BackgroundThe overlap between non-erosive reflux disease (NERD) and epigastric pain syndrome (EPS, a subtype of functional dyspepsia) is common, yet its associated factors remain poorly defined. We aimed to identify factors associated with symptom severity in NERD-EPS overlap, focusing on psychosocial and somatic factors.
MethodsIn this multicenter cross-sectional study, 800 patients meeting Rome IV criteria for NERD-EPS overlap were enrolled. Standardized questionnaires assessed gastrointestinal symptoms (GSRS), somatic symptoms (PHQ-15), anxiety/depression (PHQ-4), and sleep quality (SRSS). Multivariable regression models identified factors independently associated with GSRS scores, adjusted for demographics and clinical covariates. Interaction terms were tested to assess whether the association between one factor and GSRS scores varied across different levels of another factor.
ResultsOf the 800 patients, 67% were female, and the mean age was (44.50 ± 14.43) years. 67% had mild or more sleep problems, and 47% had anxiety or depression. Somatic symptoms (PHQ-15) showed the strongest association with GSRS scores (β = 0.617, P P P = 0.026). Urban residence (β = 0.071) and mixed labor type (β = −0.066) were also independently associated with symptom burden.
ConclusionSomatic symptoms, psychological distress, and sleep disturbances were the factors most strongly associated with symptom severity in NERD-EPS overlap, with additional contributions from younger age, male sex, and urban residence. Our findings advocate for integrated biopsychosocial interventions to alleviate symptom burden in this population.

BackgroundQingdao, a historically high-risk area for hemorrhagic fever with renal syndrome (HFRS) in China, is undergoing agricultural mechanization and urbanization. However, the specific risk factors for HFRS in this context remain unclear. This study sought to determine the risk factors for HFRS in Qingdao.
MethodsCommunity-based, 1:2 case-control study. Each case was matched with two healthy neighborhood controls based on biological sex, age, and the same neighborhood or village. Univariate and multivariate conditional logistic regression analyses were performed. Furthermore, stratified analyses were performed to explore risk factor heterogeneity between the peak season for Hantaan virus (HTNV) type HFRS (October-January) and other months.
Results93 cases (73.2%, 93/127) reported from January 2022 to September 2023 and 186 controls completed this questionnaire. Farmers accounted for the highest proportion (68.8%, 64/93). In multivariate logistic regression analysis, there were three significant risk factors for HFRS: piles of firewood and/or grain in residential yards (odds ratio [OR]=3.75, 95% CI: 2.14–6.55), mite and/or flea bites (OR=1.83, 95% CI: 1.06–3.18) and contacting with rats and/or their excreta (OR=1.73, 95% CI: 1.09–2.74); three variables represented significant protective factors for HFRS: frequency of sun exposure for quilts and bedding (OR=0.41, 95% CI: 0.19–0.90), rodent control measures at home (OR=0.50, 95% CI: 0.30–0.81) and knowing the main sources of HFRS transmission (OR=0.58, 95% CI: 0.36–0.90). Stratified analysis revealed that the influence of these factors varied by season, with rodent contact and control measures being particularly salient during the HTNV peak season.
ConclusionThis study provides the first comprehensive evidence of risk and protective factors for HFRS in Qingdao, highlighting the role of rodent control, promoting comprehensive health education, environmental management, and personal protection. However, the results should be interpreted considering the study’s limitations, including a 73.2% response rate and the potential for recall bias.
Patients undergoing anterior cruciate ligament reconstruction (ACLR) and patellar fracture frequently present with substantial pain, swelling and inflammation. These pathophysiological changes not only intensify postoperative pain but also compromise the intra-articular environment via mechanical compression and localised microcirculatory deficits, thereby impeding recovery. Conventional interventions for postoperative swelling, such as cryotherapy and physical agent modalities, are commonly applied yet exhibit limited efficacy. Multilayer low-stretch bandage (MLB), with its gradient compression properties, has recently demonstrated superior swelling control and functional restoration; however, existing research primarily assesses short-term outcomes and lacks a systematic analysis across the postoperative continuum—acute, subacute and chronic phases—as well as long-term follow-up. This study therefore employs a multi-temporal intervention design and extended follow-up to evaluate the effectiveness of MLB in managing swelling, modulating pain and enhancing long-term knee function and activities of daily living across different recovery stages. The findings aim to furnish high-level evidence for knee rehabilitation protocols, refine clinical practice and ultimately improve patient quality of life.
