Throughout history, humans have relied on wood for constructions, tool production or as an energy source. How and to what extent these human activities have impacted plant abundance and composition over a long-term perspective is, however, not well known. To address this knowledge gap, we combined 44,239 precisely dated tree-ring samples from economically and ecologically important tree species (spruce, fir, pine, oak) from historical buildings, and pollen-based plant cover estimates using the REVEALS model from 169 records for a total of 34 1° × 1° grid cells for Central Europe.

Objective: To evaluate whether nasal colonization with Staphylococcus aureus (SA) before radiation therapy is associated with ARD severity in patients with breast or head and neck cancer.
Background: There is limited research on the association between vitiligo support group membership and patient quality of life (QoL).
Objectives: To explore the association between support groups and QoL in those with vitiligo by evaluating and comparing the QoL of vitiligo support group members and non-support group members.
Methods: Support group members (n=135) and non-support group members (n=129) were recruited from the Global Vitiligo Foundation (GVF), and three academic medical centers respectively.
