PeerJ 2025; 13:e19238. [PMID: 40256727 PMCID: PMC12009027 DOI: 10.7717/peerj.19238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2024] [Accepted: 03/10/2025] [Indexed: 04/22/2025] Open
Abstract
Objective To compare the effectiveness of non-pharmacologic interventions in improving weight loss management in overweight patients with polycystic ovary syndrome (PCOS). Methods Five databases, PubMed, Embase, Cochrane, Web of Science and China Knowledge, were searched for this study. The Cochrane risk of bias tool was used to assess the risk of bias of eligible studies. The included randomized controlled trials were subjected to traditional meta-analysis (TMA) and network meta-analysis (NMA), and the cumulative number of surfaces under the ranking curve (SUCRA) was calculated for each intervention to derive the optimal intervention. Results The study ultimately included 29 articles involving 22 different interventions and 1,565 patients. The results of the NMA showed that the optimal intervention for the four outcome measures (body weight, body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR)) was nutritional supplement + low-calorie diet, Taichi, continuous aerobic exercise and Taichi. Conclusion Current evidence suggests that nutritional supplements + hypocaloric diet; Taichi; continuous aerobic exercise have the greatest clinical advantage in weight loss and deserve to be promoted in the clinic. One of the best interventions for both outcome indicators, Taichi, suggests that it may be a common misconception that simply increasing the intensity of exercise is not the only way to lose weight and improve health.

Abstract
Objective To explore the efficacy of probiotics combined with metformin and a calorie-restricted diet in obese patients with polycystic ovary syndrome (PCOS). Methods Clinical data of 141 obese PCOS patients treated in the 73rd Group Army Hospital from June 2021 to December 2023 were retrospectively analyzed. Patients were grouped according to the treatment records: metformin group (n=69), patients treated with metformin and a calorie-restricted diet) and combined group (n=72, patients treated with probiotics combined with metformin and a calorie-restricted diet). Levels of endocrine hormone indicators, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), Fasting blood glucose (FPG), gut microbiota status, and Body mass index (BMI) were compared before and after the treatment in two groups. Results After the treatment, the levels of endocrine hormone indicators, HOMA-IR, and FPG in both groups were significantly reduced compared to pre-treatment levels and were significantly lower in the combined group compared to the metformin group (P<0.05). Abundance of gut microbiota and Shannon Wiener diversity index in both groups significantly increased after the treatment and were markedly higher in the combined group than in the metformin group (P<0.05). Treatment led to a significant reduction in the body mass index (BMI) in all patients (P<0.05). However, post-treatment BMI was comparable in the two groups (P>0.05). Conclusions In obese patients with PCOS, adding probiotics to the metformin and calorie-restricted diet regimen is more effective in regulating hormone levels, improving blood sugar and insulin resistance, regulating gut microbiota status, and reducing BMI than metformin combined with calorie-restricted diet alone.

