Despite the minimally invasive nature of video-assisted thoracoscopic surgery (VATS), moderate-to-severe postoperative pain remains frequent and impairs recovery. Intravenous lidocaine possesses multimodal analgesic, antihyperalgesic and anti-inflammatory properties that may improve pain control and functional outcomes, but robust evidence in thoracic surgery is lacking. Moreover, its potential to attenuate neuropathic pain, a key component of chronic post-thoracic pain syndromes, has not been adequately investigated. This trial will determine whether continuous perioperative intravenous lidocaine infusion improves recovery, reduces acute pain intensity and prevents the development of neuropathic pain after VATS.

This single-centre, randomised, double-blind, placebo-controlled trial will enrol 84 adult patients undergoing elective VATS. Participants will be randomised (1:1) to receive either intravenous lidocaine (bolus 1 mg/kg at induction followed by continuous infusion at 1.5 mg/kg/hour intraoperatively and postoperatively for 24 hours) or matched normal saline postoperatively, with identical intraoperative management in both groups. The primary outcome is the incidence of moderate-to-severe movement-evoked pain at 24 hours postoperatively. Secondary outcomes include pain at 48 and 72 hours, opioid consumption, pulmonary complications, sleep quality, quality of recovery, neurocognitive outcomes and chronic neuropathic pain at 3 months. Analyses will follow the intention-to-treat principle.

The study protocol was approved by the Institutional Review Board of Tongji Hospital (Reference No. TJ-IRB202509102) and registered in the Chinese Clinical Trial Registry (ChiCTR2500111163). Written informed consent will be obtained from all participants. Results will be submitted to peer-reviewed journals and academic conferences.

To explore the impact of multiple long-term conditions (MTLCs) and a comorbid mental health condition on decision-making processes, attendance and engagement in NHS community-based therapy groups.

Qualitative in-depth interviews analysed using reflexive codebook analysis as part of a study within a trial.

Secondary community mental health teams from two UK sites.

Purposive sample of 20 participants recruited to a randomised controlled trial of group therapies (arts therapies and counselling) holding a mental health diagnosis and self-reported as having at least one additional physical health condition.

Six themes were constructed: (1) MLTCs influenced arts modality choices and goals; (2) importance of planning ahead to be organised; (3) the journey loomed over participants; (4) the impact of MLTCs on group attendance and participation; (5) the group was valued and important; (6) determination and fighting to get what I need.

Decisions about arts modalities and group attendance were based on a self-perceived level of felt capability. It was important for participants to plan in advance and feel informed ahead of making commitments, enabling them to prepare and manage symptoms. Travelling to the groups was dreaded, and many participants required support with travel in order to attend. Managing symptoms during the journey and groups was challenging; however, participants had a strong determination to uphold the commitment to attend despite their difficulties, as the group was highly valued.

MLTCs have a large impact on people’s capacity to engage in community groups, requiring additional planning and effort. The scale of this impact is often not recognised. Despite this, the benefits of groups for people with MLTCs are especially important, including motivation to leave the house, opportunities for socialisation and a means of reaching one’s own goals. Clinicians are recommended to accommodate the needs of MLTCs when designing community group interventions and consider multiple attendees with MLTCs in the group composition to improve attendance and group engagement.

Peritoneal dialysis (PD) is a widely used renal replacement therapy for chronic kidney disease patients, yet malnutrition remains a common complication linked to poor outcomes. Nearly 40% of PD patients in China are malnourished, with serum albumin levels below 35 g/L. Amino acid-based peritoneal dialysis solutions (AA-PDS), which replace glucose with amino acids as the osmotic agent, have been used globally for decades to improve nutrition and reduce peritoneal damage, but they were introduced to mainland China only in 2022. This study aims to evaluate the efficacy and safety of AA-PDS in improving nutritional status and clinical outcomes among malnourished PD patients in mainland China, providing a potential new therapeutic option for this population.

