(saffron) and crocin in the treatment of patients with type-2 diabetes mellitus: A systematic review and meta-analysis. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117255. [PMID: 37778521 DOI: 10.1016/j.jep.2023.117255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 08/30/2023] [Accepted: 09/28/2023] [Indexed: 10/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Crocus sativus L. (saffron, Iridaceae) has been traditionally used for thousands of years as herbal medicine for many diseases, including type-2 diabetes mellitus (T2DM), especially in Sri Lanka. Systematic reviews and meta-analysis on C. sativus for T2DM value traditional knowledge about this species. AIM OF THE STUDY To assess the effectiveness of C. sativus powdered plant, hydroethanolic extract and crocin in reducing fasting blood sugar (FBG), glycated hemoglobin (HbA1c), blood pressure, and other metabolic parameters in patients with T2DM. MATERIAL AND METHODS Systematic review and meta-analysis based on searches in PubMed, Embase, and Cochrane, including all randomized clinical trials (RCTs) published before January 2, 2023. Two independent reviewers extracted the data and assessed the risks of bias. The effects of C. sativus and crocin were assessed on glycemic, metabolic, and blood pressure parameters. Weighted (WMD) or standardized (SMD) mean differences (before-after) and 95% confidence intervals (95%CI) of the outcomes were extracted or estimated and meta-analyses were conducted using RevMan 5.4 (Cochrane Collaboration). This protocol was registered in PROSPERO (#CRD42023390073). RESULTS Fifteen of 29 studies were included. Saffron powdered plant decreased AST (WMD -1.19, 95%CI -2.24, -0.13), but increased BMI (WMD 0.56, 95%CI 0.07, 1.05); saffron extract decreased HbA1c (WMD -0.35, 95%CI -0.65, -0.06), FBG (WMD -26.90, 95%CI -38.87, -14.93), creatinine (WMD -0.12, 95%CI -0.19, -0.05), and total cholesterol (WMD -9.29, 95%CI -18.25, -0.33); and crocin decreased HbA1c (WMD -0.43, 95%CI -0.66, -0.20), FBG (WMD -14.10, 95%CI -22.91, -5.30), and systolic blood pressure (WMD -8.18, 95%CI -12.75, -3.61), but increased creatinine levels (WMD 0.24, 95%CI 0.17, 0.32). Of the 15 included studies, 14 had a moderate risk of bias, and one study had a low risk of bias. CONCLUSION C. sativus (saffron) powdered plant, extract, and crocin have potential as an adjunct treatment for T2DM, improving control of metabolic and clinical parameters. However, C. sativus extract seems to be superior because it was effective in more parameters and did not induce adverse effects. Since many studies were at moderate risk of bias, further high-quality research is needed to firmly establish the clinical efficacy of this plant.

Abstract
Previous research has shown that natural medications pose health risks, especially in subjects with comorbidities. This study aimed to evaluate the safety of saffron ethanolic extract (SEE) administration in early and established atherosclerotic rabbits. Rabbits were given a high-cholesterol diet (HCD) for 4 and 8 weeks to induce early and established atherosclerosis respectively, and then they were treated with 50 and 100 mg/kg/day SEE. The body weight of the animals was recorded. Blood samples were collected at baseline, pre-treatment, and post-treatment for hematological studies, lipid profiles, and biochemical profiles. Tissue specimens of the vital organs were subjected to histological examination. The above parameters were significantly altered post-intervention with 4 and 8 weeks of HCD. No significant differences in body weight were observed in all the groups post-treatment with 50 and 100mg/kg of SEE compared to pre-treatment. However, low-density lipoprotein cholesterol, total cholesterol, serum urea, and glucose significantly decreased post-treatment with 50 and 100mg/kg/day SEE compared to pre-treatment in early and established atherosclerosis groups. Hematological parameters that were affected post-intervention with HCD returned to their baseline values post-treatment with 50 and 100mg/kg/day SEE. There was a significant improvement in the vital organs post-treatment with 50 and 100mg/kg SEE. SEE can safely be administered without causing harmful effects on the hematological, biochemical profiles, and vital organs. Notably, SEE exerts hypolipidemic and hypoglycemic effects on atherosclerotic conditions. Further clinical trials are warranted to ensure the safety of saffron administration in patients with atherosclerosis-related diseases.

