Economic burden of patients with advanced non-small-cell lung cancer receiving nivolumab versus chemotherapy in China.

Aim: As new treatment patterns are gradually being used in patients with non-small-cell lung cancer, it is necessary to have a better understanding of real-world data on clinical practices and their potential impact on healthcare resource utilization (HCRU). Patients & methods: A retrospective observational study was conducted with electronic medical records from Shanghai Chest Hospital. Hospitalized patients treated with nivolumab or second-line chemotherapy were included. Results: A total of 296 patients were included in this study, of whom 187 were treated with nivolumab. About 74.33% received nivolumab monotherapy at different doses. The mean cost of nivolumab was $3334.14 (±86.69). Nivolumab decreased inpatient days to 1.9545 days with a more stable cost and HCRU per cycle. Conclusion: Nivolumab is expensive but it reduces other HCRU.

Anisodamine Ameliorates Hyperkalemia during Crush Syndrome through Estradiol-Induced Enhancement of Insulin Sensitivity.

Hyperkalemia is a major cause of on-site death in crush syndrome (CS), which is more severe and common in male victims. Anisodamine is a belladonna alkaloid and widely used in China for treatment of shock through activation of α7 nicotinic acetylcholine receptor (α7nAChR). The present work was designed to study the protective effect of anisodamine in CS and the possible role of estradiol involved. Male and ovariectomized female CS mice exhibited lower serum estradiol and insulin sensitivity, and higher potassium compared to the relative female controls at 6 h after decompression. There was no gender difference in on-site mortality in CS mice within 24 h after decompression. Serum estradiol increased with similar values in CS mice of both gender compared to that in normal mice. Anisodamine decreased serum potassium and increased serum estradiol and insulin sensitivity in CS mice, and methyllycaconitine, selective antagonist of α7nAChR, counteracted such effects of anisodamine. Treatment with anisodamine or estradiol increased serum estradiol and insulin sensitivity, decreased serum potassium and on-site mortality, and eliminated the difference in these parameters between CS mice received ovariectomy or its sham operation. Anisodamine could also increase blood pressure in CS rats within 3.5 h after decompression, which could also be attenuated by methyllycaconitine, without influences on heart rate. These results suggest that activation of α7nAChR with anisodamine could decrease serum potassium and on-site mortality in CS through estradiol-induced enhancement of insulin sensitivity.

Health state utilities in patients with advanced non-small-cell lung cancer in China.

AIM: Non-small-cell lung cancer (NSCLC) is a leading global health threat that impairs patient health outcomes. Health state utilities are fundamental values in economic evaluation and significantly vary across countries. Given the scarce data on the Chinese population, the current study measured utility values in the Chinese patients with NSCLC. METHODS: This study was conducted as a cross-sectional survey of patients with advanced NSCLC at the Shanghai Chest Hospital. Utility values were assessed using the EuroQol five-dimension (EQ-5D) instrument and scored based on the Chinese-specific value algorithm. Predictors of utility values were examined using a subgroup analysis and a multiple regression model. RESULTS: The mean EQ-5D utility value of recruited patients was 0.814. The regression analysis revealed that tumor stage, treatment regimen and line of therapy were the potential predictors of utility values. CONCLUSION: This study provides the Chinese-specific health utility data for advanced NSCLC using the EQ-5D.