This multicentre, open-label, prospective, parallel-controlled study will enrol patients with end-stage kidney disease who were stable on PD for more than 3 months. A total of 500 eligible patients will be divided into the intervention group undergoing PD once every morning using 2.0 L of amino acid (15) PD solution and the control group using conventional PD solution (lactate) in a 4:1 ratio based on their willingness and clinical needs. Our primary outcome is serum albumin, while other nutritional indicators, including serum prealbumin, serum transferrin, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and ultrafiltration volumes are considered secondary outcomes. Information such as demographics, clinical and biochemical characteristics, examination indicators, anthropometry measurements and Subjective Global Assessment scores will be collected at baseline, 1 month, 3 month and 6 month follow-up. Statistical analysis will be conducted using SAS V.9.4 or higher versions. All statistical tests are conducted through the two-tailed test, and a p value≤0.05 will be considered statistically significant. The description of quantitative indicators will be used in calculating the number of cases, mean, SD, median and IQR method. The classification indicators will be used to describe the number of cases and percentages (frequency and frequency rate).

This multicentre study obtained ethical approval from the lead ethics committee at the First Affiliated Hospital of Zhejiang Chinese Medical University (approval no.: 2024-KLS-379-02). Additionally, each participating site provided local ethical approval or a formal waiver, as required by their institutional policies. The results will be reported in a peer-reviewed journal and a relevant academic conference.

To investigate the associations of oxidative balance score (OBS) with all-cause mortality, cardiovascular mortality and cardiovascular disease (CVD) incidence in two large, population-based cohorts.

Cohort study and cross-sectional study were used.

The US National Health and Nutrition Examination Survey (NHANES) and the UK Biobank.

A total of 33 566 adults from NHANES (1998–2018) and 55 760 adults from the UK Biobank were included.

All-cause mortality, cardiovascular mortality and CVD. Mortality outcomes were ascertained through national death registries. Prevalent CVD was identified in NHANES through questionnaire, and incident CVD events were identified in the UK Biobank using linked hospital admission and death registry data.

Higher OBS was consistently associated with lower all-cause and cardiovascular mortality in both cohorts. In NHANES, participants in the highest OBS quartile (Q4) had a 39% lower risk of all-cause mortality (adjusted HR: 0.61, 95% CI 0.52 to 0.72) and a 45% lower risk of cardiovascular mortality (adjusted HR: 0.55, 95% CI 0.41 to 0.74) compared with those in Q1. Similarly, in the UK Biobank, Q4 was associated with an 18% lower risk of all-cause mortality (adjusted HR: 0.82, 95% CI 0.74 to 0.91) and a 41% lower risk of cardiovascular mortality (adjusted HR: 0.59, 95% CI 0.4 to 0.87). In NHANES, Q4 was associated with lower odds of prevalent CVD (adjusted OR: 0.56, 95% CI 0.46 to 0.67), whereas in the UK Biobank, Q4 was associated with a 19% lower risk of incident CVD during follow-up (adjusted HR: 0.81, 95% CI 0.74 to 0.9). Subgroup analyses in NHANES indicated heterogeneity by ethnicity and socioeconomic status, whereas associations in the UK Biobank followed an L-shaped pattern with a flattening of estimated risk at moderate OBS levels.

Higher OBS was associated with more favourable mortality and cardiovascular outcomes. These findings indicate that OBS is a composite indicator associated with cardiovascular health at the population level.

Hand dysfunction following stroke, especially during the flaccid paralysis phase, significantly impairs patients’ motor abilities and daily functioning. Electroacupuncture (EA) is widely used in post-stroke rehabilitation; however, inconsistent clinical outcomes and lack of standardised treatment parameters have limited its broader adoption.

This protocol describes a randomised controlled trial designed to determine optimal EA parameters for post-stroke hand dysfunction using an orthogonal experimental design.