The Influence of Dietary Patterns on Polycystic Ovary Syndrome Management in Women: A Review of Randomized Controlled Trials with and Without an Isocaloric Dietary Design. Nutrients 2025; 17:674. [PMID: 40005001 PMCID: PMC11858571 DOI: 10.3390/nu17040674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2025] [Revised: 02/12/2025] [Accepted: 02/12/2025] [Indexed: 02/27/2025] Open
Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disorder that causes cardiometabolic and reproductive disorders in women of reproductive age. Women with PCOS are more likely to have obesity, type 2 diabetes mellitus, and cardiovascular disease. There is an inconclusive consensus on which dietary modification could be most effective in PCOS prevention and treatment. This review aimed to examine the effects of diverse dietary patterns on PCOS in women according to randomized controlled trials (RCTs) with and without an isocaloric dietary design. A literature search was performed in the PubMed®®/MEDLINE®® database up to 14 November 2024. A total of 21 RCTs were reviewed after screening the records, including 15 RCTs with a calorie-restricted dietary design and 6 RCTs with a non-calorie-restricted dietary design. This review found beneficial effects of the calorie-restricted Dietary Approaches to Stop Hypertension (DASH) diet on weight loss and glucose control in women with PCOS in four RCTs with an isocaloric dietary design. The calorie-restricted low-glycemic index (GI) diets from three RCTs and high-protein diets from four RCTs with an isocaloric dietary design showed no significant differences in anthropometric parameters, glucose control, lipids, and gonadal parameters compared with the control diet in women with PCOS. Non-calorie-restricted low-carbohydrate diets from four RCTs with an isocaloric dietary design showed similar results to the calorie-restricted low-GI diets and high-protein diets. However, the existing number of RCTs is insufficient to conclude the association between dietary patterns and PCOS in women. Further, well-designed dietary intervention studies are needed to assess the role of dietary patterns in PCOS beyond calorie restriction.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine disorders among reproductive-aged women. It is characterized by hyperandrogenism, anovulation, and polycystic ovaries. Lifestyle changes are suggested as first-line interventions in managing PCOS. This systematic review aims to assess the scientific evidence regarding the role of lifestyle modifications (dietary changes, physical activity, and behavioral changes) in improving reproductive, anthropometric, metabolic, and psychological outcomes in women with PCOS. Dietary interventions such as foods with low glycemic index scores; caloric restrictions; high-fiber, omega three fatty acid-rich diets; ketogenic diets; Mediterranean diets; antioxidant-rich food; and anti-inflammatory diets improve insulin sensitivity and hormonal balance in women with PCOS. Physical activity, like aerobic and resistance exercise, enhances insulin sensitivity, helps weight loss, and improves metabolic and reproductive outcomes in women with PCOS. Further, behavioral and education modules can also be used to improve awareness, adherence, and the effectiveness of conventional treatment and to manage mental health issues related to PCOS. Collectively, lifestyle modifications not only improve the biochemical, hormonal, and anthropometric parameters in PCOS patients but also reduce the long-term risks of metabolic and cardiovascular diseases.

Different supplements improve insulin resistance, hormonal functions, and oxidative stress on overweight and obese women with polycystic ovary syndrome: a systematic review and meta-analysis. Front Endocrinol (Lausanne) 2024; 15:1464959. [PMID: 39722805 PMCID: PMC11668966 DOI: 10.3389/fendo.2024.1464959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2024] [Accepted: 10/16/2024] [Indexed: 12/28/2024] Open
Abstract
Objectives To investigate various supplements that improve insulin resistance, hormonal status, and oxidative stress in overweight or obese women with polycystic ovarian syndrome (PCOS). Methods A literature search was conducted on four different databases, which led to the discovery of twenty - five randomized controlled trials (RCTs). These RCTs evaluated the efficacy of various supplements in improving insulin resistance (IR), hormonal status, and oxidative stress among overweight or obese women diagnosed with PCOS. Subsequently, data extraction and analysis were carried out to determine the quality of the study's methodological design and the potential for bias. Moreover, a meta-analysis was performed using the data from the RCTs. Results A total of 25 RCTs were carried out, and 1636 women were enrolled. All participants were overweight or obese. The standardized mean differences (SMD) were as follows: For fasting plasma glucose (FPG), it was -0.34 (95% confidence interval [CI], -0.49 to -0.19, p = 0.123, I2 = 30.8%); for insulin, it was -0.67 (95% CI, -0.83 to -0.52, p = 0.208, I2 = 24%); for fasting insulin (FI), it was -0.26 (95% CI, -0.52 to -0.00, p = 0.269, I2 = 21.9%); for homeostatic model assessment-insulin resistance index (HOMA-IR), it was -0.59 (95% CI, -0.73 to -0.45, p = 0.015, I2 = 48.7%); for homoeostatic model assessment beta - cell function (HOMA-B), it was -0.51 (95% CI, -0.75 to -0.27, p = 0.547, I2 = 0%); for quantitative insulin sensitivity check index (QUICKI), it was 0.94 (95% CI, 0.76 to -1.12, p = 0.191, I2 = 27.5%); for total testosterone, it was -0.61 (95% CI, -1.14 to -0.09, p = 0.00, I2 = 78.5%); for testosterone, it was -0.38 (95% CI, -0.86 to 0.10, p = 0.03, I2 = 71.5%); for follicle - stimulating hormone (FSH), it was 0.16 (95% CI, -0.08 to 0.40, p = 0.470, I2 = 0%); for luteinizing hormone (LH), it was -0.56 (95% CI, -1.32 to 0.20, p = 0.000, I2 = 91.1%); for sex hormone - binding globulin (SHBG), it was 0.35 (95% CI, 0.02 to 0.69, p = 0.000, I2 = 78%); for dehydroepiandrosterone (DHEAS), it was -0.27 (95% CI, -0.76 to 0.21, p = 0.001, I2 = 78.7%); for plasma total antioxidant capacity (TAC), it was 0.87 (95% CI, 0.45 to 1.30, p = 0.004, I2 = 71.3%); for plasma malondialdehyde (MDA), it was -0.57 (95% CI, -0.79 to -0.36, p = 0.992, I2 = 0.0%). Conclusion This study's findings indicate that, in comparison with a placebo, supplements have a favorable effect on IR, hormonal functions, and oxidative stress in PCOS. Nevertheless, it is crucial to note that the above-drawn conclusions need to be verified by more high-quality studies, given the limitations regarding the number and quality of the included studies.

