Less Sodium, More Potassium, or Both: Population-wide Strategies to Prevent Hypertension
Am J Physiol Renal Physiol. 2023 Jun 1. doi: 10.1152/ajprenal.00007.2023. Online ahead of print.ABSTRACTHypertension is among the most prevalent medical conditions globally and a major contributor to chronic kidney disease, cardiovascular disease, and death. Prevention through non-pharmacologic, population-level interventions is critically needed to halt this worldwide epidemic. However, there are ongoing debates as to where public policy efforts should focus. Recently the Salt Substitute and Stroke Study demonstrated the efficacy of substituting table salt with potassium salt to reduce the risk of stroke, major cardiovasc...

Should we liberalize potassium intake in CKD? No, we should not
Although a high dietary sodium (Na) intake has dominated our understanding of pathophysiology of hypertension, the moderating effects of a dietary potassium (K) intake on blood pressure (BP) are less appreciated. K depletion in normotensive men can increase BP,1 supplementation of K among normotensive women can modestly lower 24-hour ambulatory BP,2 and in those with untreated hypertension3 or among those with hypertension and hypokalemia provoked by diuretics, K supplementation can lower BP.4 A cluster randomized trial from 600 villages in China in people with a history of previous stroke (72.6%) or a history of hypertens...

Environmental circadian disruption suppresses rhythms in kidney function and accelerates excretion of renal injury markers in urine of male hypertensive rats.
Abstract Non-traditional work schedules, such as shift work, have been associated with numerous health issues including cardiovascular and metabolic disease. These work schedules can chronically misalign environmental timing cues with internal circadian clock systems in the brain and in peripheral organs, leading to dysfunction of those systems and their associated biological processes. Environmental circadian disruption in the kidney may be an important factor in the increased incidence of hypertension and adverse health outcomes in human shift workers. The relationship between renal rhythmicity and injury resili...
