Objective To evaluate the cost-effectiveness of roxadustat and darbepoetin alfa on treating renal anemia in dialysis-dependent chronic kidney disease(DD-CKD)patients,thus providing health economics reference for treatment of renal anemia.Methods A Markov model simulating the development and treatment of anemia in DD-CKD patients in a lifetime horizon(20 years)was constructed.Total costs of roxadustat and darbepoetin alfa injection were estimated from the perspective of Chinese healthcare system,with health outcomes converted into quality-adjusted life year(QALY).The incremental cost-effectiveness ratio(ICER)was used to describe the results.The willingness-to-pay(WTP)threshold was set at 257 094 yuan,which was three times China's gross domestic product(GDP)per capita in 2023.Sensitivity analyses were performed to test the uncertainties of the results.Results The total treatment costs of roxadustat and darbepoetin alfa injection were 111 902.41 yuan and 52 927.92 yuan respectively,corresponding to QALY values of 4.76 and 4.74 life-years.The incremental cost-effectiveness(ICER)was 2 654 912.45 yuan/QALY,which exceeded 3 times GDP per capita.Therefore,compared with darbepoetin alfa injection,roxadustat has no cost-effectiveness for patients with DD-CKD.Conclusion In the context of current economic development in China,darbepoetin alfa injection is more cost-effective than roxadustatin for treating anemia in DD-CKD patients.

Objective:This study aimed to evaluate the global research landscape, identify trends, and determine hotspots concerning hepatoma recurrence post-liver transplantation.Methods:We conducted a bibliometric analysis usinga systematic search was conducted in the Web of Science Core Collection database from Jan. 1992 to Oct. 2023 to identify relevant articles on hepatoma recurrence after liver transplantation. Articles were selected based on inclusion and exclusion criteria and analyzed for publication trends by country/region, journal, author, institution, citation, and keyword. Visualization tools such as Citespace, VOSviewer, and Bibliometric.com were utilized for statistical analysis, identification of emerging trends, and clustering of keyword co-occurrence.Results:Out of 4,936 articles retrieved, 1,189 were included in the final analysis. There was a notable increase in publications on hepatoma recurrence following liver transplantation from 1992 to 2021, peaking in 2021 both globally (n=103) and nationally (n=32). China has the largest number of publications in this field (n=308), maintaining significant collaboration with the United States, South Korea, Japan, Canada. 'Liver Transplantation’ journal had the highest number of publications (n=113). Zhejiang University was the leading institution (n=74), with Academician Zheng Shusen being the most prolific scholar (n=76 publications). Citation emergence detection found that Italian scholar Mazzaferro's Predicting survival after liver transplantation in patients with hepatocellular carcinoma beyond the Milan criteria: a retrospective, exploratory analysis published on The Lancet Oncology in 2009 had the highest burst strength (36.98). Five bursting keywords were identified: alpha fetoprotein, model, validation, sorafenib, and risk. Cluster analysis of keyword co-occurrence revealed five primary research themes: the medication for hepatocellular carcinoma recurrence after liver transplantation, recipient selection criteria, prognostic factors, development and validation of recurrence prediction model, and local treatments for hepatocellular carcinoma.Conclusions:The study underscores rapid advancements in the research on hepatocellular carcinoma recurrence post-liver transplantation over the past three decades, with significant contributions from Chinese scholars, particularly from Zhejiang University and Academician Zheng Shusen. The evolving research hotspots have shifted from transplantation experiences and recipient selection criteria to early post-transplant recurrence risk prediction and therapeutic strategy development.

Objective:To explore health utility value, evaluate health-related quality-of-life(QOL)of pediatric liver transplantation(LT)recipients and examine its influencing factors to provide rationales for related health economic evaluations.Methods:This cross-sectional QOL was conducted through a questionnaire in pediatric LT recipients aged 5-17 years.The interviewees undergoing initial LT from June 2013 to September 2021 were reviewed regularly.Those children and their parents unwilling to participate or failing to understand the contents of questionnaire were excluded.The questionnaire was designed on the basis of Child Health Utility 9D Instrument(CHU9D)and answered online by one of primary caregiver.Chinese score system of CHU9D was employed for converting the responses into health utility values and the influencing factors were analyzed.Univariate analysis was performed by nonparametric tests and multivariate analysis by multiple linear regression model. P<0.05 was deemed as statistically significant. Results:A total of 140 valid questionnaires were obtained.Mean age of pediatric LT recipients was(7.95±2.74)years and mean postoperative time(4.90±2.17)years.Among them, 19 cases had experienced acute rejection and 101(72.1%)cases were living-related LT recipients.CHU9D scale indicated that average health utility value was(0.85±0.14)points.Univariate analysis revealed that age( P=0.008), education level( P<0.001)and primary disease( P=0.010)influenced the postoperative level of QOL.Multivariate analysis indicated that QOL was correlated with education level(behind schedule: 95% CI: -0.146, -0.034, P=0.002; leave of absence: 95% CI: -0.251, -0.068, P=0.001). Conclusions:Health utility of pediatric LT recipients is high with an excellent QOL.Poor QOL is associated with absence from school or dropping out of school.

Objective:To explore the international research hotpots and development trend of therapeutic drug monitoring (TDM).Methods:Web of Science database was searched as of February 16, 2022, with search term of "therapeutic drug monitoring" or "drug monitoring". The research articles on TDM were collected and analyzed for the annual publication amount, countries, authors, and institutions. Citation burst was detected using CiteSpace software, and keywords-cluster was carried out by VOSviewer to visually show the research hotpots.Results:A total of 2 318 articles were included, and the first one was published in 1975. The United States published the largest amount of related articles and had the closest cooperation with other countries. University of Queensland in Australia was the institution with the most publications, and Roberts JA was the author with the most publications. A total of 10 citation bursts were detected, and 6 keywords-clusters related to TDM were found by cluster analysis method. Recent international research hotspots included TDM of biologics in patients with inflammatory bowel disease, TDM of anti-infective drugs in critically ill patients, and TDM of anti-tumor drugs.Conclusions:Referring to the international research hotspots, TDM should be carried out for more drugs, such as infliximab, adalimumab, and imatinib, etc., to provide personalized and precise medication care for patients and improve the safety of drug therapy.
