RESUMO
Dental anxiety poses challenges for providing effective oral healthcare. While therapy dogs have shown promise in various medical and mental health contexts, their use for alleviating dental anxiety in adults remains underexplored. This study aimed to investigate the emotional and physiologic effects of therapy dogs on self-reported dental anxiety. Adults with dental anxiety were randomly assigned to an intervention group (DOG; n = 19) or a standard care group (SC; n = 14). Standard self-report measures were used to assess dental anxiety (Index of Dental Anxiety and Fear [IDAF-4C+]), depression (Patient Health Questionnaire 9), and generalized anxiety (Generalized Anxiety Disorder 7) prior to the intervention. Participants in the DOG group received a 10-minute therapy dog intervention before dental procedures in sessions 1 and 2, while participants in the SC group rested quietly for 10 minutes before their procedure. The SC participants received the 10-minute therapy dog intervention before dental procedures in the third and final session, while patients in the DOG group received no intervention prior to their third procedure. After the dental procedures, patients completed a questionnaire about their satisfaction with the dog therapy (Therapy Satisfaction Scale) and recorded their anxiety and comfort levels on visual analog scales. Continuous electrocardiographic recording measured heart rate variability during the intervention and dental procedure. Prior to the intervention, most participants (90.9%) met the IDAF-4C+ criteria for dental anxiety, with 7 (21.2%) meeting the criteria for dental phobia. The DOG group participants expressed high satisfaction with the therapy dog intervention. No significant differences in heart rate variability were observed between the groups during dental procedures. Therapy dogs can effectively manage dental anxiety in adults with mild to moderate dental anxiety, offering potential benefits for oral healthcare.

INTRODUCTION: In military training settings, stress can improve focus and motivation fostering effective learning. However, high perceived stress can be debilitating resulting in poor learning and clinical errors. Multiple studies have focused on medical residency stress; but there has been minimal focus on dental residents and even less on the impact of the unique stressors from the COVID-19 pandemic. The objectives of this study were to determine the impact of the COVID-19 pandemic on perceived stress of residents in a military dental residency training program and explore the association among perceived stress and anxiety, depression, sleep quality, and social support. MATERIALS AND METHODS: Dental residents (N = 20) at the Naval Postgraduate Dental School participated in this study. Residents were assessed via self-report measures quarterly from March 2020 through June 2021. The assessment included measures of anxiety (GAD-7), depression (PHQ-9), perceived stress (PSS), fatigue (FSI), and social support (DUKE-SSQ). RESULTS: Before the pandemic shutdown, 60% of participants reported high perceived stress. These residents reported an initial decrease in symptoms of anxiety, depression, and fatigue compared to residents reporting low pre-pandemic perceived stress but returned to baseline levels post-shutdown. Additionally, the high stress participants reported lower social support. CONCLUSIONS: Based on pre-pandemic perceived stress, participants responded differently to the impact of the pandemic shutdown. The low baseline stress participants may have a more robust sense of grit and resilience. These findings suggest that postgraduate dental training programs should integrate coping skills training opportunities, especially for residents reporting high perceived stress before residency.
RESUMO
BACKGROUND: Pain catastrophising is a maladaptive cognitive response characterised by an exaggerated negative interpretation of pain experiences. It has been associated with greater disability and poorer outcomes in chronic pain, to include several specific oro-facial pain conditions. The goal of this study was to examine pain catastrophising at a military oro-facial pain specialty clinic. METHODS: This retrospective chart review (RCR) examined information collected at initial examination from 699 new patients seen between September 2016 and August 2019 at the Orofacial Pain Center at the Naval Postgraduate Dental School (Bethesda, MD). Pain catastrophising, pain characteristics, psychosocial factors and sleep were assessed using standardised scales. Linear regression was used to evaluate associations of patient characteristics and pain intensity with pain catastrophising. Mediation analyses were done to characterise the extent to which the relationship between pain intensity and pain catastrophising may be explained by anxiety, depression and insomnia. RESULTS: Higher pain intensity, depression, anxiety, insomnia and younger age were each associated with higher pain catastrophising (all p < .05). A primary diagnosis of neuropathic pain was the strongest independent predictor of higher pain catastrophising. The relationship between pain intensity and pain catastrophising was partially mediated by anxiety, depression and insomnia. CONCLUSIONS: In this RCR of a population of oro-facial pain patients, those diagnosed with neuropathic pain were most likely to display high levels of pain catastrophising, a characteristic which is associated with poor long-term pain outcomes. This is the first study to show that, independent of other patient characteristics, those suffering from neuropathic pains displayed the highest levels of pain catastrophising. This highlights the importance of also addressing psychosocial factors in the treatment of neuropathic pain conditions, which are commonly treated using a predominantly biomedical approach. Additionally, anxiety, depression and insomnia each partially explains the relationship between pain intensity and pain catastrophising.

