To what extent is multi-morbidity associated with new onset depression in patients attending cardiac rehabilitation?

Resolvin T4 enhances macrophage cholesterol efflux to reduce vascular disease

While cardiovascular disease (CVD) is one of the major co-morbidities in patients with rheumatoid arthritis (RA), the mechanism(s) that contribute to CVD in patients with RA remain to be fully elucidated. Herein, we observe that plasma concentrations of 13-series resolvin (RvT)4 negatively correlate with vascular lipid load in mouse inflammatory arthritis. Administration of RvT4 to male arthritic mice fed an atherogenic diet significantly reduces atherosclerosis. Assessment of the mechanisms elicited by this mediator demonstrates that RvT4 activates cholesterol efflux in lipid laden macrophages via a Scavenger Receptor class B type 1 (SR-BI)-Neutral Cholesterol Ester Hydrolase-dependent pathway. This leads to the reprogramming of lipid laden macrophages yielding tissue protection. Pharmacological inhibition or knockdown of macrophage SR-BI reverses the vasculo-protective activities of RvT4 in vitro and in male mice in vivo. Together these findings elucidate a RvT4-SR-BI centered mechanism that orchestrates macrophage responses to limit atherosclerosis during inflammatory arthritis.

A Cross-sectional Study of Depression among Non-dialysis Stage 3-5 Chronic Kidney Disease Patients

Depression is common among patients undergoing dialysis. However, there is a dearth of data on depression and its predictors among patients at different stages of chronic kidney disease (CKD). This study assessed the prevalence of depression and the relationships between depression and sociodemographic and clinical factors among non-dialysis CKD patients. A convenience sample of 88 CKD patients was recruited using a cross-sectional study design. The Beck Depression Inventory-II (BDI-II) was used to assess the levels of depression among CKD patients, with a cutoff score of ≥11. Data on the sociodemographic factors and clinical factors were also collected. Inferential statistics were used to determine the characteristics of the sample and assess the prevalence and severity of depression. Multiple regression analysis was used to assess the associations between the characteristics of the sample and depression. The overall mean BDI-II score was 6.23 ± 6.13. With a cutoff score of ≥11, patients with major depressive episodes constituted 18.2% of the sample. Stages of the disease, comorbidities, and sex were independently associated with a high depression score. The model explained 39% of the variation in the depression score. Depression is common among non-dialysis CKD patients. Screening for depression with brief validated tools should be integrated into routine clinical practice at renal clinics because patients in the advanced stages of CKD and those with multiple comorbidities require close attention. Furthermore, large studies assessing the prevalence and predictors of depression among different stages of CKD are required.

A pragmatic effectiveness-implementation study comparing trial evidence with routinely collected outcome data for patients receiving the REACH-HF home-based cardiac rehabilitation programme

BACKGROUND

Cardiac rehabilitation for heart failure continues to be greatly underused worldwide despite being a Class I recommendation in international clinical guidelines and uptake is low in women and patients with mental health comorbidities.

METHODS

Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) programme was implemented in four UK National Health Service early adopter sites ('Beacon Sites') between June 2019 and June 2020. Implementation and patient-reported outcome data were collected across sites as part of the National Audit of Cardiac Rehabilitation. The change in key outcomes before and after the supervised period of REACH-HF intervention across the Beacon Sites was assessed and compared to those of the intervention arm of the REACH-HF multicentre trial.

RESULTS

Compared to the REACH-HF multicentre trial, patients treated at the Beacon Site were more likely to be female (33.8% vs 22.9%), older (75.6 vs 70.1), had a more severe classification of heart failure (26.5% vs 17.7%), had poorer baseline health-related quality of life (MLHFQ score 36.1 vs 31.4), were more depressed (HADS score 6.4 vs 4.1) and anxious (HADS score 7.2 vs 4.7), and had lower exercise capacity (ISWT distance 190 m vs 274.7 m). There appeared to be a substantial heterogeneity in the implementation process across the four Beacon Sites as evidenced by the variation in levels of patient recruitment, operationalisation of the REACH-HF intervention and patient outcomes. Overall lower improvements in patient-reported outcomes at the Beacon Sites compared to the trial may reflect differences in the population studied (having higher morbidity at baseline) as well as the marked challenges in intervention delivery during the COVID-19 pandemic.

