Do family-oriented interventions reduce poststroke depression? A systematic review and recommendations for practice

Depressive symptoms occurring after stroke by age, sex and socioeconomic status in six population-based studies: Longitudinal analyses and meta-analyses

AIMS

Population-based cohort studies that examined the effects of stroke on depressive symptoms in elderly participants with and without stroke in different countries/regions had yielded scant evidence. The objectives of this multi-cohort study were to identify the relationships between stroke and depressive symptoms and to assess the pooled risks of depressive symptoms in total populations and in stratified samples by age, sex, education levels, and total household income in large-scale studies.

METHODS

The associations in the overall participants in the six cohorts were examined using univariate and multivariable Cox proportional hazards models. The relationships in the population subgroups of the cohorts were determined using multivariable Cox regression models. Crude hazard ratios (HRs) were estimated, and adjusted or time-varying HRs were calculated and then pooled by meta-analyses.

RESULTS

During a median follow-up time of 3.8 (interquartile range [IQR]: 2.2-4.5) -7.9 (IQR: 4.0-8.0) years, 18267 participants out of 62150 participants developed incident cases of depressive symptoms. In the univariate Cox regression analyses, stroke was consistently linked to depressive symptoms across all studies, with HRs ranging from 1.39 (95% confidence interval [CI]: 1.04-1.85) to 1.84 (95% CI: 1.38-2.46). Adjusted HRs varied between 1.19 (95% CI: 0.89-1.59) and 1.48 (95% CI: 1.00-1.98), and time-varying HRs remained largely unchanged. According to the meta-analysis of overall HRs, stroke survivors were more likely than non-survivors to develop depressive symptoms (pooled HR: 1.35 (95% CI: 1.26-1.44)).

CONCLUSIONS

In general, stroke significantly increased the risk of depressive symptoms in total and stratified participants in most cohorts. In the future, extensive research will be needed to assess the variations in associations between various population subgroups.

Eye movement desensitization and reprocessing for post-stroke post-traumatic stress disorder: Case report using the three-phase approach

Medically-induced post-traumatic stress disorder (PTSD) is substantially more prevalent than PTSD in the general population. In people with stroke, it can impact as many as 23% of patients, with negative effects on mental health as well as stroke-related disability. Medically-induced PTSD may have unique features compared to other forms of PTSD, and therefore there is a pressing need to evaluate existing treatments for PTSD in this context. The current study reports on the feasibility, safety, and efficacy of Eye Movement Desensitization and Reprocessing (EMDR) for PTSD subsequent to a pontine stroke. Using a quasi-experimental case design, a 44-year-old Caucasian woman received EMDR delivered via telehealth. Self-report measures were obtained at baseline, pre-EMDR, and post-EMDR, with brief neuropsychological testing pre/post-EMDR. After 3 sessions of EMDR, the patient no longer met criteria for PTSD, and showed clinically significant reductions in depressive and generalized anxiety symptoms. With proper safety provisions, it is feasible to deliver EMDR via telehealth to alleviate post-stroke PTSD. Reduced linguistic demands of EMDR may be particularly appealing for persons with neurological disorders as compared to other trauma therapies. Further work is also needed to understand the parameters of baseline neuropsychological function that could impact response to intervention.

Post-Stroke Experiences and Rehabilitation Needs of Community-Dwelling Chinese Stroke Survivors: A Qualitative Study

Stroke survivors encounter significant limitations in daily life activities and face increased risk of health complications such as stroke recurrence. Considering the escalating demand for personalised community rehabilitation services, this qualitative study was conducted to understand the current recovery experiences, needs, and expectations of community-dwelling stroke survivors. Fifty stroke survivors were recruited from two tertiary teaching hospitals and community centres in two provinces in mainland China. Semi-structured interviews were carried out, and participants were asked to describe their experiences of stroke, current lifestyles, exercise habits, and rehabilitation needs and expectations. Resulting data were thematically analysed. The majority of participants were first-time stroke survivors (80%) and lived with their family or caregivers (92%). Four main themes and twelve sub-themes emerged from the data: (1) shifts in social life, (2) shaken sense of self and perceived helplessness, (3) complex rehabilitation needs, and (4) perceptions and patterns of physical activity. Findings suggest that though survivors recognised their need for further rehabilitation, their demands remained unmet due to a combination of personal and external factors such as limited mobility and the absence of supportive companions and accessible facilities. The enhancement and diversification of home rehabilitation strategies are therefore necessary to make community rehabilitation more accessible and equitable.