This prospective, single-blind, randomised controlled trial will enrol 36 patients following ACLR and patellar fracture. Participants will be allocated at a 1:1 ratio through computerised randomisation to either an experimental group receiving MLB plus conventional rehabilitation, or a control group receiving conventional rehabilitation alone. The study spans 12 weeks, with follow-up assessments scheduled at baseline (T0), 4 weeks (T1), 8 weeks (T2) and 12 weeks (T3). Outcome measures comprise the Hospital for Special Surgery (HSS) Knee Rating Score, affected limb oedema regression rate, Visual Analogue Scale (VAS) pain score, knee range of motion, quadriceps and hamstring muscle strength, centre of pressure (COP) displacement parameters, proprioceptive testing, the 36-Item Short Form Health Survey (SF-36) and the Holden Walking Function Classification. A subsequent 1-year follow-up will assess long-term efficacy and patient satisfaction, while adverse events are strictly monitored throughout the entire study period. Adherence to Consolidated Standards of Reporting Trials guidelines is maintained, and a single-blind design ensures that both participants and assessors remain unaware of group assignments. This trial aims to establish an evidence-based foundation for optimising postoperative rehabilitation in this patient population.
Ethical approval for the study was obtained from the Medical Ethics Committee of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School (2025-0141-01). The results of the study will be published in a peer-reviewed medical journal.

IntroductionIrinotecan is a chemotherapy agent commonly prescribed for metastatic colorectal cancer but often leads to neutropenia. Variations in genes encoding drug-metabolizing enzymes and transporters may affect the toxicity and effectiveness of irinotecan. This study aimed to examine the impact of these genetic polymorphisms on irinotecan outcomes in Thai colorectal cancer patients.
MethodsThe study retrospectively analyzed 41 metastatic colorectal cancer patients treated with irinotecan-based chemotherapy. Genotyping was conducted for 23 single nucleotide polymorphisms in genes including UGT1A1, CYP3A4, CYP3A5, CES1, ABCB1, ABCC2, ABCC5, ABCG1, ABCG2, and SLCO1B1.Toxicity and efficacy were assessed, with statistical significance set at a Bonferroni-corrected P value Results
In terms of toxicity, UGT1A1*6 was significantly associated with both all-grade and severe neutropenia in the first cycle (p p p ABCC2 -24C > T variant was linked to all-grade neutropenia in the second cycle (p = 0.001). For efficacy, patients with the wild-type UGT1A1*6 had longer progression-free survival (PFS) (p SLCO1B1 521T > C variant was associated with improved PFS (p Conclusion
UGT1A1*6 and ABCC2 -24C > T variants emerge as potential predictors of irinotecan-induced neutropenia, while UGT1A1*6 and SLCO1B1 521T > C may serve as markers of prolonged PFS in Thai patients. Validation through larger prospective studies is essential to confirm and refine these genetic associations.

