Blood Pressure Increases During A Simulated Night Shift In Persons At Risk For Hypertension, James A. Mccubbin, June J. Pilcher, D Dewayne Moore
Blood Pressure Increases During A Simulated Night Shift In Persons At Risk For Hypertension, James A. Mccubbin, June J. Pilcher, D Dewayne Moore

Background: Shift work with sleep disruption is a systemic stressor that may possibly be associated with blood pressure dsyregulation and hypertension. Purpose: We hypothesize that rotation to a simulated night shift with sleep deprivation will produce blood pressure elevations in persons at risk for development of hypertension. Method: We examined the effects of a simulated night shift on resting blood pressure in 51 diurnal young adults without current hypertension. Resting blood pressure was monitored throughout a 24 hour period of total sleep deprivation with sustained cognitive work. Twelve participants (23.5%) reported one or more parents with a diagnosis of hypertension. …
Coping Styles, Opioid Blockade, And Cardiovascular Response To Stress, Stephen Bruehl, James Mccubbin, John Wilson, Thomas Montgomery, Paloma Ibarra, Charles Carlson
Coping Styles, Opioid Blockade, And Cardiovascular Response To Stress, Stephen Bruehl, James Mccubbin, John Wilson, Thomas Montgomery, Paloma Ibarra, Charles Carlson

We investigated the hypothesis that the effects of Monitoring and Blunting coping styles are mediated in part by endogenous opioids. Mean arterial pressure (MAP) and heart rate (HR) were measured in 39 males before, during, and after a mental arithmetic stressor. Each subject experienced the protocol once under opioid blockade (naltrexone) and once in a placebo condition, in counterbalanced order. Monitoring and Blunting were assessed using the Miller Behavioral Style Scale. High Blunting and high Monitoring were both associated with poorer MAP recovery under opioid blockade than in the placebo condition. Similar effects were noted for Blunting on the measure …

The present study was designed to determine the role of endogenous opioid mechanisms in the circulatory effects of relaxation training. Opioid mechanisms were assessed by examination of the effects of opioid receptor blockade with naltrexone on acute cardiovascular reactivity to laboratory stress before and after relaxation training. 32 young men with mildly elevated casual arterial pressure were recruited for placebo-controlled naltrexone stress tests and relaxation training. The results indicated that relaxation training significantly reduced the diastolic pressure response to mental arithmetic stress. Opioid receptor blockade with naltrexone antagonized the effects of relaxation training. These findings suggest that some of the …
Psychological Coping With Acute Pain: An Examination Of The Role Of Endogenous Opioid Mechanisms, Stephen Bruehl, Charles Carlson, John Wilson, Jane Norton, George Colclough, Marianne Brady, Jeffrey Sherman, James Mccubbin

This study examined the relationship among endogenous opioids, Monitoring and Blunting coping styles, and acute pain responses. Fifty-eight male subjects underwent a 1-min pressure pain stimulus during two laboratory sessions. Subjects experienced this pain stimulus once under endogenous opioid blockade with naltrexone and once in a placebo condition. Blunting was found to be negatively correlated with pain ratings, but this relationship was significantly more prominent under opioid blockade. Results for coping behaviors subjects used to manage the experimental pain were generally consistent with the Blunting results, indicating that cognitive coping was related more strongly to decreased pain ratings and cardiovascular …

This study examined the role of endogenous opioids in the relation between hostility and cardiovascular stress responsiveness. Forty-six mencompleted the Cook-Medley Hostility Scale, and experienced a laboratory pain stressor once under opioid blockade and once under placebo. Hostility scores were significantly related to the magnitude of change in cardiovascular reactivity/recovery resulting from opioid blockade. Low scorers on the Cynicism subscalc displayed increases in heart rate (HR) reactivity under blockade relative to placebo, with reactivity decreases noted in high scorers. Low Hostile Affect scores were similarly associated with impaired diastolic blood pressure recovery under opioid blockade. HR recovery results were somewhat …
The Relationship Between Pain Sensitivity And Blood Pressure In Normotensives, Stephen Bruehl, Charles Carlson, James Mccubbin
The Relationship Between Pain Sensitivity And Blood Pressure In Normotensives, Stephen Bruehl, Charles Carlson, James Mccubbin
James A. McCubbin
Hypertension has been found to be related to decreased sensitivity to painful stimuli. The current study explored whether this relationship extends into the normotensive range of blood pressures. Resting blood pressures were assessed in 60 male normotensives. Subjects then underwent a l min finger pressure pain stimulation trial. Pain ratings were inversely related to resting systolic blood pressure. This relationship was unrelated to emotional state or coping styles. Multiple regression analyses indicated that over one-third of the variance in pain ratings can be accounted for by resting blood pressure, coping style, and emotional state.
An Unusual Reaction To Opioid Blockade With Naltrexone In A Case Of Posttraumatic Stress Disorder, Paloma Ibarra, Stephen P. Bruehl, James A. Mccubbin, Charles R. Carlson, John F. Wilson, Jane A. Norton, Thomas B. Montgomery

An unusual behavioral and cardiovascular reaction was observed during opioid blockade with naltrexone in a 32-year-old male who met DSM III-R criteria for post-traumatic stress disorder (PTSD). As part of an ongoing placebo-controlled investigation of the effects of naltrexone on laboratory and ambulatory blood pressure reactivity, this participant reported experiencing feelings of rage, explosive behavior, and other unpleasant symptoms. When compared to all other subjects (N=24), this individual showed significantly greater effects of naltrexone on blood pressure reactivity during the laboratory stressor. His ambulatory blood pressures, when compared to placebo, were significantly increased during the 24-hr period following naltrexone. The …
