THSD7B (thrombospondin type-1 domain-containing 7B) has been implicated in several malignancies; however, its role in gastric adenocarcinoma remains unclear. This study aimed to investigate the expression pattern, clinical significance, and biological function of THSD7B in gastric adenocarcinoma. Public datasets from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) were analyzed to evaluate THSD7B expression and its association with clinical outcomes. Functional enrichment analysis was performed to explore potential biological processes. In vitro assays, including cell proliferation, colony formation, wound healing, and Transwell invasion, were conducted following THSD7B knockdown or overexpression in gastric cancer cell lines. In addition, a xenograft model was established to assess tumor growth in vivo. THSD7B expression was significantly elevated in gastric adenocarcinoma tissues compared with normal controls and was associated with patient survival. Functional analyses suggested that THSD7B-related genes were mainly enriched in cell adhesion and cytoskeleton-associated processes. In vitro experiments showed that THSD7B knockdown suppressed cell proliferation, migration, and invasion, whereas overexpression produced the opposite effects. Consistent with these findings, THSD7B modulation was accompanied by alterations in adhesion-related signaling molecules and phenotype-associated protein expression. In vivo, THSD7B promoted tumor growth in xenograft models. In conclusion, THSD7B is associated with tumor progression and clinical outcomes in gastric adenocarcinoma and may be involved in the regulation of cell motility-related processes. These findings suggest that THSD7B may serve as a potential biomarker in gastric cancer.To provide evidence for selecting and developing reliable clinical assessment tools for hypoglycemia in diabetic kidney disease patients during haemodialysis.
Review.
Systematic searches were performed in 9 Chinese and English databases to collect literature regarding the development of hypoglycemia risk prediction models in haemodialysis patients with diabetic kidney disease. Two reviewers independently performed literature screening, data extraction, risk-of-bias assessment, and applicability evaluation. The Prediction Model Risk of Bias Assessment Tool was used to assess the risk of bias and applicability of the included studies. Meta-analysis was conducted using R software.
CNKI, Wanfang, VIP, CBM, PubMed, Cochrane Library, EMbase, Web of Science, and CINAHL. The search period covered from the establishment date of each database to December 2025.
Six studies, comprising six prediction models, were included. Two studies performed internal validation, and three conducted external validation. All models reported the area under the curve, ranging from 0.813 to 0.866, and calibration measures. Four studies were rated as having a high risk of bias, while all six demonstrated good overall applicability. The meta-analysis showed that the pooled AUC value of the six studies was 0.846 (95% CI: 0.823–0.867).
Research on hypoglycemia risk prediction models in haemodialysis patients with diabetic kidney disease remains in the developmental stage. Although the included prediction models exhibited satisfactory apparent discriminatory ability and clinical applicability, most of the original studies suffered from a high risk of bias and lacked adequate validation. The true predictive performance and clinical application value of these models remain to be further verified. Accordingly, routine and unconditional clinical application is not recommended at this stage. Future studies should include more high-quality, multicenter external validation and develop models with high generalizability, favourable clinical applicability, and robust predictive performance to facilitate early identification of hypoglycemia risk in this population.
This study systematically evaluated the hypoglycemia risk prediction models for diabetic kidney disease patients during haemodialysis, and the research on hypoglycemia risk prediction models for maintenance haemodialysis patients during dialysis is still in the development stage. This study provides a reference for clinical medical staff to select or develop hypoglycemia risk prediction and assessment tools for diabetic kidney disease patients during haemodialysis.
This study was conducted in accordance with the relevant guidelines of the EQUATOR Network and followed the TRIPOD-SRMA Checklist.

Study aimsUsing a cross-country lens, we investigate the links between longitudinal work trajectories and health among parents with children under age 18.
BackgroundEmployment serves as a valuable resource, affording us a decent standard of living. The rising dominance of digital and technology, together with the service economy since the 1980s, has transformed the utility of employment from a resource to a vulnerability, subjecting more families to uncertain, unstable, and insecure work. Nonstandard work schedules or shiftwork, which often fall outside regular 9-to-5 daytime hours and can be unpredictable, carry potential health consequences.
