Illness beliefs about depression among patients seeking depression care and patients seeking cardiac care: an exploratory analysis using a mixed method design

Depression screening in patients with coronary heart disease : A narrative review of the current evidence

In view of the large and sometimes conflicting body of research, this narrative review summarizes the current evidence on depression screening in patients with coronary heart disease. Depression is a risk factor for development and progression of coronary heart disease. Consequently, many international cardiac guidelines recommend screening for depression in patients with coronary heart disease. However, the efficacy and implementation of these guidelines are debated due to the lack of empirical evidence supporting the benefits of routine depression screening. Studies conducted in cardiac routine care support this assumption: Patients with positive depression screens do not receive adequate follow-up care, which highlights gaps in the detection-to-treatment pathway. Barriers to effective screening and treatment include system-level factors, such as insufficient integration of mental health resources in cardiology, and patient-related factors like stigma and low acceptance of mental health treatment. Innovative interventions that address these barriers and involve patients as active partners in depression care should be developed through a theory-driven, transparent, multistage process involving key stakeholders such as patients, nurses, and cardiologists. A sound methodological evaluation of such multilevel interventions could answer the question of whether early detection of depression in patients with coronary heart disease would lead to health benefits.

Family Functioning, Illness-Related Self-Regulation Processes, and Clinical Outcomes in Major Depression: A Prospective Study in Greece

Major depressive disorder (MDD) is a common, seriously impairing, and often recurrent mental disorder. Based on the predictions of the Circumplex Model of Marital and Family Systems and the Common-Sense Self-Regulation Model, the aim of the present prospective study is to examine the predictive value of clinical outcomes of a process model in which associations between perceived family functioning and patient's clinical outcomes (i.e., symptom severity and suicide risk) are mediated by illness representations and coping strategies. A total of 113 patients with a clinical diagnosis of MDD (16.8% males and 83.2% females) aged 47.25 ± 13.98 years and recruited from the outpatient department and the mobile mental health unit of the Psychiatric Clinic of the University Hospital of Heraklion in Crete, Greece, and from a Greek online depression peer-support group participated in the study. Family functioning was assessed in terms of cohesion and flexibility (Family Adaptability and Cohesion Evaluation Scales IV) at baseline. Illness representations (Illness Perception Questionnaire-Mental Health) and coping strategies (Brief Cope Orientation to Problems Experienced) were measured about five months later (5.04 ± 1.16 months). Symptom severity (Beck Depression Inventory) and suicidality (Risk Assessment Suicidality Scale) were measured about 10 months after the baseline assessment (9.56 ± 2.52 months). The results indicated that representations about MDD impact and symptom severity serially mediated the association between family cohesion and suicide risk in MDD. Furthermore, family cohesion was found to be linked with maladaptive coping through MDD impact representations. Family-based psychotherapeutic interventions specifically designed to target unhealthy family functioning, along with negative illness perceptions and dysfunctional coping, could be further developed and explored as adjunctive therapy to standard treatment in MDD.

Understanding care needs of cancer patients with depressive symptoms: The importance of patients' recognition of depressive symptoms

Objective

The majority of cancer patients with depressive symptoms does not perceive a need for psychological care. Reasons for this are still unclear. We examined the mediating role of cancer patients' perceptions of depressive symptoms in the relationship between depressive symptoms and perceived need for psychological care.

Methods

For this cross‐sectional study, we recruited 127 Dutch cancer patients with moderate to severe levels of depressive symptoms (Patient Health Questionnaire [PHQ]‐9≥10) who did not receive professional psychological care. Depressive symptoms were measured with the PHQ‐9 questionnaire, by using three different depression score operationalizations. We used mediation analyses to test the mediating role of patients' illness perceptions (measured with subscales of the Brief Illness Perception Questionnaire) in the relation between depressive symptoms and need for care.

