Acupuncture for post-stroke depression: a systematic review and network meta-analysis

The effect of motivational interviewing on patients with early post-stroke depression: a quasi-experimental study

BACKGROUND

Post-stroke depression (PSD) constitutes an important complication of stroke, affecting approximately one-third of stroke patients. PSD decreases rehabilitation motivation, delays function recovery, and increases the family and social burden of stroke patients. Motivational interviewing (MI) may be an effective and practical intervention strategy, but its effectiveness in improving PSD remains uncertain.

METHODS

A parallel two-group quasi-experimental study was conducted. Patients with early PSD were recruited from the neurology department of a hospital in southeast China and were allocated to the control group and intervention group by wards. Patients in the intervention group received one session of face-to-face motivational interviewing and three sessions of telephone motivational interviewing, while patients in the control group received routine nursing and follow-up of the neurology department. Outcomes including depression, sleep quality, and quality of life were evaluated at baseline (T0), after intervention immediately (T1) and three months after intervention (T2). Descriptive statistics, t-test, Mann-Whitney U test, Wilcoxon signed rank sum test and generalized estimating equation were used to analyze data.

RESULTS

There were no significant differences in patients' sociodemographic and clinical information between the intervention and control groups at baseline. The scores for depression were statistically different between the two groups (Z=-5.757, p < 0.001) at T1 and T2 (t=-7.964, p < 0.001). The scores for sleep quality were statistically different between the two groups at T1 (Z=-2.840, p = 0.005). The result of the generalized estimating equation modeling analyses indicated that interaction effects were statistically significant in depression and sleep quality scores. The intervention group showed a significantly higher rate of decrease in the depression score from T0 to T1 (95% CI: -11.227 to -7.748, p < 0.001) and T0 to T2 (95% CI: -11.683, -6.170, p < 0.001), compared with the control group; the intervention group had a greater reduction in the sleep score from T0 to T1 (95% CI: -2.502 to -0.962, p < 0.001), compared with the control group.

CONCLUSIONS

MI could effectively improve depression and sleep quality in patients with early PSD. However, MI failed to improve quality of life in patients with early PSD. These findings provide a foundation for future large-scale randomized controlled trials to further evaluate the efficacy of MI in patients with early PSD.

Post-stroke depression: exploring gut microbiota-mediated barrier dysfunction through immune regulation

Post-stroke depression (PSD) is one of the most common and devastating neuropsychiatric complications in stroke patients, affecting more than one-third of survivors of ischemic stroke (IS). Despite its high incidence, PSD is often overlooked or undertreated in clinical practice, and effective preventive measures and therapeutic interventions remain limited. Although the exact mechanisms of PSD are not fully understood, emerging evidence suggests that the gut microbiota plays a key role in regulating gut-brain communication. This has sparked great interest in the relationship between the microbiota-gut-brain axis (MGBA) and PSD, especially in the context of cerebral ischemia. In addition to the gut microbiota, another important factor is the gut barrier, which acts as a frontline sensor distinguishing between beneficial and harmful microbes, regulating inflammatory responses and immunomodulation. Based on this, this paper proposes a new approach, the microbiota-immune-barrier axis, which is not only closely related to the pathophysiology of IS but may also play a critical role in the occurrence and progression of PSD. This review aims to systematically analyze how the gut microbiota affects the integrity and function of the barrier after IS through inflammatory responses and immunomodulation, leading to the production or exacerbation of depressive symptoms in the context of cerebral ischemia. In addition, we will explore existing technologies that can assess the MGBA and potential therapeutic strategies for PSD, with the hope of providing new insights for future research and clinical interventions.

Improving hemodialysis patient depression outcomes with acupuncture: A randomized controlled trial

OBJECTIVE

To evaluate the efficacy and safety of acupuncture as a supplementary treatment for mild to moderate depression in hemodialysis patients.

METHOD

This multicenter, randomized, controlled, single-masked trial included 64 hemodialysis patients aged 18-75 divided into two groups. One group received genuine acupuncture, while the other received sham acupuncture over 12 weeks. The primary outcome measure was Hamilton Depression Scale (HAMD) scores; an inclusion criterion was HAMD scores of 10-23. Secondary outcomes included life quality improvements and changes in biochemical markers, such as serum albumin and hemoglobin levels. To assess the predictive effects of acupuncture treatment and biochemical parameters on depressive symptoms, a multivariable linear regression analysis was conducted.

RESULTS

Following acupuncture treatment, HAMD scores significantly decreased, quality of life scores improved, and biochemical indicators (serum albumin, hemoglobin, transferrin, and total protein levels) showed some improvement, indicating the effectiveness of acupuncture in alleviating depressive symptoms and enhancing overall health in hemodialysis patients. Multivariable regression analysis showed that acupuncture treatment (P = 0.004) and serum albumin levels (P = 0.03) were significant predictors of improvement in depressive symptoms, with an adjusted R2 of 0.45, indicating that the model explained 45 % of the variance in symptom improvement. Other biochemical indicators, such as hemoglobin, transferrin, and total protein, did not show significant predictive effects (P > 0.05). No serious adverse events were observed during the treatment.

CONCLUSION

Acupuncture is a safe and effective adjunct therapy for alleviating mild to moderate depression in hemodialysis patients. Acupuncture treatment and certain biochemical indicators (such as serum albumin) have significant predictive value for improving depressive symptoms.

