Heartache and heartbreak--the link between depression and cardiovascular disease. Nat Rev Cardiol. 2012;9:526-539. [PMID: 22733213 DOI: 10.1038/nrcardio.2012.91]

Steroid hormone secretion after stimulation of mineralocorticoid and NMDA receptors and cardiovascular risk in patients with depression

Major depressive disorder (MDD) is associated with altered mineralocorticoid receptor (MR) and glucocorticoid receptor function, and disturbed glutamatergic signaling. Both systems are closely intertwined and likely contribute not only to the pathophysiology of MDD, but also to the increased cardiovascular risk in MDD patients. Less is known about other steroid hormones, such as aldosterone and DHEA-S, and how they affect the glutamatergic system and cardiovascular disease risk in MDD. We examined salivary cortisol, aldosterone, and DHEA-S secretion after stimulation of MR and glutamatergic NMDA receptors in 116 unmedicated depressed patients, and 116 age- and sex-matched healthy controls. Patients (mean age = 34.7 years, SD = ±13.3; 78% women) and controls were randomized to four conditions: (a) control condition (placebo), (b) MR stimulation (0.4 mg fludrocortisone), (c) NMDA stimulation (250 mg D-cycloserine (DCS)), and (d) combined MR/NMDA stimulation (fludrocortisone + DCS). We additionally determined the cardiovascular risk profile in both groups. DCS had no effect on steroid hormone secretion, while cortisol secretion decreased in both fludrocortisone conditions across groups. Independent of condition, MDD patients showed (1) increased cortisol, increased aldosterone, and decreased DHEA-S concentrations, and (2) increased glucose levels and decreased high-density lipoprotein cholesterol levels compared with controls. Depressed patients show profound alterations in several steroid hormone systems that are associated both with MDD pathophysiology and increased cardiovascular risk. Prospective studies should examine whether modulating steroid hormone levels might reduce psychopathology and cardiovascular risk in depressed patients.

Retinal correlates of psychiatric disorders

Diagnosis and monitoring of psychiatric disorders rely heavily on subjective self-reports of clinical symptoms, which are complicated by the varying consistency of accounts reported by patients with an impaired mental state. Hence, more objective and quantifiable measures have been sought to provide clinicians with more robust methods to evaluate symptomology and track progression of disease in response to treatments. Owing to the shared origins of the retina and the brain, it has been suggested that changes in the retina may correlate with structural and functional changes in the brain. Vast improvements in retinal imaging, namely optical coherence tomography (OCT) and electrodiagnostic technology, have made it possible to investigate the eye at a microscopic level, allowing for the investigation of potential biomarkers in vivo. This review provides a summary of retinal biomarkers associated with schizophrenia, bipolar disorder and major depression, demonstrating how retinal biomarkers may be used to complement existing methods and provide structural markers of pathophysiological mechanisms that underpin brain dysfunction in psychiatric disorders.

Inflammation, insulin resistance and neuroprogression in depression

Chronic low-grade inflammation has been observed in major depression and other major psychiatric disorders and has been implicated in metabolic changes that are commonly associated with these disorders. This raises the possibility that the effects of dysfunctional metabolism may facilitate changes in neuronal structure and function which contribute to neuroprogression. Such changes may have implications for the progress from major depression to dementia in the elderly patient. The purpose of this review is to examine the contribution of inflammation and hypercortisolaemia, which are frequently associated with major depression, to neurodegeneration and how they detrimentally impact on brain energy metabolism. A key factor in these adverse events is insulin insensitivity caused by pro-inflammatory cytokines in association with desensitised glucocorticoid receptors. Identifying the possible metabolic changes initiated by inflammation opens new targets to ameliorate the adverse metabolic changes. This has resulted in the identification of dietary and drug targets which are of interest in the development of a new generation of psychotropic drugs.

The pursuit of euthymia

Psychiatrists often consider the positive characteristics displayed by a patient in their clinical judgment, yet current assessment and treatment strategies are shifted on the side of psychological dysfunction. Euthymia is a transdiagnostic construct referring to the presence of positive affects and psychological well-being, i.e., balance and integration of psychic forces (flexibility), a unifying outlook on life which guides actions and feelings for shaping future accordingly (consistency), and resistance to stress (resilience and tolerance to anxiety or frustration). There is increasing evidence that the evaluation of euthymia and its components has major clinical implications. Specific instruments (clinical interviews and questionnaires) may be included in a clinimetric assessment strategy encompassing macro-analysis and staging. The pursuit of euthymia cannot be conceived as a therapeutic intervention for specific mental disorders, but as a transdiagnostic strategy to be incorporated in an individualized therapeutic plan. A number of psychotherapeutic techniques aiming to enhance positive affects and psychological well-being (such as well-being therapy, mindfulness-based cognitive therapy, and acceptance and commitment therapy) have been developed and validated in randomized controlled clinical trials. The findings indicate that flourishing and resilience can be promoted by specific interventions leading to a positive evaluation of one's self, a sense of continuing growth and development, the belief that life is purposeful and meaningful, satisfaction with one's relations with others, the capacity to manage effectively one's life, and a sense of self-determination.

Increased expression of plasminogen activator inhibitor-1 (PAI-1) is associated with depression and depressive phenotype in C57Bl/6J mice

Plasminogen activator inhibitor 1 (PAI-1), which is elevated in numerous disease states, has been implicated as a stress-related protein involved in the pathogenesis of depression. We measured PAI-1 in the plasma of healthy and depressed individuals and assessed plasminogen activator (PA) expression and regulation by PAI-1 in cultured normal human astrocytes (NHA). Elevated plasma PAI-1 levels were found in depressed patients. Brain tissues from depressed individuals also showed stronger expression of hippocampal PAI-1 by confocal imaging in comparison to healthy individuals. Using a lipopolysaccharide-induced inflammatory model of depression in mice, we measured PAI-1 in murine plasma and brain, by ELISA and immunohistochemistry, respectively. Similar elevations were seen in plasma but not in brain homogenates of mice exposed to LPS. We further correlated the findings with depressive behavior. Ex vivo experiments with NHA treated with proinflammatory cytokines implicated in the pathogenesis of depression showed increased PAI-1 expression. Furthermore, these studies suggest that urokinase-type plasminogen activator may serve as an astrocyte PA reservoir, able to promote cleavage of brain-derived neurotrophic factor (BDNF) during stress or inflammation. In summary, our findings confirm that derangements of PAI-1 variably occur in the brain in association with the depressive phenotype. These derangements may impede the availability of active, mature (m)BDNF and thereby promote a depressive phenotype.

Buddhist meditation for vascular function: A narrative review

Background

High blood pressure represents an important risk factor for diseases related to cardiovascular system and is directly associated with high oxidative stress, inflammation and vascular endothelial dysfunction. Recently, there is promising data available to suggest that meditation-based low-cost and low-risk lifestyle modification strategies may provide beneficial effects on chronic inflammation, oxidative stress and maintenance of blood pressure, both in young and older adults. This review aims to summarize the evidence regarding the effectiveness of Buddhist meditation for vascular endothelial function and blood pressure.

Method

A search was conducted using Ovid MEDLINE, Scopus, CINAHL and PsycINFO for articles published from 1990 to 2018.

Results

Relevant articles (n = 407) were reviewed and 5 met selection criteria. Several lines of studies have provided compelling data showing that Buddhist meditation approach was effective in improving inflammation and vascular function (endothelial vasodilation and arterial stiffness) in both young and elderly cohorts. Particularly, Buddhist meditation approach has shown to be effective in reducing plasma inflammatory markers, increasing nitric oxide concentration and improving vascular endothelial function and glycemic control, which in turn can be favorable factors for demonstrated positive effects of Buddhist meditation on blood pressure and vascular function.

