Sex differences in metabolic cardiomyopathy

AbstractIn contrast to ischemic cardiomyopathies which are more common in men, women are over-represented in diabetic cardiomyopathies. Diabetes is a risk factor for cardiovascular disease; however, there is a sexual dimorphism in this risk factor: heart disease is five times more common in diabetic women but only two-times more common in diabetic men. Heart failure with preserved ejection fraction, which is associated with metabolic syndrome, is also more prevalent in women. This review will examine potential mechanisms for the sex differences in metabolic cardiomyopathies. Sex differences in metabolism, calcium handling, nitric oxide, and structural proteins will be evaluated. Nitric oxide synthase and PPARα exhibit sex differences and have also been proposed to mediate the development of hypertrophy and heart failure. We focused on a role for these signalling pathways in regulating sex differences in metabolic cardiomyopathies.

CONCLUSIONS: The prevalence of ESI was 0.13 episodes per year. Poor competency of ES care, catheter mobilization, history of catheter-pulling injury, and mechanical stress by waist belt or the protective bag of PD on ES were risk factors for ESI. PMID: 32072873 [PubMed - in process]

Authors: Koch TR, Shope TR Abstract Obesity is a major factor in the worldwide rise in the prevalence of type 2 diabetes mellitus. The obesity "epidemic" will require novel, effective interventions to permit both the prevention and treatment of diabetes caused by obesity. Laparoscopic vertical sleeve gastrectomy is a newer bariatric surgical procedure with a lower risk of complications (compared to Roux-en-Y gastric bypass surgery). Based in part on restriction of daily caloric intake, sleeve gastrectomy has a major role in inducing significant weight loss and weight loss is maintained for at least 10&nbs...

Authors: Ponticelli C, Arnaboldi L, Moroni G, Corsini A Abstract Introduction: Lipid disorders are frequent after kidney transplantation (KT) and KT recipients are considered at high- or very-high cardiovascular risk. Among many concurring factors, a major role is played by immunosuppressants.Areas covered: General measures to manage lipid disorders first include physical activity and diet counseling. Modulating the doses of immunosuppressants also improves dyslipidemia. When lipid-lowering drugs are necessary to control elevated plasma cholesterol and/or triglycerides, statins are the cornerstone for managing hype...

Background: Total hip arthroplasty (THA) is an effective treatment for symptomatic osteoarthritis after failed nonsurgical therapies. Minimizing perioperative complications is critical for faster recovery and shorter hospital stay. The primary aim of this study was to identify predictors of perioperative major complications (MC) and mortality after THA, and to use these predictors to develop a risk scoring system. Methods: The 2006-2016 National Surgical Quality Improvement Program (NSQIP) database was queried for adult patients who underwent primary elective THA performed under general or neuraxial anesthesia. Univar...

Abstract Diabetes mellitus (DM) has become an increasingly common disease with high disability and mortality rates. Diabetes complications are the main cause of diabetes death and about 50% of diabetic patients died from heart disease in developed countries reported by World Health Organization. Diabetic cardiomyopathy (DCM) has been considered as a high incidence and serious complication of DM and plays a key role in the incidence and development of diabetes related heart failure. Metabolism dysregulation is regarded as an important and earlier factor occurred in the pathogenesis of DCM. Insulin resistance, oxida...

In conclusion, FGF21 belongs to a promising class of cytokines that are induced in response to stress and that can be used as a drug, drug target, or through a biomarker, depending on the physio-pathological context. All these findings will become clear when FGF21 will be used as a therapeutic molecule, exploiting the beneficial effects of FGF21 for treating metabolic disease or when it will be blocked to ameliorate disease progression and the onset of disease. Author Contributions CT and MS wrote the manuscript. VR contributed to the discussion. Funding This work was supported from the AFM-Telethon (19524), Italian Mi...

Conclusion Myocardial energy metabolism is a complex process, which consists of a network of biochemical reactions and pathways. The initial stage is energy substrate utilization due to its uptake and metabolism as well as following participation of intermediates in TCA cycle. Then mitochondrial oxidative phosphorylation enables generation of ATP molecules, and finally, the creatine kinase system transports ATP from mitochondria to the sarcomeres. In the light of the foregoing evidence, metabolism of the heart subjected to pressure overload may be disturbed in all of this areas. In spite of differences among humans and an...

Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...