Increasingly frequent disruptions from diseases, disasters, and human activities pose a significant challenge to the resilience of the agri-food supply chain (AFSCRE). This study systematically explores the factors influencing AFSCRE and their mechanisms of action by integrating fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) and Interpretative Structural Modeling (ISM). Based on bibliometrics and expert interviews, a three-dimensional indicator system (12 key factors) contains flexibility, agility, and visibility. Triangular fuzzy numbers were used to process expert rating data, and combined with the Converting Fuzzy Numbers into Crisp Scores (CFCS) defuzzification method to establish a total influence matrix. The strength of the influence relationships between factors was determined through the setting of appropriate thresholds, which ultimately results in a five-layer hierarchical structure. The research results show that: level of application of digital technologies, information system maturity, information sharing and synergies, data sharing and analysis capacity and risk management capacity constitute the deep driving factors; degree of simplification of the supply chain structure and level of inventory management are the direct surface factors, presenting isolated characteristics. The study proposes resilience enhancement strategies such as supplier diversification, blockchain traceability technology embedding, and multi-body collaborative decision-making mechanisms, which provide decision support for coping with climate change and public health emergencies.Gastric cancer (GC) remains a leading cause of cancer-related mortality worldwide, with most Chinese patients diagnosed at a locally advanced stage. Neoadjuvant chemotherapy (NAC) is increasingly used to improve resectability and survival. Laparoscopy-assisted distal gastrectomy (LADG) provides short-term recovery benefits compared with open distal gastrectomy (ODG), but its safety and oncologic efficacy following NAC remain uncertain. This trial aims to determine whether LADG is non-inferior to ODG in terms of long-term survival outcomes in patients with locally advanced distal gastric cancer (LAGC) after NAC.
This is a multicentre, randomised, controlled, non-inferiority trial conducted at high-volume GC centres in China. Eligible patients (aged 18–75 years; cT3–4a, N0/+, M0) with histologically confirmed distal gastric adenocarcinoma who have completed standard NAC will be randomised 1:1 to LADG or ODG with D2 lymphadenectomy. Surgical quality will be standardised through operative manuals, intraoperative video recording and central auditing. The primary endpoint is 3-year disease-free survival. Secondary endpoints are 3- and 5-year overall survival. A total of 998 patients (499 per arm) will be enrolled, providing 80% power to test non-inferiority with an absolute 8% margin, accounting for 15% attrition. Analyses will follow the intention-to-treat principle, with Cox models used for survival comparisons and subgroup analyses according to nodal status, tumour size and pathological response.
This trial has been reviewed and approved by the Biomedical Ethics Committee of West China Hospital, Sichuan University (Approval No. 2025 (865), 16 July 2025). Written informed consent will be obtained from all participants. The results will be disseminated through peer-reviewed journals and international conferences, providing high-level evidence to guide the surgical management of LAGC after NAC.

Advance Care Planning (ACP) has the potential to enhance end-of-life care and improve the allocation of healthcare resources for patients with cancer. However, its successful implementation requires considerable effort to overcome challenges and deliver health benefits. Healthcare providers and patients are key players in ACP, and their perceptions of the process must be understood to address implementation challenges effectively.
To identify barriers and facilitators to ACP implementation in Chinese oncology settings, providing a foundation for culturally appropriate healthcare strategies.
A qualitative study guided by the Consolidated Framework for Implementation Research (CFIR). Semi-structured interviews (n = 30) were conducted between April and August 2022 to synthesise the perspectives of nurses, physicians, patients with cancer and their families who had participated in ACP. Data were analysed using a directed qualitative content analysis approach, and reporting followed the SRQR guidelines.
Twenty implementation determinants were identified across four CFIR domains, including 13 barriers and 7 facilitators. Key barriers included limited adaptability of ACP to local cultural and family norms, high complexity of ACP processes, insufficient knowledge and skills among clinicians, unclear team responsibilities, low organisational readiness, limited resources and poor public awareness. Facilitators included strong team culture, clinician motivation, supportive leadership and alignment with national policies. Two determinants showed mixed influences: the relative advantage of ACP compared to existing practices, and the extent of collaboration with external organisations.
Our study highlights the challenges of implementing ACP in China, as well as the unique and specific barriers to implementation. These findings contribute to a deeper understanding of context-specific determinants and offer actionable insights to inform the development of culturally tailored ACP implementation strategies in resource-limited healthcare settings.

ObjectivesThis study aimed to determine the preferred timing and measurement sites for electroneuronography (ENoG) to predict early recovery from acute peripheral facial paralysis.
