DICER is a key enzyme in microRNA (miRNA) biogenesis. Here we show that aerobic exercise training up-regulates DICER in adipose tissue of mice and humans. This can be mimicked by infusion of serum from exercised mice into sedentary mice and depends on AMPK-mediated signaling in both muscle and adipocytes. Adipocyte DICER is required for whole-body… Continue reading Dynamic changes in DICER levels in #adipose tissue control metabolic adaptations to #exercise

Elevated #Coronary Artery Calcium scores are associated with #tooth loss
This study explores the association between Coronary Artery Calcium (CAC) scores and dental pathology such as missing teeth, the (peri-apical) health status and restoration grade of the teeth, and the grade of alveolar bone loss seen on a dental panoramic radiograph (Orthopantomograph–OPG).. ..212 patients were included. We found a statistically significant association between the number… Continue reading Elevated #Coronary Artery Calcium scores are associated with #tooth loss
Association Between #Depressive Symptoms and Incident #Cardiovascular Diseases
It is uncertain whether depressive symptoms are independently associated with subsequent risk of cardiovascular diseases (CVDs).. ..Primary outcomes were incident fatal or nonfatal coronary heart disease (CHD), stroke, and CVD (composite of the 2). Hazard ratios (HRs) per 1-SD higher log CES-D or PHQ-2 adjusted for age, sex, smoking, and diabetes were reported. Results Among… Continue reading Association Between #Depressive Symptoms and Incident #Cardiovascular Diseases
#Lipoprotein (a) and the risk of elevated #depressive symptoms: The Multi-Ethnic Study of Atherosclerosis
Previous studies suggested a potential relationship between plasma lipoprotein (a) [Lp(a)] and elevated depressive symptoms. We aimed to investigate any such relationship in the Multi-Ethnic Study of Atherosclerosis participants who were free of cardiovascular events. Analysis included 4938 participants without elevated depressive symptoms and with Lp(a) levels measured at baseline. Participants were examined at four… Continue reading #Lipoprotein (a) and the risk of elevated #depressive symptoms: The Multi-Ethnic Study of Atherosclerosis
Association between circulating #vascular-related microRNAs and an increase in blood #pressure: a 5-year longitudinal population-based study
MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression and play essential roles in the pathogenesis of cardiovascular disease. Previous cross-sectional studies showed that the levels of several circulating miRNA are associated with hypertension, but there are no prospective longitudinal studies using a general population. The aim of this study is to evaluate the… Continue reading Association between circulating #vascular-related microRNAs and an increase in blood #pressure: a 5-year longitudinal population-based study
#EPA and #DHA differentially modulate monocyte #inflammatory response in subjects with chronic inflammation in part via plasma specialized pro-resolving lipid mediators: A randomized, double-blind, crossover study
The independent effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on chronic inflammation through their downstream lipid mediators, including the specialized pro-resolving lipid mediators (SPM), remain unstudied. Therefore, we compared the effects of EPA and DHA supplementation on monocyte inflammatory response and plasma polyunsaturated fatty acids (PUFA) SPM lipidome.. After a 4-week lead-in phase… Continue reading #EPA and #DHA differentially modulate monocyte #inflammatory response in subjects with chronic inflammation in part via plasma specialized pro-resolving lipid mediators: A randomized, double-blind, crossover study
#Menopause Transition and #Cardiovascular Disease Risk: Implications for Timing of Early Prevention: A Scientific Statement From the American Heart Association
Cardiovascular disease (CVD) is the leading cause of death in women, who have a notable increase in the risk for this disease after menopause and typically develop coronary heart disease several years later than men. This observation led to the hypothesis that the menopause transition (MT) contributes to the increase in coronary heart disease risk.… Continue reading #Menopause Transition and #Cardiovascular Disease Risk: Implications for Timing of Early Prevention: A Scientific Statement From the American Heart Association
Association of #Sedentary Time and Incident Heart #Failure Hospitalization in Postmenopausal Women
Background: The 2018 US Physical Activity Guidelines recommend reducing sedentary behavior (SB) for cardiovascular health. SB’s role in heart failure (HF) is unclear. Methods: We studied 80 982 women in the Women’s Health Initiative Observational Study, aged 50 to 79 years, who were without known HF and reported ability to walk ≥1 block unassisted at… Continue reading Association of #Sedentary Time and Incident Heart #Failure Hospitalization in Postmenopausal Women
#Walking Volume and Speed Are Inversely Associated With Incidence of Treated #Hypertension in #Postmenopausal Women
Few studies have evaluated hypertension incidence in relation to walking, which is a common physical activity among adults. We examined the association between walking and hypertension incidence in 83 435 postmenopausal women who at baseline were aged 50 to 79 years, without known hypertension, heart failure, coronary heart disease, or stroke, and reported the ability to… Continue reading #Walking Volume and Speed Are Inversely Associated With Incidence of Treated #Hypertension in #Postmenopausal Women