Conclusion

This paper presents brief overview of clinical outcomes of complementary therapeutic approach of Buddhist meditation in vascular function. In future, well-structured systematic reviews are essential to report specificity of Buddhist mindfulness-based approach on vascular function, blood pressure and other cardiovascular risk factors.

A meta-analysis of heart rate variability in major depression

BACKGROUND

Major depression (MD) is a risk factor for cardiovascular disease. Reduced heart rate variability (HRV) has been observed in MD. Given the predictive value of HRV for cardiovascular health, reduced HRV might be one physiological factor that mediates this association.

METHODS

The purpose of this study was to provide up-to-date random-effects meta-analyses of studies which compare resting-state measures of HRV between unmedicated adults with MD and controls. Database search considered English and German literature to July 2018.

RESULTS

A total of 21 studies including 2250 patients and 1982 controls were extracted. Significant differences between patients and controls were found for (i) frequency domains such as HF-HRV [Hedges' g = -0.318; 95% CI (-0.388 to -0.247)], LF-HRV (Hedges' g = -0.195; 95% CI (-0.332 to -0.059)], LF/HF-HRV (Hedges' g = 0.195; 95% CI (0.086-0.303)] and VLF-HRV (Hedges' g = -0.096; 95% CI (-0.179 to -0.013)), and for (ii) time-domains such as IBI (Hedges' g = -0.163; 95% CI (-0.304 to -0.022)], RMSSD (Hedges' g = -0.462; 95% CI (-0.612 to -0.312)] and SDNN (Hedges' g = -0.266; 95% CI (-0.431 to -0.100)].

CONCLUSIONS

Our findings demonstrate that all HRV-measures were lower in MD than in healthy controls and thus strengthens evidence for lower HRV as a potential cardiovascular risk factor in these patients.

Contribution of DNA methylation in chronic stress-induced cardiac remodeling and arrhythmias in mice

It is recognized that stress can induce cardiac dysfunction, but the underlying mechanisms are not well understood. The present study aimed to test the hypothesis that chronic negative stress leads to alterations in DNA methylation of certain cardiac genes, which in turn contribute to pathologic remodeling of the heart. We found that mice that were exposed to chronic restraint stress (CRS) for 4 wk exhibited cardiac remodeling toward heart failure, as characterized by ventricular chamber dilatation, wall thinning, and decreased contractility. CRS also induced cardiac arrhythmias, including intermittent sinus tachycardia and bradycardia, frequent premature ventricular contraction, and sporadic atrioventricular conduction block. Circulating levels of stress hormones were elevated, and the cardiac expression of tyrosine hydroxylase, a marker of sympathetic innervation, was increased in CRS mice. Using reduced representation bisulfite sequencing, we found that although CRS did not lead to global changes in DNA methylation in the murine heart, it nevertheless altered methylation at specific genes that are associated with the dilated cardiomyopathy (DCM) (e.g., desmin) and adrenergic signaling of cardiomyocytes (ASPC) (e.g., adrenergic receptor-α1) pathways. We conclude that CRS induces cardiac remodeling and arrhythmias, potentially through altered methylation of myocardial genes associated with the DCM and ASPC pathways.-Zhang, P., Li, T., Liu, Y.-Q., Zhang, H., Xue, S.-M., Li, G., Cheng, H.-Y.M., Cao, J.-M. Contribution of DNA methylation in chronic stress-induced cardiac remodeling and arrhythmias in mice.

Psychological Distress and Risk of Myocardial Infarction and Stroke in the 45 and Up Study

Background The interplay between mental and physical health remains poorly understood. We investigated whether psychological distress is associated with risk of myocardial infarction (MI) and stroke in a population-based prospective study. Methods and Results We included participants without prior stroke/MI from the New South Wales 45 and Up Study. We categorized baseline psychological distress as low, medium, and high/very high on the 10-item Kessler Psychological Distress scale and identified stroke and MI through linkage to hospital admission and mortality records. We obtained sex and age-stratified adjusted and unadjusted hazard ratios for the association between psychological distress and MI and stroke. We investigated for interaction between psychological distress and each of age and sex. Among 221 677 participants, 16.2% and 7.3% had moderate and high/very high psychological distress at recruitment, respectively. During 4.7 (±0.98 SD) years of follow-up, 4573 MIs and 2421 strokes occurred. Absolute risk of MI and stroke increased with increasing psychological distress level. In men aged 45 to 79 years, high/very high versus low psychological distress was associated with a 30% increased risk of MI (fully adjusted hazard ratios, 1.30; 95% CI, 1.12-1.51), with weaker estimates in those aged ≥80 years. Among women, high/very high psychological distress was associated with an 18% increased risk of MI (adjusted hazard ratio, 1.18; 95% CI, 0.99-1.42) with similar findings across age groups. In the age group of participants aged 45 to 79 years, high/very high psychological distress and male sex had a supra-additive effect on MI risk. Similar estimates were observed for stroke, with high/very high psychological distress associated with a 24% and 44% increased stroke risk in men and women, respectively, with no evidence of interaction with age or sex. Conclusions Psychological distress has a strong, dose-dependent, positive association with MI and stroke in men and women, despite adjustment for a wide range of confounders.

The role of gender and anxiety in the association between somatic diseases and depression: findings from three combined epidemiological studies in primary care

AIMS

Although associations between various somatic diseases and depression are well established, findings concerning the role of gender and anxiety disorders for these associations remain fragmented and partly inconsistent. Combining data from three large-scaled epidemiological studies in primary care, we aim to investigate interactions of somatic diseases with gender and anxiety disorders in the association with depression.

METHODS

Self-reported depression according to the International Classification of Diseases, Tenth Edition (ICD-10) was assessed in n = 83 737 patients from three independent studies [DETECT (Diabetes Cardiovascular Risk Evaluation: Targets and Essential Data for Commitment of Treatment), Depression-2000 and Generalized Anxiety and Depression in Primary Care (GAD-P)] using the Depression Screening Questionnaire (DSQ). Diagnoses of depression, anxiety disorders and somatic diseases were obtained from treating physicians via standardised clinical appraisal forms.

RESULTS

In logistic regressions, adjusted for gender, age group and study, each somatic disease except for arterial hypertension and endocrine diseases was associated with self-reported depression (odds ratio, OR 1.3-2.6) and each somatic disease was associated with physician-diagnosed depression (OR 1.1-2.4). Most of these associations remained significant after additional adjustment for anxiety disorders and other somatic diseases. The associations with depression increased with a higher number of somatic diseases. Cardiovascular diseases (OR 0.8), diabetes mellitus (OR 0.8) and neurological diseases (OR 0.8) interacted with gender in the association with self-reported depression, while endocrine diseases (OR 0.8) interacted with gender in the association with physician-diagnosed depression. That is, the associations between respective somatic diseases and depression were less pronounced in females v. males. Moreover, cardiovascular diseases (OR 0.7), arterial hypertension (OR 0.8), gastrointestinal diseases (OR 0.7) and neurological diseases (OR 0.6) interacted with anxiety disorders in the association with self-reported depression, and each somatic disease interacted with anxiety disorders in the association with physician-diagnosed depression (OR 0.6-0.8). That is, the associations between respective somatic diseases and depression were less pronounced in patients with v. without anxiety disorders; arterial hypertension was negatively associated with self-reported depression only in patients with anxiety disorders, but not in patients without anxiety disorders.