Paced breathing has shown efficacy in fibromyalgia (FM), but the mechanisms associated with symptom change are largely unknown. We investigated whether changes in respiratory rate (RR) alone resulted in autonomic changes during normal, paced, and mechanically assisted breathing in untrained FM patients and controls. Participants included 20 FM patients and 14 controls matched for age and body mass index. During a single visit, participants completed three 15-minute breathing sessions: 1) normal breathing, 2) slow-paced breathing, and 3) mechanically assisted breathing (continuous positive airway pressure) while supine. Continuous blood pressure and electrocardiogram were recorded, and measures of heart rate variability (HRV) and spontaneous baroreceptor sensitivity (sBRS) were calculated. During normal breathing, FM patients had higher heart rate (HR), but lower HRV and sBRS variables compared to controls with no difference in RR. Compared to the paced breathing condition, FM patients had significantly lower HR with higher HRV and sBRS variables during mechanically assisted breathing, despite no significant change in RR. Mechanically assisted breathing provided greater benefits in autonomic function than paced breathing in untrained FM patients. Future research will be needed to elucidate the central pathways involved in these autonomic changes and whether training in paced breathing can eventually replicate the results seen in mechanically assisted patients.
RESUMO
OBJECTIVES: This study compared persistent breast pain among women who received breast-conserving surgery for breast cancer and women without a history of breast cancer. METHODS: Breast cancer survivors (n=200) were recruited at their first postsurgical surveillance mammogram (6 to 15 mo postsurgery). Women without a breast cancer history (n=150) were recruited at the time of a routine screening mammogram. All women completed measures of breast pain, pain interference with daily activities and intimacy, worry about breast pain, anxiety symptoms, and depression symptoms. Demographic and medical information were also collected. RESULTS: Persistent breast pain (duration ≥6 mo) was reported by 46.5% of breast cancer survivors and 12.7% of women without a breast cancer history (P<0.05). Breast cancer survivors also had significantly higher rates of clinically significant persistent breast pain (pain intensity score ≥3/10), as well as higher average breast pain intensity and unpleasantness scores. Breast cancer survivors with persistent breast pain had significantly higher levels of depressive symptoms, as well as pain worry and interference, compared with survivors without persistent breast pain or women without a breast cancer history. Anxiety symptoms were significantly higher in breast cancer survivors with persistent breast pain compared with women without a breast cancer history. DISCUSSION: Results indicate that persistent breast pain negatively impacts women with a history of breast-conserving cancer surgery compared with women without that history. Strategies to ameliorate persistent breast pain and to improve adjustment among women with persistent breast pain should be explored for incorporation into standard care for breast cancer survivors.