MethodsUsing the longitudinal data from Australia (HILDA), Germany (SOEP), the UK (UKHLS), and the US (NLSY79), we used sequence analysis to first chart parental work schedule patterns between three stages of the life course, 25–34, 35–44, and 45–54, to show the changes and transitions in work patterns. We then conducted multivariate regression analysis to examine how variations in parental work patterns may shape individual health (i.e., physical and mental health) at ages 35/40, 45/50, and 55/60 while controlling for a rich set of sociodemographic characteristics.
ResultsOur sequence analyses uncovered roughly 4–6 work patterns during those three periods, revealing the heterogeneities of parental work trajectories that might correspond to childrearing demands and their sociodemographic backgrounds. We also found that mainly not-working pattern or volatile work arrangements (e.g., switching between daytime and non-daytime hours) were associated with significantly poorer physical and mental health; however, the persistence and magnitude of these associations varied by country.
ConclusionsThis study advances our understanding of the critical role of employment in our health from a cross-country perspective and bears important implications for the intergenerational transmission of employment and health vulnerabilities.

Airway foreign-body aspiration in adults is uncommon but can be life-threatening.Flexible bronchoscopy is the standard first-line therapy,but critically ill patients may need extracorporeal life support.This study aims to characterize the diagnosis,management,and outcomes of adult airway foreign-body cases treated at a single center over nearly 12 years to inform a standardized clinical pathway.A single-center retrospective observational study of consecutive patients aged ≥14 years with confirmed airway foreign body who were treated at a tertiary hospital in China were conducted.Medical records of consecutive adolescent and adult patients diagnosed with airway foreign-body aspiration and admitted to the hospital from 01/01/ 2014–30/11/2025 were reviewed.Data included demographics,imaging,extraction method, respiratory support and so on.Descriptive statistics were reported as medians with interquartile ranges or counts and percentages.A total of 41 patients were included,with a median age of 59.5 years(interquartile ranges 51–72) and 65.85% male.Flexible bronchoscopy was attempted as the primary intervention in 38 patients(92.68%) and succeeded in 81.58%(31/38) to remove airway foreign body.Most patients(78.05%) required only nasal cannula oxygen,while nine patients(21.95%) needed advanced support including mechanical ventilation (14.63%),high-flow oxygen(4.88%),and extracorporeal life support (2.44%).At discharge,most survivors had a good neurological outcome,with 36 patients(87.80%) having a Cerebral Performance Categories score of 1.The 28-day survival rate was 92.68%.These findings show that flexible bronchoscopy is an effective first-line therapy,and rigid bronchoscopy or surgery is useful when flexible bronchoscopy fails.In unstable cases,timely extracorporeal life support can bridge to definitive removal.These results support a tiered,multidisciplinary approach incorporating early chest computed tomography,flexible bronchoscopy,and escalation to advanced airway or extracorporeal support.To summarise the evidence on long-term and infrequent harms following selected spinal and paraspinal injections and denervation procedures for chronic non-cancer spine pain.
Systematic review and meta-analysis.
MEDLINE, EMBASE and Cumulative Index to Nursing and Allied Health Literature from inception to October 2023.
Non-randomised studies reporting on harms of selected interventional procedures administered to adults living with chronic axial or radicular non-cancer spine pain with ≥4 weeks of follow-up.
A parallel guideline panel provided input on the scope, design and interpretation of this systematic review, including selection of adverse events for consideration. Systematic literature screening, data abstraction and risk of bias appraisal were conducted independently and in duplicate by pairs of reviewers. We used random-effects models for all meta-analyses and the Grading of Recommendations Assessment, Development and Evaluation approach to evaluate the certainty of evidence.
We included 60 longitudinal studies (56 non-comparative, 4 comparative) that enrolled 4966 patients with chronic non-cancer spine-related pain. 31 studies investigated radiofrequency ablation or denervation, 22 epidural injections and 11 joint injections or nerve blocks. Low certainty evidence suggests that joint targeted steroid injection and epidural steroid injection for chronic spine pain may result in temporary altered level of consciousness (incidence: 2.1%; 95% CI 1.1% to 4.0%), joint radiofrequency nerve ablation, joint targeted steroid injection and epidural injection of local anaesthetic and steroids may result in deep infection (incidence: 0.7%; 95% CI 0.3% to 2.0%), epidural steroid injection, joint radiofrequency nerve ablation and joint targeted injection of local anaesthetic and steroids may result in dural puncture (incidence: 1.4%; 95% CI 0.5% to 4.3%), and dorsal root ganglion radiofrequency and joint radiofrequency nerve ablation with or without joint-targeted injection of steroids may result in prolonged pain or stiffness (incidence: 8.6%; 95% CI 6.3% to 11.6%). Several interventional procedures may result in metabolic complications and prolonged sensory deficits, but the supporting evidence was only very low certainty. Most complications resolved spontaneously or with conservative management.
