Choi SO, Choi JG, Yun JY. A Study of Brain Function Characteristics of Service Members at High Risk for Accidents in the Military. Brain Sci 2023; 13:1157. [PMID: 37626513 PMCID: PMC10452066 DOI: 10.3390/brainsci13081157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 07/23/2023] [Accepted: 07/29/2023] [Indexed: 08/27/2023] Open
Abstract
Military accidents are often associated with stress and depressive psychological conditions among soldiers, and they often fail to adapt to military life. Therefore, this study analyzes whether there are differences in EEG and pulse wave indices between general soldiers and three groups of soldiers who have not adapted to military life and are at risk of accidents. Data collection was carried out using a questionnaire and a device that can measure EEG and pulse waves, and data analysis was performed using SPSS. The results showed that the concentration level and brain activity indices were higher in the general soldiers and the soldiers in the first stage of accident risk. The body stress index was higher for each stage of accident risk, and the physical vitality index was higher for general soldiers. Therefore, it can be seen that soldiers who have not adapted to military life and are at risk of accidents have somewhat lower concentration and brain activity than general soldiers, and have symptoms of stress and lethargy. The results of this study will contribute to reducing human accidents through EEG and pulse wave measurements not only in the military but also in occupations with a high risk of accidents such as construction.

[PMID: 37028950 DOI: 10.1016/j.jvoice.2023.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 03/07/2023] [Accepted: 03/07/2023] [Indexed: 04/09/2023]
Abstract
OBJECTIVES Although there are many reports of voice improvement with intracordal trafermin (a basic fibroblast growth factor) injections under local anesthesia, few papers have documented the safety of trafermin. Therefore, we aimed to investigate whether trafermin is safer than control drugs (triamcinolone acetonide) early after intracordal injection under local anesthesia. METHODS We conducted a retrospective review from the medical records of patients who underwent intracordal injection with trafermin and triamcinolone acetonide under local anesthesia at our institution. Early postinjective complications were defined as changes in vital signs and chief complaints early after intracordal injection. RESULTS A total of 699 and 297 patients underwent intracordal injection under local anesthesia with trafermin and triamcinolone acetonide, respectively. Of these, 227 and 130 patients had early postinjective complications with trafermin and triamcinolone acetonide, retrospectively. The most common complications occurring with trafermin was increased blood pressure in 39 cases (5.58%): 17 cases (2.43%) of blood pressure increase of ≥20 mm Hg. Other complications included pharyngeal discomfort in 37 (5.29%), lightheadedness in 33 (4.72%), and phlegm discharge in 29 (4.15%). Triamcinolone acetonide caused pharyngeal discomfort in 28 patients (9.43%), phlegm discharge in 17 patients (5.72%), lightheadedness in 12 patients (4.04%), sore throat in 11 patients (3.70%), increased blood pressure in 10 patients (3.37%): 7 cases (2.36%) of blood pressure increase of ≥20 mm Hg, and dizziness in seven patients (2.36%). Statistical analysis of the complications between trafermin and triamcinolone acetonide showed no significant differences. CONCLUSIONS The proportion of early postinjective complications from intracordal injection of trafermin is no significant difference in that of triamcinolone acetonide. The results suggest that the early postinjective complications are not due to the drug action of trafermin, but rather to complications from the intracordal injection procedures. Intracordal trafermin injection may be safe in the short term.

Abstract
A “Workcation” (combining work and vacation) has become increasingly common. Traditionally, the workcation focus has been on productivity; however, data showing associations between workcations and improvements in employees’ health are lacking. Therefore, this study examines the effects of a workcation on blood pressure, arterial stiffness, heart rate, autonomic nervous system function, and physical activity. Twenty healthy employees participating in a five-day workcation project at a large private company agreed to participate in this study. Data on arterial stiffness, heart rate, autonomic nerve activity, and physical activity were collected before, during, and after the workcation. Arterial stiffness, blood pressure, and heart rate significantly decreased (p < 0.05); meanwhile, physical activity levels and parasympathetic function during sleep significantly increased during the workcation (p < 0.05). Thus, a workcation implies a new way of working that improves employees’ cardiovascular indices and parasympathetic function during sleep.

Abstract
Portable and wearable devices are becoming increasingly common in our daily lives. In this study, we examined the impact of anxiety-inducing videos on biosignals, particularly electrocardiogram (ECG) and respiration (RES) signals, that were collected using a portable device. Two psychological scales (Beck Anxiety Inventory and Hamilton Anxiety Rating Scale) were used to assess overall anxiety before induction. The data were collected at Simon Fraser University from participants aged 18–56, all of whom were healthy at the time. The ECG and RES signals were collected simultaneously while participants continuously watched video clips that stimulated anxiety-inducing (negative experience) and non-anxiety-inducing events (positive experience). The ECG and RES signals were recorded simultaneously at 500 Hz. The final dataset consisted of psychological scores and physiological signals from 19 participants (14 males and 5 females) who watched eight video clips. This dataset can be used to explore the instantaneous relationship between ECG and RES waveforms and anxiety-inducing video clips to uncover and evaluate the latent characteristic information contained in these biosignals.

