ObjectiveThe combination of pembrolizumab and chemotherapy has demonstrated notable clinical advantages in improving overall survival than chemotherapy alone for patients with untreated advanced pleural mesothelioma. The purpose of this study was to assess its cost-effectiveness.Materials and methodsA Markov state-transition model was constructed using data from the IND227 phase 3 randomized clinical trial. Utility values for health states were taken from the IND227 trial, and direct medical costs were from the pertinent literature and local pricing data. Outcomes measured included quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER), incremental net health benefit (INHB), and incremental net monetary benefit (INMB). To manage the uncertainty in the model, both probabilistic sensitivity analysis (PSA) and one-way sensitivity analysis (OWSA) were used.ResultsIn the base-case analysis, pembrolizumab plus chemotherapy resulted in an incremental gain of 0.23 QALYs at an additional cost of $18,199.63, resulting in an ICER of $80,557.23/QALY. This was not favorable compared to China’s willingness-to-pay (WTP) threshold of $38,042.49/QALY, with an INHB of −0.25 QALYs and an INMB of $-9,605.00. Subgroup analyses showed ICERs for pembrolizumab plus chemotherapy versus chemotherapy of $33,917.61 and $99,536.73 in non-epithelioid and epithelioid patients, respectively. PSA indicated probabilities of cost-effectiveness for pembrolizumab plus chemotherapy at 0.55%, 69.41%, and 0.14% for the entire population and the non-epithelioid and epithelioid subgroups, respectively.ConclusionIn the Chinese healthcare system, the combination of pembrolizumab and chemotherapy did not prove to be more cost-effective than chemotherapy alone as an initial treatment for untreated advanced pleural mesothelioma, with the exception of patients who have non-epithelioid histology.

Backgrounds: Our study aimed to identify and predict patients with heart failure (HF) taking novel-dose Sacubitril/Valsartan (S/V) at risk for all-cause readmission, as well as investigate the possible role of left ventricular reverse remodeling (LVRR). Methods and results: There were 464 patients recruited from December 2017 to September 2021 in our hospital with a median follow-up of 660 days (range, 17-1494). Competing risk analysis with Gray's Test showed statistically significant differences in all-cause readmission ( p -value

Abstract Background Isolated distal deep vein thrombosis (IDDVT), a disease frequently detected in hospitalized patients, can progress to proximal deep vein thrombosis (PDVT) and pulmonary embolism (PE). Here, we evaluated the effects of anticoagulation in hospitalized IDDVT patients. Methods We conducted a retrospective study in our hospital and enrolled hospitalized IDDVT patients diagnosed by compression ultrasonography (CUS) from January to December 2020. Participants were divided into anticoagulation (AC) and non-anticoagulation (non-AC) groups. After propensity score matching (PSM), multivariate Cox regression analyses were performed to assess whether anticoagulation was associated with PDVT/PE, and all-cause mortality. Results A total of 426 IDDVT inpatients with CUS follow-up were screened from 1502 distal DVT patients and finally enrolled. The median age was 67 years with 51.4% males and 15.5% cancer patients. The median follow-up was 11.6 months. There were 288 and 138 patients treated with or without anticoagulants, respectively. Patients in the non-AC group had less body mass index and more comorbidities. Patients in the AC group were treated with rivaroxaban or dabigatran (52.1%), low molecular weight heparin (42.7%), and warfarin (5.2%). The PSM generated 111 pairs of well-matched IDDVT patients with or without anticoagulation. The Kaplan–Meier analysis demonstrated that neither the incidence of PDVT/PE (5.4% vs. 2.7%, log-rank p = 0.313) nor all-cause mortality (27.9% vs. 18.9%, log-rank p = 0.098) was significant different between groups. Anticoagulation was not associated with PDVT/PE and all-cause mortality in the multivariable Cox regression analyses using the matched cohorts. The main risk factors for all-cause mortality were age, malignancy history, BMI, sepsis, heart failure, and white blood cell (WBC) count. Conclusions In hospitalized IDDVT patients, the thrombosis extension rate to PDVT/PE was low. Anticoagulation did not reduce the incidence of thrombosis extension of IDDVT and was not associated with all-cause mortality.

Dilated cardiomyopathy (DCM) has brought great damage to the patients' health and social economy. The number of patients with recovered dilated cardiomyopathy (recDCM) has increased over the years as treatment progresses. However, there is a lack of relevant evidence to support the clinical management of patients with recDCM, thereby, the recommendations in guidelines remains sparse. Accordingly, the exploration of recDCM is important to improve patient prognosis and reduce societal burden. This is an open-label, randomized controlled, prospective study that will compare the safety and efficacy of original dose and halved dose of neurohumoral blockades for patients with recDCM.MethodsAn open-label, randomized controlled, prospective study will be conducted among eligible patients with recDCM. During the pilot study phase, we will recruit 50 patients. The primary endpoint is hospitalization for heart failure or heart failure relapse within 12 months. Secondary endpoint is major adverse cardiovascular events, including cardiovascular mortality, myocardial infarction, stroke, sustained atrial tachycardia, or ventricular tachycardia. The results will be analyzed using intention-to-treatment analysis.DiscussionThe study will provide important evidence of whether it is safe and effective to halve the dosage of neurohumoral blockades in recDCM patients.Trial registration numberChiCTR2100054051 (www.chictr.org.cn)
