Potassium
Adv Food Nutr Res. 2021;96:89-121. doi: 10.1016/bs.afnr.2021.02.013. Epub 2021 May 24.ABSTRACTPotassium is an essential nutrient that performs a vital role in cellular functions including maintaining fluid balance and osmolality of cells. Potassium balance is maintained by the kidney and the majority of ingested potassium is excreted in the urine. There is strong evidence of a negative association between dietary potassium and blood pressure, and some evidence (much of it indirect) of negative associations between dietary potassium and cardiovascular disease (particularly stroke and coronary heart disease) and kidney disea...

Association of Initial Potassium Levels with the Type of Stroke in the Emergency Department
Early differentiation of hemorrhagic stroke from ischemic stroke in patients with suspected stroke is essential for subsequent management of the patient. While serum potassium level has been suggested as a marker of acute hemorrhagic conditions,1, 2 little is known about whether the initial serum potassium levels differ based on the type of stroke. If serum potassium levels can help differentiate hemorrhagic stroke from ischemic stroke, this information can be applied in deciding subsequent treatment procedures (e.g., catheter intervention, tissue plasminogen activator administration, and antihypertensive therapy) in setti...

Postoperative malignant hyperthermia confirmed by calcium-induced calcium release rate after breast cancer surgery, in which prompt recognition and immediate dantrolene administration were life-saving: a case report
ConclusionsThe occurrence of MH can be life-threatening, but its frequency is very low, and genetic testing and muscle biopsy are required to confirm the diagnosis. On retrospective evaluation using the malignant hyperthermia scale, the present case was almost certainly that of a patient with MH. Prompt recognition and immediate treatment with dantrolene administration and body cooling effectively reversed a potentially fatal syndrome. This was hence a valuable case of a patient with postoperative MH that led to a confirmed diagnosis by CICR.
