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...

Association of Dyskalemias with Ischemic Stroke in Advanced Chronic Kidney Disease Patients Transitioning to Dialysis
CONCLUSION: In patients with advanced CKD, hypokalemia (chronic exposure) was associated with a higher risk of ischemic stroke, whereas hyperkalemia (acute exposure) was associated with a lower risk of ischemic stroke. Further studies in this population are needed to explore the mechanisms underlying these associations.PMID:34289468 | DOI:10.1159/000516902

Predictors of Survival in Chronic Hemodialysis Patients: A 10-Year Longitudinal Follow-Up Analysis
CONCLUSION: In chronic hemodialysis patients, targets to improve the short-term prognosis and long-term prognosis are not equivalent. Hyperphosphatemia was a significant risk factor for the all-cause mortality among patients with normal serum albumin levels but not among patients with compromised albumin levels.PMID:33756478 | DOI:10.1159/000513951

Premature Stroke Secondary to Severe Hypertension Results from Liddle Syndrome Caused by a Novel SCNN1B Mutation
Conclusions:We identified a novelSCNN1B mutation (c.1849C#x3e;A) in a family affected by LS. Patients with LS, especially those with severe hypertension, should be alert for the occurrence of premature stroke. Timely diagnosis using genetic testing and tailored treatment with amiloride can help LS patients to avoid severe complications.Kidney Blood Press Res
