Review
Magnesium oxide has been widely used as a laxative for many years in East Asia, yet its prescription has largely been based on empirical knowledge. In recent years, several new laxatives have been developed, which has led to a resurgence in interest and increased scientific evidence surrounding the use of magnesium oxide, which is convenient to administer, of low cost, and safe. Despite these advantages, emerging clinical evidence indicates that the use of magnesium oxide should take account of the most appropriate dose, the serum concentration, drug-drug interactions, and the potential for side effects, especially in the elderly and in patients with renal impairment. The aim of this review is to evaluate the evidence base for the clinical use of magnesium oxide for treating constipation and provide a pragmatic guide to its advantages and disadvantages.

INTRODUCTION
Chronic idiopathic constipation (CIC) is a common disorder associated with significant impairment in quality of life. This clinical practice guideline, jointly developed by the American Gastroenterological Association and the American College of Gastroenterology, aims to inform clinicians and patients by providing evidence-based practice recommendations for the pharmacological treatment of CIC in adults.
METHODS
The American Gastroenterological Association and the American College of Gastroenterology formed a multidisciplinary guideline panel that conducted systematic reviews of the following agents: fiber, osmotic laxatives (polyethylene glycol, magnesium oxide, lactulose), stimulant laxatives (bisacodyl, sodium picosulfate, senna), secretagogues (lubiprostone, linaclotide, plecanatide), and serotonin type 4 agonist (prucalopride). The panel prioritized clinical questions and outcomes and used the Grading of Recommendations Assessment, Development, and Evaluation framework to assess the certainty of evidence for each intervention. The Evidence to Decision framework was used to develop clinical recommendations based on the balance between the desirable and undesirable effects, patient values, costs, and health equity considerations.
RESULTS
The panel agreed on 10 recommendations for the pharmacological management of CIC in adults. Based on available evidence, the panel made strong recommendations for the use of polyethylene glycol, sodium picosulfate, linaclotide, plecanatide, and prucalopride for CIC in adults. Conditional recommendations were made for the use of fiber, lactulose, senna, magnesium oxide, and lubiprostone.
DISCUSSION
This document provides a comprehensive outline of the various over-the-counter and prescription pharmacological agents available for the treatment of CIC. The guidelines are meant to provide a framework for approaching the management of CIC; clinical providers should engage in shared decision making based on patient preferences as well as medication cost and availability. Limitations and gaps in the evidence are highlighted to help guide future research opportunities and enhance the care of patients with chronic constipation.

Review
Implantation of cardiovascular stents is an important therapeutic method to treat coronary artery diseases. Bare-metal and drug-eluting stents show promising clinical outcomes, however, their permanent presence may create complications. In recent years, numerous preclinical and clinical trials have evaluated the properties of bioresorbable stents, including polymer and magnesium-based stents. Three-dimensional (3D) printed-shape-memory polymeric materials enable the self-deployment of stents and provide a novel approach for individualized treatment. Novel bioresorbable metallic stents such as iron- and zinc-based stents have also been investigated and refined. However, the development of novel bioresorbable stents accompanied by clinical translation remains time-consuming and challenging. This review comprehensively summarizes the development of bioresorbable stents based on their preclinical/clinical trials and highlights translational research as well as novel technologies for stents (e.g., bioresorbable electronic stents integrated with biosensors). These findings are expected to inspire the design of novel stents and optimization approaches to improve the efficacy of treatments for cardiovascular diseases.

