Restrictive versus Liberal Blood Transfusion Strategy in Patients With Acute Myocardial Infarction: A Meta-Analysis of Randomized Clinical Trials.

Background: A meta-analysis of observational studies comparing differences in outcomes between restrictive blood transfusion (RBT) and liberal blood transfusion (LBT) in patients with acute myocardial infarction (AMI) reported that LBT is associated with higher all-cause mortality. Few randomized clinical trials (RCTs) have compared RBT to LBT in patients with AMI and anemia, but no meta-analysis of RCTs was performed to date.

Aim: To assess the clinical effect of RBT compared to LBT in patients with AMI and anemia regarding was all-cause mortality, recurrent MI, revascularization, and heart failure exacerbation.

The effects of curcumin as dietary supplement for patients with COVID-19: A systematic review of randomized clinical trials.

Accumulating evidence has been reported regarding the effect of curcumin as a dietary antiviral on patients with COVID-19; however, findings are controversial. Our systematic review aimed to evaluate the effects of curcumin in patients with COVID-19. Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were systematically searched to identify only randomized clinical trials (RCTs) that assessed curcumin in patients with COVID-19 from inception to September 23, 2021 relevant keywords.

The effects of curcumin as dietary supplement for patients with polycystic ovary syndrome: An updated systematic review and meta-analysis of randomized clinical trials.

This review aims to evaluate if there are clinical benefits of curcumin (CUR) in patients with polycystic ovary syndrome (PCOS). Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were systematically searched to identify only randomized clinical trials (RCTs) that assessed CUR in patients with PCOS from inception to May 5, 2021. Five RCTs were included with a total of 296 patients, with 148 among the CUR groups and 148 patients among the control group.
