Review
One of the leading global public-health burdens is metabolic syndrome (MetS), despite the many advances in pharmacotherapies. MetS, now known as "developmental origins of health and disease" (DOHaD), can have its origins in early life. Offspring MetS can be programmed by various adverse early-life conditions, such as nutrition imbalance, maternal conditions or diseases, maternal chemical exposure, and medication use. Conversely, early interventions have shown potential to revoke programming processes to prevent MetS of developmental origins, namely reprogramming. In this review, we summarize what is currently known about adverse environmental insults implicated in MetS of developmental origins, including the fundamental underlying mechanisms. We also describe animal models that have been developed to study the developmental programming of MetS. This review extends previous research reviews by addressing implementation of reprogramming strategies to prevent the programming of MetS. These mechanism-targeted strategies include antioxidants, melatonin, resveratrol, probiotics/prebiotics, and amino acids. Much work remains to be accomplished to determine the insults that could induce MetS, to identify the mechanisms behind MetS programming, and to develop potential reprogramming strategies for clinical translation.

Review
The metabolic syndrome is prevalent in developed nations and accounts for the largest burden of non-communicable diseases worldwide. The metabolic syndrome has direct effects on health and increases the risk of developing cancer. Lifestyle factors that are known to promote the metabolic syndrome generally cause pro-inflammatory alterations in microbiota communities in the intestine. Indeed, alterations to the structure and function of intestinal microbiota are sufficient to promote the metabolic syndrome, inflammation and cancer. Among the lifestyle factors that are associated with the metabolic syndrome, disruption of the circadian system, known as circadian dysrhythmia, is increasingly common. Disruption of the circadian system can alter microbiome communities and can perturb host metabolism, energy homeostasis and inflammatory pathways, which leads to the metabolic syndrome. This Perspective discusses the role of intestinal microbiota and microbial metabolites in mediating the effects of disruption of circadian rhythms on human health.

Review
Psoriasis is an immune-mediated systemic disease with associated comorbidities, including metabolic syndrome (MetS) which contributes substantially to premature mortality in patients with psoriasis. However, the pathological mechanisms underlying this comorbidity are unclear. Studies have shown that the pathological parameters of psoriasis mediate the development of MetS. We reviewed the potential mechanisms which mediate the association between psoriasis and MetS, including endoplasmic reticulum stress, pro-inflammatory cytokine releases, excess production of reactive oxygen species, alterations in adipocytokine levels and gut microbiota dysbiosis. Here, we highlight important research questions regarding this association and offer insights into MetS research and treatment.

Observational studies suggested a bidirectional correlation between depression and metabolic syndrome (MetS) and its components. However, the causal associations between them remained unclear. We aimed to investigate whether genetically predicted depression is related to the risk of MetS and its components, and vice versa. We performed a bidirectional two-sample Mendelian randomization (MR) study using summary-level data from the most comprehensive genome-wide association studies (GWAS) of depression (n = 2,113,907), MetS (n = 291,107), waist circumference (n = 462,166), hypertension (n = 463,010) fasting blood glucose (FBG, n = 281,416), triglycerides (n = 441,016), high-density lipoprotein cholesterol (HDL-C, n = 403,943). The random-effects inverse-variance weighted (IVW) method was applied as the primary method. The results identified that genetically predicted depression was significantly positive associated with risk of MetS (OR: 1.224, 95% CI: 1.091-1.374, p = 5.58 × 10), waist circumference (OR: 1.083, 95% CI: 1.027-1.143, p = 0.003), hypertension (OR: 1.028, 95% CI: 1.016-1.039, p = 1.34 × 10) and triglycerides (OR: 1.111, 95% CI: 1.060-1.163, p = 9.35 × 10) while negative associated with HDL-C (OR: 0.932, 95% CI: 0.885-0.981, p = 0.007) but not FBG (OR: 1.010, 95% CI: 0.986-1.034, p = 1.34). No causal relationships were identified for MetS and its components on depression risk. The present MR analysis strength the evidence that depression is a risk factor for MetS and its components (waist circumference, hypertension, FBG, triglycerides, and HDL-C). Early diagnosis and prevention of depression are crucial in the management of MetS and its components.

BACKGROUND
Immune system dysregulation plays a critical role in aortic valve calcification (AVC) and metabolic syndrome (MS) pathogenesis. The study aimed to identify pivotal diagnostic candidate genes for AVC patients with MS.
METHODS
We obtained three AVC and one MS dataset from the gene expression omnibus (GEO) database. Identification of differentially expressed genes (DEGs) and module gene Limma and weighted gene co-expression network analysis (WGCNA), functional enrichment analysis, protein-protein interaction (PPI) network construction, and machine learning algorithms (least absolute shrinkage and selection operator (LASSO) regression and random forest) were used to identify candidate immune-associated hub genes for diagnosing AVC with MS. To assess the diagnostic value, the nomogram and receiver operating characteristic (ROC) curve were developed. Finally, immune cell infiltration was created to investigate immune cell dysregulation in AVC.
RESULTS
The merged AVC dataset included 587 DEGs, and 1,438 module genes were screened out in MS. MS DEGs were primarily enriched in immune regulation. The intersection of DEGs for AVC and module genes for MS was 50, which were mainly enriched in the immune system as well. Following the development of the PPI network, 26 node genes were filtered, and five candidate hub genes were chosen for nomogram building and diagnostic value evaluation after machine learning. The nomogram and all five candidate hub genes had high diagnostic values (area under the curve from 0.732 to 0.982). Various dysregulated immune cells were observed as well.
CONCLUSION
Five immune-associated candidate hub genes (, , , , and ) were identified, and the nomogram was constructed for AVC with MS diagnosis. Our study could provide potential peripheral blood diagnostic candidate genes for AVC in MS patients.