One-day acceptance and commitment therapy (ACT) workshop improves anxiety but not vascular function or inflammation in adults with moderate to high anxiety levels in a randomized controlled trial. Gen Hosp Psychiatry 2021; 73:64-70. [PMID: 34619441 PMCID: PMC10044446 DOI: 10.1016/j.genhosppsych.2021.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 09/16/2021] [Accepted: 09/22/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE Acceptance and Commitment Therapy (ACT) is a behavioral intervention demonstrating sustained improvements in anxiety in individuals with chronic anxiety and psychological distress. Because anxiety disorders are associated with the development of cardiovascular disease (CVD), we hypothesized that a novel 1-day ACT workshop would both lower anxiety and improve vascular function in persons with moderate/high anxiety. METHODS In a randomized controlled study, 72 adults (age 33.9 ± 8.6 (SD) years) with baseline moderate/high anxiety completed a one-day ACT intervention (n = 44, age 33.9 ± 8.7 years) or control (n = 28, age 37.1 ± 10.1 years). Pre-specified secondary outcomes were measured over 12 weeks: aortic stiffness (carotid-femoral pulse wave velocity [cfPWV]), forearm vascular endothelial function (post-ischemic peak forearm blood flow [FBF] via plethysmography), and brachial artery flow-mediated dilation (FMD). Carotid artery stiffness (β-stiffness index), and inflammatory markers (C-reactive protein and tumor necrosis factor-alpha) were also explored. RESULTS Although the intervention had a significant and sustained effect on the primary outcome of anxiety as measured by the Beck Anxiety Inventory, the 1-day ACT workshop was not associated with improvement in vascular or inflammatory endpoints. The intervention was unexpectedly associated with increases in β-stiffness index that were also associated with changing trait anxiety. CONCLUSION Anxiety improvements did not translate into improvements in any of the vascular function outcomes. This may reflect a less-than-robust effect of the intervention on anxiety, failure in design to select those with vascular dysfunction, or not intervening on a relevant causal pathway.

Abstract
Cardiovascular complications have been demonstrated in patients with anorexia nervosa (AN) in both the state of starvation and during weight restoration, however, the underlying mechanisms remain unclear. The current study aimed to assess arterial stiffness via carotid-femoral pulse wave velocity (cfPWV) in the acute and weight-restored states of AN. The study also aimed to determine the association between psychological distress and cfPWV. The sample included 37 participants; 10 participants with AN, 17 who were weight-restored (AN-WR; minimum body mass index >18.5 for at least 12 months) and 10 healthy controls (HCs). cfPWV via applanation tonometry was conducted to assess arterial stiffness. Psychological distress was assessed using the depression anxiety stress scale (DASS-21) and the state-trait anxiety inventory (STAI). Between-group comparisons were performed to determine differences between groups, a two-stage hierarchical regression model was performed to determine the contribution of physiological and psychological variables on cfPWV and correlation analyses were also performed. Vascular stiffness was significantly increased in the AN and AN-WR groups, relative to HCs. The total DASS score was the only significant predictor of cfPWV across the sample. There were positive associations between cfPWV and depression, anxiety and stress, as assessed by the DASS. Furthermore, cfPWV was positively associated with STAI trait anxiety. Arterial stiffness was increased in individuals in the acute and weight-restored states of AN, demonstrating early signs of the development of arteriosclerotic cardiovascular disease. Increased arterial stiffness was associated with increased psychological distress, which may be a contributing mechanism to the increased cardiovascular risk in AN.

