Metabolic syndrome - Evidence-based strategies for patient optimization.

With the increasing prevalence of obesity worldwide, it is inevitable that anesthesiologists will encounter patients with metabolic syndrome. Metabolic syndrome encompasses multiple diseases, which include central obesity, hypertension, dyslipidemia, and hyperglycemia. Given the involvement of multiple diseases, metabolic syndrome involves numerous complex pathophysiological processes that negatively impact several organ systems.

Cardiac biomarkers of disordered eating: A case for decreased mean R wave amplitude.

The purpose of this study was to identify cardiac biomarkers of disordered eating. Mean R wave amplitude (mV), mean T wave amplitude (mV), QRS interval (sec), QTc interval (sec), and Tpeak-Tend interval (sec) were assessed via electrocardiography among women with clinical (n = 53) and subclinical (n = 56) eating disorder symptoms versus asymptomatic controls (n = 32). QRS and QTc intervals were significantly longer and mean T and R wave amplitudes significantly lower among women with clinical symptoms compared to asymptomatic controls.

Dissonance-based eating disorder program reduces cardiac risk: A preliminary trial.

Objective: We conducted a randomized, controlled preliminary trial to examine the effect of a dissonance-based eating disorder program on eating disorder symptoms and cardiac risk indices in a community sample of women with subclinical and clinical symptoms (N = 47), examining the efficacy of the program in both the indicated prevention and treatment realms.

Method: Eating disorder symptoms, body mass index, and biomarkers of cardiac risk were examined in dissonance and assessment-only control conditions at baseline, postintervention, and 2-month follow-up. Specifically, we assessed mean R wave amplitude, QT interval length, vagal tone (high frequency spectral power of heart rate variability), and sympathetic tone (low/high frequency spectral power ratio) via electocardiography (ECG) at each assessment period.