OBJECTIVE: . Patients with complaints of orofacial pain (OFP) often have other body pain, yet many do not report these to their providers. Uncontrolled pain at any location may impact the successful management of an OFP complaint. The objective of this study was to determine the number of pain regions throughout the body, and the underreporting of pain, in patients who presented to a tertiary military OFP clinic. DESIGN: A retrospective chart review was conducted on 423 consecutive new patients. Patients were given three assessment opportunities to report their pain on a whole-body pain map: 1) prior to evaluation (Pt1), 2) following an explanatory statement by their provider on the relationship between pain and prognosis (Pt2), and 3) during directed pain inquiry of specific body regions (Pro). The pain map was divided into nine anatomical regions that were assessed for the presence of pain after Pt1, Pt2, and Pro. RESULTS: Initially, 60.5% of patients did not report all pain locations (Pt1). Following the explanatory statement (Pt2), 30.5% still did not report all pain. Following the completion of all assessment methods, the most commonly reported number of pain regions was five (17.0%), and 91.5% of patients reported multiple pain regions. CONCLUSIONS: Most patients had multiple pain complaints outside the chief complaint, yet the majority did not report these until multiple forms of assessment were utilized. These data encourage the use of a pain map, a verbal pain explanation, and directed pain questioning to more accurately capture pain location and facilitate multidisciplinary care.
RESUMO
We sought to examine the existential challenges that cancer survivors may experience as they strive to make meaning, regain their self-identity, cope with fear of recurrence, and experience feelings of grief and guilt. Lymphoma survivors (n = 429) completed the 2010 LIVE STRONG: survey and provided responses about meaning, cancer worry, security, identity, grief, guilt, and perceived functional impairment due to these concerns. Most survivors (73%-86%) endorsed existential concerns, with 30-39 percent reporting related perceived functional impairment. Concerns were associated with being female, younger, unmarried, and having undergone stem cell transplantation. Lymphoma survivors experience existential challenges that impact their life even years after diagnosis.

PURPOSE: With cancer survivors now numbering over 13 million in the United States, and expected to continue to increase, it is important to consider the needs of this growing population. In the literature, one of the most common complaints by cancer survivors is perceived cognitive dysfunction. Since the preponderance of the research has focused on breast cancer survivors, the purpose of the present study was to explore the prevalence and correlates of perceived cognitive dysfunction in a large sample of cancer survivors with representation across a wide range of different types of cancer. METHODS: A sample of 3108 post-treatment cancer survivors completed the 2010 LIVESTRONG survey as part of a larger study of cancer survivorship. Respondents completed standardized questions regarding current and past perceived cognitive dysfunction, as well as depressive symptoms, and demographic and medical variables. RESULTS: Current perceived cognitive dysfunction was reported by nearly half of respondents (45.7%), across a wide range of cancer types, with the highest prevalence among survivors of central nervous system cancers. Receiving chemotherapy and current report of depressive symptoms were both strongly associated with current perceived cognitive dysfunction. CONCLUSION: These findings contribute to a growing appreciation of the high prevalence of perceived cognitive dysfunction in survivors of a wide range of cancer types and the potential interactive effect of concurrent symptoms of depression. These findings highlight a need to develop more effective means of preventing or reducing cognitive dysfunction in cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Perceived cognitive dysfunction was reported in a wide range of cancer survivors. The potential interactive effect of symptoms of depression suggests the need to develop interventions targeting both cognitive dysfunction and depression to achieve improvements in cognitive functioning.

Positive health-promoting behaviors, including lifestyle factors (e.g., physical activity) and appropriate health service utilization (e.g., screening for secondary cancers), can minimize the health risks and challenges facing cancer survivors. The goal of this article is to examine factors associated with positive health behaviors in 2,615 posttreatment cancer survivors who completed the 2010 LIVESTRONG survey. Multivariate logistic regression was used to model odds of reporting each of six positive health behaviors "as a result of your experience with cancer": three "healthy lifestyle" behaviors and three "health care utilization" behaviors. In fully adjusted models, factors associated with greater likelihood of engaging in positive lifestyle behaviors (e.g., physical activity, changing diet) included sociodemographic factors, greater knowledge about how to reduce cancer risk; and reporting more psychological benefits due to cancer (ps <.01). Factors associated with greater likelihood of attending medical appointments and obtaining recommended cancer screenings included older age, better patient-provider communication, greater knowledge about how to reduce cancer risk, and more psychological benefits of cancer (ps <.01). Results suggest that knowledge about how to prevent cancer and benefit finding after cancer are related to positive health behaviors broadly, whereas better patient-provider communication is associated with positive cancer screening and health care utilization but not healthy lifestyle behaviors. Clinical interventions targeting these modifiable factors could maximize positive health behavior changes among cancer survivors, affecting risk for cancer recurrence as well as overall health and well-being.

