Thousands of self-help organisations (SHOs) exist in Australia but little is known about how they relate to the mainstream health care system. This qualitative study, based in south-east Queensland, aimed to identify examples of collaboration between general practitioners (GPs) and SHOs in order to examine the attributes of successful partnerships. Representatives of six SHOs, identified by key informants as having good collaborative links with GPs, and seven GPs with whom they collaborated, completed semi-structured interviews. The interviews focused on evidence of collaboration and perceptions of benefits and barriers experienced. Maximum variation sampling enabled a cross-section of SHOs in terms of size, funding, and health issue. Although GPs readily identified SHO benefits, they referred patients to them only rarely. SHO credibility, evidence of tangible benefits for patients, ease of contacting the SHO, and correspondence between the SHO?s focus and the GP?s personal and professional interests appear to contribute to the success of partnerships. We conclude that mutually beneficial partnerships between GPs and SHOs exist but are under-utilised. A more coordinated effort is needed to strengthen links between the two sectors.

BACKGROUND: Patients with advanced cancer suffer from cachexia, which is characterised by a marked weight loss, and is invariably associated with the presence of tumoral and humoral factors which are mainly responsible for the depletion of fat stores and muscular tissue. METHODS: In this work, we used cytotoxicity and enzymatic assays and morphological analysis to examine the effects of a proteolysis-inducing factor (PIF)-like molecule purified from ascitic fluid of Walker tumour-bearing rats (WF), which has been suggested to be responsible for muscle atrophy, on cultured C2C12 muscle cells. RESULTS: WF decreased the viability of C2C12 myotubes, especially at concentrations of 20-25 mug.mL-1. There was an increase in the content of the pro-oxidant malondialdehyde, and a decrease in antioxidant enzyme activity. Myotubes protein synthesis decreased and protein degradation increased together with an enhanced in the chymotrypsin-like enzyme activity, a measure of functional proteasome activity, after treatment with WF. Morphological alterations such as cell retraction and the presence of numerous cells in suspension were observed, particularly at high WF concentrations. CONCLUSION: These results indicate that WF has similar effects to those of proteolysis-inducing factor, but is less potent than the latter. Further studies are required to determine the precise role of WF in this experimental model. © 2008 Yano et al; licensee BioMed Central Ltd.