Low certainty evidence suggests that several common interventional procedures for chronic spine pain show risk of deep infection, dural puncture, temporary altered level of consciousness and prolonged pain or stiffness. Other harms are uncertain due to very low certainty evidence, and catastrophic outcomes were not reported in the small studies that contributed to our analyses.
To identify early cardiovascular changes in normotensive obstetricians, a high-stress group, using non-invasive haemodynamic monitoring, and to examine the association between burnout and haemodynamic parameters.
Cross-sectional study.
A single tertiary hospital in China.
A total of 120 healthy Han Chinese adults (aged 25–45 years, both sexes) were enrolled using stratified random sampling by age and categorised into three groups: obstetricians, clinical support staff and administrative personnel. Of these, 105 (87.5%) completed the study and entered the final analysis (obstetricians n=40; clinical support staff n=33; administrative personnel n=32); 15 were excluded due to incomplete questionnaire data. Key exclusion criteria were chronic medical conditions, medication use, acute illness, a clinical shift within 24 hours before measurement, pregnancy or lactation, body mass index extremes (≤18.5 or ≥ 28 kg/m2) and major life events within the past 6 months. Burnout was assessed using the Maslach Burnout Inventory-Human Services Survey; workload, lifestyle and family history were collected via questionnaire.
Advanced haemodynamics were assessed via Ultrasonic Cardiac Output Monitor. The primary outcome was cardiac power output (CPO). Secondary outcomes included other non-invasive haemodynamic parameters, such as cardiac index (CI), systemic vascular resistance index, Smith–Madigan inotropy index and corrected flow time.
Severe burnout was associated with reduced CPO and CI (–0.152 W and –0.403 L/min/m2, respectively; both p2, respectively; both p
In high-stress populations, advanced haemodynamic patterns may serve as an early-warning biomarker for burnout, guiding personalised exercise advice. Longitudinal studies are needed to confirm their predictive value.

This randomized controlled trial is aimed at evaluating whether external fixation of the urinary catheter to the body surface represents a low-value nursing intervention for patients undergoing transurethral resection of the prostate (TURP). A total of 208 patients who received indwelling urinary catheters after TURP in a tertiary hospital in Qingdao, China between June 2024 and May 2025 were randomly assigned to one of two groups: a nonexternal fixation group (n = 103) and an external body surface fixation group (n = 105). A between-group comparison of outcomes included postoperative hematuria, incidence of catheter-associated urinary tract infection (CAUTI), unplanned catheter removal, occurrence of urinary catheter-related meatal pressure injury (UCR-MPI), and associated economic costs. No significant differences were observed between the two groups in terms of postoperative hematuria or CAUTI incidence (P > 0.05). Unplanned catheter removal did not occur in either group. However, UCR-MPI occurred significantly more frequently in the external fixation group (9 patients) than it did in the nonexternal fixation group (1 patient) (Pby Xuejin Ye, Sheng Chen, Lin Guo, Xiaohan Ma, Lingling Wu, Yiwen Li, Ting Zhang, Peng Jiang, Hongjun Gao
BackgroundAcute kidney injury (AKI) complicates the course of critical illness and carries high short- and long-term mortality rates; however, reliable early prognostic markers remain limited. The leuko-glycemic index (LGI), the product of white blood cell counts and blood glucose, has shown prognostic value in other acute conditions; however, its role in intensive care unit (ICU) patients with AKI remains unexplored.
MethodsIn this multicenter retrospective cohort study, we analyzed 112,235 adult ICU admissions from the MIMIC-IV (n = 54,840) and eICU-CRD (n = 57,395) databases. Patients with multiple ICU stays and those aged Results
Higher LGI quartiles were associated with progressively worse survival (p Conclusion
LGI may be an independent biomarker associated with short-term mortality in ICU patients with AKI. Its potential clinical relevance warrants further investigation and validation in larger cohorts.

