- The aim of this study was to assess any predictive factors for repeated attempted suicide and completed suicide in a 1-year follow-up on a sample of elderly European suicide attempters (60 years and over). From 1990 to 1993, 63 subjects completed the first interview and were recontacted after 1 year. At follow-up, eight subjects (12.7%) had taken their lives and seven (11.1%) had repeated at least one suicide attempt. On comparison of repeaters and non-repeaters, differences emerged in terms of death of the father in childhood and for mean Suicidal Intent Score. At the end of follow-up period, repeaters reported a more frequent desire to repeat suicidal behaviour and judged their mental health and social assistance received to be worse. Suicides and non-repeaters differed especially in relation to death of father during childhood and number of contacts with General Practitioner. Interpretation of the results must take into account the smallness of the test sample, the difficulties in obtaining complete data for the follow-up interview, the lack of a control group and a diagnosis formulated in a hospital consultation setting. The study confirms, however, the high risk of repetition of suicidal behaviour in the elderly. In old age suicidal ideation is often sustained over long periods of time and requests for help are addressed to relatives and GPs. An interesting finding is the more frequent death of the father during childhood among repeaters.

- Rosiglitazone, a thiazolidinedione, enhances peripheral insulin sensitivity in patients with type 2 diabetes. Because the synergic action of insulin and exercise has been shown to be decreased in insulin resistance, the aim of this study was to compare the effects of rosiglitazone and metformin on muscle insulin responsiveness at rest and during exercise in patients with type 2 diabetes. Therefore, 45 patients with newly diagnosed or diet-treated type 2 diabetes were randomized for treatment with rosiglitazone (4 mg b.i.d.), metformin (1 g b.i.d.), or placebo in a 26-week double-blind trial. Skeletal muscle glucose uptake was measured using fluorine-18-labeled fluoro-deoxy-glucose and positron emission tomography (PET) during euglycemic-hyperinsulinemic clamp and one-legged exercise before and after the treatment period. Rosiglitazone (P < 0.05) and metformin (P < 0.0001) treatment lowered the mean glycosylated hemoglobin. The skeletal muscle glucose uptake was increased by 38% (P < 0.01) and whole-body glucose uptake by 44% in the rosiglitazone group. Furthermore, the exercise-induced increment during insulin stimulation was enhanced by 99% (P < 0.0001). No changes were observed in skeletal muscle or whole-body insulin sensitivity in the metformin group. In conclusion, rosiglitazone but not metformin 1) improves insulin responsiveness in resting skeletal muscle and 2) doubles the insulin-stimulated glucose uptake rate during physical exercise in patients with type 2 diabetes. Our results suggest that rosiglitazone improves synergic action of insulin and exercise.
