In the present study, we evaluated whether mild Mg deficiency affects growth, behaviour, and plasma and urinary metabolomes in rats. Mg levels in plasma and the femur, and urinary Mg excretion decreased by consuming a mildly low Mg diet, whereas body weight and food intake were not affected. Also, anxiety- and depression-like behaviours were not affected by Mg deficiency. These results indicate that the negative effects observed here are milder than those for severe Mg deficiency, as previously reported. Of the 93 annotated metabolites in plasma, only glycylglycine was moderately affected. Of the 122 annotated metabolites in urine, 29 were affected.

This study aimed to investigate the association between dietary magnesium intake, magnesium depletion score (MDS) and hyperuricemia-related all-cause mortality or cardiovascular mortality in patients with CHS. In this retrospective cohort study, 1,823 CHD patients were selected from the National Health and Nutrition Examination Survey (NHANES). Dietary magnesium intake was determined based on 24-hour dietary recall interviews. MDS was assessed considering four factors: use of diuretics, use of proton pump inhibitors, estimated glomerular filtration rate, and alcohol consumption. Weighted univariate and multivariate Cox regression models were applied to explore the association between dietary magnesium intake, MDS, hyperuricemia, and all-cause mortality or cardiovascular mortality. The results were presented as hazard ratios (HRs) and 95% confidence intervals (CIs). The Kaplan-Meier survival curves were used to explore survival status relative to magnesium intake or MDS. After an average of 81 months of follow-up, 879 CHD patients died. After adjusting for covariates, MDS ≥2 (HR=1.34, 95% CI: 1.13-1.60) and hyperuricemia (HR=1.25, 95% CI: 1.01-1.55) were associated with increased odds of all-cause mortality.

The steep Trendelenburg position and a high intra-abdominal pressure can render patients susceptible to AKI after surgery. This study aimed to evaluate the effects of intraoperative magnesium sulphate administration on postoperative AKI in patients who underwent RARP. This retrospective study used a propensity score-matched analysis to evaluate the medical records of patients who underwent RARP between May 2013 and December 2021 in a single institution. In total, 3,239 cases were reviewed. After propensity score matching, 456 patients were each included in the magnesium and control groups. Univariate and multivariate logistic regression analyses were conducted to identify risk factors for postoperative AKI, as defined by the Kidney Disease Improving Global Outcomes criteria, within seven days after surgery. The incidence of postoperative AKI did not differ significantly between the magnesium and control groups (30.7% versus 31.4%). The univariate logistic regression analysis revealed that intraoperative magnesium sulphate administration was not associated with AKI after RARP (p=0.83). In the multivariate analysis, body mass index (odds ratio [OR], 1.069; p=0.018) and duration of surgery (OR, 1.005; p=0.027) were independent risk factors, while total intravenous anaesthesia (OR, 0.448; p=0.005) and intraoperative fluid replacement (OR, 0.856; p=0.012) were protective factors for postoperative AKI.