Pathophysiology of diabetic hepatopathy and molecular mechanisms underlying the hepatoprotective effects of phytochemicals. Biomed Pharmacother 2023; 167:115502. [PMID: 37734266 DOI: 10.1016/j.biopha.2023.115502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 09/05/2023] [Accepted: 09/12/2023] [Indexed: 09/23/2023] Open
Abstract
Patients with diabetes are at risk for liver disorders including glycogen hepatopathy, non-alcoholic fatty liver disease, cirrhosis, and hepatic fibrosis. The pathophysiological mechanisms behind diabetic hepatopathy are complex, some of them include fatty acid accumulation, increased reactive oxygen species, increased advanced glycation end-products, hyperactivity of polyol pathways, increased apoptosis and necrosis, and promotion of fibrosis. A growing number of studies have shown that herbal extracts and their active phytochemicals have antihyperglycemic properties and beneficial effects on diabetic complications. The current review, for the first time, focused on herbal agents that showed beneficial effects on diabetic hepatopathy. For example, animal studies have shown that Moringa oleifera and Morus alba improve liver function in both type-1 and type-2 diabetes. Also, evidence from clinical trials suggests that Boswellia serrata, Juglans regia, Melissa officinalis, Portulaca oleracea, Silybum marianum, Talapotaka Churna, and Urtica dioica reduce serum liver enzymes in diabetic patients. The main active ingredient of these plants to protect the liver seems to be phenolic compounds such as niazirin, chlorogenic acid, resveratrol, etc. Mechanisms responsible for the hepatoprotective activity of herbal agents include improving glucose metabolism, restoring adipokines levels, antioxidant defense, and anti-inflammatory activity. Several signaling pathways are involved in hepatoprotective effects of herbal agents in diabetes, such as phosphoinositide 3-kinase, adenosine monophosphate-activated protein kinase, mitogen-activated protein kinase, and c-Jun NH2-terminal kinase.

Abstract
BACKGROUND AND AIMS Dyslipidemia is one of the most important risk factors of cardiovascular diseases (CVDs). Despite developments in pharmacological treatments for dyslipidemia there are several challenges. Recently some herbs highly considered to control dyslipidemia due to their low toxicity and high potency. In this study we investigated the effects of saffron petals on the lipid profile of dyslipidemia patients as well as several other biochemical blood factors. METHODS In this double blind, placebo controlled, clinical trial, we used systematic random sampling to divide 40 patients with at least two abnormalities in the following factors: (high-density lipoproteins (HDL) ≤40, low-density lipoproteins (LDL) ≥130, triglycerides (TG) ≥200, total cholesterol (Cho) ≥200), into 2 groups of 21 ones. At the end of the intervention period, serum lipid factors, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), urea, creatinin (CR) and fasting blood sugar (FBS) were measured and statistically compared with their values just before the intervention. RESULTS We found that the saffron petal pills markedly (P < 0.001) decreased the serum lipid levels of patients (TG, Cho and LDL) in the intervention group (113.81 ± 12.93, 56.52 ± 4.68 and 48.28 ± 3.70) as compared to the placebo group (18.42 ± 15.79, 4.57 ± 4.40 and 7.38 ± 3.54). Also, comparing the mean value of differences in two groups before and after the intervention showed significant reduction in TG (113.81 ± 26), Cho (56.53 ± 0.30) and LDL (48.28 ± 4.30) levels (P < 0.001). CONCLUSIONS The saffron petal pills considerably reduced blood serum lipid profile and as well as urea and CR of dyslipidemia patients. So, this plant may be used as a potent phytomedicine for treatment and prevention of dyslipidemia and cardiovascular disorders. However, the results indicated that no statistical change was observed in the level of other biochemical blood factors such as ALT, AST, ALP and FBS.