BackgroundDiabetic peripheral neuropathy (DPN) is a common complication of type 2 diabetes mellitus (T2DM) and is closely linked to immune and inflammatory dysregulation. Multi-component pharmacological interventions have been explored as complementary approaches for metabolic and immune modulation; however, their effects on DPN and related mechanisms remain incompletely understood.
MethodsA rat model of T2DM-associated peripheral neuropathy was established, and a multi-component pharmacological intervention (MPCI) was administered for 8 weeks. Peripheral nerve dysfunction was evaluated by motor and sensory nerve conduction velocities (MNCV and SNCV), behavioral outcomes, and histological/ultrastructural assessments. In parallel, spleen tissues were collected for transcriptomic profiling. RNA sequencing was performed to identify differentially expressed genes and immune-related pathways, and representative molecules involved in inflammatory regulation were further validated using western blotting and quantitative real-time PCR in sciatic nerve tissue.
ResultsMPCI administration significantly ameliorated peripheral nerve dysfunction in T2DM rats, as evidenced by improved nerve conduction velocities and pathological features. Transcriptomic analysis of spleen tissue revealed that MPCI was associated with broad remodeling of diabetes-related immune and inflammatory gene programs. In parallel, sciatic nerve analyses showed attenuation of NF-κB/c-Jun–associated inflammatory signaling and modulation of inhibitory regulators at both the protein and mRNA levels.
ConclusionThese findings indicate that MPCI improves T2DM-associated DPN and is associated with splenic immune remodeling and attenuation of peripheral nerve inflammatory signaling, providing exploratory evidence for associations between splenic immune transcriptomic remodeling and peripheral nerve inflammatory signaling.
To assess caregiver burden and its relationship with health literacy, self-efficacy, stigma, and social support among caregivers of children with tuberculosis in Shanghai, China.
Explanatory sequential mixed-methods design.
In the quantitative phase, 132 caregivers were recruited from a Shanghai Hospital, and 21 participated in the qualitative interviews. Data were collected (April 2023–April 2025) using the Zarit Burden Interview scale, Chinese Health Literacy Scale for Tuberculosis, General Self-Efficacy Scale, Tuberculosis-related Stigma Scale, Multidimensional Scale of Perceived Social Support, and semi-structured interviews. Quantitative data were analysed using descriptive statistics and multiple regression analyses, and qualitative data were analysed using content analysis.
Most caregivers were mothers (72.7%). Burden levels were classified as mild (58.3%), moderate (27.3%), or severe (2.3%). The quantitative analysis identified lower health literacy, limited social support, reduced self-efficacy, and being a female caregiver as significant predictors. Social support partially mediated and self-efficacy mediated the effect of perceived stigma and health literacy on caregiver burden, respectively. Qualitative themes revealed psychological and physical effects, impact on social life, and coping strategies.
Caregiver burden in paediatric tuberculosis is multidimensional and influenced by complex mechanisms. Interventions should address health literacy gaps, enhance self-efficacy, strengthen social support systems, and implement targeted stigma-reduction strategies while considering developmental-stage-specific needs.
Healthcare systems should routinely assess caregiver burden, and multidisciplinary teams should be trained to provide integrated targeted support.
This study demonstrates distinct stigma pathways and comprehensively shows that caregiver burden is significantly associated with modifiable psychosocial factors. Consequently, healthcare providers should develop targeted support interventions that address both psychological and practical caregiving challenges, ultimately contributing to improved patient care outcomes and caregiver well-being in tuberculosis management.
This study adheres to the Good Reporting of A Mixed Methods Study checklist.

To estimate the prevalence of loneliness, social isolation, and their co-occurrence among people living with HIV and to explore factors explaining heterogeneity between estimates.
A systematic review and meta-analysis.
PubMed, Cochrane Library, SciELO Citation Index (via Web of Science), Scopus, Embase, PsycArticles, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched from inception until November 1, 2024 for relevant studies.
Study eligibility, data extraction, and methodological quality assessment were conducted independently by two reviewers. Random-effects meta-analysis was used to estimate pooled prevalence. Subgroup analyses were performed.
