Research review (peer-reviewed)abstract
- In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

Next-generation ARIA care pathways for rhinitis and asthma : a model for multimorbid chronic diseases
- 2019
-
In: Clinical and Translational Allergy. - : BMC. - 2045-7022. ; 9
-
Research review (peer-reviewed)abstract
- Background: In all societies, the burden and cost of allergic and chronic respiratory diseases are increasing rapidly. Most economies are struggling to deliver modern health care effectively. There is a need to support the transformation of the health care system into integrated care with organizational health literacy.Main body: As an example for chronic disease care, MASK (Mobile Airways Sentinel NetworK), a new project of the ARIA (Allergic Rhinitis and its Impact on Asthma) initiative, and POLLAR (Impact of Air POLLution on Asthma and Rhinitis, EIT Health), in collaboration with professional and patient organizations in the field of allergy and airway diseases, are proposing real-life ICPs centred around the patient with rhinitis, and using mHealth to monitor environmental exposure. Three aspects of care pathways are being developed: (i) Patient participation, health literacy and self-care through technology-assisted "patient activation", (ii) Implementation of care pathways by pharmacists and (iii) Next-generation guidelines assessing the recommendations of GRADE guidelines in rhinitis and asthma using real-world evidence (RWE) obtained through mobile technology. The EU and global political agendas are of great importance in supporting the digital transformation of health and care, and MASK has been recognized by DG Sante as a Good Practice in the field of digitally-enabled, integrated, person-centred care.Conclusion: In 20 years, ARIA has considerably evolved from the first multimorbidity guideline in respiratory diseases to the digital transformation of health and care with a strong political involvement.

ARIA digital anamorphosis : Digital transformation of health and care in airway diseases from research to practice
- 2021
-
In: Allergy. European Journal of Allergy and Clinical Immunology. - : John Wiley & Sons. - 0105-4538 .- 1398-9995. ; 76:1, s. 168-190
-
Research review (peer-reviewed)abstract
- Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed.

A Comparison of Visual Field Progression Criteria of 3 Major Glaucoma Trials in Early Manifest Glaucoma Trial Patients.

Journal article (peer-reviewed)abstract
- PURPOSE: Three major glaucoma trials, all using the same Humphrey visual field tests, specified different criteria to define visual field progression. This article compares the performance of these criteria with a reference standard of unanimous classifications by 3 independent glaucoma experts. DESIGN: Longitudinal, comparative study of diagnostic criteria. PARTICIPANTS AND CONTROLS: Two hundred forty-five patients with manifest glaucoma in the Early Manifest Glaucoma Trial (EMGT). METHODS: Visual field series of 1 eye of each of 245 EMGT patients were classified by 3 independent glaucoma specialists as definitely progressing, definitely nonprogressing, or neither. Field series that were classified in the first 2 categories by all 3 experts met the reference standards for the progressing and nonprogressing groups and were analyzed according to the progression criteria of the Advanced Glaucoma Intervention Study (AGIS), the Collaborative Initial Glaucoma Treatment Study (CIGTS), and the EMGT. Sensitivity, specificity, time to progression, and sustainability were calculated. MAIN OUTCOME MEASURES: Progression, nonprogression, sensitivity, specificity, time to progression, and sustainability. RESULTS: Seventy-seven field series were definitely progressing, and 95 series were definitely nonprogressing. Among progressing eyes, 45 (58%) of 77 were identified using AGIS criteria, 58 (75%) of 77 were identified with CIGTS criteria, and 74 (96%) of 77 were identified with EMGT criteria; all comparisons of sensitivities were significant, simultaneous (P<0.001), and pairwise (P<0.01). The specificity for EMGT criteria was 89%, lower (P<0.05) than that of AGIS (98%) and CIGTS (99%) criteria. Median time to progression was considerably shorter with EMGT criteria (33 months; 95% confidence interval [CI], 30-36 months) than with AGIS (66 months; 95% CI, 57-78 months) and CIGTS (55 months; 95% CI, 48-66 months) criteria. Sustainability increased with time after progression; it averaged 79%, 84%, and 81%, respectively, for AGIS, CIGTS, and EMGT criteria during the first year after the first progression and 95%, 100%, and 93% during the fourth year after progression. CONCLUSIONS: The EMGT criteria identified progression earlier and more often than AGIS and CIGTS criteria. Specificity was good for all criteria but was better with AGIS and CIGTS than with EMGT criteria. Sustainability was high for all 3 sets of criteria and best for CIGTS criteria and increased with time after progression.