Heart rate variability (HRV) is an objective and sensitive measure of integrated physiological functioning reflective of heart rhythm responsivity to internal and external demands. Reduced HRV is associated with vulnerability to stress and deterioration of medical and/or psychiatric conditions, while increased HRV is associated with a favorable treatment response and recovery from various medical and/or psychiatric conditions. Our previous review found that acute alcohol consumption caused decreased parasympathetic and increased sympathetic HRV effects in both nonalcoholic and chronic alcohol users. This review investigates the effects of chronic alcohol consumption on HRV in alcohol-dependent subjects and nondependent users. MEDLINE, Scopus, and PubMed were searched for human experimental and clinical trials that measured the effects of chronic alcohol use on HRV. Only publications that included a description of their study designs and clearly stated methodologies for data collections, and outcome measures were reviewed. We have reviewed a total of 24 articles. In nondependent users, low dose (approximating the recommended daily amount of 1 standard drink in women and 2 in men) use is associated with increased HRV parameters compared to those who drink less frequently or abstain altogether. A further increase in consumption is associated with decreased HRV compared to both abstainers and more moderate drinkers. HRV changes during withdrawal generally follow the same negative direction but are more complex and less understood. In dependent subjects, an improvement in HRV was seen following abstinence but remained reduced compared to nonalcoholic controls. This review demonstrates that HRV changes associated with chronic use follow a J-shaped curve. It supports recommendations that limit daily alcohol intake to no more than 2 drinks for men and 1 drink for women. Future studies should investigate HRV as a biomarker of alcoholism development and treatment response as well as the physiological basis for alcohol effects on HRV.

The goal of this study was to investigate psychophysiological characteristics in chronic pain patients during a pain stressor (cold pressor test) and after a brief diaphragmatic breathing intervention. Laboratory procedures were designed to quantify the effects of diaphragmatic breathing training at six breaths per minute on cardiac autonomic reactivity as indexed by root mean square of successive differences (RMSSD) and sequential baroreflex sensitivity (sBRS). Participants (n = 22) completed an initial laboratory assessment including the diaphragmatic breathing training session and were instructed to practice the technique for three ten-minute sessions daily. Self-monitoring of the use of the technique along with daily pain and fatigue scores was accomplished with hand-held computers. Participants returned to the lab for a second assessment after two-weeks. Participants demonstrating improved resting physiological status as indexed by change in RMSSD and sBRS after training (improvers) were compared to those not demonstrating any change in these variables (non-improvers). After two weeks of training, the improvers showed higher tolerance (p < .05) and lower blood pressure reactivity to the cold pressor test (p < .05) compared to the non-improvers. Time spent practicing the breathing technique was significantly different between the groups with the improvers maintaining daily practice close to the intervention recommendations. These results suggest the potential for significant improvements in autonomic functioning and inhibitory response to stress after a single intervention session and two weeks of practice.

Blood flow and vasodilatory responses are altered by age in a number of vascular beds, including the cerebral circulation. To test the role of prostaglandins as regulators of cerebral vascular function, we examined cerebral vasodilator responses to CO(2) (cerebrovascular reactivity) in young (26 ± 5 yr; 6 males/6 females) and older (65 ± 6 yr, 5 males/5 females) healthy humans before and after cyclooxygenase inhibition (using indomethacin). Middle cerebral artery velocity (MCAv) responses to stepped hypercapnia were measured before and 90 min after indomethacin. Changes in MCAv during the recovery from hypercapnia (vasoconstrictor responses) were also evaluated before and after indomethacin. Cerebrovascular reactivity was calculated using linear regression between MCAv and end-tidal CO(2). Young adults demonstrated greater MCAv (55 ± 6 vs. 39 ± 5 cm/s: P < 0.05) and MCAv reactivity (1.67 ± 0.20 vs. 1.09 ± 0.19 cm·s(-1)·mmHg(-1); P < 0.05) to hypercapnia compared with older adults (P < 0.05). In both groups MCAv and MCAv reactivity decreased between control and indomethacin. Furthermore, the age-related differences in these cerebrovascular variables were abolished by indomethacin. During the recovery from hypercapnia, there were no age-related differences in MCAv reactivity; however, indomethacin significantly reduced the MCAv reactivity in both groups. Taken together, these results suggest that cerebral blood flow velocity and cerebrovascular reactivity are attenuated in aging humans, and may be due to a loss of prostaglandin-mediated vasodilation.