Abstract
Multiple myeloma (MM) patients are often accompanied by heightened levels of oxidative stress, even following bone marrow transplantation. Trace mineral supplements have been found to regulate and inhibit the activity of oxidative radicals and inflammatory factors, which are involved in the pathogenesis of MM. The study sought to evaluate the effectiveness of the supplementation by analyzing changes in oxidative, anti-oxidative, and inflammation markers. Patients were randomly assigned to a zinc or placebo group, with the former receiving 30 mg of zinc or placebo tablets daily for 1 month. Blood samples were collected from the patients on the day of transplantation, 15 days, and 30 days post-transplantation. Real-time PCR was employed to measure the expression of oxidative/antioxidative genes. Furthermore, the protein level of oxidative markers in serum samples was assessed. Finally, serum TNF-α concentrations were measured using the ELISA technique. The expression levels of SOD1, SOD2, and NRF2 genes were significantly higher on days 15 and 30 compared to the control group (P < 0.05), with a greater increase on day 30 (P < 0.05). Conversely, the expression levels of Keap1 and NOX2 genes were lower on day 30 than those of the control group (P < 0.05), with a further decrease from day 15 to day 30 (P < 0.05). The experimental group exhibited a notable reduction in TNF-α cytokine levels on day 30 compared to the control and placebo groups (P < 0.05). All findings were coordinated according to the nutritional questionnaire. Our findings suggest a potential benefit of zinc supplementation in managing the adverse effects of chemotherapy in MM patients, warranting further investigation.

Abstract
Polycystic ovarian syndrome (PCOS) impacts the health of women worldwide. It is a condition consisting of dysfunctional cystic ovaries resulting in hormonal imbalance. Many women have symptoms such as infertility, increased production of androgens, and insulin resistance. Barriers to effective treatment of PCOS include issues such as delays in diagnosis and inconsistencies in treatment plans among physicians. Despite the current use of available medications to decrease symptomatology, women with PCOS continue to report a decreased quality of life. Using the electronic databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and ScienceDirect, a scoping review was conducted on the globally available treatments for PCOS. After applying pre-determined inclusion criteria, 41 studies were included in this scoping review. The literature on the available treatments for PCOS revealed a wide range of therapeutics with evidence of reduction of symptoms and/or improvement in fertility status and pathological processes such as insulin resistance, hormone imbalance, obesity, inflammation, and infertility. Dozens of treatment options for PCOS have been identified, including new medications and modifications to existing treatment regimens. The hormonal drug Fezolinetant demonstrated effective suppression of hyperandrogenism. Drugs used to treat diabetes, such as Liraglutide, were found effective for weight loss. Green cardamom, cinnamon, and other supplements proved effective in treating metabolic dysfunction. Alternative approaches, such as osteopathic manipulative therapy and acupuncture, decreased sympathetic tone and androgen levels. This review provides a succinct overview of PCOS therapies that can be used by those with PCOS and their physicians everywhere. With a better understanding of their options, women with PCOS can become more involved in the decision-making process to improve their health. More research is needed on novel therapies that aim to reduce the primary pathogenesis of PCOS.

