    Implantable cardioverter-defibrillators, additionally known as ICDs, are battery-powered gadgets positioned under the skin which could detect peculiar heart rhythms and supply an electric shock to restore a regular heartbeat. ICD procedure cost helps reduce the risk of sudden cardiac death and can be recommended for life-threatening rhythm irregularities due to myocardial infarction, cardiac arrest, or congenital heart disease.

    Flat and/or abnormal diurnal cortisol patterns found to be associated with earlier mortality in breast cancer.  The flatter cortisol pattern, the earlier the mortality.  Several points here: this highlights the impact of cortisol on the immune system.  Second, this reveals how much of the research has moved to saliva as the gold standard.  This study by the NCI, used salivary cortisol to evaluate the risk of breast cancer survivors.