Abstract
BACKGROUND Patients with Crohn's disease have an increased aortic stiffness, a known cardiovascular risk factor. Anxiety, a key factor of the brain--gut axis in patients with Crohn's disease, is implicated in the pathogenesis and progression of the disease, and is linked with aortic stiffening in other clinical settings. OBJECTIVES Considering that depression is frequently linked to anxiety in Crohn's disease, we performed a mediation analysis to reveal the potential link between anxiety, depression and aortic stiffness in these patients. METHODS Multicentre observational cross-sectional study of 86 consecutive patients with Crohn's disease and 86 matched control individuals. The connections between anxiety, depression, disease duration, aortic pulse wave velocity (aPWV), brachial and central SBP were tested using partial least squares structural equations modelling. RESULTS In patients with Crohn's disease, anxiety (path coefficient: 0.220, P = 0.01) and disease duration (path coefficient: 0.270, P = 0.02) were associated with aPWV that in turn was associated with brachial SBP (path coefficient: 0.184, P = 0.03). These associations were even stronger in patients with active disease. The connection between anxiety and aPWV was in part mediated by central SBP (indirect effect: 0.090, P = 0.01; indirect-to-total effect ratio: 41%) as well as, in a pilot substudy, by sympathetic hyperactivity. Anxiety and depression were highly correlated in patients with Crohn's disease. Consequently, results were confirmed when anxiety was substituted by depression. CONCLUSION The connections of anxiety, depression and chronic inflammation with aPWV and SBP could suggest the first evidence of a brain--gut--vascular axis and new potential targets for therapy in patients with Crohn's disease.

Acute psychological stress, autonomic function, and arterial stiffness among women. Int J Psychophysiol 2020; 155:219-226.

Abstract
This study aimed to investigate the effect of acute psychological stress on autonomic function and arterial stiffness, and to test a mediating role of changes in autonomic function between acute stress and arterial stiffness. Eighty-five healthy female adults were randomized into either an experimental or control group. The Trier Social Stress Test (TSST) was used to induce acute psychological stress. Autonomic function (measured by pre-ejection period [PEP] from cardiac impedance and high frequency [HF] of heart rate variability [HRV]) and arterial stiffness (measured by carotid and femoral pulse wave velocity [cfPWV] and augmentation index [AIx]) were assessed before and after the TSST. The mean age of the participants was 28.78 (±9.84) years old. Experimental group participants had a significant increase in cfPWV (p = .025) and AIx (p = .017) following the stressor, compared with those in the control group, after controlling for age, body mass index, and systolic blood pressure. However, no significant group differences were observed in changes in PEP (p = .181) and HF (p = .058). Changes in PEP and HF were neither associated with changes in cfPWV (p = .975 and p = .654, respectively), nor in AIx (p = .376 and p = .323, respectively). The results suggest that even a brief period of mild to moderate stress, which does not cause sustainable changes in autonomic function, may still exert significant adverse effects on arterial stiffness. The changes in arterial stiffness were not related to changes in autonomic function. Future experimental studies with several measurement points are recommended to identify distinct effects of stress on autonomic function and arterial stiffness.

Abstract
BACKGROUND Myocardial infarction in the absence of obstructive coronary artery disease (MINOCA) accounts for approximately 5% - 6% of acute myocardial infarction (AMI) patients. Anxiety symptoms are common in patients with coronary artery disease (CAD), and are associated with a poor prognosis. However, the association between anxiety and MINOCA outcomes is less clear. HYPOTHESIS Anxiety will be associated with clinical outcomes in patients with MINOCA. METHODS AND RESULTS Between November 2014 and December 2016, 620 hospitalized patients with MINOCA were recruited from a single center. Within 7 days of coronary angiography, anxiety was assessed using the Zung Self-Rating Anxiety Scale. The primary endpoint was all-cause mortality; secondary endpoint was any major adverse cardiovascular event (MACE). After 3 years, 87 deaths and 151 MACE had occurred. Kaplan-Meier curves indicated the unadjusted rates of all-cause mortality (log-rank P = .045) and MACE (log-rank P = .023) were significantly higher in the anxiety group compared with the control group of patients without anxiety. Multivariate Cox regression analysis showed that clinically significant anxiety was an independent prognostic factor for all-cause mortality as well as MACE (hazard ratio [HR] = 1.547; 95% confidence interval [CI], 1.006-2.380; P = .047; HR = 1.460; 95% CI, 1.049-2.031; P = .025; respectively). CONCLUSIONS Anxiety is significantly and independently associated with an increased risk of all-cause mortality and MACE in patients with MINOCA.

Abstract
Anxiety symptoms co-occur with cardiovascular health problems, with increasing evidence suggesting the role of autonomic dysfunction. Yet, there is limited behavior genetic research on underlying mechanisms. In this twin study, we investigated the phenotypic, genetic and environmental associations between a latent anxiety factor and three cardiovascular autonomic function factors: interbeat interval (IBI, time between heart beats), heart rate variability (HRV, overall fluctuation of heart-beat intervals) and baroreflex sensitivity (BRS, efficiency in regulating blood pressure [BP]). Multivariate twin models were fit using data of female twins (N = 250) of the Twin Interdisciplinary Neuroticism Study (TWINS). A significant negative association was identified between latent anxiety and BRS factors (r = -.24, 95% CI [-.40, -.07]). Findings suggest that this relationship was mostly explained by correlated shared environmental influences, and there was no evidence for pleiotropic genetic or unique environmental effects. We also identified negative relationships between anxiety symptoms and HRV (r = -.17, 95% CI [-.34, .00]) and IBI factors (r = -.13, 95% CI [-.29, .04]), though these associations did not reach statistical significance. Findings implicate that higher anxiety scores are associated with decreased efficiency in short-term BP regulation, providing support for autonomic dysfunction with anxiety symptomatology. The baroreflex system may be a key mechanism underlying the anxiety-cardiovascular health relationship.

