PENGARUH KEMUDAHAN PENGGUNAAN, KEMANFAATAN, DAN KEAMANAN TERHADAP MINAT PENGGUNAAN BERULANG PADA SHOPEEPAY

This study aims to determine the influence of Ease of Use, Usefulness, and Security on the intention of repeated use among students of the Faculty of Economics and Business at the University of Muhammadiyah Malang, both simultaneously and partially. The sample in this study consists of 97 students, using probability sampling techniques. The collected data were analyzed using multiple regression analysis to link the independent variables and the dependent variable. The results of the study indicate that Ease of Use, Usefulness, and Security have a positive and significant effect on the intention of repeated use. The more ease, benefits, and security perceived, the more interest there is in using Shopeepay repeatedly

Hypercalcemia-Induced Hypokalemic Metabolic Alkalosis in a Multiple Myeloma Patient: The Risk of Furosemide Use

Hypercalcemia is often seen in patients with malignancies, and in the past treatment for this has traditionally included loop diuretics. Clinically, patients with hypercalcemia frequently present with polyuria and volume contraction which may be further exacerbated by diuretic therapy. In the lab, hypercalcemia has been shown to activate the calcium-sensing receptor in the thick ascending limb of Henle and inactivate the 2 chloride sodium potassium co-transporter and induce a hypokalemic metabolic alkalosis, an effect similar to that of the loop diuretic furosemide. We now report what may well be the first clinical correlate of this laboratory finding in a patient who developed a hypokalemic metabolic alkalosis as a consequence of severe hypercalcemia due to multiple myeloma and whose metabolic derangement was corrected without the use of a loop diuretic which may have exacerbated the electrolyte abnormalities
