The predictive power of depression screening procedures for veterans with coronary artery disease

A Potential Role for MAGI-1 in the Bi-Directional Relationship Between Major Depressive Disorder and Cardiovascular Disease

PURPOSE OF REVIEW

Major Depressive Disorder (MDD) is characterized by persistent symptoms such as fatigue, loss of interest in activities, feelings of sadness and worthlessness. MDD often coexist with cardiovascular disease (CVD), yet the precise link between these conditions remains unclear. This review explores factors underlying the development of MDD and CVD, including genetic, epigenetic, platelet activation, inflammation, hypothalamic-pituitary-adrenal (HPA) axis activation, endothelial cell (EC) dysfunction, and blood-brain barrier (BBB) disruption.

RECENT FINDINGS

Single nucleotide polymorphisms (SNPs) in the membrane-associated guanylate kinase WW and PDZ domain-containing protein 1 (MAGI-1) are associated with neuroticism and psychiatric disorders including MDD. SNPs in MAGI-1 are also linked to chronic inflammatory disorders such as spontaneous glomerulosclerosis, celiac disease, ulcerative colitis, and Crohn's disease. Increased MAGI-1 expression has been observed in colonic epithelial samples from Crohn's disease and ulcerative colitis patients. MAGI-1 also plays a role in regulating EC activation and atherogenesis in mice and is essential for Influenza A virus (IAV) infection, endoplasmic reticulum stress-induced EC apoptosis, and thrombin-induced EC permeability. Despite being understudied in human disease; evidence suggests that MAGI-1 may play a role in linking CVD and MDD. Therefore, further investigation of MAG-1 could be warranted to elucidate its potential involvement in these conditions.

Genetic correlation and causality assessment between post-traumatic stress disorder and coronary artery disease-related traits

Consistent evidence from observational studies supports a risk-increasing association between post-traumatic stress disorder (PTSD) and coronary artery disease (CAD); however, the mechanisms underlying their relationship remain poorly understood. This study assesses the genetic correlation and potential causal relationship between PTSD and CAD-related traits. We analysed genome-wide associated study summary data of PTSD (cases = 23,212, controls = 151,447) with CAD-related traits (sample size up to 408,458 individuals) to achieve our study objectives. Findings revealed a significant and positive genetic correlation between PTSD and CAD (r_G = 0.19, p = 3.47 × 10-2), and between PTSD and CAD traits of ischemic heart disease (genetic correlation [r_G] = 0.42, p = 5.17 × 10^-10), coronary arteriosclerosis (r_G = 0.32, p = 3.78 × 10^-7), and angina pectoris (r_G = 0.48, p = 1.14 × 10^-9). However, Mendelian randomisation (MR) analysis found no evidence for a significant causal association between PTSD and CAD traits, regardless of analysis direction (PTSD or CAD traits as the exposure or outcome variable). Findings from MR sensitivity analyses were consistent, suggesting that genetic liability to PTSD has no causal influence on any CAD trait and vice versa. In summary, our study provides evidence implicating a positive genetic correlation between PTSD with CAD-related traits, supporting evidence of a risk-increasing but non-causal association between them.

A systematic review and meta-analysis of serum and plasma cortisol levels in depressed patients versus control

Depression is associated with hyperactivity of the hypothalamo pituitary adrenal axis. Cortisol is a steroid hormone, released from the adrenal gland and is considered to be a biological marker of stress and anxiety. Serum or plasma cortisol levels have been previously studied in depressive patients but reported contradictory results. The present meta analysis aims to assess the serum or plasma concentration of cortisol in depressive patients compared with controls. We have conducted a systematic review with sequential meta analysis according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Web of Science, PubMed, Scopus, and PsycINFO databases, and published reference lists were searched up to January 2021. We have conducted a systematic review on PubMed for the following search (MeSH) terms ("Hydrocortisone"[Mesh]) AND "Depressive Disorder"[Mesh]). The RevMan 5.3 and Open Meta Analyst software was used with the standard mean difference (SMD) and 95% confidence intervals (CIs). The Jamovi and Open Meta Analyst Software were used to evaluate the publication bias, sensitivity analysis, and meta regression as possible sources of heterogeneity. Seventeen studies having a combined population (n) of 1400 (743 depressive patients and 657 controls) had satisfied the inclusion criteria for serum or plasma cortisol. The pooled SMD of the serum or plasma cortisol levels in depressive patients compared with controls was 1.18, (95% CI: 0.84, 1.52; P < 0.00001) with I2 = 85% (Ph < 0.00001). This meta analysis indicates a statistically significant mean difference in serum or plasma cortisol between depressed patients and controls. Meta analysis concluded that serum or plasma cortisol can differentiate depressed patients from nondepressed controls.