Abstract
BACKGROUND Radial pressure pulse wave (RPPW) examination has been a key diagnostic component of traditional Chinese medicine. The objective of this study was to investigate the changes in RPPW along with various hemodynamic variables after acupuncture stimulation and to examine the validity of pulse diagnosis as a modern diagnostic tool. METHODS We conducted acupuncture stimulation at both ST36 acupuncture points in 25 healthy volunteers. We simultaneously assessed the RPPW by pulse tonometry; heart rate variability (HRV) by electrocardiogram; photoplethysmogram (PPG) signals, respiration rate, peripheral blood flow velocity and arterial depth by ultrasonography; and cardiac output by impedance cardiography, before, during and after a session of acupuncture stimulation. RESULTS We observed consistent patterns of increased spectral energy at low frequency (<10 Hz) and pulse power using RPPW examination and in the amplitude and systolic area of the PPG signal during the entire acupuncture session. The low- and high-frequency domains of HRV increased and decreased, respectively, during the acupuncture session. The peripheral blood velocity rose shortly after needle insertion, reached a maximum in the middle of the session and decreased afterwards. The augmentation index (AIX) and pulse transit time (PTT) obtained from RPPW did not change significantly. CONCLUSION Acupuncture stimulation at ST36 in healthy subjects increased the peripheral pulse amplitudes (pressure pulse wave (PPW) and PPG), blood flow velocity (ultrasonography) and sympathetic nerve activity (HRV). The lack of changes in the AIX and PTT suggests that the increased pulse amplitudes and blood flow velocity may result from increased cardiac output.

Abstract
BACKGROUND Autonomic nervous system (ANS) dysfunction is a putative underlying mechanism for increased cardiovascular disease risk in individuals with psychiatric disorders. Previous studies suggest that this risk may be related to psychotropic medication use. In the present study we systematically reviewed and analyzed published studies of heart rate variability (HRV), measuring ANS output, to determine the effect of psychiatric illness and medication use. METHODS We searched for studies comparing HRV in physically healthy adults with a diagnosed psychiatric disorder to controls and comparing HRV pre- and post-treatment with a psychotropic medication. RESULTS In total, 140 case-control (mood, anxiety, psychosis, dependent disorders, k = 151) and 30 treatment (antidepressants, antipsychotics; k = 43) studies were included. We found that HRV was reduced in all patient groups compared to controls (Hedges g = -0.583) with a large effect for psychotic disorders (Hedges g = -0.948). Effect sizes remained highly significant for medication-free patients compared to controls across all disorders. Smaller and significant reductions in HRV were observed for specific antidepressants and antipsychotics. LIMITATIONS Study quality significantly moderated effect sizes in case-control analyses, underscoring the importance of assessing methodological quality when interpreting HRV findings. CONCLUSION Combined findings confirm substantial reductions in HRV across psychiatric disorders, and these effects remained significant even in medication-free individuals. Reductions in HRV may therefore represent a significant mechanism contributing to elevated cardiovascular risk in individuals with psychiatric disorders. The negative impact of specific medications on HRV suggest increased risk for cardiovascular disease in these groups, highlighting a need for treatment providers to consider modifiable cardiovascular risk factors to attenuate this risk.

Abstract
Endothelial dysfunction and autonomic nervous system dysfunction are both risk factors for atherosclerosis. There is evidence demonstrating that there is a close interrelationship between these two systems. In hypertension, endothelial dysfunction affects the pathologic process through autonomic nervous pathways, and the pathophysiological process of autonomic neuropathy in diabetes mellitus is closely related with vascular function. However, detailed mechanisms of this interrelationship have not been clearly explained. In this review, we summarize findings concerning the interrelationship between vascular function and the autonomic nervous system from both experimental and clinical studies. The clarification of this interrelationship may provide more comprehensive risk stratification and a new effective therapeutic strategy against atherosclerosis.

