OBJECTIVE To evaluate the cost-effectiveness of cefiderocol versus best available therapy (BAT) or standard-of- care (SOC) for the treatment of confirmed or suspected carbapenem-resistant Gram-negative bacterial (CRGNB) serious infections from the perspective of the Chinese healthcare system, and to explore its reasonable pricing. METHODS A decision tree model was constructed based on data from two phase Ⅲ clinical trials (CREDIBLE-CR and GAME CHANGER) to simulate the cost- effectiveness of cefiderocol in two scenarios: salvage therapy for confirmed CRGNB infection (scenario 1) and empirical therapy for suspected CRGNB infection (scenario 2). The primary outcome measure was the incremental cost-effectiveness ratio (ICER). The willingness-to-pay (WTP) was set at 1 to 3 times China’s per capita GDP in 2024. To verify the robustness of the results, one- way and probabilistic sensitivity analyses were conducted, and based on these, a reasonable price range for cefiderocol in the Chinese market was explored. RESULTS The results for scenario 1 showed that the clinical cure rate in the cefiderocol group was higher than that in the BAT group (47.50% vs. 34.21%), but its ICER was 415 065.03 yuan per cured case, exceeding three times China’s GDP per capita. Scenario 2 revealed that the ICER for cefiderocol relative to SOC was as high as 1 362 446.16 yuan per cured case, far exceeding the WTP. Sensitivity analysis indicated that the treatment duration and price of cefiderocol were key factors affecting its cost-effectiveness. In the two scenarios described above, the unit price of cefiderocol must fall below 683.47 and 242.00 yuan/g, respectively, to be considered cost-effective. CONCLUSIONS Based on the current market price, cefiderocol lacks sufficient cost-effectiveness for treating confirmed or suspected CRGNB serious infections within China’s healthcare system. To improve its accessibility, price negotiations or a tiered medical insurance payment strategy are required.

Tenosynovial giant cell tumor (TGCT) is a rare mesenchymal tumor that clinically presents as nodular-type or diffuse-type (D-TGCT). D-TGCT is more aggressive, has a higher surgical recurrence rate, and can potentially lead to severe joint destruction. The traditional treatment is primarily through surgical intervention. Recent advancements in understanding the molecular mechanisms of the disease and the development of new drugs have significantly changed TGCT treatment strategies. Drug therapy and active surveillance have become important treatment options for unresectable or high-recurrence-risk TGCT. Imaging examinations and patient-reported outcome tools play a crucial role in evaluating efficacy and guiding treatment decisions. Comprehensive management by a multidisciplinary team and utilizing individualized treatment plans can significantly improve the quality of life and treatment outcomes of patients. Future research should explore the molecular mechanisms of TGCT, enhance multidisciplinary collaboration, and emphasize long-term management to improve treatment efficacy and patient prognosis.

Objective:
To investigate the influencing factors for cognitive function among aluminum workers, so as to provide the basis for intervention and prevention of cognitive function among aluminum-exposed populations.
Methods:
From July to August 2019, male aluminum workers in the electrolytic aluminum workshop of an aluminum factory in Shanxi Province were selected using the cluster sampling method. Demographic information, prevalence of chronic diseases, lifestyle behaviors, night shifts, and sleep quality were collected through questionnaire surveys. Blood aluminum levels were measured using inductively coupled plasma-mass spectrometry. Cognitive function was investigated using the Montreal Cognitive Assessment. Factors affecting cognitive function among aluminum workers were analyzed by a quantile regression model.
Results:
A total of 142 aluminum workers were surveyed, including 57 workers aged 20 to <40 years (40.14%) and 85 workers aged 40 to 60 years (59.86%). The median blood aluminum level was 38.23 (interquartile range, 21.82) μg/L. The median cognitive function score was 24.00 (interquartile range, 3.00) points. Quantile regression analysis revealed that older age (βQ5=-0.186, 95%CI: -0.269 to -0.102), lower educational level (βQ5=1.933, 95%CI: 1.029 to 2.838; βQ10=1.743, 95%CI: 0.480 to 3.006; βQ50=1.038, 95%CI: 0.141 to 1.935; βQ75=1.006, 95%CI: 0.437 to 1.575; βQ90=1.111, 95%CI: 0.291 to 1.930), smoking (βQ5=-2.056, 95%CI: -3.264 to -0.849), alcohol consumption (βQ5=-1.821, 95%CI: -3.247 to -0.396) and higher blood aluminum level (βQ5=-0.075, 95%CI: -0.110 to -0.040; βQ10=-0.078, 95%CI: -0.127 to -0.029; βQ50=-0.075, 95%CI: -0.110 to -0.040; βQ75=-0.057, 95%CI: -0.079 to -0.035; βQ90=-0.067, 95%CI: -0.099 to -0.035) were associated with cognitive function decline among aluminum workers.
Conclusions
Educational level and blood aluminum level are the main factors affecting the cognitive function among aluminum workers. Among those with lower cognitive function scores, age, smoking and alcohol consumption are also associated with cognitive function.

