RESUMO
Introduction: The role of magnesium supplement to prevent primary and/or secondary kidney stones has not been fully determined. The aim of this study is to evaluate the effects of magnesium supplement in modifying urinary risk factors of recurrent kidney stones
Method: We searched MEDLINE, Scopus, and Google Scholar databases on December 7, 2014 and reference lists of systematic reviews and randomized, controlled trials. Among the initial 282 articles found by our search strategy and hand searching, we found eight English-language studies were eligible for our study
Result: Magnesium supplementation could be beneficial in nephrolithiasis prevention through increasing urinary magnesium, citrate, and calcium while declining urinary oxalate. In pediatric patients, the results were more prominent and could decline urinary oxalate up to 90% of the baseline
Conclusions: Magnesium supplementation could be beneficial, especially with potassium-citrate combination. However, due to the low number of well-designed randomized controlled trials, especially in pediatrics, the conclusions of this study need further confirmation
RESUMO
Introduction: Left ventricular remodeling is a relatively prevalent complication of acute myocardial infarction [AMI], and it is associated with higher rates of medical issues and mortality. Left ventricle ejection fraction [LVEF] and wall motion score index [WMSI] are unable to detect accurately minor lesions following AMI. Global longitudinal strain [GLS], which is obtained through 2D-speckle tracking echocardiography [2D-STE], provides an angle-dependent measurement by which the infarcted area can be assessed as a means of identifying potential dysfunction. The main objective of this study was to evaluate whether GLS could adequately predict LV remodeling in AMI patients
Methods: The MEDLINE database from database inception to May 6th, 2015, was searched for relevant keywords and the reference lists of systematic reviews and eligible studies were also screened. All studies involving patients with their first reported case of AMI were examined for GLS by 2D-STE and were evaluated for LV remodeling at a three-month follow-up point. Four English-language prospective cohort studies were eligible for inclusion in this study
Result: A total of 291 AMI patients [mean age=57.92 years] were investigated across four different studies. The main finding of this study was that the most reliable and consistent measurement for the purposes of predicting LV remodeling in AMI patients is GLS obtained at the time of discharge, especially in STEMI patients
Discussion: In addition to their poor reproducibility, inability to stratify risks, and inter-observer variability, compensatory hyperkinesis of intact myocytes and myocardial stunning after an AMI are among the main reasons why LVEF and WMSI may not be the most effective predictors of LV remodeling in AMI
Conclusion: GLS obtained by 2D-STE at the time of discharge could be used as a reliable predictor of LV remodeling in AMI patients
