Pulmonary Circulation in Obesity, Diabetes, and Metabolic Syndrome.

Pulmonary Circulation in Obesity, Diabetes, and Metabolic Syndrome. Compr Physiol. 2019 Dec 18;10(1):297-316 Authors: Khaing P, Pandit P, Awsare B, Summer R Abstract Obesity, diabetes mellitus, and the metabolic syndrome are important risk factors for the development of cardiovascular disease, with significant impact on human morbidity and mortality. Several decades of research have accumulated considerable knowledge about the mechanisms by which metabolic conditions precipitate systemic cardiovascular diseases. In short, these mechanisms are thought to involve changes in the external environment of vascular cells, which are mediated by the pro-inflammatory effects of adipokines, free fatty acids, and hyperglycemia. Thus, it has been hypothesized that the pulmonary circulation, witnessing similar insults as the systemic circulation, may be equally vulnerable to the development of vascular disease. Accordingly, recent attention has focused on exploring the mechanistic and epidemiological relationships among obesity, type 2 diabetes mellitus, metabolic syndrome, and pulmonary vascular diseases. In this article, we discuss in detail the preclinical evidence showing a modest but perceivable impact of metabolic disorders on the pulmonary circulation. In addition, we review the existing epidemiological studies examining the relationship among cardiovascular risk factors and pulmonary vascular diseases, using the acute respiratory distress syndrome and pulmonary...

Metabolic syndrome (MetS) is a public health problem of great impact and significance. MetS is generally defined as a grouping of abdominal obesity, impaired glucose metabolism, dyslipidemia and hypertension and has an estimated national prevalence of approximately 34% [1,2]. The presence of MetS has been previously found to confer numerous adverse long-term health consequences, including an increased risk for cardiovascular disease, the development of type 2 diabetes mellitus, fatty liver disease and cancer [3 –6].

AbstractCardiovascular diseases (CVD) are one of the leading causes of death worldwide. Testosterone (T) is an important sex hormone that triggers several genomic and non-genomic pathways, leading to improvements of several cardiovascular risk factors and quality of life in men. At the vascular level, the key effect of T is the vasorelaxation. This review discusses the molecular pathways and clinical implications of T in the vascular system. Firstly, the mechanisms involved in the T vasodilator effect will be presented. Then, it will be discussed the association of T with the main risks for CVD, namely metabolic syndrome, ...

The metabolic syndrome (MetS), characterized by a group of cardiovascular disease (CVD) risk factors including truncal obesity, hypertension, deranged lipid profiles, and abnormal glucose metabolism [1], is a significant risk factor for CVD and type 2 diabetes mellitus (T2DM) [2]. The prevalence of obesity in South Africa is exceptionally high, at 11% in men and 41% in women [3], compared to that of the USA, where 31.7% of men and 33.9% of women are obese [4]. The prevalence of MetS in South Africa is increasing due to the high prevalence of obesity and poor dietary habits, which are now also reported in rural areas [5, 6].

AbstractBackgroundSingle anastomosis sleeve ileal (SASI) bypass is a newly introduced bariatric and metabolic procedure. The present multicenter study aimed to evaluate the efficacy of the SASI bypass in the treatment of patients with morbid obesity and the metabolic syndrome.MethodsThis is a retrospective, seven-country, multicenter study on patients with morbid obesity who underwent the SASI bypass. Data regarding patients ’ demographics, body mass index (BMI), percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), and improvement in comorbidities at 12 months postoperatively and postopera...

AbstractBackgroundDipeptidyl peptidase-4 (DPP-4) inhibitors and sodium-glucose co-transporter 2 (SGLT2) inhibitors are widely used antidiabetic drugs. However, to date, no studies have directly compared the effects of these two drugs on the components of the metabolic syndrome in patients with type 2 diabetes mellitus (T2DM).ObjectivesThe Comparison of Canagliflozin vs. Teneligliptin against Basic Metabolic Risks in Patients with T2DM (CANTABILE) study aims to examine whether the DPP-4 inhibitor (teneligliptin) or the SGLT2 inhibitor (canagliflozin) is the more effective drug for reducing metabolic risk factors as a compos...

Publication date: Available online 23 October 2019Source: The Journal of Steroid Biochemistry and Molecular BiologyAuthor(s): Margarida Lorigo, Melissa Mariana, Manuel C. Lemos, Elisa CairraoAbstractTestosterone (T) is the predominant endogenous androgen in the bloodstream. At the vascular level, T presents genomic and non-genomic effects, and both effects may overlap. The genomic actions assume that androgens can freely cross the plasma membrane of target cells and bind to nuclear androgen receptors, inducing gene transcription and protein synthesis. The non-genomic effects have a more rapid onset and may be related to th...

Authors: Andreeva-Gateva PA, Mihaleva ID, Dimova II Abstract Diabetes mellitus and cardiovascular diseases are part of the metabolic syndrome and share similar risk factors, including obesity, arterial hypertension, and dyslipidemia. Atherosclerosis and insulin resistance contribute to the development of the diseases, and subclinical inflammation is observed in both conditions. There are many proofs about the connection between epigenetic factors and different diseases, including diabetes and cardiovascular diseases. Interestingly, recent studies show that at least some anti-diabetic drugs, as well as blockers of t...

The Metabolic Syndrome may be tentatively defined as the clustering of several metabolic risk factors in the same individual. A progressively higher number of children and adolescents is affected by this syndrome worldwide, mainly as a consequence of the constant increase of the prevalence of obesity and sedentary habits. As obesity, the chance that the metabolic syndrome traks into adulthood is high. Moreover, the evidence of an association between the duration of the exposition to metabolic risk factors and morbidity and mortality justifies early treatment and prevention of the metabolic syndrome in both children and ado...

Authors: Gao RY, Hsu BG, Wu DA, Hou JS, Chen MC Abstract Background: Fibroblast growth factor 21 (FGF21) acts as a potent metabolic regulator. Serum FGF21 levels were significantly higher in obesity and type 2 diabetes mellitus (T2DM) populations. The aim of this study was to evaluate the relationship between serum FGF21 levels and metabolic syndrome (MetS) in T2DM patients. Methods: Fasting blood samples were obtained from 126 T2DM patients. MetS and its components were defined according to the diagnostic criteria from the International Diabetes Federation. Serum FGF21 concentrations were measured using a comm...