A total of 66 studies were included. The pooled prevalence of loneliness was 46.9% and that of social isolation was 25.9%. However, heterogeneity was very high across studies, and these pooled estimates should therefore be interpreted cautiously. Subgroup analyses suggested regional variation in both loneliness and social isolation. Other subgroup findings should be interpreted cautiously because some subgroup estimates were based on small numbers of studies.
Loneliness and social isolation are highly prevalent among people living with HIV. Population-specific intervention strategies are needed to reduce this burden, and future studies should further examine contextual and demographic differences to guide intervention design.
Routine HIV services should include screening and referral pathways for loneliness and social isolation.
This systematic review identified the pooled prevalence of loneliness and social isolation among people living with HIV, highlighting a substantial and clinically relevant burden. The findings may influence HIV nurses' practice and inform care approaches for other clinical populations experiencing loneliness and social isolation.
This systematic review followed the PRISMA and MOOSE reporting guidelines.

To systematically review qualitative studies on the self-management experiences and needs of patients with chronic obstructive pulmonary disease (COPD) and to provide evidence for developing needs-based self-management intervention strategies.
A systematic review and meta-aggregation of qualitative studies conducted in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research statement.
PubMed, Cochrane Library, Web of Science, Scopus, CINAHL, Embase, CNKI, Wanfang Database, VIP Database and CBM were searched from database inception to March 2025 for qualitative studies on COPD self-management experiences and needs.
Qualitative studies involving adults (≥18 years) with a confirmed diagnosis of COPD that reported patients’ real feelings, experiences and needs during the self-management process in any setting (hospital, community or home). Studies were excluded if the full text could not be obtained or data were incomplete, if they were duplicate publications or if they were not published in Chinese or English.
Two reviewers independently screened titles, abstracts and full texts, extracted data using a standardised form and assessed methodological quality using the 2016 Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research. Findings (participants’ quotations and authors’ interpretive statements) were synthesised using a JBI meta-aggregation approach to develop categories and overarching synthesised findings.
15 qualitative studies were included, comprising 251 patients with COPD. A total of 52 findings were identified, grouped into 13 categories and synthesised into 4 overarching findings: (1) physical symptom burden strongly shapes psychological well-being during COPD self-management; (2) patients face multiple and interrelated barriers to effective self-management; (3) some patients develop active coping strategies and self-management resources; and (4) patients express multidimensional and continuing support needs.
Patients with COPD experience substantial physical and psychological distress and face multiple challenges in the self-management process. Healthcare professionals should prioritise patients’ lived experiences, establish comprehensive and coordinated support systems and develop diversified, needs-based intervention strategies to address patients’ multidimensional needs, thereby enhancing self-management capacity and improving quality of life.

Hearing loss (HL) imposes a substantial burden on families and society and is the largest modifiable risk factor for dementia. As a practical and non-invasive approach to managing HL, hearing aid use has been associated with a reduced risk of incident dementia and global cognitive decline. However, high-level evidence on the cognitive benefits of hearing aids among those at high dementia risk is scarce and adherence to hearing aid use remains challenging. Our study aims to explore whether a family-supported hearing aid use behaviour intervention, guided by the integrated framework of self-determination theory, technology acceptance model and family social support theory, can improve cognitive function in Chinese older adults with both HL and mild cognitive impairment (MCI).
This study is a two-arm, single-blinded, randomised controlled trial. A total of 150 participants with HL and MCI will be randomly assigned in a 1:1 ratio to either an intervention group (hearing aid use and family intervention) or a control group (hearing aid use and regular health education). All interventions will last for 4 months. Hearing aid use will be delivered by professional audiologists, while family caregivers will deliver the behavioural intervention at home after receiving standardised training from researchers and guidance through structured manuals. Furthermore, family caregivers will be guided through a WeChat group to address unresolved issues related to hearing aid maintenance and intervention skills. The primary outcome is cognitive function measured by the Montreal Cognitive Assessment–Hearing Impairment at baseline and follow-up. Secondary outcomes include adherence score to hearing aid use measured by daily duration and weekly frequency, hearing aid use skills, motivation, activities of daily life, quality of life, depressive symptoms, subjective cognitive decline, social support, self-efficacy, healthcare utilisation, autonomy support and caregiver burden.