OBJECTIVE: To assess whether a self-directed, computer-guided meditation training program is useful for stress reduction in hospital nurses. DESIGN: We prospectively evaluated participants before and after a month-long meditation program. The meditation program consisted of 15 computer sessions that used biofeedback to reinforce training. Participants were instructed to practice the intervention for 30 minutes per session, four times a week, for four weeks. Visual analogue scales were used to measure stress, anxiety, and quality of life (assessments were performed using Linear Analogue Self-Assessment [LASA], State Trait Anxiety Inventory [STAI], and Short-Form 36 [SF-36] questionnaires). Differences in scores from baseline to the study's end were compared using the paired t test. RESULTS: Eleven registered nurses not previously engaged in meditation were enrolled; eight completed the study. Intent-to-treat analysis showed significant improvement in stress management, as measured by SF-36 vitality subscale (P = .04), STAI (P = .03), LASA stress (P = .01), and LASA anxiety (P = .01). Nurses were highly satisfied with the meditation program, rating it 8.6 out of 10. CONCLUSIONS: The results of this pilot study suggest the feasibility and efficacy of a biofeedback-assisted, self-directed, meditation training program to help hospital nurses reduce their stress and anxiety. Optimal frequency of use of the program, as well as the duration of effects, should be addressed in future studies.

Alcohol consumption is associated with a broad array of physiologic and behavioral effects including changes in heart rate. However, the physiologic mechanisms of alcohol effects and the reasons for individual differences in the cardiac response remain unknown. Measuring changes in resting heart rate (measured as beats/min) has not been found to be as sensitive to alcohol's effects as changes in heart rate variability (HRV). HRV is defined as fluctuations in interbeat interval length which reflect the heart's response to extracardiac factors that affect heart rate. HRV allows simultaneous assessment of both sympathetic and parasympathetic activity and the interplay between them. Increased HRV has been associated with exercise and aerobic fitness, while decreased HRV has been associated with aging, chronic stress, and a wide variety of medical and psychiatric disorders. Decreased HRV has predictive value for mortality in general population samples and patients with myocardial infarction and used as an indicator of altered autonomic function. A significant inverse correlation was found between HRV and both the severity of depression and the duration of the depressive episode. HRV analysis provides insights into mechanisms of autonomic regulation and is extensively used to clarify relationships between depression and cardiovascular disease. This article will review the methodology of HRV measurements and contemporary knowledge about effects of acute alcohol consumption on HRV. Potential implications of this research include HRV response to alcohol that could serve as a marker for susceptibility to alcoholism. At present however there is almost no research data supporting this hypothesis.