Abstract
AIM Increased angiogenic factors [vascular endothelial growth factor-A (VEGF-A) and angiopoietin-2 (Ang-2)] have been associated with vascular dysfunction and hypertension. Black Africans undergoing rapid urbanization present with elevated blood pressure (BP) and we aimed to determine whether angiogenic factors are elevated in urban versus rural Africans with normal and elevated BP. METHODS AND MATERIALS Africans (n = 272), matched for gender and age, were recruited from rural and urban communities in South Africa. Omron HEM-757 BP data were obtained and angiogenic markers in plasma and serum were determined. RESULTS Urban African men displayed a higher (43.90%) hypertension prevalence compared with their rural counterparts (18.52%) and disturbed angiongenic factors. Adjusted VEGF-A concentrations were higher in urban men and women compared with their rural counterparts. Similar VEGF-A levels were observed in rural and urban hypertensives. Logistic regression analysis demonstrated that VEGF-A and Ang-2 levels were associated with psychosocial stress but not with hypertensive status in Africans [odds ratios 1.01-1.09 (95% CI 1.01-1.15), p ≤ 0.05]. CONCLUSION Psychosocial stress per se was associated with disturbed VEGF-A and Ang-2. We suggest that hyperkinetic BP may act as compensatory mechanism when chronic psychosocial stress prevails, affecting vascular functioning and subsequent increased cardiovascular disease risk.

Abstract
OBJECTIVES To investigate the impact of anxiety on the prognosis of coronary artery disease (CAD) in patients of Chinese Han ethnicity and to explore the correlation between anxiety and the severity of coronary atherosclerosis. METHODS Between June 2007 and May 2009, 1007 hospitalized patients with CAD diagnosed by coronary angiography were recruited. The anxiety symptoms were investigated within 2 days after coronary angiography or percutaneous coronary intervention, using the Zung Self-Rating Anxiety Scale. The severity of coronary atherosclerosis was assessed using the modified Gensini score. One and a half years after discharge, the participants were evaluated at the outpatient clinic or by telephone. The primary outcome was the composite of all-cause death and nonfatal myocardial infarction (MI). RESULTS A total of 917 (91.1%) patients were evaluated during a mean follow-up period of 17 months. Thirty-five deaths (26 of cardiovascular and 9 of other causes) and 5 nonfatal MIs occurred. The Zung Self-Rating Anxiety Scale score assessed during hospitalization was significantly and independently associated with the Gensini score (β = 1.35, p < .001). Adjusted Cox proportional hazards models showed that anxiety symptoms predicted all-cause death and nonfatal MI (adjusted hazard ratio = 2.43, 95% confidence interval = 1.24-4.75, p = .009). CONCLUSIONS Anxiety was independently associated with the severity of coronary atherosclerosis and predicted worse outcome in patients with CAD of Chinese Han ethnicity.

Abstract
OBJECTIVE Cerebral autoregulation (CA) is the mechanism by which constant cerebral blood flow is maintained despite changes in cerebral perfusion pressure. CA can be evaluated by dynamic monitoring of cerebral blood flow velocity (CBFV) with transcranial Doppler sonography (TCD). The present study aimed to explore CA in chronic anxiety. METHODS Subjects with Hamilton anxiety scale scores ≥14 were enrolled and the dynamic changes of CBFV in response to an orthostatic challenge were investigated using TCD. RESULTS In both the anxious and the healthy subjects, the mean CBFV was significantly lower in the upright position than when supine. However, the CBFV changes from supine to upright differed between the anxious and the healthy groups. Anxious subjects showed more pronounced decreases in CBFV with abrupt standing. CONCLUSION Our results indicate that cerebrovascular modulation is compromised in chronic anxiety; anxious subjects have some insufficiency in maintaining cerebral perfusion after postural change. Given the fact that anxiety and impaired CA are associated with cardiovascular disease, early ascertainment of compromised cerebrovascular modulation using TCD might suggest interventional therapies in the anxious population, and improve the primary prevention of cardiovascular disease.

Abstract
We have developed a knowledge based approach for arterial stiffness estimation. The proposed new approach reliably estimates arterial stiffness based on the analysis of age and heart rate normalized reflected wave arrival time. The proposed new approach reduces cost, space, technical expertise, specialized equipment, complexity, and increases the usability compared to recently researched noninvasive arterial stiffness estimators. The proposed method consists of two main stages: pulse feature extraction and linear regression analysis. The new approach extracts the pulse features and establishes a linear prediction equation. On evaluating proposed methodology with pulse wave velocity (PWV) based arterial stiffness estimators, the proposed methodology offered the error rate of 8.36% for men and 9.52% for women, respectively. With such low error rates and increased benefits, the proposed approach could be usefully applied as low cost and effective solution for ubiquitous and home healthcare environments.

