Abstract

Decitabine has shown clinical benefits in patients with intermediate (INT)-2 or high-risk myelodysplastic syndrome (MDS), determined according to the International Prognostic Scoring System (IPSS), but the benefits have not been well demonstrated in patients with lower-risk (IPSS low or INT-1) disease. Recently, it was proposed that the prognosis for patients with IPSS lower-risk disease is heterogeneous, with a substantial proportion of these patients having poor survival. This study included patients with IPSS lower-risk MDS from the DRAMA (An Observational Study for Dacogen Long-Term Treatment in Patients With Myelodysplastic Syndrome; NCT01400633) and DIVA (A Study for Dacogen Treatment in Patients With Myelodysplastic Syndrome; NCT01041846) studies, which were prospective observational studies on the efficacy and safety of decitabine treatment in patients with MDS. Using the Lower-Risk Prognostic Scoring System [LR-PSS], we classified IPSS lower-risk MDS. Patients in each LR-PSS category were divided according to overall response (OR) to decitabine treatment, and survival outcomes were compared. One hundred sixteen patients were enrolled: LR-PSS category 1 (n = 12; 10.3%), category 2 (n = 56; 48.3%), and category 3 (n = 48...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Cardiovascular Risk Prediction

Cardiovascular risk prediction models based on classical risk factors identified in epidemiological studies are useful in primary prevention of cardiovascular disease in individuals. Here is the latest research.