The Role of Acupuncture of 13 Ghost Points Combined with Cognitive Therapy in Alleviating Liver-qi Stagnation Depression: A Clinical Study

ABSTRACT

Liver-qi stagnation-type depression, marked by irritability and emotional imbalance, often responds inadequately to medication alone. This study explored the efficacy of combining acupuncture at the 13 ghost points with cognitive therapy for this condition. Conducted at our hospital from January 2022 to January 2023, the study involved 76 patients with liver-qi stagnation-type depression, divided into an observation group (acupuncture + cognitive therapy) and a control group (fluoxetine tablets), with 38 patients in each group. We assessed clinical efficacy, Hamilton Depression Scale (HAMD) scores, Self-Rating Depression Scale (SDS) scores, Traditional Chinese Medicine (TCM) syndrome scores, liver-qi stagnation syndrome main symptom scores, and serum levels of 5-hydroxytryptamine (HT), vasoactive intestinal peptide (VIP), and cAMP response element-binding protein (CREB) before and after treatment. The observation group achieved a total effective rate of 81.58%, significantly higher than the control group ( P < 0.05). Both groups showed significant reductions in HAMD and SDS scores, TCM syndrome scores, and liver-qi stagnation syndrome principal symptom scores posttreatment, with the observation group demonstrating superior improvements ( P < 0.05). Serum levels of 5-HT, VIP, and CREB also increased significantly in both groups, with greater changes in the observation group ( P < 0.05). The results suggest that the combination of acupuncture and cognitive therapy is more effective than fluoxetine alone in treating liver-qi stagnation-type depression, improving both clinical symptoms and physiological indicators.

Unveiling synergies: Integrating TCM herbal medicine and acupuncture with conventional approaches in stroke management

This review explores the mechanisms and treatment strategies of ischemic stroke, a leading cause of morbidity and mortality worldwide. Ischemic stroke results from the obstruction of blood flow to the brain, leading to significant neurological impairment. The paper categorizes ischemic stroke into subtypes based on etiology, including cardioembolism and large artery atherosclerosis, and discusses the challenges of current therapeutic approaches. Conventional treatments like tissue plasminogen activator (tPA) and surgical interventions are limited by narrow windows and potential complications. The review highlights the promise of acupuncture, which offers neuroprotective benefits by promoting cerebral ischemic tolerance and neural regeneration. Integrating acupuncture with conventional treatments may enhance patient outcomes. Emphasis is placed on understanding the pathophysiology to develop targeted therapies that mitigate neuronal damage and enhance recovery.

Evaluating the effectiveness of integrated traditional Chinese and Western treatment based on symptom grading: a study protocol for a multi-center, randomized controlled trial of patients with depressive disorder

Background

Approximately one-third of depressed individuals receive treatment globally. The application rate of traditional Chinese medicine (TCM) for treating depression globally remains relatively low. The proposed study presents a pilot trial to evaluate the effectiveness of interventions at different levels in improving depression status in community populations.

Methods

A randomized controlled trial will be conducted in two communities in Guangdong, China, with a follow-up period of 12 weeks. Participants will be randomly allocated to control or intervention groups. Participants in the control group will be assigned to routine care, while participants in the intervention group will receive TCM intervention measures. The participants in the intervention group will receive integrated traditional Chinese and Western treatment according to the symptom grading of depression severity. Primary outcome measurements include the Patient Health Questionnaire (PHQ-9), the Hamilton Depression Rating Scale (HAMD-17), and the Self-Rating Depression Scale (SDS). Secondary outcome measurements include the Athens Insomnia Scale (AIS), the Epworth Sleepiness Scale (ESS), the Multiple Mental Health Literacy Scale (MMHL), the Short-Form 12 (SF-12), and the Treatment Emergent Symptom Scale (TESS). The data will be collected at baseline (T1), 2 weeks after intervention (T2), 4 weeks after intervention (T3), 8 weeks after intervention (T4), and 12 weeks after intervention (T5).

Discussion

This study will provide an experimental basis for the effectiveness of hierarchical integrated traditional Chinese and Western medicine (ITCWM) in improving the condition of patients with different degrees of depression. At the end of the study, it is expected for the experimental group to have an improvement in depressive symptoms and sleep quality and an enhancement in mental health awareness.

Efficacy of acupuncture therapy for spastic paralysis in post-stroke patients: a systematic review and meta-analysis

BACKGROUND

Despite the potentially good efficacy of acupuncture therapy in the management of post-stroke spastic paralysis demonstrated in previous studies, further verification through meta-analysis can be conducive to eliminating the inconclusive of treatment outcomes in prior findings. This systematic review and meta-analysis were thus performed to comprehensively investigate the effects of acupuncture on the daily living abilities, upper and lower limb motor function, and related functional indices of post-stroke patients with spastic paralysis.

METHODS

We conducted a computer search to collect data from PubMed, PEDro, Clinical SportDiscus, and Scopus. The inclusion criteria followed the Population-Intervention-Comparison-Outcome (PICO) principle. Literature screening, data extraction, and quality assessment of the research articles were performed by two independent investigators. Standard mean difference and 95% confidence intervals of the data were analyzed using either a random-effects model or a fixed-effects model.

RESULTS

Acupuncture therapy appeared to be effective in mitigating the limb pain of post-stroke patients with spastic paralysis (RR = -0.04, 95% CI: -0.26, 0.17), ameliorating their daily life ability (RR = 4.66, 95% CI: -0.74, 10.05), and improving their hand function (RR = 0.65, 95% CI: 0.40, 0.90) and lower limb function (RR = 0.35, 95% CI: 0.09, 0.62).

CONCLUSION

Acupuncture therapy provides more pronounced improvement in the daily life ability and limb motor function of post-stroke patients with spastic paralysis than conventional treatment regimens. Thus, acupuncture therapy can be a viable treatment option for the management of spastic paralysis following stroke.