[PMID: 39201076 PMCID: PMC11355208 DOI: 10.3390/jcm13164934] [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: 07/24/2024] [Revised: 08/12/2024] [Accepted: 08/16/2024] [Indexed: 09/02/2024] Open
Abstract
Background: Currently, the primary strategy for addressing polycystic ovarian syndrome (PCOS) involves lifestyle modifications, with a focus on weight loss. The purpose of this meta-analysis was to assess the impact of weight loss through dietary interventions on inflammatory status and hyperandrogenism in PCOS women. Methods: A comprehensive search was conducted to identify randomised controlled trials (RCTs) and cohort studies assessing the impact of diet-induced weight loss on circulating inflammatory markers (CRP, IL-6, IL-1β, TNF-α), androgens (testosterone, androstenedione), SHBG, and luteinising hormone (LH) in PCOS women. The quality and risk of bias of the included studies were assessed using the Cochrane Collaboration's tool for RCTs and the Newcastle-Ottawa Scale for cohort studies. Data were entered into RevMan software v5.9 for the calculation of standard mean difference (SMD) and the 95% confidence interval (95%CI) of circulating inflammatory markers, androgens, and LH between baseline and post-weight loss values. Results: Eleven studies (n = 323) were eligible for the systematic review, of which nine (n = 286) were included in the meta-analysis. Pooled analysis of data revealed a statistically significant decrease in circulating CRP (SMD 0.39, 95%CI 0.22, 0.56; 9 studies, n = 286), IL-6 (SMD 0.37, 95%Cl, 0.12, 0.61; 3 Studies, n = 140), TNF-α (SMD 0.30, 95%Cl, 0.07, 0.53; 4 Studies, n = 162), androstenedione (SMD 0.36, 95%Cl, 0.13, 0.60; 4 studies, n = 147) and LH (SMD 0.30, 95% Cl, 0.09, 0.51; 5 studies, n = 197) after weight loss compared to baseline levels among PCOS women. A meta-analysis of five studies (n = 173) showed a statistically significant increase in circulating SHBG after weight loss compared to baseline levels (SMD -0.43, 95%Cl, -0.65, -0.21). Conclusions: These findings suggest that weight loss induced by dietary interventions seems to improve PCOS-related chronic inflammation and hyperandrogenism. The possible causative relationship between the improvement in inflammation and hyperandrogenism remains to be determined.

Abstract
The bioactive compounds in cardamom have been found to enhance cardiovascular health by improving blood lipids and inflammation. We hypothesized that cardamom consumption might ameliorate cardiovascular metabolic biomarkers in adults; however, there is still debate regarding its impact on cardiac metabolism. This research was therefore designed to determine if cardamom consumption had a favorable impact on lipid profiles, inflammatory markers, and oxidative stress indices as they related to cardiovascular diseases. A comprehensive search was conducted through PubMed, Scopus, Embase, Web of Science, and the Cochrane Library on July 4, 2023. Using a random-effects model pooled the weighted mean difference (WMD) and 95% confidence interval (CI). The final 12 trials containing 989 participants were included. The results illustrated that cardamom consumption could improve total cholesterol (WMD = -8.56 mg/dL; 95% CI, -14.90 to -2.22), triglycerides (WMD = -14.09 mg/dL; 95% CI, -24.01 to -4.17), high-sensitivity C-reactive protein (WMD = -1.01 ng/mL; 95% CI, -1.81 to -0.22), and interleukin-6 (WMD = -1.81 pg/mL; 95% CI, -3.06 to -0.56). However, it did not have significant influences on high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and some indicators of oxidative stress. In conclusion, cardamom consumption can improve specific cardiovascular metabolic biomarkers and potentially confer protective effects on cardiovascular health. However, more large-scale clinical research with better designs would further validate the findings, which will offer substantial evidence of cardamom as nutritional and functional products.