CONCLUSIONS

A range of somatic diseases as well as anxiety disorders are linked to depression - and especially patients with co-/multi-morbidity are affected. However, interactions with gender and anxiety disorders are noteworthy and of relevance to potentially improve recognition and treatment of depression by physicians. Somatic diseases are associated more strongly with depression in males v. females as well as in patients without v. with anxiety disorders, primarily because women and patients with anxiety disorders per se are characterised by considerably increased depression prevalence that only marginally changes in the presence of somatic comorbidity.

CYP2C19 genotype, physician prescribing pattern, and risk for long QT on serotonin selective reuptake inhibitors

Aim: To examine the impact of CYP2C19 genotype on selective serotonin reuptake inhibitor (SSRI) prescribing patterns. Patients & methods: Observational cohort containing 507 unique individuals receiving an SSRI prescription with CYP2C19 genotype already in their electronic medical record. Genotype was distributed as follows: n = 360 (71%) had no loss of function alleles, 136 (26.8%) had one loss of function allele and 11 (2.2%) had two loss of function alleles. Results & conclusion: For poor metabolizers exposed to sertraline, citalopram or escitalopram, providers changed prescribing patterns in response to alerts in the electronic medical record by either changing the drug, changing the dose or monitoring serial EKGs longitudinally. For intermediate metabolizers exposed to sertraline, citalopram or escitalopram, no alert was needed (mean QTc = 440.338 ms [SD = 31.1273] for CYP2C19*1/*1, mean QTc = 440.371 ms [SD = 29.2706] for CYP2C19*1/*2; p = 0.995).

The Presence of a Psychiatric Condition is Associated With Undergoing Hip Arthroscopy for Femoroacetabular Impingement: A Matched Case-Controlled Study

BACKGROUND

We sought to examine the association between having a psychiatric condition and undergoing hip arthroscopy for femoroacetabular impingement (FAI).

METHODS

A matched case-control study was performed to control for age and gender. All patients over 16 years of age with FAI treated with hip arthroscopy by a single surgeon were randomly matched to a patient of the same age and gender undergoing knee arthroscopy for any diagnosis other than infection by the same surgeon during the same period. Conditional logistic regression was used to compare the odds of having a psychiatric condition between groups.

RESULTS

Fifty-one matched pairs of patients undergoing hip and knee arthroscopy were identified. Each group contained 35 females (69%) and had a mean age of 33.6 years. Of the 51 hip arthroscopy cases, 23 (45.1%) had a psychiatric condition. Of the 51 knee arthroscopy controls, 11 (21.6%) had a psychiatric condition. Patients undergoing hip arthroscopy were statistically significantly more likely to have a psychiatric condition compared to patients undergoing knee arthroscopy with an odds ratio of 3.4 (95% confidence interval 1.3-9.2, P < .01).

CONCLUSION

There was a strong association between having a psychiatric condition and undergoing hip arthroscopy for FAI. More research should be done investigating psychiatric conditions among patients with FAI and whether this association can identify strategies to optimize patient outcomes.

[Genetic comorbidity of depression and somatic disorders]

The aim of our review was to evaluate the perspectives of new therapeutic approaches in comorbid depressive and somatic disorders based on common pathological mechanisms and their genetic risk factors. Literature analysis showed that depression was a complex heterogeneous condition associated with significant prevalence of metabolic, cardiovascular and immune disturbances. The understanding of common molecular mechanisms of risks and course of abovementioned disorders could provide a new strategy for early diagnosis and therapeutic optimization and give the opportunity of 'targeted' approach to different pathological elements.

Fluoxetine oral treatment discloses 5-HT1D receptor as vagoinhibitor of the cardiac cholinergic neurotransmission in rat

Although depression and cardiovascular diseases are related, the role of antidepressants such as fluoxetine (increasing serotonin levels) within cardiac regulation remains unclear. We aimed to determine whether fluoxetine modifies the pharmacological profile of serotonergic influence on vagal cardiac outflow. Rats were treated with fluoxetine (10 mg/kg per day; p.o.) for 14 days or equivalent volumes of drinking water (control group); then, they were pithed and prepared for vagal stimulation. Bradycardic responses were obtained by electrical stimulation of the vagal fibers (3, 6, and 9 Hz) or i.v. acetylcholine (ACh; 1, 5, and 10 μg/kg). The i.v. administration of 5-hydroxytryptamine (5-HT; 10 and 50 μg/kg) inhibited the vagally induced bradycardia. 5-CT (5-HT1/7 agonist) and L-694,247 (5-HT1D agonist) mimicked the serotonin inhibitory effect while α-methyl-5-HT (5-HT2 agonist) was devoid of any action. SB269970 (5-HT7 antagonist) did not abolish 5-CT inhibitory action on the electrically induced bradycardia. Pretreatment with LY310762 (5-HT1D antagonist) blocked the effects induced by L-694,247 and 5-CT. 5-HT and 5-CT failed to modify the bradycardia induced by exogenous ACh. Our outcomes suggest that fluoxetine treatment modifies 5-HT modulation on heart parasympathetic neurotransmission in rats, evoking inhibition of the bradycardia via prejunctional 5-HT1D in pithed rats.

Associations between untreated depression and secondary health care utilization in patients with hypertension and/or diabetes

PURPOSE

We determined the prevalence of untreated depression in patients with hypertension (HT) and/or diabetes (DM) and estimated the extra health care use and expenditures associated with this comorbidity in a rural Hungarian adult population. We also assessed the potential workload of systematic screening for depression in this patient group.

METHODS

General health check database from a primary care programme containing survey data of 2027 patients with HT and/or DM was linked to the outpatient secondary care use database of National Institute of Health Insurance Fund Management. Depression was ascertained by Beck Depression Inventory score and antidepressant drug use. The association between untreated depression and secondary healthcare utilization indicated by number of visits and expenses was evaluated by multiple logistic regression analysis controlled for socioeconomic/lifestyle factors and comorbidity. The age-, sex- and education-specific observations were used to estimate the screening workload for an average general medical practice.

RESULTS

The frequency of untreated depression was 27.08%. The untreated severe depression (7.45%) was associated with increased number of visits (OR 1.60, 95% CI 1.11-2.31) and related expenses (OR 2.20, 95% CI 1.50-3.22) in a socioeconomic status-independent manner. To identify untreated depression cases among patients with HT and/or DM, an average GP has to screen 42 subjects a month.

CONCLUSION

It seems to be reasonable and feasible to screen for depression in patients with HT and/or DM in the primary care, in order to detect cases without treatment (which may be associated with increase of secondary care visits and expenditures) and to initiate the adequate treatment of them.

Self-disgust as a potential mechanism explaining the association between loneliness and depression

BACKGROUND

Loneliness and self-disgust have been considered as independent predictors of depressive symptoms. In the present study, we hypothesized that self-disgust can explain the association between loneliness and depression, and that emotion regulation strategies interact with self-disgust in predicting depressive symptoms.

METHODS

Three hundred and seventeen participants (M = 29.29 years, SD = 14.11; 76.9% females) completed structured anonymous self-reported measures of loneliness, self-disgust, emotion regulation strategies, and depressive symptoms.

RESULTS

One-way MANOVA showed that participants in the high-loneliness group reported significantly higher behavioural and physical self-disgust, compared to those in the middle and low-loneliness groups. Bootstrapped hierarchical linear regression analysis showed that self-disgust significantly improved predicted variance in depressive symptoms, after controlling for the effects of loneliness. Regression-based mediation modelling showed that both physical and behavioural self-disgust significantly mediated the association between loneliness and depression. Finally, moderated regression analysis showed that expressive suppression interacted with self-disgust in predicting depressive symptoms.

LIMITATIONS

A cross-sectional design was used, and our study focused on expressive suppression and cognitive reappraisal but not on other aspects of emotion regulation or the modulation of emotional arousal and responses.