The study was approved by the Institutional Review Board of Peking University. Research findings will be published in peer-reviewed journals and at national and international conferences.

Accessing samples from mediastinal and hilar lymph nodes is considerably more difficult, rendering the diagnosis of tuberculous mediastinal and hilar lymphadenopathy particularly challenging. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive interventional technique used for sampling mediastinal and hilar lymph nodes. Nanopore sequencing technology (NST) permits the rapid identification of Mycobacterium tuberculosis genes directly from clinical samples. NST has significantly improved the diagnostic accuracy for both pulmonary and extrapulmonary tuberculosis; its accuracy in diagnosing tuberculous mediastinal and hilar lymphadenopathy using EBUS-TBNA specimens has not yet been systematically evaluated.
Adhering to Preferred Reporting Items for a Systematic Review and Meta-Analysis Protocols (PRISMA-P) and PRISMA-Diagnostic Test Accuracy Studies (DTA) guidelines, this protocol (PROSPERO: CRD420251274529) will synthesise evidence from five international databases (PubMed, Embase, SCOPUS, Web of Science and Cochrane Library) and two Chinese databases (China National Knowledge Infrastructure and Wanfang Database). The literature search is planned to be conducted between 1 December 2026 and 31 December 2026 (start and end dates of the search). The publication dates of the included literature ranged from the inception of the relevant databases to 31 December 2026. Data extraction from the included studies is anticipated to be completed by 31 May 2027, and the final reporting of findings is expected by 31 December 2027. Study selection followed the PICT framework: participants (P): patients with suspected tuberculous mediastinal and hilar lymphadenopathy; index test (I): the index test was defined as NST; comparator (C): the reference standard for tuberculous lymphadenopathy; target condition (T): the target condition was confirmed tuberculous mediastinal and hilar lymphadenopathy. Two independent investigators will perform a three-step screening process, extract data and assess methodological quality using Quality Assessment of Diagnostic Accuracy Studies. Bivariate random-effects models implemented in STATA V.15.0 will be used to pool sensitivity, specificity and hierarchical summary receiver operating characteristic curves when four or more studies are available; for fewer studies, Meta-DiSc V.1.4 will be employed. If substantial heterogeneity is detected (I² statistic >50%), meta-regression and subgroup analysis will be performed across prespecified covariates.
This study is based on publicly available data and therefore does not require ethics committee approval. Upon completion, the findings will be submitted for publication in a peer-reviewed medical journal. The review is conducted in accordance with established guidelines for systematic review and meta-analysis.

Chronic non-healing wounds represent a major global public health challenge. Their persistence is frequently attributed to localized biological deficits that cause them unresponsive to conventional therapeutic modalities. While Platelet-Rich Plasma (PRP) has demonstrated promising results as an adjunctive treatment by delivering highly concentrated growth factors, its clinical application is currently impeded by a lack of clinical standardization, particularly optimal injection frequency, interval, and dosage. The aim of this study is to rigorously evaluate the efficacy and safety of a specific, non-intensive two-dose PRP injection protocol for accelerating the reduction of wound area in patients with various types of refractory chronic wounds. We conducted a prospective, single-arm, pretest-posttest study enrolling 18 patients with refractory non-healing wounds, defined as lesions persisting for a minimum period of 4 weeks which had failed to achieve definitive closure under optimized standard care. Autologous high-concentration PRP was injected intradermally around the wound margin at baseline (Day 0) and again 3 weeks later (Day 21). Wound area was digitally measured at baseline and subsequently at 7, 11 and 15 weeks. The primary outcome was the mean reduction in wound area (cm2) at the 15-week follow-up, assessed using a Paired Samples t-test. The mean patient age was 57.89 ± 15.64 years, and wounds had a mean chronicity of 15.83 ± 19.05 months. The PRP preparation achieved a mean platelet concentration 8.5 times greater than the peripheral blood threshold (first injection) and 7.0 times greater than the threshold (second injection), confirming high therapeutic quality. Analysis of the total cohort demonstrated a statistically significant reduction in mean wound area from baseline 27.41 ± 70.38 cm2 to 15 weeks 21.5 ± 68.96 cm2. Three patients (16.67%) achieved complete epithelialization. Subgroup trends suggested diabetic and venous ulcers responded more favourably than radiation-induced ulcers. The protocol was safe, with no systemic or severe localized adverse events observed among participants. The defined two-dose PRP injection protocol provides a clinically effective and safe adjunctive therapy that significantly promotes wound area reduction in challenging chronic non-healing wounds. This reproducible, low-frequency protocol offers a rationale for standardization in advanced wound care, warranting validation through future large-scale Randomized Controlled Trials (RCTs).
