syndrome (MetS) poses a significant public health challenge among employed adults. Lifestyle modifications have been shown to be effective in preventing the onset and progression of MetS in employed adults, and the widespread adoption of mobile and wearable technologies introduces an appealing approach to mHealth lifestyle interventions. When widely implementing smartphone-based interventions for employed adults, enhancing equitable access and promoting wearable device use for those with MetS is a more cost-effective way to reduce health disparities, particularly in resource-limited settings. However, relevant evidence is currently lacking.

This study aims to design an mHealth-based Healthy Lifestyle Promotion (MYLIFE) trial, a three-arm randomised controlled trial (RCT), to evaluate the effectiveness of a smartphone-based lifestyle intervention and a combined smartphone-based lifestyle intervention with intensive intervention for MetS individuals using wearable devices, in reducing MetS risk among employed adults.

This is a three-arm, parallel, single-blind, cluster RCT with a 12-week intervention and a total follow-up of 1 year. The trial will recruit 120 workplaces from the Chinese Cohort of Working Adults in a 1:1:1 ratio to either a control group or one of two intervention groups. Within these workplaces, a total of at least 348 eligible participants will be enrolled. The regular mHealth group will receive smartphone-based intervention. The intensive mHealth group will receive smartphone-based intervention for all participants, and an additional wearable device-intensive intervention for those with MetS. The primary outcome is the Chinese MetS Z score at 12 weeks. Secondary outcomes include MetS Z score, prevalence of MetS, specific MetS components, questionnaire-based indicators, and clinical outcomes at 12 weeks and 1 years. The main analysis will follow the intention-to-treat principle, using mixed-effects models to assess between-group differences in outcomes.

The protocol has been approved by the Ethics Committee of the West China School of Public Health and the West China Fourth Hospital, Sichuan University (Gwll2025024). The findings will be published in peer-reviewed journals and presented at scientific conferences.
