The enzyme 11-beta-hydroxysteroid dehydrogenase (11-beta-HSD) regulates glucocorticoid activity by converting cortisol into cortisone and vice versa. Frequent signs of major depression are elevated concentrations of circulating cortisol and ACTH. However, no information is available about the activity of 11-beta-HSD in this disorder. Therefore, we compared diurnal plasma concentrations of cortisol and cortisone and their ratios, reflecting 11-beta-HSD activity, in 25 severely depressed patients (Hamilton Depression Scale, 29 +/- 6; 14 men, 11 women, age 22-77 yr; mean, 47 +/- 16) and 30 control persons (20 men, 10 women age 23-85 yr; mean, 51 +/- 19). Cortisol and cortisone were measured at 0900 h, 1100 h, 1300 h, 2000 h, 2200 h, 0100 h, 0300 h, and 0700 h with specific RIAs after extraction. Both cortisol and cortisone concentrations were significantly increased in patients compared with controls (cortisol, 251.7 +/- 113.1 vs. 160 +/- 96.6 nmol/L; cortisone, 32.8 +/- 10.9 vs. 21.9 +/- 10.9 nmol/L). The calculated ratios of cortisol to cortisone were similar in controls and patients. Similar to cortisol, the circadian variation of cortisone was flattened in patients with the ratio of maximal cortisone to minimal cortisone being 1.9-fold higher in controls than in patients. There was no gender-specific difference in cortisone values neither in patients nor in controls. We conclude that in major depression increased cortisol is not due, at least partly, to an altered 11-beta-HSD activity or to a decrease in cortisone.

Changes in intraesophageal pH can influence myocardium perfusion via neural reflexes. The aim of this study was to estimate the relationships between intraesophageal pH and the course of electrocardiographic exercise test. 38 male patients with atypical chest pain in mean age 41.1 +/- 7.8 years were studied. In all among other 24-hours oesophageal pH monitoring and exercise test on running track with simultaneous oesophageal pH monitoring were made. Pathological acid reflux in 24-hours monitoring had 11 (29%) patients, exertional acid gastroesophageal reflux in 8 (21%) patients was found and significant ST interval depression in ecg in 11 (29%) patients was observed. The differences in patients quantity in respective subgroups were not significant. Patients with significant ST interval depression during exercise test, in comparison with patients without significant ecg changes, had lower HDL cholesterol level and higher values of daily and exertional gastroesophageal acid reflux parameters. Multiple-regression analysis showed that indicators of functional (pH-metry) and morphological (endoscopy and histology) oesophageal status were the independent factors determining variance of: exercise test duration, percentage of maximal heart rate during exercise test, double product value and maximal ST interval depression. In conclusion, changes in intraesophageal pH can influence exercise test course.

Moderate drinking of alcohol decreases the progress of atherosclerosis, cardiovascular morbidity and mortality rate and total mortality. The mechanisms of action have not been clarified yet, but changes of lipid metabolism, antioxidative effect and changes in hemostasis are accused to play the major role. Moderate drinking leads to the increase of HDL cholesterol and decrease of LDL cholesterol. Antioxidants are distributed throughout the skin of grapes and therefore are present in higher concentration in red wine. Alcohol decreases the fibrinogen level and increases tPA, inhibits platelet aggregation and reduces factor VIIc. It positively influences stress, fear, anxiety and depression. Optimal daily consumption should be 20 to 40 g in men and half of it in women. Everyday drinking is important. There is no big difference between drinking beer, wine or drinks. The most crucial is to keep the moderate level of consumption.

This study assessed psychosocial correlates of dyslipidemia, towards enabling improved tertiary prevention of macrovascular complications of diabetes mellitus (DM). We tested the hypothesis that psychosocial measures are related to high-density lipoprotein cholesterol (HDL-C) and triglyceride concentrations in a rural aboriginal population in British Columbia, Canada. Persons sampled were on-reserve registered Indians (n=198) with and at risk for Type 2 DM. Relationships between HDL-C and psychosocial variables were associated with glycemic status. For persons with diabetes and impaired glucose tolerance (n=44), quality of life and mastery were positively related (P<0.001), and depression inversely related (P<0.001), to HDL-C. An apparent lack of effect of behavior suggests the influence of emotional pathways involving autonomic-neuroendocrine axes. We recommend assessing mental health, and promoting mastery and diabetes quality of life through empowerment oriented diabetes management strategies, in negotiating culturally acceptable treatment of diabetic dyslipidemia for aboriginal people.

