I am very satisfied with the BPG Group’s editorial process. It is efficient and relatively fast compared with many other journals. Regarding the World Journal of Nephrology, I am always pleased to continue contributing with our research. As the corresponding author, I speak on behalf of all my coauthors when I say that we are glad to publish an update on hyponatremia, covering both fundamental concepts and recent advances. In internal medicine and nephrology, hyponatremia is an issue we encounter almost daily during bedside rounds. Because of this, it is a topic that clinicians must understand well, as it frequently arises during patient discussions and clinical decision-making at the bedside.