Abstract
Ayurveda, an ancient holistic and personalized healing system originating from the Indian subcontinent, has been gaining increasing attention as a complementary and alternative medical practice for treating various health conditions, including those related to women's reproductive well-being. This comprehensive literature review examines a wide array of experimental and clinical studies exploring the diverse facets of Ayurvedic interventions in addressing issues such as menstrual irregularities, polycystic ovary syndrome (PCOS), infertility, and menopausal symptoms. The paper specifically focuses on discussing the available data regarding the efficacy of Tulsi (Ocimum tenuiflorum), ashwagandha (Withania somnifera), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma longa), and Shatavari (Asparagus racemosus), which have traditionally been used in Ayurvedic medicine for centuries. The synthesis of literature not only highlights the potential benefits of these Ayurvedic interventions, but also critically assesses the methodological rigor of existing studies, identifying research gaps, and proposing directions for future investigations. While acknowledging the need for further rigorous research and clinical trials, the review emphasizes the benefits of collaborative and integrative healthcare. This review aims to serve as a valuable resource for healthcare practitioners, researchers, and individuals seeking holistic and natural alternatives for female reproductive health management.

Abstract
Background Dietary interventions, recommended as a primary approach globally, benefit women with polycystic ovary syndrome (PCOS) by inducing weight loss and improving clinical symptoms, metabolism, and pregnancy results. However, the impact of diet on PCOS in individuals with BMI ≥ 25 kg/m2 is unclear. The aim of this review was to offer dietary guidance for these patients. Methods Six databases, CNKI, Wanfang, VIP, PubMed, Cochrane Library, and Web of Science, were searched systematically from inception to December 2023 for clinical randomized controlled trials (RCT) on dietary interventions for PCOS. Two researchers independently screened and extracted data following pre-defined inclusion criteria, with bias assessment using the Cochrane Handbook and Review Manager (version 5.4) software. Results Nine RCTs with 559 participants were included. Among women with PCOS and obesity, compared to the control group, individuals who underwent dietary interventions experienced improvements in weight-related Indicators, glycolipid metabolism, hormone-related indicators, and fertility-related outcomes. Subgroup analysis indicated that calorie-restricted diets (CRDs) and low-energy-low-carb combined diets had advantages over other dietary interventions. Moreover, the overweight period was the optimal intervention period. Conclusions Dietary interventions can improve the clinical manifestations of PCOS and pregnancy rates in patients with a BMI ≥ 25 kg/m2. Particularly, CRDs, low-calorie-low-carb combined diets, and low-calorie-extract combined diets are recommended.

A Scoping Review of the Clinical Evidence for the Health Benefits of Culinary Doses of Herbs and Spices for the Prevention and Treatment of Metabolic Syndrome. Nutrients 2023; 15:4867. [PMID: 38068725 PMCID: PMC10708057 DOI: 10.3390/nu15234867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 11/10/2023] [Accepted: 11/14/2023] [Indexed: 12/18/2023] Open
Abstract
Metabolic syndrome (MetS) is a growing global health problem. Evidence suggests that diets rich in phytochemical-containing herbs and spices can contribute to reducing the risk of chronic diseases. This review assesses the scope of evidence supporting the use of herbs and spices in the diet for the prevention or treatment of MetS and its associated health conditions. A search of the PubMed, Scopus and Google Scholar databases was carried out to assess the available clinical evidence for culinary doses of commonly used herbs and spices. Trials that were measuring health factors related to metabolic disorders in healthy individuals, or the health of individuals with MetS or associated diseases, were included. Out of a total of 1738 papers identified, there were 142 relevant studies on black pepper, chilli, cardamom, cinnamon, coriander, cumin, fennel, fenugreek, garlic, ginger, nigella seed, rosemary, sage and turmeric. No relevant research was found for cloves, mint, oregano, parsley or thyme. Cinnamon, fenugreek and ginger were the herbs/spices with the most published trials on them and that showed promise for glycaemic control. Cardamom appears to have potential to reduce inflammatory markers, and cinnamon, ginger and turmeric to reduce blood lipids. Patients with type 2 diabetes were the population most likely to be included in studies, but the preventative benefits of herbs/spices in healthy populations were also investigated, particularly for chilli, ginger and cinnamon. There is evidence for the beneficial effect of culinary doses of many common herbs/spices in the prevention and treatment of MetS and associated disorders.