MethodsWe retrospectively evaluated 42 patients with acute peripheral facial paralysis who received standard treatment with oral corticosteroids. The severity of facial paralysis was assessed at the initial visit and after 1 month using the House–Brackmann grading system. Patients were classified into recovery and non-recovery groups according to changes in the grade. ENoG was performed at the initial visit and after 2 weeks. ENoG amplitudes of four facial muscles (frontalis, nasalis, orbicularis oculi, and orbicularis oris) at the initial visit and after 2 weeks, as well as age, sex, affected side, and diagnosis, were compared between the two groups.
ResultsNo differences were observed in degeneration ratios across all subsites in the initial ENoG, which can be explained by the fact that Wallerian degeneration is not yet complete at this early stage. However, the second ENoG, performed after degeneration had progressed, showed significant differences across all subsites. Binary logistic regression analysis revealed that the degeneration ratio of the orbicularis oris muscle was the best predictor of early recovery (odds ratio, 0.961; p = 0.014). Receiver operating characteristic curve analysis also revealed that the degeneration ratios of all subsites measured in the second ENoG were useful in predicting early recovery, with the highest possibility at the orbicularis oris muscle (area under the curve = 0.789). When the degeneration ratio exceeded 60% in all subsites in the second ENoG, a favorable prognosis was not expected.
ConclusionThis study provides the preferred testing time and measurement sites for ENoG to predict early recovery from facial paralysis. Given the personal and social impact of facial paralysis, predicting early recovery is crucial for reassuring patients, providing better treatment, and encouraging early reintegration into society.

Parkinson’s disease (PD) is a neurodegenerative disorder characterized by dopaminergic neuron loss and neuroinflammation, with emerging roles of peripheral immune dysregulation in disease progression. This study aimed to investigate the regulatory network of CD4 + T cells in PD through multi-omics integrative analysis. Transcriptomic and miRNA datasets from peripheral blood mononuclear cells (PBMCs) of 20 PD patients and 17 healthy controls were analyzed (GSE22491, GSE100054, GSE16658). Differential expression analysis identified 287 mRNAs and 73 miRNAs (|log₂(fold change)| ≥ 0.5, false discovery rate CD4 and SEMA6A. A competing endogenous RNA (ceRNA) network was constructed, comprising 38 lncRNAs, three miRNAs (miR-155-5p, miR-27a-3p, miR-27b-3p), and their target mRNAs CD4 and SEMA6A. Four lncRNAs (including XIST, NORAD, and INE1) were identified to functionally regulate CD4. Immune cell infiltration analysis revealed increased proportions of naïve CD4 + T cells and activated dendritic cells in PD patients. CD4 expression positively correlated with γδ T cells (r = 0.48, p = 0.032) and activated NK cells (r = 0.45, p = 0.048). Gene set enrichment analysis associated CD4 with neurodegenerative pathways (e.g., Parkinson’s disease: normalized enrichment score = 1.57, p = 0.002) and oxidative phosphorylation (normalized enrichment score = 1.89, p = 7.4 × 10 ⁻ ⁶). These findings highlight a peripheral CD4 + T cell-centric ceRNA network that modulates immune-metabolic crosstalk and neuroinflammation in PD. This study provides novel insights into immune-driven neurodegeneration and suggests potential therapeutic targets for PD through metabolic-immune reprogramming.by Jin-Hwa Kim, Ji-Soo Jeong, Jeong-Won Kim, Eun-Hye Chung, Su-Ha Lee, Je-Won Ko, Youn-Hwan Hwang, Tae-Won Kim
Moutan Cortex (MC), the dried root bark of Paeonia suffruticosa, is used in traditional Chinese and Korean medicine to treat enteritis for its anti-inflammatory properties. This study compared the pharmacokinetic (PK) profiles of paeonol and paeoniflorin in normal and dinitrobenzene sulfonic acid (DNBS)-induced colitis rats, and to determine how repeated low-dose MC [MC(L), 0.5 g/kg] or high-dose MC [MC(H), 2.5 g/kg] alters PK and disease severity. Using ultra-performance liquid chromatography–tandem mass spectrometry, we found that DNBS modestly increased paeonol AUClast (NC: 247.8 ± 63.7 vs DNBS: 337.0 ± 120.8 hr*ng/mL) and decreased paeoniflorin (NC: 474.1 ± 11.7 vs DNBS: 463.7 ± 106.8 hr*ng/mL) compared to controls (ns). After repeated dosing, the maximum plasma concentration (Cmax) of paeonol was higher in the MC(H) than that in the MC(L) group (MC(L): 63.81 ± 29.74 vs MC(H): 4221.5 ± 1579.2 ng/mL, p max in the MC(H) group was also higher than MC(L) group (MC(L): 60.5 ± 15.3 vs MC(H): 164.7 ± 74.7 ng/mL, pby Xiyuan Zhu, Hongtao Dang, Xiaoyuan Jin, Xun Li
