    Resilience and Adaptability in Paracetamol Supply Chains: A Systems Perspective on COVID-19 Challenges and Responses in Ethiopia

    Full text link
    Background: The COVID-19 pandemic exposed vulnerabilities in global supply chains, including those for essential medicines like paracetamol. This study aimed to assess the resilience and adaptability of Ethiopia’s paracetamol supply chain during the pandemic. Methods: A mixed-methods approach was employed, combining semi-structured interviews with key stakeholders and analysis of secondary data on paracetamol availability and supply chain disruptions. The study employed systems thinking and supply chain resilience frameworks, utilizing causal loop diagrams to visualize system dynamics. Results: Eighteen stakeholders, representing seven pharmaceutical manufacturers, five import companies, and five wholesalers, participated in the study. These participants had between three and fourteen years of experience in their respective roles. The study revealed complex interactions within the paracetamol supply chain, highlighting both challenges and adaptive responses. While 500 mg paracetamol tablets were readily available, shortages of other formulations were observed due to a range of factors, including limited product diversification, political instability, inflation, and reduced production efficiency. Conclusions: The resilience and adaptability of stakeholders, particularly manufacturers and importers, were crucial in maintaining the supply of 500 mg paracetamol tablets. Key strategies included regional sourcing, increased production, and improved partnerships. Understanding the interconnectedness of factors within the supply chain is essential for developing effective strategies to enhance its resilience and ensure sustained access to paracetamol in the future.Resilience and Adaptability in Paracetamol Supply Chains: A Systems Perspective on COVID-19 Challenges and Responses in EthiopiapublishedVersio

    Hazard characterization of the mycotoxins enniatins and beauvericin to identify data gaps and improve risk assessment for human health

    Enniatins (ENNs) and beauvericin (BEA) are cyclic hexadepsipeptide fungal metabolites which have demonstrated antibiotic, antimycotic, and insecticidal activities. The substantial toxic potentials of these mycotoxins are associated with their ionophoric molecular properties and relatively high lipophilicities. ENNs occur extensively in grain and grain-derived products and are considered a food safety issue by the European Food Safety Authority (EFSA). The tolerable daily intake and maximum levels for ENNs in humans and animals remain unestablished due to key toxicological and toxicokinetic data gaps, preventing full risk assessment. Aiming to find critical data gaps impeding hazard characterization and risk evaluation, this review presents a comprehensive summary of the existing information from in vitro and in vivo studies on toxicokinetic characteristics and cytotoxic, genotoxic, immunotoxic, endocrine, reproductive and developmental effects of the most prevalent ENN analogues (ENN A, A1, B, B1) and BEA. The missing information identified showed that additional studies on ENNs and BEA have to be performed before sufficient data for an in-depth hazard characterisation of these mycotoxins become available.Hazard characterization of the mycotoxins enniatins and beauvericin to identify data gaps and improve risk assessment for human healthpublishedVersio