The effect of saffron (Crocus sativus L.) on glycemia, lipid profile, and antioxidant status in patients with type-2 diabetes mellitus: A randomized placebo-controlled trial. Phytother Res 2023; 37:388-398. [PMID: 36580575 DOI: 10.1002/ptr.7600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 07/23/2022] [Accepted: 08/09/2022] [Indexed: 12/30/2022]
Abstract
In the current study, we aimed to investigate the effect of saffron supplementation on glycemic status, lipid profile, atherogenic indices, and oxidative status in patients with type-2 diabetes (T2DM). In a randomized, double-blind controlled trial, 70 patients were randomly allocated into two groups (n = 35, each) and received 100 mg/day of saffron or placebo for eight weeks. Dietary intake, weight, body mass index (BMI), waist and hip circumferences (WC and HC), waist to hip ratio (WHR), fasting blood sugar (FBS), hemoglobin A1c (HbA1c), insulin, and Homeostatic model assessment for insulin resistance (HOMA-IR), lipid profile, atherogenic indices, oxidative status, and liver enzymes were determined before and after the intervention. At the end of the eighth week, saffron intervention could significantly reduce FBS (7.57%), lipid profile (except high-density lipoprotein cholesterol [HDL-C]), atherogenic indices, and liver enzymes (p < .05). Moreover, saffron could improve oxidative status (nitric oxide [NO] and malondialdehyde [MDA] reduced by 26.29% and 16.35%, respectively). Catalase (CAT) concentration remained unchanged. Saffron supplementation may alleviate T2DM by improving glycemic status, lipid profile, liver enzymes, and oxidative status. Further investigation is necessary to assess possible side effects and confirm the positive effect of saffron as a complementary therapy in clinical recommendations for T2DM.

Abstract
Cardiovascular disease (CVD) is one of the most common causes of mortality around the world. The aim of this study is to summarize and conclude the clinical evidence regarding the use of Crocus sativus (C. sativus) and its ingredients on cardiovascular risk factors. A systematic search was conducted with PubMed, Web of Science (ISI), and Scopus in the English language from 2015 until September 2021. A fixed-effect or random-effects model were applied to pool standard mean difference (SMD) and its 95 % confidence intervals (CI). Randomized controlled studies that assessed the clinical effects of C. sativus and its ingredients on dietary intake (Energy, Carbohydrate, Protein, and total Fat) in human subjects were included. Seven studies comprising 421 participants were included in the meta-analysis. Pooling of results showed significant effect of saffron on total fat (−0.14; 95% CI: −0.49 to 0.20; I2 = 57.3%) and significant effect of crocin on Energy (0.94; 95% CI: −0.77 to 2.65; I2 = 95.9%), Carbohydrate (0.44; 95% CI: −0.74 to 1.62; I2 = 92.6%), and Protein (−0.04; 95% CI: −0.26 to 0.34; I2 = 0.0%). Present meta-analysis suggests that treatment with crocins is more effective than saffron in energy, carbohydrate, and protein, while saffron is more effective than crocins in fat. However, further studies are needed to confirm these findings.

Abstract
BACKGROUND The present systematic review and meta-analysis of randomized controlled trials (RCTs) aimed at determining the effect of saffron supplementation on renal function. METHODS Electronic databases were searched up to February 2021. The risk of bias in individual studies was assessed using the Cochrane Collaboration tool. The overall weighted mean difference (WMD) and their 95% confidence intervals (CIs) were calculated using random-effect models. P < 0.05 was considered statistically significant. RESULTS A total of 11 trials were included in this study. Saffron had beneficial effect on BUN (WMD = -0.69 mg/dl; 95% CI, -1.36 to -0.01; P=0.046) compared to placebo, with significant heterogeneity (I 2 = 49.6%, P=0.037). However, it had no significant effect on serum Cr (WMD = 0.04 mg/dl; 95% CI: -0.01 to 0.09; P=0.127). CONCLUSION It seems that saffron supplementation had no significant effect on Cr as a renal function factor. However, BUN reduction was significant in the saffron group compared to placebo.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saffron, the dried red stigma of the perennial herb Crocus sativus L. (Iridaceae), is one of the most important and expensive spices in the world. It is used as a traditional Chinese medicine with demonstrated effects in promoting blood circulation and suppressing blood stasis, cooling blood detoxification, and relieving depression. It is mainly used for the treatment of depression, irregular menstruation, postpartum thrombosis, and bruises. AIM OF THE STUDY This review aims to provide a systematic and up-to-date overview of the phytochemistry, pharmacology, and clinical applications of saffron. We hope it could provide useful references and guidance for the future directions of research on saffron. MATERIALS AND METHODS The online database, such as Web of Science, Google Scholar, Science Direct, PubMed, SpringerLink, Wiley Online Library, SciFinder and Chemical book, and CNKI were used to collect relevant literature. And the classic books about Chinese herbal medicine were also being referenced. RESULTS More than 150 chemical compounds, including carotenoids, flavonoids and flavonoid glycosides, monoterpenes and monoterpenoid derivatives, monocyclic aromatic hydrocarbons, amino acids, alkaloids and others, were revealed. The pharmacological activities study of saffron were focused on the antioxidant, anti-inflammatory, antitumor, antidepressant, hypoglycemic, hypolipidemic, memory-enhancing, and so on. Currently, saffron is mainly used for the treatment of diabetes, Alzheimer's disease, depression, anxiety disorders, cardiovascular diseases, learning and memory disorders, cancer, and other conditions. CONCLUSIONS Phytochemical and pharmacological analyses of saffron have been revealed in recent studies. However, clinical studies have focused mainly on AD, depression and anxiety disorders. Therefore, a large number of clinical trials are needed to study the efficacy of saffron and its major chemical components against other diseases including hypertension, hyperlipidemia, and cancer. Further studies of the mechanism of action and toxicological properties of saffron are also required, especially research to establish an effective dose of saffron and its long-term toxicity in vivo.

