INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Multimodal MRI has played an important role in the screening, diagnosis and treatment evaluation of MMD. This article reviews the research progress of multimodal MRI in MMD from aspects of vascular morphology, hemodynamics, microstructural damage of brain tissues and brain functional networks, aiming to provide references for MMD diagnosis and treatment.

Knee osteoarthritis (KOA) is a common chronic degenerative disease that not only causes pain and reduces the quality of life for patients but also imposes a significant societal burden. Clinical pathways can be developed by referencing recommendations from clinical practice guidelines to localize guidelines within the context of integrated traditional Chinese and western medical systems. However, existing clinical pathways suffer from shortcomings such as deficiencies in integrated traditional Chinese and western medical diagnosis and treatment, inadequate shared decision-making between healthcare providers and patients, and suboptimal visualization of clinical pathways. This study aimed to address and optimize the clinical pathway of KOA by comprehensively organizing and localizing the recommended guidelines. The concept of integrated traditional Chinese and western medicine was reflected through the construction of a path of joint decision-making between doctors and patients, emphasizing the coexistence of diagnosis and screening, the combination of clinical and imaging staging, joint decision-making between doctors and patients, and treatment stages. This pathway emphasizes patient-centered approach, with pain relief and functional rehabilitation running parallel, achieving the implementation of evidence-based concepts in practical medical practice. It provides a concrete basis for joint decision-making between doctors and patients in the integrated treatment of KOA with traditional Chinese and western medicine, which helps to improve diagnosis and treatment efficiency and patient quality of life.

Objective:To conduct a thorough analysis of the clinical characteristics in patients with trisomy 8 syndrome and autoimmune diseases, and to provide a new perspective on the diagnosis and management of the fever of unknown origin (FUO).Methods:Patients who were admitted to Huashan Hospital, Fudan University between July 1st, 2021 and May 1st, 2024 for FUO and subsequently diagnosed with trisomy 8 syndrome with autoimmune diseases were included. In this retrospective cohort study, patients were divided into infection and non-infection group according to the etiological evidence, and the clinical characteristics and treatments were collected and compared between the two groups. Statistical analysis was performed using the Mann-Whitney U test. Results:Among the nine enrolled patients, one case was associated with Behet syndrome (BD) without myelodysplastic syndrome (MDS) and without co-occurring infection, eight cases were associated with MDS, among which six cases had both BD and MDS, one case had allergic pneumonia, and one case had rheumatoid arthritis. Six MDS cases had infections. The C-reactive protein (CRP) level in the infection group was significantly higher than that in the non-infection group(72.39(14.62, 132.70) mg/L vs 3.68(2.30, 10.09) mg/L; Z=1.00, P=0.048). There were no statistically significant differences in other inflammatory markers (such as white blood cell count, platelet count, erythrocyte sedimentation rate, ferritin, and neutrophil CD64 index) between the infection and non-infection groups (all P>0.05). In the infection group, one had bacterial infection, five had fungal infections, including two cases of disseminated aspergillosis, one case of mixed bacterial, fungal, and viral infections, one case of mucormycosis combined with Enterococcus faecalis infection, and one case of pulmonary aspergillosis combined with disseminated Mycobacterium abscessus infection. Among the nine patients, eight patients received immunosuppressive treatment centered on the glucocorticoids and (or) thalidomide, and all six infected patients received the above immunosuppressive treatment based on the anti-infection therapy. Eight of the nine cases were stable and followed up regularly, while one case died due to worsening of illness. Conclusions:Autoimmune diseases associated with trisomy 8 syndrome is rare. In addition to anti-infection treatment, glucocorticoids, thalidomide or other immunosuppressive drugs should be administrated to suppress the inflammatory response in patients with co-infection, and the disease could be well controlled.

Objective:To investigate the clinical value of adjuvant therapy after conversion resection for pancreatic cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 173 patients with pancreatic cancer who underwent surgical resection after neoadjuvant and/or induction therapy in The First Affiliated Hospital of Naval Medical University from January 2019 to December 2021 were collected. There were 107 males and 66 females, aged (59±9)years. Observation indicators: (1) comparison of clinicopathological data between patients with and without adjuvant therapy after conversion resection for pancreatic cancer; (2) analysis of influencing factors for prognosis of pancreatic cancer after conversion resection; (3) follow-up and prognosis; (4) survival benefit of adjuvant therapy in subgroup populations. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the non-parameter rank sum test. The Graphpad prism 8 software was used to draw survival curves, the Kaplan-Meier method was used to calculate survival time and survival rates, and the Log-Rank test was used for survival analysis. The COX proportional hazards regression model was used for univariate and multivariate analyses. Interaction analysis was used to determine the benefit of adjuvant therapy in subgroup populations. Results:(1) Comparison of clinicopathological data between patients with and without adjuvant therapy after conversion resection for pancreatic cancer. Of the 173 pancreatic cancer patients, there were 108 cases with adjuvant therapy after conversion resection and 65 cases without adjuvant therapy after conversion resection, respectively. Age and body mass index were (58±9)years and (23.2±2.8)kg/m 2 in patients with adjuvant therapy, versus (61±8)years and (22.2±2.8)kg/m 2 in patients without adjuvant therapy, showing significant differences in the above indicators between them ( t=-2.036, 2.200, P<0.05). (2) Analysis of influencing factors for prognosis of pancreatic cancer after conversion resection. Results of multivariate analysis showed that CA19-9 normalization, pathological N staging, degree of tumor differentiation and postoperative adjuvant therapy were independent factors influencing overall survival time in pancreatic cancer patients receiving conversion resection ( hazard ratio=1.598, 1.541, 2.004, 2.571, 95% confidence interval as 1.041-2.453, 1.021-2.327, 1.288-3.118, 1.721-3.843, P<0.05). (3) Follow-up and prognosis. All 173 patients were followed up for 24.5(5.0,52.0)months. The postoperative median overall survival time of 173 patients was 28.9(5.7,51.9)months, and the 1-, 2-, 3-year overall survival rates were 90%, 59%, 40%, respectively. Of 2019, 2020, 2021, the proportions of patients receiving adjuvant therapy after conversion resection were 62.8%(27/43), 57.7%(30/52) and 65.4%(51/78) respectively. The postoperative median overall survival time was 42.2(8.8,49.7)months in patients with adjuvant therapy after conversion resection, versus 20.4(5.7,51.9)months in patients without adjuvant therapy after conversion resection, showing a significant difference between them ( χ2=29.893, P<0.05). (4) Survival benefit of adjuvant therapy in subgroup populations. Results of interaction analysis showed that in subgroup populations with CA19-9 normalization, pathological stage N0, pathological stage N1-2, moderate to well differentiated tumors, adjuvant therapy after conversion resection can bring a better survival benefit for patients with pancreatic cancer ( adjustment hazard ratio=0.220, 0.300, 0.410, 0.340, 95% confidence interval as 0.120-0.400, 0.170-0.560, 0.240-0.690, 0.210-0.690). Conclusions:Postoperative adjuvant therapy is an independent factor influencing overall survival time in pancreatic cancer patients receiving conversion resection. Adjuvant therapy after conversion resection can bring additional survival benefits for pancreatic cancer, particularly for patients who respond favorably to neoadjuvant and/or induction therapy.
