Flecainide is a class IC antiarrhythmic drug that is contraindicated in patients who have a history of myocardial infarction, but its effect on mortality and risk of proarrhythmia in patients with stable obstructive and nonobstructive epicardial coronary artery disease (CAD) has not been assessed. We sought to compare the safety of flecainide administration in patients who had angiographic evidence of either no or minimal CAD versus nonobstructive CAD, and those who underwent nuclear stress testing with perfusion defects versus those without perfusion defects. We conducted a retrospective chart review of 348 patients who were treated with flecainide for at least 1year duration and underwent evaluation for CAD with coronary angiography or myocardial perfusion imaging (MPI) stress testing within 3 months of initiating flecainide. We compared overall mortality and proarrhythmia between varying levels of CAD and perfusion defects. There was a similar 10-year survival between those with no or minimal CAD, nonobstructive CAD, and obstructive CAD (p=0.6). Additionally, there was no difference in arrhythmia burden, including sustained ventricular tachycardias or frequent premature ventricular contractions (> 5% daily burden; p=0.25). There was also no increase in mortality among those who had reversible perfusion defects >0% compared with those without, among subjects who underwent MPI (p=0.14). On subgroup analysis, there was no increased risk in all-cause mortality with any specific coronary artery involvement, or with obstructive multivessel CAD (p=0.89). Flecainide use is not associated with an increase in either all-cause mortality or ventricular arrhythmias in low-risk patients with stable nonobstructive CAD. Flecainide use is not associated with an increase in either all-cause mortality or ventricular arrhythmias in low-risk patients with stable nonobstructive CAD. For patients taking factor Xa (FXa) inhibitors who have life-threatening bleeding, emergency surgery, drug interactions, etc., a rapid and precise assay is needed to monitor for potential medication failure, to assess safety during periprocedural anticoagulation management, and to manage the care of chronically anticoagulated patients. Anti-factor Xa (anti-Xa) activity assays have been recommended in guidelines, but the evaluation of different calibrations of anti-Xa activity assays and the data on the recommended range are still limited, especially in the Asian population. This is a nationwide multicenter methodology exploratory study in an Asian population, including nine hospitals from Beijing, Shanghai, Liaoning, Shandong, Jiangsu, Anhui, Henan, Chongqing, and Fujian. A total of 485 healthy volunteers and 219 patients taking rivaroxaban or apixaban (single dose) were enrolled in the study. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS) was employed to detect plasma rivaroxabd assays of rivaroxaban 10 mg, 15 mg, and 20 mg were about 210, 330, and 270 at peak concentrations, and 28, 44, and 58, respectively, at the trough concentrations. In this study, we confirm that target drug calibration of anti-Xa activity is a better quantitative detection method for oral direct FXa inhibitors than LMWH-calibrated anti-Xa activity in clinical practice, and expected peak-trough levels are recommended for the Asian population.

Based on observed clinical need, this investigation aimed to identify psychoeducational and emotional support needs of male HD caregivers and to explore the feasibility and utility of a carer support group. Six male caregivers completed quantitative measures assessing depression, anxiety, carer burden, and carer support needs. The men participated in two education and support group sessions, four weeks apart, which were developed with consideration of male support preferences. Qualitative themes arising in these sessions were documented. Questionnaire results showed overall low levels of psychological distress and carer burden. Despite this, the group sessions facilitated disclosure of significant emotional, practical, and relationship challenges arising from HD. Further, a range of psychoeducational and emotional support needs were identified on quantitative and qualitative assessments. Participants strongly endorsed the format of the group and the benefits of participation, highlighting in particular the importance of meeting other men who understood the experience of living with a spouse with HD. Systemic lupus erythematosus (SLE) can affect bone metabolism and homeostasis of serum electrolytes that are associated with abnormal levels of vitaminD. Mycophenolate mofetil (MMF) is a commonly used immunosuppressant with the active metabolite mycophenolic acid (MPA). The area under the plasma concentration-time curve (AUC) of MPA is often monitored during the treatment to assess the exposure levels. This study aims to explore the association between exposure levels of MPA and 25-hydroxyvitaminD [25(OH)D] levels in children with SLE. Repeated measured data of children with SLE who were treated with MMF and under therapeutic drug monitoring (TDM) were retrospectively collected from the electronic medical records. https://www.selleckchem.com/products/jzl184.html MPA exposure levels were reflected by the area under the concentration-time curve over 24h (AUC ). Univariate and multivariate linear regression models were employed to analyze factors associated with 25(OH)D levels. Hierarchical linear models were developed to analyze the intra- and inter-individual effects of AUC on the variance of 25(OH)D levels.