This protocol presents a single-centre, randomised controlled trial design with 10 arms. A total of 110 patients with post-stroke hand dysfunction will be randomly assigned to nine electroacupuncture groups or one sham acupuncture group in equal proportions. Participants will receive 12 treatment sessions over 2 weeks. The EA groups are designed based on a four-factor, three-level orthogonal design to systematically evaluate the main effects of acupoint selection, stimulation frequency, needle thickness and treatment duration. The primary outcome is the effective response rate, defined as reduction in the Chinese Stroke Scale (CSS) score at 2 weeks. Secondary outcomes include assessments with the Modified Lindmark Rating Scale, range of motion measures, Modified Barthel Index and hand motor subscores of the CSS. As this is a trial protocol, results are not yet available. Statistical analyses will be conducted after completion of recruitment and follow-up according to the prespecified analysis plan. Safety and adverse events will be monitored throughout the study.

This trial is designed to address the current lack of evidence-based standardisation of EA parameters for post-stroke hand dysfunction. By systematically evaluating key treatment components using an orthogonal experimental design, the study aims to identify optimal EA strategies and provide a methodological framework to improve consistency, reproducibility and clinical effectiveness in post-stroke hand rehabilitation.

This manuscript describes a study protocol and does not report any data from participants at this stage. Ethical approval for the planned trial was obtained from the Medical Ethics Committee of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine (Approval No. TYLL2024(K)072). Written informed consent will be obtained from all participants prior to enrolment. The results of the study will be disseminated through peer-reviewed journals and academic conferences.

To develop and validate a mortality-risk prediction model for patients with advanced splenomegaly-subtype schistosomiasis, enabling accurate prognosis assessment and informed resource allocation.

Retrospective, population-based cohort study using clinical data from a single-centre registry.

Endemic regions of Hubei Province, China.

The study includes 628 patients with advanced splenomegaly-subtype schistosomiasis from the Hubei Provincial Advanced Schistosomiasis Registry between September 2014 and January 2015. The splenomegaly subtype is defined as splenomegaly extending below the umbilical line or with a transverse diameter exceeding the mid-abdominal line. We divided the study population into two cohorts. The derivation cohort included 452 patients selected from several counties within the registry. These patients had a confirmed diagnosis of advanced splenomegaly-subtype schistosomiasis. Only those with complete data were retained. The external validation cohort comprised 176 patients from geographically distinct counties in the same registry, and the same inclusion and exclusion criteria were applied. 10-fold cross-validation was employed to evaluate the model’s generalisation on the derivation cohort.

6-year all-cause mortality was the outcome measure. Baseline variables, included age, serum aspartate aminotransferase, albumin, splenectomy history and frequency of ascites ≥5 episodes were analysed using Cox proportional hazards regression. Model performance was assessed via C-statistics, net reclassification improvement (NRI) and integrated discrimination improvement (IDI).

Five predictors were integrated into the mortality risk model. The C-statistic for predicting 6-year mortality was 0.79 (95% CI 0.74 to 0.83) in the derivation cohort, with robust validation in the external validation cohort (0.78, 95% CI 0.70 to 0.86). Simplified models using subsets of predictors showed slight reductions in discrimination (NRI and IDI). Patients with a frequency of ascites ≥5 episodes had significantly lower survival rates and should be given special attention in clinical practice.

The validated prediction model identifies high-risk patients using accessible clinical variables. The approach may optimise prognostication and prioritisation of healthcare resources for advanced schistosomiasis. The model’s performance remains to be confirmed in a prospectively enrolled cohort.

Tibial plateau fractures present a complex orthopaedic challenge and usually require surgical intervention to restore joint alignment and stability as well as to prevent complications. In practice, determining the most appropriate surgical approach, implant selection and positioning remains a challenge and depends on the surgeon’s experience and patient-specific factors. Therefore, this scoping review aims to map the current evidence on surgical fixation methods for proximal tibia fractures in adults. In particular, we seek to first assess study types and their distribution across levels of evidence and second to identify knowledge gaps to support evidence-based surgical planning.

The proposed scoping review will be conducted in accordance with the JBI methodology for scoping reviews and will be reported as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Information for this study will be gathered from Medline, Cochrane and Embase. Data analysis will involve categorising the studies by their level of evidence and extracting predefined parameters, including fracture characteristics, surgical approach, implant type and key findings relevant to the review question. The study focuses on surgically stabilised intra-articular proximal tibia fractures in adults. Only English- and German-language studies that are available in full text and published after 1995 will be included.

