摘要:
ObjectiveEpidemiological data suggest that the presence of a depressed mood combined with cigarette smoking increases the risk of cancer at sites associated with smoking and at sites not associated with smoking. This study tested the hypothesis that major depression and smoking together contribute to a decline of natural killer cell (NK) activity, an immune parameter thought to be important in immune surveillance.MethodsA sample of 245 men were stratified into four groups: control subjects who were not smokers, control subjects who were smokers, subjects with major depression who were not smokers, and subjects with major depression who were smokers. Blood samples were obtained for measurement of total white blood cell (WBC) counts, differential cell counts, and assay of NK activity.ResultsMajor depression and cigarette smoking interact and were together associated with changes in WBC counts and NK activity. Depressed subjects who were smokers had higher WBC counts (p < .001) and lower NK activity (p < .01) than depressed nonsmoking subjects. However, WBC counts and NK activity were similar in control smokers and nonsmokers. Backward elimination regression analyses showed that the interaction of depression and smoking significantly (p < .001) predicted WBC counts and NK activity.ConclusionsThis study extends previous findings of immune alterations in patients with major depression. Major depression and smoking interact and together contribute to an elevation of total WBC count and a decline of NK activity.

摘要:
ObjectiveRecent evidence suggests that naturally occurring low cholesterol concentrations (<4.14 mmol/liter) are associated with depression as well as poor psychological health. For the most part, these associations have been observed in men. The current study assessed the relation of naturally occurring low lipid and lipoprotein concentrations to trait measures of depression and anxiety in 121 healthy young adult women.MethodsFasting lipid samples were collected at the same time as health history. Trait depression and anxiety were assessed using the Neuroticism, Extraversion, Openness-Personality Inventory (NEO-PI) depression subscale and Spielberger's Trait Personality Inventory (STPI) anxiety subscale. Analyses were conducted using both univariate and multivariate procedures.ResultsNEO depression was inversely associated with total cholesterol (p = .027), triglycerides (p = .012), and the ratio of total cholesterol to high-density lipoprotein cholesterol (p = .059). Similarly, STPI anxiety was inversely associated with total cholesterol (p = .002), low-density lipoprotein cholesterol (p = .016), triglycerides (p = .024), and ratio of total cholesterol to high-density lipoprotein cholesterol (p = .075). These associations were significant after adjustment for age, body mass index, physical activity, oral contraceptive use, and hostility. Neither depression nor anxiety was associated with high-density lipoprotein cholesterol. Univariate analyses indicated that women with low total cholesterol concentrations (<4.14 mmol/liter), relative to those with moderate to high cholesterol levels, were more likely to have higher scores on the NEO depression subscale (27 of 69 (39%) vs. 10 of 52 (19%)) and STPI anxiety subscale (24 of 69 (35%) vs. 11 of 52 (21%)).ConclusionsIn healthy young adult women, low lipid and lipoprotein concentrations are inversely associated with trait measures of depression and anxiety. These findings are independent of age, body mass index, physical activity, and other factors known to influence lipid concentrations.

摘要:
ObjectiveThe present study investigated the cardiovascular, genital, and endocrine changes in women after masturbation-induced orgasm because the neuroendocrine response to sexual arousal in humans is equivocal.MethodsHealthy women (N = 10) completed an experimental session, in which a documentary film was observed for 20 minutes, followed by a pornographic film for 20 minutes, and another documentary for an additional 20 minutes. Subjects also participated in a control session, in which participants watched a documentary film for 60 minutes. After subjects had watched the pornographic film for 10 minutes in the experimental session, they were asked to masturbate until orgasm. Cardiovascular (heart rate and blood pressure) and genital (vaginal pulse amplitude) parameters were monitored continuously throughout testing. Furthermore, blood was drawn continuously for analysis of plasma concentrations of adrenaline, noradrenaline, cortisol, prolactin, luteinizing hormone (LH), beta-endorphin, follicle-stimulating hormone (FSH), testosterone, progesterone, and estradiol.ResultsOrgasm induced elevations in cardiovascular parameters and levels of plasma adrenaline and noradrenaline. Plasma prolactin substantially increased after orgasm, remained elevated over the remainder of the session, and was still raised 60 minutes after sexual arousal. In addition, sexual arousal also produced small increases in plasma LH and testosterone concentrations. In contrast, plasma concentrations of cortisol, FSH, beta-endorphin, progesterone, and estradiol were unaffected by orgasm.ConclusionsSexual arousal and orgasm produce a distinct pattern of neuroendocrine alterations in women, primarily inducing a long-lasting elevation in plasma prolactin concentrations. These results concur with those observed in men, suggesting that prolactin is an endocrine marker of sexual arousal and orgasm.

摘要:
ObjectivePrevious studies of sex hormone concentrations in depression yielded inconsistent results. However, the activation of the hypothalamic-pituitary-adrenal system seen in depression may negatively affect gonadal function at every level of regulation. The objective of this study was to explore whether major depressive episodes are indeed associated with an alteration of gonadal function.MethodsTestosterone, pulsatile LH secretion, FSH, and cortisol were assessed using frequent sampling during a 24-hour period in 15 male inpatients with major depression of moderate to high severity and in 22 healthy comparison subjects (age range 22-85 years).ResultsAn analysis of covariance model showed that after adjustment for age only, daytime testosterone (p < .01), nighttime testosterone (p < .05), and 24-hour mean testosterone secretion (p < .01) were significantly lower in the depressed male inpatients. There was also a trend for a decreased LH pulse frequency in the depressed patients (p < .08).ConclusionsGonadal function may be disturbed in men with a depressive episode of moderate to high severity.

