Blue Zones are regions of the world that have a higher number of individuals who live longer than the expected average. The current paper revisits principles previously identified to be common in Blue Zones and to be contributing to longevity ( move naturally, eat wisely, improve resilience to stress, get adequate sleep, keep strong family ties, stimulate strong community support, respect for the planet and having a purpose in life’), compares these to the 6 pillars of Lifestyle Medicine ( healthy eating, exercising, avoidance of smoking and other risky substances, stress management, restorative sleep, and forming and maintaining relationships) and reviews new studies investigating the association between behavioral factors and longevity. In addition to the role of behavior, the review also discusses the important role of genetics and emphasizes the importance of conducting further research to understand how behavioral and genetic factors may affect molecular pathways with consequent effects on wellbeing and longevity.

SUR2A is an ABC protein serving as a regulatory subunit of ATP-sensitive (KATP) channels. An increase in SUR2A levels is cardioprotective and it is a potential therapeutic strategy against ischaemic heart disease, heart failure and other diseases. However, whether overexpression of this protein has any adverse effects is yet to be fully understood. Objectives Here, we examined the heart rate and the heart rate diurnal variation in mice overexpressing SUR2A (SUR2A+) and their littermate controls (WT) using ECG telemetry that was continuously recorded for 14 days (days 8–23 post-radiotransmitter implantation). Methods Using SigmaPlot 14.0 and Microsoft Excel, Area Under the Curve (AUC) for each parameter was calculated and plotted in a graph. Results Both WT and SUR2A+ mice were more physically active during nights and there were no significant differences between two phenotypes. Physical activity was associated with increased heart rate in both phenotypes, but there were no differences in heart rate between phenotypes irrespective of physical activity or time of the day. A diurnal heart rate variation was preserved in the SUR2A+ mice. As area under the curve (AUC) analysis has the potential to reveal differences that are invisible with other statistical methods, we compared AUC of heart rate in SUR2A+ and WT mice. This analysis did not yield anything different from traditional analysis. Conclusions We conclude that increased SUR2A levels are not associated with changes in physical activity, heart rate and/or circadian rhythm influence on the heart rate. This lack of adverse effects supports a notion that manipulation with SUR2A levels is a promising cardioprotective strategy.

Background: Adult atopic dermatitis (AD) is defined as a continuum of childhood AD or the development of the disease in adulthood, accounting for 7.7–59.7% of adult AD cases varying in severity and manifestations. The symptomatology of moderate-to-severe adult AD may significantly impact the overall health and quality of life of the patient. The “classic” topical treatments used in mild-to-moderate cases, such as emollients and topical corticosteroids, are usually not adequate to control the symptoms of most of the patients with moderate-to-severe disease. For many years these patients were managed with systemic corticosteroids and immunomodulators, leading to substantial side effects with questionable efficacy. The introduction of dupilumab, the first biologic agent approved by the Food and Drug Administration for use in adult moderate-to-severe AD, has commenced a new era in the management of AD. This narrative literature review addresses the question of how patients with moderate-to-severe AD may achieve a recession or improvement in the overall progression of the disease with the use of dupilumab in both an efficient and safe way. Material and Methods: A search in the PubMed, Embase, and Cochrane databases was conducted using the following combination of MeSH terms: “dupilumab” AND “atopic” (“dermatitis” OR “eczema”). The searches were limited to RCTs written in the English language published before January 25, 2021. The literature used included phase II and III RCTs examining the efficacy and/or safety of dupilumab compared to placebo or other treatments in adults with moderate-to-severe AD. Moderate-to-severe AD was defined by an IGA score of 3 (moderate) or 4 (severe) and EASI 16 or higher at screening and baseline. Additionally, we searched the website clinicaltrials.gov for any unpublished or ongoing RCTs. The search was done independently by two authors in all databases and followed by the exclusion of duplicates. Results: Upon reviewing all randomized controlled trials, dupilumab was found to be an effective and safe option for managing adult moderate-to-severe AD with long-term therapeutic effects. Conclusion: The best results for maintaining long-term disease recession were achieved with the combination of dupilumab and topical corticosteroids.
