Impaired platelet aggregation and rebalanced hemostasis in patients with chronic hepatitis C virus infection

Increased risk of both cardiovascular disease (CVD) and bleeding has been found in patients with chronic hepatitis C (CHC) infection, and a re-balanced hemostasis has been proposed. The aim of this study was to investigate functional whole blood coagulation and platelet function in CHC infection. The prospective study included 82 patients with CHC infection (39 with advanced liver fibrosis and 43 with no or mild liver fibrosis) and 39 healthy controls. A total of 33 patients were treated for CHC infection and achieved sustained virological response (SVR). Baseline and post-treatment blood samples were collected. Hemostasis was assessed by both standard coagulation tests and functional whole blood hemostatic assays (thromboelastograhy (TEG), and platelet aggregation (Multiplate). Patients with CHC and advanced fibrosis had impaired platelet aggregation both compared to patients with no or mild fibrosis and to healthy controls. Patients with CHC and advanced fibrosis also had lower antithrombin, platelet count, and coagulation factors II-VII-X compared to healthy controls. In contrast, TEG did not differ between groups. In treated patients achieving SVR, post-treatment platelet count was higher than pre-treatment counts (p = 0.033) and ADPtest, ASPItest, and RISTOhightest all increased post treatment (all p < 0.05). All Multiplate tests values, however, remained below those in the healthy controls. CHC-infected patients displayed evidence of rebalanced hemostasis with only partly hemostatic normalization in patients achieving SVR. The implications of rebalanced hemostasis and especially the impact on risk of CVD and bleeding warrants further studies

Periosteal pressure sensitivity (PPS) on sternum may be a measure of autonomic nervous system dysfunction (ANSD). We tested if a non-pharmacological PPS-feedback-guided treatment program based on non-noxious sensory nerve stimulation, known to reduce PPS, changed empowerment, treatment satisfaction, and quality of life in people with T2D, compared to usual treatment.Patients and Methods: Analysis of secondary endpoints in a single center, two-armed, parallel-group, observer-blinded, randomized controlled trial of individuals with T2D. Participants were randomized to non-pharmacological intervention as an add-on to treatment as usual. Endpoints were evaluated by five validated questionnaires: Diabetes specific Empowerment (DES-SF), Diabetes Treatment Satisfaction (DTSQ), quality of life (QOL) (WHO-5), clinical stress signs (CSS), and self-reported health (SF-36). Sample size calculation was based on the primary endpoint HbA1c.Results: We included 144 participants, 71 allocated to active intervention and 73 to the control group. Active intervention compared to control revealed improved diabetes-specific empowerment (p = 0.004), DTSQ (p = 0.001), and SF-36 self-reported health (p=0.003) and tended to improve quality of life (WHO-5) (p = 0.056). The findings were clinically relevant with a Cohen’s effect size of 0.5 to 0.7.Conclusion: This non-pharmacological intervention, aiming to reduce PPS, and thus ANSD, improved diabetes-specific empowerment, treatment satisfaction, and self-reported health when compared to usual treatment. The proposed intervention may be a supplement to conventional treatment for T2D.Keywords: type 2 diabetes, empowerment, autonomic nervous system dysfunction, periosteal pressure sensitivit

2012 ACCF/AHA/ACP/AATS/PCNA/SCAI/STS guideline for the diagnosis and management of patients with stable ischemic heart disease

The recommendations listed in this document are, whenever possible, evidence based. An extensive evidence review was conducted as the document was compiled through December 2008. Repeated literature searches were performed by the guideline development staff and writing committee members as new issues were considered. New clinical trials published in peer-reviewed journals and articles through December 2011 were also reviewed and incorporated when relevant. Furthermore, because of the extended development time period for this guideline, peer review comments indicated that the sections focused on imaging technologies required additional updating, which occurred during 2011. Therefore, the evidence review for the imaging sections includes published literature through December 2011