Autism Spectrum Disorder (ASD) is marked by early-onset neurodevelopmental anomalies, yet the temporal dynamics of genetic contributions to these processes remain insufficiently understood. This study aimed to elucidate the role of the Shank3 gene, known to be associated with monogenic causes of autism, in early developmental processes to inform the timing and mechanisms for potential interventions for ASD. Utilizing the Shank3B knockout (KO) mouse model, we examined Shank3 expression and its impact on neuronal maturation through Golgi staining for dendritic morphology and electrophysiological recordings to measure synaptic function in the anterior cingulate cortex (ACC) across different postnatal stages. Our longitudinal analysis revealed that, while Shank3B KO mice displayed normal neuronal morphology at one week postnatal, significant impairments in dendritic growth and synaptic activity emerged by two to three weeks. These findings highlight the critical developmental window during which Shank3 is essential for neuronal and synaptic maturation in the ACC.

Background Some studies have suggested that exposure to multiple metals is closely linked to the development of metabolic syndrome (MS) in the populations, but the effect of aluminum exposure on MS remains unclear. Objective To analyze the prevalence and influencing factors of MS among employees with aluminum exposure in Shanxi Province. Methods Cluster sampling was employed to survey male frontline workers in an aluminum factory in Shanxi Province. Data on general demographic information, lifestyle, occupational history, medical history, and family history of chronic diseases were collected through questionnaires. The concentration of fasting blood glucose was determined using the glucose oxidase technique, and blood lipid levels were determined using the peroxidase method. Serum aluminum levels were detected using inductively coupled plasma-mass spectrometry (ICP-MS), and blood biochemical indicators were measured using the peroxidase method. Based on the China's 2020 diagnostic criteria for MS, the participants were and divided into an MS group anda non-MS group. Variables with statistical significance in univariate analysis were included to construct a logistic regression model. Results A cohort of 312 workers participated in this research, with 84 individuals diagnosed with MS, yielding a prevalence rate of 26.92%. The logistic regression model revealed that body mass index (BMI)≥24.0 kg·m−2 (OR=1.967, 95%CI: 1.057, 3.659), alcohol consumption (OR=1.883, 95%CI: 1.063, 3.336), experiencing major life event (OR=3.886, 95%CI: 1.509, 10.008), family history of hypertension (OR=2.112, 95%CI: 1.162, 3.837), serum aluminum concentration (OR=1.024, 95%CI: 1.012, 1.035), alanine aminotransferase (ALT) level (OR=1.032, 95%CI: 1.011, 1.054), and white blood cell (WBC) count (OR=1.210, 95%CI: 1.001, 1.465) were significant influencing factors for MS. Conclusion BMI≥24.0 kg·m−2, alcohol consumption, experiencing major life event, family history of hypertension, elevated serum aluminum concentration, increased ALT level, and elevated WBC count are risk factors for MS among occupationally aluminum-exposed workers.

