Objectives: Real-world evidence (RWE) is valuable in supporting regulatory and health technology assessment (HTA) decisions; however, the actual contribution to approvals remains elusive. This study aimed to review RWE approaches and use in oncology medicine approvals in Europe and understand cohesion and discrepancy in the acceptance of the RWE by the European Medicines Agency (EMA) and European HTA bodies.

Methods: This scoping review involved a search of the EMA database, National Institute for Health and Care Excellence (NICE), Gemeinsamer Bundesausschuss (G-BA), and Haute Autorité de Santé (HAS) websites to identify final reports and appraisals for oncology medicines with references to RWE.

Platelet-rich plasma (PRP) is widely used in various medical and surgical specialties for its regenerative properties, including aesthetics (facial rejuvenation, hair restoration, and skin tightening) and orthopedics (treatment of tendinitis and osteoarthritis). However, the inconsistent literature on PRP's efficacy and safety leads to critical knowledge gaps. This systematic review evaluates quality control measures in PRP preparation and application and explores the regulatory environment governing its clinical use.

Introduction: Exosomes, diminutive extracellular vesicles, are integral to intercellular communication, harbouring potential for applications in regenerative medicine and aesthetic interventions. The field, however, grapples with the complexities of harmonising exosome characterisation protocols and safeguarding therapeutic integrity.

Methodology: In this scholarly overview, systematic adherence to the Cochrane Collaboration and Preferred Reporting Items for Overviews of Reviews guidelines was observed, scrutinising the congruence of exosome-related therapies with the Minimal Information for Studies of Extracellular Vesicles standards delineated by the International Society for Extracellular Vesicles, alongside criteria set forth by the International Society for Cell Therapy and the International Society for Stem Cell Research.

There is a compelling need to find drugs active against (). 4'-Phosphopantetheinyl transferase (PptT) is an essential enzyme in that has attracted interest as a potential drug target. We optimized a PptT assay, used it to screen 422,740 compounds, and identified raltitrexed, an antineoplastic antimetabolite, as the most potent PptT inhibitor yet reported.

The combination of bedaquiline, pretomanid, and linezolid (BPaL) has become a preferred regimen for treating multidrug- and extensively drug-resistant tuberculosis (TB). However, treatment-limiting toxicities of linezolid and reports of emerging bedaquiline and pretomanid resistance necessitate efforts to develop new short-course oral regimens. We recently found that the addition of GSK2556286 increases the bactericidal and sterilizing activity of BPa-containing regimens in a well-established BALB/c mouse model of tuberculosis.
