INTRODUCTION: Hypertension (HTN), being a major risk factor for cardiovascular diseases (CVDs), is an important issue of medical and public health. High blood pressure (BP) is ranked as the third most important risk factor for attributable burden of disease in south Asia (2010). Hypertension (HTN) exerts a substantial public health burden on cardiovascular health status and healthcare systems in India. Uncontrolled hypertension among adults with hypertension is associated with increased mortality...

Excessive dietary salt (sodium chloride) intake is associated with an increased risk for hypertension, which in turn is especially a major risk factor for stroke and other cardiovascular pathologies, but also kidney diseases. Besides, high salt intake or preference for salty food is discussed to be positive associated with stomach cancer, and according to recent studies probably also obesity risk. On the other hand a reduction of dietary salt intake leads to a considerable reduction in blood pressure, especially in hypertensive patients but to a lesser extent also in normotensives as several meta-analyses of interventional studies have shown...

Recent findings regarding the influence of the microbiota in many inflammatory processes have provided a new way to treat diseases. Now, one may hypothesize that the origin of a plethora of diseases is related to the health of the gut microbiota and its delicate, although complex, interface with the epithelial and immune systems. The 'westernization' of diets, for example, is associated with alterations in the gut microbiota. Such alterations have been found to correlate directly with the increased incidence of diabetes and hypertension, the main causes of chronic kidney diseases (CKDs), which, in turn, have a high estimated prevalence...

BACKGROUND: Whether polyunsaturated fatty acids (PUFA) are associated with end-stage renal disease (ESRD) in populations with a high burden of risk factors for kidney disease is unknown. We sought to determine whether PUFA intake is associated with ESRD. METHODS: We conducted a nested case-control study of ESRD within the Southern Community Cohort Study (SCCS), a prospective cohort of low-income blacks and whites in the southeastern US (2002-2009). Through 2012, 1,074 incident ESRD cases were identified by linkage with the United States Renal Data System and matched to 3,230 controls by age, sex and race...

The Mediterranean diet is upheld in the 2015-2020 Dietary Guidelines as an example of an eating pattern that promotes good health, a healthy body weight, and disease prevention throughout the lifespan. The Mediterranean eating pattern is based on a variety of unprocessed plant foods including fruits, vegetables, whole grains, legumes, nuts, and seeds that are high in polyphenols. The majority of polyphenols arrive in the colon where bacteria degrade them into smaller phenolics that can be translocated via the portal vein to the liver...

Management of hypertension in diabetes is critical for reducing cardiovascular mortality and morbidity. Dietary approaches for controlling high blood pressure have historically focused on sodium. Thus, many guidelines recommend that patients with type 2 diabetes reduce high sodium intake. Nonetheless, the potential benefits of sodium reduction are debatable. The kidney has a crucial role in glucose filtration and reabsorption in addition to its regulation of fluid and electrolyte homeostasis. A key factor linking sodium uptake and glucose transport is the sodium-glucose cotransporter 2 (SGLT2) in renal proximal tubular cells...

A healthy lifestyle is important in CVD prevention and treatment through effects on modifiable CVD risk factors, particularly blood pressure. Although the major drawback is the low level of adherence over time, appropriate lifestyle changes may safely and effectively prevent and treat hypertension. The recommended dietary approaches that have been shown to be capable of reducing blood pressure are: salt restriction, moderation of alcohol consumption, high consumption of vegetables and fruits and low-fat and other types of diet, and weight reduction...

OBJECTIVE: Obesity during pregnancy is associated with a greater risk of developing hypertension in the offspring. Plasma leptin levels correlate strongly with blood pressure and renal sympathetic nerve activity (RSNA). The ventromedial hypothalamus (VMH) is a key centre of energy homeostasis, haemodynamic and sympathetic tone to renal vasculature. It is possible that exposure to over-nutrition during development change the activity of the neurons, amplifying sympathetic output leading to hypertension in the offspring...

OBJECTIVE: Hypertension affects one third of the population around the world and is a major contributor to cardiovascular disease. There is strong evidence that the main cause of hypertension is increases sympathetic nerve activity to specific organs. Plasma leptin levels correlate with blood pressure (BP) and renal sympathetic nerve activity (RSNA). The central effects of leptin are mediated primarily through the arcuate (ARC) nucleus of the hypothalamus. Both neuropeptide-Y (NPY) and alpha-melanocyte stimulating hormone (α-MSH) containing neurons ascend from the ARC and terminate in ventromedial hypothalamus (VMH) which are the key centres of energy homeostasis, hemodynamics and sympathetic tone to renal vasculature...

OBJECTIVE: It has been reported that obesity-related high blood pressure was partly associated with increased aldosterone secretion and/or activity, but detailed mechanisms are not known. Our previous study suggested that different salt contents in each diet would affect the aldosterone levels. In this study, we investigated the change of aldosterone secretion and MR sensitivity of obesity mice by high fat diet under equally-adjusted salt intake. DESIGN AND METHOD: We prepared normal fat diet (NFD, 10% lard) and high fat diet (HFD, 60% lard) with equal amount of salt based on the amount of food intake of C57BL/6J mice...

OBJECTIVE: It has been indicated that non-dipper pattern of circadian rhythm of blood pressure (BP) is a great risk of cardiovascular disease, which is accompanied by impaired renal function and proteinuria. Here, we aimed to investigate the circadian rhythm of BP during the progression of renal injury in Dahl salt-sensitive (DSS) hypertensive rats. DESIGN AND METHOD: DSS rats were treated with a high salt diet (HS; 8% NaCl) for 10 weeks (n = 10). RESULTS: Before starting a HS diet, the difference in mean arterial pressure (MAP) between dark and light period was 6...

OBJECTIVE: Claudins are tight junction proteins that regulate paracellular permeability of renal epithelia, and renal paracellular sodium chloride permeability may be essential to salt homeostasis and blood pressure control. A previous study has shown that the collecting duct-specific claudin-4 knockout animals develop hypotension due to profound renal wasting of chloride. This study was undertaken to investigate whether claudins have a role in the hypertension of Dahl salt-sensitive (DS) rats...
