[Social Support or Social Contagion? How Patients with Eating Disorders in Inpatient Settings Affect Each Other].

Objective: Living with others can provide social support for people with eating disorders. However, peer contagion is possible if competition arises and patients try to outdo each other in their symptomatic behavior.

Method: In 2 qualitative studies, a total of 19 female patients were interviewed about their experiences in an inpatient setting.

Chondrocyte Culture Parameters for Matrix-Assisted Autologous Chondrocyte Implantation Affect Catabolism and Inflammation in a Rabbit Model.

Cartilage defects represent an increasing pathology among active individuals that affects the ability to contribute to sports and daily life. Cell therapy, such as autologous chondrocyte implantation (ACI), is a widespread option to treat larger cartilage defects still lacking standardization of in vitro cell culture parameters. We hypothesize that mRNA expression of cytokines and proteases before and after ACI is influenced by in vitro parameters: cell-passage, cell-density and membrane-holding time.

The dependence of autologous chondrocyte transplantation on varying cellular passage, yield and culture duration.

Matrix-assisted chondrocyte transplantation (m-ACI) still lacks any standardization in its execution in terms of cell passage (P), cell yield (C) and in vitro membrane-holding time (T). It was the goal of this study to analyze the effect of shifting cell culture parameters (P, C, T) on the in vitro as well as in vivo effort of a regulated animal m-ACI. Autologous rabbit knee articular chondrocytes were seeded within bilayer collagen I/III 3-D matrices in variation of P, C and T.