摘要:
ObjectiveThe aim of this study was to determine the gastric myoelectrical and emotional responses provoked by two psychophysiological stimuli known to cause in one case increased sympathetic nervous system activity and in the other increased parasympathetic nervous system activity.MethodsElectrogastrograms (EGGs) were recorded, and interbeat intervals (IBIs) were obtained from electrocardiographic recordings from 20 subjects during baseline and in response to a shock avoidance task (shock stimulus) and forehead cooling (dive stimulus). After each experimental period, subjects reported their emotional experience by rating descriptors ranging from serenity to excitement.ResultsDuring the shock stimulus, IBIs decreased significantly (p < .05), gastric tachyarrhythmias increased (p < .05), and emotional arousal increased, as indexed by reports of increased interest, excitement, and activation. In contrast, during the dive stimulus, IBIs increased (p < .05), but there were no associated changes in gastric myoelectrical activity or emotional arousal.ConclusionsAcute stress can evoke arousal and dysrhythmic gastric myoelectrical activity, and these acute changes, which occur in healthy individuals, may provide insight into functional gastrointestinal disorders.

摘要:
ObjectiveThe purpose of this study was to describe the sequence of psychosocial events and infections preceding the onset of chronic fatigue syndrome (CFS). This information was related to the temporal development of crucial symptoms in relation to the onset of, namely, fatigue, sadness, irritability, pain, and feeling of fever.MethodsA personal interview was conducted in 46 patients (mean age, 39.5 years; SD, 9 years) who fulfilled international CFS criteria. These patients were matched with regard to age and gender to 46 carefully matched control subjects. Twenty-three percent of the study subjects were men, and 77% were women. The patient at first identified the month that coincided with the onset of CFS. Similarly, each control subject was asked to identify a "very difficult period" within approximately the same period as the patient with whom the control subject was matched. A list of 14 different life events was perused. Participants were asked to identify for each month whether each of the listed events had occurred. Furthermore, they were asked to rate the importance of the events they had experienced. In addition, for each of the cardinal symptoms (fatigue, sadness, irritability, pain, and feeling of fever) and for each month, the subjects were asked to rate, on a visual analogue scale, the symptom intensity. Also, the number of infections was noted.ResultsA statistically significant group difference in fatigue intensity existed during the period 4 to 10 months before the onset of CFS. During the 3 months preceding the diagnosis for the CFS patients or the peak of the crisis for the control group, there was a dramatic rise in fatigue in both groups. The CFS group reached a much higher fatigue level, which leveled off somewhat during the first year of follow-up but still remained very high in comparison with the control group, which reached precrisis levels 4 months after the peak. Similar patterns were observed for fever and pain. With regard to sadness and irritability, no group difference was observed during the period preceding the crisis. In the patient group, the level stayed high throughout the whole first year of follow-up, whereas a slow return started in the control group; precrisis levels were reached after 1 year in this group. The prevalence ratio (CFS patients/control subjects) for negative events was around 1.0 for the periods 4 to 12 months preceding CFS but 1.9 during the quarter year preceding the onset. For infections, the prevalence ratio increased successively during the four quarters preceding CFS (from 1.4 to 2.3).ConclusionsAccording to the retrospective self-reports, there were differences between the groups in fatigue, pain, and feeling of fever during the months preceding the crisis. With regard to depressive and irritable feelings, no preillness differences were reported between the groups. There was a reported excess prevalence of both infections and negative life events during the quarter year preceding the onset of CFS or crisis. Potential sources of error are discussed. These findings must be replicated in longitudinal studies.

摘要:
ObjectiveNoncompliance with antihypertensive treatment is a significant health concern. Researchers have suggested that the absence of definable symptoms associated with elevated blood pressure (BP) attenuates patients' motivation to use medication. The current study evaluated the relation of psychological variables, including symptoms, perceptions of BP, and perceptions of medication efficacy, to physiological variables, including actual BP and the use of active antihypertensive medication vs. placebo.MethodsParticipants included 54 mildly hypertensive men who were participating in a placebo-controlled, double-blind study of the quality-of-life effects of antihypertensive therapies. Survey data and BP measurements were obtained during a series of clinic visits.ResultsMixed-model analysis of variance was used to evaluate both between- and within-person relations of psychological to physiological state. Results revealed significant within-person associations between predicted and actual BP. Negative mood was closely related to predicted, but not actual, BP. Participants were also relatively accurate in rating active medications as more effective than placebo. Between-persons analyses did not show relations of symptoms or moods to actual BP.ConclusionsThe significant within-person relations of estimated to actual BP suggest that some individuals may be able to estimate their own BP, although the accuracy of these estimates is limited. The findings may explain patients' belief that they can self-monitor BP. The results have implications for theories of the mental representation of illness and for efforts to improve compliance with antihypertensive therapy.