Low frequency-repetitive transcranial magnetic stimulation combined with Xingnao Kaiqiao acupuncture improves post-stroke cognitive impairment and has better clinical efficacy

BACKGROUND

Enhancing post-stroke cognitive impairment (PSCI) is a key aspect of prognosis for stroke patients. Low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) is currently a widely utilised method for treating PSCI. With the increasing promotion of traditional Chinese medicine, Xingnao Kaiqiao (XNKQ) acupuncture has been progressively incorporated into clinical treatment. This paper observes the effect of LF-rTMS with XNKQ acupuncture on patients with PSCI.

METHODS

Totally, 192 patients with PSCI were consecutively recruited and treated either with LF-rTMS and XNKQ acupuncture (observation group) or LF-rTMS only (control group) for 4 weeks. The pre- and post-treatment Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores, P300 latency and amplitude, inflammatory factor levels were compared and clinical efficacy was assessed.

RESULTS

Both groups exhibited increased MMSE/MoCA scores, and P300 amplitude, and shortened P300 latency, and the observation group had higher scores and P300 amplitude, and shorter P300 latency than the control group. Both groups displayed decreased inflammatory factor levels (Tumour necrosis factor-α, interleukin (IL)-6, IL-10, IL-1β) after treatment, which were lower in the observation group than the control group. Inflammatory factor levels in PSCI patients were negatively interrelated with MMSE, MoCA score and P300 amplitude, and positively with P300 latency. The observation group showed an increased number of patients showing cured and significantly effective results, a decreased number of patients showing effective and invalid results, and an observably elevated total effective rate.

CONCLUSION

LF-rTMS with XNKQ acupuncture can improve cognitive function and reduce inflammatory immune response, and has better clinical efficacy in PSCI patients.

Effectiveness of acupuncture treatment in post-stroke depression and anxiety disorders: a prospective, randomized, controlled, single-blind study

OBJECTIVE

Our aim was to examine the effectiveness of acupuncture in post-stroke depression/anxiety disorders and to determine whether it reduces the need for anxiolytic and sedative drug use.

METHODS

This study included 54 stroke patients with depression and/or anxiety disorder. Patients were randomly assigned to the acupuncture treatment group (n = 27) or the control group (n = 27). A conventional rehabilitation program was applied to all patients and acupuncture was performed twice a week for 4 weeks. Patients were evaluated blindly by a psychiatrist at baseline (week 0), week 4 and week 8, using the Hamilton depression rating scale (HAM-D) and Hamilton anxiety rating scale (HAM-A), and drug doses were adjusted when necessary. The HAM-D and HAM-A scores at week 4 were pre-specified as the two primary outcome measures.

RESULTS

Within each group, there was a significant decrease in the mean scores of HAM-D and HAM-A at weeks 4 and 8. No between-group differences in HAM-A or HAM-D scores were seen at 4 weeks but there was a significant decrease in HAM-D scores in favor of the acupuncture group at week 8 (p < 0.025). At week 4, the number of cases whose selective serotonin reuptake inhibitor (SSRI) dose was increased was found to be significantly higher in the control group.

CONCLUSION

While the study was negative with respect to its primary outcomes, the findings with respect to certain secondary outcomes suggests further research is warranted to determine if acupuncture treatment is an effective/safe treatment to alleviate post-stroke depression/anxiety.

Clinical study of different frequency transcranial magnetic stimulation combined with paroxetine in the treatment of poststroke depression with insomnia

BACKGROUND

Study the treatment of poststroke depression and insomnia using varied repetitive transcranial magnetic stimulation (rTMS) frequencies alongside paroxetine. Aim to enhance rTMS effectiveness for depression, insomnia, neurological impairment, and daily living skills.

METHODS

Ninety poststroke depression (PSD) patients were randomly divided into a low-frequency group (low-frequency rTMS + enteric-coated paroxetine), a high-frequency group (high-frequency rTMS + enteric-coated paroxetine), and a control group (sham stimulation + enteric-coated paroxetine). The treatment was administered 5 times a week for a total of 2 weeks. Before treatment, at the end of the 2-week treatment, and at the end of the 6-week follow-up, the 3 groups of patients were assessed using the Hamilton Depression Rating Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), National Institutes of Health Stroke Scale (NIHSS), and Modified Barthel Index (MBI). The mean differences of scores measured at different frequencies and at different times were analyzed by repeated measure one-way analysis of variance.

RESULTS

The interaction between different frequency and score before and after treatment was significant. HAMD, PSQI, and NIHSS scores of the 3 groups after 2 weeks of treatment and 6 weeks of follow-up were significantly lower than before treatment, while MBI scores were opposite. The main effect of treatment scores in different frequency groups showed that HAMD, NIHSS, and MBI scores were not significantly different among the 3 groups before treatment. The HAMD, PSQI, and NIHSS scores of the low frequency group and the high frequency group were significantly lower than those of the control group after treatment, and the MBI scores were the opposite, except that there was no significant difference in HAMD-17 scores among the 3 groups at the 6-week follow-up. Among them, HAMD score in high-frequency group was significantly lower than that in low-frequency group, and PSQI score was significantly higher than that in low-frequency group.

CONCLUSION

Low-frequency rTMS combined with medication has a better therapeutic effect on the insomnia symptoms of PSD, while high-frequency rTMS combined with medication has a more pronounced therapeutic effect on the depressive symptoms of PSD. Both high-frequency and low-frequency rTMS have an improving effect on neurofunctional deficits and activities of daily living.

Effects of acupuncture combined with five-element music for people with mild/moderate post-stroke depression: A randomized controlled trial

OBJECTIVES

To evaluate the efficacy and safety of acupuncture combined with five-element music (FEM) as an therapeutic strategy for the physical and mental state of Post-stroke depression patients.