CONCLUSIONS

We demonstrated, for the first time, that self-disgust plays an important role in the association between loneliness and depressive symptoms. Furthermore, variations in emotion regulation strategies can explain the association between self-disgust and depressive symptoms.

Cardiometabolic risks in PCOS: a review of the current state of knowledge

INTRODUCTION

Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting up to 18% women of reproductive age. It is associated with a range of metabolic, reproductive, and psychological features. Current evidence indicates a role of PCOS in the development of metabolic and increased cardiovascular risk factors (CVRF) with implications for compromised cardiovascular endpoint disease, which may have a considerable impact on health and health care costs.

AREAS COVERED

Existing studies examining long-term cardiometabolic health in PCOS are heterogeneous with inconsistent findings. In the current review, we aim to explore and critically review retrospective, prospective, meta-analysis and review articles relating to PCOS on cardiometabolic risk factors and clinical consequences to summarize the evidence, note evidence gaps, and suggest implications for future research.

EXPERT COMMENTARY

Although there is an established association between PCOS and metabolic health, implications on cardiac health are more uncertain with associations observed for CVRF and subclinical disease, yet limited and conflicting data on actual cardiovascular endpoints. There is a lack of population-based long-term studies examining cardiometabolic morbidity and mortality in PCOS with a need for further research to progress toward a better understanding of the long-term cardiometabolic impacts in women with PCOS.

Impact of psychiatric comorbidity on the severity, short-term functional outcome, and psychiatric complications after acute stroke

BACKGROUND AND PURPOSE

The comorbidity of psychiatric disorders and cerebrovascular disease appears to be complex with underlying bidirectional influences. Hitherto, research has focused mainly on the evaluation of stroke risk in particular psychiatric disorders; only a few studies have assessed their role in the acute natural history of stroke. The aim of this study was to provide a perspective on psychiatric premorbidity and its impact on stroke severity, psychiatric complications during the initial treatment phase, and the short-term functional outcome of stroke.

PATIENTS AND METHODS

We retrospectively studied the impact of a predocumented psychiatric diagnosis (PDPD) on stroke severity, short-term functional outcome, and psychiatric complications in a sample of 798 patients consecutively admitted for acute ischemic or hemorrhagic stroke by performing a chart review. Group comparisons (PDPD vs non-PDPD) with adjustment for covariates were carried out either using multivariate analysis of variance or logistic regression analysis.

RESULTS

More severe strokes (ie, mean National Institute of Health Stroke Scale score on admission 10.1±7.9 vs 7.5±7.4; F(10,796)=18.5, p<0.0001) and higher prevalence of poor outcome (73.7 vs 54.9%; OR: 2.6, standard error: 0.5, z=4.82, p<0.0001) was found in patients with a documented psychiatric diagnosis at the time of stroke, as well as a higher rate of psychiatric complications during the initial treatment phase (46.7 vs 28.9%; OR: -0.78, z=4.59, p<0.0001).

CONCLUSION

Our data have clinical implications in that they call for identification of psychiatric premorbidity or comorbidity through careful history-taking and particularly close monitoring for psychiatric complications with respect to their potentially negative impact on outcome after stroke.

Heart rate variability and incidence of depression during the first six months following first myocardial infarction

BACKGROUND

Post-myocardial depression is a highly prevalent condition worsening the course and prognosis of coronary artery disease. One of the possible pathogenetic factors is dysregulation of the autonomous nervous system, resulting in heart rate variability reduction.

METHODS

Twenty two patients hospitalised due to a first myocardial infarction were included. The Beck Depression Inventory (BDI) was used to rate the severity of their depressive symptoms.

RESULTS

Depressive symptomatology, defined as BDI ≥10, was present in 36.3% of the patients. Increase in heart rate variability (HRV) was observed in both groups during the first 6 months after the myocardial infarction. The HRV was significantly lower in the depressed group compared to patients without depression.

CONCLUSION

Presence of depression after the myocardial infarction (MI) is associated with a significant decrease of the time domain HRV measure SDNN (standard deviation of all normal RR intervals) and with its slower increase during at least a three months period.

Impact of Physical Activity and Sleep Duration on Depressive Symptoms in Hypertensive Patients: Results from a Nationally Representative Korean Sample

Depressive symptoms among individuals with hypertension may increase the risk of cardio-cerebrovascular disease, disease burden, and mortality. However, few studies have examined the relationships among physical activity, sleep duration, and depressive symptoms. Thus, this cross-sectional study examined the associations of physical activity and sleep duration with depressive symptoms in individuals with hypertension. We analyzed data collected as part of the 2014 Korea National Health and Nutrition Examination Survey, which included 846 patients with hypertension aged 19 or older. The prevalence rate of depressive symptoms was around 11.2%. A logistic regression analysis showed that moderate to vigorous physical activity (odds ratio (OR) = 4.42; 95% confidence interval (CI) = 2.19–8.89) and short (OR = 2.18; 95% CI = 1.11–4.28) and long sleep duration (OR = 4.09; 95% CI = 1.83–9.13) increased the risk of depressive symptoms after adjusting for confounding factors. Additionally, older age and low educational levels were associated with depressive symptoms. Our findings highlight that physical activity and sleep duration should be key components of lifestyle modification among hypertensive patients with depressive symptoms. Further investigation might benefit from validating these findings using a longitudinal design and examining the mediating effects of physical activity and/or sleep duration on the relationship between individual characteristics and depressive symptoms.

Depression, antidepressants, and the risk of non-valvular atrial fibrillation: A nationwide Danish matched cohort study

Background

Depression is associated with an increased risk of a series of cardiovascular diseases and with increased symptom burden in patients with atrial fibrillation. The aim of this study was to determine the association between depression as well as antidepressant treatment and the risk of incident atrial fibrillation.

Design

A nationwide register-based study comparing the atrial fibrillation risk in all Danes initiating antidepressant treatment from 2000 to 2013 ( N = 785,254) with that in a 1:5-matched sample from the general population.

Methods

Cox regression was used to estimate adjusted hazard ratios (aHRs) and associated 95% confidence intervals (95% CIs), both after initiation of treatment and in the month before when patients were assumed to have medically untreated depression.

Results

Antidepressant treatment was associated with a three-fold higher risk of atrial fibrillation during the first month (aHR = 3.18 (95% CI: 2.98–3.39)). This association gradually attenuated over the following year (aHR = 1.37 (95% CI: 1.31–1.44) 2–6 months after antidepressant therapy initiation, and aHR = 1.11 (95% CI: 1.06–1.16) 6–12 months after). However, the associated atrial fibrillation risk was even higher in the month before starting antidepressant treatment (aHR = 7.65 (95% CI: 7.05–8.30) from 30 to 15 days before, and aHR = 4.29 (95% CI: 3.94–4.67) the last 15 days before). Overall, 0.4% of patients were diagnosed with atrial fibrillation from 30 days before to 30 days after antidepressant treatment.

Conclusions

Antidepressant users had a substantially increased atrial fibrillation risk, particularly before treatment initiation. Whether this mirrors a causal relation between depression and atrial fibrillation may have large consequences for public health and should be discussed.

Impact of Psychiatric Comorbidities on Short-Term Outcomes Following Intervention for Lumbar Degenerative Disc Disease

STUDY DESIGN

Retrospective, observational cohort study.

OBJECTIVE

To investigate the impact of psychiatric diseases on short-term outcomes in patients undergoing fusion surgery for lumbar degenerative disc disease (LDDD).

SUMMARY OF BACKGROUND DATA

Limited literature exists on the prevalence and impact of psychiatric comorbidities on outcomes in patients undergoing surgery for LDDD.

