The beneficial effects of cinnamon among patients with metabolic diseases: A systematic review and dose-response meta-analysis of randomized-controlled trials.

This systematic review and meta-analysis aims to summarize and conclude the clinical evidence regarding the use of cinnamon among patients with metabolic diseases. A comprehensive literature search without any limitation on language was conducted using the following bibliographical databases: ISI Web of Science, Embase, Scopus, PubMed, and Google Scholar. Search was conducted up to 23 January 2020. A total of 35 clinical trials were included for final analysis. Pooling of results showed a significant reducing effect of cinnamon on total cholesterol (TC) (weighted mean difference (WMD) = -11.67 mg/dL; P = 0.010), triglyceride (TG) (WMD = -16.27 mg/dL; P < 0.001), low density lipoprotein-cholesterol (LDL-C) (WMD = -6.36 mg/dL; P < 0.001), serum glucose (WMD = -11.39 mg/dL; P < 0.001), serum insulin (WMD = -1.27 µIU/mL; P = 0.028), and waist circumstance (WC) (WMD = -1.68 cm; P = 0.016). These lowering effects on TG, TC, LDL-C, and serum glucose levels were robust in studies that used cinnamon supplementation dose ≤1.5 g. Also, our findings of the present meta-analysis showed that cinnamon supplementation could have favorable effects on high density lipoprotein-cholesterol (HDL-C, WMD = 1.35; P = 0.038) as well as systolic (WMD = -3.95 mmHg; P = 0.018) and diastolic (WMD = -3.36; P = 0.001) blood pressure among patients with metabolic diseases. The present meta-analysis suggests that cinnamon might exert beneficial effects on various cardiometabolic risk factors among patients with metabolic diseases.

Association of IGF-1 and IGFBP-3 levels with gastric cancer: A systematic review and meta-analysis.

PURPOSE: Many studies have investigated the association between serum IGF-1 and IGFBP levels with gastric cancer (GC), but the results remained inconclusive. In this work, we performed a systematic review and meta-analysis to examine the precise association of serum levels of IGF-1 and IGFBP with GC. METHODS: A comprehensive systematic search was carried out in PubMed/MEDLINE, SCOPUS, Web of Science, and EMBASE databases for (nested) case-control studies that reported the levels of IGF-1 and IGFBP in GC cases and healthy controls, from inception until October 2020. Weighted mean difference (WMD) was calculated for estimating combined effect size. Subgroup analysis was performed to identify the source of heterogeneity among studies. RESULTS: We found eight and five eligible studies (with 1541 participants) which provided data for IGF-1 and IGFBP, respectively. All studies on IGFBP reported the IGFBP-3 isoform. The pooled results indicate that GC patients had significantly lower serum IGF-1 [WMD = -26.21 ng/mL (95% CI, -45.58 to -6.85; P = .008)] and IGFBP-3 [WMD = -0.41 ng/mL (95% CI, -0.80 to -0.01; P = .04; I2  = 89.9%; P < .001)] levels than those in healthy subjects. Significant heterogeneity was observed in the association, which could be attributed to the sample size of the studies. CONCLUSIONS: In conclusion, our study reveals a significantly lower level of IGF-1 and IGFBP-3 in GC patients compared with healthy control subjects.

Knowledge and attitude about emergency contraception among Saudi women of childbearing age.

CONTEXT: Emergency contraception (EC) use is rare in Saudi Arabia. AIMS: The aim of this study is to determine the knowledge, attitude, and practice of EC among Saudi women of childbearing age. SETTINGS AND DESIGN: This study is a cross-sectional descriptive study using a survey questionnaire tool. MATERIALS AND METHODS: We conducted a survey of married women of childbearing age (18-45 years) attending the Obstetrics and Gynecology Clinic at Riyadh, Saudi Arabia between January and April 2018. STATISTICAL ANALYSIS USED: Pearson's Chi-square test is used for this study. RESULTS: This study included 370 of 525 (70.5%) women, with a mean age of 32.3 ± 6.3 years. Of these, 117 (31.6%) knew how to prevent pregnancy after unprotected sex, and 62 knew about EC. Forty-two women (67.7%) thought EC should be widely advertised, and 30 (48.4%) thought it should be made available even without prescription. Forty-seven women (75.8%) said that they were not shy to ask for EC, and 37 (59.7%) claimed that both partners should decide about the use of EC. The most common reason for not using EC was medical concerns (n = 30, 48.4%). Thirty three (53.2%) of the 62 women with knowledge about EC would use it immediately after sex. Knowledge, awareness, and use of EC were significantly correlated with higher monthly income, educated women, having three or more children, and working women. CONCLUSIONS: Among Saudi women, knowledge, awareness, and use of EC remain low, although a positive attitude for future use of EC exists. Health information campaigns are necessary to reach women, particularly those of low socioeconomic status, less educated women, and housewives to explain EC, its availability, and its proper use.