No ethical approval is required. The findings of the proposed review will be disseminated through publications in peer-reviewed journals.

To investigate the trajectories of swallowing function recovery and associated influencing factors in adult patients following orotracheal extubation in the intensive care unit (ICU).

Prospective cohort study.

Emergency ICU of a tertiary hospital in Shenyang, China.

A total of 182 adult patients who underwent orotracheal intubation were enrolled between December 2023 and December 2024 using convenience sampling. Among them, 168 patients completed all follow-up assessments, with a loss-to-follow-up rate of 10.1%.

Swallowing function was assessed using the Standardised Swallowing Assessment (SSA) at 2, 4, 6, 8, 24 and 48 hours after extubation. Latent class growth modelling (LCGM) was used to identify distinct swallowing function trajectories. Unordered multinomial logistic regression was performed to examine factors associated with different trajectory classes.

Among the 168 patients who completed all six assessments, no significant differences in baseline characteristics were observed between patients who completed follow-up and those lost to follow-up (all p>0.05). LCGM identified three distinct swallowing function trajectories: a low-risk group (46.1%), characterised by consistently low SSA scores below the dysfunction threshold (26 points); a rapid recovery group (24.6%), in which SSA scores declined to below 26 points within 24 hours after extubation and a high-risk group (29.3%), characterised by persistently elevated SSA scores above 26 points. Multinomial logistic regression analysis showed that age ≤50 years, absence of spinal cord injury or rib fractures, APACHE II score

Distinct trajectories of swallowing function recovery were observed in adult ICU patients after orotracheal extubation. Several clinical factors were associated with more favourable recovery patterns. These findings may help improve the understanding of heterogeneity in postextubation swallowing function and inform future risk stratification and individualised management strategies.

Ethics approval and consent to participate in the trial were approved by the Institutional Research Ethics Committee of General Hospital of Northern Theatre, Shenyang, Liaoning province, PR China (Project Number: Y (2023)232). Written informed consent was obtained from all participants. All procedures were conducted in accordance with relevant guidelines and regulations and the Declaration of Helsinki.

Children are largely exposed to air pollution in low- and middle-income countries, yet data on exposure and respiratory effects of air pollution remain limited. This study aimed to assess the feasibility and outcomes of joint ambulatory monitoring of exposure to fine particulate matter (particles with a diameter of less than 2.5 µm (PM_2.5)) and spirometry in children living in Abidjan, Côte d’Ivoire.

We did a cross-sectional observational study among children aged 7–17 years. After a baseline spirometry, children were asked to wear portable PM_2.5 sensors and to perform 2x3 daily flow–volume curves using a portable spirometer for 7 days. We described the proportion of acceptable measurements, per cent predicted forced expiratory volume (ppFEV₁), and hourly geometric mean PM_2.5 concentrations, and analysed the cumulative delayed effects of PM_2.5 on ppFEV₁ using distributed lag non-linear models.

Of 29 children enrolled, 18 (62.1%) were female, median age 12 years, all performed spirometry with 1101 (90.4%) of 1218 expected flow-volume curves obtained. Of these, 625 (51.3%) acceptable curves were received and 313 valid, non-duplicate curves were analysed. The median ppFEV₁ was 79.6% (71.5–87.4), with lower values in the morning than in the evening (p2.5 measurements, 93 689 (64.1%) were obtained; 6328 aberrant data were excluded. The median hourly PM_2.5 concentrations were 164.2 (107.0–272.2) µg/m³. PM_2.5 levels varied throughout the day, with pollution peaks observed in the morning. A significant decrease in ppFEV₁ was observed between 0 and 2 hours post-exposure, after an IQR increase of 120.9 µg/m³ in PM_2.5 exposure (β=–2.21; CI –3.74 to –0.69).

Ambulatory spirometry and PM_2.5 measurements are feasible with portable devices in African children. High PM_2.5 exposure and individual variability in lung function highlight the need for further research on the respiratory effects of air pollution in children.

