AIM: The association of sodium (Na) and potassium (K) intake with blood pressure (BP) is an ongoing debate, especially in central Iran. We aimed to examine the mean Na and K intake, major sources of Na and the relationship between BP and dietary and urinary Na and K. METHODS: This cross-sectional study was performed in central Iran in 2013-2014. A total of 796 non-hypertensive adults aged >18 years were randomly recruited. The semi-quantitative food frequency questionnaire was used to assess dietary Na and K intake...

Primary aldosteronism (PA) is the most common form of secondary hypertension (HTN), with an estimated prevalence of 4% of hypertensive patients in primary care and around 10% of referred patients. Patients with PA have higher cardiovascular morbidity and mortality than age- and sex-matched patients with essential HTN and the same degree of blood pressure elevation. PA is characterized by an autonomous aldosterone production causing sodium retention, plasma renin supression, HTN, cardiovascular damage, and increased potassium excretion, leading to variable degrees of hypokalemia...

Cardiovascular risk management is an integral part of treatment in Type 2 Diabetes Mellitus (T2DM), and requires pharmacological as well as nutritional management. We hypothesize that a systematic assessment of both pharmacological and nutritional management can identify targets for the improvement of treatment quality. Therefore, we analysed blood pressure (BP) management in the DIAbetes and LifEstyle Cohort Twente (DIALECT). DIALECT is an observational cohort from routine diabetes care, performed at the ZGT Hospital (Almelo and Hengelo, The Netherlands)...

REVIEW
Toshiyuki Iwahori, Katsuyuki Miura, Hirotsugu Ueshima
Pathogenetic studies have demonstrated that the interdependency of sodium and potassium affects blood pressure. Emerging evidences on the sodium-to-potassium ratio show benefits for a reduction in sodium and an increase in potassium compared to sodium and potassium separately. As presently there is no known review, this article examined the practical use of the sodium-to-potassium ratio in daily practice. Epidemiological studies suggest that the urinary sodium-to-potassium ratio may be a superior metric as compared to separate sodium and potassium values for determining the relation to blood pressure and cardiovascular disease risks...

Food in industrialized countries is rich in processed products with a high sodium and low potassium content. There is abundant evidence in the literature depicting the relationship between a high daily sodium/potassium intake ratio and the high prevalence of arterial hypertension in modern societies. There is also increasing evidence suggesting a blood pressure lowering effect of potassium, especially in cases of high sodium intake or in patients with increased salt sensibility. Our dietary advice for the prevention and treatment of hypertension should follow a thorough evaluation of our patients' daily nutritional habits and should not only focus on sodium intake but also aim for a balanced sodium/potassium uptake...

The substitution of potassium ions (K(+)) by sodium ions (Na(+)) in the nutrition of plants is restricted. It was shown earlier that net protein synthesis is the process which is most sensitive to the substitution of K(+) by Na(+) in young sugar beet. We hypothesized that the activity of ribosomes is inhibited by the substitution. This hypothesis was tested in an in vitro approach. Cytosolic polysomes were isolated from growing leaves of sugar beet and maize by means of differential centrifugation. In vitro systems of both plant species were tested for functionality and comparability...

Estimation of dietary sodium intake is problematic. The most accurate measure is average sodium excretion from multiple 24 hour urine collections, but such an approach is impractical. Using data from the Women's Health Initiative, Prentice and colleagues assessed the relationship of calibrated estimates of sodium and potassium excretion with cardiovascular outcomes. The calibrated estimates are a function of self-reported sodium/potassium ratio from a food frequency questionnaire, age, body mass index, race, supplement use, smoking status, education, income, and aspirin use...

Studies of sodium and potassium intake and cardiovascular disease incidence often rely on self-reported dietary data. Here self-reported intakes from postmenopausal women at 40 participating U.S. clinical centers are calibrated using 24-hour urinary excretion measures in Women's Health Initiative cohorts, with follow-up over 1993-2010. Hypertension incidence related positively to (calibrated) sodium intake and to the ratio of sodium-to-potassium. The sodium-to-potassium ratio was associated with cardiovascular disease incidence during a 12-year average follow-up period...

Kochujang, a Korean fermented soybean-based red pepper paste, has been reported to have beneficial health effects. The aim of this study was to examine the antiobesity effects of Kochujang as a supplement in overweight/obese subjects according polymorphisms in the obesity-linked gene, peroxisome proliferator activator receptor γ (PPARγ2). Sixty overweight/obese subjects, who had body mass indexes (BMI, kg/m(2)) ≥23 or waist/hip ratios (WHR) ≥0.90 for males or ≥0.85 for females, were randomly assigned to either taking 32 g/day of placebo or Kochujang for 12 weeks...

BACKGROUND: Many studies have determined that dehydration is an independent predictor of outcome after ischemic stroke (IS); however, none have determined if the use of thrombolytic therapy modifies the negative impact of poor hydration. To inform the stroke registry established at our institution, we conducted a retrospective study to determine if dehydration remains a negative prognostic factor after IS patients treated with tissue plasminogen activator (tPA). METHODS: Between 2007 and 2012, we recruited 382 subjects; 346 had data available and were divided into 2 groups on the basis of their blood urea nitrogen/creatinine (BUN/Cr) ratio...

BACKGROUND: Diabetes is the most common cause of end-stage renal disease and is associated with increased mortality. Although only a proportion of type 2 diabetic subjects develop albuminuria or progress, it is not currently possible to identify those patients who will develop this complication or who will progress. AIM: The aim of the study was to identify baseline risk factors for the development and progression of albuminuria in a cohort with type 2 diabetes and use this data to generate risk equations...

BACKGROUND: The importance of vasopressin and/or urine concentration in various kidney, cardiovascular, and metabolic diseases has been emphasized recently. Due to technical constraints, urine osmolality (Uosm), a direct reflect of urinary concentrating activity, is rarely measured in epidemiologic studies. METHODS: We analyzed 2 possible surrogates of Uosm in 4 large population-based cohorts (total n = 4,247) and in patients with chronic kidney disease (CKD, n = 146)...

Lowering sodium intake with a reduced-sodium, added potassium salt substitute has been proved to lower blood pressure levels. Whether the same strategy will also reduce the risks of vascular outcomes is uncertain and controversial. The SSaSS has been designed to test whether sodium reduction achieved with a salt substitute can reduce the risk of vascular disease. The study is a large-scale, open, cluster-randomized controlled trial done in 600 villages across 5 provinces in China. Participants have either a history of stroke or an elevated risk of stroke based on age and blood pressure level at entry...