Surface defect detection of organic jujubes is critical for quality assessment. However, conventional machine vision lacks adaptability to polymorphic defects, while deep learning methods face a trade-off—deep architectures are computationally intensive and unsuitable for edge deployment, whereas lightweight models struggle to represent subtle defects. To address this, we propose Ju-LiteMobileAtt, a high-precision lightweight network based on MobileNetV2, featuring two key innovations: First, the Efficient Residual Coordinate Attention Module (EfficientRCAM) integrates spatial encoding and channel interaction for multi-scale feature capture; Second, the Cascaded Residual Coordinate Attention Module (CascadedRCAM) refines features while preserving efficiency. Experiments on the Jujube12000 dataset show Ju-LiteMobileAtt improves accuracy by 1.72% over baseline while significantly reducing parameters, enabling effective real-time edge-based jujube defect detection.The number of patients requiring wound care is increasing, placing a burden on healthcare institutions and clinicians. While negative pressure wound therapy (NPWT) use has become increasingly common, Middle East-specific wound care guidelines are limited. An in-person meeting was held in Dubai with 15 wound care experts to develop guidelines for NPWT and NPWT with instillation and dwell (NPWTi-d) use for the Middle East. A literature search was performed using PubMed, Science Direct and Cochrane Reviews. Prior to the meeting, panel members reviewed literature and existing guidelines on NPWT and/or NPWTi-d use. A wound management treatment algorithm was created. Patient and wound assessment at presentation and throughout the treatment plan was recommended. Primary closure was recommended for simple wounds, and NPWT use was suggested for complex wounds requiring wound bed preparation. NPWTi-d use was advised when wound cleansing is required, if the patient is unsuitable for surgical debridement, or if surgical debridement is delayed. When NPWTi-d is unavailable, panel members recommended NPWT. Panel members recommended NPWT for wound bed preparation and NPWTi-d when wound cleansing is needed. These recommendations provide general guidance for NPWT and NPWTi-d use and should be updated as more clinical evidence becomes available.
This study aimed to investigate the knowledge, attitudes and practices (KAP) regarding dysphagia and its care among patients with dysphagia and their caregivers.
A cross-sectional survey.
This multicentre cross-sectional study was conducted between May and September 2024. It was led by the China-Japan Friendship Hospital and involved multiple institutions, including nursing communities, nursing homes and community hospitals, located in both Beijing and Shandong Province.
Patients with clinically diagnosed dysphagia and their caregivers recruited from the China-Japan Friendship Hospital, nursing communities, nursing homes and community hospitals.
Data were collected through a self-designed questionnaire encompassing sociodemographic characteristics and three dimensions of KAP. The primary outcome was the KAP scores. Secondary outcomes included the interaction between the three KAP dimensions.
A total of 416 participants were included in the final analysis, of whom 317 (76.2%) were female. The mean scores for KAP were 12.02±8.12 (possible range: 0–24), 31.38±4.77 (possible range: 8–40) and 29.29±9.03 (possible range: 8–40), respectively. Correlation analysis indicated significant positive relationships between knowledge and attitudes (r=0.416, p=0.002), knowledge and practices (r=0.412, p
Patients with dysphagia and their caregivers demonstrated inadequate knowledge but generally positive attitudes and proactive practices towards dysphagia and its care. Adequate knowledge might be correlated with better attitudes and practices.
