Lifestyle Medicine During (and After) the COVID-19 Pandemic.

The COVID-19 pandemic has made it challenging for individuals and families to maintain a healthy lifestyle, quality of life, and well-being. Preliminary evidence have suggested that higher odds of both mortality and severity of the COVID-19 are closely associated to unhealthy lifestyle behaviors. Thus, in an effort to contribute to this challenging global situation, we joined a group of lifestyle medicine researchers and/or practitioners to provide scientifically sound information, recommendations, resources, and suggestions related to the main pillars of lifestyle medicine (healthy eating, physical activity, sleep, tobacco/alcohol, stress management, relationships, and planetary health) that may help health practitioners to support clients and patients maintain a healthy lifestyle during (and after) the COVID-19 crisis.

Collagen and elastic system in the remodelling process of major types of idiopathic interstitial pneumonias (IIP).

Aims: Structural remodelling in acute and chronic idiopathic interstitial pneumonia (IIP) has been extensively investigated, but little attention has been directed to the elastic tissue in these situations. The aim of this study was to determine whether elastic deposition accompanies collagen deposition in the four major histological patterns of IIP: diffuse alveolar damage (DAD), organizing pneumonia (OP), non-specific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP).

Methods And Results: We measured, by image analysis, the content of fibres of the collagenous and elastic systems of the alveolar septum in histological slides of open lung biopsies, using the picrosirius-polarization method and Weigert's resorcin-fuchsin stain, respectively.