DESIGN AND SETTING

Multicenter, randomized clinical trial conducted at 3 hospitals in China and enrolling 237 patients with PSD between June 2019 and April 2021. Participants mild/moderate PSD (17-item GRID Hamilton Depression Scale (HAMD) score 7-24) were randomly assigned (1:1) to acupuncture combined with FEM (AFEM) group or cognitive behavioral therapy (CBT) group.

MAIN OUTCOME MEASURES

The primary outcome was change and differences between the groups in HAMD-17 from baseline to week 12. Secondary outcomes included Fugl-Meyer Assessment Scale score and Stroke-Specific Quality of Life Scale (SS-QOL) score.

RESULTS

The 237 patients in this intention-to-treat analysis were randomized into either the AFEM group (n=119) or the cognitive behavioral therapy (CBT) group (n=118). Of these 237 participants, 225 (94.9 %) completed all outcome measurements at week 12. The AFEM and CBT groups both showed significant improvement in HAMD-17 from baseline to week 12. Patients in the AFEM group had significantly lower HAMD-17 scores of -3.56 at week 8 (95 % CI,-4.59 to -2.53; p <.001) and -3.50 at week 12 (95 % CI,-4.53 to -2.46; p<.001) than patients in the CBT group. The SS-QOL score improved significantly at week 12. The Fugl-Meyer score was significantly lower in the AFEM group than in the CBT group at week 4, but this difference was not statistically significant upon follow-up at weeks 8 and 12. The incidence of treatment-related adverse events was 2.1 % in the AFEM group, with no serious adverse events reported.

CONCLUSIONS

The results suggest that acupuncture and five-element music significantly improve the depressive symptoms in this cohort of Chinese PSD patients, and the toxicities were similar with CBP group.

Acupuncture may play a key role in anti-depression through various mechanisms in depression

Depression has emerged as a significant global health concern, exerting a profound impact on individuals, as evidenced by its high prevalence and associated suicide rates. Considering its pervasive nature, the absence of optimal treatment modalities remains a challenge. Acupuncture has garnered substantial clinical and experimental validation for its efficacy in addressing diverse forms of depression, including postpartum, post-stroke, and adolescent depression. This article endeavors to elucidate the distinctive attributes and underlying mechanisms of acupuncture in the contemporary treatment of depression. Research has demonstrated that acupuncture exerts diverse physiological effects in animal models of depression, encompassing modulation of the brain, serum, and brain-gut axis. These effects are attributed to various mechanisms, including anti-inflammatory and anti-oxidative actions, promotion of neuronal plasticity, neuroprotection, neurotrophic effects, modulation of neurotransmitters, regulation of endocrine and immune functions, and modulation of cell signal pathways. Currently, the therapeutic mechanism of acupuncture involves the engagement of multiple targets, pathways, and bidirectional regulation. Hence, acupuncture emerges as a promising alternative medical modality, exhibiting substantial research prospects and meriting comprehensive worth further study and dissemination.

Electroacupuncture ameliorates depression-like behaviors in rats with post-stroke depression by inhibiting ferroptosis in the prefrontal cortex

Introduction

Post-stroke depression (PSD) is the most common complication following a stroke, significantly hindering recovery and rehabilitation in affected patients. Despite its prevalence, the pathogenesis of PSD remains poorly understood. Electroacupuncture (EA) has shown antidepressant effects, yet its neuroprotective properties are not well defined. Ferroptosis, a recently identified form of cell death, is implicated in the pathological processes of stroke and is associated with the development of depression-like behaviors. So we aimed to investigate whether PSD induces ferroptosis, identify potential therapeutic targets within these pathways, and elucidate the underlying mechanisms in this study.

Methods

Male Sprague-Dawley rats were subjected to middle carotid artery occlusion and chronic unpredictable mild stress to model PSD. To explore the role of ferroptosis in the effects of EA, the ferroptosis inducer erastin was administered into the rats' lateral ventricles, followed by 14 days of EA treatment, with sessions lasting 30 minutes per day. The Zea-Longa score was used to assess neurological deficits, while the sucrose preference test, elevated plus maze test, and open-field test were employed to evaluate depression-like behaviors in the rats. Hematoxylin-eosin, Nissl, and Perl's staining were used to observe the morphological changes and iron deposition in the prefrontal neurons. Transmission electron microscopy provided detailed observations of mitochondrial morphological changes in neurons. We utilized activity assay kits, enzyme-linked immunosorbent assay (ELISA), and Western blotting to explore potential molecular mechanisms underlying the effects of EA.

Results

EA can reduce neurological deficits and enhance the spontaneous activity and exploration behavior of rats. In addition, EA could inhibit prefrontal cortex neuronal ferroptosis by reducing iron deposition, decreasing lipid peroxidation, and enhancing antioxidation.

Discussion

EA improved depression-like behaviors, mitigated mitochondrial damage, and inhibited ferroptosis in prefrontal cortex neurons. Notably, the administration of erastin further enhanced these effects. In conclusion, EA appears to improve PSD by inhibiting ferroptosis in the prefrontal cortex.

Effect of Acupuncture on Cognitive Function in Patients With Post-Stroke Cognitive Impairment: A Systematic Review and Meta-Analysis

AIMS AND OBJECTIVE

To investigate the impact of acupuncture on post-stroke cognitive impairment (PSCI).

BACKGROUND

PSCI is a major barrier to stroke patients' rehabilitation, and acupuncture is one of the treatments. However, the benefit of acupuncture on PSCI is unclear.

DESIGN

A meta-analysis and systematic review of randomized controlled trials (RCTs).

METHODS

Up to February 1, 2024, databases in PubMed, MEDLINE, Scopus, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, VIP, and Wanfang Data were searched. The risk of bias was investigated using the Cochrane Handbook for systematic reviews of treatments. Random-effect and fix-effect models were used to report the effects.

