Objective: This study examined women's moods on work and off days

during different phases of the menstrual cycle. Method: Self-reports of the

moods angry, happy, sad, stressed, tired, and anxious were obtained on two work and two off days during the luteal and follicular phases of the menstrual cycle in 203 nurses. Individual differences in anger expression, anxiety, and hostility were assessed. Results: Ratings of anxious, stressed, and tired were higher and happy and sad were lower on the workday than the off day. Menstrual cycle phase was associated with mood differences depending on the day (work, off work) and individual differences in personality traits. Conclusions: The experience of moods in everyday life is affected by overall levels of stress and phase of the menstrual cycle. The findings suggest the need to refine sociopsychobiological and clinical models of mood regulation and of risk for disease. (C) 2004 Elsevier Inc. All rights reserved.

Impaired recovery and plasma concentration of intercellular adhesion molecule-1 (sICAM-1) were both highlighted as plausible and more established markers of cardiovascular disease, respectively. Hemodynamic patterns during recovery and their link with circulating levels of sICAM-1 were examined as predictors of 24-h blood pressure (ABP). Impedance cardiography measures and beat-to-beat BP were recorded in 45 healthy subjects during a 10-min baseline, four tasks, and four 10-min recovery periods. sICAM-1 levels at rest were determined by ELISA. ABP measures were obtained combining data from a work and an off day. Hierarchical regressions showed that patterns of compensatory changes in cardiac output and total peripheral resistance during recovery improved the prediction of ABP above and beyond resting and recovery BP, or reactivity hemodynamic patterns. Stress-induced recovery was essentially vascular in nature and a more vascular profile was associated with higher ABP and higher circulating levels of sICAM-1. The results suggest a link between recovery hemodynamics and cardiovascular risk.

BACKGROUND: Recent studies have shown that depressive disorder is associated with impaired baroreceptor or baroreflex sensitivity, which is proposed to be a predisposing factor for sudden death in patients with manifest cardiac disease. These studies have not evaluated the afferent and efferent components of the cardiac baroreflex loop or other baroreflex mechanisms that regulate target processes (cardiac metabolism and blood pressure variability) related to the impairment. The objective of this study was to gain more insight into autonomic functioning in depressive disorder to more fully examine the potential basis for increased cardiac mortality. METHODS: The subjects were 28 women and men with unipolar major depression who were taking antidepressant medications and who were in partial remission and free of cardiovascular or other serious disease, and 28 healthy control subjects matched for sex, age, and ethnicity. The two samples were compared for negative affective dispositions (anger expression, hostility, defensiveness, anxiety), spontaneous (closed-loop) baroreflex activity, heart rate, heart rate variability, systolic blood pressure, and heart rate-systolic blood pressure double product under resting conditions. RESULTS: Depressed patients showed a general disposition to anger suppression coupled with higher hostility and anxiety, and lower defensiveness. The patients showed higher general sympathetic activity (high levels of blood pressure, low-frequency heart rate variability) and lower parasympathetic-related activity (high heart rate and reduced high frequency heart rate variability) with affected cardiac metabolism estimated by the double product. Depressed patients had lower baroreflex sensitivity related to a higher gain of the afferent component of the baroreflex without respective gain adjustment of its efferent component (reflex gain 'de-afferentation'). It was coupled with a compensatory higher number of effective baroreflex reactions (reflex gating 're-afferentation'). Antidepressant agents and depressed mood had additional independent effects on baroreflex sensitivity through the efferent component of the cardiac baroreflex loop. CONCLUSIONS: The data indicate that different baroreflex components and mechanisms may be impaired in patients with depression and may contribute to their increased cardiac risk.

The objective of this study was to assess the relation between the intensity of single moods and of mood combinations on blood pressure (BP) and heart rate (HR). The subjects were 203 healthy registered nurses, all women, who were studied on two work and two off days. Ambulatory BP and HR were recorded every 20 minutes. On each occasion subjects rated their moods on a 5-point scale. Graded increases in BP and HR were shown with higher ratings of negative moods and decreases for a mood related to energy level. Little change was observed for a positive mood. These effects depended on concurrent changes in other moods. A positive mood countered the effects of a negative mood, whereas two negative moods resulted in unique patterns of BP and HR. The energy level mood moderated the cardiovascular effects of positive and negative moods. Ambulatory methods provide a way of probing into the nature and consequences of everyday emotional experiences.

OBJECTIVE: This study examined women's mood responsiveness associated with patterns of stress hormone levels in everyday situations. METHODS: Self-reports of negative, positive, and energy dimensions of mood were obtained from 203 nurses throughout the day on a workday and on an off-work day during the luteal and follicular phases of the menstrual cycle. Individual differences in daytime norepinephrine and cortisol were assessed. RESULTS: Patterns of norepinephrine and cortisol levels were associated with ratings of the following moods: tired, sad, and happy. Phase of the menstrual cycle and the day factor (workday, off-work day) modified the association of mood ratings and stress hormone patterns. CONCLUSION: The experience of negative mood is associated with both hypoarousal and hyperarousal conditions. A homeostatic arousal-related concept of mood regulation is discussed.

Objective: This study examined women’s mood responsiveness on work and off days during different phases of the menstrual cycle. Methods: Self reports of negative, positive, and energy dimensions of mood were obtained throughout the day on two work and two off days during the luteal and follicular phases of the menstrual cycle in 203 women nurses. Individual differences in daytime and nighttime epinephrine, norepinephrine, and cortisol were assessed. Results: High daytime norepinephrine, epinephrine, and cortisol levels were associated with higher ratings of stress and tired, and with lower ratings of happy. Phase of the menstrual cycle and the day factor (work day, off day) were also associated with mood differences, and the direction of the effects depended on hormone levels and hormone sampling period. Conclusion: The experience of moods is affected by arousal-related interaction of hormone levels with phase of the menstrual cycle and occupational stress.