Nutrients 2023; 15:2965. [PMID: 37447289 DOI: 10.3390/nu15132965] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 05/28/2023] [Accepted: 05/30/2023] [Indexed: 07/15/2023] Open
Abstract
The chemical profiling of phenolic and terpenoid compounds in whole cardamom, skin, and seeds (Elettaria cardamomum (L.) Maton) showed 11 phenolics and 16 terpenoids, many of which are reported for the first time. Herein, we report the anti-inflammatory properties of a methanolic extract of whole cardamom in colon and macrophage cells stimulated with an inflammatory bacteria lipopolysaccharide (LPS). The results show that cardamom extracts lowered the expression of pro-inflammatory genes NFkβ, TNFα, IL-6, and COX2 in colon cells by reducing reactive oxygen species (ROS) while not affecting LXRα. In macrophages, cardamom extracts lowered the expression of pro-inflammatory genes NFkβ, TNFα, IL-6, and COX2 and decreased NO levels through a reduction in ROS and enhanced gene expression of nuclear receptors LXRα and PPARγ. The cardamom extracts in a range of 200-800 μg/mL did not show toxicity effects in colon or macrophage cells. The whole-cardamom methanolic extracts contained high levels of phenolics compounds (e.g., protocatechuic acid, caffeic acid, syringic acid, and 5-O-caffeoylquinic acid, among others) and are likely responsible for the anti-inflammatory and multifunctional effects observed in this study. The generated information suggests that cardamom may play a protective role against low-grade inflammation that can be the basis of future in vivo studies using mice models of inflammation and associated chronic diseases.