RESULTS

There were 29 randomized clinical trials with 2477 participants included. The findings demonstrated that the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) scores were higher in the acupuncture group than medicine group (mean difference [MD] = 1.74, 95% confidence interval (CI) CI [1.26, 2.23], I2 = 59%, p < 0.01). Compared to medicine group, the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) score exhibited a significant decrease and demonstrated improvement in the acupuncture group. Statistically significant outcomes were observed in the Barthel Index scores and P300 event-related potential (ERP). According to subgroup analysis, acupuncture was superior to conventional therapy for improving cognitive function in PSCI patients at 4 weeks after treatment.

CONCLUSION

Acupuncture therapy has shown promise in ameliorating cognitive deficits and enhancing daily functional abilities in individuals diagnosed with PSCI. But future research should focus on the duration and implement large sample, high-quality RCTs.

RELEVANCE TO CLINICAL PRACTICE

Clinical workers in practical clinical work can select appropriate acupoints according to the actual conditions of patients, as well as confirm the treatment course of PSCI patients, while paying attention to observing and evaluating the therapeutic efficacy of acupuncture, to improve the health outcomes of patients in a patient-centered way.

Effectiveness of non-pharmacological therapies for treating post-stroke depression: A systematic review and network meta-analysis

OBJECTIVE

Post-stroke depression (PSD) is a common neurological and psychiatric sequelae following a stroke, often surpassing the primary effects of the stroke due to its strong correlation with high mortality rates. In recent years, non-pharmacological therapy has garnered significant attention as a supplementary treatment for PSD, becoming widely adopted in clinical practice. However, the efficacy of specific intervention strategies remains unclear. This study aimed to conduct a network meta-analysis (NMA) of published studies to compare the efficacy of different non-pharmacological therapies for treating PSD.

METHOD

We systematically searched five databases from inception through March 2024 to identify randomized controlled trials (RCTs) evaluating non-pharmacological therapies for the treatment of PSD. We considered individual intervention and intervention class. Intervention classes included traditional Chinese medicine (TCM), non-invasive electrotherapy stimulation (NIES), psychotherapy (PT), exercise therapy, hyperbaric oxygen, and combined interventions. The NMA was conducted using R and Stata software, following a frequency-based methodology. Assessment of methodological quality and risk of bias was conducted using the Risk of Bias assessment tool 2.0. Therapies were ranked using the P-score, and box-plots visualization, meta-regression, and sensitivity analysis, were performed to assess transitivity, heterogeneity, and consistency, respectively.

RESULTS

The NMA included 43 studies with a total of 3138 participants. Random-effects models revealed significant efficacy for acupuncture (ACUP) (P-score = 0.92; pooled standardized mean difference (95% CI): -3.12 (-4.63 to -1.60)) and transcranial direct current stimulation (P-score = 0.85; -2.78 (-5.06 to -0.49)) compared to the treatment as usual (TAU) group. In categorical comparisons, TCM_PT (P-score = 0.82; -1.91 (-3.54 to -0.28)), TCM (P-score = 0.79; -1.65 (-2.33 to -0.97)), and NIES (P-score = 0.74; -1.54 (-2.62 to -0.46)) showed significant differences compared to TAU group. Furthermore, our results indicated no significant difference between PT and the control groups. However, Confidence in Network Meta-Analysis results indicated very low overall evidence grade.

CONCLUSION

Limited evidence suggests that ACUP may be the most effective non-pharmacological therapy for improving PSD, and TCM_PT is the best intervention class. However, the evidence quality is very low, underscoring the need for additional high-quality RCTs to validate these findings, particularly given the limited number of RCTs available for each therapy.

Global research trends in acupuncture treatment for post-stroke depression: A bibliometric analysis

OBJECTIVE

Post-stroke depression (PSD) is a prevalent and severe sequela of stroke. It is an emotional disorder that significantly impacts functional recovery, prognosis, secondary stroke risk, and mortality among stroke survivors. The incidence rate of PSD is 18 %∼33 %, with symptoms such as low mood, decreased interest, sleep disorders, decreased appetite, impaired attention, and in severe cases, hallucinations and even suicidal tendencies. While diverse therapeutic modalities are employed globally to address PSD, each approach carries its inherent advantages and limitations. Notably, acupuncture stands out as a promising and effective intervention for ameliorating PSD symptoms and enhancing stroke prognosis. This study aims to conduct a bibliometric analysis to scrutinize the current landscape, identify hotspots, and explore frontiers in acupuncture research for PSD.

METHODS

A systematic search for acupuncture and PSD-related research was conducted from January 2014 to October 2023 on the Web of Science Core Collection (WoSCC). The data were downloaded and processed using Bibliometrix and VOSviewer to generate knowledge visualization maps.

RESULTS

A total of 11,540 articles related to acupuncture and PSD were retrieved. China emerged as the leading contributor with the highest volume of articles on acupuncture and PSD. Author Liu CZ attained the highest H-index, focusing primarily on investigating the compatibility effects and mechanisms of acupoints. Common hotspot keywords included pain, stimulation, mechanisms, complementary, and alternative medicine. The main research frontiers were mechanisms, neuroinflammation, gut microbiota, and therapeutic methods.

CONCLUSION

This study offered multifaceted insights into acupuncture for PSD, unveiling pivotal areas, research hotspots, and emerging trends. The findings aimed to guide researchers in exploring novel research directions and selecting appropriate journals for advancing the understanding and treatment of PSD through acupuncture interventions.