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.

[PMID: 34532906 DOI: 10.1002/ptr.7286] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 08/28/2021] [Accepted: 09/02/2021] [Indexed: 12/26/2022]
Abstract
Crocus sativus Linn. (Saffron) is valued worldwide for its potential use in the management of various degenerative disorders, including cardiovascular diseases (CVDs), diabetes, cancer, metabolic syndrome (MetS), neurodegenerative diseases, immune disorders, and sexual dysfunction. Previous reports, based on clinical trials, suggest that crocetin, crocin, picrocrocin, and safranal are the main bioactive components of saffron with antioxidant, anti-inflammatory, and anti-apoptotic effects. In this comprehensive narrative review, we studied the recent clinical trials, investigating the medicinal applications of saffron and/or its components. The present results can provide important insights into the potential of saffron in preventing and treating different disorders, with a special focus on the underlying cellular and molecular mechanisms. However, further high-quality studies are needed to firmly establish the clinical efficacy of saffron in treating some degenerative diseases.

Saffron improves life and sleep quality, glycaemic status, lipid profile and liver function in diabetic patients: A double-blind, placebo-controlled, randomised clinical trial. Int J Clin Pract 2021; 75:e14334.

Abstract
BACKGROUND Type 2 diabetes (T2D) is a metabolic disorder that is related to hyperglycaemia, hyperlipidaemia and liver dysfunction and has detrimental effects on a patient's mental health. Hence, the current study investigated the effects of saffron supplementation on dietary intake, anthropometric measures, mood, sleep quality and metabolic biomarkers in overweight/obese patients with T2D. METHODS In a double-blind, randomised controlled trial, 70 overweight/obese patients with T2D were randomly allocated to two groups and received 100 mg/day saffron or placebo for 8 weeks. Participants completed the Beck depression inventory-II (BDI-II), Hurlbert index of sexual desire (HISD), Pittsburgh Sleep Quality Index (PSQI) and Diabetes-specific Quality-of-Life Brief Clinical Inventory questionnaires (DQOL-BCI). Dietary intake, anthropometric measures, fasting plasma glucose (FPG), haemoglobin A1C (HbA1C), insulin, lipid profile and liver enzymes were determined at baseline and the end of the study. RESULTS At the end of the eighth week, saffron supplementation significantly decreased FPG, triglyceride (TG), insulin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (P < .001). Moreover, significant improvements in BDI-II scores and total quality of life were observed in the intervention group (P < .001). The saffron group showed more significant improvements in PSQI scores than the placebo group, such that at the post-intervention analysis, only the saffron group achieved a "good" sleep band. At this relatively high dose, saffron supplementation improved glycaemic status, lipid profile and liver enzyme measures in patients with T2D while also improving sleep and overall quality of life. CONCLUSION Our results indicate that saffron notably reduced hyperglycaemia and hyperlipidaemia and improved liver function in patients with T2D in an 8-week randomised clinical trial. Saffron also significantly improved depression, sleep quality and overall quality of life in diabetic patients. However, further investigation is necessary to confirm whether saffron is an effective complementary therapy for T2D.