Abstract
An increase in life expectancy leads to a greater impact of chronic non-communicable diseases. This is even more remarkable in elder populations, to whom these become main determinants of health status, affecting mental and physical health, quality of life, and autonomy. Disease appearance is closely related to the levels of cellular oxidation, pointing out the importance of including foods in one's diet that can prevent oxidative stress. Previous studies and clinical data suggest that some plant-based products can slow and reduce the cellular degradation associated with aging and age-related diseases. Many plants from one family present several applications that range from the food to the pharmaceutical industry due to their characteristic flavor and scents. The Zingiberaceae family, which includes cardamom, turmeric, and ginger, has bioactive compounds with antioxidant activities. They also have anti-inflammatory, antimicrobial, anticancer, and antiemetic activities and properties that help prevent cardiovascular and neurodegenerative diseases. These products are abundant sources of chemical substances, such as alkaloids, carbohydrates, proteins, phenolic acids, flavonoids, and diarylheptanoids. The main bioactive compounds found in this family (cardamom, turmeric, and ginger) are 1,8-cineole, α-terpinyl acetate, β-turmerone, and α-zingiberene. The present review gathers evidence surrounding the effects of dietary intake of extracts of the Zingiberaceae family and their underlying mechanisms of action. These extracts could be an adjuvant treatment for oxidative-stress-related pathologies. However, the bioavailability of these compounds needs to be optimized, and further research is needed to determine appropriate concentrations and their antioxidant effects in the body.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is an endocrine disease in which related to obesity, metabolic disorders and is considered as one of the main causes of infertility in women. This trial was investigated the effects of green cardamom on the expression of genes implicated in obesity and diabetes among obese women with PCOS. METHODS One hundred ninety-four PCOS women were randomly divided two groups: intervention (n = 99; 3 g/day green cardamom) and control groups (n = 95). All of them were given low calorie diet. Anthropometric, glycemic and androgen hormones were assessed before and after 16-week intervention. The reverse transcription-polymerase chain reaction (RT-PCR) method was used to measure fat mass and obesity-associated (FTO), peroxisome proliferative activating receptor- (PPAR-), carnitine palmitoyltransferase 1A (CPT1A), acetyl-CoA carboxylase beta (ACAB), leptin receptor (LEPR), ghrelin, and lamin A/C (LAMIN) genes expression in each group. RESULTS Anthropometric indices were significantly decreased after intervention in both two studied groups. Glycemic indices and androgen hormones were significantly improved in the intervention group compared to the control group. The expression levels of FTO, CPT1A, LEPR, and LAMIN were significantly downregulated compared to control group (P < 0.001), as well as, PPAR-y was significantly upregulated in the intervention group after intervention with green cardamom compared to control group (P < 0.001). CONCLUSION This current study showed that the administration of green cardamom is a beneficial approach for improving anthropometric, glycemic, and androgen hormones, as well as obesity and diabetes genes expression in PCOS women under the low-calorie diet. TRIAL REGISTRATION This trial was registered with the Iranian Clinical Trials Registry (registration number: IRCT20200608047697N1). 1 August, 2020; https://www.irct.ir/trial/48748.

Abstract
PURPOSE OF REVIEW Chronic low-grade inflammation may contribute to the onset and progression of communicable and chronic diseases. This review examined the effects and eventual mediation roles of different nutritional factors on inflammation. RECENT FINDINGS Potential nutritional compounds influencing inflammation processes include macro and micronutrients, bioactive molecules (polyphenols), specific food components, and culinary ingredients as well as standardized dietary patterns, eating habits, and chrononutrition features. Therefore, research in this field is still required, taking into account critical aspects of heterogeneity including type of population, minimum and maximum intakes and adverse effects, cooking methods, physiopathological status, and times of intervention. Moreover, the integrative analysis of traditional variables (age, sex, metabolic profile, clinical history, body phenotype, habitual dietary intake, physical activity levels, and lifestyle) together with individualized issues (genetic background, epigenetic signatures, microbiota composition, gene expression profiles, and metabolomic fingerprints) may contribute to the knowledge and prescription of more personalized treatments aimed to improving the precision medical management of inflammation as well as the design of anti-inflammatory diets in chronic and communicable diseases.

Abstract
OBJECTIVE To explore the effects of the quinoa diet on glycolipid metabolism and endoplasmic reticulum (ER) stress in an obese mouse model. METHODS Six-week-old C57BL/6J female mice have received a high-fat diet (HFD) to induce obesity and subsequently were treated with a quinoa diet for 12 weeks. During this period, fasting blood glucose, body fat and insulin resistance were measured regularly. At the end of the experiment, mouse serum and liver tissue were collected. The differences in glucose and lipid metabolism were analyzed, and liver tissue pathological morphology, liver endoplasmic reticulum stress-related mRNA and protein levels, and serum oxidative stress levels were measured. RESULTS Quinoa diet could significantly reduce the level of blood glucose, triglyceride, cholesterol, low-density lipoprotein, improve glucose tolerance, as well as improve histological changes of liver tissues in obese mice (P < 0.05 or < 0.01). Besides, quinoa could improve oxidative stress indicators such as GSH, and MDA (P < 0.05 or < 0.01). Furthermore, quinoa can down-regulate mRNA expression of ER stress markers eIF2α, GRP78, and CHOP in the liver of obese mice (P < 0.05 or < 0.01). CONCLUSIONS Quinoa supplementation can improve glycolipid metabolism, regulate ER stress, and alleviate obesity in HFD-induced mice.