PURPOSE: Primary palmar-plantar hyperhidrosis is the condition of excessive sweating of the hands and feet. For severe and medically refractory cases, endoscopic thoracic sympathotomy (ETS) is a bilateral ganglion-sparing disconnection between the stellate and T2 ganglion in an effort to minimize compensatory hyperhidrosis. The purpose of this study was to determine the effect of ETS on cardiac autonomic function. METHODS: Participants in this study were 22 otherwise healthy hyperhidrosis patients with 17 returning 1-12 months after surgery. Heart rate (HR) and blood pressure were collected at rest and during sequential nitroprusside/phenylephrine infusion (modified Oxford). To determine change in cardiac autonomic function, heart rate variability indices of RMSSD, LF and HF (log, nu) power were calculated. Sequential baroreflex sensitivity was also calculated. RESULTS: After surgery, resting HR on standardized ECG tended to be lower and reached significance during the modified Oxford baseline (p < 0.001). HRV changed significantly between assessments with an increase in HF (nu) and decrease in LF (nu) and LF (log) spectral ranges (p < 0.05), while the increase in RMSSD was marginally significant (p < 0.06). Compared with matched controls, HRV indices were significantly different before surgery, but similar after surgery. No change was detected in resting sequential baroreflex sensitivity, baroslope obtained by modified Oxford or QTc interval. CONCLUSIONS: We conclude that ETS changes cardiac autonomic modulation of HR to levels similar to controls. Despite the minimally destructive nature of ETS, effects on HRV are consistent with previously reported post-sympathectomy blunting of exaggerated sympathetic control associated with hyperhidrosis. No significant changes in the baroreflex indices suggest that ETS did not significantly affect blood pressure regulation.

PURPOSE: We studied patients with palmar hyperhidrosis before and after endoscopic thoracic sympathotomy (ETS) to determine the effect of chronic sympathetic denervation on (1) forearm blood flow (FBF) response to mental stress and (2) exercise tolerance. METHODS AND RESULTS: Twenty-two healthy patients were evaluated before ETS, and 17 returned after surgery (11 F; 19-32 years). We measured heart rate (HR; 12 lead), blood pressure, and FBF (plethysmography, ml dl(-1) min(-1)). Supine HR tended to decrease after ETS (69 ± 10 vs. 66 ± 6, p = 0.2). Mental stress FBF was recorded during baseline, 3-min Stroop color word test, and 2-min recovery. Mental stress responses were unaffected by ETS. However, during post-mental stress recovery period, ETS resulted in a significant elevation in FBF (2 ± 1 vs. 3 ± 1), FVC (3 ± 1 vs. 4 ± 2), and a decrease in FVR (52 ± 22 vs. 32 ± 16, p < 0.01 for all). ETS resulted in a reduction in pre-exercise seated baseline HR (94 ± 2.5 beats/min preoperatively vs. 84 ± 4.3 beats/min postoperatively, p < 0.05), maximal HR response to cycle exercise, and exercise systolic blood pressure (172 ± 5.2 mmHg pre-op vs. 158 ± 5.9 mmHg post-op, p < 0.05) but not mean or diastolic pressure. VO(2)max and exercise duration determined by cycle ergometry was unchanged. CONCLUSIONS: Functional evidence of upper limb denervation is observed during the FBF recovery period from mental stress and hemodynamic alterations associated with upright cycle exercise. However, the sustained exercise capacity suggests modest clinical consequences.

The purpose of this study was to examine the utility of using the NEO-FFI personality assessment as part of multi-dimensional psychological assessment in orofacial pain patients during the initial diagnostic visit. All patients completed an orofacial pain questionnaire and a battery of psychological questionnaires that cover a wide range of symptoms and behaviors important to developing a comprehensive treatment plan. For purposes of the present study, the NEO-FFI was included. Personality characteristics were within normal ranges compared to NEO-FFI norms. Regression analyses demonstrated higher self-reported pain severity was associated with lower openness. Higher psychological distress was associated with higher neuroticism, lower extraversion, and lower openness. In patients reporting a traumatic life experience, neuroticism and extraversion mediated the relationship between trauma-symptoms and psychological distress. The addition of a global personality measure in standard assessment batteries may help the clinician develop coping strategies and techniques based on individual characteristics of the pain patient. Greater understanding of the individual's personality characteristics will likely influence the nature of the pain management program and predict treatment outcomes.

