Independent Effects of Body Fat and Inflammatory Markers on Ventricular Geometry, Midwall Function, and Atrial Remodeling

Abstract BackgroundThe effect of body fat distribution on left ventricular (LV) mass and geometry has been recently recognized. However, data regarding circulating inflammatory markers in relation to regional visceral fat deposits, which are metabolically active tissues that can impact cardiac structural remodeling, remain sparse. HypothesisWe hypothesized that obesity has adverse effects on cardiac function and structure. MethodsWe consecutively studied 1071 asymptomatic subjects (age 49.5 ± 10.5 years, 39.4% female) free from significant valvular disorders, chronic lung disease, or renal disease. Echocardiography‐defined cardiac structures and LV geometries including LV mass, mass‐to‐volume ratio, and fractional shortening were all determined. Body fat composition (Tanita‐305 Body‐Fat Analyzer; Tanita Corp., Tokyo, Japan) was obtained and calculated. Multivariate regression models from various models were used to represent the independent association between body fat and echo‐derived ventricular mass and geometries. ResultsIn multivariable analysis, increasing body fat was significantly related to increase in left atrial (LA) and LV diameter, posterior wall thickness, relative wall thickness (RWT), LV mass, mass‐to‐volume ratio, and decreased midwall fractional shortening with or without stress correction (all P

AbstractBackgroundPatient-related risk factors for the development of postoperative pulmonary complications (PPCs) include age  ≥ 60-years, congestive heart failure, hypoalbuminemia and smoking. The effect of obesity is unclear and has not been shown to independently increase the likelihood of PPCs in trauma patients undergoing trauma laparotomy. We hypothesized the likelihood of mortality and PPCs would increase as b ody mass index (BMI) increases in trauma patients undergoing trauma laparotomy.MethodsThe Trauma Quality Improvement Program (2010 –2016) was queried to identify trauma patients ...

CONCLUSIONS: Our findings suggested that ghrelin protected against obesity-induced myocardial injury by regulating the H19/miR-29a/IGF-1 signalling axis, providing further evidence for the clinical application of ghrelin. PMID: 32084395 [PubMed - as supplied by publisher]

g;berg M Abstract BACKGROUND: Incidence rates of cardiomyopathies, which are a common cause of heart failure in young people, have increased during the last decades. An association between body weight in adolescence and future cardiomyopathy among men was recently identified. Whether or not this holds true also for women is unknown. The aim was therefore to determine whether for young women being overweight or obese is associated with a higher risk of developing cardiomyopathy. METHODS: This was a registry-based national prospective cohort study with data collected from the Swedish Medical Birth Register, 198...

Abstract BACKGROUND: Because of the growing prevalence of terminal heart failure on the one hand and organ shortage on the other hand, an optimal care of heart transplant recipients based on the knowledge of potential risk factors not only early, but also in a long-term course after heart transplantation is of great importance. Therefore, the aim of the present study was to identify predisposing factors for late mortality in this patient collective. METHODS: Data from long-term heart transplant patients collected during follow-up visits in the current center were retrospectively analyzed. Clinical, laboratory...

Telomerase gene therapy is considered in some quarters to be a viable treatment for aging. Telomeres are the caps of repeated DNA sequences at the ends of chromosomes. They are an important part of the mechanism limiting the number of times that somatic cells in the body can divide, the Hayflick limit. A little telomere length is lost with each cell division, and short telomeres trigger cellular senescence or programmed cell death, halting replication. Stem cell populations use telomerase to lengthen their telomeres and thus self-renew to provide a continual supply of new somatic daughter cells with long telomeres to repla...

Authors: Meireles MA, Golçalves J, Neves J Abstract INTRODUCTION: Heart failure frequently coexists with several comorbidities. Our aim is to evaluate the prognostic role of various comorbidities in the risk of acute heart failure development. MATERIAL AND METHODS: Comorbidities of patients with acute heart failure were, retrospectively, compared to a control group of patients with chronic heart failure admitted to an Internal Medicine unit in a 2-year period. Logistic regression models were constructed to determine their association with acute heart failure and to develop a comorbidome. ...

In conclusion, the concept of an epigenetic clock is compelling, but caution should be taken in interpreting associations with age acceleration. Association tests of age acceleration should include age as a covariate.

Abstract The current psychopharmacological treatment approaches for major depression focus on monoaminergic interventions, which are ineffective in a large proportion of patients. Globally, treatment-resistant bipolar depression (TRBD) affects up to 33% of depressive patients receiving treatment. Certain needs are still unmet and require new approaches. Many studies are in favor of treatments with ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, even in single use, whose effects emerge in minutes to hours post administration. However, little data are available on ketamine performance in TRBD patients ...

Conclusion: We identified a consistent pattern of factors associated with a higher prevalence of comorbidities and multimorbidity at diagnosis and an increased time-to-surgery among patients with colorectal cancer with multimorbidity in Spain. This pattern may provide insights for further etiological and preventive research and help to identify patients at a higher risk for poorer cancer outcomes and suboptimal treatment.
