Because high levels of cortisol are frequently observed in patients with septic shock, low levels of serum cortisol are considered indicative of relative adrenal insufficiency (RAI). This study was performed to investigate whether pretest clinical characteristics, including basal serum cortisol levels, are predictive of serum cortisol response to corticotropin and whether basal cortisol levels ...

BACKGROUND Female adolescent antisocial behavior is increasing, but little is known about the neuroendocrinologic aspects of this disorder. On the basis of reports of decreased cortisol levels in antisocial males, we investigated morning plasma cortisol levels in adolescent girls with conduct disorder (CD). METHODS Three plasma samples for cortisol levels were taken every 20 minutes between 8...

BACKGROUND There is some evidence that stress-induced cortisol increase leads to a decrease in pain, while lowering cortisol levels enhances pain sensitivity, but no study has yet investigated both pharmacological enhancement and reduction of cortisol levels in the same individuals. METHODS Firstly, we tested in 16 healthy individuals whether the treatment with hydrocortisone and dexamethason...

In a previous longitudinal study of basal cortisol levels and cognitive function in humans, we showed that elderly humans with 4- to 7-yr cumulative exposure to high levels of cortisol present memory impairments, compared with elderly humans with moderate cortisol levels over years. Here, we measured whether memory performance in two groups of elderly humans separated on the basis of their cort...

AIMS To follow the trend of leukocyte counts relative to the serum cortisol levels in hospitalized patients. METHODS We retrospectively reviewed the charts of 59 hospitalized patients who had sequential blood profiles during a 2-week period. RESULTS The study cohort was divided into two subgroups according to the categorical cortisol levels: those within the normal range (< 25 microg/dl; n ...

BACKGROUND Prior research has connected posttraumatic stress disorder (PTSD) to increased levels of catecholamines. However, studies of cortisol levels have produced mixed results. OBJECTIVE To examine urinary catecholamine and cortisol levels in individuals with PTSD in a community sample. DESIGN A representative cohort of young adult community residents, assessed periodically during a 10-...

RATIONALE Diagnosis of adrenal insufficiency in critically ill patients has relied on random or cosyntropin-stimulated cortisol levels, and has not been corroborated by a more accurate diagnostic standard. OBJECTIVE We used the overnight metyrapone stimulation test to investigate the diagnostic value of the standard cosyntropin stimulation test, and the prevalence of sepsis-associated adrenal...

Stress is inevitable in competitive sports. Table tennis in the world known as a fastest ball game that requires attention and control stress. The main purpose of this study was investigation of physiological stress responses in elite table tennis players during competition. 16 female table tennis players (age average of 18.7 &plusmn; 3.8, height average of 161.6 &plusmn; 3.4 cm and weight aver...

this study examined the effects of implanted cortisol (to imitate chronic stress) on the hematological responses and cortisol values of female great sturgeon, huso huso, after an endoscopic operation. at the beginning of experiment, all the fish were examined using an endoscope to evaluate gonad development. then, in order to mimic chronic stress following surgery, capsules of cocoa?? butter co...
