RIC-HSCT for MF/SS
No full textAdvanced-stage mycosis fungoides and Sezary syndrome (MF/SS) have a poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT), particularly using a reduced-intensity conditioning (RIC) regimen, is a promising treatment for advanced-stage MF/SS. We performed RIC-HSCT in nine patients with advanced MF/SS. With a median follow-up period of 954days after HSCT, the estimated 3-year overall survival was 85.7% (95% confidence interval, 33.4-97.9%) with no non-relapse mortality. Five patients relapsed after RIC-HSCT; however, in four patients whose relapse was detected only from the skin, persistent complete response was achieved in one patient, and the disease was manageable in other three patients by the tapering of immunosuppressants and donor lymphocyte infusion, suggesting that graft-versus-lymphoma effect and "down-staging" effect from advanced stage to early stage by HSCT improve the prognosis of advanced-stage MF/SS. These results suggest that RIC-HSCT is an effective treatment for advanced MF/SS

Cigarette Smoking and Hypertension
No full textCigarette smoking is a powerful cardiovascular risk factor and smoking cessation is the single most effective lifestyle measure for the prevention of a large number of cardiovascular diseases. Impairment of endothelial function, arterial stiffness, inflammation, lipid modification as well as an alteration of antithrombotic and prothrombotic factors are smoking-related major determinants of initiation, and acceleration of the atherothrombotic process, leading to cardiovascular events. Cigarette smoking acutely exerts an hypertensive effect, mainly through the stimulation of the sympathetic nervous system. As concern the impact of chronic smoking on blood pressure, available data do not put clearly in evidence a direct causal relationship between these two cardiovascular risk factors, a concept supported by the evidence that no lower blood pressure values have been observed after chronic smoking cessation. Nevertheless, smoking, affecting arterial stiffness and wave reflection might have greater detrimental effect on central blood pressure, which is more closely related to target organ damage than brachial blood pressure. Hypertensive smokers are more likely to develop severe forms of hypertension, including malignant and renovascular hypertension, an effect likely due to an accelerated atherosclerosis
Hypertension in the elderly: an evidence-based review.
No full textThe progressive ageing of world population, and the increasing prevalence hypertension in elderly people are leading to the consideration that hypertension in the elderly is one of the main topic in hypertension treatment. Multiple mechanisms, including stiffening of large arteries, endothelial dysfunction, cardiac remodeling, autonomic dysregulation, renal aspects, contribute to the great prevalence of hypertension in the elderly and to increased cardiovascular morbidity and mortality. Treatment of hypertension can hardly put back older patients in a low risk category, especially if target organ damage is present. Nevertheless, blood pressure control can successfully prevent stroke, cognitive decline, coronary heart disease and heart failure, and reduce mortality in the elderly, and even in patients > 80 years, as recently demonstrated. Blood pressure should be lowered below 140/90 mmHg also in older patients. However the HYVET study suggests that a goal of 150/90 mmHg can be reasonable in patients aged 80 years or more. Drug treatment should be titrated with particular caution to adverse responses and excessive blood pressure lowering
