Sodium and potassium urinary excretion and dietary intake: a cross-sectional analysis in adolescents.
CONCLUSIONS: Adolescents had a high-sodium and low-potassium diet, well above the WHO recommendations. Health promotion interventions are needed in order to decrease sodium and increase potassium intake. PMID: 27072344 [PubMed]

Systematic review and meta-analysis of randomised controlled trials on the effects of potassium supplements on serum potassium and creatinine
Conclusions In short-term studies of relatively healthy persons, a moderate oral potassium supplement resulted in a small increase in circulating potassium levels and no change in renal function.

Potassium channel expression and function in microglia: Plasticity and possible species variations.
Authors: Nguyen HM, Blomster LV, Christophersen P, Wulff H Abstract Potassium channels play important roles in microglia functions and thus constitute potential targets for the treatment of neurodegenerative diseases like Alzheimer's, Parkinson's and stroke. However, uncertainty still prevails as to which potassium channels are expressed and at what levels in different species, how the expression pattern changes upon activation with M1 or M2 polarizing stimuli compared to more complex exposure paradigms, and - most importantly - how these findings relate to the in vivo situation. In this mini-review we discuss the ...

Potassium 2-(1-hydroxypentyl)-benzoate attenuates neuronal apoptosis in neuron –astrocyte co-culture system through neurotrophy and neuroinflammation pathway
In conclusion, the present study demonstrates that the neuroprotective effects of d,l-PHPB were improved by astrocytes, mainly mediated by increasing the release of BDNF/NGF and attenuating inflammatory cytokines. Graphical abstract

Supplement warning: Overdosing on this to lower high blood pressure could be deadly
SUPPLEMENTS popularly used include vitamin C, vitamin D3 and omega-3 - and potassium may also be taken to ward off high blood pressure, heart disease, stroke, arthritis, cancer, digestive disorders, and infertility. However, too much of the mineral could be deadly.

Revised Reference Values for Potassium Intake
Conclusions: The consumption of potassium-rich foods should be generally increased. Supplemental intake beyond the estimated values has no health benefit and is therefore not recommended.Ann Nutr Metab 2017;71:118-124

Comparisons of cardiometabolic biomarkers, lifestyle behaviors, and dietary sodium and potassium intake in a representative sample of Korean adults with and without cardio-cerebrovascular diseases
Conclusion The cardiometabolic condition varied, with hypertensives having a higher prevalence for obesity, high blood pressure, and cholesterol; poorer adherence to the behavioral recommendations was also noted in cardio-cerebrovascular diseases. Such variations in cardiovascular risks would provide implications for addressing vulnerability across groups.

Activity-dependent changes in transporter and potassium currents in hippocampal astrocytes.
Abstract Astrocytes are involved in maintenance of synaptic microenvironment by glutamate uptake and K(+) clearance. These processes are associated with net charge transfer across the membrane and therefore can be recorded as glutamate transporter (IGluT) and K(+) (IK) currents. It has been previously shown that the blockade of IK with BaCl2 enhances the IGluT. Here we show that activity-dependent facilitation (5 stimuli at 50Hz) of IGluT was not significantly different in BaCl2 compared to facilitation of IGluT isolated by post-hoc subtraction of IK. Nevertheless, BaCl2 abolished the activity-dependent prolongati...

Conversion and pharmacokinetics profiles of a novel pro-drug of 3-n-butylphthalide, potassium 2-(1-hydroxypentyl)-benzoate, in rats and dogs.
In this study, we investigated the conversion and pharmacokinetics profiles of dl-PHPB in vitro and in vivo. The conversion of dl-PHPB to dl-NBP was pH- and calcium-dependent, and paraoxonase was identified as a major enzyme for the conversion in rat plasma. The pharmacokinetics, tissue distribution and excretion of dl-PHPB were studied and compared with equal-molar doses of dl-NBP in rats and dogs. The in vivo studies showed that dl-PHPB could be quickly and completely converted to dl-NBP. The plasma concentration-time course of converted dl-NBP after intravenous dl-PHPB administration was nearly the same as that after eq...

How too little potassium may contribute to cardiovascular disease
In mouse studies, scientists found a mechanism that may explain why low levels of potassium in the diet have been linked to high blood pressure, heart disease, and stroke in people.

Benefit and risk assessment of increasing potassium intake by replacement of sodium chloride with potassium chloride in industrial food products in Norway.
In conclusion, the number of Norwegians facing increased risk is far greater than the number likely to benefit from this replacement of sodium with potassium in industrially produced food. PMID: 29175183 [PubMed - as supplied by publisher]

The kidney and cardiovascular outcome trials
Chronic kidney disease (CKD) affects a substantial minority of people with type 2 diabetes (T2D). Analysis of US National Health and Nutrition Examination Survey (NHANES) datasets from 2007 through 2012 showed Stage 3 or worse disease (estimated glomerular filtration rate [eGFR] <60 mL/min per 1.73 m2) in nearly one in five patients, with increasing age, blood pressure, obesity, and levels of glycemia all associated with higher likelihood of Stage 3 or worse CKD, comparable to findings from surveys from many other areas, which also show micro‐ or macroalbuminuria to be present in one‐sixth to one‐third of diab...

Taste perception and diet in people of Chinese ancestry.
CONCLUSIONS: There was a salty-sour confusion among Singaporean Chinese unlike the bitter-sour confusion reported for Caucasians. Most sodium came from sauces and was added during food preparation. In programs to address sodium: potassium ratio excess among Chinese prone to hypertension and stroke, sour as well as salty taste may need to be considered. PMID: 29384339 [PubMed - in process]
