Background: The parathyroid calcium-sensing receptor (CASR) controls the release of parathyroid hormone (PTH) in response to changes in serum calcium levels. Activation of the renal CASR increases urinary calcium excretion and is particularly important when CASR-dependent reductions in PTH fail to lower serum calcium. However, the role of the renal CASR in protecting against hypercalcemia and the direct effects of chronic CASR activation on tubular calcium handling remains to be fully elucidated.

Diuretic drugs act on electrolyte transporters in the kidney to induce diuresis and are often used in chronic kidney disease (CKD), given that nephron loss creates a deficit in the ability to excrete dietary sodium, which promotes an increase in plasma volume. This rise in plasma volume is exacerbated by CKD-induced systemic and intra-renal activation of the renin-angiotensin-aldosterone-system, which further limits urinary sodium excretion. In the absence of a compensatory decrease in systemic vascular resistance, increases in plasma volume induced by sodium retention can manifest as a rise in systemic arterial blood pressure.

: Vitamin D receptor (VDR) agonists are commonly used in clinical practice for their roles in calcium regulation and potential benefits in various diseases. However, their safety profiles, particularly for compounds available as food supplements, remain underexplored in real-world settings. This study aimed to analyze the safety profiles of VDR agonists using the EudraVigilance database, focusing on adverse drug reactions (ADRs) reported between 1 January 2004 and 23 June 2024.

Zoledronic acid (ZA), a bisphosphonate, is commonly used in breast cancer patients with bone metastases to treat hypercalcemia and osteolysis. Recent studies showed the anti-cancer effects of ZA in breast cancer. This study further explored the synergistic effects of sequential and nonsequential ZA and doxorubicin (DOX) administration on estrogen receptor (ER)-positive and -negative breast cancer cell lines.

Background: Magnesium sulfate (MgSO) is a tocolytic agent used to treat gestational hypertension and to prevent preterm labor. Neonatal hypocalcemia is a well-known side effect of maternal MgSO use. Cases of neonatal hypercalcemia after maternal MgSO have been reported.
