[Criteria for the authorization of training in medical specialist competence in internal medicine and rheumatology-A position paper of the German Society for Rheumatology and Clinical Immunology].

The model advanced training regulations define the content of advanced training to achieve the qualification of medical specialist in internal medicine and rheumatology. There are currently no criteria for issuing the authorization in advanced training. This position paper describes the criteria proposed by the German Society for Rheumatology and Clinical Immunology (DGRh), which should be the foundation for the issuance of authorization for advanced training in the field of internal medicine and rheumatology and for the assessment of the duration.

Artificial intelligence in rheumatology: status quo and quo vadis-results of a national survey among German rheumatologists.

Background: The development and potential of artificial intelligence (AI) is remarkable. Its application in all medical disciplines, including rheumatology, is attracting attention. To what extent AI is already used in clinical routine in rheumatology is unknown.

Clinical features and rehabilitation outcome after surgical treatment of spinal meningioma.

Study Design: Retrospective analysis of clinical routine data.

Objectives: Spinal meningioma is a common type of benign spinal tumor. Surgical removal is the standard therapeutic approach.

ZBTB18 regulates cytokine expression and affects microglia/macrophage recruitment and commitment in glioblastoma.

Glioma associated macrophages/microglia (GAMs) play an important role in glioblastoma (GBM) progression, due to their massive recruitment to the tumor site and polarization to a tumor promoting phenotype. GAMs secrete a variety of cytokines, which facilitate tumor cell growth and invasion, and prevent other immune cells from mounting an immune response against the tumor. Here, we demonstrate that zinc finger and BTB containing domain 18 (ZBTB18), a transcriptional repressor with tumor suppressive function in glioblastoma, impairs the production of key cytokines, which function as chemoattractant for GAMs.

Climate factors and food availability shape the altitudinal migration of birds in the Xiling Snow Mountains, China.

Many bird species in montane regions display altitudinal migration, but so far, the underlying ecological driving mechanisms are not clear. We studied the altitudinal migration behavior patterns and factors influencing altitudinal migration in the Xiling Snow Mountains, which are part of the Hengduan mountain range in southwest China. We recorded the local bird diversity, the seasonal change of: the average temperature (AT), the average humidity (AH), the average invertebrate biomass (AIB), and the amount of plant food sources (PFS) at two study sites (∼1300 and ∼2100 m a.
