The internet enables access to information and the purchasing of medical products of various quality and legality. Research and regulatory attention have focused on the trafficking of illicit substances, potential physical harms of pharmaceuticals, and possibilities like financial fraud. However, there is far less attention paid to antibiotics and other antimicrobials used to treat infections. With online pharmacies affording greater access, caution around antibiotic use is needed due to the increasing health risks of antimicrobial resistance (AMR). The COVID-19 pandemic has helped to normalise digital healthcare and contactless prescribing, amplifying the need for caution. Little is known of how antibiotics are consumed via digital pharmacy and implications for AMR prevention. To expand insight for AMR prevention policy in Australia and internationally, we use digital ethnographic methods to explore how digital pharmacies function in the context of health advice and policy related to AMR, commonly described as antimicrobial stewardship. We find that digital pharmacy marketplaces constitute 'pastiche medicine'. They curate access to pharmaceutical and information products that emulate biomedical authority combined with emphasis on the 'self-assembly' of healthcare. Pastiche medicine empowers the consumer but borrows biomedical expertise about antibiotics, untethering these goods from critical medicine information, and from AMR prevention strategies. We reflect on the implications of pastiche medicine for AMR policy, what the antibiotics case contributes to wider critical scholarship on digital pharmacy, and how medical humanities research might consider researching online consumption in future.

A thorough polyphasic taxonomic study, integrating genome-based taxonomic approaches, was carried out to characterize the RB5 strain isolated from root nodules of growing on the coastal dunes of Bousfer Beach (Oran, Algeria). The 16S rRNA gene sequence analysis revealed that strain RB5 had the highest similarity to LMG27940 (98.94%) and IzPS32d (98.

Periodontitis is a chronic periodontal inflammatory disease caused by periodontal pathogens commonly seen in adults. Eupalinolide B (EB) is a sesquiterpenoid natural product extracted from Eupatorium lindleyanum and has been reported as a potential drug for cancers and immune disorders. Here, we explored the ameliorative effects and underlying molecular mechanism of EB on periodontitis for the first time.

A compilation of factors over the past decade-including the availability of increasingly large and rich healthcare datasets, advanced technologies to extract unstructured information from health records and digital sources, advancement of principled study design and analytic methods to emulate clinical trials, and frameworks to support transparent study conduct-has ushered in a new era of real-world evidence (RWE). This review article describes the evolution of the RWE era, including pharmacoepidemiologic methods designed to support causal inferences regarding treatment effects, the role of regulators and other health authorities in establishing distributed real-world data networks enabling analytics at scale, and the many global guidance documents on principled methods of producing RWE. This article also highlights the growing opportunity for RWE to support decision making by regulators, health technology assessment groups, clinicians, patients, and other stakeholders and provides examples of influential RWE studies.

Specific tumor-targeted gene delivery remains an unsolved therapeutic issue due to aberrant vascularization in tumor microenvironment (TME). Some bacteria exhibit spontaneous chemotaxis toward the anaerobic and immune-suppressive TME, which makes them ideal natural vehicles for cancer gene therapy. Here, we conjugated ZIF-8 metal-organic frameworks encapsulating eukaryotic murine interleukin 2 () expression plasmid onto the surface of VNP20009, an attenuated strain with well-documented anti-cancer activity, and constructed a TME-targeted delivery system named /ZIF-8@.

Background: Digital health interventions have emerged as promising tools to promote health behavior change and improve health outcomes. However, a comprehensive synthesis of strategies contributing to these interventions is lacking.
Objective: This study aims to (1) identify and categorize the strategies used in digital health interventions over the past 25 years; (2) explore the differences and changes in these strategies across time periods, countries, populations, delivery methods, and senders; and (3) serve as a valuable reference for future researchers and practitioners to improve the effectiveness of digital health interventions.