Serum Levels and Clinical Significance of NSE, BDNF and CNTF in Patients with Cancer-associated Ischemic Stroke Complicated with Post-stroke Depression

BACKGROUND

The incidence of post-stroke depression (PSD) may be higher in patients with cancer-associated ischemic stroke (CAIS). The pathogenesis of PSD is mainly related to the emotional injury of stroke and the inability of neurons to effectively repair. This study aims to explore the clinical significance of serum neuron-specific enolase (NSE), brain-derived neurotrophic factor (BDNF) and ciliary neurotrophic factor (CNTF) expression levels in CAIS patients.

METHODS

Clinical data of 106 patients with CAIS admitted to Jinhua Guangfu Oncology Hospital from January 2012 to December 2022 were retrospectively analyzed. Serum levels of NSE, BDNF and CNTF were measured in all patients after admission. Depression screening was performed by Hamilton Depression Scale-17 (HAMD-17) three months after intravenous thrombolysis. Patients with HAMD-17 score >7 were included in the PSD group (n = 44), and patients with HAMD-17 score ≤7 were included in the non-PSD group (n = 62). The general data and serum levels of NSE, BDNF and CNTF were compared between the two groups. According to HAMD-17 scores, patients in PSD group were further divided into mild depression group (8-16 points), moderate depression group (17-23 points) and severe depression group (≥24 points), and the serum levels of NSE, BDNF and CNTF were compared among the three groups. Pearson's correlation test was used to analyze the correlation between HAMD-17 scores and serum NSE, BDNF and CNTF levels in PSD patients. Logistic regression model was used to determine the influencing factors of PSD in CAIS patients. Receiver operating characteristic (ROC) curve was plotted to analyze the predictive efficacy of serum NSE, BDNF, CNTF and their combination on PSD.

RESULTS

Among 106 CAIS patients, the incidence of PSD was 41.51% (44 cases), including 19 patients with mild PSD (43.18%), 14 patients with moderate PSD (31.82%), and 11 patients with severe PSD (25.00%). There were statistically significant differences in negative life events and complications after thrombolytic therapy between PSD and non-PSD patients (p < 0.05). The serum NSE level in PSD group was significantly higher than that in non-PSD group, and the serum BDNF and CNTF levels were notably lower than those in non-PSD group (all p < 0.001). The serum levels of NSE, BDNF and CNTF in patients with different severity of PSD were statistically significant (all p < 0.001). HAMD-17 scores in PSD patients were positively correlated with serum NSE levels (r = 0.676, p < 0.001) and negatively correlated with serum BDNF and CNTF levels (r = -0.661, p < 0.001; r = -0.401, p = 0.007, respectively). By binary logistic regression analysis, the levels of serum NSE, BDNF and CNTF were independent influencing factors for PSD in CAIS patients, among which NSE was a risk factor (odds ratio (OR) >1, p < 0.05), BDNF and CNTF were protective factors (OR <1, p < 0.05).

CONCLUSION

This study reveals for the first time that the levels of serum NSE, BDNF and CNTF are closely related to the occurrence and development of PSD in CAIS patients. In clinical CAIS patients with abnormal changes in the above indicators, in addition to anti-tumor treatment and improvement of neurological deficit symptoms, attention should also be paid to the symptoms of psychological disorders.

All Palliative Care Should Be Integrative Palliative Care

Integrative medicine and palliative care are philosophically similar, with a focus on whole person care and wellbeing. Integrative medicine provides a large toolbox of evidence-informed treatment modalities but doesn't prioritize the care of seriously ill people. Palliative care takes a holistic approach to reducing the suffering of seriously ill people, their families, and their caregivers, but the available treatment toolbox is often limited to pharmaceuticals, procedures, and radiation. The ideal care of families facing serious illness employs the philosophy and conventional expertise of palliative care clinicians coupled with an evidence-supported expanded treatment toolbox provided by the field of complementary and integrative medicine. This emerging field is called integrative palliative care. Reducing physical, emotional, and spiritual suffering is the fundamental goal of palliative care and all available effective tools should be employed toward this aim. Therefore, all palliative care should be integrative palliative care.

Optimal acupuncture methods for lower limb motor dysfunction after stroke: a systematic review and network meta-analysis

Background

The lower limb motor dysfunction caused by stroke is one of the main sequelae affecting patients' ability to live normally in the later period. Acupuncture treatment of limb movement dysfunction after stroke has been recommended by authoritative guidelines for reducing limb spasticity, enhancing limb strength and so on. However, the efficacy of different acupuncture methods in treating lower limb motor dysfunction after stroke remains controversial.

Objective

In this paper, network meta-analysis (NMA) was used to prioritize various acupuncture intervention combinations commonly used in clinical practice, try to screen the acupuncture intervention scheme with the highest clinical efficacy and safety, and explore its rationality in guiding clinical practice.

Methods

We searched a total of 4,312 studies from 8 databases and 2 clinical trial registries, and selected 43 articles for systematic review. We used pairwise meta-analysis and network meta-analysis to evaluate the efficacy and ranking of various acupuncture interventions. At the same time, the risk of bias, publication bias, and sensitivity of included randomized controlled trials were analyzed. The main outcome indicator was Fugl-Meyer assessment of lower extremity (FMA-LE), and the secondary outcome indicators were Modified Barthel Index (MBI), Berg balance scale (BBS) and Modified Ashworth scale (MAS).

Results

A total of 4,134 patients in 43 studies were included. The intervention included 9 acupuncture-related treatments, of which 20.9% were classified as high-risk. Among the four outcome indicators in pairwise meta-analysis, the effect of body acupuncture combined with conventional rehabilitation has the highest comprehensive credibility in terms of efficacy and safety comparing with conventional rehabilitation [SMD = 1.14, 95%CI (0.81, 1.46)], [SMD = 1.35, 95%CI (0.97, 1.72)], [SMD = 1.22, 95%CI (0.39, 2.05)], [SMD = 1.21, 95%CI (0.74, 1.44)]. In addition, multiple intervention methods, for example, warm acupuncture plus rehabilitation treatment for MBI and electroacupuncture plus body acupuncture plus rehabilitation treatment for BBS, may increase certain additional effects on different outcome indicators.