METHODS

Adult patients (>18 yr) registered in the Nationwide Inpatient Sample database (2002-2011) and undergoing an elective spine fusion for LDDD that met inclusion criteria formed the study population. Defined primary outcome measures were discharge disposition, length of stay, hospitalization cost, and short-term postsurgical complications (neurological, respiratory, cardiac, gastrointestinal, wound complication and infections, venous thromboembolism, and acute renal failure). Multivariable regression techniques were used to explore the association of psychiatric comorbidities on short-term outcomes by adjusting for patient demographics, clinical, and hospital characteristics.

RESULTS

Of the 126,044 adult patients undergoing fusion surgery for LDDD (mean age: 54.91 yr, 58% female) approximately 18% had a psychiatric disease. Multivariable regression analysis revealed patients with psychiatric disease undergoing fusion surgery have higher likelihood for unfavorable discharge (odds ratio [OR] 1.41; 95% confidence interval [CI] 1.35-1.47; P < 0.001), length of stay (OR 1.03; 95% CI 1.02-1.04; P < 0001), postsurgery neurologic complications (OR 1.25; 95% CI 1.13-1.37; P < 0.001), venous thromboembolic events (OR 1.38 95% CI 1.26-1.52; P < 0.001), and acute renal failure (OR 1.17; 95% CI 1.01-1.37; P = 0.040). Patients with psychiatric disease were also associated to have higher hospitalization cost (6.3% higher; 95% CI: 5.6%-7.1%; P < 0.001) compared to those without it.

CONCLUSION

Our study quantifies the estimates for presence of concomitant psychiatric comorbid conditions on short outcomes in patients undergoing fusions for LDDD. The data provide supporting evidence for adequate preoperative planning and postsurgical care including consultation for mental health for favorable outcomes.

Prevalence of Anxiety and Depression Symptoms in Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries

BACKGROUND

Myocardial infarction with non-obstructive coronary arteries is a working diagnosis for several heart disorders. Previous studies on anxiety and depression in patients with myocardial infarction with non-obstructive coronary arteries are lacking. Our aim was to investigate the prevalence of anxiety and depression among patients with myocardial infarction with non-obstructive coronary arteries.

METHODS

We included 99 patients with myocardial infarction with non-obstructive coronary arteries together with age- and sex-matched control groups who completed the Beck Depression Inventory and the Hospital Anxiety and Depression Scale (HADS) 3 months after the acute event.

RESULTS

Using the Beck Depression Inventory, we found that the prevalence of depression in patients with myocardial infarction with non-obstructive coronary arteries (35%) was higher than in healthy controls (9%; P = .006) and similar to that of patients with coronary heart disease (30%; P = .954). Using the HADS anxiety subscale, we found that the prevalence of anxiety in patients with myocardial infarction with non-obstructive coronary arteries (27%) was higher than in healthy controls (9%; P = .002) and similar to that of patients with coronary heart disease (21%; P = .409). Using the HADS depression subscale, we found that the prevalence of depression in patients with myocardial infarction with non-obstructive coronary arteries (17%) was higher than in healthy controls (4%; P = .003) and similar to that of patients with coronary heart disease (13%; P = .466). Patients with myocardial infarction with non-obstructive coronary arteries and takotsubo syndrome scored higher on the HADS anxiety subscale than those without (P = .028).

CONCLUSIONS

This is the first study on the mental health of patients with myocardial infarction with non-obstructive coronary arteries to show that prevalence rates of anxiety and depression are similar to those in patients with coronary heart disease.

Arab Men and Women's Conceptualization of Mental Health and Depression: A Qualitative Study from the Middle East

Cardiovascular diseases are the leading cause of death worldwide. Among cardiovascular patients, depression is associated with an increased morbidity and mortality. Understanding how depression is conceptualized from cardiovascular patients' perspective can help with prevention, early detection, and treatment for depression. This might reduce cardiovascular morbidity and mortality, and save health care costs. To the best of our knowledge, there is no study in the Gulf region exploring depression among Arab cardiovascular patients. The purpose of this exploratory ethnographic qualitative research is to investigate how Arab male and female patients with cardiovascular disease conceptualize mental health and depression. Two theoretical frameworks guided this research: (1) The Ecological Perspective, and (2) Kleinman's Explanatory Model of Health and Illness. Using maximum variation purposive sampling, thirty (30) male and twenty-five (25) female, self-identified, Arab cardiovascular patients were recruited as research participants. Individual in-depth interviews were conducted using a semi-structured questionnaire. Thematic analysis was performed to generate themes. Nvivo 10, a qualitative data analysis software, was used to organize the narrative data. The participants in this study placed great emphasis on the manifestations of mental illness and their impact on both themselves and their families. Four major themes were identified from their narratives: psychological and physical disturbances; unfavorable personal characteristics; work issues and financial constraints; lack of family and social support. The knowledge generated in this study might help increase awareness, prevention of and treatment for depression among cardiovascular patients in Qatar. The findings from this study can also be used to inform a multi-disciplinary and multi-sectoral intervention approach that is contextualized to meet the mental health care needs of Arab cardiovascular patients, thus reducing cardiovascular diseases morbidity and mortality in Qatar and the Gulf region.

The clinical role of well-being therapy

PURPOSE

There are several clinical areas where psychological well-being may play an important role: the assessment of the dynamic balance between ill-being and well-being; reduction of incidence, prevention of recurrence and achievement of full recovery in psychiatric disorders such as depression; patient's satisfaction and perceived change after treatment. The aim of this article is to discuss the clinical role of Well-Being Therapy (WBT).

MATERIALS AND METHODS

A critical review of the literature concerned with psychological well-being and its treatment was performed. WBT is a short-term psychotherapeutic strategy that emphasizes self-observation of psychological well-being, with the use of a structured diary, cognitive restructuring of interfering thoughts and/or behaviors through cognitive behavioral techniques, and homework assignments (i.e. pursuing optimal experiences). WBT is based on a multidimensional model of psychological well-being that was originally developed by Marie Jahoda and it is aimed at achieving a state of euthymia.

RESULTS

WBT has been validated in a number of randomized controlled trials. The sequential combination of cognitive behavior therapy (CBT) and WBT has mainly characterized its use so far. Illustration of a clinical case exemplifies its application and the potential role of psychological well-being in the clinical process.

CONCLUSIONS

Even though more randomized controlled trials concerned with WBT are needed, consideration of psychological well-being may unravel innovative approaches to the prevention, assessment and treatment of mood and anxiety disorders.

The Mortality and Myocardial Effects of Antidepressants Are Moderated by Preexisting Cardiovascular Disease: A Meta-Analysis

BACKGROUND

Antidepressants (ADs) are commonly prescribed medications, but their long-term health effects are debated. ADs disrupt multiple adaptive processes regulated by evolutionarily ancient biochemicals, potentially increasing mortality. However, many ADs also have anticlotting properties that can be efficacious in treating cardiovascular disease. We conducted a meta-analysis assessing the effects of ADs on all-cause mortality and cardiovascular events in general-population and cardiovascular-patient samples.

METHODS

Two reviewers independently assessed articles from PubMed, EMBASE, and Google Scholar for AD-related mortality controlling for depression and other comorbidities. From these articles, we extracted information about cardiovascular events, cardiovascular risk status, and AD class. We conducted mixed-effect meta-analyses testing sample type and AD class as moderators of all-cause mortality and new cardiovascular events.

RESULTS

Seventeen studies met our search criteria. Sample type consistently moderated health risks. In general-population samples, AD use increased the risks of mortality (HR = 1.33, 95% CI: 1.14-1.55) and new cardiovascular events (HR = 1.14, 95% CI: 1.08-1.21). In cardiovascular patients, AD use did not significantly affect risks. AD class also moderated mortality, but the serotonin reuptake inhibitors were not significantly different from tricyclic ADs (TCAs) (HR = 1.10, 95% CI: 0.93-1.31, p = 0.27). Only "other ADs" were differentiable from TCAs (HR = 1.35, 95% CI: 1.08-1.69). Mortality risk estimates increased when we analyzed the subset of studies controlling for premedication depression, suggesting the absence of confounding by indication.

