To investigate the prevalence of symptomatic obstructive sleep apnoea in unselected patients with Type 2 diabetes referred to a tertiary diabetes clinic.

Non-myeloablative conditioning hematopoietic cell transplantation (NMC-HCT) has improved the treatment of chronic lymphocytic leukemia (CLL) and follicular lymphoma (FL). In a cohort of 85 patients (45 with CLL and 40 with FL), we observed 5-yr overall survival (OS) and progression-free survival (PFS) of 53% and 38% in the CLL group and 81% and 76% in the FL group. In the both the CLL group and the FL group, a strong trend toward better OS and PFS was observed among patients in complete remission (CR) at HCT. Within the FL group, sixteen patients had at one or more time points in their disease history had transformed FL. In contrast to the poor survival found in patients with transformed FL in previous studies, the 5-yr OS was almost identical in patients with transformed and non-transformed FL, 83% and 78%, respectively. In conclusion, our study supports that NMC-HCT is a safe and efficacious treatment that can provide long-term survival in elderly, heavily pretreated patients with FL and CLL. Especially patients with FL, and also transformed FL, seemed to have a great benefit of NMC-HCT, and CR at the time of HCT was an important prognostic factor.

Physical inactivity is a risk factor for insulin resistance. We examined the effect of 9 days of bed rest on basal and insulin-stimulated expression of genes potentially involved in insulin action by applying hypothesis-generating microarray in parallel with candidate gene real-time PCR approaches in 20 healthy young men. Furthermore, we investigated whether bed rest affected DNA methylation in the promoter region of the peroxisome proliferator-activated receptor-γ coactivator-1α ( PPARGC1A) gene. Subjects were reexamined after 4 wk of retraining. We found that bed rest induced insulin resistance and altered the expression of more than 4,500 genes. These changes were only partly normalized after 4 wk of retraining. Pathway analyses revealed significant downregulation of 34 pathways, predominantly those of genes associated with mitochondrial function, including PPARGC1A. Despite induction of insulin resistance, bed rest resulted in a paradoxically increased response to acute insulin stimulation in the general expression of genes, particularly those involved in inflammation and endoplasmatic reticulum (ER) stress. Furthermore, bed rest changed gene expressions of several insulin resistance and diabetes candidate genes. We also observed a trend toward increased PPARGC1A DNA methylation after bed rest. We conclude that impaired expression of PPARGC1A and other genes involved in mitochondrial function as well as a paradoxically increased response to insulin of genes involved in inflammation and ER stress may contribute to the development of insulin resistance induced by bed rest. Lack of complete normalization of changes after 4 wk of retraining underscores the importance of maintaining a minimum of daily physical activity.

Exercise testing early post AMI was evaluated as a predictor of reinfarction in patients treated with thrombolytics. AMI patients exercise-tested prior to discharge were included in the study (n = 178). The patients were followed for 2.9 +/- 0.9 years (mean +/- 1 SD) for the development of new cardiac events defined as cardiac death or reinfarction. Cox regression analysis of clinical and exercise test variables showed that there was significant predictive value of treating heart failure with drugs from two or more therapeutic groups (P < 0.001; hazard ratio 9.4 (3.1-28.2) (estimate and 95% confidence interval)), such as those with a previous history of myocardial infarction (P = 0.001; hazard ratio 4.0 (1.7-9.6)) and of significant ST depression (P = 0.029; hazard ratio 2.5 (1.1-5.7)). Significant ST depression could be substituted by the delta ST/delta HR index (P = 0.042; hazard ratio 2.8 (1.2-6.8)). The exercise test had independent but limited prognostic value in AMI patients treated with thrombolytics. The delta ST/delta HR index did not improve the predictive value of the exercise test.