Conclusion

This study proves that body acupuncture combined with rehabilitation treatment is the most widely used intervention method with the highest evidence quality in the treatment of lower limb motor dysfunction after stroke. However, for some other acupuncture methods, large samples and high-quality clinical randomized controlled trials are still needed to be fully verified.

Bibliometric Analysis: Research Trends and Performances of Stroke on Acupuncture

PURPOSE

This study aimed to apply the bibliometric analysis to summarize acupuncture therapy for stroke, demonstrated and evaluated the trends, major research hotspots and frontier areas.

MATERIALS AND METHODS

Articles on acupuncture for stroke were selected from the Web of Science Core Collection (WoSCC) from the inception of the database up until 2023. CiteSpace software was performed to conduct the collaborative analysis of networks of countries, institutions, authors and cited authors, journals and cited journals, cited references, keywords clustering and burstiness analysis.

RESULTS

A total of 1141 articles were retrieved. China was the most productive country (851) and had the greatest centrality (0.43). Beijing Univ Chinese Med (86) contributed to the most publications. Chen LD (31) and Tao J (31) were the most prolific authors, of which all from Fujian Univ Tradit Chinese Med. Wu P (124) from Canadian College of Naturopathic Medicine, Canada, was the most cited author. Evidence-based Complementary and Alternative Medicine (89) was the most productive journal, while Stroke (744) was first cited journals. Stimulation, recovery, ischemic stroke, electroacupuncture, rehabilitation were the most high-frequency keywords. Future research in this area will pay more attention to the evaluation of the effectiveness of acupuncture therapeutics in treating stroke, conducting the clinical research on cognitive ability, quality of life and partial function of stroke patients, and basic research related to mechanisms.

CONCLUSION

The publications on acupuncture in stroke have shown major development, but the international cooperation for academic exchange among researchers and institutions remained to be strengthened to promote interdisciplinary and academic innovation. Furthermore, except for the molecular mechanism of acupuncture in treating functional rehabilitation of stroke, exploring the more high-quality clinical studies may become a key point based on the evidence-based medicine.

Perceptions, Attitudes, Beliefs, and Practices Toward Traditional Chinese Medicine Therapies for Herpes Zoster: A Cross-Sectional Study of Healthcare Professionals

Introduction

Traditional Chinese medicine (TCM) holds great potential in promoting healing and relieving pain for herpes zoster (HZ) treatments. Evidence showed that both healthcare professionals' (HCPs) belief and knowledge influence their attitudes, which result in their expression and direct behavior. However, little is known in this area regarding TCM treatments for HZ. This study aimed to understand the HCPs' perceptions, attitudes, beliefs, and practices toward TCM and its services for HZ.

Methods

During July 2021 and October 2022, a cross-sectional study of HCPs querying demographics, perceptions, attitudes, beliefs, and practices toward TCM and TCM services for HZ was conducted. The frequency and percentage or mean and standard deviation were used to present categorical data and continuous data, respectively. A Chi-square analysis compared nurses' and doctors' views on TCM treatments for HZ.

Results

Out of 306 eligible respondents, 66.0% used TCM content in clinical practice less than 40% of the time. Respondents reported that there were three main advantages of TCM for HZ, including better crusting and healing, fewer side effects, and mitigating complications. A total of 41.3% (81/196) of the respondents who had cared for/treated HZ patients applied TCM treatments. The three factors most associated with referrals/providing TCM to patients were postherpetic neuralgia, early erythema or papules, and acute pain. Compared to nurses, doctors showed more endorsement of the efficacy and cost-effectiveness of TCM treatments for HZ patients.

Conclusion

The study found that most healthcare professionals in HZ had a favorable view of TCM, but lacked practical experience administering it to patients. Programs should be developed to provide evidence-based TCM treatments and encourage combining TCM with Western medicine for better patient care.

Efficacy and safety of acupuncture treatment for post-stroke depression: A protocol for systematic review and meta-analysis

BACKGROUND

Post-stroke depression is a common complication of stroke, with a high incidence rate and low recognition rate. Many patients do not receive effective intervention at the onset, which affects subsequent treatment outcomes. Post-stroke depression not only impacts the patient's mental well-being but also increases the risk of stroke recurrence and poor prognosis. Therefore, it has become a significant public health concern. Acupuncture has gained significant popularity in the treatment of post-stroke depression. However, there are inconsistent clinical research results regarding its efficacy and safety. This systematic review aims to gather and critically assess all available evidence regarding the effectiveness and safety of acupuncture in the treatment of post-stroke depression in patients.

METHODS

We will conduct thorough searches for relevant studies in multiple electronic databases (PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP Database, Wan-fang Data and China Biomedical Database). Our search scope will encompass studies published from the inception of each database until September 2023. To evaluate the potential bias in all the included studies, we will adhere to the guidelines offered in the Cochrane Handbook. The total effective rate will be the primary outcome. To conduct a systematic review, we will employ RevMan 5.4 software.

RESULTS

This study will obtain efficacy and safety of acupuncture for the treatment of post-stroke depression.

CONCLUSIONS

The conclusions of this study will provide evidence-based perspectives that can guide clinical decision-making regarding the practicality and recommended timing of using acupuncture to treat post-stroke depression. Furthermore, this study will help advance the clinical application of acupuncture treatment for post-stroke depression and enhance its efficacy while ensuring patient safety.

