Magnesium depletion score (MDS) is a scoring system developed to predict the status of Mg deficiency that considers the pathophysiological factors influencing the reabsorption capability of the kidneys. The primary outcome was all-cause mortality of CHF patients and the secondary outcome was mortality due to cardiovascular disease (CVD). Weighted univariate and multivariate cox proportional hazards models were used to explore the association between Mg status, serum VD concentration and all-cause mortality or mortality due to CVD in CHF patients, using hazard ratios (HRs) and 95 % confidence intervals (CIs).

Low levels of magnesium have been associated with accelerated dopaminergic cell loss in animal PD models, and magnesium has been shown to have a neuroprotective effect in PD models. Evidence of a low magnesium level in the brain of PD individuals, with a low magnesium level in the diet, increasing the risk of PD, further strengthens the role of magnesium deficiency in the pathogenesis of PD. The presence of low-level magnesium in brain tissue and high level in CSF and serum support the possibility of dysfunctional magnesium transporters in PD. Indeed, variants in magnesium transport channels, such as TRPM7 and SLC41A1, have been recently detected in PD individuals. Magnesium, being an NMDA antagonist, could also have a therapeutic role in levodopa-induced dyskinesia. There are no clinical studies indicating a neuroprotective role of magnesium in PD, however, the Mediterranean diet and variants of the diet have been associated with a lower risk of PD, which may be due to the magnesium-rich constituents of the diet.

Perioperative magnesium resulted in lower equivalent morphine consumption at 24 hours post-surgery (mean difference [MD]=-25.22 mg; p=0.04) and no effect at 48 hours (MD=-4.46 mg; p=0.19). Magnesium decreased heart rate (MD = -5.31 beats/min; p=0.0002) after tracheal intubation or after surgery, but had no effect on postoperative blood pressure (MD=-6.25 mmHg; p=0.11). There was a significantly higher concentration of magnesium in the magnesium group compared with that in the placebo group (MD = 0.91 mg/dL; p<0.00001). This meta-analysis provides evidence supporting perioperative magnesium as an analgesic adjuvant at 24 hours following thoracic surgery, but no opioid-sparing effect at 48 hours post-surgery. The severity of postoperative pain did not significantly differ between any of the postoperative time points, irrespective of magnesium. Further research on perioperative magnesium in various surgical settings is needed.</p>","PeriodicalId":18159,"journal":{"name":"Magnesium research","volume":"36 4","pages":"54-68"},"PeriodicalIF":1.5,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141492481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