Abstract
BACKGROUND AND AIMS The present systematic review and meta-analysis of randomized controlled trials aimed to determine the effects of saffron supplementation on liver function tests among adults. METHODS Electronic databases including PubMed, ISI Web of Science, and Scopus were searched up to January 2021. The risk of bias in individual studies was assessed using the Cochrane Collaboration tool. The overall estimates and their 95% CIs were calculated using random-effects models. Egger's test and Begg's rank-correlation were run to assess the presence of publication bias. p < 0.05 was considered statistically significant. RESULTS A total of 12 trials involving 608 participants were included in this systematic review and meta-analysis. Saffron supplementation had no significant effect on liver function tests including aspartate transaminase (AST) (weighted mean difference [WMD] = 0.23 U/L; 95% CI -2.22 to 2.69; p = 0.851; I2 = 74.0%), alanine aminotransferase (ALT) (WMD = -1.49 U/L; 95% CI -3.84 to 0.86; p = 0.213; I2 = 60.2%), and alkaline phosphatase (ALP) (WMD = -0.70 U/L; 95% CI -11.35 to 9.95; p = 0.898; I2 = 40.8%) compared to placebo. CONCLUSION Based on what was discussed, it seems that saffron supplementation could not improve liver function tests including AST, ALT, and ALP among the adult population. Further clinical trials with larger sample size, longer duration, and higher doses of saffron should be conducted exclusively among patients with liver dysfunction to elucidate the beneficial role of saffron consumption on liver function.

Abstract
Several pharmaceutical and non-pharmaceutical approaches have been suggested to improve liver health. There is a large discrepancy in the effects of saffron supplementation on liver function in adults. To fill this knowledge gap, this systematic review and meta-analysis of randomized controlled trials (RCTs) assess the effects of saffron supplementation on liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP). A systematic search current to August 2020 was performed in PubMed/Medline, Scopus, Web of Science, and Google Scholar using relevant keywords to detect eligible articles. A random-effects model was used to estimate the weighted mean difference (WMD) and 95% confidence (95% CI). Nine eligible trials were included in the final analysis. The pooled analysis revealed that serum ALT concentrations were significantly reduced using saffron compared to placebo (WMD: -2.39 U/L; 95% CI: -4.57 to -0.22; P = 0.03, I2= 87.9%, P < 0.001). However, saffron supplementation did not affect levels of serum AST (WMD: 1.12 U/L; 95% CI: -1.42 to 3.65; P = 0.39) or ALP (WMD: 4.32 U/L; 95% CI: -6.91 to 15.54; P = 0.78). In the dose-response analysis, we did not find a significant dose-response relationship between dosage and duration of saffron supplementation on serum levels of ALT, AST, and ALP. We found that saffron supplementation can reduce ALT serum concentrations without significant effects on other liver function indicators, including AST and ALP. Nevertheless, future large RCTs on diverse populations are needed to understand better the effects of saffron and its constituents on these enzymes.

Abstract
Background: Experimental studies demonstrated a positive effect of administration of Crocus sativus L. (saffron) and its bioactive ingredients on metabolic profile through their antioxidant capacity. Purpose: To determine if the use of saffron in humans is beneficial to patients with diabetes mellitus (DM) or metabolic syndrome (MS). Methods: This systematic review includes 14 randomized control trials that investigated the impact of saffron administration and its bioactive ingredient crocin on the metabolic profile of patients with DM, MS, prediabetes, and coronary artery disease. We documented the following clinical outcomes: fasting blood glucose (FBG), glycated haemoglobin (HbA1c), total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, systolic, and diastolic blood pressure. Results: Eight studies examined the efficacy of saffron in patients with DM, four with the metabolic syndrome, one with prediabetes and one with coronary artery disease. A favorable effect on FBG was observed. The results regarding blood lipids and blood pressure were inconclusive in the current review. Conclusions: According to the available limited evidence, saffron may have a favorable effect on FBG. Many of the studies in the reviewed literature are of poor quality, and more research is needed in this direction to confirm and establish the above findings.

Abstract
BACKGROUND The Mediterranean diet is a healthy eating pattern that protects against the development of Type 2 diabetes mellitus (T2DM), a metabolic disease characterized by elevated blood sugar levels due to pancreatic beta-cell functional impairment and insulin resistance in various tissues. Inspired by the ancient communities, this diet emphasizes eating primarily plant-based foods, including vegetables, legumes, fruits, cereals, and nuts. Importantly, virgin olive oil is used as the principal source of fat. Red meat is consumed in low amounts while wine and fish are consumed moderately. OBJECTIVE Here, we review the most beneficial components of the Mediterranean Diet and tentative mechanisms of action for prevention and/or management of T2DM, based on research conducted within the last decade. METHODS The references over the last five years have been reviewed and they have been selected properly according to inclusion/ exclusion criteria. RESULTS Several bioactive diet components were evaluated to prevent inflammation and cytokine-induced oxidative damage, reduce glucose concentration, carbohydrate absorption and increase insulin sensitivity and related gene expression. CONCLUSION The adherence to a healthy lifestyle, including diet, exercise and habits remains the best approach for the prevention of diabetes as well as frequent check-ups and education. Though diabetes has a strong genetic component, in recent years many reports strongly point to the critical role of lifestyle specific epigenetic modifications in the development of T2DM. It remains to be established how different components of the Mediterranean Diet interact and influence the epigenetic landscape to prevent or treat the disease.