In males, aging, health and disease are processes that occur over physiologic time and involve a cascade of hormonal, biochemical and physiological changes that accompany the down-regulation of the hypothalamic-anterior pituitary-testicular axis. As aging progresses there are relative increases of body fat and decreases in muscle mass. The increased adipose tissue mass is associated with the production of a number of newly generated factors. These include aromatase, leptin, PAI-1, insulin resistance, and the dyslipidemias, all of which can lead to tissue damage. Fatty tissue becomes the focal point for study as it represents the intersection between energy storage and mobilization. The increase in adipose tissue is associated with an increase in the enzyme aromatase that converts testosterone to estradiol and leads to diminished testosterone levels that favor the preferential deposition of visceral fat. As the total body fat mass increases, hormone resistance develops for leptin and insulin. Increasing leptin fails to prevent weight gain and the hypogonadal-obesity cycle ensues causing further visceral obesity and insulin resistance. The progressive insulin resistance leads to a high triglyceride-low HDL pattern of dyslipidemia and increased cardiovascular risk. All of these factors eventually contribute to the CHAOS Complex: coronary disease, hypertension, adult-onset diabetes mellitus, obesity and/or stroke as permanent changes unfold. Other consequences of the chronic hypogonadal state include osteopenia, extreme fatigue, depression, insomnia, loss of aggressiveness and erectile dysfunction all of which develop over variable periods of time.

This study examines the correlations between serum lipid levels and psychological distress. There were 4444 consecutive attendees of general health clinics who participated in the study. Psychological symptoms were measured by the Taiwanese version of the Symptoms Check List 90, revised (T-SCL-90-R). Levels of fasting serum lipids, including total cholesterol, total triglycerides and high-density lipoprotein cholesterol (HDL-C), were determined. Multiple linear regression analyses, with adjustment for confounders, revealed that the concentration of HDL-C had significant inverse associations with scores of depression, somatization and phobic anxiety. Women with an HDL-C level lower than 35 mg/dl scored significantly higher on depression, interpersonal sensitivity, phobia, anxiety, somatization and aggressive hostility, while subjects with a total cholesterol concentration lower than 160 mg/dl scored significantly higher on anxiety, aggressive hostility, phobia, and psychoticism. This study provides, for the first time, comprehensive data derived from the Taiwanese population on the link between lipids and psychological symptoms, revealing a reverse correlation between depression and serum concentrations of HDL-C.

Theoretical and empirical studies suggest adverse effects of inbreeding on general vigour. The genetic architecture of physiological and biochemical cardiovascular risk factors is, furthermore, an unsolved issue. Our aim with this study is to investigate potential effects of inbreeding on stated risk factors in a relatively well demarcated Icelandic subpopulation. We used genealogical records to calculate coefficient of inbreeding and estimated the potential association of the coefficient with stated risk factors with known statistical methods. The results suggest absence of inbreeding depression with exception of HDL cholesterol.

