Many drugs are chiral with their chirality determining their biological interactions, safety, and efficacy. Since the 1980s, there has been a regulatory preference to bring single enantiomer to market. This perspective discusses trends related to chirality that have developed in the past decade (2013-2022) of new drug approvals. The EMA has not approved a racemate since 2016, while the average for the FDA is one per year from 2013 to 2022. These 10 include drugs which have been previously marketed elsewhere for several decades, analogues of pre-existing drugs, or drugs where the undefined stereocenter does not play a role in therapeutic activity. Two chiral switches were identified which were both combined with drug repurposing. This combination strategy has the potential to produce therapeutically valuable drugs in a faster time frame. Two class III atropisomers displaying axial chirality were approved between 2013 and 2022, one as a racemate and one as a single enantiomer.

Background Carotid artery stenting is a well-established alternative treatment to carotid endarterectomy for carotid artery stenosis for preventing stroke. This study assessed the procedural and clinical outcomes in patients undergoing carotid artery stenting in a tertiary care center in India. Methods A total of 39 patients underwent carotid artery stenting from January 2022 to December 2023, with different embolic protection devices and carotid stents.

Introduction: Tranexamic acid (TXA) is an antifibrinolytic drug commonly used in total knee arthroplasty (TKA). Intravenous (IV) and topical TXA therapy have been extensively studied and shown to reduce blood loss, length of hospital stay, and blood transfusion rates following TKA. Despite the extensive literature regarding IV and topical TXA in orthopedics, there is a current dearth of studies analyzing oral usage.

Background: Letermovir is approved for primary prophylaxis of cytomegalovirus (CMV) in high-risk kidney transplant recipients. However, many experts suggest the drug be reserved as a second-line agent when valganciclovir is not tolerated or fails.
Objective: The purpose of this study was to describe the feasibility of a de novo letermovir prophylactic approach for CMV high-risk and seropositive abdominal solid organ transplant patients.

Objectives: To explore the role of newly emerging autoantibodies (AAbs) - peptidyl-arginine deiminase 4 (aPAD4), carbamylated proteins (aCarP), and anti-RA33 (aRA33) - alongside the traditionally assessed rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA), in predicting the response to abatacept (ABT) and its retention rate in rheumatoid arthritis (RA) patients.
Methods: Data from 121 consecutive ABT-treated RA patients were recorded. The RF and ACPA status were retrospectively assessed by reviewing the patients' clinical records.