Prevention and Management of Diabetes-Related Foot Ulcers through Informal Caregiver Involvement: A Systematic Review

BACKGROUND

The literature remains unclear whether involving informal caregivers in diabetes self-care could lead to improved diabetic foot outcomes for persons at risk and/or with foot ulcer. In this review, we synthesized evidence of the impact of interventions involving informal caregivers in the prevention and/or management of diabetes-related foot ulcers.

METHODS

A systematic review based on PRISMA, and Synthesis Without Meta-analysis (SWiM) guidelines was conducted. MEDLINE (Ovid), Embase (Ovid), PsycINFO, CINAHL, and Cochrane Central Register of Controlled Trial of the Cochrane Library databases were searched from inception to February 2021. The following MESH terms were used: diabetic foot, foot ulcer, foot disease, diabetes mellitus, caregiver, family caregiver ,and family. Experimental studies involving persons with diabetes, with or at risk of foot ulcers and their caregivers were included. Data were extracted from included studies and narrative synthesis of findings undertaken.

RESULTS

Following the search of databases, 9275 articles were screened and 10 met the inclusion criteria. Studies were RCTs (n = 5), non-RCTs (n = 1), and prepoststudies (n = 4). Informal caregivers through the intervention programmes were engaged in diverse roles that resulted in improved foot ulcer prevention and/or management outcomes such as improved foot care behaviors, increased diabetes knowledge, decreased HbA1c (mmol/mol or %), improved wound healing, and decreased limb amputations rates. Engaging both caregivers and the person with diabetes in education and hands-on skills training on wound care and foot checks were distinctive characteristics of interventions that consistently produced improved foot self-care behavior and clinically significant improvement in wound healing.

CONCLUSION

Informal caregivers play diverse and significant roles that seem to strengthen interventions and resulted in improved diabetes-related foot ulcer prevention and/or management outcomes. However, there are multiple intervention types and delivery strategies, and these may need to be considered by researchers and practitioners when planning programs for diabetes-related foot ulcers.

Effectiveness of technology-based interventions on psychological morbidities, quality of life for informal caregivers of stroke survivors: A systematic review and meta-analysis

AIMS

To evaluate the effectiveness of technology-based interventions in reducing psychological morbidities such as depressive symptomology, anxiety, burden and improving quality of life and self-efficacy in informal caregivers of stroke survivors.

DESIGN

A systematic review and meta-analysis.

DATA SOURCES

An extensive search was systematically undertaken at CENTRAL, PubMed, Embase, Scopus, CINHAL, Web of Science and PsycInfo until January 2021. Grey literature and dissertations were searched in Google Scholar, ProQuest & Scholarbank@NUS. Studies involving registered trials were retrieved from Clinicaltrials.gov and CENTRAL, respectively.

REVIEW METHODS

Two reviewers independently screened the trials, conducted quality appraisal and extracted the data. Quality of the studies included in the review was assessed using Cochrane Risk of bias tool. Meta-analysis was conducted using RevMan 5.4. Narrative synthesis was performed for studies where results could not be pooled statistically. The results were reported abiding Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

This review included 15 trials with a total of 1276 informal caregivers of stroke survivors. Eleven trials were included in the meta-analysis. Subgroup analyses revealed that technology-based interventions with structured educational programs were statistically significant in reducing depressive symptoms (d = -0.27, 95% CI [-0.49 to -0.05], p = .02). Technology-based interventions with structured educational programs <3-month revealed significant effects (d = -0.31, 95% CI [-0.49 to -0.13], p = .0009). Results of narrative synthesis reported technology-based intervention with face-to-face training minimized depressive symptoms of informal caregivers. Notably, there were no statistically significant effects on anxiety, burden, quality of life and self-efficacy outcomes.

CONCLUSION

Technology-based interventions had beneficial effects in alleviating depressive symptoms among informal caregivers.

IMPACT

Technology-based interventions serve as a support mechanism for informal caregivers of stroke survivors who face time-constrains. Further high-quality randomized controlled trials are warranted to elucidate sustainability, optimal format and dosage of intervention.