Effects of Magnesium Citrate, Magnesium Oxide, and Magnesium Sulfate Supplementation on Arterial Stiffness: A Randomized, Double-Blind, Placebo-Controlled Intervention Trial.
Background Magnesium supplements may have beneficial effects on arterial stiffness. Yet, to our knowledge, no head-to-head comparison between various magnesium formulations in terms of effects on arterial stiffness has been performed. We assessed the effects of magnesium citrate supplementation on arterial stiffness and blood pressure and explored whether other formulations of magnesium have similar effects. Methods and Results In this randomized trial, subjects who were overweight and slightly obese received either magnesium citrate, magnesium oxide, magnesium sulfate, or placebo for 24 weeks. The total daily dose of magnesium was 450 mg/d. The primary outcome was carotid-to-femoral pulse wave velocity, which is the gold standard method for measuring arterial stiffness. Secondary outcomes included blood pressure and plasma and urine magnesium. Overall, 164 participants (mean±SD age, 63.2±6.8 years; 104 [63.4%] women) were included. In the intention-to-treat analysis, neither magnesium citrate nor the other formulations had an effect on carotid-to-femoral pulse wave velocity or blood pressure at 24 weeks compared with placebo. Magnesium citrate increased plasma (+0.04 mmol/L; 95% CI, +0.02 to +0.06 mmol/L) and urine magnesium (+3.12 mmol/24 h; 95% CI, +2.23 to +4.01 mmol/24 h) compared with placebo. Effects on plasma magnesium were similar among the magnesium supplementation groups, but magnesium citrate led to a more pronounced increase in 24-hour urinary magnesium excretion than magnesium oxide or magnesium sulfate. One serious adverse event was reported, which was considered unrelated to the study treatment. Conclusions Oral magnesium citrate supplementation for 24 weeks did not significantly change arterial stiffness or blood pressure. Magnesium oxide and magnesium sulfate had similar nonsignificant effects. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT03632590.

Randomized Controlled Trial
BACKGROUND AND OBJECTIVE
Restless legs syndrome/Willis-Ekbom Disease (RLS/WED) is one of the most prevalent sleep disorders. There are contradicting data about the effectiveness of magnesium and vitamin B6 in alleviating the symptoms of this condition. Therefore, this study aimed to assess the efficacy of magnesium and vitamin B6 in alleviating the symptoms of RLS/WED.
METHODS
A single-blind study was conducted on individuals with this illness for at least three months. Randomly, 75 patients were assigned into three groups: magnesium, vitamin B6, and placebo. The experimental group received daily doses of 40 mg vitamin B6 or 250 mg magnesium oxide. While others in the control group merely received a placebo. Patients' disease severity and sleep quality were evaluated three times using standard questionnaires (at the beginning of the study, one and two months after therapy). Utilizing SPSS22 software and the ANOVA, t-test, and repeated measure tests, statistical analysis was conducted.
RESULTS
The mean and standard deviation of sleep quality and disease severity at the beginning of the trial and throughout the first month following the intervention did not differ statistically between the three groups. In the second month following the intervention, the mean and standard deviation of sleep quality and disease severity were significantly different (P = 0.001).
CONCLUSION
Taking magnesium and vitamin B6 supplements can reduce the severity of symptoms of RLS/WED patients and improve their sleep quality.

Randomized Controlled Trial
OBJECTIVE
Chronic functional constipation is a frequent condition. The aim of the study was to evaluate the efficacy of the probiotic Lactobacillus (L.) reuteri DSM 17938 and magnesium oxide (MgO) for relieving chronic functional constipation in children.
STUDY DESIGN
A prospective, double-blind, placebo-controlled, randomized, and parallel-group trial was conducted in five pediatric outpatient clinics in Japan. Sixty patients who were more than six months old and under six years of age with a diagnosis of functional constipation according to Rome IV criteria were randomly divided into three groups: group A (n = 20) received L. reuteri DSM 17938 and lactose hydrate as a placebo of MgO; group B (n = 19) received L. reuteri DSM 17938 and MgO; and group C (n = 21) received a placebo of L. reuteri DSM 17938 and MgO.
RESULTS
All three groups exhibited significant improvement in defecation frequency in the fourth week compared with the baseline condition (group A: p < 0.05; group B: p < 0.05; group C: p < 0.05). The MgO group and combination group showed a significant decrease in stool consistency, but the L. reuteri DSM 17938 group did not (group A: p = 0.079; group B: p < 0.05; group C: p < 0.05). MgO significantly suppressed the presence of the genus Dialister. Defecation frequency negatively correlated with the frequency of Clostridiales-belonging bacteria among the gut microbiome.
CONCLUSIONS
L. rueteri DSM 17938 and MgO were both effective in the management of functional constipation in young children. MgO caused an imbalance in the gastrointestinal microbiome, which was not the case in the probiotic group.