To exploratorily examine whether parental rearing styles mediate the association between parental mental health and children’s anxiety tendencies and to explore whether these associations differ between local urban and rural-to-urban migrant children in China.

Cross-sectional survey.

Two primary schools in Hangzhou, eastern China: one primarily serving rural-to-urban migrant children and one serving local urban children.

A total of 929 children in grades 4–6 and 1273 parents participated. Inclusion criteria were parental consent and child assent; exclusion criteria were inability to complete questionnaires.

Children’s mental health was assessed using the Mental Health Test; parental anxiety and depression were measured with the Generalised Anxiety Disorder-7 and Patient Health Questionnaire-9. Parental rearing styles were assessed with the Egna Minnen Beträffande Uppfostran and the Hereford Parents’ Attitudes Survey. Mediation and structural equation modelling were applied to test associations.

In exploratory analyses, maternal anxiety was significantly associated with children’s self-blaming and sensitivity tendencies. Parental rearing styles, particularly overprotection and emotional warmth, mediated the relationship between maternal anxiety and children’s mental health outcomes. Mediation effects were stronger among urban children compared with migrant children.

Our results indicate that maternal anxiety is associated with children’s mental health, with parental rearing styles acting as mediators. Although the cross-sectional and exploratory nature limits causal inference, the findings suggest that interventions addressing both parental mental health and rearing practices may be helpful in promoting children’s mental well-being, particularly in migrant populations. Further longitudinal research is needed to clarify these pathways and to understand how contextual factors shape parent-child dynamics.

To explore long-term physical activity (PA) among patients 2 years post-transcatheter aortic valve replacement (TAVR) and assess the impact of syncope history on post-TAVR activity.

This was a cross-sectional study conducted using an on-site questionnaire.

In this cross-sectional study, we used convenience sampling to recruit participants from the outpatient department at a tertiary hospital in Shanghai, China, between July 2023 and December 2023.

Patients who had undergone TAVR for 2 years or more were included in the study.

The self-reported PA levels were assessed using the validated Chinese version of the International Physical Activity Questionnaire-Short Form. Additionally, medical records of the patients were thoroughly reviewed to accurately document the history of syncope for everyone.

Via convenience sampling, we recruited 179 consecutive participants aged 60 years and older who underwent TAVR. Only 36.31% (65/179) of patients remained physically active ≥2 years post-TAVR, with 27.37% having a syncope history. After adjusting for potential confounders, a history of syncope was independently associated with significantly lower levels of long-term PA (adjusted OR 0.287, 95% CI 0.122 to 0.675). This negative association was particularly pronounced among men and individuals with a normal body mass index (BMI).

A history of syncope is a strong independent predictor of reduced PA in the long term after TAVR. These findings highlight that patients with a history of syncope, especially men and those with normal BMI, represent a high-risk subgroup warranting particular attention in post-TAVR care. Targeted assessment and rehabilitation strategies should be considered for this population, and further research is needed to elucidate the underlying mechanisms.

Chronic non-specific low back pain (CNLBP) is a multifactorial disease involving physical dysfunction and psychological distress. Acupuncture and mindfulness-based stress reduction (MBSR) are two non-pharmacological therapies recommended by guidelines, which have been proven effective in improving the clinical symptoms of CNLBP. However, the efficacy of their combined use has yet to be explored. This study aims to explore whether the combination of acupuncture and MBSR would have different synergistic effects in patients with CNLBP compared with acupuncture or MBSR alone.

This protocol describes a randomised controlled trial with a 2x2 factorial design involving 120 CNLBP patients. Participants will be randomly allocated to four groups: (1) acupuncture, (2) MBSR, (3) acupuncture combined with MBSR, and (4) health education. The intervention period is 6 weeks. The outcome measurements will include the Visual Analogue Scale (VAS), Tactile Acuity Test, Short-form of McGill Pain Questionnairethe(SF-MPQ); Roland-Morris Functional Disability Questionnaire (RMDQ), Oswestry Disability Index(ODI), the Five Facet Mindfulness Questionnaire (FFMQ), the 21-item Depression Anxiety Stress Scales (DASS-21), the Regulatory Self-Efficacy Scale (RESE), the Beck Depression Inventory (BDI-II), the Beck Anxiety Inventory (BAI), the Fear-Avoidance Beliefs Questionnaire (FABQ) and the Pain Catastrophizing Scale (PCS);Pain Sensitivity Questionnaire(PSQ); Pittsburgh Sleep Quality Index(PSQI). All evaluations will be conducted at the baseline stage as well as 6 weeks and 4 months after the implementation of the intervention measures.