Minimally invasive techniques have been widely adopted for hysterectomy, including Transumbilical Laparoendoscopic Single-Site Surgery (TU-LESS) and Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES). However, their efficacy in patients with an enlarged uterus (≥280 g) remains not fully illustrated due to surgical complexity. We will compare the perioperative outcomes and recovery profiles of TU-LESS and vNOTES of this population in this study.
This single-blinded, two-arm, parallel-group, randomised controlled trial will take place in West China Second University Hospital. A total of 210 women with benign or precancerous uterine enlargement undergoing total hysterectomy (±salpingectomy/adnexectomy) will be randomised (1:1) to TU-LESS or vNOTES. The trial will span 2 years, including a follow-up of half a year. The primary outcomes will be the proportions achieving the indices of enhanced recovery after surgery respectively, including liquid diet tolerance, flatus passage, unassisted urination and mobility, during 24 hours after surgery and discharge within 2 days. Secondary outcomes include pain scores, operative duration, blood loss, complications, scar quality, analgesic use and pelvic/sexual function. Data collection occurs at baseline, perioperatively and 3/6 months postoperatively.
This study was approved by the Ethics Committee of West China Second University Hospital (2023 medical scientific research for ethical approval No.321). Written informed consent will be collected from all participants. Results will be shared through publication in peer-reviewed journals and presentations at conferences.
Children’s medical fear refers to the negative emotional experiences, including fear, anxiety and nervousness, that arise when children are confronted with medical procedures and related events during healthcare encounters. This phenomenon exerts substantial negative impacts on treatment adherence, procedural cooperation and therapeutic outcomes, thereby emerging as a critical focus in modern paediatric medicine and psychiatric care. The establishment of precise assessment protocols serves as the cornerstone for developing effective intervention strategies. Despite the proliferation of assessment instruments targeting paediatric medical anxiety, there remains a notable paucity of rigorous methodological evaluation regarding their psychometric properties and clinical utility. This systematic review aims to bridge the existing gap between theoretical frameworks and clinical application by conducting a comprehensive evaluation of measurement properties of instruments designed to assess children’s medical fear, with particular attention to their reliability, validity and clinical applicability across diverse patient populations and healthcare settings.
This study protocol has been developed in strict accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines, ensuring methodological rigour and transparency. A comprehensive search of literature will be conducted across four English databases (PubMed, Web of Science, CINAHL via EBSCOhost and PsycINFO via ProQuest) and three Chinese databases (China National Knowledge Infrastructure, WanFang Data and SinoMed) from inception to 30 September 2025. The systematic review will incorporate comprehensive evaluation of measurement instruments assessing children’s medical fear across multiple modalities, including self-report measures, observer-rated scales, behavioural observation protocols and semi-structured clinical interviews. The psychometric evaluation framework will encompass five critical domains: reliability, validity, responsiveness to clinical change, interpretability of scores and clinical utility in diverse healthcare settings. We will include primary quantitative studies published in English or Chinese.
Ethics approval will not be required. The results of this systematic review will be submitted for publication in a peer-reviewed journal.

To examine residential aged care staff's experience of death and grief, and their support needs.
A mixed-methods sequential explanatory design, using an online cross-sectional survey that included the Texas Revised Inventory of Grief and the Grief Support in Health Care Scale. Followed by semi-structured interviews with direct care workers and managers working in residential aged care homes were conducted.
Over 60% of participants experienced five or more resident deaths in the previous 12 months. Although, different levels of grief were experienced among different roles, the importance of open communication and opportunities for farewells after resident death was highlighted. Participants suggested support and education to normalise grief and promote self-care.
Recognising staff grief following the resident death is important. Providing support and education may help improve staff wellbeing and contribute to the delivery of high-quality care for both residents and their families.
Staff grief after a resident death needs to be recognised, and continuing education and support are required for their wellbeing.
The STROBE and SRQR checklists were applied.

ObjectiveRadiation-induced brain injury (RIBI) is a significant complication following radiotherapy for brain tumors, leading to neurocognitive deficits and other neurological impairments. This study aims to identify potential biomarkers and therapeutic targets for RIBI by utilizing advanced proteomic techniques to explore the molecular mechanisms underlying RIBI.