Results

Whilst results did not show significant direct associations between depressive symptoms and perceived need for psychological care, we found positive indirect effects of severity (B = 0.07, SE = 0.04, p < 0.02), meeting the DSM‐5 diagnosis (B = 0.45, SE = 0.26, p < 0.02) and having relatively more affective symptoms (B = 2.37, SE = 1.10, p < 0.02) on need for care through the identity perception.

Conclusions

Including assessments of patients' recognition of depressive symptoms and their perceptions of depression treatment efficacy might improve depression screening in cancer patients by more accurately identifying those with a need for psychological care. Moreover, improving patients' knowledge and recognition of symptoms as being depressive symptoms might be a possible target point in increasing care needs and hereby optimizing the uptake of psychological care in cancer patients with depressive symptoms.

A reduced state of being: The role of culture in illness perceptions of young adults diagnosed with depressive disorders in Singapore

Illness perceptions form a key part of common-sense models which are used widely to explain variations in patient behaviours in healthcare. Despite the pervasiveness of depressive disorders worldwide and in young adults, illness perceptions of depressive disorders have not yet been well understood. Moreover, while a high proportion of cases of depressive disorders reside in South-east Asia, few have explored illness perceptions that are culturally relevant to this region. To address these limitations, this study aimed to understand illness perceptions of young adults diagnosed with depressive disorders. Face-to-face semi-structured interviews were conducted among Chinese, Malay, and Indian young adults aged 20 to 35 years old, who were seeking treatment at a psychiatric hospital. Data reached saturation after 33 interviews (10 to 12 interviews per ethnic group) and five themes emerged from the thematic analysis: 1) A reduced state of being experienced at a point of goal disengagement, 2) the accumulation of chronic stressors in a system that demands success and discourages the pursuit of personally meaningful goals, 3) a wide range of symptoms that are uncontrollable and disabling, 4) poor decision making resulting in wasted opportunities, with some positive takeaways, and 5) accepting the chronicity of depression. Young adults typically experienced depression as a reduced state of being and it was thought of cognitively as an entity that may be a part of or separate from the self. Over and beyond these aspects of cognitive representations was the emergence of themes depicting conflicts and dilemmas between the self and the social environment that threatened self-identity and autonomy. Addressing these conflicts in therapy would therefore be of utmost relevance for young adults recovering from depressive disorders in the local setting.

Investigating patients´ views on screening for depression in cardiac practice: A qualitative interview study

OBJECTIVE

Recommendations on screening for depression in patients with coronary heart disease (CHD) are highly debated. While recent research has prioritized efficacy studies, little is known about what is potentially required for screening to be efficacious. Expanding our knowledge of how patients with CHD view screening is likely to pose a first step towards addressing this gap. We aimed to investigate patients ́ views on routine screening for depression in cardiac practice.

METHODS

This exploratory, qualitative study was conducted among 12 patients with CHD, who completed semi-structured interviews. We used a purposive sampling strategy to include patients within a range of ages, gender and self-reported depression. Thematic analysis was carried out.

RESULTS

We identified four main themes: Acceptance, utility, barriers and expectations. Patients in this sample appeared to be in favor of standardized routine screening for depression in cardiac practice, if the rationale was disclosed. Patients reported that standardized screening addresses holistic care demands, promotes validation of individual symptom burden and legitimizes the display of psychological distress in cardiac practice. Yet, skepticism towards the validity of screening instruments and perceived stigmatization could pose a main barrier to screening efficacy. Patients expected to receive feedback on results and consecutive recommendations.

CONCLUSION

We found that depression screening is endorsed by patients with CHD in this study sample. Standardized routine screening procedures could serve as a useful tool to combat stigmatization, and encourage patients to display symptoms of depression towards cardiologists. The efficacy of depression screening could potentially be enhanced by tailoring the screening process towards patients´ needs.

