Resveratrol enhanced FOXO3 phosphorylation via synergetic activation of SIRT1 and PI3K/Akt signaling to improve the effects of exercise in elderly rat hearts

Exercise training is considered a benefit to heart function, but the benefit in aging hearts remains unknown. Activation of the PI3K-Akt survival pathway and suppression of Fas/FADD/caspase-8 apoptotic signaling by exercise training in hearts from young subjects have been described in our previous studies. However, the mechanisms are still unclear and need to be explored in aging hearts. Thus, 18-month-old rats were used as a model and underwent swimming exercise training, resveratrol treatment (15 mg/kg/day), or exercise training with resveratrol treatment for 1 month. The results showed that heart function in each group improved. AGE (2014) 36:9705

“…3,25,26 There are multiple quantitative modalities for LVEF calculation; however, qualitative estimates of ejection fraction by EP FOCUS correlate well with both quantitative measurements and subjective estimates by cardiologists. 25,27 Qualitative assessment of global ejection is typically categorized as "hyperdynamic" (LVEF > 65%), "normal" (LVEF 50% to 65%), "moderately depressed" (LVEF 30% to 50%), or "severely depressed" (LVEF < 30%). 25,28 Additionally, in cardiac arrest patients, one can recognize "no coordinated myocardial activity" as a likely indicator of futility of further resuscitation.…”

Emergency physician (EP)-performed focused cardiac ultrasound (EP FOCUS) has been increasingly recognized as a crucial tool to help clinicians diagnose and treat potentially life-threatening conditions. The existing literature demonstrates a variety of EP FOCUS applications and protocols; however, EP FOCUS is not taught, practiced, or interpreted consistently between institutions. Drawing on over 12 years of experience in a large-volume, high-acuity academic emergency department, we have developed a protocol for teaching and performing EP FOCUS known as "The 5Es," where each E represents a specific assessment for immediately relevant clinical information. These include pericardial effusion, qualitative left ventricular ejection, ventricular equality, exit (aortic root diameter), and entrance (inferior vena cava diameter and respirophasic variation). Each of these assessments has been well described in the emergency medicine literature and is within the scope of EP-performed echocardiography. This approach provides a reliable and easily recalled framework for assessing, teaching, and communicating EP FOCUS findings that are essential in caring for the patient in the emergency setting.ACADEMIC EMERGENCY MEDICINE 2015;22:583-593 © 2015 by the Society for Academic Emergency Medicine I t has been recognized for more than 25 years that emergency physician (EP)-performed focused cardiac ultrasound (EP FOCUS) is an important skill for the care of patients with potentially life-threatening presentations.1,2 A recent review detailed 16 specific protocols that included cardiac ultrasound (US) as part of the point-of-care US assessment in medical shock. 3The term "focused cardiac ultrasound" has been addressed in some detail (FOCUS, 4 FCU, 5 and FoCUS 6 ). However, this term is not specialty-specific, may include assessments that are not relevant in the acute/emergency setting, and has not included assessment of the thoracic aortic root ("exit"), which may be particularly applicable to acute and emergent presentations. We have found that the proximal thoracic aorta can be reliably assessed, providing vital information about potential aortic pathology in patients presenting with acute symptoms. 7 We thus propose the "5Es" to assess for the presence of a pericardial effusion, left ventricular ejection, ventricular equality, exit (aortic root diameter), and entrance (inferior vena cava [IVC] diameter and respirophasic variation). The 5Es protocol provides an easy-toteach, evidence-based, and standardized approach to EP FOCUS for the rapid identification and management of time-sensitive pathologic conditions.
