OBJECTIVE: To describe the utility and acceptability to general practitioners and palliative care staff of case conferences in palliative care. METHOD: Research focussed on case conferences conducted between GPs and staff of three specialist palliative care units (in an inner urban, outer metropolitan and regional setting), at the time of referral of patients to the service. Telephone interviews were conducted with all GPs who participated in a case conference, and focus groups were conducted with palliative care staff. RESULTS: For most GPs, case conferences by teleconference were a time effective and immediate means of information transfer. The best instances for a conference were at time of patient referral, time of discharge to the community, or where the case was complex. General practitioners appreciated access to multiple professionals simultaneously. Workload pressures were a drawback of participation for both GPs and specialists. Palliative care team members thought case conferences gave GPs an appreciation of a team approach, and reduced professional isolation. The usefulness of the case conferences depended on the willingness of the GP to participate. General practitioners would participate again provided they did not have to organise the case conference. Specialist staff were concerned by the financial cost of organising case conferences. DISCUSSION: Case conferences provide useful information exchange between GPs and specialist staff, and are acceptable to both parties. Much depends on the individual GPs attitude toward participation, as well as the timing of the conferences in the course of the patient's illness. Organisation needs to be a task of the specialist units, who would need administrative support to organise them. (author abstract)
Highly demanding resistive vibration exercise program is tolerated during 56 days of strict bed-rest

Several studies have tried to find countermeasures against musculoskeletal de-conditioning during bed-rest, but none of them yielded decisive results. We hypothesised that resistive vibration exercise (RVE) might be a suitable training modality. We have therefore carried out a bed-rest study to evaluate its feasibility and efficacy during 56 days of bed-rest. Twenty healthy male volunteers aged 24 to 43 years were recruited and, after medical check-ups, randomised to a non-exercising control (Ctrl) group or a group that performed RVE 11 times per week. Strict bed-rest was controlled by video surveillance. The diet was controlled. RVE was performed in supine position, with a static force component of about twice the body weight and a smaller dynamic force component. RVE comprised four different units (squats, heel raises, toe raises, kicks), each of which lasted 60 - 100 seconds. Pre and post exercise levels of lactate were measured once weekly. Body weight was measured daily on a bed scale. Pain questionnaires were obtained in regular intervals during and after the bed-rest. Vibration frequency was set to 19 Hz at the beginning and progressed to 25.9 Hz (SD 1.9) at the end of the study, suggesting that the dynamic force component increased by 90%. The maximum sustainable exercise time for squat exercise increased from 86 s (SD 21) on day 11 of the BR to 176 s (SD 73) on day 53 (p = 0.006). On the same days, post-exercise lactate levels increased from 6.9 mmol/l (SD2.3) to 9.2 mmol/l (SD 3.5, p = 0.01). On average, body weight was unchanged in both groups during bed-rest, but single individuals in both groups depicted significant weight changes ranging from -10% to + d10% (p < 0.001). Lower limb pain was more frequent during bed-rest in the RVE subjects than in Ctrl (p = 0.035). During early recovery, subjects of both groups suffered from muscle pain to a comparable extent, but foot pain was more common in Ctrl than in RVE (p = 0.013 for plantar pain, p = 0.074 for dorsal foot pain). Our results indicate that RVE is feasible twice daily during bed-rest in young healthy males, provided that one afternoon and one entire day per week are free. Exercise progression, mainly by progression of vibration frequency, yielded increases in maximum sustainable exercise time and blood lactate. In conclusion, RVE as performed in this study, appears to be safe.

The present study examines the effect of the goodness of view on the minimal exposure time required to recognize depth-rotated objects. In a previous study, Verfaillie and Boutsen (1995) derived scales of goodness of view, using a new corpus of images of depth-rotated objects. In the present experiment, a subset of this corpus (five views of 56 objects) is used to determine the recognition exposure time for each view, by increasing exposure time across successive presentations until the object is recognized. The results indicate that, for two thirds of the objects, good views are recognized more frequently and have lower recognition exposure times than bad views.
