Abstract
Sirtuins (SIRTs) are a class of nicotine adenine dinucleotide (NAD+)-dependent proteins which participate in numerous molecular pathways involved in various age-related human diseases, such as type II diabetes, cardiovascular (CV) diseases and cancer. They have a major role in apoptosis, inflammation, oxidative stress and metabolism regulation, traits that have a great impact on CV physiology and pathology. Their unique profile of NAD+ energy dependency makes them an appealing target for human intervention in cellular and metabolic processes. This review focuses on the recent advances of SIRTs research aiming to shed light on the emerging roles of SIRTs in the pathophysiology of CV and metabolic diseases.

Abstract
Age-related macular degeneration (AMD) is one of the main causes of vision loss, especially in the elderly. The involvement of essential hypertension in its pathogenesis has been well covered in the literature since it was first recognized. Hemodynamic abnormalities appear to contribute to AMD, with the renin-angiotensin system playing a significant role. Many studies have demonstrated that high blood pressure is associated with lower choroidal blood flow and disturbed vascular homeostasis in these patients. In addition, AMD is characterized by abnormal neovascularization, to which angiotensin II and growth factors make a large contribution. Most epidemiological studies have found essential hypertension to be a risk factor for AMD. However, although all agree that the strongest predisposing factors are age and smoking, overall there is some inconsistency regarding the exact role of hypertension in its pathogenesis. In particular, there are no data in the literature to support the view that antihypertensive medication and the successful management of hypertension have a positive effect on the clinical outcome of AMD. This reinforces the data indicating that the cause of AMD is multifactorial and suggests that, although essential hypertension probably plays a role, in itself it is unlikely to be a major contributor to the future occurrence of AMD.

Abstract
Depression is a common mental health issue worldwide leading to disability, functional decline and increased mortality. Novel antidepressants have been developed during the last decades in order to treat depression syndromes. Some evidence suggests that major depression has been associated with the development of congestive heart failure and with adverse outcomes in patients with coronary heart disease. The purpose of the present article is to review the impact of novel antidepressant patent drugs on cardiovascular disease and arterial hypertension.

Abstract
Canagliflozin-with the patent number WO2011142478A1- belongs to a novel class of antidiabetic drugs known as SGLT2 inhibitors, which has been approved by FDA in March 2013. This medication acts through the inhibition of glucose reabsorption in the kidney resulting in glucosuria and thus lowering of glucose blood levels. There are several phase III clinical ongoing trials involving this new class of medications. So far promising results have been shown. This review article summarizes current knowledge regarding the novel SGLT2 inhibitor canagliflozin and its future perspectives in the treatment of type 2 diabetes mellitus.

Abstract
The present study attempts to offer insight into the volume, cost, and productivity of the operation of a cardiac echocardiographic laboratory (echo-lab) in a major public hospital of Greece and thus to contribute, on a practical level, to the widening of knowledge in the strategic field of secondary and tertiary healthcare management. The conducted research includes the basic step of the deployment of a primary data registry in the echo-lab and unfolds in three levels, i.e. the variability measurement of the quantity and cost of medical services provided to different patient populations, the assessment of operating costs and the development of productivity indexes. The results show that the mean costs of provision do change among distinct patient populations. The most important, from a financial standpoint, population cluster appears to be the one corresponding to outpatients. Productivity indices presented in this analysis constitute an essential piece of information which the public healthcare system is currently largely lacking, and which, combined with the pricing and the diagnosis-related group coding system of hospitals, can be used to improve efficiency in the management of secondary and tertiary care.