CONCLUSIONS

The results support the hypothesis that ADs are harmful in the general population but less harmful in cardiovascular patients.

Objective detection of chronic stress using physiological parameters

The aim of this study was to design a system to diagnose chronic stress, based on blunted reactivity of the autonomic nervous system (ANS) to cognitive load (CL). The system concurrently measures CL-induced variations in pupil diameter (PD), heart rate (HR), pulse wave amplitude (PWA), galvanic skin response (GSR), and breathing rate (BR). Measurements were recorded from 58 volunteers whose stress level was identified using the State-Trait Anxiety Inventory. Number-multiplication questions were used as CLs. HR, PWA, GSR, and PD were significantly (p < 0.05) changed during CL. CL-induced changes in PWA (16.87 ± 21.39), GSR (- 13.71 ± 7.86), and PD (11.56 ± 9.85) for non-stressed subjects (n = 36) were significantly different (p < 0.05) from those in PWA (2.92 ± 12.89), GSR (- 6.87 ± 9.54), and PD (4.51 ± 10.94) for stressed subjects (n = 22). ROC analysis for PWA, GSR, and PD illustrated their usefulness to identify stressed subjects. By inputting all features to different classification algorithms, up to 91.7% of sensitivity and 89.7% of accuracy to identify stressed subjects were achieved using 10-fold cross-validation. This study was the first to document blunted CL-induced changes in PWA, GSR, and PD in stressed subjects, compared to those in non-stressed subjects. Preliminary results demonstrated the ability of our system to objectively detect chronic stress with good accuracy, suggesting the potential for monitoring stress to prevent dangerous stress-related diseases. Graphical abstract Chronic stress degrads the autonomic nervous system reaction to cognitive loads. Measurement of reduced changes in physiological signals during asking math questions was useful to identify people with high STAI score (stressed subjects).

Depression Screening in Cardiac Surgery Patients

BACKGROUND

Depression is common in patients with ischaemic heart disease and preoperative depression is a risk factor following coronary artery bypass grafting. The American Heart Association recommends depression screening in all patients with heart disease. Our aim was to assess the feasibility and results of a depression screening program in cardiac surgery patients.

METHODS

We introduced a depression screening project at the cardiac surgery department at Karolinska University Hospital and included patients between 2013 and 2016. Patients scheduled for elective surgery recieved the Patient Health Questionnaire (PHQ-9), a depression screening instrument, by mail approximately 2weeks before surgery. Urgent patients recieved the PHQ-9 on the ward. Baseline characteristics, medical history, and medications were collected from patient charts, and entered into a study database together with the results from the PHQ-9 questionaires.

RESULTS

During the study period, 2,512 patients underwent cardiac sugery; 1,133 (45%) completed PHQ-9. The response-rate in patients scheduled for elective surgery was 64%, and 15% in urgent patients. Fifteen per cent (15%) had a PHQ-9 score ≥10 suggestive of major depression. Reporting a PHQ-9 score ≥10 was twice as common in women as in men (23% vs 12%).

CONCLUSIONS

Systematic depression screening using PHQ-9 in cardiac surgery patients was feasible and not very resource-intensive. The project showed a satisfactory response-rate in elective patients, but adjustments to increase the response-rate in urgent patients are needed. Future studies should investigate if and how patients with symptoms of depression would benefit from depression management.

Impact of Psychiatric Illness on Outcomes After Operatively Managed Tibial Plateau Fractures (OTA-41)

OBJECTIVES

To assess the role self-reported treatment for a psychiatric diagnosis may play in long-term functional outcomes after operatively managed tibial plateau fractures.

DESIGN

Prospective cohort study.

SETTING

Academic medical center.

PATIENTS

Over an 11-year period, patients were screened and identified on presentation to the emergency department or in the clinical office for inclusion in an IRB-approved registry. A total of 245 patients were included in the study. Twenty-one patients reported treatment for a psychiatric diagnosis.

INTERVENTION

Surgical repair of tibial plateau fractures.

MAIN OUTCOME MEASURE

Patients were divided into 2 cohorts; 1 cohort being those who self-reported receiving treatment of a psychiatric diagnosis (PI); the other group being those who did not self-report receiving treatment of a psychiatric diagnosis (NPI). Three-month, 6-month, and long-term outcomes (mean = 18 months) were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, and postoperative complications (infection, VTE, nonunion, and necessity for secondary operations).

RESULTS

Pain scores were higher in patients who self-reported receiving treatment for a psychiatric diagnosis (P = 0.012). Long-term functional outcomes as measured by the SFMA were demonstrated to be worse in patients who self-reported treatment for a psychiatric diagnosis (P = 0.034). No differences existed between groups in regards to postoperative complications. Multiple linear regression analysis revealed that being treated for diagnosis of a mental health illness was an independent predictor of worse functional outcomes at long-term follow-up [B = 8.874, 95% confidence interval (CI) = 0.354-17.394, P = 0.041].

CONCLUSIONS

Mental health plays a crucial role in long-term outcomes after operative fixation of tibial plateau fractures. Patients who have been diagnosed with a mental health illness have significantly worse outcomes at long-term follow-up.

Dual Diagnosis and Total Hip Arthroplasty

The co-occurrence of a mental illness and a substance abuse disorder (SUD) is common and has been referred to as a "dual diagnosis" (DD). Although studies have independently investigated mental illness alone and SUD alone, few have examined the effects of these entities combined on complications. A search of the Medicare database from 2005 to 2012 identified 2000 DD patients who underwent total hip arthroplasty (THA). They were compared with 86,976 patients with mental illness only and 590,689 controls (no mental illness or SUD). Medical comorbidities and postoperative complications at 30-day, 90-day, and minimum 2-year time points were analyzed. There was a significant increase (P<.001) in 7 (53.8%) of 13 recorded postoperative medical complications, including acute renal failure (odds ratio [OR], 1.78), postoperative anemia (OR, 1.31), and blood transfusion (OR, 1.24), at the 90-day time point. In addition, there was a statistically significant increase overall in periprosthetic infection (periprosthetic joint infection OR, 4.30; P<.001), periprosthetic fracture (OR, 2.80; P<.001), dislocation (OR, 6.38; P<.001), and the need for THA revision (OR, 3.58; P<.001). When compared with patients with mental illness only, DD patients remained at significantly (P<.001) increased risk for 90-day and overall postoperative surgical complications, including dislocation, periprosthetic joint infection, and THA revision. Patients with a DD were at significant risk for perioperative complications compared with both control patients and patients with mental illness only. Studies investigating only psychiatric disease or only SUD may miss a vulnerable cohort. Further investigation is needed to exactly define to what extent DD amplifies complication rates.