To investigate how patients with sarcoma present prior to diagnosis—through a general practitioner (GP) or another healthcare professional (HCP)—and describe presenting symptoms.
International observational cohort study.
Data were obtained from the longitudinal ‘QUality of life and Experiences of Sarcoma Trajectories’ (QUEST) cohort study, conducted across the Netherlands, the United Kingdom (UK), Australia and New Zealand.
Among 572 patients, 487 (85.1%) started their diagnostic trajectory at the GP (subcohort 1) and 85 (14.9%) with another HCP (subcohort 2)—mainly medical specialists treating unrelated conditions (36/85; 42.4%). Soft tissue sarcoma patients most often reported swelling, whereas bone sarcoma patients reported unexplained pain. Notably, 31/85 (36.5%) of subcohort 2 were asymptomatic. Reasons for delaying GP visits included assuming symptoms were minor and expecting them to resolve. Patients sought care when, among others, symptoms persisted and worsened.
Most patients first consulted a GP, underlining the role of primary care in sarcoma diagnosis internationally. Due to rarity and nonspecific symptoms, faster diagnosis remains challenging, requiring improvements in both primary and specialist care.

BackgroundLow-intensity focused ultrasound (LIFU) is a non-invasive neuromodulation technique with high spatial precision and the ability to reach deeper brain regions, offering potential advantages for post-stroke rehabilitation. Repetitive transcranial magnetic stimulation (rTMS) is a widely adopted non-invasive brain stimulation technique that modulates cortical excitability to promote neuroplasticity. However, direct head-to-head comparisons between these two modalities for post-stroke motor recovery remain limited.
ObjectiveTo perform a secondary head-to-head comparison of LIFU and repetitive transcranial magnetic stimulation (rTMS) for motor recovery after stroke, based on a prospectively registered randomized controlled trial.
MethodsThis secondary analysis included patients with subacute stroke who received two weeks of standard rehabilitation combined with either LIFU (n = 25) or rTMS (n = 25) targeting the ipsilesional primary motor cortex. LIFU parameters: 0.5 MHz, spatial-peak pulse-average intensity (ISPPA) 10.2 W/cm² (free-field), pulse duration 0.2 ms, duty cycle 20%, 20 minutes per session, five days per week for two weeks (10 sessions total). rTMS parameters: 10 Hz, 80% resting motor threshold, 1,000 pulses per session (20 trains of 5 seconds), 20 minutes per session, five days per week for two weeks (10 sessions total). Motor outcomes were assessed using the Fugl–Meyer Assessment (FMA; upper and lower extremities), Modified Barthel Index (MBI), and Brunnstrom stages. Resting-state functional near-infrared spectroscopy (fNIRS) was used to evaluate cortical activity and functional connectivity before and after the intervention. Primary analyses were conducted in the intention-to-treat (ITT) population (n = 50), with completer analyses (n = 43) performed as sensitivity analyses.
ResultsBoth groups showed significant within-group improvements in FMA and MBI after the intervention (all p 0.05), and completer analyses yielded consistent between-group conclusions. In contrast, change-from-baseline analyses demonstrated greater improvements in FMA scores in the LIFU group compared with the rTMS group (ΔFMA upper limb: median 7 [IQR 3–10.5] vs. 2 [1–3], p = 0.001; lower limb: 3 [1–4.5] vs. 1 [0–1.5], p Conclusion
LIFU and rTMS were associated with comparable short-term motor outcomes in subacute stroke. Differences observed in change-from-baseline motor improvements and exploratory neuroimaging measures suggest potential divergence in recovery dynamics and cortical modulation, warranting further investigation in larger, longitudinal studies.
Trial registrationThis study was derived from a prospectively registered, three-arm randomized controlled trial in the Chinese Clinical Trial Registry (ChiCTR2500114687). The present manuscript reports a secondary head-to-head comparison between the two neuromodulation intervention arms.
