ABSTRACT
BACKGROUND AND AIMS: Possible protective effects of saffron (Crocus sativus L) have been reported in several randomized clinical trials (RCTs). Current systematic review was performed to summarize the efficacy of saffron intake on liver enzymes. METHODS: An electronic database search was conducted on PubMed/Medline, Scopus, Web of Science, and Cochrane for RCTs comparing effect of saffron and placebo on liver enzymes from inception to July 2021. There was no restriction in language of included studies and we calculated the standardized mean difference (SMD) and 95% Confidence Intervals (CI) for each variable. Random-effect model was used to calculate effect size. RESULTS: Eight studies (n = 463 participants) were included in the systematic review. The saffron intake was associated with a statistically significant decrease in aspartate aminotransferase (AST) (SMD: -0.18; 95% CI: -0.34, -0.02; I2 = 0%) in comparison to placebo intake. Our results also indicated that saffron consumption did not have a significant effect on alanine aminotransferase (ALT) (SMD: -0.14; 95% CI: -0.36, 0.09; I2 = 47.0%) and alkaline phosphatase (ALP) levels (SMD: 0.14; 95% CI: -0.18, 0.46; I2 = 42.9%) compared to placebo. CONCLUSIONS: Saffron intake showed beneficial impacts on circulating AST levels. However, larger well-designed RCTs are still needed to clarify the effect of saffron intake on these and other liver enzymes.

OBJECTIVE: The study aims to analyze the effectiveness of bevacizumab in addressing the complications associated with gynecological cancers and evaluates effective treatments for various gynecological cancers. METHODS: The study follows a systematic review approach that has been implemented to analyze the qualitative published data from previous studies. Studies related with the trials of angiogenesis and bevacizumab were selected in the review. RESULTS: In general, the management of gynecological cancers include chemotherapy, surgery and radiation therapy. Results suggest bevacizumab as an effective treatment modality for cervical and several other cancers. Overall, bevacizumab showed promising results in improving the overall survival rate of gynecological cancer patients through the combination of bevacizumab with other chemotherapeutic agents. CONCLUSION: Bevacizumab possess less documented adverse effects when compared to other chemotherapeutic agents. The manifestation and severity of adverse effects reported varied according to the chemotherapeutic agent(s) that were used with bevacizumab in combination therapy. Overall, bevacizumab effectively improved the survival rate in patients with several gynaecological cancers.