In order to examine the relationship between depressive symptoms and the lipid metabolism in the elderly with hypertension, we recruited 311 outpatients aged 65 or older with hypertension and defined depression as patients with 6 or more symptoms on Geriatric Depression Scale short form. We further classified depressed patients into three groups: mild depressed with 6-7 symptoms, moderate depressed with 8-10 symptoms and severe depressed with 11 or more symptoms. Serum total cholesterol, serum HDL cholesterol and serum LDL cholesterol levels were significantly higher in female depressed patients than those in nondepressed patients (TC, 194.6 +/- 30.1 vs 208.0 +/- 32.8 p < 0.01; HDL, 67.3 +/- 19.3 vs 72.3 +/- 16.2 p < 0.01; LDL, 107.6 +/- 26.5 vs 116.0 +/- 29.1 p < 0.05). In male patients, serum lipids were not significantly associated with depressive symptoms but depressed patients were significantly older than nondepressed patients (75.3 +/- 6.2 vs 78.0 +/- 5.9 p < 0.05). Concerning the analysis of the severity of depression, serum total cholesterol and serum LDL cholesterol levels were significantly higher in mildly depressed patients than nondepressed patients in females and the same tendency was seen in male patients. No linear associations were shown between the severity of depression and serum lipids. We concluded that hyperlipidemia may be associated with depressive symptoms in elder patients with hypertension and that it might be related the severity of depression. We need to further investigate the relationship between depression and lipid metabolism in larger population samples.

During pregnancy, the total serum cholesterol concentration rises up to 43%, followed by a rapid fall after delivery. Mild depressive symptoms ('postpartum blues') are a common complication of the puerperium and affect 30-85% of women in the early postpartum period. Based on these observations, it has been suggested that the sudden fall in cholesterol levels after delivery could serve as a 'natural model' to test the suggested association between cholesterol and mood. The present study was designed to expand the database concerning the association between cholesterol levels and mood in the postpartum period and to address some methodological problems raised by previous studies. Forty-seven healthy primiparous women were interviewed with a structured clinical interview on two occasions: during late pregnancy (median: day -20 before the expected delivery) and during the early postpartum period (median: day 32 after delivery). On both occasions, serum concentrations of total and HDL cholesterol were measured and mood symptoms were assessed with the state form of Spielberger's State-Trait Anxiety Index (STAI), the state form of the State-Trait Anger Scale (STAS), and the Beck Depression Inventory (BDI). We found significant, albeit moderate, relationships between serum cholesterol levels and mood symptoms in the postpartum period that were not present during late pregnancy. Lower postpartum levels of total cholesterol were associated with symptoms of anxiety (r=-0.30, P=0.04), anger/hostility (r=-0.31, P=0.04), and depression (r=-0.35, P=0.02), and lower postpartum levels of HDL cholesterol were associated with symptoms of anxiety (r=-0.34, P=0.02). This study confirms that the physiological fall in blood lipids in the postpartum period can be a useful model to test the relationship between serum cholesterol levels and mood.

Athough education is considered an integral part of diabetes management, it remains low in the practical priorities of clinicians. We performed the first structured educational intervention in a diabetic outpatient department, where patients were controlled with no provider autonomy support available. We recruited 77 Type 1 (T1DM) and 154 Type 2 diabetic (T2DM) patients as well as 87 matched control subjects. Baseline evaluation included: medical interview; questionnaires concerning diabetes knowledge, diabetes quality of life, state-trait anxiety, depression and general perceived self-efficacy; biochemical examination (fasting blood glucose, HbA1c, lipids, uric acid, urinary glucose and albumin excretion). Of the 231 diabetic patients, 154 agreed to attend an educational course, yet only 101 patients (37 T1DM and 64 T2DM) completed it (intervention group) due to organisational barriers. Intervention and reference (non-participant patients) groups received identical medical care, except that the educational group met with the educator during five teaching sessions. Three to six months after the completion of the course, they underwent a final assessment. Prospective results were: 1) in T1DM, a reduction in HbA1c levels and an increase in plasma HDL cholesterol with no change in drug treatment (the reference group showed no change in HbA1c values despite an increased insulin dose), improved technical skill, knowledge, quality of life and self-efficacy; 2) in T2DM, a reduction in fasting plasma glucose and an improvement in knowledge and quality of life. Analysis of the cross-sectional data at baseline evidenced: 3) the same levels of anxiety, depression and general self-efficacy in diabetic patients compared with healthy control subjects; 4) lower diabetes-specific quality of life associated with established insulin treatment in T2DM; 5) significant gender differences among healthy as well as diabetic subjects in degree of psychological distress. Education by itself is more than simply offering information to people (even in a troubled context) and its infrequent incorporation in practice really contradicts resource efficiency.