MethodsA rat model of RIBI was established and subjected to whole-brain irradiation (30 Gy). Tandem mass tagging (TMT)-based quantitative proteomics, combined with high-resolution mass spectrometry, was used to identify differentially expressed proteins (DEPs) in the brain tissues of irradiated rats. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were conducted to identify the biological processes and pathways involved. Protein-protein interaction (PPI) networks were constructed to identify key hub proteins.
ResultsA total of 35 DEPs were identified, including PHLDA3, APOE and CPE. GO enrichment analysis revealed that the DEPs were mainly involved in lipid transport, cell adhesion, and metabolic processes. KEGG analysis highlighted the enrichment of pathways related to metabolism, tight junctions, and PPAR signaling. APOE was identified as a key hub protein through PPI network analysis, indicating its potential role in RIBI pathophysiology. Immunohistochemistry further validated the increased expression of PHLDA3, APOE, and CPE in the brain tissue of irradiated rats.
ConclusionThis study provides valuable insights into the molecular mechanisms of RIBI by identifying key proteins and their associated pathways. The findings suggest that these proteins, particularly APOE and PHLDA3, could serve as potential biomarkers and therapeutic targets for clinical intervention in RIBI. These results not only enhance our understanding of RIBI’s molecular pathology but also open new avenues for the development of targeted therapies to mitigate radiation-induced neurotoxicity.

PurposeOptimal perioperative antibiotic prophylaxis in kidney transplantation remains undefined despite routine antibiotic administration to prevent infections. In this retrospective observational cohort study with historical comparison, we compared the clinical efficacy of 6 days of ampicillin/sulbactam vs. a single dose of cefazolin.
Materials and methodsWe retrospectively analyzed 2322 kidney transplantation recipients at a single center, with the evaluation period spanning from 2015 through 2021. Patients were divided into 2 groups based on the perioperative antibiotic regimen received: 971 patients received ampicillin/sulbactam, and 1351 received cefazolin. This study focused on evaluating the impact of these regimens on postoperative infection incidence and the 6-month acute rejection (AR) rates.
ResultsThe cefazolin group exhibited a tendency toward higher urinary tract infection rates within 1 month after transplantation (3.4% vs. 2.2%, p= = 0.078). There were no significant differences in surgical site infections between the groups. The 6-month AR rates were significantly lower in the cefazolin group than in the ampicillin/sulbactam group (5.1% vs. 7.9%, p= = 0.009). Cefazolin was also confirmed to be significantly associated with reduced 6-month AR rates in the multivariable logistic regression analysis (odds ratio 0.63, 95% confidence interval [0.45-0.89], p= = 0.009).
ConclusionIn this study, we observed that a single dose of cefazolin as perioperative antibiotic prophylaxis may lead to higher rates of postoperative urinary tract infections, but it could potentially lower the incidence of acute rejection within six months.
Post-induction hypotension (PIH) is a critical concern in elderly surgical patients and is associated with adverse postoperative outcomes. This trial aims to compare the effects of propofol, etomidate and remimazolam on the incidence of PIH in older adults undergoing non-cardiac surgery.
In this single-centre, triple-arm, randomised controlled trial, 210 patients aged ≥80 years with American Society of Anaesthesiologists physical status I–III undergoing elective non-cardiac surgery will be recruited. All patients will receive general anaesthesia with endotracheal intubation. Patients will be randomised (1:1:1) to receive propofol, remimazolam or etomidate for anaesthesia induction (n=70 per group). The primary outcome is the incidence of PIH (mean arterial pressure (MAP) 30% from baseline, vasopressor requirements, bradycardia, injection pain, myoclonus, postoperative delirium, and cardiac, cerebral and renal complications during hospitalisation.
This trial was approved by the Ethics Committee of the First Affiliated Hospital of Soochow University (Approval No. 2024-380). The results will be peer-reviewed for publication in a scientific journal.