Abstract
OBJECTIVE Arterial stiffness is identified as a causative factor for hypertension. The purpose of this study was to explore the relationship between psychological stress and arterial stiffness in Korean Americans. METHODS A convenience sample of 102 Korean Americans (aged 21-60 years, 60% women) was recruited from North Carolina. Psychological stress was measured by the Perceived Stress Scale, the Social, Attitudinal, Familiar, and Environmental (SAFE) Acculturative Stress Scale, and the Spielberger's State-Trait Anxiety Inventory. Arterial stiffness was measured by carotid-femoral pulse wave velocity (cfPWV) using the SphygmoCor system (AtCor Medical, Australia). RESULTS This study shows that the emotional stress response, measured by anxiety, significantly predicted arterial stiffness (β=.25, p=.008), independently of such confounding factors as age, mean arterial pressure (MAP), gender, body mass index, smoking, education, and income. Anxiety was neither related to age (r=.12, p=.212) nor MAP (r=.14, p=.151). Additionally, this sample of Korean Americans had higher levels of psychological stress when compared to previous findings from studies of other racial/ethnic groups in the U.S. CONCLUSION Findings demonstrate that anxiety is a significant and independent determinant of arterial stiffness. Given that anxiety was not related to MAP, these findings suggest that arterial stiffness may be a pathway to explain the connection between anxiety and hypertension risk. Studies that scrutinize the relationship between anxiety and arterial stiffness are an important next step for future research. Further studies are also recommended to explore cultural factors and individual characteristics that may affect anxiety in Korean Americans.

Abstract
BACKGROUND Arterial stiffness gains attention as a potential mechanism underlying the frequently found association between depression or anxiety and cardiovascular disease. However, observations regarding stiffness and psychopathology were often based on small samples. The current study aimed to examine whether subjects with a diagnosis of depressive or anxiety disorder showed increased stiffness and to explore associations between various psychiatric characteristics and arterial stiffness. METHODS The sample included 449 cases with DSM-IV based lifetime diagnoses of depressive and/or anxiety disorder and 169 control subjects. Subjects were participating in the Netherlands Study of Depression and Anxiety and were aged 20 to 66 years. Characteristics included comorbidity, subtype of disorder, symptom severity and duration, age of onset, and use of antidepressant medication. Arterial stiffness was measured by calibrated radial tonometry (heart rate normalized central augmentation index [AIx75]; in percentage) and carotid M-mode ultrasound (distensibility coefficient). RESULTS After adjustment for covariates, AIx75 was increased in current (1-month) depression or anxiety (15.7% vs. 13.3% in control subjects, p = .01). Disorder characteristics associated with AIx75 were depression and anxiety comorbidity (15.3%, p = .02), higher depression severity (β = .10, p < .001) and anxiety severity (β = .10, p < .001), and longer symptom duration (β = .07, p = .01). No significant associations were found between distensibility coefficient and psychopathology. CONCLUSIONS Current depressive or anxiety disorders were associated with a higher central augmentation index, a manifestation of early wave reflection because of arterial stiffness. Exposure to depression and anxiety may therefore enhance the development and progression of atherosclerosis and other cardiovascular conditions.

Abstract
The recently reported cardiac autonomic dysregulation in patients with schizophrenia is characterized by a decreased vagal and an increased sympathetic modulation. This impairment possibly contributes to the increased cardiovascular mortality rate that is up to three times higher in these patients than in general population. The aim of this study was to characterize the autonomic regulation in schizophrenia and to evidence for a genetic influence. We investigated 36 patients with schizophrenia, 36 healthy first-degree relatives and 36 healthy controls. The autonomic regulation was classified applying linear and nonlinear methods of heart rate variability analysis. Healthy relatives were compared with healthy controls matched with respect to age and gender and with patients suffering from schizophrenia. Further on, schizophrenic patients were compared with healthy controls. The results show that the autonomic regulation in healthy relatives differs significantly from healthy controls (p〈0.01) and slightly from patients. However, the most significant differences could be found between patients and healthy controls (p〈0.0001). Relatives revealed decreased heart rate variability and demonstrated an altered autonomic modulation of heart rate and similar pattern of autonomic dysfunction as patients. This autonomic impairment found in relatives might indicate an underlying disease-inherent genetic vulnerability, especially since it is known that heart rate variability is partially under genetic control.