Abstract
Several studies have investigated serum zinc levels in patients with polycystic ovarian syndrome (PCOS), but the results of these studies remain inconclusive. Therefore, to derive a more precise estimation, we conducted a meta-analysis to investigate serum zinc concentrations in women with PCOS in comparison with healthy subjects. Electronic search was performed in PubMed, Scopus, and Google scholar up to April; 4, 2018 without any restriction. Eligible studies that evaluated the levels of zinc status in subjects with PCOS were included. Weighted mean differences (WMDs) with corresponding 95% CIs in serum zinc levels were initially estimated using a random-effects model. Eight studies, measuring circulating zinc levels in 552 PCOS and 464 control subjects, were included. Pooled effect size suggested that serum zinc levels in women with PCOS were not statistically different than their controls (WMD = -4.43 mg/dL; 95% CI = [-10.30, 1.44]; P = 0.139). Exclusion of one study revealed that women with PCOS significantly have lower serum zinc levels compared to healthy controls (WMD: -6.60 mg/dL; 95% CI = [-12.43, -0.76], P = 0.027). Our study indicated that circulating zinc levels in women with PCOS were significantly lower than those in healthy controls when detailed analysis is conducted. Large scale studies are needed to elucidate clear relation between zinc status and etiology of PCOS.

Abstract
OBJECTIVE Saffron as a natural product has long been used to impede and treat different disorders including cardiovascular disease (CVDs). Stigma is the most principal part of saffron. Various compounds such as carotenoids and flavonoids are the essential components of saffron stigma. The health benefits of saffron have been shown in previous studies; however, there is a lack of comprehensive data on the mechanistic aspects of its cardiovascular-health properties. This current comprehensive review focuses on the medicinal applications of saffron, and then the new findings regarding its cardiovascular-health effects and various cellular and molecular mechanisms of action will be debated. METHODS The literature search of MEDLINE, Embase, PubMed, Google Scholar and Cochrane Library was performed for all comparative studies since 2000-2018 with the limitations of the English language. RESULTS The results provided new evidence about antioxidant, anti-inflammatory, anti- atherogenic, anti- apoptotic, anti- hypertensive, and hypolipidemic effects of saffron. Pharmacological effects of saffron are due to a number of ingredients contained within this spice, including safranal, crocetin and crocins. CONCLUSIONS Our study concludes that saffron with wide range of usefulness in medicine may be the potent candidate in the process of new drug production for the treatment of CVDs.

Abstract
OBJECTIVE Depression and anxiety are major health problems throughout the world. Metabolic changes in type 2 diabetes mellitus induces and aggravates mental disorders, such as depression and anxiety. Saffron as a therapeutic herb may attenuate Comorbid Depression- Anxiety (CDA). So, this trial is designed to investigate the effect of saffron alcoholic extract on symptoms of CDA in type 2 diabetic patients. METHODS Fifty-four outpatients suffered from mild to moderate CDA diagnosed by using Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV), were assessed by Hamilton Depression and anxiety measurements, the Pittsburgh Sleep Quality Index (PSQI), and the Satisfaction with Life Scale (SWLS). The participants of this double-blind, placebo-controlled, single center and randomized trial were randomly assigned to intake 30 mg/day saffron or placebo capsules for 8 weeks. RESULTS After the intervention, mild to moderate CDA, anxiety and sleep disturbance, but not depression alone, were relieved significantly in the saffron group (P < 0.05), whereas, the changes were not significant in the placebo group. Anthropometric measures and blood pressure parameters of the patients in either groups did not change significantly (P > 0.05) during the intervention. Moreover, dietary intake and physical activity did not differ during the study in the two groups. Changes in the life satisfaction were not significant. CONCLUSION The results indicate the beneficial effect of saffron on the mild to moderate CDA in type 2 diabetic patients.