Evidence available for patient-identified priorities in depression research: results of 11 rapid responses

OBJECTIVES

Patient priority setting projects (PPSPs) can reduce research agenda bias. A key element of PPSPs is a review of available literature to determine if the proposed research priorities have been addressed, identify research gaps, recognise opportunities for knowledge translation (KT) and avoid duplication of research efforts. We conducted rapid responses for 11 patient-identified priorities in depression to provide a map of the existing evidence.

DESIGN

Eleven rapid responses.

DATA SOURCES

Single electronic database (PubMed).

ELIGIBILITY CRITERIA

Each rapid response had unique eligibility criteria. For study designs, we used a stepwise inclusion process that started with systematic reviews (SRs) if available, then randomised controlled trials and observational studies as necessary.

RESULTS

For all but one of the rapid responses we identified existing SRs (median 7 SRs per rapid response, range 0-179). There were questions where extensive evidence exists (ie, hundreds of primary studies), yet uncertainties remain. For example, there is evidence supporting the effectiveness of many non-pharmacological interventions (including psychological interventions and exercise) to reduce depressive symptoms. However, targeted research is needed that addresses comparative effectiveness of promising interventions, specific populations of interest (eg, children, minority groups) and adverse effects.

CONCLUSIONS

We identified an extensive body of evidence addressing patient priorities in depression and mapped the results and limitations of existing evidence, areas of uncertainty and general directions for future research. This work can serve as a solid foundation to guide future research in depression and KT activities. Integrated knowledge syntheses bring value to the PPSP process; however, the role of knowledge synthesis in PPSPs and methodological approaches are not well defined at present.

Investigation of the emotional network in depression after stroke: A study of multivariate Granger causality analysis of fMRI data

OBJECTIVE

Depression after stroke (DAS) is a serious complication of stroke that significantly restricts rehabilitation. Brain imaging technology is an important method for studying the emotional network of DAS. However, few studies have focused on dynamic interactions within the network. The aim of this study was to investigate the emotional network of frontal lobe DAS using the multivariate Granger causality analysis (GCA) method, a technique that can estimate the association among the brain areas to analyze functional magnetic resonance imaging (fMRI) data collected from DAS and no depression after stroke (NDAS).

METHOD

Thirty-six first-time ischemic right frontal lobe stroke patients underwent resting-state fMRI (rs-fMRI) scans. The clinical assessment scale used for screening subjects was as follows: the 24-item Hamilton Rating Scale for Depression (HAMD-24), the National Institutes of Health Stroke Scale (NIHSS), the Mini-Mental State Examination (MMSE), and the Barthel Index (BI). The multivariate GCA method was used to analyze fMRI data collected from DAS and NDAS.

RESULTS

The results showed positive regulations in the order from the ventromedial prefrontal cortex (VMPFC), the anterior cingulate cortex (ACC), and the amygdala (AMYG) to the thalamus, and when the interaction order is opposite, the moderating effect is negative. The thalamus could predict the negative activity of the insular (IC) via the ACC. The dorsolateral prefrontal cortex (DLPFC) could predict the activity of the ACC via the temporal pole (TP).

CONCLUSION

This study found a VMPFC-ACC-AMYG-thalamus emotional circuit to explain the network between different brain regions associated with DAS. The DLPFC and TP play an important role in the emotional regulation of DAS, and the function of the IC is regulated negatively by the thalamus. These findings advance the neural theory of DAS, which is based on the functional relationship between different brain areas.

Use of mobile applications in post-stroke rehabilitation: a systematic review

OBJECTIVE

Information technology and mobile devices are potentially beneficial and useful in the management of patients who have had stroke, including recognition, translation, assessment, and rehabilitation. The objective of this study was to determine the effectiveness of mobile applications in the rehabilitation of stroke survivors.

METHODS

A literature search appraising the effectiveness of mobile applications in the rehabilitation of stroke survivors was performed on PubMed, Embase, Science Citation Index Expanded-SCIE, and EBSCO-CINAHL from their inception until May 28th, 2017. Two reviewers independently screened the literature according to eligibility criteria, evaluated study quality, and collected data from the articles included.