Abstract
Recent studies revealed cardiac autonomic dysfunction in patients with acute schizophrenia, which appears to be mainly related to reduced vagal and increased sympathetic modulation. To understand the significance of cardiac autonomic function in patients with schizophrenia, we extended these studies to relatives of patients. In this study, we assessed cardiac autonomic modulation in healthy first-degree relatives of patients with schizophrenia (n = 36) to investigate a putative genetic influence. Data were compared with control subjects matched for age, gender, and physical activity as well as to patients suffering from schizophrenia. First-degree relatives showed an attenuated, yet identical pattern in autonomic dysfunction as patients with decreased vagal modulation of heart rate, decreased baroreflex sensitivity, but no difference in blood pressure variability could be detected. The patients' relatives also showed a similar pattern in regards to QT variability. In addition, the subgroup comparison of offspring vs. siblings showed a significant difference in heart rate variability suggesting a higher degree of heritability in offspring. In conclusion, the pattern of autonomic dysfunction seen in patients and relatives might indicate underlying disease-inherent genetic vulnerability, especially because autonomic parameters are heritable. In addition, these findings may be of value to identify the high-risk group of patients' relatives in regards to serious cardiovascular events so that early preventive measures can be taken.

Abstract
OBJECTIVE Current evidence regarding the association between psychopathology and subclinical atherosclerosis show inconsistent results. The present study examined whether subclinical atherosclerosis was more prevalent in a large cohort of persons with depressive or anxiety disorders as compared to non-depressed and non-anxious controls. METHODS Baseline data from the Netherlands Study of Depression and Anxiety were used, including 2717 persons, free of clinical cardiovascular disease. Participants had a DSM-IV-based current or remitted depressive (major depressive disorder, dysthymia) or anxiety (social phobia, generalized anxiety disorder, panic disorder, agoraphobia) disorder (n=2115) or were healthy controls (n=602). Additional clinical characteristics (severity, duration, age of onset and medication) were assessed. Ankle-brachial index (ABI) was used as a measure of vascular risk and was categorized as low (<or=0.90) and mildly low ABI (0.90-1.11) indicating subclinical atherosclerosis, and high ABI (>1.40), which was previously designated as a cardiovascular risk factor, reflecting arterial stiffness and wall calcification. RESULTS As compared to normal controls, persons with current (i.e., past year) depressive, anxiety or comorbid depressive and anxiety disorders showed a two- to threefold increased odds of low ABI (OR=2.78, 95% CI=1.05-7.35; OR=3.14, 95% CI=1.25-7.85; OR=2.67, 95% CI=1.09-6.51, respectively). No associations were found with mildly low or high ABI. Also, we did not further find a differential role for symptoms severity, duration, age of onset, and use of psychotropic medication in the link between psychopathology and subclinical atherosclerosis. CONCLUSION Persons with current depressive or anxiety disorders were more likely to have subclinical atherosclerosis compared to healthy controls.

Abstract
OBJECTIVE The goal of this study is to assess the relationship between stress coping mechanisms and the risk of atherosclerosis in patients with Hwa-Byung. METHODS The Korean version of the Ways of Coping Checklist (WOCC) was administered to 50 patients with Hwa-Byung (49.1+/-10.1 years, 6 males). Brachial-ankle pulse wave velocity (baPWV) and serum cholesterol level were assessed in all participants. RESULTS After controlling for age, sex, diagnosis of hypertension, Body Mass Index (BMI), and serum cholesterol level, the score of seeking social support in coping strategies was negatively correlated with right and left baPWV (r=-0.356, p=0.016; r=-0.373, p=0.012, respectively). In addition, the score of active coping mechanism was negatively correlated with both sides of baPWV (r=-0.383, p=0.009; r=-0.389, p=0.008, respectively). CONCLUSION The seeking social support and active coping mechanism were inversely related to the severity of arterial stiffness in Hwa-Byung patients. Therefore, our result may suggest a possibility that coping strategies in Hwa-Byung patients are associated with the risk of atherosclerosis.

Abstract
OBJECTIVE We examined the role of social relationships and negative emotional traits in the development of central adiposity and arterial stiffness in healthy adolescents. DESIGN A prospective, longitudinal study examined 213 Black and White adolescents (50% Black, 51% female); 160 returned for a second assessment approximately 3 years later. MAIN OUTCOME MEASURES Psychosocial variables at both assessments were measured with the Measurement of Attachment Qualities (Carver, 1997), Social Relationships Index (study entry only; Uchino, Holt-Lunstad, Uno, & Flinders, 2001), Spielberger Trait Anger and Anxiety (Spielberger et al., 1979), and the Cook-Medley Hostility Scale (Cook & Medley, 1954). Central adiposity was assessed by waist-to-hip ratio (WHR) at both assessments and arterial stiffness by pulse wave velocity (PWV) at the second assessment only. RESULTS Linear regression models controlled for demographic variables and body mass index showed that adolescents with less Supportive Relationships (beta = -.121, p = .05) and higher Trait Anger (beta = .117, p = .05) had increased WHR over time, adjusted for initial WHR. Those with higher Attachment Anxiety (beta = .211, p = .01) and Total Hostility (beta = .234, p < .01) had greater PWV. Psychosocial associations for PWV were more apparent among Blacks. CONCLUSION Psychosocial variables may be important in the development of central adiposity and arterial stiffness in adolescence.

