Randomized Controlled Trial
Oral magnesium supplementation reduces the incidence of gastrointestinal complications following cardiac surgery: a randomized clinical trial.
Gastrointestinal complications are common after coronary artery bypass graft surgery. These complications are ranged from nausea and vomiting to mesenteric ischemia and liver failure. It seems that nausea, vomiting, and constipation are related to magnesium deficiency. ⋯ Our data showed that oral magnesium supplementation could reduce the postoperative complications. Despite the better status in the intervention group, the hypomagnesemia was present in many of intervention group patients. It seems that supplementation with higher doses is needed.

The metabolic syndrome is a cluster of common pathologies: abdominal obesity linked to an excess of visceral fat, insulin resistance, dyslipidemia and hypertension. This syndrome is occurring at epidemic rates, with dramatic consequences for human health worldwide, and appears to have emerged largely from changes in our diet and reduced physical activity. An important but not well-appreciated dietary change has been the substantial increase in fructose intake, which appears to be an important causative factor in the metabolic syndrome. ⋯ Potential mechanisms include the priming of phagocytic cells, the opening of calcium channels, activation of N-methyl-D-aspartate (NMDA) receptors, the activation of nuclear factor-kappaB (NFkB) and activation of the renin-angiotensin system. Since magnesium deficiency has a pro-inflammatory effect, the expected consequence would be an increased risk of developing insulin resistance when magnesium deficiency is combined with a high-fructose diet. Accordingly, magnesium deficiency combined with a high-fructose diet induces insulin resistance, hypertension, dyslipidemia, endothelial activation and prothrombic changes in combination with the upregulation of markers of inflammation and oxidative stress.

Review Comparative Study
Magnesium chloride or magnesium sulfate: a genuine question.
MgSO4 is routinely used in therapeutics despite its toxicity. The aim of the present review was to compare MgSO4 and MgCl2 effects in order to answer the question whether MgSO4 could be or not replaced by MgCl2. Considering that the two salts have both similar and proper effects, a clear-cut conclusion is not easy to draw. However, choosing MgCl2 seems advisable because of its more interesting clinical and pharmacological effects and its lower tissue toxicity as compared to MgSO4.

Randomized Controlled Trial
Systemic magnesium to improve quality of post-surgical recovery in outpatient segmental mastectomy: a randomized, double-blind, placebo-controlled trial.
It remains to be determined if perioperative systemic magnesium can improve postoperative quality of recovery of patients undergoing ambulatory procedures. The main objective of the current investigation was to evaluate the effect of systemic magnesium on postoperative quality of recovery in patients undergoing outpatient segmental mastectomies. ⋯ Systemic magnesium improves postoperative quality of recovery in patients undergoing outpatient segmental mastectomy. Systemic magnesium is a safe, inexpensive, efficacious strategy to improve quality of recovery after ambulatory surgery.

Randomized Controlled Trial Multicenter Study
The effect of hypermagnesemic treatment on cerebrospinal fluid magnesium level in patients with aneurysmal subarachnoid hemorrhage.
Preliminary evidence has suggested that magnesium sulfate infusion reduces delayed ischemic neurological deficit and improves clinical outcome after aneurysmal subarachnoid hemorrhage. However, little is known about its site of action in vivo. We studied 22 aneurysmal subarachnoid hemorrhage patients with or without magnesium sulfate infusion for 10-14 days. ⋯ We found that the magnesium sulfate infusion bought an 11% to 21% increase in cerebrospinal fluid magnesium. The elevation of cerebrospinal fluid magnesium was sustained for at least nine days. Whether this mild elevation in cerebrospinal fluid magnesium level was adequate for neuroprotection awaits the results of ongoing clinical trials.