OBJECTIVES: A primary goal of pain management for muscle-related pain is to reduce masticatory muscle activity. This study aimed to investigate masticatory muscle group activity and heart rate variability change when the tongue was placed on the palate or the floor of the mouth in a healthy pain-free sample. STUDY DESIGN: Participants were 23 females and 18 males with a mean age of 19.6 years (standard deviation = 1.5). Muscle activity was measured using surface electromyography and heart period were measured using electrocardiography. The experimental protocol consisted of 3 periods: baseline, tongue placement on the floor of mouth, and tongue placement on palate. RESULTS: Results indicated significantly more activity in the temporalis and suprahyoid muscle regions as well as a significant reduction in heart rate variability when the tongue was positioned on the palate compared with tongue position on the floor of the mouth. CONCLUSIONS: Instructions to place the tongue on the roof of the mouth are not instructions that will promote reduced physiological functioning (i.e., relaxation) but rather promote small, but potentially important increases in overall activity as indexed by muscle tone and cardiac function.

AIMS: To investigate (1) differences in heart rate variability (HRV) indices between masticatory muscle pain (MMP) patients and pain-free controls at rest, during a stressor condition, and during a post-stressor recovery period, and (2) factors including psychological distress, social environment, and family-of-origin characteristics in the MMP sample compared to a pain-free matched control sample. METHODS: Physiological activation and emotional reactivity were assessed in 22 MMP patients and 23 controls during baseline, stressor, and recovery periods. Physiological activity was assessed with frequency domain HRV indices. Emotional reactivity was assessed with the Emotional Assessment Scale. Analytic strategy began with overall 2 x 3 multivariate analyses of variance on physiological data followed by focused contrasts to test specific hypotheses regarding physiological and emotional status. Hypothesized differences between study groups on psychological and social-environmental variables were compared with univariate analyses of variance. RESULTS: The MMP patients showed physiological activation during the baseline period and significantly more physiological activation during the recovery period compared to the controls. This pattern was also present in emotional reactivity between the groups. The emotional and physiological differences between the groups across study periods were more pronounced in pain patients reporting a traumatic stressor. CONCLUSION: These results provide further evidence of physiological activation and emotional responding in MMP patients that differentiates them from matched pain-free controls. The use of HRV indices to measure physiological functioning quantifies the degree of sympathetic and parasympathetic activation. Study results suggest the use of these HRV indices may improve understanding of the role of excitatory and inhibitory mechanisms in patients with MMP conditions.

OBJECTIVE: The primary aim of this study was to determine the effects of smoking on treatment outcomes following multidisciplinary pain rehabilitation. A secondary aim was to assess the tobacco use characteristics of smokers with chronic pain. DESIGN: A prospective, nonrandomized, repeated measures design. SETTING: Multidisciplinary pain rehabilitation center at a tertiary referral medical center. PATIENTS: All patients (N = 193) consecutively admitted from August 2005 through February 2006. INTERVENTIONS: A 3-week outpatient multidisciplinary pain rehabilitation program. OUTCOME MEASURES: The Multidimensional Pain Inventory (MPI), Short Form-36 Health Status Questionnaire (SF-36), Center for Epidemiologic Studies-Depression scale (CES-D), Pain Anxiety Symptom Scale (PASS-20) and Pain Catastrophizing Scale (PCS) were administered at admission and dismissal. RESULTS: The study involved 49 (83% women) smokers and 144 (83% women) nonsmokers. The mean number of cigarettes smoked daily was 17.5 (SD 11.1) and the mean duration of smoking was 21.5 years (SD 12.1). After adjusting for demographic differences, repeated measures of analysis of covariance showed a main effect of smoking status for MPI affective distress (P = 0.008), CES-D (P = 0.001) and PCS (P = 0.011). An interaction of smoking status and time was found for the PASS-20 (P = 0.028), MPI affective distress (P = 0.033), MPI life control (P = 0.003) and SF-36 role-emotional (P = 0.004) subscale. While the majority of smokers were ready to consider smoking abstinence, 43% declined a brief smoking cessation intervention. CONCLUSIONS: In this series of patients undergoing multidisciplinary treatment for chronic pain, immediate treatment effects for a variety of outcome measures were similar or significantly better in smokers compared with nonsmokers.