Abstract
BACKGROUND Atopic dermatitis has been shown to be associated with neurogenic and psychosocial factors. In related atopic diseases such as rhinitis or asthma, a shift in autonomic balance towards a parasympathetic modulation has been described. On the other hand, the psychiatric symptoms known for atopic dermatitis are often associated with decreased vagal modulation. Furthermore, an increased parasympathetic activity has been shown to exhibit anti-inflammatory effects, thus rather alleviating dermatitis symptoms. OBJECTIVE In order to address these intriguing discrepancies, we aimed to assess the autonomic state in patients suffering from atopic dermatitis. METHODS Heart rate variability assessment was performed in 30 patients and data were compared to those obtained from matched controls. Furthermore, questionnaires for disease activity and psychosocial stressors were employed. RESULTS Patients showed higher values for parasympathetic modulation than controls. This was mainly reflected by an increase in the root mean square of successive differences (RMSSD). This parameter further correlated with dermatological symptoms and the time since the last severe exacerbation of the disease. In addition, subgroups of patients with dyshidrosis or photophobia showed significant differences in autonomic modulation under deep respiration. Moreover, cardiac autonomic modulation was hardly altered upon postural change, indicating that autonomic reactivity is only mildly influenced in these patients. CONCLUSION Patients with atopic dermatitis showed an autonomic dysbalance which is comparable to other diseases related to atopy or allergy. Our findings point to the question whether these alterations are disease-inherent or counter-regulatory, which should be addressed in future studies.

Pulses from the right and left sides of normal subjects are highly correlated at each segmental level. However, some evidence suggests that the right hemisphere has a greater effect on parasympathetic activity, as there may be a right hemisphere disadvantage in patients with low cardiac vagal function. Decreased vagal function is associated with vascular dysfunction and hypertension. METHODS We compared normal controls (n = 22), patients with anxiety (n = 26), and patients with cardiovascular disease (n = 72) using the Vascular Profiler (VP-1000), which enables the measurement of ankle and brachial blood pressure (BP) in both arms (brachial), both legs (ankle) and carotid artery, and lead I electrocardiogram and phonocardiogram. Using these signals, PWV, and arterial stiffness index % were calculated for the comparison of these measures on the right and left sides of the body. RESULTS Patients with anxiety and cardiovascular disease had significantly higher left-right differences in heart-ankle pulse wave velocity, brachial-ankle pulse wave velocity, and arterial stiffness index percentage compared with that of normal controls. Our data also showed significant differences between left-right vascular indices in patients with anxiety and cardiovascular disease (p < .00001); there was no such significant difference in normal controls. CONCLUSIONS These results may implicate an exaggerated vagal withdrawal in the left extremities resulting in higher PWV in patients with anxiety and cardiovascular illness.

Abstract
BACKGROUND Some studies suggest that it is important to take the end of "T" wave to quantify QT-interval variability, which signifies cardiac repolarization lability, as there is substantial and important information beyond the peak of the T wave on the surface electrocardiogram. METHODS In this study, we examined the relationship between the variability of beat-to-beat RTe (beginning of R-peak to T-end) and the variability of RTp (R-peak to T-peak) in the following groups: normal controls (n = 26), patients with anxiety (n = 26), and patients with cardiovascular disease with or without diabetes (n = 63). We obtained ECG sampled at 1024 Hz in lead II configuration in supine posture to obtain beat-to-beat interbeat interval (R-R) and RT-interval variability for 256 seconds. RESULTS We found significant positive correlations (r = 0.8; P < 0.00001) in normal controls and patients with anxiety between the variability of RTeVI and RTpVI (RTe and RTp variability indices, respectively, corrected for the mean of RTe and RTp and the mean and the variance of R-R). These correlations were also statistically significant in the medically ill group but the r values were much smaller (r = 0.45 in various groups). The slopes were also significantly different between the two groups (P < 0.001). Bland-Altman plots also showed better agreement between the two measures in the controls and patients with anxiety compared to the group with cardiovascular disease. CONCLUSIONS These findings have methodological implications for studies comparing people with and without overt cardiovascular illness. While RTe or RTp variability index may be used interchangeably in normal controls and some patients with no overt cardiovascular problems, it may be more prudent to use both RTe and RTp variability indices in patients with cardiovascular illness. These indices, especially RTeVI, may provide different information about cardiac repolarization lability. Future studies should address the importance of the relative usefulness of these two measures especially in cardiac patients before and after successful treatment.
