PURPOSE Cortisol awakening response (CAR) and nighttime cortisol levels have been used as indices of adrenocortical activity. However, population-based statistical information regarding these indices has not been provided in healthy subjects. This study was carried out to provide basic statistical information regarding these indices. MATERIALS AND METHODS Cortisol levels were measured in sali...

The cortisol awakening response (CAR) has been widely assessed as a measure of hypothalamic-pituitary-adrenal (HPA) axis activity. Short-term stability is high; however, little is known about the long-term stability of the CAR. Because there are indications that development in adolescence influences HPA axis activity, this study investigated the stability of the CAR over adolescence. Participan...

The current study examined intra-individual relationships between the cortisol awakening response (CAR) and state sleep-related and psychosocial variables in a pooled design study. 12 healthy female participants (age range: 22-41 years.) were examined on 12 study days each, occurring at three-day intervals. Quantitative diaries capturing state sleep-related and psychosocial variables were fille...

INTRODUCTION Given the high morbidity and mortality associated with intracerebral hemorrhage (ICH), family members, and healthcare providers base early supportive management decisions, at least in part, on expected prognosis. In the comatose patient with ICH, this short-term prognosis is most overtly characterized by regaining of consciousness. DESIGN A retrospective consecutive cohort of 51 ...

abstract objective: to investigate the anesthesia-postoperative awakening time (at) of hepatitis- related cirrhosis patients and their relations to grading scores, portal venous pressure (pvp), prealbumin (pa), and age, to predict postoperative at and provide a basis for adjustment of anesthetic doses during operation. methods: atotal of 71 patients with hepatic cirrhosis and hypersplenism at a...

The process of morning awakening is associated with a marked increase in cortisol secretion, the cortisol awakening response (CAR), as well as with a burst in cardiovascular (CV) activation. Whilst the CAR is largely driven by awakening-induced activation of hypothalamic-pituitary-adrenal axis, it is fine-tuned by direct sympathetic input to the adrenal gland. In parallel, awakening-induced act...