CONCLUSION

The results of this study illustrate the challenges in consistently implementing an intervention (shown to be clinically effective and cost-effective in a multicentre trial) into real-world practice, especially in the midst of a global pandemic. Further research is needed to establish the real-world effectiveness of the REACH-HF intervention in different populations.

The impact of physical conditions on the incidence of major depressive disorder in Chinese university students: Results from a longitudinal study

BACKGROUND

Major depressive disorder (MDD) is prevalent, and highly comorbid with physical illnesses. Few longitudinal studies have investigated the relationship between physical health conditions and MDD. The objectives of this study were to investigate the comorbid relationship between physical conditions and MDD, and the association between physical conditions and the 2-year risk of MDD.

METHODS

A study was conducted in first-year Chinese university students (n = 8,079) over two and half years, using a longitudinal design. An adapted version of the Composite International Diagnostic Interview (CIDI - 3.0) was used to assess for MDD. The presence of physician diagnosed physical conditions was assessed using ten self-report questions. Cross-sectional and longitudinal associations between self-reported physical conditions and MDD were estimated, adjusting for possible confounders.

RESULTS

The most frequently reported physical conditions were migraines, chronic rhinitis, and gastritis. We found that migraines, gastritis, and stomach ulcers were associated with a significantly higher lifetime prevalence of MDD than those without any physical health conditions. In those without a lifetime MDD, migraines, gastritis and stomach ulcers were also found to be significant predictors for 2-year risk of new onset MDD.

LIMITATIONS

Recall and selection biases are possible when using self-reporting measures. Additionally, the COVID-19 outbreak impacted the response rate at the second follow-up assessment. Lastly, the severity of the physical conditions was not measured.

CONCLUSIONS

Physical conditions and MDD are highly prevalent and comorbid in university students. Migraines, gastritis and stomach ulcers are associated with the risk of developing MDD. Future studies should further investigate how this information can be used to prevent MDD.

Systematic screening for anxiety and depression in cardiac rehabilitation - are we there yet?

BACKGROUND

Anxiety and depression are prevalent in 20% of patients with acute coronary syndrome (ACS) and associated with poor outcomes. Guidelines recommend screening for these conditions in cardiac rehabilitation (CR) however, clinical practice is inconsistent. Sparse knowledge exists on determinants for screening.

METHODS

This observational study used data from the National Audit of Cardiac Rehabilitation from January 2016-December 2019. A multivariate logistic regression model was performed to analyze patient- and provider level determinants for screening for anxiety and depression among patients with ACS.

RESULTS

The population consisted of 138,018 patients, where 82,507 (59.8%) were screened and 55,511 (40.2%) were not. Younger age, non-white ethnicity, living in areas of social deprivation, current smoking, body mass index>30, and physical activity<150 min per week were negatively correlated with patients being screened. Compared to patients having a percutaneous coronary intervention, patients undergoing coronary artery bypass grafting or medical treatment were less likely to be screened. History of anxiety, depression, osteoporosis, chronic back problems, and asthma were positively correlated with screening, while chronic obstructive pulmonary disease, diabetes, hypertension, and stroke were negatively correlated with screening. Regarding provider level, certification of CR centers was positively associated with screening, while looking over time data showed an incremental negative trend in screening from 2016 to 2019.

CONCLUSION

We found both patient and provider level determinants of screening for anxiety and depression. Clinical practice is still inconsistent especially for high-risk groups. We recommend systematic screening to enable tailored interventions which in turn may mitigate inequity in health outcomes.

Is improvement in depression in patients attending cardiac rehabilitation with new-onset depressive symptoms determined by patient characteristics?

Background

Patients with cardiovascular disease (CVD) commonly experience depressive symptoms which is associated with adverse outcome and increased mortality. Examining the baseline characteristics of cardiac rehabilitation (CR) patients that determine Hospital Anxiety and Depression Scale (HADS) depression outcome may facilitate adjustments in CR programme delivery. This study aims to investigate whether comorbidities, demographic and clinical characteristics of patients, with new-onset post-cardiac event depressive symptoms, determine change in their depression following CR.

Methods

Analysing the routine practice data of British Heart Foundation National Audit of Cardiac Rehabilitation between April 2012 and March 2018, an observational study was conducted. Patients with new-onset post-cardiac event depressive symptoms and no previous documented history of depression constituted the study population.