RESULTS

Of the 3574 articles screened, 12 studies met the eligibility criteria of the systematic review. Of these, 2 studies were randomized controlled trials and the remaining 10 were before-after studies, of which only 2 had control groups. The mobile applications encompassed 5 rehabilitation areas, 5 in physical function, 4 in language function, 2 in cognitive function, and 1 risk factor reduction. Of these 12 studies, 9 reported significant improvements in function, while in 3 studies the descriptive statistics indicated favorable changes after intervention.

CONCLUSIONS

Although the use of mobile applications in the rehabilitation of stroke survivors was effective, it is clear from this systematic review that more research is needed to verify their effectiveness.

A Study of the Brain Functional Network of Post-Stroke Depression in Three Different Lesion Locations

Research on the mechanism of post stroke depression (PSD) is the key way to improve the treatment of PSD. However, the functional brain network of PSD has not been entirely supported by the results of functional magnetic resonance imaging (fMRI) studies. The aims of this study are to investigate the brain response of PSD in three different lesions. The brain responses of the three PSD subgroups were similar. However, each subgroup had its own characteristics of the brain network. In the temporal lobe subgroup, the right thalamus had increased degree centrality (DC) values which were different from the other two subgroups. In the frontal lobe subgroup, the left dorsolateral prefrontal cortex, caudate, and postcentral gyrus had increased DC values which were different from the other two subgroups. The hemodynamic response of PSD indicates that PSD has activities of similar emotional networks, of which the negative network realizes its function through the limbic system and default mode network. The brain network has unique characteristics for different lesion locations. The neurological function of the lesion location, the compensatory mechanism of the brain, and the mechanism of integrity and locality of the brain are the important factors in the individual emotional network.

A Study of the Brain Abnormalities of Post-Stroke Depression in Frontal Lobe Lesion

Post stroke depression (PSD) is a serious complication of stroke. Brain imaging is an important method of studying the mechanism of PSD. However, few studies have focused on the single lesion location. The aim of this study was to investigate the brain mechanism of frontal lobe PSD using combined voxel-based morphometry (VBM) and functional magnetic resonance imaging (fMRI). In total, 30 first-time ischemic frontal lobe stroke patients underwent T1 weighted MRI and resting-state fMRI scans. Clinical assessments included the 24-item Hamilton Rating Scale for Depression, the National Institutes of Health Stroke Scale, and the Mini-Mental State Examination. In our result, decreased gray matter (GM) volume in patients was observed in the prefrontal cortex, limbic system and motor cortex. The anterior cingulate cortex, selected as a seed to perform connectivity analyses, showed a greatly decreased functional connectivity with the prefrontal cortex, cingulate cortex, and motor cortex, but had an increased functional connectivity with the hippocampus gyrus, parahippocampa gyrus, insular, and amygdala. Stroke lesion location reduces excitability of brain areas in the ipsilateral brain. PSD affects mood through the brain network of the prefrontal-limbic circuit. Some brain networks, including motor cortex and the default mode network, show other characteristics of PSD brain network.

Risk Factors for Post-stroke Depression: A Meta-analysis

Background: Stroke not only impacts patients physically but also economically. Post-stroke depression (PSD), as a common complication of stroke, always obstructs the process of stroke rehabilitation. Accordingly, defining the risk factors associated with PSD has extraordinary importance. Although there have been many studies investigating the risk factors for PSD, the results are inconsistent.

Objectives: The objectives of this study were to identify the risk factors for PSD by evidence-based medicine.

Data sources: A systematic and comprehensive database search was performed of PubMed, Medline, CENTRAL, EMBASE.com, the Cochrane library and Web of Science for Literature, covering publications from January 1, 1998 to November 19, 2016.

Study Selection: Studies on risk factors for PSD were identified, according to inclusion and exclusion criteria. The risk of bias tool, described in the Cochrane Handbook version 5.1.0, was used to assess the quality of each study. Meta-analysis was performed using RevMan 5.3 software.

Results: Thirty-six studies were included for review. A history of mental illness was the highest ranking modifiable risk factor; other risk factors for PSD were female gender, age (<70 years), neuroticism, family history, severity of stroke, and level of handicap. Social support was a protective factor for PSD.

Conclusion: There are many factors that have effects on PSD. The severity of stroke is an important factor in the occurrence of PSD. Mental history is a possible predictor of PSD. Prevention of PSD requires social and family participation.