Global trends and development of acupuncture for stroke: A review and bibliometric analysis

The objective of this review is to elaborate on the status, hotspots, and trends of researches on acupuncture for stroke over the past 26 years. Publications about acupuncture for stroke were downloaded from the Web of Science Core Collection, and these papers were published up to December 31, 2022. A bibliometric analysis of acupuncture for stroke was conducted by CiteSpace (6.2.R4) and VOSviewer (1.6.17). In this study, VOSviewer was used for visual analysis of countries, institutions, authors, journals, keywords, and co-cited references. CiteSpace was used to draw a keyword burst map and a co-cited reference burst map. A total of 534 papers were obtained from the Web of Science Core Collection. The number of papers per year showed a rapid upward trend. The most productive country and institution in this field were China (452) and the Fujian University of Traditional Chinese Medicine (43), respectively. Tao Jing had the highest number of articles (34), and EZ Longa was the most popular author (129 co-citations). Neural Regeneration Research (51) was the most productive journal, and Stroke (1346) was the most co-cited journal. An paper written by EZ Longa was the most influential reference, with the highest citation count. The hotspots and frontiers of this area of research were focused on the mechanisms of acupuncture, especially its neural regenerative or neuroprotective effects. This study used CiteSpace and VOSviewer for bibliometric analysis to provide researchers with information on the research status, hotspots, and trends in acupuncture for stroke research over the past 26 years.

Does acupuncture treatment modulate inflammatory cytokines in rodent models of depression? A systematic review and meta-analysis

Background

Despite the increasing global prevalence of depression, existing treatment methods have limitations. Acupuncture has been recognized for its potential to alleviate various diseases by regulating inflammatory cytokines. However, a comprehensive systematic analysis of the effects of acupuncture on depression through inflammatory cytokines is currently lacking. This review aims to evaluate the impact of acupuncture on inflammatory cytokines in animal models of depression.

Methods

A comprehensive search was conducted in PubMed, EMBASE, MEDLINE, and the Research Information Service System to identify studies that met predefined inclusion and exclusion criteria. The quality of each included study was assessed using a 10-item checklist adapted from the Cochrane Collaboration methods and animal data review. Meta-analysis was performed using STATA 17.0 software for literature that met the inclusion criteria.

Results

The meta-analysis included a total of 21 studies involving 376 rodents. The overall quality of the included reports was rated as moderate or higher. The results demonstrated that acupuncture had a significant effect on the reduction of pro-inflammatory cytokines, including: IL-1β [SMD = 3.36, 95% CI (2.73, 4.00), I2 = 73.3%, p < 0.05], IL-6 [SMD = 3.05, 95% CI (2.45, 3.64), I2 = 68%, p < 0.05], and TNF-α [SMD = 3.30, 95% CI (2.53, 4.06), I2 = 74.5%, p < 0.05]. Conversely, acupuncture was associated with an increased expression of anti-inflammatory cytokines, notably: IL-4 [SMD = -1.64, 95% CI (-2.46, -0.82), I2 = 4.1%, p = 0.307] and IL-10 [SMD = -1.45, 95% CI (-2.24, -0.66), I2 = 0, p = 0.678]. These results suggest that acupuncture modulates cytokine levels in depressed rodents, including reducing the expression of pro-inflammatory cytokines and increasing the expression of anti-inflammatory cytokines, thereby regulating the immune-related antidepressant pathway.

Conclusion

While this study is limited by the number of included studies, the results suggest that acupuncture may be a viable option for the treatment of depression, and this effect is achieved through the regulation of various inflammatory cytokines.

Effects and central mechanism of electroacupuncture and MRI-navigated rTMS for PSD: study protocol for an fMRI-based single-center, randomized, controlled, open-label trial

Background

Post-stroke depression (PSD) is the most common mental complication after stroke and has a serious impact on functional outcomes and quality of life for stroke patients. Antidepressants are the first-line treatment for PSD; however, many reported side effects remain. Clinical research and practice guidelines have shown that electro-acupuncture (EA) or rTMS have a positive effect on PSD. However, there are few clinical studies on EA and MRI-navigated rTMS for PSD that explore the fMRI-based central mechanism in depression.

Methods

In this randomized, controlled, open-label trial, 64 patients with PSD will be randomly allocated into the experiment group (n = 32) or control group (n = 32). The experiment group will receive EA and MRI-navigated rTMS and the control group will receive MRI-navigated rTMS treatment, in 12-20 sessions over 4 weeks. In addition, 10 healthy people for fMRI scanning will be recruited as a healthy control group without any intervention. The primary outcome will be the change from baseline in the Hamilton Depression Scale-24 item (HAMD-24) scores at week 4. The primary analysis of the central mechanism will mainly involve cortical morphology, local spontaneous brain activity, and the default mode network (DMN) functional connectivity based on fMRI at 0 and 4 weeks. Secondary outcomes will include the neuro-patho-physiological and quality of life changes in cortical excitability, determined using the motor evoked potential test (MEP), National Institutes of Health Stroke Scale (NIHSS), EuroQol Five Dimensions Questionnaire (EQ-5D) Scale, Modified Barthel Index (MBI) Scale, and Health Scale of Traditional Chinese Medicine (HSTCM). Additional indicators will include the Acceptability Questionnaire and Health Economics Evaluation (cost-effectiveness analysis) to assess the acceptability and economic practicality of the treatment under study. Outcomes will be assessed at baseline and post intervention.

Discussion

EA and MRI-navigated rTMS therapy could become an alternative treatment for PSD, and it is expected that this trial will provide reliable clinical evidence and a potential central mechanism for the future use of EA and MRI-navigated rTMS for PSD.