An Integrative Pharmacology-Based Strategy to Uncover the Mechanism of Xiong-Pi-Fang in Treating Coronary Heart Disease with Depression

Objectives: This study aimed to explore the mechanism of Xiong-Pi-Fang (XPF) in the treatment of coronary heart disease (CHD) with depression by an integrative strategy combining serum pharmacochemistry, network pharmacology analysis, and experimental validation. Methods: An ultrahigh performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS) method was constructed to identify compounds in rat serum after oral administration of XPF, and a component-target network was established using Cytoscape, between the targets of XPF ingredients and CHD with depression. Furthermore, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed to deduce the mechanism of XPF in treating CHD with depression. Finally, in a chronic unpredictable mild stress (CUMS)-and isoproterenol (ISO)-induced rat model, TUNEL was used to detect the apoptosis index of the myocardium and hippocampus, ELISA and western blot were used to detect the predicted hub targets, namely AngII, 5-HT, cAMP, PKA, CREB, BDNF, Bcl-2, Bax, Cyt-c, and caspase-3. Results: We identified 51 compounds in rat serum after oral administration of XPF, which mainly included phenolic acids, saponins, and flavonoids. Network pharmacology analysis revealed that XPF may regulate targets, such as ACE2, HTR1A, HTR2A, AKT1, PKIA, CREB1, BDNF, BCL2, BAX, CASP3, cAMP signaling pathway, and cell apoptosis process in the treatment of CHD with depression. ELISA analysis showed that XPF decreased Ang-II content in the circulation and central nervous system, inhibited 5-HT levels in peripheral circulation, and increased 5-HT content in the central nervous system and cAMP content in the myocardia and hippocampus. Meanwhile, western blot analysis indicated that XPF could upregulate the expression levels of PKA, CREB, and BDNF both in the myocardia and hippocampus. TUNEL staining indicated that the apoptosis index of myocardial and hippocampal cells increased in CUMS-and ISO-induced CHD in rats under depression, and XPF could increase the expression of Bcl-2, inhibit the expression of Bax, Cyt-c, and caspase-3, and rectify the injury of the hippocampus and myocardium, which exerted antidepressant and antimyocardial ischemia effects. Conclusion: Our study proposed an integrated strategy, combining serum pharmacochemistry and network pharmacology to investigate the mechanisms of XPF in treating CHD with depression. The mechanism of XPF in treating CHD with depression may be related to the activation of the cAMP signaling pathway and the inhibition of the apoptosis.

Lessons learned from an attempted randomized-controlled feasibility trial on "WIDeCAD" - An internet-based depression treatment for people living with coronary artery disease (CAD)

Despite the high prevalence of comorbid depression in people living with coronary artery disease (CAD), uptake of psychological treatment is generally low. This study was designed to investigate the feasibility of an internet-based cognitive-behavioral (iCBT) depression intervention for people with CAD and depressive symptoms.

METHODS

People with CAD and depressive symptoms (PHQ-9 ≥ 5) were randomly assigned to the eight modules comprising iCBT (N = 18), or waitlist-control (N = 16). Measures were taken at baseline (t1) and at post-treatment (eight weeks after randomization, t2). Feasibility-related outcomes were recruitment strategy, study attrition, intervention dropout, satisfaction, negative effects as well as the potential of the intervention to affect likely outcomes in a future full-scale trial (depression, anxiety, quality of life, fear of progression). Data analyses were based on intention-to-treat principles. Linear regression models were used to detect between group differences. Linear Mixed Models were used to model potential changes over time.

RESULTS

This trial was terminated prior to a-priori defined sample size has been reached given low recruitment success as well as high intervention dropout (88%) and study attrition (23%). On average, participants in the intervention group completed M = 2.78 (SD = 3.23) modules. Participants in the waitlist control group barely started one module (M = 0.82, SD = 1.81). The satisfaction with the intervention was low (M = 20.6, SD = 0.88). Participants reported no negative effects attributed to the iCBT. Differences between groups with regard to depression, anxiety, fear of progression and quality of life remained non-significant (p > 0.05).

CONCLUSION

This trial failed to recruit a sufficient number of participants. Future work should explore potential pitfalls with regards to the reach and persuasiveness of internet interventions for people living with CAD. The study gives important indications for future studies with regard to the need for new ideas to reach and treat people with CAD and depression.