Ethics approval was obtained from the Ethics Committee of the Affiliated Rehabilitation Hospital of the Fujian University of Traditional Chinese Medicine (2024KY-041-04). The results of the study will be disseminated through peer-reviewed publications and at scientific conferences.

The number of people living with obesity is increasing rapidly worldwide, and the WHO estimates approximately 5 million deaths yearly from non-communicable diseases related to elevated body mass index (BMI). The most effective treatment for weight loss is bariatric surgery, but due to the associated risks and the need for lifelong care, this is not a viable treatment for every patient. With the advent of gut-hormone-based medications to treat obesity, the effectiveness of non-surgical treatment is approaching that of surgical interventions. We therefore aim to investigate the beneficial and harmful effects of laparoscopic bariatric surgery versus any non-surgical treatment.

We will conduct a systematic review with meta-analysis applying our eight-step procedure to assess thresholds for clinical significance and trial sequential analysis to mitigate the risk of random errors. To identify relevant trials, we will search for both published and unpublished trials, without any language restriction, in major medical databases (CENTRAL, MEDLINE, EMBASE, LILACS, SCI-EXPANDED and CPCI-S) and trial registries. The date range covered by the search is from database inception until final search date—within 3 months prior to submission of final results manuscript. Two review authors will independently screen references, extract data and perform risk-of-bias assessment using the Cochrane Risk of Bias Tool 2 and the Grading of Recommendations, Assessment, Development and Evaluations. We will include randomised clinical trials comparing laparoscopic surgery currently in use with any non-surgical comparator in adults or adolescents with BMI >30 kg/m². Quasi-randomised studies or non-randomised studies will not be included. Our critical outcomes are all-cause mortality, serious adverse events and quality of life, and our important outcomes are major cardiovascular events, weight at follow-up, physical function and glycaemic control. In addition, we have two explorative outcomes: metabolic syndrome or Z-score and reported incident of alcohol abuse or other addictive disorder or self-inflicted harm.

This review will collect and perform secondary analysis of data from publicly available sources and ethical approval is therefore not required. The findings will be published in peer-reviewed journals and presented at relevant scientific conferences. We will strive to publish with open access. Awareness will be made through social media platforms. This review aims to help clinicians in identifying best practices in the wide-spanning field of obesity treatment.

Patient self-testing (PST) for warfarin management is well-established in developed countries but remains underused in developing regions. This study compared the safety and effectiveness of PST with usual care (UC) in China.

A multicentre, open-label, randomised, controlled trial.

A total of five centres participated in this study, including one provincial tertiary hospital, two municipal tertiary hospitals and two primary hospitals.

Patients undergoing mechanical heart valve (MHV) replacement at five centres were prospectively enrolled. Patients were trained and stratified according to time on warfarin at enrolment and were randomly assigned to the PST or UC group.

The PST group used a point-of-care testing device for at-home international normalised ratio (INR) monitoring with pharmacist-guided warfarin dosing, while the UC group attended outpatient clinics for INR monitoring and dosing.

The primary outcome was the difference in time in therapeutic range (TTR). The secondary outcomes were incidences of major bleeding, thromboembolism and all-cause deaths in 12 months.

From March 2021 to March 2023, a total of 556 patients were enrolled, with a mean age of 47.5 years, 45.1% being male. 342 were newly initiating warfarin therapy, while 214 had been on warfarin for over 6 months. Baseline characteristics were similar between the PST and UC groups. The PST group showed significantly higher TTR (67.2% vs 55.1%, p

A pharmacist-led PST intervention with ongoing education and counselling led to improved TTR and clinical outcomes in patients with MHV in China.