Results

The analyses included 64 658 CR patients (66.24±10.69 years, 75% male) with new-onset HADS measures, excluding patients with a history of depression. The comorbidities determining reduced likelihood of improvement in depression outcomes after CR were angina, diabetes, stroke, emphysema and chronic back problems. In addition, higher total number of comorbidities, increased weight, a higher HADS anxiety score, smoking at baseline, physical inactivity, presence of heart failure and being single were other significant determinants. However, receiving coronary artery bypass graft treatment was associated with better improvement.

Conclusion

The study identified specific baseline comorbid conditions of patients with new-onset depressive symptoms including angina, diabetes, stroke, emphysema and chronic back problems that were determinants of poorer mental health outcomes (HADS) following CR. Higher total number of comorbidities, increased weight, physical inactivity, smoking, presence of heart failure and being single were other determinants of a negative change in depression. These findings could help CR programmes focus on tailoring the CR intervention around comorbidity, physical activity status, weight management and smoking cessation in patients with new-onset depressive symptoms.

Factors That Predispose Women to Greater Depressive Symptoms: A Sex-, Age-, and Diagnosis-Matched Cardiac Rehabilitation Cohort

BACKGROUND

Depressive symptoms (DS) disproportionately affect women with cardiac disease; however, no analyses have been conducted that would allow for focused sex-specific interventions.

METHODS

Consecutively enrolled women (n = 663) were matched with men postcardiac revascularization at cardiac rehabilitation (CR) entry by primary diagnosis, age, and year of CR entry from database records (2006 to 2017). Multivariate analyses were conducted to determine predictors of DS (≥16 on the Center for Epidemiologic Studies Depression Scale) in all patients and men and women separately.

RESULTS

In bivariate analysis, women were more likely than men to have DS (30.2% vs 19.3%; P < 0.001) in the matched cohort. A greater proportion of women than men had DS in all 10-year age categories (P < 0.05) except youngest (<50 years; 37% vs 30.4%; P = 0.7) and oldest (≥80; 12.3% vs 10.3%; P = 0.8). DS peaked in women aged 50 to 59 (42.5%) and men <50 years (30.4%). In all patients, independent predictors of DS were younger age, lower cardiorespiratory fitness (VO_2peak), being unemployed, greater comorbidities, smoking, anxiolytics, antidepressants, not being married, but not sex. Shared predictors in women-only and men-only analyses were younger age, lower VO_2peak, antidepressants, and being unemployed. Unique predictors for women were obesity, smoking, and delayed CR entry and, for men, hypertension, myocardial infarction, anxiolytics, and not being married.

CONCLUSIONS

Despite matching for age and diagnosis, women were more likely to have DS than men. However, sex was not a predictor of DS in multivariate analyses. This suggests that the profile of women predisposes them to greater DS. Obesity, smoking, and greater delayed CR entry were unique correlates for women and targets for intervention.

Establishing the Feasibility of Group Metacognitive Therapy for Anxiety and Depression in Cardiac Rehabilitation: A Single-Blind Randomized Pilot Study

BACKGROUND

Anxiety and depression are common in cardiac rehabilitation (CR) patients. However, CR programs which incorporate psychological techniques achieve modest reductions in emotional distress. More efficacious interventions that can be easily integrated within services are required. A promising alternative to current psychological interventions is metacognitive therapy (MCT). The aim was to evaluate the acceptability and feasibility of delivering Group-MCT to CR patients experiencing symptoms of anxiety and depression.

METHOD AND RESULTS

Fifty-two CR patients with elevated anxiety and/or depression were recruited to a single-blind randomized feasibility trial across three UK National Health Service Trusts and randomized to usual CR or usual CR plus six weekly sessions of group-MCT. Acceptability and feasibility of adding group-MCT to CR was based on recruitment rates, withdrawal, and drop-out by the primary end-point of 4 months; number of MCT and CR sessions attended; completion of follow-up questionnaires; and ability of the outcome measures to discriminate between patients. The study was also used to re-estimate the required sample size for a full-scale trial. We also examined the extent by which non-specialists adhered to the Group-MCT protocol. Group-MCT was found to be feasible and acceptable for CR patients with anxiety and depression. Recruitment and retention of participants was high, and attendance rates at CR were similar for both groups.

CONCLUSION

The results suggest the addition of MCT to CR did not have a negative impact on retention and support a full-scale trial of Group-MCT for cardiac patients.
