Objective: To detect levofloxacin (LFX) and moxifloxacin (MFX) resistance among rifampicin-resistant tuberculosis (RR-TB) isolates, and predict the resistance level based on specific mutations in gyrA and gyrB genes. Methods: A total of 686 RR-TB isolates were collected from Chinese Drug Resistance Surveillance Program from 2013 to 2020. The minimum inhibitory concentrations (MICs) of 12 anti-TB drugs were acquired using the broth microdilution method, followed by whole genome sequencing (WGS) analysis. Results: Among the 686 RR isolates, the most prevalent resistance was to isoniazid (80.5 %)

Abstract Introduction Interleukin-1 receptor-associated kinase 4 (IRAK4) is expressed in various immune cells and regulates proinflammatory cytokine production. Its inhibition represents a novel, promising therapeutic option in the treatment of atopic dermatitis (AD). Zabedosertib (BAY1834845) is a potent, selective IRAK4 inhibitor that suppresses markers of local and systemic immune responses. This study aimed to evaluate the efficacy and safety of zabedosertib in adults with moderate-to-severe AD.

Abstract Background Dipeptidyl peptidase 4 (DPP4) inhibitors improve glycemic control by promoting GLP1-mediated glucose-dependent insulin secretion and suppression of glucagon. Sitagliptin and vildagliptin have been shown to improve insulin sensitivity in patients with type 2 diabetes mellitus (T2DM). However, these patients had uncontrolled blood glucose at inclusion; therefore, the improvement in insulin sensitivity observed in these studies could be attributed to the drug per se and/or reduction in glucotoxicity. This study examines the effect of linagliptin on insulin sensitivity and β-ce