Objective:To analyze the causes and demographic characteristics of pre-engraftment mortality in patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) and investigate the risk factors and measures for preventing pre-engraftment mortality.Methods:A retrospective case analysis, involving a total of 7 427 patients who underwent allo-HSCT at Peking University People’s Hospital between January 2016 and July 2023, was conducted.Results:Among the 7 427 patients who underwent allo-HSCT, 56 cases (0.75% ) experienced pre-engraftment mortality. The median time to death for these 56 patients was +7 (-3 to +38) days after stem cell infusion. The median times to death for patients with acute leukemia (AL), severe aplastic anemia (SAA), and myelodysplastic syndrome (MDS) were +11 (-1 to +38), +3 (-1 to +34), and +16 (-1 to +38) days, respectively ( P=0.013). The main causes of pre-engraftment mortality were infection (39.3% ), cardiac toxicity (28.6% ), and intracranial hemorrhage (26.8% ). Infection was the most common cause of pre-engraftment mortality in patients with AL and MDS (55.0% and 60.0% ), whereas cardiac toxicity was predominantly observed in patients with SAA (71.4% ), with no cases in patients with AL and only one case in patients with MDS. Among patients who died from intracranial hemorrhage, 53.3% had severe infections. The median times to death for infection, cardiac toxicity, and intracranial hemorrhage was +11 (-1 to +38), +2.5 (-1 to +17), and +8 (-3 to +37) days, respectively ( P<0.001) . Conclusions:Infection is the primary cause of pre-engraftment mortality in allo-HSCT, and severe cardiac toxicity leading to pre-engraftment mortality should be closely monitored in patients with SAA.

Objective:To investigate the efficacy and safety of liposomal amphotericin B (L-AmB) for the salvage treatment of invasive fungal disease (IFD) in patients with hematological diseases.Methods:Data were retrospectively collected from 80 patients with hematological issues treated with L-AmB between June 2023 and December 2023 after failure of previous antifungal therapy. Baseline patient information, clinical efficacy, and factors affecting the efficacy of L-AmB were analyzed by logistic regression. Moreover, adverse effects associated with L-AmB were evaluated.Results:Among the 80 patients, 9 (11.2%) had proven IFD, 43 (53.8%) had probable IFD, and 28 (35.0%) had possible IFD. The efficacy rate of L-AmB salvage therapy for IFD was 77.5%, with a median daily dose of 3 (range: 1-5) mg·kg -1·d -1 and a median dosing course of 14 (range: 8-25) days. Multivariate logistic regression analysis showed that the disease remission status ( OR=4.337, 95% CI 1.167-16.122, P=0.029) and duration of medication ( OR=1.127, 95% CI 1.029-1.234, P=0.010) were independent factors affecting the efficacy of L-AmB. The incidence of infusion reactions associated with L-AmB, including fever and chills, was 5.0%. The incidence of hypokalemia was 28.8% (predominantly grades 1-2), and the incidence of nephrotoxicity was 11.3% (predominantly grades 1-2) . Conclusion:L-AmB is safe and effective in the treatment of patients with IFD who are intolerant to or who have experienced no effect of previous antifungal therapy, with a low rate of adverse reactions.

Objective:To evaluate the safety of patients with hepatic adenoma undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:A retrospective analysis of the clinical characteristics and prognosis of eight patients with hepatic adenoma who underwent allo-HSCT in the Hematology Department of Peking University People’s Hospital from January 2010 to March 2024 was conducted.Results:Of the eight patients who underwent allo-HSCT with hepatic adenoma, one patient was considered MDS-h transfusion-dependent and seven had aplastic anemia. The median age of the patients was 23 years (13-48 years). The median time from the diagnosis of AA or MDS to transplantation was 14 years (6-24 years), whereas the median time from taking androgens to diagnosing hepatic adenoma was 9 years (5-13 years). Six cases underwent haplo-HSCT, one case underwent matched unrelated donor HSCT, and one case underwent matched related donor HSCT. All patients achieved neutrophil engraftment at a median time of 11.5 days (11-20 days) and PLT engraftment within 60 days at a median of 19 days (10-37 days) after haplo-HSCT. Moreover, seven patients developed CMV anemia after transplantation, three patients had hemorrhagic cystitis, and two patients developed acute GVHD. During and after transplantation, eight patients did not show severe liver function damage or rupture of hepatic adenoma. In relation to imaging size, four patients showed varying degrees of reduction in hepatic adenoma size after transplantation, whereas four patients did not show significant changes in hepatic adenoma size after transplantation. The median follow-up time was 540.5 (30-2 989) days. Of the eight patients, six survived and two died. Furthermore, no direct correlation was observed between death and hepatic adenoma.Conclusion:Patients with hepatic adenomas undergoing allo-HSCT are not contraindications for transplantation, which will not increase transplant-related mortality.
