- Pharmacy interventions on COVID-19 in Europe: mapping current practices and a scoping reviewPublication . Costa, Suzete; Romão, Mariana; Mendes, Maria; Horta, Rute; Rodrigues, António Teixeira; Carneiro, António Vaz; Martins, Paula; Mallarini, Erika; Naci, Huseyin; Babar, Zaheer-Ud-DinBackground: The COVID-19 pandemic has put community pharmacists at the frontline of prevention, preparedness, response, and recovery efforts. Pharmacies had to reorganize and implement several different interventions and measures within a very short time frame. Objectives: 1) To map the current reported practice and trends and to review the literature on pharmacy-based interventions on COVID-19 provided in Europe; 2) To identify knowledge gaps and future avenues for pharmacy research, policy, and practice in response to public health emergencies. Methods: We used a mixed methods approach combining country mapping of current practices of pharmacy interventions on COVID-19 reported by pharmacy associations in Europe with a scoping review of published literature. Results: We mapped current practices on 31 pharmacy interventions on COVID-19 in 32 countries in Europe. Almost all preventive measures to reduce health risks have been provided in most countries. Other frequent interventions reflected preparedness for stockpiling, increased demand for services and products, and important patient care interventions exceeding dispensing role. Expanded powers granted to pharmacies and legislation passed in view of COVID-19 enabled services that improve access to medicines and relevant products, patient screening and referral including point-of-care antigen testing, support to vulnerable patients, and COVID-19 vaccination. We identified 9 studies conducted in pharmacies in 7 countries in Europe. Most studies are cross-sectional and/or descriptive. Pharmacy associations played an important supporting role by developing and updating guidance and emergency plans to assist community pharmacists. Conclusions: A wide array of pharmacy interventions on COVID-19 was implemented in several countries within a very short time frame. Research on pharmacy interventions on COVID-19 is still in its infancy but confirmed the wide array of interventions provided and expanded powers granted to pharmacies. These findings may provide a significant impact to improve pharmacy research, policy, and practice in response to future public health emergencies in Europe and globally.
- Sorting hidden patterns in nanoparticle performance for glioblastoma using machine learning algorithmsPublication . Basso, João; Mendes, Maria; Silva, Jessica; Cova, Tânia; Luque-Michel, Edurne; Jorge, Andreia F.; Grijalvo, Santiago; Gonçalves, Lídia; Eritja, Ramon; Blanco-Prieto, María J.; Almeida, António José; Pais, Alberto; Vitorino, CarlaCationic compounds have been described to readily penetrate cell membranes. Assigning positive charge to nanosystems, e.g. lipid nanoparticles, has been identified as a key feature to promote electrostatic binding and design ligand-based constructs for tumour targeting. However, their intrinsic high cytotoxicity has hampered their biomedical application. This paper seeks to establish which cationic compounds and properties are compelling for interface modulation, in order to improve the design of tumour targeted nanoparticles against glioblastoma. How can intrinsic features (e.g. nature, structure, conformation) shape efficacy outcomes? In the quest for safer alternative cationic compounds, we evaluate the effects of two novel glycerol-based lipids, GLY1 and GLY2, on the architecture and performance of nanostructured lipid carriers (NLCs). These two molecules, composed of two alkylated chains and a glycerol backbone, differ only in their polar head and proved to be efficient in reversing the zeta potential of the nanosystems to positive values. The use of unsupervised and supervised machine learning (ML) techniques unraveled their structural similarities: in spite of their common backbone, GLY1 exhibited a better performance in increasing zeta potential and cytotoxicity, while decreasing particle size. Furthermore, NLCs containing GLY1 showed a favorable hemocompatible profile, as well as an improved uptake by tumour cells. Summing-up, GLY1 circumvents the intrinsic cytotoxicity of a common surfactant, CTAB, is effective at increasing glioblastoma uptake, and exhibits encouraging anticancer activity. Moreover, the use of ML is strongly incited for formulation design and optimization.