The Adverse Effects of Environmental Noise Exposure on Oxidative Stress and Cardiovascular Risk

Epidemiological studies have provided evidence that traffic noise exposure is linked to cardiovascular diseases such as arterial hypertension, myocardial infarction, and stroke. Noise is a nonspecific stressor that activates the autonomous nervous system and endocrine signaling. According to the noise reaction model introduced by Babisch and colleagues, chronic low levels of noise can cause so-called nonauditory effects, such as disturbances of activity, sleep, and communication, which can trigger a number of emotional responses, including annoyance and subsequent stress. Chronic stress in turn is associated with cardiovascular risk factors, comprising increased blood pressure and dyslipidemia, increased blood viscosity and blood glucose, and activation of blood clotting factors, in animal models and humans. Persistent chronic noise exposure increases the risk of cardiometabolic diseases, including arterial hypertension, coronary artery disease, diabetes mellitus type 2, and stroke. Recently, we demonstrated that aircraft noise exposure during nighttime can induce endothelial dysfunction in healthy subjects and is even more pronounced in coronary artery disease patients. Importantly, impaired endothelial function was ameliorated by acute oral treatment with the antioxidant vitamin C, suggesting that excessive production of reactive oxygen species contributes to this phenomenon. More recently, we introduced a novel animal model of aircraft noise exposure characterizing the underlying molecular mechanisms leading to noise-dependent adverse oxidative stress-related effects on the vasculature. With the present review, we want to provide an overview of epidemiological, translational clinical, and preclinical noise research addressing the nonauditory, adverse effects of noise exposure with focus on oxidative stress.

Pre-existing depression predicts survival in cardiovascular disease and cancer

Background

Previous studies have found depression to be negatively associated with the prognosis of both cardiovascular disease (CVD) and cancer, but this may partly reflect reverse causality. We limited the possibility of reverse causality by measuring depression before the first diagnosis of CVD or cancer.

Methods

We used an 11% longitudinal random sample of the Finnish population aged 25 years or older who are residents of Finland for at least 1 year between 1987 and 2007, with an 80% oversample of those who died during this period. Those who had their first incidence of coronary heart disease (CHD) (n=107 966), stroke (n=68 685) or cancer (n=113 754) between 1998 and 2012 were followed up for cause-specific mortality from the date of diagnosis until the end of 2012. Depression was defined as having antidepressant purchases two to three calendar years before the incidence. Logistic and Cox regression models were used to examine short-term and long-term mortality by depression status.

Results

Long-term mortality after diagnosis was 1.34 (95% CI 1.25 to 1.44) for CHD, 1.26 (95% CI 1.15 to 1.37) for stroke and 1.10 (95% CI 1.04 to 1.16) for cancer in those who had used antidepressants in two consecutive calendar years as compared with those with no purchases. Short-term mortality from CHD was elevated among persons with depression (OR=1.30; 95% CI 1.06 to 1.61), but no association was found for stroke.

Conclusion

Pre-existing depression is associated with a worse prognosis of CHD, stroke and cancer. More attention in the healthcare system is needed for patients with chronic diseases who have a history of depression.

Loneliness and cardiovascular disease and the role of late-life depression

OBJECTIVE

Loneliness and depression have a strong reciprocal influence, and both predict adverse health outcomes at old age. Therefore, this study examines whether loneliness is associated with the presence of cardiovascular diseases taking into account the role of late-life depression.

METHODS

Cross-sectional data of 477 older adults in the Netherlands Study of Depressed Older Persons were used. Logistic regression analysis was performed to examine the relation between loneliness and cardiovascular disease. Depression was added to the regression model to examine whether depression is an explanatory factor in the association between loneliness and cardiovascular disease. Interaction terms between loneliness and depression and between loneliness and sex were introduced in the regression model to investigate whether depressed and non-depressed participants, and men and women differed in their association between loneliness and cardiovascular disease.

RESULTS

Of the overall group, 61% were lonely, 28% had a history of cardiovascular disease and 74% were depressed. Loneliness and cardiovascular disease were not associated in the overall group after adjustment for confounders (continuous: odds ratio [OR] = 1.04, 95% confidence interval [CI] = 0.98-1.10), p = 0.25; dichotomous: OR = 1.27, 95% CI = 0.80-2.03, p = 0.32). For women, there was an association between loneliness and cardiovascular diseases (continuous: OR = 1.13, 95% CI = 1.06-1.21, p < 0.001; dichotomous: OR = 2.64, 95% CI = 1.50-4.65, p = 0.001), but this association was not present in men (OR = 0.96, 95% CI = 0.88-1.05, p = 0.38). This association remained significant after adjustment for confounders, but it lost significance after adding depression to the model.

CONCLUSION

For women only, there was an association between loneliness and cardiovascular disease. However, this association was explained by depression, indicating that loneliness in its own right seems not related with cardiovascular disease. Copyright © 2017 John Wiley & Sons, Ltd.

Sociodemographic, clinical, and functional long-term outcomes in adolescents and young adults with mental disorders

OBJECTIVE

To examine unfavorable sociodemographic, clinical, and functional long-term outcomes for a range of adolescent mental disorders.

METHODS

A total number of 2210 adolescents and young adults (14-24 years at baseline, T0) from a representative community sample were prospectively followed up (T1-T3) over 10 years. DSM-IV mental disorders, sociodemographic, clinical, and functional outcomes were assessed using the DIA-X/M-CIDI and its embedded assessment modules.

RESULTS

In (multinomial) logistic regressions adjusted for sex, age, other baseline disorders and sociodemographics, baseline anxiety, affective, substance use, somatoform and eating disorders (lifetime) predicted various unfavorable sociodemographic, clinical, and functional outcomes at T3. Particularly, strong associations were found between baseline disorders and adverse clinical outcomes at T3 (12-month diagnosis of the same/other disorder(s), drug use, suicide attempts, and help-seeking due to psychological problems). While substance use disorders were primarily associated with unfavorable sociodemographic and educational outcomes, anxiety and eating disorders were associated with unfavorable interpersonal outcomes, affective disorders with pregnancy-/childbirth-related complications and financial issues, and somatoform disorders with unfavorable educational/occupational and interpersonal outcomes. The risk of unfavorable outcomes increased with clinical severity, especially a higher number of baseline diagnoses.

CONCLUSIONS

Our findings emphasize the importance of effective treatment of mental disorders to prevent unfavorable long-term outcomes in various life domains.

Antidepressants and suicidal behaviour in late life: a prospective population-based study of use patterns in new users aged 75 and above

Purpose

To investigate associations between antidepressant use patterns and risk of fatal and non-fatal suicidal behaviours in older adults who initiated antidepressant therapy.

Method

A national population-based cohort study conducted among Swedish residents aged ≥ 75 years who initiated antidepressant treatment. Patients who filled antidepressant prescriptions between January 1, 2007 and December 31, 2013 (N = 185,225) were followed until December 31, 2014. Sub-hazard ratios of suicides and suicide attempts associated with use patterns of antidepressants, adjusting for potential confounders such as serious depression were calculated using the Fine and Gray regression models.

Results

During follow-up, 295 suicides and 654 suicide attempts occurred. Adjusted sub-hazard ratios (aSHRs) were increased for both outcomes in those who switched to another antidepressant (aSHR for suicide 2.42, 95% confidence interval 1.65 to 3.55, and for attempt 1.76, 1.32 to 2.34). Elevated suicide risks were also observed in those who concomitantly filled anxiolytics (1.54, 1.20 to 1.96) and hypnotics (2.20, 1.69 to 2.85). Similar patterns were observed for the outcome suicide attempt. Decreased risk of attempt was observed among those with concomitant use of anti-dementia drugs (0.40, 0.27 to 0.59).

Conclusion

Switching antidepressants, as well as concomitant use of anxiolytics or hypnotics, may constitute markers of increased risk of suicidal behaviours in those who initiate antidepressant treatment in very late life. Future research should consider indication biases and the clinical characteristics of patients initiating antidepressant therapy.

Baseline Oxidative Stress Is Associated with Memory Changes in Omega-3 Fatty Acid Treated Coronary Artery Disease Patients

Objective

This study investigated whether pretreatment oxidative stress, measured by lipid hydroperoxides (LPH), 4-hydroxy-2-nonenal (4-HNE), 8-isoprostane (8-ISO), and malondialdehyde (MDA), was associated with improvement in immediate recall among n-3 PUFA-treated coronary artery disease patients.