Review
Metabolic syndrome is a cluster of metabolic indicators that increase the risk of diabetes and cardiovascular diseases. Visceral obesity and factors derived from altered adipose tissue, adipokines, play critical roles in the development of metabolic syndrome. Although the adipokines leptin and adiponectin improve insulin sensitivity, others contribute to the development of glucose intolerance, including visfatin, fetuin-A, resistin, and plasminogen activator inhibitor-1 (PAI-1). Leptin and adiponectin increase fatty acid oxidation, prevent foam cell formation, and improve lipid metabolism, while visfatin, fetuin-A, PAI-1, and resistin have pro-atherogenic properties. In this review, we briefly summarize the role of various adipokines in the development of metabolic syndrome, focusing on glucose homeostasis and lipid metabolism.

Review
Metabolic syndrome, also as known as Syndrome X or Insulin Resistance Syndrome, is a complex health problem featuring visceral obesity (the main diagnostic criterion), insulin resistance, dyslipidemia and high blood pressure. Currently, this health condition has gained a momentum globally while raising concerns among health-related communities. The World Health Organization, American Heart Association and International Diabetes Federation have formulated diagnostic criteria for metabolic syndrome. Diet and nutrition can influence this syndrome: for example, the Western diet is associated with increased risk of metabolic syndrome, whereas the Nordic and Mediterranean diets and the Dietary Approach to Stop Hypertension are potentially beneficial. The Mediterranean diet can affect the components of metabolic syndrome due to its high dietary fiber, omega 3 and 9 fatty acids, complex carbohydrates, antioxidants, minerals, vitamins and bioactive substances, such as polyphenols. These nutrients and bioactive substances can combat obesity, dyslipidemia, hypertension and diabetes mellitus. The mechanisms by which they do so are generally related to oxidative stress, inflammation (the most common risk factors for metabolic syndrome) and gastrointestinal function. The literature also shows examples of positive effects of the Mediterranean diet on the metabolic syndrome. In this review of the literature, we shed light on the effects, mechanisms and dynamic relationship between the Mediterranean diet and metabolic syndrome.

Meta-Analysis
This study examines the effects of aerobic, resistance, and combined exercise on metabolic syndrome parameters and cardiovascular risk factors, to identify the most effective way of improving metabolic syndrome and preventing cardiovascular disease. We searched EMBASE, the Cochrane Library, PubMed, MEDLINE, Ovid, the Chinese Biological Medicine Database (CBM), the Wanfang Database, the China National Knowledge Infrastructure (CNKI) database, and the Chinese Scientific Journal Database (VIP), for randomized controlled trials (RCTs), identifying 15 comparing the effects of aerobic, resistance, and combined exercise on metabolic syndrome parameters and cardiovascular risk factors (e.g., glucose, triglyceride, blood pressure, body mass index, etc.). We assessed the quality of the articles and performed a network meta-analysis with a Bayesian random effects model to synthesize direct and indirect evidence. Combined exercise was most effective at controlling glucose and total triglyceride (TG) levels. Aerobic, resistance, and combined exercise groups achieved significant effects regarding body fat. Aerobic exercise was superior to resistance exercise regarding body mass index (BMI). There was no statistically significant difference in weight, waist circumference (WC), levels of high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), insulin, systolic blood pressure (SBP), and diastolic blood pressure (DBP) among the exercise groups. Combined exercise was the best exercise scheme for improving weight, WC, DBP, TG, TC, glucose, and insulin levels. Resistance exercise was most effective at ameliorating body fat, LDL-C levels, and SBP. Aerobic exercise was the optimal way of improving BMI and HDL-C levels. This network meta-analysis suggests combined exercise is the most effective choice in improving the metabolic syndrome and cardiovascular risk parameters, whereas aerobic exercise reveals the minimum effect. Further studies should certify the role resistance exercises play in metabolic syndrome and cardiac rehabilitation.

Review
Although polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women, its etiology is not entirely understood. Clinical symptoms of PCOS include acne, amenorrhea or oligomenorrhea, hirsutism, infertility, and mood disorders, which tend to be the primary focus of clinical management. However, the impact of PCOS on future cardiovascular disease (CVD) risk should not be overlooked, and opportunities to implement CVD prevention strategies in these women should be given high priority. The pathogenesis of PCOS commonly involves insulin resistance which leads to several cardiometabolic abnormalities (e.g., dyslipidemia, hypertension, glucose intolerance, diabetes, and metabolic syndrome), thereby putting women at an increased risk for CVD. Prior studies have found that subclinical CVD markers such as coronary artery calcium scores, C-reactive protein, carotid intima-media thickness, and endothelial dysfunction are more likely to be increased in women with PCOS. While the associations between PCOS and cardiometabolic abnormalities have been well established, whether PCOS is associated with subclinical and clinical CVD, independently of these CVD risk factors, is not entirely clear. Lifestyle interventions and weight management may mitigate some of these future CVD risks and should be encouraged. This review summarizes the literature on PCOS and CVD risk factors and provides recommendations that would aid clinicians in the management of these risk factors.