Severity, Progress, and Related Factors of Mood Disorders in Patients with Coronary Artery Disease: A Retrospective Study

Patients with coronary artery disease (CAD) are more likely to experience depression and anxiety, which, in turn, are risk factors for CAD. The Beck depression inventory (BDI) and Beck anxiety inventory (BAI) were applied for mood evaluation during hospitalization and again 3 months after discharge in 118 patients with CAD, and cardiopulmonary exercise tests were conducted in the outpatient department. Of the patients diagnosed with CAD, 40 (33.9%) had depressive moods, and 51 (43.2%) had anxious moods. A family history of CAD, low Korean activity scale index (KASI), and use of beta-blockers were independent factors causing depressive mood, while lower left ventricular ejection fraction (LVEF) and low KASI score were independent factors causing anxious mood. A considerable number of patients (35.7% with depressive mood and 25.0% with anxious mood) still had emotional problems after 3 months of discharge. The change values of BDI were associated with lower LVEF and longer hospital stay, while those of BAI was associated with a longer hospital stay. Since some patients had depressive and anxious moods after three months of discharge, evaluating and treating them are essential.

Factors Associated with Depression among Heart Failure Patients at Cardiac Follow-Up Clinics in Northwest Ethiopia, 2017: A Cross-Sectional Study

Background

Depression is a comorbid disorder in patients with heart failure and it is a major public health problem worldwide. Little is known about the depression among heart failure patients in low-income countries, while, in Ethiopia, none was studied.

Objective

This study is to assess the prevalence of depression and associated factors among heart failure patients at cardiac follow-up clinics at Amhara Region Referral Hospitals, Northwest Ethiopia, 2017.

Methods

A hospital based cross-sectional study was conducted between March 30, 2017, and May 15, 2017, G.C., by using a systematic random sampling technique to select 422 of 1395 HF patients. Structured interviewer-administered questionnaires and patient card review with a checklist that incorporates the PHQ-9 tool for depression measurement were used. The collected data were checked, coded, and entered into Epi-info version 7 and exported to SPSS version 20. Bivariate logistic regression at p-value <0.2 was exported to multivariate logistic regressions and p-value <0.05 was considered statistically significant.

Results

A total of 403 were included with a response rate of 95.5%. Among the participants, 51.1% had depressive symptoms. Factors associated with depressive symptoms were poor self-care behavior 1.60 [AOR (95% CI=1.01, 2.55)], poor social support 1.90 [AOR (95% CI=1.16, 3.12)], being female 2.70 [AOR (95% CI=1.44, 5.07)], current smoking history 4.96 [AOR (95% CI=1.54, 15.98)], and duration of heart failure (>1 year) 1.64 [AOR (95% CI=1.04, 2.59)].

Conclusions

Around half of the patients were depressive. The patients who had poor self-care behavior, were females, had poor social support, had a current history of smoking, and had duration of chronic heart failure >1 year need special attention. Therefore, all referral hospitals need efforts to focus on those problems and target improvements of depressive symptoms.

Depression and anxiety symptoms in cardiac patients: a cross-sectional hospital-based study in a Palestinian population

BACKGROUND

Mental health problems have an adverse effect on the course of cardiac disease. The integration of their diagnosis and treatment into cardiology care is generally poor. It is particularly challenging in cultural environments where mental health problems are stigmatized. The objective of the current study was to investigate the proportion of cardiac patients with depression and anxiety as well as factors associated with the presence of these symptoms in a Palestinian population.

METHODS

This cross-sectional hospital-based study was conducted on patients consecutively admitted with a new or existing cardiac diagnosis to one of the four main hospitals in Nablus, Palestine over an eight-month period. Data was obtained from hospital medical charts and an in-person interview, using a structured questionnaire with a sequence of validated instruments. All subjects were screened for depression and anxiety using the Cardiac Depression Scale (CDS) and the Depression Anxiety Stress Scale (DASS-42). Multivariate ordered logistic regression analyses were performed to identify factors among four categories (socio-demographic, clinical, psychosocial, lifestyle) independently associated with depression and anxiety.

RESULTS

In total, 1053 patients with a confirmed cardiac diagnosis were included in the study with a participation rate of 96%. Based on the CDS and DASS-42, 54% met the criteria for severe depression (CDS > 100) and 19.2% for severe-to-very severe anxiety (DASS-anxiety > 15), respectively. Symptoms of depression and anxiety were more prevalent among females and less educated patients. Factors independently associated with both depressive and anxiety symptoms were post-traumatic stress disorder symptoms, low level of self-esteem, high somatic symptoms, low physical and mental health component scores, active smoking, physical inactivity, and longer disease duration. Patients with depressive and anxiety symptoms also reported poor social support and lower resilience.