Methods

This was a secondary analysis of the CAROTID trial (NCT00981383). Composite immediate recall, measured using the California Verbal Learning Test, Second Edition, and the Brief Visuospatial Memory Test-Revised, was assessed. LPH, 4-HNE, 8-ISO, MDA, and n-3 PUFA concentrations were analysed from fasting blood. Patients then received either n-3 PUFA treatment or placebo for 12 weeks, after which composite immediate recall was reassessed. Linear regression was used to investigate relationships between lipid peroxidation markers and changes in composite immediate recall in each treatment group.

Results

Eighty-five patients (age = 61.1 ± 8.5, 77% male, mean years of education = 15.3 ± 3.4) were included (n = 46 placebo, n = 39 n-3 PUFA). After adjusting for multiple comparisons and potential confounders, greater baseline concentrations of LPH (β = 0.45, p = .002) and 4-HNE (β = 0.38, p = .005) were associated with greater improvement in composite immediate recall among n-3 PUFA-treated patients. No other associations were observed.

Conclusions

N-3 PUFA treatment may be more likely to improve immediate recall in patients with greater oxidative stress.

Association Between Mental Health Burden and Coronary Artery Disease in U.S. Women Veterans Over 45: A National Cross-Sectional Study

BACKGROUND

The women Veteran population accessing Veterans Health Administration (VA) care has grown rapidly. Women Veterans exhibit high rates of mental health conditions that increase coronary artery disease (CAD) risk; however, the relationship between specific conditions and increasing mental health burden to CAD in this population is unknown.

MATERIALS AND METHODS

Using VA National Patient Care Data for 2009, we identified women Veterans over 45 (N = 157,195). Logistic regression models examined different mental health diagnoses and increasing mental health burden (number of diagnostic clusters) as predictors of CAD.

RESULTS

CAD prevalence was 4.16%, and 36% of women Veterans were current smokers. Depression exhibited the strongest association with CAD (odds ratio [OR] 1.60, 95% confidence interval [CI] [1.50-1.71]), similar to that of current smoking (OR 1.68 [1.58-1.78]). Controlling for demographic variables, smoking, diabetes, and obesity, each additional mental health diagnosis increased the odds of CAD by 44%.

CONCLUSIONS

Women Veterans over age 45 accessing VA care exhibited a high degree of mental health burden, which is associated with elevated odds of CAD; those with depression alone had 60% higher odds of CAD. For women Veterans using VA, mental health diagnoses may act as CAD risk factors that are potentially modifiable. Novel interventions in primary care and mental health are needed to address heart disease in this growing and aging population.

Differences of sympathetic and parasympathetic modulation in major depression

Inconsistent results have been reported with respect to cardiac autonomic function in major depression. The aim of our study was to investigate autonomic function in various branches of the autonomic nervous system in order to better understand parasympathetic and sympathetic modulation in the disease. We investigated 29 unmedicated patients suffering from major depression (MD) in comparison to matched control subjects (gender, age, BMI). The autonomic assessment at rest included values of heart rate variability (HRV), blood pressure variability (BPV), baroreflex sensitivity (BRS), respiration, skin conductance (SC) as well as the calculation of pupillary diameter and the unrest index (PUI). Results were compared by means of a multivariate analysis of variance. In a classification analysis, we identified suitable parameters for patient - control separation. Finally, to analyze interrelations of pupillometric parameters and autonomic indices, we estimated Pearson correlation coefficients and fitted a linear regression model. Apart from a significantly increased heart rate (75±12 vs. 65±6min^-1, p<0.001) and decreased BRS (14±13 vs. 20±15ms/mmHg, p<0.05), we observed a lack of significant differences in HRV and BPV analysis between patients and controls. However, pupillary diameter (left: 4.3±0.9 vs. 3.8±0.6, p<0.01; right: 4.3±0.9 vs. 3.7±0.6mm, p<0.01) and PUI (left: 14.8±6.0 vs. 10.7±4.5mm/min, p<0.01; right: 14.1±5.5 vs. 10.7±4.8mm/min, p<0.01), as well as the level (left: 7.3±6.2 vs. 4.3±4.4 μS, p<0.05) and fluctuations of skin conductance (left: 4.2±4.1 vs. 2.5±3.6, p<0.05; right: 4.2±4.4 vs. 2.6±3.2, p<0.05) were significantly different. The classification accuracy was 88.5% with high specificity (e=92.9%) and sensitivity (s=83.3%) including heart rate, PUI and skin conductance. HRV indices correlated to PUI in controls but not in patients. Our data add evidence to the current debate on autonomic function in major depression. We suggest that diverse results are mainly caused by methodological shortcomings, in particular by the application of HRV assessment only, which misses changes of sympathetic modulation. The application of broader analyzing tools will clarify the pattern of autonomic function in depression and ultimately its role in cardiac morbidity and mortality.

Maternal depression during pregnancy is associated with increased birth weight in term infants

Previous research of maternal depression during pregnancy suggests an association with low birth weight in newborns. Review of these studies reveals predominant comorbidity with premature birth. This current study examines antenatal depression and birth weight in term, medically low-risk pregnancies. Maternal physiological and demographic measures were collected as well. In total, 227 pregnant women were recruited to participate in four experimental protocols at Columbia University Medical Center. Results indicate that depressed pregnant women who carry to term had significantly higher heart rates, lower heart rate variability, and gave birth to heavier babies than those of pregnant women who were not depressed. Low income participants had significantly higher levels of depression, as well as significantly higher heart rates and lower heart rate variability, than those in higher income groups. In full-term infants, maternal prenatal depression appears to promote higher birth weight, with elevated maternal heart rate as a likely mediating mechanism.

N-terminal pro-brain natriuretic peptide and associated factors in the general working population: a baseline survey of the Uranosaki cohort study

Few data on clinical characteristics associated with N-terminal pro-brain natriuretic peptide (NT-proBNP) or the clinical value of measuring NT-proBNP in the working population are available. The aim of the present study was to investigate the levels of NT-proBNP and their association with clinical variables in the Japanese general working population by using baseline data from the Uranosaki cohort study. In the study, the plasma concentration of NT-proBNP and some biomarkers were measured in addition to the standard health checkups at the workplace. Questionnaires regarding health-related quality of life (HR-QOL) were also completed. A total of 2140 participants were enrolled in the study. Plasma levels of NT-proBNP were positively associated with age, female sex, systolic blood pressure, pulse pressure, prevalent hypertension, smoking habit, high-density lipoprotein cholesterol (HDL-C), and prevalent proteinuria, and negatively associated with body mass index, lipid profiles except HDL-C, uric acid, renal function, and hemoglobin. Both the plasma concentration of high-molecular weight adiponectin and that of high-sensitivity troponin T were positively and independently associated with NT-proBNP. In addition, the HR-QOL score regarding sleep disorder was independently associated with NT-proBNP. Thus, we have obtained evidence that the plasma NT-proBNP is affected by several clinical variables in the general working population.

Current Psychosomatic Practice

Psychosomatic research has advanced over the past decades in dealing with complex biopsychosocial phenomena and may provide new effective modalities of patient care. Among psychosocial variables affecting individual vulnerability, course, and outcome of any medical disease, the role of chronic stress (allostatic load/overload) has emerged as a crucial factor. Assessment strategies include the Diagnostic Criteria for Psychosomatic Research. They are presented here in an updated version based on insights derived from studies carried out so far and encompass allostatic overload, type A behavior, alexithymia, the spectrum of maladaptive illness behavior, demoralization, irritable mood, and somatic symptoms secondary to a psychiatric disorder.