CONCLUSION

There was a high level of depression and anxiety in this sample of cardiac patients. The results point to characteristics of patients in particular need for mental health screening and suggest possible targets for intervention such as strengthening of social support and of physical activity. The integration of mental health services into cardiac rehabilitation in Palestine and comparable cultural settings is warranted from the time of first diagnosis and onward.

Schneider B, I. Twersky J. Implementing and feasibility testing depression screening using the electronic medical record for patients with type 2 diabetes admitted to the hospital

AIM

Is it feasible to implement a programme to screen for depression in patients admitted to the hospital for diabetes complications and use the electronic medical record to notify providers of their patient's depression score and give suggestions for medication and counselling?

DESIGN

A feasibility study was conducted with patients hospitalized with diabetes and depression in the Durham Veterans Affairs Medical Center, Durham, North Carolina, United States.

METHODS

Patients with type 2 diabetes were screened for depression. The healthcare provider was notified via the electronic medical record about the patients' depression scores. The provider discussed options for management of depression with the patient and initiated treatment.

RESULTS

The process of screening for depression at admission, notifying the provider by way of electronic medical record that the patient screened positive for depression with suggestions for medication and counseling was feasible and acceptable to providers and patients.

Low serum tryptophan predicts higher mortality in cardiovascular disease

BACKGROUND

The essential amino acid tryptophan is required for protein synthesis and formation of the neurotransmitter serotonin and may exert immunoregulatory functions. An accelerated tryptophan breakdown rate is associated with inflammation and immune activation.

MATERIALS AND METHODS

Serum concentrations of free tryptophan, neopterin and high-sensitivity C-reactive protein (hsCRP) were measured in 1196 patients with coronary artery disease (CAD) derived from the LUdwigshafen RIsk and Cardiovascular Health (LURIC) study.

RESULTS

Tryptophan concentrations did not differ between patients with (mean ± SD: 40.1 ± 9.8 μM) or without (42.3 ± 23.9 μM; not significant, Welch's test) angiographic CAD, but patients with CAD had higher neopterin (9.1 ± 8.2 nM) and hsCRP (9.3 ± 18.5 mg/L) concentrations compared to patients without (neopterin: 7.6 ± 4.7 nM, hsCRP: 5.8 ± 7.6 mg/L; both P < 0.0001). There existed an inverse correlation between serum tryptophan and neopterin (Spearman's rank correlation: rs = -0.273) and hsCRP (rs = -0.163; both P < 0.0001) concentrations. Median observation time was 10.5 years, and 385 patients had died, including 244 patients due to cardiovascular and 132 due to noncardiovascular causes. After adjustments for cardiovascular risk factors and other possible confounders, the hazard ratio (with 95% CI) in the first tryptophan quartile of the study population was 1.51 (1.19-1.90; P = 0.0006) for total mortality, 1.41 (1.05-1.89; P = 0.0224) for cardiovascular and 1.79 (1.20-2.67; P = 0.0042) for noncardiovascular mortalities, respectively, thus indicating a significantly higher risk of death in patients with tryptophan concentrations < 34 μM.

CONCLUSIONS

Low serum tryptophan in patients with CAD is associated with immune activation and indicates reduced life expectancy.

Depression and cardiac disease: epidemiology, mechanisms, and diagnosis

In patients with cardiovascular disease (CVD), depression is common, persistent, and associated with worse health-related quality of life, recurrent cardiac events, and mortality. Both physiological and behavioral factors—including endothelial dysfunction, platelet abnormalities, inflammation, autonomic nervous system dysfunction, and reduced engagement in health-promoting activities—may link depression with adverse cardiac outcomes. Because of the potential impact of depression on quality of life and cardiac outcomes, the American Heart Association has recommended routine depression screening of all cardiac patients with the 2- and 9-item Patient Health Questionnaires. However, despite the availability of these easy-to-use screening tools and effective treatments, depression is underrecognized and undertreated in patients with CVD. In this paper, we review the literature on epidemiology, phenomenology, comorbid conditions, and risk factors for depression in cardiac disease. We outline the associations between depression and cardiac outcomes, as well as the mechanisms that may mediate these links. Finally, we discuss the evidence for and against routine depression screening in patients with CVD and make specific recommendations for when and how to assess for depression in this high-risk population.

Pharmacy considerations in tobacco cessation for patients suffering from posttraumatic stress disorder

Multiple studies have associated post traumatic stress disorder (PTSD) with variable and high rates of smoking documented in different populations. This article will cover the neurobiology behind tobacco use, and its implications in those with PTSD. Discussion on cessation programs (e.g., effectiveness, drug interactions), and controversy over the use of varenicline will also be discussed.
